Technical Field

[0001] This utility model relates to the field of soil screening technology, and in particular to a soil screening device for soil remediation. Background Technology

[0002] Currently, before treating contaminated soil, the crushed and impurity-removed soil is placed in a screening device for screening. This allows workers to perform multi-stage screening, enabling detailed classification of the soil and separate processing of soil particles of different sizes. This not only improves the efficiency of remediation but also allows for better implementation of site-specific remediation measures.

[0003] Among them, a search revealed Chinese patent CN223209920U, which discloses a grading and screening device for soil testing. In the application of the above patent's technical solution, when the screen frame slides out of the screen box, the soil inside the screen frame is prone to fall from the screen at the bottom, which is inconvenient for operators. Therefore, in order to better realize the function of soil removal after screening, promote the technological progress of the industry, and improve the core technology competitiveness, this application proposes a new implementation scheme that is different from the structure of the screening device in the prior art. Utility Model Content

[0004] The purpose of this invention is to solve the problem that soil in the sieve frame of existing screening devices easily falls from the bottom screen, and to propose a soil screening device for soil treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A soil screening device for soil remediation includes a housing. Multiple sets of supporting components are provided on one side of the housing. A screening component is located inside the housing. Each supporting component includes a guide cylinder welded to one side of the housing and communicating with it. A carrying box is slidably inserted into one end of the guide cylinder. The screening component includes a rotating shaft, which is rotatably mounted between the inner walls of both sides of the housing via an interlocking bearing. A rotating plate is fixedly connected to the outer wall of the rotating shaft. A material inlet is provided on the rotating plate, and a screen is engaged within the material inlet. The carrying box can be moved below the screen.

[0006] Furthermore, a handle is fixedly connected to one side of the outer wall of the carrier box, and an anti-slip sleeve is fitted onto the outer wall of the handle.

[0007] Furthermore, the carrier box has two side holes on one side, and two insertion screws are inserted into one side of the guide cylinder, with one end of the insertion screws threaded into the side holes.

[0008] Furthermore, a side plate is fixedly connected to one side of the outer wall of the housing, a drive motor is fixedly connected to one side of the side plate, a rotating rod is keyed to the output end of the drive motor, a plurality of second bevel gears are keyed to the outer wall of the rotating rod, a plurality of support blocks are fixedly connected to one side of the side plate, and the rotating rod passes through the support blocks.

[0009] Furthermore, a first bevel gear is keyed to one end of the rotating shaft, and the first bevel gear meshes with a second bevel gear.

[0010] Furthermore, a plurality of sealing doors are snapped onto one side of the housing.

[0011] Furthermore, a storage box is fixedly connected to the top outer wall of the housing, the top of the storage box is provided with a box cover, the top of the housing is provided with a discharge port, and a vibration motor is fixedly connected to one side outer wall of the housing.

[0012] Furthermore, a support cylinder is fixedly connected to one side of the outer wall of the housing, an electric push rod is fixedly connected to one side of the support cylinder, and a baffle is fixedly connected to one end of the electric push rod. The baffle moves inside the support cylinder and can be inserted into the feed port.

[0013] The beneficial effects of this utility model are as follows: 1. By moving the carrier box below the screen, and then tilting the screen by driving the motor, the first bevel gear, and the second bevel gear, different soil particles fall into the carrier box for collection, thus avoiding mixing.

[0014] 2. The vibrating motor drives the housing to vibrate, which in turn drives the screen to vibrate, thereby accelerating the screening and feeding of soil, making it convenient and fast.

[0015] 3. By placing the storage box on top of the shell and then retracting the baffle into the support cylinder by the retraction of the electric push rod, the discharge port can be opened, thus ensuring that the soil is screened in a closed environment and preventing dust from flying.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figures 1-6 A soil screening device for soil remediation includes a housing 1 and a control panel. Multiple sets of bearing components 2 are provided on one side of the housing 1. Screening components 3 are provided inside the housing 1. The bearing components 2 include a guide cylinder 201, which is welded to one side of the housing 1 and communicates with the housing 1. A bearing box 202 is slidably inserted into one end of the guide cylinder 201, and the guide cylinder 201 guides the movement of the bearing box 202. The screening assembly 3 includes a rotating shaft 301, which is rotatably mounted between the inner walls of both sides of the housing 1 via a connecting bearing. A rotating plate 302 is fixed to the outer wall of the rotating shaft 301 by bolts. A feed inlet 303 is provided on the rotating plate 302, and a screen 304 is clamped inside the feed inlet 303. From top to bottom, the first layer of screen 304 has a mesh diameter of more than 20 mm and is used for gravel separation. The second layer of screen 304 has a mesh diameter of 5-10 mm and is used for coarse sand separation. The third layer of screen 304 has a mesh diameter of 1-2 mm and is used for fine sand separation. The fourth layer of screen 304 has a mesh diameter of 0.25-0.5 mm and is used for powder and particle separation. The carrier box 202 can be moved below the screen 304.

