Technical Field

[0001] The utility model relates to the technical field of protective nets for troweling machines, and particularly relates to a protective net for facilitating the replacement of troweling blades of a troweling machine. Background Technique

[0002] A floor troweling machine is also called a cement finishing machine. Its main structure is a trowel rotor driven by an electric motor or a gasoline engine. There are 2 - 4 trowel blades installed on the bottom surface of the cross on the middle of the rotor. The existing troweling machines can be divided into two categories according to the type of their working devices: disc troweling machines and blade troweling machines. Among them, the blade troweling machines have two types: single trowel head and double trowel head. According to the power source, they can be divided into two types: electric type and internal combustion type. The disc troweling machine is mainly used for concrete slurry lifting and leveling, while the blade troweling machine is mainly used for troweling in the subsequent construction of concrete. It is a concrete floor construction machine with good construction quality and high efficiency.

[0003] The common protective nets for troweling machines on the market generally use multiple vertical bars, and then use multiple circular fixing rings to connect the multiple vertical bars to form a protective net. Although this kind of protective net is relatively commonly used, the gap between the vertical bars of this kind of protective net is too small. When the trowel blades of the troweling machine are faulty and deformed, it is not convenient to reach in with hands to maintain the trowel blades of the troweling machine. There are too many welding points in the whole traditional protective net, which affects the production efficiency when mass-producing the protective net. Moreover, when the trowel blades are damaged, it is not convenient to replace them.

[0004] Therefore, we propose a protective net for facilitating the replacement of trowel blades of a troweling machine. Summary of the Invention
