Technical Field

[0001] The utility model relates to the technical field of environmental protection equipment, in particular to a dust cleaner. Background Art

[0002] As is well known, dust is easily generated during the operation of construction sites and waste recycling plants, and dust is also easily generated during the driving of muck trucks, which causes a certain degree of air pollution, increases the concentration of PM2.5 and PM10, and affects human respiratory health. Therefore, it is necessary to carry out dust prevention treatment on places and equipment prone to generate dust.

[0003] Chinese Utility Model Patent CN221131580U discloses a dust cleaning device, which includes a housing and a filter. A suction fan is fixed at the bottom end of the outer wall on one side of the housing, and an air suction pipe is fixed at the top of the suction fan. An air delivery pipe is fixed at the bottom of the suction fan. A main pipe is arranged on the inner side wall of the housing, a branch pipe is arranged at the top of the main pipe, and air holes are formed in the outer wall of the branch pipe. The filter is fixed at the top end on the side of the housing away from the suction fan.

[0004] This dust cleaning device can only suck air through the suction fan. In actual construction, most of the dust accumulates on the ground, and this device cannot clean the dust on the ground, resulting in poor cleaning effect. At the same time, due to the complex environment at the civil engineering construction site and the uneven ground, if the installation height of the air suction pipe is relatively low, although it can suck the dust on the ground to a certain extent, it is easily damaged by the impact of raised obstacles on the ground during the progress. Therefore, it is necessary to provide a dust cleaner that can solve the problems that the existing dust cleaning device cannot effectively clean the dust on the ground and is easily damaged by obstacles. Summary of the Invention

[0005] The purpose of the utility model is to provide a dust cleaner that can solve the problems that the existing dust cleaning device cannot effectively clean the dust on the ground and is easily damaged by obstacles.

[0006] The utility model is realized as follows:

[0007] A dust cleaner, comprising a vehicle body, a cleaning water tank, a suction pipe, a collection hood, a lifting assembly, a first support plate, a rotating connection block, a motor, a cleaning brush, a water supply tank and a drain pipe; the cleaning water tank and the water supply tank are fixedly arranged on the top of the vehicle body, and the top of the cleaning water tank is communicated with the water supply tank through the drain pipe; the collection hood is arranged on the side of the vehicle body in a liftable manner through the lifting assembly, so that the collection cavity of the collection hood faces the ground, one end of the suction pipe is communicated below the water surface in the cleaning water tank, and the other end of the suction pipe is communicated with the collection cavity of the collection hood; the first support plate is installed at the bottom of the vehicle body, the rotating connection block is rotatably installed on the first support plate, the motor is installed at the bottom of the rotating connection block, the output shaft of the motor faces the ground and is coaxially fixedly connected with the cleaning brush, so that the bristles of the cleaning brush are in rotational contact with the ground.

[0008] A rotating shaft is rotatably penetrated through the rotating connection block, and both ends of the rotating shaft are respectively fixedly installed on a pair of first support plates, so that the rotating connection block is rotatably arranged below the vehicle body and between the pair of first support plates.

[0009] A pair of second support plates are installed at the bottom of the vehicle body, the pair of first support plates and the pair of second support plates are symmetrically arranged around the rotating connection block respectively, and the pair of second support plates and the rotating connection block are correspondingly connected through a pair of shock-absorbing springs.

[0010] The axial direction of the shock-absorbing spring is parallel to the traveling direction of the vehicle body and perpendicular to the axial direction of the rotating shaft of the rotating connection block.

[0011] The suction pipe comprises a first connecting pipe and a second connecting pipe. One end of the first connecting pipe is inserted into the cleaning water tank from the upper part of the cleaning water tank and extends below the water surface. The other end of the first connecting pipe is telescopically inserted into one end of the second connecting pipe. A dynamic sealing ring is arranged between the first connecting pipe and the second connecting pipe. The other end of the second connecting pipe is communicated with the collection cavity of the collection hood; the lifting assembly is connected with the second connecting pipe.

[0012] The lifting assembly comprises a first fixing plate, an electric telescopic rod and a second fixing plate; the fixed end of the electric telescopic rod is fixedly installed on the outer wall of the cleaning water tank through the second fixing plate, the telescopic end of the electric telescopic rod is connected with the second connecting pipe through the first fixing plate, and the electric telescopic rod is arranged beside the suction pipe.

