[0002] With the continuous acceleration of my country's urbanization process, the demand for urban road cleaning and environmental sanitation maintenance is increasing. As an efficient sanitation equipment, sweepers have been widely used in municipal cleaning, park cleaning and other fields. It can not only greatly improve cleaning efficiency and reduce manual labor intensity, but also effectively improve environmental sanitation quality, which is of great significance to improving the overall image of the city.

[0003] However, existing sweepers still have many technical pain points in actual use. The main brushes of some sweepers do not fit the ground well, which greatly reduces the cleaning effect on uneven roads. The side brushes are not flexible in adjusting the angle, making it difficult to completely remove residual garbage in the corners. At the same time, dust is easily generated during the cleaning process, affecting the air quality. In addition, the sweepers lack efficient high-pressure flushing functions and cannot deeply clean road stains, making it difficult to meet cleaning needs in complex environments.

[0050] See also Figure 1 、 Figure 2 and Figure 7 The present invention provides an embodiment of a sweeper with a high-pressure washing function, comprising a vehicle body 1, a cleaning system, the cleaning system comprising an adaptive adjustment component and a spring push rod, the adaptive adjustment component comprising a U-shaped frame 2, a swing arm 3 and a buffer spring 4, the U-shaped frame 2 is fixedly installed at the bottom of the vehicle body 1, and the U The inner side of the frame 2 is hinged to one end of the swing arm 3 through a pin 5, and the other end of the swing arm 3 is rotatably connected to the main brush 7 through a first bearing 6. A first motor 8 is installed above the bearing 6, and a buffer link 9 is installed between the swing arms 3. A slide groove 10 is opened in the middle of the buffer link 9, and a slide rail 11 is installed on the inner wall of the slide groove 10. A limit block 12 is installed on the inner wall of the slide rail 11. A buffer spring 4 is installed between the inner wall of the limit block 12 and the inner wall of the slide rail 11. The spring push rod includes a sleeve 13, a pressure spring 14 and a piston rod 15. One end of the sleeve 13 is fixedly connected to the upper surface of the outer wall of the swing arm 3, and a pressure spring 14 is set inside the sleeve 13. One end of the pressure spring 14 abuts against the bottom of the sleeve 13, and the other end is connected to one end of the piston rod 15. The other end of the piston rod 15 extends out of the sleeve 13 and is fixedly connected to the bottom of the vehicle body 1. This structure allows the main brush to flexibly adapt to the ups and downs of the ground to ensure the cleaning effect. The spring push rod provides stable pressure to improve the cleaning efficiency.

[0051] Furthermore, when the sweeper is performing a sweeping operation, the first motor 8 is started and drives the main brush 7 to rotate through the first bearing 6. The main brush 7 contacts the ground to realize garbage sweeping. When driving on an uneven road surface, the ups and downs of the ground will push the main brush 7 to move up and down. The main brush 7 drives the swing arm 3 to rotate around the pin 5 on the inner side of the U-shaped frame 2 through the first bearing 6. At this time, the buffer link 9 between the swing arms 3 is linked with the movement of the swing arm 3. The slide rail 11 on the inner wall of the slide groove 10 in the middle of the buffer link 9 slides relative to the limit block 12. The limit block 12 squeezes or stretches the buffer spring 4 between it and the inner wall of the slide rail 11. The buffer spring 4 The elastic deformation can offset part of the impact, preventing the main brush 7 from being damaged due to severe vibration, and ensuring that the main brush 7 always keeps in contact with the ground. At the same time, the sleeve 13 on the upper surface of the outer wall of the swing arm 3 rotates with the swing arm 3, and the pressure spring 14 inside the sleeve 13 is squeezed or stretched by the piston rod 15 and the bottom of the sleeve 13. The elastic force of the pressure spring 14 is transmitted to the bottom of the vehicle body 1 through the piston rod 15, and then reacts on the swing arm 3, providing continuous downward pressure for the swing arm 3, prompting the main brush 7 to fit closely to the ground, and cooperating with the buffering effect of the adaptive adjustment component to further improve the adaptability of the main brush 7 to different road surfaces and the cleaning efficiency.

