The extruder uses the basic principle of rotary pressure transfer. The hydraulic oil pump converts the chemical energy of the diesel engine into hydraulic function, and the oil motor drives the stirring dragon to rotate according to the low speed gear and large torque distance, and transfers the concrete mixing material entering the mixing bin to the forming cavity; on the other hand, according to the oil motor to push the vibrator, High-frequency vibration is generated for the stirring material in the molding cavity. Under the overall function of the extruding pressure of the stirring dragon and the vibration force of the vibrator, the stirring material in the forming cavity fills the forming cavity and reaches the set density level. Under the action of the radial resistance of the mixing dragon, the side wall extruder moves forward with the dense concrete as the supporting point, and the hot pressing continues to produce a concrete side wall with a trapezoidal cross-sectional shape. What is the principle of the extruder? The mixing material enters into the auger evenly, the side wall extruder moves at a uniform speed, and the hot pressing also produces a concrete side wall with a set compaction degree; the mixing material enters the hopper intermittently, and the side wall extruder The forward travel rate of is a variable value; when the mix is ​​terminated, the forward travel rate of the sidewall extruder is zero. That is, the forward speed of the side wall extruder is automatically adjusted without control, and the primary condition for adjustment is that the mixing material in the forming cavity achieves the set density level. The compaction level of the concrete side walls can be set as required. The primary condition for the sidewall extruder to move forward is that the fulcrum force of the agitated material in the forming cavity is equivalent to the sum of various frictional resistances of the equipment moving forward. The relative height of the point can change the frictional resistance between the mixture and the template in the forming cavity. The frictional resistance is the key component of the total forward pressure. The total frictional resistance decreases and the density of the mixture decreases; on the contrary, the density of the mixture increases. .
