Description

Technical Field

[0001] This invention relates to the field of highway maintenance technology, and specifically to a pothole treatment device for highway maintenance. Background Technology

[0002] During daily use, roads are susceptible to cracks and potholes due to factors such as climate, environment, and vehicle operation. This is especially frequent in areas with heavy rainfall and snowfall. Current pothole repair methods follow the principle of "square patching for round holes, straight patching for slanted holes, and deep patching for shallow holes," involving chiseling the cracks into rectangular potholes, cleaning out dust and water, filling with adhesive and cold patching material, and finally compacting the surface. However, considering that roads are more prone to potholes in areas with heavy rainfall and snowfall, and that pothole filling should be kept as clean and dry as possible, current technology only uses a blower to remove water and dust from the potholes. While existing technologies offer limited cleaning and drying capabilities, in southern regions during the rainy season or in special circumstances such as sudden rain during repairs, large amounts of water can accumulate on the road surface for extended periods. Workers relying solely on blowers cannot effectively collect and manage the water from potholes. The water will still flow back into the pothole area through its edges. Excessive water accumulation during pothole filling can negatively impact the adhesion between the cold patch material and the existing road surface, leading to weak adhesion and making the filled section more prone to new road cracks, thus affecting the lifespan of the repaired road. Therefore, it is necessary to design a pothole treatment device for highway maintenance to address the shortcomings of existing technologies. Summary of the Invention

[0014] Compared with the prior art, the present invention has the following advantages: 1. This invention defines the repair area by using a rectangular frame composed of a first right-angle frame and a second right-angle frame. By keeping the first and second right-angle frames close to the road surface, the water flow inside and outside the rectangular frame is blocked, preventing water from flowing back into the rectangular frame. This allows workers to more effectively clean the water and road surface inside the rectangular frame, improving the work efficiency of road maintenance in harsh environments.

[0015] 2. This invention uses a sensor to detect the pressure of the first elastic element and determines the depth to which the cutting saw cuts the road surface, thus avoiding excessive or insufficient cutting when it is inconvenient to observe, which would affect the effectiveness of road maintenance.

[0016] 3. This invention uses a sliding plate and a vibratory tamper to chisel the road surface at the four corners of a rectangular frame, filling the gaps where the cutting saw cannot cut the right angles of the rectangular frame. At the same time, the combination of the extrusion plate and the tamping hammer achieves the dual-purpose effect of the vibratory tamper, improving the applicability of this device.

[0017] 4. By adjusting the size of the air vent on the vent housing, this invention allows the vent housing to not only clean the side walls of the road surface within the rectangular frame, but also maintain the ventilation area of ​​the air vent on the vent housing, thereby maintaining the efficiency of the vacuum cleaner and dryer and achieving a more thorough cleaning effect.

[0018] 5. This invention detects the amount of accumulated cold patch material by using a spreading plate. When the amount is large, the feeding speed of the square guide tube is reduced, and when the amount is small, the feeding speed of the square guide tube is increased to maintain the amount of accumulated cold patch material during the spreading process and avoid excessive waste of cold patch material during spreading.

[0022] Example 1: A pothole treatment device for highway maintenance, such as Figures 1-5As shown, the system includes a repair vehicle 1. A carriage 2 and a control panel (not shown in the diagram) are fixedly connected to the left side of the repair vehicle 1. The control panel is equipped with a matching remote control device. Two mirror-image rain covers 3 are rotatably connected to the upper side of the carriage 2. Two mirror-image first electric slide rails 4, electrically connected to the remote control device, are fixedly connected inside the carriage 2. Two mirror-image second electric slide rails 5, electrically connected to the remote control device, are also fixedly connected inside the carriage 2. Two mirror-image first hydraulic push rods 6 are fixedly connected inside the carriage 2. Second hydraulic push rods 7 are fixedly connected to the electric sliders of the second electric slide rails 5. A first right-angle bracket 8 is fixedly connected to the telescopic end of the front first hydraulic push rod 6, and a second right-angle bracket 9 is fixedly connected to the telescopic end of the front second hydraulic push rod 7. First electric push rods 10, electrically connected to the remote control device, are fixedly connected to the telescopic ends of the rear first hydraulic push rod 6 and the rear second hydraulic push rod 7. The left side first electric... The telescopic end of the push rod 10 is fixedly connected to the second right-angle frame 9, and the telescopic end of the first electric push rod 10 on the right side is fixedly connected to the first right-angle frame 8. The first right-angle frame 8 is slidably connected to the adjacent second right-angle frame 9. The two first right-angle frames 8 and the two second right-angle frames 9 connected to each other form a rectangular frame. The two first right-angle frames 8 are not adjacent, and the two second right-angle frames 9 are not adjacent. The bottom surfaces of the two first right-angle frames 8 and the two second right-angle frames 9 are on the same horizontal plane and are all equipped with sealing rubber pads. When the rectangular frame formed by the two first right-angle frames 8 and the two second right-angle frames 9 is close to the road surface 11, the rectangular frame and the road surface 11 maintain a sealed fit to block the water flow inside and outside the rectangular frame. The mirror-distributed first electric slide rails 4 are jointly equipped with a cutting mechanism for cutting the road surface 11 and a compaction mechanism for cutting, breaking and compacting the road surface 11. Both the cutting mechanism and the compaction mechanism are electrically connected to the remote control device.

