Description

Technical Field

[0001] This application relates to the field of fishing equipment technology, and in particular to a fishing net seizing device. Background Technology

[0002] Freshwater aquaculture is an important component of inland aquaculture. Aquaculture sites mainly include reservoirs and ponds. Reservoirs are common sites for freshwater aquaculture because they provide a stable water source and a large water surface area, suitable for large-scale fish farming. Pond farming is also a common freshwater aquaculture method, especially around cities or in agricultural areas. Freshwater fishing operations mostly employ traditional manual seine net fishing. This involves one or more people wading through the water on foot, using boats to cast and pull the nets, continuously narrowing the seine area to drive the fish to a concentrated area, where they are then manually caught.

[0003] Currently, the main method of net seine is still manual hauling. Due to the complex and varied surrounding environments of aquaculture sites such as lakes, reservoirs, and ponds, there are no good seine tools to assist with mechanical hauling. Therefore, hauling the nets mainly relies on manual operation. Furthermore, fishing nets are easily caught on underwater weeds, branches, or debris in the silt, resulting in great resistance during hauling. The process of hauling the nets is very physically demanding. In deep water or waters with complex terrain, traditional manual operation is inefficient and poses safety risks. Utility Model Content

[0004] Therefore, the purpose of this invention is to overcome the problem that existing freshwater fishing net pulling requires a large amount of manpower and is time-consuming and labor-intensive, and to provide a fishing net pulling device. This invention can mechanically assist in pulling the fishing net ropes, thereby replacing manual force application, greatly reducing personnel requirements, lowering the workload of personnel, improving fishing efficiency, and reducing the dangers of manual operations.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A fishing net pulling device includes a base, two sets of pulling mechanisms symmetrically arranged on both sides of the base for pulling fishing net ropes, and several guide roller mechanisms independent of the base for guiding the fishing net ropes; the guide roller mechanism includes a mounting bracket and a guide wheel assembly disposed at the end of the mounting bracket, the guide wheel assembly including a mounting shaft, a guide wheel rotatably connected to the mounting shaft, and a limiting rod that can be opened and closed around the outside of the guide wheel.

[0007] This application is applicable to auxiliary netting in aquaculture sites such as reservoirs and ponds. During use, after the fishing net is manually laid, the base of this application is installed on the bank of the destination for net collection and fish distribution. The guide roller mechanism, independent of the base, is inserted along the bank of the aquaculture site. The number of rollers inserted is adapted to the shape and area of ​​the aquaculture site. Then, the fishing net rope is passed through the arranged guide roller mechanism one by one along both banks from the point where the net is lowered until it reaches the base. The net-pulling mechanism then pulls the fishing net rope towards the base, replacing manual labor. The fishing net generally includes a net cover, sinkers, floats, and fishing net ropes. After the net is lowered, the sinkers fall to the bottom of the pond under gravity, while the floats float on the surface. The floats and sinkers open the net cover to form a barrier. The fishing net ropes include at least four ropes. Two ropes are responsible for connecting the floats and pulling the ends of the net cover ropes, while the other two are responsible for... The two ends of the net ropes connected to the sinker are pulled, and four fishing net ropes are connected to the four corners of the net, forming a four-corner pulling state. Depending on the size of the net, the ropes are pulled to different parts of the net. These fishing net ropes are guided by the guide roller mechanism to the net pulling mechanism. The net pulling mechanism pulls the fishing net ropes, gradually pulling the net towards the destination for hauling in the fish and driving the fish into the destination to achieve the purpose of catching fish. The guide roller mechanism is used to guide and change the direction of the fishing net ropes during the pulling process. It can be reasonably set up on the shore according to different fishing sites to ensure that the net is gradually gathered during the pulling process. The limit rod ensures that the fishing net ropes will not fall to the ground when dragged on the guide wheel. It is also designed to be openable and closable, so that when the net is pulled to the position of the guide wheel, the fishing net rope at that point can be released in time to facilitate the net to continue moving forward.

[0008] The advantages of this application are as follows: In this process, the net-pulling mechanism can mechanically assist in pulling the fishing net ropes, thereby replacing manual force application. Through the setting of the guide roller mechanism, the force is guided and the net is gradually pulled in. This process greatly reduces the number of personnel required. Only the base and guide roller mechanism need to be firmly fixed to the shore by manpower to ensure stable operation during the net-pulling process. This simplifies the manpower configuration, reduces the workload of personnel, and greatly improves the efficiency of fishing. At the same time, since the number of personnel working in the water is reduced, the danger of manual operation is also reduced, and personnel safety is better guaranteed.

