Description

Technical Field

[0001] The utility model relates to the technical field of decoration and renovation, and in particular to a decoration and renovation wall polishing device with dust reduction effect. Background Art

[0002] Since some small defects often appear on the wall during the putty scraping process, they must be compensated by polishing. For this reason, the wall needs to be polished to make the putty surface smoother and more uniform in thickness, thereby enhancing the adsorption of latex paint and the final coating effect, and avoiding some problems that may be caused by differences in surface structure.

[0003] When grinding walls, workers usually use handheld grinders to grind the parts of the walls that need to be grinded. However, the existing grinders cannot handle the dust generated during the grinding process, which causes the dust generated during the grinding process to be scattered everywhere. Workers are prone to inhaling the dust into their lungs when breathing, which in turn affects their physical and mental health. Utility Model Content

[0004] In order to overcome the shortcomings mentioned in the above background technology, the purpose of the utility model is to provide a decorative wall grinding device with dust reduction effect.

[0009] As an improvement of the above solution, two filter plates are provided, and the facing ends of the two filter plates are rotatably connected to the mounting frame, and symmetrical discharge ports are provided on the mounting plates.

[0010] The utility model achieves close contact between the installation shell and the side of the wall, and utilizes the vacuum pump to extract the gas in the installation shell through the fixed shell, the discharge pipe and the discharge shell. Therefore, the dust generated by the grinding disc grinding the wall can be extracted, and the extracted gas is filtered through the filter plate so that the dust in the gas is intercepted by the filter plate.

DETAILED DESCRIPTION

[0016] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0017] A decorative wall polishing device with dust reduction effect, such as Figure 1-Figure 4As shown, it includes a mounting shell 1, and the front and rear sides of the left side wall of the mounting shell 1 are fixedly connected with a grip rod 2, the middle part of the left side wall of the mounting shell 1 is fixedly connected with a reduction motor 3, the right end of the output shaft of the reduction motor 3 extends to the inner side of the mounting shell 1 and is fixedly connected with a grinding disc 4, and the right side wall of the mounting shell 1 is arranged in a rectangular array with sliding grooves, and a contact ball 7 is rotatably provided in the sliding groove of the mounting shell 1. After the contact ball 7 moves into the sliding groove, the right end of the contact ball 7 is in the same vertical plane as the right side surface of the mounting shell 1, and the contact ball 7 on the mounting shell 1 is brought into contact with the wall surface, and the mounting shell 1 is continuously pushed to move in the direction of the wall surface, so that the contact ball 7 moves into the sliding groove of the mounting shell 1. At this time, the mounting shell 1 is in close contact with the side surface of the wall to form a closed space, so as to avoid the dust generated when the reduction motor 3 drives the grinding disc 4 to rotate and grind the wall surface to escape outward, resulting in inhalation into the body to cause physical harm. At this time, the contact ball 7 is used to facilitate the movement of the mounting shell 1 for guidance, and reduce the friction generated during the movement. A dust suction component is provided on the lower side of the mounting shell 1.

[0018] The dust collection assembly includes a discharge shell 8 connected to the bottom of the mounting shell 1, the bottom of the discharge shell 8 is fixedly connected to the mounting plate 10 through a support rod 9, the bottom of the discharge shell 8 is connected to a discharge pipe 11, a vacuum pump 16 is provided in the middle of the mounting plate 10, and a filter element is provided between the discharge pipe 11 and the air inlet end of the vacuum pump 16. The vacuum pump 16 is operated to extract the gas in the mounting shell 1 through the discharge pipe 11 and the discharge shell 8, and the dust in the gas is filtered out through the filter element.

[0019] The filter element includes a fixed shell 12 connected to the bottom of the discharge pipe 11, and a mounting frame 13 is slidably connected in the fixed shell 12. The top of the mounting frame 13 is fixedly connected with symmetrically distributed limit plates 14, and the mounting frame 13 is in the shape of a "sun". A handle 15 is fixedly connected to the right wall of the mounting frame 13. The air inlet end of the vacuum pump 16 is connected to the bottom of the fixed shell 12. Two filter plates 17 are arranged in the mounting frame 13, and the opposite ends of the two filter plates 17 are rotatably connected to the mounting frame 13. Symmetrical discharge ports are opened on the mounting plate 10. The mounting frame 13 is pulled by the handle 15 to move, so that the filter plate 17 on the left side moves into the fixed shell 12, and the filter plate 17 on the right side is now moved and swung downward under the action of gravity, so that the dust on it is discharged through the discharge port on the mounting plate 10. For this reason, it can avoid excessive dust filtered out on the filter plate 17, thereby affecting the extraction of gas and causing obstacles to wall polishing.

[0020] During use, the user makes the contact ball 7 on the installation shell 1 contact with the wall by holding the handle 2, and then the user pushes the installation shell 1 to move in the direction of the wall, so that the contact ball 7 can be moved into the sliding groove of the installation shell 1, so that the installation shell 1 and the side of the wall are in close contact to form a closed space. At this time, the contact ball 7 is used to guide the movement of the installation shell 1 and reduce the friction generated during the movement, which is convenient for grinding different positions of the wall, reducing the resistance during the movement of the installation shell 1, and thus reducing the labor intensity of the user. Then the user starts the reduction motor 3 to rotate the grinding disc 4, and the grinding disc 4 rotates to grind the area covered by the installation shell 1. In this process, the vacuum pump 16 is started at the same time, and the vacuum pump 16 extracts the gas in the installation shell 1 through the fixed shell 12, the discharge pipe 11 and the discharge shell 8. , for this purpose, the grinding disc 4 can extract the dust generated by wall grinding, and the extracted gas can be filtered by the filter plate 17, so that the dust in the gas is intercepted by the filter plate 17. After a period of time, the user pulls the mounting frame 13 to move by the handle 15, so that the filter plate 17 on the left side swings upward and moves to the right, so that the filter plate 17 on the left side enters the fixed shell 12, and the filter plate 17 on the right side moves to the right and swings downward under the action of gravity, so that the dust on it is discharged through the discharge port on the mounting plate 10. For this purpose, it can be avoided that too much dust is filtered out on the filter plate 17, thereby affecting the extraction of gas and causing obstruction to wall grinding. After completing the wall grinding, the user turns off the reduction motor 3 and the air pump 16. In the above manner, it can be prevented that the workers inhale the dust generated by grinding into the body when grinding the wall, thereby causing harm to the body.
