Description

Technical Field

[0001] This invention relates to the field of aerator technology, specifically to a floating multi-layer deep-water aerator for agricultural aquaculture. Background Technology

[0002] An aerator is a machine commonly used in aquaculture. Its main function is to increase the oxygen content in the water to ensure that fish do not suffer from oxygen deficiency. It also inhibits the growth of anaerobic bacteria in the water, preventing water quality from deteriorating and threatening the fish's living environment. Aerators generally use their built-in air pumps to inject air into the water, thereby increasing the oxygen content.

[0003] A body of water is usually used to raise a variety of aquatic products. Different aquatic products live in different water layers and require different oxygen levels. Therefore, it is necessary to aerate the different water layers separately. Moreover, the water surface is often subject to wind and waves, which can cause local water level changes and block the air intake of the aerator, affecting the entry of air. Therefore, we have proposed a floating multi-layer deep-water aerator for agricultural aquaculture. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a floating multi-layer deep-water aerator for agricultural aquaculture, comprising:

[0005] A base plate made of high-density material, and support legs disposed on the sides of the base plate;

[0006] An oxygenation device, which has an aeration structure, is used to dissolve oxygen into the water body;

[0007] The oxygenation device includes:

[0008] The float is made of low-density material and is hollow. A telescopic tube is provided on the side of the float near the bottom plate.

[0009] The pump body has a pipe on the side near the bottom plate, and a layered oxygenation mechanism and a bottom oxygenation mechanism are also provided on the side of the pump body near the bottom plate.

[0010] The side of the float closest to the bottom plate is fixedly connected to the end of the telescopic tube furthest from the bottom plate. The end of the telescopic tube furthest from the float is fixedly connected to the side of the pump body furthest from the bottom plate. The side of the pump body closest to the bottom plate is fixedly connected to the side of the tube body furthest from the bottom plate. The inner side of the stratified aeration mechanism is fixedly connected to the outer surface of the tube body. The side of the bottom aeration mechanism furthest from the tube body is fixedly connected to the top of the bottom plate. The side of the bottom aeration mechanism furthest from the bottom plate is rotatably connected to the end of the tube body closest to the bottom plate. The aerator is placed inside the water body and fixed to the bottom using the support legs. The pump body is started, and the pump body pumps outside air into the tube body through the float and telescopic tube, and then aerates it through stratified aeration. The aerator and bottom oxygenation mechanism oxygenate the water. The high-density material base plate allows the aerator to sink to the bottom, placing the bottom oxygenation mechanism at the bottom of the water to oxygenate deep water. The hollow float, made of low-density material, floats on the water surface due to buoyancy. The telescopic tube adapts to the movement and extension of the float, ensuring it floats to the surface regardless of water depth, preventing water from entering the float and allowing it to constantly pump air in from the outside. When waves are generated on the water surface, the float moves with the waves, and the telescopic tube deforms, ensuring the top of the float remains outside the water, further preventing water from entering or sinking.

[0011] Furthermore, a top plate is provided on the side of the base plate near the telescopic pipe. The inner side of the top plate is fixedly connected to the outer surface of the pump body. Several support plates are provided at intervals between the base plate and the top plate. The support plates are evenly distributed along the axial direction of the base plate, and the two ends of the support plates are fixedly connected to the sides of the base plate and the top plate that are close to each other. The top plate is provided to fix the pump body, restrict the movement of the pump body, and prevent the pump body from colliding with objects in the water under the influence of wind and waves, thus protecting the pump body. In addition, the several support plates form a fence structure to protect the stratified aeration mechanism and the bottom aeration mechanism, preventing objects or organisms in the water body from colliding with the stratified aeration mechanism and the bottom aeration mechanism, thus providing protection.

[0012] Furthermore, the float has an internal concave plate, the surface of which is fixedly connected to the inner wall of the float. Support blocks are provided at the intervals between the float and the concave plate, and several support blocks are arranged along the circumference of the float. The concave plate and the inner wall of the float form a cavity, thereby reducing the overall density of the float and the concave plate, increasing the buoyancy of the float, and further preventing water from entering the float or sinking to the bottom. The concave plate is recessed towards the axis of the float, creating a larger cavity and reducing the overall density. At the same time, it makes the cross-section of the inner wall of the concave plate smaller, further preventing water from entering when there are waves. The support blocks support the float and the concave plate, preventing them from deforming under the impact of waves, avoiding deformation that would reduce the drainage area of ​​the float, and ensuring its buoyancy.

