Air-suction-type seed sowing device for seeding machine

Abstract

The invention discloses an air-suction-type seed sowing device for a seeding machine. The air-suction-type seed sowing device comprises a seed pickup device. The seed pickup device comprises a shell, a cover plate and a seed storage plate. A motor is arranged on one side of the cover plate. The output shaft of the motor stretches into the shell. A seed sowing disc is installed on the part of the output shaft in the shell. A plurality of seed suction ports I are arranged in the seed sowing disc. A seed outlet is arranged in the bottom of the shell. A seed inlet pipe is arranged on one side of the cover plate far away from the shell. A seed inlet is arranged in the cover plate. A sealing cover device is installed on one side of the shell far away from the seed inlet pipe. The sealing cover device comprises a boarding I. A baffle I is arranged on the boarding I. An air outlet I is arranged on the baffle I. An air damper corresponding to the position of the seed suction ports I which are arranged at the lowest position of the seed sowing disc is arranged in the boarding I. The air-suction-type seed sowing device additionally comprises a monitoring and control system which is used for monitoring whether the seed suction ports I suck seeds in real time and controlling the motor. Since the air-suction-type seed sowing device is driven by the motor, the defect that a floor wheel slips in the prior art is avoided, the situation of miss seeding can be automatically detected and the seeds can be replenished in time.

Description

technical field [0001] The invention relates to a seed metering device for a seeder, in particular to an air suction seed metering device for a seeder. Background technique [0002] To plant various crops on limited land and ensure the maximum effective use of cultivated land area, the success of sowing is the key factor. In the past, manpower was used to sow seeds. Although this method could ensure the seeding rate, the efficiency was too low. Now mechanized farming methods are adopted, and the speed of sowing has increased, but there are many unstable factors, such as mechanical failure of the seeder, The emptying of the seed box, the blockage of the seed guide pipe, and the blockage of the opener by soil clods will cause one or several rows of seed pipes to fail to sow normally, resulting in missed sowing. Especially large-scale wide-width precision seeding machines have high operating speed and wide broadcasting width. Once the above phenomenon occurs, it will cause a l...

In the past, manpower was used to sow seeds. Although this method could ensure the seeding rate, the efficiency was too low. Now mechanized farming methods are adopted, and the speed of sowing has increased, but there are many unstable factors, such as mechanical failure of the seeder, The emptying of the seed box, the blockage of the seed guide pipe, and the blockage of the opener by soil clods will cause one or several rows of seed pipes to fail to sow normally, resulting in missed sowing

Especially the large-scale wide-width precision seeding machine has high operating speed and wide broadcasting width. Once the above phenomenon occurs, it will cause a large area of ​​missed seeding, which will inevitably cause serious losses in agricultural production.
