Threshing device with combined clamping of two side plates and adjustable threshing gap and combined harvester

Abstract

The invention provides a threshing device with combined clamping of two side plates and an adjustable threshing gap and a combined harvester. A concave grid type plate comprises grid bars, side platesand a threshing gap adjusting device, the side plates are respectively inserted in the two ends of each grid bar, the grid bars are in clearance fit with the side plates, and the threshing gap adjusting device is arranged on the grid bars, so that the grid bars move radially and tangentially in gaps. The two side plates comprise the outer side plate and the inner side plate; the outer side plateis movably installed in a guide groove; the threshing gap adjusting device comprises a tangential adjusting device body and a radial adjusting device body, and the radial adjusting device is installedon the grid bars; one end of the outer side plate is connected with the tangential adjusting device body, and the tangential adjusting device body tangentially rotates along the guide groove throughthe outer side plate and is used for making the grid bars move tangentially in the gaps. The device directly adjusts the grid bars, is simple in structure, convenient and easy to operate and capable of effectively solving the problem that during work of the combined harvester, material accumulation and blockage occur in a threshing roller.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a threshing device and a combine harvester with adjustable threshing gaps between clamping double-side plates. Background technique [0002] Threshing is an important link in agricultural production. After the materials are harvested, the grains need to be separated from the chaff to obtain a mixture of grains and chaff for further cleaning. When the combine harvester is harvesting in the field, the grain is cut off by the header and fed to the threshing and separating device through the intermediate conveying device. The lower grains are separated from the concave plate sieve and enter the subsequent cleaning, and a large number of intact stalks are discharged out of the machine. During harvesting, the feeding amount will fluctuate with the distribution density of the crops in the field, which will directly lead to changes in the load of the threshing drum, which will not ...
