Description

TECHNICAL FIELD

[0001] The utility model relates to ecological environment protection technical field, concretely relates to a device of catching apple snail. BACKGROUND

[0002] As an alien invasive species, apple snail poses a serious threat to China's aquatic ecosystems and agricultural production. Its strong reproductive capacity and extensive diet enable apple snail to spread rapidly and cause damage to the environment in a short period of time. Therefore, the development of an effective apple snail trapping device becomes an important means of preventing and controlling this pest.

[0003] The common apple snail trapping device usually has a box body and a cover body that can be disassembled and installed, which serves as a collection assembly for collecting and trapping apple snails. Based on this, since apple snails like to adsorb and climb the stems and leaves of aquatic plants and stone walls, a rod is designed to simulate the stems and leaves of aquatic plants and stone walls to trap apple snails.

[0004] However, the surface area of the rod is limited, although it can attract some apple snails by taking advantage of their preference for adsorption. The capacity and potential collection capacity of the box body as a collection assembly far exceed the number of apple snails that can be adsorbed by the rod alone. Therefore, in order to make full use of the collection advantage of the box body and improve the trapping efficiency, it is necessary to propose a device for trapping apple snails that can automatically empty the apple snails on the rod and reduce manual intervention in collection. SUMMARY

[0005] To solve the above problems, the utility model provides a device for trapping apple snails, which traps apple snails climbing the threaded rod and assists the intelligent control of the controller through the cooperation of the threaded rod and the box body, efficiently traps, collects and processes apple snails to reduce their threat to aquatic ecosystems and agricultural production.

[0006] In order to achieve the above purpose, the technical scheme of the utility model is as follows: a device for trapping apple snails, comprising a collection box, the collection box comprising a box body and a box bottom, the box body and the box bottom being detachably connected, the box body top wall being provided with a threaded hole, the box bottom being provided with an inlet screw port, the inlet screw port being provided with a blocking assembly for blocking apple snails from climbing out of the inlet screw port;

[0007] A threaded rod is threadedly connected in the threaded hole, a sleeve fixedly connected to the top wall in the box body is sleeved outside the threaded hole, a bearing plate is provided below the box bottom, a limiting assembly for limiting the rotation of the box body is provided on the outer wall of the box body, a transmission assembly is provided at the bottom end of the threaded rod and located on the surface of the bearing plate, the transmission assembly is used to drive the rotation of the threaded rod, a driving assembly is fixedly connected to the bearing plate and used to drive the rotation of the transmission assembly, and the driving assembly is signal connected with a controller.

[0008] The technical principle of the above scheme is as follows: the threaded hole opened through the top wall of the box body cooperates with the threaded rod to realize the up-down movement of the box body, the apple snail enters the box body through the screw inlet, and when the box body cooperates with the threaded rod to descend, the sleeve can scrape the apple snail on the threaded rod, the threaded rod is driven to rotate through the cooperation of the driving assembly and the transmission assembly, and the up-down movement of the box body is realized.

[0009] The above scheme has the following beneficial effects:

[0010] 1. In the scheme, the cooperation of the threaded rod and the threaded hole realizes the up-down displacement of the box body under the limiting of the limiting assembly and the driving of the driving assembly, on the one hand, the box body is raised to provide a gap for the apple snail to climb in through the screw inlet, and on the other hand, the box body is lowered to scrape the apple snail on the threaded rod, realizing the automatic trapping and collection of the apple snail, reducing the frequency and difficulty of manual intervention, and improving the collection efficiency.

[0011] 2. In the scheme, the design of the limiting assembly ensures the stability of the box body during the up-down movement, reducing the risk of shaking and turning over during the collection or cleaning process caused by the transmission rotation of the box body.

[0012] 3. In the scheme, the design of the blocking assembly enables the apple snail to smoothly enter the box body but is difficult to climb out, reducing the probability of climbing out after trapping and improving the efficiency of the device in trapping the apple snail.

[0013] Further, the blocking assembly comprises a fixed ring fixedly connected to the edge of the screw inlet, a plurality of elastic blocking pieces are hingedly connected to the inner wall of the fixed ring along the circumference thereof, a torsional spring is arranged at the hinge connection between the fixed ring and the blocking piece, and the plurality of blocking pieces are combined to form a conical whole with a tapered tip facing the inside of the box body.

