Specific embodiments

[0039] Next, in conjunction with the accompanying drawings of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0040] Embodiment:

[0041] Referring to Figure 1 - Figure 3 and Figure 6 - Figure 17 An embodiment provided by the present utility model: A mobile soil washing and scrubbing vehicle, including a vehicle body 1, which is divided into a front part, a middle part and a rear part of the vehicle. The front part of the vehicle includes a feeding bin 2, a pre-screening device 3, and a belt conveyor 1 4; a belt conveyor 2 5, a stirring and feeding machine 6, a circulating water tank 7, a hydraulic pump station 8, an electrical control cabinet 15, and a filter tank 17 are arranged in the middle part of the vehicle; a cylindrical soil scrubbing machine 9, a splash-proof device 10, a dewatering screen 11, a belt conveyor 3 12, a mud buffer hopper 13, a mortar pump 14, and a chassis assembly 16 are arranged in the rear part of the vehicle; each component in the front part of the vehicle, each component in the middle part of the vehicle, and each component in the rear part of the vehicle are all centrally installed on the chassis assembly and centrally constitute an overall system.

[0042] Among them, a feeding bin 2 is fixedly connected to the top right side of the vehicle body 1. A pre-screening device 3 is installed at the bottom of the feeding bin 2. A belt conveyor 1 4 is installed on the top right side of the vehicle body 1. A belt conveyor 2 5 is installed on the bottom left side of the feeding bin 2. A stirring and feeding machine 6 is installed in the middle of the top of the vehicle body 1. A circulating water tank 7 is installed on the bottom right side of the vehicle body 1. An inspection manhole is opened in the upper part of the circulating water tank 7, and a submerged pump is installed inside. A guardrail is installed on the top edge of the circulating water tank 7, and a ladder is installed on the side.

[0043] Specifically, the vehicle body 1 provides a support and protection structure for the entire mobile soil washing and scrubbing vehicle. The feeding bin 2 is used to store the soil or other raw materials to be processed to ensure sufficient raw material supply during continuous operation. The pre-screening device 3 performs preliminary screening on the incoming materials to remove larger sundries or particles and prepare for subsequent processing. The pre-screening device 3 is provided with a bar assembly 19 and a buffer bottom plate 20. The bar assembly 19 is installed inside the pre-screening device 3 and is arranged in a stepped manner. The bar assembly 19 is more conducive to material flow and separation compared with the traditional screen mesh. To further avoid blockage of the bar assembly 19, the buffer bottom plate 20 is arranged above the bar assembly 19. The buffer bottom plate 20 is used to buffer the soil feed to prevent bulk materials from directly contacting the bar assembly 19. The pre-screening device 3 performs preliminary screening on the raw materials to remove larger sundries or particles and prepare for subsequent processing;

[0044] In addition, the first belt conveyor 4 is provided with a folding device 21. The first belt conveyor 4 is mainly used for transporting materials with a size of more than 100 mm and entering the next disposal link. The folding device 21 of the first belt conveyor 4 adopts a hydraulic pushing structure when the belt is folded, which is beneficial to the quick implementation of the folding and stretching functions. At the same time, the folding design can effectively save the vehicle body space, shorten the transportation size, make the equipment more centralized, and is beneficial to rapid transportation. The first belt conveyor 4 has the following functions and advantages in terms of structural design: 1. It can transport materials with a size of more than 100 mm. The belt adopts a folding design, which ensures the working distance using limited space. 2. When the belt is folded, it adopts a hydraulic pushing structure, and the folding and stretching are convenient and fast. 3. The one-time formed annular belt is durable; it prevents the cleaning device from damaging the joint structure. 4. The cleaning device adopts a torsion spring form, with a more compact structure, convenient maintenance and fewer failures. 5. The folding design effectively saves the vehicle body space, reduces the manufacturing cost, and at the same time shortens the transportation size. 6. The tensioning device can adjust the belt tension and the cleaning device pressure at the same time. Both the first belt conveyor 4 and the third belt conveyor 12 are provided with hydraulic folding mechanisms, which can adjust the height or angle of the conveyor;

[0045] Combined with Figure 10 , the blades of the stirring feeder 6 of the stirring feeder 6 are arranged in a bidirectional spiral manner, and polyurethane scrapers are installed on the blades. The reverse spiral blades and the forward spiral blades work together to ensure uniform mixing of the soil during the stirring process. A spray water pipe is arranged on the upper part of the stirring feeder 6. The stirring feeder 6 is used for mixing and feeding to ensure that the soil or materials can effectively enter, be stirred and transmitted, so that the soil and the leaching solution are fully mixed. An inspection manhole is opened at the top of the circulation water tank 7, which is convenient for the operator to perform maintenance, cleaning or maintenance on the inside of the water tank. The built-in submersible pump provides water source for scrubbing. By setting a guardrail, it can prevent the operator from accidentally falling from the circulation water tank 7 during work. By setting a ladder, it is convenient for the operator to enter the equipment for maintenance and cleaning;

