The present invention relates to a rocking separator of the threshing apparatus.

In the conventional threshing apparatus, the processed material conveying surface of the rocking | pulverization sorting apparatus is mainly comprised by chaff sieve, but as an example, it is a grain board of the front part as disclosed in Unexamined-Japanese-Patent No. 1-109937. It is known that the straw straw body for the crude selection was known from the grain pan back.

Compared to the rice straw conveying apparatus formed by installing a rack plate along the conveying direction of the processed object, the rice straw body is formed by arranging the chaff lip plates in a direction orthogonal to the conveying direction, so that it is easy to exhibit stable sorting performance. have.

The oscillation screening device functions to discharge the first article to be sorted out and recovered from the conveying surface, while the first article, etc., to be sorted and recovered by the lower collecting section is discharged. As described above, since a plurality of chaff plates are provided in a direction orthogonal to the conveying direction, it is impossible to carry them while the branched hell or straw climbs on the chaff plate and the rice straw body becomes clogged.

An object of the present invention is to solve the above problems and to provide a rocking-screening apparatus capable of exhibiting good screening performance.

In order to achieve the above object, in the rocking separator of the threshing apparatus according to the present invention,

1) a water net installed along the outer periphery of the threshing apparatus described above; and 2) a grain plate and a front rice straw feeder continuous to the rear of it to coarsely sort out the treatment material leaked from the water net. 3) a first rice straw feeder having a plurality of first rack plates, installed at a rear position of the front rice straw feeder as described above, and capable of receiving and selecting discharges from the rosin port; A second rice straw feeder provided at a lower position of the rear of the first rice straw feeder, and 5) the front portion of the rice straw feeder, which is provided with a second rack plate in parallel to one side of the plurality of parallel racks in the rearward direction. It is composed of the front body line installed in the supported shape, the parallel pitch (P2) of the second rack plate is smaller than the parallel pitch (P1) of the first rack plate. The parallel pitch (P3) between is smaller than the parallel pitch (P1) of the first rack plate described above, and receives the processed object toward the second rice straw feeder (26) delivered from the grain plate posted by these rack plates and the body line. The conveying surface D to be turned over is formed.

In addition, the rear body line is provided in a shape such that one side is supported toward the rear side with a parallel pitch P4 smaller than the parallel pitch P1 of the first rack plate described above at the lower position of the first rice straw feeder.

According to the above-described configuration, the conveying surface does not contain a straw straw body, and thus, the conveyed surface does not become clogged as branched hells, straws, etc. accumulate as in the prior art.

As a result, even if a straw is placed on the rack plate of the rice straw feeder, the rack plate follows the conveying direction, so that it is conveyed backward as it is.

In addition, since the rice straw conveying device at the bottom of the pine tree where the branched leaves or straws are discharged has a larger bottle mounting value of the rack plate, the branched leaves with shorter lengths than the straws are sieved toward the collecting unit and dropped to be discharged. Is to be conveyed toward the back.

The conveyed material on the second rice straw feeder that is continuous to the first rice straw feeder described above is mostly straw, and only a small amount of rice (such as divided rice) is mixed, so that the parallel pitch of the second rack board is small. By doing so, while giving the last recovery opportunity to the rice to be recovered, it is possible to convey the discharge such as straw back to the rear.

Most of the treatments that are laid down from the water nets are rice that has been isolated by threshing, but sometimes there are branched hells that can pass through the water nets in a standing posture.

In this case, it is possible to sift the hell which is carried by the front sieve in the region of the front rice straw feeder.

Therefore, in the present invention, since the rice straw conveying apparatus is reasonably arranged, the conveying surface is formed to form a conveying surface, it is possible to realize the sorting apparatus which improves the performance while making it difficult to block the processed material on the conveying surface. Since the performance is also improved, the screening performance is further improved. In a preferred embodiment of the present invention, the rear side of the first rice straw conveying apparatus described above is supported on the rear side with the side pitch P4 smaller than the parallel pitch P1 of the first rack plate. In this configuration, the branched hell passes through the first rice straw feeder as it is, and is separated by the sieve above the sieve before falling to the recovery part. In this respect, there is an advantage that the screening performance in the region of the first rice straw feeder is also improved.
