TECHNICAL FIELD

[0001] The utility model relates to mixing machine technical field, concretely relates to a discharge structure of mixing machine. BACKGROUND

[0002] After the material is mixed uniformly by the mixing machine, the material needs to be guided out through the discharge structure. For example, the Chinese utility model patent with the application number CN202322482024.2 applied by the applicant on September 13, 2023 discloses a discharge device of a mixing machine, which comprises a discharge port. The discharge port is arranged on the center of one end of a drum cylinder. The cylinder rotates along the central axis, so that the position of the discharge port does not change during the rotation of the cylinder. The cylinder comprises a cover body. The shape of the cover body is hollow conical. One end of the cover body is provided with the discharge port, and the other end is connected with a cylindrical barrel. The discharge device further comprises a conveying assembly. One end of the conveying assembly extends to the discharge port. The other end of the conveying assembly is arranged at one end of the cover body away from the discharge port. The rotation of the cylinder enables the conveying assembly to convey the material in the inner cavity of the mixing machine to the discharge port. However, in actual use, the straight strip type guide belt has a small amount of material to be conveyed, and the material is prone to backflow, which slows down the discharging speed. SUMMARY

[0003] In view of the deficiencies in the background art, the technical problem to be solved by the utility model is to provide a discharge structure of a mixing machine with a faster discharging speed.

[0004] To this end, the utility model is implemented by adopting the following technical solutions:

[0005] A discharge structure of a mixing machine, comprising a discharge inclined cone connected with a drum of the mixing machine, the discharge inclined cone having a discharge port, characterized in that: a discharge flange is movably connected to the discharge port, and the other end of the discharge flange is provided with a discharge hopper with the outlet facing downward; a plurality of guide fins are arranged on the inner wall of the discharge inclined cone, the guide fins extend from the right end of the discharge inclined cone to the position of the discharge port, the guide fins are arc-shaped as a whole, and the included angle between the guide fins and the inner wall of the discharge inclined cone is an acute angle; and the guide fins and the discharge inclined cone form a feeding groove.

[0006] Further, a transition ring is arranged on the inner wall of the discharge flange. The transition ring is raised in the middle to form an angle, and one side of the transition ring is smoothly connected with the inner wall of the discharge inclined cone, and the other side is smoothly connected with the inner wall of the discharge hopper.

[0007] Further, a cylinder is arranged on the discharge hopper. The driving rod of the cylinder is inserted into the discharge hopper. The driving rod is provided with a discharge tongue which can abut against the transition ring.

[0008] Further, a plurality of sleeves are arranged on the discharge hopper. A guide rod is movably arranged in the sleeves. The inner end of the guide rod is connected with the discharge tongue.

[0009] Further, the outer circle of the discharge tongue is provided with an annular groove, and a sealing ring is arranged in the annular groove and can abut on the transition ring.

[0010] Further, the discharge flange is fixed on the support through a plurality of bolts.

[0011] Further, the thin-wall bearing, the graphite packing sealing assembly and the plurality of O-shaped sealing rings are arranged between the discharge inclined cone and the discharge flange.

[0012] After the above technical scheme is adopted, the material is not discharged when the discharge inclined cone is positively rotated, and the material can enter the feeding groove and move to the discharge port for discharging when the discharge inclined cone is reversely rotated. Since the guide piece is in an arc shape, more material can be loaded in the feeding groove, and the discharging speed is increased. Moreover, the material can slide to the bottom of the feeding groove (arc shape) due to gravity, and the bottom of the feeding groove (arc shape) is continuously changed with the continuous reverse rotation of the discharge inclined cone, so that the material always has a tendency to slide to the discharge port, and the discharging speed is further increased.

DETAILED DESCRIPTION

[0019] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific implementation, structure, features and effects according to the utility model are described in detail as follows by combining with the drawings and preferred embodiments.

[0020] The utility model provides a kind of discharging structure of mixing machine, which comprises a discharging inclined cone 2 connected with a mixing machine roller 1, the discharging inclined cone 2 has a discharge port 3, characterized in that: the discharge port 3 is movably connected with a discharging flange 4, the other end of the discharging flange 4 is provided with a discharging hopper 5 with its outlet downward, the inner wall of the discharging inclined cone 2 is provided with a plurality of guide vanes 6, the guide vanes 6 extend from the right end of the discharging inclined cone 2 to the position of the discharge port 3, the guide vanes 6 are arc-shaped as a whole, and the included angle between the guide vanes 6 and the inner wall of the discharging inclined cone 2 is an acute angle, the guide vanes 6 and the discharging inclined cone 2 form a feeding groove 7, the inner wall of the discharging flange 4 is provided with a transition ring 8, the transition ring 8 is raised inward in the middle to form an angle, one side of the transition ring 8 smoothly transitions with the inner wall of the discharging inclined cone 2, and the other side smoothly transitions with the inner wall of the discharging hopper 5, the discharging hopper 5 is provided with a cylinder 9, the driving rod 10 of the cylinder 9 is inserted into the discharging hopper 5, the driving rod 10 is provided with a discharging tongue 11 that can abut on the transition ring 8, a plurality of sleeves 12 are provided on the discharging hopper 5, the sleeves 12 are movably provided with guide rods 13, the inner ends of the guide rods 13 are connected with the discharging tongue 11, the outer ring of the discharging tongue 11 is provided with an annular groove 14, the annular groove 14 is provided with a sealing ring 15 that can abut on the transition ring 8, the discharging flange 4 is fixed on a support 20 by a plurality of bolts 16, the discharging inclined cone 2 and the discharging flange 4 are provided with a thin-wall bearing 17, a graphite packing seal assembly 18 and a plurality of O-shaped sealing rings 19.

[0021] In the embodiment, the discharge bevel 2 is not rotated when the discharge operation is not performed, and the material will enter the feeding groove 7 and move to the discharge port 3 position to perform the discharge operation when the discharge bevel 2 is reversed.
