Problems solved by technology

[0002] The current grain corn combine harvester adopts the threshing and cleaning principle of the wheat harvester. Its structure is complex, the whole machine is huge, the vibration is serious, the failure rate is high, the installation and maintenance are inconvenient, and the maneuverability is poor.
Its threshing drum device is not suitable for threshing corn cobs. For corn with high moisture content, the corn kernels on the corn cobs cannot be completely threshed, and there will still be corn kernels on the corn cobs, which cannot be threshed normally. The corn cobs are often stuck during the forward movement and are easily blocked, resulting in low threshing efficiency

Abstract

The invention discloses a corn threshing roller. The threshing roller device comprises a threshing roller and a cylindrical sieving body, wherein the threshing roller comprises a roller shaft, a spiral guiding plate is fixedly arranged at one end of the roller shaft, and a centrifugal throwing and sending plate is fixedly arranged at the other end of the roller shaft; a set of threshing hammers are uniformly distributed on the roller shaft, each threshing hammer comprises a connecting rod and a spherical hammer body fixedly arranged at the tail end of the connecting rod, and the connecting rods are fixedly connected with the roller shaft; the cylindrical sieving body sleeves the threshing roller, a solid plate is arranged at the upper half part of the cylindrical sieving body, and a sieveis arranged at the lower half part of the cylindrical sieving body. The corn threshing roller is simple in structure, reliable in performance, high in threshing efficiency, and capable of well adapting to threshing of corncobs, the corncobs can be completely threshed, and the phenomenon that the corn threshing roller is stuck and blocked in the forward moving process of the corncobs can be prevented.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a corn threshing cylinder. Background technique [0002] The current grain corn combine harvester adopts the threshing and cleaning principle of the wheat harvester. Its structure is complex, the whole machine is huge, the vibration is serious, the failure rate is high, the installation and maintenance are inconvenient, and the maneuverability is poor. Its threshing drum device is not suitable for threshing corn cobs. For corn with high moisture content, the corn kernels on the corn cobs cannot be completely threshed, and there will still be corn kernels on the corn cobs, which cannot be threshed normally. The corn cobs are often stuck in the process of moving forward, which is very easy to block, resulting in low threshing efficiency. Contents of the invention [0003] The object of the present invention is to provide a corn threshing drum with simp...
