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

A cotton picking needle and a mechanical cotton picking device equipped with the cotton picking needle technical field The invention relates to a cotton picking needle and a mechanical cotton picking device equipped with the cotton picking needle. Background technique In order to solve the problem of large number of workers and high labor intensity during the cotton picking season, people have developed various mechanical cotton picking devices. Large and high cost, the ordinary cotton growers are unable to purchase due to their limited economic capacity, and still stay at the stage of manual cotton picking, which affects the large-scale promotion of mechanical cotton picking devices. In my country, there is a large-scale cotton picking machine imported from the United States. Cotton picking needles are installed on the drum. The cotton picking needles are driven by the hydraulic mechanism in the drum to rotate and rotate with the drum. In order to improve the cotton pick...
