The transmission means from the air to the diffusion means must be removed. An object of the present invention is to provide a combine grain tank that prevents the above-mentioned problems.

[0004]

The above object of the present invention is achieved by the following constitution. That is, in the combine having the configuration described in the claims, the diffusion means 8 for diffusing the grains is provided above the lower spiral 7 for discharging the grains in the Glen tank 6, and the diffusion means 8 is driven. This is a combined grain tank in which the driving means 9 and the transmission means 10 are provided in the grain tank 6.

[0005]

Embodiments of the present invention will be described with reference to the drawings. 1 to 5 show a combine grain tank embodying the present invention. In front of the undercarriage 2 having the traveling device 1, a cutting device 3 for cutting planted grain culms.
A threshing device 5 for threshing and sorting the culm cut by the mowing device 3 while nipping and transporting the same with the feed chain 4, an operating unit 13 for operating a combine, and threshing by the threshing device 5. A grain tank 6 for temporarily storing the selected grains is provided. In the upper part of the Glen tank 6,
The grain discharge port 14a of the first deepest grain cylinder 14 for conveying the grains selected by the threshing device 5 is provided.

Further, a lower spiral 7 for discharging the temporarily stored grains to the outside of the machine is provided below the Glen tank 6.
A vertical auger 11 for taking over the grains transported from the lower spiral 7 and transporting the grains upward of the combine body is provided in the chassis 2.
Further, a horizontal auger 12 is provided on the vertical auger 11 so as to be able to move up and down. The driving of the lower spiral 7 will be described with reference to FIG.

The power of the engine 15 drives the traveling device 1 and the mowing device 3 and also drives the threshing device 5. The power for driving the lower spiral 7 is obtained from the shaft 16 for inputting power to the threshing device 5. That is, the bevel gear 17 is fixed to the end of the shaft 16 and meshes with the bevel gear 18. The bevel gear 18 is configured to rotate a pulley 19 and rotate a pulley 21 via a belt 20.
Pulley 21 is a lower spiral shaft 7a for rotating lower spiral 7
Is fixed to the end. A bevel gear 23 is fixed to an end of the lower spiral 7 on the lower side in the grain transport direction.
With the bevel gear 24. Further, a bevel gear 25 is fixed to the lower end of the vertical auger 11 in the grain conveying direction, and meshes with a bevel gear 26 of the horizontal auger 12.

Since the lower spiral 7 needs to be driven only when the grain is discharged, the belt 20 is provided with a tension clutch 22. In such a Glen tank 6, a diffusion means 8 for diffusing a grain is provided above the lower spiral 7. The diffusion means 8 will be described. The diffusing means 8 is located above the lower spiral 7 and has a configuration as shown in FIG. That is, the shaft 27 is rotatably supported by bearings on the front plate 6a and the rear plate 6b of the Glen tank 6.

An L-shaped bar 28 is fixed to the shaft 27, and a U-shaped bar 29 is fixed to the L-shaped bar 28. The L-shaped bar 28 is fixed substantially perpendicular to the shaft 27, but does not have to be perpendicular. The driving unit 9 for driving the diffusion unit 8 as described above is an electric motor (or a hydraulic motor), and is provided on the side wall of the Glen tank 6. The motor 9
There is a transmission means 10 for driving the shaft 27 between the time when the lower spiral 7 is driven and the lower spiral 7.
0 is also installed on the side of the Glen tank 6. Specifically, it is fixed to a front plate 6a forming a part of the Glen tank 6 with bolts or the like.

The transmission means 10 will be described. The output shaft of the motor 9 is connected to the shaft 10a by a spline, and a bevel gear is fixed to the other end of the shaft 10a.
It is configured to mesh with a bevel gear fixed to one end of the shaft 27. Therefore, the rotational force of the motor 9 is
It is transmitted to the shaft 27 via the line 0a.

The L-shaped bar 28 and the U-shaped bar 29 rotate around the shaft 27 by such a transmission means 10 to diffuse the grains in the Glen tank 6. .
The switch 43 for driving the driving unit 9 is provided by the operation unit 1.
3 is installed in the vicinity of the discharge lever 44 for starting the discharge of the grains in the Glen tank 6 which is installed in the Glen tank 6.
Reference numeral 2 denotes a configuration in which tension is applied to the belt 20 to transmit power to drive the lower spiral 7.

