A traveling device 2 having an endless track crawler track is provided on the left and right lower sides, and the traveling device 2 is driven from the engine 3 mounted on the right side of the vehicle body via a mission so that it can self-propel. Yes.
[0007]
4 is a threshing machine, which is mounted on the left side of the vehicle body 1 so that the axis of the handling chamber in which the handling cylinder is pivoted in the interior is directed in the front-rear direction, and is opened on the left side surface of the handling chamber in the front-rear direction. A threshing supply chain 5 for holding grain is provided along the outside of the mouth, and the chain 5 is used to hold and transfer the grain side of the grain, and the tip side of the grain is transferred from the front side to the rear side in the handling chamber. The threshing is done by rotating the barrel. 6 is a supply port for the cereals opened in the front side wall surface of the threshing machine 4.
[0008]
A Glen tank 7 is provided on the left body 1 of the threshing machine 4 and accommodates the grains processed and taken out by the threshing machine 4. Reference numeral 8 denotes a cutter device.
Reference numeral 9 denotes a steering seat, which is disposed at the upper part of the engine, and a steering operation frame 10 on the front side and the left side thereof is provided with a steering member such as a steering lever and a meter. Reference numeral 11 denotes a cutting and conveying device, which is a front vertical conveying device that collects and vertically conveys the harvested cereal grains collected by the weeding device 12, the pulling device 13, the cutting blade device 14, the scraping device 15, and the left and right scraping devices 15. While engaging and transferring the chain 16, the stock holding grip chain 17 that takes over the cereals being transferred from the front vertical transfer chain 16 and transfers it to the upper rear side, and the tip side of the cereals that are being transferred to the upper rear side It is configured to be equipped with a tip transport device 18 or the like that changes the posture into a lying state as the tip side falls to the right side as it is moved backward.
[0009]
The stock transport chain 17 is a driven sprocket 21 attached to the drive shaft 20 of the transmission vertical cylinder case 19a on the frame 19 side of the cutting and transporting apparatus 11 and is positioned on the rear upper side and separated from the left and right. It is wound around the sprockets 22 and 23. The mounting frame 24 for pivotally supporting each sprocket for winding the stock transport chain 17 is driven by a servo motor M1, and an electric cylinder 25 is used to center the axis of the drive shaft 20. It is possible to adjust the rotation. That is, the grain holding and transporting portion (A) is rotated left and right in a plan view. Reference numeral 26 denotes a bowl which is configured to be held against the grain holding and conveying unit (I) of the chain 17.
[0010]
Depth detection device 27 is configured to detect the position of the tip of the corn straw supplied to the supply port 6 of the threshing machine 4, and is usually an actuator that hangs at a predetermined interval above the entrance of the supply port 6. The switches SW1, SW2 and SW3 connected to the head are provided to detect which actuator is touching the head portion of the cereal, and the switch SW1 is turned on by the contact of the actuator from the ear tip side. When the switch SW3 connected to the actuator from the stockholder side becomes “OFF”, it is determined that the handle is shallow, and the switch SW2 connected to the middle actuator on the left and right is “ The detection apparatus is set to have the optimum handling depth when the state of repeating “ON” and “OFF” is repeated.
[0011]
Then, the servo motor M1 is driven and controlled by the detection signal of the handling depth detecting device 27, and the mounting frame 24 of the stock transport chain 17 is rotated, so that the stock of the cereal meal being transported 1st handling depth automatic adjustment means A which adjusts automatically the position which delivers to the supply chain 5 by the threshing machine 4 side is provided.
[0012]
On the other hand, separately from the first handling depth automatic adjusting means, the holding transfer direction by the stock transport chain 17 is changed, and the stock side of the cereal being transferred is opened in the direction away from the threshing supply chain 5. Second handling depth automatic adjusting means B in a form that can be inherited is provided. In a specific embodiment, the spindle 28 of the driven sprocket 23 is mounted on a frame 24 via a swing arm 29, and this arm 29 is driven by a servo motor M2. Adjust the rotation at -30 and move away from the direction of the arrow (b) approaching the supply port 6 so that the rice cake holder can be transferred in the direction of the arrow (c) on the right side faster. Yes.
[0013]
Further, in the control by the first handling depth automatic adjusting means A, when the handling depth is controlled to the maximum handling side at the time of ultra-short dredging, the position limit in the right direction of the stock base end is detected. The servo motor M1 is stopped by the detector 31 to limit the deep handling side control, and the stock is prevented from being held by the threshing supply chain 5.
