Novel grain corn combine harvester

Abstract

The invention discloses a novel grain corn combine harvester. The harvester comprises a driving control system, a transmission system, a traveling system, a header unit and a threshing unit, wherein the corn header unit is arranged at the front end of a harvester body, the threshing unit is arranged at the back end of the header unit and connected with the header unit through an elevating bridge, a collecting box and a grain recovery box are arranged on the threshing unit, and a straw returning device is arranged at the tail of the harvester body. The harvester is simple in structure, reliable in performance, high in threshing efficiency and capable of well applicable to threshing of corn cobs and completely separating corn grains on the corn cobs, so that the phenomenon that the corn cobs are blocked when moving forwards is prevented, the threshing efficiency is greatly improved, corn cobs can be recovered and utilized, the resource utilization rate is increased, full automation and systematization of corn harvesting are realized, and the harvester is clear in classification and high in efficiency.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a novel grain corn combine harvester. Background technique [0002] The current grain and corn combine harvester adopts the threshing and cleaning principle of "wheat harvester", which has a complex structure, a large whole machine, serious vibration, high failure rate, inconvenient installation and maintenance, and poor maneuverability. The collaborative operation effect between the header units is poor, and the degree of automation is low. In addition, its threshing unit is not very suitable for threshing corn on the cob. For corn with high moisture content, the corn kernels on the corn cob cannot be completely detached, and there will still be corn kernels left on the corn cob, which cannot be threshed normally. The cob often gets stuck as it moves forward and is extremely prone to clogging, resulting in inefficient threshing. Moreover, the corncob...

[0002] The current grain corn combine harvester adopts the threshing and cleaning principle of the "wheat harvester". The cooperative operation effect between the harvesting units is poor, and the degree of automation is low

In addition, its threshing unit is not suitable for threshing corn cobs. For corn with high moisture content, the corn kernels on the corn cobs cannot be completely separated, and corn kernels will still remain 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

Moreover, the threshed corncobs cannot be recycled and are thrown on the ground, wasting resources
