[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] The utility model provides Figure 1-3 As shown, an industrial dust-free dry grinder comprises an industrial dust-free dry grinder body 1 and a plug-in mounting assembly 4 arranged at the front end of the industrial dust-free dry grinder body 1; a connecting rubber tube 6 is connected at the middle position of the plug-in mounting assembly 4; a fitting sheath 15 is arranged at the outer position of the connecting rubber tube 6 where the plug-in mounting assembly 4 is fitted, and a sheath through hole 19 is arranged on the inner side of the fitting sheath 15 and on the outer side near the rear end, an exhaust outer column 17 is arranged at the upper end of the fitting sheath 15, an inner telescopic body 18 is arranged at the middle position of the exhaust outer column 17, and the upper A rotating threaded knob 16 is provided at the end position, and the fitting sleeve 15 is made of silicone material. After the fitting sleeve 15 is fitted with the connecting rubber tube 6 and the inner side surface of the plug-in installation component 4, the rotating threaded knob 16 is turned to pull up the inner telescopic body 18 to evacuate air and reduce the pressure at the fitting surface position. After reducing the pressure at the fitting position, the fitting sleeve 15 will be more tightly contacted and connected with the connecting rubber tube 6 and the inner side surface of the plug-in installation component 4. The fitting sleeve 15 has a certain protective effect against wear and tear and prevents the connecting rubber tube 6 from stretching and falling off, thereby improving the service life of the industrial dust-free dry grinder.

[0022] like Figure 1As shown, a hand-held grinder 7 is arranged at the end position of the connecting rubber tube 6, a control button 5 is arranged on the upper side of the hand-held grinder 7, a grinding disc 8 is arranged at the lower side position of the hand-held grinder 7, the hand-held grinder 7 is connected to the connecting rubber tube 6, and the grinding disc 8 can be rotated and ground by pressing the control button 5.

[0023] like Figure 1 As shown, a front universal wheel 14 is provided at the lower end position near the front side of the industrial dust-free dry grinder body 1, and the front universal wheel 14 is installed and connected to the bottom corner position of the industrial dust-free dry grinder body 1 by screws. A rear wheel 13 is provided at the rear end position of the front universal wheel 14, and the rear wheel 13 is installed at the two sides of the industrial dust-free dry grinder body 1 near the rear end by screws. Both the front universal wheel 14 and the rear wheel 13 have the function of rolling instead of sliding to reduce the friction between the industrial dust-free dry grinder body 1 and the ground and facilitate movement. At the same time, the front universal wheel 14 can rotate, so the industrial dust-free dry grinder body 1 can adjust the moving direction conveniently.

[0024] like Figure 1 As shown, a control display screen 2 is provided at the oblique front position of the industrial dust-free dry grinding machine body 1, and a control knob 3 is provided at the lower end position of the control display screen 2.

The setting of the rear push rod 9 can increase a certain height, so that the staff can be in a comfortable position to move the industrial dust-free dry grinding machine body 1. The push rod sleeve 10 is made of rubber material, and the rubber can increase the feel between the user's hand, so that the user can move more comfortably.

[0028] During operation, after the power is turned on, the user grinds the designated position through the grinding disc 8 by holding the handheld grinder 7. Because there is a through hole at the grinding disc 8 that is connected to the connecting rubber tube 6, a negative pressure is formed at the grinding disc 8 under the suction action of the industrial dust-free dry grinding body 1. The negative pressure can extract the dust generated when the grinding disc 8 is grinded, thereby avoiding the dust from being blown away. After the grinding is completed, turn off the button and unplug the plug.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
