Description

Technical Field

[0001] The utility model relates to the technical field of leech breeding, in particular to an anti - escape device for leech breeding. Background Technique

[0002] Leeches, commonly known as bloodsuckers, grow and reproduce in inland fresh - water waters. Leech breeding is to utilize the physiological functions of wild leeches and other organisms that have been domesticated by humans, such as the wild leech organisms like Placobdella manillensis and Poecilobdella manillensis, through artificial feeding and breeding, so that they convert feed and other organisms into bio - energy to obtain biological products such as the bodies and medicinal materials of leeches.

[0003] When breeding leeches, it is usually necessary to place the leeches in a breeding cage and then place the breeding cage in fresh water for breeding. In order to prevent leeches from escaping from the breeding cage, the breeding cage is closed during leech breeding. During the process of leech breeding, it is necessary to put feed into the breeding cage. Therefore, every time feed is put in, the breeding cage needs to be opened and then closed, which takes a long time. At the same time, if the breeding cage is set to be unidirectional for feeding, it will be difficult to take out the bred leeches. Therefore, it needs to be improved. Content of the Utility Model

[0004] The purpose of the utility model is to make up for the deficiencies of the prior art and provide an anti - escape device for leech breeding.

[0005] To achieve the above - mentioned purpose, the utility model provides the following technical solution: An anti - escape device for leech breeding, including a first support ring, a second support ring and a protective net. The protective net is wrapped around the outer periphery of the first support ring and the second support ring, fixed to the first support ring and the second support ring, and its top is open. It further includes:

[0006] An anti - escape mechanism for facilitating feeding, which is arranged at the top of the protective net, used to prevent leeches from escaping and capable of putting feed into the inside of the protective net;

[0007] Among them, the anti - escape mechanism for facilitating feeding includes a support platform. The support platform is fixed at the open part of the top of the protective net. The top and bottom of the inner wall of the support platform are respectively fixed with a first fixing ring and a second fixing ring. The outer peripheries of the first fixing ring and the second fixing ring are both embedded with a first circular ring part. The top of the first fixing ring is sleeved with several groups of movable rods. The bottom of the movable rod passes through the first fixing ring and is fixed with a fixing plate. The outside of the fixing plate is fixed with a second circular ring part. One side of the fixing plate is connected with a baffle through a long strip. The top of the movable rod is fixed with a pull ring.

[0008] In the above, the two ends of the long strip respectively extend into the inside of the fixing plate and the baffle. A fillet is arranged between the fixing plate and the baffle. The long strip is made of elastic rubber.

[0009] As described above, the first circular ring member is made of iron, and the second circular ring member is made of a magnet. When the second circular ring member moves up and down, the first fixing ring and the second fixing ring can block the baffle plate.

[0010] As described above, the baffle plate is in an isosceles triangle shape. When the edges of two adjacent groups of baffle plates come into contact, they can close the opening at the top of the protective net.

[0011] As described above, when the movable rod moves to the lowest position, the baffle plate can contact the second fixing ring, and when the movable rod moves to the highest position, the baffle plate can contact the first fixing ring.

[0012] Compared with the prior art, this anti-escape device for leech farming has the following beneficial effects:

[0013] First, through the cooperation between the movable rod and the first fixing ring in the present utility model, the movable rod can move up and down along the inner side of the first fixing ring, so that the fixing plate can be driven by the movable rod to move up and down in the inner wall of the support platform. When the movable rod moves to the highest position, the fixing plate will contact the first fixing ring. At this time, the baffle plate will be blocked by the first fixing ring. Therefore, the baffle plate can only rotate downward. At this time, it will limit the escape of leeches from the open part at the top of the protective net. At the same time, the feed can be pressed downward against the baffle plate by using a hole or other objects, and the feed can be put into the inside of the protective net. Therefore, it can prevent the escape of leeches and facilitate the feeding of the feed.

[0014] Second, by driving the fixing plate to move downward by the movable rod in the present utility model, the baffle plate can be driven to contact the second fixing ring. At this time, the baffle plate will be blocked by the second fixing ring and can only move upward. By reversing the protective net and using the gravity of the leeches themselves to push the baffle plate to rotate and discharge from the open part of the protective net, it is convenient to take out the leeches.

