[0007] Furthermore, the arc-shaped protrusion of the shovel plate faces the lower right, and the thickness of the shovel plate gradually becomes thinner from the right end to the left end. The left end of the shovel plate is a blade formed by the top surface and the left end of the bottom surface of the shovel plate overlapping, and baffles are vertically provided at the front and rear ends of the top surface of the shovel plate.

[0008] Furthermore, the left end of the shovel plate and the lower end of the roller are at the same height, and the distance between the left ends of the two baffles is greater than the distance between the two rollers on the same rotating rod.

[0009] Furthermore, a rotating shaft 1 is rotatably connected between the left parts of the front and rear side plates of the box body, and a rotating shaft 2 is rotatably connected to the front and rear side plates of the box body on the upper right side of the rotating shaft 1. A conveyor belt is commonly covered on the outside of the rotating shaft 1 and the rotating shaft 2. A bearing plate is provided inside the conveyor belt and is located between the rotating shaft 1 and the rotating shaft 2.

DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:

[0021] like Figure 1 to Figure 4 As shown, an asphalt paving and leveling device includes a box body 1, a conveyor belt 2, a roller 3 and a shovel 4; the box body 1 is a hollow rectangular parallelepiped, the left end and the upper end of the box body 1 are open, and a conveyor belt 2 with a lower left and a higher right is rotatably arranged in the box body 1, and rod bodies 5 are arranged at intervals on the outer ring surface of the conveyor belt 2 along the annular direction of the conveyor belt 2, and the rod bodies 5 are long strips arranged along the width direction of the conveyor belt 2; two rotating rods 6 located at the same height are arranged in the lower part of the box body 1, and the rotating rods 6 are round rods. The two rotating rods 6 are both located on the right side of the conveyor belt 2, and the two ends of each rotating rod 6 are respectively It penetrates and rotatably connects the front and rear side panels of the box body 1. Both ends of the rotating rod 6 are connected to the roller 3 whose lower end is lower than the box body 1. A rod body 2 7 is arranged on the left rotating rod 6. The rod body 2 7 is a long strip rod arranged along the length direction of the rotating rod 6. The rod body 2 7 on the left rotating rod 6 engages with the rod body 1 5 on the lower side of the outer ring surface of the conveyor belt 2; a partition plate 8 is provided in the box body 1 on the upper side of the two rotating rods 6; the shovel plate 4 is an isosceles trapezoidal plate that is lower on the left and higher on the right. The left end of the shovel plate 4 is wide and the right end is narrow. The front and back right parts of the shovel plate 4 are connected to the front and rear side panels of the box body 1, and the right end of the shovel plate 4 extends into the box body 1 and is located on the upper side of the left end of the conveyor belt 2.

[0022] The arc-shaped protrusion of the shovel plate 4 faces the lower right, and the thickness of the shovel plate 4 gradually becomes thinner from the right end to the left end. The left end of the shovel plate 4 is a blade formed by the top surface and the left end of the bottom surface of the shovel plate 4 overlapping. The front and rear ends of the top surface of the shovel plate 4 are vertically provided with baffles 9.

[0023] The left end of the shovel plate 4 and the lower end of the roller 3 are at the same height, and the distance between the left ends of the two baffles 9 is greater than the distance between the two rollers 3 on the same rotating rod 6. The purpose is that the baffle 9 can ensure that the asphalt scraped by the shovel plate 4 will not fall through the front and rear ends of the shovel plate 4, and can ensure that the roller 3 rolls on a flat road surface after the shovel plate 4 scrapes the asphalt.

[0024] A rotating shaft 10 is rotatably connected between the left parts of the front and rear side plates of the box body 1, and a rotating shaft 2 11 is rotatably connected to the front and rear side plates of the box body 1 on the upper right side of the rotating shaft 10. The rotating shaft 10 and the rotating shaft 2 11 are round rods with the same diameter. The rotating shaft 10 and the rotating shaft 2 11 are commonly covered with a conveyor belt 2. A bearing plate 12 is provided inside the conveyor belt 2 and is located between the rotating shaft 10 and the rotating shaft 2 11. The front and rear ends of the bearing plate 12 are fixedly connected to the front and rear inner surfaces of the box body 1, and the inner surface of the conveyor belt 2 slides in contact with the bearing plate 12.

[0025] The conveyor belt 2 is an annular belt body made of polyester fiber material. The conveyor belt 2 made of polyester fiber material is not easy to adhere to asphalt. The front and rear ends of the conveyor belt 2 slide in contact with the front and rear inner surfaces of the box body 1.

[0026] The partition 8 is a rectangular plate that is higher on the left and lower on the right, and the front and rear ends are fixedly connected to the front and rear inner surfaces of the box body 1. The left end of the partition 8 is lower than the right end of the conveyor belt 2 and close to the conveyor belt 2. The left end of the partition 8 is provided with a wire brush 13 whose end contacts the lower side of the outer ring surface of the conveyor belt 2. The right end of the partition is connected to the right side plate of the box body. The right side plate of the box body 1 is provided with a box door 14 that is higher than the right end of the partition 8. The box door 14 can be opened or closed, and a handle 15 is provided on the outer side of the right side plate of the box body 1 above the box door 14.

[0027] When in use, close the box door 14, use the handle 15 to push the box body 1 forward, and when the box body 1 moves forward, each roller 3 drives the connected rotating rod 6 to rotate counterclockwise (the counterclockwise rotation of the roller 3 and the rotating rod 6 is Figure 2 As seen from the perspective in the figure, the shovel plate 4 shovels the asphalt to be leveled as the box body 1 moves, and the shoveled asphalt moves to the right along the top surface of the shovel plate 4 until it falls onto the conveyor belt 2; when the left rotating rod 6 rotates counterclockwise, the rod body 2 7 on the left rotating rod 6 engages with the rod body 1 on the lower side of the conveyor belt 2, driving the conveyor belt 2 to rotate clockwise (the clockwise rotation of the conveyor belt 2 is Figure 2 The asphalt on the outer ring surface of the conveyor belt 2 is dropped to the upper side of the outer ring surface of the conveyor belt 2 through the right end of the shovel plate 4. During the clockwise rotation of the conveyor belt 2, the plurality of rod bodies 5 rotate along with the conveyor belt 2. The rod body 5 on the upper side of the conveyor belt 2 drives the asphalt on the conveyor belt 2 to move to the right, until the asphalt on the conveyor belt 2 drops onto the partition 8 through the right end of the conveyor belt 2. A wire brush 13 is provided at the left end of the partition 8 to clean the asphalt embedded between two adjacent rod bodies 5.

[0028] After the asphalt in the box 1 on the upper side of the partition 8 is collected for a period of time, the utility model is pushed to the potholes in the asphalt road surface where asphalt needs to be replenished, and the box door 14 is opened. Since the partition 8 is higher on the left and lower on the right, it has a guiding effect. Under the guidance of the partition 8, the asphalt slides to the potholes in the road surface, making it convenient to spread the potholes in the asphalt road surface flat.

[0029] The preferred implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings; however, the present invention is not limited to the above-mentioned embodiments. Without violating the spirit of the present invention, i.e., the disclosure scope, any equivalent or equivalent deformation or replacement of the technical solution of the present invention shall fall within the protection scope of the present invention.