[0013] One end of the top of the vehicle body is connected with a handrail, and the handrail is located beside the water supply tank.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. Since the utility model is provided with a motor, a cleaning brush and a collection hood, when the motor drives the cleaning brush to rotate, the cleaning brush sweeps the dust on the ground to both sides, which facilitates the collection hood to suck the dust by negative pressure and send it into the cleaning water tank through the dust suction pipe for dust removal. At the same time, the collection hood can adjust the height from the ground through the lifting component, so as to achieve a better dust treatment effect.

[0016] 2. Since the utility model is provided with a rotating connection block, a shock-absorbing spring and a rotating shaft, when the cleaning brush moves forward with the vehicle body and collides with a raised obstacle on the ground, the impact force is transmitted to the rotating connection block, causing it to rotate around the rotating shaft and cross the obstacle. At the same time, the two shock-absorbing springs are respectively compressed and stretched, and the deformation elastic force of the shock-absorbing spring is used to buffer the impact force and pull the rotating connection block back to its original position.

[0022] The following further describes the utility model with reference to the accompanying drawings and specific embodiments.

[0023] Please refer to the attached Figure 1 to the attached Figure 3, A dust cleaner, comprising a vehicle body 1, a cleaning water tank 2, a suction pipe, a collection hood 5, a lifting assembly, a first support plate 9, a rotating connection block 10, a motor 11, a cleaning brush 12, a water supply tank 15 and a drain pipe 16; The cleaning water tank 2 and the water supply tank 15 are fixedly arranged on the top of the vehicle body 1, and the top of the cleaning water tank 2 is communicated with the water supply tank 15 through the drain pipe 16; The collection hood 5 is arranged on the side of the vehicle body 1 in a liftable manner through the lifting assembly, so that the collection cavity of the collection hood 5 faces the ground, and one end of the suction pipe is communicated below the water surface in the cleaning water tank 2, and the other end of the suction pipe is communicated with the collection cavity of the collection hood 5; The first support plate 9 is installed at the bottom of the vehicle body 1, the rotating connection block 10 is rotatably installed on the first support plate 9, the motor 11 is installed at the bottom of the rotating connection block 10, and the output shaft of the motor 11 faces the ground and is coaxially fixedly connected with the cleaning brush 12, so that the bristles of the cleaning brush 12 are in rotational contact with the ground.

[0024] Preferably, the collection hood 5 can adopt a high-pressure dust suction hood body in the prior art, using a high-pressure air pump to generate negative pressure, so as to drive the dust on the ground into the collection hood 5 through the high-speed flowing air flow, and then enter the cleaning water tank 2 through the suction pipe. Since the suction pipe extends below the water surface of the cleaning water tank 2, the air can enter the water to intercept the dust mixed in the air, achieving the purpose of dust removal.

[0025] The first support plate 9, the rotating connection block 10, the motor 11 and the cleaning brush 12 are set in groups, and the arrangement group number and spacing can be adaptively adjusted according to the size of the vehicle body 1 and the actual use requirements, and the motor specifications can be adaptively selected according to the cleaning requirements. The motor 11 drives the cleaning brush 12 to rotate, which can raise the dust on the ground, facilitating the collection hood 5 to more efficiently and conveniently suck the dust on the ground. Preferably, the collection hood 5 can be arranged on both sides of the vehicle body. When the cleaning brush 12 rotates, the dust on the ground is thrown out by centrifugal force and is sucked by the collection hoods 5 on both sides.

[0026] The cleaning brush 12 moves synchronously with the movement of the vehicle body 1. If it encounters a convex obstacle on the ground, the impact force causes the rotating connection block 10, the motor 11 and the cleaning brush 12 to rotate synchronously. During the rotation process, the height of the cleaning brush 12 is raised, so that it can cross the convex obstacle and avoid collision damage.

[0027] Preferably, a water pump can be installed on the drain pipe 16 to pump the water in the water supply tank 15 into the cleaning water tank 2 through the drain pipe 16 to provide water supply for the cleaning water tank 2, and the empty water supply tank 15 can also be used for temporarily storing the sewage in the cleaning water tank 2.

