Problems solved by technology

[0004] The transplanting claws developed at this stage are mainly driven by cylinders. For example, the invention patent of a stem-grasping plug seedling transplanting claw (CN103797946A) requires an additional compressed air source, which is difficult to miniaturize and is difficult to use in self-propelled robot
At the same time, this type of transplanting claw also has the disadvantages of large vibration, low precision and poor adaptability

Abstract

The invention discloses an electric mechanical claw for transplanting seedlings of a seeding tray. The electric mechanical claw comprises a main body frame, a steering engine, a steering engine mounting bracket, a coupling and a transmission shaft, four incomplete bevel gear rocker arms, a connecting rod, a steel needle, a mechanical claw mounting bracket and a support shaft, wherein the steering engine is arranged on the main body frame through the steering engine mounting bracket; the four incomplete bevel gear rocker arms are arranged on the main body frame through shafts; the steering engine drives the four incomplete bevel gear rocker arms to move through the coupling and the transmission shaft, and drives the connected four-bar mechanism to move, so that the steel needle mounted on a four-bar linkage acts to finish the seedling clamping or loosening operation. The electric mechanical claw is suitable for transplanting the seedlings of the seeding tray, and is driven by virtue of the steering engine; the clamping action can be accurately controlled; and the electric mechanical claw has good adaptability on different types of seedling trays and seedlings.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and relates to an electrically driven seedling tray seedling transplanting mechanical claw, which is mainly used as an end effector of a transplanting robot and is used for gripping and transplanting objects. Background technique [0002] In the process of raising seedlings in the seedling tray, there are missing sowing or stunted seedlings in individual acupoints in the seedling tray, and it is necessary to grab healthy seedlings from the spare seedling tray and transplant them to these acupoints. At present, the transplanting of domestic seedling trays is mainly done manually. Workers need to transplant healthy seedlings from the spare seedling trays to the missing seedling positions on the working seedling trays one by one. The working environment is harsh, the labor intensity is high, and the work efficiency is low. It is difficult to realize large-scale operations, which restricts the d...
