[0001] The invention relates to the field of road cleaning, and more particularly to a high-pressure spraying device of a road washing and sweeping vehicle. Background Art

[0002] A road sweeper is a special vehicle used for sweeping and cleaning roads. They are usually equipped with high-pressure water jets, vacuum and brush systems, which can effectively remove dust, garbage and dirt from the road surface. The high-pressure spray system is one of the key components of a road sweeper and is widely used in cleaning and maintaining urban roads and public spaces.

[0003] In the process of road cleaning, usually a mechanical brush is used to clean the road surface first, and then a high-pressure sprinkler head is used to flush and clean the cleaned road surface, and the cleaned impurities are flushed to the roadside. However, due to construction or bad weather factors, large pieces of debris such as sand, stones and branches will appear on the road surface. These debris not only affect the normal driving of vehicles, but also get stuck in the mechanical brush during the cleaning process, causing damage to the mechanical brush, resulting in incomplete cleaning and reducing the efficiency of road cleaning, which in turn leads to unsatisfactory road cleaning effects. Summary of the invention

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a high-pressure spray device for a road washing and sweeping vehicle, which can pre-process large debris on the road surface to the roadside, thereby avoiding these debris getting stuck in the mechanical brush during the cleaning process, thereby causing damage to the mechanical brush, and can effectively improve the efficiency of road cleaning, thereby effectively improving the cleaning effect.

[0005] To solve the above problems, the present invention adopts the following technical solutions.

[0010] Furthermore, a circular plate is provided below the sealing plate, the circular plate is fixedly mounted on the inner wall of the circular tube, T-shaped rods are evenly slidably mounted on the circular plate, and a telescopic spring is fixedly mounted between each group of the T-shaped rods and the bottom of the circular plate.

[0011] Furthermore, magnet blocks 1 are evenly fixedly installed on the bottom of the sealing plate, magnet blocks 2 are fixedly installed on the top of each group of T-shaped rods, and each group of magnet blocks 2 is magnetically mounted with adjacent magnet blocks 1.

[0012] Furthermore, drainage holes are evenly arranged at the bottom of the circular frame, and each group of the drainage holes is connected to the inner cavity of the circular frame. Through openings are evenly arranged at the top of the circular frame, and each group of the through openings is connected to the annular frame and the inner cavity of the circular frame.

[0013] Furthermore, a circular plate is arranged above the large gear, and the circular plate is fixedly mounted on the rotating rod. An elastic rod is arranged in contact with the top of the circular plate. There are two groups of elastic rods, and one end of the two groups of elastic rods is fixedly mounted on the rotating rod, and the other end of the two groups of elastic rods is fixedly mounted with an impact ball.

[0014] Furthermore, the impact ball close to one side of the push plate is arranged in contact with one side of the push plate, and the elastic rod close to one side of the push plate is in a bent state.

[0015] Furthermore, the push plate and the drain pipe are both arranged in an oblique shape.

[0016] Furthermore, the inner cavity of the circular tube can only inhale air through the air inlet, and the gas in the inner cavity of the circular tube can only be discharged through the exhaust pipe, thus playing the role of one-way air inlet and outlet.

[0017] Furthermore, the output state of the telescopic spring is a compression state, and the magnetic attraction force of the magnet block 1 and the magnet block 2 is greater than the elastic force of the telescopic spring.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] (1) This solution can scoop up large debris such as sand, stones and branches on the road surface and push them in the direction of the washing and sweeping vehicle through the setting of the push plate. Through the inclined setting of the push plate, while the push plate pushes these large debris to move on the road surface, these large debris will move to the rear side along the inclined surface of the push plate. These large debris will be pushed to the roadside and will not enter the cleaning range of the mechanical brush. At the same time, they will no longer affect the normal driving of the vehicle. This can prevent these debris from getting stuck in the mechanical brush during the cleaning process, thereby causing damage to the mechanical brush. This can effectively improve the efficiency of road cleaning and thus effectively improve the cleaning effect.

