Working steps of extruding curb machine:

  1. Add diesel and water to the diesel engine. (The machine has been oiled before leaving the factory)
  2. Move the machine to the construction location.
  3. Start the diesel engine with a rocker.
  4. Adjust the hydraulic handle so that the bottom of the mold of the machine fits the ground. Make the front of the machine 1 cm higher than the rear.
  5. A worker uses a drawbar to control the direction of travel of the machine in front.
  6. Continuously put the mixed concrete material (or the heated asphalt sand material) into the feeding hopper.
    Note: Before putting in the tar sand, it is necessary to spray the separator on the screw shaft and the blade (diluted by diesel engine + water) to prevent the asphalt material from sticking to the shaft and the blade, affecting the discharge and walking.
  7. Cleaning with the machine: Check the finished product in time to meet the engineering requirements, and timely clean up the spilled material during the feeding process. When encountering the rapids, partially shovel the water inlet.
