DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain sorting device for a threshing machine.

[0002]

2. Description of the Related Art A conventional threshing machine is characterized in that threshing material leaking from a threshing net below a threshing room provided with a handling cylinder pivotally supported on a handling cylinder shaft provided from a starting end to a terminating side of grain culm transfer. And the threshing material discharged from the straw waste discharge port provided at the end of the threshing net at the end of the threshing net and not threshed from the threshing net, are subjected to rocking sorting provided below the threshing net. Transfer shelves, Glen sheaves, chaff sheaves, straw racks, etc. are provided sequentially from the top in the transfer direction at the upper part, and are supplied to a rocking sorting device equipped with a sorting screen at the bottom at the lower part. This is a grain sorting device that sorts and sorts into the first thing such as grain, the second thing such as spike sticking grain and the straw waste.

[0003]

The grain culm to be threshed is transported in the threshing chamber from the start end to the end side of the grain culm supply in the threshing chamber, and the grain culm being transported is pivotally supported by a handling cylinder shaft. Threshing by the rotation drive of the handling cylinder, threshed threshed is discharged from both the leak discharge from the threshing net below this threshing chamber and the straw waste discharge port at the end of the handling cylinder, It is supplied onto the rocking sorter, and is sequentially rocked and transferred to the transfer shelf, the Glen Sheave, the chaff sheave and the straw rack of the rocking sorter. And the waste is separated and sorted into straw waste, etc., and is further subjected to rocking sorting and pressurized air sorting by a sorting net. The first thing is discharged outside the machine, and the second thing is supplied to the processing room etc. The waste and the dust are discharged outside the machine.

[0004] During the above-mentioned threshing operation, an attempt is made to reduce the number of sticky branches attached to the first object such as grains.

[0005]

SUMMARY OF THE INVENTION The present invention provides a threshing chamber 14 provided with a handle drum 19 supported by a handle cylinder shaft 17 extending from the start end to the end side of grain culm transfer inside the grain threshing process. At the top of a rocking sorter 28 that rocks and sorts by receiving threshing material leaking from the lower threshing net 21, a transfer shelf 31, a grain sieve 32, a chaff sheave 33, a straw rack 34, and the like are sequentially arranged from the transfer direction starting end side. The grain of a threshing machine characterized in that an upper sorting net 35a of a predetermined mesh is provided on the upper side and a lower sorting net 35b having a larger mesh than the upper sorting net 35a is provided on the lower side. The structure of the grain sorting device is adopted.

[0006]

Operation and effect of the present invention The culm to be threshed is provided in the threshing room 14

The thresh is leaked and discharged from the threshing net 21 below the threshing chamber 14,
The waste is discharged from both the straw waste discharge port at the end of the handling cylinder 19 and supplied to the swing sorting device 28, and the transfer shelf 31, the Glen sheave 32, and the chaff sheave 3 of the swing sort device 28
3 while being sequentially rocked and transferred to the straw rack 34, etc., are separated and sorted into the first thing such as grain, the second thing such as spike sticking grain and straw waste, and the upper upper sorting net 35a and the lower one. With the lower sorting net 35b on the side, rocking sorting and pressurized sorting, which are separated and sorted into grains and spike sticking grains, are performed, and the first thing such as sorted grains is discharged outside the machine. Collected. The second product such as the sorted grain attached to the branch is supplied to a processing room or the like and reprocessed.
Sorted straw waste and dust are discharged outside the machine.

At the time of the above-mentioned threshing operation, the grain attached to the branch streak is:
During the transfer on the upper transfer shelf 31, the grain sieve 32, etc., it is separated and sorted by rocking sorting, and further, the upper and lower upper sorting net 3 on the lower side.
5a and the lower sorting net 35b again separate and sort the pieces by rocking sorting, so that there is no mixing of the spike sticking particles into the first thing such as the sorted grains.