[0028] Please refer to the appendix Figure 3 , A rotating shaft 17 is rotatably penetrated through the rotating connection block 10, and both ends of the rotating shaft 17 are fixedly installed on a pair of first support plates 9, so that the rotating connection block 10 is rotatably arranged below the vehicle body 1 and between a pair of first support plates 9.

[0029] Both ends of the rotating shaft 17 are installed on a pair of first support plates 9. The rotating connection block 10 rotates relative to the rotating shaft 17, which can improve the rotational stability and flexibility of the rotating connection block 10, so as to rotate in time under the impact force of the raised obstacle, thereby realizing the function of crossing the raised obstacle.

[0030] Please refer to the attached Figure 2 and the attached Figure 3 , a pair of second support plates 13 are installed at the bottom of the vehicle body 1. A pair of first support plates 9 and a pair of second support plates 13 are symmetrically arranged around the rotating connection block 10 respectively, and a pair of shock-absorbing springs 14 are correspondingly connected between the pair of second support plates 13 and the rotating connection block 10.

[0031] The second support plate 13 is used to install the shock-absorbing spring 14. The shock-absorbing springs 14 are arranged in pairs on both sides of the rotating direction of the rotating connection block 10. The shock-absorbing springs 14 can be made of a metal material with a small elastic coefficient, so as to quickly deform when receiving an impact force, without hindering the rotation of the rotating connection block 10, and can provide sufficient elastic force required for resetting.

[0032] When the rotating connection block 10 rotates, one shock-absorbing spring 14 is stretched and the other shock-absorbing spring 14 is compressed. The deformation of the shock-absorbing spring 14 generates elastic force, which is used to pull the rotating connection block 10 to rotate and reset. The elastic force of the shock-absorbing spring 14 also provides a shock-absorbing effect for buffering the impact force on the rotating connection block 10, the motor 11 and the cleaning brush 12 at the same time.

[0033] Please refer to the attached Figure 2 and the attached Figure 3 , the axial direction of the shock-absorbing spring 14 is parallel to the traveling direction of the vehicle body 1 and perpendicular to the axial direction of the rotating shaft 17 of the rotating connection block 10.

[0034] During the traveling of the vehicle body 1, the raised obstacle usually acts on the cleaning brush 12 with a force opposite to the traveling direction. Install the axial directions of the two shock-absorbing springs 14 along the front-back direction of the vehicle body, that is, the traveling direction, so that the two shock-absorbing springs 14 can be stretched and compressed respectively during the collision, and then the elastic force acts on the rotating connection block 10.

[0035] When the two shock-absorbing springs 14 are in the natural state, the cleaning brush 12 can be set perpendicular to the ground, so as to facilitate the cleaning of dust.

[0036] The described dust suction pipe includes a first connecting pipe 3 and a second connecting pipe 4. One end of the first connecting pipe 3 is inserted into the cleaning water tank 2 from the upper part and extends below the water surface. The other end of the first connecting pipe 3 is telescopically inserted into one end of the second connecting pipe 4. A dynamic sealing ring is provided between the first connecting pipe 3 and the second connecting pipe 4. The other end of the second connecting pipe 4 communicates with the collection chamber of the collection hood 5; the lifting assembly is connected to the second connecting pipe 4.

[0037] The first connecting pipe 3 is used to extend into the cleaning water tank 2 and send the high-speed air flow mixed with dust into the water in the cleaning water tank 2, so as to filter out the dust. The second connecting pipe 4 is used to connect the first connecting pipe 3 and the collection hood 5, so as to send the high-speed air flow mixed with dust in the collection hood 5 into the first connecting pipe 3; due to the setting of the dynamic sealing ring, it is ensured that the air flow will not overflow from the gap between the first connecting pipe 3 and the second connecting pipe 4 during the transportation process, and it can also ensure that the second connecting pipe 4 moves up and down relative to the first connecting pipe 3 under the action of the lifting assembly, so as to achieve the purpose of adjusting the height of the collection hood 5.

[0038] Please refer to the attached Figure 1 As shown, the described lifting assembly includes a first fixing plate 6, an electric telescopic rod 7 and a second fixing plate 8; the fixed end of the electric telescopic rod 7 is fixedly installed on the outer wall of the cleaning water tank 2 through the second fixing plate 8, and the telescopic end of the electric telescopic rod 7 is connected to the second connecting pipe 4 through the first fixing plate 6. The electric telescopic rod 7 is arranged beside the dust suction pipe.

