Substance vehicle of pyrolysis reactor

A substance vehicle of pyrolysis reactor, applicable to load and transport a pyrolysis substance, comprising:

• a vehicle body, having at least two volume spaces separated by a separator, the at least two volume spaces being not communicating, and a top of the at least two volume spaces being fully opened for allowing the pyrolysis substances to be placed into the at least two volume spaces;
• at least two movable doors, movably disposed at a bottom of the at least two volume spaces, wherein the at least two movable doors are operated independently;
• and
• at least two fixed units, being in L-shaped and comprised of a long strut and a short strut, the long strut corresponding to the at least two volume spaces disposed on a side edge of the vehicle body, and an end of the long strut adjacent to the bottom of the at least two volume spaces connected with the short strut, wherein each of the at least two fixed units controls an operation of one of the at least two movable doors respectively;
• wherein the short strut is reciprocally rotatable between a first position and a second position around an axis along an axial direction of the vehicle body, the short strut is located below the at least two movable doors to prevent opening the at least two movable doors in the first position, and the short strut is in the second position while disengaging from the bottom of the at least two movable doors, such that the at least two movable doors are opened by gravity.
