Description

TECHNICAL FIELD

[0001] The present application relates to an apple snail trapping device specially used in rice fields. BACKGROUND

[0002] Apple snail is an alien invasive species that is extremely harmful to rice growth. It has strong reproductive capacity, and the diameter of the young snail is only a few millimeters after hatching, and it develops maturely after 3-4 months. Adult apple snails are relatively large, with a shell height of 4-8 cm, a shell diameter of 4-7 cm, a body weight of 100-150 g, and some individuals with a shell diameter of up to 15 cm and a body weight of more than 250 g. Apple snails eat a lot of rice seedlings, young stems and other plants, which seriously affects the yield and quality of rice.

[0003] In the rice-fish mode, the water depth of the rice field needs to be ensured to be not less than 10 cm. In this water level environment, the growth and development of apple snail larvae are more likely to occur, and due to the complexity of the water system in the south, the phenomenon of rice field (larvae)-pond (adult) flooding is more likely to occur, so the prevention and control of apple snails in rice fields can also be regarded as a key link for the killing of apple snails.

[0004] However, the traditional trapping system is often based on the simulation design of loach and yellow eel trapping devices, and uses a single trapping system or a ring-shaped trapping system to trap apple snails. In large rice fields, it is often difficult to apply. Both floating type trapping system and buried type trapping system cannot meet the use of periodic water level in rice field. Therefore, it is urgent to develop a more efficient and more suitable apple snail trapping device for rice field environment. CONTENT OF THE UTILITY MODEL

[0005] The utility model aims at solving the above technical deficiencies, and provides an apple snail trapping device specially used in rice fields. The trapping device is different from the traditional single trapping system or ring-shaped trapping system, and adopts a strip-shaped trapping system more suitable for rice fields. Combined with the design of upper and lower baits, the apple snail trapping device can be better used for trapping apple snails in rice fields. The specific scheme is as follows:

[0006] The apple snail trapping device comprises a long strip-shaped main frame, the main frame is composed of a floating plate and a mounting plate connected in sequence, and an open area is formed between the floating plate and the mounting plate. A plurality of trapping barrels are arranged in the main frame. The device is provided with upper and lower baits arranged in sequence. The upper bait is located in the open area between the floating plate and the mounting plate, and the lower bait is located in the trapping barrel.

[0007] To ensure each trap has independent trapping capability, the trap comprises a cover plate, a central connecting rod, a one-way flap, and a mesh section. The through-hole size of the cover plate matches that of the float plate; the central connecting rod is used to place the upper and lower baits, its top connected to the cover plate and its bottom inserted into the mesh section; the one-way flap allows flow from the outside into the mesh section, and its upper end is connected to the mounting plate; a rigid sealing plate is installed at the bottom of the mesh section. Although this design differs from traditional designs, because the golden apple snail has a hard shell structure, the central connecting rod passing through the one-way flap has minimal impact on the snail's passage and can also, to some extent, prevent mollusks such as loaches from accidentally entering.

[0008] To facilitate bait replacement and improve efficiency, the upper and lower baits can be simultaneously removed and replaced via a cover plate.

[0009] The one-way flap consists of several triangular plates that can be flipped outwards. These triangular plates are arranged in a conical shape and connected to the mounting plate at the top. This structure facilitates the entry of golden apple snails into the trapping tube and prevents them from escaping.

[0010] To facilitate normal use in low water levels, the bottom of the rigid sealing plate can be embedded in soft mud and sand.

[0011] The vertical distance from the lower surface of the float to the lower surface of the rigid sealing plate is 12-20cm, which can adapt to water level changes under different rice-fish integrated farming models.

[0012] There are 8 traps arranged in a horizontal single row to ensure a certain trapping range and efficiency.

[0013] The float is made of lightweight material with a density less than water and insoluble in water, allowing the device to float on the water surface; the trapping tube is made of organic polymer material or metal material to ensure the durability of the device.

[0014] The float and the mounting plate are connected by several connecting columns, which are evenly distributed on both sides of the trapping tube arrangement direction to enhance the stability of the main frame. Beneficial effects

[0015] The use of a strip-shaped trapping system increases the coverage area of ​​the trapping device in rice paddies, attracting more golden apple snails from a wider area compared to traditional single or ring-shaped trapping systems. The design of the upper and lower baits attracts golden apple snails from different levels, improving the success rate of trapping. The upper bait attracts golden apple snails to the device in open areas, while the lower bait further induces them to enter the trapping tube. In actual experiments, after feeding on the upper bait, the golden apple snails usually fall automatically onto the one-way flap of the trapping tube, and are then attracted into the trapping tube by the lower bait inside.

