Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rough sorting section for receiving a processed material which has leaked from a handling room and swinging and transferring it, and swinging a sorted processed material which has leaked from this rough sorting section. A coarse sorting section is provided with a fine sorting section that causes the grains to be sorted and leaked to the first one collecting section while being transferred, and the second one is dropped onto the second collecting section that is arranged on the lower side in the transfer direction. The present invention relates to an oscillating sorting device in a threshing device in which a Straw rack for receiving the discharged straws and discharging the straws is disposed on the lower side in the transfer direction of the fine sorting unit.

2. Description of the Related Art In the rocking sorting device in the above threshing device, conventionally, as shown in Japanese Utility Model Laid-Open No. 4-38234, a straw rack type rough sorting portion is provided and a lower portion of the rough sorting portion is provided. A corrugated plate-shaped grain pan section and a fine sorting section in which a grain sieve for grain selection is serially arranged on the lower side in the swinging and transporting direction thereof are disposed, and the processed material leaked from the rough sorting section is grained in the fine sorting section. The grain was sorted, and the second material such as the paddy with branch was dropped to the second collecting section on the lower side to be returned to the upper side of the transfer of the rocking sorting apparatus.

[0003]

In the above conventional structure, good threshing performance can be exhibited when the amount of threshed material is not so large. However, in recent years, further improvement in processing performance of a combine equipped with a threshing device is desired. In other words, small-scale part-time farmers are required to combine small-sized and low-cost combine while being able to work efficiently in a short time. As a result, it is necessary to increase the working traveling speed of the machine without increasing the size of the threshing device. In such a case, the threshing device having the conventional structure described above has the following problems. That is, as a result of accelerating the traveling speed as described above, the amount of the processed material put into the threshing device per unit time in the threshing device increases, and the amount of the leaked processed product from the handling room increases in proportion to this. Become. Then, the amount of leakage from the handling chamber exceeds the processing capacity of grain selection in the fine sorting unit, and the amount of the second processed product that cannot be processed in the fine sorting unit increases. Moreover, since these second processed products are returned to the swing sorting device again, the amount of the processed products on the swing sorting device increases, and straw chips are accumulated on the swing sorting device to cause clogging. Will be lost. Moreover, the grains are mixed into the straw scraps, and it is not possible to sort down and down,
There is also an adverse effect that the grain is discharged to the outside of the machine body through the stroke rack. Therefore, as a method of eliminating such a harmful effect, it is conceivable to increase the sorting area of the swing sorting device, but if this is done, the shape of the threshing device will become large, and the demand for downsizing cannot be satisfied. Becomes An object of the present invention is to provide a rocking / sorting device in a threshing device capable of improving the threshing treatment capacity without increasing the size of the threshing device by rational structure improvement.

[0004]

The features of the present invention are as follows:
At the upper and lower intermediate positions between the rough sorting unit and the fine sorting unit, the grain is sorted and leaked toward the fine sorting unit while swinging and transporting the sorted product leaked from the rough sorting unit, and discharged. A sorting mechanism is provided for sending straws toward the Straw rack, and the sorting mechanism is configured by arranging a plurality of corrugated rack plates extending in a cantilever shape in parallel in the process transfer direction in parallel. It is in.

[0005]

[Function] The processed material that has been handled and leaked in the handling room is swing-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 discharge straw rack. Grains and fine straw debris are sorted and leaked to the lower side. The spilled material is further oscillated and sorted by a sorting mechanism in which corrugated rack plates arranged in the upper and lower intermediate portions are arranged in parallel, and the broken straws and slightly larger straws contained in the spilled material are oscillated. It is effectively transferred by the feeding action of a plurality of corrugated rack plates, and is transferred to the discharge straw rack by the swinging transfer force and the sorting wind. The processed products mainly consisting of small straw scraps will be sorted out. Of the threshed products, large pieces of broken chips that are likely to cause clogging can be effectively discharged not only from the rough sorting section but also from the sorting mechanism on the lower side from the lower side in the transfer direction to the outside of the machine. As a result, even if the amount of processed material in the handling room is large, the amount of reduction of secondary rice, such as rice with branches, that is dropped and recovered in the secondary recovery section is suppressed to a relatively small amount, and swinging It is possible to prevent clogging due to the accumulation of straw debris on the sorting device.

[0006]

Therefore, by arranging the sorting mechanism having a rational structure at the vertical intermediate position between the rough sorting section and the fine sorting section, the sorting length and leakage area along the swing transfer direction of the swing sorting apparatus can be reduced. It is possible to suppress the second reduction amount to a small amount without increasing it,
Providing a threshing device with a high threshing treatment capacity without blocking the early clogging phenomenon caused by the accumulation of straw debris in the rocking sorting device and the second collecting part, without increasing the size of the device as a result. I was able to do it.
