[0029] When this embodiment is in use, the concrete inside the weighing box 3 is weighed by the weighing platform 5. After the weighing is completed, the stepping motor 12 is started to drive the reciprocating screw 15 to rotate. At the same time, the pushing plate 11 moves along the surface of the reciprocating screw 15 and abuts against one side of the weighing box 3, so that the weighing box 3 can slide down from the surface of the lowered unloading plate 2 for unloading, thereby improving the convenience of unloading and saving human resources.

[0030] When the pushing plate 11 starts to move, the staff can move the scraper 137 upward to compress the abutting spring 136.
