Japan R & D Pocket Life Detector
Concrete mixer (cement mixer) is a special truck used to transport concrete for construction; because of its shape, it is often called a snail car. These trucks are equipped with cylindrical mixing drums to carry the mixed concrete. During the transportation process, the mixing drum will always be kept rotating to ensure that the concrete carried will not set. After the concrete is transported, the inside of the mixing drum is usually washed with water to prevent the hardened concrete from taking up space and making the volume of the mixing drum less and less.

The instrument is very small, like a cigarette box, and weighs 950 grams. Based on the principle of electromagnetic radiation, firefighters take it in their hands and can easily detect whether there is a range of 6 to 12 meters. The existence of life can also be detected as the existence of plural lives, that is, one or several people are trapped in the depravity and failure. The instrument has a display screen, just like a cell phone, with one or several red symbols on the screen, which proves that there is life underground and can show the horizontal distance between the trapped and the rescuer in the rubble. , the depth of the ground and the state of orientation, etc. The search limit is 12 meters. In the rescue process, the use of this instrument can confirm the place of life within three minutes. At present, the development unit has produced 10 prototypes. In 2006, it will be mass produced and sold.
It is composed of automobile chassis, mixing drum, transmission system, water supply device, full power take-off, front and rear brackets of the mixing drum, reducer, hydraulic transmission system, feeding and discharging system, control mechanism and other parts. Due to technical bottlenecks, the domestic mixer trucks with a volume of 3m³-8m³ adopt the four major domestic products, and most of the four components with a volume above 8m³ are imported components.
Composition of mixer truck: second-class chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, control system, human ladder and other parts. The front end of the mixing tank and the reducer are connected and installed on the front of the rack, and the rear end is supported by the two supporting wheels installed on the back of the rack through the raceway.