[0023] like Figure 3 , Figure 4 and Figure 6As shown, the cutting mechanism includes a third electric slide rail 101 electrically connected to a remote control device. Four electric sliders are slidably connected to the first electric slide rail 4. The third electric slide rail 101 is simultaneously fixed to the leftmost electric slider of two mirror-image first electric slide rails 4. A first support block 102 is slidably connected to the third electric slide rail 101 via the electric sliders. A third hydraulic push rod 103 electrically connected to the remote control device is fixed to the first support block 102. The telescopic end of the third hydraulic push rod 103 extends or retracts downwards. A rotating block 104 electrically connected to the remote control device is rotatably connected to the telescopic end of the third hydraulic push rod 103. The rotating block 104 is used to drive the lower part to rotate 90 degrees. Two mirror-image first electric slide rails 104 are fixed to the rotating block 104. A telescopic rod 105 is mirrored on two other telescopic rods 105. Both telescopic ends of the telescopic rods 105 are equipped with a cutting saw 106 that is electrically connected to a remote control device. A first elastic element 107 is fixedly connected between the cutting saw 106 and the rotating block 104. The first elastic element 107 is a spring. When the cutting saw 106 contacts the road surface 11, the first elastic element 107 is compressed by the squeezing force of the ground on the cutting saw 106. A sensor 108 is fixedly connected to the rotating block 104 to detect the elastic force of the first elastic element 107. By detecting the elastic force of the first elastic element 107, it can be determined whether the cutting saw 106 is cutting the road surface 11 or snow and thin ice, so as to accurately control the cutting depth of the cutting saw 106. The sensor 108 is electrically connected to the remote control device.

[0024] like Figure 5 , Figure 7 and Figure 8As shown, the compaction mechanism includes two sets of mirror-image and evenly distributed fourth electric slide rails 201. Each set contains two fourth electric slide rails 201 electrically connected to the remote control device. The two mirror-image fourth electric slide rails 201 on the left are fixed to the first right-angle bracket 8 and the second right-angle bracket 9 on the left, respectively. The two mirror-image fourth electric slide rails 201 on the right are fixed to the first right-angle bracket 8 and the second right-angle bracket 9 on the right, respectively. The upper sides of all four fourth electric slide rails 201 are slidably connected to a sliding block via an electric slider. The movable support 202 and the sliding supports 202 on both the front and rear sides are symmetrically distributed. The sliding supports 202 are slidably connected to the sliding plates 203. A right-angle chisel is fixed to the lower side of the sliding plate 203. The chisel tip faces the road surface 11, and the thickness of the right-angle chisel on the sliding plate 203 is the same as the thickness of the saw blade on the cutting saw 106. When the sliding support 202 slides along the adjacent fourth electric slide rail 201 to the side close to the rectangular frame, the right-angle sides of the first right-angle bracket 8 and the second right-angle bracket 9 are respectively connected to the adjacent sliding plates 203. The four right-angle chisels are matched, and their striking positions are exactly at the four right angles of the rectangular frame. A second elastic element 204 is fixedly connected between the sliding plate 203 and the adjacent sliding bracket 202. The second elastic element 204 is set as a tension spring. The third electric slider from left to right on the two mirrored first electric slide rails 4 is fixedly connected to a fifth electric slide rail 205. The fifth electric slide rail 205 is electrically connected to the remote control device. The fifth electric slide rail 205 is slidably connected to a second support block 206 through the electric slider. The second support block 206 is fixedly connected to... The fourth hydraulic push rod 207, with its telescopic end facing the road surface 11, has a vibratory tamper 208 that is electrically connected to the telescopic end of the fourth hydraulic push rod 207. The vibratory tamper 208 is equipped with tamping hammers 209 that cooperate with four sliding plates 203. The vibratory tamper 208 strikes the four sliding plates 203 in sequence through the tamping hammers 209, causing the right-angle chisels on the four sliding plates 203 to chisel the road surface 11. The vibratory tamper 208 is equipped with a crushing component for crushing the road surface 11 within the rectangular frame. The crushing component is electrically connected to the remote control device.

[0025] like Figure 3 , Figure 8 and Figure 9As shown, the crushing assembly includes two mirror-distributed second electric push rods 210, both of which are electrically connected to a remote control device. Both second electric push rods 210 are fixed to a vibratory tamper 208. The telescopic ends of the second electric push rods 210 face downwards and are fixedly connected to wedge blocks 211. The upper side of the wedge blocks 211 has an inclined surface. The lower part of the vibratory tamper 208 is fixedly connected to two mirror-distributed elastic telescopic plates 212. The elastic telescopic plates 212 are slidably connected via support rods to compression plates 213 that cooperate with the inclined surfaces of adjacent wedge blocks 211. The compression plates 213 are folded plates with a horizontal lower plate... The lower side is fixed with breaking spikes. Both extrusion plates 213 are matched with the tamping hammer 209. The combination of the three changes the vibratory tamping 208 into a breaker hammer to break the road surface within the rectangular frame. A third elastic element 214 is fixed between the elastic telescopic plate 212 and the adjacent extrusion plate 213. The third elastic element 214 is set as a tension spring. The elastic force of the elastic telescopic plate 212 is greater than the elastic force of the third elastic element 214, so that when the extrusion plate 213 moves downward with the adjacent wedge block 211, it first moves downward and then laterally. When the extrusion plate 213 is squeezed upward by the adjacent wedge block 211, it first moves laterally and then upward.

