Description

Technical Field

[0001] The invention relates to the technical field of road washing, and in particular to a construction site road washing device and method. Background Art

[0002] In the daily operation of construction sites, the cleanliness of the roads is directly related to the quality of the entire construction environment. Due to the high frequency of construction vehicles, a large amount of dust, sand and various types of construction waste are constantly accumulated on the roads of construction sites. These impurities not only seriously affect the appearance of the roads and make the construction site look messy, but also increase the risk of slipping and tripping of passing vehicles and pedestrians, threatening personal safety. More importantly, the dust raised by vehicles during driving is scattered wantonly, greatly deteriorating the air quality of the surrounding environment and posing a potential hazard to the health of construction workers and nearby residents. Therefore, regular flushing of construction site roads has become an inevitable requirement to maintain a clean construction environment and ensure the safety and health of personnel.

[0003] At present, the traditional method of road washing at construction sites has obvious defects. After washing, a large amount of water, carrying dust, sand and gravel as well as solid waste generated by construction, is washed to the roadside. The green area on the roadside is an important part of improving the ecology around the construction site and beautifying the landscape, but it has suffered heavy damage due to these sewage and debris. At the same time, the chemical additives, construction waste and other harmful substances contained in the debris seep into the soil with the water flow, changing the original pH and fertility structure of the soil, causing irreversible damage to the roots of green plants, and even killing some green plants, greatly reducing the green landscape effect.

[0004] An in-depth analysis of the traditional flushing method reveals its essence of "treating the symptoms but not the root cause". Most of the existing road flushing equipment only focuses on cleaning the surface of the road. By increasing the water pressure and the number of nozzles, the visible dirt on the road is temporarily removed, but the problem of where the water and debris go after flushing is not fundamentally solved. The limitations of the equipment design principle make it impossible for them to effectively collect and properly dispose of the waste after flushing, allowing sewage and debris to be discharged to the roadside at will, and constantly exacerbating the damage to greening. In order to alleviate this problem, some construction sites have to arrange manual cleaning of roadside greening after flushing. However, manual cleaning not only consumes a lot of manpower and time costs, but also due to limited cleaning methods, it is difficult to completely remove pollutants that have penetrated into the soil and attached to the deep layers of the leaves, and it is impossible to restore the healthy state of greening from the root, and the treatment effect is difficult to last. In the long run, not only the cost of greening maintenance remains high, but the ecological environment around the construction site is also facing the risk of continued deterioration. Therefore, the development of a construction site road flushing equipment and method has become an urgent task in the field of construction. Summary of the invention

At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of description, and are not used to limit the scope of the implementation of the present invention. Changes or adjustments in their relative relationships should also be regarded as the scope of the implementation of the present invention without substantially changing the technical content.

[0024] The present invention provides a technical solution: a construction site road washing equipment provided by the present invention mainly includes a shell 1 with an opening at the bottom, and key components such as a water impact mechanism 2, a guide groove 3, a transfer mechanism 4, a waste receiving groove 5 and a knocking mechanism 6 are integrated in the shell. The components work together to achieve efficient and environmentally friendly washing operations on the construction site roads.

[0025] The core of the water impact mechanism 2 is the first belt 201 that can circulate in the horizontal direction. The first belt 201 realizes cyclic transmission through two transmission rollers 204 rotatably mounted on the inner wall of the housing 1, and the transmission rollers 204 are driven by a first motor 216 fixedly mounted on the side wall of the housing 1. U-shaped frames 205 are fixed at intervals on the first belt 201, and the rotating rod 202 is rotatably connected to the side wall of the U-shaped frame 205. A mounting block 206 is fixedly connected to the outer wall of the rotating rod 202 located inside the U-shaped frame 205, and the fan-shaped nozzle 203 is fixedly mounted on the bottom of the mounting block 206, so that the fan-shaped nozzle 203 can adjust the water spraying angle as the rotating rod 202 rotates.

[0026] In order to realize the automatic water spraying and angle adjustment of the fan-shaped sprinkler 203, the outer wall of the rotating rod 202 near the end is fixedly connected with a baffle 207, and the outer wall of the rotating rod 202 is sleeved with a first torsion spring 208, and the two ends of the first torsion spring 208 are respectively fixedly connected to the U-shaped frame 205 and the baffle 207. The side wall of the U-shaped frame 205 is also fixedly connected with a stopper 209 that is blocked by the baffle 207, so as to limit the rotation range of the rotating rod 202. The outer wall of the rotating rod 202 near one end is fixedly connected with a wedge block 210, and the inner wall of the housing 1 located below the first belt 201 is fixedly connected with a guide bar 211. One end of the guide bar 211 is provided with an inclined surface that slides with the wedge surface of the wedge block 210, and the other end is an upward arc setting, and the bottom of the guide bar 211 can slide with the wedge surface of the wedge block 210.

