Cotton sampling device

Abstract

The invention relates to a cotton sampling device, particularly to a cotton sampling device provided with a round cutting type sampling cutter and a cotton sample claw. The sampling device is composed of a mechanical executive device and a programmable logic controller (PLC) electric control system, wherein the mechanical executive device is composed of a cotton sampling unit, a cotton bale conveying clamping unit, a cotton bale on-site steering conveyor, a dynamic weighing unit and a conveying raceway; the cotton bale on-site steering conveyor is connected with the dynamic weighing unit and the conveying raceway in front and the cotton conveying clamping unit and the cotton sampling unit on the side sequentially. Round cutting type sampling can be achieved through the cotton sampling cutter, the cotton sample claw can grab cotton samples out after the cotton sample cutting and then release the cotton samples, namely, feeding forward and round cutting are performed simultaneously, the obtained cotton samples are in cake shapes, and the sampling depth can be adjusted freely 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 a cotton sample claw. Background technique [0002] At present, cotton bale sampling in the world is mainly manual sampling and mechanical sampling, and mechanical sampling is the main method of hydraulic cotton skewer developed by the United States, but this method is semi-automatic sampling. [0003] The sampling components in the hydraulic cotton skewer machine developed by the United States are located on both sides of the bale raceway. It adopts a vertical parallel double-knife structure with a distance of 150 mm. The double-knife is controlled by a hydraulic valve to cut in from both sides of the bale body during sampling. In the cotton bale, cut two large openings about 254 mm in length on both sides of the cotton bale by moving from top to bottom, and then manually cut the cotton sample horizontally with a knife....

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

In addition, the sampling equipment in the prior art does not have a device with a cotton bale steering function and a cotton bale weighing function, so that the cotton bale weight inspection and cotton sampling work cannot be completed at the same time
