In front of the chassis 2 having the traveling device 1, a harvesting device 3 for harvesting the planted grain culms and transporting it to the rear, and a grain culm conveyed from the harvesting device 3 and directing it to the feed chain 4 further behind. A supply / conveyance device 5 for conveying the material is provided. A threshing device 6 for performing threshing selection while transporting the grain culm transported from the supply transport device 5 on the chassis 2 while being transported by the feed chain 4.
A grain tank 7 for temporarily storing grains that have been threshed and selected by the threshing device 6 and an operating unit 8 are mounted. Also,
A vertical auger 10 and a horizontal auger 11 for discharging grains temporarily stored in the Glen tank 7 are installed, and the vertical auger 10 is capable of turning in the left-right direction with respect to the chassis 2 together with the horizontal auger 11. In the horizontal auger 11,
A grain discharge port 12 is provided at the tip end portion thereof so that it can be moved up and down.

When the combine constructed as described above moves forward to start the work, the planted culms are cut by the reaping device 3 and conveyed to the rear side, and fed to the threshing device 6 via the feeding and conveying device 5. It is transferred to the chain 4.
The grain culm that has been carried over to the feed chain 4 is
Threshing and sorting are performed by the threshing device 6 while being conveyed rearward by the feed chain 4, and the sorted grain is the first fried grain cylinder 9
It is thrown into the Glen tank 7 and temporarily stored.

When the grain in the grain tank 7 becomes full, the harvesting and threshing operation is interrupted and the combine is moved to an arbitrary position. Then, the vertical auger 10 is rotated, and the vertical position of the horizontal auger 11 is adjusted to position the grain discharge port 12 at a position desired by the operator, such as a truck bed. Then, when the grain discharge lever 26 provided in the operation portion 6 is put into the engaged state, the belt tension clutch 33 is brought into the engaged state, so that the power from the engine 28 causes the belt 29, the pulley 30, the belt 31, and the pulley 32 to move. Lower helix 27 fixed to pulley 32 via
Is transmitted to.

Then, the grains in the grain tank 7 are started to be conveyed by the lower spiral 27, and then the vertical auger 1 is used.
0, laterally transferred to the auger 11 and transferred to the grain outlet 1
It is discharged from 2 to the outside of the aircraft. Then, when the grains in the Glen tank 7 are discharged to the outside of the machine and the discharging work is completed,
The combine is run again to resume the mowing and threshing work.

As shown in FIG. 2, the Glen tank 7 is divided into an upper Glen tank 7a and a lower Glen tank 7b. When the upper gren tank 7a is placed on the lower gren tank 7b, the upper gren tank 7a is configured so as to be fixed to the deepest frying cylinder 9 most.
Then, if the upper grain tank 7a is removed from the deep-fried grain cylinder 9, the upper grain tank 7a can be easily attached and detached. Specifically, the bar material 13 is fixedly provided on the end of the first fried grain cylinder 9, a tap hole for a female screw is provided on the bar material 13, and the bar bolt 13 is fixed from above. And, when attaching and detaching the upper grain tank 7a, the most fried grain cylinder 9 is left, so it is necessary to make a hole 15 through which the most fried grain barrel 9 passes in the upper part of the upper grain tank 7a. However, if you make a hole that is too large, the strength will weaken, so it is better to use the minimum necessary size. in this case,
When attaching and detaching the upper grain tank 7a, it is moved in a substantially vertical direction so as to be attached and detached.

Since the hole 15 cannot be completely sealed even if the knob bolt 14 is tightened, a lid 16 is provided and tightened. A hinge 16 is provided on one of the left and right sides of the lid 16.
a, and a hole 16b is formed on the other side of the left and right. Then, the weld nut 16c is provided on the upper Glen tank 7a side.
Is fixedly provided, and is fixed by the knob bolt 17. Therefore, in order to operate the knob bolt 14 fixing the upper Glen tank 7a, the knob bolt 17 is removed and the lid 16 is opened.

As described above, the upper grain tank 7a of the grain tank 7 can be easily detached by removing the knob bolt 14, so that the maintenance management of the deep-fried grain cylinder 9 can be easily performed. Since the upper grain tank 7a is configured to be fixed to the first fried food container 9 which is a rigid body, it can be firmly supported, and the positional relationship between the upper grain tank 7a and the first fried food container 9 and The accuracy of the positional relationship between the tank 7a and the lower Glen tank 7b is improved. Further, the upper Glen tank 7a can be fixed to the lower Glen tank 7b without using a special member.

When performing maintenance, the upper Glen tank 7a
In order to remove, the knob bolt 14 is removed and the upper grain tank 7a is moved to the upper part of the substantially vertical direction, and is removed leaving the deepest fried food container 9 on the machine side. Then, after maintenance, the upper Glen tank 7a is attached to the fuselage side again, but in order to stabilize the mounting state of the upper Glen tank 7a with respect to the lower Glen tank 7b, the lower portion of the upper Glen tank 7a is squeezed to the left and right direction. The length in the front-rear direction is shortened so that the outer surface of the upper Glen tank 7a is fitted into the inner surface of the lower Glen tank 7b in a fitted state. As a result, the upper Glen tank 7a can be mounted in a stable state.

