Description

Technical Field

[0001] This invention relates to the field of construction site dust control technology, and in particular to a spray dust control device for construction sites that can level the land. Background Technology

[0002] Construction sites are large open areas. Activities such as exposed soil, material handling, vehicle movement, and earthmoving operations cause fine particulate matter to float into the air under wind or external forces, forming large amounts of dust. Therefore, systems such as perimeter sprinkler systems, tower crane sprinkler systems, or mist cannons are installed. These systems use high-pressure equipment to atomize water into micron-sized droplets. These water droplets have virtually zero surface tension, allowing them to quickly absorb airborne dust particles, causing them to settle due to their increased weight, thus purifying the air. The fine water mist is more effective at capturing small dust particles, consumes less water, and is less likely to accumulate mud and grime on the ground. Misty cannons, in particular, are characterized by their large atomization volume and can be used in both fixed and mobile forms. They achieve dust suppression through a large number of atomized water droplets, providing rapid dust reduction in construction projects.

[0003] However, existing fog cannons can only suppress dust, but cannot level the road surface. This causes dust to be stirred up when construction vehicles drive by, making it difficult to control dust generation. There is a need to design a spray dust suppression device for construction sites that can level the land and suppress dust generation by leveling the road surface. Summary of the Invention

[0010] According to the technical solution provided in the embodiments of this application, the shock box is provided with a leveling component near the front end of the vehicle board. The leveling component is used to push the soil and gravel to move in a second direction away from the center of the vehicle board.

[0011] According to the technical solution provided in the embodiments of this application, the leveling component includes: A trapezoidal shovel plate, wherein the cross-section of the trapezoidal shovel plate is a right trapezoid, the right-angled side is connected to the shock box, and the top is provided with an installation groove. The installation groove is provided with a ramp block inside, and the ramp block has a first acute angle between the inclined surface and the bottom surface of the trapezoidal shovel plate. The opening of the first acute angle faces the center side of the vehicle plate. A frustum sleeve is rotatably mounted on the central side surface of the shock box away from the vehicle board, and the outer diameter of the frustum sleeve near the end of the shock box is larger than the outer diameter of the other end.

[0012] According to the technical solution provided in the embodiments of this application, the second leveling mechanism further includes a solar panel, which includes a plurality of photovoltaic panels for generating electricity and installed on the top surface of the mounting frame, and a cleaning structure for cleaning the surface of the photovoltaic panels, wherein the cleaning structure is used to wipe the light-receiving surface of the photovoltaic panels.

[0013] According to the technical solution provided in the embodiments of this application, the cleaning structure includes a second acute angle between the photovoltaic panel and the mounting frame, and the opening of the second acute angle faces away from the center of the vehicle panel; The top surface of the photovoltaic panel abuts against a semi-circular wiping pad. The top of the semi-circular wiping pad is detachably installed at the bottom of the connecting rod. The top of the connecting rod is provided with several sliding rods extending toward the center of the vehicle panel. The sliding rods slide through the bottom of the storage compartment away from the end of the connecting rod and are equipped with an end plate. A spring is provided between the end plate and the outer wall of the storage compartment.

[0014] According to the technical solution provided in the embodiments of this application, a rubber damping sleeve is installed inside the first shaft, and the top of the vibration pressure box is connected to the bottom of the mounting frame through a vibration damper.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This invention incorporates a first leveling mechanism and a second leveling mechanism. A pressure roller ring at the rear of the vehicle platform presses the ground firmly, while a vibrating pressure box, driven by a vibrating motor, compacts both sides of the platform. Because the pressure roller ring and the two vibrating pressure boxes are staggered, the road surface is effectively leveled. Furthermore, during the reciprocating movement of the tricycle, airborne dust mixes with water under the action of the mist cannon and falls to the ground. The compaction effect of the pressure roller ring and the vibrating pressure box achieves the goal of leveling the road. This effectively solves the problem that existing mist cannons can only suppress dust but cannot level the road, causing dust to be repeatedly stirred up by construction vehicles, failing to control dust generation. Further, to improve the compaction effect, a first nozzle is added to the front of the pressure roller ring, and a second nozzle is added to the front of the vibrating pressure box. Water spray increases the soil moisture, making the moistened soil easier to deform and bind together, ensuring effective and stable compaction.

