[0002] Asphalt pavement refers to various types of pavement paved with road asphalt materials mixed into mineral materials; the asphalt binder improves the ability of paving aggregate to resist damage to the road surface caused by driving and natural factors, making the road surface smooth, dust-free, waterproof and durable; therefore, asphalt pavement is the most widely used high-grade pavement in road construction.

[0003] However, after a period of use, asphalt pavement is eroded by vehicles and rain, and numerous cracks will appear on the surface of the asphalt pavement. If the cracks are not repaired in time, they will continue to expand under further vehicle crushing.

[0004] At present, there are more or less moisture, dust, debris and sundries in the cracks. Uncleaned and dry crack walls will lead to reduced adhesion between the cracks and the filling materials, which may cause the filling materials to fall out and make the crack filling ineffective. Therefore, in order to ensure the effectiveness and durability of the crack filling, the cracks need to be thoroughly cleaned and partially cleaned, and the broken and deformed parts need to be sheared and cleaned before asphalt repair.

[0018] Beneficial effects of the present invention:

[0019] The present invention adapts the adjusting mechanism to the crushing mechanism, the suction mechanism and the asphalt storage mechanism, and then drives the crushing mechanism, the suction mechanism and the asphalt storage mechanism one by one to adjust the positions, so that the crushing mechanism, the suction mechanism and the asphalt storage mechanism are adapted to the cracks. At the same time, the crushing mechanism, the suction mechanism and the asphalt storage mechanism are used to respectively clean the cracks, absorb the debris and pour the asphalt.

[0020] The present invention starts motor 2 and motor 1 through the design of the adjustment mechanism through the controller on the side of the moving frame. Motor 2 drives the nut moving frame to move in the driving cavity through screw rod 2. The movement of the nut moving frame drives the docking plate to move to the corresponding rotating disk, and then the docking plate and the docking groove are docked together. Thereafter, motor 1 drives the driven gear to rotate through the driving gear, the driven gear drives the docking plate to rotate through the rotating shaft, the docking plate drives screw rod 1 to rotate through the rotating disk, and screw rod 1 starts the corresponding crushing mechanism, suction mechanism and asphalt storage mechanism to move and work through the threaded action with the nut moving block.

[0021] The present invention, through the design of the crushing mechanism and the arrangement of the separate components of the counterweight impact assembly and the crushing assembly, can ensure the progress of the crushing work while increasing the rising stroke of the counterweight impact assembly. Through the arrangement of the clamping parts and the crushing head, the crushing heads of different shapes can be replaced according to the conditions of the cracks, thereby improving the crushing efficiency.

[0022] The present invention adopts the design of a counterweight impact assembly and drives the half gear to rotate through a driving motor. The half gear drives the vertical plate and the sliding plate to rise by engaging with the rack plate. When the half gear is disengaged from the rack plate, the vertical plate and the sliding plate are accelerated to descend under the action of gravity, so that the bottom of the vertical plate is connected with the crushing assembly, driving the crushing assembly to descend rapidly, thereby realizing crushing and shearing work.

[0023] The present invention adopts the design of the crushing assembly, and the bottom of the vertical plate is connected with the groove at the top center of the impact seat. Under the damping action of the damping groove and the damping block, the impact seat will not drop instantly, so that there is a fitting process between the bottom of the vertical plate and the impact seat. During this process, the impact seat will gradually separate from the plug-in plate located at the top of the installation groove when it descends. In this case, the damping spring pushes the sliding seat to move, thereby driving the end of the sliding seat to be inserted into the groove and clamped together with the clamping groove at the bottom of the side of the vertical plate, thereby connecting and fixing the vertical plate and the impact seat, thereby pushing the crushing rod at the bottom of the impact seat to drop quickly, and then shearing the inside of the crack.

[0024] The present invention uses the design of the clamping piece and the crushing head to pull the traction rope downward, and the two ends of the traction rope pull the guide slide plates from both sides respectively. The guide slide plates slide in the inner cavity and pull the sleeve and the toggle block located on the outside of the connecting seat to move, thereby causing the positioning block on the side of the toggle block to disengage from the positioning groove on the turntable. Subsequently, the turntable is pushed toward the connecting seat, and the turntable will move a short distance into the rotation groove under the limit of the limit block, thereby causing the end of the rotating shaft to be inserted into the slot on the shaft rod and locked by the locking block and the locking groove. Subsequently, the turntable is turned to drive the transmission gear to rotate, and the rotation of the transmission gear will drive the inclined rack plates on both sides to move out of the limit groove, thereby releasing the connection between the crushing head and the connecting seat.

[0025] The present invention starts the dust suction fan through the design of the suction mechanism. The dust suction fan sucks up the debris in the crack through the dust suction pipe under negative pressure suction, and then transports it to the inside of the collection box through the output pipe. The debris is directly mixed into the water flow inside the collection box, thereby realizing the collection of waste debris.

[0026] The present invention adopts the design of the damping groove and the damping block, so that when the connection state between the vertical plate and the impact seat is released, the impact seat will not fall under the damping effect of the damping groove and the damping block.

The above-mentioned crushing mechanism 2, suction mechanism 3 and asphalt storage mechanism 4 are all adjusted in position through the adjustment mechanism when working.

