Seedling feeding and planting device of transplanter

Abstract

The invention relates to the technical field of transplanters and discloses a seedling feeding and planting device of a transplanter. The seedling feeding and planting device comprises a planter bracket, wherein a seedling feeding tube mounting plate is fixedly mounted at the top of the planter bracket, a seedling feeding tube is fixedly mounted at the top of the seedling feeding tube mounting plate, a seedling receiving bucket mounting plate is movably mounted at the bottom of the planter bracket, and a movable door mounting plate is fixedly mounted at the left side of the seedling feeding tube. According to the seedling feeding and planting device of the transplanter, through arranging a planting cylinder, a planter is driven to do up-and-down planting movement by taking a true motion cylinder as driving power; and the structure is simple, coordinated matching among seedling feeding tube seedling feeding, planter downward pitting, upward seedling receiving and planter duckbill open-seedling-falling closed-seedling-receiving motions is achieved through controlling telescopic motions of the planting cylinder, a valve switching cylinder and a planter switching cylinder, the requirements on different planting plant spacings and planting frequencies can be met, and the disadvantages such as complicated structures and difficulty in adjustment resulting from plant spacing adjustmentby adopting the traditional mechanical transmission mode are overcome.

Description

technical field [0001] The invention relates to the technical field of transplanting machines, in particular to a seedling feeding and planting device for a transplanting machine. Background technique [0002] The transplanter is mainly composed of feeders, seedling guide tubes, seedling supporters, ditch openers and soil-covering pressing wheels and other working parts. After the seedlings are manually separated, the seedlings are put into the feeding cylinder of the feeder. When the feeding cylinder turns to the top of the seedling guide tube, the valve under the feeding tube opens, and the seedlings fall into the seedling guide tube by gravity, and the seedlings are introduced into the seedling ditch opened by the opener through the inclined seedling guide tube. With the support of the grid-type seedling supporter, the seedlings are in an upright state. [0003] According to a kind of transplanting machine proposed by the Chinese authorized invention CN201710421296.8, it...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a seedling feeding and planting device for a transplanting machine, which has the advantages of conveniently changing the plant spacing and adjusting the planting frequency, and solves the problem of changing the column spacing of the traditional self-propelled transplanting machine. The time is more troublesome, and complex mechanical mechanisms are required to complete, and the frequency of planting is difficult to change, which will affect the planting efficiency of transplanting
