Description

Technical Field

[0001] This utility model belongs to the field of aquaculture equipment technology, specifically relating to a netting mechanism for pond fishing. Background Technology

[0002] Pond harvesting is a crucial step in the aquaculture production process, directly impacting the economic benefits and product quality. As a major aquaculture nation globally, my country has a vast scale of pond farming, and the efficiency and methods of its harvesting operations significantly influence the industry's development. Traditional pond harvesting primarily relies on manual netting, a long-standing and widely used method.

[0003] However, with the expansion of aquaculture scale and the improvement of industrial modernization, the fishing mode that relies entirely on manpower has exposed many limitations. The core technical problem currently faced by pond fishing operations is concentrated in the high degree of reliance on manpower. Traditional manual netting requires a large amount of labor. The fishing operation of a pond often requires 10 to 12 people to work together, which not only results in high labor costs, but also makes it difficult to improve fishing efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a netting mechanism for pond fishing, which solves the problems of high labor costs and low efficiency in manual fishing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: This utility model includes a positioning component, a transfer component, a fishing net, a netting component, and a winding component; as well as a winding component. The positioning component includes a positioning base fixed on the path along the edge of the pond; The transfer assembly includes a fixed bracket that is fixedly mounted on the traveling mechanism; There are two tensioning net components. Each tensioning net component includes an upper fixed base, a lower movable base, and a vertical rail. The upper end of the vertical rail is fixed to the lower side of the upper fixed base. The lower movable base is moved on the vertical rail by a motor. The lower end of the vertical rail of one tensioning net component is installed on the fixed base, and the other tensioning net component is installed on the fixed bracket. The fishing net has a rectangular mesh structure. The fishing net passes through the gap between two winding posts. The upper ends of the two symmetrical edges of the fishing net are fixed to the two upper fixed seats, and the lower ends are fixed to the two lower movable seats.

[0006] Optionally, a winding assembly is also included, which includes an upper plate, a lower plate, and two winding posts. The upper plate and the lower plate are coaxially arranged and rotatably mounted on the fixed bracket. The two winding posts are parallel and fixed between the upper plate and the lower plate, and are spaced apart around the axis of the upper plate. The upper plate is driven to rotate by a motor.

[0007] Optionally, the fixing component includes a pin with a pointed bottom, and the fixing base has several holes. The pin passes through the holes to fix the fixing base to the pond surface.

[0008] Optionally, the positioning assembly further includes a cylindrical base and a bearing. The cylindrical base is fixed on the positioning base, and the bearing is fixedly disposed inside the top of the cylindrical base. The lower end of the vertical rail installed on the positioning base is fixedly connected to the inner side of the bearing.

[0009] Optionally, the net assembly further includes a guide post, the lower end of which is fixedly connected to the lower movable seat, and the upper end which slides through the upper fixed seat. The extension direction of the guide post is parallel to the vertical rail, and the edge of the fishing net is slidably fitted onto the guide post.

[0010] Optionally, the fishing net includes a net surface, an upper rope, and a lower rope. The upper rope is located at the upper edge of the net surface and is made of foam material that floats on the water surface. The lower rope is located at the lower edge of the net surface and is made of rubber material that sinks to the bottom of the water.

[0011] Optionally, the fishing net may further include a plurality of sliding rings, which are arranged and fixed on the left and right edges of the fishing net and are slidably fitted onto the guide posts.

[0012] Optionally, the net assembly further includes four loops, which are respectively fixedly installed on the sides of the upper and lower fixing seats. The fishing net also includes four hooks, which are fixed to the four ends of the net surface and hung on the loops.

[0013] Optionally, the vertical rail has an I-shaped cross-section, and the lower moving seat has a gear inside that is driven by a motor to rotate and mesh with the groove of the vertical rail.

