Abstract

PURPOSE:To enable the rocking grader to perform a good grading in the case of a large amount of materials to be treated in the rocking grader provided with plural straw racks in the rear of an upper grain pan and applicable to the wetted materials to be threshed. CONSTITUTION:This rocking grader for a thresher is constructed by installing a chaff sieve 15 on an upper grain pan 11, feeding materials which are leaked down from the chaff sieve 15 and to be treated onto the upper grain pan 11 and simultaneously conveying straw wastes fed to the rear with the chaff sieve 15 to straw racks (12a), (12b) and (12c) in the rear of the upper grain pan 11 and further providing a flow-down plate 16 for guiding the materials which are leaked down from the front straw rack (12a) and to be treated to an intermediate part in the conveying direction of a grain sieve 14 in the lower part, below the front straw rack (12a) in the straw racks (12a), (12b) and (12c) in the rear.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oscillating sorting device for a threshing device.

[0002]

2. Description of the Related Art Conventionally, as shown in Japanese Unexamined Patent Publication No. 4-207114, a rocking / sorting device for a threshing device is provided with a chaff sheave and a straw rack sequentially behind an upper gren pan, and an auxiliary glen pan below the chaff sheave. With a structure that includes a glen sieve and
As disclosed in Japanese Patent No. 928, there is a structure in which a plurality of Straw racks are provided behind the upper Glen pan, and an auxiliary Glen pan and a Glen sieve are provided below the Straw rack.

[0003]

The structure in which the chaff sheave is provided at the rear of the upper gren pan is capable of sorting the processed products better than the structure in which the straw rack is provided immediately after the upper gren pan. Although it has the advantage that the chaff sheave is a plate along the lateral direction, when threshing a wet culm, the treated product easily adheres to the chaff sheave and the inconvenience that the chaff sheave is easily clogged occurs. there were. On the other hand, the structure having a plurality of Straw racks in the rear of the upper Glen pan has the advantage of being able to perform a sorting process without causing clogging against wet threshing because the Straw racks are plates along the front-back direction. When a large amount of processed material is used, a large amount of processed materials fall downward, so that the processed material from the Straw rack drops onto the specific gravity sorted processed material by the lower Glen pan, which hinders the sorting processing by the lower Glen pan. was there. An object of the present invention is to make it possible to favorably perform a sorting process regardless of wet threshing and the amount of processed products.

[0004]

In order to achieve the above object, the present invention is characterized in that a straw rack is provided at the rear of an upper Glen pan, and an auxiliary Glen pan and a Glen sieve connected to the auxiliary Glen pan are provided at a sheave case. In the rocking sorting device of the threshing device, a chaff sheave is provided on the upper part of the upper gren pan, and the processed material leaked from this chaff sheave is supplied to the upper part of the glen pan. It is configured to be conveyed to a straw rack at the rear of the Glen pan, and further, a leakage treated material from the front straw rack in the rear straw rack is located at an intermediate portion in the transport direction of the lower gran sheave. The point is to provide a flow-down plate to guide.

[0005]

[Function] Considering the threshing condition in the handling room, the grain in the first half of the handling room is threshed where many grains are attached to the culm. In the latter half of the handling room, the grain culms are threshed after the grain has fallen, so in the latter half of the net, many cutting straws fall. In this way, the properties of the processing objects falling in the first half and the second half of the receiving net are different. And, since it is straw chips that easily adhere to the plate and grains that do not easily adhere to the plate, among the leaked substances from the handling room, the sorting place where the leaked substances are difficult to adhere, that is, the handling A chaff sheave with good sorting performance is installed in the first half of the chamber, and a straw rack is provided in the second half of the handling chamber, where leaked substances are likely to adhere, so clogging against wet threshing is prevented. It can be sorted without causing it. Then, if the processed product from the Straw rack is dropped onto the lower Glen pan as it is,
Although it will fall on the specific gravity sorted product by the lower Glen pan, it will reduce the sorting performance in the lower Glen pan,
By providing a downflow plate and allowing it to flow down to the middle portion of the Glen sieve, the sorting performance in the lower Glen pan is not deteriorated.

[0006]

As a result of the above construction, a swing sorting apparatus for wet threshing application having a plurality of straw racks behind the upper Glen pan is used, and in the lower Glen pan when the threshing treatment amount is large. The reduction of the sorting performance is separated into grain and straw waste in advance by the chaff sheave arranged on the upper part of the upper Glen pan so that only the grain flows down to the upper and lower Glen pan, and the leakage from the Straw rack Items are dropped to the middle part of the Glensieve by the falling plate so that the substances leaked from the Straw rack do not adversely affect the sorting performance in the lower Glen Pan. Good sorting process can be performed without degrading the sorting performance in Glen Pan.
