Description

Technical Field

[0001] This utility model relates to the field of road construction technology, specifically to a road solidified soil screening device. Background Technology

[0002] Road stabilized soil is mainly used in road and infrastructure construction. Stabilized soil improves the strength and stability of the soil by adding stabilizing agents (such as cement, lime, industrial waste, etc.), thereby strengthening the roadbed and enhancing its bearing capacity. It can be used as a road base material to replace traditional asphalt concrete or cement concrete. Especially when the budget is limited or the construction conditions are restricted, it is an economical, environmentally friendly and efficient building material, and is widely used in the construction of various roads and infrastructure.

[0003] Chinese Patent Publication No. CN220425919U, entitled "Road Solidification Soil Screening Device," includes a support body, a screening platform mounted on the support body, a tray positioned below the screening platform and connected to the support body, and a vibration device connected to the screening platform. The screening platform is inclined, with the inclination direction including a first inclination direction along the length of the screening platform and a second inclination direction along the width of the screening platform. The bottom surface of the screening platform is a first screen. Using this road solidification soil screening device, topsoil can be excavated at the construction site and screened to separate soil and rock. The soil can be directly solidified, while the rock can be crushed and used.

[0004] The shortcomings of the above solution are: the above solution uses a single-layer vibrating screen, which can only complete one level of screening at a time. Therefore, for materials that require multi-stage screening, the operation needs to be repeated many times, resulting in low overall processing capacity. During the screening process, the material is prone to accumulate on the screen surface, forming the so-called "material arch" phenomenon, which will hinder the normal flow of the material and reduce screening efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a road solidified soil screening device to solve the technical problems of existing single-layer vibrating screening equipment, which can only complete one level of screening at a time, has a low overall processing capacity, and the material tends to accumulate on the screen surface during the screening process, forming the so-called "material arch" phenomenon, which hinders the normal flow of material and reduces screening efficiency.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A road solidified soil screening device, including a mounting frame;

[0008] Multiple sets of screen boxes are arranged above the mounting frame. Each set of screen boxes is connected by welding. A screen mesh is connected to the bottom of each set of screen boxes. A disassembly mechanism is connected between the screen mesh and the screen box. A discharge port is opened on the side wall of each set of screen boxes. A discharge hopper is connected to the end of the discharge port away from the screen mesh. A receiving bucket is provided at the end of the discharge hopper away from the screen box.

[0009] Multiple sets of springs are connected between the mounting frame and the bottom screen box. Vibration motor one and vibration motor two are connected between the mounting frame and the screen box. A guide plate is provided between each set of screen boxes and the screen mesh. The guide plate is set against the side wall of the screen box. Multiple guide plates are provided. Each guide plate is set against the screen mesh. A bearing is connected to each set of screen mesh. A rotating shaft is rotatably connected in each bearing. A handle is connected to the end of the rotating shaft. The end of the guide plate away from the screen box is fixedly connected to the rotating shaft.

[0010] As a further embodiment of this utility model, the aperture of each layer of the screen decreases progressively from top to bottom.

[0011] As a further embodiment of this utility model: the disassembly mechanism includes two mounting plates, a reserved hole is provided on the side of the screen box, the mounting plate is set at the bottom of the screen box through the reserved hole, a connecting block is fixedly connected between the two connecting heads of the two mounting plates, a connecting bolt can be detachably connected to each set of connecting blocks, and multiple support blocks are connected to the bottom of the mounting plate.

[0012] As a further embodiment of this utility model, both mounting plates are semi-circular ring structures.

[0013] As a further embodiment of this utility model, the support block has a semi-circular structure.

[0014] As a further embodiment of this utility model: the first vibration motor and the second vibration motor are symmetrically installed on both sides of the screen box, and the two motors rotate in opposite directions to generate linear vibration.

[0015] As a further embodiment of this utility model: the axes of the first and second vibration motors form an acute angle with the screen plane.

[0016] As a further embodiment of this utility model: the guide plate is connected to the rotating shaft via a bearing, and rotating the handle can drive the guide plate to move on the screen.

[0017] As a further embodiment of this utility model: a sealing plate is connected between the discharge port and the side wall of the screen box, and the opening and closing of the discharge port is controlled by the sealing plate, which is a sliding structure.

[0018] As a further embodiment of this utility model: the discharge hopper has a funnel-shaped structure, with its outlet directly connected to the receiving bucket, and the bottom of the receiving bucket is equipped with casters.

[0019] The beneficial effects of this utility model are:

[0020] 1. In this utility model, vibrating motor one and vibrating motor two are symmetrically installed on both sides of the screen box. The two motors generate synchronous excitation force by rotating in opposite directions. The horizontal component of the vibration force pushes the material towards the discharge port, while the vertical component throws and screens the material, forming a stable linear vibration trajectory. This ensures both uniform material dispersion and directional conveying. The multi-layer screens are arranged with progressively smaller apertures from top to bottom. Large particles are retained on the top layer and discharged from the middle discharge port into the upper discharge hopper. Medium particles pass through the upper screen and are intercepted by the middle screen, then discharged into the middle discharge hopper. Fine particles finally fall to the bottom and are collected through the bottom discharge hopper. The material can be efficiently graded and collected, improving the overall production efficiency of the screening process.

