Description

Technical Field

[0001] The utility model relates to the technical field of trowel machines, in particular to a grinding disc structure of a trowel machine. Background Art

[0002] The trowel is also called a finishing machine. Its main structure is a trowel rotor driven by a gasoline engine. A trowel is installed on the bottom of the cross in the middle of the rotor. The tilt direction of the trowel is consistent with the rotation direction of the rotor. The gasoline engine drives the V-belt to rotate the trowel rotor. The surface constructed by it is smoother and flatter than the surface constructed by manual labor. It can greatly improve the density and wear resistance of the concrete surface, and improve the work efficiency by more than 10 times compared with manual labor.

[0003] China Announcement No.: CN213978471U discloses a grinding disc protection structure of a trowel machine. The device of the application protects the grinding disc through a protective cover and a protective box to prevent the grinding disc from being smashed by external objects and to prevent the dirt on the grinding disc from dirtying the room. Multiple grinding discs are positioned by a fixed component to prevent the grinding discs from tipping over and breaking when the device is transported or hit. However, the fixed component is composed of a spring, an inner rod and an outer rod connected in a sliding manner, and other components. When the number of grinding discs is small, the positioning of the grinding discs by the fixed component is unstable. When the device is transported or hit, adjacent grinding discs may collide with each other and be damaged. In addition, the protective cover is rotatably connected to the center of the upper end of the protective box, and a fixed component is also provided in the protective box, which makes it inconvenient to clean the protective box.