[0014]
When the second handling depth automatic adjusting means B detects that the detector 31 has reached the deep handling side limit control, the tip of the tip side is ignored and the switch SW3 for determining the shallow handling is ignored. It is configured to control to the deep handling side until it becomes “ON”. In other words, the second automatic handling depth adjusting means is configured so that the threshing supply chain 5 determines the position of the tip-side limit dimension from the end of the stock and holds and transfers it during normal operation. Ignoring the guarantee of ensuring, the ultra-short cereal cereals that cannot be held are supplied as they are into the handling chamber of the threshing machine 4 without being held, thereby preventing unhandling.
[0015]
In addition, although the 2nd handling depth automatic adjustment means B of the above example was set as the structure which changes and adjusts the direction of a conveyance transfer direction, the threshing machine by the side of the threshing machine 4 as shown in FIG.3 and FIG.4 A deep handling auxiliary feeding device 33 is provided that engages the cereal cake with the cradle 32 provided on the front side of the supply port 6 and transfers it to the inner side of the supply port 6, and this auxiliary feeding device 33 acts on the cereal cake. Thus, it is possible to switch between a state in which deep handling is promoted and a state in which it is retracted under the receiving base 32 and does not act. This switching is performed by an electric cylinder 34 by a servo motor M3. In addition, various methods are conceivable, but in any case, when the deep handling side control by the first handling depth adjusting means A is in a state where the culm length of the cereal is extremely short and left unhandled, Even if the handling depth adjusting means B works and the holding by the supply chain 5 on the threshing machine 4 side becomes uncertain, priority is given to prevention of unhandled residue, and a further deep handling state is achieved.
[0016]
The operation of the above example will be described. When harvesting rice and wheat to be harvested in the field, the harvesting device 12 causes the falling cereal while the cereals are separated by the weeding device 12 while the combine is self-propelled. 13, and then the stock is cut by the cutting blade device 14. Then, the cereal after cutting is scraped toward the left and right center by the scraping device 15, and is held by the front vertical conveying chain 16 and its heel and transferred to the rear upper side.
[0017]
After that, the stock holder is taken over by the stock holding chain 17 and its hook 26, and further transferred rearward and upward. In addition, at this time, the tip side wing is locked by the engagement lug of the tip tip transport device 18 and transferred upward, and at the same time, the tip side is gradually tilted toward the right side and the cereals are laid down side by side. The posture is changed to a state close to a substantially horizontal plane on the culm transfer terminal side.
[0018]
Then, the stocker side of the cereal that has reached this transfer terminal part is inherited by the supply chain 5 on the threshing machine 4 side, and the stocker part of the cereal is directly on the left outer side of the threshing machine 4 It is transported backward along the part. Therefore, the tip side is supplied into the handling chamber from the supply port 6 that opens to the front side of the threshing machine 4, and is threshed and sorted by the rotation of the handling cylinder, and the grain is stored in the Glen tank 7. On the other hand, the sawdust is discharged from a waste dust port opened at the rear of the threshing machine 4, and the waste is transferred rearward by the supply chain 5 and discharged to the field as it is or cut by a cutter or the like and discharged. .
[0019]
The grain pod supplied to the supply port 6 detects whether or not the tip side is at an appropriate position for threshing by the handling depth detection device 27. That is, when the actuator that hangs downward detects which position the tip passage position is on the left and right, and when the switch SW1 connected to the actuator detects the cereal, it is in a deep handling state. Then, a signal is generated and the servo motor M1 is operated to cause the piston 25a of the electric cylinder 25 to protrude, and the frame 24 on the stock transport chain 17 side is rotated in the direction of the arrow (d) in plan view. Move to control to the shallow handling side. On the contrary, when the switch SW3 connected to the actuator is turned off without passing through the cereal, it is determined that it is in the shallow handling state, and a signal is output, and the servo motor M1 is operated to operate the electric cylinder. The 25 pistons 25a are retracted, and the frame 24 on the stock transport chain 17 side is rotated in the direction opposite to the arrow (d) in the plan view and controlled to the deep handling side. Control is always performed while the switches SW3 and SW2 are in the on state, or at least the switch SW3 is in the on state.
