Automatic equipment for crop seed testing

Abstract

The invention discloses automatic equipment for crop seed testing. The automatic equipment comprises a miniature threshing device, a purity winnowing device and an automatic grain counting device in sequential connection. The miniature threshing device, the purity winnowing device and the automatic grain counting device synergistically complete part of seed testing operations through cross coordination. The automatic equipment has advantages that automation and standardization in part of the seed testing process are realized, and seed testing efficiency and accuracy are remarkably improved.

Description

technical field [0001] The invention relates to the technical field of crop seed selection, in particular to an automatic equipment for crop seed roasting. Background technique [0002] The roasted seeds of the ear of the crop include the specific indicators of the yield components such as the number of grains per ear, seed setting rate, and thousand-grain weight. The past seed roasting process was particularly cumbersome, and there were relatively large human factors. For example, different people’s different standards for distinguishing full grains would lead to large differences in statistical results of seed setting rate, and even the same person’s distinction of full grains at different times There is also inconsistency in standards. In short, the deviation of human judgment leads to large errors in the results of seed roasting, which in turn makes the statistical results lack of credibility. During the manual threshing process, it is inevitable that there will be spl...

Problems solved by technology

In the process of manual threshing, it is inevitable that there will be splashing of seeds, and it is difficult to guarantee the accuracy of manual counting, etc. These are the problems in the roasting process.

[0003] Although there are different types of threshers on the market (larger, suitable for threshing a large number of ears during yield measurement, but not suitable for the shedding of single ears or single-stem grains in the later roasting process), the seed clarity winnowing instrument ( The type is large and cannot be connected with other instruments), and automatic particle counting instrument

However, they are all independent devices and cannot be used in combination, so the improvement of the whole process of roasting seeds is not obvious
