Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a probiotic dispensing device for aquaculture. Background Technology

[0002] Aquaculture probiotics are microbial preparations used in aquaculture. They improve water quality, enhance the health of aquatic animals, and promote aquaculture efficiency through the action of beneficial microorganisms. Common types of probiotics in this field include Bacillus, lactic acid bacteria, yeast, photosynthetic bacteria, and nitrifying bacteria, etc.

[0003] Currently, when aquaculture farmers apply probiotics, they sometimes add lactic acid bacteria to the ponds to suppress algae and improve water quality. Sometimes they choose to apply the probiotics along the pond edge in the evening, because water spiders tend to be more active on the water surface near the pond edge at this time. Lactic acid bacteria decompose organic waste and stabilize the pH value, which promotes their reproduction. At the same time, after water spiders ingest organic debris or algae containing lactic acid bacteria, they carry lactic acid bacteria in their bodies. When water spiders are ingested by fish fry, it can improve their intestinal health.

[0004] During this process, farmers often need to drag plastic buckets containing lactic acid bacteria along the edge of the pond and spray them with handheld sprayers, which is quite inconvenient. For some bacteria, farmers need to mount the equipment on a small boat to achieve even spraying in all areas of the pond. Traditional probiotic dispensing devices are not convenient for use in multiple situations and cannot make it easier for farmers to spray lactic acid bacteria. The design is not user-friendly.

[0005] Therefore, it is necessary to provide a new probiotic delivery device for aquaculture to solve the above-mentioned technical problems. Utility Model Content

[0006] The technical problem solved by this utility model is to provide a probiotic dispensing device for aquaculture that allows farmers to easily and efficiently apply lactic acid bacteria along the pond edge, and is also convenient to mount on a boat for use.

[0007] To solve the above-mentioned technical problems, this utility model provides a probiotic dispensing device for aquaculture, comprising: a base, a container structure, a spraying structure, and an adjustment structure. The container structure, spraying structure, and adjustment structure are all installed on the surface of the base. Through slots are provided at the four corners of the base. The adjustment structure includes rotating parts. Four rotating parts are provided and are rotatably connected to the inner walls of the through slots at the four corners of the base. A first ear plate is fixedly connected to one side wall surface of the rotating parts. A caster wheel is fixedly connected to the bottom of the first ear plate. A second ear plate is fixedly connected to the top of the first ear plate. A countersunk hole is provided on the bottom surface of the rotating parts. A through hole is provided on the surface of the second ear plate.

[0008] Two connecting pieces distributed left and right are fixedly connected to the top surface of the base near the through groove. Limiting holes are opened on the surface of the two connecting pieces. A movable column is slidably connected between the interior of the two limiting holes. A spring is sleeved on the surface of the movable column located between the two connecting pieces. One end of the spring is fixedly connected to the connecting piece near the through groove, and the other end of the spring is fixedly connected to a toggle plate. The toggle plate is fixedly connected to the outer circumference of the movable column. The end of the movable column facing the through groove matches both the countersunk hole and the through hole. A limiting block is fixedly connected to the end of the movable column away from the through groove.

[0009] As a further embodiment of this utility model, the container structure includes a support frame, the bottom of which is fixedly connected to the top of the base, a plastic bucket is fixedly connected inside the support frame, a sealing cap is threadedly connected to the top of the plastic bucket, a fixing tube is fixedly connected to the surface of the sealing cap, the fixing tube communicates with the inside of the plastic bucket, and a sealing cap is threadedly connected to the top of the fixing tube.

[0010] Through the above technical solution, in this device, the container is fixed to the top of the base by a bracket. The container is used to hold probiotics such as lactic acid bacteria liquid to be sprayed. When the user wants to spray along the pond edge in the evening to promote the reproduction of water spiders, they can rotate the rotating parts on the four corners of the base in sequence and slide the actuating plate on that side to make the universal wheel at the bottom of the ear plate one contact the ground. The ear plate two can extend through the through groove to the side of the movable column. At this time, the actuating plate is released, and the movable column pops out under the reaction force of the spring and then inserts into the through hole to fix the angle of the rotating parts. In this way, the staff can push the whole device along the pond edge without manually dragging the plastic bucket to splash, making the operation more convenient and easy. When the user needs to drive the boat to evenly spray probiotics on the water surface, the rotating parts can be rotated in the opposite direction, and the movable column can be inserted into the sinkhole at its bottom to flip the universal wheel over, so that the bottom of the base can be stably placed on the hull of the boat. The structural design is reasonable and convenient for users to quickly adjust according to the usage scenario.

