Description

Technical Field

[0001] This invention belongs to the field of leech hatching and cultivation technology, and more specifically, it relates to a leech hatching and cultivation device and its breeding method. Background Technology

[0002] Leeches are organisms with important medicinal value, and their extracts have wide applications in the fields of medicine, health care, and beauty. With the advancement of global medical technology and the continuous exploration of the medicinal value of leeches, the demand for leeches has been increasing year by year. However, the supply of wild leeches is limited, so artificial breeding of leeches is gradually becoming a trend.

[0003] However, existing leech hatching and cultivation devices still have the following shortcomings in use: 1. Regarding humidity control, existing equipment cannot achieve uniform water replenishment to maintain stable humidity inside the incubator, which results in an unsatisfactory incubation environment and reduces the hatching rate; 2. The lack of effective guidance and collection mechanisms for collecting juvenile leeches makes the collection work difficult and inefficient; 3. Existing incubation equipment cannot simultaneously clean impurities on the incubation board when removing seedlings, which affects breeding efficiency and environmental hygiene.

[0004] This study investigates and improves existing structures and deficiencies, and provides a leech hatching and breeding device and its breeding method. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a leech hatching and breeding device and a breeding method thereof.

[0006] A leech hatching and cultivation device includes an incubation box, a water tank fixedly installed at the upper end of the incubation box, a temperature detector disposed between the incubation box and the water tank, the temperature detector being fixedly connected to the incubation box, dovetail grooves symmetrically formed at the upper end of the incubation box, sliding columns fixedly installed in the inner walls of each of the two dovetail grooves, sliding grooves symmetrically formed in the inner wall of the incubation box, and a scraper, a heating lamp, and a guide plate fixedly installed in the inner wall of the incubation box, the scraper being located between the heating lamp and the guide plate, and the guide plate being located below; The incubator is equipped with a sliding cultivation mechanism inside. The cultivation mechanism includes a baffle that is slidably installed in the incubation box, and a humidity detector is fixedly installed on the upper end of the baffle.

[0007] Preferably, a handle is fixedly installed on the side wall of the baffle, and an incubation plate is fixedly installed on the side wall of the baffle away from the handle. An inner groove is formed at the upper end of the incubation plate, and a first slot is formed in the inner wall of the inner groove.

[0008] Preferably, a water storage tank is slidably installed inside the inner tank, a second slot is provided in the inner wall of the water storage tank, and a locking block is fixedly installed on the side wall of the water storage tank, the locking block being installed in the first slot.

[0009] Preferably, a card strip is installed inside the second card slot, and climbing frames are symmetrically fixedly installed at the lower ends of the card strip. A collection net is fixedly installed at the lower ends of the two climbing frames, and the collection net is placed in the water storage tank.

[0010] Preferably, a U-shaped frame is fixedly installed on the side wall of the incubator, and a drive motor is fixedly installed on the side wall of the U-shaped frame.

[0011] Preferably, a rotating shaft is installed on the output end of the drive motor, and a drive bar is installed on the rotating shaft.

[0012] Preferably, symmetrically arranged slides are provided between the incubator and the water tank, and spraying components are fixedly installed at the lower ends of both slides. The spraying components are connected to the water tank through water pipes.

[0013] Preferably, dovetail blocks are symmetrically fixedly installed at the lower ends of the two slides, and the two dovetail blocks are slidably installed in the two dovetail grooves respectively. Springs are fixedly installed on the side walls of the two sets of dovetail blocks, and the two sets of dovetail blocks and springs are respectively sleeved on the two slide columns. The ends of the two sets of springs away from the two sets of dovetail blocks are fixedly connected to the inner wall of the dovetail groove.

