Description

  The present invention relates to a harvester such as a combine harvester or a root vegetable harvester such as a carrot harvester or a radish harvester, or an onion harvester.

Conventionally, in the harvesting machine as described above, the fuel tank is placed on the horizontal frame of the machine frame so as to be positioned directly above the crawler type traveling device (see, for example, Patent Document 1).
Japanese Patent Laying-Open No. 2003-200742 (paragraph number 0012, FIGS. 1 and 3)

  By the way, for example, when the harvester is transported to an agricultural field such as a mountainous area, a small transport vehicle such as a light truck may have to be used for the transportation due to the road conditions peculiar to the mountainous area. Therefore, if the harvesting machine as described above is configured to have a size that can be loaded on the loading platform of a small transport vehicle, the versatility can be used even in fields such as mountainous areas.

  On the other hand, harvesters such as combine harvesters have recently been equipped with large working devices to improve work efficiency. However, as in the conventional structure described above, the fuel tank is mounted on the fuselage frame. The size of the working device to be equipped by the fuel tank is restricted.

  In other words, in the harvesting machine having the above-described conventional structure, it has been difficult to improve work efficiency while being small and highly versatile that can be used in fields such as mountainous areas.

  An object of the present invention is to make it possible to improve work efficiency while making it small and highly versatile, which can be used in fields such as mountainous areas.

As means for solving the above-mentioned problems, in the present invention, an engine bonnet having a driver's seat arranged at the front is provided on the right front part of the traveling aircraft body, and a fuel tank is provided at a position above the rear part of the engine bonnet. The engine bonnet has a left and right support member at the upper front end of the engine bonnet, and the end of the support member in the left and right direction is connected to the engine bonnet through a front and rear connection pin, and the connection pin is used as a fulcrum. The support member is configured to be able to swing up and down, the left and right support portions extending upward from the support member are provided in the support member, and the left and right support portions are supported above the left and right support portions. The bottom front end portion of the driver seat is connected via a shaft so that the driver seat can swing back and forth with the support shaft as a fulcrum.

  According to this configuration, the space behind the driver seat above the engine bonnet is effectively used as the fuel tank arrangement space, so that the size of the work device to be equipped is not restricted by the fuel tank.

  In other words, it is possible to reduce the size of the combine as a whole while providing a large working device.

  Moreover, the feed pump can be dispensed with by arranging the fuel tank at a high position above the engine bonnet.

  Therefore, the working efficiency can be improved and the fuel supply structure can be simplified while being small and highly versatile that can be used in fields such as mountainous areas.

In addition, by displace the driver's seat to the front side, it can be avoided that the driver's seat gets in the way when refueling the fuel tank, and when the replenishment tank is used when refueling, the engine The bonnet can be used as a temporary storage base for the supply tank.

Therefore, it becomes easy to refuel the fuel tank arranged behind the driver seat above the engine bonnet.

As one of means for making the present invention more suitable, the support member is formed in an angle shape in a side view along a corner of the upper front end of the engine bonnet, and an airframe of a front plate portion of the support member An end portion on the inner side in the left-right direction is connected to the front side of the engine bonnet via the connecting pin, and an engagement pin provided on the front side of the engine bonnet is connected to an end portion on the outer side in the left-right direction of the body of the support member. A hook that can be engaged is provided.

As a means for the present invention to more suitable, wherein a fuel tank is fixed to the fixed portion of the vehicle body, the engine bonnet, displaced from the working position covering the engine to the body outside The engine can be changed to a maintenance attitude that opens the engine.

  According to this configuration, since the fuel tank does not need to be supported by the engine bonnet when the fuel tank is disposed above the engine bonnet, a reinforcing structure for the engine bonnet that is required when the fuel tank is supported by the engine bonnet is unnecessary. Can be.

  In addition, it is possible to avoid complication of the piping structure by adopting a piping structure that allows the displacement of the fuel tank accompanying the change in the attitude of the engine bonnet, which occurs when the fuel tank is mounted on the engine bonnet that can change the attitude. This is advantageous in terms of operability when changing the posture of the engine bonnet, and makes it easier to perform maintenance on the engine in the engine bonnet.

  Therefore, the structure can be simplified, and the engine bonnet can be easily changed in posture and easily maintained.

Above the waste straw shredding device 6, a waste straw transporting device that receives the waste straw after the threshing process from the feed chain 24 and transports it to the supply position for the waste straw shredding device 6 is provided.

  As shown in FIGS. 1, 2, 4 to 7, 11, and 12, the engine room 8 responds to an increased work load due to an increase in processing speed, an increase in the size of the threshing device 4, and the like. A high-power engine 40 that can be produced is arranged in such a posture that its output shaft 41 is directed forward and backward. The engine 40 is a water-cooled diesel engine, and a cooling fan 42 that is driven by power from the output shaft 41 is provided at the front thereof, and the cooling fan 42 is driven in front of the cooling fan 42. A radiator 43 cooled by the flowing cooling outside air is provided in the front-rear direction, an air cleaner 44 is provided in the lower right side of the radiator 43 in the front-rear direction, and a muffler 45 is provided in the rear side of the air cleaner 44 in the up-down direction. Yes. Behind the engine 40, a belt tension type first transmission mechanism 46 and a belt tension type threshing clutch 47, which are connected to the rear end portion of the output shaft 41, are arranged side by side.

