Grain discharging mechanism of harvester

Abstract

The invention discloses a grain discharging mechanism. The grain discharging mechanism comprises a horizontal stranding cage located in a threshing bin, a grain discharging barrel and a grain lifting mechanism located in the grain discharging barrel, wherein the horizontal stranding cage comprises a transmission shaft and a blade connected with the transmission shaft, and a first chain wheel is arranged at the end, close to the grain lifting mechanism, of the transmission shaft; the grain lifting mechanism comprises a grain scraping chain plate and a second chain wheel, the second chain wheel is installed at the outlet end of the grain discharging barrel, the grain scraping chain plate is meshed with the first chain wheel and the second chain wheel, and a plurality of grain scraping plates are distributed on the outer surface of the grain scraping chain plate at intervals. The grain discharging mechanism has high discharging efficiency and the horizontal stranding cage can be prevented from being blocked.

Description

technical field [0001] The invention relates to parts of a harvester, more specifically to a grain discharge mechanism of a harvester. Background technique [0002] With the development of society, harvesters are widely used in agriculture. After the harvester threshes the grain, it is preliminarily screened by the screening mechanism and enters the grain bin of the harvester, and then the grain is discharged through the grain discharge mechanism, and the discharged grain is collected and transported to the designated place. [0003] The existing grain discharge mechanism includes a horizontal cage and a vertical cage, and through the cooperation of the horizontal cage and the vertical cage, the discharge of the grain is realized. The existing grain discharge mechanism easily causes poor grain flow and blocks the horizontal cage. In order to avoid the blockage of the horizontal winch cage, some harvesters are equipped with an umbrella-shaped winch cover plate on the horizo...

Problems solved by technology

The existing grain discharge mechanism may easily cause poor grain flow and block the horizontal cage

In order to avoid the blockage of the horizontal winch cage, some harvesters are equipped with an umbrella-shaped winch cover plate on the horizontal winch cage, and an adjustment plate is also provided on the winch cage plate to prevent the horizontal winch cage from being blocked, and the grain of this structure is discharged. The structure of the mechanism is complicated and the use is complicated, especially not suitable for application on small semi-feeding harvesters
