Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of biological invasion, especially to a pomacea canaliculata egg clamp. BACKGROUND

[0002] Pomacea canaliculata is listed as the first batch of invasive species in China, and has strong reproductive capacity. Since pomacea canaliculata eggs can only develop normally in the air, the female snail will leave the water body when laying eggs, and lay eggs on dry objects such as wooden piles, field ridges, stems, etc. 10-20 cm away from the water surface. The whole egg-laying process lasts 1-2 hours. Generally in the water area of parks, paddy fields, etc. Pomacea canaliculata eggs often adhere to hard revetments, landscape stones, wooden piles, stems of emergent plants, and trunks of hygrophytes.

[0003] When cleaning pomacea canaliculata eggs, the eggs are usually knocked off the attachment by artificial long poles. Compared with hard revetments and landscape stones, the stems and leaves of hygrophytes are more fragile as living things. If a long pole is directly used to knock the stems and leaves of emergent plants, irreversible damage will be caused to the plant body. Therefore, a pomacea canaliculata egg clamp is needed to remove pomacea canaliculata eggs under the premise of reducing damage to the plant body, effectively preventing and controlling biological invasion. UTILITY MODEL CONTENT

[0004] An object of the utility model is to provide a pomacea canaliculata egg clamp to clamp pomacea canaliculata eggs from emergent plants, reducing damage to the plant body, especially emergent plants.

[0045] The following describes in detail, with reference to the accompanying drawings, a golden apple snail egg grasper according to an embodiment of the present invention.

[0046] Reference Figures 1-6 The golden apple snail egg grasper includes a rod 1, with mounting blocks 2 and operating handles 3 connected to both ends of the rod 1 along its length.

[0047] Two clamping plates 4 are slidably mounted on the mounting block 2, and the two clamping plates 4 slide toward each other or toward each other. The clamping plate 4 includes a connecting part 41 and a clamping part 42. The connecting part 41 and the clamping part 42 are connected in a T-shape, which increases the contact area between the clamping plate 4 and the golden apple snail eggs. The connecting part 41 is connected to the mounting block 2, and the length direction of the clamping part 42 is perpendicular to the axis of the rod body 1.

[0048] The size of the gripping part 42 is adapted to the overall size of the stacked golden apple snail eggs. The length and width of the gripping part 42 are designed according to the morphological characteristics and size of the stacked golden apple snail eggs. The gripping part 42 can be designed with different sizes according to different morphological characteristics and different sizes of the stacked golden apple snail eggs. In this embodiment, based on the overall size of the stacked golden apple snail eggs encountered in practice, the length of the gripping part 42 is 10cm and the width of the gripping part 42 is 4cm.

[0049] The mounting block 2 has a sliding groove 21 for the connecting part 41 to slide. Limiting blocks 411 are provided on both sides of the connecting part 41 in the width direction. Limiting grooves 211 for the limiting blocks 411 to slide are provided on the inner walls of both sides of the sliding groove 21 in the width direction. Both the limiting grooves 211 and the limiting blocks 411 are dovetail-shaped. Support blocks 412 are also provided on both sides of the connecting part 41 in the width direction. Guide blocks 4121 are fixedly connected to the bottom surface of the support blocks 412. Guide grooves 212 for the guide blocks 4121 to slide are provided on the top surfaces of both sides of the mounting block 2 in the width direction. Both the guide grooves 212 and the guide blocks 4121 are dovetail-shaped. When the clamping plate 4 slides, the limiting blocks 411 slide within the limiting grooves 211, and the support blocks 412 slide within the guide grooves 212, improving the stability of the clamping plate 4's sliding.

[0050] The mounting block 2 is also equipped with a drive component 5, which is used to drive the clamping plate 4 to slide.

[0051] The drive assembly 5 includes a drive motor 51 and a bidirectional lead screw 52. The mounting block 2 has a mounting groove for mounting the drive motor 51. A synchronous gear 53 is connected to the output shaft of the drive motor 51, and a synchronous gear 54 is connected to the bidirectional lead screw 52. The synchronous gear 54 is connected to the middle of the bidirectional lead screw 52 in the axial direction. The synchronous gear 54 and the synchronous gear 53 are connected by a synchronous toothed belt 55 and rotate synchronously. The two ends of the bidirectional lead screw 52 pass through the corresponding connecting parts 41 and are threadedly connected to the corresponding connecting parts 41. The two ends of the bidirectional lead screw 52 are rotatably connected to the mounting block 2.

[0052] The operating handle 3 is equipped with a control component 6 for controlling the start and stop of the motor.

[0053] The control component 6 includes an on button 61, a reset button 62, a pressure sensor 1 63, and a pressure sensor 2 64. All three are electrically connected to the drive motor 51. The on button 61 and reset button 62 are located on the operating grip 3 for easy operation. A mounting hole 1 is provided on the side of the gripping part 42 that is close to each other, penetrating both sides of the gripping part 42 in the thickness direction. The pressure sensor 1 63 is disposed within the mounting hole 1. A mounting hole 2 is provided on the inner wall of the side of the slide groove 21 that is far from each other, penetrating both ends of the slide groove 21 in the length direction. The pressure sensor 2 64 is disposed within the mounting hole 2. In this embodiment, both pressure sensors 1 63 and 2 64 are wireless charging type pressure sensors.

