Description

Technical Field

[0001] This utility model relates to the technical field of agricultural pest capture / killing devices, and in particular to a device for preventing the reproduction of golden apple snails in aquatic organisms, specifically a golden apple snail egg capture device. Background Technology

[0002] Golden apple snails, a typical invasive alien species, have spread rapidly since their introduction to my country, causing harm in multiple areas including ecology, agriculture, and human health. Ecologically, golden apple snails have an extremely high reproductive capacity, laying eggs for 2-3 generations per year, with a single layup producing hundreds to thousands of eggs, and a hatching rate exceeding 80%. Lacking natural predators, they compete with native species for resources by consuming aquatic plants, leading to ecological imbalances and a decline in biodiversity. For example, golden apple snails prey heavily on native snails, causing a sharp decline in their numbers and even triggering eutrophication in some areas. In agriculture, golden apple snails primarily feed on crops such as rice and lotus roots. Especially during the rice seedling stage, a single adult snail with a shell height of 3.5 cm can consume multiple seedlings daily, resulting in yield reductions of 10%-90%, with losses in severely affected areas often exceeding 50%. Furthermore, golden apple snail excrement pollutes water bodies, further exacerbating the deterioration of the crop growing environment. For human health, the golden apple snail is an intermediate host of Angiostrongylus cantonensis. If the parasites in the snail enter the human body through undercooked snail meat, they may cause erythrocytic meningitis or myelitis, which can be fatal in severe cases.

[0003] To control the golden apple snail, current technologies primarily employ multi-dimensional measures to suppress its reproduction and spread. In terms of agricultural control, crop rotation and deep plowing / drying can disrupt its habitat, while clearing silt and weeds from ditches in winter reduces the survival rate of overwintering snails. Installing barrier nets at paddy field inlets effectively prevents the snails from spreading with the water flow. Manual capture utilizes the peak egg-laying period to collect pink egg masses, or combines this with the snails' aggregation characteristics during field drying. Biological control relies mainly on ecological chain regulation; for example, releasing ducks during the rice growing season allows them to prey on juvenile snails, with a density of 15-30 ducks per acre significantly reducing snail population density. Chemical control requires caution; commonly used agents include 10% snail granules and 50% molluscicide ethanolamine salt. Application should be timed to the rice leaf-heart stage or transplanting stage, with two applications spaced apart to control snail infestation. Physical control focuses on disrupting reproductive conditions, such as using bamboo sticks inserted in the field to collect and destroy egg masses, or using flood irrigation to reduce the hatching rate of egg masses. In addition, management measures emphasize systematic joint prevention and control, such as establishing regional prevention and control mechanisms, with the government coordinating special funds and action guidelines, and combining public education to raise awareness of prevention and control.

[0004] In summary, the control of golden apple snails requires a combination of ecological principles and agricultural practices. It involves reducing their population density through the synergy of multiple technologies, while also being mindful of the potential environmental impacts of chemical agents. Biological and physical methods should be prioritized for sustainable management. Utility Model Content

[0005] To address the problem of the rapid and massive reproduction of golden apple snails, this application proposes a physical control method to destroy the eggs of golden apple snails, thereby reducing the initial number of hatching snails, lowering the hatching rate, and preventing the hatching of juvenile snails; specifically, it provides a golden apple snail egg capture device.

[0006] Through analysis and summarization of the living habits of the golden apple snail, it has been found that its egg-laying follows a specific pattern: golden apple snails typically prefer to lay eggs on smooth rods, and they mostly choose dry locations 20-30 cm above the water surface where they spawn. To capture as many golden apple snail eggs as possible and minimize their reproduction, this invention is provided. This invention provides an egg-attaching rod that provides ideal conditions for golden apple snail egg-laying, inducing the snails to lay eggs on the smooth rod. A collection mechanism then collects the eggs attached to the rod, and a crushing mechanism destroys them, thereby preventing the snails from reproducing.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0008] A golden apple snail egg-catching device includes an energy storage mechanism and at least one egg-attaching rod; and a lifting mechanism, a crushing mechanism, and a collecting mechanism, all electrically connected to the energy storage mechanism. The collecting mechanism is driven by the lifting mechanism and moves up and down under the drive of the lifting mechanism to collect the golden apple snail eggs attached to the egg-attaching rod. The crushing mechanism is located at the top of the lifting mechanism. When the collecting mechanism moves to the top of the lifting mechanism, a limit switch is triggered to control the crushing mechanism to crush the golden apple snail eggs located in the collecting mechanism.