[0009] Furthermore, the net-pulling mechanism includes a drive roller, a pressure roller with its axis parallel to the axis of the drive roller, and a drive device with its output end connected to the drive roller. The drive roller and the pressure roller are connected by a transmission component. The fishing net rope is threaded through one side of the pressure roller and out from the opposite side of the pressure roller and drive roller. After the fishing net ropes on both sides are threaded into the two net-pulling mechanisms, the preparation for pulling the net is completed. The drive device is activated, causing the drive roller to rotate. Under the transmission action of the transmission component, the pressure roller rotates in the opposite direction. Driven by the drive roller and the pressure roller, the fishing net rope gradually pulls the net at the lower part towards the base.

[0010] Furthermore, one end of the pressure roller is provided with a pressure-applying element, and the pressure-applying direction of the pressure-applying element is perpendicular to the axis of the pressure roller.

[0011] Furthermore, the pressure-applying component is a spring.

[0012] The pressure roller and the drive roller are positioned to maintain a relative position, ensuring that they can maintain pressure on the fishing net rope. This provides sufficient resistance and friction to pull the fishing net rope during rotation, ensuring the normal pulling of the net.

[0013] Furthermore, the surface of the drive roller is provided with a plurality of first annular grooves, and the surface of the pressure roller is provided with a second annular groove that is opposite to the position of the first annular grooves. The first and second annular grooves are used for the fishing net rope to be pulled through, and anti-slip protrusions are provided inside the first and second annular grooves.

[0014] The first and second annular grooves are designed for the passage of fishing net ropes. Firstly, they restrict the pulling position of the ropes, ensuring they are pulled along the same path when pulled by the rotation of the pressure roller and the drive roller. Secondly, having multiple first and second annular grooves allows for the simultaneous pulling of multiple fishing net ropes. When fishing in large ponds and reservoirs, large fishing nets are needed. If the catch is large, the fish, by instinct, will swim in the opposite direction of the net's movement during the pulling process. When the fish density reaches a certain point, the net will sink. To prevent this, several fishing net ropes can be added to one side of the float on the net. Based on this, in order to ensure balanced force when hauling in the net, multiple fishing net ropes are installed on the float side. Therefore, the fishing net ropes on the same side can be pulled synchronously by the net-pulling mechanism on the same side, simulating the effect of multiple people pulling on one side. The first and second annular grooves are equipped with anti-slip protrusions inside, which can increase the friction of the fishing net ropes passing through them, and at the same time form a greater biting force at the relative positions. In this way, when the pressure roller and the drive roller move in opposite directions, they can more firmly bite and pull the fishing net ropes from one side to the other side, reducing slippage.

[0015] Furthermore, it also includes an arc-shaped baffle surrounding a portion of the outer surface of the pressure roller. The arc-shaped baffle has an arc-shaped groove corresponding to the position of the second annular groove, and the interior of the arc-shaped groove is smooth. With the arc-shaped baffle on the outer surface of the pressure roller, the fishing net rope enters from one side of the arc-shaped baffle and the pressure roller, passes through the area enclosed by the arc-shaped baffle, then passes the opposite side of the pressure roller and the drive roller, and is pulled out from the other side. Any weeds or silt hanging on the fishing net rope will be blocked and scraped away at the entrance of the arc-shaped baffle, thus playing a role in cleaning the fishing net rope. Simultaneously, the fishing net rope, entering the arc-shaped groove area of ​​the arc-shaped baffle, is less likely to detach under the constraint of the arc-shaped baffle, thus maintaining the pulling track of the fishing net rope.

[0016] Furthermore, the guide wheel is a V-shaped guide wheel.

[0017] Furthermore, the guide wheel assemblies comprise at least two sets, with several guide wheel assemblies coaxially connected in series on the mounting bracket. The multiple sets of guide wheel assemblies are provided to accommodate large fishing nets with multiple fishing net ropes, each serving to guide a different fishing net rope.

[0018] Furthermore, the base is a frustum frame, and the drive roller, pressure roller and driving device are all mounted on the frustum frame, with the driving device fixed to the frustum frame.

