Description

Technical Field

[0001] This utility model belongs to the field of biological control, specifically, it relates to an automatic and efficient device for killing golden apple snails. Background Technology

[0002] Golden apple snails have a varied diet, especially aquatic plants. During the rice seedling stage, they will gnaw on the base of the seedling stems, causing the seedlings to die. In the later stages of rice growth, they will climb up the rice stalks and eat the leaves, affecting the rice's photosynthesis and nutrient accumulation. According to statistics, severe golden apple snail infestations can reduce rice yield by 30%-70%.

[0003] To control golden apple snails, farmers need to invest a lot of manpower, material resources, and financial resources. For example, they need to purchase pesticides for chemical control or use manual collection of golden apple snails for physical control. Most existing technologies use capture methods, such as the golden apple snail trapping device with publication number CN216722777U. However, the trapping efficiency is generally not high, and it takes a long time to achieve a certain harvest. At the same time, manual collection is still required at regular intervals. Traditional pesticide spraying has low precision, resulting in large amounts of pesticides used, which increases costs and environmental burden.

[0004] In view of this, this utility model is proposed to provide technical support for the ecological, environmentally friendly, sustainable and efficient control of golden apple snails in rice paddies. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an automatic and efficient device for killing golden apple snails, thus solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0007] An automated and efficient device for eliminating golden apple snails includes: a tracked unmanned vehicle (UAV) that uses a battery pack located inside the vehicle to drive multiple motors that power tracks mounted on wheels, allowing the UAV to move across a paddy field; a camera mounted at the front of the vehicle; a liquid storage tank fixed inside the vehicle; a robotic arm mounted on the top of the vehicle; a high-pressure atomizing nozzle fixed to the free end of the robotic arm; the high-pressure atomizing nozzle spraying pesticides from the liquid storage tank; and a data analysis and transmission module fixed inside the vehicle to control the movement, spraying, and data transmission of the tracked UAV. The camera is connected to the data analysis and transmission module.

[0008] Optionally, a light is installed at the bottom of the camera at the front of the tracked unmanned vehicle. The light is fixed to the vehicle body and is powered by a battery pack.

[0009] Optionally, a protective net is fixed to the lighting fixture.

[0010] Optionally, the tracked unmanned vehicle has a solar panel fixed to the top of its body, which can charge the battery pack.

[0011] Optionally, the interior of the tracked unmanned vehicle is divided into a top and bottom layer by a partition. The battery pack and motor are installed in the bottom layer, while the data analysis and transmission module and the liquid storage tank are installed in the top layer.

[0012] Optionally, the liquid storage tank is installed on the top layer at the bottom of the robotic arm, and the data analysis and transmission module is located at the tail of the top layer.

[0013] Optionally, each data analysis and transmission module is equipped with a power connector and a data transmission interface.

[0014] Optionally, the tracked unmanned vehicle is also equipped with red and blue warning lights at the front.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0016] 1. By combining a camera, a tracked unmanned vehicle, a robotic arm, and a high-pressure atomizing nozzle, pesticides in the storage tank can be precisely sprayed onto the golden apple snails, enabling automatic and efficient elimination of golden apple snails in rice paddies, reducing labor costs, improving operational efficiency, and simultaneously reducing environmental impact through precise pesticide application.

[0017] 2. By installing a light at the bottom of the camera in front of the tracked unmanned vehicle, the light is fixed to the vehicle body and powered by a battery pack, providing stable lighting support for spraying operations when light is insufficient;

[0018] 3. By installing red and blue warning lights on the front of the tracked unmanned vehicle, personnel are alerted to the presence of unmanned vehicles operating nearby, thus avoiding accidents such as collisions due to negligence and ensuring personnel safety.

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] The golden apple snail, native to the Amazon River basin in South America, is the only freshwater snail listed among the world's 100 most invasive alien species. It competes with native species for food resources, squeezing out native snails and causing a reduction in biodiversity. Furthermore, its feeding and excretion activities disturb or alter the composition and structure of aquatic communities, disrupting ecosystem function and stability. The golden apple snail causes direct economic losses to aquatic crops such as rice and water chestnuts, as well as other agricultural crops. It causes damage to rice almost throughout its entire growth cycle, with the seedling to tillering stage being the most damaging. In rice paddy ecosystems, the golden apple snail can feed on approximately 7–24 rice seedlings daily, nibbling at the main tiller and effective tillers, leading to missing seedlings, broken rows, and a reduced number of effective panicles. In severe cases, up to 56% of the plants are affected, resulting in yield reductions of over 50%, or even total crop failure.