  That is, by disposing the engine 40, the radiator 43, and the like in the engine room 8 as described above, for example, the engine 40 is disposed in a posture in which the output shaft 41 is directed left and right. Compared to the case where the radiator 43 and the like are arranged on the side, and the first transmission mechanism 46 and the like are arranged on the left and right sides of the engine 40, the left and right lengths of the driving unit including the engine 40 and the radiator 43 can be shortened. As a result, it is possible to use a large engine 40 with higher output, and as a result, the overall left and right width of the combine as a whole is narrow enough to be loaded on the loading platform of a small transport vehicle such as a light truck, and more output is achieved. Can be equipped with a large, large engine 40, which responds to an increase in processing speed and an increase in work load due to an increase in the size of the equipped threshing device 4 Come, so that thereby improving the work efficiency.

  As shown in FIGS. 7 to 9, 12, and 13, the shift lever 14 swings in the left-right direction at a position located on the left side of the engine 40 in the traveling machine body 1 and below the right rear portion of the cutting and conveying unit 3. A transmission case 49 having a built-in gear-type transmission 48 that is operated in conjunction with the operation is installed upright. A rear upper portion of the transmission case 49 is interlocked with a swinging operation of the shift lever 14 in the front-rear direction. The hydrostatic continuously variable transmission 50 that is operated in a shifting manner is connected and installed with the input shaft 51 extending backward, and the transmission case 49 and the hydrostatic continuously variable transmission 50 are connected to the engine 40. It is arranged on the front side of the aircraft from the rear end. The gear transmission 48 and the hydrostatic continuously variable transmission 50 constitute a transmission in this combine.

  The hydrostatic continuously variable transmission 50 has a belt-tension-type second transmission mechanism 53 at the front end portion of the first relay shaft 52 that faces forward and backward, and whose input shaft 51 is disposed close to the lower left rear portion of the engine 40. It is linked and connected through. The rear end of the first relay shaft 52 is linked to the output shaft 41 of the engine 40 via the first transmission mechanism 46. That is, the hydrostatic continuously variable transmission 50 is configured to shift the power from the engine 40. Since the hydrostatic continuously variable transmission 50 is disposed on the front side of the fuselage with respect to the rear end of the engine 40, the second transmission mechanism 53 connected to the input shaft 51 is also more than the rear end of the engine 40. It will be located on the front side of the aircraft.

  As shown in FIG. 13, the gear-type transmission 48 includes a pair of bevel gears (powers) that convert rotational power around the longitudinal axis from the hydrostatic continuously variable transmission 50 into rotational power around the lateral axis. A converter 54) and outputs the converted power.

  In other words, the internal space of the mission case 49 is effectively used to convert the power around the longitudinal axis from the hydrostatic continuously variable transmission 50 into the power around the lateral axis. Compared with the case where a dedicated power conversion mechanism is provided, the configuration can be simplified and the overall size of the combine can be avoided.

  The gear-type transmission 48 is configured to shift the power after shifting by the hydrostatic continuously variable transmission 50 to two levels. Under the transmission case 49, the transmission state from the gear type transmission 48 to the corresponding crawler type traveling device 7 is switched and the corresponding crawler type traveling device 7 is switched based on the swinging operation of the control lever 12 in the left-right direction. The left and right side clutch brake devices 55 that can be switched to a braking state are incorporated.

  That is, by the swinging operation of the control lever 12 in the left and right direction, the left and right crawler type traveling device 7 is driven straight and the left and right crawler type traveling devices 7 are driven, and the left and right other crawler type traveling devices 7 are driven. 7 is switched to a slow turning state in which the left and right crawler type traveling devices 7 are driven and the left and right other crawler type traveling devices 7 are stopped.

  As shown in FIGS. 1, 8, 12, and 13, the left and right crawler type traveling devices 1 each have a left and right drive shaft 57 that drives a drive sprocket 56 disposed at the front end thereof. The drive shafts 57 are interlocked and connected to the output gear 58 of the corresponding side clutch brake device 55 via the transmission gear 59 inside the transmission case 49.

  In other words, the engine 40 is deployed with its output shaft 41 oriented in the front-rear direction, and the transmission power is configured to extract the rotational power around the front-rear axis from the engine 40 from the rear of the engine 40. By arranging the case 49 and the hydrostatic continuously variable transmission 50 as described above, the transmission case 49 is placed at the front end of the traveling machine body 1 where the drive shafts 57 of the left and right crawler type traveling devices 7 are disposed. Since the transmission system in the transmission case 49 is configured as described above, the left and right side clutch brake devices 55 serving as final transmission devices for the left and right crawler type traveling devices 7 in the transmission case 49 are provided. , The rotational power about the left and right axis is output, and as a result, the drive shaft of each of the left and right crawler type traveling devices 7 is output. 7 and the corresponding output gear 58 of the side clutch brake device 55 can be connected to each other with a simple configuration through a single transmission gear 59. As a result, the left and right crawler type traveling devices can be connected. The transmission structure for 7 can be simplified.

