Description

Technical Field

[0001] This utility model relates to the technical field of soil treatment devices, and more specifically, to a soil turning and microplastic collection device. Background Technology

[0002] In recent years, the threat of microplastic pollution to soil ecosystems has become increasingly prominent. Due to their non-degradability and persistence, microplastics can accumulate in the soil environment over a long period of time, harming soil organisms such as earthworms, insects, and microorganisms, thereby affecting soil health and fertility. Moreover, microplastics can be absorbed through plant roots or penetrate into crop tissues through the epidermis and be transferred to humans along the food chain, leading to the potential accumulation of health risks (such as inflammatory responses and endocrine disorders). Therefore, it is necessary to collect microplastics in the soil to mitigate environmental pollution.

[0003] In related technologies, the soil is usually turned over manually, then poured into a sieve and shaken to sift out the microplastics mixed in the soil. This method of combining manual labor with sieves has the problems of high labor costs and low separation efficiency. Utility Model Content

[0004] The problem this invention addresses is how to improve the efficiency of screening and separating microplastics in soil.

[0005] To address the aforementioned problems, this utility model provides a soil turning and microplastic collection device.

[0006] In a first aspect, this utility model provides a soil turning and microplastic collection device, including a mobile tool and a main structure. The main structure includes a support, a driving mechanism, a rotating shaft assembly, a soil turning assembly, a screen structure, and a storage structure. The support is mounted on the mobile tool. The rotating shaft assembly passes through the support, and the soil turning assembly is connected to the rotating shaft assembly. The driving mechanism is driven to the end of the rotating shaft assembly to drive the rotating shaft assembly to rotate the soil turning assembly, thereby turning the soil. The screen structure is movably mounted on the support and is positioned opposite and spaced apart from the soil turning assembly. The soil turning assembly is used to turn the soil onto the surface of the screen structure. The storage structure is connected to the end of the screen structure away from the soil turning assembly and is used to collect the microplastics left after being screened by the screen structure.

[0007] Optionally, the rotating shaft assembly includes a drive rod and a rotating shaft, with the end of the drive rod connected to the drive mechanism;

[0008] The rotating shaft is embedded in the driving rod and is used to rotate relative to the driving rod; the driving rod is provided with a plurality of clearance notches at intervals along its own axial direction, and the soil turning assembly includes a plurality of soil turning parts, each of which passes through the corresponding clearance notch and is connected to the rotating shaft.

[0009] Optionally, the soil-turning part includes a connecting plate and a soil-turning shovel, one end of the connecting plate is connected to the rotating shaft, and the other end of the connecting plate away from the rotating shaft is connected to the soil-turning shovel.

[0010] Optionally, the soil-turning shovel is provided with a through-hole structure.

[0011] Optionally, the rotating shaft assembly further includes buffer springs, with buffer springs respectively installed between the opposite side walls of the connecting plate and the inner wall of the clearance notch.

[0012] Optionally, the support includes a support plate, a support frame, and a fixed seat. The rotating shaft assembly passes through the support frame, the support frame is connected to the moving tool, the support plate is connected to the end of the support frame away from the moving tool, the two support plates are arranged opposite to each other and spaced apart, the inner walls of the support plates are respectively fixedly connected to the corresponding fixed seats, the screen structure is arranged between the two support plates, and the ends of the screen structure are respectively movably connected to the corresponding fixed seats.

[0013] Optionally, the screen structure includes a screen body, a return spring, and a connecting block. The return spring is connected between the fixed base and the connecting block, and the ends of the screen body are respectively fixedly connected to the corresponding connecting blocks. The screen body has multiple mesh holes.

[0014] Optionally, the fixed base includes a first slider, a second slider, and a first plate and a second plate fixed at an angle to the support plate. The first slider is slidably connected to the first plate, and the second slider is slidably connected to the second plate. The return spring is installed on the first slider and the second slider respectively, and the end of the return spring away from the fixed base is fixedly connected to the connecting block.

[0015] Optionally, the second plate is located on the side of the connecting block of the screen structure away from the soil turning assembly.

[0016] Optionally, the soil turning and microplastic collection device further includes a striking component, which includes a linkage block and a striking rod. The linkage block is connected to the end of the rotating shaft assembly away from the driving device.

[0017] The beneficial effects of this utility model's soil turning and microplastic collection device are:

[0018] The soil turning and microplastic collection device mainly consists of a main structure and a mobile tool. The support frame of the main structure can be fixedly installed on the side or tail end of the mobile tool.