[0026] The workers first drove the repair vehicle 1 to the section of road to be repaired and parked it above the pothole 11. More precisely, they parked the vehicle body 2 above the pothole 11, trying to position the pothole 11 as close as possible to the first right-angle frame 8 on the left side of the vehicle body 2. After the repair vehicle 1 was brought to a stable stop, the workers got out of the vehicle and began repairing the pothole 11. The specific operating steps are as follows: First, the operator uses a remote control to move the telescopic ends of the two first hydraulic push rods 6 and the two second hydraulic push rods 7 downwards. These telescopic ends push the two first right-angle frames 8 and the two second right-angle frames 9 downwards to a position close to the pothole 11 in the road surface. Then, the operator uses the remote control to control the second hydraulic push rods 7 to slide on adjacent second electric slide rails 5, thereby controlling the left and right length of the rectangular frame formed by the two first right-angle frames 8 and the two second right-angle frames 9. This is achieved by controlling the extension or retraction distance of the first electric push rod 10. This controls the front and rear width of the rectangular frame, which is used to delineate the specific repair area, i.e., to determine the size and position of the rectangular frame (the area inside the rectangular frame is the repair area). After the staff determines the specific repair area, they control the two first hydraulic push rods 6 and the two second hydraulic push rods 7 to move down simultaneously through the remote control device until the two first right-angle brackets 8 and the two second right-angle brackets 9 are close to the road surface 11. At this time, the water on the road surface 11 cannot flow from the outside of the rectangular frame to the inside of the rectangular frame. Also, because the rain cover 3 on the upper side of the carriage 2 is in a closed state, if it suddenly rains while repairing the pothole, the rainwater will not enter the rectangular frame from the upper side.

[0027] After the two first right-angle frames 8 and the two second right-angle frames 9 are close to the ground surface 11, the worker controls the electric slider on the first electric slide rail 4 to move, which drives the third electric slide rail 101 to slide along the first electric slide rail 4. The third electric slide rail 101 drives the cutting saw 106 to move together through the first support block 102, the third hydraulic push rod 103, the rotating block 104, and the first telescopic rod 105, so that the cutting saw 106 moves to above the first right-angle frame 8 on the left. Then, the worker controls the third hydraulic push rod 103 to push the part fixed at its telescopic end through the remote control device. The component drives the cutting saw 106 to move downwards, so that the cutting saw 106 moves down to the upper side of the road surface 11. The electric slider on the third electric slide rail 101 is controlled by the remote control device to drive the first support block 102 and its components to slide back and forth, so as to adjust the front and back position of the cutting saw 106. The electric slider on the first electric slide rail 4 drives the third electric slide rail 101 and its components to slide left and right, so as to adjust the left and right position of the cutting saw 106. Then, by using the above operation methods in combination, the operator adjusts the cutting saw 106 to a position close to the edge of the rectangular frame.

[0028] After the cutting saw 106 is adjusted to be flush with the edge of the rectangular frame, the operator starts the cutting saw 106 via a remote control. Once the cutting saw 106 is working, the operator controls the extension end of the third hydraulic push rod 103 to move adjacent components and the cutting saw 106 downwards until it contacts the road surface 11. The cutting saw 106 experiences pressure from the road surface 11, thus compressing the first elastic element 107 and the first extension rod 105. The first elastic element 107 stores elastic force during compression. This is especially important when there is snow or thin ice above the road surface 11. When the cutting saw 106 cuts the snow and thin ice, the first elastic element 107 stores less elastic force than when the cutting saw 106 cuts the road surface 11. The sensor 108 determines whether the cutting saw 106 is cutting the road surface 11 or the snow and thin ice by detecting the elastic force stored in the first elastic element 107. When the cutting saw 106 cuts the road surface 11, the workers start to calculate the cutting depth to accurately grasp the specific cutting depth of the cutting saw 106 and prevent the cutting from being too deep or too shallow due to excessive snow on the road surface 11, which would affect the quality of the pothole repair.

[0029] When the operator controls the cutting saw 106 to cut the road surface 11, when cutting in the left and right direction, the first electric slide rail 4 drives the third electric slide rail 101 and the cutting saw 106 to move horizontally left and right through its electric slider. When cutting in the front and back direction, the operator first controls the rotating block 104 to rotate the cutting saw 106 90 degrees through the remote control device, and then controls the electric slider on the third electric slide rail 101 to move the cutting saw 106 back and forth. Finally, in addition to cutting the edge of the rectangular frame, the operator uses the same working principle to cut the road surface 11 within the rectangular frame into a grid pattern to facilitate subsequent crushing work.

