Whole-row seedling taking manipulator assembly of automatic transplanting machine

Abstract

The invention relates to a whole-row seedling taking manipulator assembly of an automatic transplanting machine. The manipulator assembly comprises a transmission device and a seedling taking device, wherein the transmission device comprises a base, a moving cylinder, a rocker, a turning cylinder, a fan-shaped swinging block and a rack; the seedling taking device is mounted on the rack and comprises a gathering and dispersing cylinder, a cylinder support, a cylinder pull ring, a horizontal sliding rail, a sliding blocks II, mounting plates, seedling taking cylinders, motor fixing bases, rotating motors, conical spring seedling needles, seedling separation plates and a metal chain. With the adoption of the manipulator assembly, a whole row of seedlings can be taken once, the structure is simple, the operation efficiency is high, the matrix of tray seedlings can be protected better, and the survival rate is increased during transplanting.

Description

technical field [0001] The invention relates to a manipulator for taking seedlings in a row of an automatic transplanting machine. Background technique [0002] At present, in agricultural transplanting and planting, the effect of the manipulator for taking seedlings is to take seedlings at the seedling picking station, move to the seedling putting station to put the seedlings, and constantly repeat the above actions to realize automatic seedling picking. In field transplanting operations, there are high requirements for transplanting efficiency and transplanting quality. According to the current domestic and foreign data, most of the mechanical structures used are seedling picking manipulators with slide rails. Compared with the current seedling tray specifications , the size of a single mechanism is large, even if they work side by side, the number of seedlings taken by the slide rail seedling picking manipulator is small each time, and the transmission efficiency of the s...

In field transplanting operations, there are high requirements for transplanting efficiency and transplanting quality. According to the current domestic and foreign data, most of the mechanical structures used are seedling picking manipulators with slide rails. Compared with the current seedling tray specifications , the size of a single mechanism is large, even if they work side by side, the number of seedlings taken by the slide rail seedling picking manipulator is small each time, and the transmission efficiency of the seedling picking manipulator with slide rails is low; although the transmission efficiency of the non-circular gear seedling picking manipulator is relatively low High, but the structure of the mechanical system is complicated, the movement precision is high, and it only takes seedlings from a single plant; for the cylinder automatic seedling picking manipulator developed in Europe and the United States, although the pneumatic seedling picking hand can quickly achieve seedling picking, most of them use the clamping method to pick seedlings , In the process of clamping, there will be damage to seedlings and damaged substrates, which will affect the survival rate of planting and reduce the efficiency of transplanting, and the pneumatic system is more complicated, the manufacturing cost is relatively high, and the mechanical fault diagnosis is complicated
