Vertical-type oblique-axis concrete mixer

Abstract

The invention discloses a vertical-type oblique-axis concrete mixer. The vertical-type oblique-axis concrete mixer comprises a machine frame, a revolving drum drive motor, a cross beam, a stirring drive motor and a material lifting drive motor. A slewing bearing is arranged inside the machine frame, and a mixing drum is arranged inside the slewing bearing. An outer gear ring is arranged on the outer side wall of the mixing drum. The revolving drum drive motor is fixed to the machine frame, and a spindle of the revolving drum drive motor is connected with a driving gear engaged with the outer gear ring. The cross beam is provided with a stirring support and a material lifting support. A stirrer is assembled inside the stirring support in a rotating mode, and a material lifter is assembled inside the material lifting support in a rotating mode. One end of the stirrer and one end of the material lifter stretch into the mixing drum. The stirring drive motor is fixed to the stirring support, and a spindle of the stirring drive motor is connected with the stirrer. The material lifting drive motor is fixed to the material lifting support, and a spindle of the material lifting drive motor is connected with the material lifter. The vertical-type oblique-axis concrete mixer is simple in overall structure, easy to implement and capable of effectively improving the stirring quality and stirring efficiency of mixtures.

Description

technical field [0001] The invention belongs to a mixing device, in particular to a vertical inclined shaft concrete mixer. Background technique [0002] As a common mixer, the forced mixer has the advantages of strong mixing effect and wide application range of concrete. According to the structure, the forced mixer can be divided into two categories: vertical mixer and horizontal mixer. The shaft end of the vertical mixer does not have the problem of sealing and slurry leakage, and has high reliability, so it has been widely promoted and applied. When the existing vertical mixer is working, the mixing drum is fixed, and the mixing tool in the mixing drum mainly pushes the mixture to move in the circumferential direction to achieve uniform mixing of the mixture. With the large-scale development of the mixing drum, the size of the mixing tool is also increasing. Since the linear velocity near the outermost area of ​​the mixing tool is relatively high, the mixture is prone to...

Problems solved by technology

With the large-scale development of the mixing drum, the size of the mixing tool is also increasing. Since the linear velocity near the outermost area of ​​the mixing tool is relatively high, the mixture is prone to segregation when it is subjected to a large centrifugal force in this area; In addition, when the mixing tool rotates, the mixture only moves on the same plane, and the mixture will not be turned up and down. This kind of mixing method has low mixing efficiency in the central area of ​​the mixing drum, which not only prolongs the overall mixing time, but also makes the concrete mix evenly. bad sex
