Detailed Description of the Preferred Embodiments

[0017] Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0018] As Figures 1-4 shown, a simple device for quickly milling asphalt concrete includes a moving body 1. Adjusting cavities 2 are provided on both sides of the bottom of the moving body 1, and moving components are provided inside the adjusting cavities 2.

[0019] In the middle of the bottom of the moving body 1, an assembly cavity 3 is provided. A protective cover 4 is slidably connected inside the assembly cavity 3. Milling rollers 5 are rotatably connected to both sides inside the protective cover 4. A driving member 6 is installed on the top of the protective cover 4. The driving end of the driving member 6 is connected to one end of the milling roller 5 through a synchronous belt and a synchronous pulley to synchronously drive the two milling rollers.

[0020] A hydraulic push rod 7 is installed on the inner wall of the top of the assembly cavity 3, and the output end of the hydraulic push rod 7 is connected to the top of the protective cover 4. A water tank 8 is installed on the top of the moving body 1. One side of the water tank 8 is connected with a delivery pump 9. One side of the delivery pump 9 is connected with a horizontal pipe 10. Both sides of the horizontal pipe 10 are communicated with telescopic hoses 11. Atomizing nozzles 12 are arranged on both sides inside the protective cover 4. One end of each telescopic hose 11 penetrates through the wall surfaces of the moving body 1 and the protective cover 4 and is communicated with the atomizing nozzle 12.

[0021] The moving assembly includes an adjusting frame 13. The adjusting frame 13 is slidably connected to the inner wall of the adjusting cavity 2. Moving wheels 14 are installed on both sides of the bottom of the adjusting frame 13. An adjusting screw rod 15 is threadedly connected to the top of the adjusting frame 13. The top of the adjusting screw rod 15 penetrates through the adjusting cavity 2.

[0022] It should be noted that when milling the asphalt concrete pavement is required, the operator moves the device through the moving wheels 14; due to the different heights of the construction workers, when the operator uses a device that does not match his own height, it will be very uncomfortable. Therefore, the operator can rotate the adjusting screw rod 15 through the handle 16, and cooperate with the moving frame to adjust the height of the moving body 1, thereby increasing the comfort of the operator.

[0023] Since the height of the moving body 1 changes, at this time the hydraulic push rod 7 operates, drives the milling roller 5 to descend through the protective cover 4 and contacts the asphalt concrete pavement. Subsequently, the driving member 6 operates, and through the cooperation of the synchronous pulley and the synchronous belt, the milling roller 5 can be driven to rotate, so as to achieve the purpose of quickly milling the asphalt concrete pavement; at the same time, the protective cover 4 can inhibit the dust generated during the milling process to a certain extent, and during the rapid milling of the asphalt concrete, the delivery pump 9 operates, can draw water from the inside of the water tank 8, and through the transportation of the horizontal pipe 10 and the telescopic hoses 11, and finally sprayed out through the atomizing nozzles 12, further inhibiting the dust generated by milling and ensuring the physical and mental health of the surrounding workers.

[0024] A limiting piece 17 is rotatably connected to the bottom of the assembly cavity 3. The limiting piece 17 is connected to the bottom of the moving body 1 with a fixing bolt. The limiting piece 17 can limit the position of the protective cover 4 to prevent the protective cover 4 from falling off from the inside of the assembly cavity 3 and increase the operating stability of the device. A liquid level gauge 18 is arranged at the front end of the water tank 8 to facilitate observing the liquid level inside the water tank 8.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
