V-groove driving wheel type seed guiding device

Abstract

The invention relates to a V-groove driving wheel type seed guiding device, which belongs to agricultural machinery. The V-groove driving wheel type seed guiding device mainly comprises a seed-metering unit assembly, a driving system comprising a variable-frequency controlled motor and an electrically controlled transmission shaft, and a seed guiding system comprising a V-groove brachistochrone seed guiding tube and a flexible seed-driving wheel. The V-groove driving wheel type seed guiding device adopts the flexible seed-driving wheel to carry out even seed distribution, the V-groove brachistochrone seed guiding tube to carry out delivery and seed guiding and the variable-frequency controlled motor to drive the electrically controlled transmission shaft and the flexible seed-driving wheelto rotate in real time, the instantaneous horizontal relative velocity of a seed dropping into a seed furrow is decreased or counteracted by a secondary seed delivery method, the moving track, speedand direction of the seed in the seed guiding tube are controlled before the seed gets into the soil of a seedbed, consequently, the stable delivery of seeds is realized, the problems existing in theprior art, such as severe bouncing as the result of the collision between seeds and the tube wall and poor evenness and stability of seed delivery, are overcome, and the V-groove driving wheel type seed guiding device has the characteristics of novel and reasonable structural design, good seeding operation quality, high automation degree and wide application range.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to a mechanical seed guiding assembly. Background technique [0002] The existing seed introduction tubes are mainly metal roll tubes, stretchable plastic tubes and arc tubes. Due to the defects of the seed introduction tubes, unreasonable design, and irregular manufacture, the occurrence of irregular and difficult occurrences between the seeds and the tube wall Controlled multiple collisions. After the grains are discharged from the seed metering device, they rely on their own gravity to fall freely. During the delivery process before being sown into the soil of the seedbed, the grains collide with the tube wall and bounce severely, and the movement in the tube is relatively random. The bed is irregularly arranged, and the overall seeding uniformity and stability are poor, which greatly reduces the quality of field seeding operations.

[0002] The existing seed introduction tubes are mainly metal roll tubes, stretchable plastic tubes and arc tubes. Due to the defects of the seed introduction tubes, unreasonable design, and irregular manufacture, the occurrence of irregular and difficult occurrences between the seeds and the tube wall Controlled Multiple Collisions

After the grains are discharged from the seed metering device, they rely on their own gravity to fall freely. During the delivery process before being sown into the soil of the seedbed, the grains collide with the tube wall and bounce severely, and the movement in the tube is relatively random, resulting in the grains being in the seedbed. Irregularly arranged in the bed, the overall uniformity and stability of seeding are poor, which greatly reduces the quality of field seeding operations