[0019] Microplastics can be collected in the following way: During the movement of the main structure on the soil by a mobile tool, a rotating shaft assembly is driven to rotate, causing the soil-turning assembly to rotate in a circular motion. This rotation turns the soil over and onto a screen structure, where soil particles fall through the mesh. Microplastics in the soil on the screen structure roll down into a collection structure under gravity. Compared to related technologies that rely on manual soil turning and sieving, which suffer from low separation efficiency, this invention uses a mobile tool in conjunction with the soil-turning assembly, screen structure, and collection structure to automatically turn and flip the soil onto the screen structure for sieving. The collection structure then collects the microplastics left after sieving, effectively reducing labor costs and improving the separation efficiency of microplastics from the soil.

[0032] To address the problems existing in the aforementioned related technologies, this embodiment provides a soil turning and microplastic collection device.

[0033] like Figure 1 As shown in the figure, this utility model provides a soil turning and microplastic collection device, including a mobile tool and a main structure. The main structure includes a support 1, a driving component 2, a rotating shaft assembly 3, a soil turning assembly 4, a screen structure 5, and a storage structure 6. The support 1 is mounted on the mobile tool. The rotating shaft assembly 3 passes through the support 1, and the soil turning assembly 4 is connected to the rotating shaft assembly 3. The driving component 2 is driven to the end of the rotating shaft assembly 3 to drive the rotating shaft assembly 3 to rotate the soil turning assembly 4, thereby turning the soil. The screen structure 5 is movably mounted on the support 1 and is positioned opposite and spaced apart from the soil turning assembly 4. The soil turning assembly 4 is used to turn the soil onto the surface of the screen structure 5. The storage structure 6 is connected to the end of the screen structure 5 away from the soil turning assembly 4 and is used to collect the microplastics left after being screened by the screen structure 5.

[0034] Specifically, mobile tools are agricultural mobile machinery that can move on the soil, such as loaders, electric vehicles, agricultural robots, and handcarts.

[0035] The mobile tool may include a tool body and a mounting bracket 8. The mounting bracket 8 may be located on the left or right side of the tool body, or at the rear end of the tool body. The support 1 of the main structure may be fixed to the mounting bracket 8 by bolts and fasteners. The connection method between the mounting bracket 8 and the tool body may refer to the connection method between the tow body (e.g., rotary tiller, plow, weeding implement) and the main body of the tiller, or may use existing linkage components and bolt fasteners for connection. No specific limitation is made here.

[0036] The rotating shaft assembly 3 can be inserted into the bracket 1, so that the rotating shaft assembly 3 can rotate relative to the bracket 1; the driving device 2 is used to drive the rotating shaft assembly 3 and drive the soil turning assembly 4 to rotate, and the soil turning assembly 4 is used to turn the soil during the rotation.

[0037] The screen structure 5 is movably mounted on the support 1, meaning that the screen structure 5 can move relative to the support 1 (e.g., shake). The screen structure 5 can be located on the side of the soil turning component 4 away from the moving tool. The screen structure 5 is inclined relative to the horizontal plane, so that the microplastics left after the screen structure 5 screens the soil roll into the collection structure 6, thereby reducing the microplastic content in the soil and improving the soil environment.

[0038] Storage structure 6 can adopt structures such as collection boxes and collection bags.

[0039] In this embodiment, the soil turning and microplastic collection device mainly includes a main structure and a mobile tool. The support 1 of the main structure can be fixedly installed on the side or tail end of the mobile tool.

[0040] Microplastics can be collected in the following way: During the movement of the main structure on the soil by a mobile tool, the drive component 2 drives the rotating shaft assembly 3 to rotate, causing the soil-turning assembly 4 to rotate in a circular motion. The rotation of the soil-turning assembly 4 turns and flips the soil onto the screen structure 5. At this time, the soil on the screen structure 5 can be sieved through the mesh of the screen structure 5 and fall off. Microplastics in the soil on the screen structure 5 can roll down along the screen structure 5 under gravity into the collection structure 6. This method is superior to the manual soil turning used in related technologies. Regarding the issue of low separation efficiency of microplastics from soil when sieving them using a screen, this invention addresses this problem by having a moving tool work in conjunction with the soil-turning component 4, the screen structure 5, and the storage structure 6 in the main structure. This allows the soil to be automatically turned over and flipped onto the screen structure 5 for sieving. The storage structure 6 then collects the microplastics left after sieving by the screen structure 5. This not only effectively reduces labor costs but also significantly improves the separation efficiency of microplastics from soil, reducing the content of microplastics in the soil and thus effectively improving the soil environment.

