Embodiment Construction

[0019] The present invention will be further described below in conjunction with the examples, but the present invention is not limited to the following examples.

[0020] like figure 1 and 2 As shown, it is an overall structure diagram of a polyhedral robotic gripper for marine life fishing, which is mainly composed of an input end 1, a first-type branch 2, and a second-type branch 3. The input end includes a motor 6, a lead screw 5, a coupling 4, a slide rail 7, a sun rod 8, and a base 9. The motor 6 rotates, and the lead screw 5 is driven to rotate through the coupling 4. The sun rod 8 is on the slide rail 7. Under the restraint and under the rotation of the lead screw 5, the translation in the vertical direction is realized; the branch chain A includes a hexagonal side plate 10, a quadrilateral side plate 11, a hexagonal bottom plate 12, and a first-class branch chain first-level connecting rod 13 , the first-type branched secondary connecting rod 14, the first-type bran...

Abstract

The invention discloses a polyhedral hand claw for marine life fishing, which belongs to the field of marine fishing equipment. Including the input end, the first type of branch chain, and the second type of branch chain, wherein the input end is through the cooperation of the motor, the lead screw and the slide rail to make the sun rod move up when the motor is rotating forward, and move down when the motor is reversed; the lead screw and The sun rod is threaded and has a self-locking function, which is used to enhance the sealing of the mechanism and protect the motor. The first-level connecting rods of the first type branch chain and the second type branch chain are connected with the sun rod, so that the sun rod drives the branch chain to move, the upward branch chain of the sun rod is opened, and the sun rod downward branch chain is closed; The connecting rod and side plate are designed as three four-bar linkages in series, so that the degree of freedom of the branch chain is 1, which is convenient for manipulation. Small holes are drilled on the side plate of the branch chain to facilitate drainage, reduce resistance and achieve lightweight design. The bottom plate of the branch chain is fixed with shovel claws to facilitate shoveling of submerged targets. There are reinforcing ribs on the side plate and the bottom plate to improve the strength. .

Description

technical field [0001] The invention belongs to a packaged marine creature grabbing robot, which belongs to the field of marine fishing equipment. Background technique [0002] With the rapid development of seafood aquaculture, the problem of fishing comes along with it. The farming method of seafood determines that most of the fishing methods are artificial. Due to the influence of seasons, pressure difference and oxygen supply method, the capture yield is low; it also causes harm to the body of the staff. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a package-type fishing mechanism that replaces manual fishing, which can replace the manual fishing method and reduce the work intensity. [0004] A polyhedral robotic gripper for marine life fishing, including an input end, a branch of the first type, a branch of the second type, and three parts. The input end includes a motor, a top plate, a slide rail, a sun rod, a lead screw, a co...