[0011] As a further embodiment of this utility model, the spraying structure includes a vertical support, which is fixedly connected to one side edge of the top of the base. An installation component is fixedly connected to the top of the vertical support, and a pump body is fixedly connected to the side wall surface of the vertical support facing the plastic bucket. An inlet hose is fixedly connected to the input end of the pump body.

[0012] With the above technical solution, users can connect the pump body to an external power source, then unscrew the sealing cap on the top of the opaque plastic bucket, and insert one end of the liquid inlet hose into the inside of the plastic bucket along the fixed tube, thereby facilitating the pump body to extract the probiotics inside.

[0013] As a further embodiment of this utility model, a rotating sleeve is rotatably connected to the top edge of the mounting component on the side away from the pump body. A spray pipe is fixedly connected to the inner wall of the rotating sleeve. A sliding sleeve is fitted on the surface of the spray pipe near the pump body. A rotating arm is rotatably connected to the bottom of the sliding sleeve. A vertical shaft is fixedly connected to the end of the rotating arm away from the sliding sleeve. The vertical shaft is rotatably connected to the mounting component. A connecting hose is fixedly connected to the end of the spray pipe facing the plastic bucket. The other end of the connecting hose is fixedly connected to the output end of the pump body. A nozzle is fixedly connected to the end of the spray pipe away from the plastic bucket.

[0014] With the above technical solution, when the farmer sprays along the pond edge, the pin on the crank handle is inserted into the positioning hole to limit the position of the crank handle. At this time, the angle of the spray pipe is fixed. The farmer can move the whole device by pushing the handle fixed on the base. Then, the pump body is turned on, and the probiotics in the plastic bucket are drawn into the nozzle at the end of the spray pipe through the liquid inlet hose. The bacterial liquid can then be sprayed onto one side of the pond surface. When spraying evenly on the boat, the operator at the rear starts the boat, while the operator at the front can pull out the pin and rotate the crank handle. The rotational kinetic energy is transmitted to the rotating arm through the cooperation of bevel gear one and bevel gear two. Since the sliding sleeve at the end of the rotating arm is fitted on the spray pipe and the spray pipe is rotatably connected to the top of the mounting part through the rotating sleeve, the spray pipe will swing back and forth when the rotating arm rotates. This allows the bacterial liquid sprayed from the nozzle at the end to be sprayed more evenly. The operator does not need to hold the spray pipe back and forth for the whole process, which is more labor-saving and convenient. The structural design is user-friendly.

[0015] As a further embodiment of this utility model, a bevel gear one is fixedly connected to the bottom of the vertical shaft, a bevel gear two is meshed on one side of the bevel gear one, a horizontal shaft is fixedly connected to the surface of the bevel gear two, and the horizontal shaft is rotatably connected to the bottom of the mounting component.

[0016] Through the above technical solution, by utilizing the cooperation of bevel gear one and bevel gear two, the rotational kinetic energy generated by the operator rotating the crank handle will be transmitted to the rotating arm on one side, thereby driving the spray pipe to swing.

[0017] As a further embodiment of this utility model, a rocker arm is fixedly connected to the end of the horizontal shaft away from the second bevel gear. A circular hole is provided on the surface of the rocker arm, and a pin is inserted through the circular hole with a transition fit between the pin and the circular hole. A positioning hole matching the pin is provided on the front wall surface of the mounting component, and one end of the pin extends into the positioning hole.

[0018] By inserting the pin into the round hole and the positioning hole, the crank handle can be limited.