[0014] The beneficial effects of this invention are as follows: The net-laying mechanism, through the cooperation of the fixed-point component and the transfer component, achieves automated deployment and retrieval of the fishing net in the pond. The net-laying component can be precisely controlled by a motor to raise and lower the lower moving seat on the vertical rail, thereby flexibly adjusting the depth of the lower net line to ensure that the net effectively forms an encirclement in the water, adapting to different water depths and fish distributions. The reeling component makes the release and retrieval process of the fishing net smoother and more controllable, reducing the manpower and operation time required for traditional manual net pulling, significantly improving fishing efficiency and reducing labor costs. The overall structural design is tailored to the pond environment, facilitating mechanized and intelligent fishing operations and providing practical equipment support for modern aquaculture.

[0019] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0020] This utility model provides a fishing device for use with a loading vehicle in aquaculture ponds, such as... Figure 1 As shown, it includes a net-laying mechanism and a traveling mechanism; the traveling mechanism moves along a path along the edge of the pond; the net-laying mechanism includes a fixing component 11, a transferring component, a fishing net 13, a net-setting component 14, and a reeling component 15; the fixing component 11 includes a fixing base 111 fixed on the path along the edge of the pond; as shown... Figure 4The positioning component 11 further includes a pin 112 with a pointed bottom. The positioning base 111 has several holes through which the pin 112 passes, fixing the positioning base 111 to the pond surface. There are various ways to fix the positioning base 111; this is one embodiment. Alternatively, counterweights can be used to temporarily fix the positioning base 111 to the ground. The transfer component includes a fixed bracket 121 fixedly installed on the traveling mechanism. The fixed bracket 121 has multiple steel bars welded together to form a support frame structure. Figure 2 , Figure 3 and Figure 5 As shown, there are two tensioning wire mesh components 14. Each tensioning wire mesh component 14 includes an upper fixed base 141, a lower movable base 142, and a vertical rail 143. The upper end of the vertical rail 143 is fixed to the lower side of the upper fixed base 141. The vertical rail 143 has an I-shaped cross-section and a rack is provided in the groove of the vertical rail 143. The lower movable base 142 has a gear inside that is driven by a motor to rotate and mesh with the gear in the groove of the vertical rail 143, so that the lower movable base 142 is moved and mounted on the vertical rail 143 by the motor. The lower end of the vertical rail 143 of one tensioning wire mesh component 14 is mounted on the fixed base 111, and the other tensioning wire mesh component 14 is mounted on the fixed bracket 121. The winding component 15 includes an upper plate 151, a lower plate 152, and two winding columns 153. The upper plate 151 and the lower plate 152 are coaxially arranged and rotatably mounted on the fixed bracket 121. The winding posts 153 are parallel to and fixed between the upper plate 151 and the lower plate 152. Two winding posts 153 are spaced apart around the axis of the upper plate 151, which is driven to rotate by a motor. The fishing net 13 is a rectangular mesh structure, including a net surface 131, an upper rope 132, and a lower rope 133. The upper rope 132 is located at the upper edge of the net surface 131 and is made of foam material that floats on the water surface. The lower rope 133 is located at the lower edge of the net surface 131 and is made of rubber material that sinks to the bottom. One edge of the fishing net 13 is connected to the net-setting assembly 14 located on the fixed base, passes through the gap between the two winding posts 153, and is then connected to the net-setting assembly 14 located on the fixed bracket 121. The upper ends of the two symmetrical edges of the fishing net 13 are fixed to two upper fixed seats 141, and the lower ends are fixed to two lower movable seats 142. (See reference...) Figure 4 The net assembly 14 also includes four loops 144, which are fixedly installed on the sides of the upper fixed seat 141 and the lower movable seat 142 respectively. The fishing net 13 also includes four hooks 134, which are fixed to the four ends of the net surface 131 and hung on the loops 144.

