Problems solved by technology

However, compared with the mechanical structure, the amplitude of the electromagnetic vibration structure is significantly reduced, making it difficult for the seeds in the seed tray to achieve the "boiling" effect, making it difficult for the suction cup type seed meter to achieve a satisfactory seed suction effect; at the same time, the existing precision seeding device The working parameters are single and fixed, and there is still a lack of automatic adjustment and adaptive control under different working conditions

Abstract

The invention provides a blowing-suction electromagnetic vibration precision seeding device and its control method. The suction plate is composed of multiple small air chambers, the suction hole of the bottom suction cup is equipped with a tapered suction nozzle part, the multi-air chamber partial pressure suction plate is connected with the two-degree-of-freedom manipulator; the blowing vibration seed plate device includes a top-to-bottom The vibrating seed plate, the hollow tray and the open three-layer blowing chamber are fixed in sequence, and the tray is fixed with the electromagnetic vibrator; the electromagnetic vibrator includes an adjustment shaft, a coil and an armature, and the armature and the adjustment shaft are coaxially arranged on the coil Inside, the coil is placed inside the coil fixing seat, the adjustment shaft is located above the armature, and there is a gap between the two. The invention can improve the segregation phenomenon of the populations in the seed tray, better increase the dispersion among the populations, and at the same time uniform and stabilize the seed suction airflow and improve the seed suction rate.

Description

technical field [0001] The invention belongs to the technical field of agricultural mechanized seeding, and in particular relates to a blowing-suction electromagnetic vibration precision seeding device and a control method thereof. Background technique [0002] Seedling raising and sowing is one of the most critical links in industrialized seedling raising. The qualified rate of sowing effect, missed sowing rate and reseeding rate will directly affect the cost of seedling raising and the rate of seedling and strong seedling raising, and also have an impact on the final rice yield. Significantly affected. The vibrating air-suction precision seeding device uses the working principle of combining vibration and air suction. It has the advantages of simple structure, strong adaptability to the shape of seeds, can sow germination seeds and does not damage the seeds, and can meet the requirements of super hybrid rice 2±1 The requirement of grain / hole precision seedling raising and...
