DETAILED DESCRIPTION
[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the specification of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.
[0026] With reference to Figure 1 , Figure 2 and Figure 5 , the utility model provides an embodiment: a device with sexual lure fukien snails, including shell 1, shell 1 inside fixedly connected with connecting box 5, two rotating parts 11 are rotationally connected in the inner wall bottom of connecting box 5, two rotating parts 11 top all rotationally connect with ratchet 12, two ratchets 12 adjacent side all are provided with pawl 13, two pawls 13 adjacent side all are fixedly connected with tension spring 14, two tension springs 14 adjacent end all are fixedly connected between connecting box 5, shell 1 inside is provided with rotating assembly, and rotating assembly is used to prevent fukien snails from laying eggs.
[0027] Specifically, when the apple snail tries to enter the trapping device, the rotating member 11 is pushed to rotate, and the ratchet wheel 12 at the top of the rotating member 11 is also rotated. At this time, the ratchet wheel 12 overcomes the pulling force of the tension spring 14 to hold the pawl 13, so that the pawl 13 slides on the teeth of the ratchet wheel 12, and the rotating member 11 can rotate smoothly. The apple snail can enter the inside of the device, and when the apple snail enters and tries to return in reverse, the rotating member 11 is reversed to rotate, which makes the ratchet wheel 12 also reverse. At this time, the tension spring 14 holds the pawl 13, and the pawl 13 is clamped into the teeth of the ratchet wheel 12, preventing the ratchet wheel 12 and the rotating member 11 from reversing, thereby preventing the apple snail from returning in reverse, improving the retention ability of the trapping device for the apple snail, and ensuring the trapping results.
[0028] With reference to Figure 3 and Figure 4 , the rotating assembly includes a motor 2, which is fixedly connected between the shell 1, and the output end of the motor 2 is fixedly provided with a rotating rod 9, the surface of the rotating rod 9 is fixedly connected with a scraper 10, the bottom end of the rotating rod 9 penetrates through and extends to the bottom of the shell 1, the bottom end of the rotating rod 9 is fixedly connected with a first gear 15, the front side of the first gear 15 is meshingly connected with a second gear 16, the bottom end of the second gear 16 is fixedly connected with a third gear 17, the bottom of the shell 1 is rotatably connected with a rotating ring 19, the bottom end of the rotating ring 19 is fixedly connected with a gear ring 8, and the outer side of the gear ring 8 is fixedly connected with evenly distributed blocking rods 6.
[0029] Specifically, the motor 2 drives the rotating rod 9 and the scraper 10 to rotate, and when the apple snail is trapped into the device, if the apple snail tries to lay eggs in the device, the rotating scraper 10 will crush the eggs laid by the apple snail, avoiding the successful reproduction of the apple snail in the device and reducing the growth of the population, the bottom end of the rotating rod 9 drives the first gear 15 and the second gear 16 to rotate, so that the third gear 17 at the bottom end of the second gear 16 also rotates, the rotating of the third gear 17 drives the gear ring 8 and the blocking rods 6 connected thereto to rotate intermittently and slowly, and the blocking rods 6 intercept tree leaves, waterweeds and various sundries drifting with the water during the rotating process, preventing them from entering the inside of the trapping device and avoiding the blocking of the trapping channel or the interference of the apple snail entering;
[0030] The rotating speed of the blocking rods 6 is slow and intermittent, which enables the apple snail to have enough time to enter the inside of the device through its own moving ability in the gap of the rotating of the blocking rods 6, and at the same time, the spacing between the blocking rods 6 is reasonably designed, which can effectively intercept common tree leaves, waterweeds and sundries, and also enables the apple snail to pass through smoothly without substantial hindrance to the entering of the apple snail, in addition, the sex attractant in the device has strong attraction to the apple snail, prompting the apple snail to actively find an opportunity to pass through the blocking rods 6 to enter the device, further ensuring that the apple snail can enter smoothly and ensuring the normal operation of the trapping device.
[0031] With reference to Figure 3The two pawls 13 are rotatably connected between the connecting box 5 and the adjacent ratchet wheel 12.
[0032] Specifically, the pawl 13 can rotate flexibly with the connecting box 5 as the supporting point. When the ratchet wheel 12 rotates forward, the pawl 13 smoothly slides on the teeth of the ratchet wheel 12, without affecting the forward rotation of the ratchet wheel 12 driven by the rotating member 11 to allow the apple snail to enter smoothly. When the ratchet wheel 12 attempts to rotate reversely, the closely fitted pawl 13 can quickly engage into the teeth of the ratchet wheel 12, effectively preventing the reverse rotation of the ratchet wheel 12, and further preventing the apple snail from returning reversely.
[0033] Referring to Figure 1 The top of the shell 1 is fixedly connected with a sex pheromone releaser 3, and the surface of the shell 1 is provided with uniformly distributed water outlets 4.
[0034] Specifically, the top of the shell 1 is fixedly connected with the sex pheromone releaser 3, which can stably release the sex pheromone into the device. The sex pheromone releaser 3 can release the sex pheromone of the apple snail, which is placed in the trapping device. The sex pheromone can attract opposite sex apple snails to come. When the apple snail approaches, it will be captured by the trapping device. The surface of the shell 1 is provided with uniformly distributed water outlets 4, which can allow excess water in the device to flow out, prevent water accumulation from affecting the trapping effect, and facilitate water exchange, auxiliary sex pheromone diffusion in water, making the sex pheromone smell spread more widely, attracting more apple snails.
[0035] Referring to Figure 5 The bottom of the shell 1 is fixedly connected with three fixed columns 18, and the bottom ends of the three fixed columns 18 are fixedly connected with a floating disc 7.
[0036] Specifically, the floating disc 7 can make the entire device float on the water surface, ensuring that the device can be stably placed in the water environment, facilitating the trapping of apple snails in different water locations.
[0037] Referring to Figure 5 The third gear 17 is meshingly connected with the gear ring 8, and the top end of the second gear 16 is rotatably connected with the shell 1.
[0038] Specifically, the third gear 17 is provided with a small number of tooth blocks only on the front side, so as to drive the gear ring 8 and the stop rod 6 to rotate slowly and intermittently when the third gear 17 rotates.
[0039] Referring to Figure 2 The lower surface of the scraper 10 is closely fitted with the inner wall of the shell 1.
[0040] Specifically, when the scraper 10 rotates under the driving of the rotating rod 9, it can effectively clean the apple snail eggs attached to the inner wall of the shell 1 and crush them, avoiding the successful reproduction of apple snails in the device.
[0041] Referring to Figure 5The first gear 15, the second gear 16 and the rotating ring 19 are at the same height, and the third gear 17 and the gear ring 8 are at the same height.
[0042] Specifically, the second gear 16 is at a different height from the gear ring 8 and cannot drive the gear ring 8 to rotate, thus enabling the third gear 17 at the bottom to drive the gear ring 8 to rotate intermittently and slowly.
[0043] Reference Figure 1 The top of the outer casing 1 is fixedly connected to the battery compartment 20, which is electrically connected to the motor 2 and the sex attractant releaser 3.
[0044] Specifically, the battery in the battery compartment 20 powers the motor 2 and the sex attractant releaser 3, ensuring that the device can be used in the field.
[0045] Working principle: The user places the device with the sex pheromone attractant into a suitable body of water, turns on the motor 2 to drive the rotating rod 9 to rotate, and the scraper 10 on the surface of the rotating rod 9 rotates accordingly. If a golden apple snail is attracted into the device and attempts to lay eggs, the scraper 10 can crush its eggs and inhibit the golden apple snail's reproduction. The bottom end of the rotating rod 9 drives the first gear 15 to rotate. The first gear 15 interacts with the second gear 16 meshing on the front side, causing the second gear 16 to rotate, which in turn drives the third gear 17 at its bottom end to rotate. The third gear 17, because a few teeth on the front side mesh with the gear ring 8, drives the gear ring 8 and the evenly distributed baffles 6 on the outside to rotate intermittently and slowly. When the baffles 6 rotate, they intercept the debris floating with the water, preventing them from blocking the trapping channel or interfering with the golden apple snail's entry. Because the baffles 6 rotate slowly and intermittently, and the spacing is reasonably designed, the sex pheromone attracts the golden apple snails in the device, allowing them to enter smoothly.
[0046] Meanwhile, the sex pheromone releaser 3 at the top of the shell 1 releases sex pheromones into the interior to create an odor field that attracts golden apple snails. The water outlet 4 on the surface of the shell 1 discharges excess water to assist the diffusion of sex pheromones. The floating plate 7 at the bottom of the device is connected to the shell 1 through three fixed columns 18, so that the device can float stably on the water surface, making it convenient for trapping snails in different waters.
[0047] When the golden apple snail attempts to enter the device, it pushes the rotating part 11 inside the connecting box 5 to rotate. The ratchet 12 overcomes the tension of the tension spring 14 on the pawl 13, and the pawl 13 slides on the teeth of the ratchet 12, allowing the golden apple snail to enter. If it attempts to return in the opposite direction after entering, the rotating part 11 rotates in the opposite direction, and the tension spring 14 pulls the pawl 13 into the teeth of the ratchet 12, preventing it from rotating in the opposite direction and preventing the golden apple snail from escaping.
[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
