A shovel board 7 is fixedly connected to the end of the hopper 11 away from the cab 12. During the driving process of the machine body 1, the shovel board 7 contacts the ground for paving the mixture, and shovels away the gravel and other debris on the ground in front, so that the ground is relatively flat when paving the mixture. The shovel board 7 is rotatably connected to a flattening roller 71, and the flattening roller 71 keeps rotating under the action of friction, and contacts the ground to flatten the ground.
[0047] Reference Figure 1 and Figure 2The flattening roller 71 is provided with three annular grooves 711 along the axial direction, and a fifth bevel gear 73 fixedly connected to the flattening roller 71 is installed in the annular groove 711. The fifth bevel gear 73 is fixedly connected to the flattening roller 71. When the flattening roller 71 rotates, it drives the fifth bevel gear 73 in the annular groove 711 to rotate. The fifth bevel gear 73 is meshed with a sixth bevel gear 74. The shovel plate 7 is provided with an inclined plate 72. The sixth bevel gear 74 is fixedly connected with an inclined rod 741 rotatably connected to the inclined plate 72. A plurality of cleaning leaves 742 are fixedly connected to one end of the inclined rod 741 away from the sixth bevel gear 74. Then, the sixth bevel gear 74 drives the cleaning leaves 742 on the inclined rod 741 to rotate. When the cleaning leaves 742 rotate, they sweep away the gravel and other debris in front of the shovel plate 7, and sweep the gravel and other debris to both sides of the machine body 1, so as to avoid too much debris on the shovel plate 7.
[0048] Reference Figure 1 and Figure 3 A conveyor belt 111 is installed in the hopper 11, and a motor for driving the belt is installed in the machine body 1. A plurality of parallel conveying rollers are arranged on both sides of the machine body 1 to support the conveyor belt 111 and ensure the conveying function of the conveyor belt 111. When the mixture is spread, the mixture is poured into the hopper 11, and then the mixture falls onto the conveyor belt 111, and the mixture is transported away from the hopper 11 on the conveyor belt 111. A plurality of partitions 112 are fixedly connected to the conveyor belt 111 along the circumferential direction, and the partitions 112 increase the friction between the conveyor belt 111 and the mixture, which can accelerate the conveying speed of the mixture.
[0049] Reference Figure 3 and Figure 4 A positioning plate 121 is fixedly installed on the end of the cab 12 away from the hopper 11, and the positioning plate 121 is fixedly connected to the motor 3. The output shaft of the motor 3 passes through the positioning plate 121 and is connected to the paving assembly 4. The paving assembly 4 includes a third bevel gear 41, two spiral paving rods 42 and two fourth bevel gears 43. The third bevel gear 41 is fixedly connected to the end of the output shaft of the motor 3, and the output end of the motor 3 drives the third bevel gear 41 to rotate.
[0050] Reference Figure 3 and Figure 4 A spiral conveying blade 421 is fixed on the spiral paving rod 42, and the two spiral paving rods 42 are located on the same axis. The two fourth bevel gears 43 are meshed with the third bevel gear 41, and the fourth bevel gear 43 is fixedly connected to the corresponding spiral paving rod 42. Under the meshing action of the third bevel gear 41 and the fourth bevel gear 43, the end of the spiral paving rod 42 away from the fourth bevel gear 43 is rotatably connected to the corresponding baffle 52. The two spiral paving rods 42 rotate, and the directions of the two spiral conveying blades 421 are opposite, and then the two spiral conveying blades 421 rotate in the opposite direction, so that the mixture is spread on both sides of the width direction of the machine body 1, which is more convenient to spread the mixture.
[0051] Reference Figure 4 and Figure 5 The output shaft of the motor 3 is rotatably connected to a protective cover 34. The third bevel gear 41 and the fourth bevel gear 43 are both located in the protective cover 34. The protective cover 34 protects the meshing transmission of the third gear and the fourth gear. The spiral paving rods 42 are rotatably connected to the protective cover 34 to prevent debris from affecting the normal meshing of the third gear and the fourth gear, thereby ensuring the normal paving of the mixture.
