A kind of corn thresher

Abstract

The invention provides a corn thresher, which belongs to the technical field of agricultural machinery and improves the efficiency and effect of corn thresher. The corn threshing machine, including the frame, is characterized in that the corn threshing machine includes a screw feeding mechanism, a conveyor belt feeding mechanism, a rotary threshing mechanism and a transmission mechanism; the corn cobs are transported to the rotary threshing mechanism through the screw feeding mechanism and the conveyor belt feeding mechanism In the threshing mechanism, the corn cobs are threshed under the action of the stirring rod and the stirring grid, and the threshed corn kernels and impurities are separated and collected. The invention has the advantages of high threshing efficiency, good threshing effect and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery and relates to a corn thresher. Background technique [0002] For corn threshing, there are traditional manual threshing and machine threshing. Manual threshing is to use a screwdriver to push down a few rows along the corn kernels, and then push a few rows, and then use hands or two corn cobs to rub against each other. The efficiency is low, and the machine Compared with manual threshing, the efficiency of threshing has been greatly improved. Chinese patent (application number: CN201020113956.X) discloses a corn thresher, which includes a frame, a threshing roller, a screen, an outer cover, etc., and relies on the threshing teeth, connecting bars and columns on the threshing roller to apply pressure to the corn cob respectively. , imitating manpower to knead the corn cobs for threshing. After the corn cobs are harvested, they are usually temporarily piled up on the ground for stor...

Problems solved by technology

[0002] For corn threshing, there are traditional manual threshing and machine threshing. Manual threshing is to use a screwdriver to push down a few rows along the corn kernels, and then push a few rows, and then use hands or two corn cobs to rub against each other. The efficiency is low, and the machine Compared with manual threshing, the efficiency of threshing has been greatly improved

Chinese patent (application number: CN201020113956.X) discloses a corn thresher, which includes a frame, a threshing roller, a screen, an outer cover, etc., and relies on the threshing teeth, connecting bars and columns on the threshing roller to apply pressure to the corn cob respectively. , imitating manpower to knead the corn cobs for threshing. After the corn cobs are harvested, they are usually temporarily piled up on the ground for storage. When the thresher is threshing, it is necessary to manually pour the corn cobs to be threshed into the machine, and the degree of automation is not enough. High, and when the threshing teeth in the device are threshing, it is easy to scratch the corn kernels

Chinese patent (application number: CN201820552359.3) discloses a simple and convenient corn thresher device for agriculture, including a corn threshing chamber, the surface of the rotating shaft is fixedly connected with rotating teeth, and the inner wall of the corn threshing chamber is fixedly connected with fixed teeth. Under the rotation of the rotating shaft, the rotating teeth interact with the fixed teeth on the wall of the threshing chamber to perform threshing. The disadvantages are: first, when threshing, it is still necessary to manually pour the corn cobs into the threshing chamber, which is laborious. And it is not convenient enough. Secondly, the fixed teeth that are separated from the inner wall have a sharp structure, which is easy to scratch the corn kernels. Thirdly, when the corn and impurities are separated by the fan in this device, there is no independent separation channel, which is easy to mix together again, affecting seperate effect
