Automatic seed selecting method and seed taker

Abstract

The invention discloses an automatic seed selecting method, which includes the following steps: (1), arranging an automatic seed taker, (2), starting a seed feeding device for feeding seeds to be sorted in a seed trough into a seed taking cavity of a seed transmission mechanism one by one; (3) adopting a control device to output compressed air with set parameters to the seed transmission mechanismthrough a compressed air output port, so as to complete automatic sorting and seed taking of one single seed, wherein the compressed air horizontally blows to the seeds to be sorted. The invention further discloses a seed taker adopting the method. According to the invention, the wind power sorting, transmission and collection method with gravity+compressed air+suspension flying is adopted for seeds, seeds can be accurately judged and sorted based on three seed indexes of grain size, shape and weight, so that seeds with a mixture of varieties, and seeds which are partially qualified and partially disqualified can be conveniently, quickly and accurately sorted, conveyed and collected without damage.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry machinery, in particular to an automatic seed picking method and a seed picking device. Background technique [0002] Plant active seeds (solid grains) are valuable biological genetic resources and the material basis for the protection of plant resources. In the process of sorting, distributing and taking seeds, sorting and packing of seeds is an important step, not only need to control the quantity or quality of seeds taken, but also need to operate carefully to avoid the selection of unqualified seeds and Avoid confusion with seeds of other varieties. In the process of the above operation, it often takes too long time due to the huge quantity of distributed seeds and cumbersome operation steps. At the same time, due to the lack of relevant quantitative seed packaging devices during manual sorting, the metering of the packaging is not accurate. [0003] The existing sorting an...