[0041] Optionally, combined Figure 2 and Figure 3 As shown, the rotating shaft assembly 3 includes a drive rod 31 and a rotating shaft 32, and the end of the drive rod 31 is connected to the drive device 2;

[0042] The rotating shaft 32 is embedded in the driving rod 31 and is used to rotate relative to the driving rod 31; the driving rod 31 is provided with a plurality of clearance notches 311 at intervals along its own axial direction; the soil turning assembly 4 includes a plurality of soil turning parts 41, each of the soil turning parts 41 passing through the corresponding clearance notch 311 and being connected to the rotating shaft 32.

[0043] Specifically, the driving device 2 can be a rotary motor, a rotary hydraulic cylinder, a rotary pneumatic cylinder, or the like.

[0044] The output shaft of the drive device 2 can be fixedly connected to the drive rod 31 via a coupling.

[0045] The drive rod 31 can be a hollow rod structure, allowing the rotating shaft 32 to pass through it and rotate relative to it. Both the drive rod 31 and the rotating shaft 32 can be made of a single rod to ensure the mechanical strength of the shaft assembly.

[0046] The number of clearance notches 311 on the drive rod 31 can be greater than or equal to the number of soil turning parts 41. Each part of the soil turning part 41 passes through the clearance notch 311 and connects to the drive rod 31 to achieve the connection between the soil turning part 41 and the rotating shaft 32 of the rotating shaft assembly 3.

[0047] The arrangement direction of the multiple soil turning parts 41 is parallel to the extension direction of the rotating shaft assembly 3 to ensure that the multiple soil turning parts 41 can turn the soil synchronously.

[0048] In this optional embodiment, since the drive unit 2 is fixedly connected to the end of the drive rod 31, and a portion of each soil turning part 41 passes through the clearance notch 311 of the drive rod 31 and is connected to the rotating shaft 32, the drive unit 2 can drive the multiple soil turning parts 41 and the rotating shaft 32 to rotate through the drive rod 31 to perform soil turning action; since the multiple soil turning parts 41 can be spaced apart along the axial direction of the rotating shaft assembly 3, it can be ensured that the multiple soil turning parts 41 can turn the soil synchronously, thereby reducing the soil turning resistance by increasing the soil turning area through the spaced multiple soil turning parts 41. Since each turning part 41 is inserted into the corresponding clearance notch 311 and connected to the rotating shaft 32 inside the drive rod 31, the drive rod 31 drives the turning part 41 and the rotating shaft 32 to rotate through the edge of the clearance notch 311 during rotation. In other words, the drive rod 31 does not always rotate synchronously with the turning part 41 and the rotating shaft 32, thereby ensuring that the turning part 41 of the turning assembly 4 has a certain centrifugal force, which can better turn the soil onto the screen structure 5 through the turning part 41, thereby improving the turning effect of turning the soil onto the screen structure 5.

[0049] Optionally, combined Figure 3 As shown, the soil turning section 41 can adopt the following structure: the soil turning section 41 includes a connecting plate 411 and a soil turning shovel 412. One end of the connecting plate 411 is connected to the rotating shaft 32, and the end of the connecting plate 411 away from the rotating shaft 32 is connected to the soil turning shovel 412.

[0050] Specifically, one end of the connecting plate 411 is inserted into the clearance notch 311 of the drive rod 31 and can be fixedly connected to the rotating shaft 32 by welding, and the end of the connecting plate 411 away from the rotating shaft 32 can be fixedly connected to the soil turning shovel 412.

[0051] The soil turning shovel 412 can be a straight plate structure or an L-shaped shovel structure.

[0052] The soil turning shovel 412 is fixedly connected to the connecting plate 411 at an angle, for example, the angle between the two can be a right angle or an obtuse angle.