[0052] See also Figure 1 、 Figure 3 and Figure 4 An embodiment of the present invention provides: a sweeping vehicle with a high-pressure flushing function, including an angle adjustment component and an angle limiting structure, the angle adjustment component includes a fixing seat 16, a worm gear 17 and a worm 18, the fixing seat 16 is fixedly installed at the bottom of the vehicle body 1, and mounting plates 19 are installed on both sides of the bottom surface of the fixing seat 16, and worm gears 18 are installed at both ends of the inner wall of the mounting plate 19. A second motor 20 is fixedly installed at both ends of the worm gear 18, and the worm gear 17 is connected to the worm gear 17 below. A second bearing 21 is embedded in the inner wall of the worm gear 17, one end of the second bearing 21 is fixedly connected to the support frame 22, and the other end is rotatably connected to the bearing seat 23, the side wall of the support frame 22 is fixedly connected to the side brush 24, and the top of the side brush 24 is installed with a third motor 25. The angle limiting structure includes an arc-shaped stopper 26, a limiting bolt 27 and a limiting groove 28. The side of the fixed seat 16 is located outside the second bearing 21 and is fixedly installed with the arc-shaped stopper 26. The arc-shaped stopper 26 extends along the circumferential direction of the worm gear 17. The outer wall of the second bearing 21 is fixedly installed with limiting bolts 27 in the direction corresponding to the two ends of the arc-shaped stopper 26. Limiting grooves 28 are provided at both ends of the arc-shaped stopper 26. An emergency stop button 29 is installed on the bottom surface of the limiting groove 28. This structure can flexibly adjust the angle of the side brush to remove garbage from corners. The limiting structure ensures the safe operation of the equipment.

[0053] Furthermore, the second motor 20 is started, and the second motor 20 drives the worm 18 installed at both ends of the inner wall of the mounting plate 19 to rotate. The rotation of the worm 18 drives the worm wheel 17 connected thereto to rotate. Since a second bearing 21 is nested in the inner wall of the worm wheel 17, the rotation of the worm wheel 17 will drive the second bearing 21 to rotate synchronously, and the support frame 22 fixedly connected to one end of the second bearing 21 rotates therewith, thereby causing the side brush 24 fixedly connected to the side wall of the support frame 22 to change its operating angle. At the same time, the third motor 25 on the top of the side brush 24 is started to provide cleaning power for the side brush 24. During the rotation of the second bearing 21, the limit bolt 27 on its outer wall will move along the inner side of the arc-shaped stopper 26 on the side of the fixing seat 16. The arc-shaped stopper 26 extends along the circumferential direction of the worm gear 17, providing a moving trajectory for the limit bolt 27. When the side brush 24 rotates to a point close to the maximum deflection angle, the limit bolt 27 gradually approaches the limit grooves 28 at both ends of the arc-shaped stopper 26. When the side brush 24 reaches the limit angle, the limit bolt 27 enters the limit groove 28 and triggers the emergency stop button 29 on the bottom of the limit groove 28. The emergency stop button 29 immediately cuts off the power supply of the second motor 20, stopping the worm 18 from rotating, and the worm gear 17 and the second bearing 21 also stop moving, thereby limiting the side brush 24 from continuing to deflect, avoiding structural damage due to excessive adjustment, and ensuring that the side brush 24 is flexibly adjusted within a safe angle range to remove residual garbage in the corner areas.

[0054] See also Figure 1 and Figure 5 The present invention provides an embodiment of a sweeper with a high-pressure flushing function. A mounting frame 30 is installed on the top of the vehicle body 1. A rotating shaft 31 connected to the vehicle body 1 is installed in the middle of the mounting frame 30. The rotating shaft 31 passes through the mounting frame 30 and is rotatably connected to the rotating frame 32 above. Support seats 33 are installed at both ends of the rotating frame 32. The support seats 33 support a high-pressure mist cannon 34. A connecting plate 35 is installed on the bottom surface of the outer wall of the high-pressure mist cannon 34. The middle of the connecting plate 35 is connected to a telescopic push rod 36 by a bolt. The other end of the telescopic push rod 36 is fixed to the rotating frame 32. This structure can realize multi-angle rotation and pitch adjustment of the high-pressure mist cannon, expand the flushing range, and improve the high-pressure flushing effect.

