Description

Technical Field

[0001] The present application relates to the technical field of road construction, and in particular, to a road cleaning device. Background Art

[0002] Road construction devices refer to all machinery required in the entire road construction and maintenance, including preliminary surveying equipment, excavation equipment in the early stage of construction, maintenance equipment in the later stage of construction, and a series of mechanized tools that replace manual operations.

[0003] A road cleaning device is a road maintenance device that achieves the effect of cleaning the ground by collecting and cleaning the dust on the road surface. Currently, general road cleaning devices generally include a vehicle body, a transmission device, a cleaning device, and a spraying device. In order to reduce the dust flying caused by cleaning, the road surface is first simply wetted by the spraying device. However, after the wetted dust is cleaned and collected by the cleaning device, it is easy to adhere to the collection box of the cleaning device, making it difficult for the cleaning device to unload materials, and it is easy to block the cleaning device after a certain period of use, affecting the cleaning effect. Summary of the Invention

[0004] In order to improve the unloading efficiency of the collection box and reduce the adhesion of wet dust and soil, the present application provides a road cleaning device.

[0005] The road cleaning device provided by the present application adopts the following technical solution: A road cleaning device includes a mobile vehicle body, a transmission system for driving the mobile vehicle body to travel, a cleaning device provided on the mobile vehicle body, and a spraying device for wetting the ground. The cleaning device includes a dust suction box body provided on the mobile vehicle body and a collection box body rotatably installed in the dust suction box body and communicated with the dust suction box body. It further includes a scraper assembly for scraping the collection box body. The scraper assembly includes a fixed frame body provided on the dust suction box body and a scraping plate. The scraping plate has a scraping surface that abuts against the bottom of the collection box body, and the scraping surface is located on the side of the collection box body away from the dust suction box body.

[0006] By adopting the above technical solution, when using the above road cleaning equipment, the drive system drives the mobile vehicle body to travel along the road. When the mobile vehicle is traveling, the spraying device and the cleaning device are started. Road impurities such as dust, soil, and gravel on the road surface are first preliminarily wetted by the spraying device to reduce dust flying, and then are swept and collected by the cleaning device. After the cleaning is completed, the mobile vehicle travels to the unloading point, and the collecting box rotates, so that the side wall openings corresponding to the collecting box and the dust suction box face the ground. The road impurities in the dust suction box automatically fall under the action of gravity. Through the arrangement of the scraper assembly, when the collecting box rotates, the scraping plate is in a relatively static state, and the scraping surface abuts against the bottom of the collecting box, so that when the collecting box rotates and unloads materials, the scraping plate can simultaneously scrape the wet impurities adhering to the inner wall of the collecting box. When the collecting box rotates to the maximum angle, the scraping plate covers the side wall opening of the collecting box, ensuring that all the impurities in the collecting box can be unloaded.

[0007] Optionally, an arc-shaped abutting surface for the scraping surface to abut against is provided in the collecting box, and the center of the arc-shaped abutting surface is coaxial with the rotation axis of the collecting box. When the collecting box rotates to unload materials, the scraping surface always fits against the arc-shaped abutting surface.

[0008] By adopting the above technical solution, the scraping surface of the scraping plate abuts against the arc-shaped abutting surface, and the center of the arc-shaped abutting surface is coaxial with the rotation axis of the collecting box, so that when the collecting box rotates, the scraping surface can always be in a state of abutting against the bottom wall of the collecting box, ensuring the scraping effect of the scraping plate on the bottom wall of the collecting box when the collecting box rotates and improving the unloading effect of impurities.

[0009] Optionally, a plurality of spaced tooth grooves are provided at intervals on the scraping surface of the scraping plate, and spaced arc bars corresponding to the spaced tooth grooves one by one are provided on the arc-shaped abutting surface of the collecting box. Scraping bristles are provided on the bottom walls of adjacent spaced tooth grooves, and spaced arc rods sleeved with the scraping plate are provided on adjacent spaced arc bars.

