High-speed multifunctional precise-amount seed-metering device

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.
