[0001] The invention relates to the technical field of asphalt highway maintenance, and in particular to asphalt highway maintenance pothole processing equipment. Background Art
[0002] As we all know, potholes are a typical defect of asphalt pavement, which seriously affects the smoothness and comfort of the road surface. If not repaired in time, the road surface will be damaged faster under the combined effects of traffic load and water, resulting in an increase in maintenance costs and seriously endangering the safety of drivers. When potholes appear on the road, the staff usually manually transport the asphalt to the pothole, then fill the pothole and use tools to manually repair and fill the pothole.
[0003] Therefore, when small potholes appear on the asphalt pavement, cold patch materials are generally used to fill the potholes to make the road surface smooth again. However, after the post-fill asphalt and the road surface asphalt are fused, the gap between the two asphalt pavements constructed at different times is larger, allowing rainwater to enter the gap and cause damage to a larger area of the asphalt pavement, making the repair easily ineffective. Summary of the invention

DETAILED DESCRIPTION
[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0022] Example 1: Reference Figure 1-6 , an asphalt road maintenance pothole treatment equipment, including a shell 1, a partition 2 is arranged in the shell 1, the partition 2 divides the shell 1 into a first cavity 3, a second cavity 4, and a third cavity 5, a placement groove 6 is opened on the shell 1 at the bottom of the first cavity 3 and the second cavity 4, the placement groove 6 is connected to the second cavity 4, a movable baffle 7 is arranged in the placement groove 6, a hydraulic telescopic rod 8 is arranged between the movable baffle 7 and the placement groove 6, a knocking component is arranged in the third cavity 5, a sealing cover 9 is arranged on the top of the shell 1, and a sealing cover 9 is arranged in the second cavity 4. A cold patch material is placed, a servo motor 10 is arranged in the first cavity 3, and the knocking assembly includes a knocking column 15 placed in the third cavity 5, one end of the knocking column 15 passes through the shell 1, and the other end of the knocking column 15 is installed with a hinge seat 16, and a crank 17 is hinged on the hinge seat 16. A crankshaft 18 is installed in the third cavity 5 through a bearing, and one end of the crank 17 is hinged on the crankshaft 18. A connecting mechanism is arranged between the crankshaft 18 and the servo motor 10, a connecting frame 11 is installed at the bottom of the shell 1, and a moving assembly 12 is arranged at the bottom of the connecting frame 11.
[0023] A plurality of weight blocks are disposed in the first cavity 3 and the second cavity 5 . The plurality of weight blocks make the device more stable, thereby reducing the probability of displacement of the device during the operation of the knocking column 15 .
[0024] Combined with Figure 4 It can be seen that the top of the movable baffle 7 is arranged in an inclined shape, so that the cold patch material in the second cavity 4 can fall more easily into the pothole area of the road surface.
[0025] After the device is moved to the position to be repaired through the moving component 12, the hydraulic telescopic rod 8 is started, and the extension rod of the hydraulic telescopic rod 8 will move with the moving baffle 8 in the placement groove 6, so that the cold patch material in the second cavity is placed on the pothole position of the road surface, and the placement is stopped after observing that the placed cold patch material exceeds the road surface, and then the device is moved again, so that the vertical projection of the knocking column 15 is located in the area where the cold patch material is placed, and the servo motor 10 is started. The servo motor 10 will rotate the crankshaft 18 through the connecting mechanism, and the crankshaft 18 will rotate one end of the crank 17 during the rotation process, and the other end of the crank 17 will be hinged It is connected to the articulated seat 16, and the articulated seat 16 is fixedly installed on the knocking column 15. The knocking column 15 slides through the shell 1, so that the crank 17 will drive the knocking column 15 to reciprocate. During the reciprocating movement of the knocking column 15, the cold patch material area will be knocked, so that the cold patch material area is compacted. During the compaction of the cold patch material area, part of the cold patch material will penetrate into the original pavement area, so that the later asphalt and the pavement asphalt are fused, and the gap between the asphalt pavements at different construction times is reduced, so that the asphalt pavement is not easily damaged after rainwater enters the gap, thereby achieving a good repair effect.