  As shown in FIGS. 8, 9, 12, and 13, a left and right power take-off shaft 60 that outputs low-speed power from the gear-type transmission 48 is installed on the upper portion of the transmission case 49. The power from the shaft 60 is transmitted to the input shaft 18 of the cutting and conveying section 3 via the belt tension type cutting clutch 61 that switches the transmission state based on the forward and backward swinging operation of the cutting clutch lever 15. Thus, during the work travel in which the cutting and conveying unit 3 is driven, the driving speed of the cutting and conveying unit 3 is shifted in synchronization with the traveling shift by the hydrostatic continuously variable transmission 50, Good cutting and conveying can be performed according to the running speed.

  As described above, the input shaft 18 of the cutting and transporting unit 3 is disposed in the left-right orientation at the upper front end of the traveling machine body 1, and the transmission case 49 is located at the front end part of the traveling machine body 1 as described above. The input shaft 18 of the transport unit 3 and the left and right power take-out shaft 60 disposed at the upper part of the transmission case 49 are positioned relatively close to each other. The transmission connection between the case 49 and the power take-out shaft 60 is facilitated, and as a result, the transmission structure for the cutting and conveying unit 3 can be simplified.

  As shown in FIGS. 8, 9, and 12, the cutting and conveying unit 3 moves up and down by the forward / reverse operation of the lifting device 62 configured in a screw feed type. The elevating device 62 includes a front-rear-facing input shaft 63 and a drive shaft 64 supported by the traveling machine body 1, a chain-type transmission mechanism 65 that interlocks and connects the input shaft 63 and the drive shaft 64, and a universal joint 66 on the drive shaft 64. A screw shaft 67 interlocked with each other, and a cylindrical shaft 69 provided with a female screw 68 threadedly engaged with the screw shaft 67 at one end and the other end supported by the cutting frame 19 so as to be swingable up and down. The power from the engine 40 transmitted to the first relay shaft 52 to the input shaft 63 is provided on the input shaft 63 based on the swinging operation of the control lever 12 in the front-rear direction. Is transmitted via a belt tension type lifting clutch 70 that switches the transmission state to 62, and the screw shaft 67 is driven to rotate forward by the power thereof, so that the cylinder shaft 69 is screw-fed to the cutting and conveying unit 3 side and the cutting is performed. Ascend and swing the transport unit 3 A forward operating state to. The lead angle between the screw shaft 67 and the female screw 68 is set to a large angle that allows the screw shaft 67 to be driven in reverse rotation by the weight of the cutting and conveying device 3. By being driven in the reverse direction, the cylinder shaft 69 is screw-fed to the traveling machine body 1 side, and the reversal operation state in which the cutting and conveying unit 3 is lowered and swung is brought about.

  As described above, the power from the engine 40 transmitted to the first relay shaft 52 is distributed and supplied to the lifting device 62 via the lifting clutch 70, so that the lifting device 62 is connected to the lifting shaft 62 from the output shaft 41 of the engine 40. Compared with the case where a dedicated transmission system for the lifting device 62 is provided over the input shaft 63, the transmission structure for the lifting device 62 can be simplified.

  When the control lever 12 is located at the neutral position, the lift clutch 70 is in a cut-off state that interrupts transmission from the first relay shaft 52 to the lift device 62, and the control lever 12 is operated from the neutral position to the forward lowered position. In this case, the cut-off state is maintained, and only when the control lever 12 is operated from the neutral position to the rearward raised position, it is switched to the on-state transmitted from the first relay shaft 52 to the lifting device 62. In addition, as the cutting and conveying unit 3 reaches the upper limit position, the tension arm 71 is moved vertically to the traveling machine body 1 so that the cutting and conveying unit 3 is switched from the entering state in which the cutting and conveying unit 3 is lifted and swung to the cutting state. It is linked to the cutting frame 19 via a balance arm 72 supported so as to be able to swing the balance.

  When the control lever 12 is positioned at the neutral position or the raised position, the lifting clutch 70 is configured to permit the forward rotation of the driven pulley 73 that rotates integrally with the input shaft 63 of the lifting device 62 and prevent reverse rotation. When the control lever 12 is in the lowered position, the brake arm 74 that is separated from the driven pulley 73 and allows the forward / reverse rotation of the driven pulley 73 is provided.

  That is, when the control lever 12 is returned to the neutral position, the elevating clutch 70 is disengaged and the braking arm 74 is brought into contact, whereby the elevating device 62 is powered by the engine 40 of the screw shaft 67. Since the forward rotation driving by the lift clutch 70 is blocked by the lifting clutch 70 and the reverse rotation driving by the weight of the cutting and conveying device 3 is blocked by the braking arm 74, the cutting and conveying section 3 can be lifted and stopped. . When the control lever 12 is operated to the raised position, the elevating clutch 70 is engaged, and the braking arm 74 is brought into contact, whereby the elevating device 62 is driven by the power from the engine 40 of the screw shaft 67. Since the forward rotation operation is allowed in the forward operation state permitted by the elevating clutch 70 and the braking arm 74, the cutting and conveying section 3 can be swung up and down. When the cutting and conveying unit 3 reaches the upper limit position by the upward swing, the lifting and lowering clutch 70 is switched to the disengaged state by the balance arm 72, while the forward rotation drive by the power from the engine 40 of the screw shaft 67 is prevented. The braking arm 74 is maintained in the contact state, so that the reverse rotation driving due to the weight of the cutting and conveying device 3 of the screw shaft 67 is prevented, and thereby the lifting device 62 is in the operation stopped state. The cutting and conveying unit 3 can be automatically stopped at the position. Conversely, when the control lever 12 is operated to the lowered position, the lifting clutch 70 is disengaged and the braking arm 74 is separated, whereby the lifting device 62 is driven by the power from the engine 40 of the screw shaft 67. Since the forward rotation driving is prevented by the lifting clutch 70 and the reverse rotation driving by the weight of the cutting and conveying device 3 is permitted by the braking arm 74, the cutting and conveying portion 3 can be swung downward. .