[0020]
However, in order to maintain the switch SW3 in the ON state, a condition that ignores the premise that the cereal stockholder side is handed over to the supply chain 5 is necessary. That is, in the case of an ultra-short blade, in order for the tip to contact the leftmost actuator to turn on the switch SW3, it is necessary to be prepared to be held by the supply chain 5. Therefore, in general, a detector 31 for detecting whether or not a stock is present is configured in order to transfer the stock chain 5 while firmly holding it in the supply chain 5. When the passage is no longer detected, the operation control by the electric cylinder 25 of the stock transport chain 17 is immediately stopped, and the stock side is always held and transferred by the supply chain 5 with some margin.
[0021]
However, in the above-described ultrashort culm, the tip side is transported in a state where it does not enter the handling chamber sufficiently, and unhandled parts are generated without contacting the teeth handled by the handling cylinder. In such a case, the switch SW3 is turned off without the tip coming into contact with the leftmost actuator from the idea that even if cereals are slightly dragged into the handling chamber, it is better to be unable to harvest due to unhandling. And when the automatic control of the 1st handling depth automatic adjustment apparatus A will be in a stop state by the detector 31, the 2nd handling depth automatic adjustment means B will act | operate and it will be set to the deep handling side.
[0022]
That is, the electric motor 30 is actuated by the servo motor M2 to rotate the sprocket 23 inward via the swing arm 29, and the cereals being transferred are moved from the direction of the arrow (b) to the arrow (c). ) Change direction. Therefore, the cereals are transferred further to the left side from the previous transfer direction and eventually become deeply handled. In this way, when the deep handling side control by the first automatic handling depth adjustment device A is not performed, the second handling depth automatic adjustment control can make the handling state slightly deeper, Prevention can be achieved.
[0023]
The configuration of the scraping device 15 of the cutting and conveying device 11 will be described in detail. The scraping device 15 is used for weeding the grain straws in the field, and then scraping and gathering the ones that have been raised in advance by the pulling device 13, and the clogging tends to occur at the time of the scraping. It is a department that often causes problems. For this reason, it is desired to remove the clogged rice cake easily when the clogging is prevented in advance or when the clogging occurs. I couldn't find it. Therefore, the following means can be considered.
[0024]
As shown in FIG. 5, 41, 42, 43, 44, 45, and 46 are arranged on the frame 19 side of the cutting and conveying device 11 so as to arrange a plurality of grain chopping gears arranged side by side in the horizontal direction in a plan view. Bearings are made via shafts 41a, 42a, 43a, 44a, 45a, 46a, and the gears 41, 46 at the left and right ends and the middle gear 44 at the left and right ends are supported by the front longitudinal conveying chains 16a, 16b, 16c on the support shafts of these gears. It is configured to be driven by integral sprockets 47, 48, and 49. In addition, cylinders 50, 51, 52, 53, 54, and 55 cover the shafts on the upper surface sides of the respective gears 41 to 46 so that the cereals are not entangled with the respective support shafts. Configured. Further, pulleys 56, 57, 58, 59, 60, 61 fixed to the support shafts are provided on the upper portions of these cylindrical bodies, and the free end side of the cover body 62 that is rotatable on the support shafts. A belt 63 with a lagging lug is wound around driven pulleys 56a, 57a, 58a, 59a, 60a, 61a attached to a support shaft provided in FIG. The free end side of each cover body 62 is attached to the frame 19 side via an interchangeable component so as to move freely in the horizontal direction.
[0025]
The driven gear 42 meshing with the driving gear 41, the driven gear 43 meshing with the driving gear 44, and the driven gear 45 meshing with the driving gear 46 are all the same or meshed among the scraping gears configured in this way. One set of gears 43, which are positioned in the vertical plane where they cannot be disengaged and mesh with the drive gear 44 on the central side, are removed from the other gears in the vertical direction. The gears arranged on the left and right sides are not positioned in the same plane. This means that each driven gear 42, 43, 45 can escape to the opposite side with respect to the drive gear 41, 44, 46 meshing therewith. As an example of the escaping movement configuration, as shown in FIG. 6 and FIG. 7, a metal that rotatably receives a support shaft on a mounting side fixing frame 64 attached to the frame 19 side of the cutting and conveying apparatus 11. An integral supporting frame 65 is movably provided in the part and is configured to be set by a fixing pin 66. In this case, if the pin 66 is removed and the driven gear is disengaged from the drive gear, the cereals clogged in the meshed portion can be easily removed. As another example, if the set configuration by the pin 66 is stopped and the driven gear is supported by the spring 67 by the spring 67 as shown in FIG. Since it escapes against the spring 67, no clogging occurs, and even if clogging occurs, the clogged culm can be removed easily.
