[0014] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0015] Reference Figure 1-Figure 6 A muddy road paving vehicle includes a paving vehicle body 1 and a roller 2. A crawler 11 is installed at the bottom of the paving vehicle body 1. The paving vehicle body 1 moves on the crawler 11. The crawler 11 facilitates walking on muddy roads and prevents the paving vehicle body 1 from slipping. A rotating platform 12 is installed at the center of the lower part of the paving vehicle body 1. The rotating platform 12 can enable the paving vehicle to return directly along the original route in a narrow space where it is not easy to turn around.

[0016] A forearm mechanism 3 is provided on one side of the paving vehicle body 1, and a forearm mechanism 3 is provided on both sides of the roller 2. The two forearm mechanisms 3 can control the lifting and lowering of the roller 2. The forearm mechanism 3 includes a large arm 31, a small arm 32 and a base 33. The base 33 is fixed on the paving vehicle body 1. A support arm 34 is rotatably connected to the base 33. The support arm 34 and the base 33 are fixed by bolts and nuts. When the angle of the support arm 34 needs to be adjusted, the nut is loosened. After the angle is adjusted, the reinforcing nut is tightened to fix the support arm 34 and the base 33.

[0017] One end of the small arm 32 is hinged to the top of the support arm 34, and a first hydraulic cylinder 35 is hinged on the base 33, and the piston rod of the first hydraulic cylinder 35 is hinged to the small arm 32. A receiving groove 321 is provided on the side of the small arm 32 close to the upper arm 31, and the side of the upper arm 31 close to the small arm 32 is inserted into the receiving groove 321. A sliding adjustment groove 322 is provided on the outer wall of the small arm 32, and a connecting shaft 312 is fixed on the outer wall of the upper arm 31. The connecting shaft 312 can slide in the sliding adjustment groove 322. A second hydraulic cylinder 36 is hinged between the upper arm 31 and the small arm 32. The second hydraulic cylinder 36 can drive the upper arm 31 to move forward or backward, so that the connecting shaft 312 on the upper arm 31 slides along the sliding adjustment groove 322. The first hydraulic cylinder 35 can drive the small arm 32 to rotate, thereby driving the upper arm 31 to rotate, so that the roller 2 is lifted or lowered.

[0018] A rotating motor 37 is fixed to the side of the arm 31 close to the roller 2, and a fixing plate 38 is fixed to the output shaft of the rotating motor 37, and the fixing plate 38 is fixed to the roller 2 by bolts. A plurality of transverse buffer strips 21 are arranged on the outer circumferential wall of the roller 2, and the length of the transverse buffer strips 21 is the same as that of the roller 2. A plurality of anti-skid pads 22 are fixed on the transverse buffer strips 21. The roller 2 can be replaced with an obstacle-breaking shovel 23. In special circumstances, such as obstacle-breaking, shoveling, disaster relief, and filling ditches, the roller 2 can be replaced with an obstacle-breaking shovel 23, which greatly increases the comprehensive use conditions of the vehicle.

[0019] The paving vehicle body 1 is provided with a prefabricated board recovery mechanism 4, which includes a driving roller 41 and a belt 42. The driving roller 41 drives the belt 42 to rotate, and the belt 42 is wrapped around the prefabricated board. The paving vehicle body 1 is provided with a motor that drives the driving roller 41 to rotate forward or reverse. The belt 42 can place and collect the prefabricated board.

[0020] A front notch 15 is provided at the front end of the paving vehicle body 1, and a rear notch 16 is provided at the rear end of the paving vehicle body 1. The paving vehicle is provided with two paving board 8 storage systems, one of which is a roller 2. The roller 2 can gather part of the prefabricated boards in the outer layer. Since the roller 2 is made of a light hollowed-out composite metal structure, the weight is relatively low and the temporary transportation and storage functions are not affected; the other is a prefabricated board recovery mechanism 4. After the prefabricated boards on the roller 2 are exhausted, the prefabricated boards can be transferred from the front notch 15 to the roller 2 laying device for continued laying. The tail plate 5 can also be directly laid by transferring from the rear. A leveling roller 17 is rotatably provided in the paving vehicle body 1. The leveling roller 17 is located between the front notch 15 and the belt 42. The leveling roller 17 guides the paving boards 8.

