Description

Technical Field

[0001] The utility model relates to the technical field of milling machines, in particular to an asphalt road marking milling machine. Background Art

[0002] The milling machine is one of the main types of machinery for asphalt pavement maintenance and construction, and one of the main equipment for asphalt concrete pavement maintenance and construction. During the use of the milling machine, a large amount of smoke will be emitted from the contact point between the milling machine and the road surface. The smoke diffused into the air will cause pollution and impact on the environment, and at the same time have an adverse effect on the health of the user.

[0003] In order to reduce the harm of smoke to the health of users, some technologies have proposed relevant dust removal structures to assist the use of milling machines. For example, there is a utility model patent with a publication number of CN214219311U, which proposes an asphalt road marking milling machine. The smoke is sucked into the water through an air pump and mixed with the water to degrade the smoke, thereby preventing the smoke from dispersing outward and affecting the external environment.

[0004] From the above disclosed technical content, theoretically speaking, the implementation of the relevant technical structure is conducive to the dust removal of the milling machine during use. However, according to the description in the above disclosed technical content, the air pump will generate air pressure to suck the smoke into the suction hood, and then use the suction hood to enter the connecting pipe, and then flow into the output pipe through the docking pipe and the air pump, and finally discharged into the water tank to mix with water. In actual use, the milling machine not only has smoke, but also gravel. Driven by the air pump, the mixture of smoke and gravel will enter the air pump through the pipeline and then enter the water tank. At this time, the gravel in the mixture will collide with the inner wall of the air pump when entering the air pump. With the long-term collision between the gravel and the inner wall of the air pump, the air pump will be damaged, thereby affecting the normal use of the air pump. Utility Model Content

[0037] Working principle: When in use, first, the milling roller 2 rotates to construct the road surface, the power of the exhaust fan 12 and the water pump 11 is turned on, and the water pump 11 is turned on to flow the water in the water tank 6. The water in the water tank 6 is filtered by the filter plate 10 and enters the water inlet pipe 35. The water in the water inlet pipe 35 enters the interior of the vertical pipe 36 and then flows through the interior of the main pipeline 37 and then enters the water diversion pipe 21 from the branch pipe 38. The water in the water diversion pipe 21 enters the interior of the water guide pipe 20 and is sprayed from the nozzle 22 to the interior of the dust removal bin 4. Then, the exhaust fan 1 2 is opened to suck the smoke and crushed stones into the dust hood 3 after the milling roller 2 rotates. The mixture of smoke and crushed stones in the dust hood 3 enters the inside of the connecting pipe 17 and then enters the inside of the bent pipe 19 and then falls into the inside of the dust removal bin 4. The mixture of smoke and crushed stones in the dust removal bin 4 is mixed with the water sprayed from the dust removal bin 4 and then falls from the partition 5 to the inside of the water storage tank 6.

The gas after the dust reduction of the crushed stones enters the inside of the exhaust fan 12 from the inside of the air inlet pipe 41 and then is discharged from the air outlet pipe 40 is discharged. Subsequently, after the use of the milling machine is completed, the mixed liquid in the water storage tank 6 is discharged from the water outlet pipe 42, and the power of the rotating motor 33 is turned on. After the rotating motor 33 is turned on, the ball screw 802 is driven to rotate through the connection with the rotating shaft 32. Due to the threaded connection between the ball screw 802 and the ball nut 801, the ball screw 802 rotates in a circular direction and drives the ball nut 801 to move in a horizontal direction. When the ball nut 801 moves, the cleaning brush 7 is driven to move on the bottom surface of the inner wall of the water storage tank 6 through the connection with the spring buckle 9, so that the cleaning brush 7 can be cleaned. The impurities accumulated on the bottom surface of the inner wall of the water tank 6 are pushed to the front of the water tank 6, and the staff can clean the impurities at this time. Finally, when the worn cleaning brush 7 needs to be replaced, the spring buckle 9 is pressed to move from the inside of the fixed block 30 until the spring buckle 9 is separated from the snap block 26, and the cleaning brush 7 is pushed to the inside of the storage box 25. At this time, the spring 24 is in a compressed state, and the snap block 26 can be removed from the fixed block 30, so that the worn cleaning brush 7 can be removed, and then the spring buckle 9 can be popped out from the inside of the snap block 26 to install the new cleaning brush 7.