[0030] After the workers have finished cutting the road surface 11 within the rectangular frame, because the cut edge of the cutting saw 106 cannot extend beyond the rectangular frame and form new road cracks, the four right angles of the road surface 11 within the rectangular frame are still connected to the road surface 11 outside the rectangular frame and are not directly cut off by the cutting saw 106. At this time, the workers use the remote control to reverse the operation to reset the cutting saw 106 and move it to the leftmost side of the first electric slide rail 4. At this time, the cutting saw 106 is located on the upper left side of the rectangular frame and does not affect the operation of other devices. After the workers reset the cutting saw 106, they use the remote control to control the electric sliders on the four fourth electric slide rails 201 to drive the adjacent sliding brackets 202 to slide. When the four sliding brackets 202 slide to the adjacent first right angle bracket 8 and the adjacent second right angle bracket 9 respectively, the right angle chisels on the four sliding plates 203 are exactly located at the four right angles of the rectangular frame. After the four right angle chisels are in place, the workers use the remote control to control the vibratory tamping machine 208 to work.

[0031] In the initial state, the second electric push rod 210 is in a retracted state. At this time, the two second electric push rods 210 drive the lower wedge block 211 to squeeze the adjacent extrusion plate 213. The two extrusion plates 213 are located on the front and rear sides above the hammer 209. The third elastic element 214 is stretched and the elastic telescopic plate 212 is compressed. That is, at this time, the two extrusion plates 213 are not in cooperation with the hammer 209, and the bottom surface of the hammer 209 is flat.

[0032] The operator uses a remote control to control the electric slider on the first electric slide rail 4, which drives the fifth electric slide rail 205 to slide left and right, thus controlling the left and right position of the vibratory tamper 208. By controlling the electric slider on the fifth electric slide rail 205, the operator drives the second support block 206 to slide back and forth. The second support block 206, by moving its components, moves the vibratory tamper 208, thus controlling its front and back position. By controlling the extension or retraction of the fourth hydraulic push rod 207, the operator controls the up and down movement of the vibratory tamper 208 and the hammer 209. Using the above control method, the operator moves the vibratory tamper 208 sequentially to the upper side of the four sliding plates 203, causing the vibratory tamper 208 to drive the hammer 209 to impact the four sliding plates 203 in turn. Taking the hammer 209 impacting the left front sliding plate 203 as an example, the specific process is as follows: The operator places the hammer 209 against the sliding plate 203 on the left front. Then, the operator controls the vibratory rammer 208 to work via a remote control. The vibratory rammer 208 causes the hammer 209 to continuously impact the adjacent sliding plate 203. At the same time, the operator controls the fourth hydraulic push rod 207 to move the hammer 209 downward synchronously, which in turn moves the adjacent right-angle chisel downward. The chisel vertically strikes the road surface 11 below along the right angle of the rectangular frame until the right-angle chisel of the sliding plate 203 reaches the same cutting depth as the cutting saw 106. The operator then controls the vibratory rammer 208 to stop working via the remote control and repeats the above process to impact other sliding plates 203. When the vibratory rammer 208 leaves the current position of the sliding plate 203, the two disengage, and the sliding plate 203 resets under the elastic force of the adjacent second elastic element 204.

[0033] Workers controlled the vibratory tamper 208 to chisel open the four right-angled sides of the rectangular frame, completely separating the road surface 11 inside and outside the rectangular frame. Then, workers used a remote control to control the four fourth electric slide rails 201 to reset the adjacent sliding supports 202, while simultaneously controlling the extension of the two second electric push rods 210. The extension ends of the second electric push rods 210 moved the wedge blocks 211 downwards. Because the elastic force of the elastic telescopic plate 212 was greater than that of the third elastic element 214, the elastic telescopic plate 212 reset first. The elastic telescopic plate 212 pushed the extrusion plate 213 and its components downwards along with the wedge blocks 211. When the elastic telescopic plate 212 was fully reset, the extrusion plate 213 stopped moving downwards. At this point, the part of the extrusion plate 213 carrying the broken spikes... On both sides of the bottom of the tamping hammer 209, when the telescopic end of the second electric push rod 210 drives the wedge block 211 to continue to move downward, the third elastic element 214 gradually resets and pulls the adjacent extrusion plate 213 to move closer to the tamping hammer 209. When the telescopic end of the second electric push rod 210 extends to its limit position, the part of the two extrusion plates 213 carrying the breaking spikes moves to the right below the tamping hammer 209. At this time, the vibratory tamping hammer 208 becomes a vibratory hammer carrying breaking spikes. The workers then control the vibratory tamping hammer 208 to move within the rectangular frame according to the above method to fully break the road surface 11 within the rectangular frame. At this time, the road surface 11 within the rectangular frame is a grid structure that is not connected to the outside, and the road surface 11 within the rectangular frame is more easily broken by the vibratory tamping hammer 208.

