Multifunctional drawer type header for grain combine harvester

Abstract

The invention relates to a multifunctional drawer type header for a grain combine harvester. Each of left and right sides of the header is provided with a drawer type rear end and a drawer type front end, and left and right ends of a conveying device are connected with the left and right drawer type rear ends respectively. Left and right ends of a cutting device are connected with the left and right drawer type front ends respectively, and a divider is connected to each drawer type front end. The drawer type rear ends and the drawer type front ends form drawer type connection through inner drawer type slide rails and outer drawer type slide rails, and extension and retraction of the left and right drawer type front ends are controlled by header depth regulation hydraulic cylinders. Rear ends of left and right reel frames are rotatably connected to a shell of the header, left and right ends of an eccentric reel are connected with the left and right reel frames respectively, and the position of the eccentric reel is adjusted through a reel horizontal position adjusting hydraulic cylinder and a reel vertical position adjusting hydraulic cylinder. The multifunctional drawer type header is applicable to harvesting of crops different in type and height, quick switching of various crop harvesting modes is realized, harvesting loss is reduced, and utilization rate of the header is increased remarkably.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, in particular to a multifunctional drawer-type header for a grain combine harvester. Background technique [0002] In recent years, with the continuous increase of the country's investment in agricultural production, most of my country's main food crops such as corn, wheat, and rice have achieved mechanized harvesting, but the penetration rate of mechanized harvesting of soybeans and rapeseed is low. The main reason is that domestic Advanced soybean and rapeseed combine harvesters have single functions, low product utilization, low efficiency, few varieties, small selection options, and poor economic benefits. However, when soybeans and rapeseed are harvested by ordinary rice and wheat combine harvesters, due to the different growth forms of crops, large harvest losses will occur, and most of the losses are caused by poor adaptability of headers. Grain multifunctional headers can h...

AI Technical Summary

Problems solved by technology

Therefore, the functions to be realized by the multifunctional header are complicated, and the corresponding structural forms and adjustment processes are also relatively complicated. There are few complete researches on this, and there are few corresponding inventions.

Generally speaking, the existing headers of grain combine harvesters have problems such as single function, large harvest loss, and complicated switching between different harvesting modes.
