Abstract

The invention discloses a long-stroke low-damage corn niblet threshing device and method. The device comprises a transmission part, a feeding part and a threshing and separating part; the feeding partcomprises a feeding roller, and the feeding roller is provided with feeding spike teeth and spiral blades located at the right sides of the feeding spike teeth; the threshing part comprises a threshing roller, threshing spike teeth are uniformly distributed on the threshing roller, and the threshing roller is not provided with a baffle and a separating plate; a device body is provided with an impurity discharging opening located at the right end of the threshing roller, the corn threshing stroke can be effectively increased, and the corn niblet pulverizing rate is lowered; the transmission part transmits power to the feeding roller and the threshing roller, and thus the feeding roller and the threshing roller are driven to rotate. Compared with a traditional feeding roller, a section of spiral blades are added on the feeding roller, and the threshing stroke can be increased; meanwhile, the threshing roller is not provided with the baffle and the separating plate, corn niblet damage can be lowered, the thorough threshing rate is increased, and the threshing stroke is greatly increased.

Description

technical field

[0001] The invention relates to the field of agricultural product harvesting machinery, in particular to a long-stroke and low-damage corn grain threshing device and method. Background technique

[0002] During the corn harvest season in the Huanghuaihai area, the accumulated temperature is not high and the temperature difference between day and night is large, so the growing corn cannot be dehydrated quickly, which directly leads to the problem of high broken rate of grain mechanized harvesting.

[0003] The existing corn grain harvester cannot solve the problem of high corn grain breakage rate, which hinders the development of corn grain mechanized harvesting technology in the Huanghuaihai area.

[0004] In addition, corn harvesting machinery is based on the wheat combine harvester, and harvests corn grains by changing headers, threshing drums, etc. The length of the threshing drum is greatly limited, which directly affects its threshing process and cannot ...
