[0001] The present application relates to the technical field of polishing machines, in particular to a polishing machine for polishing wall surfaces. BACKGROUND
[0002] Polishing machines are used for polishing and polishing objects on the surface, and the polishing objects are generally relatively hard objects. In particular, in the wall polishing machine, the polishing object is generally a rough wall with sandstone such as a rough wall. The wall polishing machine usually includes a polishing disc for polishing the wall surface and a machine shell, a motor for driving the polishing disc to rotate is arranged in the machine shell, and a dust collection fan for dust collection. The dust and stone generated in the process of polishing the wall surface by the polishing disc includes hard stone and gravel. However, the machine shell of the polishing machine is usually made of plastic, and the thickness of the machine shell is the same as the normal thickness, so these stone and gravel are sucked into the machine shell by the dust collection fan, and hit the corresponding machine shell of the dust collection fan under high-speed rotation.

[0019] like Figure 1 As shown, the grinder 100 includes a grinder body 1, a grinding disc 2 disposed below the grinder body 1, and a handle 3 connected to the grinder body 1. The grinder body 1 includes a housing, which houses a motor 12 and a dust suction fan 13. The motor 12 drives the dust suction fan 13 and the grinding disc 2. A wear-resistant member 11 is provided on the inner wall of the housing corresponding to the dust suction fan 13. The housing is also provided with a dust discharge port 103, which is connected to a dust discharge hose 15, which is connected to the handle 3. The handle 3 is hollow and communicates with the dust discharge port 103 via the dust discharge hose 15. The bottom of the grinding disc 2 is provided with an opening. When the grinder is in operation, stone grit generated by the grinding disc 2 enters the housing through the opening. The rotation of the dust suction fan 13 creates negative pressure, which draws the stone grit into the dust discharge port 103 and then out of the housing through the dust discharge hose 15. Therefore, when stones and gravel are inside the casing, they often collide with the casing portion at the dust collecting fan 13. In the present grinder 100, a wear-resistant part 11 is added to the casing of this portion to enhance its strength, thereby preventing stones and gravel from penetrating the casing and causing damage and failure of the grinder 100, thereby extending the service life of the grinder 100.
[0020] Preferably, in the embodiment, the machine shell comprises a left half shell 101 and a right half shell 102, and the left half shell 101 and the right half shell 102 are respectively provided with wear-resistant parts 11 around the periphery of the dust collection fan 13. Moreover, the wear-resistant performance of the wear-resistant parts 11 is higher than that of the machine shell. Since the negative pressure generated by the operation of the dust collection fan 13 can adsorb the stones and gravel, the stones and gravel will be mostly gathered around the periphery of the dust collection fan 13, so that the wear-resistant parts 11 arranged around the periphery of the dust collection fan 13 can effectively cover the range of the stones and gravel hitting. The wear-resistant performance of the wear-resistant parts 11 higher than that of the machine shell can also effectively improve the anti-hitting performance of the part of the machine shell, so that the stones and gravel cannot penetrate the wear-resistant parts 11 to protect the machine shell, thereby preventing the machine shell from being penetrated, so as to cause the grinder 100 to be scrapped and invalid.
[0021] Specifically, in the embodiment, the machine shell of the grinder 100 is made of plastic, and the wear-resistant parts 11 are made of metal.
[0022] In another embodiment of the utility model, as shown in Figure 2 The grinder 100 comprises a grinder main body 1, a grinding disc 2 arranged below the grinder main body 1, and a handle 3 connected to the grinder main body 1. The grinder main body 1 comprises a machine shell, and the machine shell contains a motor 12 and a dust collection fan 13. The motor 12 is used to drive the dust collection fan 13 and the grinding disc 2. The main difference from the above-mentioned embodiment is that the machine shell is divided into a fan shielding area A corresponding to the dust collection fan 13 and a non-fan shielding area B, and the ratio of the thickness of the fan shielding area A to the thickness of the non-fan shielding area B is greater than 3 / 2. In the embodiment, the thickness of the fan shielding area A of the machine shell around the dust collection fan 13 is increased, so as to improve the strength of the machine shell in the range hit by the stones and gravel, thereby preventing the machine shell from being penetrated, so as to cause the grinder 100 to be scrapped and invalid.
[0023] The above two embodiments both enhance the strength of the part of the machine shell around the dust collection fan 13, i.e. the part of the machine shell easily hit by the stones and gravel, so as to cope with the hitting of the stones and gravel, prevent the machine shell from being penetrated, so as to cause the grinder to be scrapped and invalid, thereby prolonging the service life of the grinder 100.
[0024] In the above two embodiments, as shown in Figure 1 and 2 The grinder 100 is a vertical wall grinder, i.e. the output shaft of the motor 12 is perpendicular to the grinding disc 2. The handle 3 is connected to the grinder main body 1 through Y-shaped supporting arms 41 and 42, and the two supporting arms 41 and 42 are hingedly connected to the two sides of the grinder main body 1. A speed reduction mechanism 14 is further arranged in the machine shell, and the speed reduction mechanism 14 is connected to the output shaft of the motor 12. The output shaft of the motor 12 drives the grinding disc 2 through the speed reduction mechanism 14. The grinding disc 2 is further provided with a protective cover 21, and the protective cover 21 is provided with a mounting seat 23. The machine shell of the grinding disc 2 is mounted to the mounting seat 23.
[0025] The above merely provides the preferred embodiments of the present application, but is not intended to limit the present application. Even though the present application has been disclosed with the preferred embodiments, the present application is not intended to be limited thereto. Any person skilled in the art, without departing from the technical scope of the present application, can make some simple modifications or modifications to the equivalent embodiments. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application, without departing from the technical scope of the present application, shall still fall within the scope of the present application.