  The lifting device 62 is configured to be a screw feed type in which the cutting and conveying unit 3 is swung up and down by forward rotation driving by the power from the engine 40 of the screw shaft 67 and reverse driving by the weight of the cutting and conveying device 3. When a hydraulic type that requires a pump, a hydraulic cylinder, or the like, an electric type that requires an electric motor, or while using the power from the engine 40, the screw shaft 67 is driven forward or backward with that power. As a result, the manufacturing cost and the maintenance cost can be reduced and the maintenance can be facilitated as compared with the case where a mechanical type that requires a forward / reverse switching mechanism for switching the rotation direction of the screw shaft 67 is used.

  As shown in FIGS. 1 to 3 and FIG. 12, the threshing device 4 is disposed on the left side of the engine 40, so that a mission case 49 and a hydrostatic continuously variable transmission 50 that are positioned in front of the threshing device 4 As described above, by being arranged on the front side of the fuselage rather than the rear end of the engine 40, it can be arranged closer to the front of the fuselage than the rear end of the engine 40. The threshing device 4 having a high processing capability including a long handling cylinder 25 and a swing sorting device 28 in the front-rear direction can be adopted while being short enough to be loaded on a carrier of a small transport vehicle such as a light truck, As a result, work efficiency and sorting accuracy can be improved.

  As shown in FIGS. 11 and 12, the threshing clutch 47 includes a rear end portion of the second relay shaft 75 in which the output shaft 41 of the engine 40 is disposed close to the left upper side of the first relay shaft 52 in a front-back orientation. The second relay shaft 75 is connected to the right end portion of the drive shaft 77 of the carp 27 via a pair of bevel gears 76, and the front end portion of the second relay shaft 75 is a belt tension type third transmission. It is linked to the front end portion of the drive shaft 79 of the handling cylinder 25 via a mechanism 78, and the drive shaft 77 of the carp 27 has a left end portion of the first screw 29 via a belt tension type fourth transmission mechanism 80. A driving shaft (not shown), a driving screw (not shown) of the second screw 31 and the second reduction mechanism 32, a driving shaft (not shown) of the feed chain 24, and the like are interlocked and connected.

  The threshing clutch 47 is configured to switch the transmission state from the engine 40 to the threshing device 4 based on the swinging operation of the threshing clutch lever 16 in the front-rear direction.

  As described above, the engine 40, the hydrostatic continuously variable transmission 50, the cutting and conveying unit 3, and the threshing device 4 are arranged and set, and the power transmission from the output shaft 41 of the engine 40 is configured. Is composed of a first transmission mechanism 46, a threshing clutch 47, a first relay shaft 52, a second transmission mechanism 53, and the like that distribute the oil to the hydrostatic continuously variable transmission 50, the cutting and conveying unit 3, and the threshing device 4. As a result, the transmission system can be simplified and the assembly performance can be improved.

  As shown in FIGS. 1 to 3, 5, 6, and 14, the traveling machine body 1 is provided with a column (an example of a fixing portion) 81 that extends upward between the threshing device 4 and the engine bonnet 9. A fuel tank 82 is connected to the upper end portion of the support column 81 so as to be positioned between the driver's seat 10 and the storage hopper 34. In other words, the space formed between the driver's seat 10 and the storage hopper 34 above the engine bonnet 9 is effectively used as the arrangement space for the fuel tank 82, so that the size of the combine as a whole can be reduced. . Further, since the position of the fuel tank 82 is increased, a feed pump can be eliminated, and the fuel supply structure can be simplified.

  As shown in FIG. 14, the fuel in the fuel tank 82 is supplied from the bottom of the fuel tank 82 to the fuel filter 84 disposed on the right side of the engine 40 via the first supply pipe 83. After being filtered, it is supplied to the fuel injection pump 86 via the second supply pipe 85, and after being pressurized by the fuel injection pump 86, it is pumped to each fuel injection nozzle 88 via each injection pipe 87, The fuel is injected from each fuel injection nozzle 88 into each fuel chamber. Then, surplus fuel is reduced from each fuel injection nozzle 88 into the fuel tank 82 via the reduction pipe 89.

  An air vent portion 90 is formed at the upper portion of the fuel filter 84 to remove the air accumulated therein, and the air vent portion 90 is connected to a reduction pipe 89 via an air vent pipe 91. Therefore, air accumulated in the fuel filter 84 at the time of running out of fuel or the like is discharged from the air vent 90 to the fuel tank 82 through the air vent 91 and the reduction pipe 89, and the air vent of the fuel tank 82 (not shown). To the outside of the aircraft.

  That is, since the fuel reduction path from the fuel injection nozzle 88 and the air vent path from the fuel filter 84 are joined and connected to the fuel tank 82, the fuel reduction path from the fuel injection nozzle 88 and the air vent path from the fuel filter 84 are connected. Can be simplified as compared with the case where these are formed independently and connected to the fuel tank 82.