[0034] After the workers completely break up the road surface 11 within the rectangular frame, they control the vibratory tamper 208 to move upward and reset using the aforementioned operation. Simultaneously, they control the two second electric push rods 210 to drive the two compression plates 213 upward and reset together via the wedge blocks 211. The two compression plates 213 first compress the adjacent third elastic element 214 to reset laterally, causing the two compression plates 213 to disengage from the hammer 209. When the third elastic element 214 is compressed to its limit position, the compression plates 213 then compress the adjacent elastic telescopic plate 212 to begin retracting upward and resetting. After the vibratory tamper 208 and its components are completely reset, the vibratory tamper 208 begins to retract and reset within the rectangular frame. The broken road surface 11 was cleaned and the subsequent pothole filling operation was carried out. After the pothole filling was completed, the workers started the vibratory tamper 208 to compact the road surface 11 inside the rectangular frame in the order of outside to inside. Because the rectangular frame limits the cold patch material filling the road surface 11, the cold patch material inside the rectangular frame will not be squeezed to the outside of the rectangular frame during the compaction process. After the compaction is completed, the workers control the first hydraulic push rod 6, the second hydraulic push rod 7 and the first electric push rod 10 to reset. At this time, the two first right-angle frames 8 and the two second right-angle frames 9 are separated from the road surface 11. Then the workers drive the maintenance vehicle 1 back.

[0035] Example 2: Based on the reference in Example 1, such as Figure 3, Figure 4 , Figure 10 and Figure 11 As shown, it also includes a cleaning mechanism disposed on the first electric slide rail 4. The cleaning mechanism is electrically connected to the remote control device and is used to clean the broken road surface 11 within the rectangular frame. The cleaning mechanism includes a sixth electric slide rail 301 electrically connected to the remote control device. The sixth electric slide rail 301 is fixed to the second electric slider from left to right of the two first electric slide rails 4. The sixth electric slide rail 301 is slidably connected to a third support block 302 through the electric slider. The third support block 302 is fixed to a fifth hydraulic push rod 303 with its telescopic end pointing downward. The lower side of the telescopic end of the fifth hydraulic push rod 303 is fixed to a first fixing plate 304. The left side of the first fixing plate 304 is fixed to two mirror-distributed third electric push rods 305 electrically connected to the remote control device. The right side of the first fixing plate 304 is fixed to two mirror-distributed fourth electric push rods 306 electrically connected to the remote control device. The lower sides of the telescopic ends of the two third electric push rods 305 are rotatably connected to a device electrically connected to the remote control device. An electric rotating shaft 307 is connected to the rotating part of the electric rotating shaft 307, and a digging head 308 is fixedly connected to it. The digging head 308 is shovel-shaped and has an inclined surface on its lower side for pressing the bottom surface of the road surface 11. The telescopic ends of the two fourth electric push rods 306 are jointly fixedly connected to a second fixing plate 309. A circular connector 310 for communicating with a vacuum cleaner and a dryer is fixedly connected to the middle of the second fixing plate 309. Both the vacuum cleaner and the dryer are electrically connected to a remote control device. The bottom of the circular connector 310... A ventilation shell 311 is fixedly connected to it, and the ventilation shell 311 has several ventilation ports. The ventilation shell 311 has five ventilation ports, which face the front, back, left, right and down directions respectively. That is, the vacuum cleaner sucks up the dust and stones in the rectangular frame through the ventilation shell 311, and the dryer introduces dry hot air into the rectangular frame through the ventilation ports of the ventilation shell 311. The second fixed plate 309 is fixedly connected to an adjustment component that automatically adjusts the position and orientation of the ventilation ports of the ventilation shell 311.

