[0012]
The configuration of the blower 7 and the Glen tank 5 will be specifically described.
The blower 7 is provided in a space between the operation unit 6 and the glen tank 5 and has a configuration in which an air suction port 7a and a discharge port 7b are provided. In addition, a grain feeding device 15 is provided in the lower part of the Glen tank 5 and is configured to be rotationally driven by a motor 13 and a chain 14. The grain feeding device 15 is provided with a plurality of blades 15a. The discharge port 7b of the blower 7 and the lower part of the grain feeding device 15 are connected by a pipe 16, and the other side (lower side in the grain conveying direction) of the lower part of the grain feeding device 15 is also connected to the pipe 17. Are connected to each other and are constituted by a single pipe 17 up to the vicinity of the grain outlet 8 a of the grain outlet auger 8. Plates 5b and 5c are provided at the front and rear of the Glen tank 5, respectively. The front plate 5 b is integrated with the blower 7 side, and the rear plate 5 c is integrated with the glen tank 5.
[0013]
The pipe 16 connecting the discharge port 7b of the blower 7 and the lower portion of the grain feeding device 15 is configured with flexibility, but may be configured with a steel pipe. Moreover, the pipe 16 which connects between the lower part of the said grain delivery apparatus 15 and the grain discharge port 8a of the grain discharge auger 8 is comprised by flexibility. The pipe 16 is configured to pass through a vertical steel pipe 19 that can be rotated in the left-right direction by a motor 18 and a horizontal steel pipe 21 that can be moved up and down by a hydraulic cylinder 20.
[0014]
A gear 19a is fixed to the vertical steel pipe 19, and meshes with a pinion 18a of a motor 18 fixed on the machine body side. In addition, a hydraulic cylinder 20 for raising and lowering the horizontal steel pipe 21 is provided between the vertical steel pipe 19 and the horizontal steel pipe 21. Next, the drive configuration of the blower 7 will be described with reference to FIG.
[0015]
FIG. 5 shows a plan view. A pulley 2c is fixedly provided on the output shaft 2b of the engine 2a placed below the operation unit 6. A belt 23 is wound around the pulley 2c between a pulley 25 fixed to the input shaft 24a of the counter case 24 at the rear. A pulley 24c is integrally formed with the output shaft 24b of the counter case 24 by casting.
[0016]
A belt 26 is wound around the pulley 24c between the pulley 28 of the input shaft 27a of the rear bevel case 27, and a belt tension clutch 33 is provided on the belt 26. The belt tension clutch 33 is provided with a cable 33 a and is connected to the grain discharge lever 22 of the operation unit 6.
[0017]
A bevel gear 29 is fixed to the other end of the input shaft 27a of the bevel case 27 and meshes with the bevel gear 30 that has been changed in direction by 90 °. A shaft 31 is fixed to the bevel gear 30, and the shaft 31 extends forward. A pulley 32 supported by the chassis 2 is fixedly provided at the end. The belt 34 wound around the pulley 32 is wound around the rotating shaft 7c of the blower 7 and the pulley 7d fixed thereto.
[0018]
When the grain in the glen tank 5 becomes full during the cutting operation in the field, the motor 18 is driven to place the grain discharge auger 8 at any position desired by the operator (such as a truck bed or a bag). Swivel to. And the hydraulic cylinder 20 provided between the vertical steel pipe 19 and the horizontal steel pipe 21 is driven, and the grain discharge port 8a is located in a desired position.
[0019]
Next, the grain discharge lever 22 provided in the operation unit 6 is set to the on state. Then, the cable 33a is pulled and the belt tension clutch 33 tensions the belt 26, and the power from the engine 2a passes through the counter case 24, the belt 26, the bevel case 27, and the shaft 31 from the output shaft 2b to the blower 7. , The blower 7 starts rotating. After the predetermined time, the electric motor 13 is driven and the feeding device 15 is driven. This is because when the electric motor 13 is driven first and the feeding device 15 is driven, the grain is not conveyed and is jammed below the feeding device 15.
[0020]
As a result, air is sucked from the suction port 7 a of the blower 7, discharged from the discharge port 7 b, passes through the pipe 16, and merges with the grain fed by the feeding device 15 below the feeding device 15. Then, it passes through the pipe 17 and is discharged out of the machine from the grain outlet 8a.
[0021]
Thereby, it is possible to prevent the grains in the Glen tank 5 from being damaged. In particular, the discharge of the helix is effective in conveying soybean, which is one of easily damaged grains. Even if it is other than soybeans, it is effective in preventing damage in transporting grains such as straw, wheat and buckwheat. Moreover, since the conventional spiral can be abolished, it also reduces the weight.
[0022]
However, if the rotational speed of the blower 7 is made variable according to the difference in the specific gravity of the grain, damage to the grain can be further prevented. That is, it is configured such that the rotational speed of the blower 7 is slow for a light specific gravity (buckwheat) and the rotational speed of the blower 7 is fast for a heavy specific gravity (wheat). As a result, any grain can be efficiently transported and discharged without being damaged.
[0023]
Moreover, when the angle of the horizontal steel pipe 21 is large (the state where the position of the grain discharge port 8a is high from the ground), it will be against gravity, so the grain conveying ability will be reduced. Therefore, the rotational speed of the blower 7 is increased as the angle of the horizontal steel pipe 21 increases. This speeding up configuration may be proportional or may be increased in a quadratic curve depending on the situation. Thereby, the grain is discharged out of the machine without being damaged efficiently.
[0024]
The temperature of the air discharged from the discharge port 7b is higher than that of the suction port 7a of the blower 7 due to adiabatic compression. Therefore, since the grain in the Glen tank 5 is conveyed with high temperature air, the grain can be dried by receiving a drying action during conveyance. As a result, the drying time of the dryer required in the subsequent process is shortened, so that the fuel and energy of the dryer can be saved.
