When in use, the water pump 5 is started, the water inside the water tank 4 is pumped out through the connecting pipe 6, and the water is transported to the inside of the nozzle 9 through the delivery pipe 7 and the branch pipe 8, and sprayed out through the nozzle 9, so as to achieve the effect of dust reduction and wash the road surface at the same time.

[0023] A brush 11 is installed at the bottom of the base plate 1, and two limit plates 13 are installed at the bottom of the base plate 1. The brush 11 is located between the two limit plates 13, and the two sides of the brush 11 are respectively supported by a moving block 14 and a fixed block 16. The moving block 14 and the fixed block 16 are respectively installed on both sides of the base plate 1. When grinding, the brush 11 can be used to clean the road surface after grinding and the residual water on the road surface can be cleaned at the same time, and the disassembly and assembly of the brush 11 is more convenient, which facilitates the cleaning and replacement of the brush 11 in the later stage.

[0024] Installation grooves are provided on both sides of the upper and lower surfaces of the base plate 1, and the branch pipe 8 is installed inside the installation groove, so that the nozzle 9 is installed at the bottom of the base plate 1, so that water is sprayed out through the nozzle 9 to achieve the effect of dust reduction.

[0025] A baffle 10 is installed at the bottom of the base plate 1. The baffle 10 is located on the rear surface of the grinding disc 3 and does not contact the grinding disc 3. It blocks the debris and gravel generated during grinding to ensure the safety of construction workers.

[0026] A connecting groove is provided at the bottom of the base plate 1 near the rear surface, and a connecting block 12 is installed at the bottom of the brush 11. The connecting block 12 is sleeved inside the connecting groove, and the moving block 14 and the fixing block 16 are respectively located on both sides of the connecting groove. The connecting block 12 is stably connected to the inside of the connecting groove through the moving block 14 and the fixing block 16, so that the brush 11 is stably connected to the bottom of the base plate 1.

[0027] The shift block 14 is connected to one side of the base plate 1 through a rotating shaft, and circular grooves are opened on both sides of the shift block 14, and screws 15 are sleeved inside the circular grooves. A screw hole is opened on one side of the base plate 1, and the screw 15 passes through the circular groove and is threadedly connected to the inside of the screw hole. The shift block 14 is limited by the screw 15, so that it can stably limit the connecting block 12.

[0028] A limiting block is fixed to the rear surface of one of the limiting plates 13 , and the rear surface of the moving block 14 is in contact with the limiting block. The limiting block limits the moving block 14 to prevent the moving block 14 from shaking.

[0029] It should be noted that the utility model is a road construction grinder. When in use, the motor 2 drives the grinding disc 3 to rotate, and then pushes the base plate 1, so that the designated road surface is grinded by the grinding disc 3.

At the same time, the water is sprayed to the road surface to be polished through the nozzle 9, so as to prevent dust from being raised and achieve the effect of dust reduction. At the same time, the road surface can be cleaned through the nozzle 9.

[0030] The brush 11 is then moved back and forth to move the brush 11, and the brush 11 is moved back and forth to move the brush 11. When the brush 11 is in use, the movement of the base plate 1 will drive the brush 11 to move, so that the polished road surface can be cleaned by the movement of the brush 11, and the water remaining on the road surface due to dust reduction can be cleaned at the same time. When the brush 11 needs to be cleaned or replaced later, the screw rod 15 can be rotated to make the screw rod 15 disengage from the inside of the screw hole, so that the shifting block 14 is not limited by the screw rod 15, and then the shifting block 14 is rotated until the shifting block 14 is no longer in contact with the connecting groove, and then the connecting block 12 is pulled out of the inside of the connecting groove, so that the brush 11 is detached from the base plate 1. When installing, the connecting block 12 is sleeved into the inside of the connecting groove, so that the connecting block 12 contacts the fixing block 16, and then the shifting block 14 is rotated in the opposite direction until the shifting block 14 contacts the limiting block, and finally the screw rod 15 is threadedly connected to the inside of the screw hole through the circular groove, so that the shifting block 14 can stably limit the connecting block 12, thereby making the disassembly and assembly of the brush 11 more convenient, and facilitating the cleaning and replacement of the brush 11 in the later stage.