[0013] Furthermore, the stratified oxygenation mechanism includes a limiting cylinder, the outer surface of which is fixedly connected to the inner side of the support plate, and an oxygenation plate is fixedly connected to the inner wall of the limiting cylinder. The side of the oxygenation plate closest to the pipe body is fixedly connected to the surface of the pipe body, and a connection hole is provided at the connection between the oxygenation plate and the pipe body. The inner cavity of the pipe body is connected to the inner cavity of the oxygenation plate through the connection hole. Several cylinders are provided on the surface of the oxygenation plate, and dissolved oxygen tanks are provided on the surface of the cylinders. Air is pumped into the pipe body, then enters the oxygenation plate through the connection hole, and is discharged through the dissolved oxygen tank.

[0014] Furthermore, the oxygenating plates are arranged in several groups, with each group consisting of several oxygenating plates arranged along the axial direction of the pipe. These oxygenating plates are evenly distributed circumferentially along the pipe, and connecting rods are provided at the intervals between adjacent circumferential oxygenating plates. The two ends of each connecting rod are fixedly connected to the sides of two adjacent oxygenating plates that are close to each other. The arrangement of several oxygenating plates circumferentially and axially increases the dissolved oxygen area, resulting in a better oxygenation effect. The axially arranged oxygenating plates can oxygenate water at different depths, and the oxygenation amount at different depths can be adjusted by regulating the size of the cylinders and dissolved oxygen tanks on the oxygenating plates, thus adapting to the oxygenation requirements of aquatic organisms living at different water depths. Connecting rods are provided to support adjacent oxygenating plates.

[0015] Furthermore, the oxygenation plate is internally equipped with a sleeve plate, which is located outside the cylinder. The outer surface of the sleeve plate is fixedly connected to the inner wall of the oxygenation plate, and the inner wall of the sleeve plate is fixedly connected to the outer surface of the cylinder. The sleeve plate is made of air stones. Air enters the oxygenation plate, passes through the sleeve plate, enters the cylinder, and then exits from the dissolved oxygen tank. The sleeve plate is made of air stones, which are loose and porous, and can separate the air into tiny bubbles, allowing the air to dissolve better into the water. The smaller the bubble, the slower its rising speed, which can increase the dissolution time between the air and the water, allowing the air to dissolve better into the water.

[0016] Furthermore, a telescopic rod is installed inside the pipe body, and a perforated plate is fixedly connected to the surface of the telescopic rod. The outer surface of the perforated plate is fixedly connected to the inner wall of the pipe body. A piston is fixedly connected to the end of the telescopic rod away from the perforated plate, and the surface of the piston is slidably connected to the inner wall of the pipe body. When the telescopic rod extends, it drives the piston to slide inside the pipe body, gradually connecting the axially arranged oxygenation plates with the pipe body. This achieves the purpose of adjusting the oxygenation effect in the vertical direction, realizing stratified oxygenation, and providing oxygenation for aquatic products living at different depths.

[0017] Furthermore, the bottom oxygenation mechanism includes a cylinder, which is disposed on the side of the tube near the bottom plate, and the inner wall of the cylinder is rotatably connected to the outer surface of the tube. A flexible tube is inserted through the inside of the cylinder, and a rotating arm is disposed on the side of the flexible tube away from the cylinder. The flexible tube is fixedly inserted inside the rotating arm, and a counterweight is fixedly connected to the end of the flexible tube away from the cylinder. The counterweight is made of an air stone. Air enters the cylinder through the tube and then enters the counterweight through the flexible tube. The counterweight, made of an air stone, can separate the air into tiny bubbles and discharge them, thereby increasing the dissolved oxygen effect.