[0014] A method for hatching and breeding leeches includes the following steps: S1: When cultivating and breeding, first clean the incubation equipment, then dry it in the sun, and put a layer of loose incubation soil 1-2 cm thick at the bottom for later use. S2: Remove the cocoons from the soil, collect them and sort them appropriately, distinguishing them by size, shape and color. Try to separate them for hatching according to size and maturity, and remove any broken cocoons. S3: Carefully lay the egg cocoon flat on the loose soil, and cover it with another 2 cm layer of loose soil. To maintain a certain level of humidity, place a moisturizing cotton cloth or clean aquatic plants on the loose soil. S4: To ensure the safe and rapid hatching of cocoons in the water, maintaining a certain level of humidity is essential. The air humidity in the hatching room should be maintained at around 70%–80%, and the humidity inside the hatching box should be maintained between 30% and 40%. During the hatching process, the dryness of the loose soil inside the hatching box should be frequently observed. If insufficient humidity is detected, the drive motor can be started. The drive motor will drive the rotating shaft to rotate, which in turn will drive the drive bar to rotate. At this time, the drive bar will contact the two slides and push the two slides to slide at both ends. The two slides will drive the two dovetail blocks to slide in the two dovetail grooves. At this time, the two sets of springs will be compressed. When the drive bar is misaligned with the two slides, the two sets of springs will drive the two slides to return to their original deformation. During this process, the spray assembly can be activated. The spray assembly will move with the slides to replenish water inside the hatching box. S5: The temperature inside the hatching room will directly affect the hatching time and hatching rate of leech egg cocoons. The temperature can be controlled by heating lamps. The hatching temperature should be controlled between 20 and 23°C. The hatching time of seedlings will be shortened to about 25 days before the leeches hatch. Too high or too low a temperature is not conducive to the hatching of egg cocoons. S6: When the leeches hatch, due to their attraction to water, the hatched leeches will crawl into the water tank and fall into the water. Then the leeches will climb up the climbing frame and rest on the rails. They are collected about once every half day. After all the eggs and cocoons have hatched, they can be transferred to the breeding pond for outdoor breeding.

[0015] The beneficial effects of this invention are as follows: In this invention, an incubation box, dovetail grooves, an incubation board, a drive motor, a rotating shaft, a drive bar, a slide, a spray assembly, and springs are provided. Under the action of the drive motor, the rotating shaft will rotate, and the rotating shaft will drive the drive bar to rotate. At this time, the drive bar will contact the two slides and push the two slides to slide at both ends. The two slides will drive the two dovetail blocks to slide in the two dovetail grooves. At this time, the two sets of springs will be compressed. When the drive bar is misaligned with the two slides, the two sets of springs will drive the two slides to restore their deformation and reset. During this process, the spray assembly can be activated. The spray assembly will move with the slides to replenish water inside the incubation box. This device can evenly spray water inside the entire incubation board, ensuring that the humidity inside the incubation box is fixed and improving the hatching and germination rate. In this invention, by providing a water storage tank, a retaining bar, and a climbing frame, when the leeches hatch, due to their water-attracting characteristics, the hatched leeches will crawl into the water storage tank and fall into the water. Then, the leeches will climb up the climbing frame onto the retaining bar to rest, making it easy for the device to collect the leeches. In this invention, an incubation box, a chute, a baffle, a handle, an incubation plate, and a water tank are provided. The handle will drive the baffle to slide out of the incubation box, and the first slot will also slide inside the chute. Then the baffle will drive the incubation plate and the water tank to slide outward, thereby collecting leeches in a concentrated manner. Moreover, the device is installed by snap-fit ​​placement, making it more convenient and labor-saving to install and disassemble. In this invention, by providing an incubation box, a scraper, a guide plate, and an incubation plate, the incubation plate will slide inside the incubation box when the seedlings are taken out. At this time, the scraper will come into contact with the incubation plate, and then the scraper will clean the impurities on the incubation plate. The cleaned impurities will fall onto the guide plate and then slide out of the incubation box, so that the device can clean impurities simultaneously during use, thereby improving the overall breeding efficiency.

