In addition, the bucket type fried apparatus 3 is configured to be able to transmit each portion by transmitting from the transmission pulley 30 provided on the shaft of the second transfer spiral of the threshing apparatus 1 to the pulley 32 via the belt 31.

Other Embodiments The configuration examples shown in FIGS. 4, 5 and 6 are embodiments of a threshing device mounted on a general-purpose combine. This will be described below. The sorting belts 28, 28 ′ are composed of a pair of wide belts, and a dust outlet 29 is provided below the sorting net 8 that constitutes the handling chamber 9.
It is provided in the sorting room 11 in the part close to. That is, as shown in the drawings, the sorting belts 28, 28 'are arranged such that the starting end portion is located on the dust outlet 29 side and the trailing end portion is located on the upper side in the sorting direction, and is located at the center of the portions located on both outer sides of the machine body. The portion located on the side is provided with a low inclination, and the leaked unprocessed material is collected on the central position and dropped onto the swinging sorting shelf 10 on the sorting side.

The sorting belts 28, 28 'are constructed so that the lower one 28' in the rotational direction of the handling cylinder 7 can rotate at a higher speed than the upper one 28. Now, to describe the operation of this other embodiment, the unprocessed material that has leaked from the handling chamber 9 through the sorting net 8 and reached the sorting chamber 11 is handled in the general-purpose threshing device 1 of this type. Compared to the center side of the chamber 9, there is a tendency to leak more from both side plates (outer side).

Therefore, the unprocessed material leaked from the sorting net 8 directly swings on the upper side of the sorting chamber 11 to select the sorting shelves 10.
It drops to the top and is rocked and sorted, and at the lower side of the sorting chamber 11, that is, at a position near the dust outlet 29, the sorting belt 2
Drop on 8, 28 '. In this case, the untreated product has a large amount of both side plates, and moreover, there is a large amount of leakage on the lower side of the handling cylinder in the direction of rotation.

The unprocessed material that has reached the top is tilted lower on the center side than on both outsides, and the lower side in the direction of rotation of the handling cylinder 7 is rotated at high speed, so the unprocessed material is conveyed to the upper side of the sorting chamber 11 at the center. The side being conveyed to the side and being conveyed by the sorting bell 28 ′ which is rotating at a high speed, is quickly fed in a large amount.

As described above, the unprocessed material is transferred to the upper side of the sorting chamber 11 and dropped from the end portions of the sorting belts 28 and 28 'onto the swinging sorting shelf 10 below to perform the swinging sorting action. Therefore, in this other embodiment, the unprocessed material leaked from the sorting net 8 can take a longer sorting process as compared with the conventional one, and is biased from the handling chamber 9. It is possible to correct many things that have fallen in the transportation process and drop many in the central part. Therefore, the unprocessed material is
It has the feature that it can be reliably sorted, the number of third scattering is reduced, and it can be processed without waste.

Next, the operation will be described. First, when the rotating parts of the machine are driven to start the threshing work, the handling room 9
The grain culm supplied to is subjected to threshing processing by the rotating handling cylinder 7, leaks from the sorting net 8 and reaches the swing sorting shelf 10 of the sorting chamber 11. Then, the leaked substance is sorted by receiving the action of the wind sorting and the action of the swing sorting shelf 10 and sorted into the first grain, the second grain, and the third grain, and the first transfer spiral 4, respectively.
The second transfer spiral is sent as dust outside the machine.

In this way, the grains that have reached the first transfer spiral 4 are sent from the end of the first transfer spiral 4 to the bucket-type grain lifting device 3 by the jumping blades 12 and then raised by the bucket 19. The inside of the case 20 is fried upward. Then, the grain is supplied from the bucket 19 reaching the upper part to the transfer spiral 23 of the transfer device 21, conveyed, sent to the Glen tank 2 side, and discharged to the Glen tank 2 by the diffusion blade 24.

As described above, the grains are sequentially stored in the grain tank 2 as the work progresses, and when the amount reaches a predetermined amount, the work is interrupted and the grains are discharged out of the machine. Next, when performing maintenance, the Glen tank 2 is rotated about a support tool 17 provided on the discharge auger 15 as a fulcrum, and is moved away from the threshing apparatus 1 as shown by an imaginary line in FIG. Rotate.

In this way, the threshing device 1 and the grain tank 2 can be maintained relatively easily. Next, the bucket type fried device 3
As described above, the Glen tank 2 is left open (see FIG. 1), and is opened via the supporting device 20a as shown by the phantom line in FIG. Then, the bucket type fried apparatus 3 can easily clean the endless belt 18, the bucket 19, the extension portion of the first transfer spiral 4 and the like while slowly rotating the endless belt 18 in the opened state. is there.
