Potted seedling clamper

Abstract

The invention relates to a clamper and aims at providing a potted seedling clamper which is adaptable to potted tray of diverse sizes, is simple in structure, low in cost and easy to control. The technical proposal is as follows: the potted seedling clamper comprises a plurality of clamp fingers and is characterized by comprising a cylinder-shape shell, the bottom of the shell is manufactured with a plurality of straight channels distributed in radial direction, and the clamp fingers are embedded into the straight channels one by one and hinged with the bottom of the shell; the upper half of the inner cavity of the shell is fixed with a cover plate horizontally, the cover plate is manufactured with a plurality of sliding ways which are opposite to the straight channels of the bottom of the shell and distributed in radial direction, the upper half of the clamp fingers penetrate up through the sliding ways one by one, and the top of the clamp fingers are all pressed by a spring and havethe potential energy moving towards the direction of the shell axial line; a stepping motor is installed below the cover plate, the output shaft of the motor is arranged downwards vertically, a cam is fixed at the output shaft, and the working face of the cam receives clamping of the plural clamping fingers from four directions.

Description

Seedling holder technical field The invention relates to a clamper, in particular to a clamper used for clamping various seedlings on an automatic crop grafting machine. Background technique In industrial seedling raising and automatic grafting operations, it is often encountered that a few seedlings grow poorly; at this time, it is necessary to remove these seedlings from the hole tray with soil, and then take the well-developed seedlings from other hole trays Supplement: Because the seedlings are fragile and vulnerable to damage, conventional industrial manipulators cannot complete this work, and special seedling holders are required. At present, the hole seedling holder is mainly realized by pneumatic means, using the clamping force of the air claws to complete; but the clamping force of the air claws is not enough, and the pneumatic method requires an air source, which increases the external equipment , which increases the cost and is more troublesome to control.

In industrial seedling raising and automatic grafting operations, it is often encountered that a few seedlings grow poorly; at this time, it is necessary to remove these seedlings from the hole tray with soil, and then take the well-developed seedlings from other hole trays Supplement; because the seedlings are fragile and vulnerable to damage, conventional industrial manipulators cannot complete this work, and special seedling holders are required

At present, the hole seedling holder is mainly realized by pneumatic means, using the clamping force of the air claws to complete; but the clamping force of the air claws is not enough, and the pneumatic method requires an air source, which increases the external equipment , which increases the cost and is troublesome to control

Although there are also grippers driven by motors; but the clamping range of this kind of gripper is fixed, and it cannot be fully used for existing trays of different sizes