[0020] (2) In the process of the sealing plate moving up and down reciprocatingly, the T-shaped rod can reciprocate and hit the top of the annular frame and vibrate it. The shock wave will be transmitted to the mechanical brush. The vibration of the mechanical brush can reduce the adhesion of dust and impurities on it and make it easier to shake them off. The self-cleaning of the mechanical brush can be achieved, which can effectively improve the cleaning effect of the mechanical brush and avoid the situation where the impurities remaining on the mechanical brush affect the road cleaning effect, thereby effectively improving the road cleaning effect.

[0021] (3) This solution uses a mechanical brush to clean the road surface while spraying water through the drainage holes to wet the road surface. In dusty conditions, spraying water can reduce dust flying, while making the road surface clean more thoroughly and more efficiently. In addition, impurities adhering to the mechanical brush can be sprayed off while spraying through the drainage holes. With the cooperation of the vibration of the mechanical brush, the self-cleaning effect of the mechanical brush can be effectively improved, thereby effectively improving the cleaning effect of the mechanical brush on the road surface.

[0032] Also includes:

[0033] A cleaning component, the cleaning component includes a conveying box 5 fixedly installed on one side of the bottom of the mounting plate 1, a fixed pipe 6 is fixedly installed on one side of the conveying box 5, a ring frame 7 is fixedly installed on the bottom end of the fixed pipe 6, a circular frame 23 is rotatably installed on the bottom of the circular frame 7, a mechanical brush 26 is evenly fixedly installed on the bottom of the circular frame 23, a mounting pipe 29 is fixedly installed on the other side of the conveying box 5, a drain pipe 31 is fixedly installed on the bottom end of the mounting pipe 29, a nozzle 32 is evenly fixedly installed on the bottom of the drain pipe 31, a high-pressure pump 28 is fixedly installed on the top of the mounting plate 1, a rotating rod 15 is fixedly installed on the top of the circular frame 23, the rotating rod 15 is rotatably installed with the mounting plate 1, a motor 30 is fixedly installed on the top of the mounting plate 1, the output end of the motor 30 is fixedly installed with the rotating rod 15, and an exhaust component is fixedly installed on one side of the top of the ring frame 7.

[0034] The exhaust assembly includes a round tube 8 fixedly mounted on the top of the annular frame 7, a rotating rod 9 is arranged in the round tube 8, and the two ends of the rotating rod 9 are rotatably mounted with the mounting plate 1 and the annular frame 7 respectively, a reciprocating thread 10 is arranged on the rod wall of the rotating rod 9, a sealing plate 11 is slidably mounted on the inner wall of the round tube 8, and the sealing plate 11 is threadedly mounted with the reciprocating thread 10, a small gear 16 is fixedly mounted on the rod wall of the rotating rod 15, and a large gear 17 is fixedly mounted on the rod wall of the rotating rod 9, and the large gear 17 is connected to the small gear 1 6 meshing installation, rolling grooves 3 are evenly opened on the bottom of the push plate 2, and balls 4 are rollingly installed in the inner cavity of each group of rolling grooves 3, and an air storage cavity 14 is opened in the push plate 2, and each group of rolling grooves 3 is connected with the inner cavity of the air storage cavity 14. An exhaust pipe 13 is fixedly installed on one side of the bottom of the circular tube 8, and the other end of the exhaust pipe 13 passes through the push plate 2 and is connected with the inner cavity of the air storage cavity 14. Intake holes 12 are evenly opened on the sealing plate 11, and each group of intake holes 12 and the inner cavity of the exhaust pipe 13 are installed with a one-way valve.

