Detailed Description
The structural principles and embodiments of the present invention are described in detail below with reference to fig. 1.
The invention relates to an anti-electromagnetic mutual interference type high-voltage electrostatic clockwork roller, which mainly comprises a 1-combined type dielectric insulating layer, a 3-metal type hole shielding layer, a 4-seed box, a 6-copper sheet, an 11-conveying device and a high-voltage electrostatic generator. The seed metering roller is characterized in that a seed metering roller base body is composed of a 1-combined type dielectric insulating layer, a 3-metal type hole shielding layer and a 6-copper sheet, the 1-combined type dielectric insulating layer is composed of eight dielectric insulating layer monomers, and the 6-copper sheet is arranged between every two dielectric insulating layer monomers. The 6-copper sheet can isolate electromagnetic fields in two adjacent dielectric insulation layer monomers, prevent the mutual interference of the electromagnetic fields between the adjacent dielectric insulation layer monomers and meet the requirement of precision seeding.
The working process of the invention is as follows: when the device works, the positive and negative polarity high-voltage electrostatic generators are switched on, under the excitation action of an electric field generated by the positive polarity high-voltage electrostatic generator, the 1-combined dielectric insulating layer and the 2-seed surface generate polarized charges with equal size and opposite polarity, and under the action of mutual attraction of opposite charges and the 3-metal type hole shielding layer, only 8-type holes generate adsorption force, so that seeds are adsorbed and taken; the adsorbed seeds move along with the roller; under the excitation action of an electric field generated by a negative polarity high-voltage electrostatic generator, the surface of the 1-combined type dielectric insulating layer generates charges with the same polarity as that of the 2-seeds, the seeds fall into a 10-hole tray through a 9-seed falling channel under the action of the repulsion of like charges, and the 10-hole tray moves along with an 11-conveying device, so that the precision seeding requirement is met.
