Vertical-shaft gang-tool corn straw header mechanism

Abstract

The invention discloses a vertical-shaft gang-tool corn straw header mechanism. The vertical-shaft gang-tool corn straw header mechanism consists of a grain lifter, two groups of vertical-shaft movable-tool mechanisms, two groups of comb-tooth fixed-tool mechanisms, two groups of transmissions, a spiral conveying mechanism, a conveying fan and a power conveying mechanism, wherein each mechanism is connected to a frame through bolts; the two groups of transmissions are connected in series through a spindle; a transmission belt pulley I is arranged at the lower end of each group of transmissions, and is connected with the vertical-shaft movable-tool mechanisms; the two groups of vertical-shaft movable-tool mechanisms are arranged symmetrically; the working axes of each group of vertical-shaft movable-tool mechanisms are coincided with symmetric axes of each group of comb-tooth fixed-tool mechanisms respectively. During working, corn straw is cut and smashed under the support of the grain lifter under the coaction of the vertical-shaft movable-tool mechanisms and the comb-tooth fixed-tool mechanisms, the smashed straw is thrown out under the actions of the spiral conveying mechanism and the conveying fan, and the thrown materials can be recycled for green and yellow corn silage and shaping and can be directly returned to field.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a vertical shaft group knife-type header mechanism for standing or semi-lodging corn stalk harvesting after ear picking, and is especially suitable for straw silage, yellow storage, forming processing and straw returning operations. Background technique [0002] At present, most of the existing corn stalk cutting platforms in China are horizontal shaft mechanisms, and the bottom adopts a disc cutter. After the root of the corn stalk is cut off, it is transported to the crushing device for crushing through the clamping device and the lifting device. , complex structure, large power consumption, high cost, poor economy, not suitable for the development of rural areas in our country, so there is an urgent need for a simple structure, economical and applicable corn stalk harvesting mechanism at this stage. Contents of the invention [0003] In order to ov...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the disadvantages of the existing corn stalk cutting platform mechanism, such as complex structure, large power consumption and high cost, the present invention provides a vertical shaft group knife type corn stalk cutting platform mechanism, in which the vertical shaft group knife and comb-teeth fixed knife are reasonable Matching, integrating grabbing, feeding, and cutting. The crushed corn stalks are transported through the conveying device, and can be collected for straw green storage, yellow storage, forming processing, and can also be returned directly to the field.
