[0024] The present application discloses a beach landing rapid walking road paving vehicle, which lands on the beach first and performs one-time road paving, facilitating subsequent military vehicles to land and travel quickly. An embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0025] As shown in Figure 1 , the road paving vehicle comprises a vehicle body 1, a traveling mechanism 2, and a storage bin 3. The tracked traveling mechanism 2 has a plurality of long-toothed plates outside, which are used for rapid landing. The traveling mechanism 2 is arranged on both sides of the bottom of the vehicle body 1. Figure 2 As shown in Figure 3 and Figure 4 , the storage bin 3 is detachably fixed to the top front side of the vehicle body 1. The storage bin 3 has a cavity inside. A push-out device 301 is fixed to the rear bottom of the cavity. As shown in Figure 5 and Figure 6 , a plurality of vertical rollers 303 are uniformly embedded in the inner walls of both sides of the cavity. Each roller 303 can rotate. An opening 301 is arranged on the front side of the cavity. The inner walls of both sides of the opening 301 each have a sliding groove. An arc-shaped wedge block 302 with an outer end face is embedded in each sliding groove. A spring is arranged between the wedge block 302 and the sliding groove. The wedge block 302 moves along the sliding groove under the action of an external force and is completely retracted into the sliding groove. The push-out device 301 comprises a push-out device body, an oil cylinder, and a push plate. The oil cylinder is arranged in the push-out device body, and the front end is detachably fixedly connected with the push plate.

[0026] As shown in Figure 7 and Figure 8 , a plurality of extendable bottom plates 5 are stored in the storage bin. Adjacent bottom plates 5 are connected with each other by ropes. The bottom plates 5 are made of a material with large friction. In this embodiment, the bottom plates 5 are made of rubber material. A plurality of bottom plates 5 in a retracted state are stacked in an S shape in the cavity of the storage bin 3, forming a plurality of vertical arrangements. Except for the first row, the remaining bottom plates are stacked on the top of the push-out device body. The opening 301 is adapted to the bottom plates 5 in the retracted state. The bottom plate 5 at the bottom of the first row corresponds to the opening 301. The push plate can push the bottom plate 5 out of the storage bin 3 from the opening 301 under the action of the oil cylinder.As shown, the bottom plate 5 includes auxiliary plates 501 and elastic members 502, and each side of the bottom plate 5 has a receiving cavity, and the auxiliary plates 501 are movably arranged in the receiving cavities. The elastic members 502 are springs, and the elastic members 502 are arranged between the inner bottom of the receiving cavities and the auxiliary plates 501, and are fixedly connected with the inner bottom of the receiving cavities and the auxiliary plates 501 respectively. Each side of the auxiliary plate 501 has a protruding sliding part 504, and each receiving cavity has a sliding groove 505 corresponding to the sliding part 504 on each side, and the elastic members 502 can push the auxiliary plates 501 to extend out of the receiving cavities along the sliding grooves 505 by using elastic potential energy. Each auxiliary plate 501 has a plurality of toothed holes 503 corresponding to the long-toothed plate of the traveling mechanism 2, the length of each toothed hole 503 is greater than the length of the long-toothed plate, and the width of each toothed hole 503 is greater than the width of the long-toothed plate.

[0027] The front of the vehicle body 1 is provided with a guard plate 4, and the front part of the vehicle body 1 and the guard plate 4 are inclined towards the traveling mechanism 2, and the left and right sides of the guard plate 4 are detachably fixedly connected with the vehicle body 1. The guard plate 4 and the vehicle body 1 form an inclined sliding channel therebetween, and the sliding channel is matched with the bottom plate 5 in the elongated state. The guard plate 4 is made of rigid material, can resist attacks from the front, and greatly improves the anti-external interference ability during landing on the mudflat. The bottom rear side of the vehicle body 1 has an outward arc-shaped protrusion, and the protrusion protrudes from the long-toothed plate of the traveling mechanism, and is used to disengage the bottom plate 5 from the long-toothed plate.

[0028] Before landing, a proper number of bottom plates 5 in the elongated state are pre-stored in the sliding channel, and each bottom plate 5 is connected by a rope, and the wedge-shaped blocks 302 on both sides of the opening 301 block the remaining bottom plates 5 in the storage bin 3, so as to avoid being dragged out of the storage bin 3 under the action of gravity.

[0029] When the road paving vehicle lands, the pushing device 301 pushes the bottom plate 5 adjacent to the opening 301 out of the storage bin 3, the bottom plate 5 slides along the outer end surface of the wedge-shaped block 302 and extrudes the wedge-shaped block 302, so that the wedge-shaped block 302 is completely retracted into the sliding groove. After the bottom plate 5 completely leaves the storage bin 3, the wedge-shaped block 302 is reset under the action of the spring. After the bottom plate 5 leaves the storage bin 3, the elastic member 502 pushes the auxiliary plate 501, so that the auxiliary plate 501 moves out of the containing cavity by using the sliding part 504 along the sliding groove 505. The bottom plate 5 previously reserved in the sliding channel sequentially moves downward along the sliding channel and is in contact with the long-toothed plate in the traveling mechanism 2. The auxiliary plate 501 has a plurality of toothed holes 503, and as the traveling mechanism 2 rotates, the long-toothed plate is in mesh with the auxiliary plate 501. When the long-toothed plate is inserted into the toothed hole 503, the bottom plate 5 in the storage bin 3 can be pulled out along with the rotation of the traveling mechanism 2, and the sidewalls on both sides of the storage bin 3 are embedded with a plurality of rotatable vertical rollers 303, which can be used to reduce the friction between the two sides of the bottom plate 5 and the storage bin 3 when being pulled out, facilitating the rapid pulling out from the storage bin 3 for road paving. The bottom rear side of the vehicle body 1 has a protrusion, which is used for the long-toothed plate to disengage from the bottom plate 5, so as to avoid damage to the bottom plate 5. The traveling mechanism 2 quickly pulls out the bottom plate 5 from the storage bin 3 to form a road, increases the contact area with the mudflat, increases the friction and facilitates the subsequent vehicle landing and walking.

[0030] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present application should also be within the scope of the present application.