As described above, since the motor 9 for driving the diffusion means 8 and the transmission means 10 are provided in the Glen tank 6 itself, the Glen tank 6 is particularly turned to the side. In the configuration that
It is not necessary to attach and detach the transmission means 10 each time. That is, if the motor 9 is installed on the machine side instead of the Glen tank 6 side, as shown in FIG. , The transmission means 10 must be attached and detached,
Although the trouble that it is very troublesome occurs, there is no need to perform such troublesome operation. Further, the dust is less generated on the Glen tank 6 side than on the threshing device 5 side, so that the motor 9 is also protected.

Since the transmission means 10 is arranged between the Glen tank 6 and the operation unit 13, the state of the transmission means 10 (the presence or absence of rotation, failure, etc.) is confirmed by the operator at the operation unit 13. There is an advantage that it is easy. Next, FIG. 7 will be described. Motor 9 and transmission means 10
(In the case of the present embodiment, the motor 9) does not protrude above the upper end 6 c of the Glen tank 6. As a result, the body can be made compact and the appearance can be improved. In addition, if it is located at a lower position, it becomes easier to perform maintenance management.

Next, FIG. 8 will be described. Diffusing means 8
The motor 9 and the transmission means 10 for driving the
It is configured to be installed inside. At this time, it is of course necessary to cover the motor 9 and the transmission means 10 with a cover or the like (not shown) so that the grains in the Glen tank 6 do not affect the motor 9 and the transmission means 10. With this configuration, it is possible to prevent the motor 9 and the transmission means 10 from being accidentally hit and damaged when the Glen tank 6 is rotated to the side as shown in FIG. Further, the motor 9 and the transmission means 10 can be installed even in a model having a layout in which the distance between the Glen tank 6 and the operation seat 13 is narrow due to the structure of the combine. The appearance also improves.

Next, FIG. 9 will be described. When the grains are in a wet state, when the lower spiral 7 is driven to discharge the grains outside the machine, the grains adhere to the side wall inside the Glen tank 6 (bridge phenomenon) and the grains are completely removed. May not be discharged. Therefore, the configuration of FIG. 9 prevents this problem.

In the configuration shown in FIG. 8, the power from the motor 9 is merely transmitted by the shaft 10a constituting a part of the transmission means 10, but the spiral 10b is connected to the shaft 10a. And the spiral 1
The grain transport direction of 0b is the lower direction of the Glen tank 6, that is, the lower spiral 7 direction. Thereby, the lumps of grains adhering to the inside of the Glen tank 6 can be broken and discharged out of the machine. Next, FIGS. 10 to 12 will be described.

The grain stalks cut by the cutting blade 30 of the cutting device 3 are conveyed rearward by the front conveying device 31 and transferred to the supply conveying device 32. The cereal stem transferred to the supply / transport device 32 is further transferred to the feed chain 4 of the rear threshing device 5. When the cereal stem is handed over to the feed chain 4, it is necessary to adjust the handling depth according to the length of the cereal stem. That is, if the culm is a short culm having a short length, when the threshing is performed by the handling cylinder 35 of the threshing device 5, the tip portion of the grain culm where the grain is present does not act on the teeth of the handling cylinder 35. , Unhandled parts occur. In addition, if the length of the culm is long, the portion where no grain is present is threshed when threshing with the handling cylinder 35, so that many straw chips are generated.

An appropriate threshing state in which the above-mentioned problems do not occur is when the spike portion of the cereal stem passes between the handling depth sensors 33 and 34 of the feeding and conveying device 32. Depending on the depth, the tip of the cereal stem is handled by the depth sensor 33,
34. When the cereal culm is a short culm, the handling depth sensors 33 and 34 do not detect the spike portion of the cereal culm.
The starting end of the upper side in the conveying direction of No. 2 is rotated downward about the fulcrum 37 so as to clamp the stem side of the grain stem.
Therefore, even when the feed chain 4 is handed over, the base of the cereal stalk is held more tightly, so that the tip portion of the cereal stem is handled by the handle 35.
To work. As a result, it is possible to prevent unhandled short culm.