[0009] To better collect golden apple snail eggs and prevent them from falling during collection, thus reducing the effective collection rate, this utility model preferably includes a collection mechanism comprising a lifting seat driven and connected to a lifting mechanism and moving up and down along the lifting mechanism, and two half-discs hinged to the lifting seat and symmetrically installed. Each half-disc has a clearance groove at its center to avoid the egg-attaching rod. When the two half-discs are closed, the two clearance grooves on the half-discs correspond to the cross-sectional shape of the egg-attaching rod. The lifting seat is also equipped with an opening / closing drive mechanism to drive the two half-discs to close / open.

[0010] More preferably, the opening and closing drive mechanism includes a third driver, a reducer fixedly mounted on the lifting seat and driven by the third driver, a drive gear on the output shaft of the reducer, a driven gear fixedly mounted on the hinge shaft of any half disc, two driven gears meshing with each other, one of the driven gears meshing with the drive gear.

[0011] This utility model also provides another opening and closing drive mechanism. Preferably, the opening and closing drive mechanism includes at least one third driver. The third driver drives one or two half-discs to be connected via a linkage mechanism. The third driver drives the two half-discs to close / open by forward / reverse rotation.

[0012] In order to fully destroy the golden apple snail eggs and prevent them from hatching, the crushing mechanism preferably includes a bracket fixedly connected to the top of the lifting mechanism, a second driver fixedly mounted on the bracket, a drive shaft and a blade for crushing the golden apple snail eggs sequentially connected to the second driver, and a splash guard installed on the lower surface of the bracket to shield the drive shaft and / or the blade.

[0013] To improve the automation and reliability of this utility model, preferably, the lower surface of the support is also provided with a limit switch for controlling the stop and start of the crushing mechanism and the lifting mechanism.

[0014] To facilitate better collection and repeated use, and to collect golden apple snail eggs in multiple cycles, the lifting mechanism further preferably includes a first driver, a gearbox, a lead screw, and a support arm fixedly installed below the gearbox to limit the sliding trajectory of the lifting seat. The lead screw is arranged parallel to the support arm, and the bottom of the support arm is provided with a spike that facilitates insertion into the muddy field.

[0015] To facilitate the crawling of the golden apple snail, the egg-attaching rod is a smooth rod structure and is fixedly connected to the support arm near the lower part through a connecting bracket.

[0016] To encourage golden apple snails to lay their eggs only on the egg-laying rod and avoid the problem of difficult collection due to eggs laid elsewhere, preferably, the support arm has an umbrella-shaped section near its lower end to prevent the snails from crawling. The cross-sectional area of ​​the umbrella-shaped section is significantly larger than that of the support arm, making it difficult for the snails to climb onto it. Meanwhile, the adjacent egg-laying rod is smoothly designed, further facilitating the snails' crawling and egg-laying, resulting in more concentrated egg production and easier collection and destruction.

[0017] To further broaden the application environment of this utility model, reduce energy consumption, and avoid wiring problems, this utility model also includes a photovoltaic panel, which is electrically connected to the energy storage mechanism.

[0018] Beneficial effects:

[0019] 1. Based on the tendency and characteristics of the golden apple snail in choosing its spawning site, this utility model is specially designed with an egg-attaching rod that meets the ideal spawning environment of the golden apple snail. The collection mechanism can effectively collect all the golden apple snail eggs on the egg-attaching rod by moving from bottom to top, and then use a crushing mechanism to completely destroy them. This can effectively prevent the golden apple snail eggs from hatching and causing the problem of large-scale reproduction that damages aquatic plants and the ecological environment.

