Abstract

The invention discloses a high-speed multifunctional precise-amount seed-metering device, which solves the problem that the seed fetching performance is poor, seeds cannot be accurately sowed and sowing seed type is limited when the traditional seed-metering device sows at a high speed. A driving gear, a slanting slideway disc and an annular seed discharging impeller are sequentially fixed from the back to the front on a rotary shaft; a flow dividing disc is arranged behind the slanting slideway disc; a vacuum chamber seat is fixed behind the flow dividing disc; a plurality of radial slotted holes are uniformly distributed on the edge of the slanting slideway disc; the flow dividing disc is provided with a parabolic slotted hole communicated with the radial slotted holes; a speed accelerating wheel eccentric with the seed discharging impeller is arranged in the centre of the seed discharging impeller; a seed discharging port and a rotation speed sensor which swing left and right are respectively arranged on the lower part of a seed discharging shell and on the inner wall of the seed discharging shell corresponding to the seed discharging impeller; a photoelectric sensor used for detecting seed loss is arranged on the inner wall of a front end cover; and a hall sensor used for detecting the seed quality is arranged on the seed discharging port. The high-speed multifunctional precise-amount seed-metering device has a reasonable and reliable structural design, guarantees the seed absorption performance of the slanting slideway disc and meets the requirements on precise amount and precise sowing.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a high-speed multifunctional precision metering device. Background technique [0002] The development of world agricultural science has moved from the pursuit of extensive production increase mode to modern precision agriculture with harmonious development of economy and environment. The development of modern seeding technology and equipment, and the efficient use of land resources, water resources, seeds, pesticides, fertilizers and other production factors are of great significance for improving the comprehensive production capacity of agriculture, ensuring food security and promoting the sustainable development of the world. [0003] Precision seeding technology is the organic combination of modern science and technology of agronomy and agricultural machinery, which is the technology of sowing single seeds equidistantly into the soil to a predetermined depth. Precision s...
