Mixer of literacy

Concrete mixer mainly consists of the components of the chassis and upload simply can be divided into: chassis systems, hydraulic transmission, mixing tank, discharging systems, cleaning systems, sub-frame, steering system, roller system, feeding system , the ten components of the circuit system.

1, chassis systems: The main part of the mixer, the whole function is to transport concrete mixer from the chassis to achieve.

2, hydraulic drive system: the engine power by removing the power take off, into hydraulic energy (displacement and stress), and then the motor output mechanical energy (speed and torque), provide the impetus for mixing drum rotates.

  3, stirred tank: mixing tube is a key component of the mixer truck is stored in concrete containers, to prevent concrete curing, segregation plays a decisive role. Tank internal vane, mainly from the mixing and guide material effect.

  4, the feeding system: mainly by the main chute, deputy discharge chute, locking lever, etc., from the role of deputy main discharge chute to extend the length of the slot.

  5, the cleaning system: cleaning system consists of a pressure tank, water gun, water pipes, valves and other components. Using pressure water supply, the main role is to rinse after Bahrain feed hopper and a complete wash after mixing tube feeding, discharge chute to prevent concrete bonding.

  6, sub-frame: mixer sub-frame is the main load-bearing part, almost all of the load job to support it then passed through the chassis. Subframe also help ease the bumpy road, slow down the formation of shock loads role. Entire sub-frame from the main beam, front bracket, backstage support frame components.

7, the operating system: the operating system by the controller, the linkage shafts, shaft and connecting rod bodies, mainly to control the speed and direction of rotation of the mixing tube.

8, roller system: mixing tank connected to the rear of the sub-frame parts, mainly from the supporting role of the drum body.

9, the feed system: the composition of the feed hopper with the holder, into the hopper impact wear due to greater abrasion resistance material requirements, mainly from the stent to reduce the force of the impact.

10, a circuit system: mainly refers to the entire circuit mixer, including the vehicle's tail lights, side marker lights, showing porch lamp, cooling fan motor.

Mixer mixing function principle: power take the power of the engine driven hydraulic pump drive shaft through a small hydraulic motor to rotate through reducer drive mixing drum rotates. During the transportation of concrete, the need to maintain the stirred tank 1-3 revolutions per minute at a low speed, in order to ensure homogeneous concrete, while preventing the concrete segregation, called agitation (stirring commonly known).

Truck loading function principle: when the concrete mixer in the mixing tank loading speed faster, speed of 6-10 rpm, concrete mixing tube through the charging system into the catheter from the tube, and in the helical blade guide, the flow of agitation in the lower part of the cylinder. Note: the direction of rotation during transport of the tank when the charging should be consistent, or in the concrete during transport will be discharged.

  Truck unloading function principle: when unloading truck engine will power through the PTO, hydraulic pumps, gear and other transmission to the mixing tank, drive tanks rotation speed of 3-14 rev / min; concrete blade By pushing the role of a spiral motion to move the cylinder port direction, after unloading bucket truck unloading. At this point the direction of rotation of the feed tank and in the opposite direction.

Mixer cleaning function principle: air reservoir tank to the braking system pressurized water through a pressurized mixing tank cleaning system, loading port, concrete mixer drum roller, unloading systems.

Feature stone cutting machine

Stone cutting machine, also known as stone by stone cutter machine is a group of stone transport units, multi-multi-level stone knife positioning guides and racks cutting machine

1. Cutter set in stone bench Department transported and placed on the rack, between the cutting knife set fixed positioning guide plate; cutter set by the motor, belts, knife shaft, cutting tool composed cutter knife fixed on the axle. This stone cutting machine for cutting stone separately at different depths can be less than 1m3 of stone less processed, turning waste into treasure, significant savings in stone resources, but also help protect the environment. Various types of stone can be mechanical cutting, high processing efficiency, coupled with the effective use of a small stone, so that production costs are lower.

2. In the machining process, sheet metal cutting methods are commonly used in hand-cut, semi-automatic cutting machine and CNC cutting machine. Hand-cut flexible and convenient, but poor quality hand-cut, size error, waste material large, subsequent processing workload, and poor working conditions, low productivity. Semi-automatic cutting machine in the profile cutting machine, better quality cutting of the workpiece, due to the use of cutting die, is not suitable for the single, small and large quantities of workpieces cut. Although other types of semi-automatic cutting machine reduces the labor intensity, but its function is simple, only for some of the more regularly shaped parts cutting. CNC cutting relatively manual and semi-automatic cutting mode, it can effectively improve the efficiency of sheet metal cutting, cutting quality, reduce the labor intensity of the operator. With the development of modern machinery industry, the requirements for sheet metal cutting efficiency and product quality also improved. Thus the market potential is still very large CNC cutting machine, the market outlook is more optimistic.

3. from a variety of CNC granite bridge saw the application point of view, the overall level of technical level, the overall performance of domestic production of CNC cutting machines have made ​​encouraging progress, and gradually catch up with the international advanced level, to meet the needs of users, further improve the market competitiveness. CNC plasma cutting some domestic product in many ways has formed its own unique characteristics, to achieve the "automation, versatility and reliability." In some respects, the technical performance of the product even more than foreign products. Improve productivity and cut quality CNC cutting machines, reduce production cost and improve the overall level of automation and system stability, improve the system functions become direction of technology development.