[0021] 2. This utility model drives the rotating shaft by rotating the handle, which in turn moves the guide plate against the screen to clear clogged particles in real time. The screen is fixed by a semi-circular mounting plate, and can be removed simply by unplugging the connecting bolts. The sliding sealing plate can open and close each discharge port individually to selectively collect materials of different particle sizes. By rotating the handle to drive the rotating shaft, the guide plate can be moved to clear clogged particles on the screen in real time, keeping the screen unobstructed, thereby improving screening efficiency and enhancing the continuity and stability of the production line.

[0030] like Figures 1-5 As shown, a road solidified soil screening device includes a mounting frame 1. Multiple sets of screen boxes 17 are arranged above the mounting frame 1. Each set of screen boxes 17 is connected by welding. A screen mesh 10 is connected to the bottom of each set of screen boxes 17. The aperture of each layer of the screen mesh 10 decreases progressively from top to bottom. A disassembly mechanism is connected between the screen mesh 10 and the screen box 17. The disassembly mechanism includes two mounting plates 14, both of which are semi-circular ring structures. A reserved hole is provided on the side of the screen box 17. The mounting plates 14 are positioned at the bottom of the screen box 17 through the reserved hole. A connecting block 15 is fixedly connected between the two connecting heads of the two mounting plates 14. A connecting bolt 16 is detachably connected to each set of connecting blocks 15. Multiple support blocks 18, which are semi-circular structures, are connected to the bottom of the mounting plates 14.

[0031] Multiple sets of springs 11 are connected between the mounting frame 1 and the bottom screen box 17. Vibration motor 12 and vibration motor 2 13 are connected between the mounting frame 1 and the screen box 17. Vibration motor 12 and vibration motor 2 13 are symmetrically installed on both sides of the screen box 17, and the two motors rotate in opposite directions to generate linear vibration. The axes of vibration motor 12 and vibration motor 2 13 form an acute angle with the plane of the screen 10.

[0032] Each set of screen boxes 17 and screen mesh 10 is provided with a guide plate 6. The guide plate 6 is set against the side wall of the screen box 17. Multiple guide plates 6 are provided, and each guide plate 6 is set against the screen mesh 10. Each set of screen mesh 10 is connected to a bearing 7. Each bearing 7 is rotatably connected to a rotating shaft 8. The end of the rotating shaft 8 is connected to a handle 9. The end of the guide plate 6 away from the screen box 17 is fixedly connected to the rotating shaft 8. The guide plate 6 is connected to the rotating shaft 8 through the bearing 7. Rotating the handle 9 can drive the guide plate 6 to move on the screen mesh 10.

[0033] Each set of screen boxes 17 has a discharge port 4 on its side wall. A sealing plate 5 is connected between the discharge port 4 and the side wall of the screen box 17. The discharge port 4 is opened and closed by the sealing plate 5. The sealing plate 5 is a sliding structure.

The discharge hopper 2 is a funnel-shaped structure. Its outlet is directly connected to the receiving bucket 3. The bottom of the receiving bucket 3 is provided with casters.

[0034] The working principle of this utility model is as follows: This device achieves efficient screening of solidified soil through the synergistic effect of mechanical vibration and graded screening. Vibration motor 12 and vibration motor 13 are symmetrically installed on both sides of the screen box 17. The two motors generate synchronous excitation force by rotating in opposite directions. The motor axis forms an acute angle with the plane of the screen 10, so that the horizontal component of the vibration force pushes the material towards the discharge port 4, and the vertical component realizes the throwing and screening of the material, forming a stable linear vibration trajectory, which ensures both uniform material dispersion and directional conveying. The multi-layer screen 10 is arranged with the aperture decreasing from top to bottom. Large particles are retained on the top layer and discharged from the middle discharge port 4 into the upper discharge hopper 2. Medium particles pass through the upper screen 10, are intercepted by the middle screen 10, and are discharged through the discharge port 4 into the middle discharge hopper 2. Fine particles finally fall to the bottom layer and are collected through the bottom discharge hopper 2.

[0035] The rotating shaft 8 is driven by rotating the handle 9, which in turn drives the guide plate 6 to move in contact with the screen 10, clearing blockage particles in real time. The screen 10 is fixed by the semi-circular mounting plate 14, and the screen 10 can be removed by simply removing the connecting bolts 16. The sliding sealing plate 5 can open and close each discharge port 4 individually to achieve selective collection of materials of different particle sizes. The funnel-shaped discharge hopper 2 is matched with the receiving bucket 3 with universal wheels to facilitate the rapid transfer of screened products.

[0036] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
