Threshing apparatus

Abstract

The present invention discloses a threshing apparatus, which is provided with a receiving network under a threshing roller; one rear side of a roller room that collects the threshing roller communicates with a front side of a processing room that collects a dust sending port processing roller through the dust sending port, which is capable of enhancing threshing efficiency of the threshing roller, and is capable of transporting substance unprocessed by the threshing roller from the roller room to the processing room in high efficiency. In a first receiving network (71) of a receiving network (44) that located on one front side of the dust sending port (47), a plurality of longitudinal panel components (73) with plate surface facing front and back along the threshing roller (43). A plurality of linear components (74) seen from a cross section view are in circular shape roughly, in a state of alternating on holes (73a) of the longitudinal panel components (73) along axial direction of the threshing roller (43), and are arranged along circumferential direction of the threshing roller (43).

Description

technical field [0001] This invention relates to the threshing apparatus provided with the threshing cylinder and the dust delivery port processing cylinder, and arrange|positioning the receiving net in the lower periphery of the said threshing cylinder. Background technique [0002] As a receiving net suitable for a threshing device, someone has proposed a scheme in which a plurality of openings are formed on a flat plate member by press processing (for example, refer to Japanese Patent No. 3846886, hereinafter referred to as Patent Document 1) , or by a plurality of longitudinal plate members along the circumferential direction of the threshing cylinder and a plurality of wire pieces along the axial direction of the threshing cylinder to form a scheme of receiving nets consisting of a plurality of openings (for example, refer to Japanese Patent Application No. 11-253044 publication, hereinafter referred to as Patent Document 2). [0003] However, as a receiving net suitab...

AI Technical Summary

Problems solved by technology

[0010] However, since the above-mentioned receiving net is formed by punching, even if the size of the punching hole is increased, the ratio of the opening area of ​​the entire punching hole to the area of ​​the entire receiving net will be increased from the viewpoint of strength or processing accuracy. There is also a limit to the ratio (aperture ratio)

[0011] On the other hand, in the receiving net described in the above-mentioned patent document 2, a plurality of openings are formed by the above-mentioned plurality of vertical plate members and the above-mentioned plurality of steel wire members. The above opening ratio can be increased, but on the contrary, the above-mentioned lumpy untreated matter tends to stay in the drum chamber, and as a result, there is a problem that the threshing efficiency deteriorates.
