Problems solved by technology

Doing so will cause stress to the prawns, especially during the mid-cycle harvesting process, or during the transfer of the larvae to the breeding pond, which will seriously affect the subsequent growth of the prawns
Shrimp can adapt to mild stress through self-regulation. When the stress is severe, the food intake of the shrimp decreases sharply or even does not eat, and some shrimp begin to swim in the pond; Reddening and other lesions; if not controlled, the shrimp tentacles and tail fans will turn red, and even the shrimp body will turn red, and the mixed infection of latent viruses and invading bacteria in the body will cause serious losses

Embodiment 1

[0023] Such as figure 1 As shown, a system for catching prawns includes a culture pond 7 with a greenhouse 1 installed above, a slide rail 8 is provided on the roof of the greenhouse 1, and a magnetic drive assembly 2 is correspondingly provided on the top of the slide rail 8, and the slide rail 8 is matched and connected. There are at least two pulleys 3, the bottom of the pulley 3 is connected with an electric control telescopic rod 4, and the bottom of the electric control telescopic rod 4 is connected with a fishing cage 6 through a rope body. In the present invention, a greenhouse 1 is set on the culture pond 7 and a slide rail 8 relative to the culture pond 7 is set on the roof of the greenhouse 1, and the slide rail 8 and the pulley 3 are used to cooperate with each other, and the magnetic drive assembly 2 drives the pulley 3 in The way of moving on the slide rail 8 drives the fishing cage 6 to move in the corresponding position of the breeding pond 7, and the electric ...

Embodiment 2

[0030] The pulley 3 includes a shell sleeved on the slide rail 8 and has a rolling wheel 301 inside, and a vibration-damping bar 302 is provided on the contact surface between the rolling wheel 301 and the slide rail 8 . The pulley with the above structure can ensure the firmness of the connection between the pulley 3 and the slide rail 8, and part of the shell of the pulley 3 is covered on the upper part of the slide rail 8 to facilitate the magnetic drive assembly 2 to generate an adsorption force on the pulley 3. The lower part of the shell of the pulley 3 It can be directly connected to the electronically controlled telescopic rod 4 without affecting the rolling of the scroll wheel 301. During the long-term contact process of the scroll wheel 301 with the slide rail 8, the surface of the scroll wheel 301 will inevitably be damaged by friction, and the surface of the scroll wheel 301 will continue to wear as time goes on. Enlargement will cause the vibration of the rolling w...

Embodiment 3

[0034] When the device of the present invention is actually used: the prawns are caught when the prawns are transferred to the culture pond or the prawns are grown, and the fishing cage is used to catch the prawns, and the magnetic drive assembly 2 is driven by the computer to drive the roller 3 to make the electric control telescopic rod 4 and the balance rod 5 Move to the side of the greenhouse, and the operator installs the fishing cage 6. After the installation is completed, the computer controls the magnetic drive assembly 2 to drive the roller 3 to slide on the slide rail 8 and slide to the designated position, and the computer controls the electronically controlled telescopic rod 4 to move downward. The retractable paddle fishing cage 6 is put into the breeding pond 7 to catch the prawns, and the slow-release particles 602 on the braided rope 601 can reduce the stress response of the prawns during the fishing process. The fishing cage 6 is lifted from the culture pond 7,...

Abstract

The invention discloses a shrimp catching system, which belongs to the technical field of shrimp culture. The shrimp catching system comprises a culture pond with a greenhouse arranged above; the topof the greenhouse is provided with a sliding rail; the upper part of the sliding rail is correspondingly provided with a magnetically-driven assembly; at least two pulleys are connected onto the sliding rail in a matched mode; the lower part of the pulley is connected with an electronically-controlled telescopic rod; and a catching cage is connected below the electronically-controlled telescopic rod through a rope body in a matched mode. Collection and release of the catching cage are controlled in a mechanical mode, the catching process is high in safety, the stress response of the shrimps isreduced, and human stress on the shrimps is avoided.

Description

technical field [0001] The invention belongs to the technical field of prawn cultivation, and in particular relates to a system for starting and catching prawns. Background technique [0002] Prawn (Penaeus orientalis), scientific name Oriental prawn, also known as Chinese prawn (Penaees chinensis, Chinese prawn), monodon prawn. Arthropoda, Mollusca, Decapod, Shrimpidae, Penaeus. Prawns are wide-temperature and wide-halt marine animals. The body of the prawn is long cylindrical, flat on the left and right sides, and the body is divided into head, thorax and abdomen, and consists of 20 body segments. The abdomen is long, muscular and well segmented. Prawn meat is delicious and has high economic value. The processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18-32 ° C. It also has a wide salt range. It is an excellent breeding species. Shrimp grows fast and has strong disease resistance. It has gradually become the main cultured shrimp...
