The three sets of mixing assemblies 4 facilitate efficient and uniform mixing of several types of crushed stone and stone chips with different particle sizes and gap filler materials put into the storage box 2 to produce graded crushed stone for road granular base paving.

[0032] Reference Figure 1 , Figure 2 and Figure 3 The bottom of the main body 1 of the device is provided with a feeding mechanism 5 for spreading graded crushed stone. The feeding mechanism 5 includes a first mounting frame 51, which is fixedly connected to the right side of the front and back of the main body 1. A material box 52 is fixedly connected to the inner side of the first mounting frame 51.

The material inside the storage box 2 is smoothly output into the material box 52 through the three feed pipes 53. A spreading bucket 54 is connected to the bottom of the material box 52. Vibration motors 55 are fixedly connected to the front and rear ends of the right side of the material box 52. The material box 52 has multiple spreading buckets 54, which work with the vibration motors 55 to spread graded crushed stone for road paving evenly and efficiently. The outer side of the first mounting frame 51 is rotatably connected with a moving wheel 56 for easy movement.

[0033] Reference Figure 1 , Figure 2 and Figure 4The bottom of the main body 1 is provided with a paving mechanism 6 for leveling and spreading materials. The paving mechanism 6 includes a second mounting frame 61, which is fixedly connected to the center of the front and back of the main body 1. The inner wall of the second mounting frame 61 is provided with a guide groove 62. An electric lifting rod 63 is fixedly connected to the top of the inner side of the second mounting frame 61. A paving scraper 64 is fixedly connected to the bottom of the electric lifting rod 63. Slider blocks 65 are fixedly connected to both sides of the paving scraper 64. The sliders 65 are slidably connected to the inside of the guide groove 62. The electric lifting rod 63 controls the paving scraper 64 to rise and fall smoothly along the direction of the guide groove 62, adjusting the height of the bottom of the paving scraper 64 from the ground to level the paving materials. This is suitable for different paving thickness requirements of the road base. A horizontal angle sensor 66 is fixedly connected to the right side of the paving scraper 64. Three horizontal angle sensors 66 are evenly distributed.

The compaction roller 72 is driven by the drive motor 73 to slowly compact the paved material, vibrating all the gap filler into the pores between the coarse gravel, ensuring the flatness of the road base layer.

[0035] Working principle: During use, several types of crushed stone and stone chips of different particle sizes, as well as gap filler, are fed into the storage tank 2 through the feeding hopper 3. The mixing shaft 43 with mixing blades 44 is driven by the mixing motor 41 to mix and blend the materials to produce graded crushed stone for road paving base course. Continuous mixing ensures uniform feeding of the mixed graded crushed stone. The material inside the storage tank 2 is smoothly discharged into the spreading box 52 through three feed pipes 53. Driven by the vibration motor 55 on the spreading box 52, the material is fed into the spreading box 52 by multiple spreading buckets 54. The graded crushed stone used for road paving is evenly spread, and the paving scraper 64 is driven by the electric lifting rod 63 to adjust its height along the guide groove 62. At the same time, the horizontal angle sensor 66 detects the horizontality of the paving scraper 64, thereby changing the height of the bottom of the paving scraper 64 from the ground to the required thickness of the road base layer, and smoothing the spread material. Then, the drive motor 73 drives the roller 72 to slowly compact the spread material, vibrating all the gap filler into the pores between the coarse crushed stone, thus completing the smoothing of the road base layer.