[0016] In addition, both the first and second leveling mechanisms can be stored and are easy to clean. The pressure roller ring of the first leveling mechanism moves upward, and then the first motor is started to drive the pressure roller ring to rotate, so that the scraper scrapes off the sticky soil on the surface of the pressure roller ring, so as to avoid the soil sticking and causing the road to be uneven when the pressure roller ring is used next time. The vibration box of the second leveling mechanism swings to a vertical position with the installation frame, so that the bottom surface of the vibration box faces the side, making it easy for the user to use tools to clean the mud sticking to the surface of the vibration box. In this application, the rolling pressing roller rings are distributed in the central area of ​​the vehicle platform, while the vibratory pressing cylinders are distributed on both sides of the vehicle platform. This ensures the stability of the tricycle body during operation and the ease of cleaning. Rolling pressing can improve the pressing effect by utilizing the overall weight of the tricycle body. If vibratory pressing is used, it will cause instability in the tricycle body and make it inconvenient to clean the vibrating surface. Vibratory pressing is symmetrically set on both sides, and the mounting frame is connected to the vehicle body by a hinge to balance the vibration. If rolling pressing is chosen, it will result in insufficient pressing force and poor compaction effect. Furthermore, even if the rolling pressing cylinder is kept vertical, it will be inconvenient for the user to clean. Therefore, the reasonable alternation of the two pressing methods ensures excellent road smoothness.

[0017] In addition, a leveling component is installed, which removes the protruding parts of the road by using a trapezoidal shovel. The shoveled soil will enter the installation groove 45 along the sloping side of the trapezoidal shovel. Finally, with the vibration of the vibration box, the soil will be shaken and sent out along the slope block. Then, the round sleeve will squeeze these sent soil blocks, which will achieve a simple compaction effect. This not only ensures the flatness of the road, but also prevents the soil blocks at the edge of the road from raising dust after compaction. In addition, solar panels are installed, placing photovoltaic panels on the mounting frame to generate electricity through sunlight, achieving energy-saving effects. The mounting frame can also be retracted into the storage compartment, preventing dust accumulation on the surface of the photovoltaic panels due to long-term exposure, thus avoiding a reduction in photovoltaic efficiency. Furthermore, a semi-circular wiping pad, sliding rod, and spring are installed. During the storage of the mounting frame and photovoltaic panels, the semi-circular wiping pad and sliding rod move towards the center of the vehicle platform to wipe the photovoltaic panels before storage. When the mounting frame and photovoltaic panels are released, the semi-circular wiping pad and sliding rod are reset by the spring, resetting the photovoltaic panels before unfolding, achieving a thorough and effective cleaning effect and ensuring the power generation efficiency of the photovoltaic panels.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please refer to Figures 1-14 An embodiment of the present invention provides a dust suppression spraying device for construction sites that can level land, comprising: The three-wheeled vehicle body 1 includes a vehicle board 11 extending along a first direction. The vehicle board 11 has a front and a rear along the first direction, and a fog cannon 14 is provided on the rear of the vehicle board 11. The first leveling mechanism 2 is installed at the rear bottom of the vehicle plate 11, and includes a pressure roller ring 25 that can move in the vertical direction and rotate on its own axis. The axis of the pressure roller ring 25 is in the second direction. Two second leveling mechanisms 3 are respectively installed on both sides of the vehicle panel 11 along the second direction. Each mechanism includes a mounting frame 35 that is hinged to the vehicle panel 11. The bottom end of the mounting frame 35 is provided with a vibration box 37 that can abut against the ground. A vibration motor 38 is installed inside the vibration box 37. The side of the vehicle panel 11 is also provided with a storage compartment 31 that fits with the mounting frame 35. Several second telescopic members 33 are hinged to the top of the storage compartment 31. The other end of each second telescopic member 33 is hinged to the middle of the top of the mounting frame 35. The extension direction of the hinge axis of each second telescopic member 33 and the mounting frame 35 is the first direction. The top of the second telescopic member 33 is hinged to the top of the storage compartment 31 through a first hinge member 32, and the bottom end is connected to the middle of the top of the mounting frame 35 through a second hinge member 34. The mounting frame 35 is hinged to the side end face of the vehicle panel 11 through a third hinge member 314. In addition, the opening of the storage compartment 31 faces away from the center of the vehicle panel 11, and the edge of the opening exceeds the edge of the vehicle panel 11 by a first difference. The first difference matches the thickness of the mounting frame 35, and the outer surface of the mounting frame 35 matches the inner surface of the storage compartment 31. This ensures that the mounting frame 35 can be stably placed inside the storage compartment 31, guaranteeing the storage stability of the mounting frame 35 and the shock-absorbing box 37. The two ends of the first pressure roller ring 25 overlap with the ends of the two vibration pressure boxes 37 respectively.

