Seed metering apparatus applicable to precise small-quantity seeding of small-granule seeds

Abstract

The invention relates to a seeding apparatus of agricultural machinery and provides a seed metering apparatus applicable to precise small-quantity sowing of small-granule seeds. The apparatus can arrange seeds into a line and sow the seeds in sequence. The apparatus comprises a seed filling box, a seed restricting separator plate, seed metering separation blades, a seed filling groove, a seed clearing piece, a hairbrush and a seed clearing slit, wherein the seed filling groove is an annular groove which can arrange seeds into a line, the seed restricting separator plate restricts the amount of seeds above the seed filling groove, reduces extrusion force on seeds and decreases the damage rate of seeds, the seed metering separation blades are low, which facilitates seed filling, the hairbrush is used to reduce damage to seeds, gaps are arranged between the hairbrush and the seed metering separation blades, so shearing force on seeds is reduced, and the seed clearing piece prevents seeds from being stuck in the seed filling groove, thereby preventing miss-seeding.

Description

technical field [0001] The invention relates to a sowing device in an agricultural machine. Background technique [0002] Precision sowing can arrange seeds reasonably, save seeds, make rational use of land, sunlight and wind, obtain a good growth environment, coordinate the relationship between individuals and groups, and achieve high spike rate, more spikes, more grains, and fullness per plant, so that achieve the goal of high yield. Precision sowing cultivation technology can only be put into practice on a large scale with the help of seeders with excellent performance. Precision sowing mechanization technology has the advantages of seed saving, labor saving, energy saving and high yield. Wheat is one of the main food crops in my country. The sowing rate of wheat is large and the spacing between plants is small. Due to the limitation of filling time, the existing wheat precision metering device has low seeding speed and high crushing rate. Now the commonly used seed me...

AI Technical Summary

Problems solved by technology

The sowing rate of wheat is large and the distance between plants is small. Due to the limitation of filling time, the existing wheat precision seed metering device has low seeding speed and high breakage rate. Now the commonly used seed metering device for wheat seeder is grooved wheel seed metering device.

However, due to the structure of the grooved wheel seed meter, when the seeding amount is small, the seed flow is pulsating, and the uniformity is affected
