Rail driving type pot seedling transplanting machine tail end executing device

Abstract

The invention discloses a rail driving type pot seedling transplanting machine tail end executing device, and aims at providing a tail end executing device with the advantages that the control is simple and convenient; the fault rate is low; the structure is simple; the tail end executing device can be used for whole row seedling taking and aims at a pot seedling transplanting machine. The rail driving type pot seedling transplanting machine tail end executing device consists of an air cylinder, an air cylinder installing frame, a main support disc, a rail plate, a seedling pushing rail block, a seedling pushing needle, a seedling pushing limiting ring, a seedling taking needle, a seedling pushing control rod, a seedling pushing control block, a control connecting rod and a driving connecting rod. The seedling clamping and seedling releasing actions are completed by the rail plate driven by the air cylinder; the seedling pushing action is simultaneously completed by the seedling pushing rail block and the seedling pushing control rod; the air cylinder push rod acts on the seedling pushing control rod and the rail plate to realize the clamping and taking of the pot seedlings.

Description

technical field [0001] The invention is an end effector of a track-driven pot seedling transplanting machine, which is mainly used for moving pot seedlings from a high-density seedling tray into a seedling guiding belt, a seedling guiding tube or a planter. Background technique [0002] As an important part of the transplanting machine, the end effector has a decisive influence on the success rate of seedling picking and the efficiency of seedling picking. The development of the structure is simple, the control is convenient, and the end effector that is easy to install in the whole row is of great significance for improving the efficiency of seedling picking and the working efficiency of the transplanting machine. extremely important. Current existing research: (CN104704966A) uses a stepping motor to drive the disc, and controls the seedling needle through a connecting rod mechanism to complete the clamping; (CN104704965A) uses a cylinder to directly install the seedling ne...

Problems solved by technology

Current existing research: (CN104704966A) uses a stepping motor to drive the disc, and controls the seedling needle through a connecting rod mechanism to complete the clamping; (CN104704965A) uses a cylinder to directly install the seedling needle part, using a connecting rod The mechanism completes the clamping action; (CN101569257A) uses a motor to drive the cylindrical cam, and the roller is installed on the seedling needle fixing ring to drive the pointer to complete the clamping; (CN106068843A) the cylinder is driven, and the support plate is designed with grooves and set There are rotating joints; (CN103875341A) the magnetic device can complete the push rod action through the power-on and power-off of the electromagnet, and the seedling needles are added with an indexing device and a rotating joint; It is used in the whole row of seedling picking environment and is limited by size. The stepper motor for power supply is small in size and limited in torque, so it often cannot provide enough power. The commonly used linkage mechanism cannot maintain a stable clip. In the actual field environment, the connecting rod mechanism is easily deformed by external force, and the failure rate is high. There is an urgent need for an end effector that works stably in the complex and changeable field environment.
