Spoon belt pneumatic type seed sowing device

Abstract

The invention relates to a spoon belt pneumatic type seed sowing device which comprises a shell, a conveying mechanism and a seed sowing pipeline. The conveying mechanism is arranged in the shell, theseed sowing pipeline is arranged on the outer side of a seed dropping port at the right end of the shell, a baffle is vertically arranged on the upper surface of the inner side of the shell, the baffle can move up and down along the shell, the inner areas, below the baffle, of the shell are communicated with each other, the space of the shell on the left side of the baffle is a seed box area, andthe conveying mechanism is arranged below the inside of the shell on the right side of the baffle. The conveying mechanism is obliquely arranged, the right end of the conveying mechanism is higher than the left end of the conveying mechanism, the conveying mechanism is used for conveying seeds from the seed box area to the seed sowing pipeline through seed spoons, and a plurality of seed spoons are detachably arranged on the conveying mechanism. The mechanical seed sowing device integrates the advantages of a mechanical seed sowing device and a pneumatic seed sowing device, and is novel and compact in structure and low in manufacturing cost. By adopting the spoon belt pneumatic type seed sowing device, seeding of different species such as rice, wheat and corn and adjustment of seeding amount can be realized by replacing the seed spoons with different sizes and shapes, adjusting the rotating speed of a synchronous belt wheel and the like.

Description

technical field [0001] The invention belongs to the technical field of agricultural machinery, and in particular relates to a scoop belt pneumatic seed metering device. Background technique [0002] The precision seed meter is the core component of the precision seeder. Its function is to divide the seeds in the seed box or storage room into single grains and discharge them at regular intervals. Its characteristics and working performance directly affect the seeding quality. Existing seed meters are mainly divided into two categories: mechanical and pneumatic. The mechanical seed meter has strict requirements on the size and shape of the seed, the precision of the seed meter is low, the damage to the seed is serious, and it is difficult to achieve high-speed operation, but the structure is simple, the manufacturing cost is low, and the maintenance and replacement are convenient; The size and shape requirements are not strict, the adaptability is strong, and the damage to th...

AI Technical Summary

Problems solved by technology

At present, most of the mechanical seed metering devices use hole-shaped wheels, which have better adaptability to round seeds such as corn and soybeans, but are less effective for irregular seeds such as rice and wheat, mainly reflected in filling, The process of seed protection and clearing is difficult, and the rate of seed injury is high

At present, pneumatic seed metering devices are divided into air-suction seed metering devices, air-blowing seed metering devices, and pneumatic seed metering devices according to their working principles.
