[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0028] Example 1:

[0029] See Figure 3 、 4 A discharge pipe unit 40 includes a plurality of butt-jointed connecting pipes 42, a collecting hopper 41, an elbow 43, and a hose 44. The collecting hopper 41 is mounted on the upper end of the uppermost connecting pipe 42, the elbow 43 is mounted on the lower end of the lowermost connecting pipe 42, and the hose 44 is butted against the elbow 43. At least one of the connecting pipes 42 is provided with a bend 421. The bend 421 and the elbow 43 at the lower end of the lowermost connecting pipe 42 increase the resistance to concrete falling and slow its falling speed, thereby preventing concrete segregation caused by free fall within the longitudinal connecting pipe 42.

[0030] In this embodiment, see Figure 4 The bent portion 421 is formed by welding one or two displacement joints. Of course, in addition to the above structure, the bent portion 421 can also be formed by welding two or four 90° elbows.

[0031] Furthermore, in order to facilitate the connection between the upper and lower connecting pipes 42, the upper and lower connecting pipes 42 are butted together by flanges, that is, the ends of adjacent connecting pipes 42 are welded to the flanges, and the adjacent flanges are connected by bolts.

[0032] See also Figure 3 The collecting hopper 41 is funnel-shaped, and a flange is also welded to the lower end of the collecting hopper 41. The collecting hopper 41 is also connected to the upper end of the connecting pipe 42 by bolts through the flange.

[0033] Furthermore, in order to facilitate the swing angle of the hose 44 during operation, the elbow 43 adopts a 90° return elbow. Wherein, the 90° return elbow is a prior art and can be purchased on the market.

[0034] The hose 44 is sleeved on the lower end of the elbow 43 and can be fixed by tying with wire.

[0035] Example 2:

[0036] See also Figure 1-6 A concrete discharging system for a wellhead mixing station includes a mixer 10, a chute 20, and a discharging pipe unit 40. The mixer 10 is elevated above the ground, and the chute 20 is tilted. The mixer 10 has a discharging port 11 located at the upper end of the chute 20, and the lower end of the chute 20 is located above a collecting hopper 41. Multiple connecting pipes 42 are longitudinally mounted on the inner wall of a vertical shaft 100 via connecting bases 50. The mixer 10 is used to mix concrete. The mixed concrete passes through the chute 20 and enters the collecting hopper 41 of the discharging pipe unit 40. After passing through the connecting pipe 42 and the elbow 43, it is discharged from the hose 44, thereby pouring concrete onto the pouring bin surface 101.

[0037] For details, see Figure 1 、 2 The mixer 10 is mounted on a bracket 12, and the chute 20 is mounted on a bent frame 30. The bracket 12 supports the mixer 10 and provides a high mounting height for the mixer 10. The bracket 12 can be fabricated as a metal frame as needed. The bent frame 30 can be a welded metal frame or, to reduce costs, can be constructed from scaffolding steel pipes. The chute 20 is mounted on top of the bent frame 30.

[0038] See also Figure 6 The connecting seat 50 includes an anchor rod 51 and a half ring 52. The two ends of the two half rings 52 are connected by bolts. A nut sleeve 53 is provided on the outer wall of one of the half rings 52. The anchor rod 51 is screwed with the nut sleeve 53. A positioning nut 54 is also screwed on the anchor rod 51. When in use, refer to Figure 4 One end of the anchor rod 51 is used to be installed in the rock formation, and the other end is provided with an external thread to be screwed with the nut sleeve 53. The two half rings 52 are connected by bolts at both ends to hold the connecting pipe 42. The positioning nut 54 is used to fix the nut sleeve 53 to prevent the nut sleeve 53 from shaking.

[0039] The working principle or action process of the utility model is as follows:

[0040] See also Figure 1 、 5The concrete mixed by the mixer 10 is discharged from the mixer's discharge port 11 into the upper end of the chute 20. The lower end of the chute 20 is located above the collecting hopper 41. Multiple connecting pipes 42 are longitudinally mounted on the inner wall of the shaft 100 via connectors 50. The mixed concrete passes through the chute 20 and enters the collecting hopper 41 of the discharge pipe unit 40. After passing through the connecting pipes 42 and elbows 43, it is discharged from the hose 44, thereby pouring concrete onto the casting silo 101. The bends 421 provided on the connecting pipes 42 and the elbow 43 installed at the lower end of the lowest connecting pipe 42 increase the resistance to the concrete's fall and slow its speed, thereby preventing concrete segregation caused by free fall within the longitudinal connecting pipes 42.