  Further, when the fuel return path from the fuel injection nozzle 88 and the air vent path from the fuel filter 84 are independently formed and connected to the fuel tank 82, the fuel filter 84 is clogged when clogged. As a result, the so-called air biting in which air is supplied to the fuel injection pump 86 is likely to cause a problem that the engine 40 is stopped. However, in the fuel supply structure in this embodiment, the fuel reduction path and the air vent path are joined together. Therefore, when the fuel filter 84 is clogged, surplus fuel from the fuel injection nozzle 88 is supplied to the fuel injection pump 86, and as a result, it is difficult to stop the engine due to air engagement.

  As shown in FIG. 15, instead of the fuel supply structure described above, a reduction pipe 89 that forms a fuel reduction path from the fuel injection nozzle 88 is connected to the air vent 90 of the fuel filter 84, and air is vented from the fuel filter 84. By connecting the air vent pipe 91 forming the path to the fuel tank 82, the air accumulated in the fuel filter 84 at the time of running out of fuel is discharged from the air vent portion 90 into the fuel tank 82 via the air vent pipe 91. When the fuel filter 84 is discharged from the air vent (not shown) of the fuel tank 82 and the fuel filter 84 is clogged, surplus fuel from the fuel injection nozzle 88 is supplied to the fuel injection pump 86. You may do it.

  As shown in FIGS. 4, 5, 7, 14, and 15, the driver's seat 10 is provided with a pair of left and right brackets 92 at the bottom front end, and these brackets 92 are located at the upper front end of the engine bonnet 9. The support member 93 is connected to the support member 93 via a left and right support shaft 94 so as to be swingable back and forth around the axis.

  That is, the driver's seat 10 is configured to be changeable between a sitting posture located above the engine bonnet 9 and a falling posture that is turned down toward the front front panel 13, and by switching to the falling posture, Accumulation of dust and the like on the seating surface when not in use can be avoided, the driver's seat 10 can be prevented from interfering when the fuel tank 82 is refueled, and the replenishment tank can be installed when refueling. When used, the engine bonnet 9 can be used as a temporary storage base for the replenishment tank, and as a result, it becomes easier to refuel the fuel tank 82 disposed above the engine bonnet 9.

Further, as shown in FIG. 16, the bottom front end portion of the driver seat 10 is connected to the left and right support portions 93A, 93A extending upward from the support member 93 via the left and right support shafts 94, and the driver seat. 10, the left end of the front plate portion 93B of the support member 93 by connecting via the connecting pin 95 of the front and rear direction to the engine hood 9, and vertically swingably in the axial about its coupling pin 95, also, A hook 97 that can be engaged with an engagement pin 96 projecting forward from the upper front end of the engine bonnet 9 is provided at the right end portion of the support member 93 around the shaft center via a longitudinally supporting shaft 98. In addition to the above-described seating posture and overturning posture, the lever guide 17 on the left side is provided with a swinging operation and a spring 99 fitted on the support shaft 98. Appears in a lying posture If it is configured to be changeable, when the fuel tank 82 is refueled, the driver's seat 10 is prevented from being obstructed by switching the driver's seat 10 to its lying posture, and the engine bonnet. 9 can be used as a temporary storage base for the replenishment tank, and fuel can be replenished from a relatively high position where the vehicle enters the boarding operation unit 2. As a result, the fuel tank 82 provided above the engine bonnet 9 can be refueled. Refueling becomes easier.

  By the way, in a combine, in order to prevent running out of fuel in the middle of work, work may be performed with a supply tank loaded.

  Therefore, as shown in FIGS. 17 and 18, a space for loading the replenishment tank 100 is secured at a location behind the driver seat 10 in the engine bonnet 9 and a column 81 for supporting the fuel tank 82 is provided in the space. A bracket 101 equipped on the support shaft 102, a support shaft 102 supported by the bracket 101 so as to be rotatable and slidable, and a support plate 103 provided on an extending portion extending forward from the bracket 101 of the support shaft 102, In addition, the locking pin 104 provided on the support shaft 102 is placed on the engine bonnet 9 by a spring 106 that urges the support shaft 102 in a direction to engage with the pair of locking holes 105 formed in the bracket 101. A receiving posture for receiving and supporting the left side surface of the replenishing tank 100, and placing and supporting the replenishing tank 100 at the same height as the fuel tank 82. A support member 107 configured to be switchable to a possible mounting posture is provided, and when the vehicle is traveling, the support member 107 is switched to a receiving posture to receive and support the replenishment tank 100, thereby The replenishment tank 100 can be prevented from falling due to an inclination or the like, and when the fuel is replenished, the support member 107 is switched to the mounting posture and the replenishment tank 100 is placed and supported, so that the replenishment tank 100 can move to the fuel tank 82. It may be possible to easily refuel.

  In particular, since the replenishment tank 100 can be positioned at the same height as the fuel tank 82, siphon-type replenishment is possible, and fuel replenishment from the replenishment tank 100 to the fuel tank 82 can be further facilitated.

  As shown in FIGS. 1 to 7 and 11, the engine bonnet 9 includes a front wall 110 and a right wall 111 formed in a duct shape including air passages 108 and 109, a ceiling wall 112 on which the driver's seat 10 is installed, and A large number of left and right slit-like exhaust ports 113 are formed of a rear wall 114 formed so as to extend over substantially the whole.

