The embodiment of the application solves the problems of overhigh height and unstable center of gravity of the existing large and medium-sized vertical sand mill by providing the novel lifting structure for the vertical sand mill.
In order to achieve the purpose in the prior art, the utility model adopts the following technical scheme:
the utility model provides a novel elevation structure for vertical sand mill, includes the frame, is equipped with in this frame: the grinding machine comprises a bearing seat, a main motor, a lifting device and a grinding rotor, wherein a main shaft and a grinding rotor are arranged in the bearing seat; and the grinding barrel is detachably connected with the bearing seat, the grinding barrel is arranged on the ground, and the bottom surface of the grinding barrel is provided with a roller.
Further, the lifting device is a hydraulic oil cylinder.
Further, the rack is further provided with a top plate, the bearing seat and the main motor are arranged on the top plate, and the lifting device drives the top plate to lift.
Further, the bottom of the grinding barrel is provided with a lower cover plate.
Further, the rack is also provided with a guide pillar, and the top plate ascends and descends along the guide pillar.
Compared with the prior art, the utility model has the beneficial effects that: the grinding barrel is arranged on the ground, so that the whole height of the grinding machine is reduced, the grinding machine can be in a reduced state in manufacturing, transporting, entering and exiting workshops and working states, the height limit requirements of the transporting process and the entering and exiting workshops are facilitated, the gravity center is low, and the safety requirements of manufacturing, transporting and using are met.
