Description

Technical Field

[0001] This utility model relates to a trap, and more particularly to a golden apple snail trap. Background Technology

[0002] Golden apple snails are characterized by their high reproductive rate, wide diet, and strong adaptability. They have a large appetite and primarily damage the seedlings or young leaves of crops such as rice, lotus root, water chestnut, water caltrop, and arrowhead, causing leaf notches or even biting off the plants, leading to severe seedling loss and disrupted rows, thus affecting food security and the safety of other aquatic crops. Large-scale reproduction of golden apple snails also impacts the biodiversity of local aquatic environments. Furthermore, because they often lay their eggs (pinkish egg masses) on river piers, pond walls, emergent plant stems, and the base of trees along lake edges, they negatively affect the human environment and urban landscape.

[0003] In agricultural production, the control of golden apple snails follows the principle of "prevention first, comprehensive control," and mainly includes the following methods:

[0004] Firstly, agricultural control: This mainly includes crop rotation and the clearing of farmland irrigation ditches. However, due to local planting habits and actual environment, the promotion of these methods nationwide has been limited.

[0005] Secondly, physical control methods are used: The irrigation inlets and surrounding ridges of paddy fields are areas where golden apple snails congregate and cause significant damage. Protective nets are installed at key ditches or irrigation inlets to prevent adult snails from entering the crop planting area. However, these nets are often clogged by plant branches, leaves, or other debris, requiring additional manpower for timely cleaning, which is not widely accepted in production. In addition, some areas have tried manual harvesting of snails or removal of egg masses in the fields (or waterways), but this is inefficient and labor-intensive.

[0006] Third, biological control can be adopted in conjunction with farming practices: this includes raising ducklings in rice paddies; raising crayfish and soft-shelled turtles in lotus root and water chestnut fields; and raising ducks and raising grass carp, black carp, and common carp in water systems such as lakes, rivers, ditches, and ponds. These methods require high management skills from farmers and farmers, are costly, and need to conform to local production and living habits.

[0007] Fourth, chemical control is carried out, which generally involves the application of molluscicides such as molluscicides, abamectin, and metaldehyde. However, these agents are toxic to aquatic animals and can only be used in relatively enclosed water environments. Utility Model Content

[0008] Purpose of the utility model: The purpose of this utility model is to propose a golden apple snail trap that can greatly control the population of golden apple snails while being environmentally friendly and requiring low manpower and management costs.

[0009] Technical Solution: This utility model includes a trapping mechanism. A liquid tank is located below the trapping mechanism, and a photovoltaic panel is installed on top of the trapping mechanism. The trapping mechanism includes a base plate and a lower frame. Multiple uprights connect the base plate and the lower frame. An action control circuit and a photovoltaic power controller are installed on the surface of the base plate. A gear transmission mechanism is installed below the base plate, comprising multiple gears. The output shaft of each gear is rotatably connected to a rotating blade. The rotating blade is located above the lower frame. A screw is also provided between the base plate and the lower frame, with a snail-sweeping disc connected to the screw. One end of the snail-sweeping disc is slidably connected to an upright. The screw and the snail-sweeping disc are located within the area enclosed by multiple rotating blades.

[0010] One end of the screw-sweeping disc is slidably connected to the upright via a roller, and the screw-sweeping disc is driven to move up and down by a screw mechanism.

[0011] The base plate has multiple rods on top, and photovoltaic panels are installed on the top of these rods. During the day, the direct current generated by the solar photovoltaic panels charges the lithium battery.

[0012] The top end of the output shaft of the gear is fixed to the base plate, and the gear drives the rotating blade to rotate.

[0013] The liquid medicine tank is installed on a base, and multiple legs are installed at the bottom of the base. The legs can be inserted into the mud of the paddy field to prevent the trap from being washed away by the water flow.

[0014] The bottom of the lower frame is connected to the medicine tank by multiple locking pins.

[0015] The top of the screw is mounted on the base plate, and the screw-sweeping disc moves up and down through the screw transmission mechanism.

[0016] The trapping mechanism is covered to protect the motion control circuit and transmission mechanism from rain.