  The front wall 110 includes a first plate 115 bent to have a front surface, an upper surface, and a lower surface, a second plate 116 that forms a back surface, a first dust net 117 that forms a left side surface, A second dust net 118 that covers an opening formed from the lower end portion of the front surface of the first plate 115 to the front and rear intermediate portions of the lower surface is joined, and a communication port 119 to the right wall 111 is provided at the right end thereof. A soft first dust-proof seal 120 that fills the gap with the right side wall 111 is attached to the right end so as to surround the communication port 119. The second plate body 116 is formed with a first supply port 121 for supplying cooling outside air to the radiator 43 and a second supply port 122 for supplying outside air to the air cleaner 44, and is soft enough to fill a gap with the radiator 43. The second dust-proof seal 123 surrounds the first supply port 120, and the soft third dust-proof seal 125 that fills the gap between the air cleaner 44 and the intake pipe 124 surrounds the second supply port 122, respectively. It is stuck.

  The right side wall 111 is formed to bulge so as to include a first plate body 126 that forms the left side surface thereof, and a right side surface and a peripheral surface that extends to the left from the right side surface beyond the left side surface. The formed second plate 127 and a dustproof net 128 that covers the opening formed in the second plate 127 are joined to each other, and a communication port 129 with the front wall 110 is formed at the front end of the first plate 126. Is formed.

  That is, the engine bonnet 9 has a first dust net 117 on the left side of the front wall that serves as an outside air introduction portion and a second dust net 118 at the lower end of the front wall, due to the suction action of the cooling fan 42 disposed behind the radiator 43. The outside air is introduced from each of the dust-proof nets 128 on the right outer side of the right side wall, and the outside air from the first dust-proof net 117 and the outside air from the second dust-proof net 118 pass through the air passage 108 of the front wall 110 or The outside air from the dust screen 128 passes from the first supply port 121 to the radiator 43 and the second supply port 122 to the air cleaner 44 via the air passage 109 of the right side wall 111 and the air passage 108 of the front wall 110. The outside air that has been supplied from each of the air and passed through the radiator 43 is made to flow around the engine 40, the muffler 45, etc., and then discharged from the plurality of exhaust ports 113 of the rear wall 114 to the outside of the machine.

  As a result, a large amount of outside air from the left and right and below the front wall 110 can be uniformly supplied to the entire radiator 43 as cooling outside air, and the cooling outside air after passing through the radiator is supplied to the engine 40, the muffler 45, and the like. After flowing to the surroundings, it can be quickly discharged to the rear of the boarding operation unit 2, so that the cooling efficiency can be improved and the exhaust gas flows toward the boarding operation unit 2 to make the driver uncomfortable. Deterioration of work environment such as giving

  In particular, by providing a dust-proof net 128 as an outside air introduction portion on the right side surface of the right side wall 111 having a larger area than the original area, a large area can be secured as an outside air introduction area in the right side wall 111 and more outside air can be introduced. In addition, since the outside air introduction area is large, even when dust contained in the outside air adheres to the dustproof net 128 when the outside air is introduced, it is difficult for the inconvenience that the outside air is not introduced due to the adhesion. Moreover, since the right side wall 111 is located on the already harvested side of the fuselage, and the dustproof net 128 as the outside air introduction portion faces the already harvested side, the outside air introduced from the dustproof net 128 is The content rate of dust generated sometimes is small, and when the outside air is introduced, the dust contained in the outside air adheres to the dust-proof net 128, and the inconvenience that hinders the introduction of the outside air hardly occurs.

  That is, it is possible to introduce more outside air as cooling outside air while reducing the number of work interruptions due to clogging of the outside air introduction section, thereby improving both work efficiency and cooling performance.

  Further, the engine noise generated in the engine room 8 is provided by providing the dust screens 117, 118, and 128 serving as the outside air introduction portions on the left side surface and the lower end portion of the front wall 110 and the right outside surface of the right wall 111. Can effectively prevent the leaked engine sound and the like from causing discomfort to the driver of the boarding operation unit 2, and as a result, the work environment caused by the sound leakage Deterioration can be avoided.

  Further, by forming a large number of slit-like exhaust ports 113 that are horizontally oriented so as to exhaust the cooling air, the flow rate of the cooling air discharged from each of the exhaust ports 113 is effectively reduced. Accordingly, it can be avoided that an operator working in the work space 36 behind the vehicle feels uncomfortable due to the cooling outside air from each exhaust port 113.

  As shown in FIG. 7, a shielding plate 130 is provided between the engine 40 and the hydrostatic continuously variable transmission 50 to prevent the flow of outside air that has passed through the radiator 43 to the hydrostatic continuously variable transmission 50. Thus, it is possible to avoid the temperature increase outside air from the engine room 8 from adversely affecting the hydrostatic continuously variable transmission 50.

  As shown in FIGS. 7 and 12, the hydrostatic continuously variable transmission 50 is cooled by cooling air generated by a cooling fan 131 disposed behind the hydrostatic continuously variable transmission 50.