[0016] Compared with traditional small-scale trapping devices, this trapping system can achieve modular and rapid replacement of multiple trapping tubes. The upper and lower baits can be simultaneously pulled out and replaced through the cover plate, making the operation simple and convenient. It is easy to replace the expired bait in a timely manner, ensuring the continuous and efficient operation of the trapping device. Attached Figure Description

[0024] To enhance understanding of this utility model, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model. Example

[0025] Example 1:

[0026] As shown in Figures 1-6, a snail trapping device specifically designed for rice paddies includes a long, narrow main frame. The main frame includes a floating plate 2 and a mounting plate connected vertically, with an open area between the floating plate 2 and the mounting plate.

[0027] The main frame is equipped with multiple trapping tubes. The golden apple snail trapping device is equipped with an upper bait 11 and a lower bait 12 arranged vertically. The upper bait 11 is located in the open area between the float plate 2 and the mounting plate, and the lower bait 12 is located inside the trapping tube.

[0028] The trapping tube includes a cover plate 1, a central connecting rod, a one-way flap, and a mesh section. The cover plate 1 is matched with the through hole size on the float plate 2. When changing the bait, the upper bait 11 and the lower bait 12 can be replaced together by directly removing the cover plate 1 and driving the central connecting rod.

[0029] The intermediate connecting rod is used to set the upper bait 11 and the lower bait 12. The top of the intermediate connecting rod is connected to the cover plate 1, and the bottom of the intermediate connecting rod is inserted into the mesh section. The one-way flap 4 can flow from the outside into the mesh section. The upper end of the one-way flap 4 is connected to the mounting plate. A rigid sealing plate 5 is provided at the bottom of the mesh section. The rigid sealing plate will not deform under the action of daily forces (the maximum force that the golden apple snail may generate).

[0030] Polyethylene foam is used as the material for float 2. The trapping tube is made of polyvinyl chloride. Prepare 8 trapping tubes, as well as corresponding connecting posts 3, cover plates 1, one-way flaps 4, rigid sealing plates 5 and other components.

[0031] First, connect the float plate 2 and the mounting plate using connecting columns 3, ensuring that the connecting columns 3 are evenly distributed on both sides of the trapping cylinder's sorting direction, maintaining a stable distance between the float plate 2 and the mounting plate to form the main frame. Then, connect the upper end of the triangular plate of the one-way flap 4 to the mounting plate to form the one-way flap 4 structure.

[0032] Connect the top of the middle connecting rod to the cover plate 1, and insert the bottom into the mesh section. Place the upper bait 11 and the lower bait 12 on the middle connecting rod, and then align and install the cover plate 1 with the through hole on the float plate 2. Install the rigid sealing plate 5 at the bottom of the mesh section to complete the assembly of a single trap tube.

[0033] Eight assembled trap tubes are installed inside the main frame in a horizontal single-row arrangement.

[0034] Usage scenario 1 (full water level):

[0035] When the paddy field is full of water, or when the water level is higher than the overall trapping system, place the assembled golden apple snail trapping device in a suitable position. Use the float plate 2 to make the entire trapping system float on the water surface, so that both the upper bait 11 and the lower bait 12 are completely submerged below the water surface.

[0036] Some golden apple snails will fall into the trap while feeding on the upper bait 11, while others will be attracted by the lower bait 12 and actively enter the trap. The trap is manually cleaned every once in a while.

[0037] Application Scenario 2 (Low Water Level):

[0038] When the water level in the paddy field is low, place the assembled golden apple snail trapping device in a suitable location, ensuring the bottom of the rigid sealing plate 5 is embedded in the soft mud to guarantee stability. It is also necessary to ensure that both the upper bait 11 and the lower bait 12 are below the water level. Some golden apple snails will fall into the trapping tube while feeding on the upper bait 11, while others will continue to be attracted by the lower bait 12 and actively enter the trapping tube. The trapping tube should be manually cleaned periodically. After cleaning, the height should be readjusted and the device reinstalled.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
