Cotton picking needle and mechanical cotton picking device provided with same

Abstract

The invention aims at providing a cotton picking needle and a mechanical cotton picking device provided with the cotton picking needle. The axial periphery of the body of the cotton picking needle is uniformly provided with a plurality of grooves at intervals, an axial convex edge between two adjacent grooves is uniformly provided with triangle cotton picking teeth which are arranged from the needle head to the needle tail at intervals, and the convex sharp corners of the cotton picking teeth are all close to the needle head. The cotton picking needle provided by the invention is arranged on a cotton picking needle base, the cotton picking needle base moves from bottom to top along a driving belt arranged in the shell of a cotton picking device, meanwhile the cotton picking needle rotates when being driven by a center shaft in the cotton picking needle base to wind cotton fibers onto the cotton picking needle, and finally the cotton fibers are easily removed by a cotton carding loop sheathed on the cotton picking needle in sliding fit and are sucked by a cotton sucking port arranged behind the upper part of the cotton picking device. The invention is reasonable in structure, the operation is smooth, the cotton picking rate is high, and the market prospect is wide.

Description

Technical field [0001] The invention relates to a cotton picking needle and a mechanical cotton picking device equipped with the cotton picking needle. Background technique [0002] In order to solve the problem of the large number of workers in the cotton picking season and the high labor intensity of the workers, various mechanical cotton picking devices have been developed. Although these devices have high cotton picking efficiency and large cotton picking capacity, they also have complex structures and large volumes. Due to the large and high cost, ordinary cotton growers are unable to buy due to their limited economic affordability. They are still at the stage of manual cotton picking, which affects the large-scale promotion of mechanical cotton picking devices. [0003] In our country, there is a large cotton picker imported from the United States. The cotton picking needle is set on the drum. The cotton picking needle is driven by the hydraulic mechanism in the drum to rotat...

Problems solved by technology

Its disadvantage is that the equipment is not only expensive, but also the collected cotton fibers are entangled on the cotton picking needles, which is very difficult to take off the cotton, and it is very inconvenient to use
