A high-speed precision sowing vegetable seed metering device with combined structure socket and wheel

Abstract

The invention provides a combined structure socket wheel type high-speed precise sowing vegetable seed meter, which includes a seed storage box and a combined structure socket wheel arranged in the seed storage box. The outer cylindrical surface of the combined structure socket wheel is along the shaft There is at least one composite structure socket eye ring, and a plurality of composite structure socket holes arranged in sequence in the circumferential direction are arranged in the composite structure socket eye ring, and the composite structure socket holes are provided with sequentially connected filling holes along the outer circumference of the composite structure socket wheel. The seed slideway, the seed filling transition arc surface, the arc inner socket, the seed transition arc surface and the seed slide, the opening of the arc inner pit is rectangular, the bottom surface is an arc surface, and the arc inner pit Located in the middle of the socket of the combined structure, the seed filling slideway and the seeding slideway are rectangular oblique walls extending from the two ends of the socket of the combined structure to the two ends of the arc inner socket respectively, and the bottom of the seeding slideway is as high as At the bottom of the seed filling slideway, under high-speed operating conditions, the present invention has high seed filling rate, low rate of reseeding and missed seeding by the seed metering device, small variation coefficient of plant spacing, and good sowing uniformity.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a socket-wheel type high-speed precise sowing vegetable seed metering device with a combined structure. Background technique [0002] In recent years, with the increasing demand for vegetables, the cultivation of vegetables has developed to a large scale. Vegetable seeds have the characteristics of small particle size and irregular shape. In order to adapt to mechanized sowing, vegetable seed pelletization technology is becoming more and more mature. The particle size of small-sized seeds is generally below 3mm. According to incomplete statistics, most of the vegetable seeds are small-sized seeds, and 85% of the vegetable seeds have a particle size below 2.3mm. Realizing the mechanized sowing of vegetable seeds can greatly improve the sowing efficiency, reduce labor costs, and release a large amount of agricultural labor at the same time. The development of high-...

AI Technical Summary

Problems solved by technology

The feature of the seed meter is that the reasonable structure avoids the leakage of seeds, prevents the seeds from being stuck, and ensures the reliable realization of precise sowing. It only realizes precision sowing in a small speed range, and cannot meet the precision sowing of seeds with suitable particle sizes at higher speeds