[0020] 2. The working mechanism of this utility model can be wired connection and manual centralized control, or it can be powered by a rechargeable battery and automatically controlled by a microcontroller, making it widely applicable; different control methods can be adopted according to different application scenarios.

[0021] 3. This utility model operates on a once-a-day basis, resulting in a very short cumulative working time and low energy consumption throughout the entire golden apple snail egg-laying period. It is highly efficient and thorough in destroying the golden apple snail eggs, and is very effective in preventing the reproduction of golden apple snails. Attached Figure Description

[0034] Example 1:

[0035] This embodiment provides a device for capturing golden apple snail eggs; see the attached instruction manual. Figures 1-3 As shown, it includes an energy storage mechanism 400 and at least one egg-attaching rod 500; and a lifting mechanism 100, a crushing mechanism 200 and a collecting mechanism 300, which are electrically connected to the energy storage mechanism 400 respectively. The collecting mechanism 300 is driven to the lifting mechanism 100 and moves up and down under the drive of the lifting mechanism 100 to collect the golden apple snail eggs attached to the egg-attaching rod 500. The crushing mechanism 200 is located at the top of the lifting mechanism 100. When the collecting mechanism 300 moves to the top of the lifting mechanism 100, it triggers a limit switch 206 to control the crushing mechanism 200 to crush the golden apple snail eggs located in the collecting mechanism 300.

[0036] Brief description of working principle: The energy storage mechanism 400 is used to provide electrical energy and send control electrical signals to the lifting mechanism 100, the crushing mechanism 200, and the collecting mechanism 300. The energy storage mechanism 400 includes a rechargeable battery, as well as circuits and switches for electrical connection with the lifting mechanism 100, the crushing mechanism 200, and the collecting mechanism 300, which act as actuators. Admittedly, the energy storage mechanism 400 in this embodiment can be implemented using existing technology. For example, taking a wired connection and manual control mode as an example, its working principle is as follows:

[0037] The operator controls the working state of any of the following mechanisms by switching the energy storage mechanism 400 on or off with one or more of the lifting mechanism 100, crushing mechanism 200, and collecting mechanism 300 via a control switch. The energy storage mechanism 400 can be replenished via a wired cable or by using an external self-charging mechanism, such as a photovoltaic panel or wind power generator. Since the lifting mechanism 100, crushing mechanism 200, and collecting mechanism 300 operate for a very short time (generally less than one minute) within 24 hours, self-charging is sufficient to meet their power needs. When the energy storage mechanism 400 is in automatic control mode, a microcontroller sends execution commands to the lifting mechanism 100, crushing mechanism 200, and collecting mechanism 300 at set intervals according to a predetermined circuit configuration, controlling the corresponding actuators to operate or remain in standby mode.

[0038] The collection mechanism 300 collects golden apple snail eggs by moving up and down along the egg-attaching rod 500. Different structural settings are adopted depending on the position of the collection mechanism 300 when it is not in operation. However, regardless of the structural settings, as long as it can move along the egg-attaching rod 500, it can scrape off the golden apple snail eggs attached to the egg-attaching rod 500. For example, when the collecting mechanism 300 is in a non-working state and located at the bottom near the mud, its structure can remain unchanged, as long as it is slidably mounted on the lifting mechanism 100. When not in use, the collecting mechanism 300 remains at the bottom near the mud, thus not affecting the crawling of the golden apple snails. When it is necessary to scrape off the eggs attached to the egg-bearing rod 500, the lifting mechanism 100 drives the collecting mechanism 300 to move upward, thereby scraping off and collecting the golden apple snail eggs in the collecting mechanism 300 during the movement, until it moves to the top position of the lifting mechanism 100, so that the collecting mechanism 300 cooperates with the crushing mechanism 200. At this time, the crushing mechanism 200 is activated automatically or manually to crush the golden apple snail eggs in the collecting mechanism 300, thereby preventing the golden apple snail eggs from hatching and reproducing. It is worth noting that, in order to improve collection efficiency and provide more egg-laying carriers for golden apple snails, multiple egg-attaching rods 500 can be set up, for example, two rods. In this case, the collection mechanism 300 will cooperate with the two egg-attaching rods 500 to collect eggs simultaneously.

