Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to a vehicle-mounted environmentally friendly dust removal device. Background Art

[0002] Vehicles passing by on the road and road construction generate dust, which pedestrians and drivers in the car will inhale, causing harm to the body. The floating dust will also reduce the visibility of the air. Dust pollution is one of the important links in air pollution control. At present, in order to deal with the dust generated during highway construction, atomizing spray devices are often used to achieve dust reduction and dust removal. At present, there are special dust removal vehicles that are equipped with atomizing spray devices to remove dust while driving.

[0003] The utility model patent with the announcement number CN214552126U discloses an environmentally friendly dust removal device for highway engineering construction, including a vehicle body, a water tank is provided on the vehicle body, a high-pressure water pump is fixedly installed on one side of the top surface of the water tank, the lower part of one side of the water tank is fixedly connected to one end of the water inlet pipe, the water inlet of the high-pressure water pump is fixedly connected to the other end of the water inlet pipe, a vertical pipe is fixedly installed at the center of the top surface of the water tank, the upper end of the vertical pipe is rotatably installed with a connecting pipe through a sealed bearing, a fog cannon barrel is fixedly installed on the upper section of the connecting pipe, an angle adjustment device is provided on the outer periphery of the connecting pipe, and a dust removal device is fixedly installed in the fog cannon barrel. The device can increase the swing angle of the fog cannon barrel through the angle adjustment device, increase the spraying range of the first atomizing spray head, and remove dust from the air through the dust removal device in the fog cannon barrel.

[0004] Although the dust removal device can adjust the angle horizontally to expand the spray range, the vertical elevation angle cannot be automatically raised or lowered during the spraying process. The existing invention patent application with publication number CN112359771A discloses a safe and energy-saving sprayer for a municipal sprinkler truck. A lifting push rod is provided on the upper fixed plate on the right side of the body, and a spray fan is provided on the upper end of the rear support rod and the lifting push rod. There are two lifting push rods in total, and the lifting push rods are symmetrically fixed on the outer front end of the spray fan; the lifting push rod includes a connecting T-block, an intermediate shaft rod and a push rod cylinder body, and an intermediate shaft rod is provided inside the push rod cylinder body. A connecting T-block is provided on the upper end of the intermediate shaft rod, and the connecting T-block is connected to the spray fan, and the push rod cylinder body is connected to the upper fixed plate; specifically, through the lifting push rods on both sides of the front end of the spray fan, it is convenient to adjust the upper and lower angles of the spray. The lifting push rod generally adopts an oil cylinder.

[0005] Combining the above two solutions can produce a spray device that can swing horizontally and up and down to maximize the spray range. However, the use of a cylinder to adjust the up and down angles of the spray barrel requires a hydraulic system. On the one hand, this increases cost and weight. On the other hand, the cylinder and its hydraulic system are easily damaged in the event of vehicle vibration, requiring frequent maintenance. Once an oil leak occurs, it will have a serious impact on the road surface, which needs to be improved. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a vehicle-mounted environmentally friendly dust removal device, which can swing up and down while the spray blower swings horizontally, and the up and down swinging does not rely on a cylinder or other driving source, thereby reducing costs and avoiding problems such as oil cylinder leakage and the need for maintenance.

[0007] The above technical purpose of the utility model is achieved through the following technical scheme: a vehicle-mounted environmentally friendly dust removal device, comprising a base plate and a swivel seat rotatably connected to the base plate, a motor for driving the swivel seat to rotate is fixed to the base plate, a spray cylinder is rotatably connected to the swivel seat, a base frame is fixed to the base plate, an arc-shaped track plate is fixed to the base frame, the bottom of the spray cylinder is fixedly connected to a support rod, the bottom of the support rod is rotatably connected to a roller, the roller is in rolling contact with the top surface of the track plate, and there is a height difference between the track plate and the top surface of the track plate in the vertical direction.

[0008] Through the above technical solution, the motor drives the rotating seat to rotate, so that the spray air cylinder swings left and right. While the spray air cylinder swings left and right, the roller at the bottom of the support rod rolls on the track plate. Due to the height difference of the track plate in the vertical direction, the spray air cylinder is driven to rotate around the hinge position with the rotating seat, thereby automatically realizing the up and down swing of the spray air cylinder. The up and down swing of the spray air cylinder does not rely on other driving sources.

[0009] Preferably, the track plate is high at both ends and low in the middle.

