Double-shielding type precision seedling raising and sowing device and double-shielding type precision seedling raising and sowing method

Abstract

The invention relates to a double-shielding type precision seedling raising and sowing device and method. The double-shielding type precision seedling raising and sowing device is structurally and mainly composed of an electrostatic generator positive pressure output electrode, an electrostatic generator negative pressure output electrode, a dielectric insulating layer, a metal hole shielding layer, a metal shielding plate, a hole and a hole tray. The roller is characterized in that the metal type hole shielding layer is attached to the surface of the dielectric insulating layer to form a roller base body, and type holes adaptive to morphological characteristics and sizes of seeds are evenly distributed in the surface of the roller base body. Under the excitation of an electric field generated by the positive voltage output electrode, charges with the same size and opposite polarities are generated by the dielectric insulating layer and the seed surface, and adsorption force is only generated in the type hole under the action of attraction of charges with different polarities and the metal type hole shielding layer, so that quantitative adsorption and seed taking are realized; under the excitation of an electric field generated by the negative pressure output electrode, charges with the same polarity are generated by the dielectric insulating layer and the surfaces of the seeds, and the seeds fall into a hole tray through the seed guide channel under the repulsion action of the charges with the same polarity, so that the requirement of precision seeding is met.

Description

technical field [0001] The invention relates to a double-shielding precision seedling raising and sowing device and method, belonging to the field of precision sowing equipment. Background technique [0002] The plug seedling seeding machine is the core component of the seedling seeding equipment. At present, the most common application at home and abroad is the air-suction plug seedling seeding machine. In order to improve the seeding accuracy and reduce energy consumption, the existing air-suction seeding machines generally use small apertures. , Long-lead suction hole, facing the small-sized and irregular vegetable seeds (such as thread peppers, processed tomatoes, etc.) The technical bottleneck problem restricts the application and promotion of the existing air suction hole tray seedling seeding machine in the large-scale planting of irregular small particle vegetable seeds.