[0019] Compared with related technologies, the probiotic dispensing device for aquaculture provided by this utility model has the following beneficial effects:

[0020] 1. In this utility model, the container is fixed to the top of the base by a bracket. The container is used to hold probiotics such as lactic acid bacteria liquid to be sprayed. When the user wants to spray along the pond edge in the evening to promote the reproduction of water spiders, he can rotate the rotating parts on the four corners of the base in sequence and slide the actuating plate on the side to make the universal wheel at the bottom of the ear plate one contact the ground, while the ear plate two can extend through the through groove to the side of the movable column. At this time, the actuating plate is released, and the movable column pops out under the reaction force of the spring and then inserts into the through hole to fix the angle of the rotating parts. In this way, the staff can push the whole device along the pond edge without manually dragging the plastic bucket to splash, making the operation more convenient and easy. When the user needs to drive the boat to evenly spray probiotics on the water surface, the rotating parts can be rotated in the opposite direction and the movable column can be inserted into the sinkhole at the bottom to flip the universal wheel over, so that the bottom of the base can be stably placed on the hull. The structure is reasonably designed and convenient for users to quickly adjust according to the usage scenario.

[0021] 2. In this utility model, when the farmer sprays the liquid along the pond edge, the pin on the crank handle is inserted into the positioning hole to limit the position of the crank handle. At this time, the angle of the spray pipe is fixed. The farmer can move the whole device by pushing the handle fixed on the base. Then, the pump body is turned on, and the probiotics in the plastic bucket are drawn into the nozzle at the end of the spray pipe through the liquid inlet hose. The bacterial liquid can then be sprayed onto one side of the pond surface. When the liquid is evenly sprayed on the boat, the operator at the rear starts the boat, while the operator at the front can pull out the pin and rotate the crank handle. The rotational kinetic energy is transmitted to the rotating arm through the cooperation of bevel gear one and bevel gear two. Since the sliding sleeve at the end of the rotating arm is fitted on the spray pipe and the spray pipe is rotatably connected to the top of the mounting part through the rotating sleeve, the spray pipe will swing back and forth when the rotating arm rotates, so that the bacterial liquid sprayed from the nozzle at its end can be sprayed more evenly.

[0029] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a probiotic dispensing device for aquaculture according to the present invention; Figure 2 This is a partial structural breakdown diagram of a probiotic dispensing device for aquaculture according to this utility model. Figure 1 ; Figure 3 This is a partial structural schematic diagram of a probiotic dispensing device for aquaculture according to the present invention; Figure 4 This is a partial structural breakdown diagram of a probiotic dispensing device for aquaculture according to this utility model. Figure 2 A probiotic dispensing device for aquaculture includes:

[0030] The base 1, container structure 2, spraying structure 3, and adjustment structure 4 are all installed on the surface of the base 1. The four corners of the base 1 are provided with through slots. The adjustment structure 4 includes a rotating component 10. There are four rotating components 10, which are rotatably connected to the inner walls of the through slots at the four corners of the base 1. A first ear plate is fixedly connected to one side wall surface of the rotating component 10. A universal wheel 13 is fixedly connected to the bottom of the first ear plate. A second ear plate is fixedly connected to the top of the first ear plate. A countersunk hole 11 is provided on the bottom surface of the rotating component 10. A through hole 12 is provided on the surface of the second ear plate.

[0031] Two connecting parts distributed on the left and right are fixedly connected to the top surface of the base 1 near the through groove. Limiting holes are opened on the surface of the two connecting parts. A movable column 8 is slidably connected between the two limiting holes. A spring 9 is sleeved on the surface of the movable column 8 located between the two connecting parts. One end of the spring 9 is fixedly connected to the connecting part near the through groove. The other end of the spring 9 is fixedly connected to a toggle plate. The toggle plate is fixedly connected to the outer circumference of the movable column 8. The end of the movable column 8 facing the through groove matches the countersunk hole 11 and the through hole 12. A limiting block is fixedly connected to the end of the movable column 8 away from the through groove.

