Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, and in particular to a leech farming feeding platform. Background Technology

[0002] Leeches, also known as bloodsuckers, live and reproduce in inland freshwater areas. They are a traditional Chinese medicinal aquatic animal. Their dried products are used in traditional Chinese medicine after being soaked in water. They are used to treat stroke, high blood pressure, blood stasis, amenorrhea, and injuries from falls and blows. Due to their high medicinal value, they are now widely farmed artificially. During the farming process, leeches usually need to be fed with nutrients such as blood clots regularly.

[0003] An existing patent publication number CN221241307U describes a feeding device for leech farming, which includes a lifting support and a feeder. The feeder is securely mounted on the lifting support, which includes a base, a nut, a screw, and a slide. The nut is mounted on the top of the base, the screw is threaded onto the nut, and the slide is slidably connected to the base. The top of the slide is connected to the bottom of the screw via a bearing. The feeder includes a connecting rod, an adjusting bolt, a square feeding ring, and a metal mesh. The adjusting bolt is threaded onto both ends of the connecting rod, one end of which is hinged to the square feeding ring and securely connected to it via the adjusting bolt. The metal mesh is fixedly mounted on the bottom of the square feeding ring. However, this device only controls the immersion depth of the feeder through lifting motion and is not equipped with a stirring paddle, vibrator, or rotating parts. It cannot actively break up or disperse blood clots, and the metal mesh is prone to clogging. Blood clots may get stuck in the mesh after being added, and it is difficult to achieve uniform dispersion by leeches sucking on the feed alone, which can easily lead to localized feed accumulation. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A leech farming feeding platform includes a floating platform body. A support platform assembly is detachably installed in the middle of the floating platform body. The support platform assembly includes support legs and a support box. The outer wall of the support legs can be fixedly installed to the floating platform body. The support box is fixedly installed on the upper surface of the support legs. An anti-clogging feeding component for stirring blood clots is rotatably installed inside the support box. The anti-clogging feeding component includes a servo motor, a rotating shaft, a stirring sleeve, and a partition assembly. The servo motor is fixedly installed on the top of the support legs. One end of the rotating shaft is rotatably installed on the drive end of the servo motor, and the other end of the rotating shaft is fixedly installed with a drive gear. The rotating shaft has a driven gear fixedly installed at one end, and the driving gear drives the driven gear to mesh. The stirring sleeve is fixedly installed on the outside of the rotating shaft. Bearings are installed at both ends of the two rotating shafts. The bearings are fixedly installed on the outer wall of the support box. Several sets of wedges are fixedly installed around the outer surface of the stirring sleeve. The partition group is fixedly installed below the two rotating shafts. The partition group includes a support rod and a partition plate. The two ends of the support rod are fixedly installed on the inner wall of the support box. Several sets of support rods are installed on the outer wall of the support rod. A feeding box is fixedly installed below the anti-blocking feeding assembly.

[0006] As an improvement to the above technical solution, a hinge plate is welded and installed on the outer wall of the support box, and a tilting box is rotatably installed on the hinge plate. A rotating plate is welded and installed on the side wall of the tilting box, and the hinge plate and the rotating plate are rotatably installed.

[0007] As an improvement to the above technical solution, inclined plates are fixedly installed on both sides of the top inner wall of the support box.

[0008] As an improvement to the above technical solution, a support plate is fixedly installed on the upper surface of the support leg, the servo motor is fixedly installed on one side of the upper surface of the support plate, the bottom walls of both sides of the support box are bolted to the support plate, and a protective cover is fixedly installed on the top of the support plate. The protective cover is installed on top of the servo motor, the driving gear, and the driven gear.

[0009] As an improvement to the above technical solution, several sets of perforated plates are fixedly installed inside the feeding box.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a dual-shaft reverse stirring system with gear transmission to achieve reverse rotation of two sets of stirring sleeves, forming a convection cutting effect to thoroughly break up blood clots. This avoids the blind spot problem of traditional single-shaft stirring. The graded and refined design, with wedge blocks for initial crushing and baffles for secondary refinement, ensures uniform feed particle size, reducing feeding difficulties for leeches. The servo motor control supports speed and running time adjustment, allowing dynamic adjustment of feeding amount according to the leech growth stage, reducing the frequency of manual operation and labor intensity. It is especially suitable for large-scale farms, adapting to different water depths and wind and wave environments, avoiding the risk of capsizing. Components such as support legs and stirring sleeves can be quickly replaced, reducing maintenance costs and preventing feed from accumulating instantly, leading to dissolution and waste or water quality deterioration.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-6 This utility model provides a technical solution:

