End effector of dry land potted tray seedling transplanter

Abstract

The invention relates to an end effector of a dry land potted tray seedling transplanter, which is characterized by comprising a stander (1) connected with a mechanical arm of the transplanter, wherein a motor (24) is arranged in the stander (1), an output shaft of the motor (24) is connected with a cylindrical cam (10), a driven link roller (12) of the cylindrical cam (10) is arranged on a pointer fixed ring (13), at least three pointers (14) are fixed on the pointer fixed ring (13), the lower end of the stander (1) is connected with pointer guiding pipes (19), each pointer (14) is arranged in each pointer guiding pipe (19) respectively, the length of the pointer (14) is longer than that of the pointer guiding pipe (19), and the lower end of the pointer guiding pipe (19) bends inwards. The end effector has a simple and compact integral structure, is convenient to mount and demount, has good independence, not only can be used in parallel to improve the working efficiency of picking seedlings but also can be controlled singly to increase the flexibility of picking the seedlings, and has light volume and low cost.

Description

technical field [0001] The invention relates to a seedling picking device, in particular to an automatic seedling picking mechanism applied to a dry land plug seedling transplanting machine. Background technique [0002] The end effector is an important part of the plug seedling transplanting machine. As a direct device for taking and putting seedlings, it is the key to distinguish between automatic transplanting and semi-automatic transplanting. The operation object of the end effector is the vegetable seedlings planted in the seedling tray, and it cannot complete the entire transplanting operation independently. Generally, the end effector needs to be connected to the transplanting robot arm, and the movement mode of the end effector is different depending on the robot arm. The single-job manipulator, the end effector moves with the manipulator arm to complete the transplanting. If the end effector is connected to large-scale parallel transplanting equipment, it usually ...

AI Technical Summary

Problems solved by technology

Although the efficiency of this kind of transplanting equipment is acceptable, based on the characteristics of pneumatic or hydraulic systems, it is only suitable for greenhouse operations. If it is placed outdoors in a field, it will be greatly affected by the environment, and its system stability cannot be guaranteed.

Moreover, the cost of pneumatic or hydraulic systems is high, bulky, difficult to control in the field, and poor in flexibility