[0046] The working principle of the present utility model is that the chassis assembly 16 is an effective integral structure, which is the carrier for connecting various modules. It can effectively form an integrated skid-mounted structure for various module devices, facilitating the collaborative operation between modules and the rapid transfer of the overall equipment after the start and end of work. The feeding bin 2 is a soil feeding temporary storage and feeding bin. A rigid anti-collision beam design is adopted at the feeding port of the feeding bin 2 to prevent the feeding equipment from directly colliding with the bin body. The bin body structure of the feeding bin 2 adopts a regular quadrangular pyramid cone design with an adjustable inclination angle to solve the problem of material jamming and storage. A pre-screening device 3 is provided below the feeding bin 2. The pre-screening device 3 is used to screen construction waste, bricks, stones, gravel and other substances with a soil particle size > 100 mm. The structure design of the pre-screening device 3 adopts side plate vibration motors, which is more conducive to maintenance and power saving functions. The screen bar angle of the pre-screening device 3 can be adjusted according to different situations of the material particle size and viscosity. After the soil is screened, the soil material > 100 mm is output from the discharge port through the belt conveyor 1 and regularly removed. The belt of the belt conveyor 1 adopts a folding design method, which effectively saves the working space and shortens the working distance, and adopts a hydraulic jacking structure to realize the convenient and fast folding and extension of the equipment. A five-layer core wear-resistant rubber sealing strip is used for sealing at the discharge port of the pre-screening device 3, which fits tightly with the belt conveyor and is not easy to spill materials. After the soil is screened, the soil with a particle size ≤ 100 mm enters the belt conveyor 2. The belt conveyor 2 conveys the soil with a particle size ≤ 100 mm to the mixing feeder 6. A weighing and sensing monitor is installed below the belt conveyor 2 to monitor the material flow rate in real time. The mixing feeder 6 is used for mixing and continuously feeding the soil with a particle size ≤ 100 mm. The mixing feeder 6 adopts a positive and negative spiral method, and the mixing direction is opposite, from both sides to the middle, which can make the mixing more uniform and prevent material blockage. The circulating water tank 7 stores the recycled water treated by the production line and can timely supplement clean water for the supply of the production water for rinsing the production line. The circulating water tank 7 is a large-capacity integrated water storage device with an upper and lower two-layer structure and a self-provided height difference, which is convenient for the self-flow of the circulating water in the vehicle. An electrical control cabinet 15 is installed on one side of the water tank to facilitate the cooling and temperature reduction of the circuit.

[0047] Refer to Figure 1 - Figure 3 、 Figures 11 - 16 At the middle part of the bottom end of the vehicle body 1, a hydraulic pump station 8 is installed. At the left side of the top end of the vehicle body 1, a cylindrical soil scrubbing machine 9 is installed. The cylindrical soil scrubbing machine 9 is driven by two motors. The cylindrical soil scrubbing machine 9 includes a transmission device 22, a carrier roller assembly 23, a retaining roller assembly 24, a feeding device 25, a spiral discharging device 26, a rotating cylinder 27, and a rubber friction strip 28.

[0048] The cylindrical soil scrubbing machine 9 is mainly used for scrubbing materials. The transmission device 22, the towing wheel assembly 23, and the retaining wheel assembly 24 are located on the same straight line, changing the traditional vertical composition structure, which can meet different operating speed requirements, accelerate the stable operation of the frequency conversion node, and is beneficial to reducing the equipment composition space.

[0049] A dehydration screen 11 is installed on the left side of the top end of the vehicle body 1. An anti-splash device 10 is installed at the material falling position between the cylindrical soil scrubbing machine 9 and the dehydration screen 11. The anti-splash device 10 includes an anti-splash rubber-coated canvas cover and an anti-splash hanging rack. A belt conveyor three 12 is installed at the left end of the vehicle body 1. A slurry buffer hopper 13 is installed at the left side of the bottom end of the vehicle body 1. A mortar pump 14 is installed at the left side of the bottom end of the vehicle body 1.

[0050] During operation, the hydraulic pump station 8 provides hydraulic power for the folding of the belt conveyor one 4, the folding of the belt conveyor three 12, the lifting of the chassis assembly 16, and the angle adjustment of the pre-screening device 3. The cylindrical soil scrubbing machine 9 is used to scrub the soil, remove pollutants in the soil, and repair the soil to make it clean soil. Through the combined action of the pre-screening device 3 and the stirring feeder 6 of the present utility model, the cylindrical soil scrubbing machine 9 provides qualified materials to more efficiently remove pollutants in the soil and achieve the purpose of soil repair. The working principle of the cylindrical soil scrubbing machine 9 is that when the towing wheel assembly 23 rotates, under the action of friction, the towing wheel assembly 23 drives the rotating cylinder 27 to make a rotational motion. Materials are fed into the rotating cylinder 27 from the feeding device 25. After being driven by the rubber friction strips 28 inside the rotating cylinder 27, the materials are discharged by the spiral discharging device 26 after being lifted, rubbed, and thrown. There is a horizontal height difference between the feeding device 25 and the spiral discharging device 26, so the materials will overflow from the spiral discharging device 26.