[0021] A leech farming feeding platform includes a float platform body 1. A support platform assembly 2 is detachably installed in the middle of the float platform body 1. The support platform assembly 2 includes support legs 21 and a support box 23. The outer wall of the support legs 21 can be fixedly installed to the float platform body 1. The support box 23 is fixedly installed on the upper surface of the support legs 21. An anti-clogging feeding assembly 3 for stirring blood clots is rotatably installed inside the support box 23. The anti-clogging feeding assembly 3 includes a servo motor 31, a rotating shaft 32, a stirring sleeve 33, and a partition group 34. The servo motor 31 is fixedly installed on the top of the support legs 21. One end of a set of rotating shafts 32 is rotatably installed on the drive end of the servo motor 31, and the other end of the rotating shafts 32 is fixedly installed with a drive gear 321. A driven gear 323 is fixedly installed at one end of the shaft 32. The driving gear 321 drives the driven gear 323 to mesh and connect. The stirring sleeve 33 is sleeved and fixedly installed on the outside of the rotating shaft 32. Bearings 322 are sleeved and installed at both ends of the two sets of rotating shafts 32. The bearings 322 are fixedly installed on the outer wall of the support box 23. Several sets of wedges 331 are fixedly installed around the outer surface of the stirring sleeve 33. The partition group 34 is fixedly installed below the two sets of rotating shafts 32. The partition group 34 includes a support rod 341 and a partition plate 342. The two ends of the support rod 341 are fixedly installed on the inner wall of the support box 23. Several sets of support rods 341 are sleeved and installed on the outer wall of the support rod 341. A feeding box 4 is fixedly installed below the anti-blocking feeding assembly 3.

[0022] In this embodiment, the float platform body 1 serves as the floating base of the entire device, using buoyancy to stably suspend the feeding platform on the water surface, adapting to leech farming ponds of varying depths. It is made of lightweight, high-strength materials, such as polyethylene foam or hollow plastic, ensuring sufficient buoyancy and corrosion resistance. The support legs 21 of the support platform assembly 2 connect the float platform body 1 to the support box 23, providing vertical support. The detachable bolt connection facilitates assembly and maintenance. The bottom of the support legs 21 is longer than the float platform body 1 to lower the center of gravity and enhance resistance to wind and waves. The support box 23 serves as the mounting carrier 3 for the anti-clogging feeding component; its hollow internal structure accommodates components such as motors and gears and provides waterproof protection. The servo motor 31 of the anti-clogging feeding component 3 provides the power source and achieves precise control of stirring and feeding through forward and reverse rotation control. The active gear 321 meshes with the driven gear 323 to achieve dual-axis reverse rotation, which enhances the stirring effect. The bearing 322 reduces rotational friction and extends the service life of the equipment. The wedges 331 are arranged in a spiral shape. When rotating, they cut and break up the blood clots to prevent clumping and clogging of the feeding port. The support rod 341 and the partition plate 342 of the separator group 34 form a central barrier to further refine the blood clot particles and guide the feed to be evenly distributed to both sides. The feeding box 4 collects the stirred blood clots and slowly releases the feed through the bottom opening to avoid waste or water pollution caused by excessive feeding at one time.

[0023] Workflow: Place the float platform 1 on the surface of the aquaculture pond, adjust the support legs 21 to keep the feeding platform level and stable, fix the connecting bolts between the support legs 21 and the float platform 1 to ensure the structure is firm, put the blood clot into the top opening of the support box 23, the feed falls into the partition group 34, start the servo motor 31, the active gear 321 drives the driven gear 323 to rotate in the opposite direction, driving the two sets of rotating shafts 32 to rotate synchronously, the wedge 331 of the stirring sleeve 33 cuts the blood clot, the partition 342 of the partition group 34 further divides the two sides to form a uniform feed flow, the refined feed falls into the feed box 4 through the gap of the partition group 34, and is slowly released into the water through the bottom opening.

[0024] Beneficial effects: The dual-shaft reverse mixing system uses gear transmission to achieve reverse rotation of two sets of mixing sleeves 33, creating a convection cutting effect that thoroughly breaks up blood clots, avoiding the blind spot problem of traditional single-shaft mixing. The graded and refined design, with wedge blocks 331 for initial crushing and baffles 342 for secondary refinement, ensures uniform feed particle size, reducing feeding difficulties for leeches. The servo motor 31 controls and supports speed and running time adjustment, allowing dynamic adjustment of feeding amount according to the growth stage of leeches, reducing the frequency of manual operation and labor intensity. It is especially suitable for large-scale farms, adapting to different water depths and wind and wave environments, avoiding the risk of capsizing. Components such as support legs 21 and mixing sleeves 33 can be quickly replaced, reducing maintenance costs and preventing feed from accumulating instantly, leading to dissolution and waste or water quality deterioration.