[0032] like Figure 1-4 As shown, the container structure 2 includes a support 5, the bottom of the support 5 is fixedly connected to the top of the base 1, a plastic bucket 6 is fixedly connected inside the support 5, a sealing cap 7 is threadedly connected to the top of the plastic bucket 6, a fixing tube is fixedly connected to the surface of the sealing cap 7, the fixing tube communicates with the inside of the plastic bucket 6, and a sealing cap is threadedly connected to the top of the fixing tube.

[0033] In this device, the container is fixed to the top of the base 1 by the bracket 5. The container is used to hold probiotics such as lactic acid bacteria liquid to be sprayed. When the user wants to spray along the pond edge in the evening to promote the reproduction of water spiders, the rotating parts 10 on the four corners of the base 1 can be rotated in sequence and the actuating plate on that side can be slid sideways, so that the universal wheel 13 at the bottom of the ear plate 1 contacts the ground, and the ear plate 2 can extend through the through groove to the side of the movable column 8. At this time, the actuating plate is released, and the movable column 8 pops out under the reaction force of the spring 9 and then inserts into the through hole 12. The internal mechanism is used to fix the angle of the rotating part 10. This allows the staff to push the entire device along the edge of the pond without having to manually drag the plastic bucket 6 to spray the probiotics. This makes the operation more convenient and easier. When the user needs to evenly spray the probiotics on the water surface by boat, the rotating part 10 can be rotated in the opposite direction. The movable column 8 can be inserted into the sinkhole 11 at its bottom to flip the universal wheel 13 over, so that the bottom of the base 1 can be stably placed on the hull. The structure is reasonably designed and allows users to quickly adjust it according to the usage scenario.

[0034] like Figure 1-4 As shown, the spraying structure 3 includes a vertical support, which is fixedly connected to the top edge of the base 1. An installation part 14 is fixedly connected to the top of the vertical support. A pump body 19 is fixedly connected to the side wall surface of the vertical support facing the plastic bucket 6. An inlet hose 20 is fixedly connected to the input end of the pump body 19.

[0035] Users can connect the pump body 19 to an external power source, then unscrew the sealing cap on the top of the opaque plastic bucket 6, and insert one end of the liquid inlet hose 20 into the plastic bucket 6 along the fixed tube, so that the pump body 19 can easily extract the probiotics inside.

[0036] like Figure 1-4 As shown, a rotating sleeve 15 is rotatably connected to the edge of the surface of the top of the mounting component 14 away from the pump body 19. A spray pipe 16 is fixedly connected to the inner wall of the rotating sleeve 15. A sliding sleeve 18 is fitted on the surface of the spray pipe 16 near the pump body 19. A rotating arm 17 is rotatably connected to the bottom of the sliding sleeve 18. A vertical shaft is fixedly connected to the end of the rotating arm 17 away from the sliding sleeve 18. The vertical shaft is rotatably connected to the mounting component 14. A connecting hose is fixedly connected to the end of the spray pipe 16 facing the plastic bucket 6. The other end of the connecting hose is fixedly connected to the output end of the pump body 19. A nozzle is fixedly connected to the end of the spray pipe 16 away from the plastic bucket 6.

[0037] When the farmer sprays the liquid along the pond edge, the pin 24 on the crank handle 21 is inserted into the positioning hole 25 to limit the position of the crank handle 21. At this time, the angle of the spray pipe 16 is fixed. The farmer can move the entire device by pushing the handle fixed on the base 1. Then, the pump body 19 is turned on, and the probiotics in the plastic bucket 6 are drawn into the nozzle at the end of the spray pipe 16 using the liquid inlet hose 20. The bacterial liquid can then be sprayed onto one side of the pond surface. When the liquid is evenly sprayed on the boat, the operator at the rear starts the boat, while the operator at the front can pull out the pin 24 and turn the crank handle 25. The rotating handle 21 transmits rotational kinetic energy to the rotating arm 17 through the cooperation of bevel gear 1 22 and bevel gear 23. Since the sliding sleeve 18 at the end of the rotating arm 17 is fitted on the spray pipe 16 and the spray pipe 16 is rotatably connected to the top of the mounting part 14 by the rotating sleeve 15, the spray pipe 16 will swing back and forth when the rotating arm 17 rotates, so that the bacterial liquid sprayed from the nozzle at its end can be sprayed more evenly. The operator does not need to hold the spray pipe 16 back and forth for the whole process, which is more labor-saving and convenient, and the structural design is user-friendly.

