The invention has the outstanding advantages that:

1. this kind of controllable adjustable silo down of bituminous paving cares car is through the flexible length adjustment of silo under first silo, the every single move angular adjustment of silo under the second and the relative first silo of silo under the second, realizes the automatic adjustment of bituminous mixture blanking position and blanking height, has avoided relying on the manual work to utilize small handcart or other instruments, transports the bituminous mixture of regeneration the road surface and treats the maintenance district and carry out the process that the disease filled the operation, has reduced workman's intensity of labour and construction cost.

2. This kind of controllable adjustable unloading groove of bituminous paving cares car realizes bituminous mixture unloading position and height's adjustment through a revolute pair and two linear actuator, and not only simple structure, first linear actuator, second linear actuator are the electricity liquid push rod moreover, compare the pneumatic cylinder drive and need not establish independent hydraulic pump and return circuit, and is with low costs, the good reliability.
