Detailed ways

The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, but not to limit the present utility model.

Wherein the same reference numbers in the drawings refer to the same parts throughout.

Example 1

As shown in Figures 1-2, the present utility model provides a rust-removing hand-held grinding device for the bottom of a municipal bridge, comprising a grinding device main body 1, the bottom end of the grinding device main body 1 is fixedly installed with a hand-held handle 2, and the top of the hand-held handle 2 is installed with a hand-held handle 2. The main motor 3, one end of the main motor 3 is fixedly installed with a grinding disc 4, one side of the grinding disc 4 is fixedly installed with a dust suction pipe 5, and the bottom end of the dust suction pipe 5 is installed with a waste dust storage tank 6, and a waste dust storage tank 6 The bottom end is provided with a magnet layer 7, one side of the magnet layer 7 is movably installed with a connecting shaft 8, the other side of the magnet layer 7 is movably installed with a buckle 9, and a filter screen is fixedly installed on the top side of the waste dust storage tank 6 10. A vacuum motor 11 is fixedly installed on the inner side of one end of the vacuum pipe 5 .

Further, the waste dust storage tank 6 and the magnet layer 7 are movably connected with the buckle 9 through the connecting shaft 8, and the rust waste residue and dust sucked by the dust suction pipe 5 are collected into the waste dust storage tank 6, and when the waste dust storage tank 6 is full When the buckle 9 is unlocked, the magnet layer 7 is rotated through the connecting shaft 8 to open and clean the waste in the dust storage tank 6 .

The sanding disc 4 and the hand-held handle 2 are movably connected through the main motor 3, and the user controls the movement of the main motor 3 through the hand-held handle 2, so that the sanding disc 4 can be polished from different angles.

The main motor 3 and the vacuuming motor 11 are electrically connected and externally connected to a power supply. When the user uses the main body 1 of the grinding device, the main motor 3 is activated and the vacuuming motor 11 is also activated to produce linkage.

The dust suction pipe 5 is fixedly connected with the grinding disc 4 and the main motor 3 respectively. The dust suction pipe 5 is placed outside the grinding disc 4 and the main motor 3 so that it can work without affecting the hand-held handle 2 .

Specifically, when the main body of the grinding device is started, the user holds the handle 2 to control the direction of the main motor 3 to control the angle of the grinding disc 4 . The rust slag and dust are sucked into the vacuum pipe 5 by the wind pressure caused by the vacuum motor 11. At this time, the dust storage tank 6 at the lower end of the vacuum pipe 5 will store most of the dust, and the magnet layer 7 at the bottom end will also absorb the rust. The metal waste residue is adsorbed to avoid damage to the main motor 3 and the vacuum motor 11. The filter screen 10 on the top side of the dust storage tank 6 isolates a small part of the missing dust. When the waste in the waste dust storage tank 6 is about to overflow At this time, the magnet layer 7 is disconnected from one end of the solar waste dust storage tank 6 through the buckle 9, and the waste dust storage tank 6 is opened and cleaned by the rotation of the connecting shaft 8.

To sum up, the present invention installs the dust suction pipe 5 on one side of the grinding equipment main body 1, and installs the dust suction motor 11 inside one end of the dust suction pipe 5. The dust suction motor 11 and the main motor 3 of the grinding equipment main body 1 are installed. It is electrically connected so that it starts the vacuuming motor 11 at the same time when the main body 1 of the grinding equipment is started. On the polished rust equipment after grinding by the grinding disc 4, the rust and dust are sucked into the vacuuming pipe 5 by the wind pressure of the vacuuming motor 11, and the rust Due to the adsorption of the magnet layer 7 in the dust storage tank 6 installed at the lower end of the dust suction pipe 5 and the principle of gravity, the rust and most of the dust are adsorbed from the pipe to the dust storage tank 7, and a small part of the dust is also isolated by the filter screen 10. , so that the waste residue after rust removal is controlled to no longer fly around, thereby enhancing the practicability of the utility model.

Finally, it should be noted that the above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. , it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements to some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