[0055] The support base 33 at both ends of the rotating frame 32 rotates together with the rotating frame 32, and the high-pressure mist cannon 34 on the support base 33 can realize multi-angle rotation in the horizontal direction. When the pitch angle of the high-pressure mist cannon 34 needs to be adjusted, the telescopic push rod 36 is controlled to perform a telescopic action. One end of the telescopic push rod 36 is fixed to the rotating frame 32, and the other end is connected to the connecting plate 35 on the bottom surface of the outer wall of the high-pressure mist cannon 34 by bolts. Therefore, the extension and retraction of the telescopic push rod 36 will drive the connecting plate 35 to move up and down, and the connecting plate 35 in turn drives the high-pressure mist cannon 34 to rotate around the support base 33 to realize the adjustment of the pitch angle. Through the cooperation of these structures installed on the vehicle body 1, a large-scale flushing operation of the high-pressure mist cannon 34 under multi-angle rotation and pitch adjustment is finally realized.

[0056] See also Figure 1 and Figure 6 , an embodiment provided by the present invention: a sweeper with a high-pressure washing function, a high-pressure washing gun 37 is installed on the back of the vehicle body 1, and the high-pressure washing gun 37 is connected to the high-pressure water pump inside the vehicle body 1 through a high-pressure hose 38. A double-suction filtration system is also provided inside the vehicle body 1, and the double-suction filtration system includes a double-filtration structure and a double-fan structure. The double-filtration structure includes two independent filter elements, and the air inlet ends of the two filter elements are connected to the dust suction channel 39 on the back of the vehicle body 1. The double-fan structure includes two independent fans, and the air inlet ends of the two fans are respectively connected to the air outlet ends of the corresponding filter elements, and the air outlet ends of the two fans are commonly connected to the exhaust channel, and the exhaust channel extends to the outside of the vehicle body 1. This structure can accurately wash specific areas, and the double-suction filtration system effectively handles dust and improves the working environment;

[0057] Furthermore, when precise flushing of a specific area is required, the operator can remove the high-pressure flushing gun 37 from the back of the vehicle body 1. The high-pressure flushing gun 37 is connected to the high-pressure water pump inside the vehicle body 1 through a high-pressure hose 38. After the high-pressure water pump is turned on, water flows through the high-pressure hose 38 to the high-pressure flushing gun 37, thereby achieving the flushing operation of the target area. During the cleaning operation, the dust generated will enter the double-suction filtration system through the dust suction channel 39 on the back of the vehicle body 1. The dust first enters the two independent filter elements of the double-filtration structure. After being filtered by the filter elements, the clean air Under the action of the dual-fan structure, the air is transported to the exhaust duct. The two independent fans of the dual-fan structure are respectively connected to the corresponding air outlet ends of the filter elements. When the fans are working, suction is generated to extract the filtered air from the filter elements, and then the filtered air is transported to the outside of the vehicle body 1 through the commonly connected exhaust duct, which effectively avoids the spread of dust and improves the working environment. After the operation is completed, the high-pressure flushing gun 37 is returned to the installation position on the back of the vehicle body 1 to ensure that the high-pressure hose 38 is neatly stored. At the same time, the filter elements of the dual-filter structure can be inspected and cleaned to ensure the continuous and efficient operation of the dual-suction filtration system.

[0058] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The present invention provides an embodiment of a sweeper with a high-pressure flushing function, including an adaptive adjustment component, an angle adjustment component, a high-pressure fog cannon 34 structure and a high-pressure flushing gun 37 structure.

The high-pressure mist cannon structure includes a mounting frame 30, a rotating shaft 31, a rotating frame 32, a support seat 33, a high-pressure mist cannon 34, a connecting plate 35 and a telescopic push rod 36, which can achieve large-scale flushing operations. The high-pressure flushing gun structure includes a high-pressure flushing gun 37 and a high-pressure hose 38, which can accurately flush specific areas. These four parts work together to fully meet the cleaning and flushing needs in different scenarios, significantly improving overall operating efficiency and cleaning quality.

