Description

Technical Field

[0001] The utility model relates to the technical field of floor polishing robots, in particular to an automatic floor polishing device. Background Art

[0002] The floor trowel polishes the floor through the contact between the impeller and the ground, and its rotation speed is controlled by an electronic program. With the development of technology, handheld floor trowels can also achieve the function of runaway shutdown through circuit control.

[0003] Chinese Patent: CN217128888U (A ground trowel device for civil engineering) discloses that both sides of the device body are fixedly connected with fixed boxes, the interior of the fixed boxes is movably connected with a moving mechanism, and the side of the fixed box away from the device body is fixedly connected with a support plate, which solves the problem that when performing troweling operations on the ground in multiple areas with long distances, workers need to repeatedly lift the trowel device for transfer, resulting in a waste of manpower and thus affecting the troweling effect.

[0004] However, the existing device still has the following problems: 1. In order to prevent cement from splashing, a protective net is installed on the outside of the trowel machine. The protective net is fixed to the outer shell of the trowel machine by bolts. When cleaning, the protective net needs to be removed, and the existing bolts need to be removed with tools, which is inconvenient. 2. After using the trowel machine, the trowel machine needs to be transported to the placement table. The existing technology installs a frame on the top of the trowel machine to pull up the trowel machine for movement, but this movement method is more laborious. If wheels are installed on the trowel machine, it will leave marks on the cement floor during troweling, affecting the processing progress.

[0005] Based on this, the utility model designs an automatic floor polishing device to solve the above problems. Utility Model Content
