Sheller unit of combine

Abstract

The invention discloses a threshing device used for a combine harvester. The threshing device comprises a separate feeding chain, a holding rail, a threshing cylinder, a threshing cavity, a wobbling and sorting device and a corn storage device. The threshing cavity comprises a left side reinforcement plate, a right side reinforcement plate, a front side reinforcement plate, a rear side reinforcement plate and a cover. The threshing device is characterized in that a rotating shaft of the threshing cylinder is directly and fixedly installed on the cylinder; mounting grooves are formed on both the left side reinforcement plate and the right side reinforcement plate; the threshing cylinder is pushed into and installed between the left side reinforcement plate and the right side reinforcement plate in the bestriding manner; the left side reinforcement plate, the right side reinforcement plate, the front side reinforcement plate, and the rear side reinforcement plate are shaped by one-time pressing; plate-type reinforcement bars are arranged on the outer side surface of each plate surface; and a lower lip plate is arranged above the front side reinforcement plate, and a dismountable structure is installed between the lower lip plate and the front side reinforcement plate. The invention can firstly conduct the dynamic balance test to the threshing cylinder, so as to ensure that the cylinder has the advantages of normal operation and convenient disassembly and assembly.

Description

technical field [0001] The invention relates to the field of combine harvesters, in particular to the technology of a threshing device on the combine harvester. Background technique [0002] The threshing device of the combine harvester generally includes a receiving port, a distribution chain and a clamping track, a threshing drum, a threshing chamber, a swinging sorting device and a grain storage box device.

Strong plate, rear strong plate and top cover, the threshing drum is installed in the threshing chamber, the arc-shaped filter screen is installed under the threshing drum, the swing sorting device is set under the arc-shaped filter screen, and the right side of the strong plate The right side is equipped with a grass discharge chain device bracket and a grass discharge chain device. The distribution chain is equipped on the side circular rotating chain with conveying protrusion...

AI Technical Summary

Problems solved by technology

In the existing threshing device, the rotating shaft on the threshing drum is fixedly installed on the drum through bearings, so there is a disadvantage: the dynamic balance test of the threshing drum is difficult to do accurately and it is more troublesome to do, and the dynamic balance test can only be done after installation , the accuracy of the dynamic balance test cannot be guaranteed, which will affect the normal operation of the threshing drum