[0038] like Figure 1-4 As shown, a bevel gear 22 is fixedly connected to the bottom of the vertical shaft, a bevel gear 23 meshes with one side of the bevel gear 22, a horizontal shaft is fixedly connected to the surface of the bevel gear 23, and the horizontal shaft is rotatably connected to the bottom of the mounting part 14.

[0039] By utilizing the cooperation of bevel gear 1 22 and bevel gear 23, the rotational kinetic energy generated by the operator rotating the crank handle 21 is transmitted to the rotating arm 17 on one side, thereby driving the spray pipe 16 to swing.

[0040] like Figure 1-4 As shown, a rocker arm 21 is fixedly connected to the end of the horizontal shaft away from the bevel gear 23. A round hole is opened on the surface of the rocker arm 21, and a pin 24 is inserted inside the round hole and the pin 24 is in transition fit with the round hole. A positioning hole 25 matching the pin 24 is opened on the front wall surface of the mounting part 14, and one end of the pin 24 extends into the positioning hole 25.

[0041] Inserting the pin 24 into the round hole and positioning hole 25 will limit the movement of the crank handle 21.

[0042] The working principle of the probiotic dispensing device for aquaculture provided by this utility model is as follows:

[0043] First step: In this device, the container is fixed to the top of the base 1 by the bracket 5. The container is used to hold probiotics such as lactic acid bacteria liquid to be sprayed. When the user wants to spray along the pond edge in the evening to promote the reproduction of water spiders, the rotating parts 10 on the four corners of the base 1 can be rotated in sequence and the actuating plate on that side can be slid sideways, so that the universal wheel 13 at the bottom of the ear plate 1 contacts the ground, while the ear plate 2 can extend through the through groove to the side of the movable column 8. At this time, the actuating plate is released, and the movable column 8 pops out under the reaction force of the spring 9 and then inserts into the through hole. Inside 12, the angle of the rotating part 10 is fixed, so that the staff can push the whole equipment along the edge of the pond without having to manually drag the plastic bucket 6 to splash, making the operation more convenient and easy. When the user needs to drive the boat to evenly splash probiotics on the water, the rotating part 10 can be rotated in the opposite direction, and the movable column 8 can be inserted into the sinkhole 11 at its bottom to flip the universal wheel 13 over, so that the bottom of the base 1 can be stably placed on the hull. The structure is reasonably designed and convenient for users to quickly adjust according to the usage scenario.

[0044] The second step: When the farmer sprays the solution along the pond edge, the pin 24 on the crank handle 21 is inserted into the positioning hole 25 to limit the position of the crank handle 21. At this time, the angle of the spray pipe 16 is fixed. The farmer can move the entire device by pushing the handle fixed on the base 1. Then, the pump body 19 is turned on, and the probiotics in the plastic bucket 6 are drawn into the nozzle at the end of the spray pipe 16 using the liquid inlet hose 20. The bacterial solution can then be sprayed onto one side of the pond surface. When the solution is evenly sprayed on the boat, the operator at the rear starts the boat, while the operator at the front can pull out the pin 24. The crank handle 21 is rotated, and the rotational kinetic energy is transmitted to the rotating arm 17 through the cooperation of bevel gear 1 22 and bevel gear 23. Since the sliding sleeve 18 at the end of the rotating arm 17 is fitted on the spray pipe 16 and the spray pipe 16 is rotatably connected to the top of the mounting part 14 by the rotating sleeve 15, the spray pipe 16 will swing back and forth when the rotating arm 17 rotates, so that the bacterial liquid sprayed from the nozzle at its end can be sprayed more evenly. The operator does not need to hold the spray pipe 16 back and forth for the whole process, which is more labor-saving and convenient, and the structural design is user-friendly.