[0039] Preferably, the electric telescopic rod 7 can adopt a pneumatic or hydraulic telescopic rod. After the electric telescopic rod 7 is connected to the power supply, air pressure or hydraulic pressure is injected or extracted to drive the piston rod, that is, the telescopic end of the electric telescopic rod 7, to perform telescopic movement, so as to drive the second connecting pipe 4 to perform synchronous lifting movement through the first fixing plate 6.

[0040] The first fixing plate 6 is used to connect the second lifting pipe 4 and the piston rod of the electric telescopic rod 7. When installing the first fixing plate 6, attention should be paid to avoiding collision with the vehicle body 1 during its movement trajectory. The second fixing plate 8 is used to fixedly install the main body part, that is, the fixed end, of the electric telescopic rod 7, so that the electric telescopic rod 7 is vertically arranged beside the dust suction pipe.

[0041] Please refer to the attached Figure 1 As shown, one end of the top of the vehicle body 1 is connected with a handrail 18, and the handrail 18 is located beside the water supply tank 15.

[0042] The handrail 18 is convenient for on-site personnel to hold and push the vehicle body 1 to move. Preferably, the vehicle body 1 and the handrail 18 can adopt a flatbed truck in the prior art, with a simple structure and easy to obtain materials and use.

[0043] Please refer to the attached Figure 1 to the attached Figure 4 As shown, the usage method and working principle of the present utility model are as follows:

[0044] Start the electric telescopic rod 7. The telescopic end of the electric telescopic rod 7 extends downward or retracts upward, and drives the second connecting pipe 4 to move upward or downward synchronously through the first fixing plate 6. The second connecting pipe 4 drives the collection hood 5 to lift and lower synchronously, so as to adjust the height of the collection hood 5 from the ground, taking into account the effects of sucking dust and preventing collision.

[0045] On-site staff hold the handrail 18 and push the vehicle body 1 to move flexibly on-site. While the vehicle body 1 is moving, the collection hood 5 sucks the dust on the ground. The dust enters the cleaning water tank 2 through the second connecting pipe 4 and the first connecting pipe 3 along with the high-speed flowing air, so that the dust settles after entering the water, achieving the purpose of dust removal.

[0046] The air is discharged from the exhaust port preset at the top of the cleaning water tank 2 to ensure the pressure balance in the cleaning water tank 2. If the water volume in the cleaning water tank 2 is insufficient or turbid, the water in the water supply tank 15 can be used to replenish and replace the water in the cleaning water tank 2.

[0047] While the vehicle body 1 is moving, the motor 11 drives the cleaning brush 12 to rotate. The cleaning brush 12 rotates to clean the dust on the ground, which is beneficial for the collection hood 5 to suck the dust on the ground with the highest efficiency and improve the effect of ground dust treatment. If there are raised obstacles on the ground during the movement of the vehicle body 1, the collision force can drive the rotating connection block 10, the motor 11 and the cleaning brush 12 to rotate around the rotating shaft 17 in the direction opposite to the advancing direction of the vehicle body 1, so that the raised obstacles can be avoided by rotation without hindering the advancement of the vehicle body 1 and preventing collision damage.

[0048] During the rotation of the rotating connection block 10, the shock-absorbing spring 14 located on the front side of the advancing direction of the vehicle body 1 is stretched, and the shock-absorbing spring 14 located on the rear side of the advancing direction of the vehicle body is compressed. By using the elastic force generated by the deformation of the two shock-absorbing springs 14, the rotating connection block 10 can be quickly reset after passing over the raised obstacle, facilitating the cleaning brush 12 to continue cleaning the dust accumulated on the ground.

[0049] Most of the collision forces generated during the movement of the vehicle body 1 are in the advancing direction. Inevitably, the collision received by the cleaning brush 12 may also have a lateral deviation. The shock-absorbing spring 14 can generate a torsional deformation. The diameter of the rotating shaft 17 is slightly smaller than the through hole in the rotating connection block 10, ensuring the rotation and reset function of the rotating connection block 10 during impact, so as to facilitate the quick reset of the cleaning brush 12.

[0050] The above is only the preferred embodiment of the present invention and is not used to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
