As a reaping and conveying device, the reel 18
The harvesting device 17 is disposed below the pulling reel 18. The grain culms pulled up by the pulling up reel 18 and then mowed by the mowing device 17 are sent to the center by the lateral feed auger 16 and taken over by the feeder chain 15 in the feeder house provided in the center. . The feeder chain 15 conveys it to the front end of the handling cylinder 1 and threshes it while conveying it backward in the handling chamber.

The handling cylinder 1 may have a handling tooth implanted therein, and may be a handling cylinder having a spiral blade wound around it. A receiving net 2 is arranged below the handling cylinder 1, and a grain flow plate 3 is arranged at the front end below the receiving net 2 so as to be vertically swingable with the front part as a pivot. Has been done.

An upper sorting belt 4 is arranged at the rear of the grain flow grain plate 3 and can be tilted up and down by rotating up and down around a pivot point of the front end in accordance with the amount of leaked grain. That is, when the amount of leaked grains is large, the slope is steep, and when the amount of leaked grains is small, the slope can be adjusted to be gentle.

The lower sorting belt 5 is provided at the rear of the upper sorting belt 4,
It is arranged in an overlapping state with respect to the upper sorting belt 4.

The peripheral speed of the upper sorting belt 4 is set to be slightly higher than the peripheral speed of the lower sorting belt 5.

Reference numeral 6 denotes an upper blocking member having a slight gap formed between the upper sorting belt 4 and the upper surface thereof, and reference numeral 7 denotes a lower blocking member having a small gap formed between the upper sorting belt 5 and the upper surface thereof.

An culm conveyor 8 is arranged at the rear of the lower sorting belt 5, and 9 is a second for returning the second reduced product coming out of the second auger 14 to the grain flow plate 3 or the handling room. It is a return conveyor.

The second return conveyor 9 has two return ports opened, and the return port 9a is a port for performing return to the handling cylinder 1,
The return port 9b is a port for performing return to the top of the grain flow grain plate 3.

A slide shutter 9c is arranged at the return port 9b.

Reference numeral 10 denotes a first conveyor, which conveys the first grain discharged from the sorting section to the outside by the first auger 12 to the storage tank 19.

(F) Action of the invention The shredding / sorting device configured as described above performs the sorting action as follows.

The grain culms that have been pulled up by the pull-up reel 18 and cut by the harvesting device 17 are conveyed to the handling room by the feeder chain 15.

After being shredded in the handling chamber, the net 2 leaks and falls.

Many of the fine grains in the falling grains are placed on the portion of the grain flow grain plate 3, slide down by the vertical swing of the grain flow grain plate 3, and ride on the upper blocking body 6. Then, on the upper sorting belt 4, sorting is performed by the sorting wind from the sorting fan 11 first. The upper sorting belt 4 is rotated in a direction to convey the grains placed on the upper surface upward, and soybeans, adzuki beans, buckwheat, etc.
The upper sorting belt 4 drops while rotating to the lower side opposite to the conveying direction, and reaches the auger 12 first.

The grains shredded in the rear part of the handling cylinder 1 pass through the receiving net 2 and are placed on the upper sorting belt 4 and the lower sorting belt 5 as they are, and the fine grains are the upper sorting belt 4 and the lower sorting belt 5. It is not conveyed in the upper direction, which is the conveying direction, but drops in the direction of the auger 12 most while rotating.

Further, the second object placed on the upper selection belt 4 and the lower selection belt 5 and conveyed upward, while being conveyed,
It is sorted by the sorting wind from the sorting fan 11.

An upper blocking body 6 is arranged with a gap provided between the upper sorting belt 4 and the upper surface, and a lower blocking body 7 is arranged with a gap also provided between the upper sorting belt 4 and the upper sorting belt 5. The grain that has passed through the gap between the dam body 6 and the lower dam body 7 passes through the first auger 12 and the first conveyor 10 and is stored in the storage tank 19
Stored in.

Those that cannot pass through the upper blocking body 6 and the lower blocking body 7 are sent rearward by the wind force of the sorting fan 11. Further, the branches and leaves with grains that could not leak through the receiving net 2 and foreign substances such as shavings fall from the end of the receiving net 2, and the culm fan 13
Selected by.

The branches and leaves with grains are discharged to the outside of the machine by the second auger 14 and reduced by the second reduction conveyor 9 from the reduction port 9a or the reduction port 9b so that they can pass through the upper dam body 6 and the lower dam body 7. It will be processed again with the missing one.

Further, the culms, shavings, etc. are blown off on the culm conveyor 8, conveyed upward and rearward, and discharged to the field scene.

(G) Effect of the Invention Since the present invention is configured as described above, it has the following effects.

First, since the sorting belts are arranged in the upper and lower two stages, the sorting capacity is increased as compared with the conventional case where only one stage of the sorting belts is arranged.

Secondly, even if the combine traveling speed is increased
It becomes possible to sort, and when traveling at low speed,
The sorting performance is better than before.

Thirdly, since the upper blocking body 6 and the lower blocking body 7 are arranged at the front ends of the upper sorting belt 4 and the lower sorting belt 5 with a gap therebetween, only the fine grains can be dropped to the auger 12 most. It has become possible.
