End executor of potted vegetable seedling supply mechanical hand

Abstract

The invention discloses an end executor of a potted vegetable seedling supply mechanical hand. The end executor comprises a step motor, a shaft coupling, a supporting plate, supporting rods, a lead screw, a spiral slide sleeve, a lifting block, connecting rods, guide rods, a guide plate, a seedling withdrawal plate and seedling shovels, wherein two ends of each of the four supporting rods are connected with the supporting plate and the guide plate respectively, and two ends of the lead screw are mounted in the center of each of the supporting plate and the guide plate through bearings and connected with an output shaft of the step motor through the shaft coupling; the seedling shovels are fixed on the guide rods, the four guide rods penetrate through the guide plate and form a moving pair together with the guide plate, one end of each of the four connecting rods is connected with the lifting block through a hinge, and the other end of each of the four connecting rods is connected with each of the four guide rods through a hinge; the seedling withdrawal plate is fixed below the guide plate. The four seedling shovels extend into a hole to basically form a wrapped-type structure, so that a loose seedling substrate or a cotyledon-stage potted seedling in the hole can be completely taken out; same-age cotyledon-stage potted seedlings are moved into holes through cooperation of the seedling shovels and the seedling withdrawal plate, so that the seedling supply is realized, the seedling-raising efficiency is improved, and a technical support is provided for automated transplantation of potted vegetable seedlings.

Description

technical field [0001] The invention relates to an end effector of a manipulator for pot seedling transplantation, in particular to an end effector of a manipulator for seedling replenishment of pot seedlings. Background technique [0002] Plug seedling raising technology is a modern seedling raising method that uses different specifications of plug trays as seedling containers and adopts mechanized precision seeding, which is suitable for large-scale, commercial and industrial production. However, due to factors such as the difference between the seeds and the substrate in each hole and the influence of the cultivation environment, it cannot be guaranteed that the seeds in all the holes can germinate. Currently, about 15% of the holes in the hole have no seedlings. Seedling filling is a modern agricultural industrialized hole. An important part of plate seedling cultivation. . In the fully self-mechanized transplanting, the automatic seedling picking mechanism takes o...
