The following is a brief description of the operation of the present invention.
As shown in fig. 3, 4 and 5, plug seedlings were interposed between the ends of the seedling claws I and II before seedling throwing. The power source is input by the rotating shaft to drive the cam to rotate. When the tail end of the seedling claw I and the tail end of the seedling claw II reach a seedling throwing point for throwing seedlings, the convex part of the cam is contacted with the push rod to push the push rod to move towards the spring sleeve, the push rod drives the right-angle connecting rod to move towards the spring sleeve, and then the right-angle connecting rod drives the connecting shaft to move towards the spring sleeve along the guide groove; the seedling claw I and the seedling claw II can rotate around the fixed shaft, when the connecting shaft drives one end of the connecting rod I and one end of the connecting rod II to rotate around the connecting shaft, one end of the seedling claw I and one end of the seedling claw II which are connected with the pin shaft I and the pin shaft II synchronously move outwards, the other end of the seedling claw I and the other end of the seedling claw II simultaneously move outwards, plug seedlings are loosened, and plug seedling throwing is completed; namely, once the convex part of the cam is contacted with the push rod, the seedling claws I and II are opened outwards, so that the plug seedlings are loosened; the rotating shaft continues to rotate, the convex part of the cam continues to be contacted with the push rod, and the seedling claw I and the seedling claw II are kept in an open state. As shown in fig. 6 and 7, as the rotating shaft rotates, the cam rotates past the protruding position at a certain moment, the push rod is constantly contacted with the outer contour of the cam under the action of the elastic force of the spring, so that the push rod moves towards the cam direction, the connecting shaft is immediately driven to move towards the cam direction in the guide groove, the connecting shaft drives one ends of the connecting rod I and the connecting rod II to rotate around the connecting shaft, the seedling claw I and one end of the seedling claw II of the connecting pin shaft I and the connecting pin shaft II synchronously move inwards, and the other ends of the seedling claw I and the seedling claw II simultaneously move inwards. Along with the rotation of the rotating shaft, when the arc part of the cam is contacted with the push rod once, the tail ends of the seedling claws I and the seedling claws II move inwards to the minimum distance, the distance between the seedling claws I and the seedling claws II is equal to the diameter of the plug seedling stem, and at the moment, the seedling taking claws reach the positions of the plug seedlings to clamp the plug seedlings to finish the seedling taking and clamping actions. The arc part of the cam keeps in contact with the push rod under the action of the elastic force of the spring along with the rotation of the rotating shaft, the push rod is static, the distance between the tail ends of the seedling claw I and the seedling claw II is unchanged, the plug seedlings keep in a clamping state until the protruding part of the cam is in contact with the push rod, the tail ends of the seedling claw I and the seedling claw II move outwards simultaneously, and the plug seedlings are loosened. The position of the adjusting baffle plate 19 on the push rod can adjust the elasticity of the spring, namely the thrust borne by the push rod, namely the clamping force between the tail ends of the seedling claw I and the seedling claw II is adjusted, so that the elastic adjustment of the clamping force borne by the plug seedlings under the action of the spring is ensured, and the damage of the plug seedlings is reduced.
The above description is only for the specific embodiments of the present invention, and the changes that can be easily conceived by those skilled in the art within the scope of the present invention should be covered within the protection scope of the present invention.
