For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0019] As shown in the attached drawings, the present utility model includes a material leveling assembly 2 and a belt conveyor 3 located below the material leveling assembly 2. The material leveling assembly 2 includes a material leveling box body 4, a material leveling roller 5, and a flattening roller 6. The material leveling roller 5 and the flattening roller 6 are rotatably installed in the material leveling box body 4 in sequence from front to back. A sealing cover 7 communicating with the material leveling box body 4 is provided on the belt conveyor 3.

[0020] The feeding end of the belt conveyor 3 is located inside the material leveling box body 4. Soil falls from the material leveling box body 4 onto the belt conveyor 3 and moves towards one end along with the belt conveyor 3. The soil falls on the belt conveyor 3 in an irregular pile. When passing through the material leveling roller 5, the material leveling roller 5 spreads the irregular soil pile evenly, and then the flattening roller 6 flattens the surface of the soil to prevent the floating soil layer on the surface from rolling and falling during the moving process. The sealing cover 7 seals the conveyor to prevent the odor or gas of pollutants from escaping into the working environment during the conveying process.

[0021] Furthermore, a trapezoidal conveying channel 8 with a wide feeding port and a narrow discharging port is provided inside the material leveling box body 4. A feeding hopper 9 is provided on the material leveling box body 4 at one end of the feeding port of the trapezoidal conveying channel 8. Both the material leveling roller 5 and the flattening roller 6 are located at one end of the discharging port of the trapezoidal conveying channel 8.

[0022] The bottom of the trapezoidal conveying channel 8 is open. During the process of the soil moving along with the belt conveyor 3, the trapezoidal conveying channel 8 serves to gather the soil on the belt conveyor 3 towards the middle. In this case, the width of the feeding port of the trapezoidal conveying channel 8 is smaller than the width of the belt conveyor 3.

[0023] After the soil is first gathered through the trapezoidal conveying channel 8, the material leveling roller 5 then spreads the soil pile, and then the flattening roller 6 flattens the floating soil layer on the surface of the spread soil.

[0024] Preferably, the height of the flattening roller 6 is lower than the height of the material leveling roller 5, which is convenient for the flattening roller 6 to flatten the floating soil layer on the surface during the movement of the soil. Moreover, the rotation directions of the material leveling roller 5 and the flattening roller 6 are opposite. In this case, the material leveling roller 5 rotates clockwise and the flattening roller 6 rotates counterclockwise.

[0025] Furthermore, a motor for driving the material leveling roller 5 and the flattening roller 6 to rotate is provided on the material leveling box body 4. The material leveling roller 5 and the flattening roller 6 are driven by gears, and the rotation speed of the material leveling roller 5 is greater than that of the flattening roller 6.

[0026] The material leveling roller 5 and the flattening roller 6 are driven by a set of variable-speed gears. The material leveling roller 5 rotates quickly to break up and spread the soil pile flat. The rotation speed of the flattening roller 6 is the same as that of the belt conveyor 3. The belt conveyor 3 moves the soil to the right, and the flattening roller 6 rotates counterclockwise to flatten the soil.

[0027] Preferably, both the material leveling roller 5 and the flattening roller 6 are of the Laval tube structure with a thinner middle and thicker ends. A set of raised material leveling teeth 10 are provided on the roller surface of the material leveling roller 5.

[0028] After the Laval tube breaks up and flattens the soil, the soil on the belt conveyor 3 moves in a shape with a thicker middle and thinner sides, effectively preventing the soil from slipping off both sides. The material leveling teeth 10 facilitate the material leveling roller 5 to quickly break up and spread the soil pile flat. The height of the material leveling teeth 10 is 50 mm, and the distance between adjacent teeth in each material leveling tooth 10 is 150 - 200 mm. Adjacent material leveling teeth 10 are staggered from each other.

[0029] Preferably, the sealing cover 7 includes a cover support frame 12. A top plate 13 is provided at the top of the cover support frame 12. A set of side covers 14 and drawers 15 are provided on both sides of the cover support frame 12. One end of the drawer 15 extends under the belt conveyor 3.

[0030] The side cover 14 is hinged to the cover support frame 12 by a pin shaft. A sealing strip that fits the cover support frame 12 is provided at the bottom of the side cover 14. The side cover 14 can be made of a transparent material, which is convenient for observing the internal conveying situation and whether the drawer 15 has collected the fallen soil. When the drawer 15 has collected enough soil, open the corresponding side cover 14 and pour the soil in the drawer 15 onto the belt conveyor 3.
