Corn thresher

Abstract

The invention discloses a corn thresher. The corn thresher comprises a rack supporting body, a shell, a feeding funnel, a motor and a roller shaft, wherein a threshing roller is mounted on the rollershaft, and an arc grid dropping plate is mounted in the rack supporting body; an inclined plate body is mounted in the rack supporting body through bolts, one end of the inclined plate body is provided with a corn grain bin, and a discharge assembly is mounted on a transmission shaft; one end of the shell is provided with an arc-shaped baffle through a movable piece; one end of the rack support body is connected with a corn cob discharging bin, and the corn cob discharging bin is aligned with a feeding bin of a corn cob crusher. The upper end of the rack support body is provided with a fan, afan port of a fan pipe is positioned in the shell, and the shell is provided with a corn stigma discharge pipe. According to the corn thresher, corn threshing and corn cob crushing can be simultaneously achieved, corn grains can be prevented from being scattered on the ground, the threshing efficiency is high, threshing is carried out thoroughly, the yield of the corn grains can be increased, thephenomena of blockage or jamming are prevented, and electric energy is saved.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a corn thresher. Background technique [0002] Corn is a very important food crop, which can be used as food or feed, and is also one of the important industrial raw materials. Corn threshing still adopts relatively backward technology in most places in my country. Although various large and medium-sized corn threshers are used in some places for threshing, the production of these machines is not standardized, which is easy to cause the corn kernels to be broken, and often the threshing is not clean at one time, and it needs to be threshed several times, which seriously affects the production quality of corn. and production efficiency. The manual manual corn thresher has low productivity and is only suitable for small batch corn thresher production, which is time-consuming and labor-intensive. The electromechanical corn thresher has poor cleaning rate and low ef...

AI Technical Summary

Problems solved by technology

Although the threshing effect of this structure is relatively good, the corn thresher can only perform corn threshing, and the crushing of corn cobs needs to be operated separately, which is time-consuming and laborious, and is particularly inconvenient

[0006] To sum up, when the corn threshers in the prior art are threshing, it is easy to cause corn kernels to be broken, which reduces the yield of corn kernels, and after the threshing is completed, the corn kernels are directly discharged from the hopper, resulting in chaotic accumulation of corn kernels , scattered everywhere, and the corncobs are also scattered all over the place, which is not easy to clean up, and the corn silk is stuck in the thresher, which may easily cause the thresher to malfunction
