[0003] When constructing municipal road surfaces, a cutting machine is often needed to carry out subsequent repairs on the road surface. However, when using the current road cutting machine, due to the small gravel on the road surface, when the cutting disc contacts the gravel, it is easy to cause the cutting disc to wear, thus shortening its service life. At the same time, small gravel is easy to be generated during cutting, and the gravel is easy to splash everywhere, which is easy to cause certain dangers. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 As shown, a road cutting machine for municipal construction construction includes a machine body 1, a fixing plate 2 is fixedly connected to the top of the machine body 1, an electric push rod 3 is penetrated through the top of the other end of the fixing plate 2, the output shaft of the electric push rod 3 extends to the bottom of the fixing plate 2 and is fixed with an arc plate 4, a motor 5 is arranged below one side of the arc plate 4, a cutting disc 6 is bolted to the output shaft of the arc plate 4, a baffle 7 is rotatably connected to the outer side of the arc plate 4, and a soft pad 9 is arranged on the outer side of the baffle 7, the soft pad 9 is made of rubber, so that the baffle 7 can be protected to prevent its surface from being damaged, and the baffle 7 is flipped to the bottom of the arc plate 4 The rear is lower than the bottom surface of the cutting disk 6, so that the baffle 7 will not contact the ground after being flipped down, and will not affect the cutting of the road surface by the cutting disk 6. The front end of the fixed plate 2 is provided with a limiting structure 8 for limiting the baffle 7. The internal rotation on the right side of the body 1 is connected with a screw rod 10, and a crank 14 is fixed on the top of the screw rod 10. The surface of the screw rod 10 is threadedly connected with a movable block 11, and the outer side of the movable block 11 is fixedly connected with a folding plate 12, and a cleaning plate 13 is fixed to the other end of the folding plate 12. The surface of the body 1 is provided with a spraying structure 16 for spraying the surface of the cutting disk 6.

[0023] The limiting structure 8 includes a pull rod 81, a fixed disk 82, a limiting plate 83 and a spring 84. The surface of the pull rod 81 is movably connected to the inside of the front end of the fixed plate 2. One end of the pull rod 81 is fixed to one side of the fixed disk 82, and the other end of the pull rod 81 is fixed to one side of the limiting plate 83. The spring 84 is sleeved on the surface of the pull rod 81, and the two ends of the spring 84 are respectively fixed between the fixed disk 82 and the bottom of the fixed plate 2. In this way, the elastic force of the spring 84 itself can drive the fixed disk 82 and the pull rod 81 to always move downward, thereby driving the limiting plate 83 to limit the baffle 7.

[0024] The spraying structure 16 includes a water pump 161, a liquid outlet pipe 162, a liquid suction pipe 163 and a nozzle 164. The water pump 161 is fixed on the surface of the top of the body 1.

[0027] Working principle: When in use, the machine body 1 can be pushed to the position where cutting is required, and then before cutting, the crank handle 14 can be turned to drive the screw 10 to rotate, and at the same time drive the movable block 11, the folding plate 12 and the cleaning plate 13 to move downward, so that the cleaning plate 13 contacts the ground, and then pull the pull rod 81 upward, and drive the limit plate 83 to move together, so that the limit plate 83 cancels the limit on the baffle 7, and then the outer surface of the cutting disk 6 can be blocked. During subsequent cutting, as the machine body 1 moves, the cleaning plate 13 can remove impurities such as stones on the cut road surface to avoid damage to the cutting disk 6, and during the cutting process, the cutting disk 6 and the generated dust can be sprayed through the spraying structure 16, and the stones generated during cutting can also be blocked by the baffle 7 to prevent them from splashing outward at will.