[0017] Beneficial effects: This utility model uses gears to drive the rotating page to rotate at regular intervals, turning the page with golden apple snails crawling on it to the inside so that the snail-sweeping disc can clean it, and then sweeping the snails crawling on the rotating page into the medicine tank. This greatly controls the population of golden apple snails, is environmentally friendly, and requires low manpower and management costs. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings.

[0024] like Figures 1-5 As shown, the golden apple snail trap in this embodiment includes a base 6, which is made of solid wood and serves as the base of the trap. Bait can be placed inside the base 6 to increase the trapping probability. A liquid medicine tank 11 is fixed to the top of the base 6, and multiple legs 7 are installed at the bottom. The legs 7 are made of stainless steel and connected to the base 6 with screws. Four stainless steel legs can be inserted into the mud of the paddy field to prevent the trap from being washed away by the water flow. The liquid medicine tank 11 contains molluscicide; to prevent leakage and environmental pollution, the liquid medicine tank 11 is made of stainless steel.

[0025] A trapping mechanism is installed on top of the liquid medicine tank 11, and a photovoltaic panel 1 is installed on top of the trapping mechanism. Figure 5 As shown, the trapping mechanism includes a base plate 16 and a lower frame 12. Multiple uprights 14 connect the base plate 16 and the lower frame 12. Multiple rods are mounted on the top of the base plate 16, and a photovoltaic panel 1 (a solar photovoltaic panel) is installed on the top of these rods. An action control circuit 3 and a photovoltaic power controller 2 are mounted on the surface of the base plate 16. A gear transmission mechanism 8 is installed below the base plate. In this embodiment, the gear transmission mechanism 8 includes four gears. One end of each gear output shaft is fixed to the base plate 16, and the other end is connected to a rotating leaf 10. The gears drive the rotating leaf 10 to rotate periodically, turning the page with golden apple snails crawling on its exterior to the interior, allowing the snail-sweeping disc 9 to clean it. The rotating leaf 10 is located above the lower frame 12, and the bottom of the lower frame 12 is connected to the liquid tank 11 via multiple locking pins 5.

[0026] A screw 13 is also provided between the base plate 16 and the lower frame 12. The top of the screw 13 is installed on the base plate 16. A screw-sweeping disc 9 is connected to the screw 16. One end of the screw-sweeping disc 9 is slidably connected to the upright 14 through a roller 15. The screw 13 and the screw-sweeping disc 9 are located in the area surrounded by multiple rotating pages 10, thereby sweeping the screws climbing on the rotating pages 10 into the medicine tank 11.

[0027] The trapping mechanism is equipped with a cover 4, which is made of plastic, aluminum alloy or stainless steel plate to protect the action control circuit 3 and the transmission mechanism from being wetted by rain.

[0028] Under the control of the photovoltaic power controller 2, the DC power generated by the solar photovoltaic panel charges the lithium battery during the day. At this time, the snail trapping mechanism is powered off and does not work. At night, the photovoltaic power controller 2 automatically switches to the snail trapping mode. The snail extermination control circuit can also operate normally during thunderstorms at night.

[0029] The working process of this golden apple snail trap is as follows:

[0030] Insert the snail trap into the paddy field, ensuring the water level is 4-5 cm below the locking pin hole. Place the bait in the base plate and turn on the power switch. During the day, the photovoltaic power controller automatically cuts off the power supply to the snail-catching mechanism, and turns it back on at night. After the snail-catching mechanism is powered on, the control circuit initiates a self-test. Once the self-test is complete, the snail-catching mechanism begins operation. Every so often, the rotating motor automatically starts, rotating the four rotating blades 180 degrees. The blades with snails on the outside rotate inward, at which point the snail-sweeping disc motor automatically starts, rotating the screw and causing the snail-sweeping disc to sweep the rotating blades from top to bottom, sweeping the snails into the chemical solution tank. After the snail-sweeping disc descends to the set minimum point, it automatically rises back to its initial position and stops. This process repeats until dawn. After dawn, the photovoltaic power controller automatically cuts off the power supply to the snail-catching mechanism and connects the solar photovoltaic panels to charge the storage battery.

