Step S2: starting the pressing part to drive the pressing plate 39 to move, pressing the asphalt into the crack through the discharge pipe 4, and enabling the asphalt to uniformly flow around the crack through the reaction force of the moving assembly;
the method specifically comprises the following steps: move through clamp plate 39 down-pressure, drive baffle 25 downstream, baffle 25 that moves down drives spline housing 28 and puddler 29 and slides along spline axial region 27 surface, thereby make puddler 29 follow clamp plate 39 synchronous motion, avoid clamp plate 39 to push down the in-process and be blocked by puddler 29, the pitch that leads to puddler 29 below can't be pushed out, guarantee the unloading quality, make puddler 29 relative position keep unchangeable, improve follow-up stirring quality, pitch falls in the crack from discharging pipe 4, and use discharging pipe 4 to pile up around to the crack as the center. When the asphalt accumulation height is greater than the preset height between the bottom of the moving block 9 and the bottom of the crack, asphalt can extrude the bottom of the moving block 9, the moving block 9 is pressed to move upwards to enable the first spring 10 to contract, and the asphalt is pressed by the reaction force of the first spring to fully fill the space in the crack and is continuously compacted in the space. When the moving block 9 moves upwards, the supporting rod 8 is driven to move, the supporting rod gradually extends into the groove 35 until the supporting rod abuts against the bottom of the groove 35, compaction of the moving block 9 on the asphalt below is achieved, the moving block 9 above the crack continuously moves around the crack along with pressure, the moving block 9 above the crack sequentially moves until all the moving blocks 9 above the crack all move the maximum distance, the asphalt is uniformly distributed in the crack at the moment, and the asphalt is compacted by the moving block 9, and the crack pouring quality is improved.
Step S3: the moving component moves to a sufficient distance and then is matched with the conductive component, the control pressure plate 39 resets, and the blanking is stopped for subsequent use.
The method specifically comprises the following steps: in the bracing piece 8 on all movable blocks 9 all stretched into recess 35, and the circuit intercommunication when laminating with conducting strip 37, and with signal transmission to controller 32, controller 32 control pneumatic cylinder 5 and the second 31 pars contractilis of pneumatic cylinder reset, thereby drive equipment and resume to initial position, the follow-up use of being convenient for, thereby realize equipment automatic re-setting after the completion of repairing, need not the manual observation crack department cementation of fissures condition, avoid pitch to spill over, also can guarantee that the volume of pouring into pitch can not be too little.
