Abstract
Description
Technical Field
[0001] This utility model relates to the field of probiotic cultivation in aquaculture, and in particular to a probiotic cultivation 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. When propagating lactic acid bacteria, aquaculture farmers generally use opaque plastic buckets instead of professional precision containers to reduce costs and increase efficiency. The culture medium for lactic acid bacteria is also mostly low-cost formulas instead of standard MRS medium.
[0003] Currently, some aquaculture farmers need to manually inject water using a water pipe and use a hand-held mixer to stir the bacteria when cultivating lactic acid bacteria in opaque plastic buckets. During this process, the mixing blades can easily damage the inner wall of the plastic bucket. Furthermore, when farmers cultivate on a large scale, they need to prepare multiple buckets of probiotics. At this time, the manual operation is labor-intensive, tiring, and prone to errors.
[0004] Therefore, it is necessary to provide a new probiotic culture device for aquaculture to solve the above-mentioned technical problems. Utility Model Content
[0005] The technical problem solved by this utility model is to provide a probiotic culture device for aquaculture that allows farmers to easily and efficiently expand lactic acid bacteria culture, while also having a lower equipment cost than professional precision containers.
[0006] To solve the above-mentioned technical problems, the present invention provides a probiotic culture device for aquaculture, comprising: a support structure, the support structure including a base, a positioning structure and a container structure installed on the top of the base, the positioning structure including a guide rail, the guide rail being located on the upper side of the base and fixedly connected to the base through a connecting frame, the guide rail having a plurality of evenly spaced positioning holes on its surface, a slider being slidably connected to the guide rail surface, a fixing member being fixedly connected to one side wall surface of the slider, and a set screw being threadedly connected to the surface of the fixing member;
[0007] A stirring structure is installed on the surface of the slider. The stirring structure includes a positioning rod, the bottom of which is fixedly connected to the top of the slider. A top plate is fixedly connected to the top of the positioning rod. A threaded rod is rotatably connected to the bottom of the top plate away from the positioning rod. A bottom plate is rotatably connected to the bottom of the threaded rod. The bottom plate is fixedly connected to the outer circumference of the positioning rod. A bevel gear one is fixedly connected to the bottom end of the threaded rod. The bevel gear one is located on the lower side of the bottom plate. A bevel gear two meshes with one side of the bevel gear one. A fixed shaft is fixedly connected to the surface of the bevel gear two. The fixed shaft is rotatably connected to the slider. A movable part is sleeved on the threaded rod. A stirrer is fixedly connected to the front wall surface of the movable part.
[0008] As a further embodiment of this utility model, the movable part is threadedly connected to the threaded rod and slidably connected to the positioning rod, and the bottom end of the set screw is inserted into the positioning hole on one side and the bottom end of the set screw is in transition fit with the positioning hole.
[0009] Through the above technical solution, when producing multiple barrels of lactic acid bacteria liquid for large-scale aquaculture, the device specifically provides a base to support each opaque plastic barrel. A guide rail is located at the rear. When the user needs to inject water into each barrel or stir the raw materials, the pump inlet can first be connected to an external water source through a pipe. Then, the slider can be slid until the impeller of the mixer is suspended above one side of the opaque plastic barrel. At this point, the slider is finely adjusted so that the set screw aligns with the positioning hole on one side. Then, the set screw is rotated so that its end is inserted into the hole to fix the slider position. Next, the universal water hose is twisted so that its outlet extends into the barrel. Finally, the pump is turned on, and the liquid can be stirred. Water is poured into the bucket, and then farmers can add a measured amount of culture medium and rotate the handle. The meshing of the large and small gears quickly rotates the fixed shaft, allowing kinetic energy to be transmitted to the threaded rod through the engagement of bevel gear one and bevel gear two. This, in turn, drives the moving parts and the mixer to move down until the impeller on the mixer is inserted into the appropriate position in the water. Finally, the mixer is started to stir the liquid in the bucket. This structural design eliminates the need for farmers to hold the mixer and water pipes, making it easier and more convenient. It also reduces the risk of damage to the inner wall of the bucket, making the design more reasonable. Furthermore, the overall cost of the structure is lower than that of professional precision equipment, making it easier to promote and use among farmers.
[0010] As a further embodiment of this utility model, a small gear is fixedly connected to one end of the fixed shaft away from the second bevel gear, a large gear meshes with one side of the small gear, a connecting shaft is fixedly connected to the surface of the large gear, the connecting shaft is rotatably connected to the slider, and a rocker arm is fixedly connected to one end of the connecting shaft.
[0011] By adding small and large gears, the fixed shaft can rotate faster when the user turns the crank handle, which in turn makes the threaded rod rotate faster, so as to quickly adjust the height of the mixer.
[0012] As a further embodiment of this utility model, a pump body is fixedly connected to one edge of the top of the base, a hose is fixedly connected to the output end of the pump body, a universal shaping water pipe is fixedly connected to the end of the hose, and the universal shaping water pipe is fixedly connected to the top of the slider.