[0036] like Figures 10-13As shown, the adjustment assembly includes two first baffles 312 arranged in a left-right mirror image. A bracket is provided on the lower side of the second fixed plate 309. Both first baffles 312 are slidably connected to the bracket of the second fixed plate 309. Two second baffles 313 arranged in a front-back mirror image are slidably connected to the second fixed plate 309 through the lower bracket. Both the first baffles 312 and the second baffles 313 have inclined surfaces. The right side of the first right-angle bracket 8 and the second right-angle bracket 9 on the left side mates with the inclined surface of the first baffle 312 on the left side. The left side of the first right-angle bracket 8 and the second right-angle bracket 9 on the right side mates with the inclined surface of the first baffle 312 on the right side. That is, the two first baffles 312 respectively mate with the left and right sides of the rectangular frame. Similarly, the second baffles 313 pass through their inclined surfaces. The first baffle 312 and the second fixed plate 309 are fixedly connected with a reset elastic element, and the second baffle 313 and the second fixed plate 309 are also fixedly connected with a reset elastic element. All four reset elastic elements are reset springs. The two first baffles 312 are respectively connected to the two vents on the left and right sides of the vent housing 311, and the two second baffles 313 are respectively connected to the two vents on the front and rear sides of the vent housing 311. The vent housing 311 is rotatably connected to two first windproof cloth rolls 314 that are mirror-distributed to the left and right. The first windproof cloth roll 314 consists of a rotating shaft and windproof cloth wound on it. The ends of the windproof cloth on the first windproof cloth roll 314 are slidably connected to the vent housing 311 to block the vents on the lower side of the vent housing 311 in the left and right horizontal directions, so as to ensure ventilation. The gas flow area of ​​the shell 311 remains relatively stable, ensuring stable working efficiency of the vacuum cleaner and dryer. Return torsion springs are fixedly connected between the rotating shafts of the two first windbreak cloth rolls 314 and the vent shell 311. Two mirror-distributed first guide posts 315 are fixedly connected to the left and right vents of the vent shell 311. A first steel wire 316 is fixedly connected between the end of the windbreak cloth on the left first windbreak cloth roll 314 and the right first baffle 312. The first steel wire 316 passes under the right first guide post 315. Similarly, a first steel wire 316 passing under the left first guide post 315 is fixedly connected between the end of the windbreak cloth on the right first windbreak cloth roll 314 and the left first baffle 312. Two mirror-distributed fixing brackets 317 are fixedly connected to the lower side of the vent shell 311. Two second windproof cloth rolls 318, arranged in a mirror-like pattern, are rotatably connected to a fixed frame 317. Each second windproof cloth roll 318 consists of a rotating shaft and windproof cloth wound around it. The ends of the windproof cloth on the second windproof cloth roll 318 are slidably connected to the fixed frame 317, used to block the air vents on the lower side of the vent housing 311 in the front and rear horizontal directions, ensuring that the gas flow area of ​​the vent housing 311 remains relatively stable, and ensuring the stable working efficiency of the vacuum cleaner and dryer. A return torsion spring is fixedly connected between the rotating shaft of the second windproof cloth roll 318 and the adjacent fixed frame 317. Two second guide posts 319, arranged in a mirror-like pattern, are fixedly connected between the two fixed frames 317. A second steel wire 320 is fixedly connected between the ends of the windproof cloth on the second windproof cloth roll 318 and the second baffle 313 away from itself.The second steel wire 320 passes around the second guide post 319 on the lower side of the second baffle 313, which is fixed to it.

[0037] After the road surface 11 is broken up, the workers can directly clean the broken road surface 11 within the rectangular frame using the excavator head 308 and the vent shell 311. The specific process is as follows: The operator first uses a remote control to control the electric slider on the first electric slide rail 4, which drives the sixth electric slide rail 301 and its components to slide left and right, thus controlling the left and right position of the first fixed plate 304. Then, by controlling the electric slider on the sixth electric slide rail 301, the operator drives the third support block 302 and its components to slide back and forth, thereby controlling the front and back position of the first fixed plate 304. Finally, by controlling the extension or retraction of the telescopic end of the fifth hydraulic push rod 303, the operator moves the first fixed plate 304 along with its components, thus controlling the up and down position of the first fixed plate 304. By using these combined control methods, the operator positions the excavator head 308 on the first fixed plate 304 to the right side of the rectangular frame. At this point, the operator controls the electric rotating shaft via the remote control. The rotation of 307 controls the rotation of the excavator head 308. When the excavator head 308 is in a vertical position, the worker pushes the excavator head 308 downward through the third electric push rod 305, inserting it into the front right side frame of the rectangular frame. Then, the worker controls the first electric slide rail 4 to move the excavator head 308 to the left, and controls the excavator head 308 to rotate into an inclined state during the movement, pushing and shoveling up the broken road surface 11 inside the rectangular frame until the excavator head 308 moves to the left side frame of the rectangular frame. The worker controls the excavator head 308 to move upward through the third electric push rod 305, pushing the broken road surface 11 inside the excavator head 308 out of the rectangular frame. This movement is repeated until the rectangular frame is clean. Then, the worker collects the road surface 11 that has been cleared from the outside of the rectangular frame.

[0038] While the workers were clearing the broken road surface 11 within the rectangular frame using the excavator head 308, the workers also moved the excavator head 308 to the left using the first fixing plate 304. When the vent shell 311 moved into the rectangular frame, the workers controlled the fourth electric push rod 306 to extend via a remote control, causing the second fixing plate 309 to move the vent shell 311 down into the rectangular frame. At the same time, the workers activated the vacuum cleaner via the remote control, which sucked up the small gravel and dust that had not been scooped up on the right side of the excavator head 308 within the rectangular frame through the vent shell 311. This cleaned the inside of the rectangular frame while preventing secondary pollution. Subsequently, the vent shell 311 followed the excavator head 308, repeatedly moving from the right side of the rectangular frame to the left side, thus completing the cleaning within the rectangular frame.

[0039] When the vent shell 311 repeatedly cleans the rectangular frame following the excavator head 308, normally only the lower vent of the vent shell 311 is open. When the vent shell 311 is located at the left and right side lines of the rectangular frame, the first baffle 312 moves upward under the pressure of the adjacent left and right side lines of the rectangular frame (i.e., the pressure of the first right-angle frame 8 and the second right-angle frame 9 on the left and right sides). At this time, the reset elastic element connected to it is compressed and stored. Taking the first baffle 312 on the right side moving upward as an example, the first baffle 312 on the right side of the vent shell 311 moves upward under the pressure of the first right-angle frame 8 and the second right-angle frame 9 on the right side, so that the vent on the right side of the vent shell 311 opens. At this time, the vent shell 311 not only draws air from below to clean, but also draws air from the right vent to clean the right side of the road surface 11 in the rectangular frame.

