Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in figures 1 and 2, the lifting vertical shaft vibration stirrer is cylindrical above a body, a hemispherical stirring barrel is arranged below the body, a feeding port 9 is arranged above the body, and a discharging port 1 is arranged below the hemispherical stirring barrel; the stirring mechanism in the body is vertically arranged with the lifting mechanism;
elevating system is including setting up the power 12 in the body top, power 12 with electric hollow telescopic handle 10 connection of electric lines, electric hollow telescopic handle 10 below joint support pole 8, the guide rail 6 sliding connection on slider and the body inner wall is passed through at 8 both ends of bracing piece, 6 strokes of guide rail end is provided with stopper 5, can guarantee the stability of pneumatic cylinder extreme lower position.