[0053] In this optional embodiment, the driving device 2 can drive the driving rod 31 to rotate. During the rotation of the driving rod 31, the edge of the clearance notch 311 of the driving rod 31 drives the soil turning part 41 and the rotating shaft 32 to rotate, so as to use the circumferential motion of the soil turning part 41 to perform soil shoveling action. For example, when the soil turning part 41 rotates, the edge of the clearance notch 311 of the driving rod 31 transmits the rotational force to the rotating shaft 32 and the soil turning shovel 412 through the connecting plate 411, thereby realizing the rotation action of each soil turning shovel 412.

[0054] Optionally, combined Figure 3 As shown, the soil turning shovel 412 is provided with a through hole structure 4121.

[0055] Specifically, at least one through hole structure 4121 can be made on each soil turning shovel 412.

[0056] In this optional embodiment, by opening a through hole structure 4121 on the soil turning shovel 412, not only can the weight of the soil turning shovel 412 be reduced, and the load on the driving component 2 be reduced accordingly, but the soil turning resistance during the soil turning action can also be reduced through the through hole structure 4121, reducing the possibility of overload damage to the driving component 2.

[0057] Optionally, combined Figure 3 As shown, the rotating shaft assembly 3 also includes a buffer spring 33, and buffer springs 33 are respectively installed between the opposite side walls of the connecting plate 411 and the inner wall of the clearance notch 311.

[0058] Specifically, the buffer spring 33 can be a compression spring, and at least one buffer spring 33 can be fixedly installed between each larger surface of the connecting plate 411 and the inner wall of the clearance notch 311. The larger surface of the connecting plate 411 refers to the side with the largest surface area among the multiple surfaces of the connecting plate 411.

[0059] In this optional embodiment, since a buffer spring 33 is provided between the inner wall of the clearance notch 311 of the connecting plate 411 and the drive rod 31, the soft support of the buffer spring 33 between the inner wall of the clearance notch 311 of the connecting plate 411 and the drive rod 31 makes the soil turning process smoother. The soil is thrown onto the screen structure 5 under the action of centrifugal force, which further improves the processing efficiency of separating microplastics from the soil.

[0060] Optionally, combined Figure 4As shown, the bracket 1 includes a support plate 11, a support frame 12, and a fixed seat 13. The rotating shaft assembly 3 passes through the support frame 12. The support frame 12 is connected to the moving tool. The support plate 11 is connected to the end of the support frame 12 away from the moving tool. The two support plates 11 are arranged opposite to each other and spaced apart. The inner walls of the support plates 11 are respectively fixedly connected to the corresponding fixed seats 13. The screen structure 5 is arranged between the two support plates 11, and the ends of the screen structure 5 are respectively movably connected to the corresponding fixed seats 13.

[0061] Specifically, the support frame 12 can adopt an inverted U-shaped frame structure. Pin holes are respectively opened on the two opposite side walls of the support frame 12. One end of the drive rod 31 can pass through one pin hole of the support frame 12 and be fixedly connected to the drive component 2. The end of the drive rod 31 or the rotating shaft 32 away from the drive component 2 passes through the other pin hole of the support frame 12. A bearing can be added between the rotating shaft assembly 3 and the pin hole of the support frame 12 to improve the rotational smoothness of the rotating shaft assembly 3 relative to the support frame 12.

[0062] The bracket 1 may include a support frame 12 and two support plates 11, wherein the support frame 12 and the support plates 11 are movable along... Figure 4 The support plates 11 are arranged along the Y-axis in the coordinate system, and the front end of the support plate 11 can be directly and fixedly connected to the rear end of the support frame 12, or fixedly connected by other components such as connecting rods. The spacing direction of the two support plates 11 can be the same as... Figure 4 In the coordinate system, the X-axis is arranged at intervals, and the two support plates 11 are fixedly connected to the fixed seat 13 by bolt fasteners, welding or other methods on the opposite side walls.

[0063] In this optional embodiment, since the support plate 11 is fixedly connected to the end of the support frame 12 away from the moving tool, and the soil turning component 4 is mounted on the support frame 12 through the rotating shaft component 3, and the screen structure 5 is movably mounted on the fixed seat 13, the soil turning component 4 and the screen structure 5 are spaced apart along the front and rear direction of the support 1, so that the soil turning action performed by the soil turning component 4 during the circumferential motion will not collide with the screen structure 5.

[0064] Optionally, combined Figure 5 As shown, the screen structure 5 includes a screen body 51, a return spring 52, and a connecting block 53. The return spring 52 is connected between the fixed base 13 and the connecting block 53. The ends of the screen body 51 are respectively fixedly connected to the corresponding connecting blocks 53. The screen body 51 is provided with a plurality of mesh holes.

