[0036] Embodiment 1:

[0037] See also Figures 1 to 5 In the embodiment of the utility model, a wall grinding structure includes a base 1 and a grinder 15. A hydraulic rod 2 is fixedly installed on the top surface of the base 1. The top of the hydraulic rod 2 is fixedly connected to a connecting block 6. The end of the connecting block 6 away from the hydraulic rod 2 is fixedly connected to a suspension rod 9 arranged parallel to the hydraulic rod 2. A mounting plate 14 arranged vertically to the suspension rod 9 is arranged directly below the suspension rod 9. A force adjustment component is fixedly installed in the middle position of the top surface of the mounting plate 14. The bottom end of the suspension rod 9 is transmission-connected to the force adjustment component.

[0038] A reciprocating mechanism is fixedly mounted on the bottom surface of the mounting plate 14, a mounting assembly is provided in the reciprocating mechanism, and a grinder 15 is detachably fixedly mounted in the mounting assembly;

[0039] A moving mechanism is provided on the bottom surface of the base 1, and the moving mechanism includes four pillars 12 fixedly installed at four corners of the bottom surface of the base 1, and a universal wheel 13 is fixedly installed at the bottom end of the pillar 12. A stabilizing component located below the base 1 is provided between the four pillars 12.

[0040] The reciprocating mechanism includes a mounting seat 18 and a motor 19. The mounting seats 18 are fixedly mounted on the bottom surface of the mounting plate 14 near both ends thereof. A second screw rod 21 is rotatably mounted between the two mounting seats 18, and two second slide bars 22 symmetrically distributed about the mounting seats 18 are fixedly connected between the two mounting seats 18.

[0041] The motor 19 is fixedly mounted on the outer side of a mounting seat 18 . The end of the second screw rod 21 close to the motor 19 rotates through the mounting seat 18 at the corresponding position and is fixedly connected to the output shaft end of the motor 19 .

[0042] The mounting assembly includes a slide seat 20, the slide seat 20 is connected to two second slide rods 22 by a through-type sliding connection, and the slide seat 20 is connected to the second screw rod 21 by a through-type threaded connection;

[0043] Two symmetrically arranged elastic telescopic rods 16 are fixedly connected to the outer side of the slide 20, and a mounting plate 17 is fixedly installed on one end of the two elastic telescopic rods 16 away from the slide 20, and a grinder 15 is detachably fixedly installed on one side of the mounting plate 17 away from the elastic telescopic rods 16;

[0044] A force scale 31 is provided on the periphery of the telescopic portion of the elastic telescopic rod 16 .

[0045] The force adjustment assembly includes a fixed seat 27, and the fixed seats 27 are fixedly installed at the middle positions on both sides of the top surface of the mounting plate 14, and a first screw rod 29 that passes through the suspension rod 9 through a thread is rotatably installed between the two fixed seats 27, and two first sliding rods 30 that slide through the suspension rod 9 are fixedly connected between the two fixed seats 27;

[0046] One end of the first screw rod 29 away from the base 1 rotates through the fixed seat 27 at the corresponding position and is fixedly mounted with a hand wheel 28 .

[0047] When the utility model is in use:

[0048] Move the device body to the wall so that the Dharma disk of the grinder 15 is in compression contact with the wall; then, the static friction between the device body and the ground is increased by a stabilizing component to prevent the device body from changing position during the grinding process, so that the force between the grinder 15 and the wall remains stable, thereby improving the grinding quality;

[0049] Then, the extrusion force between the grinding disc of the grinder 15 and the wall is adjusted by the force adjustment component. Specifically, the first screw rod 29 is rotated by the hand wheel 28. The rotation of the first screw rod 29 drives the suspension rod 9 and the first slide rod 30 to slide relative to each other, so that the position between the mounting plate 14 and the suspension rod 9 is changed, and the distance between the mounting plate 14 and the wall is changed. Correspondingly, the elastic support force of the elastic telescopic rod 16 on the grinder 15 is changed. The specific force can be precisely adjusted by observing the force scale 31 on the elastic telescopic rod 16.

[0050] Then, the motor 19 is started, and the second screw rod 21 is driven by the motor 19 to perform periodic forward and reverse rotation, thereby driving the slide 20 to perform reciprocating linear motion along the length direction of the mounting plate 14, and the movement of the slide 20 drives the grinder 15 to move and grind the wall surface; when the slide 20 completes the linear motion on one side, the hydraulic rod 2 extends a distance to drive the mounting plate 14 to rise, thereby causing the grinder 15 to rise a distance, and then performs linear motion to perform grinding work, and the overall grinding work of the wall surface is completed in this reciprocating manner.

[0051] In the utility model, the grinding force can be accurately set before grinding by cooperating with the force adjustment component and the elastic telescopic rod 16, so that the utility model can select the corresponding grinding force according to the different conditions of the wall, thereby improving the practicality of the device. In addition, during the grinding process, the device body and the ground remain stationary, and the pressure between the grinding disc and the wall is provided by the elastic telescopic rod 16. Compared with the prior art, the force application stability in the whole process is effectively improved, thereby improving the grinding quality of the wall.

[0052] In the prior art, the wall surface is polished by driving the polisher to rise and fall during a single polishing process. In the utility model, the reciprocating mechanism and the hydraulic rod 2 are coordinated to drive the polisher 15 to polish the wall surface within a certain plane, thereby increasing the single polishing area and improving the polishing efficiency to a certain extent.

[0056] During the lifting process of the suspension rod 9, the connecting rod 8 drives the ring 7 to slide accordingly on the periphery of the limit rod 3. That is, during the lifting process, the connecting rod 8 maintains support for the suspension rod 9 between the limit rod 3 and the suspension rod 9, thereby improving the stability of the suspension rod 9 and preventing the bottom end of the suspension rod 9 from being deformed due to grinding pressure.

[0061] By turning the threaded rod 11 through the knob 10, the lifting plate 23 drives the counterweight block 26 to descend until the friction pad 25 is pressed into contact with the ground, thereby increasing the static friction between the device body and the ground, avoiding the problem of reduced grinding quality caused by the movement of the device body during the grinding process.