[0019] It should be noted that the drive device and the drive roller can be driven directly or indirectly through transmission mechanisms such as sprockets, gears, and belts. The specific drive method used does not affect the achievement of the purpose of this application. Both direct and indirect drive methods are within the scope of protection of this application. The drive device includes, but is not limited to, core components such as motors, reducers, drive wheels, couplings, and brakes.

[0020] Setting the base as a truncated cone frame structure provides better stability. The open frame structure is also lighter and provides better heat dissipation when the drive device is operating. Furthermore, wastewater or mud expelled from the drive roller, pressure roller, and curved baffle during the pulling process will not cause cleaning difficulties, as it will mostly remain on the aquaculture area where the base is fixed. It should be noted that the truncated cone frame can be fixed by using U-shaped nails or other fasteners to nail the bottom edge of the frame into the ground, or by using sandbags filled with heavy objects as counterweights to press down on the frame. Alternatively, four diagonal braces can be used to support the top of the frame and connect it to the ground, with connecting rods at the bottom of the frame, and the connecting rods secured to the ground with steel nails. As long as the truncated cone frame is securely installed and will not tip over during pulling, the specific fixing method used does not affect the achievement of the purpose of this application and is within the scope of protection of this application.

[0021] Furthermore, the transmission component includes a first gear fixed to the end of the drive roller and a second gear fixed to the end of the pressure roller, the first gear and the second gear meshing with each other.

[0022] The synchronous rotation of the drive roller and the pressure roller is achieved by gear transmission, meaning that a single drive device is sufficient for one mesh pulling mechanism to achieve rotation and fulfill its purpose; in this embodiment, the drive device can be a high-power motor.

[0023] Furthermore, the fishing net seine device also includes a control system, which includes controllers that are respectively connected to the two drive devices, an operation panel and a wireless operation handle that are respectively connected to the controllers, and a wireless communication module disposed in the controllers. The operation panel is disposed on the base.

[0024] In complex aquaculture environments such as ponds and reservoirs, underwater obstacles pose a major risk to net-hauling operations. Irregularly distributed boulders and abandoned wooden stakes on the seabed can easily entangle the nets. If the traction drive is not stopped immediately upon entanglement, the high-intensity pulling force can tear the nets. Furthermore, the common curved terrain in these waters requires operators to adjust the pulling force of the nets on both sides in real time to maintain a balanced hauling process. Due to the spatial distance between the nets and the net-hauling mechanism on the shore, manual control via the control panel on the base often fails to respond promptly to unexpected situations. To address the control needs of such dynamic operational scenarios, the configuration of a wireless control handle greatly optimizes the operational process. Operators can follow the net-hauling operation from the shore, observe the net-hauling situation at any time, and dynamically control the start, stop, and reverse of the two sets of motors via the wireless control handle, resolving practical problems and meeting the need for precise control of the net-hauling process in complex aquatic environments.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This application utilizes a net-pulling mechanism to pull the fishing net ropes, gradually guiding the net towards the target area for hauling in the fish and herding them there, thus achieving the goal of catching fish. This replaces manual labor, as the force is guided by a guide roller mechanism to gradually gather the net. This process significantly reduces manpower requirements; only manual labor is needed to securely fix the base and guide roller mechanism to the shore to ensure stable operation during the net-pulling process. This streamlines manpower, reduces the workload of personnel, and greatly improves fishing efficiency. At the same time, by reducing the amount of time personnel are working in the water, the risks of manual labor are also reduced, better ensuring personnel safety. Attached Figure Description

[0037] Example 1

[0038] like Figure 1 and Figure 4 As shown, a fishing net pulling device includes a base 1, two sets of pulling mechanisms 2 symmetrically arranged on both sides of the base 1 for pulling the fishing net rope 400, and several guide roller mechanisms 3 independent of the base 1 for guiding the fishing net rope 400; the guide roller mechanism 3 includes a mounting bracket 31 and a guide wheel assembly provided at the end of the mounting bracket 31, the guide wheel assembly including a mounting shaft 32, a guide wheel 33 rotatably connected to the mounting shaft 32, and a limiting rod 34 that can be opened and closed and surrounds the outside of the guide wheel 33.