[0010] By adopting the above technical solution, due to the arrangement of the spaced tooth grooves and the spaced arc bars, adjacent spaced arc bars also form grooves. Larger-sized gravel in the road impurities cannot enter these grooves, realizing the screening of larger-sized impurities and fine stones, so that when the collecting box unloads materials, the situation where larger-sized gravel is not easy to fall can be reduced. In addition, due to the sleeved cooperation between the spaced arc rods and the scraping plate, one end of the scraping plate is fixed to the dust suction box, and the other end has a sliding fit with the collecting box, ensuring the stability of the scraping plate during scraping and unloading.

[0011] Optionally, the fixed frame body includes a first frame body fixed to the inner top wall of the dust suction box and a second frame body connecting the first frame body. A vibration component and a blowing component for driving the scraping plate to vibrate are provided on the second frame body.

[0012] By adopting the above technical solution, the structural composition of the fixing frame body is disclosed. The fixing frame body is fixed to the dust suction box body through the first frame body, ensuring the overall structural strength and stability of the scraper assembly. The two ends of the second frame body are respectively fixed to the scraping plate and the first frame body, playing an effect of spaced connection. The vibration assembly is arranged on the second frame body, which can drive the scraping plate to rotate when the collecting box body discharges materials. Since the scraping plate and the collecting box body are matched by spaced arc strips, the vibration of the scraping plate can drive the overall vibration of the collecting box body, thereby realizing the effect of vibrating discharging. The setting of the air blowing assembly can dry the wet sundries in the collecting box body and reduce the resistance of the scraping plate.

[0013] Optionally, the vibration assembly includes a vibration driving member, an eccentric driving rod eccentrically fixed to the output shaft of the vibration driving member, and a moving rod connecting the eccentric driving rod. The moving rod is perpendicular to the vibration driving member. The scraping plate is provided with a guide sleeve for restricting the moving rod. The scraping plate is provided with a sliding part slidably matched with the second frame body. The second frame body is provided with a sliding groove arranged with the sliding part, and an elastic member abutting against the sliding part is arranged in the sliding groove.

[0014] By adopting the above technical solution, the setting of the vibration assembly is specifically disclosed. When the collecting box body rotates, the vibration driving member is started to drive the eccentric driving rod to rotate eccentrically. The eccentric driving rod is connected to the moving rod. Under the limiting action of the guide sleeve, the moving rod makes a linear motion. The moving rod pushes the guide sleeve at intervals. The scraping plate is slidably matched with the second frame body and is connected through an elastic member, that is, the pushing of the moving rod on the guide sleeve causes the overall vibration of the scraping plate. The structure of the above vibration assembly is convenient to assemble and realizes the vibration of the collecting box body while scraping materials.

[0015] Optionally, the extending direction of the elastic member is parallel to the rotation axis of the collecting box body. The scraping plate is provided with a strip-shaped hole sleeved and matched with the spaced arc strip, and the extending direction of the strip-shaped hole is parallel to the axis of the elastic member.

[0016] By adopting the above technical solution, the arrangement direction of the elastic member is limited. The direction of the elastic member is parallel to the rotation axis of the collecting box body, so that the vibration direction of the scraping plate is perpendicular to the falling direction of the impurities. Through the cooperation of the spaced tooth grooves and the spaced arc strips, the abutting area between the scraping plate and the collecting box body is increased, improving the vibration effect.

[0017] Optionally, the bottom of the dust suction box body is provided with a dust suction through hole for dust and gravel to enter, and a cleaning brush is rotatably installed in the dust suction through hole. A guiding baffle is arranged between the dust suction through hole and the fixing frame body of the dust suction box body, and the dust and gravel sucked by the cleaning brush are guided to the collecting box body through the guiding baffle.

[0018] By adopting the above technical solution, when the mobile vehicle body moves, the cleaning brush rotates, and road impurities enter the collection box through the dust suction through holes. Through the setting of the guiding baffle, the probability of impurities splashing onto the fixed frame body can be reduced, the cleanliness of the first frame body and the second frame body can be ensured, the maintenance cycle can be reduced, and at the same time, it plays a guiding role in transporting impurities to the collection box.

