Concrete mixer inside tank car of mixing station

We have a lot of knowledge in our daily life, and it is very difficult for friends who are eager for knowledge to know a little knowledge every day. So, do you know much about cars? I think in our daily life, besides family cars, there are also some industrial travel tools. Today, Auto Xiaobian will briefly introduce the interior of the tanker in the mixing station for friends.

Inside the tank car of the mixing station: concrete mixer

Concrete mixer truck is a special truck used to transport building concrete. Because of its shape, it is usually called a snail car. These trucks are basically equipped with cylindrical mixing barrels to transport the mixed concrete. During transportation, the mixing drum will always keep running to ensure that the transported concrete will not solidify. After concrete is transported, the interior of the mixing drum is usually cleaned with water to prevent hardened concrete from occupying empty space, thus reducing the volume of the mixing drum.

Interior decoration of tank car in mixing station: composition

It consists of an automobile chassis, a mixing drum, a transmission system, a water supply device, a full-power power take-off, front and rear brackets of the mixing drum, a reducer, a hydraulic transmission system, a feeding and discharging system, an operating mechanism and the like. Due to technical bottleneck, the tank capacity of domestic mixer truck is 3 m&; sup 3-8m & amp； Sup3 uses domestic four-piece set, 8m &；; Most of the four volumes used on sup3 contain imported parts.

The mixer truck consists of secondary chassis, transmission system, hydraulic system, frame, mixing tank, feeding and discharging device, water supply system, operating system, ladder, etc. The front end of the mixing tank is connected with the reducer and installed in the foreground of the frame, and the back end is supported by two supporting wheels installed in the background of the frame through the raceway.

abstract

The key of special mechanism includes power take-off, front and rear supports of mixing drum, reducer, hydraulic system, mixing drum, operating mechanism, cleaning system and so on. Its working principle: the power of the automobile chassis is taken out by the power take-off, which drives the variable pump of the hydraulic system, converts mechanical energy into hydraulic energy and transmits it to the quantitative motor, which then drives the reducer, which then drives the mixing device to mix the concrete evenly.

Power output equipment

Domestic concrete mixer adopts the power take-off of truck main engine. The function of the power take-off is to take out the power of the engine by operating the power take-off switch and drive the mixing drum through the hydraulic system. The mixing drum rotates forward in the process of feeding and transportation, which is convenient for concrete feeding and mixing, and rotates backward when discharging, and the power connection with the engine is cut off after the work.

hydraulic pressure system

The engine power (mostly the rear full-function power take-off) taken out by the power take-off is converted into hydraulic energy (displacement and pressure), and then the motor outputs it as mechanical energy (rotational speed and torque) to provide power for the operation of the mixing drum.

reductant

The output speed of the motor in the hydraulic system is decelerated and transmitted to the mixing drum.

Control mechanism

A. Adjust the rotating direction of the mixing drum to make it rotate forward in the process of feeding and conveying and backward in the process of discharging.

B. adjust the rotating speed of the mixing drum.

mixing equipment

It consists of a mixing drum and its paving support parts. Mixing drum is a container for loading concrete. Adopt high-quality wear-resistant steel plate to automatically load and unload concrete. Its inner wall is welded with spiral blades with special shapes. When working, the concrete moves along the spiral direction of the blade and is mixed and stirred in the process of continuous lifting and overturning. In the process of feeding and transportation, the mixing drum rotates forward and the concrete moves inward along the blades. When discharging, the mixing drum rotates reversely, and the concrete is discharged along the blades. The operation of the mixing drum is guaranteed by the hydraulic drive device. The loading capacity is 3~6 cubic meters. Most concrete mixers use automobile engine to drive hydraulic pump through power output shaft, and then high-pressure oil drives hydraulic motor to drive mixing drum, while vehicle-mounted paving diesel engine drives hydraulic pump to drive hydraulic motor. Blades are the key components in the mixing device. Damage or serious wear will affect the uneven mixing of concrete. In addition, if the angle of the blades is unreasonable, the concrete may separate.

scavenger system

The main function of the cleaning system is to clean the mixing drum, and sometimes it is also used to stir dry materials during transportation. The cleaning system also cools the hydraulic system.

locking device

The fully enclosed device adopts rotary sealing technology to seal the entrance and exit of the mixer truck, which solves a series of problems existing in the traditional mixer truck, such as water evaporation, mortar stratification, concrete scattering and safe driving.

After reading the introduction of the car system, is it necessary for friends to know about the interior of the tank car in the mixing station? Bian Xiao believes that these knowledge partners still need to understand the content well. After all, knowledge is very important to each of us. Besides, if we know more, we may be able to use it one day. Finally, I hope the profile of Bianxiao Automobile can solve the problem for my friends.