[0024] The pressure roller ring 25 at the rear of the vehicle platform 11 presses the ground firmly, while the vibration pressure box 37, under the action of the vibration motor 38, compacts both sides of the vehicle platform 11. Because the ends of the pressure roller ring 25 and the two vibration pressure boxes 37 are staggered, the road surface can be fully leveled. As the tricycle body 1 moves back and forth, the dust in the air mixes with water under the action of the fog cannon 14 and falls to the ground. After being pressed and compacted by the pressure roller ring 25 and the vibration pressure box 37, the purpose of leveling the road is achieved. This effectively solves the problem that the existing fog cannon 14 can only suppress dust and cannot level the road, causing dust to be repeatedly raised on the road when engineering vehicles are driving, which cannot suppress dust generation.

[0025] The second telescopic component 33 can be a hydraulic strut, allowing manual pushing of the mounting frame 35 to swing. The self-supporting effect of the hydraulic strut ensures that the mounting frame 35 maintains a fixed angle after swinging. Alternatively, the second telescopic component 33 can be an electric push rod, connected to the power supply of the tricycle body 1 via an electric wire, with a switch installed on the wire for easy operation. (Reference) Figure 9 The second telescopic component 33 can be selected in a multi-section telescopic mode to ensure that the second telescopic component 33 can be completely retracted into the storage compartment 31 after retraction. Based on this, the first hinge component 32 and the second hinge component 34 are common hinge structures, and the ZY-HKJ cross-shaft type high-precision Hooke hinge universal joint can be selected.

[0026] In some embodiments, the first leveling mechanism 2 includes a first shaft 22 that passes through the inside of the pressure roller ring 25 and is rotatable. Both ends of the first shaft 22 are equipped with first telescopic members 21. Both first telescopic members 21 are installed at the rear of the vehicle plate 11. Side guard rings 23 are sleeved at both ends of the first shaft 22 at the position between the first telescopic members 21 and the pressure roller ring 25. One end face of the side guard ring 23 is in contact with the side surface of the pressure roller ring 25. The bottom of the car plate 11 is also provided with a scraper 27 extending in the second direction, and the bottom end of the scraper 27 can abut against the outer surface of the pressure roller ring 25; a drive unit is also provided below the tail of the car plate 11, which is used to drive the pressure roller ring 25 to rotate.

[0027] The first telescopic member 21 extends downward, driving the first shaft 22 to move downward and squeeze the bottom surface of the inner wall of the pressure roller ring 25, so that the pressure roller ring 25 is pressed tightly onto the ground, achieving the effect of pressing the ground. When pressing is not required, the first telescopic member 21 retracts, driving the first shaft 22 and the pressure roller ring 25 to move upward until the scraper 27 is in contact with the outer surface of the pressure roller ring 25. Then, the drive unit drives the pressure roller ring 25 to rotate, so that the scraper 27 scrapes off the mud and debris on the surface of the pressure roller ring 25, ensuring a stable pressing effect next time.

[0028] The first telescopic component 21 can be selected from commonly used pneumatic cylinders, electric cylinders, or hydraulic cylinders. Considering vehicle use, to reduce the need for additional hydraulic and pneumatic systems, the first telescopic component 21 and the second telescopic component 33 can be selected from long-stroke multi-section telescopic servo electric cylinders. The servo electric cylinder is connected to the power supply of the tricycle body 1 through a wire, and a switch is installed on the wire for easy operation by the operator.

