Multi-seedling taking manipulator of automatic tomato transplanter

Abstract

The invention relates to a multi-seedling taking manipulator of an automatic tomato transplanter. The multi-seedling taking manipulator comprises a drive mechanism and seedling taking manipulator bodies, wherein the drive mechanism comprises a first motor, a second motor, a second motor fixing shaft sleeve, a large disc, a small disc, an upper screw rod, a lower screw rod and a screw rod coupling; the seedling taking manipulator bodies are arranged on the upper screw rod and the lower screw rod; each seedling taking manipulator body comprises an ejector rod 8-shaped cam, a press plate spring clamp, a press plate pull-up spring, a seedling taking fork, a T-shaped slider, a wedge-shaped spring clamp shaft sleeve, a seedling taking fork ejector rod reset spring, a wedge-shaped contact surface moving spring, a wedge-shaped slide spring clamp, a seedling taking fork ejector rod, a wedge-shaped slide spring clamp mounting shaft sleeve, a wedge-shaped slide spring clamp mounting shaft, a spring clamp positioning shaft sleeve, a fixed shaft sleeve mounting bearing, a T-shaped groove and a press plate spring clamp 8-shaped cam. The multi-seedling taking manipulator of the automatic tomato transplanter can take multiple seedlings simultaneously, is simple in structure and low in manufacturing cost, and can increase seedling taking efficiency of field transplanting.

Description

technical field [0001] The invention relates to a multi-plant seedling picking manipulator of an automatic tomato transplanting machine. Background technique [0002] At present, in agricultural transplanting and planting, the role of the seedling picking manipulator is to pick up the pot seedlings on the seedling tray of the transplanting machine and transfer them to the position where the seedlings are released. For field transplanting operations, it has a high impact on the transplanting efficiency. According to the current domestic and foreign data, for the transplanting machine developed by Japan, the mechanical structure of this device is complicated, debugging is difficult, there are many mechanical failures, the mechanical operation is not stable enough, the efficiency is low, and the lubrication is difficult. .

[0002] At present, in agricultural transplanting and planting, the role of the seedling picking manipulator is to pick up the pot seedlings on the seedling tray of the transplanting machine and transfer them to the position where the seedlings are released. For field transplanting operations, it has a high impact on the transplanting efficiency. According to the current domestic and foreign data, for the transplanting machine developed in Japan, the mechanical structure of this device is complex, debugging is difficult, there are many mechanical failures, the mechanical operation is not stable enough, the efficiency is low, and the lubrication is difficult.

For the cylinder automatic seedling picking manipulator developed in Europe and the United States, although the pneumatic seedling picking hand can quickly realize seedling picking, the pneumatic system to realize this function is relatively complicated, the manufacturing cost is relatively high, and the mechanical fault diagnosis is complicated.