[0035] First, the device is fixedly installed on the front side of the road washing and sweeping vehicle through the mounting plate 1, and then the pipe of the water pumping end of the high-pressure pump 28 is connected to the water storage tank on the road washing and sweeping vehicle. In the initial state, the drainage end of the high-pressure pump 28 is fixedly installed with the delivery box 5, and then the road washing and sweeping vehicle is used to drive the device to the flat road surface that needs to be cleaned, and the mounting plate 1 is driven by the road washing and sweeping vehicle to move. When the mounting plate 1 moves, it will also drive the push plate 2 to move. The push plate 2 moves on the road surface through the ball bearing 4. The setting of the ball bearing 4 can avoid the situation where the push plate 2 directly contacts the road surface to increase the friction force and avoid wear. The plate 2 is set to scoop up large debris such as sand, stones and branches on the road surface and push them in the direction of the washing and sweeping vehicle. The push plate 2 is set obliquely, and while the push plate 2 pushes these large debris to move on the road surface, these large debris will move to the rear side along the inclined surface of the push plate 2. These large debris will be pushed to the roadside and will not enter the cleaning range of the mechanical brush 26. At the same time, they will no longer affect the normal driving of the vehicle, and these debris can be prevented from getting stuck in the mechanical brush 26 during the cleaning process, thereby causing damage to the mechanical brush 26, which can effectively improve the efficiency of road cleaning and thus effectively improve the cleaning effect.

[0036] The motor 30 is turned on, and the output end of the motor 30 drives the rotating rod 15 to rotate. The rotating rod 15 drives the circular frame 23 to rotate at the bottom of the annular frame 7 while rotating. The circular frame 23 drives the mechanical brush 26 at its bottom to rotate to clean the road surface. The high-pressure pump 28 is turned on. The high-pressure pump 28 pumps the water in the water storage tank through the pumping end, and then discharges it into the delivery box 5 through the drainage end. The water in the delivery box 5 is discharged into the drainage pipe 31 through the installation pipe 29, and then sprayed out through each group of nozzles 32. The multiple groups of nozzles 32 can realize high-pressure spray cleaning of the area cleaned by the mechanical brush 26. The oblique setting of each group of nozzles 32 can realize that the impurities in the area cleaned by the mechanical brush 26 are sprayed to the rear side to the roadside, thereby realizing cleaning of the road surface.

[0037] The output end of the motor 30 drives the rotating rod 15 to rotate, and at the same time drives the small gear 16 to rotate synchronously. When the small gear 16 rotates, it drives the large gear 17 to rotate. Through the cooperation of the large gear 17 and the small gear 16, the fast rotation of the small gear 16 drives the large gear 17 to rotate slowly. When the large gear 17 rotates, it drives the rotating rod 9 to rotate synchronously. When the rotating rod 9 rotates, it drives the sealing plate 11 to move up and down in the inner cavity of the circular tube 8 through the reciprocating thread 10. When the sealing plate 11 moves upward, the inner cavity of the circular tube 8 below the sealing plate 11 will inhale through the suction hole 12, and the external gas will enter the circular tube 8 and be placed below the sealing plate 11. When the sealing plate 11 is in the inner cavity of the circular tube 8 When moving downward, the sealing plate 11 will squeeze the gas in the inner cavity of the circular tube 8 below it and discharge it through the exhaust pipe 13, and the gas in the exhaust pipe 13 will be discharged into the air storage chamber 14, and the gas in the inner cavity of the air storage chamber 14 will be discharged into the inner cavity of each group of rolling grooves 3 and discharged. At this time, the rotating rod 9 rotates through the reciprocating thread 10 to drive the sealing plate 11 to move up and down, so as to realize reciprocating blowing of the inner cavity of the rolling groove 3, which plays a cleaning role, and can prevent the surface of the ball 4 from adhering to impurities during its movement on the road surface, which will increase the rolling friction of the ball 4, and can effectively reduce the friction and improve the rolling effect of the ball 4, thereby effectively improving the service life of the components, and further effectively improving the pushing effect of the push plate 2 on large impurities.

[0038] like Figure 4 and Figure 5 As shown, a circular plate 18 is provided below the sealing plate 11, and the circular plate 18 is fixedly installed on the inner wall of the circular tube 8. T-shaped rods 21 are evenly slidably installed on the circular plate 18, and a telescopic spring 22 is fixedly installed between each group of T-shaped rods 21 and the bottom of the circular plate 18.

