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.

Embodiment Construction

[0029] The present invention will be further described below in conjunction with accompanying drawing of description and specific embodiment:

[0030] Such as figure 1 As shown, the harvester grass discharge and anti-blocking device includes a transmission tube shaft 4, and three shifting teeth 3 are installed on the transmission tube shaft 4, and the shifting teeth 3 are distributed in a spiral shape along the axial direction of the transmission tube shaft 4, as image 3 As shown, the three shifting teeth 3 circle around the transmission tube shaft 4, and the angle between them is 60°, forming a uniform distribution in the circumferential direction of the transmission tube shaft 4, while the transmission tube shaft 4 rotates on its axis The direction is reciprocating, and the transmission tube shaft 4 drives the shifting gear 3 to move, and the transmission tube shaft 4 is provided with a connecting device connected with the harvester.

[0031] The shifting tooth 3 is rod-sh...
