Description

Technical Field

[0001] This utility model relates to the field of leech farming, and in particular to a protective net for a leech farming device for Chinese medicinal materials. Background Technology

[0002] Leeches, as a traditional Chinese medicine, have shown significant medicinal value in treating injuries, hypertension, coronary heart disease, and tumors. In the artificial breeding of leeches, protective nets are a key facility to ensure the success of breeding, and their importance directly affects the yield and quality of the breeding. Therefore, protective nets are a key facility in the breeding system.

[0003] Traditional leech farming protective nets mostly use welded or bolted structures. During installation, external tools are needed to assemble them on-site at the bottom of the pond, and then a fabric net is hung to prevent birds and animals from entering.

[0004] Existing protective nets generally lack depth adjustment mechanisms, making it impossible to adjust the protective depth according to changes in riverbed geology and water level. Fixed structures cannot adapt to different pond topographical variations, and re-welding and installation are required after pond dredging or bottom modification, increasing aquaculture costs. Therefore, a protective net for a medicinal herb leech aquaculture device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a protective net for a leech farming device, which aims to improve the problem that the protection depth cannot be adjusted according to riverbed geology and water level changes in the existing technology.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a protective net for a medicinal herb leech farming device, comprising an outer frame, a wire mesh hinged to the inner side wall of the top of the outer frame, a threaded rod connected to the bottom of the outer frame, a sliding rod inserted into the inner wall of the insert rod, a pressure plate fixedly connected to the bottom of the sliding rod, a limit rod elastically connected to the outer side wall of the outer frame via a limit spring, a limit block fixedly connected to the front end of the limit rod, and a limit groove formed on the outer arc surface of the sliding rod.

[0007] As a further description of the above technical solution:

[0008] The inner walls on both sides of the top of the outer frame are rotatably connected to semi-circular disks.

[0009] As a further description of the above technical solution:

[0010] The outer wall of the slide rod is slidably connected to the inner wall of the outer frame.

[0011] As a further description of the above technical solution:

[0012] The inner wall of the pressure plate is slidably connected to the outer wall of the insertion rod.

[0013] As a further description of the above technical solution:

[0014] One end of the limiting spring is fixedly connected to the outer side wall of the outer frame, and the other end of the limiting spring is fixedly connected to the end ring of the limiting rod.

[0015] As a further description of the above technical solution:

[0016] The limiting rod is slidably connected to the inner wall of the outer side of the outer frame, and the limiting block is slidably connected to the inner wall of the outer side of the outer frame.

[0017] As a further description of the above technical solution:

[0018] The limiting block is engaged with the inner wall of the limiting groove.

[0019] As a further description of the above technical solution:

[0020] The lower surface of the top of the semi-circular disk is in contact with the top of the outer end of the wire mesh.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting an outer frame, insert rod, slide rod, limit block, limit rod, and pressure plate, and through the threaded connection between the insert rod and the outer frame and the sliding design of the slide rod, quick installation or disassembly can be achieved, which greatly improves the efficiency compared with the traditional welded protective net. The linkage between the pressure plate and the slide rod can adjust the height of the pressure plate according to the riverbed depth through the limit groove, thereby improving the stability of the protective net in different aquatic environments, avoiding the failure of protection due to changes in the riverbed, and significantly reducing the maintenance cost of aquaculture.

