Description

Technical Field

[0001] The utility model belongs to the technical field of sea cucumber seedling cultivation, and particularly relates to an attachment device for industrialized sea cucumber seedling cultivation. Background Art

[0002] When the planktonic larvae (big ear larvae) of industrialized sea cucumber seedling cultivation develop into barrel-shaped larvae, an attachment base is needed for seeding and the next stage of cultivation. When the big ear larvae develop into barrel-shaped larvae and continue to develop into five-tentacle larvae and then juvenile sea cucumbers, selecting a suitable attachment base is the key to improving the metamorphosis rate and survival rate of the larvae. The traditional attachment base and its usage method are generally that PVC corrugated plates are inserted into frames and laid flat on the bottom of the pond, or polyethylene mesh sheets are strung together and put into the pond. The method of inserting PVC corrugated plates into frames has the advantages of good seeding effect and large bait attachment amount. However, the disadvantages are that the distance between the corrugated plates in the frames is too dense, and residual bait and feces are extremely easy to accelerate corruption at the bottom of the pond and in the tight space of the PVC corrugated plates, generating toxic and harmful substances; moreover, after the PVC corrugated plates are inserted into frames and laid flat on the bottom of the pond, the feeding operation process is time-consuming and laborious. The water body utilized by dozens of PVC corrugated plates between two layers of corrugated plate frames laid flat on the bottom of the pond is only about half of the depth of the pond water, resulting in the upper half of the water body in the pond not being effectively utilized, and the lower half and the bottom space of the pond being too crowded, which is relatively unfavorable for the growth and development of sea cucumber seedlings. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an attachment device for industrialized sea cucumber seedling cultivation to solve the problems put forward in the above background art.

[0004] To achieve the above purpose, the utility model provides the following technical solutions:

[0005] An attachment device for industrialized sea cucumber seedling cultivation includes a frame assembly for circulating and moving across the seedling cultivation pond. A number of suspension assemblies for suspending and increasing the attachment area in layers are evenly installed on the frame assembly; the frame assembly includes two symmetrically arranged fixed frames. Installation grooves are symmetrically arranged at the bottom of the fixed frames. Pulleys are installed on the fixed frames. A circulating pull rope is installed between the pulleys. A number of limit blocks are evenly distributed on the circulating pull rope; the suspension assembly includes a number of corrugated plates, which are evenly distributed up and down. Connecting line ropes are arranged between the four corners of the corrugated plates. The top ends of the connecting line ropes converge together and are installed with hooks.

[0010] Furthermore: the connecting cord is made of polyethylene material.

[0011] Compared with the prior art, the beneficial effects are:

[0012] 1. The hanging attachment is conducive to water circulation, avoiding the shortcomings of direct contact between the corrugated plate and the bottom of the pond and the deterioration of the bottom and water quality caused by the small spacing between the corrugated plates, thereby improving the attachment rate and survival rate of young ginseng;

[0013] 2. The hanging layer setting increases the attachment area and improves the space utilization;

[0014] 3. The setting of circulating movement across the nursery pond improves the convenience of retracting and releasing operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Please refer to Figures 1-4 , an attachment device for industrialized sea cucumber seedling cultivation, which includes a frame assembly for circulating and moving across the seedling cultivation pond, and a number of suspension assemblies for suspending and increasing the attachment area in layers are evenly installed on the frame assembly.

[0022] In this embodiment: The frame assembly includes two symmetrically arranged fixing frames 101. The fixing frames 101 are made of 204 stainless steel material. Installation grooves 102 are symmetrically arranged at the bottom of the fixing frames 101. The installation grooves 102 are U-shaped. Pulleys 103 are installed on the fixing frames 101. The pulleys 103 are connected to the fixing frames 101 by bearings. A circulating pulling rope 104 is installed between the pulleys 103. A number of limiting blocks 105 are evenly distributed on the circulating pulling rope 104. The limiting blocks 105 are made of polypropylene material and are bolted to the circulating pulling rope 104. The two fixing frames 101 are respectively fixed at both ends of the seedling cultivation pond through the installation grooves 102, so that the circulating pulling rope 104 circulates and moves across the seedling cultivation pond under the support of the pulleys 103 on the fixing frames 101. The limiting blocks 105 are used to fix the distance between the suspension assemblies;

[0023] In this embodiment: The suspension assembly includes a number of corrugated plates 201. The corrugated plates 201 are made of PVC microporous plate material with a pore diameter of 80 meshes on the surface. The corrugated plates 201 are evenly distributed up and down. The distance between the corrugated plates 201 is 3-5 cm. Connecting ropes 202 are arranged between the four corners of the corrugated plates 201. The connecting ropes 202 are made of polyethylene material. The tops of the connecting ropes 202 converge together and a hook 203 is installed. The bottoms of the connecting ropes 202 also converge together and a sinker 204 is installed. The corrugated plates 201 connected in series by the connecting ropes 202 are suspended under the limiting blocks 105 through the hooks 203, and the circulating pulling rope 104 is pulled to move, so that the corrugated plates 201 move into the seedling cultivation pond. At the same time, the sinker 204 pulls the upper and lower corrugated plates 201 to be spaced apart in layers through the connecting ropes 202, increasing the attachment area of sea cucumbers.

[0024] Working principle: First, the two fixing frames 101 are respectively fixed at both ends of the seedling cultivation pond through the installation grooves 102, so that the circulating pulling rope 104 crosses the seedling cultivation pond under the support of the pulleys 103 on the fixing frames 101. Then, the corrugated plates 201 connected in series by the connecting ropes 202 are suspended under the limiting blocks 105 through the hooks 203, and the circulating pulling rope 104 is pulled to move, so that the corrugated plates 201 move into the seedling cultivation pond. At the same time, the sinker 204 pulls the upper and lower corrugated plates 201 to be spaced apart in layers through the connecting ropes 202, increasing the attachment area of sea cucumbers.
