[0029] The striking assembly includes a plurality of spaced and subdivided components 8, and the components 8 are rigidly connected to the main shaft 1 so that the components 8 rotate synchronously with the main shaft 1. Each component 8 is provided with a striking hammer 9, and a gap is distributed between two adjacent striking hammers.

The other end of the connecting rod 10 is connected to a cover plate 11, and the cover plate 11 is locked on the adjacent components by bolts. Through the above structural arrangement, the striking assembly can stably follow the movement of the main shaft 1.
[0030] A bearing cooling device for a crushing powder receiving machine adopts a dual cooling system to remove heat from the bearing and reduce bearing damage. The dual cooling system includes a cooling water circulation system and an oil circuit cooling system.
[0031] The cooling water circulation system in this embodiment is consistent with the existing cooling system, including a cooling water flow channel arranged on the bearing seat 3, the cooling water flow channel forms a water inlet and a water return port 6 on the bearing seat 3, and the external cooling water flows through the cooling water flow channel to cool the bearing seat 3.
[0032] This embodiment adds an oil cooling system based on the above. Figure 2 As shown, the bearing seat 3 is provided with an oil passageway independent of the cooling water flow channel, the oil passageway forms an oil inlet at the upper end of the bearing seat 3 and an oil outlet 7 at the lower end of the bearing seat, wherein an oil guide pipe 5 is provided at the oil inlet for guiding cold machine oil to spray lubricate the bearing.
[0033] An oil tank 15 is provided outside the bearing seat 3, and the oil tank 15 is provided with an oil supply system connected with the oil guide pipe and the oil outlet hole on the bearing seat 3. Since there are two bearing seats on the main shaft in this embodiment, the oil tank 15 in this embodiment is provided with two independent oil supply systems.