[0018] Furthermore, a rotating seat is fixedly connected to the outer surface of the cylinder. The side of the rotating seat away from the cylinder is rotatably connected to the end of the rotating arm away from the counterweight via a rotating rod. A limiting plate is fixedly connected to the side of the rotating seat away from the bottom plate, and a triangular block is fixedly connected to the side of the limiting plate away from the rotating seat. This drives the cylinder to rotate, causing the rotating seat, rotating arm, counterweight, hose, limiting plate, and triangular block to rotate. By setting the counterweight, under the action of centrifugal force, the counterweight rises, causing the rotating arm to rotate around the rotating seat, thereby increasing the rotation radius, improving the stirring effect, and improving the dissolved oxygen effect at the bottom of the water body. This allows for the dissolution of more oxygen at the bottom of the water body and also allows for the adjustment of the rotation speed of the cylinder, thereby adjusting the centrifugal effect of the counterweight and thus changing the stirring effect to achieve the purpose of adjusting the dissolved oxygen effect. The dissolved oxygen amount can be adjusted according to different aquatic needs. The limiting plate restricts the rotation angle of the rotating arm, preventing the counterweight from colliding with the support plate and thus avoiding damage to the counterweight. The triangular block, with its high stability, provides good support for the limiting plate, preventing deformation and ensuring the limiting effect of the limiting plate.

[0019] Furthermore, a rotating shaft is fixedly connected to one end of the cylinder near the bottom plate, and a motor is fixedly connected to the side of the bottom plate near the rotating shaft. The output end of the motor is fixedly connected to the end of the rotating shaft near the bottom plate. A circular groove is formed at the end of the rotating shaft away from the motor, and the diameter of the circular groove, the cylinder, and the pipe are equal. When the motor is started, the output end of the motor drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the cylinder to rotate. When the piston enters the inside of the circular groove, the inner cavity of the hose communicates with the inner cavity of the pipe, and air enters the hose. The bottom aeration mechanism is activated to aerate the bottom of the water. The diameter of the circular groove, the cylinder, and the pipe are equal to the diameter of the pipe, which ensures the piston can slide in.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention incorporates an oxygenation device and a base plate made of high-density material, allowing the aerator to sink to the bottom. This ensures the bottom oxygenation mechanism is located at the bottom of the water, thus oxygenating deep water. The float is hollow and made of low-density material, allowing it to float on the water surface under buoyancy. The telescopic tube adapts to the movement and extension of the float, ensuring it floats to the surface regardless of water depth, preventing water from entering the float and allowing it to constantly pump air in from the outside. Furthermore, when waves are generated on the water surface, the float moves under the influence of the waves, and the telescopic tube deforms, ensuring the top of the float remains outside the water, further preventing water from entering or sinking.

[0022] 2. This invention reduces the overall density of the float and the concave plate by setting a concave plate, which forms a cavity with the inner wall of the float, thereby increasing the buoyancy of the float and further preventing water from entering or sinking. The concave plate is recessed towards the axis of the float, creating a larger cavity and reducing the overall density. At the same time, it makes the cross-section of the inner wall of the concave plate smaller, further preventing water from entering when there are waves. A support block is set to support the float and the concave plate, preventing them from deforming under the impact of waves and avoiding deformation that would reduce the drainage area of ​​the float, thus ensuring its buoyancy.

[0023] 3. This invention, by setting up oxygenation plates, with several oxygenation plates arranged circumferentially and axially, can increase the dissolved oxygen area and obtain a better oxygenation effect. The axially arranged oxygenation plates can oxygenate water at different depths. Furthermore, by adjusting the size of the cylinders on the oxygenation plates and the dissolved oxygen tanks, the oxygenation amount at different depths can be adjusted, thereby adapting to the oxygen content requirements of aquatic organisms living at different water depths. The piston slides inside the tube, gradually connecting the axially arranged oxygenation plates with the tube, thereby achieving the purpose of adjusting the oxygenation effect in the vertical direction, realizing stratified oxygenation, and providing oxygenation for aquatic organisms living at different depths.

[0024] 4. This invention incorporates a counterweight made of air stone. The porous nature of the air stone allows it to break down air into tiny bubbles, enabling better dissolution into the water. Smaller bubbles rise more slowly, increasing the dissolution time between air and water. Under centrifugal force, the counterweight rises, driving the rotating arm to rotate around the base, increasing the radius of rotation, improving the stirring effect, and enhancing oxygenation at the bottom of the water. This allows for the dissolution of more oxygen at the bottom and also allows for adjustment of the cylinder's rotation speed, thereby regulating the centrifugal effect of the counterweight and altering the stirring effect to achieve the goal of regulating dissolved oxygen. The dissolved oxygen level can be adjusted according to different aquatic needs. A limiting plate restricts the rotation angle of the rotating arm, preventing the counterweight from colliding with the support plate and thus avoiding damage. A triangular block provides high stability and good support for the limiting plate, preventing deformation and ensuring its effective positioning. Attached Figure Description

[0036] Example 1, please refer to Figures 1-3 This invention relates to a floating multi-layer deep-water aerator for agricultural aquaculture, comprising:

[0037] The base plate 1 is made of high-density material, and the support legs 2 are provided on the side of the base plate 1;

[0038] Oxygenation device 3, which has an aeration structure, is used to dissolve oxygen into the water body.

