Description

Technical Field

[0001] This invention relates to the field of road engineering technology, specifically to an asphalt pavement drainage channel processing device and processing method. Background Technology

[0002] Asphalt pavement refers to various types of pavement constructed by mixing road asphalt materials with mineral materials and then spreading and compacting them. The structural layers of asphalt pavement can consist of surface layer, base layer, subbase layer, and subbase layer. Asphalt binder improves the ability of paving aggregates to resist damage to the pavement from traffic and natural factors. Therefore, asphalt pavement is one of the most widely used high-grade pavements in road construction. Asphalt pavement exhibits sufficient stability under high temperature conditions, crack resistance under low temperature conditions, good water stability, long-lasting anti-aging properties, and skid resistance that is conducive to safety, making the pavement smooth, dust-free, impermeable, and durable.

[0003] Road surface drainage channels are facilities integrated into road engineering to remove rainwater and snowmelt, urban wastewater, groundwater, and lower the groundwater level. They are an important component of road engineering and also form part of drainage or flood control projects. Heavy rain runoff and snow cover can cause water accumulation on roads. This water, along with stagnant water, groundwater, and spring water, can soften, erode, and even damage the roadbed, leading to slope collapses, road frost heave, and other problems. The function of road drainage facilities is to quickly remove road surface runoff and various types of urban wastewater, prevent water accumulation, lower excessively high groundwater levels, and remove water that seeps into the road structure and roadbed. This ensures roadbed stability, extends the service life of the road surface, maintains normal traffic and safety for vehicles and pedestrians, and keeps roads clean and hygienic.

[0004] When asphalt pavements are exposed to moisture, they are subjected to repeated traffic loads and temperature fluctuations. On the one hand, moisture gradually penetrates the interface between asphalt and aggregates. On the other hand, due to the action of water dynamics, the asphalt film gradually peels off from the aggregate surface, leading to the loss of adhesion between aggregates and pavement damage. Therefore, drainage of asphalt pavements is particularly important. The common method for road drainage is to dig drainage ditches on both sides of the road to quickly drain water from the pavement.

[0005] Currently, existing technologies typically use excavating machinery to dig trenches of a certain width and depth on both sides of the asphalt pavement, leveling the sides and bottom of the trenches, and then laying U-shaped drainage channels in the leveled trenches. However, leveling the trenches requires manual shoveling, and the excavated soil falls into the trenches, which usually requires workers to shovel it out by hand, which is time-consuming, labor-intensive, and inefficient. Therefore, it does not meet the current needs. To address this, we propose an asphalt pavement drainage channel processing device and processing method. Summary of the Invention

[0010] As an optional embodiment of the asphalt pavement drainage groove processing device of the present invention, wherein: one end of the shovel is provided with a cutting edge, the upper side of the shovel is provided with an arc shape, a first support rod is installed on the side of the shovel, the number of the first support rods is set to several, and the end of the first support rod is connected to the lifting arm.

[0011] As an optional embodiment of the asphalt pavement drainage groove processing device of the present invention, the conveying assembly further includes a support frame, a second bearing, a insert shaft, a gear, and a chain. The number of support frames is set to several. The second bearing is installed inside the support frame. The insert shaft is inserted into the second bearing. The gear is sleeved on the outside of one side of the insert shaft and is located in the inner cavity of one of the support frames. The chain meshes with the outside of the gear. The insert shaft is in contact with the inner ring of the second bearing. The support frame is in contact with the outer ring of the second bearing. A second support rod is installed on the outside of each support frame. The second support rod is connected to the lifting arm.

[0012] As an optional embodiment of the asphalt pavement drainage groove processing device of the present invention, wherein: a second motor is installed on the outside of one of the support frames, and the output shaft of the second motor is connected to one of the insert shafts for transmission.

[0013] As an alternative to the asphalt pavement drainage groove processing device of the present invention, one of the conveying components is inclined and the other conveying component is horizontal.

[0014] As an optional embodiment of the asphalt pavement drainage groove processing device of the present invention, wherein: a first fixing block is installed on the side of the trolley, a second fixing block is installed on the side of the machine body, a fixing bolt is inserted into the side of the second fixing block, the fixing bolt passes through the first fixing block, and a fixing nut is screwed onto the fixing bolt.

[0015] This invention also proposes a method for processing drainage channels in asphalt pavements, comprising the following specific steps:

[0016] S1. Drive the machine body so that the cutting blade and the shovel blade level the excavated drainage ditch: lower the cutting blade and the shovel blade into the excavated drainage ditch, and drive them forward. The cutting blade cuts and levels the uneven soil on both sides of the drainage ditch, while the shovel blade levels the bottom of the drainage ditch.

[0017] S2. The removed soil is sent out of the drainage ditch through the transmission assembly: the removed soil accumulates on the upper side of the shovel, and the soil at the front pushes the soil at the rear onto the inclined conveyor belt, and the soil is conveyed upward to the horizontal conveyor belt.

