High-efficiency and low-trash content cotton picker

Abstract

The invention discloses a high-efficiency and low-trash content cotton picker, which comprises a shell, a cotton clamping and conveying assembly, a driving assembly and a separating tube; the shell comprises a tubular shell and a handle; the cotton clamping and conveying assembly comprises an upper conveyer belt, a lower conveyer belt, a left conveyer belt and a right conveyer belt, the front end and rear end of each conveyer belt are respectively supported by a driven roller and a driving roller, bevel gears are arranged at both ends of the driving roller, and the neighboring driving rollers are engaged through the bevel gears; the driving assembly comprises a motor and a speed reducer, and the speed reducer is transmissively connected with one of the driving roller in the cotton clamping and conveying assembly through a transmission part; the separating tube is used for separating cotton from the conveyer belts. The high-efficiency and low-trash content cotton picker adopts a hand-held structure, is reasonably designed, and is convenient to hold; in addition, a trigger type switch is used for controlling the switching and rotational speed of the motor, so operation is flexible; the high-efficiency and low-trash content cotton picker can perform specific picking, decreases the trash content of cotton, increases the efficiency of cotton picking, and has remarkable practicability.

Description

technical field [0001] The invention relates to an agricultural implement, in particular to a mechanical device for picking cotton. Background technique [0002] Cotton is a relatively common agricultural crop, and it is more commonly planted in my country. During the cotton planting process, cotton picking and harvesting is the most important and difficult link. In traditional agriculture, most of the cotton harvesting relies on the cotton farmers to pick by hand. The operation is cumbersome, the efficiency is extremely low, and the cotton farmers’ work intensity is high. [0003] The use of mechanization instead of manual cotton picking can theoretically make up for the shortcomings caused by manual cotton picking in the past, but the current automatic cotton picking technology is not yet mature, and there are still many technical problems that need to be solved urgently.

Problems solved by technology

In traditional agriculture, most of the cotton harvesting relies on the cotton farmers to pick by hand. The operation is cumbersome, the efficiency is extremely low, and the cotton farmers’ work intensity is high. Not only does the cotton farmer suffer from backaches, but the tip of the cotton bolls is easy to cause damage to the hands.

[0003] Using mechanization instead of manual cotton picking can theoretically make up for the shortcomings caused by manual cotton picking in the past, but the current automatic cotton picking technology is not yet mature, and there are still many technical problems that need to be solved urgently

The current cotton picking machines are mainly divided into relatively large walking cotton picking machines and relatively small hand-held cotton picking machines. The degree of maturity and maturity time are different, so it must be picked in stages according to the maturity, while the walking cotton picker will crush the cotton plants when walking, and cannot be picked in stages

The hand-held cotton picker is relatively small and hand-held. It has the advantages of convenient use, compact structure, higher efficiency than pure manual picking, flexible operation, and targeted picking. However, the current hand-held cotton pickers mostly use the roller type. Picking mechanism, and only a small part of cotton is exposed to the outside of the cotton bolls, the cotton cannot be accurately and effectively contained during picking, and its picking efficiency still needs to be improved. At the same time, it also has disadvantages such as high power consumption and high impurity content

In addition, there are also cotton picking devices based on negative pressure adsorption. Its principle is similar to that of a vacuum cleaner. It has a medium volume and needs to be moved on its back, which increases the load on the cotton farmers. At the same time, it fails to solve technical defects such as high energy consumption and high impurity content.