[0010] Through the above technical solution, when the motor is accidentally powered off, the roller can spontaneously roll to the lowest point in the middle of the track plate under the action of the pressure from above, avoiding accidents. When the roller is at the lowest point, the height of the spray blower is also the lowest and can be stored on the vehicle.

[0011] Preferably, a reinforcement plate is fixed between the bottom surface of the track plate and the base frame.

[0012] Through the above technical solution, the reinforcing plate is used to strengthen the fixing strength between the track plate and the base frame to prevent the track plate from bending downward under pressure.

[0013] Preferably, an extension rod is fixed to the bottom end of the support rod, and a secondary wheel is rotatably connected to the extension rod via an elastic structure, and the secondary wheel is in rolling contact with the bottom surface of the track plate.

[0014] Through the above technical solution, the track plate can be clamped between the auxiliary wheel and the roller through the cooperation between the two, thereby preventing the roller from excessively detaching from the track plate upward, which is safer.

[0015] Preferably, the elastic structure includes a telescopic rod and a spring sleeved outside the telescopic rod, one end of the telescopic rod is fixed to the extension rod, the other end of the telescopic rod is fixed to a rotating frame, and the secondary wheel is rotatably connected to the rotating frame.

[0016] Through the above technical solution, when the roller moves on the track plate, the spring and the telescopic rod adaptively expand and contract, so that the auxiliary wheel can be closely attached to the bottom surface of the track plate, providing continuous guiding and limiting effects.

[0017] Preferably, limit plates are fixed at both ends of the track plate.

[0018] Through the above technical solution, the limit plate plays the function of limiting the extreme position of the roller, thereby preventing the roller from detaching from the end of the track plate.

[0019] Preferably, the side wall of the spray air cylinder is provided with an outwardly connected air outlet pipe, the air outlet pipe is provided with a solenoid valve, and the other end of the air outlet pipe faces the contact position between the roller and the track plate.

[0020] Through the above technical solution, after the solenoid valve is opened, a small amount of airflow in the spray blower can be blown out from the outlet pipe, thereby blowing and cleaning the contact position between the roller and the track plate, preventing dust and garbage falling on the track plate from affecting the rolling of the roller.

[0021] Preferably, the air outlet pipe is a hose, and a block engaged with the outer wall of the air outlet pipe is fixed on the extension rod.

[0022] Through the above technical solution, personnel can remove the air outlet pipe from the block, hold the air outlet pipe and perform targeted blowing cleaning on the position that needs to be cleaned, which is more convenient.

[0023] In summary, the beneficial effects of the present invention compared with the prior art are as follows:

[0024] 1. The spray blower can swing up and down while swinging horizontally, and the up and down swinging does not rely on the oil cylinder or other driving source, which reduces the cost and weight;

[0025] 2. There will be no problem of oil cylinder leakage or need for maintenance.

[0026] 3. By setting up the air outlet pipe, it is convenient to clean the track plate and other locations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0032] Reference Figure 1 , is a vehicle-mounted environmentally friendly dust removal device disclosed by the utility model, comprising a base plate 1, a rotating seat 11 rotatably connected to the base plate 1, a motor 12 for driving the rotating seat 11 to rotate is fixed on the base plate 1, and a spray air cylinder 2 is rotatably connected to the rotating seat 11. The base plate 1 is used to be fixed to the spray vehicle, the motor 12 can rotate forward and reverse, and the output end of the motor 12 and the rotating seat 11 are respectively fixed with gears, and the two gears are meshed to achieve transmission. The spray air cylinder 2 is a prior art, which extracts water from the water tank, atomizes it through the atomizing nozzle, and sprays the water mist at high speed in combination with the internal fan, thereby achieving dust removal.

[0033] Reference Figure 1 and Figure 2 The bottom plate 1 is fixed with a bottom frame 3, and an arc-shaped track plate 31 is fixed with the bottom frame 3. The bottom of the spray air cylinder 2 is fixedly connected with a support rod 21, and the bottom of the support rod 21 is rotatably connected with a roller 22, and the roller 22 is in rolling contact with the top surface of the track plate 31. The track plate 31 has a height difference in the vertical direction, and specifically, the track plate 31 is high at both ends and low in the middle.