[0021] A tail plate 5 is provided on the side of the paving vehicle body 1 away from the forearm mechanism 3. A hinge 52 is installed between the tail plate 5 and the rear of the paving vehicle body 1. The tail plate 5 is hingedly connected to the hinge 52. A prefabricated board recovery and cleaning mechanism 6 for vibrating and cleaning the paving board 8 is provided above the tail plate 5. The prefabricated board recovery and cleaning mechanism 6 includes a waterproof plate 61, which is fixed on the tail plate 5. A plurality of support bars 62 are provided on the waterproof plate 61 along the width direction of the paving vehicle body 1. A plurality of springs 63 are fixed between the support bar 62 and the waterproof plate 61. A third hydraulic cylinder 51 is installed between the waterproof plate 61 and the paving vehicle. When the third hydraulic cylinder 51 contracts, the waterproof plate 61 and the tail plate 5 are closed.

[0022] When the paving board 8 is to be recovered, the belt 42 rotates, and the paving board 8 passes through the rear notch 16 and enters the interior of the paving vehicle body 1. Before entering the interior of the paving vehicle, the paving board 8 passes through the support bar 62. The support bar 62 swings up and down under the action of the spring 63, causing the paving board 8 to vibrate, thereby causing the attachments adhered to the paving board 8 to fall off.

[0023] A cleaning mechanism 7 is provided at the rear of the paving vehicle body 1. The cleaning mechanism 7 includes a water tank 71 fixed on the top of the paving vehicle body 1. High-pressure nozzles 72 are installed at the top and bottom of the rear notch 16. A water pipe is connected between the high-pressure nozzle 72 and the water tank 71, and a pressure pump is installed on the water pipe. The paving board 8 passes between the two high-pressure nozzles 72. The high-pressure nozzles 72 can be raised and lowered. When the paving board 8 is recovered, the high-pressure nozzles 72 move a proper distance toward the direction close to the paving board 8, and the high-pressure nozzles 72 spray water at the paving board 8 to wash the paving board 8.

[0024] A front camera 13 and a rear camera 14 are installed on the paving vehicle body 1, and a laser radar 311 is installed on the arm 31. During the paving operation, the vehicle maintains a constant speed. During the operation, the laser radar 311 system and the visual monitoring system are turned on to observe the terrain and surrounding conditions.

[0025] The implementation principle of a muddy road fast paving vehicle of the present invention is: when the paving vehicle is paving the road, the paving vehicle body 1 is moved to the starting point, the roller 2 is adjusted to an appropriate height, and the paving work is started. There are two paving modes for laying the paving board 8. One is that the paving board 8 passes through the front notch 15 in front of the paving vehicle and is connected to the roller 2 for compaction and paving. It is suitable for conventional muddy roads and has the advantages of one-time paving, compaction and adjustable angle.

[0026] The other is that the paving board 8 is naturally laid from the rear notch 16 through the tail plate 5 platform, and the obstacle removal shovel 23 is installed on the forearm mechanism 3, which is suitable for environments with many obstacles and complex terrain. The obstacle removal in front and paving in the back have the advantages of integrated construction of obstacle removal and paving. After selecting the corresponding scene paving mode, the road paving operation can be started, and the driving speed is maintained. During the operation, the laser radar 311 system and the visual monitoring system are turned on to observe the terrain and the surrounding environment.

[0027] The present invention solves the problems existing in the traditional muddy road paving method, such as long construction time, large consumption of manpower and material resources, and construction difficulties in bad weather. By adopting a standardized prefabricated panel design, the present invention simplifies the road construction process, reduces dependence on human resources, and improves construction speed and safety.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention are included in the protection scope of the present invention.