[0039] Among them, the oxygenation device 3 includes:

[0040] The float 31 is made of low-density material and is hollow. A telescopic tube 32 is provided on the side of the float 31 near the bottom plate 1.

[0041] The pump body 33 has a pipe body 34 on the side of the pump body 33 near the bottom plate 1, and a layered oxygenation mechanism 35 and a bottom oxygenation mechanism 36 are also provided on the side of the pump body 33 near the bottom plate 1.

[0042] The side of float 31 closest to the bottom plate 1 is fixedly connected to the end of telescopic pipe 32 furthest from the bottom plate 1. The end of telescopic pipe 32 furthest from float 31 is fixedly connected to the side of pump body 33 furthest from the bottom plate 1. The side of pump body 33 closest to the bottom plate 1 is fixedly connected to the side of pipe body 34 furthest from the bottom plate 1. The inner side of stratified aeration mechanism 35 is fixedly connected to the outer surface of pipe body 34. The side of bottom aeration mechanism 36 furthest from pipe body 34 is fixedly connected to the top of bottom plate 1. The side of bottom aeration mechanism 36 furthest from bottom plate 1 is rotatably connected to the end of pipe body 34 closest to bottom plate 1. The aerator is placed inside the water body and fixed to the bottom by support legs 2. Pump body 33 is started, and pump body 33 pumps outside air into pipe body 34 through float 31 and telescopic pipe 32, and then through stratified aeration mechanism 35. The oxygenation mechanism 35 and the bottom oxygenation mechanism 36 oxygenate the water. The bottom plate 1, made of high-density material, allows the aerator to sink to the bottom, and the bottom oxygenation mechanism 36 is located at the bottom of the water, thereby oxygenating the deep water. The float 31 is hollow and made of low-density material. The float 31 floats on the surface of the water under the action of buoyancy, and the telescopic tube 32 can adapt to the movement and extension of the float 31, so that the float 31 can float to the surface of the water regardless of the water depth, preventing water from entering the float 31. This allows the float 31 to always pump air from the outside. At the same time, when waves are generated on the surface of the water, the float 31 moves under the action of the waves, and the telescopic tube 32 can also deform, so that the top of the float 31 is always outside the water, further preventing the float 31 from entering the water or sinking to the bottom.

[0043] A top plate 37 is provided on the side of the base plate 1 near the telescopic pipe 32. The inner side of the top plate 37 is fixedly connected to the outer surface of the pump body 33. Several support plates 38 are provided at intervals between the base plate 1 and the top plate 37. The support plates 38 are evenly distributed along the axial direction of the base plate 1, and the two ends of the support plates 38 are fixedly connected to the sides of the base plate 1 and the top plate 37 that are close to each other. The top plate 37 is provided to fix the pump body 33, restrict the movement of the pump body 33, and prevent the pump body 33 from colliding with objects in the water under the influence of wind and waves, thus protecting the pump body 33. In addition, the several support plates 38 form a fence structure to protect the stratified aeration mechanism 35 and the bottom aeration mechanism 36, preventing objects or organisms in the water from colliding with the stratified aeration mechanism 35 and the bottom aeration mechanism 36, thus providing protection.

[0044] The float 31 has an internal concave plate 39, the surface of which is fixedly connected to the inner wall of the float 31. Support blocks 310 are provided at the intervals between the float 31 and the concave plate 39, and several support blocks 310 are provided along the circumference of the float 31. The concave plate 39 forms a cavity with the inner wall of the float 31, thereby reducing the overall density of the float 31 and the concave plate 39, increasing the buoyancy of the float 31, and further preventing the float 31 from taking on water or sinking. The concave plate 39 is recessed towards the axis of the float 31, creating a larger cavity and reducing the overall density. At the same time, it makes the cross-section of the inner wall of the concave plate 39 smaller, further preventing water from taking on water when there are waves. The support blocks 310 support the float 31 and the concave plate 39, preventing them from deforming under the impact of waves, avoiding deformation that would reduce the drainage area of ​​the float 31, and ensuring its buoyancy.