[0039] Example 2:

[0040] This embodiment further refines the collection mechanism 300 based on Embodiment 1. In this embodiment, to better collect the golden apple snail eggs and prevent them from falling off during the collection process, thus avoiding a reduction in the effective collection rate, please refer to [reference needed]. Figures 2-4 As shown, the collection mechanism 300 in this embodiment includes a lifting seat 301 that is driven and connected to the lifting mechanism 100 and moves up and down along the lifting mechanism 100, and two half-discs 302 that are hinged to the lifting seat 301 and symmetrically installed. Each half-disc 302 has a clearance groove 3021 at its center to avoid the egg-attaching rod 500. When the two half-discs 302 are in the closed state, the two clearance grooves 3021 on the half-discs 302 have through holes that are adapted to the cross-sectional shape of the egg-attaching rod 500. The lifting seat 301 is also equipped with an opening and closing drive mechanism for driving the two half-discs 302 to close / open. It is worth noting that when there are two egg-attaching rods 500, the half-discs 302 are not semicircles, but two interconnected semicircles; if there are three rods, the half-discs 302 are three interconnected semicircles, and so on. Of course, since the lifting mechanism 100 is on one side of the half-plate 302, the number of egg-attaching rods 500 cannot be increased indefinitely; it is best to keep it appropriate.

[0041] Furthermore, the opening and closing drive mechanism includes a third driver 304, a reducer 303 fixedly mounted on the lifting seat 301 and drivenly connected to the third driver 304, a drive gear on the output shaft of the reducer 303, a driven gear fixedly mounted on the hinge shaft of any half disc 302, two driven gears meshing with each other, one of the driven gears meshing with the drive gear.

[0042] Working principle: This embodiment provides a system where, in a non-collecting state, the collecting mechanism 300 is always above the water surface and does not need to be submerged. For example, the collecting mechanism 300 is positioned at the top of the lifting mechanism 100, and the half-disc 302 is either open or closed. When it is necessary to collect golden apple snail eggs, for example, after a 24-hour interval, the third driver 304 transmits the driving force to the driven gear through the reducer 303, thereby opening the half-disc 302. The purpose of opening the half-disc 302 is to avoid contact with the golden apple snail eggs during the descent of the half-disc 302, which would prevent the golden apple snail eggs from being effectively collected into the half-disc 302 and thus causing them to fall into the water, potentially hatching into golden apple snails. This approach does not achieve absolute destruction or prevention of the eggs. The half-disc 302 is opened and moved to the bottom of the lifting mechanism 100, and then closed by the third driver 304. The lifting mechanism 100 then moves the entire collecting mechanism 300 upwards. During this process, all the golden apple snail eggs attached to the egg-laying rod 500 are scraped off and fall into the half-disc 302. This structure ensures that the collecting mechanism 300 is almost never in contact with water, reducing the waterproofing requirements. Because it is not constantly submerged in water, the requirements for rust prevention and corrosion resistance are also lower, resulting in a longer service life. Of course, to further improve automation and intelligence, those skilled in the art can add level sensors, timers, etc., to the single-chip microcomputer control circuit used to control the collecting mechanism 300 and the lifting mechanism 100, based on the embodiment provided, to achieve periodic collection and crushing without human intervention. For example, it can be set to collect once every 24 hours, with the collection time set at 12 noon, when the sunlight is strong and golden apple snails generally do not lay eggs at this time, thus facilitating collection and crushing. Of course, this is only one option; the collection period can be longer or shorter, and the collection frequency can be adjusted according to the actual situation.

[0043] This embodiment also provides another opening and closing drive mechanism. In this embodiment, the opening and closing drive mechanism includes at least one third actuator 304. The third actuator 304 is driven to connect one or two of the half-discs 302 via a linkage mechanism. The third actuator 304 drives the two half-discs 302 to close / open by rotating forward / reverse. As a preferred embodiment, it is best to use an independent third actuator 304 hinged to one of the half-discs 302 via a linkage mechanism. The opening and closing of the two half-discs 302 is achieved by rotating the two third actuators 304 simultaneously. It is worth noting that the specific structure and size of the linkage mechanism can be determined according to the hinge position between the linkage mechanism and the third actuator 304, i.e., the half-disc 302. Those skilled in the art can make flexible choices, which are not listed here.

