Background
The remixer is a hot in-place recycling host machine, and is generally arranged after 2-3 asphalt pavement heating machines and heating milling machines (the heating machines complete asphalt pavement heating and softening, and the heating milling machines complete pavement milling and forming recycled material piles), and is used for completing operations such as new asphalt mixture adding, material lifting, mixing and the like, and the remixer in the current market has the following defects:
(1) the working condition adaptability of the receiving device is poor. The concrete points are as follows: firstly, after the receiving device is filled with asphalt materials, the weight is more than 10 tons, and the load of a machine bridge is large, so that the machine is trapped by wheels and rolls the original pavement to cause grading damage; secondly, the simple supporting wheels are adopted by the material receiving devices of the remixers in the market to relieve the pavement rolling grading damage, so that the problem that the pavement grading damage is caused by the rubbing of the simple supporting wheels caused by the rotation guidance of the front wheels of the remixers cannot be solved; the material receiving device of the remixer in the market cannot timely adjust the posture according to the uphill and downhill road surfaces, the left and right road surfaces unevenness and the like, and the operation adaptability is poor;
(2) good reclaimed material temperature and pavement thermal connection temperature cannot be achieved. The concrete points are as follows: firstly, remixers in the market do not have special secondary temperature raising devices, and the problem of poor regeneration quality caused by low spreading temperature of reclaimed materials due to low temperature of a new asphalt mixture cannot be solved; secondly, a part of remixers are provided with simple secondary temperature raising devices, the material pile is directly heated by adopting an infrared device or a hot air heating device, the heating is only the surface layer of the asphalt mixture, sufficient time is needed for downward heat transfer, and the comprehensive temperature of the asphalt mixture still does not reach the standard; and the secondary temperature raising device in the market cannot simultaneously give consideration to both the secondary temperature raising of the asphalt mixture and the pavement thermal connection to achieve a good construction effect.

A large amount of water vapor and smoke dust are generated in the heating, material extracting and stirring links of the asphalt mixture, the water vapor and the smoke dust are all discharged in an unorganized mode, environmental pollution exists, heat leakage smoke is burnt, green belt vegetation is fumigated, and environmental damage is caused.
(4) The driver has bad operating environment, great body injury and no safety guarantee. The in-situ heat regeneration construction operation is very severe, the temperature of the operation environment is usually more than 40 ℃, toxic asphalt smoke or smoke dust emission is in different degrees, most of operation platforms of the existing in-situ heat regeneration equipment are simple driving sheds or sunshade sheds, drivers are completely exposed in the environment of open sun exposure and high-temperature toxic smoke, the harm to the bodies of the drivers is great, and fatigue operation causes driving safety; in-situ hot recycling construction, in order to clearly see information communication between road markings and vehicle groups, a driver usually rotates a seat to roll out or slides the seat to slide out of a vehicle body by more than 0.5 m, people and the seat are completely suspended on a high-temperature asphalt pavement, and serious driving safety risk exists;
(5) overcrowding, overweight, overrun. In the market, remixers all adopt a single heating wall, the size is large, the diameter, the length and the like of a hearth of a hot blast stove are also large, so that the overall size is large, the weight exceeds the standard, and climbing and transition are difficult.
The defects cause that the remixer on the market cannot meet the requirements of safe maintenance and high-standard and high-quality maintenance of modern asphalt pavements (particularly expressways and municipal roads).
