A moving adjustment mechanism is fixedly installed between the two inclined guide blocks 4. The moving adjustment mechanism includes a first motor 5, an mounting plate 6 fixedly connected to one end of the discharge square cylinder 2, two mounting blocks 7 fixedly connected to the top end of the mounting plate 6, one end of the first motor 5 fixedly connected to one end of one of the mounting blocks 7, a bidirectional screw 8 fixedly connected to the output end of the first motor 5, and the other end of the bidirectional screw 8 rotatably connected to one end of the other mounting block 7. Two rotating screw sleeves 9 are screwed onto the outer wall. One end of each rotating screw sleeve 9 is fixedly connected to one end of each of the two inclined guide blocks 4. After connecting the connecting pipe 1 to the concrete discharge port, during the discharge process, the output end of the first motor 5 will drive the bidirectional screw 8 to rotate when the first motor 5 is powered on, and drive the rotating screw sleeve 9 to move through the thread. During the movement of the rotating screw sleeve 9, the distance between the two inclined guide blocks 4 is adjusted with the cooperation of the connecting blocks 10. Under the control of the two inclined guide blocks 4 in the discharge square cylinder 2, the size of the discharge port in the discharge square cylinder 2 is controlled, which further improves the effect of convenient adjustment of the discharge port diameter during concrete mixing and discharge.

[0015] It should also be noted that buffer grooves are provided at the top of both extended channels, and movable sliders 11 are slidably connected to both ends of the two buffer grooves.

Buffer springs 14 are fixedly installed between the top of the two movable blocks 12 and the top of the two buffer grooves, respectively. When the tilting guide block 4 moves, and through the contact between the tilting guide block 4 and the movable tilting block 13, the sealing effect of the extended channels is further enhanced when the tilting guide block 4 moves further. Sealing strips are fixedly installed at both ends of 4 and at both ends of the two movable tilting blocks 13 to improve the sealing effect of the tilting guide block 4 and the movable tilting block 13. A control valve 15 is fixedly installed on the outer wall of the connecting pipe 1. A discharge funnel is fixedly installed at the bottom end of the discharge square cylinder 2 to further expand the discharge effect and range of the discharge square cylinder 2. Sliding blocks 16 are fixedly connected to the bottom ends of the two rotating screw sleeves 9.

[0016] The first motor 5 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements, and we will not go into detail about it here.

[0017] In summary, when using this auxiliary discharge device for concrete mixing, firstly, the connecting pipe 1 is connected to the concrete discharge port. During the discharge process, the output end of the first motor 5, powered on, drives the bidirectional screw 8 to rotate, and through the thread, drives the rotating sleeve 9 to move.
