Problems solved by technology

[0002] In the existing subgrade improvement and filling construction, the following method is usually adopted for controlling the amount of ash: use a tape measure to measure the length and width of the grid, and mark it well, then pull the wire and use cement and lime to make the grid, Cement and lime are placed in the grid to accurately control the amount of cement and lime, and the excavator is used to mix cement and lime, and then pave manually. Paving is time-consuming and labor-intensive. Therefore, it is urgent to invent a paving machine for accurately controlling the amount of ash mixed in the modified roadbed.

Embodiment 1

[0027] In this embodiment, according to the area of ​​each square grid on the surface of the roadbed is 30 square meters, the following calculation formula is used:

[0028] m h The mass of cement and lime added to each grid; m t is the quality of the soil in the grid; a is the length of the grid; a is the length of the grid; h is the thickness of the loose pavement for subgrade filling, the amount of cement and lime is precisely controlled, and the cement and lime are input into The present embodiment provides a paving machine for accurately controlling the amount of ash added to the modified roadbed.

[0029] refer to Figure 1-4 , the present invention provides a paving machine for accurately controlling the amount of ash mixed in the modified roadbed, including:

[0030] The drive mechanism, the drive mechanism includes a crawler vehicle chassis 1, a drive control chamber 2 is installed on the crawler vehicle chassis 1, the crawler vehicle chassis 1 is a hydraulic mot...

Embodiment 2

[0044] refer to Figure 5 The difference between this embodiment and the first embodiment is that several bases 34 are affixed to the bottom wall of the blanking plate 9, electric slide rails 35 are affixed to the base 34, and two slide rails 35 of the electric slide rails The air duct 36 is fixed between the ends, and the bottom of the air duct 36 is facing the electric valve 21. On the guide rail of the electric slide rail 35 close to the side wall of the mixing box 4, a through groove is opened along the length direction of the electric slide rail 35 and runs through the guide rail. , and offer several through holes on the side wall of the mixing box 4, install the air pump 38 in the through hole, communicate with a flexible hose 37 of suitable length at the top mouth of the air duct 36, the flexible hose 37 passes through the through groove and the air pump 38 connected, reciprocating on the electric slide rail 35 through the air pipe 36, and the wind is generated by the a...