[0019] Optionally, the air blowing assembly includes an air blowing source and a plurality of groups of air pipes connected to the air blowing source. The plurality of groups of air pipes correspond to the spaced arc bars one by one. The end of the air pipe extends towards the spaced arc bar, and the axis of the output hole of the air pipe is tangent to the arc-shaped contact surface.

[0020] By adopting the above technical solution, the setting of the air blowing assembly enables the inner wall of the collection box to be blown when the collection box collects impurities or rotates for discharging, which plays a role in drying the impurities and blowing the dust in the grooves of the adjacent spaced arc strips, improving the discharging effect.

[0021] Optionally, the mobile vehicle body is provided with a lifting assembly for driving the cleaning device to lift. The lifting assembly includes a lifting fixed frame fixed to the mobile vehicle body, a lifting moving frame slidably mounted on the lifting fixed frame, and a lifting driving member for driving the lifting moving frame to lift.

[0022] By adopting the above technical solution, the setting of the lifting assembly realizes the lifting of the mobile vehicle body in the vertical direction, facilitating the cleaning equipment to discharge road impurities to a discharging area at a certain height, and improving the practicality of discharging.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: 1. Through the setting of the scraping plate assembly in the present application, when the collection box rotates for discharging, the scraping plate simultaneously scrapes the wet impurities adhering to the inner wall of the collection box, reducing the probability of road impurities adhering to the inside of the collection box; 2. In the present application, through the spaced arc bar and the scraping plate, the stability of the scraping plate during scraping and discharging is ensured; 3. Through the setting of the vibration assembly in the present application, the scraping plate vibrates in the horizontal direction while scraping, further improving the discharging efficiency.

In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0033] The following will further elaborate on this application in conjunction with the attached Figure 1-7 drawings.

[0034] An embodiment of this application discloses a road cleaning device.

[0035] Referring to Figure 1 , a road cleaning device includes a moving vehicle body 1, a transmission system 2 for driving the moving vehicle body 1 to travel, a cleaning device 3, and a spraying device 4. The transmission system 2 is a diesel or gasoline engine, which is connected to the wheels of the moving vehicle body 1 through a transmission structure. The cooperation between the transmission system 2 and the moving vehicle body 1 is the same as that in the prior art, and will not be described in detail in this application.

[0036] The cleaning device 3 is arranged on one side of the front wheels of the moving vehicle body 1 and is used for cleaning and collecting road impurities such as dust, soil, and gravel on the road. The spraying device 4 includes a first spraying assembly 41 and a second spraying assembly 42 respectively arranged at both ends in the moving direction of the moving vehicle body 1. The first spraying assembly 41 is used for wetting the road surface before the cleaning device 3 cleans to reduce the flying of dust; the second spraying assembly 42 is used for high-pressure flushing of the road surface after the cleaning is completed. In this embodiment, the road impurities include dust, stones, mud, cinder, etc. The structures of the two spraying assemblies are the same, and both include a water storage tank 411, a main water pipe 412 communicating with the water storage tank 411, and a plurality of spray heads 431 spaced apart on the main water pipe 412.

[0037] Referring to Figure 1 and Figure 2 , the cleaning device 3 includes a dust suction box body 31 arranged on the moving vehicle body 1 in a lifting manner, a collection box body 32 rotatably installed on the dust suction box body 31 and communicating with the dust suction box body 31, and a scraper assembly 33.

[0038] A lifting assembly 11 for driving the lifting of the dust suction box body 31 is provided on the moving vehicle body 1. The lifting assembly 11 includes a lifting fixing frame 111 fixed to the moving vehicle body 1, a lifting moving frame 112 slidably installed on the lifting fixing frame 111, and a lifting driving member 113 for driving the lifting of the lifting moving frame 112. The lifting driving member 113 is a hydraulic cylinder, which is fixedly installed at the bottom of the lifting fixing frame 111, and the output shaft is fixed to the lifting fixing frame 111.

[0039] The outer side wall of the dust suction box body 31 is fixed to the lifting moving frame 112. The lifting of the lifting moving frame 112 drives the overall lifting of the cleaning device 3, so that the road cleaning equipment can adjust the height of the cleaning device 3 according to the height of the discharging area, improving the practicability.

