Cotton separating device

Abstract

The invention relates to a cotton separating device, which comprises a shell and a bracket, wherein the bracket is provided with a motor used for driving a working mechanism in the shell; the shell is provided with a feed inlet and a cotton outlet and is a cylindrical barrel; the bracket is arranged below the shell and supports the barrel; the upper surface of the shell is provided with a circular charging opening, the upper part of the side wall of the shell is provided with a fragment outlet, and the lower part of the upper side wall of the shell is provided with the cotton outlet at a position corresponding to the fragment outlet; and the bracket is fixedly provided with the motor which is connected with the lower surface of the shell via a flange and a fixed lead screw, the output shaft of the motor penetrates through the central part of the lower surface of the shell upwards to be fixedly connected with the center shaft of vanes, and the multiple vanes are arranged in an axisymmetric manner. The cotton separating machine in the invention has small volume and convenient use, and is quite suitable for small-scaled cotton growers to use.

Description

technical field [0001] The invention relates to an agricultural product processing machine, in particular to a small machine for cotton shelling. Background technique [0002] Cotton hulling is an important step in cotton production and processing. The traditional manual method is inefficient and only suitable for small-scale planting. After the scale is enlarged, pure manual labor cannot be completed. There are also special machinery now, and the special machinery mostly adopts the form of pressing roller to crush the cotton shells, and then separates them. For example, a utility model patent for a cotton shelling and leaf separating machine (patent number: 200720311258.9, patentee: Wang Wenwen, application date: December 14, 2007). Its technical scheme is as follows: a cotton shelling and leaf separating machine, which is provided with a frame, a motor and a cotton feeding hopper, and the frame is respectively fixed with an auger conveying device, a cotton husk separatin...

AI Technical Summary

Problems solved by technology

In the scheme of the above-mentioned patent, the separation of cotton husks is in the form of crushing and separation, which will cause the cotton husk debris to adhere to the cotton fibers, making it difficult to share and affecting the quality of cotton

Another very important aspect, the shelling machine in the form of roller crushing is large in size and complex in structure, and correspondingly, the cost is relatively high, so it is not suitable for small-scale household contracted land planting in rural China.