[0052] Reference Figure 4 and Figure 5 The end of the cab 12 away from the hopper 11 is fixedly connected with a baffle plate 5, which includes a vertical plate 51 and baffle plates 52 parallel to each other. The baffle plates 52 are fixedly connected to the cab 12, and the vertical plate 51 is located between the two baffle plates 52 and is vertically fixed to the two baffle plates 52. When the mixed material is transported to the baffle plate 5, the material spreading assembly 4 spreads the mixed material under the action of the motor 3, and the baffle plate 5 limits the mixed material to prevent the mixed material from scattering outside the baffle plate 5.
[0053] Reference Figure 5 and Figure 6 The output shaft of the motor 3 is fixedly connected with the first bevel gear 31, and the motor 3 drives the first bevel gear 31 to rotate. The first bevel gear 31 is meshed with the second bevel gear 32, and the second bevel gear 32 is fixedly connected with the transmission rod 33, so that the second bevel gear 32 drives the transmission rod 33 to rotate. The transmission rod 33 passes through the vertical plate 51 and is rotatably connected with the vertical plate 51. The end of the transmission rod 33 away from the second bevel gear 32 is provided with a first worm part 331, and then the transmission rod 33 drives the first worm part 331 to rotate.
[0054] Reference Figure 5 and Figure 6 , vertical plates 53 parallel to the baffle plate 52 are fixedly connected on both sides of the vertical plate 51, and a pressure roller 6 is rotatably connected between the vertical plates 53. The pressure roller 6 is provided with a circular groove 61, and a first worm wheel portion 62 meshing with the first worm portion 331 is installed in the circular groove 61. The first worm wheel portion 62 is fixedly connected to the pressure roller 6, and then the first worm portion 331 and the second worm portion 514 meshing together make the pressure roller 6 between the two vertical plates 53 rotate, and the pressure roller 6 rolls the paved mixture, so that the same construction equipment can complete the paving and rolling of the mixture at the same time, and the operator does not need to drive the paver and the roller to complete the paving and rolling operations separately, thereby improving the paving and rolling efficiency of the mixture. The pressure roller 6 performs the initial compaction on the mixture that has just been paved, and the roller can be used to repeat the compaction in the subsequent sequence.
[0055] Reference Figure 5 and Figure 6The transmission rod 33 is fixedly connected with the first gear 331 near the first worm part 331. When the transmission rod 33 rotates, it drives the first gear 331 to rotate. The vertical plate 51 is rotatably connected with the rotating rod 511. The rotating rod 511 is fixedly connected with the second gear 512 meshing with the first gear 331, so that the second gear 512 drives the rotating rod 511 to rotate. The end of the rotating rod 511 close to the pressure roller 6 is fixedly connected with bristles 513. The bristles 513 on the rotating rod 511 clean the first worm wheel part 62 to prevent the mixture entering the circular groove 61 from being stuck on the first worm wheel part 62, thereby ensuring the normal meshing of the first worm wheel part 331 and the first worm wheel part 62.
[0056] Reference Figure 5 and Figure 6 When the spiral conveying blade 421 spreads the mixture, part of the mixture is easily adhered to the surface. After long-term use, the thickness of the mixture on the spiral conveying blade 421 increases, which is easy to have an adverse effect on the paving efficiency of the mixture. A crossbar 521 is rotatably connected between the baffles 52. The rotating rod 511 passes through the vertical plate 51 and is fixedly connected to the second worm part 514. When the rotating rod 511 rotates, it drives the second worm part 514 to rotate. The crossbar 521 is fixedly connected to the second worm wheel part 522. The second worm wheel part 522 meshes with the second worm wheel part 514, so that the second worm wheel part 522 drives the crossbar 521 to rotate.
[0057] Reference Figure 5 and Figure 6 The cross bar 521 is fixedly connected with a plurality of scrapers 523 along the circumferential direction. The scrapers 523 are in conflict with the spiral conveying blades 421. All scrapers 523 on the cross bar 521 are in conflict with the spiral conveying blades 421 when rotating. The scrapers 523 scrape off the mixture adhered to the spiral conveying blades 421, thereby improving the paving efficiency of the spiral conveying blades 421 on the mixture and achieving a better paving effect on the mixture.