[0029] Optionally, the rear of the vehicle plate 11 is provided with a U-shaped plate 12, and the top of the U-shaped plate 12 is provided with a first support frame 13. The water pump 15 is installed in the middle of the first support frame 13, and the fog cannon 14 is installed on the top of the first support frame 13. Preferably, the drive unit includes a second shaft 28 installed between the two ends of the U-shaped plate 12. Friction drive sleeves 29 are sleeved in the middle of the two ends of the second shaft 28. In addition, a first motor 210 is provided at the end of the U-shaped plate 12. The output shaft of the first motor 210 is connected to the second shaft 28. The first motor 210 drives the second shaft 28 and the friction drive sleeves 29 to rotate. The friction drives the pressure roller ring 25 to rotate. During the rotation of the pressure roller ring 25, the scraper 27 can effectively clean the outer surface of the pressure roller ring 25. To ensure stable friction between the friction drive sleeve 29 and the pressure roller ring 25, the friction drive sleeve 29 is made of rubber. The extrusion pressure is increased by the deformation of the friction drive sleeve 29. Uniform convex strips are provided on the surface of the friction drive sleeve 29, and the surface of the pressure roller ring 25 is also relatively rough, thus having a high coefficient of friction. This ultimately achieves the purpose of increasing friction, so that the friction drive sleeve 29 can stably drive the pressure roller ring 25 to rotate after rotation.

[0030] In some embodiments, the rear of the vehicle platform 11 is provided with a water pump 15 that supplies water to the fog cannon 14, and the outlet of the water pump 15 is connected to a main pipe 16; the main pipe 16 is provided with a third branch pipe that is connected to the nozzle of the fog cannon 14 for supplying water to the fog cannon 14 and generating a large amount of atomized water.

[0031] The bottom end of the rear of the vehicle body 11 is provided with a plurality of first nozzles 26 arranged in a second direction, and the bottom surface of the mounting frame 35 near the edge of the front of the vehicle body 11 is provided with a plurality of second nozzles 316 arranged in a second direction. The first nozzle 26 and the second nozzle 316 are connected at one end to the main pipe 16, and the other ends of both spray water mist toward the front side of the vehicle panel 11.

[0032] Before the rolling compression of the pressure roller ring 25 and the vibration compression of the vibration box 37, water is sprayed through the first nozzle 26 and the second nozzle 316 to increase the soil moisture content. The moistened soil is then more easily deformed and binds together, ensuring an effective and stable compaction effect. Optionally, the first nozzle 26 and the second nozzle 316 can be adjustable fan-shaped nozzles from the MP series of Shandong Ranyuan Environmental Protection Technology Co., Ltd. One end is connected to the corresponding branch pipe via a thread, and the other end allows adjustment of the spray angle, facilitating quick installation and uniform adjustment. Furthermore, the fan-shaped nozzle significantly expands the spray range and improves the wetting effect.

[0033] In some embodiments, the main pipe 16 extends downward through the vehicle platform 11 from the end away from the water pump 15, and extends along a second direction after penetration; each first nozzle 26 is installed on the portion of the main pipe 16 located below the vehicle platform 11; a second branch pipe 318 communicating with the main pipe 16 is provided at the bottom of the vehicle platform 11, a first branch pipe 315 is provided on the bottom surface of the mounting frame 35 near the head end of the vehicle platform 11, each second nozzle 316 is installed on the first branch pipe 315, and the first branch pipe 315 and the second branch pipe 318 are flexibly connected by a connecting hose 317.

[0034] The first branch pipe 315 and the second branch pipe 318 are connected by a connecting hose 317. The bending deformation of the connecting hose 317 ensures the swing stability of the mounting frame 35. The second branch pipe 318 is connected to the bottom surface of the vehicle plate 11 via a fixing seat 319, while the first branch pipe 315 is installed at the bottom of the mounting frame 35 via the fixing seat 319. The fixing seat 319 can be a U-shaped clamp for easier installation.

[0035] In some embodiments, the mounting frame 35 has an extension rod 39 extending away from the center of the vehicle panel 11 on its end face away from the center of the vehicle panel 11. The top of the storage compartment 31 has a clearance groove 311 that fits with the extension rod 39. A dividing pin 313 is provided on the top of the storage compartment 31 corresponding to the clearance groove 311. The extension rod 39 has a pin hole 310 corresponding to the position of the dividing pin 313. A mounting base 312 is provided on the top of the storage compartment 31 corresponding to the clearance groove 311. The mounting base 312 has a mounting hole in its center, and the dividing pin 313 is inserted into the mounting hole.