[0013] Through the above technical solution, the universal water pipe can be twisted and adjusted at will, making it convenient for users to insert its end into the desired opaque plastic bucket.
[0014] As a further embodiment of this utility model, the container structure includes a plurality of opaque plastic buckets evenly distributed laterally. Each of the opaque plastic buckets is located above a base and a triangular bracket is fixedly connected to the bottom of the opaque plastic bucket. The triangular bracket abuts against the top of the base and a limit ring is fixedly connected to the base surface located outside the triangular bracket. An opaque sealing cap is threadedly connected to the top of each opaque plastic bucket.
[0015] The above technical solution, by setting a limiting ring, can restrict the position of the opaque plastic bucket.
[0016] As a further embodiment of this utility model, a control module is fixedly connected to the top surface of the base located on one side of the pump body, and both the mixer and the pump body are electrically connected to the control module.
[0017] The above technical solution, through the setting of a control module, enables users to conveniently control the electrical components in the structure, thereby better completing the lactic acid bacteria propagation work.
[0018] Compared with related technologies, the probiotic culture device for aquaculture provided by this utility model has the following beneficial effects:
[0019] When preparing multiple barrels of lactic acid bacteria solution for large-scale aquaculture, this device provides a base to support each opaque plastic barrel. A guide rail is located at the rear. When the user needs to inject water into each barrel or stir the raw materials, first connect the pump inlet to an external water source via a pipe. Then, slide the slider until the mixer blades are suspended above one of the opaque plastic barrels. At this point, finely adjust the slider so that the set screw aligns with the positioning hole on one side. Then, rotate the set screw so that its end inserts into the hole to fix the slider position. Next, twist the universal water hose so that its outlet extends into the barrel. Finally, turn on the pump to inject the solution into the barrel. After adding water, farmers can add a measured amount of culture medium to the bucket and rotate the handle. The meshing of the large and small gears quickly rotates the fixed shaft, allowing kinetic energy to be transmitted to the threaded rod through the engagement of bevel gear one and bevel gear two. This, in turn, drives the moving parts and the mixer to move down until the impeller on the mixer is inserted into the appropriate position in the water. Finally, the mixer is started to stir the liquid in the bucket. This structural design eliminates the need for farmers to hold the mixer and water pipes, making it easier and more convenient. It also reduces the risk of damage to the inner wall of the bucket, making the design more reasonable. Furthermore, the overall cost of the structure is lower than that of professional precision equipment, making it easier to promote and use among farmers. Attached Figure Description

[0027] Please combine Figures 1 to 4 ,in, Figure 1 This is a schematic diagram of the overall structure of a probiotic culture device for aquaculture according to this utility model. Figure 1 ; Figure 2 This is a schematic diagram of the overall structure of a probiotic culture device for aquaculture according to this utility model. Figure 2 ; Figure 3 This is a partial structural diagram of a probiotic culture device for aquaculture according to the present invention. Figure 1 ; Figure 4 This is a partial structural diagram of a probiotic culture device for aquaculture according to the present invention. Figure 2 A probiotic culture device for aquaculture includes:
[0028] Support structure 1 includes a base 12, a positioning structure 2 and a container structure 4 are installed on the top of the base 12, the positioning structure 2 includes a guide rail 7, the guide rail 7 is located on the upper side of the base 12 and is fixedly connected to the base 12 through a connecting frame, the surface of the guide rail 7 is provided with a number of equally spaced and evenly distributed positioning holes 8, the surface of the guide rail 7 is slidably connected with a slider 13, a fixing member 22 is fixedly connected to one side wall surface of the slider 13, and a set screw 21 is threadedly connected to the surface of the fixing member 22;
[0029] A stirring structure 3 is installed on the surface of the slider 13. The stirring structure 3 includes a positioning rod 15. The bottom of the positioning rod 15 is fixedly connected to the top of the slider 13. A top plate is fixedly connected to the top of the positioning rod 15. A threaded rod 16 is rotatably connected to the bottom of the top plate away from the positioning rod 15. A bottom plate is rotatably connected to the bottom of the threaded rod 16. The bottom plate is fixedly connected to the outer circumference of the positioning rod 15. A bevel gear 23 is fixedly connected to the bottom end of the threaded rod 16. The bevel gear 23 is located on the lower side of the bottom plate. A bevel gear 24 meshes with one side of the bevel gear 23. A fixed shaft is fixedly connected to the surface of the bevel gear 24. The fixed shaft is rotatably connected to the slider 13. A movable part 17 is sleeved on the threaded rod 16. A mixer 18 is fixedly connected to the front wall surface of the movable part 17.
[0030] like Figure 1-4As shown, the movable part 17 is threadedly connected to the threaded rod 16 and slidably connected to the positioning rod 15. The bottom end of the set screw 21 is inserted into the positioning hole 8 on one side and the bottom end of the set screw 21 is in transition fit with the positioning hole 8.