  As shown in FIGS. 3 to 7, 11 and 19 to 22, in the engine bonnet 9, the right side wall 111 has a pair of front and rear provided at the bottom so that the right side wall 111 can swing left and right with respect to the traveling machine body 1. The connecting piece 132 is connected to the traveling machine body 1 via a corresponding front and rear connecting pin 133, and the ceiling wall 112 and the rear wall 114 are connected to the right side wall 111 so as to swing together. Left-right swinging is prevented by a buckle-type locking device 137 including a locking ring 135 having an operation piece 134 provided at the left end portion of the ceiling wall 112 and a hook 136 standing upright at the right end portion of the lever guide 17. It is switched between a state and an allowed state. A concave portion 139 is formed at the left rear end of the ceiling wall 112 to avoid interference with the cover 138 that covers the exposed portion of the third transmission mechanism 78.

  On the other hand, the pair of left and right connecting pieces 140 and 141 provided on the bottom of the front wall 110 is supported by the pair of left and right sides provided in the traveling body 1 so that the front wall 110 can swing back and forth with respect to the traveling body 1. The upper ends of the shafts 142 and 143 are connected to the radiator 43 via a pair of left and right knob-attached bolts 144. Of the left and right connecting pieces 140, 141, the left connecting piece 140 has a through hole 145 through which the left support shaft 142 is inserted, and the right connecting piece 141 is engaged with the right support shaft 143 from above. It is formed in a downward U-shape that enables the combination. The left and right support shafts 142 and 143 are connected to the travel aircraft body 1 so that the left and right support shafts 142 and 143 are cantilevered by the travel aircraft body 1, and the left support shaft 142 is formed shorter than the right support shaft 143. The right support shaft 143 is provided with a beta pin 146 that prevents the front wall 110 from sliding to the left with respect to them.

  From the above configuration, when the lock 137 is released, the engine bonnet 9 is displaced outwardly from the working posture covering the engine 40, the radiator 43, etc. with the front wall 110 left, leaving the engine 40 Since the bag can be changed to a maintenance posture that opens the radiator 43 and the radiator 43, and the bagging device 5 having a work space 36 formed on the lower side is provided at the rear thereof, the engine bonnet is provided. 9 is changed from a working posture to a maintenance posture, so that the power from the output shaft 41 of the engine 40, which is centrally arranged on the rear side of the engine 40, the radiator 43, and the engine 40, is hydrostatically variable. 50, the upper part of the distribution transmission system distributed to the reaping and conveying unit 3 and the threshing device 4, the right side, and the rear can be greatly opened. The maintenance of these, can be easily performed from the back of the right outside and the engine of the aircraft.

  Further, as shown in FIG. 23, a screw transporting type grain discharging device 147 is provided behind the engine bonnet 9 instead of the bagging device 5, and the axis of the vertical screw 148 in the grain discharging device 147 is provided. Swinging around the storage position for storing single-grained grains conveyed by the lifting conveyor 30 adjacent to the threshing device 4 and the maintenance position for opening the rear of the engine bonnet 9 apart from the threshing device 4 In the case where the grain tank 149 configured to be dynamically displaceable is adopted, the engine bonnet 9 can be moved to the maintenance position and the kernel tank 149 can be displaced to the maintenance position. 40, the radiator 43, and the distribution transmission system centrally arranged on the rear side of the engine 40. It is possible to hear open, the maintenance of them, can be easily performed from the back of the right outside and the engine of the aircraft.

  In addition, since the posture change of the engine bonnet 9 is performed with the front wall 110 left, the change between the front wall 110 and the radiator 43 that occurs when the posture of the engine bonnet 9 including the front wall 110 is simply changed. The second dust-proof seal 123 interposed between them and the third dust-proof seal 125 interposed between the front wall 110 and the intake pipe 123 of the air cleaner 44 are brought into sliding contact with the radiator 43 and the intake pipe 123. It is possible to avoid damage caused by dripping or the like, and reliably prevent dust from flowing in from the gap between the front wall 110 and the radiator 43 or the gap between the front wall 110 and the air intake pipe 123 of the air cleaner 44 over a long period of time. .

  On the other hand, if the connection between the front wall 110 and the radiator 43 by the bolts 144 with the left and right knobs is released, the beta pin 146 is removed from the right support shaft 142, and the sliding displacement to the left of the front wall 110 is allowed. The attitude change between the working attitude and the maintenance attitude of the engine bonnet 9 is achieved by sliding the front wall 110 to the left to a position where the interference with the peripheral surface of the second plate 127 on the right side wall 111 can be avoided. Regardless of whether the front wall 110 is separated from the radiator 43 or the intake pipe 123 of the air cleaner 44, the front wall 110 can be changed to a forward tilted attitude or removed from the traveling machine 1, and the radiator 43 and the air cleaner 44 can be removed. Maintenance from the front becomes easier.

  In particular, in the working posture of the engine bonnet 9, the first dustproof seal 120 interposed between the right side wall 111 and the right side wall 111 can be separated from the right side wall 111 by sliding the front wall 110 to the left. When the posture of the front wall 110 is changed or removed, the first dustproof seal 120 can be prevented from being damaged due to the sliding contact with the right side wall 111 and the like. The possibility of dust flowing in from the gap with the wall 111 can be reliably prevented over a long period of time.

  In addition, the front wall 110 is prevented from falling forward by the first plate body 115 coming into contact with the boarding step 11.

  Although illustration is omitted, instead of the above configuration, in the working posture of the engine bonnet 9, the peripheral surface of the second plate 127 on the right side wall 111 is the front regardless of the sliding displacement of the front wall 110 to the left. It may be configured to interfere with the wall 110 so that the posture of the front wall 110 can be changed and attached only when the posture of the engine bonnet 9 is changed to the maintenance posture. The posture of the front wall 110 may be changed within a range until the peripheral surface of the second plate 127 on the right side wall 111 interferes with the front wall 110.

