[0002] Currently, the main methods for controlling golden apple snail eggs include manual removal, chemical control, and biological control. Manual removal is inefficient and labor-intensive, making it difficult to cope with large-scale outbreaks. While chemical agents can quickly kill eggs, they pollute the aquatic environment and can easily lead to drug resistance in golden apple snails. Biological control is slow to take effect and it is difficult to precisely control the killing effect on eggs. Currently, there is no efficient, environmentally friendly, and rapid egg-killing device for golden apple snails, which cannot meet the needs of effective control of this invasive alien species. Utility Model Content

[0003] The present invention aims to provide a golden apple snail egg-killing device to solve the problems of low egg-killing efficiency, easy environmental pollution, slow prevention and control effect, inability to prevent the large-scale reproduction of golden apple snails and the inability of local ecological environment to recover quickly in the existing technology.

[0004] The embodiments of this utility model are implemented as follows:

The end of the connecting frame near the telescopic rod is detachably fixed to one end of the telescopic rod. The end of the connecting frame away from the telescopic rod is provided with a rotatable roller. The outer wall of the roller has a number of protrusions, which are evenly distributed on the outer wall of the roller.

[0007] In use, the connecting frame of the rolling device is connected to one end of the telescopic rod. The length of the telescopic rod is adjusted according to the site conditions. By pushing the roller to roll back and forth, the spikes on the outer wall of the roller crush the eggs of the golden apple snail.

[0008] The golden apple snail egg-killing device disclosed in this embodiment has a rolling device on the telescopic rod, which allows the roller on the rolling device to crush the golden apple snail eggs, thereby achieving the purpose of quickly eliminating the golden apple snail eggs. As a result, the golden apple snail egg-killing device has the beneficial effects of high egg-killing efficiency, no environmental pollution, fast prevention and control effect, and can quickly prevent the large-scale reproduction of golden apple snails and the rapid recovery of the local ecological environment.

[0009] Optionally, a U-shaped bracket is fixedly connected to one end of the connecting frame away from the telescopic rod, and the two ends of the roller are rotatably connected to the two wings of the U-shaped bracket.

[0010] This configuration allows the roller to rotate on the U-shaped support, facilitating the crushing of the golden apple snail eggs by the spikes on the roller.

[0011] Optionally, the two wings of the U-shaped bracket are a first columnar baffle and a second columnar baffle, and the outer sides of the first columnar baffle and the second columnar baffle are respectively provided with a first columnar head and a second columnar head.

[0022] Optionally, a plurality of first holes are provided on one side of the adjusting rod, and the plurality of first holes are evenly distributed along the axial direction of the adjusting rod, and the connecting frame of the rolling device is connected to the inside of the first holes.

[0023] With this configuration, the arrangement of several of the aforementioned first holes facilitates the installation of multiple of the aforementioned roller devices, thereby forming a larger crushing area, which is convenient for the concentrated crushing of a larger area of ​​golden apple snail eggs.

[0024] Optionally: The first hole of the adjusting rod is radially provided with a second hole, the axis of the second hole is perpendicular to the first hole, the second hole is connected to the first hole, a circular hole is provided on the lower outer wall of the connecting bracket, and a screw is threadedly connected to the inside of the second hole, the screw being rotatably abutting against the circular hole of the connecting bracket.

[0026] Optionally: The middle part of the adjusting rod is provided with a connecting block, and the top end of the telescopic rod is threaded to the connecting block.

[0027] With this configuration, by setting the connecting block in the middle of the adjusting rod, the protruding stud at the top of the telescopic rod can be easily connected, and the telescopic rod and the adjusting rod can be kept perpendicular to each other. This makes it easy for workers to grab the telescopic rod and push the adjusting rod forward or backward, causing the rolling device on the adjusting rod to roll back and forth, thereby crushing the golden apple snail eggs.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] Example 1

[0041] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 This embodiment proposes a golden apple snail egg-killing device, including a telescopic rod 1;

[0042] The top end of the telescopic rod 1 is detachably connected to a rolling device 2 for crushing golden apple snail eggs. The rolling device 2 has a connecting frame 3. The end of the connecting frame 3 near the telescopic rod 1 is detachably fixed to one end of the telescopic rod 1. The end of the connecting frame 3 away from the telescopic rod 1 is provided with a rotatable roller 4. The outer wall of the roller 4 has several protrusions 5, which are evenly distributed on the outer wall of the roller 4.

[0043] In use, the connecting frame 3 of the rolling device 2 is connected to one end of the telescopic rod 1. The length of the telescopic rod 1 is adjusted according to the on-site environment. The roller 4 is pushed to roll back and forth, so that the several spikes 5 on the outer wall of the roller 4 crush the eggs of the golden apple snail.

[0044] The golden apple snail egg-killing device disclosed in this embodiment has a rolling device 2 on the telescopic rod 1, which allows the roller 4 on the rolling device 2 to crush the golden apple snail eggs, thereby achieving the purpose of quickly eliminating the golden apple snail eggs. As a result, the golden apple snail egg-killing device has the beneficial effects of high egg-killing efficiency, no environmental pollution, fast prevention and control effect, and can quickly prevent the large-scale reproduction of golden apple snails and the rapid recovery of the local ecological environment.

