Combine harvester threshing cylinder assembly

Abstract

The invention discloses a combine harvester threshing cylinder assembly. The combine harvester threshing cylinder assembly comprises a front assembly, a main shaft, a front main shaft connecting plate, a middle main shaft connecting plate, a rear main shaft connecting plate, installation holes, connecting rods, grain beating teeth, installation sheets, front installation seats, rear installation seats and bolts. The front assembly is fixedly installed on the front main shaft connecting plate, the front end of the main shaft is fixedly installed in the installation hole of the front assembly, the rear end of the main shaft is fixedly installed in the center hole of the rear main shaft connecting plate, the connecting rods are radially provided with the plurality of grain beating teeth, the front installation seats are fixedly installed in clamping grooves at the front ends of the connecting rods, the rear installation seats are fixedly installed in camping grooves at the rear ends of the connecting rods, the connecting rods are fixedly provided with the installation sheets, the front installation seats are installed at the front main shaft connecting plate, the rear installation seats are installed at the rear main shaft connecting plate, and the middle main shaft connecting plate is installed on the installation sheets of the connecting rods. The combine harvester threshing cylinder assembly is simple in structure, convenient to install and maintain and low in cost; and the combine harvester threshing cylinder assembly is provided with the six connecting rods, the disengagement effect is good, and the disengagement efficiency is high.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to a harvester, in particular to a combine harvester threshing cylinder assembly. Background technique [0002] A harvester is an integrated machine for harvesting crops. Harvesting, threshing and concentrating the grains into the storage bin at one time, and then transporting the grains to the transport vehicle through the conveyor belt. Manual harvesting can also be used to spread the stalks of rice, wheat and other crops in the field, and then use grain harvesting machinery to pick up and threshing. The harvesting of grains and stalks of cereal crops such as rice and wheat. Among them, the threshing drum is an important part of the harvesting machinery, and together with the concave screen, it plays the role of separating the grain from the stem. [0003] In practical application, due to the operating environment, crop varieties and individual differences, after the machine has been ...

AI Technical Summary

Problems solved by technology

[0003] In practical application, due to the operating environment, crop varieties and individual differences, after the machine has been used for a period of time, due to the wear of the batting teeth on the batting teeth and the deformation of the concave screen, the gap between the tip of the teeth and the concave screen will The gap between threshing becomes larger, which leads to the phenomenon of unclean threshing and discharge of stems and grass entrained in grains, resulting in excessive harvest loss rate

Usually, the cleaning rate is improved by adjusting the rotation speed of the threshing drum or the clearance of the concave plate sieve, but this adjustment is likely to cause damage to the high-maturity, plump and easy-to-drop grains under repeated blows
