Description

Technical Field

[0001] The utility model relates to the technical field of cotton pickers, and more specifically, to a picking shaft for a cotton picker. Background Art

[0002] With the development of modern industrial technology, cotton picking has gradually evolved from traditional manual picking to picking with cotton pickers. When picking cotton, the cotton picker uses a driving device to drive the picking shaft to rotate, so that the cotton is entangled on the picking teeth of the picking shaft, and then the cotton stripping mechanism is used to remove the entangled cotton, so as to achieve the effect of efficient cotton picking.

[0003] However, since the top teeth of the picking shaft were not reinforced, the top part of the picking shaft was severely worn after a period of use and the hook teeth became smooth, which further led to the failure of the cotton wool hook;

[0004] A Chinese patent with patent application number CN202121386331.5 discloses a picking shaft for a cotton picker. A first shaft sleeve ring is built into the top of the shaft sleeve, and a second shaft sleeve ring is built into the rear end of the shaft sleeve; a hexagonal wrench ring is provided in the middle of the outer wall of the shaft sleeve; the picking shaft is divided into three sides by the tapered shaft portion of the cotton picking shaft, and racks are arranged vertically on each side; 2-4 teeth at the top of the rack are reinforced teeth, and ordinary teeth are arranged at the back; the reinforced teeth and ordinary teeth constitute a structure in which one side of the tooth body is a tooth slope surface, and the oblique tip of the tooth body is a tooth hook, and the tooth hook is exposed on the front side of the tapered shaft groove. The improved technical solution realizes the durability of the cotton picking shaft, and through the designed tooth hook, it is easy to hook cotton wool during the cotton picking process, and it is convenient to remove cotton after the cotton picking shaft rotates at high speed;

[0005] However, it can be seen from the drawings in its specification that the shaft and gear of the picking shaft for the cotton picker are designed as an integrated whole, and the overall length is fixed, which makes it inconvenient to adjust the length according to usage needs. Moreover, when the picking end is worn out due to long-term use, it can only be replaced as a whole, and it is inconvenient to replace it individually, resulting in material loss and increased cost. Therefore, a picking shaft for a cotton picker is proposed. Utility Model Content
