Film mulching seeder for seed coating belts

Abstract

The invention discloses a film mulching seeder for seed coating belts. The film mulching seeder comprises a machine frame, a coating belt support, a plow-share, a directional pinch roller, an earth leveler, a film roller, a film leveling roller, a film pinch roller and a hiller, wherein a connection part for traction is arranged at the front end of the machine frame, the coating belt support is arranged on the upper side of the machine frame, the coating belt support is used for supporting a coating belt disk, the plow-share, the directional pinch roller, the soil leveler, the film roller, thefilm leveling roller, the film pinch roller and the hiller are sequentially arranged on the lower side of the machine frame, a groove is formed in the directional pinch roller, and the groove is usedfor guiding the seed coating belts of the coating belt disk. The film mulching seeder disclosed by the invention can cultivate the seed coating belts with accurate grain numbers and distances into afarmland according a required distance and a required sowing depth.

Description

technical field [0001] The invention relates to the technical field of agricultural seeding machinery, in particular to a film-coated seeder for seed coating belts. Background technique [0002] Hole sowing is also called on-demand sowing. According to the required row spacing, hole spacing, number of holes and sowing depth, seeds are put into the hole at fixed points. It is mainly used for sowing of row crops: corn, cotton, peanuts, etc. Compared with drill sowing, hole sowing can save seeds, reduce thinning management after emergence, make full use of water and fertilizer conditions, and improve seed emergence rate and operating efficiency. [0003] Precision seeding is an advanced form of hole seeder, which is a method of sowing seeds into the soil according to the precise number of grains, spacing, row spacing, and sowing depth. The hole sowing seed meter is represented by the outer grooved wheel seed meter and the disc seed meter. [0004] The working principle of the...

AI Technical Summary

Problems solved by technology

[0006] The horizontal disc seed metering device has a simple structure and is more reliable when working at low speed (V=6~7km / h). The bouncing phenomenon occurs in the ditch, resulting in a decrease in the qualified rate of plant spacing

The disc of the vertical disc seed meter is generally installed coaxially with the ground wheel, the transmission mechanism is simple, the seeding height is low, but the seed filling area is small, and the seed filling performance is poor, so the speed should not be too fast, and the forward speed of the unit is low

The disk of the inclined disk seed metering device is installed obliquely relative to the ground, and the seed opening is at the lowest point of the disk. The seed filling area is large and the seeding height is low, but the transmission device is relatively complicated.
