[0022] In order to make the purpose, technical solutions 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 exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0023] Reference Figures 1-6 A muddy road paving vehicle includes a vehicle body 1 and a roller 2. A crawler track 11 is mounted on the bottom of the vehicle body 1, allowing the vehicle body 1 to move along the crawler track 11. The crawler track 11 facilitates movement on muddy roads and prevents the vehicle body 1 from slipping. A rotating platform 12 is mounted at the center of the lower portion of the vehicle body 1. The rotating platform 12 enables the vehicle to return directly to its original route even in narrow spaces where turning around is difficult.

[0024] 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 raising and lowering of the roller 2. The forearm mechanism 3 includes an upper arm 31, a lower arm 32, and a base 33. The base 33 is fixed to 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 with bolts and nuts. When the angle of the support arm 34 needs to be adjusted, the nuts are loosened. After the angle is adjusted, the nuts are tightened to fix the support arm 34 and the base 33.

[0025] One end of the arm 32 is hinged to the top of the support arm 34. A first hydraulic cylinder 35 is hinged to the base 33, and the piston rod of the first hydraulic cylinder 35 is hinged to the arm 32. A receiving slot 321 is defined on the side of the arm 32 near the upper arm 31. The upper arm 31 near the arm 32 is inserted into the receiving slot 321. A sliding adjustment slot 322 is defined on the outer wall of the arm 32. A connecting shaft 312 is fixed to the outer wall of the arm 31, and the connecting shaft 312 can slide in the sliding adjustment slot 322. A second hydraulic cylinder 36 is hinged between the upper arm 31 and the arm 32. The second hydraulic cylinder 36 can drive the upper arm 31 to move forward or backward, causing the connecting shaft 312 on the arm 31 to slide along the sliding adjustment slot 322. The first hydraulic cylinder 35 can drive the arm 32 to rotate, thereby driving the upper arm 31 to rotate, thereby raising or lowering the roller 2.

[0026] A rotary motor 37 is fixed to the side of the boom 31 near the roller 2. A fixing plate 38 is fixed to the output shaft of the rotary motor 37, and the fixing plate 38 is bolted to the roller 2. The outer circumferential wall of the roller 2 is provided with multiple transverse buffer strips 21, which are the same length as the roller 2. Multiple anti-slip pads 22 are fixed to the transverse buffer strips 21. The roller 2 can be replaced with an obstacle shovel 23. In special circumstances, such as for engineering construction tasks such as clearing obstacles, clearing with a shovel, disaster relief, and filling ditches, the roller 2 can be replaced with an obstacle shovel 23, greatly increasing the vehicle's overall usability.

[0027] The paving vehicle body 1 is internally provided with a precast slab recovery mechanism 4, which comprises a drive roller 41 and a belt 42. The drive roller 41 drives the belt 42, which is wrapped around the precast slab. The paving vehicle body 1 is internally provided with a motor that drives the drive roller 41 in forward or reverse rotation. The belt 42 can release and collect the precast slabs.

[0028] The front end of the paving vehicle body 1 is provided with a front notch 15, and the rear end of the paving vehicle body 1 is provided with a rear notch 16. The paving vehicle is equipped with two paving board 8 storage systems. One is a roller 2, which can gather some prefabricated boards in the outer layer. Since the roller 2 is made of a lightweight hollowed-out composite metal structure, its low weight does not affect its temporary transportation and storage function. 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 board 5 can also be directly laid by transferring it from the rear. A leveling roller 17 is installed 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.

[0029] A tailgate 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 tailgate 5 and the rear portion of the paving vehicle body 1. The tailgate 5 and the hinge 52 are hingedly connected. A precast board recovery and cleaning mechanism 6 is provided above the tailgate 5 for vibrating and cleaning the paving boards 8. The precast board recovery and cleaning mechanism 6 includes a waterproof plate 61, which is fixed to the tailgate 5. The waterproof plate 61 is provided with a plurality of support bars 62 arranged along the width direction of the paving vehicle body 1. A plurality of springs 63 are fixed between the support bars 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 tailgate 5 are closed.

[0030] When the paving board 8 is to be recycled, 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.

[0031] A cleaning mechanism 7 is provided at the rear of the paving vehicle body 1. This cleaning mechanism 7 includes a water tank 71 fixed to 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 nozzles 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 an appropriate distance toward the paving board 8, spraying water at the paving board 8 to rinse it.

[0032] The paving vehicle body 1 is equipped with a front camera 13 and a rear camera 14, and the arm 31 is equipped with a laser radar 311. 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.

[0033] The implementation principle of the 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 via 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.

[0034] Another method involves laying the paving slab 8 naturally through the rear notch 16 on the tailgate 5 platform. The forearm mechanism 3 is equipped with an obstacle-clearing shovel 23, making it suitable for environments with numerous obstacles and complex terrain. This method of clearing obstacles in front and paving in the back offers the advantages of integrated obstacle clearing and paving. Once the appropriate paving mode is selected, the road paving operation can begin. Maintain a steady speed during operation, and activate the LiDAR 311 system and visual monitoring system to observe the terrain and surrounding environment.

[0035] This invention addresses the challenges of traditional muddy road paving methods, such as long construction times, high labor and material consumption, and challenges with construction in inclement weather. By adopting a standardized prefabricated panel design, this invention simplifies the road construction process, reduces reliance on human resources, and improves construction speed and safety.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
