Xiagong Chusheng concrete mixer performance
Section 1 Overall Vehicle Construction <br><br> The following figure shows a schematic diagram of a standard 6X4 concrete mixer truck.
The mixing truck is mainly composed of a chassis, a hydraulic transmission system, a mixing drum, an in-out material feeding device and other structural parts. The chassis and the hydraulic transmission system are the main purchased parts. The mixing drum, the in-feed and discharge equipment are the main self-made parts. The specific composition of a concrete mixer truck can be seen at a glance with reference to the structural diagram of the mixer truck. The side guards and the rear guards are all required by the national automobile mandatory standards. The main purpose of the side protection device is to prevent pedestrians from being caught under the wheel and cause casualties. The main purpose of the rear protection device is to prevent the rear-end car from crashing into the rear of the mixing truck causing casualties. The mixing truck should have both installed. Kinds of protective devices.
The quality of the mixer is mainly determined by the chassis, pump, motor, reducer, mixer, etc. The three large-scale mixers produced by XCMG Chusheng are made from imported Rexroth components from Germany, Eaton from the USA, and Ziefu from Germany. The mixing drums and blades are made of manganese steel. The weight of the vehicle is less than that of carbon steel and the strength is higher than that of carbon steel. Plates, better durability.
Chassis of the second quarter
Mixer trucks are generally used after the second type of special chassis for stereotyped production is installed and installed. The performance, quality, and price of the chassis have a great influence on the vehicle of the mixer truck. Therefore, more attention should be paid to the chassis.
The chassis is generally composed of an engine, a clutch, a transmission, a transmission shaft, a steering axle, a driving axle, a frame, a tire, an operating system, a suspension system, and an electrical system.
In the selection of the chassis, the focus is mainly on the chassis engine power and torque, fuel consumption, tires, beams, driving comfort and emission standards.
Section 3 Hydraulic Transmission Components The concrete mixer truck has high requirements for the quality and reliability of the hydraulic transmission components. If the failure occurs during construction, the consequences can be disastrous. At present, there are two configurations on the hydraulic drive system market:
XCMG ChuSheng Mixer All the purchased parts in the system are made of internationally renowned brands such as hydraulic oil pumps and hydraulic motors produced by German Rexroth, and the reducers are produced by German ZF and other companies, in terms of quality, reliability, etc. All aspects are guaranteed.
Section IV Mixer
The main influence on the performance of the mixer drum is the arrangement of the stirring blades. There are two schools of mixing blades on the market today. One is Japanese and the other is European. The Japanese school is characterized by a large pitch, a small number of laps, and a high discharge speed. The fact that the European school has the opposite is that the pitch is small, the number of turns is large, and the discharging speed is relatively slow, but the blade wear is relatively small. In order to save fuel, the user generally hopes that the unloading speed can be swift, and can keep up with the pump speed of the pump truck or the tow pump. The XCMG Chu Sheng Mixer drew the advantages of the two. The blade was a double logarithmic variable pitch spiral with a pitch between the two. The variable pitch design (especially at the nozzle) ensured a faster idling discharge. Speed ​​to meet pumping needs of pump trucks and trailers.
The material of the mixing drum and the stirring blade is also a concern of the user, and the 16Mn plate is widely used at present. The application of new high wear-resistant alloy steel materials is also gradually increasing.
Section V Others In addition to the above four main components, other structural components include: subframe, front desk, backstage, feed hopper, hopper, discharge chute, lengthened chute, tire cover, ladder , side protection devices, rear protection devices, control systems, water supply systems, electrical systems, etc.

Twisted Paper Rope handle making machine,
This is a good machine for making twisted Paper Handle.It pastes the twisted paper rope and paper strap together and cut off them for separate handles.It is running stably and fast with hot melt glue application. The handle size can be customized according to customers`request and one machine can make several different handle sizes.
Normally, one 5 or 10 meter long production line is followed at the end of this machine so that the workers can put the ready made handles on the paper bags on site when the ready made handles coming out from the machine
