A device for catching eels in rice paddy farming

Abstract

This utility model discloses a catching device for rice paddy eel farming, comprising: a catching cage, multiple bait placement devices detachably connected inside the catching cage, multiple conical cage openings on the side surface of the catching cage, and a conical mesh tube fixedly connected to the inner surface of the catching cage. Each of the multiple conical cage openings is connected to the conical mesh tube, and a conical flexible tube is connected to the inner wall of each of the multiple conical cage openings and one side of the conical mesh tube. Through these components and the multiple conical cage openings, the device mimics the "cave environment" naturally inhabited by the eel, distracting it and increasing its entry probability. After the eel enters through the cage opening, the conical flexible tube collapses due to its soft nature, preventing the other end from forming a regular channel, thus preventing the eel from escaping. The conical flexible tubes on the conical cage openings, in conjunction with the conical flexible tubes on the conical mesh tube, form a "dual-entry structure," further confusing the eel, significantly reducing eel escape, and increasing the catch rate per capture.

Description

Technical Field

[0001] This utility model relates to the field of eel farming technology, and in particular to a catching device for rice paddy eel farming. Background Technology

[0002] The rice paddy eel catching device is a specialized tool for efficiently catching eels in rice paddy farming environments.

[0003] Traditional eel traps typically have only a single, large, cone-shaped entrance. This simple structure and limited functionality make it difficult to adapt to the eel's burrowing and wary habits. Due to the large entrance and simple structure, eels are easily alerted and have a low willingness to enter, resulting in low capture efficiency. At the same time, a single opening cannot form an effective one-way escape prevention structure, allowing eels to easily return and escape, resulting in a low capture success rate. Utility Model Content

[0004] The purpose of this utility model is to solve at least one of the technical problems existing in the prior art, and to provide a catching device for rice paddy eel farming, which solves the problems of low entry rate and high escape rate caused by the simple structure of existing catching devices, which are easily detected by eels, and the lack of one-way escape channels.

[0005] This utility model also provides a catching device for rice paddy eel farming, comprising: a catching cage, wherein multiple bait placement devices are detachably connected inside the catching cage, multiple conical cage openings are provided on the side surface of the catching cage, and a conical mesh tube is fixedly connected to the inner surface of the catching cage, wherein multiple conical cage openings are all connected to the conical mesh tube, and a conical flexible tube is connected to one side of the inner wall of multiple conical cage openings and the conical mesh tube.

[0006] According to the present invention, a catching device for rice paddy eel farming is provided, wherein the bait placement device includes: a bait cage, an insertion hole, and a sealing plug. The insertion hole is disposed on the catching cage, the bait cage is threadedly connected to the inner wall of the catching cage, and the sealing plug is threadedly connected to the inlet of the bait cage.

[0007] According to the present invention, a catching device for rice paddy eel farming is provided on the catching cage, and a cover plate is movably connected to the front surface of the catching cage.

[0008] According to the present invention, a catching device for rice paddy eel farming is provided, wherein both the cage door and the cover plate are provided with screw holes, and the inner wall of the screw holes is threaded with a fixing bolt.

[0009] Beneficial effects:

[0010] This technical solution for catching eels in rice paddy farming utilizes a trapping device with multiple small conical openings, mimicking the eels' natural burrowing habits. This design distracts the eels, increasing their chances of entering. The conical structure has a narrow entrance and a wide interior, making it easy for eels to enter but difficult for them to escape directly. After entering the trap, the flexible conical tube collapses due to its softness, preventing the other end from forming a regular passage and thus hindering the eel's escape. By combining the conical tubes on the conical openings with those on the conical mesh, a "dual-entry structure" is formed, further confusing the eels, reducing their alertness, significantly decreasing eel escapes, and increasing the catch per capture.