[0021] The operating instructions for this fishing device are as follows: (Refer to the reference) Figure 9 A schematic diagram of the traveling mechanism for fishing is shown. In the initial state, the lower moving seat 142 of this device is at the lower end of the vertical rail 143, and the winding column 153 winds up the fishing net 13. When the traveling mechanism moves to the bank of the fishing pond, the fixed base 111 is fixed to the ground at the edge of the pond, i.e., point a. The traveling mechanism is then moved along the pond, and the winding column 153 in the winding assembly 15 rotates, extending the fishing net 13 so that it is fully extended. The position of the traveling mechanism is then moved so that the fishing net 13 sinks into the water. At this time, the upper rope 132 of the fishing net 13 floats on the water surface, and the lower rope 133 sinks to the bottom. The traveling mechanism is now located at point b. As the traveling mechanism moves slowly, it moves along point bc. The fishing net 13 is fixed at one end and moves along the edge of the pond at the other end to catch the aquatic organisms. By reasonably setting the moving position of the moving mechanism, the moving mechanism moves to the same edge of the pond as the fixed base 111, i.e., edge ad. At this time, the aquatic organisms are caught on the net surface 131 of the fishing net 13. The moving base 142 is driven by the motor to move up and down, and the two edges of the fishing net 13 are gathered together. At this time, the moving mechanism continues to move towards the fixed base, and with the winding component 15 winding, the fishing net 13 achieves a gathering and recovery, and finally recovers the aquatic organisms to the edge of the nearby pond, and gathers the fishing net 13 into a bag-shaped structure, which is convenient for the subsequent collection of the caught organisms.

[0022] This device, through the movement of the traveling mechanism in conjunction with the release of the fishing net 13 by the reeling mechanism, enables the opening and deployment of the fishing net 13 in the water. Furthermore, the movement of the traveling mechanism allows the fishing net 13 to cover the entire pond, achieving one-time harvesting of all aquatic organisms. Finally, through the retrieval of the net by the casting mechanism and the reeling mechanism, and in conjunction with the movement of the traveling mechanism, the fishing net 13 is scooped up, completing the harvesting process. This harvesting device is simple and easy to operate, replacing manual net casting and harvesting with high efficiency. Through mechanized automation, it not only significantly improves harvesting efficiency and reduces labor costs, but its flexible and precise design also surpasses many existing mechanical harvesting methods, providing practical equipment support for the intelligent and simplified production of modern aquaculture.

[0023] In further proposals, such as Figure 4 As shown, the positioning assembly 11 also includes a cylindrical base 113 and a bearing 114. The cylindrical base 113 is fixed on the positioning base 111, and the bearing 114 is fixedly disposed inside the top end of the cylindrical base 113. The lower end of the vertical rail 143 installed on the positioning base 111 is fixedly connected to the inner side of the bearing 114.

[0024] In this structure, the connection point between the entire fixed base 111 and the vertical rail 143 is changed from a fixed type to a structure that can rotate smoothly around its central axis. When the traveling mechanism moves around the pond, it avoids the fishing net 13 from getting tangled and interfering with the net-setting mechanism at the fixed base 111, and ensures that the upward movement of the lower moving seat 142 is not tangled or interfered with by the fishing net 13 during the subsequent net hauling.

[0025] In further proposals, such as Figure 2 and Figure 4 As shown, the net assembly 14 also includes a guide post 145. The lower end of the guide post 145 is fixedly connected to the lower movable seat 142, and the upper end slides through the upper fixed seat 141. The extension direction of the guide post 145 is parallel to the vertical rail 143. The edge of the fishing net 13 is slidably sleeved on the guide post 145. Specifically, the fishing net 13 also includes a plurality of sliding rings 135. The plurality of sliding rings 135 are arranged and fixed on the left and right edges of the fishing net 13, and the sliding rings 135 are slidably sleeved on the guide post 145.

[0026] By setting guide posts 145, the two edges of the fishing net 13 can be slidably set on the guide posts 145. During the process of the lower moving seat 142 moving upward along the vertical rail 143, the edges of the fishing net 13 are folded and gathered, which effectively assists in the formation of the pocket-shaped fishing net 13 structure and prevents the aquatic products from leaking out from the side edges of the fishing net 13.

[0027] In further proposals, such as Figure 1 As shown, the traveling mechanism includes a transport box 21 with its opening facing upwards, and a fixed bracket 121 is detachably mounted on the side of the transport box 21. This transport box 21 is used for transporting and loading livestock.