[0039] This application is applicable to auxiliary netting in aquaculture sites such as reservoirs and ponds. During use, after the fishing net is manually laid, the base 1 of this application is installed on the bank where the net is to be retrieved and the fish separated. The guide roller mechanism 3, which is independent of the base 1, is inserted along the bank of the aquaculture site. The number of guide rollers inserted is adapted to the shape and area of ​​the aquaculture site. Then, the fishing net rope 400 is passed through the arranged guide roller mechanisms 3 one by one from the point where the net is lowered along both banks until it reaches the base 1. The guide roller mechanism is used to guide and change the pulling direction of the fishing net rope 400 during the pulling process. Different fishing sites require appropriate setup along the shore to ensure the net 100 is gradually pulled together during operation. The limiting rod 34 prevents the net rope 400 from falling to the ground when dragged on the guide wheel 33. It is also designed to be openable and closable, allowing the net rope 400 to be released promptly when the net 100 reaches the guide wheel position, facilitating further movement of the net 100. A typical fishing net includes the net 100, sinker 200, float 300, and net rope 400. After the net is cast, the sinker 200 sinks to the bottom of the pond under gravity, while the float 300 floats on the surface. The float 300 and sinker... The net 100 is spread out to form a blocking surface. The fishing net ropes 400 include at least four ropes. Two of the ropes 400 are used to pull the ends of the net ropes connecting the float 300, and the other two are used to pull the ends of the lower net ropes connecting the sinker 200. Depending on the size of the net 100, these ropes 400 are pulled at different points on the net 100. These ropes 400 are guided by the guide roller mechanism 3 and pulled to the net-pulling mechanism 2. The net-pulling mechanism 2 pulls the ropes 400, gradually pulling the net 100 towards the destination for hauling in the fish, and gradually driving the fish into the destination. The purpose of fishing is achieved through the mechanical assistance of the net pulling mechanism 2 in pulling the net rope 400, replacing manual force application. The force is guided by the guide roller mechanism 3, gradually pulling the net 100 together. This process greatly reduces the number of personnel required. Only the base 1 and the guide roller mechanism 3 need to be firmly fixed to the shore to ensure stable operation during the net pulling process. This simplifies the manual configuration, reduces the workload of personnel, and greatly improves the efficiency of fishing. At the same time, since the number of personnel working in the water is reduced, the danger of manual operation is also reduced, and the safety of personnel is better guaranteed.

[0040] like Figure 2As shown, the net-pulling mechanism 2 includes a drive roller 21, a pressure roller 22 with its axis parallel to the axis of the drive roller 21, and a drive device 23 whose output end is connected to the drive roller 21. The drive roller 21 and the pressure roller 22 are connected by a transmission component. The fishing net rope 400 is inserted into the pressure roller 22 from one side and exits from the opposite side of the pressure roller 22 and the drive roller 21. After the fishing net ropes 400 on both sides are threaded into the two net-pulling mechanisms 2, the preparation for pulling the net is completed. The drive device 23 is started, and the drive device 23 drives the drive roller 21 to rotate. Under the transmission action of the transmission component, the pressure roller 22 rotates in the opposite direction. The fishing net rope 400, driven by the drive roller 21 and the pressure roller 22, gradually pulls the net 100 at the lower part of the net towards the base 1.

[0041] like Figure 2 As shown, one end of the pressure roller 22 is also provided with a pressure-applying component 4, and the pressure-applying direction of the pressure-applying component 4 is perpendicular to the axis of the pressure roller 22.

[0042] In this embodiment, one end of the pressure applying element 4 is fixed to the end of the pressure roller 22, and the other end of the pressure applying element 4 is fixed to the base 1.

[0043] In this embodiment, the pressure-applying component 4 is a spring.

[0044] The pressure component 4 is set to maintain the relative position of the pressure roller 22 and the drive roller 21, thereby ensuring that the two can maintain a pressing force on the fishing net rope 400. In this way, during the rotation process, there is enough pressing force and friction to pull the fishing net rope 400 and ensure the normal pulling of the fishing net.

[0045] like Figure 2 As shown, the transmission component includes a first gear 241 fixed to the end of the drive roller 21 and a second gear 242 fixed to the end of the pressure roller 22. The first gear 241 and the second gear 242 mesh with each other.

