Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Example (b): a double-layer protection type concrete discharging device is shown in figure 1 and comprises a hopper 1 with a plurality of discharging pipes 11 arranged at the bottom, wherein electromagnetic control valves 2 are respectively arranged in the middles of the discharging pipes 11.

As shown in fig. 1 and 2, the bottom surfaces of the discharge pipes 11 are arc surfaces, the discharge pipes 11 are rotatably connected with end caps 3 having arc plates 31 capable of completely closing the bottom surfaces of the discharge pipes 11 during rotation, and a manual adjustment mechanism for simultaneously driving the end caps 3 to rotate is arranged between the end caps 3 and the hopper 1.

As shown in fig. 1 and 2, the manual adjusting mechanism includes a plurality of adjusting gears 41 fixedly disposed at the rotating positions of the end caps 3, respectively, adjusting racks 42 slidably coupled to the hopper 1 along the horizontal direction and respectively engaged with the plurality of adjusting gears 41, and a manual adjusting assembly 43 disposed between the adjusting racks 42 and the hopper 1 and driving the adjusting racks 42 to move, wherein the center line of the adjusting gears 41 coincides with the rotating axis of the end caps 3.

As shown in fig. 1, a plurality of support rods 12 extending in the vertical direction and distributed in a horizontal direction are welded to the hopper 1, and a stop collar 13 for passing an adjusting rack 42 is fixedly arranged below the support rods 12.