[0065] Specifically, a return spring 52 can be provided between the fixed base 13 and the connecting block 53, and the two ends of the return spring 52 are fixedly connected to the fixed base 13 and the connecting block 53 respectively.

[0066] The return spring 52 can be a compression spring.

[0067] Because the soil is uneven, the screen body 51 can shake a certain amount during the slow movement of the moving tool, so that the soil falling on the screen body 51 can be screened.

[0068] The ends of the screen body 51 are fixedly connected to the corresponding connecting blocks 53 by means of bolts, fasteners, welding, etc.

[0069] The screen body 51 has multiple mesh holes arranged in an array. The diameter of the mesh holes can be smaller than the diameter of the microplastics and larger than the diameter of the soil particles. Therefore, the screen body 51 is mainly used to screen microplastics in the soil that are larger than the diameter of the soil particles.

[0070] The screen body 51 is inclined relative to the horizontal plane, meaning that the height of the front end of the screen body 51 (e.g., the end facing the soil turning component 4) is higher than the height of the rear end of the screen body 51 (e.g., the end away from the soil turning component 4).

[0071] In this optional embodiment, since the ends of the screen body 51 are respectively fixedly connected to the corresponding connecting blocks 53, and the connecting blocks 53 are connected to the fixed seat 13 of the support 1 through the return spring 52, in other words, the screen body 51 and the support 1 are connected through the return spring 52, so that the screen body 51 can move back and forth under the action of the return spring 52, thereby screening the soil that the soil turning component 4 flips and throws onto the screen body 51, so that the soil in the soil can be screened and fall through the mesh of the screen structure 5, and the microplastic particles in the soil can roll down along the screen structure 5 into the storage structure 6 under the action of gravity.

[0072] Optionally, combined Figure 5 and Figure 6 As shown, the fixed base 13 includes a first slider 131, a second slider 132, and a first plate 133 and a second plate 134 fixed at an angle to the support plate 11. The first slider 131 is slidably connected to the first plate 133, and the second slider 132 is slidably connected to the second plate 134. The return spring 52 is respectively installed on the first slider 131 and the second slider 132. The end of the return spring 52 away from the fixed base 13 is fixedly connected to the connecting block 53.

[0073] Specifically, the first plate 133 and the second plate 134 are fixedly connected at an included angle, and the first plate 133 and the second plate 134 are respectively fixedly connected to the side wall of the support plate 11; the first slider 131 and the second slider 132 are respectively slidably installed on the first plate 133 and the second plate 134.

[0074] The first slider 131 and the second slider 132 can be slidably connected to the first plate 133 and the second plate 134 respectively in the following ways: for example, the first plate 133 and the second plate 134 have a first through hole and a second through hole respectively. The first slider 131 can be inserted through the first through hole by a bolt fastener or a pin structure to achieve a slidable connection between the first slider 131 and the first plate 133. The second slider 132 can be inserted through the second through hole by a bolt fastener or a pin structure to achieve a slidable connection between the second slider 132 and the second plate 134.

[0075] One return spring 52 has its two ends fixedly connected to the bottom wall of the connecting block 53 and the top wall of the first slider 131 by means of hooking, bonding, or other methods. The other return spring 52 has its two ends fixedly connected to the rear end of the connecting block 53 and the second slider 132 by means of hooking, bonding, or other methods. The connecting block 53 is along... Figure 6 In the coordinate system, the sidewall opposite to the Z-axis is the bottom wall of connecting block 53, and connecting block 53 along... Figure 6 The sidewall opposite the Y-axis in the coordinate system is the rear end of the connecting block 53.

[0076] In this optional embodiment, one end of the reset spring 52 is fixedly connected to the connecting block 53, and the other end of the reset spring 52 can be slidably connected to the first plate 133 (or the second plate 134) through the first slider 131 (or the second slider 132). Thus, by increasing the movement and swing amplitude of the reset spring 52, the shaking amplitude of the screen body 51 can be effectively increased, thereby improving the sieving effect on the soil.

[0077] Optionally, the second plate 134 is located on the side of the connecting block 53 of the screen structure 5 away from the soil turning component 4.

[0078] In this optional embodiment, the second plate 134 of the fixing seat 13 is located at the rear end of the connecting block 53, so that the second plate 134 of the fixing seat 13 can limit the connecting block 53 and the screen body 51 at the corresponding position to prevent the screen body 51 from detaching from the fixing seat 13 and thus extend its service life.

