A rice-wheat combine harvester threshing separation device

Abstract

The invention relates to a threshing and separating device for a rice and wheat combine harvester, which includes a No. 1 mounting plate, a No. 2 mounting plate, a rotating motor, a threshing roller and a concave plate. A rotating motor is installed on the side wall of the plate through a motor base, the output shaft of the rotating motor is connected with the left end of the threshing drum, the right end of the threshing drum is installed on the side wall of the No. Between the No. 1 installation board and the No. 2 installation board. The present invention can solve the existing problems such as non-adjustable concave gap, fixed sieve hole size, small application range and uneven distribution of crops existing in the existing rice-wheat separation process, and can realize the automatic threshing and separation of rice and wheat. It has the advantages of adjustable plate gap and sieve hole size, wide application range and uniform crop distribution.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a threshing and separating device for a rice-wheat combine harvester. Background technique [0002] Grain combine harvester, referred to as combine harvester, is a combined machine for harvesting crops. It was called Combine in the early 1950s. Agricultural harvesting machinery that directly obtains grain from the field. One of the main devices in the combine harvester is the threshing and separating device, which is mainly responsible for separating the crop grains from the stalks. According to the classification of threshing components, the threshing and separating devices mainly include threaded rod drum type, spike tooth drum type, bow tooth drum type and impeller type. When using the textured rod drum type threshing and separating device for operation, the gap between the concave plates has a great influence on the threshing effect. Influence, the gap between the conc...

Problems solved by technology

[0003] In order to make up for the deficiencies in the prior art, the present invention provides a threshing and separating device for a rice-wheat combine harvester, which can solve the problems of non-adjustable concave plate gap, fixed sieve hole size, small use range and problems existing in the existing rice-wheat threshing and separation process. Uneven distribution of crops and other problems can realize the function of automatic threshing and separation of rice and wheat. It has the advantages of adjustable concave plate gap and sieve hole size, wide application range and uniform crop distribution.