[0027] Several water pipes 212 are fixedly connected in the first belt 201, and one end of the water pipe 212 is open and the port is flush with the side wall of the first belt 201. A water cavity 213 is fixedly embedded in the side wall of the shell 1 near the port of the water pipe 212. The water cavity 213 is located on one side of the shell 1, and the port at the opening is close to the side wall below the first belt 201 and is slidably connected with it. The side wall of the water cavity 213 located outside the shell 1 is connected with an interface 214, which is in the shape of a strip, and the end located above the guide groove 3 is set in an arc shape following the turning point of the first belt 201. A check valve 215 is installed on the inner wall at the port of the water pipe 212 to prevent the water in the water pipe 212 from flowing back. The water pipe 212 is connected to the fan-shaped nozzle 203 through a hose.

[0028] When the first motor 216 drives the transmission roller 204 to rotate, the first belt 201 circulates. When the fan-shaped nozzle 203 follows the first belt 201 and runs below it, the port of the water pipe 212 enters the water chamber 213. Under the water pressure in the water chamber 213, the check valve 215 opens, and the water in the water chamber 213 enters the water pipe 212, so that the fan-shaped nozzle 203 sprays water obliquely toward the ground. As the first belt 201 continues to run, the fan-shaped nozzle 203 moves toward the direction of the guide groove 3, and the wedge block 210 moves to the guide bar 211. The wedge surface of the wedge block 210 slides with the inclined surface of the end of the guide bar 211, so that the wedge block 210 rotates with the rotating rod 202 as the axis, driving the fan-shaped nozzle 203 to rotate. Then the bottom of the guide bar 211 and the wedge-shaped surface of the wedge block 210 are slidably matched, so that the fan-shaped nozzle 203 forms an obtuse angle with the water flow impact direction of the guide groove 3, and the impact direction is obliquely upward, so that the water flow and dust on the ground are flushed to the inclined trough 402. When the wedge block 210 leaves the guide bar 211, under the action of the first torsion spring 208, the rotating rod 202 returns to its original position, the baffle plate 207 is blocked by the stop rod 209, and at the same time, the port of the water pipe 212 leaves the water cavity 213, the check valve 215 is closed, and the fan-shaped nozzle 203 stops spraying water.

[0029] In order to ensure that the water impact mechanism 2 has a stable water source, a water tank 7 is fixedly installed on the inner wall of the housing 1 above the water impact mechanism 2, and a water injection port 701 connected to the inside of the water tank 7 is installed on the top of the water tank 7, and the water injection port 701 vertically passes through the top surface of the housing 1. A first water pump 8 is fixedly installed on the side wall of the housing 1, and the extraction end of the first water pump 8 is connected to the side wall of the water tank 7 near the bottom, and the water outlet end is connected to the interface 214, which is used to extract water from the water tank 7 and supply water to the water cavity 213.

[0030] The guide groove 3 is rotatably connected to the side wall of the housing 1 through the connecting shaft 301, and the connecting shaft 301 is rotatably connected to the side wall of the housing 1 and extends to the outside. The outer wall of the connecting shaft 301 located at one end outside the housing 1 is sleeved with a second torsion spring 302, and the two ends of the second torsion spring 302 are respectively fixedly connected to the connecting shaft 301 and the side wall of the housing 1. A rubber strip 303 is fixedly connected to the top port of the guide groove 3, and the bottom of the rubber strip 303 near the top is pressed against the side wall of the second belt 401, which is used to guide the water flow impacted by the fan-shaped nozzle 203.

[0031] During road washing, the bottom of the lowest end of the guide groove 3 is chamfered, and the bottom surface of the chamfer is close to the ground. When debris passes through the bottom of the chamfer of the guide groove 3, the guide groove 3 rotates with the connecting shaft 301 as the axis. After the debris passes, the guide groove 3 returns to its original position under the action of the second torsion spring 302, and the bottom of the chamfer is close to the ground again, ensuring that the water flow can be smoothly introduced into the inclined trough 402.

[0032] The transfer mechanism 4 is mainly composed of two drive shafts 403 that are rotatably connected to the side wall of the housing 1 and are arranged up and down, four sprocket wheels 404 that are fixedly sleeved on the outer wall of the drive shaft 403, two chains 405 that mesh with the sprocket wheels 404, and a second belt 401. The two side walls of the second belt 401 are fixedly connected to the side walls of the two chains 405, respectively, and a second motor 406 that is axially connected to one end of the drive shaft 403 is fixedly installed on the side wall of the housing 1.

[0033] The second motor 406 drives the chain 405 to run through the drive shaft 403 and the sprocket 404, thereby driving the second belt 401 to circulate in the vertical direction. The outer wall of the second belt 401 is provided with a plurality of evenly arranged inclined troughs 402. When the inclined troughs 402 follow the second belt 401 to run to one side of the guide trough 3, the ports face upward to receive the water-dust mixed wastewater guided by the guide trough 3; when running to the side of the waste receiving trough 5, the ports face downward to facilitate pouring the wastewater into the waste receiving trough 5.