[0023] 2. In this utility model, by setting an outer frame, wire mesh, and semi-circular disc, and by using the hinged limiting structure between the semi-circular disc and the wire mesh, it can withstand the impact of external forces such as water birds pecking at food. At the same time, by rotating the semi-circular disc, the top space can be quickly opened, which improves the feed delivery efficiency and avoids the problem of leeches escaping caused by the traditional flip-up structure.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 This utility model provides an embodiment of a protective net for a leech farming device, comprising an outer frame 1 made of rigid material to provide bottom support for a wire mesh 2. The wire mesh 2 is hinged to the inner top wall of the outer frame 1, serving to block debris or larger foreign objects and prevent birds and animals from harming the leeches. A threaded rod 3 is threaded to the bottom of the outer frame 1, used for installing the protective net. The entire net is then inserted into the bottom of the pond, providing bottom protection for the leech farming net. During storage or transportation, the net can be secured by screws. The insert rod 3 is connected to the sliding rod 4, which can also slide out through the bottom of the insert rod 3, achieving the effect of quick disassembly and assembly. The inner wall of the insert rod 3 is connected to the sliding rod 4, which is used to slide the pressure plate 5 at the bottom of the insert rod 3. The bottom of the sliding rod 4 is fixedly connected to the pressure plate 5, which is used to lower the pressure plate 5 to contact the riverbed through the sliding rod 4, so that the insert rod 3 can be stably inserted into the bottom of the pond, increasing the stability of the outer frame 1. The outer wall of the sliding rod 4 is slidably connected to the inner wall of the outer frame 1, and the inner wall of the pressure plate 5 is slidably connected to the outer wall of the insert rod 3.

[0034] Reference Figures 3-5The outer wall of the outer frame 1 is elastically connected to a limiting rod 7 via a limiting spring 6. The limiting rod 7 extends the limiting block 8 to the outside of the outer frame 1, facilitating manual pulling of the limiting rod 7 to disengage the limiting block 8 from the limiting groove 9 and release the limiting position. The front end of the limiting rod 7 is fixedly connected to the limiting block 8, which engages with the limiting groove 9 to restrict the vertical movement of the slide rod 4, keeping the pressure plate 5 at a fixed height. The outer arc surface of the slide rod 4 has a limiting groove 9, which is provided in several sets for multiple engagement of the limiting block 8. The height of the transformer plate 5 is determined by the fact that one end of the limiting spring 6 is fixedly connected to the outer wall of the outer frame 1, and the other end of the limiting spring 6 is fixedly connected to the end ring of the limiting rod 7. Through the opposing pressing force between the limiting spring 6 and the outer frame 1, the limiting block 8 is always locked in the limiting groove 9 without being affected by external force. The limiting rod 7 is slidably connected to the inner wall of the outer side of the outer frame 1, and the limiting block 8 is slidably connected to the inner wall of the outer side of the outer frame 1. The limiting block 8 is locked in the inner wall of the limiting groove 9.

[0035] Reference Figures 5-6 The inner walls on both sides of the top of the outer frame 1 are rotatably connected to a semi-circular disc 10. The semi-circular disc 10 is used to fit the top of the wire mesh 2 and restrict the unfolding of the wire mesh 2. When a large amount of feed for breeding needs to be poured in or leeches need to be released, the semi-circular disc 10 can be rotated to detach from the top of the wire mesh 2 to release the restriction, and then the wire mesh 2 can be unfolded to open the top space of the leech breeding net bag. The lower surface of the top of the semi-circular disc 10 contacts the top of the outer end of the wire mesh 2.

[0036] Working principle: When installing the protective net, the insertion rod 3 is connected to the outer frame 1 by threads. Then, the top of the sliding rod 4 is inserted along the bottom of the insertion rod 3. The insertion rod 3 is then inserted downwards into the bottom of the pond, while the bottom of the outer frame 1 contacts the top of the aquaculture net. Then, the limiting rod 7 is manually pulled to move the limiting block 8 away from the limiting groove 9 to release the limit. Then, the sliding rod 4 is pressed down to move the pressure plate 5 down until the pressure plate 5 contacts the riverbed. Then, the limiting rod 7 is released and the limiting spring 6 causes the limiting block 8 to spring back into the corresponding limiting groove 9 and lock in place, thereby increasing the stability of the outer frame 1 by increasing the contact area.

[0037] When feeding or leeches is needed, rotate the semicircular disc 10 to detach it from the top of the wire mesh 2. After the limit is released, the wire mesh 2 can be easily unfolded, opening up the top space of the leech farming net, thus improving the feeding efficiency. Under normal farming conditions, the semicircular disc 10 is attached to the top of the wire mesh 2, and the friction of the hinge point restricts the unfolding of the wire mesh 2 to prevent birds and animals from entering.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
