The motor 1 is used to provide the initial kinetic energy required for driving the flipping operation. The motor shaft 15 is directly connected to the first sun gear 13 to transmit the rotational motion generated by the motor 1 to the planetary gear system. The output end of the motor 1 is drivingly connected to a motor shaft 15. The motor shaft 15 passes through the positioning flange 3 and extends into the interior of the housing 2. A first sun gear 13 is connected to the motor shaft 15. The motor shaft 15 is a key component connecting the motor 1 and the planetary gear system.

Their presence ensures good operating performance even under heavy load conditions. In the present utility model, a sealing ring 18 is installed at the connection between the positioning flange 3 and the housing 2. The sealing ring 18 is installed between the positioning flange 3 and the housing 2 to prevent dust and dirt from entering the interior of the speed reducer, and at the same time avoid leakage of lubricating oil, ensuring the long-term reliable operation of the equipment. The rotating drum 4 in the present utility model is the component that actually performs the material turning action. It realizes the required rotational movement by being connected to the output end of the speed reducer. The mounting portion 21 is an integral part connected to the rotating drum 4, and it is used to fix the rotating drum 4 to a container or other equipment that needs to turn the material.
