Problems solved by technology

Therefore, when the existing air-suction plate seeder is working, a reciprocating swing mechanism or a two-degree-of-freedom manipulator is generally used to drive the seed-suction plate to suck and discharge seeds. , it is easy to cause the adsorbed seeds to fall off halfway, resulting in holes and affecting the quality of sowing

Abstract

The invention discloses an air suction plate type seeder. The air suction plate type seeder mainly comprises a rack, a seed suction plate, a seed box, a guide rod, a pneumatic vibrator, a rotating shaft, an air cylinder I, and an air cylinder II. The pneumatic vibrator is arranged on the seed box; the seed box is driven by the air cylinder I to move up and down along the guide rod; and the seed suction plate is driven by the air cylinder II to turn over. The seeder can be used for air suction type precise seeding of small-particle seeds, the seed suction plate moves steadily, and the seed falling caused by shock vibration can be avoided, so that the miss-seeding rate can be reduced and the seedling cultivation cost is lowered.

Description

technical field [0001] The invention belongs to the field of precision sowing of agricultural machinery, and in particular relates to an air-suction plate seeder suitable for precision sowing of plug trays. Background technique [0002] The air-suction seeder uses the adsorption force of the airflow to absorb the seeds from the seed pile, so as to realize the precise sowing of single or multiple seeds. It has strong adaptability to the seed type, does not damage the seeds, and can work at high speed. It is currently the most used way of sowing. According to the structure of the sowing parts, the existing air-suction seed metering devices can be mainly divided into needle-suction type, drum-type and suction-plate type. [0003] The working principle of the air suction plate seeder is: turn on the air pump switch, pump out the gas in the air cavity on the back of the seed suction plate, and form a negative pressure in the air cavity, when the seeds slide through the seed suct...
