Centrifugal cone-disk high-speed seeding unit

Abstract

The invention provides a centrifugal conical disc type high-speed seed discharging single body. A seed filling and discharging mechanism composed of a seed discharging disc, a centrifugal conical disc, driving double sprockets and a fixed seed filling pipe, and a seed guide mechanism composed of a driven sprocket, a driving shaft, a supporting shaft, an annular seed guide belt and a U-shaped end cover are assembled at the upper part and lower part of opposite side faces of a U-shaped notch type fixed plate respectively; the chain sleeves the driving double sprockets and the driven sprocket; a conical seed filling groove, an annular sliding groove and an annular sheet groove are formed in the inner side face of the centrifugal conical disc; a bearing, an annular seed protection sheet, a blockage clearing sheet, a slope-shaped arc seed leading groove, a seed unloading through hole and a seed stopping block are arranged on the inner side face of the seed discharging disc. The single body provided by the invention is novel and reasonable in structure, high in seed filing rate, low in missed sowing rate, reliable to use, few in faults and high in working efficiency and is especially suitable for high-speed sowing work.

Description

technical field [0001] The invention belongs to agricultural machinery and mainly relates to a seed meter. Background technique [0002] Existing mechanical crop seed metering devices, including hole-and-hole wheel seed metering devices, spoon wheel seed metering devices, and finger-clip seed metering devices, cannot be used in high-speed seeding operations. When the equipment is running at high speed, the hole wheel or spoon wheel in the seed meter rotates very fast, and the filling process of seeds into the hole or spoon is very difficult, the seed filling rate drops sharply, and the missed seeding rate increases , seriously affecting the quality of sowing operations. The filling capacity of the air-suction seed meter is higher than that of the mechanical seed meter, but the air-suction seed meter must be matched with the fan system. Not only is the structure complex and huge, the manufacturing cost is high, but also the power consumption is large, and the operating cost ...

AI Technical Summary

Problems solved by technology

[0002] The existing mechanical crop seed metering devices, including hole-and-hole wheel seed metering devices, spoon wheel seed metering devices, and finger-clip seed metering devices, cannot be used in high-speed seeding operations.

When the equipment is running at high speed, the hole wheel or spoon wheel in the seed meter rotates very fast, and the filling process of seeds into the hole or spoon is very difficult, the seed filling rate drops sharply, and the missed seeding rate increases , seriously affecting the quality of sowing operations

The filling capacity of the air-suction seed meter is higher than that of the mechanical seed meter, but the air-suction seed meter must be matched with the fan system. Not only is the structure complex and huge, the manufacturing cost is high, but also the power consumption is large, and the operating cost is increased.