[0026] Embodiment 2: In embodiment 1, the device is prone to large-scale movement or even tipping during the operation of the knocking column 15. Based on embodiment 1, the device is optimized. Figure 1-6 A push rod 13 is provided on one side of the connecting frame 11, and a handle 14 is provided on one side of the outer wall of the shell 1. Both the push rod 13 and the handle 14 are provided with anti-slip grooves.
[0027] Combined with Figure 1-6 It can be seen that the push rod 13 and the handle 14 are located on both sides of the device, so that when the push rod 13 and the handle 14 are grasped by two construction workers, the device is not likely to move during the construction process.
[0028] Embodiment 3: In embodiment 1, the crankshaft 18 rotates with the crank 17 at a faster speed. Based on embodiment 1-2, the optimization is performed. Figure 1-6 The connecting mechanism includes a rotating shaft 19 installed on the partition 2 through a bearing, one end of the rotating shaft 19 is connected to the output shaft of the servo motor 10, and the other end of the rotating shaft 19 is installed with a first gear 20. A second gear 21 is installed on the crankshaft 18. The first gear 20 is meshed with the second gear 21, and the transmission ratio between the first gear 20 and the second gear 21 is 1:4.
[0029] By setting the meshing of the first gear 20 and the second gear 21, and combining the transmission ratio between the first gear 20 and the second gear 21 as 1:4, after the output shaft of the servo motor 10 rotates the rotating shaft 19, the rotating shaft 19 accelerates the rotation speed of the crankshaft 18 through the meshing of the first gear 20 and the second gear 21, so that the frequency of movement of the crank 17 is increased, thereby improving the working efficiency of the device. Moreover, after the first gear 20 and the second gear 21 are meshed, the stress at the knocking column 15 is too large, causing problems in the operation of the device, and the first gear 20 and the second gear 21 will have broken teeth, thereby protecting other components of the knocking mechanism.
[0030] Embodiment 4: In embodiment 1, the cold patch material can be placed in the second cavity 4 only after the sealing cover 9 is removed. The operation is too complicated. Based on embodiments 1-3, the optimization is performed. Figure 1-6 The vertical projection of the sealing cover 9 covers the first cavity 3 and the third cavity 5 , a flap 22 is hingedly connected to the sealing cover 9 , and the vertical projection of the flap 22 is located on the second cavity 4 , and a blocking mechanism 23 is provided on the sealing cover 9 , which blocks the flap 22 .
[0031] By adding a flap 22 at the sealing cover 9, the cold patch material is more easily added to the second cavity 3, thereby facilitating the replenishment of raw materials to the device; and during the operation of the device, the blocking mechanism 23 prevents the flap 22 from shaking, thereby increasing the safety of the device.
[0032] The overall process is as follows: after the device is moved to the position to be repaired through the moving assembly 12, the flap 22 is opened, and the cold patch material is added into the second cavity 3. The flap 22 is prevented from shaking by the blocking mechanism 23, and the hydraulic telescopic rod 8 is started. The extension rod of the hydraulic telescopic rod 8 will move with the mobile baffle 8 in the placement groove 6, so that the cold patch material in the second cavity is placed in the pothole position of the road surface. After observing that the cold patch material placed exceeds the road surface, the placement is stopped. Then the device is moved again, so that the vertical projection of the knocking column 15 is located in the area where the cold patch material is placed. After the push rod 13 and the handle 14 are grasped by two construction workers, the servo motor 10 is started. After the output shaft of the servo motor 10 rotates the rotating shaft 19, the rotating shaft 19 passes through the first gear 20 and the second gear 21. The engagement increases the rotation speed of the crankshaft 18 and the frequency of the movement of the crank 17. During the rotation of the crankshaft 18, one end of the crank 17 will rotate with it. The other end of the crank 17 is hinged on the hinge seat 16, and the hinge seat 16 is fixedly mounted on the knocking column 15. The knocking column 15 slides through the shell 1, so that the crank 17 will reciprocate with the knocking column 15. During the reciprocating movement of the knocking column 15, the cold patch material area will be knocked, so that the cold patch material area is compacted. During the compaction of the cold patch material area, part of the cold patch material will penetrate into the original pavement area, so that after the later asphalt and the pavement asphalt are fused, the gap between the two asphalt pavements at different construction times is reduced, so that the asphalt pavement is not easily damaged after rainwater enters the gap, thereby achieving a good repair effect.
