[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a threshing device and a grain tank arranged side by side, and the grain tank is attached to the grain discharging vertical screw conveyor so as to be swingably opened about the axis of rotation of the vertical screw conveyor. The bucket conveyor that lifts the No. 1 product to the grain tank is placed between the threshing device and the grain tank so that it is exposed to the outside when the swing of the grain tank is opened, and the transmission belt is placed between the threshing device and the bucket conveyor. The present invention relates to a bucket conveyer structure for collecting grain of a combine, which is arranged in.

2. Description of the Related Art Conventionally, as shown in FIG.
Belts 2 and 2 for vertical and vertical screw conveyors
The upper and lower intermediate case portions of the bucket conveyor 25 located in front of No. 8 were formed in the shape of a square tube having a quadrangular horizontal cross-section that cannot be locally disassembled.

[0003]

However, with the bucket conveyor 25 exposed to the outside, the transmission belts 27, 28 are provided.
Threshing device 26 and bucket conveyor 25 for exchanging
If you do this by yourself when passing it between
With the operator holding the square tube-shaped upper and lower intermediate case portions of the bucket conveyor 25, one hand is extended and the transmission belts 27 and 28 are inserted behind the bucket conveyor 25 and passed behind the bucket conveyor 25. An operation of extending the other hand of the transmission belts 27 and 28 and grasping the other is performed, and it is difficult for one person to work because the angular upper and lower intermediate case portions interfere with each other. An object of the present invention is to improve the structure of the bucket conveyor so that a single person can easily perform the work of passing the transmission belt between the threshing device and the bucket conveyor.

[0004]

A feature of the present invention is that a threshing device and a grain tank are arranged side by side so that the grain tank can be freely rocked and released around a rotation axis of a grain discharging vertical screw conveyor. A bucket conveyor that attaches and pumps the first product from the threshing device to the Glen tank is placed between the threshing device and the Glen tank so as to be exposed to the outside as the swing of the Glen tank is released, and the transmission belt is used as the threshing device. In the combine located between the bucket conveyor and the bucket conveyor, of the upper and lower intermediate case parts of the bucket conveyor, the outer section with a horizontal U-shaped cross section including the lateral outer wall and front and rear walls on the Glen tank side is detachably attached. There is something.

[0005]

In other words, when the bucket conveyor is exposed to the outside by swinging the Glen tank open, the upper and lower intermediate cases of the upper and lower intermediate cases of the bucket conveyor are removed. Since the corners located outside the part are eliminated, both arms can be sufficiently extended by passing both arms between the upper and lower buckets, and a single work of passing the transmission belt between the threshing device and the bucket conveyor can be easily performed.

[0006]

As a result, it has become possible to provide a combine excellent in maintainability in which one person can easily carry out a work of passing a transmission belt for a threshing device, a vertical screw conveyor or the like between the threshing device and a bucket conveyor.

EXAMPLES As shown in FIGS. 1 and 2, an axial-flow type threshing device 2 for threshing and selecting by putting all the culms from the pre-mowing treatment device 1 behind the shaving pretreatment device 1 for threshing and selection processing. Is provided
A grain tank 4 for collecting the first product from the threshing device 2 is arranged in parallel on the right side of the threshing device 2, a boarding operation unit 3 is provided in front of the grain tank 4, and an unloader 5 for discharging grains from the grain tank 4 is provided. A bucket conveyor that mounts the Glen tank 4 around the axis of rotation P of the vertical screw conveyor 5a so that it can be oscillated and opened, and pumps the No. 1 from the No. 1 picking screw conveyor 6 of the threshing device 2 to the Glen tank 4. 7 is arranged between the threshing device 2 and the grain tank 4, and two transmission belts 8 and 9 that are separately transmitted from the driving part E to the threshing device 2 and the unloader 5 are provided between the threshing device 2 and the bucket conveyor 7. A screw conveyor 10 which is arranged and supplies the grain from the bucket conveyor 7 to the center of the grain tank 4 is provided to constitute an all-cullet-type axial flow combine.

As shown in FIGS. 3 to 5, of the upper and lower intermediate case portions of the bucket conveyor 7, an outer portion 7a having a substantially U-shaped horizontal cross section including the lateral outer wall and the front and rear walls on the side of the grain tank 4 is formed. The lower case portion 7b and the upper case portion 7c supported by the threshing device 2 are bolted to the side wall 7d on the threshing device 2 side of the upper and lower intermediate case portions by bolts 12 while being bolted to the lower case portion 7b and the upper case portion 7c. It is attached so that it can be attached and removed freely. That is, in a state where the bucket conveyor 7 is exposed to the outside by swinging the Glen tank 4 open, the outer portion 7a is removed to eliminate the outer front and rear corner portions of the upper and lower intermediate case portions, and the upper and lower buckets 7f attached to the chain 7e are removed. By fully extending both hands through both arms, it is possible to easily carry out the work for one person to pass the transmission belts 8 and 9 between the threshing device 2 and the bucket conveyor 7.

As shown in FIG. 6, a swing pan case 23 disposed below a receiving net (concave) 14 surrounding the lower part of the handling cylinder 13 has a corrugated grain pan 15 and a large number of square holes in the plate. The square hole sheaves 16 and the chaff sheaves 17 formed with are arranged in the upper stage and arranged side by side in the processed product transfer direction, and the Glen pan 18, the Glen sieve 19, and the chaff sheave 20 are arranged in the lower stage and arranged side by side in the processed product transfer direction. Dynamic sorting case 2
A wind-selecting fan 21 that blows air to a wind-selecting passage formed below 3.
Is provided and an auxiliary fan 22 that blows air from below toward the front side portion of the square hole sheave 16 is provided. The wind selecting fan 21 is driven by a belt type continuously variable transmission (not shown), and the wind selecting fan 21 and the auxiliary fan 22 are also provided. And transmission belt 2
4, the wind-selecting fan 21 and the auxiliary fan 22 are configured to perform a synchronous shift.

[Other Embodiments] The specific configuration of the threshing device 2 can be appropriately changed. The objects to be driven and the number of installed transmission belts 8 and 9 arranged between the threshing device 2 and the bucket conveyor 7 can be appropriately changed. In the bucket conveyor 7, the specific structure for attaching the outer portions 7a of the upper and lower intermediate case portions to the detachable operation can be selected appropriately. The form of the combine and the harvest target do not matter.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