[0045] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6The end of the connecting frame 3 away from the telescopic rod 1 is fixedly connected to a U-shaped bracket 6. The two ends of the roller 4 are rotatably connected to the two wings of the U-shaped bracket 6, so that the roller 4 can rotate on the U-shaped bracket 6, which makes it easier for the several spikes 5 on the roller 4 to crush the golden apple snail eggs.

[0046] The two wings of the U-shaped support 6 are a first columnar baffle 7 and a second columnar baffle 8. The outer sides of the first columnar baffle 7 and the second columnar baffle 8 are respectively provided with a first columnar head 9 and a second columnar head 10. This arrangement facilitates the connection of the roller 4 on the one hand, and the first columnar head 9 and the second columnar head 10 are convenient for crushing the golden apple snail eggs that cannot be crushed on the other hand.

[0047] The bottom of the connecting frame 3 has an internal threaded hole (not shown in the figure), and the top of the telescopic rod 1 has a protruding stud 11. The protruding stud 11 is threaded onto the internal threaded hole and fits into the inside of the internal threaded hole, making it easy to assemble and disassemble the connecting frame 3 and the telescopic rod 1. This makes it convenient to use and easier to store and transport. At the same time, if a certain part is damaged or worn, the corresponding part can be replaced, which effectively reduces the cost of the golden apple snail egg killer.

[0048] The spikes 5 are staggered and interleaved, which allows them to better crush the golden apple snail eggs and prevents any from being missed.

[0049] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The telescopic rod 1 has a first rod 12, a second rod 13 and a third rod 14, which are connected end to end in sequence;

[0050] The inner bottom of both the first section 12 and the second section 13 is provided with an n-shaped retaining bead spring plate 15. One end of the n-shaped retaining bead spring plate 15 is fixed to the inner bottom of the first section 12 or the second section 13, and the other end of the n-shaped retaining bead spring plate 15 has a spherical protrusion 16. The outer wall of the second section 13 and the third section is provided with several through holes 17 evenly distributed axially. The spherical protrusion 16 can be adjusted to be inserted into any of the through holes 17. When it is necessary to extend the first section 12, the second section 13 and the third section 14 to the required length, the spherical protrusion 16 is pressed down. The protrusion 16 pulls the first section rod 12 or the second section rod 13, causing the spherical protrusion 16 to be embedded in the corresponding through hole 17 under the action of the n-shaped retaining spring plate 15. This fixes the length of the first section rod 12, the second section rod 13, and the third section rod 14. When the telescopic rod 1 needs to be retracted, the spherical protrusion 16 is pressed down, and the first section rod 12, the second section rod 13, and the third section rod 14 can be retracted. This allows the length of the telescopic rod 1 to be changed arbitrarily according to environmental needs, expanding the adaptability of the golden apple snail egg killer.

[0051] The top of the telescopic rod 1 is provided with an adjusting rod 18. The top of the telescopic rod 1 is vertically fixed to the middle of the adjusting rod 18. The rolling device 2 is detachably fixed to the adjusting rod 18. The setting of the adjusting rod 18 facilitates the side-by-side connection of multiple rolling devices 2 to the adjusting rod 18, which increases the crushing area of ​​the golden apple snail eggs and improves the crushing efficiency.

[0052] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A number of first holes 19 are provided on one side of the adjusting rod 18. The number of first holes 19 are evenly distributed along the axial direction of the adjusting rod 18. The connecting frame 3 of the rolling device 2 is connected to the inside of the first holes 19. The arrangement of the number of first holes 19 facilitates the installation of multiple roller 4 devices, thereby forming a larger crushing area, which is convenient for crushing a larger area of ​​golden apple snail eggs.

[0053] The first hole 19 of the adjusting rod 18 has a second hole 20 radially opened. The axis of the second hole 20 is perpendicular to the first hole 19 and the second hole 20 connects to the first hole 19. The lower outer wall of the connecting frame 3 has a round hole 21. A screw (not shown in the figure) is threaded into the second hole 20. The screw can rotatably abut against the round hole 21 of the connecting frame 3. By connecting the screw into the second hole 20, it is easy to lock the connecting frame 3 with the screw, so that the connecting frame 3 is fixed on the adjusting rod 18.

[0054] A connecting block 22 is provided in the middle of the adjusting rod 18. The top end of the telescopic rod 1 is threaded onto the connecting block 22. By providing the connecting block 22 in the middle of the adjusting rod 18, the protruding stud 11 at the top of the telescopic rod 1 can be easily connected, so that the telescopic rod 1 and the adjusting rod 18 remain perpendicular to each other. This makes it easy for workers to grab the telescopic rod 1 and push the adjusting rod 18 forward or backward, causing the rolling device 2 on the adjusting rod 18 to roll back and forth, thereby crushing the golden apple snail eggs.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 In this embodiment, in order to increase the area of ​​crushing golden apple snail eggs, several rolling devices 2 are installed on the adjusting rod 18 to crush the golden apple snail eggs.

[0056] Example 2

[0057] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 Based on Embodiment 1, in this embodiment, the U-shaped bracket 6 of the rolling device 2 has a columnar head on only one side. This makes it easier to reduce the gap between adjacent rolling devices 2 when multiple rolling devices 2 are installed side by side on the adjusting rod 18. When crushing golden apple snail eggs, the smaller gap can ensure the crushing area and achieve the purpose of crushing golden apple snail eggs over a large area, thereby improving the effect.

[0058] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
