Problems solved by technology

However, with the improvement of agricultural production capacity, the requirements for the production efficiency and production capacity of the threshing machine are getting higher and higher, and the fixed threshing cylinder concave plate assembly can no longer meet the production operation requirements. A new structure is developed. It is imminent for threshing machines to meet and adapt to production needs

Abstract

A threshing machine threshing cylinder concave assembly gear drive rotary mechanism belongs to the agricultural machine; an end of a threshing cylinder concave assembly is fixedly provided with a gear type tooth ring; the gear type tooth ring is uniformly provided with a plurality of pin shafts in a peripheral direction; ends on a same side of the pin shafts are respectively provided with a rolling bearing; the side portion of the gear type tooth ring is coaxially provided with rolling bearing ring seats which in radial, circumferential and axial positioning with the gear type tooth ring; the rolling bearings are arranged in annular rolling slideway slots of the rolling bearing ring seats; a driving gear is arranged on the side portion of the gear type tooth ring for mutually engagement; the rotary motions of the threshing cylinder concave assembly can be realized; the threshing machine threshing cylinder concave assembly gear drive rotary mechanism is novel, simple and reasonable in structure, reliable in usage, good in threshing work quality, and high in production efficiency.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a threshing device on a threshing machine tool. Background technique [0002] The threshing device on the threshing machine is mainly composed of two parts, the threshing cylinder shaft assembly and the threshing concave plate assembly. During operation, the threshing operation is carried out by the rotating threshing drum shaft assembly, and then with the cooperation of the fixed threshing concave plate assembly, the detached grains are separated from the separation device through the gap of the threshing concave plate assembly. Threshing and separation operations. On the threshing machines from the 1960s to the end of the century, the threshing concave plate assembly adopts an arc-shaped structure with an overall wrap angle of less than 180°, and is fixed under the threshing drum shaft assembly as a whole. The grains can only be discharged from the arc-shaped threshing concave p...