[0040] The dust suction box body 31 is integrally a rectangular box body, and its length direction is perpendicular to the width direction of the moving vehicle body 1. The bottom of the dust suction box body 31 has a dust suction through hole 311 communicating with the inner cavity, and one side of the dust suction box body 31 away from the lifting assembly 11 has a through hole. A cleaning brush 312 is rotatably installed at the dust suction through hole 311 of the dust suction box body 31, and the axis of the cleaning brush 312 is parallel to the length direction of the dust suction box body 31. The cleaning brush 312 is used to abut against the bottom surface to be cleaned. A rotating motor for driving the cleaning brush 312 to rotate is installed on the side wall of the dust suction box body 31, and its rotating direction is opposite to the rotating direction of the wheels of the moving trolley. Among them, auxiliary brushes 36 for increasing the cleaning range are also provided on the opposite side walls of the collection box body 32, and the auxiliary brushes 36 are driven by motors.

[0041] The collection box body 32 is also integrally a rectangular box body, and its side wall has a feeding through hole 321 communicating with the dust suction box body 31. The outer side of the top of the collection box body 32 is connected to the dust suction box body 31 through a hinge structure. The hinge structure includes hinge seats 313 respectively provided on the tops of the collection box body 32 and the dust suction box body 31 and corresponding to each other, and rotating driving members 314 provided on the opposite side walls of the dust suction box body 31.

[0042] The rotating driving member 314 is a hydraulic cylinder, one end of its cylinder body is hinged and installed on the dust suction box body 31, and one end of the piston output shaft is hinged and installed on the collection box body 32. When discharging is required, first move the cleaning device 3 upward to a certain height through the lifting assembly 11, and then start the rotating driving member 314 to make the collection box body 32 rotate along the axis of the hinge seat 313, and the side wall opening of the collection box body 32 is inclined downward as a whole, so that the road impurities in the collection box body 32 automatically fall under the action of gravity.

[0043] The scraper assembly 33 includes a fixed frame body 331 fixed to the dust suction box body 31 and a scraping plate 332 slidably mounted on the fixed frame body 331 and extending into the collection box body 32. The scraping plate 332 is entirely located on the side of the collection box body 32 away from the dust suction box body 31. A collection frame 322 for receiving road impurities is detachably arranged in the collection box body 32, and the size of the scraping plate 332 matches the inner cavity cross-section of the collection frame 322.

[0044] Referring to Figure 2 and Figure 3 , the bottom of the scraping plate 332 has a scraping surface 3321 abutting against the collection frame 322, and the inner bottom wall of the collection frame 322 has an arc-shaped abutting surface 3221 mating with the scraping surface 3321. The center of the arc-shaped abutting surface 3221 is coaxial with the rotation axis of the hinge seat 313, and the scraping surface 3321 is an arc surface protruding towards the arc-shaped abutting surface 3221. Therefore, when the collection box body 32 rotates, the opposite side walls and the bottom of the scraping plate 332 are always in an abutting state with the collection frame 322, so that when the road impurities automatically fall due to their own gravity, the impurities adhering to the inside of the collection frame 322 can be scraped off under the scraping action of the scraping plate 332.

[0045] The scraping plate 332 is provided with a plurality of spaced tooth grooves 3322 at intervals on the scraping surface 3321. The cross-section of the spaced tooth grooves 3322 can be semi-circular or rectangular. In this embodiment, the cross-section of the spaced tooth grooves 3322 is rectangular. The collection frame 322 has spaced arc strips 3222 corresponding to the spaced tooth grooves 3322 one by one on the arc-shaped abutting surface 3221, and the spaced tooth grooves 3322 and the spaced arc strips 3222 are inserted and matched.

[0046] An adjacent spaced tooth groove 3322 forms a spaced plug 3323. The scraping plate 332 is provided with scraping bristles at the bottom and opposite side walls of the spaced plug 3323 to improve the scraping effect on the inner wall of the collection frame 322 when the collection box body 32 rotates. Among them, a spaced arc groove 3223 is formed between adjacent spaced arc strips 3222, and the collection frame 322 is provided with a spaced arc rod 3224 sleeved and matched with the scraping plate 332 in the collection arc groove. The spaced arc rod 3224 and the arc-shaped abutting surface 3221 are concentrically arranged, and the spaced plug 3323 has a through hole penetrating through both end faces for the spaced arc rod 3224 to pass through.

