Preferably, the installation base 31 is provided with a rotary groove 314, the rotary groove 314 is internally provided with a rolling component 34, the rolling component 34 comprises a rolling roller 341, two sides of the rolling roller 341 are provided with a rolling roller bracket 342, the rolling roller 341 is movably connected with the rolling roller bracket 342, the rolling roller bracket 342 is tightly connected with the installation base 31, the bottom side of the rolling roller 341 is contacted with the road surface, and the rolling roller 341 is movably connected with the wall surface of the rotary groove 314.
The roll 341 is cylindric, the bottom side rolls on the road surface, roll the breakage to road surface impurity through whole car weight, through roll 341, fixing base 41 and the combination of mount pad 31 outside, be close to automobile body 11 one side with batching box 21's mixing chamber 211 and carry out the shutoff, through one-way blocking, make the air can not get into air cavity 312 from automobile body 11 one side, reduce air cavity 312 air source, guarantee the attraction guide effect to the interior gas of mixing chamber 211, carry out the gyration support to roll 341 through roll support 342, prevent through fastening connection that the pine from taking off.
As optimization, the air outlet 311 is obliquely arranged, so that the guided air flow is quickly reversed to impact the inner wall of the air cavity 312, the power of larger particles is lost through impact, the larger particles fall into the accommodating groove 313 under the action of gravity, and the larger particles are recovered to prevent the sealing effect from being influenced.
For optimization, the stirring blades 53 are spirally arranged to ensure the axial flow performance of the seal material along the stirring shaft 52.
The working principle of the invention is as follows: when sand-containing fog is paved, the lower part of a mixing cavity 211 is divided into two chambers by a partition plate 26, a spraying gap is reserved between the upper end of the partition plate 26 and the bottom side of a spray head 25, atomized asphalt is divided into two parts after the emulsified asphalt is atomized and sprayed by the spray head 25, the atomized asphalt in the mixing cavity 211 close to a vehicle body falls and condenses laterally along the advancing direction of the vehicle body 11 under the action of pressure after the partition plate 26 is cut off, and the atomized asphalt and fine sand together perform primary sealing on a road surface; the air inlet 214 is communicated with the air cavity 312 through the flow passage 213, so that negative pressure is generated at the air inlet 214, the atomized asphalt is atomized in the mixing cavity 211 far away from the vehicle body 11, the atomized asphalt is attracted to two sides through the air inlets 214 on the two sides, the atomized asphalt is condensed along the direction vertical to the traveling direction of the vehicle body, and secondary sealing is carried out; the two sides of the bottom side of the mixing cavity 211 are self-closed, the front part is blocked by the fixed seat 41, the mounting seat 31 and the rolling roller 341, air can only flow in through a gap between the rear part of the mixing cavity 211 and the road surface, air is pumped by the air pump 32, a negative pressure area is formed in the air cavity 312, when the road surface is sunken such as ruts and the like, an overflowing section exists between the mounting seat 31 and the road surface, air flow entering the mixing cavity from the outside flows flatly along the road surface, the flowing speed is kept stable, the pressure is reduced along with the increase of the flow speed, the pressure at the sunken part is reduced along with the movement of the mounting seat 31 to the sunken part along with the vehicle body, a low-pressure air chamber is formed, and as the overflowing section area is increased, the pressure in the air cavity 312 is increased, the air pump is closed, so that the mixture of atomized asphalt and fine sand moves to the sunken part under the action of pressure, and the repair of the road surface defects is completed; air pump 22 inlet end passes through gas outlet 311 and air cavity 312 intercommunication, produce the negative pressure in making air cavity 312, thereby make mixing chamber 211 and outside air constantly inhaled, retrain the pitch of atomizing through the pressure differential, prevent high temperature pitch loss in mixing chamber 211, drive the inside pitch of atomizing switching-over through the outside air laminar flow, the slope whereabouts, because pitch of atomizing self possess gravity, change flow direction through the air lateral force, thereby make pitch of atomizing lay on the road surface, adjust pitch moving speed of atomizing through adjusting air cavity 312 internal pressure, thereby adjust fog seal thickness.