[0031] When preparing multiple barrels of lactic acid bacteria solution for large-scale aquaculture, the device provides a base 12 to support each opaque plastic barrel 5. A guide rail 7 is located at the rear of the base. When the user needs to inject water into each barrel or stir the raw materials, the pump body 10 input end can be connected to an external water source through a pipe. Then, the slider 13 can be slid until the impeller of the mixer 18 is suspended above one side of the opaque plastic barrel 5. At this point, the slider 13 is slightly adjusted so that the set screw 21 aligns with the positioning hole 8 on one side. Then, the set screw 21 is rotated so that its end is inserted into the hole to fix the position of the slider 13. Next, the universal water pipe 14 is twisted so that its outlet extends into the barrel. Then, the pump body 10 is turned on to inject water into the barrel. After filling the tank with water, farmers can add a measured amount of culture medium and rotate the handle. The meshing of the large gear 20 and the small gear 19 rapidly rotates the fixed shaft, allowing kinetic energy to be transmitted to the threaded rod 16 through the engagement of the first bevel gear 23 and the second bevel gear 24. This, in turn, drives the moving part 17 and the mixer 18 to move downwards until the blades on the mixer 18 are inserted into the appropriate position in the water. Finally, the mixer 18 is started to stir the liquid in the tank. This structural design eliminates the need for farmers to hold the mixer 18 and water pipes, making operation easier and more convenient. It also reduces the risk of damage to the inner wall of the tank, making the design more reasonable. Furthermore, the overall cost of the structure is lower than that of professional precision equipment, making it easier to promote and use among farmers.
[0032] like Figure 1-4 As shown, a small gear 19 is fixedly connected to the end of the fixed shaft away from the bevel gear 24. A large gear 20 meshes with one side of the small gear 19. A connecting shaft is fixedly connected to the surface of the large gear 20. The connecting shaft is rotatably connected to the slider 13, and a rocker arm is fixedly connected to one end of the connecting shaft.
[0033] By adding a small gear 19 and a large gear 20, the fixed shaft can rotate faster when the user turns the crank handle, which in turn allows the threaded rod 16 to rotate faster, so as to quickly adjust the height of the mixer 18.
[0034] like Figure 1-4 As shown, a pump body 10 is fixedly connected to one edge of the top of the base 12. A hose is fixedly connected to the output end of the pump body 10. A universal shaping water pipe 14 is fixedly connected to the end of the hose. The universal shaping water pipe 14 is fixedly connected to the top of the slider 13.
[0035] The universal water hose 14 can be twisted and adjusted at will, making it convenient for users to insert its end into the desired opaque plastic bucket 5.
[0036] like Figure 1-4As shown, the container structure 4 includes several opaque plastic buckets 5 evenly distributed laterally. The opaque plastic buckets 5 are all located above the base 12 and the bottom of the opaque plastic buckets 5 is fixedly connected to a triangular bracket. The triangular bracket abuts against the top of the base 12 and a limit ring 6 is fixedly connected to the surface of the base 12 located outside the triangular bracket. The top of the opaque plastic buckets 5 is threadedly connected to an opaque sealing cap 9.
[0037] By setting a limiting ring 6, the position of the opaque plastic bucket 5 can be restricted.
[0038] like Figure 1-4 As shown, a control module 11 is fixedly connected to the top surface of the base 12 located on one side of the pump body 10. The mixer 18 and the pump body 10 are both electrically connected to the control module 11.
[0039] By setting up control module 11, users can easily control the electrical components in the structure, thereby better completing the lactic acid bacteria propagation work.
[0040] The working principle of the probiotic culture device for aquaculture provided by this utility model is as follows:
[0041] When preparing multiple barrels of lactic acid bacteria solution for large-scale aquaculture, the device provides a base 12 to support each opaque plastic barrel 5. A guide rail 7 is located at the rear of the base. When the user needs to inject water into each barrel or stir the raw materials, the pump body 10 input end can be connected to an external water source through a pipe. Then, the slider 13 can be slid until the impeller of the mixer 18 is suspended above one side of the opaque plastic barrel 5. At this point, the slider 13 is slightly adjusted so that the set screw 21 aligns with the positioning hole 8 on one side. Then, the set screw 21 is rotated so that its end is inserted into the hole to fix the position of the slider 13. Next, the universal water pipe 14 is twisted so that its outlet extends into the barrel. Then, the pump body 10 is turned on to inject water into the barrel. After filling the tank with water, farmers can add a measured amount of culture medium and rotate the handle. The meshing of the large gear 20 and the small gear 19 rapidly rotates the fixed shaft, allowing kinetic energy to be transmitted to the threaded rod 16 through the engagement of the first bevel gear 23 and the second bevel gear 24. This, in turn, drives the moving part 17 and the mixer 18 to move downwards until the blades on the mixer 18 are inserted into the appropriate position in the water. Finally, the mixer 18 is started to stir the liquid in the tank. This structural design eliminates the need for farmers to hold the mixer 18 and water pipes, making operation easier and more convenient. It also reduces the risk of damage to the inner wall of the tank, making the design more reasonable. Furthermore, the overall cost of the structure is lower than that of professional precision equipment, making it easier to promote and use among farmers.
