2. Description of the Related Art Conventionally, as described in Japanese Utility Model Laid-Open Publication No. 4-38234, a swing sorting apparatus in the above-mentioned threshing apparatus is provided with a straw rack type rough sorting section and a lower portion of the rough sorting section. A fine sorting unit having a corrugated sheet-shaped grain pan portion and a grain sieve for grain sorting connected to the lower side in the swinging transfer direction is arranged, and the processed material leaked from the coarse sorting unit is grained by the fine sorting unit. It was configured so that the second product, such as grain-separated paddy and the like, was dropped to the second recovery unit on the lower side and returned to the upper transfer side of the rocking sorting apparatus.

[0003]

In the above-mentioned conventional structure, when the amount of threshing is not so large, good threshing performance can be exhibited. However, recently, further improvement in the processing performance of a combine equipped with a threshing device has been desired. In other words, small-scale part-time farmers are required to be able to work efficiently in a short time and to combine small and low-cost farmers. As a result, it is necessary to increase the work traveling speed of the machine without increasing the size of the threshing apparatus. In such a case, the following problems occur in the above-described conventional threshing apparatus. That is, as a result of increasing the traveling speed as described above, the amount of the processed material to be thrown into the threshing device per unit time in the threshing device is increased, and the amount of the processed material leaking from the handling room is proportionally increased. Become. Then, the amount of leakage from the handling room is larger than the processing capacity of the grain sorting in the sorting section, and the amount of the second processed material that cannot be processed in the sorting section increases. In addition, since these second processed materials are returned to the oscillating sorting device again, the amount of the processed material on the oscillating sorting device increases, and straw chips accumulate on the oscillating sorting device and clogging occurs. It will be. In addition, the grain is mixed into the straw and it is not possible to sort it down.
There is also an adverse effect such that the grains are discharged to the outside of the machine through the straw rack. Therefore, as a method of solving such an adverse effect, it is conceivable to increase the sorting area of the oscillating sorting device. However, in this case, the shape of the threshing device becomes large, and the demand for miniaturization cannot be satisfied. Becomes An object of the present invention is to provide a rocking and sorting apparatus in a threshing apparatus which can improve the threshing processing capacity without increasing the size of the threshing apparatus by rational structural improvement.

[0004]

SUMMARY OF THE INVENTION A rocking and sorting apparatus in a threshing apparatus according to the present invention comprises: a rough sorting section for receiving a processed material leaking from a handling room and performing a rough sorting while rocking and transferring; Sorting and dropping the cereal grains into the first material collection unit while rocking and transferring the sorted material that has leaked from the unit, and dropping the second product onto the second product collection unit located below the lower side in the transfer direction A rocking sorter in a threshing device provided with a separate part, and a straw rack for receiving the waste straw sent out from the rough sorting part and discharging the straw outward. In the upper and lower intermediate position between the coarse sorting section and the fine sorting section, the grains are sorted and leaked toward the fine sorting section while rocking and transferring the sorted product leaked from the coarse sorting section; A sorting mechanism that sends out the waste straw toward the straw rack is provided. In addition, the sorting mechanism comprises a plurality of sieve lines extending in a cantilevered manner along the processing object transfer direction arranged in parallel on the downstream side of the Glen pan portion in the transfer direction, and the fine sorting unit and the sorting mechanism And an air passage for flowing the sorting wind sent from the blowing means along the lower side of the sorting mechanism.

[0005]

[Working] The processed material that has been handled and leaked in the handling room is rocked and sorted in the rough sorting section, and large scraps such as broken straw are transferred to the lower side and discharged to the outside of the machine by the discharging straw rack, Grains and fine straw chips are sorted and leaked downward. Then, the leaked material is further rocking-sorted by a sorting mechanism arranged in the upper and lower middle portions, and the waste straw waste included in the leaked material is guided by the sorting wind to the lower side of the conveyance and is eliminated, and The processed material mainly composed of grains and small straw chips will be sorted and leaked to the fine sorting section on the side.
Furthermore, the sorting mechanism is composed of a plurality of sieve lines extending in a cantilever manner along the direction of transferring the processed material from the grain pan portion. Is effectively transferred by the feeding action of the glen pan portion that swings and the discharging action caused by the vibration of the free end side of the sieve wire, and is transferred to the discharging straw rack, and the straw and the grains are removed. Separation is improved and the grain recovery is increased. Therefore, large pieces of crushed chips that are likely to cause clogging out of the threshing processed material can be effectively discharged not only from the rough sorting section but also from the lower sorting mechanism to the outside of the machine from the lower side in the transfer direction. ,
As a result, even if the amount of processed material in the handling room increases, the amount of reduction of the secondary material such as the chaff with branches dropped and collected in the secondary collection unit is suppressed to a relatively small amount, and the shaking is suppressed. It is possible to prevent the accumulation of straw chips and clogging on the moving sorting apparatus as much as possible. Further, since the sorting wind passes below the sorting mechanism, that is, above the fine sorting part, the processed material is mountain-shaped on the fine sorting part, and a thick part of the layer is locally generated. Also,
This sorting wind evens out the grain, improves the grain drop sorting efficiency, and sends air passing between the sieve lines of the sorting mechanism, so that light straw chips and the like are easily blown backward. Then, by the air blowing, sufficient sorting air is given to the processed material on the sieve line and to the straw chips and the like that are blown from the sieve line to the straw rack, so that the grains mixed into the straw chips can be satisfactorily separated.

[0006]

Therefore, the sorting mechanism having a rational structure is arranged at the upper and lower intermediate position between the coarse sorting section and the fine sorting section, so that the sorting length and the leak area along the swinging transfer direction of the swing sorting apparatus can be reduced. The secondary reduction amount can be suppressed to a small value without increasing,
In addition to preventing the early clogging phenomenon caused by the accumulation of straw chips in the rocking sorting device and the secondary collection section,
The sorting wind that blows between the sorting mechanism and the sorting section in the processing material transfer direction promotes the grain leakage action in the sorting section, thereby improving the sorting efficiency and the grain recovery rate. Threshing equipment with high threshing processing capacity can be provided without increasing the size, and the processed material that has been subjected to specific gravity selection in the Glenpan section is shaken by a sieving line to fly straw debris etc. from its rear end to the back straw rack. In addition, the sorting air is blown between the sorting mechanism and the fine sorting section in the processing material transfer direction, so that not only the sorting process on the sieving line but also the straws Is further promoted, and the processing capacity is enhanced.