[0034] The side wall of the waste receiving trough 5 is slidably connected to the outer wall of the second belt 401, and an arc groove 501 is provided at the bottom thereof. The bottom between the arc groove 501 and the second belt 401 is inclined to guide the solid waste into the arc groove 501. A third motor 502 is fixedly installed on the side wall of the housing 1, and the output end shaft of the third motor 502 is connected to an auger blade 503 provided in the arc groove 501. An electric gate valve 504 is fixedly installed on a side wall of the housing 1 away from the third motor 502, and the electric gate valve 504 is connected to the arc groove 501 at the end of the auger blade 503.

[0035] After the flushing work is completed, the electric gate valve 504 is opened, and the third motor 502 drives the auger blade 503 to rotate to discharge the solid debris accumulated in the arc groove 501. At the same time, the inner wall of the shell 1 located above the arc groove 501 is fixedly connected with an L-shaped filter screen 505, and the L-shaped filter screen 505 and the inner wall of the shell 1 form a filter pool. The side wall of the shell 1 is fixedly installed with a second water pump 506, the water pumping end of the second water pump 506 is connected to the inside of the filter pool, and the water outlet end is connected to the inside of the water tank 7, which is used to extract the filtered water in the filter pool and transport it to the water tank 7 to achieve the recycling of water resources.

[0036] The knocking mechanism 6 includes a rotating rod 601 that is rotatably connected to the inner wall of the housing 1, and the rotating rod 601 passes through the inside of the second belt 401. The outer wall of the rotating rod 601 is fixedly connected to a plurality of connecting rods 602, and the end of the connecting rod 602 is fixedly connected to a knocking head 603, which is used to knock the inner wall of the second belt 401 located above the waste receiving trough 5. The side wall of the housing 1 is fixedly installed with a fourth motor 604 that is axially connected to one end of the rotating rod 601. The fourth motor 604 drives the rotating rod 601 to rotate, so that the knocking head 603 knocks the second belt 401, and knocks the water-dust mixed wastewater in the inclined trough 402 into the waste receiving trough 5 more thoroughly.

[0037] The inner wall of the outer shell 1 near the bottom is equipped with four symmetrically arranged limiting wheels 101 for supporting the ground, and the cross section of the bottom of the limiting wheels 101 is located on the same horizontal plane as the bottom of the lower end of the guide groove 3 to ensure the smooth operation of the equipment. The inner wall of the outer shell 1 located below the second belt 401 is fixedly connected with a waste receiving cover 9, and a horizontal plate 901 is fixedly provided on the side of the waste receiving cover 9 near the guide groove 3, and the end of the horizontal plate 901 is blocked with the bottom of the guide groove 3 to prevent debris from falling. The side wall of the waste receiving cover 9 located below the waste receiving groove 5 is provided with a cleaning port, and a door panel that can be opened and closed is installed on the cleaning port to facilitate cleaning of the inside of the waste receiving cover 9.

[0038] When the construction site road washing device of the present invention is actually used, it is usually installed on a lifting frame on a mobile vehicle, with one side of the waste receiving tank 5 facing the moving direction of the mobile vehicle. The specific operation steps are as follows: The lifting frame of the mobile trolley descends, so that the bottom of the shell 1 is close to the ground, and the lower end of the guide groove 3 is in contact with the road surface, and then the mobile trolley moves forward.

[0039] Start the first motor 216, and the first belt 201 runs in a circulation. When the fan-shaped nozzle 203 follows the first belt 201 and runs below it, the fan-shaped nozzle 203 is triggered to spray water obliquely toward the ground. As the first belt 201 continues to run, the fan-shaped nozzle 203 moves toward the direction of the guide trough 3, and the water sprayed by it impacts the water flow on the ground and the dust on the ground moves to the inclined material trough 402, and then the water and dust are mixed and enter the inclined material trough 402.

[0040] The second motor 406 is started, and the second belt 401 circulates. The inclined material trough 402 filled with water-dust mixed wastewater runs to one side of the waste receiving trough 5, with the port of the inclined material trough 402 facing downward. At the same time, the fourth motor 604 is started, and the knocking mechanism 6 knocks the inner wall of the second belt 401 above one side of the waste receiving trough 5 to knock the water-dust mixed wastewater into the waste receiving trough 5.

[0041] If stubborn soil is encountered on the ground, the mobile vehicle is reversed, and the lower end of the diversion trough 3 is used to remove the stubborn soil, while the fan-shaped nozzle 203 continues to do the flushing work.

[0042] Through the above specific implementation methods, the construction site road flushing equipment of the present invention can efficiently flush the construction site roads, and at the same time realize the collection and treatment of wastewater and debris, and has good practicality and environmental protection.

[0043] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed by the present invention shall still be covered by the claims of the present invention.