The upper grain tank 7a is arranged so that the uppermost portion of the deep-fried grain cylinder 9 is located in the upper portion of the grain barrel 9, that is, the lower side of the deep-fried grain barrel 9 in the grain conveying direction is accommodated in the grain tank 7. . That is, the outlet 9a of the first deep-fried food container 9 is located completely inside the Glen tank 7, and the outlet 9a is open in all directions of 360 ° in the circumferential direction. .

As described above, since the outlet 9a of the deepest frying cylinder 9 is located inside the grain tank 7, the grains discharged from the outlet 9a are biased to a part of the grain tank 7. It is possible to prevent the accumulation, and it becomes possible to store evenly in the Glen tank 7.

Next, in order to increase the storage amount of the upper grain tank 7a, it is necessary to extend the upper portion of the upper grain tank 7a upward and further extend it to above the threshing device 6. Therefore, the first deep-fried food container 9 is also configured to extend upward. However, in this case, especially the threshing device 6
In the upper part of the, the distance from the outlet 9a of the deep-fried grain cylinder 9 is the longest, so it is difficult to store the grains evenly. Therefore, as described above, the outlet section 9 of the first deep-fried grain cylinder 9
Since a is opened in all directions of 360 degrees in the circumferential direction, the grains discharged from the outlet 9a are evenly stored in the portion above the threshing device 6. become.

The upper grain tank 7a may be made of sheet metal, but since it is detachable, it is better to use a material that is as light as possible. Any light material may be used, but a synthetic resin material is preferable in terms of cost and ease of molding. As a result, the upper Glen tank 7a can be easily attached and detached.

As shown in FIG. 2, the handling barrel cover 18 covering the upper side of the threshing device 6 is constructed so that it can be opened and closed upward with a hinge 19 provided on the side opposite to the feed chain 4 side as a fulcrum. Therefore, when the upper grain tank 7a is configured to project above the threshing device 6,
Of course, even if the handle barrel cover 18 is completely opened, the handle barrel cover 18 should not come into contact with the upper Glen tank 7a.
The angle A of 1 is to ensure a repose angle at which the grain naturally flows and falls.

The bottom portion 21 of the upper Glen tank 7a
When the handle barrel cover 18 is opened with the angle A set to the angle of repose, the positional relationship between the bottom surface portion 21 of the upper glen tank 7a and the handle barrel cover 18 becomes substantially parallel. Thereby, the contact between the handle barrel cover 18 and the upper Glen tank 7a can be prevented, and the contact can be prevented even when the upper Glen tank 7a is tilted to some extent when the upper Glen tank 7a is attached / detached. Become.

Next, FIGS. 4 and 5 will be described. In the bottom portion 21 of the upper glen tank 7a, particularly when the grain is wet, the grain may become lumps and adhere to the wall surface, and the grain may not be completely discharged to the outside of the machine. .

Therefore, the bottom surface portion 2 of the upper Glen tank 7a
1 is provided with a vibrating device 22 for vibrating. The vibrating device 22 includes a motor 23, a rotary rod 24 connected to the output shaft of the motor 23, and cams 25 fixed to the rotary rod 24 at a plurality of locations (two locations in this embodiment). It is configured to be in contact with the bottom surface portion 21 of the upper Glen tank 7a. Further, the motor 23 is fixedly attached to the front surface side of the upper Glen tank 7a via a plate 26.

When the motor 23 is driven, the rotary rod 24 rotates, and the cam 25 also rotates accordingly. This cam 2
When 5 rotates, vibration is applied to the bottom portion 21 of the upper Glen tank 7a. As a result, the grains that have become lumps and adhere to the inner wall surface are loosened and fall downward, and are discharged from the lower spiral 27 of the lower Glen tank 7b to the outside of the machine.

A switch (not shown) for driving the motor 23 is provided on the operating portion 8, but the motor 23 is automatically turned on in association with the entering state of the grain discharging lever 26. You may comprise. In this case, the motor 23 will be driven even when the grain is not wet, so that a moisture detecting sensor 28 is provided in the upper grain tank 7a as a restraining means for the moisture detecting sensor 2.
The motor 23 may be automatically set to the ON state when 8 detects a moisture value above a predetermined value. The moisture detection sensor 28 may be installed at any place other than the upper grain tank 7a as long as it can detect the moisture value of the grain.

Further, a CCD camera (not shown) is provided in the upper Glen tank 7a to perform image processing such as binarization to automatically detect the lump state of the grain and automatically drive the motor 23. It may be configured to be driven.
