Detailed Description of the Preferred Embodiment

[0017] As Figure 1-7As shown: A milling machine includes a forklift frame. The front end of the forklift frame 1 has a working box 3. The front end of the forklift frame 1 is fixedly connected with a forklift arm 2. Socket openings 19 are respectively provided on both side walls of the working box 3. Both ends of a square tube 20 are respectively within the two socket openings 19, and both ends of the square tube 20 are fixedly connected with the two socket openings 19 respectively. The forklift arm 2 is inserted into the square tube 20. The bottom of the working box 3 is open. Both ends at the rear side of the bottom of the working box 3 are fixedly connected with fixed tubes 17. The inner wall of the fixed tube 17 is threadedly connected with an adjusting screw rod 18. The bottom end of the adjusting screw rod 18 is rotatably connected with a supporting wheel 4. A gasoline engine 5 and a blower 6 are fixedly installed on the top of the working box 3. The blower 6 is located at the rear side of the gasoline engine 5. The air outlet of the blower 6 communicates with the inside of the working box 3. A milling wheel 7 is rotatably connected between the left and right inner side walls of the working box 3. The bottom of the milling wheel 7 protrudes from the bottom of the working box 3 and is flush with the bottom of the supporting wheel 4. A first belt pulley 8 is fixedly connected to the left support shaft of the milling wheel 7, the left end of the output shaft of the gasoline engine 5, and the left end of the impeller shaft of the blower 6. The first belt pulley 8 connected to the milling wheel 7 and the first belt pulley 8 connected to the output shaft of the gasoline engine 5 are sleeved with a first belt 9. The first belt pulley 8 connected to the blower 6 and the first belt pulley 8 connected to the output shaft of the gasoline engine 5 are sleeved with a first belt 9; An outlet opening 10 is provided at the top of the front side wall of the working box 3. Fixed plates 12 extending obliquely upward to the front side are fixedly connected to the bottoms of the left and right inner side walls of the outlet opening 10. A roller 13 is rotatably connected between the two ends of the two fixed plates 12. A conveyor belt 14 is sleeved between the outer walls of the two rollers 13. A second belt pulley 15 is fixedly connected to the right support shaft of the milling wheel 7 and the right end of the rear roller 13. A second belt 16 is sleeved between the outer walls of the two second belt pulleys 15.

[0018] A curtain 11 is fixedly connected to the inner top wall of the outlet opening 10, and the bottom of the curtain 11 contacts the top of the conveyor belt 14.

[0019] The forklift frame 1 is a part of an existing forklift, and the existing forklift is a device of the prior art.

[0020] The curtain 11 plays a certain blocking role, preventing the crushed stone powder from directly splashing out of the working area under the action of wind force, and at the same time ensuring that the crushed stone powder can smoothly fall on the conveyor belt 14.

[0021] By rotating the adjusting screw rod 18, the up and down position of the supporting wheel 4 can be adjusted, which is convenient for the user to adjust according to different milling heights.

[0022] The operator starts the gasoline engine 5. The gasoline engine 5 drives the milling wheel 7 to rotate through the first belt 9. At the same time, the blower 6 is also driven to rotate by the first belt 9, preparing to blow the crushed stone powder generated by milling in a specified direction.

[0023] The user drives the forklift to the road surface position to be milled, inserts the forklift arm 2 into the square pipe 20, and the milling wheel 7 starts to rotate driven by the gasoline engine 5. Its bottom contacts the ground for milling operation. The rotation of the milling wheel 7 breaks the ground materials (such as the old asphalt layer, concrete layer, etc.) into gravel powder.

[0024] The wind generated by the fan 6 blows the gravel powder milled out by the milling wheel 7 forward. These powders enter the interior of the working box 3 through the opening at the bottom of the working box 3 and are blown towards the discharge port 10 along with the wind.

[0025] At the discharge port 10, the gravel powder is blocked by the curtain 11 and then falls on the conveyor belt 14 extending obliquely upward to the front side. At this time, since the right support shaft of the milling wheel 7 is connected to the rear roller 13 through the second belt 16, the rotation of the roller 13 drives the conveyor belt 14 to operate, and conveys the gravel powder from the discharge port 10 into the muck truck. The upper part of the conveyor belt 14 is above the muck truck. The muck truck is a prior art device and can load the gravel powder. The present utility model only protects the mechanical part, and the functions realized by the software control part related thereto are not within the protection scope of the present utility model.
