The transplanting robot is the key equipment to realize the automatic transplanting of seedling trays, and the transplanting robot’s claw is an important part that comes into direct contact with seedlings, and its performance directly affects the quality of transplanting. Therefore, the development of stable and efficient transplanting mechanical claws is of great significance to improve the survival rate of transplanting robot and the efficient operation of transplanting machine.

[0004] The purpose of the present invention is to provide a high-speed transplanting mechanical claw, which is driven by a cylinder and electromagnetic actuator, with precise driving control and fast working speed, and can accurately and quickly complete the grasping and releasing action of seedlings, in response to the shortcomings of the prior art.

[0005] The purpose of the present invention is achieved by the following technical solution: a high-speed transplanting mechanical claw, comprising a main frame, a cylinder 1, an electromagnetic pusher 5, and a grasping mechanism; said pusher part of the cylinder 1 is fixed on an upper fixing plate; said electromagnetic pusher 5 is fixed on a lower fixing plate in the main frame, and said mechanical claw mounting bracket is fixed on the main frame.

[0006] Said main frame is of upper and lower frame structure, divided into upper fixed limit 2 plate, upper and lower limit plate connecting bolts 8, lower fixed limit plate 4, bolts, nuts and other components. The upper fixed limit plate 2 is fixedly connected to the cylinder push rod 10. The upper limit plate 2 and lower limit plate 4 are fastened by bolts and nuts through the upper and lower limit plate connecting bolts 8. The lower limit plate 4 is fixed to the electromagnetic actuator 5 and is hinged to the four surrounding small cylinders 3 by the small cylinder swing connector 9.

[0007] Said grasping mechanism consists of six parts, divided into electromagnetic push rod 4, small cylinder swing connection 9, piece 9 rod and piece 12 of the connecting rod 15, small cylinder 3, plate steel pin sleeve 7, plate steel pin 6 composition.

[0008] Further, the electromagnetic push rod 5 is hinged to the connecting rod 15 of the piece 9 rod to the piece 12, and the small cylinder swing connection 9 is fixed at the small cylinder 3, thereby driving the small cylinder 3 to swing around the frame and drive the plate steel needle 6. The plate shaped steel needle sleeve 7 is set on the plate shaped steel needle 6 to facilitate disengaging the plate shaped steel needle 6 when the transplanting of the transplanted seedling is completed.

[0010] The present invention has a beneficial effect: the overall size of the transplanting mechanical claw of the present invention is small, and the grasping is accurate and rapid. Pneumatic cylinder 1 can accurately and quickly output the distance, so as to accurately and quickly drive the frame to the designated position and improve the working speed. The electromagnetic actuator 5 controls the clamping action, which can control the force of the plate-shaped steel needle 6 on the transplanting object to better protect the transplanting object and is more conducive to high-speed transplanting. At the same time the plate shaped steel needle 6 opening size can be controlled by signal, so that the mechanical claw can be applied to different types of seedling tray.
