Description

One sampler that grows cotton
Technical field
The present invention relates to the sampler that grows cotton, particularly relate to a kind of cotton sampler with circular cutting type sampling cutter and cotton sample pawl.
Background technology
Bale of cotton sampling is mainly hand sampling and mechanical sampling in the world at present, and mechanical sampling be hydraulic pressure cotton sample skewering machine taking U.S.'s development as main method, but the method belongs to semi-automatic sampling.
What the sampled part in the hydraulic pressure cotton sample skewering machine of U.S.'s development was taked is to erect parallel double knife structure, double-pole spacing is 150 mm, when sampling, cut the bale of cotton from indentured both sides by hydraulic valve control double-pole, move from top to bottom and two of the bale of cotton two lateral incisions are about to the large openning of 254 mm, by manually making transverse cuts with cutter, then take out by hand cotton sample, wide 150 mm of sample of taking-up again, be about 230 mm, heavily approximately 170 g left and right.(details with reference to United States Patent No. 3464298, Cotton Bale Sampling Machine, 1969)
