Grass discharge and anti-blocking device for harvester and its working method

Abstract

The invention discloses a grass discharging anti-blocking device for a harvester and a working method thereof, and belongs to the technical field of agricultural machines. The grass discharging anti-blocking device structurally comprises a transmission pipe shaft. A plurality of poking teeth are installed on the transmission pipe shaft. The poking teeth are spirally distributed in the axis direction of the transmission pipe shaft and do reciprocating motion in the axis direction of the transmission pipe shaft while the transmission pipe shaft rotates. The transmission pipe shaft drives the poking teeth to rotate and is provided with a connecting device connected with the harvester. The transmission pipe shaft drives the poking teeth to rotate and do the reciprocating motion in the axis direction of the transmission pipe shaft, the spreading area is increased, the poking teeth poke materials at a grass discharging opening out and spread the materials, the situation that the materials accumulate on the same point of the grass discharging opening and block the grass discharging opening is effectively avoided, and smooth operation of product quality detection work is guaranteed.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a grass-discharging and anti-clogging device for a harvester and a working method thereof. Background technique [0002] In recent years, with the acceleration of the process of agricultural mechanization in my country and the continuous increase in market demand, the number and scale of enterprises engaged in the production of harvesting machinery have also increased rapidly. Wheat harvesters are agricultural machinery products that are promoted and subsidized by the state. It is an important link. In order to avoid the impact of the inspection link on the mechanical performance as much as possible and objectively reflect the product quality status, in the face of complex external conditions, continuous improvement of the inspection device is a necessary condition to ensure the smooth progress of the inspection work and the quality of the work.

AI Technical Summary

Problems solved by technology

[0003] Wheat harvesters have various types of grass discharge. Among them, spiral grass discharge occupies an important proportion in domestic machines. Usually, during field performance tests, the collection of wheat straw often causes straw accumulation at the grass discharge outlet, resulting in blockage of the grass discharge spiral. Not only The cleaning work is labor-intensive and cumbersome, and if the cleaning is not timely, it will seriously hinder the development of the inspection work, and even affect the normal operation of the machine.
