1、 Purpose and Characteristics
This machine belongs to the double horizontal axis forced mixing fixed concrete mixer, which can mix plastic and semi dry hard concrete with very uniform mixing, high productivity, good quality, and low cost. Suitable for underground mines, general construction sites, roads, and bridge engineering.
2、 Structure Introduction
The main components of the mixer include: mixing device, mixing transmission system, feeding and discharging system, etc.The mixing mechanism consists of a mixing drum, a mixing shaft, a mixing arm, mixing blades, and side blades. The mixing drum is equipped with two horizontally arranged mixing shafts, each with mixing blades. Side blades are installed on the mixing arms near both ends of the mixing drum, which can scrape off the concrete on the end face and change the flow direction of the concrete.
The transmission system consists of an electric motor, pulleys, gearbox, etc. The electric motor drives the secondary gear reducer through a pulley, and the two shafts of the reducer are driven by two pairs of open gear pairs consisting of two open small gears and two open large gears.
3. Loading and unloading system
The feeding system consists of a hoisting mechanism, a feeding rack, a hopper, a feeding hopper, pulleys, etc. The inclined angle of the feeding rack is 60 °, and the feeding guide rail (discharging guide rail) is made of channel steel. The upper roller of the roller is placed on the inner side of the channel steel, and the lower roller is placed on the outer side of the channel steel to ensure the safe and stable loading and unloading of the hopper. The motor drives the drum to rotate through the gearbox, and the steel wire rope pulls the hopper up along the feeding rack track through the pulley. When it reaches a certain height, a pair of rollers on the bottom hopper door enter the horizontal channel of the feeding rack, and the hopper door automatically opens. The material is manually discharged into the bucket through the feeding hopper. Composed of unloading doors, operating handles, and other mechanisms. The discharge door is installed at the bottom of the mixing tank, and can be rotated around a horizontal axis by operating the handle to achieve the purpose of opening and closing. The discharge can be adjusted. The position of the sealing strips on both sides ensures the sealing of the discharge door.Main Technical Parameters:
