Device and method for testing cotton-containing power of cotton boll shell

Abstract

The invention discloses a device for testing the cotton content of a cotton boll shell. The device comprises a seed cotton extracting device, a three-dimensional force measuring device, a cotton boll shell angle adjusting device and a control device, wherein the seed cotton extracting device comprises a seed cotton chuck and a seed cotton extracting driving device; the three-dimensional force measuring device comprises a cotton boll clamp and a three-dimensional force sensor; the cotton boll shell angle adjusting device comprises an angle adjusting plate and an angle adjusting frame; and the control device is in communication connection with the seed cotton extracting device and the three-dimensional force measuring device so as to regulate and control the seed cotton extracting angle and speed of the seed cotton chuck. The device provided by the invention can measure the size of the cotton boll shell flocculability of different varieties from two parameters of seed cotton extraction angle and speed, provides reference for cotton genetic breeding in the aspect of flocculability, and enables agronomic characters to be matched with cotton picking machinery to the greatest extent, thereby greatly improving the complete picking rate of mechanical picking. The invention further provides a cotton boll shell flocculability testing method based on the cotton boll shell flocculability testing device.

Description

technical field [0001] The invention belongs to the field of cotton variety breeding research, and relates to an experimental testing device, in particular to a measuring device and a testing method for measuring the flocculation force between seed cotton and boll shells during the cotton picking process. Background technique [0002] Cotton wadding with strong cotton wadding ability is in a state of embracing, does not sag, and does not split if it is not picked for a long time. It is called wadding, and it is likely to develop into residual cotton; The formation of split flocs hanging or even falling off automatically before harvesting is called split flocs, which is most likely to develop into nodding. [0003] At present, cotton is mostly picked by machines. When cotton is harvested mechanically, too strong cotton opening and flocculation content will cause the seed cotton to be harvested uncleanly during machine picking, resulting in a reduction in production. Low cott...

Problems solved by technology

[0005] However, at present, there is no special device for testing the floc content of seed cotton in my country. Usually, only experience is used to judge the floc content of seed cotton, but it is impossible to obtain an accurate value of floc content, and the test results are not objective enough.
