The invention discloses a concrete troweling machine based on the technology of the internet of things. The machine comprises a trowling machine cabinet and a purification cabinet at the bottom of the trowling machine cabinet. A base is arranged between the trowling machine cabinet and the purification cabinet. A substrate is arranged on the surface of the base. A rotary shaft is arranged in the middle of the substrate. A support is connected with the top of the rotary shaft. Concrete is fixed to the surface of the support. A first water conveying pipe and a second water conveying pipe are arranged on the two sides of the concrete respectively. A plurality of high-pressure water valves are arranged on the surface of the first water conveying pipe and the surface of the second water conveying pipe respectively. A first lifting cylinder and a second lifting cylinder are connected to the top of the first water conveying pipe and the top of the second water conveying pipe respectively. The first lifting cylinder and the second lifting cylinder are connected to the top of the trowling machine cabinet. The concrete is placed on the support, the rotary shaft is driven by a motor to rotate, ascending and descending of the water conveying pipes are controlled through the lifting cylinders, the concrete is processed through the troweling machine in an omnidirectional and stereoscopic mode, and it is guaranteed that concrete in various shapes and specifications can be effectively processed through the troweling machine.
