Description

Technical Field

[0001] This utility model belongs to the field of agricultural engineering technology, specifically, it relates to an earthworm escape prevention device for multi-scenario applications. Background Technology

[0002] Currently, earthworm culture containers or potted containers are generally used in the breeding and scientific research of earthworms. However, due to the strong mobility of earthworms, they often escape by crawling out along the inner wall of the culture container during the breeding process, which has an adverse effect on breeding management and data analysis in scientific research.

[0003] Current methods for preventing earthworms from escaping have significant drawbacks: sealing with tape results in poor air permeability and is unsuitable for planting systems; Velcro is ineffective at preventing escape and is easily damaged; nylon mesh is unsuitable for crop planting and outdoor environments; and top baffles cannot effectively prevent highly mobile earthworms from escaping.

[0004] In view of this, this utility model is proposed. Utility Model Content

[0005] To address the issues of preventing earthworm escape, the use of adhesive seals leads to poor air permeability and is unsuitable for planting systems; Velcro offers poor escape prevention and is easily damaged; nylon mesh is unsuitable for crop cultivation and outdoor environments; and top baffles are ineffective in preventing the escape of highly mobile earthworms. The basic concept of this utility model is as follows:

[0006] An earthworm escape prevention device for multiple application scenarios includes a box body. The bottom of the box body is provided with supporting feet and the side is provided with a handle. Removable inner curved pipes are installed at the four corners of the inner wall of the top of the box body, and removable outer curved pipes are installed at the four corners of the outer wall of the top of the box body. Removable middle curved pipes are installed in the middle part of the sides of the inner and outer walls of the top of the box body. The inner curved pipes, outer curved pipes and middle curved pipes are all 180° arc-shaped curved pipes.

[0007] In a preferred embodiment of this utility model, the inner and outer walls of the top of the box are provided with downwardly inclined slots, and the inner bend, outer bend and middle bend are provided with locking blocks that are adapted to the slots.

[0008] In a preferred embodiment of this utility model, the inclination angle of the card slot is 15°, a rubber pad is provided inside the card slot, and the contact part between the rubber pad and the card block is provided with anti-slip teeth.

[0009] In a preferred embodiment of this utility model, the corner curvature of the inner and outer bends matches the right-angle edge of the box. The box is provided with different sizes, and the single-segment length of the middle bend is a standard size. The middle bend is spliced ​​end to end and installed on the side of the inner and outer walls of the top of the box. Different numbers of middle bends are used to adapt to boxes with different side lengths. The increased side length of the box is an integer multiple of the single-segment length of the middle bend.

[0010] In a preferred embodiment of this utility model, the bottom of the box is provided with a drain hole, and a filter screen is installed in the drain hole.

[0011] In a preferred embodiment of this utility model, the arc diameters of the inner bend, outer bend, and middle bend are provided in various sizes, and the materials of the inner bend, outer bend, and middle bend are PVC or acrylic.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This invention can be used not only for cultivating organisms, but also for holding earthworm bait for fishing. Installing curved pipes in farmland and forests can control earthworm migration over a large area. It adopts segmented modular curved pipes and uses curved surface mechanics to prevent escape. It can be quickly connected by inclined slots and blocks. The middle curved pipes can be flexibly added or removed to adapt to different box side lengths.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0022] Example 1:

[0023] like Figures 1 to 4 As shown, an earthworm escape prevention device for multiple application scenarios includes a box 1. The bottom of the box 1 is provided with support feet 10 and the side is provided with handles 11. Removable inner bends 4 are installed at the four corners of the inner wall of the top of the box 1, and removable outer bends 5 are installed at the four corners of the outer wall of the top of the box 1. Removable middle bends 6 are installed in the middle part of the sides of the inner and outer walls of the top of the box 1. The inner bends 4, outer bends 5 and middle bends 6 are all 90° arc bends. In this setup, the main body of the box 1 is used to contain earthworms and provide a cultivation environment. The support legs 10 lift the box 1 off the ground to prevent the bottom from getting damp or coming into contact with impurities, while also facilitating bottom ventilation or drainage. The handle 11 makes it easy to carry and move the device, improving operational convenience. The inner curved pipe 4 is installed at the corner of the inner wall of the box 1 to form a 90° arc barrier, using curved surface mechanics to reduce the surface area for earthworms to climb on, preventing them from escaping. The outer curved pipe 5 is installed at the corner of the outer wall of the box 1, similarly forming an outer arc barrier to prevent external earthworms or other animals from entering the box. The middle curved pipe 6 is installed in the middle of the side of the box 1, and by splicing and adapting to different side lengths, it ensures that each side forms a continuous escape-proof structure.

[0024] like Figures 1 to 4 As shown in the specific embodiment, both the inner and outer walls of the top of the housing 1 are provided with downwardly inclined slots 9, and the inner bend 4, outer bend 5, and middle bend 6 are provided with locking blocks 7 that are adapted to the slots 9. In this configuration, the slots 9 and the locking blocks 7 on the inner bend 4, outer bend 5, and middle bend 6 cooperate to achieve detachable locking. The gravitational force generated by the inclined angle enhances the connection stability, and the inner bend 4, outer bend 5, and middle bend 6 are fixed by pushing and locking. Disassembly is performed along the inclined direction, which is convenient and flexible.

