Multi-row slot-hole-wheel-type precise rape seeding device

Abstract

The invention belongs to the technical field of seeding devices of agricultural mechanical seeders. A multi-row slot-hole-wheel-type precise rape seeding device comprises a seed protecting device, a seeding roller, a seeding shaft, a seed emptying wheel, a seed emptying shaft, a seed box, a seeding device shell, a seed pushing steel wire, side plates, a seeding device bracket and a seed feeding opening, wherein the seeding roller is in key connection with the seeding shaft; the seeding shaft is arranged on bearing seats on a left side plate and a right side plate; the seed emptying wheel is in the key connection with the seed emptying shaft; the seed emptying shaft is arranged on the bearing seats on the left side plate and the right side plate; the seed box is positioned on one side of the seeding roller and is connected on the left and right side plates; the lower side of the seed box is provided with a seed roller in a closely contact way; the seeding device shell is positioned above the seeding device and is arranged on the left and right side plates through bolts; input power drives the seeding shaft through chain drive; the power on the seeding shaft is transmitted to the seed emptying shaft after changing speed through a pair of drive chain wheels; and the seed protecting device moves automatically under the action of the friction force of the seeding roller. The multi-row slot-hole-wheel-type precise rape seeding device has the characteristics of novel design, compact structure, four rows of one device, adjustable seeding height and low seed breakage rate.

Description

technical field [0001] The invention relates to the technical field of seed metering devices in agricultural seeding machines, in particular to a multi-row grooved hole wheel type precision seed metering device for rape. Background technique [0002] The traditional cultivation methods of rapeseed are: plowing, ditching and ridge building, basal fertilizer application, direct sowing or transplanting, field management, and harvesting. This planting method has many procedures, high labor intensity, waste of seed fertilizer, and low economic benefits. Therefore, the mechanized planting of rape has been paid more and more attention. At present, the seed metering devices used in precision sowing of rapeseed mainly include mechanical type and pneumatic type. The main disadvantages of the mechanical precision seed metering device are high seed breakage rate and serious hole blockage; the main disadvantages of the pneumatic seed metering device are the high processing accuracy req...