[0025]
As shown in FIG. 3, the blower 7 is arranged between the operation unit 6 and the glen tank 5 with respect to the arrangement position of the blower 7. Thereby, since the distance between the discharge port 7b of the blower 7 and the feeding device 15 is shortened, it becomes possible to suppress the pressure loss to a minimum, and therefore the grains can be maintained in a state in which the air carrying capacity is maintained. Since it can be vigorously conveyed to the grain outlet 8a, clogging and the like can be prevented.
[0026]
Further, as shown in FIG. 4, a joint 9 is provided between the blower 7 and the feeding device 15. As shown in FIG. 4, the Glen tank 5 is configured so as to be pivotable laterally with the rear pivot fulcrum 5 a as an axis, so that the Glen tank 5 can be easily moved to the side by removing the joint 9. It becomes possible to turn to the direction. If the joint 9 is not provided, the Glen tank 5 is configured to rotate sideways with the blower 7. However, if configured in this manner, the weight of the Glen tank 5 itself increases, so that the rotation fulcrum 5a. The Glen tank 5 and the like must be firmly configured, and the acting force for rotating the Glen tank 5 is heavy, which is disadvantageous in configuration.
[0027]
Next, FIGS. 6 and 7 will be described.
The blower 7 is provided below the grain tank 5 and on the threshing device 4 side. Thereby, since the space part which exists under the Glen tank 5 can be used effectively, it can prevent affecting the grain quantity which can be stored in Glen tank 5. Further, since the blower 7 is located on the threshing device 4 side away from the operation unit 6, the noise generated from the blower 7 serves as a sound insulation by the Glen tank 5 main body, so that the noise of the operation unit 6 is reduced. Can do.
[0028]
Next, FIG. 8 will be described.
In this configuration, the blower 7 is provided between the operation unit 6 and the grain tank 5, and the extension of the grain tank 5 to the upper side of the blower 7 is provided to provide an extension part 5 d. Thereby, the capacity in the Glen tank 5 can be increased regardless of the position of the blower 7.
[0029]
The above-described counter case 24 (FIG. 5) is configured to be disposed in front of the first elevator 35 that puts the grains selected in the threshing device 4 into the Glen tank 5. Thereby, it can prevent that the grain quantity which can be stored in the Glen tank 5 reduces. Assuming that the elevator 25 is at the side of the counter case 24, the left end face of the Glen tank 5 moves to the right accordingly, so that the number of grains that can be stored in the Glen tank 5 is reduced. End up.
[0030]
The bevel box 27 (FIG. 5) in the middle of driving the blower 7 is arranged on the lower side of the belt tension clutch 33, and therefore is driven only when the belt tension clutch 33 is in the engaged state. . Therefore, even if the engine 2a is driven, the bevel box 27 is stopped, so that the durability of the bevel box 27 is improved and noise is reduced. Further, since the belt tension clutch 33 and other transmission members are, of course, disposed in the space below the Glen tank 5, this space can be used effectively, and the capacity of the Glen tank 5 can be reduced. Can be prevented.
[0031]
Next, FIG. 9 will be described.
FIG. 9 shows a front view of the Glen tank 5. The lateral rotation of the Glen tank 5 is configured to rotate about the rear rotation fulcrum 5a as described above, and the front locking device 36 will be described.
[0032]
When the lever 37 is pulled clockwise, the plate 38 rotates clockwise around the rotation fulcrum 39 as an axis. Then, the pin bar 40 moves upward and comes out of the hole 45 of the chassis 2 and the plate 42 rotates about the fulcrum 42a via the plate 41. It comes off from the frame 44 fixed to the 4th side. In this state, when the lever 37 and the Glen tank 5 main body are further pulled, the Glen tank 5 rotates to the side. When the Glen tank 5 is stored, if the lever 37 is released from the hand after being set at a normal position, the pin bar 40 enters the hole 45 of the chassis 2 due to the pulling force of the spring 46, and the plate 42 The hook 43 engages with the frame 44 on the threshing device side 4. Thereby, the lock of the Glen tank 5 is completed.
[0033]
At this time, the belt 34 between the drive pulley 7d of the blower 7 and the upper pulley 32 is provided with the belt tension 47 on the glen tank 5 side. Therefore, it is necessary to remove the belt tension 47. . Therefore, when the lever 48 is moved to the position 48 ′ and hooked on the hook 51, the belt tension 47 moves to the position 47 ′, so that the belt 34 can be detached from the drive pulley 7d of the blower 7. Also, when removing the belt 34 to the lever 48 by setting the drive pulley 7d of the blower 7 from the hook 51, by the tension force of the spring 50, since the belt tension 47 is tensioned, it is possible to transmit the power.
[0034]
Next, FIG. 10 will be described.
In the relationship between the lower merging portion of the feeding device 15 and the lower conveyance pipe 17, an inclined portion 15 b is provided so as to increase from the merging portion to the pipe 17. Thereby, the grain is handed over to the pipe 17 without being clogged.
[0035]
【The invention's effect】
Since the distance between the air conveying force generation means 7 and the Glen tank 5 is shortened and air pressure loss can be prevented, the grain is efficiently conveyed.
[0036]
Further, since the inclined portion 15b is configured such that the conveying portion becomes wider as it extends from the joining portion to the conveying pipe 17, the grain is taken over and conveyed to the conveying pipe 17 without being clogged. The air conveying force generating means 7 is driven through a belt tension clutch 33 and a bevel case 27 disposed on the rear side of the air conveying force generating means 7 and the belt tension clutch 33 is driven. Since the bevel case 27 is arranged in the space below the Glen tank 5, the space can be used effectively.