[0031] Therefore, in order to control the population of golden apple snails, farmers need to invest a lot of money in purchasing pesticides. For example, the use of chemical agents specifically targeting golden apple snails, such as molluscicides, increases the cost of agricultural production.

[0032] In addition to chemical control, physical control methods are also needed, such as manual collection of golden apple snails. This requires hiring labor and incurs significant human costs. Especially during the peak breeding season for golden apple snails, even more manpower is needed for cleanup.

[0033] However, traditional prevention and control methods are generally inefficient and can easily increase costs and environmental burden.

[0034] Please see Figure 1-4 As shown, this embodiment provides an automatic and efficient device for killing golden apple snails, including: a tracked unmanned vehicle 1, which is driven by a battery pack 3 located in the body 2 of the tracked unmanned vehicle 1, which drives multiple motors 4 to drive the track belts 6 mounted on the wheels 5 to move the tracked unmanned vehicle 1 in the paddy field; a camera 7 is installed at the front of the body 2; a liquid storage tank 8 is fixed inside the body 2; a robotic arm 9 is installed on the top of the body 2; a high-pressure atomizing nozzle 10 is fixed at the free end of the robotic arm 9; the high-pressure atomizing nozzle 10 can spray the pesticide in the liquid storage tank 8; a data analysis and transmission module 11 is fixed inside the body 2 to control the movement, spraying and data transmission of the tracked unmanned vehicle 1; and the camera 7 is connected to the data analysis and transmission module 11.

[0035] Preparation

[0036] Battery charging: Connect the tracked unmanned vehicle 1 to the accompanying charger and ensure that the battery pack 3 is fully charged. When charging, please use the designated charger and follow the safety operating procedures.

[0037] Pesticide preparation: Select the appropriate pesticide (tin triphenylacetate) according to actual needs and slowly pour it into the storage tank 8. Ensure that the pesticide level does not exceed the maximum mark on the storage tank 8, and take personal protective measures to avoid contact with the pesticide on the skin and respiratory tract.

[0038] Environmental Inspection: Before use, inspect the paddy field environment to ensure there are no large obstacles that could affect the normal operation of the tracked unmanned vehicle 1. Also, confirm that the camera 7 has a clear field of view and is unobstructed.

[0039] Operating steps

[0040] Start the equipment: Turn on the power switch of the tracked unmanned vehicle 1. The system will perform a self-test. After the self-test is completed, the data analysis and transmission module 11 will initialize and wait for the operator to input instructions.

[0041] Setting parameters: Through a terminal device (such as a tablet or mobile phone) connected to the data analysis and transmission module 11, parameters such as the driving route, spraying range, and pesticide spraying amount of the tracked unmanned vehicle 1 can be set. These parameters can be flexibly adjusted according to the actual conditions of the paddy field.

[0042] Start the operation: Click the "Start Operation" button on the terminal device, and the tracked unmanned vehicle 1 will begin to travel according to the preset route. The camera 7 collects images of the front in real time and transmits the data to the data analysis and transmission module 11 to ensure the driving safety of the unmanned vehicle. At the same time, the robotic arm 9 will adjust the angle of the atomizing high-pressure nozzle 10 to begin precise pesticide spraying on the golden apple snails in the rice field.

[0043] Operation monitoring: During operation, operators can monitor the unmanned vehicle's driving status, pesticide residue, and other information in real time through terminal devices. If any abnormality is detected, instructions can be immediately sent through the terminal devices to pause or stop the unmanned vehicle's operation.

[0044] Work completed: Once the unmanned vehicle has completed its preset task, it will automatically return to its starting position. The operator can click the "End Work" button on the terminal device to turn off the unmanned vehicle's power switch.

[0045] The aforementioned automated and efficient device for eliminating golden apple snails, through the cooperation of camera 7, tracked unmanned vehicle 1, robotic arm 9, and atomizing high-pressure nozzle 10, can accurately spray pesticides from the storage tank 8 onto the golden apple snails. This enables automated and efficient elimination of golden apple snails in rice paddies, reducing labor costs and improving operational efficiency. At the same time, precise pesticide application reduces environmental impact. This solves the problems of existing technologies, such as generally low trapping efficiency, the need for long placement times to achieve a harvest, and the requirement for regular manual collection; and the low precision of traditional pesticide spraying, which leads to large pesticide usage, increasing costs and environmental burden.