[0050] The operation process of the adjustment mechanism is as follows: the motor 2 63 and the motor 1 57 are started by the controller on the side of the moving frame 1, and the motor 2 63 drives the nut moving frame 56 to move in the driving chamber 51 through the screw 2 62, and the movement of the nut moving frame 56 drives the docking plate 61 to move to the corresponding rotating disk 54, and then docks together through the docking plate 61 and the docking groove 55. Thereafter, the motor 1 57 drives the driven gear 60 to rotate through the driving gear 58, and the driven gear 60 drives the docking plate 61 to rotate through the rotating shaft 59, and the docking plate 61 drives the screw 1 53 to rotate through the rotating disk 54, and the screw 1 53 starts the corresponding crushing mechanism 2, the suction mechanism 3 and the asphalt storage mechanism 4 to move and work through the threaded action with the nut moving block 73.

[0051] The operation process of the crushing mechanism 2 is as follows: the half gear 12 is driven to rotate by the driving motor, and the half gear 12 drives the vertical plate 10 and the sliding plate 9 to rise by meshing with the rack plate 11. When the half gear 12 is disengaged from the rack plate 11, under the action of gravity, the vertical plate 10 and the sliding plate 9 are accelerated to descend under the action of gravity, so that the bottom of the vertical plate 10 is connected with the groove 14 at the top center of the impact seat 13. Under the damping action of the damping groove 49 and the damping block 50, the impact seat 13 will not drop instantly, so that there is a fitting process between the bottom of the vertical plate 10 and the impact seat 13. During this process, the impact seat 13 will gradually disengage from the plug-in plate 21 located at the top of the installation groove 8 when it descends. In this case, the damping spring 23 pushes the sliding seat 17 to move, thereby driving the end of the sliding seat 17 to be inserted into the groove 14 and clamped with the clamping groove at the bottom of the side of the vertical plate 10, thereby The vertical plate 10 is connected and fixed to the impact seat 13, thereby pushing the breaker rod 28 at the bottom of the impact seat 13 to quickly descend, and then shearing the inside of the crack. Subsequently, the half gear 12 rotates again to drive the vertical plate 10 to rise. The rise of the vertical plate 10 drives the impact seat 13, the U-shaped seat 27 and the breaker rod 28 to rise until the impact seat 13 moves into the installation groove 8, and the plug-in plate 21 at the top of the installation groove 8 is inserted into the active cavity 15 through the plug-in hole 16, and pushes the sliding seat 17 to move and be stored in the active cavity 15 by squeezing the inclined plate 20, and the connection with the impact seat 13 is released. At this time, under the action of the half gear 12 and the rack plate 11, the vertical plate 10 and the sliding plate 9 continue to rise, and the impact seat 13 will not fall under the damping action of the damping groove 49 and the damping block 50, until the sliding plate 9 rises to the top and disengages from the half gear 12, and then descends again under the action of its own weight, and then repeats the above process.

[0052] The operation process of the suction mechanism 3 is as follows: the dust suction fan 67 is started, and the dust suction fan 67 sucks the debris in the crack through the dust suction pipe 68 under negative pressure suction, and then transports it to the inside of the collection box 71 through the output pipe 69. The debris is directly mixed into the water flow inside the collection box 71, thereby realizing the collection of waste debris.

[0053] At the same time, the crushing head at the bottom of the connecting seat 25 can be replaced by the clamping piece, that is, the traction rope 48 is pulled downward, and the two ends of the traction rope 48 pull the guide slide plate 44 from both sides respectively, and the guide slide plate 44 slides in the inner cavity 42 and pulls the sleeve 45 and the toggle block 46 located on the outer side of the connecting seat 25 to move, thereby making the positioning block 47 on the side of the toggle block 46 disengage from the positioning groove 39 on the rotating disk 38, or using an auxiliary tool to push the toggle block 46 to both sides at the same time. Subsequently, the rotating disk 38 is pushed toward the connecting seat 25. The rotating disk 38 will move a short distance into the rotating groove under the limit of the limit block 36, thereby making the end of the rotating shaft 35 inserted into the slot 33 on the shaft rod 32, and locked by the locking block 34 and the locking groove 37. Then, the transmission gear 31 is driven to rotate by rotating the rotating disk 38. The rotation of the transmission gear 31 will drive the inclined rack plates 29 on both sides to move out of the limit groove, and the connection relationship between the crushing head and the connecting seat 25 can be released.

[0054] In addition, when the damping spring 230 is damaged and cannot be repaired in time, at this time, the turntable 38 is pushed toward the connecting seat 25 so that the end of the rotating shaft 35 is inserted into the slot 33 on the shaft 32, and then the transmission gear 31 is driven to rotate by rotating the turntable 38. The rotation of the transmission gear 31 will drive the inclined rack plates 29 on both sides to move and insert into the limiting grooves on the inner wall of the U-shaped seat 27, and then the turntable 38 is clamped and limited by the positioning blocks 47 on both sides, thereby limiting the extended inclined rack plate 29, achieving a temporary limiting effect, gaining a short replacement time for the device and ensuring the working efficiency of the device.

[0055] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
