Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a threshing machine equipped with a swinging sorting device that receives and swings the processed material leaking from a handling room.

[Conventional technology]

Conventionally, in order to configure the above-mentioned oscillating sorting device, for example,
As shown in FIG. 4 of Japanese Patent Publication No. 228412, a grain pan and a rack plate, or a grain pan and a chaff plate (not shown), were arranged in that order in the front and rear. The grain pans, rack plates, etc. were used to receive the processed materials from the handling room, and the specific gravity differences were sorted by shaking motion.

[Problem to be solved by the invention]

However, since the sorting is performed by shaking the grain pan, rack plate, etc., there is a limit to the sorting performance. In other words, if harvesting is carried out under conditions with a lot of morning dew and the processed material contains a lot of moisture or there is a large amount of processed material, the processed material will accumulate in multiple layers on the rack board, resulting in the leakage of fragrances. Bottom efficiency deteriorates. On the other hand, when the amount of material to be processed is small, there are cases where too much leakage occurs and waste straw is collected together with the material, making it difficult to adapt to all conditions.

Therefore, it may be possible to adjust the leakage ratio according to the amount of material to be processed, but even such adjustment of the gauge is still not sufficient.

The purpose of the present invention is to provide a rational mechanism in the leakage space between the handling room and the swinging sorting device, and to configure the swinging sorting device in accordance with this mechanism to improve the sorting performance of processed materials. be.

[Means to solve the problem]

The characteristic configuration according to the present invention is that a cross-feeding conveyance screw for cross-feeding the processed material leaking from the handling chamber is provided completely between the left and right threshing side plates, and a guide guide guides the processed material toward the cross-feeding conveyance screw. A leakage mechanism is provided, and a leakage mechanism is provided for leaking selected processed materials among the processed materials sent by the lateral conveyance screw, and the leakage mechanism prevents leakage at the conveyance terminal position of the lateral conveyance screw. A releasing device is provided to release the coarsely selected material, and a screening section receives the selected material from the leakage mechanism and performs shaking sorting, and a shaking device receives and shakes the coarsely selected material released by the releasing device. The oscillating sorting device is provided with a rough sorting section for dynamic sorting, and its effects are as follows.

[For production]

In other words, while the processed material leaking from the handling chamber is transported horizontally by the cross-feeding screw, the selected processed material containing a large amount of grains is dropped into the screening section via the leakage mechanism, and the selected processed material is Shake sorting is carried out in the fine sorting section. On the other hand, the roughly sorted material that has been transported to the terminal end of the horizontal conveyance screw and has not leaked out is released by the releasing device, and is then dropped and supplied to the rough sorting section, where the roughly sorted material is shaken. Select.

■ The cross-feeding conveyance screw and the leakage mechanism can separate the processed materials into finely-selected materials and rough-selected materials and supply them to the swing sorting device, and between the cross-feed conveyance screw and the leakage mechanism, Since it is possible to add a "kneading" effect to the processed material, it is also possible to provide the cross-feeding conveyance screw with a single-graining function.

(2) Since the material can be transported horizontally by the transverse transport conveyance screw, the selected material leaking from the leakage mechanism can be uniformly leaked in the lateral direction of the screening section.

■ Since the material to be roughly sorted is released by the releasing device, compared to simply dropping it, the releasing driving force of the releasing device can be directly applied to the material to be roughly separated as a "beating effect". , it is possible to knock out the "sasarii fir" that is stuck in the secondary material such as paddy with branches, and to improve the separation. Furthermore, by releasing the coarsely selected products, the two aromatic substances can be disentangled from each other at the time of release.

〔Effect of the invention〕

(a) From function ①, even if the amount of processed material is large or small, it is sorted in advance in the pre-process of the oscillating sorting device, so the material to be processed in the oscillating sorting device can be separated and dispersed, and the material can be carefully selected. Since the eyelets of the separate section and the coarse sorting section can be formed exclusively for them, the sorting performance can be further improved.

(W) Also, since the material to be processed is further dispersed in the swing sorting device than in operation (2), the sorting performance can be further improved.

From the above ((), (0), it is possible to greatly improve the sorting processing performance compared to the conventional structure, regardless of the amount of processing and the moisture content of the processed material.

(c) However, there is a device that achieves the same effects as those shown in (a) and (b) above, such as that disclosed in Japanese Utility Model Application Publication No. 6274540, but in this case, the transverse conveyance screw is At the terminal end, the coarsely selected material transported by the screw is simply dropped, so there is no "knocking" effect as shown in function (■) of the present invention, which eliminates the "chuckling" phenomenon. The effect is weak. Moreover, in the case of the present invention, it is also possible to expect a wind screening effect using the air discharged by the blowing device, and there is also an advantage that a sorting effect can be added to the material before it falls into the rough sorting section.