[0046] The synchronous rotation of the drive roller 21 and the pressure roller 22 is achieved by gear transmission. That is, one pull net mechanism 2 can achieve rotation and use purpose with one drive device 23. In this embodiment, the output end of the drive device 23 is directly connected to the drive roller 21, which is a direct drive method.

[0047] like Figure 2 and Figure 6 As shown, the surface of the drive roller 21 is provided with a plurality of first annular grooves 211, and the surface of the pressure roller 22 is provided with second annular grooves 221 that are opposite to the positions of the first annular grooves 211. The first annular grooves 211 and the second annular grooves 221 are used for the fishing net rope 400 to be pulled through. The interior of the first annular grooves 211 and the second annular grooves 221 is provided with anti-slip protrusions 20.

[0048] In this embodiment, the anti-slip protrusions 20 in the first annular groove 211 and the second annular groove 221 are staggered and interlocked to form a meshing engagement during rotation, which can improve the pulling effect on the fishing net rope 400.

[0049] The first annular groove 211 and the second annular groove 221 are provided for the passage of the fishing net rope 400. Firstly, they restrict the pulling position of the fishing net rope 400, ensuring that the rope is pulled along the same path when pulled by the rotation of the pressure roller 22 and the drive roller 21. Secondly, the presence of multiple first annular grooves 211 and second annular grooves 221 allows for the simultaneous pulling of multiple fishing net ropes 400. Furthermore, when casting a large fishing net, to ensure balanced force during retrieval, additional grooves are provided on the side of the float 300. Multiple fishing net ropes 400 are provided, so the fishing net ropes 400 on the same side can be pulled synchronously by the net pulling mechanism 2 on the same side, simulating the effect of multiple people pulling on one side; the first annular groove 211 and the second annular groove 221 are provided with anti-slip protrusions 20, which can increase the friction of the fishing net ropes 400 passing through them, and at the same time form a greater biting force at the relative position. In this way, when the pressure roller 22 and the drive roller 21 move in opposite directions, they can more firmly bite and pull the fishing net ropes 400 from one side to the other side, reducing slippage.

[0050] In this embodiment, the guide wheel 33 is a V-shaped guide wheel.

[0051] In this embodiment, there are two sets of guide wheel assemblies.

[0052] In this embodiment, the end of the mounting bracket 31 can be tapered to facilitate insertion into the soil of the fishing site, improving insertion convenience and controlling the insertion depth of the mounting bracket 31 to ensure transmission stability. Additionally, several steel rebar piles can be driven around the guide roller mechanism 3, and the top of the mounting bracket 31 can be secured by connecting the rebar piles with steel wire ropes. Thus, the bottom of the mounting bracket 31 is fixed in the soil, while the top is supported by diagonal braces or pulled by steel wire ropes, ensuring the guide roller mechanism 3 remains sturdy and stable during use.

[0053] In this embodiment, the fishing net seizing device also includes a control system, which includes a controller that is connected to the two drive devices 23 respectively, an operation panel and a wireless operation handle that are connected to the controller respectively, and a wireless communication module disposed in the controller. The operation panel is disposed on the base 1.

[0054] In complex aquaculture environments such as ponds and reservoirs, underwater obstacles pose a major risk to net-hauling operations. Irregularly distributed boulders and abandoned wooden stakes on the seabed can easily cause fishing nets to become entangled. If the traction drive device 23 is not shut off the moment the net becomes entangled, the high-intensity pulling force may tear the net. Furthermore, the common curved terrain in these waters requires operators to adjust the pulling force of the net on both sides in real time to maintain a balanced advance during the net-hauling process. Due to the spatial distance between the fishing net and the net-hauling mechanism on the shore, manual control via the control panel on the base often fails to respond promptly to unexpected situations. To address the control needs of such dynamic operational scenarios, the configuration of a wireless control handle greatly optimizes the operational process. Operators can follow the net-hauling operation from the shore, observe the net-hauling situation at any time, and dynamically control the start, stop, and reverse of the two sets of motors via the wireless control handle to solve practical problems and meet the need for precise control of the net-hauling process in complex aquatic environments.

[0055] Example 2

[0056] This embodiment is similar to Embodiment 1, except that:

[0057] In this embodiment, the output end of the drive device 23 is connected to the drive roller 21 via a sprocket, which is an indirect drive method; the drive device 23 includes core components such as a high-power motor, a reducer, a drive wheel, a coupling, and a brake.

