Anti-winding cotton stalk pulling roller

Abstract

The invention discloses an anti-winding cotton stalk pulling roller. The anti-winding cotton stalk pulling roller comprises a stalk pulling device, a stalk retreating device and a cutting device, wherein the stalk pulling device comprises a stalk pulling roller, a stalk pulling toothed plate, a walking groove, a guide rail, a shaft sleeve, a fixed guide seat, a transmission chain wheel and an endcover; the stalk retreating device comprises a stalk retreating plate, a connecting rod, a stalk retreating roller and a disc cam; and the cutting device comprises a cylindrical cam, a driven part, asupporting seat and a supporting shaft. The stalk pulling device is used for pulling out cotton stalks in the ground from the field and conveying the cotton stalks to the rear upper side; the stalk retreating device is used for rapidly separating the pulled-out cotton stalks from the stalk pulling toothed plate and enabling the cotton stalks to be poured backwards; and the cutting device is used for cutting off weeds, cotton stalk barks and the like which are wound on the stalk pulling device. According to the anti-winding cotton stalk pulling roller disclosed by the invention, the stalk retreating device is used so that the stalk pulling device can be prevented from being blocked; the cutting device is used so that the weeds, the cotton stalk barks and the like can be prevented from beingwound on the stalk pulling device; and in conclusion, the working efficiency and the cotton stalk thorough pulling rate can be improved by the anti-winding cotton stalk pulling roller.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an anti-winding cotton stalk pulling roller. Background technique [0002] As a renewable resource, cotton stalk has huge economic, social and ecological benefits. At present, there are mainly two methods of harvesting cotton stalks, manual and mechanical. Manual harvesting is labor-intensive and low in efficiency, so mechanical harvesting of cotton stalks is a commonly used method. However, the existing cotton stalk harvesting machinery, especially the horizontal cotton stalk removal machinery, has the problem that weeds, cotton stalk bark, etc. are entangled with rotating parts, and the cotton stalks are not easy to separate from the removal parts, resulting in a relatively low cotton stalk removal rate and work efficiency . Contents of the invention [0003] The purpose of the present invention is to provide an anti-tangle cotton stalk pulling roller to solv...