[0039] The bottom of the sealing plate 11 is evenly fixed with magnet blocks 19 , and the top of each group of T-shaped rods 21 is fixed with magnet blocks 20 . Each group of magnet blocks 20 is magnetically mounted with adjacent magnet blocks 19 .

[0040] Drain holes 27 are evenly arranged at the bottom of the circular frame 23 , and each group of drainage holes 27 is connected to the inner cavity of the circular frame 23 . Through openings 25 are evenly arranged at the top of the circular frame 23 , and each group of through openings 25 is connected to the inner cavity of the annular frame 7 and the circular frame 23 .

[0041] When the rotating rod 9 rotates through the reciprocating thread 10 to drive the sealing plate 11 to move up and down in the inner cavity of the round tube 8, in the initial state, the magnet block 19 and the magnet block 20 are magnetically attracted together. When the sealing plate 11 moves upward, the sealing plate 11 will pull the magnet block 20 upward through the magnet block 19. When the magnet block 20 moves upward, it will drive the T-shaped rod 21 to move upward and squeeze the telescopic spring 22. When the telescopic spring 22 is squeezed to the maximum extent and the sealing plate 11 continues to move upward, the magnet block 19 will separate from the magnet block 20. Under the action of the telescopic spring 22, the telescopic spring 22 returns to its initial state and pushes the T-shaped rod 21 to drive the magnet block 20 to move downward to the initial position, so that the T-shaped rod 21 can hit the top of the annular frame 7. When the sealing plate 11 moves downward, when the sealing plate 11 When the reciprocating thread 10 moves to the lowermost side, the magnet block 19 and the magnet block 20 enter the magnetic attraction range, so that the magnet block 19 can absorb the magnet block 20 to move upward and be magnetically attracted together, and the magnet block 20 will drive the T-shaped rod 21 to move upward again and squeeze the telescopic spring 22. At this time, during the reciprocating movement of the sealing plate 11 up and down, the T-shaped rod 21 can reciprocate and hit the top of the annular frame 7 and vibrate it, and the shock wave will be transmitted to the mechanical brush 26. The vibration of the mechanical brush 26 can reduce the adhesion of dust and impurities thereon, and facilitate shaking them off, so that the mechanical brush 26 can be self-cleaned, and the cleaning effect of the mechanical brush 26 can be effectively improved, and the situation that the impurities remaining on the mechanical brush 26 will affect the road cleaning effect can be avoided, thereby effectively improving the road cleaning effect;

[0042] The water in the conveying box 5 is discharged into the installation pipe 29 and also into the fixed pipe 6. The water in the fixed pipe 6 is discharged into the annular frame 7. The water in the annular frame 7 is discharged into the inner cavity of the circular frame 23 through multiple groups of openings 25. The water in the circular frame 23 is discharged through each group of drainage holes 27, so that the mechanical brush 26 can clean the road surface while the drainage holes 27 spray water to wet the road surface. In the case of a lot of dust, spraying water can reduce dust flying, and at the same time, it can make the cleaning of the road surface more thorough and more efficient. In addition, impurities adhered to the mechanical brush 26 can be sprayed off while the drainage holes 27 are sprayed. With the cooperation of the vibration of the mechanical brush 26, the self-cleaning effect of the mechanical brush 26 can be effectively improved, thereby effectively improving the cleaning effect of the mechanical brush 26 on the road surface.

[0043] like Figure 1 , Figure 3 and Figure 4 As shown, a circular plate 33 is arranged above the large gear 17, and the circular plate 33 is fixedly installed on the rotating rod 9. An elastic rod 34 is arranged in contact with the top of the circular plate 33. There are two groups of elastic rods 34. One end of the two groups of elastic rods 34 is fixedly installed on the rotating rod 9, and the other end of the two groups of elastic rods 34 is fixedly installed with an impact ball 24.

[0044] The impact ball 24 close to one side of the push plate 2 is arranged in contact with one side of the push plate 2, and the elastic rod 34 close to one side of the push plate 2 is in a bent state.