[0018] S3. Collect the removed soil: The cart moves with the machine body, and the soil falls into the cart through the horizontal conveyor belt.

[0019] As an alternative to the asphalt pavement drainage ditch processing method of the present invention, after performing step S3, the trolley is removed from the machine body to facilitate the centralized treatment of the soil in the trolley. The empty trolley is then installed on the machine body to continue working. Then, "U"-shaped slabs are laid in the flat drainage ditch, and then asphalt is laid and compacted on the road surface.

[0020] The present invention has the following beneficial effects:

[0021] 1. The asphalt pavement drainage ditch processing device and method, through the setting of the lifting arm, allows the mounting shell to lower the cutting blade into the excavated trench, and the lifting arm also lowers the shovel blade to the bottom of the trench. As the cutting blade rotates, it is driven forward by the machine body, allowing the cutting blade to cut and level the uneven soil on the trench sidewalls. Simultaneously, the machine body drives the shovel blade to move along the bottom of the trench, leveling the bottom. The removed soil accumulates on the upper side of the shovel blade and then falls onto the conveyor belt of the inclined conveyor assembly. The driving roller drives the driven roller to rotate, causing the conveyor belt to rotate. The toothed design prevents the conveyor from being... The soil carried on the conveyor slides down, while the soil on top is transported upwards to a horizontally set conveyor assembly. Finally, it falls from the end of the horizontally set conveyor assembly into a trolley, thus leveling the trench. This improves work efficiency and solves the problem that existing technologies typically use excavating machinery to dig trenches of a certain width and depth on both sides of the asphalt road surface, level the sides and bottom of the trenches, and then lay "U"-shaped drainage channels in the leveled trenches. However, when leveling the trenches, manual shoveling is required, and the soil removed falls into the trenches, which usually requires workers to shovel it out by hand, which is time-consuming, labor-intensive, and inefficient.

[0022] 2. The asphalt pavement drainage ditch processing device and processing method uses a second motor to drive the active roller to rotate, which in turn drives the gear on the active roller to rotate. Through the meshing transmission of the chain and gear, the driven roller is driven to rotate, which facilitates the rotation of the conveyor belt, thereby facilitating the transportation of the removed soil and further improving the efficiency of leveling the ditch.

[0023] 3. The asphalt pavement drainage channel processing device and processing method, by setting the upper surface of the shovel blade to a concave arc shape with the rear side curving upward, makes it easy for the soil on the shovel blade to accumulate backward and upward. The groove set at the rear end of the shovel blade makes the lower end of the conveyor belt below the accumulated soil, so that when the soil on the shovel blade is squeezed backward, it is easy to fall onto the conveyor belt.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example 1

[0035] This embodiment aims to address the problem of existing technologies that typically use excavating machinery to dig trenches of a certain width and depth on both sides of asphalt pavement, leveling the sides and bottom of the trenches, and then laying U-shaped drainage channels in the leveled trenches. However, the trench leveling process requires manual shoveling, and the excavated soil falls into the trench, which usually needs to be shoveled out by hand by workers. This is time-consuming, labor-intensive, and inefficient. Please refer to [link to relevant documentation]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 An asphalt pavement drainage groove processing device and processing method are disclosed, including a machine body 110, which is configured as a drive vehicle and is equipped with a driver's cab, so that the driver can easily operate the device from the driver's cab.

[0036] A lifting arm 120 is slidably arranged on the inner side of the machine body 110. There are two lifting arms 120, which are symmetrically arranged on the left and right sides in front of the machine body 110. A telescopic component 121 is installed on the inner side of the machine body 110. The telescopic component 121 is a hydraulic cylinder or a telescopic air cylinder. There are two telescopic components 121. The two lifting arms 120 are respectively connected to the telescopic ends of the two telescopic components 121. Two sliding grooves are opened on the outer side of the machine body 110 to facilitate the lifting arm 120 to move up and down in them.

[0037] Each end of the lifting arm 120 is equipped with a mounting shell 130, and a cutting blade 140 is rotatably mounted inside each mounting shell 130. Each mounting shell 130 is semi-circular, and a first bearing 141 is installed on the inner side of each mounting shell 130. The number of first bearings 141 is set to two. A first motor 142 is installed on the outer side of the mounting shell 130. The output shaft of the first motor 142 passes through the inner ring of the mounting shell 130 and the first bearing 141. The output shaft of the first motor 142 is interference-fitted into the center of the side of the cutting blade 140. The cutting edge of the cutting blade 140 is evenly provided with serrations to facilitate cutting the soil. The output shaft of the first motor 142 is in contact with the inner ring of the first bearing 141, and the mounting shell 130 is in contact with the outer ring of the first bearing 141.

[0038] A scraper 150 is arranged between the cutting blades 140. A conveying assembly 160 is arranged on one side of the scraper 150. There are two conveying assemblies 160, one of which is inclined and the other is horizontal. The conveying assembly 160 includes a driving roller 170, a driven roller 180 and a conveyor belt 190. The conveyor belt 190 is sleeved between the driving roller 170 and the driven roller 180. The inclined conveyor belt 190 has teeth 210 evenly installed on its outer side. The number of teeth 210 is set to several.

