Embodiment

[0021] Randomly select 135 rice ears, cut the ears and dry them in the sun, then put the rice ears into the threshing system for threshing, collect the grains from the grain collection device, the shriveled grain collection device and the branch recovery device respectively, calculate and analyze all The total number of grains (TN), the number of unshed grains (LN), the number of broken grains (BN), the attached instructions Figure 5 It is the result of the test of the present invention. The average threshing error (ATLP) and average threshing damage rate (ABTP) of the system were statistically analyzed, and the average threshing error of the threshing system was about 0.87%, and the threshing damage rate was about 0.05%. It can be seen that the threshing system meets the threshing requirements of automation, high precision and high efficiency.

Abstract

The invention discloses a single-plant high-precision full-automatic threshing system based on combination of a scraping type and a rolling type, which comprises a scraping type threshing assembly, arolling type threshing assembly, a shrunken grain and branch-trunk separating assembly, and a PLC controller. The scraping type threshing assembly is obtained through transformation according to artificial threshing, and most of the solid grains can be threshed with almost zero shell breaking rate; the rolling type threshing assembly is used for threshing the shrunken grains which are difficult to thresh, so that the precision of the threshing system is ensured. The threshing system has the advantages of high precision, high efficiency and high automation degree, and the threshing system is suitable for automatic treatment of rice ears in the early stage of single-plant high-precision seed selection, thereby providing powerful support for fine agricultural research.

Description

technical field [0001] The invention relates to the field of agricultural machines, in particular to a fully automatic grain separation device combining scraping and rolling. Background technique [0002] Rice threshing is an indispensable part of rice breeding research, and it is also a very important research content in the field of agricultural machinery automation. The purpose of threshing is to completely remove all the grains on the rice ear branches, so as to investigate the properties of the grains. In agricultural scientific research, it is required to separate all the grains, including full grains and shriveled grains, from the branches and require zero residue, which is used to examine grain shape, seed setting rate, fullness, thousand-grain weight, etc.; this is different from agricultural production Although threshing is also needed in agricultural production, it only cares about the final yield part, so it only requires that the full grain part be taken off. ...
