High-speed precise-sowing vegetable seed discharging device with combined structure cell wheel

Abstract

The invention provides a high-speed precise-sowing vegetable seed discharging device with a combined structure cell wheel. The device comprises a seed storage box and the combined structure cell wheelarranged in the seed storage box, one or more combined structure cell rings are axially arranged on the outer cylindrical face of the combined structure cell wheel, multiple combined structure cellswhich are arranged in sequence in the circumferential direction are arranged in the combined structure cell rings, seed filling slide ways, seed filling transition circular arc faces, inner circular arc cell holes, seed returning transition circular arc faces and seed returning slide ways are sequentially connected inside the combined structure cells in the outer circumference direction of the combined structure cell wheel, the openings of the inner circular arc cell holes are rectangular, the bottom faces of the inner circular arc cells are circular arc faces, the inner circular arc cell holes are located in the middles of the combined structure cells, the seed filling slide ways and the seed returning slide ways are rectangular inclined walls which extend from the two ends of the combined structure cells to the two ends of the inner circular arc cell holes, and the bottom ends of the seed returning slide ways are higher than those of the seed filling slide ways. Under the condition of high-speed operation, the seed filling rate is high, the seed discharging device is low in sowing repetition rate and sowing missing rate, the variable coefficient of row spacing is small, and sowing uniformity is good.

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 diameter of small particle size seed is generally below 3mm, and according to incomplete statistics, the vast majority of vegetable seeds are small seeds, wherein the particle diameter of 85% vegetable seed is 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...

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