[0045] When the rotating rod 9 rotates, the elastic rod 34 will drive the impact ball 24 thereon to move synchronously. The rotation of the elastic rod 34 will move on the top of the circular plate 33. The setting of the circular plate 33 can realize the lifting of the elastic rod 34 to prevent the impact ball 24 from driving the elastic rod 34 to bend and fall downward. When the elastic rod 34 drives the impact ball 24 to contact the side wall of the push plate 2, the impact ball 24 will first hit the side wall of the push plate 2. Through the oblique setting of the push plate 2, the impact ball 24 can slide on the side wall of the push plate 2 and squeeze the elastic rod 34. When the impact ball 24 is away from the push plate 2, Under the action of the elastic rod 34, the elastic rod 34 returns to its initial state and drives the impact ball 24 to move to its initial position. At this time, during the rotation of the rotating rod 9, the impact ball 24 can reciprocately impact the side wall of the push plate 2 to generate vibrations on the push plate 2. The vibrations can help break the adhesion between large pieces of debris and the road surface, making it easier for large pieces of debris to be pushed and moved to the roadside, which can effectively improve the pushing effect. At the same time, the vibration of the push plate 2 can reduce the adhesion of dust and impurities on the ball 4, making it easier for the gas in the air storage chamber 14 to clean the impurities on the rolling groove 3 and the ball 4.

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, the push plate 2 and the drain pipe 31 are both arranged in an oblique shape.

[0047] The inner cavity of the circular tube 8 can only be inhaled through the inhalation hole 12, and the gas in the inner cavity of the circular tube 8 can only be discharged through the exhaust pipe 13, which plays the role of one-way air inlet and outlet.

[0048] The output state of the telescopic spring 22 is a compressed state, and the magnetic attraction force of the magnet block 19 and the magnet block 20 is greater than the elastic force of the telescopic spring 22.

[0049] The drain pipe 31 is set obliquely, and the nozzle 32 at the bottom thereof is installed obliquely. Through the oblique coordinated spraying of each group of nozzles 32, impurities in the area cleaned by the mechanical brush 26 can be sprayed to the rear side, and the impurities can be sprayed to the roadside. Through the oblique setting of the push plate 2, large impurities remaining on the road surface can be pushed to the rear side along the inclined surface of the push plate 2, and the large impurities can be pushed to the roadside.

[0050] Working principle: First, the device is fixedly installed on the front side of the road washing and sweeping vehicle through the mounting plate 1, and then the pipe of the water pumping end of the high-pressure pump 28 is connected to the water tank on the road washing and sweeping vehicle. The device will be driven to the flat road surface that needs to be cleaned through the road washing and sweeping vehicle. The road washing and sweeping vehicle will drive the mounting plate 1 to move. When the mounting plate 1 moves, it will also drive the push plate 2 to move. The large impurities on the road surface will be pre-processed and pushed to the roadside, so that large impurities will not appear in the cleaning area of ​​the mechanical brush 26. While the circular frame 23 drives the mechanical brush 26 to rotate to clean the road surface, the drainage hole 27 will spray water to clean the road surface, which improves the cleaning of the road surface. While achieving the self-cleaning effect, the rotating rod 9 is rotating, and the sealing plate 11 moves up and down to blow air into the rolling groove 3 reciprocatingly, which can reduce the rolling friction of the ball 4. Through the cooperation of the magnet block 19 and the magnet block 20, under the action of the telescopic spring 22, the T-shaped rod 21 can reciprocately impact the annular frame 7 and vibrate the mechanical brush 26, so as to improve the self-cleaning effect of the mechanical brush 26. Through the cooperation of the elastic rod 34 and the impact ball 24, the push plate 2 is reciprocated and vibrates, which makes it easier for the push plate 2 to push large impurities. Through each group of nozzles 32, the impurities in the area cleaned by the mechanical brush 26 will be flushed to the roadside.

[0051] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
