Description
Technical field
The present invention relates to the sampling head that grows cotton, particularly relate to a kind of cotton sampling head 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 take 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 the parallel double knife structure, the double-pole spacing is 150mm, cut the bale of cotton from indentured both sides by hydraulic valve control double-pole during sampling, move from top to bottom two large opennings that are about 254mm of the bale of cotton two lateral incisions, by manually making transverse cuts with cutter, then take out by hand cotton sample, the wide 150mm of the sample of taking-up again, be about 230mm, heavily approximately about 170g.(details are with reference to United States Patent No.3464298, Cotton BaleSampling Machine, 1969)
The sampling equipment of China state cotton has also been developed the cotton sampled part that similar band is erect parallel double knife type sampling cutter on the experiential basis of the U.S., need equally manually to make transverse cuts with cutter, then the manual cotton sample of taking out.
As: utility model patent publication number CN2693657, with the hydraulic cotton press of automatic sampling device.
Above two kinds deficiency and defective: the cotton sample that all can only obtain bale of cotton top layer; Need to then take out cotton sample by hand by manually making transverse cuts with cutter, can not arrive full-automatic sampling; The degree of depth of sampling is limited by the width of blade, can not regulate.
The band of prior art is erect the cotton sampling head of parallel double knife structure cutter, all is the blade that has adopted sheet type, these blades can only the unidirectional vertical insertion bale of cotton in, the cutting action such as can not turn round.And the blade of prior art is in inserting bale of cotton process, because the blade angle of blade is very little, and two-sidedly all fits with cotton, and resistance is very large, can not realize degree of depth sampling.
The circular cutting type sampling of the bale of cotton there is no relevant document record at present, be applicable to the circular cutting type sampling cutter of band of circular cutting type sampling and the cotton sampling head tool of cotton sample pawl and have no way of especially reporting, the sampled part in the sampling equipment of prior art can't be applied to this kind occasion at all.
