A stone grinding and renovation machine, comprising a protective shell and an adjustment mechanism installed in the protective shell, a motor is fixedly installed on the upper end surface of the protective shell, a first sleeve is fixedly installed on the output end of the motor, first through holes are respectively opened on both sides of the first sleeve, the end surface of the first through hole is set as an arc surface, and a plurality of first through holes are provided and are linearly arrayed on the surface of the first sleeve. The adjustment mechanism includes a second sleeve slidably connected to the first sleeve, the second sleeve passes through the lower end surface of the protective shell, and a grinding disc is fixedly connected to one end away from the motor, second through holes are respectively opened on both sides of the second sleeve, the second through holes are directly opposite to the first through holes, a connecting rod is fixedly installed on the inner arc surface of the second sleeve, a V-shaped elastic sheet is clamped on the connecting rod, and clamping columns are fixedly installed on both sides of the V-shaped elastic sheet, and one end of the clamping column away from the side of the V-shaped elastic sheet is set as an arc surface, and the clamping column is clamped in the first through hole and the second through hole.

[0007] Furthermore, a spring is fixedly connected between two sides of the V-shaped elastic sheet.

[0008] Furthermore, a shock absorbing ring is sleeved on the outer surface of the motor, and the upper end surface of the shock absorbing ring is fixedly mounted on the upper surface inside the protective shell.

[0009] Furthermore, two sides of the motor are respectively fixedly connected with fixing rods, and the other ends of the fixing rods are fixedly connected to the inner surface of the protective shell.

[0010] Furthermore, a partition is fixedly installed inside the protective shell, the partition is perpendicular to the bottom surface of the protective shell, a vacuum cleaner is fixedly installed on the upper surface of the protective shell, a dust suction pipe is fixedly installed on one end of the vacuum cleaner away from the upper surface of the protective shell, and the dust suction pipe passes through the lower end surface of the protective shell.

Because the first through holes are provided with a plurality of linear arrays on the surface of the first sleeve, the clamping column can be clamped in different first through holes, that is, different heights can be adjusted, which is easy to operate and improves the work efficiency of the staff.

[0016] When adjusting the height of the device, the V-shaped elastic sheet will be damaged to a certain extent after long-term use. Since a spring is fixedly connected between the two sides of the V-shaped elastic sheet, the V-shaped elastic sheet compresses the spring when adjusting the height. When the clamping column reaches the first through hole, the elastic potential energy of the spring is utilized to effectively protect the V-shaped elastic sheet from being damaged, thereby increasing the service life of the device.

[0022] The present application is further described in detail below in conjunction with the accompanying drawings.

[0023] Example, see Figure 1-Figure 4A stone grinding and renovation machine includes a protective shell 1 and an adjusting mechanism 2 installed in the protective shell 1. A motor 11 is fixedly installed on the upper end surface of the protective shell 1. A first sleeve 12 is fixedly installed on the output end of the motor 11. First through holes 13 are respectively opened on both sides of the first sleeve 12. The end surfaces of the first through holes 13 are set as arc surfaces. A plurality of first through holes 13 are provided and are linearly arrayed on the surface of the first sleeve 12. The adjusting mechanism 2 includes a second sleeve 21 slidably connected to the first sleeve 12, the second sleeve 21 passes through the lower end surface of the protective shell 1, and a grinding disc 22 is fixedly connected to the end away from the motor 11, and second through holes 23 are respectively opened on both sides of the second sleeve 21, and the second through holes 23 are opposite to the first through holes 13, and a connecting rod 24 is fixedly installed on the inner arc surface of the second sleeve 21, and a V-shaped elastic sheet 25 is clamped on the connecting rod 24, and clamping columns 26 are fixedly installed on both sides of the V-shaped elastic sheet 25, and the end of the clamping column 26 away from the side of the V-shaped elastic sheet 25 is set as an arc surface, and the clamping column 26 is clamped in the first through hole 13 and the second through hole 23. When the grinding height of the device needs to be adjusted, because the motor 11 is fixedly installed on the upper end surface of the protective shell 1, the first sleeve 12 is fixedly installed on the output end of the motor 11, and the first sleeve 12 is respectively provided with first through holes 13 on both sides, and the second sleeve 21 is slidably connected in the first sleeve 12, and the grinding disc 22 is fixedly installed on the end of the second sleeve 21 away from the motor 11, and the second through holes 23 are respectively provided on both sides of the second sleeve 21, and the second through holes 23 are just opposite to the first through holes 13, and a connecting rod 24 is fixedly installed on the inner arc surface of the second sleeve 21, and a V-shaped elastic sheet 25 is clamped on the connecting rod 24. The two sides of the clamping column 26 are respectively fixedly installed, and the clamping column 26 is clamped in the first through hole 13 and the second through hole 23. Therefore, by pushing the second sleeve 21 upward or pulling it downward, the clamping column 26 compresses the V-shaped elastic sheet 25 along the inner surface of the first sleeve 12. When the clamping column 26 reaches the first through hole 13, the clamping column 26 is clamped in the first through hole 13. Because the first through holes 13 are provided with a plurality of linear arrays on the surface of the first sleeve 12, the clamping column 26 can be clamped in different first through holes 13, that is, different heights can be adjusted, the operation is simple, and the work efficiency of the staff is improved.

