Description

Technical Field

[0001] The invention relates to the technical field of road construction, in particular to a cutting device for asphalt concrete road construction. Background Art

[0002] According to the patent document with the publication number CN 214831774 U, the rotation angle of the support plate can be adjusted by adjusting the component when in use, so as to control the cutting wheel to contact the ground or to be away from the ground. At this time, when the support plate rotates toward the side close to the ground, the support plate contacts the shock-absorbing seat, and the shock-absorbing seat and the shock-absorbing pad on the base can buffer the vibration of the support plate. Then, the cutting wheel is sprayed with water to cool it down and reduce dust dispersion through the water spray component.

[0003] In the patent document, when the cutting wheel is cooled and dissipated by spraying water, the dust will follow the water flow to other locations on the road surface. As the water evaporates, the dust will gradually dry up, and the dry dust will fly again to other places as the vehicle moves, thereby affecting the surrounding environment. At the same time, very loud noise will be generated during the cutting process of the cutting wheel, which will then cause the surrounding to be disturbed by the noise. Summary of the invention

[0035] In this embodiment: the cutting mechanism 2 includes a rotating shaft 21, two cutting blades 22 are fixed on the outside of the rotating shaft 21, a sealing ring 23 for preventing the coolant from flowing out is arranged between the two cutting blades 22, three guide holes 26 corresponding to each other are opened on the two cutting blades 22, and heat pipes 24 corresponding to the guide holes 26 are arranged on both sides of the two cutting blades 22, and an impeller 25 is fixed on one end of the heat pipe 24 away from the cutting blade 22. The two cutting blades 22 and the sealing ring 23 form an annular cooling chamber, and the rotating shaft 21 is provided with three guide slots 28 at the cooling chamber position, and the heat pipe 24 is a hollow structure, and multiple heat pipes 24 are fixed on the outside of the three heat pipes 24. Annular heat dissipation fins, a guide tube 27 for guiding the coolant to the guide slot 28 is fixed on the inner side of the three heat dissipation tubes 24, and the engine 3 is used to drive the two cutting blades 22 to rotate through the rotating shaft 21 to cut the ground. At the same time, the coolant in the cooling chamber is used to cool the two cutting blades 22. At the same time, the guide holes 26, the guide tube 27 and the guide slot 28 on the rotating shaft 21 on the cutting blades 22 are used to guide the heated coolant into the three heat dissipation tubes 24, and the annular heat dissipation fins on the three heat dissipation tubes 24 are used to cool the heated coolant. At the same time, the rotation of the impeller 25 is used to accelerate the air flow at the annular heat dissipation fins.

[0036] In this embodiment: the dust collecting mechanism 1 includes a protective cover 11, and cylinders for air flow are provided on both sides of the protective cover 11. The two ends of the rotating shaft 21 are rotatably connected to the ends of the cylinders. The cylinder of the protective cover 11 close to the engine 3 is fixedly connected to one side of the lifting bracket 7. A soundproof cover 13 is fixed to the lower side of the protective cover 11. The soundproof cover 13 adopts a rectangular corrugated pipe. The front and rear ends of the soundproof cover 13 are fixed with limit strips 12. The upper ends of the two limit strips 12 are slidably connected to the limit frames 14. The two limit frames 14 are fixedly connected to the front and rear sides of the protective cover 11. The protective cover 1 A dust box 16 is fixed on the upper side, and a dust filter 17 is provided on the top of the dust box 16 for filtering dust when the air flows out. Both sides of the dust box 16 are provided with air guide pipes 15 for connecting the two cylinders therewith. The air is blown into the cylinder of the protective cover 11 by the rotation of the impeller 25. The dust generated during cutting is sent into the dust box 16 through the cylinder of the protective cover 11 and the air guide pipe 15 through the flow of air. At this time, the air entering the dust box 16 is sent out by the dust filter 17. In this process, the dust in the air is filtered by the dust filter 17.

[0037] Working principle: When in use, first push the handrail to allow the mobile vehicle 5 to move the entire device to the position where the road surface needs to be cut under the support of the universal wheel 6. At this time, the telescopic parts of the four electric telescopic rods 4 push the lifting bracket 7 to move downward along the guide strip on the tapered side plate, and the movement of the lifting bracket 7 drives the protective cover 11 and the engine 3 to move downward synchronously. In this process, the engine 3 drives the two cutting blades 22 in the protective cover 11 to rotate at high speed through the rotating shaft 21, and the two heat dissipation pipes 24 and the impeller 25 to rotate synchronously through the high-speed rotation of the cutting blades 22. The rotation of the impeller 25 blows the air in the protective cover 11 into the cylinder. At this time, the air in the cylinder will enter the dust box 16 along the air guide pipe 15, and be sent to the outside from the upper end of the dust box 16;

[0038] As the protective cover 11 moves downward, the lower end of the soundproof cover 13 is pressed against the ground to close the cutting position, and then as the cutting mechanism 2 is lowered as a whole, the two cutting blades 22 are pressed against the ground, and the ground is cut by the high-speed rotating cutting blades 22. The dust generated by the cutting is blown into the cylinder of the protective cover 11 by the rotation of the impeller 25, and enters the dust collecting box 16 with the flow of air. At this time, the dust is filtered by the dust filter cotton 17 during the outflow of air.

[0039] During the cutting process of the cutting blades 22, the two cutting blades 22 are heated and transfer the heat to the coolant in the cooling chamber, and the coolant absorbs the heat and cools the cutting blades 22. The heated coolant passes through the guide holes 26 on the cutting blades 22, the guide tubes 27 and the guide slots 28 on the rotating shaft 21 into the three heat pipes 24, and the annular heat dissipation fins on the three heat pipes 24 cool the heated coolant, thereby accelerating the cooling process of the cutting blades 22.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, and these changes and improvements all fall within the scope of the present invention to be protected.