A method for hatching and breeding leeches includes the following steps: S1: When cultivating and breeding, first clean the incubation equipment, then dry it in the sun, and put a layer of loose incubation soil 1-2 cm thick at the bottom for later use. S2: Remove the cocoons from the soil, collect them and sort them appropriately, distinguishing them by size, shape and color. Try to separate them for hatching according to size and maturity, and remove any broken cocoons. S3: Carefully lay the egg cocoon flat on the loose soil, and cover it with another 2 cm layer of loose soil. To maintain a certain level of humidity, place a moisturizing cotton cloth or clean aquatic plants on the loose soil. S4: To ensure the safe and rapid hatching of cocoons in water, maintaining a certain humidity level is essential. The humidity in the hatching room should be maintained at around 70%–80%, and the humidity inside the hatching box should be maintained between 30% and 40%. During the hatching process, the dryness of the loose soil inside the hatching box should be frequently observed. If insufficient humidity is detected, the drive motor 42 can be started. The drive motor 42 will drive the rotating shaft 43 to rotate, which in turn will drive the drive bar 44 to rotate. At this time, the drive bar 44 will contact the two slides 45 and push the two slides 45 to slide at both ends. The two slides 45 will drive the two dovetail blocks 47 to slide in the two dovetail grooves 14. At this time, the two sets of springs 48 will be compressed. When the drive bar 44 is misaligned with the two slides 45, the two sets of springs 48 will drive the two slides 45 to restore their deformation and reset. During this process, the spray assembly 46 can be started. The spray assembly 46 will move with the slides 45 to replenish water inside the hatching box 11. S5: The temperature inside the hatching room will directly affect the hatching time and hatching rate of leech egg cocoons. The temperature can be controlled by heating lamp tube 18. The hatching temperature should be controlled between 20 and 23℃. The hatching time of seedlings will be shortened to about 25 days before the leeches hatch. Too high or too low a temperature is not conducive to the hatching of egg cocoons. S6: When the leeches hatch, due to their attraction to water, the hatched leeches will crawl into the water tank 31 and fall into the water. Then the leeches will climb up the climbing frame 35 and onto the card bar 34 to rest. They are collected about once every half day. After all the egg cocoons have hatched, they can be transferred to the breeding pond for outdoor breeding.

[0020] Working principle: The first step is to detect the temperature and humidity inside the incubator 11 using temperature detector 13 and humidity detector 22. When water needs to be added, the drive motor 42 can be started. Under the action of the drive motor 42, the rotating shaft 43 will rotate, and the rotating shaft 43 will drive the drive bar 44 to rotate. At this time, the drive bar 44 will contact the two slides 45 and push the two slides 45 to slide at both ends. The two slides 45 will drive the two dovetail blocks 47 to slide in the two dovetail grooves 14. At this time, the two sets of springs 48 will be compressed. When the drive bar 44 is misaligned with the two slides 45, the two sets of springs 48 will drive the two slides 45 to restore their deformation and reset. During this process, the spray assembly 46 can be started. The spray assembly 46 will move with the slides 45 to add water to the inside of the incubator 11. This device can evenly spray water into the entire incubation plate 24, ensuring that the humidity inside the incubator 11 is fixed and improving the hatching rate. The second step is that when the leeches hatch, due to their attraction to water, the hatched leeches will crawl into the water tank 31 and fall into the water. Then the leeches will climb up the climbing frame 35 and onto the clip 34 to rest, making it easy for the equipment to collect the leeches. Third, when taking seedlings, the handle 23 can be pulled outward. At this time, the handle 23 will drive the baffle 21 to slide out of the incubation box 11. At this time, the first slot 26 will also slide inside the slot 16. Then the baffle 21 will drive the incubation plate 24 and the water storage tank 31 to slide outward, thereby collecting the leeches in a concentrated manner. The device is installed by snap-fit ​​placement, making the installation and disassembly of the equipment more convenient and labor-saving. In the fourth step, when the seedlings are taken out, the incubation plate 24 will slide inside the incubation box 11. At this time, the scraper 17 will come into contact with the incubation plate 24, and the scraper 17 will clean the impurities on the incubation plate 24. The cleaned impurities will fall onto the guide plate 19 and then slide out of the incubation box 11, so that the equipment can clean impurities at the same time during use, thus improving the overall breeding efficiency.
