fully automated Mobile self-loading concrete truck mixers Automatic mobile self loading concrete mixer
Automatic mobile self-contained concrete mixer by the car chassis and concrete mixing transport equipment. China's production of concrete mixer truck chassis used by the vehicle manufacturers to provide more than two types of general chassis. Its special institutions include power take-off, mixing cylinder front and rear bracket, reducer, hydraulic system, mixing tube, control mechanism, cleaning system. The working principle is through the power plant to remove the power of the car chassis and drive the hydraulic system variable pump, the mechanical energy into hydraulic power can be passed to the quantitative motor, the motor and then drive the reducer, driven by the reducer mixing device, the concrete mixing The
1, the hydraulic system pressure should be in accordance with the provisions of the instructions, not free to adjust. Hydraulic oil oil and oil should meet the original requirements.
2, before mixing the mixer, you should first clean the remaining pool of water and debris. In the transport process to keep the rotation, to prevent the separation of concrete. Before the mixer reaches the site and unloading, the mixer should be rotated at 14-18 revolutions per minute for 1-2 minutes at full speed before reversing the discharge. Before reversing, the stirrer should be stopped without turning.
3, the ambient temperature is higher than +25 degrees Celsius, from the charge, transport, to discharge the duration of not more than 60 minutes, the ambient temperature below 25 degrees Celsius, the time should not exceed 90 minutes.
4, winter construction, should be done: before the start of the water is checked whether the ice; get off work properly removed from the mixing tank and the water supply system residual water, close the pump switch, the control handle placed in the "stop" position.
5, in the construction site after the discharge is completed, should immediately use the mixer with the hose rinse into the hopper, hopper, unloading chute, etc., to remove the sludge and concrete attached to the body everywhere. On the way back to the mixing station, pour 150 --- 200L of water into the mixing cylinder to clean the cylinder residue and the concrete residue.
6, after the end of the work every day, the driver should be responsible for the injection of water into the mixing tube and high-speed (14-18 r / min) rotation 5-10 minutes, and then drain the water to ensure clean cylinder. Use high-pressure water to clean the various parts of the mixing cylinder, should pay attention to avoid the instrument and joystick and other parts. The distance between the pressure water nozzle and the body paint surface shall not be less than 40 cm.
7, remove the mixing tank inside and outside the accumulation of dirt and residual concrete slag, as well as the crew into the cylinder for maintenance and welding operations, the need to first turn off the car engine, so that the mixing cylinder completely stop rotation. During the work of the crew into the cylinder, it is necessary to ensure that the ventilation is well ventilated, fresh air, no gas and harmful dust, adequate oxygen supply (no use of pure oxygen). When operating in a cylinder with a power tool, the operator must have good insulation protection.
8 automatic loading and unloading mobile concrete mixer, is a combination of concrete truck and concrete mixing station function as a whole, set the concrete charge, measurement, mixing, out in one, and can achieve concrete transport and on-site concrete construction operations Mixing equipment, the equipment fast and efficient, greatly improve the production efficiency and reduce the production time and cost. Applicable to all kinds of special environment, crowded urban areas and remote areas of concrete construction.
