Improved household double-drum corn threshing machine

Abstract

The invention discloses an improved household double-drum corn threshing machine, which comprises a threshing machine box, the middle part of the right wall of the threshing machine box is bent toward the inside of the threshing machine box, and the upper end of the left side wall of the threshing machine box is connected with a feeding channel. The front rocker arm drives the feed baffle to reciprocate up and down, and the rear sliding arm reciprocates up and down on the fixed frame synchronously, so that the corn enters the threshing machine quantitatively, without the need for staff to operate. After entering the threshing drum, it first passes through the upper corn threshing drum. Threshing, and then enter the lower corn threshing drum to improve the threshing effect. The threshing motor is driven by the transmission chain to drive the shaft to rotate at high speed. The crushed corn kernels are screened out, and the corn kernels are subjected to deslagging treatment without additional slag removal treatment, which improves work efficiency, and the blower accelerates the separation of corn kernels and crushed corn dregs.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an improved household double-drum corn thresher. Background technique [0002] A thresher is a post-harvest machine for agricultural products, which refers to a machine that can separate the grain of the crop from the stalk, and mainly refers to the harvesting machine of the grain crop. According to the different crops, there are different types of threshers, including rice threshers, corn threshers, and threshers. Existing corn threshers usually only have one disengagement drum in the disengagement chamber, and the disengagement drum rotates under the drive of the motor during threshing. Due to the limited contact area between the threshing drum and the side of the threshing chamber, the number of corn cobs to be threshed at the same time is relatively small. Small threshing efficiency is low, and under the high-speed drive of the corn threshing device motor, the...

Problems solved by technology

Existing corn threshers usually only have one disengagement drum in the disengagement chamber, and the disengagement drum rotates under the drive of the motor during threshing. Due to the limited contact area between the threshing drum and the side of the threshing chamber, the number of corn cobs to be threshed at the same time is relatively small. Small threshing efficiency is low, and under the high-speed drive of the corn threshing device motor, the corn hits the threshing drum and threshes, which will inevitably crush a small part of the corn cob, which will cause a large amount of corn to be threshed. Slag, the existing corn thresher does not have a slag removal device, so it is necessary to additionally remove the slag from the threshed corn kernels, which increases the process and leads to low work efficiency. Therefore, we provide an improved household double-drum corn thresher
