Drum mowing device of half-feed combine harvester

Abstract

The invention provides a drum mowing device of a half feed combine harvester. The drum mowing device comprises a supporting frame; a plurality of rib plates arranged between the two side walls of the supporting frame in the length direction, the blade hole positions are formed between the adjacent rib plates, supporting shafts are arranged between the two side walls of the supporting frame in the width direction, mounting seats are arranged at two ends of the supporting shafts, the supporting shafts are mounted on the supporting frame through the mounting seats and are provided with a plurality of blades in disc shapes, the edges of the blades correspond to the blade hole positions among the rib plates, each blade is fixed to the supporting shaft through two fixing seats arranged on two sides of the blade symmetrically, and shaft sleeves are arranged on the supporting shafts between the adjacent blades. When the drum mowing device is used, the smashing requirements of the harvester can be met during high speed mowing, the blades can be maintained more conveniently, grass twisting is avoided, and the drum mowing device is safer to use.

Description

technical field [0001] The invention relates to a harvester, in particular to a half-feed combine harvester drum mower. Background technique [0002] The detachment chamber of the semi-feeding combine harvester is mainly composed of a drum, a top cover, a conveyor belt, a cutter, a filter screen, a vibrating screen, and a conveying auger. When harvesting, the rice straw is transported to the threshing chamber by the conveyor belt. Inside, the rotating motion of the rice stalk is driven by the tooth plate of the roller and the impact of the cutter is blocked to achieve the effect of separating the rice stalk from the grain and crushing the rice stalk. The device outputs the grains to complete the threshing work. The cutters in the threshing part are vulnerable parts and often need to be maintained and replaced. However, the cutters of the thresher are currently figure 1 , figure 2 Shown basically is that triangular blade 1 is mainly installed on threshing cylinder 2, and t...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a semi-feeding combine harvester drum mower, which can solve the problems of troublesome replacement of the broken grass cutter in the threshing part of the existing semi-feeding harvester, easy grass entanglement and potential safety hazards. And it can make the maintenance of the cutter easier
