5. The lightweight concrete panel processing apparatus as set forth in claim 4, further comprising a strickle mechanism including a scraper provided on the long bar for strickleing off the top of the mold filled with concrete.

6. The lightweight concrete panel processing apparatus as claimed in claim 1, further comprising a cleaning mechanism, said cleaning mechanism being mounted on said carriage, said cleaning mechanism comprising a plurality of fan blades rotatably mounted on said carriage, said drive assembly being drivingly connected to said fan blades and adapted to drive said fan blades to rotate about their central axis.

7. The lightweight concrete panel processing apparatus as set forth in claim 1, further comprising a vibration means, said vibration means comprising a plurality of elastic hammering members uniformly disposed on a side wall of the sliding frame adjacent to the mold, and an arc-shaped projection disposed on an outer side wall of the mold and engaged with the elastic hammering members.

8. The lightweight concrete panel processing apparatus as set forth in claim 7, wherein said elastic hammering assembly comprises an elastic rod having one end connected to the carriage, and a ball-shaped hammer connected to the other end of the elastic rod, the ball-shaped hammer being in pressing contact with the arc-shaped projection so that the elastic rod is compressed, and the elastic rod is restored to push the ball-shaped hammer to hit the mold when the ball-shaped hammer is separated from the arc-shaped projection.

9. The lightweight concrete panel processing apparatus as claimed in claim 1, wherein said rotating tank wall comprises a straight cylinder section rotatably connected to the tank bottom, and a conical cylinder section fixedly connected to the top of the straight cylinder section, said agitating blade is connected to the inner side wall of the straight cylinder section, and the diameter of the conical cylinder section decreases from bottom to top.

10. A method of working lightweight concrete panels, using the working apparatus as claimed in any one of claims 1 to 9, comprising the steps of:

feeding, namely feeding materials into a stirring and feeding mechanism through a feeding hole, and rotating a tank wall to drive a stirring blade to rotate so as to stir concrete;

stopping feeding, wherein the elastic support assembly is shortened due to the increased pressure along with the increase of the amount of the concrete filled in the mould, the height of the mould is continuously reduced, when the mould is filled with the concrete, the limiting handle is separated from the stop lever, the return spring pushes the baffle to return, and the baffle blocks the discharge hole again;
