Embodiment Construction

[0036] The tilting disc type small grain fine seed metering device of the present invention comprises a seed box 1, a seed filling chamber casing 2, a seed quantity regulating plate 3, a seed filling tray 5, a seed metering device housing 7, a seed metering tray 10, a Seed device axle 11. The seed meter housing 7 is installed on the seeder with an inclination of 30°-60°; the seed metering disc 10 and the seed filling disc 5 are successively installed below and above the seed meter housing 7 through the seed meter shaft 11, and the seed filling chamber cover A seed filling chamber 4 is formed between the shell 2 and the seed filling disc 5 , and a seed box 1 and a seed feeding volume regulating plate 3 are arranged above the seed filling chamber cover 2 . The seed-filling tray 5 is provided with a seed-filling hole 16, an upper surface 17 of the seed-filling tray, an upper boss 18 of the seed-filling tray, a lower boss 19 of the seed-filling tray, and a groove 20 of the seed-fi...

Abstract

The invention discloses an inclined disk type small seed small-amount seed sowing device. The inclined disk type small seed small-amount seed sowing device comprises a seeding box, a seed filling room case, a seed entering quantity adjusting plate, a seed filling disk, a seed sowing device shell, a seed sowing disk and a seed sowing device shaft. The seed sowing device is installed on a seed sowing machine in a mode of inclining 30 to 60 degrees. The structures of the seed filling disk and the seed sowing disk are utilized, the whole seed sowing process is divided into four steps of seed filling, seed cleaning, seed inputting and seed sowing, the seeds are guaranteed to be sowed in the lowest position, the seed sowing height is lowered, the time on seed sowing is shortened, and seeds per bunch and intervals can be guaranteed effectively; according to the inclined disk type small grain small-amount seed sowing device, seed filling is conducted softly and automatically depending on the gravity, seed cleaning is conducted softly and automatically by utilizing the gravity, a seed cleaning brush is arranged, few seeds clamped in seed filling holes can be brushed down, and seed clamping and seed damaging are avoided; the seed filling disk and the seed sowing disk are exquisite in structure and are both provided with two bosses, positioning with rolling bearings is reliable, fit clearance with the seed sowing device shell can be guaranteed, friction with the seed sowing device shell is avoided, and the service life of the seed sowing device is prolonged greatly.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, and mainly relates to an inclined disc type small-grain precision and small-quantity seed metering device suitable for sowing small-grain seeds of millet, millet, sorghum, rape, flax, alfalfa, etc. Background technique [0002] At present, the common sowing methods include sowing, drilling, and point (hole) sowing, and correspondingly there are broadcast seeders, drill seeders, and point (hole) seeders. The drill seeders used in agriculture have outer grooves. Wheel type, inner groove wheel type, grinding disc type, cone type hole disc type, pendulum type, centrifugal type, spoon type and brush type, etc., but this type of sowing method does not care about the seed spacing, so it is difficult to meet the precise amount sowing requirements. The point (hole) seeding device is used for crop seeding or single-grain precision on-demand. During hole-seeding, the seed-metering device dis...
