Intelligent agricultural seeding machine

Abstract

The invention discloses an intelligent agricultural seeding machine which comprises a conveying device and a PLC, the top of the conveying device is fixedly connected with two racks, a plurality of seeding parts distributed in the axial direction are arranged on a guide shaft, and an adjusting part for adjusting the distance between every two adjacent seeding parts is arranged between the two racks. According to the device, the driving piece drives the rotating disc assembly to rotate, the suction head sucks seeds and moves the seeds to pass through the first check block and the second check block, the seeds move back and forth on the suction head under the blocking effect of the two check blocks, therefore, redundant seeds are separated from the suction head due to extrusion, the two check blocks extrude the seeds from the upper direction and the lower direction respectively, and the seeds are separated from the suction head. And the suction head covers half of the area of the air inlet end of the suction head, so that the device can effectively remove the seeds which are adsorbed on the suction head and have smaller particle sizes, the effects of saving the seeds and reducing the cost are achieved, and the normal development and growth of the seeds are facilitated.

Description

technical field [0001] The invention relates to the technical field of agricultural planting, in particular to an intelligent agricultural planting machine. Background technique [0002] Sowing is a basic link in agriculture, and the quality of sowing will affect the rate of emergence in the future. The seeds of most plants can be directly sown in the field. For the seeds with weaker seedlings, it is necessary to raise seedlings in the seedbed first, and the method of seedling raising in plug trays is often used. The technology of plug seedling cultivation is to use peat, vermiculite and other light matrix soilless materials as the seedling substrate, use the plug tray as the seedling container, mechanized precision seeding, and the modern seedling raising technology of one hole and one grain when the plug seedling is planted, and one-time seedling formation. , when the seedlings are grown, there is one plant in one room, and the seedlings are of high quality, easy to stand...

Problems solved by technology

[0004] However, in the prior art, for small-sized seeds, due to the small volume and quality of the seeds, it is likely that one seed suction hole will absorb multiple seeds under the action of negative pressure, resulting in sowing multiple seeds on one plug. , waste seeds, increase the cost, and even affect the normal seedling raising in the later stage; in addition, when the seeds are sucked under negative pressure, they cannot be absorbed accurately, resulting in air suction in one or some of the seed suction holes, so that it is impossible to sow seeds in the plug trays, and it is impossible to achieve precision seeding