[0028] In further proposals, such as Figure 6 , Figure 7 and Figure 8 As shown, the traveling mechanism also includes a loading assembly 22, which includes a hydraulic cylinder 221, a rotating seat 222, and a shovel 223. The rotating seat 222 has hinged lugs 224 fixed at both ends of its bottom edge. The top edge of the side of the transport box 21 has two hinged supports 225 that cooperate with the hinged lugs 224, so that the rotating seat 222 is rotatably mounted on the top edge of the side of the transport box 21. The seat end of the hydraulic cylinder 221 is rotatably connected to the side of the transport box 21, and the output end is rotatably connected to the rotating seat 222. The shovel 223 is moved and mounted on the rotating seat 222 by a motor drive.

[0029] This device includes a loading component 22, which assists in carrying, supporting, and transferring the aquaculture materials within the net-like structure. Figure 6After the traveling mechanism moves and the net-setting and winding mechanisms rewind, the fishing net 13 forms a pocket-shaped net with the opening located on the upper side of the net-setting mechanism. When the traveling mechanism moves to the position of the fixed-point component 11, the shovel plate 223 is located on the lower side of the fishing net 13. Driven by the hydraulic cylinder 221, the shovel plate 223 rotates upward, sending the aquatic organisms from the opening of the fishing net 13 into the transport box 21. With multiple rotations of the shovel plate 223, most of the aquatic organisms can be transferred into the transport box 21. This structure allows for the loading and transportation of aquatic organisms directly at the position of the fishing net 13 that forms the fishing pocket structure after the fishing net 13 has finished catching the aquatic organisms. This further replaces the manual labor of loading aquatic organisms and effectively prevents the aquatic organisms from falling during the transfer process, thereby improving the survival rate of the aquatic organisms.

[0030] In further proposals, such as Figure 6 and Figure 7 As shown, the shovel plate 223 has an arc-shaped structure. The shovel plate 223 includes a shovel surface 223a and a retaining edge 223b. The retaining edge 223b is fixedly disposed on the sliding edge of the shovel surface 223a. The rotating seat 222 has a groove for the shovel plate 223 to move. The rotating seat 222 has a gear inside that meshes with the outer arc surface of the shovel plate 223. The gear is driven to rotate by a motor. The shovel plate 223 also includes two positioning blocks 223c, which are respectively fixed on the back of the shovel surface 223a. The positioning blocks 223c are used to block the edge of the rotating seat 222 to prevent the shovel plate 223 from falling out of the rotating seat 222.

[0031] In this structure, the shovel plate 223 moves on the rotating seat 222. During the movement of the traveling mechanism, the shovel plate 223 is located at the top of the loading box 21. During the movement of the traveling mechanism, the net is set, and the net is retrieved, the shovel plate 223 is moved to the top of the loading box 21 to avoid interference with the fishing net 13. When it is necessary to load the aquatic products, the shovel plate 223 extends to one side of the traveling mechanism under the drive of the motor on the rotating seat 222, and rotates to the lower side of the scoop-shaped fishing net 13 in coordination with the drive of the rotating seat 222. The curved shovel plate 223 can fit better against the lower side of the fishing net 13 during the movement. When supporting and dumping the aquatic products, it works with the baffle 223b to support and gather the aquatic products, preventing too much aquatic products from falling from the edge of the shovel plate 223 and improving the dumping efficiency.

[0032] In further proposals, such as Figure 6 As shown, the top opening width of the loading container 21 is greater than the width of the shovel plate 223. The traveling mechanism also includes a top cover 23, which covers the exposed position after the shovel plate 223 covers the opening of the loading container 21. The top of the top cover 23 is set with an inclined surface so that the catch can slide into the opening along the inclined surface.

[0033] In further proposals, such as Figure 1 As shown, the traveling mechanism also includes track wheels 24. The traveling mechanism drives the entire device to move through the track wheels 24. The traveling mechanism of the track wheels 24 can adapt to uneven pond ground and improve the traveling mechanism's ability to pass through the edge of the pond.

[0034] In further proposals, such as Figure 7 As shown, the other end of the shipping container 21 is fixedly provided with a support top block 25 for supporting the shovel plate 223. The top of the support top block 25 is provided with a buffer rubber layer 251. The support top block 25 is used to support and buffer the shovel plate 223.

[0035] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
