It is worth to say that the middle of the bottom surface of the water storage barrel 3 is provided with a water outlet pipe 31, a one-way valve is arranged in the water outlet pipe 31, the lower end of the water outlet pipe 31 is connected with a second hose 32, the middle of the receiving cylinder 9 is provided with a liquid distribution cavity 902, a plurality of atomizing nozzles 25 are densely distributed on the bottom surface of the receiving cylinder 9 corresponding to the liquid distribution cavity 902, the left side and the right side of the top surface of the receiving cylinder 9 are both provided with water inlet pipes 26, and the lower end of the second hose 32 penetrates through the bottom surface of the corresponding first through hole 101 and is connected with the upper end of the water inlet pipe 26.

It is worth noting that 2 left end face middle part front sides of U-shaped mounting bracket are equipped with and measure board 8, measure 8 left end faces of board and be equipped with scale 42, the purpose of setting up and measuring board 8 and scale 42 makes the staff can know audio-visual drilling depth to the road and control, prevent to cause the damage to the road bed at the drilling in-process, the practicality of this device has been improved, the perpendicular distance size between the 15 bottom surfaces of left slider and the 8 top surfaces of measurement board is the same with the perpendicular distance size between 20 lower extremes of drill bit to the 4 lower extremes of brake wheel.

In addition, the outer wall of the sliding block 15 is connected with the inner wall of the corresponding through groove 201 in a sliding manner, and the middle part of the circumferential outer wall of the driving shaft 17 is connected with the circumferential inner wall of the fixing hole 901 in a rotating manner.

In addition, the lower end of the supporting leg 37 is provided with a brake wheel 4, and the front side and the rear side of the middle part of the left end surface of the fixed bottom plate 1 are provided with push handles 24.

The working principle is as follows: when a worker needs to drill a road in the process of road construction of traffic engineering, the worker firstly holds a push handle 24 by hand to push the device to a specified position, and aligns a drill bit 20 at the position to be drilled, then puts a proper amount of drying agent into a placing cavity 601, and plugs a processing pipe 6 into the lower side of an air distribution cavity 501, then under the control of a control mechanism, an electric push rod 13 and an electric motor 11 operate, a moving plate 10 drives the electric motor 11, a driving shaft 17, a bearing cylinder 9 and a shielding sleeve 5 to move downwards, the driving shaft 17 drives a rotating disc 19 and the drill bit 20 to rotate, when the drill bit 20 contacts with the road surface, the bottom surface of a fixed ring 18 simultaneously contacts with the road surface, along with the downward drilling of the drill bit 20, the bearing rod 23 moves downwards while rotating, a first spring 22 extends downwards, at the moment, under the push of the moving plate 10, a driving plate 29 is pushed by air pressure and water, the sealing plug 35 is driven to block the air holes 701, water in the water storage barrel 3 immediately flows into the air distribution cavity 902 under the pushing of the pushing plate 7, is sprayed outwards through the atomizing nozzle 25 and is combined with flying dust, in addition, in the process of drilling downwards by the drill bit 20, under the control of the control mechanism, the induced draft fan 38 operates to discharge the air in the air distribution cavity 501 outwards, the air distribution cavity 501 immediately assumes a negative pressure state, dust in the inner side of the shielding sleeve 5 immediately enters the air distribution cavity 501 through the dust suction pipe 33 and the L-shaped dust removal pipe 27, part of water entering along with the air distribution cavity is absorbed by the drying agent, in the process, a worker observes the scale 42 aligned with the sliding block 15, and when the required drilling depth is reached, under the control action of the control mechanism, the electric push rod 13 resets to drive the moving plate 10, the motor 11 and the drill bit 20 to move upwards, therefore, the worker can complete the operation of drilling the road in the process of road construction of the traffic engineering.