[0051] The cylindrical soil scrubber 9 is driven by dual motors, running smoothly with low noise; the feeding device 25 is designed with a conical structure for smoother feeding. High-elastic, wear-resistant, and corrosion-resistant lining plates and pressing strips are designed inside the rotating cylinder 27 to clean the attachments on the surface of sand and gravel. The cleaning effect on especially difficult-to-clean materials is obvious. The rotation of the drum causes the materials to tumble and fall along the cylinder wall. The heavier the materials, the more thoroughly the surface is scrubbed. At the same time, a universal joint coupling is arranged between the two idlers in the transmission device, which can effectively prevent the problem of misalignment during the installation of the two idlers. Rubber coating is provided on the idler wheels to increase the friction force, prevent slipping during the process of the idler wheels driving the cylinder to rotate, improve the transmission efficiency, and reduce the noise generated during operation. The cylindrical soil scrubber 9 adopts dual-motor drive and rubber lining plate design to improve the stability, efficiency, and service life of the equipment, while ensuring effective stirring, crushing, and mixing of the materials to improve the disposal efficiency of contaminated soil. The anti-splash hanger of the anti-splash device 10 is a circular-arch steel structure part, spanning both sides of the vehicle frame at both ends, playing a role in connection and reinforcement. The belt conveyor III 12 is provided with a hydraulic folding mechanism to adjust the height or angle of the conveyor. The mud buffer hopper 13 buffers the treated mud for subsequent treatment or disposal. The mortar pump 14 is used to transport materials such as treated soil or mud to the required positions or for further treatment;

[0052] Among them, as Figure 15 and Figure 16 The dewatering screen 11 mainly conducts cleaning, dewatering, and grading of sand and gravel, and can effectively recover a large amount of fine sand lost by sand washers in the traditional sand-making industry. While improving economic benefits, it reduces the treatment cost of tailings and the environmental pollution and damage caused by the lost fine sand. The equipment has a reasonable structure, unique and novel design, and uses dual vibration motors as the excitation source to make the materials perform a throwing motion to achieve the screening treatment purpose.

[0053] The rear side plate 29 of the screen body of the dewatering screen 11 is improved, and a recessed feeding port is arranged above the rear side plate 29 of the screen body to match the front-end scrubbing agent feeding link, effectively reducing the distance between the discharge of the cylindrical soil scrubber 9 and the dewatering screen 11, facilitating the smooth operation of material transportation, reducing the overall height of the equipment, and being convenient for centralized skid-mounted transportation.

[0054] During the working process, the slurry aggregate is discharged from the discharging device 26 of the cylindrical soil scrubber 9 and falls onto the upper part of the sieve plate. The materials on the sieve are large particle aggregates, and the materials under the sieve are slurry and fine mud and sand. The large particle aggregates are discharged through the discharge port. The slurry and fine mud and sand fall into the slurry buffer bin and then enter the fine sand selection equipment through the slurry pump 14. The dewatering screen 11 adopts the double vibration motor self-synchronization technology, a general-purpose eccentric block, and an adjustable amplitude vibrator. Two independent vibration motors operate in synchronous reverse rotation. The centrifugal forces generated by the two groups of eccentric blocks are superimposed in the component force along the vibration direction, and the reverse centrifugal forces cancel each other out, thus forming a single exciting force along the vibration direction, making the sieve box perform reciprocating linear motion. The equipment uses a highly elastic and wear-resistant polyurethane sieve mesh. Compared with the conventional rubber mesh sieve, polyurethane itself has a very high elastic modulus, high strength to absorb impact force, and high wear resistance, so it has a very high tensile strength. This module uses elastic support parts as elastic elements, and the effect is the same as that of the elastic support parts in the pre-screening device three in the previous text. Compared with the traditional screening machine, the connection between the motor cross beam, support beam and sieve box of this dewatering screen 11 is connected by high-strength bolts, without welding deformation and stress, avoiding the deformation and tearing of the box body caused by welding stress during the operation of the traditional screening machine;