[0024] Reference Figure 1 as well as Figure 2 A spring 27 is fixedly connected between the two sides of the V-shaped elastic sheet 25. When adjusting the height of the device, after long-term use, the V-shaped elastic sheet 25 will be damaged to a certain extent. Because the spring 27 is fixedly connected between the two sides of the V-shaped elastic sheet 25, when adjusting the height, the V-shaped elastic sheet 25 compresses the spring 27. When the clamping column 26 reaches the first through hole 13, the elastic potential energy of the spring 27 is used to effectively protect the V-shaped elastic sheet 25 from being damaged, thereby increasing the service life of the device.

[0025] Reference Figure 1 as well as Figure 2 The outer surface of the motor 11 is sleeved with a damping ring 14, and the upper end surface of the damping ring 14 is fixedly mounted on the upper surface in the protective shell 1. When the device is working, the grinding disc 22 will generate vibration during operation, which will cause damage to the device after long-term use. Because the damping ring 14 is sleeved on the outer surface of the motor 11, and the upper end surface of the damping ring 14 is fixedly mounted on the upper surface in the protective shell 1, the damping ring 14 reduces the vibration generated by the grinding disc 22 during operation, effectively protecting the device from damage and increasing the service life of the device.

[0026] Reference Figure 1 as well as Figure 2 The two sides of the motor 11 are respectively fixedly connected with fixing rods 15, and the other ends of the fixing rods 15 are fixedly connected to the inner surface of the protective shell 1. During the operation of the device, the grinding disc 22 will vibrate when grinding the ground, causing the second sleeve 21 to shake. The shaking of the second sleeve 21 causes the first sleeve 12 to shake, and also causes the motor 11 to shake. Because the two sides of the motor 11 are respectively fixedly connected with fixing rods 15, and the other ends of the fixing rods 15 are fixedly connected to the inner surface of the protective shell 1, the fixing rods 15 effectively prevent the device from shaking, thereby increasing the service life of the device.

[0027] Reference Figure 1 as well as Figure 2 , a partition 16 is fixedly installed in the protective shell 1, the partition 16 is perpendicular to the bottom surface of the protective shell 1, a vacuum cleaner 17 is fixedly installed on the upper surface of the protective shell 1, a vacuum pipe 171 is fixedly installed at one end of the vacuum cleaner 17 away from the upper surface of the protective shell 1, and the vacuum pipe 171 runs through the lower end surface of the protective shell 1. When the device is polishing the floor, a lot of dust will be left, because the partition 16 is fixedly installed in the protective shell 1, the partition 16 is perpendicular to the bottom surface of the protective shell 1, the vacuum cleaner 17 is fixedly installed on the upper surface of the protective shell 1, and a vacuum pipe 171 is fixedly installed at one end of the vacuum cleaner 17 away from the upper surface of the protective shell 1, and the vacuum pipe 171 runs through the lower end surface of the protective shell 1, so when polishing the floor, the dust generated will be absorbed into the vacuum cleaner 17 by the vacuum pipe 171, which effectively improves the work efficiency of the staff.

[0028] Reference Figure 1 as well as Figure 2 The lower end surface of the protective shell 1 is fixedly mounted with a floor brush 18, and the floor brush 18 is located between the grinding disc 22 and the dust suction pipe 171. When the device is grinding the floor, because the floor brush 18 is fixedly mounted on the lower end surface of the protective shell 1, and the floor brush 18 is located between the grinding disc 22 and the dust suction pipe 171, the dust left by grinding can be preliminarily cleaned by the floor brush 18, which effectively improves the work efficiency of the staff.

[0029] Reference Figure 1 Four telescopic frames 19 are fixedly mounted on the lower end surface of the protective shell 1, and the telescopic frames 19 are arranged in a rectangular array on the lower end surface of the protective shell 1. When the device is used, because four telescopic frames 19 are fixedly mounted on the lower end surface of the protective shell 1, and the telescopic frames 19 are arranged in a rectangular array on the lower end surface of the protective shell 1, the device can be adjusted to different heights through the telescopic frames 19, thereby improving the practicality of the device.

[0030] Reference Figure 1 The lower ends of the four telescopic frames 19 are respectively fixedly mounted with universal wheels 191. When the device is used, since the universal wheels 191 are respectively fixedly mounted at the lower ends of the four telescopic frames 19, when the device needs to change the angle for grinding, the universal wheels 191 can be used to change the angle of the device for grinding, which effectively improves the convenience of the device.

[0031] Working principle: When it is necessary to adjust the height of the device for grinding the ground, the second sleeve 21 is pushed upward or pulled downward so that the clamping column 26 compresses the V-shaped elastic sheet 25 along the inner surface of the first sleeve 12. When the clamping column 26 reaches the first through hole 13, the clamping column 26 is clamped in the first through hole 13. The first through holes 13 are set to be several and linearly arrayed on the surface of the first sleeve 12. The clamping column 26 can be clamped in different first through holes 13, that is, different heights can be adjusted. The operation is simple and the work efficiency of the staff is improved.

[0032] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