  As shown in FIGS. 24 to 29, instead of the above-described configuration, the engine bonnet 9 can be changed to the working posture and the maintenance posture when the entire engine bonnet 9 including the front wall 110 can be changed. Of the pair of left and right connecting pieces 140 and 141 provided at the bottom of the wall 110, the right connecting piece 141 is supported by a support shaft 150 extending leftward from the first plate 126 of the right wall 111. The front wall 110 is connected to the radiator 43 with the left and right knob bolts 144 with the ceiling wall 112 interposed, and the left connection piece 140 of the left and right connection pieces 140 and 141 is connected to the left side. Is formed in a downward U-shape that allows engagement with the support shaft 142 from above, and a through hole 151 through which the support shaft 150 of the right side wall 111 is inserted is formed in the right connection piece 141, If a beta pin 146 that suppresses the sliding displacement of the front wall 110 to the left is attached to the support shaft 150 of the wall 111, the front wall 110 is connected to the radiator 43 by the bolts 144 with knobs on the left and right. When the lock 137 is released and the lock 137 is released, the entire engine bonnet 9 including the front wall 110 is allowed to swing left and right, and the front wall 110 is independently swung back and forth. The second dust-proof seal 123 interposed between the front wall 110 and the radiator 43 moves away from the radiator 43 in accordance with the initial operation when changing the posture to the maintenance posture or from the stage before the posture change. The posture of the third dust-proof seal 125 interposed between the air cleaner 44 and the intake pipe 123 can be changed to a forward tilted attitude away from the intake pipe 123. As a result, it is possible to change the posture of the entire engine bonnet 9 without causing damage due to the second dustproof seal 123 and the third dustproof seal 125 being brought into sliding contact with the radiator 43 or the intake pipe 123. When the posture is changed to the maintenance posture, the surroundings of the engine 40 and the radiator 43 can be greatly opened.

  When the front wall 110 swings back and forth, the first dust-proof seal 120 interposed between the front wall 110 and the right side wall 111 is pressed against the right side wall 111 when the lock 137 is released. Since this is released, it is possible to avoid damage due to sag due to sliding contact with the right side wall 111 of the first dustproof seal 120.

  Furthermore, the front wall 110 is allowed to slide to the left by removing the beta pin 146 from the support shaft 150 of the right side wall 111 and releasing the connection with the ceiling wall 112 by the bolts 144 with the left and right knobs. Thus, it can be removed from the engine bonnet 9, so that the area around the radiator 43 and the air cleaner 44 can be opened larger.

  That is, there is a possibility that dust may flow in from the gap between the front wall 110 and the radiator 43, the gap between the front wall 110 and the intake pipe 123 of the air cleaner 44, and the gap between the front wall 110 and the right side wall 111 for a long time. While being able to prevent reliably, the maintainability with respect to the engine 40, the radiator 43, the air cleaner 44, etc. can be improved further.

  The front wall 110 is prevented from falling forward because the first plate 115 abuts against the peripheral surface of the second plate 127 in the right side wall 111.

  By the way, although not shown, instead of the structure in which the front wall 110 is fixed by the left and right bolts 144 with knobs, the same thing as the buckle type locking device 137 provided over the well wall 112 and the lever guide 17 is used as the ceiling wall. If it is provided over the front wall 110 and the front wall 110, the front wall 110 can be fixed and released more easily, and thereby the operation for changing the posture of the engine bonnet 9 and attaching / detaching the front wall 110 can be performed. Can improve the performance.

  Incidentally, as shown in FIG. 3 and FIG. 6, the ceiling wall 112 is formed with a recess 139 for avoiding interference with the cover 138 at the left rear end thereof, so that when the posture of the engine bonnet 9 is changed, The possibility of interfering with the fuel tank 82 disposed above the engine bonnet 9 can be avoided, so that the arrangement position of the fuel tank 82 becomes too high in order to avoid interference with the engine bonnet 9. Due to this, it is possible to avoid the occurrence of inconveniences such as difficulty in refueling the fuel tank 82 without forming a dedicated recess for avoiding interference with the fuel tank 82.

  Further, as described above, since the fuel tank 82 is supported on the support column 81 standing on the traveling machine body 1, it is not necessary to mount the fuel tank 82 on the engine bonnet 9, thereby allowing the engine bonnet 9 to be fueled. The reinforcement structure for the engine bonnet 9 required when the tank 82 is mounted and installed can be eliminated, and the fuel tank 82 that is generated when the fuel tank 82 is mounted and installed on the engine bonnet 9 is connected to the engine bonnet 9. Complicating the piping structure for the fuel tank 82 by changing the posture integrally can be avoided, so that the configuration can be simplified and the operability when changing the posture of the engine bonnet 9 is advantageous.

  As shown in FIG. 8, the air cylinder 152 that assists the ascending and swinging of the cutting and conveying unit 3 and prevents the sudden and downward swinging of the cutting and conveying unit 3 across the traveling machine body 1 and the cutting and conveying unit 3. Is constructed, and the lifting and lowering operation of the cutting and conveying unit 3 can be comfortably performed.
