[0016] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0017] like Figures 1 to 5 The present invention discloses a dust-proof wall grinding machine, comprising a movable seat 1, a water supply mechanism 2 is arranged on one side of the top of the movable seat, an electric push rod 3 is installed on the other side, a support box 4 is installed on the top of the electric push rod, a grinding motor 5 is installed inside the support box, a rotating shaft 6 is installed on the output end of the grinding motor, a protective cover 7 is installed on one side of the support box, a sponge ring 11 is arranged around the periphery of the protective cover, a plurality of powder sticks 14 are evenly installed inside the protective cover, the powder sticks are distributed in a ring shape on the protective cover, the rotating shaft extends outward to the inside of the protective cover, a grinding disc 9 is installed at the end of the rotating shaft, a protective mechanism 8 is arranged on the side of the grinding disc close to the rotating shaft, a baffle 10 is installed on one side of the bottom end of the protective cover, A guide pipe 12 is installed inside the protective cover. The guide pipe 12 extends outward from the protective cover 7 and is connected to the water supply mechanism 2 through the bellows 204. The part of the guide pipe 12 inside the protective cover 7 is annular, and a plurality of atomizing nozzles 13 are evenly installed on the inner side of the ring of the annular guide pipe inside the protective cover 7. In this embodiment, the number of atomizing nozzles is set to six. The water supplied by the water supply mechanism 2 is guided into the protective cover 7 through the guide pipe 12 and then sprayed from the atomizing nozzle 13 to wet the powder stick 14. When in use, the atomizing nozzle 13 is used to disperse the water flow, so that the powder stick 14 is wetted, and the dust around the grinding disc 9 is intercepted to improve its dust interception effect, which is beneficial to reduce the dispersion of dust.

[0018] Preferably, the water supply mechanism includes a water supply tank 201, which is installed at the top of the movable seat. A water inlet pipe 202 is installed on one side of the top of the water supply tank, and a water pump 203 is installed on the other side. A suction pipe 205 is connected between one side of the water pump and the water supply tank. A bellows 204 is installed on the top of the water pump, and the top of the bellows is connected to the guide pipe to facilitate the transmission of water from bottom to top.

[0019] Preferably, the protective mechanism includes a first protective sleeve 801, which is installed on one side of the grinding disc 9, and a second protective sleeve 802 is sleeved inside the first protective sleeve 801, one end of the second protective sleeve is connected to the inside of the protective cover 7, and a guide groove 804 is opened on the outside of the second protective sleeve, and balls 803 are evenly installed inside the guide groove, and the other side of the balls are connected to the inside of the first protective sleeve 801. The balls are distributed in a ring shape on the first protective sleeve to wrap and protect the rotating shaft, thereby preventing water from spraying to the outside of the rotating shaft, increasing its service life, and through the action of the balls, the rotation of the grinding disc is not easily affected.

[0020] Preferably, telescopic rods 15 are installed on both sides of the bottom end of the support box, and the bottom ends of the telescopic rods are connected to the top end of the moving seat. The telescopic rods follow the rise and fall of the electric push rod 3 to perform telescopic movements, thereby improving the stability of the support box when rising or falling.

[0021] Preferably, powder sticking burrs are evenly installed on the outside of the powder sticking stick to improve the adhesion effect of the powder stick on dust.

[0022] Working principle:

[0023] When the utility model is in use, firstly, the electric push rod 3 is started to extend or shorten it, thereby driving the support box 4 to rise or fall, and the telescopic rod 15 is extended or shortened, and then the positions of the protective cover 7 and the grinding disc 9 are adjusted accordingly, and then the grinding motor 5 is started to rotate the rotating shaft 6, so that the grinding disc 9 rotates synchronously, so that it can grind the wall surface flat.

[0024] Secondly, through the water inlet pipe 202, water is filled into the water supply tank 201. Before grinding the wall, the water pump 203 is started so that the water suction pipe 205 pumps the water into the inside of the bellows 204, and then transmits the water to the inside of the guide pipe 12 and is sprayed out by the atomizing nozzle 13, thereby achieving the wetting effect of the powder stick 14, so as to improve the adhesion effect of the powder stick 14 on the dust.

[0025] Finally, through the action of the sponge ring 11, one side of the protective cover 7 is pressed against the wall, so that the protective cover 7 covers the grinding position of the grinding disc 9 to prevent the dust from the wall grinding from diffusing outward. At the same time, the powder stick 14 is used to capture the dust inside the protective cover 7, thereby realizing the dust collection effect. And through the action of the baffle 10, the falling dust is collected to prevent the protective cover 7 from causing dust to fall during the movement.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
