Seven Precautions for Operation of Self feeding Mixer
1、 The automatic feeding mixer shall be parked on the flat ground, and the bucket shall be placed on the ground. When the engine is off, pull the operating handle of the working device repeatedly to ensure that each hydraulic cylinder is in a pressure free rest state. If the automatic feeding mixer can only stop on the ramp, the tire shall be firmly padded.
2、 Before loading from the charging mixer truck, the remaining water and sundries in the mixing tank shall be drained. Keep rotating during transportation to prevent concrete segregation. Before the loading mixer truck arrives at the construction site and discharges materials, the mixing tank shall be rotated for 1-2 minutes at the speed of 14-18 revolutions per minute, and then the reverse unloading shall be carried out. Before reversing, the mixing tank shall be stopped stably.
3、 If the ambient temperature is higher than 25 ℃, the duration from loading, transportation to unloading shall not exceed 60 minutes; If the ambient temperature is below 25 ℃, the above time shall not exceed 90 minutes.
4、 After unloading at the construction site, the hose attached to the truck from the loading mixer shall be used to flush the feed hopper, discharge hopper, discharge chute, etc., to remove the sludge and concrete adhering to the vehicle body. On the way back to the mixing plant, 150L - 200L water shall be injected into the mixing tank to clean the concrete residue bonded by the mixing tank wall and blades.
5、 At the end of each day's work, the driver shall be responsible for injecting clean water into the mixing tank and rotating it for 5-10 minutes at the speed of 14-18 revolutions per minute, and then draining the water to ensure the cleanness of the mixing tank. When cleaning all parts of the mixing tank with high-pressure water, avoid instruments, control rods and other parts.
6、 When removing the residual concrete slag inside and outside the mixing tank, and when the machine maintenance personnel enter the mixing tank for maintenance and repair welding, the engine of the mixing truck shall be shut down first to make the mixing tank stop completely. During the working period when the machine maintenance personnel enter the mixing tank, it is necessary to ensure that the mixing tank is well ventilated and free of combustible gas and harmful dust. When electric tools are used in the mixing tank, the operators shall have good insulation protection.
7、 When working from the charging mixer truck, it is not allowed to put your hand into the rotating mixing tank, and it is not allowed to put your hand into the connection part of the main discharge chute and the extended discharge chute, so as to avoid accidents.
