Seedling delivery device of pot seedling transplanter

Abstract

The invention discloses a seedling delivery device of a pot seedling transplanter. The seedling delivery device comprises a seedling box assembly, a seedling plate toothed belt delivery mechanism, a longitudinal seedling delivery mechanism and a transverse seedling delivery mechanism, wherein the transverse seedling delivery mechanism is formed by a pair of non-circular gear transmission and spiral transmission, a driving gear fixed on a power input shaft is meshed with a driven gear fixed on a spiral shaft, a spiral chute in the spiral shaft is internally provided with a slider assembly fixedly connected with the panel of a seedling box, one end of the spiral shaft is fixedly provided with a shifting lever, the shifting lever pushes a power input piece oscillating bar of the longitudinal seedling delivery mechanism via a shifting lever roller at the tail end, the oscillating bar is fixedly arranged at the left and right ends of an oscillating bar shaft, one end on the left side of the oscillating bar shaft is fixedly provided with a driving bar of a four-link mechanism, and a toothed belt is driven or locked to delivery the seedling plates downwards via a pair of opposite ratchets coaxially mounted with a driving pulley axle. The seedling delivery device disclosed by the invention can realize transverse seedling delivery with non-uniform velocity, and the pair of opposite ratchets is adopted to drive the pulley, so that the pulley can be precisely driven to rotate, the ratchet can be locked bidirectionally, and thus the precise delivery of the seedling plates is ensured.

Description

technical field [0001] The invention relates to a seedling delivery device of a rice transplanter, in particular to a seedling delivery device of a pot seedling transplanter. Background technique [0002] Pot seedlings are a kind of seedlings raised in pots and pans, usually used on transplanting machines and swinging machines. The seedlings are taken out of the hole trays and planted into the soil through the pulling out or ejection of the mechanical structure, and 1-2 plants can be achieved. The precision and thin planting can be applied to the planting of super rice. During the planting process, the roots of the seedlings are not torn, so the seedlings are not damaged, and the seedling slowing period is short, and pot seedling transplanting has the advantage of increasing production. [0003] At present, the seedling delivery device of the existing pull-out pot seedling transplanter often adopts chain transmission, which is complicated in structure and not easy to assemb...

AI Technical Summary

Problems solved by technology

[0003] At present, the seedling delivery device of the existing pull-out pot seedling transplanter often adopts chain transmission, which is complicated in structure and not easy to assemble. It is also very troublesome to adjust and maintain in daily use. The complex structure also makes it unfavorable to realize modular production.

In addition, the horizontal seedling delivery of the existing seedling delivery device uses a uniform-speed moving box scheme. Since the seedling box is always in a relatively fast moving state during the seedling picking process, it is not conducive to the seedling picking mechanism to accurately take out the seedlings from the seedling tray. The problem of wrongly picking pot seedlings leads to the lack of seedlings when transplanting pot seedlings in the field, which affects the yield; and the current vertical seedling feeding device is not reliable when it works at high speed, often stuck, unable to send seedlings accurately, and skipping teeth And other problems, can not meet the needs of high-speed transplanting
