Hole eye tangent vibration type seed feeding method and device

Abstract

The invention discloses a hole eye tangent vibration type seed feeding method and a hole eye tangent vibration type seed feeding device and relates to the field of sowing machines. The hole eye tangent vibration type seed feeding device is the seed feeding part of a sowing machine. The smooth surface of the seed feeding part has a plurality of seed like hole eyes which are bigger than seeds; the surface of the seed feeding part is inclined with the hole eye surface upward and is buried in seeds in a seed feeding chamber; the seed feeding chamber and the seed feeding part vibrate tangently along a hole eye mouth face, and the amplitude and frequency of the vibration are high enough to promote the seeds on the surface of the seed feeding part to slide; the seed discharging part moves up along the direction of the tangent of the surface and moves out of the seed feeding chamber from the hole eyes; and each hole eye is filled with one seed, and the outside of the hole eye mouth face has no seeds. If the difference between the sizes of the seeds is not big, a seed charging rate and a single seed rate both reach 100 percent and seeds are not damaged. The seed feeding method has high precision, ensures simple structure and easy operation and has high efficiency.

Description

1. Technical field [0001] The socket tangential vibration seeding method and device relate to the field of seeding machinery, in particular to the seeding parts on the seeder. 2. Background technology [0002] At present, the domestic and foreign sowing mechanical seeding methods mainly include nest wheel type (hole wheel type groove wheel type), sieve plate type, air suction type, electromagnetic type, clamp type, etc. These machines all have some drawbacks. For example, the nest-groove wheel type only uses the gravity of the seeds to fill the seeds, and the void rate, heavy seed rate, and seed damage rate are high; the air-suction type and electromagnetic type have complex structures, high cost, and many failures, and it is difficult to generate and maintain uniform and constant. The force field and the positioning accuracy of arranging seeds are not high; although the sieve plate type has high precision, it is troublesome to operate, cannot continuously sow seeds, and ha...