When the grain culm is a long culm, the handling depth sensors 33, 3
4 is a time for detecting the tip portion of the grain culm, and at this time, the upper end of the feed conveyance device 32 in the conveying direction is rotated upward around the fulcrum 37 by the motor 36, so that the tip side of the grain culm is higher. So that it is pinched. Therefore, even when the feed chain 4 is handed over and held, the tip side is further held, so that a portion where there is no grain other than the tip portion of the grain stem does not act on the handling drum 35. Thereby, the generation of straw waste at the time of long culm is reduced.

As described above, when the supply / conveyance device 32 is moved and adjusted in accordance with the short culm and the long culm, an appropriate handling depth is obtained. At this time, the tip portion of the cereal stem is handled by the handling depth sensors 33, 3
4, the state is such that only the handling depth sensor 33 is detecting the tip of the cereal stem. At this time, the drive of the motor 36 for moving the supply / conveyance device 32 is stopped.

When the combine is moved to the next field after the operation is completed while adjusting the handling depth of the grain culm as described above, the starting end of the feeding and conveying device 32 in the conveying direction is higher than the lowermost position. , The weight of the supply and transport device 32 is supported at two points, the link portion 36a and the fulcrum portion 37. When moving to the next field in such a state, if the combine is moved at a high speed, the supply and transport device 32 swings, and the link portion 36a and the like may be damaged. Therefore, the operator manually lowers the starting end of the supply / conveyance device 32 in the conveyance direction to the lowermost position and abuts the stopper 38. Thus, since the supply / conveyance device 32 is supported at the three points of the fulcrum 37, the link portion 36a, and the stopper 38, it is possible to prevent an excessive load from acting on the link portion 36a and the like, thereby preventing damage.

However, it is troublesome to lower the supply / conveyance device 32 manually, and it is desired to automatically lower the supply / conveyance device 32. Therefore, as conditions for this, the cutting state of the grain stalk sensor 40 installed in the mowing device 3 and the handling depth sensor 33,
34, the cutting state, the cutting state of the cutting clutch lever 41 for turning on and off the driving force to the cutting device 3, and the cutting state of the threshing clutch lever 42 for turning on and off the driving force to the threshing device 5 are supplied only when they are aligned. The transport device 32 is automatically lowered to the lowermost position.

The detection of the disengaged state of the mowing clutch lever 41 and the threshing clutch lever 42 is performed by providing a position sensor (not shown) at the base of each lever and detecting the disengaged state by a signal thereof. Thus, the end of the operation can be reliably detected, and the supply and transport device 32 is automatically lowered, so that the damage to the supply and transport device 32 as described above can be prevented.

When the combine finishes moving to the next field and resumes the work again, the conditions for automatically returning the feeder 32 moved to the lowermost position to the previous work position are as follows: The state in which the grain stalk sensor 40 installed in the reaper 3 is inserted, and the state in which the handling depth sensors 33 and 34 are both inserted,
The feeding state of the cutting clutch lever 41 for turning on / off the driving force to the cutting device 3 and the turning-on state of the threshing clutch lever 42 for turning on / off the driving force to the threshing device 5 are aligned, and the supply / conveyance device 32 is not moved to the original position. Automatically return to. Of course, for this purpose, the base of the output shaft of the motor 36 (the link portion 36 a
It is necessary to install a position sensor 39 in the refracting portion or the fulcrum 37 of the above, and store this position.

Thus, when the operation is resumed, the supply / conveyance device 32 can be reliably returned to the original position. As described above, when the supply / conveyance device 32 is returned to the original position, as another embodiment, the supply / conveyance device 3 is simply used.
2 may be set to a substantially middle position of the entire stroke from the lowermost position to the uppermost position. Thereby, when the handling depth adjustment by the handling depth sensors 33 and 34 is restarted, the time required for the supply / conveyance device 32 to reach the position where the normal handling depth is executed is shortened.

[0026]

As described above, according to the present invention, the diffusion means 8 for diffusing the grains is provided above the lower spiral 7 for discharging the grains in the grain tank 6 of the combine, and the diffusion means 8 is driven. Since the driving means 9 and the transmission means 10 are provided in the Glen tank 6, in the configuration in which the Glen tank 6 is turned to the side, it is not necessary to attach and detach the transmission means 10 each time. Further, since the dust is less generated on the Glen tank 6 side than on the threshing device 5 side, the drive means 9 is also protected.