[0055] In addition, the hydraulic pump station 8 is the output center for converting electrical energy into hydraulic mechanical energy. The hydraulic pump station 8 can simultaneously realize the automatic lifting of the vehicle body, the opening and closing of the conveyor, and can realize the rapid installation and disassembly of the flushing production line, which is conducive to rapid transfer. The cylindrical soil scrubber 9 realizes the functions of fully mixing and stirring the soil and the flushing liquid. The rotating force of the cylindrical soil scrubber 9 is likely to splash out the slurry, polluting the equipment and personnel. The anti-splash device 10 can protect the vehicle body 1 and the on-site working environment in all directions, which is conducive to avoiding and reducing secondary environmental pollution. The dewatering screen 11 can efficiently separate the soil materials with a particle size greater than 2 mm in the soil. The dewatering screen 11 uses a wear-resistant polyurethane sieve mesh, which has better impact resistance and chemical corrosion resistance, adopts an elastic support function, effectively reduces the working noise, outputs the soil materials with a particle size greater than 2 mm through the belt conveyor three 12, and transports them away in time. The remaining slurry falls freely to the slurry buffer hopper 13. The belt conveyor three 12 outputs the soil materials with a particle size greater than 2 mm. The belt conveyor three 12 can effectively save the temporary storage space in the workshop and shorten the working distance; The slurry buffer hopper 13 receives the slurry output by the dewatering screen 11. The slurry buffer hopper adopts a hinge support and a special-shaped structure design, which can effectively improve the pumping efficiency, effectively reduce and avoid the phenomenon of siltation and mud blockage, and is internally equipped with a liquid level sensor, which can effectively control the start and stop of the front and rear end equipment. The slurry pump 14 is a submerged built-in pump structure.

[0056] Refer to Figure 2 and Figure 17 As shown in, an electrical control cabinet 15 is installed inside the vehicle body 1, and a chassis assembly 16 is installed at the bottom end of the vehicle body 1. The chassis assembly 16 is provided with a hydraulic lifting device.

[0057] Specifically, the electrical control cabinet 15 is used to centrally control each component of the mobile soil washing and scrubbing vehicle, realizing automated operation and monitoring. The chassis assembly 16 provides the support and running system for the entire vehicle, ensuring the movement and stable operation of the vehicle;

[0058] In addition, the electrical control cabinet 15 controls and monitors the operating conditions of the production line to achieve automatic system operation. The electrical control cabinet 15 is installed on the side of the circulation water tank 7, which is conducive to circuit cooling. The installation height is designed according to the ergonomic principle, facilitating manual control. The chassis assembly 16 is modular and skid-mounted, integrating various components into the total vehicle body 1, enabling modular skid-mounted rapid transfer.

[0059] Referring to Figure 2 、 Figure 4 and Figure 5 As shown in, a filter box 17 is slidably connected inside the circulation water tank 7. A disassembly component 18 is installed outside the filter box 17. The disassembly component 18 includes two limiting slots 1801, which are respectively opened on the left and right sides inside the circulation water tank 7. A spring 1802 is fixedly connected to the inner wall of the limiting slot 1801. The adjacent ends of the two springs 1802 are both fixedly connected with a limiting block 1803. The inside of the limiting slot 1801 is slidably connected to the outside of the limiting block 1803. The adjacent ends of the two limiting blocks 1803 are both fixedly connected with a clamping block 1804. Card slots 1805 are opened on the left and right sides inside the filter box 17. The outside of the clamping block 1804 is engaged with the inside of the card slot 1805. The separated ends of the two limiting blocks 1803 are both fixedly connected with a traction rope 1806. The inside of the circulation water tank 7 is slidably connected to the outside of the traction rope 1806. The adjacent ends of the two traction ropes 1806 are fixedly connected with a rotating rod 1807.

[0060] Specifically, the circulation water tank 7 plays a limiting role on the filter box 17, enabling the filter box 17 to move stably. The limiting slot 1801 and the limiting block 1803 play a fixing role on the spring 1802, enabling the spring 1802 to stably undergo elastic deformation. The limiting slot 1801 plays a limiting role on the limiting block 1803 and the clamping block 1804, ensuring that the limiting block 1803 and the clamping block 1804 do not deviate during movement. Through the engagement of the clamping block 1804 with the card slot 1805, the position of the filter box 17 is fixed. Sealing rings are provided at the connection between the filter box 17 and the circulation water tank 7, preventing water from leaking from their connection. The circulation water tank 7 plays a limiting role on the traction rope 1806 and the rotating rod 1807, enabling the traction rope 1806 to move stably and the rotating rod 1807 to rotate stably.

[0061] The soil filtration data of this mobile soil washing and scrubbing vehicle is as follows:

[0062] The device can operate continuously for 24 hours. Calculated based on a two-shift system with 16 hours of work per day, 640 tons of contaminated soil can be treated daily. With a water-soil ratio of 2:1, considering the recycled water and evaporation of water consumption, 15 tons of fresh water need to be replenished per hour, and 305 tons of water are used per day.

[0063] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
