Problems solved by technology

[0004] The existing crab seed screening device for crab breeding has certain disadvantages in the process of use. The traditional crab seed screening device for crab breeding requires the user to perform the screening operation manually, thereby reducing the traditional usage. Due to the working efficiency of the crab seed screening device for crab breeding, it cannot use the lifting auxiliary structure to complete the screening operation of crab seedlings, and the function is single; secondly, the traditional crab seed screening device for crab breeding does not have multiple functions. The combined structure reduces the flexibility of the traditional crab seed screening device used for crab breeding; at the same time, the traditional crab seed screening device used for crab breeding does not have a water circulation structure and cannot recycle water, increasing The water consumption of the crab seed screening device used for crab breeding is reduced, which brings certain adverse effects to users

Abstract

The invention discloses a crab fry screening device for crab breeding. The crab fry screening device comprises a box body base and a lifting box hopper, the lifting box hopper is movably installed on the inner side of the upper end of the box body base, the inner side of the lower end of the lifting box hopper is movably sleeved with a splicing frame, a water storage tank is fixedly installed in the box body base and located below the lifting box hopper, two sets of hydraulic rods are fixedly installed on the portions, close to the two sides of the lifting box hopper, of the outer surface of the top end of the box body base, connecting clamping strips are movably installed on the outer surfaces of one ends of the hydraulic rods, and the lifting box hopper and the hydraulic rods are in butt joint through the connecting clamping strips. According to the crab fry screening device for crab breeding, the crab fry screening device is provided with a lifting type auxiliary structure, so that the screening operation efficiency of the crab fry screening device is effectively improved, meanwhile, the crab fry screening device can conduct water circulation operation, the water consumption of the crab fry screening device in use is reduced, and the crab fry screening device is convenient to use.

Description

technical field [0001] The invention belongs to the technical field of crab seed screening, in particular to a crab seed screening device for crab breeding. Background technique [0002] The crab's body is divided into cephalothorax and abdomen, and the back of the cephalothorax is covered with a carapace, and the shape varies from species to species. There are first and second pairs of antennae in the center of the forehead, and compound eyes with stalks on the outside. The mouthparts include 1 pair of mandibles, 2 pairs of small jaws and 3 pairs of maxillofadia. There are 5 pairs of thoracic feet on both sides of the carapace. The abdomen is degenerated, flat, and twists and turns on the ventral surface of the cephalothorax. The male abdomen is narrow and long, mostly triangular in shape, only the first two pairs of appendages are deformed into splices; the female abdomen is broad, with a pair of double-branched appendages on the 2nd to 5th segments, densely covered with ...