[0031] The golden apple snail trap circuit consists of a solar photovoltaic panel, a photovoltaic power controller, a lithium battery, and a trap control circuit. During the day, the solar photovoltaic panel automatically charges the lithium battery, and at night it automatically switches to trapping mode.

[0032] Table 1 Component Status Table During Operation

[0033]

[0034] Note: "○" indicates that the connection is on, and "×" indicates that the connection is off.

[0035] The circuit works as follows:

[0036] Before the golden apple snail trap circuit can operate normally, the initial state must be such that page 10 is parallel to the lower frame 12 and the snail-sweeping disc 9 is in the highest position. If it is not in this state, the control circuit will automatically run to this state after power-on.

[0037] The circuit operates as follows when the initial state is met:

[0038] The status of each component during circuit operation can be found in the previous table and the "Circuit Wiring Diagram". The operating process is as follows:

[0039] 1) When the photovoltaic power controller detects that the ambient light has reached the set value, it supplies power to the line. Since all position switches are in the initial state, magnetic position switches 1XK and 3XK are turned on, ZJ2 and ZJ4 are energized and closed, 2XK and ZJ3 are disconnected, and only one path of ZJ4-1, ZJ2-1, SJ1, C2-3 and C3-3 is turned on. The power-off delay time relay SJ1 is energized and SJ1-1 is immediately closed.

[0040] 2) When SJ1-1 is engaged, the energized delay-type time relay SJ2 is energized and the timing begins; SJ2-1 closes after a delay.

[0041] 3) When SJ2-1 reaches its set time (15-30 minutes), the page turning motor control relay C1 is energized and C1-1 is engaged, the D1 motor starts, and at the same time C1-2 is disengaged to interlock the lifting motor control circuit to prevent malfunction. C1-3 is activated, the intermediate relay ZJ1 is energized and engaged, ZJ1-1 is activated, and the motor descent control contactor C2 is in standby mode.

[0042] 4) When the page turning motor D1 starts, the four pages rotate simultaneously. The page turning magnetic particles gradually move away from 1XK. The position switch 1XK is reset and disconnected. ZJ2 is de-energized, ZJ2-1 is disconnected, and ZJ2-2 is connected.

[0043] 5) When ZJ2-1 disconnects, SJ1 loses power, SJ1-1 starts to disconnect after a delay (set time 0.5-1.5), and SJ2 continues to engage;

[0044] 6) Before ZJ2-2 is turned on, SJ2-1 is still in the closed state. When the delay time of SJ1-1 is up, SJ2 is de-energized and immediately opens. Due to the connection of ZJ2-2, C1 remains energized, and the page can continue to rotate.

[0045] 7) When the page is rotated to 180 degrees, the magnetic particle approaches the position switch 1XK. 1XK is activated and ZJ2 is energized and attracted, ZJ2-2 is deactivated, and ZJ2-1 is activated.

[0046] 8) When ZJ2-2 is disconnected, C1 is de-energized, C1-1 is disconnected, and the page turning motor D1 stops rotating; C1-2 is reset and connected. Since ZJ1-1 is already connected, C2 is energized, C2-1 / 2 is engaged, the lifting motor D2 starts rotating forward, the swivel disc descends, and C2-3 and C2-4 are disconnected to prevent the page turning circuit and the lifting circuit from malfunctioning, respectively.

[0047] 9) When the swivel disc descends and leaves the highest position, switch 3XK is reset and disconnected, ZJ4 is de-energized, ZJ4-1 disconnects the page-turning circuit to prevent the page-turning circuit from malfunctioning; ZJ4-2 normally closed contact is reset and closed, and since C2-4 is already disconnected, C3 cannot be energized;

[0048] 10) When the sweeping disc descends to the lowest position, the proximity switch 2XK is activated, ZJ3 is energized, the normally closed contact of ZJ3 opens, C2 is de-energized, the C2-1 / 2 contact opens, the D2 motor is de-energized and stops, and the sweeping disc stops descending.

[0049] 11) When C2 is de-energized, C2-3 and C2-4 are reset and connected. Since ZJ4-1 is already disconnected, although C2-3 is connected, the page-turning circuit is still de-energized. Since ZJ4-2 and C1-2 are already connected, C2-4 is reset and connected, and C3 is immediately energized and engaged. C3-1 and C3-2 are engaged, and C3-2 and C3-3 are opened.