[0047] The fixed bracket includes a first frame body 3311 fixed to the inner top wall of the dust suction box body 31 and a second frame body 3312 connected to the first frame body 3311. The first frame body 3311 is an L-shaped plate with an angle greater than 90 degrees, and the angle is located on the side away from the cleaning brush 312. The second frame body 3312 is a rectangular plate arranged horizontally. One side in its length direction is fixedly connected to the first frame body 3311, and the other side in its length direction is connected to the scraping plate 332. Both sides in the width direction of the second frame body 3312 are fixed to the inner side wall of the dust suction box body 31, so as to further improve the overall structural strength of the scraping plate assembly 33.

[0048] Referring to Figure 4 and Figure 5 , the scraping plate 332 is an overall telescopic plate structure, which includes a scraping lower plate 3325 and a scraping upper plate 3324. The scraping lower plate 3325 and the scraping upper plate 3324 are connected by a spring. An elevating drive member for driving the scraping lower plate 3325 to move downward is provided on the back of the scraping upper plate 3324. In this embodiment, the elevating drive member is an elevating cylinder. A limiting side rod 3326 is provided on the side wall of the scraping lower plate 3325, and a limiting slideway 3225 adapted to the limiting side rod 3326 is provided on the inner wall of the collection box 322. The limiting slideway 3225 includes two arc-shaped slideways 3226 concentric with the arc-shaped abutting surface 3221 and transition slideways 3227 at both ends. When the limiting side rod 3326 is located in the lower slideway, the elevating drive member drives the scraping lower plate 3325 to press tightly against the collection box 322, and the spring between the scraping lower plate 3325 and the scraping upper plate 3324 is in a compressed state. The transition slideway 3227 near the opening side of the collection box 322 has a transition vertical surface 32271 for guiding the limiting side rod 3326 to move to the upper slideway, and the other transition slideway 3227 has a transition arc surface 32272 for guiding the limiting side rod 3326 to move to the lower slideway.

[0049] Referring to Figure 4 and Figure 5 , in order to improve the scraping effect of the scraping plate, a vibration assembly 34 for driving the scraping plate 332 to vibrate is provided on the second frame body 3312. The vibration assembly 34 includes a vibration drive member 341 provided on the second frame body 3312, an eccentric drive rod 342, and a moving rod 343. The vibration drive member 341 is a rotating motor in the prior art, and a drive shaft is coaxially fixed to its output shaft. The second frame body 3312 has a rotating bearing seat for the other end of the drive shaft to rotate.

[0050] An eccentric mounting groove for installing the eccentric drive rod 342 is provided in the middle of the drive shaft. One end of the eccentric drive rod 342 is inserted into the eccentric mounting groove and is eccentrically fixed to the drive shaft. The other end of the eccentric drive rod 342 and the moving rod 343 are rotatably connected by a pin shaft.

[0051] Combined with Figure 6 and Figure 7, the scraping plate 332 has a sliding portion 3327 slidably engaged with the second frame body 3312 on a side away from the scraping surface 3321 and a guide sleeve 3328 located at the top of the second frame body 3312. The end of the guide sleeve 3328 has an axial movement groove that restricts the rotation of the moving rod 343, so that when the eccentric drive rod 342 rotates eccentrically, the moving rod 343 can move horizontally along the axial movement groove.

[0052] A spring groove is also formed in the end face of the moving rod 343, and a spring member is arranged in the spring groove. The two ends of the spring member are respectively connected to the moving rod 343 and the inner bottom wall of the guide sleeve 3328. When the moving rod 343 moves towards the guide sleeve 3328, the spring member is gradually compressed.

[0053] The side wall of the second frame body 3312 has a sliding groove 33121 for slidably arranging the sliding portion 3327 in the horizontal direction, and the second frame body 3312 is provided with an elastic member 33122 in the sliding groove 33121. The elastic member 33122 is a spring, and its arrangement direction is parallel to the axis of the spring member.