[0018] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0019] Reference Figure 1-4This utility model discloses a trapping device for rice paddy eel farming, comprising: a trapping cage 1. Considering the complex habitat of eels and the low trapping efficiency caused by the single entrance of traditional trapping devices, the trapping cage 1 is provided with multiple conical cage openings 2 on its side surface. A conical mesh tube 7 is fixedly connected to the inner surface of the trapping cage 1. The multiple conical cage openings mimic the natural cave environment of eels, distracting them and increasing the probability of entry. Together with the conical flexible tube 6, a dual entrance structure is formed to improve the trapping efficiency. All the multiple conical cage openings 2 are connected to the conical mesh tube 7. Considering the problem that eels can easily escape from a single opening, the inner walls of the multiple conical cage openings 2 are connected to one side of the conical mesh tube 7 with conical flexible tubes 6. Due to their soft properties, the conical flexible tube 6 will collapse, so that the eels can only enter in one direction and cannot escape in the opposite direction, significantly reducing the escape rate.

[0020] In summary, the improvement of this embodiment lies in:

[0021] Based on the burrowing habits of eels, multiple small conical openings 2 are designed to mimic the "cave environment" where eels naturally inhabit, thus distracting them and increasing the probability of entry. The conical structure has a narrow entrance and a wide interior, making it easy for eels to enter but difficult for them to escape directly in the opposite direction. After the eel enters the opening, the conical flexible tube 6 collapses due to its soft nature, preventing the other end from forming a regular channel and thus preventing the eel from escaping in the opposite direction. The conical flexible tube 6 on the conical opening 2, together with the conical flexible tube 6 on the conical mesh tube 7, can form a "double entrance structure," further confusing the eels, reducing their alertness, significantly reducing eel escape, and increasing the catch per batch.

[0022] Based on the above, other structures also need to be disclosed in detail, such as:

[0023] Reference Figure 2 , Figure 3 To facilitate the placement and cleaning of bait, the trap 1 is equipped with multiple bait placement devices that can be detachably connected. The bait placement devices include: bait cage 9, insertion hole 8, and sealing plug 5. Insertion hole 8 is located on the trap 1. The bait cage 9 is threaded to the inner wall of the trap 1. The sealing plug 5 is threaded to the inlet of the bait cage 9. The bait cage 9 is connected to the trap 1. The sealing plug facilitates the placement of bait into the bait cage 9.

[0024] Reference Figure 1 , Figure 3 To facilitate the removal of the captured eels, the trap 1 is equipped with a trap door 3. A cover plate 4 is movably connected to the front surface of the trap door 3. Both the trap door 3 and the cover plate 4 are provided with screw holes 11. A fixing bolt 10 is threaded into the inner wall of the screw hole 11. After opening the cover plate 4, the eel can be removed directly by hand or with a soft tool, avoiding scratches from hard objects and reducing stress response.

[0025] Working principle: This rice paddy eel catching device is based on the eel's habit of burrowing and being highly alert, so as to achieve efficient catching. The main body of the device is the catching cage 1, and multiple small conical cage openings 2 are set on its side surface. These cage openings imitate the burrow environment where the eel naturally lives, distract its attention and increase the probability of entering.

[0026] Each conical cage opening 2 is connected to the internal conical mesh tube 7 and extends into a conical flexible tube 6, forming a "double entrance structure"—the eel can easily squeeze in through the narrow conical entrance, but due to the soft nature of the conical flexible tube 6, the internal channel will naturally collapse after entering, making it impossible to form a regular escape path. Furthermore, the double structure of the conical mesh tube 7 and the conical flexible tube 6 further confuses the eel, significantly reducing its alertness and the possibility of escape.

[0027] In terms of baiting, a detachable bait cage 9 is installed inside the trap 1. It is fixed to the inner wall of the cage through the insertion hole 8. The threaded sealing plug 5 can prevent the bait odor from dissipating too early and facilitate the replenishment of bait to ensure a continuous feeding effect.

[0028] During capture operations, the movable cover 4 of the cage door 3 is opened, and double locking is achieved through the screw hole 11 and the fixing bolt 10, which ensures the stability of the cage door and facilitates quick opening.

[0029] When removing the eels, they can be taken out directly by hand or with a soft tool through the cage door, avoiding scratches from hard objects and reducing stress on the eels. Through the synergistic effect of the biomimetic entrance design, one-way escape prevention structure and convenient operating system, the device achieves a comprehensive performance improvement of high trapping efficiency, low escape rate and user-friendly operation.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
