Abstract

The invention relates to the field of agricultural machinery, in particular to an annular-slot type high-frequency vibration seeding unit, and overcomes the drawbacks of the prior small seed sowing machine caused by structural defects. The seeding unit comprises a machine frame and a seed box, wherein a seeding unit shell is arranged under the machine frame. The seeding unit shell has a seed inlet on the top, seed outlets at the bottom and a seeding shaft in the middle. The seeding unit shell is provided with seeding wheels. A fit clearance of the seeding unit shell and the seeding wheels is 0.10mm. Outer surfaces of the seeding wheels are provided with annular slots. Seed tubes corresponding to the seeding wheels one by one are arranged under the seed outlets. The seeding unit adopts a concentrated seeding mode to realize 'one-machine multi-row' seeding, is applicable to drill seeding and fine and small amount seeding of crop seeds with different grain diameters. The seeding unit hasthe advantages of improved seed filling and seed cleaning effects due to a high-frequency vibrator, smart and simple structure contributing the reduction of the weight of a seeding machine, uniform seeding, stable seed quantity, good commonality and good popularization and application prospects.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a ring-groove type high-frequency vibration seed metering device suitable for small-scale seeding operations of grass seeds, millet, sorghum, wheat, beans, corn and other crops. Background technique [0002] At present, known crop seed metering devices include three categories: sowing seed metering device, drill seed metering device and point (hole) sowing seed metering device. , conical hole plate type, centrifugal type, pendulum type, spoon type, brush type and other types, this kind of seed metering device is generally suitable for seeding seeds with a particle size greater than 3.5mm, and it is difficult to meet the requirements of grass seeds, millet, and millet. The requirements for seeding of small-grain crops are mainly as follows: ①The fit gap between the parts of the above-mentioned seed metering device is relatively large, and small-grained seeds are easy to enter...