[0079] Optionally, in addition to using the shaking generated by the movement of the aforementioned moving tool on uneven soil, the soil on the screen structure 5 can also be screened by using a striking component to strike the soil on the screen structure 5. For example, combined with... Figure 2 and Figure 4As shown, the soil turning and microplastic collection device also includes a striking component 7, which further includes a linkage block 71 and a striking rod 72. The linkage block 71 is connected to the end of the rotating shaft assembly 3 away from the driving component 2. One end of the striking rod 72 is connected to the linkage block 71, and the other end of the striking rod 72 is used to strike the screen structure 5 during the rotation of the rotating shaft assembly 3.

[0080] Specifically, the linkage block 71 can be fixedly connected to the end of the rotating shaft assembly 3 away from the driving component 2 by means of a sleeve connection, wherein the linkage block 71 can be sleeved on the end of the rotating shaft 32 (see Figure 2 As shown, the linkage block 71 can also be sleeved on the end of the drive rod 31. A locking pin can be used to pass through the linkage block 71 and be inserted into the end of the rotating shaft assembly 3 away from the drive component 2 to improve the connection stability between the linkage block 71 and the rotating shaft assembly 3.

[0081] One end of the striking rod 72 can be fixedly connected to the linkage block 71 by means of embedding or insertion, so the linkage block 71 can be used as a connecting part between the striking rod 72 and the rotating shaft assembly 3.

[0082] The striking bar 72 can be made of materials with a certain degree of hardness and flexibility, such as rubber or silicone.

[0083] The end of the striking rod 72 furthest from the linkage block 71 strikes the connecting block 53 of the screen structure 5 during the rotation of the rotating shaft assembly 3 (see...). Figure 4 and Figure 5 (as shown) or screen body 51. The linkage block 71 and the striking rod 72 can be located in the area between the two support plates 11.

[0084] In this optional embodiment, during the rotation of the drive shaft assembly 3, the drive component 2 drives the striking component 7 to rotate, causing the linkage block 71 to drive the striking rod 72 to strike the connecting block 53, generating a vibration effect. Simultaneously, the rotation of the striking rod 72 pushes the connecting block 53, the first slider 131, and the second slider 132 to reciprocate under the action of the return spring 52. This reciprocating movement, combined with the vibration generated by the striking, effectively sieves the soil on the screen body 51. Smaller soil particles fall through the mesh of the screen body 51, while larger microplastic particles remain on the screen body 51. The inclined design of the screen body 51 cleverly utilizes gravity, allowing the microplastics to fall smoothly into the rear storage structure 6, making operation simple and quick.

[0085] The soil turning and microplastic collection device can be used on the following working principle:

[0086] The main structure of the device can be mounted on a manually propelled or movable tool. When operation is required, the drive mechanism 2 is activated, driving the drive rod 31 to rotate. The drive rod 31, through the connecting plate 411, drives the soil-turning shovel 412 to rotate in a circular motion. The through-hole structure 4121 on the soil-turning shovel 412 reduces the resistance to the turning motion, preventing the soil from being too hard and damaging the drive mechanism 2. When the soil-turning shovel 412 rotates in a circular motion, it scoops up soil. Due to the soft support of the connecting plate 411 and the buffer spring 33, the soil scooped up by the soil-turning shovel 412 will detach from the soil-turning shovel 412 under the action of centrifugal force and be thrown onto the screen body 51. At this time, the linkage block 71 will drive the striking rod 72 to strike the connecting block 53, generating vibration. The rotation will push the connecting block 53. At this time, the first slider 131 will drive the return spring 52 to slide away from the striking rod 72, and the second slider 132 above will drive the return spring 52 to slide downward. When the striking rod 72 moves away from the connecting block 53 during rotation, the screen body 51 will drive the connecting block 53 to reset under the rebound force of the return spring 52. This reciprocating movement, combined with the vibration generated by the striking, causes soil particles in the soil to fall down from the mesh of the screen body 51. Microplastic particles can temporarily stay on the screen body 51. The inclined design of the screen body 51 and the reciprocating force of the screen body 51 can cause the microplastic particles to fall into the storage structure 6 placed behind the screen body 51 under the action of gravity. The operation is convenient and quick.

[0087] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