[0025] Specifically, a hinge plate 231 is welded and installed on the outer wall of the support box 23, and a tilting box 24 is rotatably installed on the hinge plate 231. A rotating plate 241 is welded and installed on the side wall of the tilting box 24. The hinge plate 231 and the rotating plate 241 are rotatably installed.

[0026] In this embodiment, the hinge plate 231 is welded to the outer wall of the support box 23, serving as a fixed rotating base for the feeding inclined box 24. The hinge structure enables the flexible rotation of the feeding inclined box 24. The reinforced rib welding process ensures a firm connection with the support box 23, allowing it to withstand the weight of the inclined box and feed without deformation. The feeding inclined box 24 has a sloping groove structure that is wider at the top and narrower at the bottom, with an inclination angle generally between 30° and 45°, facilitating the natural sliding of feed by gravity. It is made of stainless steel, the same material as the support box 23. The rotating plate 241 is welded to the side wall of the inclined box and is rotatably connected to the hinge plate 231 via a pin, forming a rotating axis. The aquaculture personnel can directly pour the blood clots into the feeding inclined box 24, and the feed slides along the inclined surface into the interior of the support box 23, avoiding manual operation inside the equipment and reducing the risk of being bitten by leeches. The closed inclined surface structure of the feeding inclined box 24 prevents feed from splashing to the outside of the support box 23 when poured in, keeping the water surface of the aquaculture pond clean.

[0027] Specifically, inclined plates 35 are fixedly installed on both sides of the top inner wall of the support box 23.

[0028] In this embodiment, the inclined plates 35 are fixedly installed on both sides of the inner top wall of the support box 23, symmetrically distributed, with an inclination angle typically designed to be 30°-45° to ensure smooth feed flow. The material is the same as that of the support box 23, stainless steel, with a smooth surface to reduce feed adhesion. The inclined surface of the inclined plates 35 guides the blood-red block poured into the support box 23 to the central area directly above the anti-blocking feeding component 3 to prevent feed from accumulating at the edge of the support box 23, ensuring that the mixing sleeve 33 is evenly cut and preventing local clumping.

[0029] Specifically, a support plate 211 is fixedly installed on the upper surface of the support leg 21, a servo motor 31 is fixedly installed on one side of the upper surface of the support plate 211, the bottom walls of both sides of the support box 23 are bolted to the support plate 211, and a protective cover 22 is fixedly installed on the top of the support plate 211. The protective cover 22 is installed on the top of the servo motor 31, the drive gear 321, and the driven gear 323.

[0030] In this embodiment, the support leg 21 serves as the basic load-bearing component of the equipment, fixed to the edge of the aquaculture pond or the ground to provide stable support. Its upper surface is flat and has pre-drilled mounting holes for fixing the support plate 211. The support plate 211 is horizontally fixed to the upper surface of the support leg 21, forming a middle-level mounting platform for the equipment. The servo motor 31 is fixed to the upper surface of one side of the support plate 211 by bolts. The bottom walls on both sides of the support box 23 are rigidly connected to the support plate 211 by bolts to form an integral structure made of stainless steel. The support plate 211 provides a horizontal and stable mounting base for the servo motor 31, ensuring that the coaxiality error between the motor shaft and the stirring sleeve 33 is ≤0.1mm, thus avoiding gear meshing deviation caused by motor vibration. The protective cover 22 covers the support plate 211, completely enclosing the servo motor 31, the driving gear 321, and the driven gear 323. It is fixed to the support plate 211 by bolts to form a closed protective space, completely sealing the servo motor 31, the driving gear 321, and the driven gear 323 to prevent feed, water vapor, or leeches from entering.

[0031] Specifically, several sets of perforated plates 41 are fixedly installed inside the feeding box 4.

[0032] In this embodiment, the feed falls from the support box 23 into the feeding box 4 through the partition group 34. The first perforated plate 41 intercepts large particles, and the remaining feed slides to the second perforated plate 41 for further screening. Uniform particles enter the breeding pond through the holes of the perforated plate 41, and the leeches feed evenly, ensuring that the leeches ingest uniform particles and avoiding indigestion caused by excessively large particles.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
