The invention relates to an external formed-hole wheel equipped on a hole-pricking and seed-sowing single unit and belongs to agricultural machinery. The external formed-hole wheel consists of a small-diameter cylindrical body and a large-diameter cylindrical body which are coaxial, wherein the small-diameter cylindrical body has the diameter size of 145mm and the axial length of 35mm, and the large-diameter cylindrical body has the diameter size of 164.5mm and the axial length of 22mm; and a seed charging introduction guiding groove and a seed charging external formed hole are formed in the circumferential surface of the large-diameter cylindrical body, a driving power splined hole and a seed-sowing driving pin shaft hole are separately formed at circumferential parts, where diameters are 100mm and 80mm separately by taking the center point of circumference of the external formed-hole wheel as a center of circle, and an included angle between the counterclockwise direction of the center of the seed charging external formed hole and the circumferential direction of the center of the seed-sowing driving pin shaft hole and an included angle between the counterclockwise direction of the center of the seed charging external formed hole and the circumferential direction of the center of the driving power splined hole are 100 degrees and 210 degrees separately. The wheel is novel and simple in structure, and the determination of technical parameters is scientific and reasonable; and by equipping the wheel on the formed-hole-type hole-pricking and seed-sowing single unit, the hole-pricking operation and the seed-sowing operation are good in synchronism, the seed-sowing precision is high, and the use is reliable.
Description
technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a shape hole wheel on a hole-piercing seed metering device. Background technique [0002] The agronomic method based on hole sowing and row seeding has the characteristics of small soil disturbance and low energy consumption. This method has been tried in the sowing operation of dry farming. However, the existing hole sowing seed metering devices have technical problems such as poor hole quality, low hole formation efficiency, strict requirements on seed size, poor synchronization between hole pricking and seeding, and easy soil accumulation in hole formation. Therefore, the applicant researched and designed a new structure hole-type seed-discharging monomer, which preliminarily solved some problems of the above-mentioned prior art. However, there are still problems of poor synchronization between hole piercing and seeding, and the accuracy of seeding needs to be improved. The key ...
