Detailed ways

The structure, principle and working process of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but the protection scope of the present invention is not limited thereto.

When transplanting seedlings in the plug tray, the piston rods at both ends of the two-way cylinder 2 stretch out, and the parallel push rod 33 fixedly connected with it slides along the guide rail of the beam 11 of the support 1 to both ends of the beam, and the planting arm 3 moves toward the two ends of the beam. movement, and drive the planting duckbill 4 to rise to the position of receiving seedlings. At this time, the planting duckbill 4 is closed under the action of the closed cylinder 5; Retract, drive the parallel push rod 33 to move in the opposite direction along the beam 11 slide rail, and drive the planting duckbill 4 to move downward through the planting arm 3, and at the same time close the cylinder 5 to drive the planting duckbill 4 to open under the action of the integrated coordination controller Put down the plug seedlings to realize the action of punching hole seedlings; after the planting duckbill 4 puts down the plug seedlings, the two-way cylinder 2 drives the planting arm 3 to drive the planting duckbill 4 to move upward, and the lowest point of the planting duckbill 4 is higher than the plug seedlings When the height is at a certain distance, the closed cylinder 5 drives the planting duckbill 4 to close under the action of the integrated coordination controller, and is ready to receive the next plug seedling; this cycle in turn completes the transplanting operation of the plug seedlings.

Seedling clamping and seedling banding are problems that are difficult to overcome when the mechanical cam controls the closure of the planting duckbill, especially when the plug seedlings are transplanted at high speed. In order to avoid the problem of clamping seedlings with seedlings caused by the premature closure of the planting duckbill 4, the present invention deliberately uses the integrated coordination controller with the help of program control to make the planting duckbill rise to a certain distance higher than the plug seedlings and then close it; at the same time, the present invention uses The auxiliary closing spring accelerates the closing speed after planting duckbill seedlings to ensure the success rate of inoculation of the next plug seedling; and under the action of the integrated coordination controller, the planting mechanism of the present invention has the actions of throwing seedlings-grabbing seedlings-punching holes-planting seedlings More coordinated and efficient.