[0039] A trolley 220 is provided on the side of the machine body 110. A handle is installed on the outside of the trolley 220 to facilitate pushing the trolley 220. The trolley 220 is located below the horizontally arranged conveyor belt 190. A first fixing block 221 is installed on the side fixing part of the trolley 220. A second fixing block 222 is fixedly installed on the side of the machine body 110. A fixing bolt 223 is inserted on the upper side of the second fixing block 222. The fixing bolt 223 passes through the second fixing block 222 and the first fixing block 221. A fixing nut 224 is screwed onto the fixing bolt 223.

[0040] In this embodiment: The lifting arm 120 lowers the mounting housing 130 and the cutting blade 140 into the excavated trench, while the lifting arm 120 lowers the shovel 150 to the bottom of the trench. The cutting blade 140 rotates while being driven forward by the machine body 110, allowing it to cut and level the uneven soil on the trench sidewalls. Simultaneously, the machine body 110 drives the shovel 150 forward along the bottom of the trench, leveling the bottom. The removed soil accumulates on the shovel 150 and then falls onto the conveyor belt 190 of the inclined conveyor assembly 160. The driving roller 170 drives the driven roller 180 to rotate, causing the conveyor belt 190 to rotate. The toothed design 210 prevents soil on the conveyor belt 190 from sliding down, instead transporting the soil upwards to the horizontally positioned conveyor assembly 160. Finally, the soil is placed into the trolley 220 from the end of the horizontally positioned conveyor assembly 160, thus leveling the trench and improving work efficiency. This addresses the problem of existing technologies that typically use excavating machinery to dig trenches of a certain width and depth on both sides of the asphalt road surface, leveling the sides and bottom of the trench, and then laying "U"-shaped drainage channels in the leveled trench. However, the trench leveling process requires manual shoveling, and the excavated soil falls into the trench, which usually requires workers to shovel it out by hand, resulting in a time-consuming, labor-intensive, and inefficient process.

[0041] Example 2

[0042] This embodiment aims to address the problem of the conveyor belt 190 being difficult to rotate. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 The conveying assembly 160 also includes a support frame 191, a second bearing 192, a shaft 193, a gear 194, and a chain 195. The number of support frames 191 is set to two. The second bearing 192 is installed inside the support frame 191. The shaft 193 is inserted into the second bearing 192. The gear 194 is sleeved on the outside of the left side of the shaft 193. The shaft 193 is connected to the left and right ends of the driving roller 170 and the driven roller 180, respectively.

[0043] The conveyor belt 190 is sleeved on the outside of the drive roller 170 and the driven roller 180. The gear 194 is set in the inner cavity of the left support frame 191. The chain 195 meshes with the outside of the gear 194. The insert shaft 193 is in contact with the inner ring of the second bearing 192. The support frame 191 is in contact with the outer ring of the second bearing 192. The second support rods 196 are installed on the outside of the support frame 191. The second support rods 196 are connected to the lifting arm 120. The second motor 197 is installed on the outside of the support frame 191 where the gear 194 is set. The output shaft of the second motor 197 is connected to the insert shaft 193 on the drive roller 170, so that the output shaft of the second motor 197 is connected to the drive roller 170 for transmission.

[0044] In this embodiment: the second motor 197 drives the active roller 170 to rotate, causing the gear 194 on the active roller 170 to rotate. Through the meshing transmission between the chain 195 and the gear 194, the driven roller 180 is driven to rotate, which facilitates the rotation of the conveyor belt 190, thereby facilitating the transportation of the removed soil and further improving the efficiency of leveling the trench.

[0045] Example 3

[0046] This embodiment aims to address the problem of soil on the shovel 150 not easily falling onto the conveyor belt 190. This embodiment is an improvement upon Embodiment 1. For details, please refer to [link to Embodiment 1]. Figure 1 , Figure 2 , Figure 3 and Figure 5 The front end of the shovel 150 is provided with a cutting edge to facilitate leveling the soil. The upper side of the shovel 150 is set with a concave arc shape, and the rear end of the shovel 150 is higher than the front end. A first support rod 151 is installed on the left and right sides of the shovel 150, and the number of first support rods 151 is set to two. The upper end of the first support rod 151 is connected to the lifting arm 120. The rear end of the shovel 150 is provided with a groove, and the driven roller 180 in the inclined transmission assembly 160 is set in the groove at the rear end of the shovel 150, so that the conveyor belt 190 is in the groove.

[0047] In this embodiment: by setting the upper surface of the shovel 150 to a concave arc shape with the rear side curving upward, it is easy for the soil on the shovel 150 to accumulate backward and upward. Through the groove set at the rear end of the shovel 150, the lower end of the conveyor belt 190 is located below the accumulated soil, so that when the soil on the shovel 150 is squeezed backward, it is easy to fall onto the conveyor belt 190.