[0059] Furthermore, after starting the sweeper, the first motor 8 drives the main brush 7 to rotate through the first bearing 6. When the main brush 7 encounters ups and downs in the road surface, the swing arm 3 rotates around the connection point on the U-shaped frame 2, and the buffer link 9 moves with the swing arm 3. The limit block 12 slides on the slide rail 11 in the slide groove 10, and the buffer spring 4 expands and contracts to buffer the impact force, ensuring that the main brush 7 always touches the ground. At the same time, the third motor 25 drives the side brush 24 to rotate. If the angle of the side brush 24 needs to be adjusted, the second motor 20 drives the worm 18 to rotate, and the worm 18 drives the worm gear 17 to rotate. The worm gear 17 drives the support frame 22 to rotate through the second bearing 21. The bearing seat 23 assists the second bearing 21 to rotate stably, so that the side brush 24 can be adjusted to the appropriate angle. The fixed seat 16 and the mounting plate 19 provide stable support for the angle adjustment component. When large-scale flushing is required, the rotating frame 32 is driven to rotate through the rotating shaft 31 to make the high-pressure fog cannon 34 on the support seat 33 rotate horizontally. At the same time, the telescopic push rod 36 drives the high-pressure fog cannon 34 to pitch and adjust through the connecting plate 35. The mounting frame 30 provides an installation basis for the high-pressure fog cannon structure. If precise flushing is required, use the high-pressure flushing gun 37 and operate with the water source connected by the high-pressure hose 38. All structures work together to complete the cleaning and flushing work.

[0060] Working principle: First, at the beginning of the operation, check that all systems of the vehicle body 1 are normal and then start the equipment. The first motor 8 drives the main brush 7 to rotate through the first bearing 6, and the swing arm 3 rotates around the pin 5 on the U-shaped frame 2. The limit block 12 on the buffer link 9 slides on the slide rail 11 in the slide groove 10. The buffer spring 4 buffers the impact force of the main brush 7 when it encounters undulating road surfaces. At the same time, the pressure spring 14 in the sleeve 13 applies pressure through the piston rod 15 to ensure that the main brush 7 is closely attached to the ground. The third motor 25 drives the side brush 24 to rotate, and the mounting plate 19 on the fixed seat 16 supports the worm 18. The second motor 20 drives the worm 18 to drive the worm wheel 17 to rotate, so that the second bearing 21 drives the side brush 24 to adjust to the initial working angle through the support frame 22 and the bearing seat 23. The double-suction filtration system is started, and the dust enters the filter element through the dust suction channel 39 and is discharged from the exhaust channel after being processed by the fan;

[0061] Next, during the cleaning process, according to the garbage situation in the corner area, the second motor 20 continues to drive the worm 18 and the worm gear 17 to adjust the angle of the side brush 24. When the side brush 24 deflects to the extreme position, the limit bolt 27 on the second bearing 21 touches the limit groove 28 of the arc-shaped block 26, triggering the emergency stop button 29 to cut off the power supply of the second motor 20 to avoid excessive deflection. At the same time, the high-pressure flushing system can be started according to demand. The rotating shaft 31 on the mounting frame 30 drives the rotating frame 32 to rotate, so that the high-pressure mist cannon 34 on the support seat 33 adjusts the horizontal angle. The telescopic push rod 36 drives the high-pressure mist cannon 34 to adjust the pitch angle through the connecting plate 35 to perform large-scale flushing. You can also use a high-pressure flushing gun 37 and connect it to the water pump through the high-pressure hose 38 to perform precise flushing of specific areas.

[0062] Finally, after the operation is completed, the first motor 8, the third motor 25 and the fan of the double-suction filtration system are turned off in sequence, the main brush 7 and the side brush 24 stop running, and the side brush 24 is reset to the initial position through the worm gear 17, the worm 18 and the second motor 20. The high-pressure flushing gun 37 is put back on the back of the vehicle body 1, the filter of the double-suction filtration system is cleaned, and the status of the main brush 7, the side brush 24, the high-pressure fog cannon 34, the high-pressure flushing gun 37 and other components are checked to ensure that each structure is in a good standby state.

[0063] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
