[0025] After the concrete processing in the mixing station is completed, it can be put into the lower hopper 1 for pre-storage. It should be noted that the storage time of the concrete in the lower hopper 1 cannot exceed 30 minutes to avoid solidification. If concrete is put into the mixer truck, first open the two first electric telescopic rods 5 at the same time, the telescopic ends of the two first electric telescopic rods 5 shrink and drive the "U"-shaped mounting seat 61 to move, so that the "U"-shaped mounting seat 61 pulls the arc door 3 through the second rotating shaft 62, so that the arc door 3 can rotate and open the discharge port of the lower hopper 1, so that the concrete in the lower hopper 1 can be discharged from the discharge port and enter the mixer truck, thereby completing the work of adding concrete to the mixer truck.