[0054] In this embodiment, the second frame body 3312 has at least two groups of sliding portions 3327, and the sliding portions 3327 are installed in the sliding groove 33121 in a limited manner. A limiting edge 33271 is rotatably installed on the side wall of the sliding portion 3327, and the cross section of the limiting edge 33271 is triangular. The limiting edge 33271 and the sliding portion 3327 are connected by a spring, and the side wall of the second frame body 3312 in the sliding groove 33121 has a limiting groove (not marked in the figure) for the limiting edge 33271 to be inserted in a limited manner. In this embodiment, the extending directions of the elastic member 33122 and the spring member are both parallel to the rotation axis of the collection box body 32, so that when the vibration drive member 341 is started, the scraping plate 332 as a whole vibrates back and forth along the length direction of the second frame body 3312. Through the sleeving cooperation of the spacer plug 3323 and the spacer arc rod 3224, the scraping plate 332 drives the collection frame 322 to also vibrate to a certain extent, thereby improving the blanking efficiency of road impurities. Refer to Figure 4 , the through hole for the sleeving cooperation of the spacer plug 3323 and the spacer arc bar 3222 is a strip-shaped hole 33231, and the extending direction of the strip-shaped hole 33231 is parallel to the vibration direction. A vertical strip groove extending in the height direction is also provided in the middle of the strip-shaped hole 33231, so that the upper scraping plate 3324 and the lower scraping plate 3325 can slide relative to each other.

[0055] In order to reduce the humidity of the impurities in the collection box 322, a blowing assembly 35 is further provided on the second frame body 3312. The blowing assembly 35 includes a blowing air source 351 and a plurality of groups of air pipes 352 connected to the blowing air source 351. The top of the dust collection box body 31 has a ventilation hole. The number of the air pipes 352 is the same as the number of the spacer plugs 3323, and they extend along the direction of the scraping plate 332 to the spacer arc groove 3223. The whole air pipe 352 is located on the opening side of the scraping plate 332 away from the collection box 322, and the blown gas passes through the strip-shaped holes and is conveyed along the spacer arc groove 3223. Among them, a resistance wire, a heater, etc. can be arranged in the blowing air source 351 as a heat source so that the blown gas has a certain temperature.

[0056] Referring to Figure 4 and Figure 5 , a guiding baffle 315 is further fixed at the bottom of the fixed frame body 331 of the dust collection box body 31. The guiding baffle 315 forms a channel for conveying road impurities between the dust collection box body 31 and the collection box body 32, so that the road impurities inhaled by the cleaning brush 312 can enter the collection box body 32 along the guiding baffle 315, and at the same time, the influence of the road impurities on the fixed frame body 331 is reduced.

[0057] The implementation principle of a road cleaning device according to an embodiment of the present application is as follows: The moving vehicle body 1 travels along the road surface under the action of the transmission system 2, and the road impurities are brought into the collection box 322 under the rotation of the cleaning brush 312; after the collection is completed, the moving trolley moves to the unloading area, and the height of the cleaning device 3 is adjusted according to the unloading height; The collection box body 32 is rotated so that the road impurities in the collection box 322 automatically fall under the action of gravity. At the same time, the scraping plate 332 always abuts against the arc-shaped abutting surface 3221, so that the wet impurities adhering to the inner wall of the collection box 322 are scraped off at the same time; when the collection box body 32 rotates, the vibration assembly 34 and the blowing assembly 35 are started at the same time, so that the scraping plate 332 and the collection box 322 vibrate synchronously, and gas is conveyed into the spacer arc groove 3223; after a pouring is completed, the collection box body 32 is reset, and the limiting side rod 3326 moves to the upper arc-shaped slideway 3226 under the action of the first transition inclined surface. At this time, the scraping surface 3321 and the arc-shaped abutting surface 3221 are in an interval state until the limiting side rod 3326 moves to the lower arc-shaped slideway 3226 again under the action of the second transition inclined surface, and the scraping surface 3321 and the arc-shaped abutting surface 3221 are reattached.

[0058] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
