Description

Technical Field

[0001] The utility model belongs to the technical field of seeding device equipment, in particular to an air suction seeding device. Background Art

[0002] The air suction seed metering device consists of three main parts: a negative pressure chamber, a seed chamber and a suction cup. The suction cup separates the negative pressure chamber and the seed chamber. When working, the negative pressure chamber generates air negative pressure under the action of the fan, so that the seed suction holes on the suction cup generate airflow from the seed chamber to the negative pressure chamber. The airflow drives the seeds in the seed chamber to cling to the seed suction holes of the suction cup. As the suction cup rotates, the seeds attached to the seed suction holes are taken out of the seed metering device. After reaching the boundary of the negative pressure chamber, the negative pressure is eliminated and the seeds are discharged under the action of gravity, achieving the purpose of sowing.

[0003] However, when the existing air suction seeding device is in use, since the suction disk is round, when it falls by gravity, adjacent seeds are likely to fall at the same time, resulting in uneven seed spacing and affecting plant growth. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model proposes an air suction seeding device, which effectively solves the problem that when the air suction seeding device on the market is in use, adjacent seeds fall at the same time when falling by gravity, the seed spacing is uneven, and the growth of the plants is affected.

[0005] The technical solution adopted by the utility model is as follows: the utility model proposes an air suction seed-drying device, including a fixed column, a negative pressure adsorption seed-drying structure and a driving structure, the negative pressure adsorption seed-drying structure is arranged on the fixed column, the driving structure is arranged on the negative pressure adsorption seed-drying structure, the negative pressure adsorption seed-drying structure includes a hollow seat, an air suction nozzle, a seed groove, an air hole, a track, a rotating negative pressure seat, an air duct, an adsorption groove and a partition, the hollow seat is fixedly arranged on the fixed column, the air suction nozzle is penetrated through the hollow seat, the seed groove is penetrated through the fixed column and wrapped on the hollow seat, the air hole is penetrated through the hollow seat, the track is wrapped around the hollow seat, the rotating negative pressure seat is rotatably arranged on the track, the air duct is penetrated through the rotating negative pressure seat, the adsorption groove is penetrated through the rotating negative pressure seat, and the partition is fixedly arranged on the hollow seat.

[0006] Preferably, the driving structure includes gear one, a fixed seat, a motor and gear two, wherein gear one is wrapped on a hollow seat, the fixed seat is fixed on the seed slot, the motor is fixed on the fixed seat, and gear two is driven on the motor and meshed with gear one.

[0007] In order to better achieve the effect of adjusting the sowing spacing, the rotation speed of the gear 2 can be adjusted according to the sowing spacing.

[0008] In order to achieve the purpose of sowing faster, the partitions are symmetrically arranged in two groups on the suction nozzle, and the partitions are sealed and slidably arranged with the internal channel of the rotating negative pressure seat.

[0009] Furthermore, the track and the rotating negative pressure seat are sealed with each other.

[0010] In order to achieve the adsorption effect, the air channel keeps the air hole connected with the rotating negative pressure seat to form negative pressure.

[0011] The beneficial effects achieved by the utility model using the above structure are as follows: This scheme proposes an air suction seed metering device, in which a vacuum pump is connected to the suction nozzle to evacuate the rotating negative pressure seat and the hollow seat, thereby forming a negative pressure. At this time, the adsorption groove adsorbs the seeds in the seed groove. When the seeds in the adsorption groove rotate between the two sets of partitions, the negative pressure in the partition disappears. At this time, the seeds fall from the partition, preventing seeds in other positions from falling prematurely and affecting the spacing. BRIEF DESCRIPTION OF THE DRAWINGS