[0045] Example 2, please refer to Figures 4-6 The stratified oxygenation mechanism 35 includes a limiting cylinder 351. The outer surface of the limiting cylinder 351 is fixedly connected to the inner side of the support plate 38, and an oxygenation plate 352 is fixedly connected to the inner wall of the limiting cylinder 351. The side of the oxygenation plate 352 closest to the pipe body 34 is fixedly connected to the surface of the pipe body 34, and a connection hole 354 is provided at the connection between the oxygenation plate 352 and the pipe body 34. The inner cavity of the pipe body 34 is connected to the inner cavity of the oxygenation plate 352 through the connection hole 354. A plurality of cylinders 355 are provided on the surface of the oxygenation plate 352, and dissolved oxygen tanks 356 are provided on the surface of the cylinders 355. Air is pumped into the pipe body 34, then enters the oxygenation plate 352 through the connection hole 354, and is discharged through the dissolved oxygen tank 356.

[0046] The oxygenation plates 352 are arranged in several groups, with each group of oxygenation plates 352 arranged along the axial direction of the pipe body 34. The oxygenation plates 352 are evenly distributed circumferentially along the pipe body 34, and connecting rods 353 are provided at the intervals between adjacent oxygenation plates 352. The two ends of the connecting rods 353 are fixedly connected to the sides of two adjacent oxygenation plates 352 that are close to each other. The arrangement of multiple oxygenation plates 352 circumferentially and axially increases the dissolved oxygen area, resulting in better oxygenation. The axially arranged oxygenation plates 352 can oxygenate water at different depths. Furthermore, the oxygenation amount at different depths can be adjusted by regulating the size of the cylinders 355 and dissolved oxygen tanks 356 on the oxygenation plates 352, thus adapting to the oxygenation requirements of aquatic organisms living at different water depths. Connecting rods 353 provide support between adjacent oxygenation plates 352.

[0047] An aeration plate 352 has a sleeve 3510 inside, which is located outside the cylinder 355. The outer surface of the sleeve 3510 is fixedly connected to the inner wall of the aeration plate 352, and the inner wall of the sleeve 3510 is fixedly connected to the outer surface of the cylinder 355. The sleeve 3510 is made of air stone. Air enters the aeration plate 352, passes through the sleeve 3510, and then enters the cylinder 355. It is then discharged from the dissolved oxygen tank 356. The sleeve 3510 is made of air stone. The air stone is loose and porous, which can separate the air into tiny bubbles, allowing the air to dissolve better into the water. The smaller the bubble, the slower its rising speed, which can increase the dissolution time between the air and the water, allowing the air to dissolve better into the water.

[0048] The tube body 34 is equipped with a telescopic rod 358 inside. A perforated plate 3511 is fixedly connected to the surface of the telescopic rod 358. The outer surface of the perforated plate 3511 is fixedly connected to the inner wall of the tube body 34. A piston 359 is fixedly connected to the end of the telescopic rod 358 away from the perforated plate 3511. The surface of the piston 359 is slidably connected to the inner wall of the tube body 34. When the telescopic rod 358 extends, it drives the piston 359 to slide inside the tube body 34, gradually connecting the axially arranged oxygenation plates 352 with the tube body 34. This achieves the purpose of adjusting the oxygenation effect in the vertical direction, realizing stratified oxygenation, and providing oxygenation for aquatic products living at different depths.

[0049] Example 3, please refer to Figures 7-9The bottom oxygenation mechanism 36 includes a cylinder 361, which is located on the side of the pipe 34 near the bottom plate 1. The inner wall of the cylinder 361 is rotatably connected to the outer surface of the pipe 34. A flexible hose 362 is installed through the inside of the cylinder 361. A rotating arm 363 is installed on the side of the flexible hose 362 away from the cylinder 361. The flexible hose 362 is fixed inside the rotating arm 363. A counterweight 364 is fixedly connected to the end of the flexible hose 362 away from the cylinder 361. The counterweight 364 is made of air stone. Air enters the cylinder 361 through the pipe 34 and then enters the counterweight 364 through the flexible hose 362. The counterweight 364 is made of air stone and can separate the air into tiny bubbles for discharge, thereby increasing the dissolved oxygen effect.