[0034] By setting the arc-shaped track plate 31, when the rotating seat 11 rotates, the support rod 21 is always in contact with the top surface of the track plate 31. Through the uneven shape of the track plate 31, the support rod 21 can be driven by the roller 22 to move up and down, thereby driving the spray barrel 2 to rotate around its hinge axis, and realizing the angle change of the spray barrel 2 in the vertical direction. By setting the track plate 31 to be high at both ends and low in the middle, when the motor 12 is accidentally powered off, the roller 22 can roll to the lowest point in the middle of the track plate 31 under the action of the upper pressure to avoid accidents, and when the roller 22 is at the lowest point, the height of the spray barrel 2 is also the lowest, and it can be stored in the vehicle, and in this state, the spray barrel 2 does not protrude from the left and right sides of the vehicle, avoiding the spray barrel 2 from hitting the wall when the spray vehicle passes through the tunnel.

[0035] Reference Figure 1 and Figure 3 Limiting plates 32 are fixed at both ends of the track plate 31. The limiting plates 32 protrude upward from the track plate 31 in the vertical direction. When the roller 22 contacts the limiting plates 32, it cannot move further. The limiting plates 32 limit the extreme position of the roller 22 to prevent the roller 22 from detaching from the end of the track plate 31.

[0036] A reinforcing plate 33 is fixed between the bottom surface of the track plate 31 and the base frame 3. The reinforcing plate 33 is triangular and there are multiple reinforcing plates 33. The reinforcing plates 33 are used to strengthen the fixing strength between the track plate 31 and the base frame 3 to prevent the track plate 31 from bending downward under pressure.

[0037] Reference Figure 1 and Figure 2 The bottom end of the support rod 21 is fixed with an extension rod 4, and the extension rod 4 is rotatably connected with a secondary wheel 41 through an elastic structure, and the secondary wheel 41 is in rolling contact with the bottom surface of the track plate 31. The elastic structure includes a telescopic rod 42 and a spring 43 sleeved outside the telescopic rod 42, one end of the telescopic rod 42 is fixed to the extension rod 4, and the other end of the telescopic rod 42 is fixed with a rotating frame 44, the secondary wheel 41 is rotatably connected with the rotating frame 44, and the two ends of the spring 43 are respectively in contact with the extension rod 4 and the rotating frame 44.

[0038] The auxiliary wheel 41 cooperates with the roller 22 to sandwich the track plate 31 therebetween, thereby preventing the roller 22 from excessively disengaging from the track plate 31 upwards, which is safer. When the roller 22 moves on the track plate 31, the spring 43 and the telescopic rod 42 adaptively expand and contract, so that the auxiliary wheel 41 can be closely attached to the bottom surface of the track plate 31, providing a continuous guiding and limiting effect.

[0039] The side wall of the spray air cylinder 2 is provided with an air outlet pipe 5 connected to the outside. The air outlet pipe 5 is a hose. The air outlet pipe 5 is close to the air outlet position of the spray air cylinder 2. The air outlet pipe 5 is provided with a solenoid valve 51. The other end of the air outlet pipe 5 faces the contact position between the roller 22 and the track plate 31. A block 52 is fixed on the extension rod 4 to engage with the outer wall of the air outlet pipe 5. The block 52 is connected to the air outlet pipe 5 through a slot provided on the side wall. After opening the solenoid valve 51, a small amount of airflow in the spray air cylinder 2 can be blown out from the air outlet pipe 5, so as to blow and clean the contact position between the roller 22 and the track plate 31, and avoid dust and garbage falling on the track plate 31 from affecting the rolling of the roller 22. The opening and closing of the solenoid valve 51 is controlled by personnel. After parking, personnel can remove the air outlet pipe 5 from the block 52, and hold the air outlet pipe 5 to blow and clean the position to be cleaned, which is more convenient.

[0040] The working principle of a vehicle-mounted environmentally friendly dust removal device of the present embodiment is as follows: the motor 12 drives the rotating seat 11 to rotate, so that the spray barrel 2 swings left and right. While the spray barrel 2 swings left and right, the roller 22 at the bottom of the support rod 21 rolls on the track plate 31. Since the track plate 31 is undulating, it will drive the spray barrel 2 to rotate around the hinge position with the rotating seat 11, thereby automatically realizing the up and down swing of the spray barrel 2.

[0041] In summary, the spray blower 2 in the present application swings up and down while swinging horizontally, and the up and down swinging does not rely on the oil cylinder or other driving sources, which reduces the cost and weight, and there will be no problems of oil cylinder leakage and the need for maintenance.

[0042] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