[0015] Other advantages, objectives and features of the present utility model will be described to some extent in the subsequent description, and to some extent, they will be obvious to those skilled in the art based on the study of the following text, or can be taught from the practice of the present utility model.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-5 shown, the present utility model provides an anti-escape device for leech breeding, including a first support ring 1, a second support ring 2 and a protective net 3. The protective net 3 is wrapped around the outer periphery of the first support ring 1 and the second support ring 2 and is fixed to the first support ring 1 and the second support ring 2, and its top is open. It further includes:

[0024] An anti-escape mechanism convenient for feeding, which is arranged at the top of the protective net 3 and is used to prevent leeches from escaping and can feed the inside of the protective net 3;

[0025] Among them, the anti-escape mechanism convenient for feeding includes a support platform 4. The support platform 4 is fixed at the open part of the top of the protective net 3. The top and bottom of the inner wall of the support platform 4 are respectively fixed with a first fixing ring 5 and a second fixing ring 6. The outer peripheries of the first fixing ring 5 and the second fixing ring 6 are both embedded with a first circular ring member 7. The top of the first fixing ring 5 is sleeved with several groups of movable rods 8. The bottom of the movable rod 8 passes through the first fixing ring 5 and is fixed with a fixing plate 9. The outside of the fixing plate 9 is fixed with a second circular ring member 12. One side of the fixing plate 9 is connected with a baffle 11 through a strip 10. The top of the movable rod 8 is fixed with a pull ring 13.

[0026] Through the cooperation between the movable rod 8 and the first fixing ring 5, the movable rod 8 can move up and down along the inner side of the first fixing ring 5, so that the movable rod 8 can drive the fixing plate 9 to move up and down in the inner wall of the support platform 4. When the movable rod 8 moves to the highest position, the fixing plate 9 will contact the first fixing ring 5. At this time, the baffle 11 will be blocked by the first fixing ring 5. Therefore, the baffle 11 can only rotate downward. At this time, it will limit the escape of leeches from the open part at the top of the protective net 3. At the same time, the feed can be pressed downward against the baffle 11 by using a leak or other items, and the feed can be put into the protective net 3. Therefore, it can prevent the escape of leeches and facilitate the feeding of the feed.

[0027] As Figure 3 shown, both ends of the strip 10 extend into the fixing plate 9 and the baffle 11 respectively. There is a fillet between the fixing plate 9 and the baffle 11. The strip 10 is made of elastic rubber.

[0028] Through the design of the strip 10 and the fillet provided between the fixing plate 9 and the baffle 11, the baffle 11 can rotate. At the same time, through the elasticity of the strip 10, the baffle 11 can be pulled to reset, so that the baffles 11 can be closed to seal the open part at the top of the protective net 3.

[0029] As Figure 2 、 3 shown, the first ring part 7 is made of iron, and the second ring part 12 is made of magnet. When the second ring part 12 moves up and down, the first fixing ring 5 and the second fixing ring 6 can block the baffle 11.

[0030] Through the design of the second ring part 12, when the second ring part 12 moves upward, it will adsorb the first ring part 7 located inside the first fixing ring 5. When the second ring part 12 moves downward, it will fix the first ring part 7 located inside the second fixing ring 6, so as to adjust the position of the baffle 11.

[0031] As Figure 4 、 5 shown, the baffle 11 is in an isosceles triangle shape. When the edges of two adjacent baffles 11 contact, the opening at the top of the protective net 3 can be closed.

[0032] Through the design of the baffle 11, when two adjacent baffles 11 contact, they can be closed, so that the open part at the top can be closed by the protective net 3, and further prevent the leeches from escaping.

[0033] As Figure 2 shown, when the movable rod 8 moves to the lowest position, the baffle 11 can contact the second fixing ring 6. When the movable rod 8 moves to the highest position, the baffle 11 can contact the first fixing ring 5.

[0034] Through the design of the baffle 11, when the baffle 11 contacts the second fixing ring 6, the baffle 11 can only rotate upward, so as to facilitate pouring out the leeches inside the protective net 3. When the baffle 11 contacts the first fixing ring 5, the baffle 11 can only rotate downward, which is convenient for feeding.

[0035] Working principle:

[0036] When feeding the leeches, since the baffle 11 is blocked by the first fixing ring 5 and can only rotate downward, the baffle 11 can be pushed by using a funnel or other tools. At this time, the feed can be directly put into the protective net 3. After the feed is put in, the elastic force of the strip 10 will pull the baffle 11 back to its original position, so as to prevent the leeches from escaping. When it is necessary to take out the leeches after cultivation, only need to press the pull ring 13 to drive the movable rod 8 and the fixing plate 9 to move downward until the baffle 11 is blocked by the second fixing ring 6. At this time, the baffle 11 can only rotate upward. By reversing the protective net 3, the gravity of the leeches is used to squeeze the baffle 11, so that the baffle 11 rotates to open the opening at the top of the protective net 3, which is convenient for taking out the leeches.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