[0036] By pulling the indexing pin 313, the mounting frame 35 is swung into the storage compartment 31. At this time, the extension rod 39 is inserted into the clearance groove 311. Then, the indexing pin 313 is released, and the end of the indexing pin 313 is inserted into the pin hole 310, thereby fixing the mounting frame 35. Preferably, two extension rods 39 are provided, one at each end of the mounting frame 35, and two are also provided at the corresponding parts of the extension rods 39, which improves the stability of the mounting frame 35 after it is fixed. The indexing pin 313 is a common pin locking mechanism, which will not be described in detail here.

[0037] In some embodiments, the vibration compaction box 37 is provided with a leveling component 4 near the front end of the vehicle plate 11. The leveling component 4 is used to push the soil and gravel along a second direction toward the side away from the center of the vehicle plate 11. By removing the soil and gravel, it prevents the soil and gravel from falling on the ground, causing uneven road surfaces, which is not conducive to vibration compaction.

[0038] In some embodiments, the leveling component 4 includes: The trapezoidal shovel plate 44 has a right-angled trapezoidal cross section. Its right-angled side is connected to the shock-absorbing box 37, and the top is provided with an installation groove 45. The installation groove 45 is provided with a ramp block 46 inside. The ramp block 46 has a first acute angle between its inclined surface and the bottom surface of the trapezoidal shovel plate 44. The opening of the first acute angle faces the center side of the vehicle plate 11. A frustum sleeve 43 is rotatably mounted on the central side surface of the vibration pressure box 37 away from the vehicle plate 11. The outer diameter of the end of the frustum sleeve 43 near the vibration pressure box 37 is larger than the outer diameter of the other end. Inside the frustum sleeve 43, a third shaft 41 is mounted via a mounting rod 42. The third shaft 41 is rotatably connected to the side end face of the vibration pressure box 37 to ensure the installation stability of the frustum sleeve 43.

[0039] During the vibration compaction process, the raised parts of the road are removed by the trapezoidal shovel plate 44. The shoveled soil will enter the installation groove 45 along the inclined side of the trapezoidal shovel plate 44. Finally, with the vibration of the vibration compaction box 37, the soil will be shaken and sent out along the side of the inclined block 46 because the inclined block 46 has a first acute angle with the opening facing the center side of the vehicle plate 11. Then, the round sleeve 43 squeezes these sent soil blocks, which achieves a simple compaction effect. This not only ensures the flatness of the road, but also prevents the soil blocks at the edge of the road from raising dust after compaction. Optionally, a baffle 47 is provided near the center end of the trapezoidal shovel plate 44 near the center of the vehicle plate 11. During the vibration process, the soil blocks will not fall under the vehicle plate 11, ensuring that the soil blocks can be effectively and stably shaken off to the outside of the vehicle plate 11.

[0040] In some embodiments, the second leveling mechanism 3 further includes a solar panel 5, which includes a plurality of photovoltaic panels 52 for generating electricity and mounted on the top surface of the mounting frame 35, and a cleaning structure for cleaning the surface of the photovoltaic panels 52, the cleaning structure being used to wipe the light-receiving surface of the photovoltaic panels 52.

[0041] The photovoltaic panel 52 is placed on the mounting frame 35 to generate electricity through sunlight, achieving energy-saving effects. Furthermore, the photovoltaic panel 52 can be retracted into the storage compartment 31 along with the mounting frame 35, preventing dust accumulation on its surface due to long-term exposure, thus avoiding a reduction in photovoltaic efficiency. A cleaning structure is also included to further reduce dust on the surface of the photovoltaic panel 52, ensuring long-term effective solar power generation. The vehicle platform 11 is also equipped with a photovoltaic controller and inverter. The photovoltaic panel 52 is connected to the vehicle's power supply through the photovoltaic controller and inverter, achieving the purpose of power conversion, transmission, and storage. The power generation system of the photovoltaic panel 52, photovoltaic controller, and inverter is a common solar power generation combination, which will not be described in detail here.

[0042] In some embodiments, the cleaning structure includes a second acute angle between the photovoltaic panel 52 and the mounting frame 35, with the opening of the second acute angle facing away from the center of the vehicle panel 11; optionally, a pad 51 is provided on the side of the photovoltaic panel 52 away from the center of the vehicle panel 11, and the angle of the photovoltaic panel 52 is increased by the pad 51 to form the second acute angle.

