Cotton separation device of cotton picking machine

Abstract

The invention discloses a cotton separation device of a cotton picking machine, which separates cotton while picking and realizes a good separation effect. Particularly, when collecting the cotton with dew, a shell and a cotton conveying pipe are not blocked easily. The device comprises a shell (9), wherein a belt (10) driven by power is mounted in the shell (9); a picking needle (6) is mounted on the belt (10); and one end of the shell (9) is a picking port. The device is characterized in that a cotton conveying pipe (8) is mounted at the picking port; a cotton separation plate is mounted in the cotton conveying pipe (8) and separates the cotton picked by the picking needle (6) from the picking needle (6); and meanwhile, according to the moving direction of the picking needle (6), the shell (9) is also provided with an auxiliary cotton separation plate behind the cotton separation plate. The device disclosed by the invention has a simple structure; the design of the whole machine is reasonable, and the device is convenient to use; the separation effect of the picking needle and the cotton is good; the cotton conveying distance is short; and particularly, when picking the cotton with dew, the separation effect is good, the shell and the cotton conveying pipe are not easily blocked, the working efficiency is greatly improved, and the device has better practicability.

Description

technical field [0001] The invention relates to a cotton field machine, in particular to a cotton picking machine, in particular to a cotton removing device for a cotton picking machine. Background technique [0002] my country is a big cotton planting country, and its cotton picking has two ways of manual and mechanical. The quality of hand-picked cotton is high, but the first is low production efficiency, the second is labor-intensive, and the third is that it is easy to be pricked by the opened cotton bolls during the picking process, causing physical damage. Large-scale cotton pickers can pick cotton fast, but the picked cotton cannot be graded, contains a lot of impurities, and the cotton cannot be completely harvested. Moreover, the requirements for cotton planting and management models are strict, and the equipment structure is complicated, expensive, and has a low failure rate. High, unacceptable for ordinary cotton farmers. [0003] At present, there are also many...

Problems solved by technology

[0006] Due to the long transportation distance of the collected cotton, after a period of use, the cotton will inevitably wind up and accumulate on the nail teeth, collection wheels or other components, so as to block the shell and cotton delivery pipe, especially when collecting dewy cotton , it is easier to block