[0054] A rubber pad 7 is provided on the side of the clamping part 42 that is close to each other. The rubber pad 7 abuts against the golden apple snail egg, which increases the friction between the rubber pad 7 and the golden apple snail egg and reduces the possibility of the golden apple snail egg detaching from the clamping plate 4. The golden apple snail egg applies pressure to the rubber pad 7, causing the rubber pad 7 to deform and apply pressure to the pressure sensor 63, enabling the pressure sensor 63 to detect the pressure applied by the golden apple snail egg to the clamping plate 4.

[0055] The start button 61 is used to control the drive motor 51 to start and rotate in the forward direction, so that the two clamping plates 4 slide towards each other. When the clamping plates 4 clamp the golden apple snail eggs, the pressure sensor 63 detects the pressure value applied by the golden apple snail eggs to the clamping plates 4 and sends the pressure value to the control system of the drive motor 51. When the pressure value reaches the set value, the control system of the drive motor 51 controls the drive motor 51 to turn off.

[0056] The reset button 62 is used to control the drive motor 51 to start and rotate in the reverse direction, causing the two clamping plates 4 to slide in a direction away from each other. When the clamping plates 4 move to abut against the inner wall of the slide groove 21, the pressure sensor 64 detects the pressure value applied by the connecting part 41 to the inner wall of the slide groove 21 and sends the pressure value to the control system of the drive motor 51. When the pressure value reaches the set value, the control system of the drive motor 51 controls the drive motor 51 to shut down. The control system of the drive motor 51 is a microcontroller, and the electrical connection between the pressure sensor and the motor is conventional existing technology, so the solution will not be described in detail here.

[0057] The bottom of the operating handle 3 has a receiving chamber 31, which houses a battery 8. The battery 8 supplies power to the drive motor 51, the control system of the drive motor 51, the start button 61, the reset button 62, pressure sensor 1 63, and pressure sensor 2 64. The rod body 1 is hollow inside, and the space inside the rod body 1 forms a wiring channel 32 through which the power supply line passes. The wiring channel 32 is connected to the receiving chamber 31. A cover plate is fixed to the bottom of the operating handle 3 with screws to reduce the possibility of dust entering the receiving chamber 31. The battery can be replaced by removing the cover plate.

[0058] The rod 1 includes a front rod 11 and a rear rod 12. The mounting block 2 is connected to the end of the front rod 11 away from the rear rod 12. The operating handle 3 is connected to the end of the rear rod 12 away from the front rod 11. The front rod 11 and the rear rod 12 are slidably connected. The front rod 11 has a connecting groove 111 for the rear rod 12 to slide. The outer wall of the rear rod 12 is provided with a limiting protrusion 121. The inner wall of the connecting groove 111 has a strip-shaped groove 112 for the limiting protrusion 121 to slide. When the front rod 11 and the rear rod 12 slide, the limiting protrusion 121 slides in the strip-shaped groove 112, which improves the stability of the sliding between the front rod 11 and the rear rod 12.

[0059] The front rod 11 and the rear rod 12 are locked together by the locking assembly 9. The front rod 11 and the rear rod 12 are slidably connected, allowing the length of the rod 1 to extend or retract, thus improving the applicability of the rod 1.

[0060] The locking assembly 9 includes a retaining ring 91 and a locking ring 92. The retaining ring 91 is fixedly sleeved on the end of the front rod 11 near the rear rod 12. The end of the retaining ring 91 near the rear rod 12 has a strip groove 911. Multiple strip grooves 911 are spaced apart along the circumference of the retaining ring 91, so that multiple locking strips 912 are formed at the end of the retaining ring 91 near the rear rod 12. The outer wall of the locking strip 912 forms a mating wedge surface 913. The mating wedge surface 913 is inclined towards the central axis near the front rod 11 along the direction from the front rod 11 to the rear rod 12. The portion of the locking strip 912 with the mating wedge surface 913 extends onto the rear rod 12, and the inner wall of the locking strip 912 abuts against the outer wall of the rear rod 12.

[0061] The locking ring 92 is sleeved on the fixed ring 91. The locking ring 92 has a locking wedge surface 921 at the end near the rear rod 12. The locking wedge surface 921 is interference-fitted with the mating wedge surface 913. The outer peripheral wall of the fixed ring 91 near the front rod 11 is provided with external threads, and the inner peripheral wall of the locking ring 92 near the front rod 11 is provided with internal threads. The locking ring 92 is threadedly connected to the fixed ring 91. When the locking ring 92 is rotated until the locking wedge surface 921 is interference-fitted with the mating wedge surface 913, the locking bar 912 presses against the rear rod 12 to fix the rod body 1 after the length adjustment.

[0062] The implementation principle of the golden apple snail egg-collecting device in this application embodiment is as follows:

[0063] When picking up golden apple snail eggs attached to emergent plants, align the clamping plate 4 with the golden apple snail eggs, so that the golden apple snail eggs are located between the two clamping plates 4. Press the start button 61 to make the drive motor 51 rotate in the forward direction. When the pressure sensor 63 detects that the pressure value applied by the golden apple snail eggs to the clamping plate 4 reaches the set value, the control system of the drive motor 51 controls the drive motor 51 to shut down, and the clamping plate 4 clamps the golden apple snail eggs. Then the operator can remove the golden apple snail eggs through the rod 1, which reduces damage to the plants, especially emergent plants.

[0064] Then press the reset button 62 to make the drive motor 51 rotate in the opposite direction. When the pressure sensor 64 detects that the pressure value applied by the connecting part 41 to the inner wall of the slide groove 21 reaches the set value, the control system of the drive motor 51 controls the drive motor 51 to shut down, so that the clamping plate 4 resets.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
