Single-deck double-row seed sowing device

Abstract

The invention discloses a single-deck double-row seed sowing device, and aims to provide the single-deck double-row seed sowing device which is more accurate in sowing seeds and more stable in seed sowing performance. A seed separating box is arranged on the bottom part of a shell; an upper opening of a seed separating box body is downwards inclined relative to a direction of a seed sowing plate;two seed separating pipes are connected with a lower opening of the seed separating box in parallel; the seed separating box is provided with a seed separating tongue plate on a perpendicular center surface in a length direction of a rectangular body; the seed separating tongue plate upwards extend to a horizontal center line of the seed sowing plate; a seed baffling plate is arranged on a short side of the seed separating box body and is parallel to the seed separating tongue plate; the seed baffling plate upwards extend to penetrate through an inner ring seed absorbing hole circumference line; a side of the seed baffling plate is attached to a seed absorbing surface of the seed sowing plate; a seed cleaner is arranged above the horizontal center line of the seed sowing plate, and is located on one side of an upward rotating direction of the seed sowing plate. The single-deck double-row seed sowing device provided by the invention is applicable to being matched with a double-row seeder on a ridge for use.

Description

Technical field [0001] The invention relates to a seed metering device for a planter, in particular to a single-disk double-row seed metering device. Background technique [0002] The performance of the metering device of the traditional pneumatic field planter can meet the high-speed single-row planting on the ridge. In order to realize the double-row seeding of soybeans and corn on the ridge, the manufacturers have implemented the metering device of the existing pneumatic planter Technical improvement, some technical solutions are to directly use the existing single-row seeding disk, that is, a circle of seed suction holes is provided on the seeding disk along the circumferential direction, and then the discharged seeds are forced to be discharged through the seeding tube arranged under the seeder The shunt is planted according to two channels, and then two rows of seeding are realized. In order to ensure that each seed suction hole only sucks one seed, a plate-type seed clean...

AI Technical Summary

Problems solved by technology

In order to ensure that each seed suction hole only sucks one seed, a plate-type seed clearing knife is mounted on the seed metering plate, which can only realize one-sided seed clearing of a circle of seed suction holes, so the problem with this technical solution is that the seed separation is not accurate. Accurate, seed cleaning is not thorough enough, resulting in missed sowing and reseeding; there is also a technical solution to set two rings of seed suction holes along the circumferential direction on the seed metering plate, and the two rings of seed suction holes correspond to a seed drop tube respectively. It can solve the problem of seed separation, but still use the plate type seed clearing knife to complete the seed clearing scheme of two circles of suction holes, which also makes the seed clearing not thorough enough

Missed sowing and reseeding still exist, and there are stability problems in seeding performance, which directly affect the operation quality of the seeder
