The base also has a through groove communicating with the receiving hole. One end of the screw is fixed to the limiting rod, and the end of the screw away from the limiting rod extends through the through groove to the outside of the receiving hole. The nut is threadedly connected to the screw.

[0009] Furthermore, there are multiple and the same number of both the limiting component and the vibration spring, with each vibration spring corresponding to one limiting component.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] In the specific embodiments provided in this disclosure, an earthworm screening device is provided, with reference to... Figures 1 to 7 As shown, the earthworm screening device includes a base 1, a box 2, and a drive mechanism 3. The base 1 and the box 2 are connected by a vibration spring 4. The box 2 has a storage cavity, which includes an installation part 201 and a screening part 202. The screening part 202 is arranged around the outside of the installation part 201 and has a sieve hole 2021. The installation part 201 has a mounting position for mounting the drive mechanism 3, and the drive mechanism 3 is used to drive the box 2 to vibrate.

[0034] Through the above technical solution, the base 1 and the housing 2 are connected by the vibration spring 4, enabling the drive mechanism 3 to more effectively drive the housing 2 to generate large-amplitude vibrations, thereby significantly improving screening efficiency. Compared with large-scale equipment in the prior art, this earthworm screening device adopts a compact structural design, which optimizes the vibration amplitude and screening effect, making it suitable for small-scale applications.

[0035] Specifically, the housing 2 has a storage cavity, which is divided into an installation section 201 and a screening section 202. The screening section 202 is arranged around the installation section 201 and has sieve holes 2021, which effectively separates earthworms from impurities such as soil and organic residues, ensuring the efficiency and accuracy of screening. At the same time, the installation section 201 has a mounting position for firmly fixing the drive mechanism 3, thereby ensuring the stable operation of the vibration source and preventing the vibration source from directly acting on the screening area. This not only avoids the violent impact of vibration on earthworms and reduces the risk of earthworm damage, but also facilitates the disassembly and maintenance of the equipment.

[0036] For example, the vibration spring 4 makes the vibration between the vibration source and the screening section 202 more uniform, greatly improving the screening effect and providing better shock absorption and buffering, preventing equipment damage or damage to individual earthworms due to excessive vibration. Overall, this earthworm screening device has a compact structure, is easy to maintain, and is suitable for home breeding, small farms, and scientific research experiments.

[0037] In some implementations, reference Figure 2 and Figure 4As shown, a limiting component 5 is installed on the base 1. The limiting component 5 includes a limiting rod 501, a lifting spring 502, a screw 503, and a nut 504. The base 1 has a receiving hole 101 for receiving the limiting rod 501. One end of the lifting spring 502 abuts against the bottom surface of the receiving hole 101, and the other end abuts against the limiting rod 501. The lifting spring 502 allows the end of the limiting rod 501 facing away from the lifting spring 502 to extend outside the base 1 through the opening of the receiving hole 101. The portion of the limiting rod 501 extending out of the receiving hole 101 is located inside the vibration spring 4. The base 1 also has a through groove 102 communicating with the receiving hole 101. One end of the screw 503 is fixed to the limiting rod 501, and the screw 503 faces away from the limiting rod. One end of 501 extends through the through groove 102 to the outside of the receiving hole 101. Nut 504 is threadedly connected to screw 503. Personnel can adjust the length of the portion of the limiting rod 501 extending out of the receiving hole 101 by holding the portion of screw 503 extending out of the receiving hole 101. After adjusting to a suitable length, the position of screw 503 and limiting rod 501 is locked and fixed by nut 504. That is, by adjusting the extension length of limiting rod 501, the swaying amplitude of vibration spring 4 can be limited. The longer the length of limiting rod 501 extending out of the receiving hole 101, the smaller the vibration amplitude of box 2 during screening. Conversely, the shorter the length of limiting rod 501 extending out of the receiving hole 101, the greater the vibration amplitude of box 2 during screening.

[0038] For example, the coordinated operation of the top limit rod 501, the lifting spring 502, the screw 503 and the nut 504 enables dynamic control of the vibration amplitude, allowing operators to flexibly set the vibration stroke according to different screening requirements, effectively adapting to changes in different earthworm species, screening material states or usage environments.

[0039] In some implementations, reference Figure 1 , Figure 2 and Figure 4 As shown, there are multiple and the same number of limiting components 5 and vibration springs 4, and each vibration spring 4 is matched with one limiting component 5. That is, each vibration spring 4 has a limiting rod 501 on its inner side, so that the vibration amplitude of each vibration spring 4 can be dynamically controlled.

[0040] For example, since each limiting component 5 can be adjusted independently, personnel can set different amplitude limits for different working conditions to achieve directional and controllable vibration. For instance, when the material being screened is uneven or the load on the box 2 is asymmetrical, the center of gravity can be dynamically balanced by finely adjusting the length of each limiting rod 501, thereby further optimizing the screening effect.

[0041] In some implementations, reference Figure 2As shown, the screening unit 202 includes a base plate 2022 and side panels 2023 fixed to the base plate 2022. Both the base plate 2022 and the side panels 2023 are provided with screen holes 2021. Multiple side panels 2023 are arranged around the base plate 2022. During earthworm screening, impurities such as soil and organic residue can not only be separated downwards through the screen holes 2021 of the base plate 2022, but also achieve lateral separation through the screen holes 2021 of the side panels 2023 when subjected to lateral vibration. This effectively expands the screening area and screening path, improving overall separation efficiency. Simultaneously, the surrounding arrangement of the side panels 2023 prevents earthworms from escaping during screening, reducing losses during the screening process.

