Cutting knife structure of harvester and harvester

Abstract

The invention relates to a cutting knife structure of a harvester. The cutting knife structure comprises a cutting knife sliding groove frame provided with a sliding groove, a sliding block matched with the sliding groove, a cutting knife arranged on the sliding block, a connecting rod with one end connected with the sliding block, an eccentric counterweight assembly connected with the other end of the connecting rod and a driving device for driving the eccentric counterweight assembly to swing, so that the eccentric counterweight assembly drives the sliding block to do reciprocating motion inthe sliding groove, and the cutting knife cuts off crop stalks. The invention provides the harvester applying the cutting knife structure. According to cutting knife structure of the harvester and the harvester, stable cutting can be effectively achieved, the impact load of the cutting knife in the cutting process is reduced, meanwhile, the power transmission mode is changed, the transmission path is compressed, and the stability and reliability of power transmission are effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a harvester cutter structure and a harvester. Background technique [0002] A harvester is a machine that harvests crops in one piece. It completes harvesting and threshing at one time, and gathers the grains into the storage bin, and then transports the grains to the transport vehicle through the conveyor belt. [0003] With the continuous development of my country's agricultural technology level, the degree of agricultural mechanization in our country has been continuously improved. However, in order to meet the harvesting requirements when the harvester is harvesting, the trajectory and route of each moving part are complicated. Among them, the cutter device of the harvester is mainly used for cutting the stalks or roots of crops. In the design scheme of the existing harvester, the transmission of the cutter device of the harvester adopts a mechanical transmissi...

[0003] With the continuous development of my country's agricultural technology level, the degree of agricultural mechanization in my country has been continuously improved. However, in order to meet the harvesting requirements of the harvester, the trajectory and route of each moving part are complicated.

Among them, the cutter device of the harvester is mainly used for cutting the stems or roots of the crops. In the design scheme of the existing harvester, the transmission of the cutter device of the harvester adopts a mechanical transmission mode. This transmission mode is noisy. The transmission path is too long and there are many wearing parts