[0040] When the first baffle 312 on the right moves upward, it drives the connected first steel wire 316 to move upward as well. The first steel wire 316 passes around the cooperating first guide post 315 and pulls the end of the connected first windproof cloth roll 314 on the left. The first windproof cloth roll 314 is pulled out to the left and laid flat. The reset torsion spring connected to the first windproof cloth roll 314 stores force and blocks the lower left vent of the vent housing 311. The blocking area of ​​the first windproof cloth roll 314 is proportional to the upward movement distance of the first baffle 312. That is, when the vent on the right side of the vent housing 311 is opened... The left side of the air vent on the lower side of the vent shell 311 is blocked by the same area, ensuring that the air vent area of ​​the vent shell 311 is always maintained within a fixed range. This prevents the actual working efficiency of the vacuum cleaner from being affected by the expansion of the suction area, and ensures that the vacuum cleaner's suction effect is stable. When the first baffle 312 on the right side moves away from the right edge of the rectangular frame, the first baffle 312 on the right side is reset under the push of the connected reset elastic element. The first steel wire 316 is released, and the reset torsion spring adjacent to the first windproof cloth roll 314 on the left side is reset, which drives the windproof cloth on the first windproof cloth roll 314 to automatically rewind and reset.

[0041] When the first baffle 312 on the left is squeezed by the left edge of the rectangular frame, the first windproof cloth roll 314 on the right is similarly pulled out to the left, keeping the ventilation area of ​​the ventilation shell 311 within a fixed range. When the second baffles 313 on the front and rear sides are squeezed by the front and rear edges of the rectangular frame respectively, the two second windproof cloth rolls 318 operate according to the above principle, respectively blocking the front and rear sides of the lower ventilation port of the ventilation shell 311, keeping the ventilation area of ​​the ventilation shell 311 always within a fixed range, and maintaining the vacuum cleaner's dust collection effect.

[0042] After the broken road surface 11 is cleaned, the staff uses a remote control to stop the vacuum cleaner and start the dryer. The dryer is still connected to the ventilation shell 311 and dries the road surface 11 within the rectangular frame according to the same principle as when vacuuming.

[0043] Once the cleaning and drying work is completed, the staff will reset the vent housing 311 and the excavator head 308 and proceed with the next steps.

[0044] Example 3: Based on the reference in Example 2, such as Figure 2 , Figure 3 , Figure 14 and Figure 15It also includes a material feeding mechanism for filling cold patching material within a rectangular frame. The feeding mechanism is electrically connected to a remote control device and is located inside the carriage 2. The feeding mechanism includes two mirror-distributed second telescopic rods 401, both slidably connected within the carriage 2. The two second telescopic rods 401 are jointly fixed to a hopper 402, allowing the hopper 402 to move freely within the carriage 2 via the two second telescopic rods 401. The hopper 402 contains a solenoid valve for controlling the material feeding. The four electric sliders of the two first electric slide rails 4 from left to right are jointly fixed to a seventh electric slide rail 403, which is electrically connected to the remote control device. The order of the components fixed to the four electric sliders on the two first electric slide rails 4 follows the work sequence during construction. To reduce the time required for adjusting various components during the overall construction process, the seventh electric slide rail 403 is slidably connected to the fourth support block 404 via an electric slider. The center of the fourth support block 404 is rotatably connected to an electric turntable 405 electrically connected to a remote control device. The center of the electric turntable 405 is slidably connected to a telescopic guide pipe 406 connected to the hopper 402. The fourth support block 404 is fixedly connected to a sixth hydraulic push rod 407 with its telescopic end pointing downwards. The telescopic end of the sixth hydraulic push rod 407 is fixedly connected to a fifth support block 408 rotatably connected to the telescopic guide pipe 406. The telescopic guide pipe 406 is fixedly connected to and connected to a square guide pipe 409. The left side of the square guide pipe 409 is fixedly connected to a fifth electric push rod 410 electrically connected to a remote control device via a support rod. The telescopic end of the push rod 410 is rotatably connected to a rotating nozzle 411 electrically connected to a remote control device. The rotating nozzle 411 is connected to a hydraulic pump for filling adhesive via a hose. The hydraulic pump is electrically connected to the remote control device. The telescopic end of the fifth electric push rod 410 drives the rotating nozzle 411 to move up and down. The rotating nozzle 411 rotates to evenly spray adhesive onto the inner wall of the road surface 11 within the rectangular frame. Because the square guide pipe 409 is located behind the rotating nozzle 411 in the horizontal movement direction, the rotating nozzle 411 always sprays the adhesive onto the area where the cold patch material is about to be filled, increasing the adhesive bonding effect. A support frame 412 is fixedly connected to the right side of the square guide pipe 409. The support frame 412 is slidably connected to a slab 413 via a support rod. The slab 413 is close to the rotating nozzle 411. One side of the moving nozzle 411 has an open U-shaped plate, used to scrape the cold patch material flat and push excess cold patch material to move along with the square guide tube 409, stabilizing and controlling the filling amount of cold patch material, ultimately ensuring that the cold patch material is evenly filled to the height of the two first right-angle frames 8 and the two second right-angle frames 9. A fourth elastic element 414, which is a spring, is fixedly connected between the spreading plate 413 and the support frame 412. A baffle plate 415 is fixedly connected to the upper side of the spreading plate 413. The baffle plate 415 is slidably connected to the support frame 412 and to the square guide tube 409. The baffle plate 415 is provided with a through hole that mates with the square guide tube 409, used to adjust the speed at which the cold patch material falls from the square guide tube 409. When too much cold patch material accumulates...Excessive pressure from the spreading plate 413 causes the baffle plate 415 to move. The horizontal movement of the baffle plate 415 reduces the connection area between the square guide tube 409 and the baffle plate 415, thereby slowing down the rate at which the square guide tube 409 falls for cold replenishment.

