Description
Technical field
The present invention relates to one to grow cotton sampling head, 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 is with the hydraulic pressure cotton sample skewering machine of U.S.'s development for 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 erect parallel double knife structure, double-pole spacing is 150mm, double-pole is controlled from the indentured both sides incision bale of cotton by hydraulic valve during sampling, move from top to bottom and the bale of cotton two lateral incision two is about the large openning of 254mm, make transverse cuts by artificial cutter again, then take out cotton sample, the wide 150mm of sample of taking-up by hand, be about 230mm, heavily about about 170g.(details reference United States Patent No.3464298, Cotton BaleSampling Machine, 1969)
The sampling equipment of state of China cotton also have developed the cotton sampled part that parallel double blade sampling cutter erect by similar band on the experiential basis of the U.S., and transverse cuts made by the artificial cutter of same needs, then takes out cotton sample by hand.
As: utility model patent publication number CN2693657, with the hydraulic cotton press of automatic sampling device.
The deficiency of above two kinds and defect: the cotton sample that all can only obtain bale of cotton top layer; Need to make transverse cuts by artificial cutter, then take out cotton sample by hand, full-automatic sampling can not be arrived; The degree of depth of sampling is limited by the width of blade, can not regulate.
The cotton sampling head of parallel double knife structure cutter erect by the band of prior art, is all the blade that have employed sheet type, and these blades in the unidirectional vertical insertion bale of cotton, can only can not carry out the cutting actions such as revolution.And the blade of prior art is in insertion bale of cotton process, because the blade angle of blade is very little, and two-sidedly all fit with cotton, resistance is very large, can not realize the degree of depth and sample.
The circular cutting type sampling of the bale of cotton there is no relevant document at present and records, the cotton sampling head tool of the circular cutting type sampling cutter of band and cotton sample pawl that are applicable to the sampling of circular cutting type has no way of reporting especially, and the sampled part in the sampling equipment of prior art cannot be applied to this kind of occasion at all.
