Problems solved by technology

[0003] The core working part of the mechanized precision hole direct seeding technology is the precision seed metering device. At present, mechanical seed metering devices are widely used in the market. For seeds with irregular shapes and poor population mobility, mechanical seed metering devices are easy to damage the seeds. The seed range and seeding height are generally not adjustable. For the seeding requirements of multiple seeds in one hole, holes and missed seeding are prone to occur, and the seeding consistency and hole formation need to be improved.

Abstract

The invention provides a side-filling front-throwing precise seeding device and a seeding method thereof. The side-filling front-throwing precise seeding device comprises a shell, a seeding wheel arranged in the shell and a rotating assembly used for driving the seeding wheel to rotate, wherein the rotating assembly comprises a rotating shaft and a bearing seat; the shell is fixedly arranged on the bearing seat, one end of the rotating shaft penetrates through the bearing seat and the shell and is fixedly connected with the center of the seeding wheel; the shell is provided with a cover platefor sealing the shell; one side of the cover plate, far away from the seeding wheel, is provided with a sealing plate and a seed box; one side of the seeding wheel, close to the seed box, is providedwith a plurality of seed inlets which can be communicated with the seed box; the seeding wheel is internally provided with an annular groove and a plurality of seed pockets arranged in the annular groove, and the shell is provided with a seeding positioning plate. The seeding scope and the seeding height of the seeding device can be adjusted, the seed pockets of the seeding wheel precisely form pits of the pockets, a gathering channel temporarily store multiple seed, the seeding consistency and cavitability are good, and the rate of cavitating and missing seeding is low.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding, in particular to a side-filling and positive-feeding precision seed metering device and a seed metering method thereof. Background technique [0002] Precision hole direct seeding technology refers to sowing seeds in holes in the field according to the agronomic requirements of crops, reducing the thinning operation of field management in the later stage, and making the seedlings uniform, uniform, and strong, creating a new environment for the growth of later crops. Reasonable field plant population structure is conducive to stable and increased production. [0003] The core working part of the mechanized precision hole direct seeding technology is the precision seed metering device. At present, mechanical seed metering devices are widely used in the market. For seeds with irregular shapes and poor population mobility, mechanical seed metering devices are easy to damage the seeds. T...