[0042] In some implementations, reference Figure 2 As shown, the mounting part 201 includes a mounting plate 2011 and a baffle 2012. The mounting plate 2011 is fixedly connected to the base plate 2022, and the baffle 2012 is fixedly connected between the mounting plate 2011 and the base plate 2022. Multiple baffles 2012 are arranged around the mounting plate 2011 to enclose and form the mounting part 201. Simultaneously, a partition plate 6 is provided inside the mounting part 201 to divide it into a first mounting cavity and a second mounting cavity. The bottom surfaces of both the first and second mounting cavities are... The enclosure is equipped with mounting positions. For example, drive mechanisms 3 can be installed in both the first and second mounting cavities, enabling the housing 2 to perform more powerful screening vibrations. Specifically, by installing drive mechanisms 3 in the first and second mounting cavities respectively, the distribution and vibration uniformity of the drive mechanisms 3 are effectively improved, ensuring a more uniform and stable vibration amplitude during the screening process. The partition plate 6 not only optimizes the utilization of internal structural space but also avoids interference between drive mechanisms 3, improving operational reliability and stability. During the screening process, the drive mechanisms 3 in the first and second mounting cavities work together to provide strong vibration force, significantly enhancing the screening capacity of the housing 2 and making material separation more efficient.

[0043] In some implementations, reference Figure 2 , Figure 3 and Figure 7 As shown, the drive mechanism 3 includes a pneumatic vibrator 301, a cover plate 302, and a fixing plate 303. The cover plate 302 is fixedly connected to the fixing plate 303, and a first handle 3021 is provided at the end of the cover plate 302 facing away from the fixing plate 303. The first handle 3021 facilitates manual handling or disassembly of the drive assembly, improving the ease of operation and safety. The end face of the fixing plate 303 facing away from the cover plate 302 is provided with a first stud 7 for installing the pneumatic vibrator 301, which is used to fix the pneumatic vibrator 301 by means of threaded connection, ensuring that the vibrator can still work stably under high-frequency vibration.

[0044] Furthermore, along the axial direction of the first stud 7, the cross-sectional area of ​​the cover plate 302 is greater than that of the fixed plate 303. That is, the cross-sectional area of ​​the cover plate 302 is greater than that of the fixed plate 303, which is beneficial to enhance the support effect of the cover plate 302 on the drive component. At the same time, it forms a stress buffer structure with a larger top and a smaller bottom in terms of structural mechanics, which optimizes the stress distribution. Specifically, the cover plate 302 is provided with a through hole, and the mounting position has a second stud 2013 and a guide port 2014. When the drive mechanism 3 is set in the mounting position, the pneumatic vibrator 301 extends to the bottom of the housing 2 through the guide port 2014 and the second stud 2013 passes through the through hole. At this time, the cover plate 302 covers the top of the guide port 2014.

[0045] For example, the pneumatic vibrator 301 extends to the bottom of the housing 2 via the guide port 2014 to facilitate personnel connecting the air hose.

[0046] In some implementations, reference Figure 6 As shown, it also includes a cover 8, which has an embedding groove 801. When the cover 8 covers the mounting part 201, part of the baffle 2012 is embedded in the embedding groove 801. That is, by providing a cover 8 with an embedding groove 801, it can effectively prevent external debris, dust, moisture and other substances from entering the mounting part 201, and play a good sealing and protection role. At the same time, the baffle 2012 embedded in the embedding groove 801 forms a positioning and limiting structure, which facilitates quick alignment during installation and disassembly, and improves assembly efficiency and maintenance convenience.

[0047] For example, in order to improve the connection stability between the cover 8 and the baffle 2012, ear plates can be provided on both the cover 8 and the baffle 2012. That is, when the cover 8 covers the mounting part 201, the two ear plates overlap, and then the cover 8 and the baffle 2012 are fixedly connected by bolts through the ear plates.

[0048] In some implementations, reference Figure 6 As shown, the upper surface of the cover 8 is also provided with a guide 802. The end of the guide 802 away from the cover 8 is provided with a second handle 803. The second handle 803 is provided to facilitate personnel to move and transfer the cover 8 and the guide 802. The guide 802 has a guide slope 8021. The guide 802 is constructed in the shape of a frustum. The guide slope 8021 of the guide 802 can guide the breeding medium (soil, organic residue and other impurities) mixed with earthworms, so that it can fall accurately into the screening section 202 for screening.

[0049] Specifically, the guide slope 8021 can effectively guide the irregularly falling aquaculture medium, prevent it from deviating from the landing point or splashing, avoid material scattering causing waste or pollution, and ensure that the aquaculture medium falls into the screening section 202 in a concentrated manner.

[0050] In some implementations, reference Figure 1 As shown, multiple support legs 9 are fixedly connected to the lower surface of the base 1, and each support leg 9 has a rubber pad 901 at its bottom. The rubber pad 901 has excellent elasticity and shock absorption performance, which can effectively absorb and attenuate high-frequency vibrations during the screening process, reduce the impact of vibration on the ground, reduce noise transmission and environmental interference, and improve the overall operational stability of the device.
