Function of mixing arm of concrete mixer

The mixing arm is one of the components of the concrete mixer. Many users do not understand it after purchase and installation. They are curious about how the mixing arm is used and what the functions of the mixing arm are. Let's share the functions of the mixing arm of the concrete mixer. Let's have a look.

 

Function of mixing arm of concrete mixer:

 

The forced concrete mixer includes a mixing drum, which is equipped with a mixing shaft, the mixing shaft at both ends of the mixing drum is equipped with a side arm for cleaning the end wall surface, a group of spiral arranged mixing arms are installed on both sides of the midpoint of the mixing shaft between the two arms, and the two groups of mixing arms are arranged axially from the end arm to the middle arm, The arrangement in the rotation direction is evenly distributed from the end arm to the middle arm, the top of each mixing arm is provided with fixed mixing blades, and the arrangement of both arms in the rotation direction lags behind the end arms of the mixing arm on the same side.

 

The mixing arm itself is divided into side mixing arm (positive and negative), middle mixing arm (positive and negative). Below the mixing arm is the connecting tile seat, which is connected with 4 sets of high-strength bolts of the mixing arm. Above is the installed wear-resistant mixing blade, and 2 sets of high-strength bolts for connecting the mixing blade. In addition, some manufacturers design a mixing square stick shaft rotating ring, which is installed between the mixing arms in two ways: fixed and rotating.

 

According to the utility model, the position of the side arm in the rotation direction of the overall mixing arm layout is retreated to make it lag behind the end arm of the mixing arm group on the same side. In this way, during actual work, the working resistance of the side arm is small and there is no cutting and grinding between the side arm and the mixing cylinder, so as to improve the durability of the side arm and reduce the driving force required by the mixing shaft. Therefore, a low-power motor can be assembled to reduce the manufacturing cost, The energy consumption is reduced accordingly.
