Remixer

Remixer - is, in fact, the car "Repaver", equipped with additional dosing and mixing units. Warmed up the old asphalt loosen knives, and then screw valve and located behind the blade is fed into the mixing unit equipped with two shafts. Fresh mix from the hopper conveyor enters the dosing unit, which sends it to the mixer, where the old and the new masses are mixed. The resulting mixture is fed to the working bodies that distribute it, and bury the old , while high-quality pre-compaction.

The final mixture is compacted by rollers as in the method of "repave" and using the method of "remix".

Cars with equipment for digging wells. For repair and maintenance of city streets, driveways and roads it is usually necessary to dig a hole under the fence posts, road signs and planting of greenery. For this purpose, using special drilling and crane machines.

By construction, the Boers are divided on the screw and vane with a conical working surface. I screw augers transporting surface is formed by rotating a line perpendicular to the axis of the drill, and moving along a helix of constant pitch. Paddle the Boers have a conical surface with its center of rotation

on the axis of the drill. Screw augers are useful when the ratio of depth to diameter drill holes larger than 1. Screw augers may be one, two and trehzahodnymi.

Attached drilling and crane machines BM-202 BM-302 is mounted on the the GAZ-66-02 and consists of a base frame, a working body, supporting gidrodonkratov, hydraulic drive and control systems. The working body, in turn, consists of a rotator, rod, pipe support, crane devices and fencing. Mounted on the shank of the drill rod. The working body is rotated in the longitudinal plane with the cylinder. When operating the drill hydraulic jacks unload the rear axle.

Upgraded versions of drilling and crane machines BM-202 BM-302 - Machine MB-202A and MB-302A - the execution of some of the different structural units and mechanisms: the transfer case clutch brake clutch mechanism is used, the rod with the ball head set seal rubber ring, improved design of the jack, increased tank capacity, improved control panel and feeder drilling tools.

Energy balance remonterov spend on formulas similar to the case of calculating machines for the destruction of asphalt pavement. In determining the cost of power to drive the auger is used the results of experimental studies that feed auger to 10-12 mm per revolution is required to attach to the body of the working force (15-20) 103 N. In the case of rotation of the drill with the angular velocity of 15.7 rad / s capacity is lost by an average of 25-30 kW.



We recommend to look

  • The drive compressor
    The drive is made ​​from the compressor PTO engine GAZ-53A through the gearbox, driveline and transmission belt. On the gear drive compressors mounted gear pump NSh-10E, which serves the work of hydraulic machines. In the working position hopper hydraulic cylinder rises thermos, allowing automatic translation of the bucket truck-mounted on the rear bodywork and manual vibratory rollers of the transport to working position. Bucket-truck [...]
  • Machine DE-5A
    Machine DE-5A is intended for maintenance of city streets and highways with asphalt. Special equipment vehicles placed on the chassis of GAZ-53A and consists of a hopper-the thermostat for the transportation and storage of hot asphalt mix, with pneumatic compressor, gas equipment - block infrared burners, tanks, hoses, hand tools for painting and road conditions [. ..]
  • Bunker thermos
    Hopper provides storage thermos of hot asphalt mix. The mixture is fed into the truck through the open (with cylinder) hopper bin, after which the mixture is transported to the site of work. The torque from the surface of the power takeoff shaft, flanged to the gearbox base unit is transmitted to the input shaft of the hydraulic pump, and from the bottom of the shaft - the input shaft of the generator [...]
  • Asfaltorazogrevatel DOE-2
    Asfaltorazogrevatel DOE-2 on the chassis of the vehicle UAZ-451DM consists of a creeper with arms control, body, LPG ​​installations, communication, power burners with infrared gas burners such as TIG-1, the lifting mechanism block burners, hydraulic and electrical equipment. In order to improve the quality of work, reducing the time of heating and gas flow rate on asfaltorazogrevatelyah establish a system of automatic regulation (SAR) of the process of heating surface. [...]
  • Warming unit coating after cleaning the burners
    Repairable coating after it is clean and warm up the block layout of burners: the whole area - the repair of small cards, and on the perimeter of the marked path - in the repair of large maps. After the backwash rakes heated asphalt concrete pavement to a depth of 3-4 cm and supplements in the recommended location of the new material from the hopper, a thermos is a new material is mixed with hot [...]
