1. Allow the mixing tank to run at full speed for a few minutes before unloading
High speed rotation allows the concrete to be fully mixed to prevent solidification, and some water can be added to discharge the material.
2. Wet the chute of the discharge hopper before discharging
Try to park the vehicle on a flat surface for discharge, and wet the discharge chute before discharge to prevent concrete from sticking to the chute, which is easy to clean.
3. Don't be careless when unloading
When discharging, keep an eye on the entire process to prevent the discharge worker from operating the discharge lever recklessly. Every time the can is rotated in the middle position, it is easy to stop and protect the reducer and tray.
4. Rinse the mixing tank thoroughly
The self feeding mixing tank must be carefully rinsed clean, repeatedly rotating and reversing the tank body to ensure that there are no dead corners in the water for cleaning, and repeatedly adding water for cleaning to maintain the cleanliness of the tank interior and no concrete residue.
In addition, pay attention to cleanliness during loading, such as:
1. Reverse the mixing drum before loading
The mixer truck is usually parked outdoors. Before loading, the accumulated water and debris such as leaves in the tank should be discharged to avoid affecting the quality of the concrete.
2. Remember to flush the feed hopper after loading
After washing, it is necessary to turn off the air inlet of the water tank and open the air outlet of the water tank to exhaust the gas. This is because under pressure, areas where the water pipe is not properly connected can easily leak water, affecting the safety of other vehicles. Check the tires again for debris such as stones and nails, and use tools to clean them in a timely manner, as the area where the tires come into contact with the ground during parking cannot be detected.
When removing dirt and residual concrete debris inside and outside the mixing drum, as well as when mechanical maintenance personnel enter the mixing line inside the drum for automatic feeding, what should be paid attention to during maintenance and welding operations? The car engine should be turned off first to completely stop the mixing drum from rotating.
During the period when maintenance personnel enter the mixing drum to work, it is necessary to ensure good ventilation, fresh air, no natural gases or harmful dust, and sufficient oxygen supply inside the mixing drum. When using electric tools inside the cylinder, operators should have good insulation protection.
When working, do not extend your hands into the rotating mixing drum, and do not extend your hands into the connection between the main discharge chute and the extended discharge chute to avoid accidents.
The above is the summary by the editor that these tasks should be done well when fully automatic mixer trucks discharge materials!, Please follow the rules and regulations when using and ensure safe production. For more related content, come to our website Consultation and understanding!