[0050] A rotating seat 367 is fixedly connected to the outer surface of the cylinder 361. The side of the rotating seat 367 away from the cylinder 361 is rotatably connected to the end of the rotating arm 363 away from the counterweight 364 via a rotating rod. A limiting plate 369 is fixedly connected to the side of the rotating seat 367 away from the base plate 1. A triangular block 3610 is fixedly connected to the side of the limiting plate 369 away from the rotating seat 367. Driving the cylinder 361 to rotate causes the rotating seat 367, rotating arm 363, counterweight 364, hose 362, limiting plate 369, and triangular block 3610 to rotate. By setting the counterweight 364, under the action of centrifugal force, the counterweight 364 rises, causing the rotating arm 363 to rotate around the rotating seat 367. This increases the rotation radius, improves the stirring effect, and enhances the dissolved oxygen effect at the bottom of the water body, dissolving more oxygen at the bottom. It also allows adjustment of the rotation speed of the cylinder 361, thereby adjusting the centrifugal effect of the counterweight 364, thus changing the stirring effect and achieving the purpose of adjusting the dissolved oxygen effect. The dissolved oxygen amount can be adjusted according to different aquatic needs. A limit plate 369 is set to limit the rotation angle of the rotating arm 363, preventing the counterweight 364 from colliding with the support plate 38, thereby preventing damage to the counterweight 364. A triangular block 3610 is set. Triangles have high stability and can provide good support for the limit plate 369, preventing it from deforming and ensuring the limiting effect of the limit plate 369.

[0051] A rotating shaft 365 is fixedly connected to one end of the cylinder 361 near the bottom plate 1. A motor 366 is fixedly connected to one side of the bottom plate 1 near the rotating shaft 365, and the output end of the motor 366 is fixedly connected to the end of the rotating shaft 365 near the bottom plate 1. A circular groove 368 is opened at the end of the rotating shaft 365 away from the motor 366, and the diameter of the circular groove 368 and the cylinder 361 is equal to the diameter of the pipe 34. When the motor 366 is started, the output end of the motor 366 drives the rotating shaft 365 to rotate, and the rotation of the rotating shaft 365 drives the cylinder 361 to rotate. When the piston 359 enters the inside of the circular groove 368, the inner cavity of the hose 362 is connected to the inner cavity of the pipe 34, and air enters the hose 362. The bottom aeration mechanism 36 is activated to aerate the bottom of the water. The diameter of the circular groove 368 and the cylinder 361 is equal to the diameter of the pipe 34, which can ensure the sliding of the piston 359.

[0052] In use, place the aerator inside the water body and fix it to the bottom using the support legs 2. Start the pump body 33, which pumps outside air into the pipe body 34 via the float 31 and the telescopic pipe 32. Start the telescopic rod 358 and adjust its extension as needed, causing the piston 359 to slide inside the pipe body 34, gradually connecting the axially arranged oxygenation plates 352 to the pipe body 34. Air is pumped into the pipe body 34 and then enters the oxygenation plates 352 through the connecting holes 354. After entering the oxygenation plates 352, the air passes through the sleeve plate 3510 and enters the cylinder 355, and then exits from the dissolved oxygen tank 356. The sleeve plate 3510 is made of air stones, which are loose and porous, separating the air into tiny bubbles so that the air can dissolve better. Inside the water body, when piston 359 enters the circular groove 368, the inner cavity of hose 362 connects with the inner cavity of pipe body 34, allowing air to enter hose 362 and then through hose 362 into counterweight 364. Counterweight 364, made of air stone, separates the air into tiny bubbles, which are then discharged and dissolved into the water body. Motor 366 is then started, and the output end of motor 366 drives shaft 365 to rotate. The rotation of shaft 365 drives cylinder 361 to rotate, which in turn drives rotating seat 367, rotating arm 363, counterweight 364, hose 362, limiting plate 369, and triangular block 3610 to rotate. Under the action of centrifugal force, counterweight 364 rises, causing rotating arm 363 to rotate around rotating seat 367, thereby increasing the rotation radius and improving the stirring effect.
