The top of the balance beam 41 is fixedly connected with A second connecting plate 47 is fixedly connected to the top of the second connecting plate 47 with two telescopic cylinders 48, and the tops of the two telescopic cylinders 48 are fixedly connected to a third connecting plate 49, and one end of the two third connecting plates 49 is respectively fixedly connected to one end of the conveying device 2, a second motor 40 is fixedly installed at one end of the balance beam 41, and one end of the auger 42 is fixedly connected to the output end of the second motor 40, and a third motor 50 is fixedly installed at one end of the support plate 43, and the output end of the third motor 50 is fixedly connected to one end of the transmission shaft 44. By starting the two first motors 34, the two upper hoppers 3 2 rotates and tilts synchronously, so that the asphalt in the two upper hoppers 32 slides to the conveyor belt 21 under the influence of gravity, and is then transported to the paving device 4 through the conveying device 2 to achieve the purpose of timely material replenishment. The auger 42 in the paving device 4 evenly stirs the fallen asphalt under the output of the second motor 40, and the transmission plates 46 at the two eccentric positions drive the ironing plate 45 to move up and down on the inner wall below the support plate 43 under the output of the third motor 50. The auger 42 and the ironing plate 45 work together to achieve the purpose of stirring and ironing the asphalt.

[0020] The mobile mechanism 1 includes four pulleys 11, and one end of the two pulleys 11 on the same vertical horizontal side are commonly fixedly connected with a connecting shaft 12, the outer surface of one connecting shaft 12 is fixedly provided with a transmission component 13, and the top of the transmission component 13 is fixedly connected with a top plate 14, and one end of the top plate 14 is slidably sleeved with the outer surface of the other connecting shaft 12, and the outer surfaces of the two pulleys 11 on the same horizontal horizontal side are commonly sleeved with a crawler 16, and one side of the bottom end of the top plate 14 is fixedly connected with a first connecting plate 15, and the two ends of the first connecting plate 15 are respectively rotatably connected to one end of the balance beam 41, and the transmission component 13 is started to rotate one connecting shaft 12 on one side, so that it can perform synchronous rotation under the drive of the two crawlers 16, so that it can better contact with the bottom surface over a larger area during paving operations, can provide good traction to prevent slipping, and is more suitable for a variety of terrains and road conditions.

[0021] The conveying device 2 includes a conveying body 20, and a conveying belt 21 is rotatably provided inside the conveying body 20. A cover plate 22 is fixedly connected to the top of the conveying body 20, and the bottom end of the conveying body 20 is fixedly connected to the top of the top plate 14. The length of the conveying device 2 is greater than the length of the moving mechanism 1, and one end of the conveying device 2 is located on the upper part of the auger 42. The multiple anti-skid grooves on the surface of the conveying belt 21 prevent the asphalt from getting stuck, and the cover plate 22 prevents the asphalt from overflowing during the conveying process. During the conveying process, the asphalt is continuously moved to the paving device 4 through the conveyor belt 21. When the asphalt moves to the outlet, it descends to the inside of the paving device 4 due to gravity, thereby completing the conveying process.

[0022] The transmission assembly 13 includes a first bevel gear 17, the inner surface of the first bevel gear 17 is fixedly sleeved with the outer surface of the connecting shaft 12, a fourth motor 18 is fixedly installed at one end of the transmission assembly 13, one end of the fourth motor 18 passes through the transmission assembly 13 and is fixedly connected with the second bevel gear 19, the outer surface of the first bevel gear 17 is meshed with the outer surface of the second bevel gear 19, by starting the fourth motor 18, the second bevel gear 19 is driven to rotate under the output of the fourth motor 18, and the rotating second bevel gear 19 drives the connecting shaft 12 to rotate through the first bevel gear 17, thereby realizing the transmission of the two pulleys 11 on one side, providing the same transmission power for the two crawlers 16.

[0023] Both upper hoppers 32 are in an "L" shape. The two upper hoppers 32 are located above the conveying device 2, and the two upper hoppers 32 are distributed in a mirror image. The two "L"-shaped upper hoppers 32 are convenient for loading asphalt. Under the synchronous output of the two first motors 34, the asphalt in the two upper hoppers 32 is rotated and dumped to one side of the conveyor belt 21, which plays a role of synchronous material replenishment.

[0024] The transmission shaft 44 is located at the eccentric top end of the two transmission plates 46, and the outer surface of the ironing plate 45 is slidingly fitted with the lower inner wall of the support plate 43. Under the force of eccentric movement, the two transmission plates 46 located at the eccentric position move vertically up and down through the restriction of the lower inner wall of the support plate 43, which provides feasibility for ironing movement.

[0025] Working principle: When it is necessary to spread asphalt, put the asphalt between the two upper hoppers 32, and move it backwards in a straight line through the moving mechanism 1. The transmission component 13 in the moving mechanism 1 drives the first bevel gear 17 to rotate under the transmission of the second bevel gear 19 through the output of the fourth motor 18, thereby driving one of the connecting shafts 12 to rotate, thereby driving the pulleys 11 at both ends of the connecting shaft 12 to rotate, so that the four pulleys 11 rotate and move on the road surface. The paving operation provides the power for moving backward, and then the conveying device 2 is started. The conveyor belt 21 in the conveying device 2 drives the asphalt to be transported and moved to the paving device 4, and the asphalt is moved through the cover plate 2. The bottom end of the asphalt 2 finally falls into the paving device 4 due to gravity, and the second motor 40 and the third motor 50 in the paving device 4 are started, so that the output end of the second motor 40 drives the auger 42 to rotate, and the rotating auger 42 evenly stirs the descending asphalt material, so that the asphalt material is spread on the road surface more evenly, and the output end of the third motor 50 drives the transmission shaft 44 to rotate, so that the transmission plates 46 at the two eccentric positions move vertically up and down on the lower inner wall of the support plate 43, and the ironing plate 45 at the front end continuously hits the spread asphalt material up and down, flattens, tamps and irons the asphalt material, thereby completing the purpose of asphalt paving;

[0026] When it is necessary to add material and adjust the paving height, the two first motors 34 are started, and the output ends of the two first motors 34 are started to drive the two rotating shafts 33 to rotate, thereby driving the two upper hoppers 32 to rotate. The asphalt material in the upper hopper 32 is continuously rotating and tilting. The asphalt material under the influence of gravity continuously falls toward the conveyor belt 21, thereby completing the purpose of adding material. The two telescopic cylinders 48 are started, and the two telescopic cylinders 48 drive the second connecting plate 47 and the balance beam 41 to move up and down through telescoping. One end of the balance beam 41 is rotatably connected to the two ends of the first connecting plate 15 to provide mobile support, thereby adjusting the paving height of the entire paving device 4.

[0027] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