[0043] A semi-circular wiping pad 55 is abutted against the top surface of the photovoltaic panel 52. The top of the semi-circular wiping pad 55 is detachably installed at the bottom of the connecting rod 54. The top of the connecting rod 54 is provided with several sliding rods 53 extending toward the center of the vehicle plate 11. The ends of the sliding rods 53 away from the connecting rod 54 slide through the bottom of the storage compartment 31 and are equipped with end plates 56. A spring 57 is provided between the end plate 56 and the outer wall of the storage compartment 31.

[0044] During the installation of the frame 35 and the storage of the photovoltaic panel 52, the semi-circular wiping pad 55 and the sliding rod 53 move towards the center of the vehicle platform 11, causing the spring 57 to extend and generate elastic stress, thus wiping the photovoltaic panel 52 before storage. During the release of the frame 35 and the photovoltaic panel 52, the semi-circular wiping pad 55 and the sliding rod 53 are reset by the elastic stress of the spring 57, thus storing the photovoltaic panel 52 before unfolding, achieving a thorough and effective cleaning effect and ensuring the power generation efficiency of the photovoltaic panel 52. The water tank 17 is installed in the middle of the vehicle platform 11. Preferably, a second support frame 58 is provided in the middle of the vehicle platform 11, and the water tank 17 is installed at the top of the second support frame 58, leaving space for the sliding rod 53 to slide, avoiding interference between the sliding rod 53 and the water tank 17.

[0045] refer to Figure 11 and Figure 14 As shown, Figure 14 The dashed line in the diagram represents the photovoltaic panel 52, and the origin O indicates the force analysis of the semicircular wiping pad 55. During the installation of the frame 35 and the storage of the photovoltaic panel 52, the photovoltaic panel 52 applies an upward stress F to the semicircular wiping pad 55. The direction of the sliding rod 53 is the X-axis direction. The stress F is decomposed into a vertical stress Fy and a horizontal stress Fx. The stress Fx can push the sliding rod 53 to move towards the center of the vehicle panel 11. As the photovoltaic panel 52 swings, the second acute angle A gradually increases, and the stress Fx will also gradually increase, ensuring the stable movement of the sliding rod 53.

[0046] In some embodiments, the sliding rod 53 should have good strength (fracture resistance) and stiffness (rigid deformation). Therefore, high-strength alloy steel (such as 42CrMoA, 36Mn2V) can be selected to ensure that the sliding rod 53 will not break or deform under stress. To avoid excessive friction between the sliding rod 53 and the storage compartment 31, which would make it difficult for the sliding rod 53 to move horizontally, since the frictional force f=uFy, where u is the coefficient of friction and the vertical stress Fy is the compressive force, more preferably, under the condition that the compressive force Fy remains unchanged, the surface roughness Ra of the contact surface between the sliding rod 53 and the storage compartment 31 is 0.8 μm, which serves to reduce the coefficient of friction u. When the surface roughness Ra is less than 0.8 μm, the surface can be called "mirror surface", which is highly smooth. However, the smaller the surface roughness Ra, the more difficult the processing becomes, which is not conducive to large-scale production. Optionally, to avoid mutual interference between the sliding rods 53 on both sides of the vehicle plate 11, reference can be made to Figure 13 As shown, the sliding rods 53 on both sides are staggered to avoid mutual interference.

[0047] In some embodiments, a rubber damping sleeve 24 is installed inside the first shaft 22, and the top of the vibration-damping box 37 is connected to the bottom of the mounting frame 35 via a damping damper 36. During the rolling and pressing of the pressure roller ring 25 against the ground, the local deformation of the rubber damping sleeve 24 absorbs any potential jumping of the pressure roller ring 25, ensuring the stability of its movement. The damping damper 36 reduces the reaction force of the vibration-damping box 37 on the mounting frame 35, preventing damage to the mounting frame 35 caused by the vibration of the vibration-damping box 37, and also reducing the impact of the vibration of the vibration-damping box 37 on the vehicle body 11. The damping damper 36 is a common vibration damping structure. Optionally, the damping damper 36 is a vibration isolator of model AGS-55B from Qingdao Aiborui Vibration Isolation Technology Co., Ltd. By setting a mounting connecting plate at the bottom of the mounting frame 35, several vibration isolators are evenly distributed on the mounting connecting plate, achieving a uniform and effective vibration damping effect.
