The invention discloses an impurity screening and separation mechanism of a wheat single-grain seeder, which belongs to the field of wheat seeding impurity screening. An impurity screening and separation mechanism for a wheat single-grain planter, comprising a screening box, the inner wall of the screening box is fixedly connected with an arc-shaped filter screen; the inside of the screening box is rotatably connected with a reciprocating screw rod, A slider is threaded on the reciprocating screw rod, and the bottom of the slider is slidably connected with a screening plate matched with the filter screen. The bottom of the screening plate is provided with sawtooth grooves; the screening box is provided with a frame plate, the frame plate is located below the filter screen, the frame plate is provided with a raised portion, and the frame plate and the raised portion are provided with filter holes; the frame plate is slidably connected with a push block, the The bottom of the pushing block is provided with a planting rod; the invention can effectively screen and separate impurities in wheat seeds during sowing, reduces labor intensity, improves work efficiency, and is easy to use.
Description
An impurity screening and separation mechanism of a wheat single-grain planter technical field The present invention relates to wheat sowing impurity screening technical field, relate in particular to a kind of impurity screen of wheat single-grain seeder Separation mechanism. Background technique In order to carry out novel breeding to wheat, purposefully and plannedly obtain the new wheat variety that people need, scientific research Personnel need to continuously carry out breeding research on wheat. At present, major breakthroughs have been made in the breeding research of hybrid wheat in my country. The independent two-line method and hybrid wheat application technology have a significant effect on improving food production cost savings and efficiency, and are widely used in wheat breeding. In the process of single-seed planting, a single-seed seeder needs to be used to assist wheat single-seed planting. In wheat single-seed sowing, the Screening and separatin...