[0020] A handle 205 is fixed to one side of the outer wall of the carrier box 202 by bolts. The outer wall of the handle 205 is fitted with an anti-slip sleeve, which facilitates the operation of the carrier box 202.

[0021] The carrier box 202 has two side holes 203 on one side, and two plug screws 204 are inserted into one side of the guide cylinder 201. One end of the plug screw 204 is threaded into the side hole 203 to fix the carrier box 202 and prevent the carrier box 202 from shifting position.

[0022] A side plate 5 is bolted to one side of the outer wall of the housing 1. A drive motor 6 is bolted to one side of the side plate 5. A rotating rod 7 is keyed to the output end of the drive motor 6. Multiple second bevel gears 8 are keyed to the outer wall of the rotating rod 7. Multiple support blocks 9 are welded to one side of the side plate 5. The rotating rod 7 passes through the support blocks 9. A first bevel gear 305 is keyed to one end of the rotating shaft 301. The first bevel gear 305 meshes with the second bevel gear 8. Driven by the drive motor 6, the rotating rod 7 rotates, thereby driving the second bevel gear 8 to rotate. Then, under the action of the second bevel gear 8 meshing with the first bevel gear 305, the rotating shaft 301 rotates, thereby driving the screen 304 to rotate. This causes the screen 304 to tilt so that soil particles of different sizes fall into the carrier box 202 for collection.

[0023] Multiple sealing doors 4 are snapped onto one side of the housing 1 to facilitate the cleaning and maintenance of the screen 304.

[0024] The top outer wall of the shell 1 is fixed with a storage box 10 by bolts. The top of the storage box 10 is provided with a box cover. The top of the shell 1 is provided with a discharge port, and the soil falls into the shell 1 from the discharge port. A vibration motor 14 is fixed to one side of the outer wall of the housing 1 by bolts. The vibration motor 14 drives the housing 1 to vibrate, which in turn drives the screen 304 to vibrate, thereby accelerating the screening and feeding of soil.

[0025] A support cylinder 11 is fixed to one side of the outer wall of the housing 1 by bolts. An electric push rod 13 is fixed to one side of the support cylinder 11 by bolts. A baffle 12 is fixed to one end of the electric push rod 13 by bolts. The baffle 12 moves inside the support cylinder 11 and can be inserted into the feed port to prevent dust from flying during soil screening and thus avoid environmental pollution.

[0026] The control panel is connected to the drive motor 6 and the electric push rod 13 via wires.

[0027] The working principle of this embodiment is as follows: In the initial state, the baffle 12 is inserted into the feed port. Then, the screen 304 is placed horizontally, the carrier box 202 is located in the guide cylinder 201, and the lowest carrier box 202 is moved to the bottom of the fourth screen 304 and fixed with the plug screw 204. First, open the box cover and put the crushed and impurity-removed soil into the storage box 10. Then, start the electric push rod 13 through the control panel. As the electric push rod 13 retracts, the baffle 12 is retracted into the support cylinder 11, thereby opening the discharge port. Then, the soil falls onto the first screen 304, and the gravel is trapped on the first screen 304, thus screening out the gravel. The other soil falls onto the second screen 304, and the coarse sand grade soil is trapped on the second screen 304, thus screening out the coarse sand grade soil. The remaining soil falls onto the third screen 304, and the fine sand grade soil is trapped on the third screen 304, thus screening out the fine sand grade soil. The remaining soil falls onto the fourth screen 304, thus screening out the silt grade soil. Then, the clay grade particles fall onto the carrier box 202 below for collection. During the screening process, the vibrating motor 14 drives the shell 1 to vibrate, thereby driving the screen 304 to vibrate, thus accelerating the screening of the soil. After screening, the baffle 12 is inserted into the discharge port by the electric push rod 13 to seal the housing 1. Then, the plug screw 204 is pulled out, and the other carrier box 202 is pushed under the screen 304 and fixed with the plug screw 204. Next, the drive motor 6 is started through the control panel. Under the drive of the drive motor 6, the rotating rod 7 rotates, thereby driving the second bevel gear 8 to rotate. Then, under the action of the second bevel gear 8 meshing with the first bevel gear 305, the rotating shaft 301 rotates, thereby driving the screen 304 to rotate, thus causing the screen 304 to tilt so that the soil falls into the carrier box 202 for collection. During this process, the soil discharge is accelerated by the vibration motor 14.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