[0046] The tracked unmanned vehicle 1 has a light 12 located at the bottom of the camera 7 in front of the vehicle body 2. The light 12 is fixed to the vehicle body 2 and is powered by the battery pack 3. It can provide stable lighting support for spraying operations when the light is insufficient.

[0047] A protective net 13 is fixed on the lighting lamp 12. The protective net 13 is mainly used to protect the lighting lamp 12 and prevent phototactic mosquitoes from covering the lighting lamp 12 when working at night.

[0048] A solar panel 14 is fixed on the top of the tracked unmanned vehicle 1's body 2. The solar panel 14 can charge the battery pack 3. In a sunny working environment, the solar panel 14 continuously charges the battery pack 3, reducing the dependence on traditional electricity and making the energy source of the tracked unmanned vehicle 1 more sustainable. For example, in a sunny rice paddy area, when the equipment is performing the task of killing golden apple snails, the solar panel 14 can use sunlight to continuously replenish the power of the battery pack 3 and extend the working time of the equipment.

[0049] The tracked unmanned vehicle 1 has its interior divided into a top and bottom layer by a partition 15. The battery pack 3 and motor 4 are installed in the bottom layer, while the data analysis and transmission module 11 and liquid storage tank 8 are installed in the top layer. Installing heavier components like the battery pack 3 and motor 4 in the bottom layer effectively lowers the center of gravity. This significantly enhances the stability of the tracked unmanned vehicle 1 when traversing uneven and complex terrain such as rice paddies. For example, it is less prone to tipping over when encountering ridges or small pits, ensuring safe and continuous operation.

[0050] Placing the data analysis and transmission module 11 and the liquid storage tank 8 on the top layer facilitates inspection, debugging, and maintenance by operators. The data analysis and transmission module 11, as the control core, is positioned on the top layer, allowing technicians to quickly perform parameter settings and troubleshooting. The liquid storage tank 8, also on the top layer, facilitates tasks such as adding pesticides and checking remaining levels. Compared to a distributed layout, this centralized and layered design significantly improves equipment management efficiency.

[0051] The liquid storage tank 8 is installed at the bottom of the top layer of the robotic arm 9, while the data analysis and transmission module 11 is located at the tail of the top layer. Installing the liquid storage tank 8 at the bottom of the top robotic arm 9 minimizes the pesticide delivery path. The shorter delivery distance from the liquid storage tank 8 to the atomizing high-pressure nozzle 10 at the end of the robotic arm 9 reduces pressure loss, ensuring the pesticide is sprayed at a stable pressure and improving the uniformity and stability of the spraying effect. Simultaneously, this compact layout reduces the overall center of gravity shift of the equipment. Since the robotic arm 9 generates forces during operation, the liquid storage tank 8 at its bottom acts as a balancer, making the equipment more stable during pesticide spraying.

[0052] Each data analysis and transmission module 11 is equipped with a power connector 16 and a data transmission interface 17. The data transmission interface 17 allows the data analysis and transmission module 11 to share data with other external devices (such as computers, tablets, etc.) in real time. Operators can connect these devices at the work site to obtain data such as the operating status of the equipment, the rice field images collected by the camera 7, and the distribution of golden apple snails. This allows for rapid adjustment of operational parameters, such as the unmanned vehicle's driving route and the amount of pesticide sprayed, based on the actual situation, thereby improving the accuracy and efficiency of golden apple snail eradication operations. The power interface also facilitates charging of the battery pack 3.

[0053] The tracked unmanned vehicle 1 is also equipped with red and blue warning lights 18 at the front of its body 2. In rice paddy operation scenarios, although the area is relatively open, farmers and agricultural machinery may still be active in the vicinity. The red and blue warning lights 18 emit conspicuous flashing lights, which can effectively attract the attention of people in the vicinity, alerting them to the presence of an unmanned vehicle operating nearby, thus preventing accidents such as collisions due to negligence and ensuring personnel safety. For example, in the early morning or evening when visibility is poor, the warning lights are even more conspicuous, allowing people at a distance to clearly identify the vehicle.

[0054] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
