[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] Example 1

[0031] This embodiment provides a protective cover for a polishing machine, such as Figure 1 As shown, it includes a fixed protective component 1, a movable protective component 2, and a connecting assembly 3. The movable protective component 2 is detachably connected to the fixed protective component 1 through the connecting assembly 3. The movable protective component 2 includes at least two types, one of which is selected according to different construction areas.

[0032] The polishing machine protective cover of this embodiment is installed on the upper surface of the polishing wheel of the polishing machine. It can effectively protect the dust and debris generated during polishing from splashing to the outside. When it is necessary to polish the edge of the ground, the entire ground can be polished by replacing the movable protective part 2.

[0033] The fixed protective component 1 is a semi-circular shell, which is fixedly installed on the polishing machine by screwing, snapping or other means during use.

[0034] Preferred, such as Figure 1 As shown, the movable protective component 2 is also a semi-circular shell. After the movable protective component 2 and the two diameter sides of the fixed protective component 1 are fitted together, they can cover the upper surface of the grinding wheel in order to block and collect the dust and debris generated during grinding.

[0035] The movable protective component 2 includes either a first movable component 21 or a second movable component 22.

[0036] like Figure 1 As shown, the first movable part 21 is used for large-area grinding of the ground. The first movable part 21 is a semi-annular shell, and the protective cover formed by connecting it with the fixed protective part 1 is designed to cover the grinding wheel from the inner end face and the outer periphery, which can block the dust and debris generated during ground grinding, making it easier for other components inside the grinder to collect such impurities. Figure 2 As shown, the second movable part 22 is used for installation during construction at the edge of the ground. The protective cover formed by the second movable part 22 and the fixed protective part 1 is designed to cover the grinding wheel from the inner end face and the outer periphery direction, except for the outer periphery of the grinding wheel which is exposed.

[0037] The second movable component 22 includes a protective plate 221, a guide portion 222, and a grinding groove 223. The protective plate 221 is also an annular plate, with one side connected to the fixed protective component 1 and the guide portion 222 fixedly provided on the other side. The outer surface of the guide portion 222 is provided with a guide plane 2221, which is perpendicular to the end face of the grinding wheel and flush with the edge of the grinding wheel.

[0038] Preferably, there are two symmetrically arranged guide sections 222, and the guide planes 2221 are square. The distance between the outer edges of the two guide planes 2221 is greater than the width of the movable protective member 2, which allows the guide planes 2221 to fit more stably against the wall during the movement of the grinder. The grinding groove 223 is formed on one side of the protective plate 221 and the guide section 222, and is used to accommodate the grinding wheel together with the space inside the fixed protective member 1.

[0039] When it is necessary to carry out construction on the edge or corner of the ground, the second movable part 22 is installed and connected with the fixed protective part 1. In use, the guide plane 2221 is attached to the wall, and then the grinder is pushed. Under the guidance of the guide part 222, the grinder moves stably along the wall. The grinding wheel in the grinding groove 223 grinds the edge or corner of the ground, effectively expanding the construction range of the grinder and improving the construction quality and efficiency.

[0040] Furthermore, such as Figure 1As shown, the connecting assembly 3 includes a first connector 31, a second connector 32, a rotating screw 33, and a nut 34. Preferably, two sets of connecting assemblies 3 are provided, symmetrically arranged on both sides of the polishing machine protective cover.

[0041] The second connector 32 is fixed to the diameter side of the fixed protective member 1 and is used to install the rotating screw 33.

[0042] One end of the rotating screw 33 is rotatably connected to the second connecting member 32, allowing the rotating screw 33 to rotate around the connection point in both directions: the fixed protective member 1 and the movable protective member 2. The other end of the rotating screw 33 is threadedly connected to the nut 34.

[0043] The first connector 31 is fixed to the diameter side of the movable protective member 2 and is arranged opposite to the second connector 32 after assembly. The surface of the second connector 32 is provided with a through groove 322 that matches the rotating screw 33. The through groove 322 is located on the rotation radius of the rotating screw 33. When the rotating screw 33 rotates in the direction of the movable protective member 2, the rod of the rotating screw 33 can rotate into the through groove 322.

[0044] When assembling the polishing machine protective cover of this embodiment, the diameter edge of the movable protective member 2 is aligned with the diameter edge of the fixed protective member 1, aligning the first connecting member 31 and the second connecting member 32 on both sides. The rotating screw 33 is rotated towards the movable protective member 2, causing the screw 33 to enter the through groove 322. The nuts 34 on both sides are rotated, moving them towards the second connecting member 32. The nuts 34 then move the second connecting member 32 towards the first connecting member 31, gradually reducing the gap between the fixed protective member 1 and the movable protective member 2 until the movable protective member 2 and the fixed protective member 1 are assembled and locked. When the movable protective member 2 needs to be replaced, simply rotate the nuts 34 on both sides in the opposite direction. After the connection between the fixed protective member 1 and the movable protective member 2 loosens, rotate the rotating screw 33 outwards to remove it from the through groove 322, and the movable protective member 2 can be removed.

[0045] The connecting component 3 in this embodiment enables the quick assembly and disassembly of the movable protective component 2, avoiding the impact of the replacement process of the movable protective component 2 on the construction speed.

[0046] Example 2

[0047] This embodiment provides a polishing machine for construction, which is equipped with the polishing machine protective cover provided in Embodiment 1.

[0048] like Figure 3 and Figure 4 As shown, the construction polishing machine of this embodiment includes a moving unit 100, a driving unit 200, a polishing unit 300, a protective cover 400, and an adjustment unit 500.

[0049] The adjustment unit 500 can move the drive unit 200, the grinding unit 300 and the protective cover 400 to one side as a whole, so as to prevent the width of the moving unit 100 from obstructing the guide plane 2221 from fitting with the wall when working on the edge or corner of the ground.

[0050] Preferred, such as Figure 5 As shown, the adjustment unit 500 includes a movable end 501, a driving component 502, and a moving slot 503. The movable end 501 is fixedly installed at the rear end of the driving unit 200. The moving unit 100 has a moving slot 503 at the front. The driving component 502 is installed in the moving slot 503 and can drive the movable end 501 to move left and right in the moving slot 503.

[0051] When processing is required at the edge of the floor during use, after replacing the movable protective part 2, the guide plane 2221 cannot fit against the wall at the edge of the floor due to the wider width of the moving unit 100. At this time, by activating the drive assembly 502, the moving end 501 moves inside the moving groove 503, driving the drive unit 200, grinding unit 300 and protective cover 400 to move to one side as a whole, so that the guide plane 2221 can protrude from the side of the moving unit 100, thereby achieving fit against the wall at the edge of the floor, and thus successfully completing the grinding work at the edge of the floor.

[0052] Optionally, the drive assembly 502 includes a lead screw and a guide rod, and the moving end 501 is threadedly connected to the lead screw and the guide rod and slidably connected to them, respectively.

[0053] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
