Abstract

The invention relates to a synchronous air suction type rice breeding seed-metering device which comprises a main frame, a flange shaft, a rotary air chamber and a seed falling device; one end of the main frame sleeves the outer side wall of the flange shaft, and the other end of the main frame is detachably provided with a cover door; the rotary air chamber is fixedly arranged in the main frame, the flange end of the flange shaft penetrates into the rotary air chamber, the outer side wall of the flange shaft is sleeved with a driven chain wheel, the driven chain wheel is fixedly connected with the rotary air chamber, and an opening is formed in the position, corresponding to the driven chain wheel, of the main frame; the end part, far away from the flange end, of the rotary air chamber is open, and a seeding disc is detachably arranged at the open end; the main frame, the cover door and the seeding disc form a closed seed chamber; a seed falling inlet and a seed discharging opening which penetrate into the seed chamber are formed in the outer wall of the main frame at intervals, and the seed falling device is fixedly arranged at the seed falling inlet; a plurality of seed suction holes are formed in the seeding disc; and the flange shaft is communicated with an external wind power source, and an air breaking device is arranged at the position, corresponding to the seed discharging opening, of the flange end.

Description

technical field [0001] The invention relates to a synchronous air-suction seed metering device for rice breeding, which belongs to the technical field of agricultural machinery. Background technique [0002] Rice is the main food crop in China. New rice varieties are bred every year in China. However, rice breeding in my country mainly adopts the method of artificial breeding for sowing. Rice breeding requires testing thousands of varieties each time. Manual sowing is labor-intensive, labor-intensive and time-consuming, the uniformity of seedling emergence is poor, and it is greatly affected by external interference factors, which directly affect the accuracy of breeding experiments. At present, there is no mature rice breeding metering device developed for the domestic market in the domestic market. In addition, the shape and size of rice varieties in my country vary greatly, and seeds with large differences in different regions and appearances need to replace the sowin...