[0058] In this embodiment, the drive device 23 is arranged below the active roller 21. The drive devices 23 of the two pulling mechanisms 2 are staggered and opposite to each other, and can be centrally arranged below the active roller 21. The whole device has a higher degree of integration and a more compact structure.

[0059] In this embodiment, a mudguard cover is provided above the two drive devices 23. The mudguard cover is inclined to guide the mud and water.

[0060] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0061] Example 3

[0062] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0063] like Figure 5 As shown, there are three sets of guide wheel assemblies, which are coaxially connected in series on the mounting bracket 31.

[0064] When fishing in large ponds and reservoirs, large fishing nets are needed for casting. If there are many fish, the fish will swim in the opposite direction of the net during the casting process. When the fish density reaches a certain level, the fish will weigh down the fishing net, causing it to sink. To avoid this, several fishing net ropes 400 can be added to one side of the float 300 of the net 100.

[0065] The three sets of guide rollers are designed to accommodate large fishing nets. They can pass three adjacent fishing net ropes on the same side of the large fishing net through the guide roller mechanism, and simultaneously guide the three fishing net ropes 400 of the net to one position.

[0066] The guide roller mechanism is used to guide and change the pulling direction of the fishing net rope 400 during the pulling process. It can be reasonably set up on the shore according to different fishing sites to ensure that the net 100 is gradually gathered during the pulling process. The limit rod 34 can ensure that the fishing net rope 400 will not fall to the ground when it is dragged on the guide wheel 33. At the same time, it is set to be openable and closable so that when the net 100 is pulled to the position of the guide wheel, the fishing net rope 400 at that position can be released in time to facilitate the net 100 to continue to move forward.

[0067] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0068] Example 4

[0069] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0070] like Figure 3 and Figure 6 As shown, it also includes an arc-shaped baffle 5 surrounding a portion of the outer surface of the pressure roller 22. The arc-shaped baffle 5 has an arc-shaped groove 51 corresponding to the position of the second annular groove 221, and the interior of the arc-shaped groove 51 is smooth. With the arc-shaped baffle 5 on a portion of the outer surface of the pressure roller 22, the fishing net rope 400 enters from one side of the arc-shaped baffle 5 and the pressure roller 22, passes through the area enclosed by the arc-shaped baffle 5, then passes through the opposite side of the pressure roller 22 and the drive roller 21, and is pulled out from the other side of the opposite side. Some weeds or silt hanging on the fishing net rope 400 will be blocked and scraped off at the entrance of the arc-shaped baffle 5, which plays a certain role in cleaning the fishing net rope 400. At the same time, the fishing net rope 400 enters the area of ​​the arc-shaped groove 51 of the arc-shaped baffle 5, and is less likely to detach under the limitation of the arc-shaped baffle 5, which plays a role in maintaining the pulling track of the fishing net rope 400.

[0071] In this embodiment, the entrance of the arc-shaped baffle 5 is bent outwards, forming an flared effect with the surface of the pressure roller 22. This makes it less likely for the fishing net rope 400 to be damaged by friction at the end of the arc-shaped baffle 5, and also prevents debris from being scraped off when the fishing net rope 400 passes through, thus preventing blockage of the outlet.

[0072] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0073] Example 5

[0074] This embodiment is similar to Embodiment 1, except that in this embodiment:

[0075] like Figure 3 As shown, the base 1 is a frustum frame. The drive roller 21, pressure roller 22, and drive device 23 are all mounted on the frustum frame, and the drive device 23 is fixed to the frustum frame. Setting the base 1 as a frustum frame structure provides better stability. The open frame structure is lighter and provides good heat dissipation when the drive device 23 is operating. At the same time, the sewage or mud squeezed out by the drive roller 21, pressure roller 22, and arc baffle 5 during the pulling process will not cause cleaning difficulties, but will mostly remain on the breeding site where the base 1 is fixed. It should be noted that the frustum frame can be fixed by using U-shaped nails or other fasteners to nail the bottom edge of the frustum frame into the ground, or by using flood control sandbags or other heavy objects as counterweights to press down on the frustum frame to ensure its stability and prevent it from tipping over and causing safety accidents during the pulling process.

[0076] The other structures and principles of this embodiment are the same as those of Embodiment 1.

[0077] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
