Combined corn thresher and threshing method thereof

Abstract

The invention provides a combined corn thresher which consists of a transverse threshing device and a longitudinal threshing device. The transverse threshing device and the longitudinal threshing device are in occlusion connection through a gear and a gear with a nail disk, wherein the transverse threshing device consists of a motor, a belt pulley, a cone gear, a rack, a transmission gear, the gear with the nail disk, a regulator bracket, a baffle, a spring, a regulating nut and a screw; and the longitudinal threshing device consists of a concave thresher, a threshing roller with spike teeth, roller threshing teeth, a regulating device, a transmission gear and a bearing support. In a threshing method disclosed by the invention, a transverse and longitudinal alternate threshing technology is adopted. The threshing method has good threshing effect and high efficiency. Corncobs are not crushed. The threshing method is suitable for vast rural market.

Description

technical field [0001] The invention relates to a combined corn thresher and a threshing method thereof, belonging to the technical field of agricultural machinery and equipment processing. Background technique [0002] Existing corn threshers are divided into large, medium, and small sizes. The horizontal threshing method is adopted in the threshing process, which can only be threshed once in one direction. In this way, it is easy to break the corn cob when the threshing is not complete, because it is a one-time threshing process. , The gap between the threshing parts must be adjusted according to the size of the corn. If the gap is too large, the threshing effect cannot be achieved, and if the gap is too small, the corn cob will be broken. After the corn cob is broken, the corn kernels cannot be threshed. This will require a lot of manpower to clean without threshing In order to overcome the defects of the above-mentioned threshing technology, a combined corn thresher is s...

Problems solved by technology

[0002] Existing corn threshers are divided into large, medium, and small sizes. They all adopt the horizontal threshing method in threshing, and can only thresh once in one direction. In this way, it is easy to break the corn cob when the threshing is not complete, because it is a one-time threshing process. , The gap between the threshing parts must be adjusted according to the size of the corn. If the gap is too large, the threshing effect cannot be achieved, and if the gap is too small, the corn cob will be broken. After the corn cob is broken, the corn kernels cannot be threshed. This will require a lot of manpower to clean without threshing In order to overcome the defects of the above-mentioned threshing technology, a combined corn thresher is specially designed, which does not need to be completely threshed in the first horizontal threshing, which reduces the motor load and does not break the corn cob. The first After the first threshing, the drive gear on the second threshing device is driven by the nailed disk gear on the threshing device to carry out the second threshing
