Cotton sampling device

Abstract

The invention relates to a cotton sampling device, which mainly includes a base, a moving rack, a sampling head support, a cotton sampling head, a propulsion device and a sampling head feeding moving device, wherein the cotton sampling head is mounted on the sampling head support; the sampling head support is linked with the base through the moving rack; the moving rack is driven by the propulsion device; and the sampling head feeding moving device realizes the feeding and cutter retraction of the cotton sampling head. The invention relates to a cotton sampling device, and mainly relates to a cotton sampling device with an annular cutting sampling cutter and a cotton sample claw; the cotton sampling cutter can be used for sampling in an annular cutting manner; the cotton sample claw can be used for catching the cotton sample after the cotton sample is cut and then releasing the cotton sample, namely moves forwards while annularly cutting; the obtained cotton sample takes a shape of a round pie; and the sampling depth can be adjusted at will as required.

Description

technical field [0001] The invention relates to a cotton sampling device, in particular to a cotton sampling device with a circular cutting type sampling knife and cotton sample claws. Background technique [0002] At present, cotton bale sampling in the world is mainly manual sampling and mechanical sampling, and mechanical sampling is mainly based on the hydraulic cotton cutting machine developed in the United States, but this method belongs to semi-automatic sampling. [0003] The sampling part in the hydraulic cotton cutting machine developed in the United States adopts a vertical parallel double-knife structure, and the distance between the two knives is 150mm. When sampling, the hydraulic valve controls the two knives to cut into the cotton bale from both sides of the bag body, and the movement from top to bottom will Two large openings about 254mm in length are cut on both sides of the cotton bale, and then cut horizontally with a knife manually, and then the cotton s...

AI Technical Summary

Problems solved by technology

[0006] The shortcomings and defects of the above two types: both can only obtain cotton samples on the surface of the cotton bale; it needs to be manually cut horizontally with a knife, and then the cotton samples are taken out manually, which cannot achieve automatic sampling; the depth of sampling is limited by the width of the blade, can not be adjusted

[0007] The existing cotton sampling heads with vertical parallel double-knife structure knives all use thin blades. These blades can only be inserted into the cotton bale vertically in one direction, and cannot perform cutting actions such as rotation.

In addition, when the blade of the prior art is inserted into the cotton bale, because the blade has a very small edge angle and both sides are attached to the cotton, the resistance is very large, and deep sampling cannot be realized.

[0008] The circular cutting type sampling of cotton bale still does not have relevant bibliographical record at present, is applicable to the cotton sampling head with circular cutting type sampling knife and cotton sample pawl that is suitable for circular cutting type sampling especially has no way of reporting, the sampling of prior art Sampling components in the device simply cannot be used in this situation
