Highlights of Self Loading Transit Mixer

1. The Highlights Of Self Loading Transit Mixer Abstract: Self loading transit mixer overcomes the shortcoming of the traditional concrete trucks, realizing self loading, mixing, transport and discharging. Its self weighing ensures the accurate ratio, thus bringing quality concrete for various small projects such as road construction. A Versatile Self Loading Transit Mixer As we all know, concrete mixer trucks are indispensable in all types of projects. During The Transportation, It Keeps Rotating To Avoid The Segregation And Initial Setting. When The Concrete Segregates, The Cohesive Force Of The Mortar Will Decrease, So The Strength Will Also Decrease To a Certain Extent. And when the concrete initially sets, it will change from soft to hard. However, most concrete mixer trucks do not have a water tank and a water pump, which is not convenient to use in some occasions. In addition, it needs a loader to feed or work for the concrete batching plant.

2. In order to solve these problems, haomei machinery develops a self loading transit mixer, having self loading, weighing, mixing, transport and discharging,etc. It integrates the functions of three kinds of machines: The loader, the concrete mixer and the concrete mixer truck. Therefore, its working efficiency is much higher than that of the traditional concrete mixer truck. Since the self loading concrete mixer has a relatively high degree of automation and industrial scale, the concrete quality can meets the required standards. And it has a water tank and a water pump, which can start mixing anytime and any places where there is water. The self loading concrete mixer machine is of simple operation. Two persons cooperate can finish work together. The learning of the self loading concrete mixer machine is very easy, and ordinary people can get started after a few hours of learning. Compared with the traditional match of loader, concrete mixer and concrete mixer truck, plus generator sets and waterwheels and other machinery, the self loading concrete mixer truck is cheaper and more cost-effective while meeting the same concrete need. Moreover, it has a smaller body, so it is more suitable for driving in narrow places.

3. Self Loading Concrete Machine for Road Construction Road construction is an important part for the remote or mountainous areas, which will not only facilitate their life and travel, but also contributes to developing tourism and other economies. But since the rural projects always face to a lack of workforce, a highly automatic construction machine is needed. At present, there are three ways to get concrete: Buying commercial concrete, concrete mixer or manual operation. As we know, for small projects, buying commercial concrete will bring exacerbate budgetary constraints. The using of concrete mix and manual operation is of low efficiency. That’s why the self loading concrete machine is popular in rural road construction. The self loading concrete machine is of self loading, weighing, mixing, transport and discharging. It can discharge with 270 degrees over driving. More importantly, its mixing quality can fully meet the road construction. Under normal circumstances, c25 concrete can be used in rural road construction, but if it is a section where large vehicles are allowed to pass, c30 and c35 concrete with higher hardness is required. The thickness of rural roads is basically 20 cm, and 0.6 cubic meters of concrete is needed to build a one-meter road. A mini self loading

It can have a strict control of each material according to the concrete ratio. In addition, it has a strong mixing technology, which ensure the quality of concrete. The mini self loading concrete mixer enable the construction contractors get concrete at the price of raw material. Its price is one-fourth of the commercial concrete price. Its efficiency is several times that of a concrete mixer. How Does Self Loading Transit Mixer Realize Self Weighing The self loading transit mixer is a kind of equipment that combines the functions of a concrete truck and a concrete batching plant. It can realize self loading, weighing, mixing, transportation and on-site discharge. How to realize the accurate control of each material’s weight? Its self weighing system is based on matlab/simulink platform, including communication module, filter module, ratio module, clear module and control module. The communication module is used for signal communication between devices, the sampling period is 10 ms; the filter module processes the input weighing system signals, and a discrete filter is designed to filter out drum vibration and impact. The proportioning module calculates the proportion of materials mi; the zeroing module calculate the the remaining weight me; the control module adopts a segmented control strategy to control the solenoid valve action according to the

This test includes two parts: Adding water and adding sand. After calculation, it is determined that 1 m3 of c15 concrete needs 115 kg of water when the sand humidity is 10%. It is determined that 0.8 m3 of c30 concrete requires 567 kg of sand when the sand humidity is 10%. After the driver inputs the parameters and clears them to zero, the water pump automatically adds water, the weighing system weight increases approximately linearly. When the remaining weight reaches 0, the water addition process ends and the water valve automatically closes. Press the p2 reset button, the driver manually opens the bucket door. When the weight reaches the first threshold, part of the bucket is closed. It can be clearly seen that the material addition becomes slower and the slope decreases. When the remaining weight reaches the estimated value, the bucket valve closes and the material addition ends. Through the trial on the construction site, Haomei self loading concrete mixer can realize automatic and accurate control. The accuracy of adding solid materials is within ±5 kg, and the accuracy of water supply is within ±5 kg, which is highly feasible.
