Drum type rice precise hill seeder

Abstract

The invention discloses a drum type rice precise hill seeder, which comprises seed boxes, walking wheels, furrowing devices, a drum device, a traction frame and seed conveying devices, wherein the drum device is arranged on the traction frame, and comprises a tube body; seed collecting openings are formed in the upper end surface of the tube body; a cover plate buckled with each seed collecting opening is arranged in each seed collecting opening position; seed discharging openings distributed at equal intervals are uniformly distributed in the outer circumferential surface of the tube body; a round baffle plate vertical to the axial direction of the tube body is arranged in the tube body between the adjacent seed discharging openings; the walking wheels synchronously rotating together with the drum device are arranged at two ends of the drum device; the seed boxes are arranged at the upper side of the drum device; the lower side of the drum device is provided with the matched seed conveying devices; the furrowing device is arranged at the bottom end of each conveying device. The drum type rice precise hill seeder has the advantages that the structure design is reasonable; rice seeds are in square lattice distribution; rice seeds are enabled to be precisely sowed without damage; the mechanical structure is simple and reliable; the manufacturing cost is low; the popularization is convenient.

Description

[0001] Technical field: [0002] The invention relates to the field of agricultural planting machinery, and mainly relates to a drum-type rice precision hole sowing machine. [0003] Background technique: [0004] Rice is one of the main food crops in China, and occupies a pivotal position in my country's food production. With the reduction of the labor force, the traditional rice transplanting method is no longer suitable for the current production needs. Live broadcast, water live broadcast. However, these machines are expensive and the production operation costs are high. The habit of rice is that it likes ventilation and light transmission, so it has always been artificially planted and distributed in a grid pattern. Precision hole sowing of rice can increase yield. However, the surface of rice seeds is rough, with edges and corners, and some have thorns that are easily damaged. People have done a lot of research, mainly using air-suction rollers, but the precision of s...

Problems solved by technology

However, the surface of rice seeds is rough, with edges and corners, and some have thorns that are easily damaged. People have done a lot of research, mainly using air-suction rollers, but the precision of seeding is low, especially for hybrid rice with less seeding amount. 3-4 grains, the rice seeder currently used in production is difficult to meet the requirements