[0014] Beneficial effect: the design of the hinged connection of the blocking piece through the fixed ring enables the blocking piece to swing flexibly, which can block the apple snail from climbing out without causing excessive resistance to the entering apple snail. Since the blocking piece forms a conical whole inward, when the apple snail tries to climb out of the screw inlet, it will be hindered by the blocking piece, increasing the difficulty of climbing out, thereby effectively limiting the apple snail in the collection box.

[0015] Further, the limiting assembly comprises a plurality of sleeve rings fixedly connected to the outer side wall of the box body, a plurality of slide rods are fixedly connected to the top of the bearing plate, and the sleeve rings are sleeved on the slide rods and are in sliding cooperation with the slide rods.

[0016] Beneficial effects: the sliding fit structure of the sleeve ring and the slide rod can effectively limit the movement of the box body in other directions except the vertical direction, ensuring that the box body can maintain stable up and down movement when the threaded rod rotates, reducing unnecessary shaking or tilting, in addition, the user can easily adjust the height of the box body to adapt to different capture environments and needs, improving the practicality and adaptability of the device.

[0017] Further, the driving assembly comprises a driving box, a servo motor is fixedly connected in the driving box, a first gear is coaxially fixedly connected to the output shaft of the servo motor, and the signal input end of the servo motor is signal connected with the output end of the controller.

[0018] Beneficial effects: through the signal connection of the servo motor and the controller, the automation control of the device is realized, the user only needs to send instructions through the controller, and the servo motor can start, run and stop according to the preset program without manual operation, improving the convenience and use efficiency of the device, in addition, the servo motor output shaft is coaxially fixedly connected with the first gear, which ensures the accurate transmission of power, and the high-precision rotation of the servo motor can be accurately converted into the rotation of the first gear, which is conducive to the subsequent driving of the threaded rod through the transmission assembly, ensuring the stability and reliability of the device in the process of capturing the Pomacea canaliculata.

[0019] Further, the transmission assembly comprises a second gear fixedly connected to the bottom end of the threaded rod, a rotating drum fixedly connected to the bottom end of the second gear, and the rotating drum is rotatably connected to the bearing plate.

[0020] Beneficial effects: when the servo motor starts to rotate, the servo motor drives the first gear to rotate, and the second gear rotates in the opposite direction under the meshing of the first gear. Since the second gear is fixedly connected to the bottom of the threaded rod, the threaded rod will rotate with the second gear. The rotating drum is rotatably connected to the bearing plate, and the rotating drum plays a fixing role. Through the meshing of the second gear and the first gear, the rotating power of the servo motor is effectively transmitted to the threaded rod, so that the threaded rod can rotate in a predetermined direction and speed, thereby realizing the up and down movement of the box body. In addition, the rotating drum fixedly connected to the bottom end of the second gear is rotatably connected to the bearing plate, which ensures that the second gear can remain stable during power transmission. The rotating connection of the rotating drum reduces friction and resistance, making power transmission smoother and more efficient.

[0021] Further, the surface of the threaded rod is sprayed with an attractant.

[0022] Beneficial effects: Because the threaded rod is exposed outside the box body, compared with directly spraying the attractant in the box, spraying on the surface of the threaded rod can more effectively trap apple snails, when the apple snails are attracted by the attractant and contact the threaded rod, they may try to climb or adsorb on the threaded rod, and then climb into the collection box, this trapping design can significantly increase the probability of trapping apple snails, which not only helps to reduce the time and effort of manually searching and trapping apple snails, but also improves the overall efficiency of trapping operation.

[0023] Further, the load-bearing plate is fixedly connected with a plurality of fixed pieces at the bottom, and the fixed pieces are in 'L' shape structure.

[0024] Beneficial effects: In outdoor use environment, especially in rivers, lakes and other water areas, the existence of rapids below the water surface may cause certain impact on the device, and the reinforcement design of the 'L' shaped fixed piece can effectively improve the resistance of the device to these external factors, and reduce the risk of damage or failure of the device caused by environmental factors.

[0025] Further, the top end of the threaded rod is fixedly connected with a height limiting block, and the cross-sectional area of the height limiting block is larger than that of the threaded rod.

[0026] Beneficial effects: The design of the height limiting block can limit the maximum height of the box body rising through the threaded rod, prevent the box body from falling off or being unstable due to excessive rising, and ensure the safety and stability of the device during use.
