Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application field] The present invention relates to a rocking and sorting apparatus for a threshing apparatus. [Prior art] Conventionally, as shown in JP-A-2-174608, a swing sorting case of a threshing apparatus has a front end side supported linearly and slidably by a guide rail, and a rear end side supported by a drive mechanism. Thus, it was configured to be able to reciprocate back and forth. [Problem to be solved by the invention] If the rising inclination angle with respect to the horizontal of the guide rail supporting the front end side of the swing sorting case is set to be large, the vertical movement component of the swing sorting case becomes large, and Leakage sorting performance is improved, but there is a problem that the transfer ability of the processed material is reduced.On the contrary, if the rising inclination angle with respect to the horizontal of the guide rail is set small,
The moving component in the front-rear direction of the swing sorting case is increased, and the transfer ability of the processed material is improved, but there is a disadvantage that the performance of the separation sorting of the processed material is reduced. On the other hand, the treated material that has leaked from the handling room falls a lot at the front end of the swing sorting case, so we want to improve the leakage performance of grains at the front end of the swing sorting case. Then, there is a demand for improving the feeding performance of straw waste. However, the conventional structure described above has a disadvantage that the transfer capacity is reduced when the leak sorting performance is improved, and the leak sorting performance is reduced when the transfer capacity is improved. An object of the present invention is to solve the above-mentioned drawbacks by devising a supporting structure of a swing sorting case. [Means for Solving the Problems] The characteristic configuration of the present invention for achieving the above object is that the front end side of the swing sorting case is supported by a support mechanism movable in the front-rear direction, and the rear end side is driven by a drive mechanism. Go back and forth The operation and effect are as follows. [Operation] The curved locus protruding upward from the support mechanism that supports the front end side of the swing sorting case has a large rising inclination angle with respect to the horizontal in the front half thereof and the rear half thereof. When the swing sorting case is driven in the front and rear direction, the vertical movement component of the swing sorting case is large in the first half of the curved trajectory, and the front and rear movement component of the swing sorting case is large in the second half. Therefore, the state of high leakage selection and the state of high feed performance are alternately repeated. [Effects of the Invention] As a result of the above configuration, the front end side of the swing sorting case supported by the support mechanism improves the leakage sorting performance of kernels at the front end of the swing sorting case, and at the rear end. The feed performance of straw waste is improved, and the sorting efficiency is improved as a whole. Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in Fig. 2, the processed material that has been threshed by the handling cylinder (1) and leaked from the receiving net (2) is subjected to specific gravity sorting by the Glen pan (3) at the front end of the swing sorting case (A). The chaff sieve (4) separates the swarf and kernels, and the spilled kernels and grain with branches are further subjected to specific gravity selection in the lower glen pan (5) and leaked from the Glen sheave (6). The grain thus obtained is collected in the first product recovery device (7), and the grain with branches is recovered in the second product recovery device (8) from the end of the grain sieve (6). The processed material discharged from the dust outlet (9) at the end of the receiving net (2) is separated into grains and straw chips by the chaff sheave (4), , Is sorted by the above-mentioned Glen Sheave (6). The processed material reaching the end of the chaff sheave (4) is sorted by a straw rack (10), and the grains and the grains with branches are collected by a second product collecting device (8). It will be released outside. Then, small straw chips falling from the end of the Glen sheave (6) and the end of the chaff sheave (4) are discharged out of the machine by the air blow by Karino (12) and the suction action of the dust exhaust fan (13). The swing sorting case (A) has a front end, a support mechanism comprising a guide rail (14) attached to the side wall of the threshing device and a roller (15) attached to the sidewall of the swing sorting case (A). (B) is slidably supported in the front-rear direction.
It is supported by a drive mechanism (C) consisting of an arm (17) in which an eccentric cam (16) that rotates around and an oscillating link (18) connected to the tip of the arm (17) is supported. It is configured to be able to reciprocate in the direction. The guide rail (14) of the support mechanism (B) is bent in an arc shape at the same curvature, and the curved locus (P) at the center thereof moves in the vertical direction of the swing sorting device in the first half in the workpiece transfer direction. As the component becomes large, the moving component in the front-rear direction of the swing sorting device becomes large in the latter half, that is, in the first half of the workpiece transfer direction, the rising inclination angle with respect to the horizontal becomes large. Further, in the latter half, it is mounted on the side wall of the threshing apparatus in such a manner as to be bent upward so that the rising inclination angle with respect to the horizontal is small. (Another embodiment) Alternatively, a configuration may be employed in which the rising inclination angle with respect to the horizontal is large in the first half of the curved locus, and the rising inclination angle with respect to the horizontal is small in the second half. Note that, in the claims of the utility model registration, reference numerals are written for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
