Concrete mixer

Abstract

The invention discloses a concrete mixer. The concrete mixer comprises a support, a mixing drum and motors. The concrete mixer further comprises wheels, supporting legs, a lifting device, a first belt pulley, a cavity, a belt, supporting columns, a second belt pulley, a fixed platform, mixing blades, a feeding opening, a first mixing shaft, a sealing cover, bearings, a discharging opening, grinding balls, a second mixing shaft and a rough plate. The supporting legs with the wheels are arranged on the lower portion of the support. The mixing drum is disposed on the support. The first mixing shaft with the mixing blades is arranged in the center of the mixing drum. The two ends, stretching out of the mixing drum, of the first mixing shaft are fixed to the supporting columns through the bearings respectively. One end of the first mixing shaft is inserted in the fixed platform. The second belt pulley is arranged at the end, stretching out of the fixed platform, of the first mixing shaft. The second belt pulley is connected with the first belt pulley through the belt, and the first belt pulley is arranged on the motor in the cavity. The second mixing shaft provided with the grinding balls and connected with the corresponding motor is further arranged on the lower portion of the mixing drum. The concrete mixer is high in mixing efficiency and capable of grinding large-grain concrete.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a concrete mixer. Background technique [0002] Mixer is a very important type of construction machinery, and its working efficiency directly determines the construction efficiency of the entire construction site. That is, once it cannot mix qualified concrete at the fastest speed, the entire construction site cannot work efficiently. However, most of the current concrete mixers use a rotating mixing bucket, and the concrete is stirred in the mixing bucket. Such a mixer takes a long time, and larger granular impurities are easy to settle to the bottom of the mixer, greatly Reduced the quality of the concrete, not practical enough. Contents of the invention [0003] The invention provides a concrete mixer, which is mainly used for mixing concrete. The invention can not only mix the concrete efficiently, but also grind the impurities with larger particles in the co...