[0044] Example 3:

[0045] This embodiment is a further refinement based on any of the above embodiments. In order to fully destroy the golden apple snail eggs and eliminate the possibility of hatching, please refer to the appendix of the instruction manual. Figures 1-4 As shown, in this embodiment, the crushing mechanism 200 includes a bracket 201 fixedly connected to the top of the lifting mechanism 100. A second driver 202 is fixedly installed on the bracket 201, a drive shaft 203 and a blade 205 for crushing golden apple snail eggs are sequentially driven and connected to the second driver 202, and a splash guard 204 is installed on the lower surface of the bracket 201 to shield the drive shaft 203 and / or the blade 205.

[0046] To improve the automation and reliability of this utility model, in this embodiment, the lower surface of the bracket 201 is further provided with a limit switch 206 for controlling the stop and start of the crushing mechanism 200 and the lifting mechanism 100. When the collecting mechanism 300 has not reached the top of the lifting mechanism 100 and touched the limit switch 206, the limit switch 206 is disconnected for the crushing mechanism 200, but connected for the lifting mechanism 100. At this time, the lifting mechanism 100 is controlled by the control circuit in the energy storage mechanism 400. When the limit switch 206 is touched and opened by the collecting mechanism 300, the crushing mechanism 200 is energized and begins to work. At this time, the circuit of the lifting mechanism 100 is forcibly physically disconnected, ensuring that the collecting mechanism 300 always maintains the same position as the crushing mechanism 200. (See the appendix of the specification.) Figure 1 As shown in the top-positioned collection mechanism 300, the blade 205 is fully placed in the half-disc 302 of the collection mechanism 300 to crush the collected golden apple snail eggs. It is worth noting that the limit switch 206 can also be used independently as a control switch for starting / stopping the crushing mechanism 200, without needing to be connected to the control circuit of the lifting mechanism 100. This allows for the use of a simpler single-pole single-throw switch, eliminating the need for a single-pole double-throw switch structure.

[0047] To facilitate better collection and repeated use, and to collect golden apple snail eggs in multiple cycles, the lifting mechanism 100 further preferably includes a first driver 101, a gearbox 102, a lead screw 104, and a support arm 103 fixedly installed below the gearbox 102 to limit the sliding trajectory of the lifting seat 301. The lead screw 104 is arranged parallel to the support arm 103, and the bottom of the support arm 103 is provided with a spike 105 that facilitates insertion into the muddy field.

[0048] To facilitate the crawling of the golden apple snail, the egg-attaching rod 500 is a smooth rod structure and is fixedly connected to the support arm 103 near the lower part through the connecting bracket 600.

[0049] To encourage golden apple snails to lay their eggs only on the ovipositor 500, and to avoid the problem of difficulty in collecting eggs laid elsewhere, [the following was done]. Figure 3 As shown in this embodiment, the support arm 103 is provided with an umbrella-shaped part 106 near its lower end to prevent the golden apple snail from crawling. The cross-sectional area of ​​the umbrella-shaped part 106 is significantly larger than that of the support arm 103, making it difficult for the golden apple snail to climb up. Meanwhile, the adjacent egg-laying rod 500 is smoothly designed, which is more conducive to the crawling and egg-laying of the golden apple snail, making the egg-laying of the golden apple snail more concentrated and easier to collect and destroy.

[0050] To further broaden the application environment of this utility model, reduce energy consumption, and avoid wiring problems, this utility model also includes a photovoltaic panel 402, which is electrically connected to the energy storage mechanism 400.

[0051] The above description is merely a preferred embodiment of this application. The main improvement of this utility model lies in the mechanical structure. The execution control and the control circuit used are very mature existing technologies, and those skilled in the art can flexibly select them according to different application needs, which will not be described in detail here. This is not intended to limit this application. For those skilled in the art, this application can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
