Automatic injection mechanism for loach spawning induction needle

Abstract

The invention discloses an automatic injection mechanism for a loach spawning induction needle. The automatic injection mechanism comprises a mechanism shell, a clamping and releasing mechanism, a movable injection groove mechanism and an injection mechanism. The mechanism shell is a shell in the shape of an inclined hexahedron, a loach inlet is formed in the front side of the mechanism shell, a loach outlet is formed in the rear side of the mechanism shell, and observation openings are formed in the two side faces of the mechanism shell. The clamping and releasing mechanism is installed on an upper panel of the mechanism shell, the injection mechanism is installed on a base of the mechanism shell, and the movable injection groove mechanism is matched with the mechanism shell, can move in the mechanism shell and is matched with the loach inlet through supporting of the injection mechanism. The mechanism is simple in structure, low in cost and convenient to use and carry. Meanwhile, the mechanism is ingenious in structure, only one air cylinder is used, complex equipment such as a plc, a photoelectric sensor and a control electric box is not needed, meanwhile, smooth injection of a target can be achieved, the cost is greatly reduced, and the size is reduced. Loaches can be clamped more stably, and an adjustable effect is also achieved.

Description

technical field [0001] The invention belongs to the technical field of mechanical automation design, and in particular relates to an automatic injection mechanism for loach injection oxytocin needles. Background technique [0002] Due to the delicious taste and high nutritional value of loach, it is deeply loved by people, so many loach farmers have appeared all over the country. In order for farmers to increase production, the injection of oxytocin needles is essential. However, the mucus on the loach's body surface makes it difficult to grasp, which increases the difficulty of injection. The injection of thousands of loach has become a huge project. In order to solve the problem, some methods have appeared. For example, put the loach's head into the cut leather tube to prevent the loach from slipping, and one person fixes the other person for injection. In addition, the loach was frozen to a dormant state with ice water, and placed on a towel for injection. The common p...

Problems solved by technology

[0003] The existing continuous automatic injection device for loach hormone injection (CN105963044A) discloses a continuous automatic injection device for loach hormone injection, but the clamping mechanism of the device directly uses a cylinder to push the loach, which may be damaged due to the pressure of the cylinder. Too large will cause damage to the loach, and it may also cause inaccurate positioning of the loach due to insufficient clamping force; the device uses PLC to control multiple cylinders to work sequentially, which increases the production cost; finally, the PLC controls the photoelectric sensor to sense the loach, which is beneficial to the user. The operation level has great requirements and increases the pressure of after-sales service
