EXAMPLE five

As shown in fig. 1 to 4, in a specific embodiment, the vehicle 2 is a muck truck, the cavity 102 of the tank assembly 1 is a tail tank of the muck truck, a discharge hole 104 is formed in an end of the cavity of the tail tank, which is away from the cab, a door 110 of the tail tank is openably and closably disposed at the discharge hole 104, the sealing member 112 is an inflatable sealing strip, the inflatable sealing strip is mounted on the door 110 and is mounted on the left, right and lower three edges of the door 110, and the inflatable sealing strip is inflatable when sealing is required and is in an deflated and retracted state at ordinary times. The sealing surface 106 is arranged at the discharge port 104 of the tail box, the inner wall of the cavity 102 is provided with the protruding structure 108 along the sealing surface 106, the protruding structure 108 protrudes out of the sealing surface 106 along the direction of the discharge port 104 deviating from the inside of the cavity 102, when high-humidity muck is transported, as shown in fig. 3, the discharge port 104 is closed by the door body 110, the inflated sealing strip abuts against the sealing surface 106 to play a sealing role, and water in the muck cannot flow out from a gap between the door body 110 and the cavity 102. After the muck truck reaches the destination, as shown in fig. 4, the door 110 opens the discharge hole 104, no muck or garbage remains on the inflatable sealing strip in the process of dumping the muck or garbage, and no muck or garbage remains on the sealing surface 106 under the protection of the convex structure 108. After the dregs or garbage are poured out, as shown in fig. 3, the door 110 closes the discharge hole 104 again, and as no dregs or garbage remains on the inflatable sealing strip and the sealing surface 106, the door 110 does not extrude sharp dregs or garbage to puncture the inflatable sealing strip in the process of closing the discharge hole 104, so that the structure can still really play a role in sealing in the next transportation process.

The utility model provides a dregs car is when transporting the dregs that water content is high, and the inflatable sealing strip aerifys the clearance between the cavity 102 AND gate body 110 of filling the tail-box, should aerify the sealing strip and install on the tail-box door, and the dregs car can not the jamming and remain building rubbish on the inflatable sealing strip when empting rubbish, and then is favorable to improving the reliability and the leakproofness of inflatable sealing strip. Because the left, right and lower three edges of the inner wall of the cavity 102 (i.e. the inner side of the cavity 102) are provided with the convex structures 108 along the sealing surface 106, the left, right and lower three edges of the door body 110 are provided with the concave structures 114 towards one side of the discharge port 104, the inflatable sealing strips are arranged at one end of the concave structures 114 close to the discharge port 104, and when the discharge port 104 is closed by the door body 110, as shown in fig. 4, the convex structures 108 are positioned inside the concave structures 114, i.e. the convex structures 108 and the concave structures 114 are mutually matched to form a lap joint structure, so that the material in the cavity 102 cannot directly contact. Because the convex structure 108 protrudes out of the sealing surface 106 along the direction of the discharge port 104 departing from the interior of the cavity 102, the dregs and the construction waste are prevented from being stuck to the sealing surface 106 when the dregs or the construction waste are dumped by the dregs vehicle, and therefore the purposes of protecting the inflatable sealing strip and not scratching the inflatable sealing strip are achieved. Meanwhile, when the door body 110 closes the discharge hole 104 of the cavity 102, the inflatable sealing strip is pressed on the sealing surface 106 of the cavity 102, and the convex structure 108 and the concave structure 114 are overlapped to form an integral sealing structure, so that the sealing performance of the connection between the cavity 102 and the door body 110 is greatly improved, and the environment protection and the product reliability improvement are further facilitated. Further, the gas storage part 202 of the muck truck is a gas storage tank, and a path of gas path can be guided from the gas storage tank of the muck truck to inflate the inflatable sealing strip, so that the structure is simplified, and the cost is reduced.