[0050] 12) When C3-1 and C3-2 are engaged, the lifting motor D2 reverses and the sweeping disc rises; when C3-2 and C3-3 are disengaged, the rotation control circuit and the descent circuit are disconnected respectively to prevent malfunction.

[0051] 13) When the swivel disc rises to its highest point, the proximity switch 3XK is activated, ZJ4 is energized, ZJ4-1 is connected and ZJ4-2 is disconnected;

[0052] 14) When ZJ4-2 is disconnected and C3 loses power, C3-1 / 2 is disconnected, motor D2 stops, and the swivel disc stops at its highest point;

[0053] 15) When ZJ4-1 is turned on, the rotation control circuit is re-energized, and the circuit repeats the control process after 1).

[0054] When the ambient light reaches the illuminance set by the photovoltaic power controller, the circuit stops working and switches to charging mode.

[0055] The circuit operates as follows when the initial state is not met:

[0056] 1) Page transitions are not parallel to the bottom border, and the scroll wheel is at its highest position:

[0057] At this time, the magnetic particle on the page turner fails to engage contact 1XK, ZJ2 cannot be energized, ZJ2-1 resets and separates, and SJ1 is de-energized and does not engage. However, ZJ2-2 is turned on at this time, and power is supplied to C1 through the circuit of ZJ4-1, ZJ2-2, C1, C2-3, and C3-3. C1-1 engages, the page turner motor D1 starts, and the page turner rotates. When the magnetic particle of the page turner approaches the position switch 1XK, 1XK is turned on, ZJ2 is energized and engages, ZJ2-2 is disconnected, C1 is de-energized, D1 stops, and the page turner stops at the required initial position. At the same time, ZJ2-1 is turned on, SJ1 is re-energized, and the control circuit returns to normal operation.

[0058] 2) Page transitions are not parallel to the bottom border, and the scroll wheel is in the middle position:

[0059] At this time, none of the three position switches are engaged, and ZJ2 to ZJ4 are not energized. All contacts in the circuit diagram are in their original state. Only ZJ4-2, C3, C2-4, and C1-2 are connected in the circuit. Therefore, C3 is energized and engaged, C3-1 and C3-2 are connected, D2 is energized and reverses, and the swivel disc rises to its highest point, approaching 3XK and engaging. At this time, ZJ4 is also energized and engaged, ZJ4-2 is disengaged, C3 is de-energized, and D2 stops. At this time, ZJ4-1 is closed. Since the page rotation position switch 1XK is not engaged, ZJ2-2 is in its original engaged state. C1 is energized and starts, and the page rotation motor drives the page to rotate until it is parallel to the lower frame and stops when it approaches the 1XK action. At this time, the circuit returns to normal operation.

[0060] 3) Page transitions are not parallel to the bottom border, and the scroll wheel is at its lowest position:

[0061] At this time, the 2XK position switch is turned on, and the others are turned off. As can be seen from the circuit diagram, the entire circuit is basically the same as in case b, except that only C3 is energized and engaged, and the circuit automatically runs to the normal operating state according to case b.

[0062] 4) The page transition is parallel to the bottom frame, and the scroll wheel is in the middle position:

[0063] At this time, although the page rotation position switch 1XK is engaged, the position switch on the cleaning disc is disengaged, ZJ4 is de-energized and released, ZJ4-1 is disengaged, the page rotation control circuit and the descent circuit are de-energized and do not work, ZJ4-2 is turned on, the rising circuit is energized and C3 is engaged, the cleaning disc rises, and when it rises to the highest point, 3XK is turned on and ZJ4 is engaged, and the circuit returns to the initial working state.

[0064] 5) The page transition is parallel to the bottom frame, and the scroll wheel is at its lowest position:

[0065] At this time, 1XK and 3XK are disconnected, that is, intermediate relays ZJ2 and ZJ4 are released, and their contacts are in the original state. ZJ4-1 disconnects the page rotation circuit, ZJ4-2 connects the rising circuit, C3 is energized, the cleaning disc automatically rises to the highest point, and the circuit returns to the initial working state.