[0025] like Figures 1 to 4 As shown, the slot 9 is further tilted at an angle of 15°, and a rubber pad 8 is provided inside the slot 9. The contact area between the rubber pad 8 and the locking block 7 is provided with anti-slip teeth. In this configuration, the slot 9 with a tilt angle of 15° optimizes the clamping mechanical structure, allowing the inner bend 4, outer bend 5, and middle bend 6 to generate a horizontal component force through their own weight, thereby strengthening the clamping effect and preventing slippage. The rubber pad 8 fills the gap between the slot 9 and the locking block 7, and the anti-slip teeth increase the friction, preventing the inner bend 4, outer bend 5, and middle bend 6 from sliding, while also buffering the impact of disassembly and assembly, and protecting the components.

[0026] like Figures 1 to 4 As shown, furthermore, the corner curvature of the inner bend 4 and the outer bend 5 matches the right-angle edge of the box 1. The box 1 is provided with different sizes, and the single-segment length of the middle bend 6 is a standard size. The middle bend 6 is spliced ​​end to end and installed on the inner and outer sides of the top of the box 1. Different numbers of middle bend 6 are used to adapt to box 1 with different side lengths. The increased side length of the box 1 is an integer multiple of the single-segment length of the middle bend 6. In this setting, the corner curvature matching of the inner bend 4 and the outer bend 5 ensures that the inner bend 4 and the outer bend 5 fit seamlessly with the right-angle edge of the box 1, forming a continuous and smooth curved surface, eliminating the point of force for earthworms to climb. The single-segment length of the middle bend 6 is standardized. By increasing or decreasing the number of splices, it adapts to box 1 of different sizes. The difference in side length of box 1 of different sizes is an integer multiple of the single-segment length of the middle bend 6, realizing modular and flexible expansion.

[0027] like Figures 1 to 4 As shown, the bottom of the box 1 is further provided with a drainage hole 2, and a filter screen 3 is installed in the drainage hole 2. In this configuration, the drainage hole 2 drains the water accumulated at the bottom of the box 1 to avoid the breeding environment being too wet and affecting the survival of earthworms. The filter screen 3 covers the drainage hole 2, allowing water to flow through but preventing earthworms from being lost with the water, thus taking into account both drainage and escape prevention functions.

[0028] like Figures 1 to 4 As shown, the inner bend 4, outer bend 5, and middle bend 6 have various arc diameters. The inner bend 4, outer bend 5, and middle bend 6 are made of PVC or acrylic. In this design, the PVC and acrylic bends have smooth surfaces, effectively reducing friction for earthworms climbing. The materials are lightweight and corrosion-resistant, suitable for use in various laboratory and outdoor settings. Furthermore, a slip-enhancing agent can be applied to further improve the escape-prevention effect.

[0029] Example 2:

[0030] The difference between this embodiment and the previous one is that the inner bend 4, outer bend 5, and middle bend 6 are connected to the cement wall by fasteners. In this setup, since earthworms can crawl on glass walls, and this device does not rely on the smoothness of the box 1 to prevent earthworms from escaping, the material of the box 1 can be very flexible. In the wild, it can even be a cement wall. Installing the bends in farmland and forests can control earthworm migration over a large area.

[0031] The implementation principle of a multi-scenario earthworm escape prevention device in this embodiment is as follows: The bottom of the box 1 is equipped with support feet 10 and drainage holes 2 with filters 3. A handle 11 is provided on the side. The inside of the box 1 is filled with soil or other substrate for cultivating earthworms, and crops can be planted as needed. The top inner wall and outer wall are respectively connected by slots 9 at a 15° angle with built-in anti-slip serrated rubber pads 8, allowing for the detachable connection of an inner curved pipe 4, an outer curved pipe 5, and a straight intermediate curved pipe 6 in a 90° arc shape. The corner curvatures of the inner curved pipe 4 and outer curved pipe 5 match the right-angle edges of the box 1. The intermediate curved pipe 6 has a standard length per segment. The number of segments can be increased or decreased by splicing the ends to accommodate boxes 1 with different side lengths. The difference in side length between different sizes of box 1 is an integer multiple of the length of a single segment of the intermediate curved pipe 6. The curved surface significantly reduces the earthworm's surface area for support, preventing it from escaping. The inner bend 4, outer bend 5, and middle bend 6 are adjusted according to the different body shapes of earthworms. For relatively large, deep-dwelling earthworms, a larger diameter is used, and vice versa. The PVC or acrylic bends have smooth surfaces and can be coated with a slip agent to enhance their effect. The inclined slot 9 and the locking block 7 work together to achieve a stable connection using the component of gravity and the anti-slip teeth of the rubber pad 8. Disassembly is performed along the inclined direction. Damaged sections can be replaced individually. When not in use, the device can be disassembled and stored. The support feet 10 and handles 11 facilitate the placement and transport of the device. This device can be used not only for cultivating organisms but also for holding earthworm bait for fishing. Installing the bends in farmland and forests can control earthworm migration over a large area.
