The self loading mixer is a special truck for transporting construction concrete; Because of its shape, it is often called a snail truck. The truck uses a cylindrical mixing drum to transport the mixed concrete. During transportation, the mixing drum shall be kept rotating to ensure that the concrete will not set. After the concrete is transported, the interior of the mixing drum is usually washed with water to prevent the hardened concrete from occupying space and reduce the volume of the mixing drum.
The mixing tank is the core component of the mixer truck, with high technical content. Because its technical content will directly affect the quality of concrete, the design of mixing tank requires high precision and small tolerance range. The blades in the mixing tank adopt double logarithmic spiral design, which can only be used after actual test and simulation correction.
The blades in the mixing tank can improve the discharge performance of concrete. There are holes on the blades in front of the discharge port, which can reduce the bonding performance of concrete to the blades and improve the uniformity of discharge. The sliding angle of the entire blade from the bottom of the mixing tank is continuously increased to ensure that the blade can fully mix the concrete and reduce the residual rate.
The mixing tank is generally made of wear-resistant high-strength steel plate. After the mixing tank is formed, remove the inner support and weld the blades. The blade is generally made of high wear-resistant steel, and the mixing quality is perfectly combined with the discharge speed. The welding process adopts carbon oxide protective film. After the fabrication of the stirring tank, shot blasting is carried out to eliminate the stress generated during welding and fabrication and improve the adhesion of the coating.
In addition, more attention自上料搅拌车 should be paid to the daily self inspection of vehicles, such as driving habits, driving, starting, braking, etc; Vehicle chassis, axle and positioning, whether the center of gravity is offset, etc. Anti freezing measures for hydraulic parts in winter; Tank work; Remote throttle oil supply operation; Tire: tire pressure measurement, load-bearing measurement of fully loaded tires; Focus on the sponge section of the tire, and the wear condition.
In the process of use, the mixer shall be started as smoothly as possible, run at a slow and uniform speed, and frequently check the use of hydraulic system pipelines and bearing components. It is recommended to use the same brand of oil products, and the standards of oil products produced by different manufacturers are different. After mixing, the lubricating grease is difficult to clean and block, which increases the risk of failure. It operates stably and is maintained frequently and checked carefully.