[0045] After the workers cleared the broken pavement 11 inside the rectangular frame, they filled the rectangular frame with cold patching material through the square guide pipe 409. The specific process is as follows: The operator controls the electric slider of the first electric slide rail 4 to drive the seventh electric slide rail 403 and its components to slide left and right along the first electric slide rail 4, thereby controlling the left and right position of the square guide tube 409. The operator also controls the electric slider of the seventh electric slide rail 403 to drive the fourth support block 404 to slide back and forth along the seventh electric slide rail 403, thereby controlling the front and back position of the square guide tube 409. Furthermore, the operator controls the extension and retraction of the components on the sixth hydraulic push rod 407 to control the up and down position of the square guide tube 409. Finally, the operator controls the rotation of the electric turntable 405 to control the square guide tube 409. The rotation direction of 9 and its components is controlled by the operator using the above-mentioned control methods in combination, and by opening the solenoid valve on the hopper 402, so that the cold replenishment material in the hopper 402 falls into the rectangular frame through the telescopic guide pipe 406 and the square guide pipe 409. The position and direction of the square guide pipe 409 are controlled so that the square guide pipe 409 moves sequentially along the edge of the rectangular frame and moves towards the center of the rectangular frame in an approximately spiral manner to replenish the cold replenishment material. When the square guide pipe 409 moves, the hopper 402 moves together with the square guide pipe 409 through two second telescopic rods 401.

[0046] As workers fill the rectangular frame with cold patch material through the square guide pipe 409, a remote control device simultaneously activates the fifth electric push rod 410 and the hydraulic pump for filling the adhesive. Simultaneously, the remote control device controls the rotating nozzle 411 to begin rotating. Taking the square guide pipe 409 moving from right to left along the front side of the rectangular frame as an example, the telescopic end of the fifth electric push rod 410 continuously extends and retracts, driving the rotating nozzle 411 to move up and down continuously. The rotating nozzle 411 remains in a rotating state, ensuring that the adhesive delivered by the hydraulic pump is evenly sprayed onto the left side of the square guide pipe 409. At this time, because the square guide pipe 409 is continuously filling the rectangular frame with cold patch material, the adhesive is sprayed not only onto the sides of the roadbed and pavement 11 within the rectangular frame but also onto the falling cold patch material, increasing the bonding strength between the cold patch material and the adhesive, facilitating thorough adhesion of the cold patch material after subsequent compaction.

[0047] When the worker controls the square guide tube 409 to fill the rectangular frame with cold patch material, the square guide tube 409 feeds material quickly to fill the gaps in the rectangular frame. As the square guide tube 409 moves, the spreading plate 413 moves along with the square guide tube 409 to spread out any excess accumulated cold patch material. The specific steps are as follows: Taking the square guide tube 409 moving from right to left along the front side of the rectangular frame as an example, the spreading plate 413 moves to the left along with the square guide tube 409. Initially, the operator needs to wait for the cold patch material to accumulate before controlling the movement of the square guide tube 409 to prevent insufficient cold patch material from causing uneven spreading. As the square guide tube 409 moves to the left, the spreading plate 413 is compressed by the accumulated cold patch material, slowing down its movement to the left. That is, the spreading plate 413 moves to the left relative to the square guide tube 409, compressing the fourth elastic element 414. The more cold patch material accumulates under the square guide tube 409, the more the spreading plate 413 moves relative to the square guide tube 409. The further the leftward movement, the greater the compression of the fourth elastic element 414. At this time, the spreading plate 413 moves together with the baffle plate 415. The baffle plate 415 moves to the left, reducing the connecting area between the square guide tube 409 and the baffle plate 415, thereby reducing the amount of cold patch material falling and preventing a large amount of cold patch material from accumulating and overflowing. At the same time, when the cold patch material accumulation on the lower side of the square guide tube 409 is too small and will not be enough for spreading, the fourth elastic element 414 is subjected to less compressive force and begins to press the spreading plate 413 to the left and reset. The spreading plate 413 moves to the left together with the baffle plate 415, increasing the amount of cold patch material falling from the square guide tube 409.

[0048] When the cold patch material inside the rectangular frame is spread out until its upper end is aligned with the two first right-angle frames 8 and the two second right-angle frames 9, the cold patch material filling work is completed. The workers then reset the square guide tube 409 and its components by reversing the operation described above, and compact the cold patch material inside the rectangular frame.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
