Portable handheld cotton picker

Abstract

A portable handheld cotton picker is disclosed, wherein an open cotton-picking opening is disposed at the front end of a shell, and the bottom of the front end of the shell is opened to compose a cotton-falling opening. The portable handheld cotton picker is characterized in that a groove is disposed on the circumferential outer edge of a driven convey belt wheel of a picking device disposed at the cotton-picking opening at the front end of the shell; strong magnets equally distributed on a circumference are disposed in the groove; a drive cotton-picking convey belt wheel is disposed on the middle part of the shell and installed with a cotton-picking convey belt bulged transmission wheel disposed between a front wheel and a rear wheel and protruding the axes of the two wheels in a triangular layout; a cotton-picking convey belt is coaxially covered on the outer edge ends of the driven cotton-picking convey belt wheel, the convey belt bulged transmission wheel and the drive cotton-picking convey belt wheel in a surrounding way; cotton-picking hook teeth and cotton-unloading devices are uniformly distributed on the outer edge part of the cotton-picking convey belt; and strong magnet pieces are disposed on the middle part of a cotton-unloading spring piece as well as realize closure and separation with the strong magnets equally distributed in the groove of the driven cotton-picking convey belt wheel via the rotating operation of the driven cotton-picking convey belt wheel. The portable handheld cotton picker disclosed by the invention is simple in structure and scientific in design; and the cotton-picking hook teeth in a cotton-picking chamber and the cotton-unloading devices are automatically combined and separated.

Description

Technical field [0001] The invention relates to a portable hand-held cotton picker, in particular to a hand-held high-speed cotton picker. Background technique [0002] my country is a big cotton producing country. The traditional cotton picking is done manually. The efficiency of manual picking is low, the labor intensity is high, and the overall cost of cotton production is relatively high. Especially in recent years, it has become difficult to recruit flower pickers. A variety of cotton picking machines have appeared on the market, among which, the hand-held picking machine includes a tubular housing with a motor in the rear, and sprockets are arranged in parallel at the front and rear ends of the housing, and the cotton picking chain passes through the front and rear chains. The wheels are connected together, and the driving device drives the cotton picking chain to rotate by driving the cotton picking sprocket to carry out cotton picking. After the hand-held cotton picke...

[0002] my country is a large cotton-producing country. Traditional cotton picking is done manually. The efficiency of manual picking is low, the labor intensity is high, and the overall cost of cotton production is relatively high. Especially in recent years, it has become difficult to recruit flower pickers, and the market A variety of cotton picking machines have appeared on the market, among which, the hand-held picking machine includes a tubular housing with a motor in its rear, and sprockets are arranged in parallel at the front and rear ends of the housing, and the cotton picking chain passes through the front and rear chains. The wheels are connected together, and the driving device drives the cotton picking chain to rotate by driving the cotton picking sprocket to carry out cotton picking

After the hand-held cotton picker works for a long time, the cotton will be entangled on the front sprocket and the rear sprocket, which will cause the chain to be tightened, the speed will slow down, the load will increase, and the motor will heat up, causing the motor coil to burn and cannot work normally.
