[0003] Floor grinder is mainly used for grinding the ground. It can effectively grind terrazzo, concrete surface, epoxy mortar layer and old epoxy floor, etc. It is light, flexible and efficient.

[0004] When the grinder is dry grinding the ground, there is often a lot of dust, so a dust suction device is needed to perform dust suction operations. Most existing dust suction grinders use a single fan for dust suction, and the dust suction effect is poor. For example, the Chinese public invention patent with patent announcement number CN114700823A discloses a combined grinder that can perform dust suction when the grinder is in dry grinding operation. However, in the above scheme, the vacuum cleaner body needs to be installed on the combined frame, so that during the dust suction operation, the combined frame needs to be connected to the grinding frame before the dust suction operation can be performed, and the operation is relatively cumbersome. In addition, the combined frame is large in size, which will greatly increase the overall space occupied by the grinder after installation, making it inconvenient for the grinder to enter a small area for grinding.

The fan 21 is fixedly mounted on the lower frame 11, the dust collection bucket assembly 3 is mounted on the upper frame 12, the dust collection bucket assembly 3 and the fan 21 are interconnected, the dust collection pipe 22 is connected to the lower frame 11, the front end of the dust collection pipe 22 extends into the gear box, and the rear end of the dust collection pipe 22 is connected to the dust collection bucket assembly 3.

[0025] In this embodiment, two fans 21 are provided, and a vortex air pump can be selected for the fans 21. The lower frame 11 includes a bearing plate 111, and a mounting cavity 112 is formed between the bearing plate 111 and the upper frame 12. The fans 21 are symmetrically mounted in the mounting cavity 112. Specifically, the lower end of the fan 21 is fixedly mounted on the bearing plate 111 by screws. With the above structure, the fan 21 can be directly mounted on the grinding machine frame 1, simplifying the mounting structure, effectively reducing the overall space occupied by the grinding machine, and making the installation faster. In addition, the upper frame 12 cover is arranged on the periphery of the fan 21, which can play a shielding and protective effect.

[0026] In this embodiment, in order to facilitate the installation of the dust bucket assembly 3, the dust bucket assembly 3 includes a box body 31 and a filter element 32.
