AI Technical Summary
When concrete is discharged, due to the fixed structure of the discharge port, the discharge port is prone to influx, accumulation and blockage when the discharge is too fast, affecting the smooth discharge of concrete.
A rotary concrete discharge port is designed. By setting a rotating cylinder on the lower side of the main body of the discharge port, the drive motor, driving wheel and driven ring are used to drive the rotating cylinder to rotate, driving the connecting frame and mixing blade to rotate, so that the discharge port is realized. Continuous stirring at the material opening prevents clogging.
Through continuous mixing, the discharge port is effectively prevented from clogging, ensuring smooth discharge of concrete, and components can be quickly separated and cleaned after use.

Technical Field
[0001] The utility model relates to the technical field of concrete, in particular to a rotary concrete discharge port. Background Art
[0002] Concrete is a general term for engineering composite materials that are made of cementitious materials that bind aggregates into a whole.

DETAILED DESCRIPTION
[0019] Based on the embodiments of the present utility model, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present utility model.
[0020] like Figure 1-5 As shown, a rotary concrete discharge port comprises a discharge port body 1 , a rotating cylinder 2 is sleeved on the bottom of the discharge port body 1 , and an assembly frame 3 is arranged on the lower side of the rotating cylinder 2 .
[0021] An opening is provided at the front end of the assembly frame 3, and a connecting frame 4 is inserted at the opening. The two sides of the connecting frame 4 are connected to the two sides of the assembly frame 3 by bolts and nuts. Stirring blades 5 are vertically distributed on both sides of the connecting frame 4. A through groove 6 is provided on the upper side of the discharge port body 1, and a slide groove 7 is provided at the bottom of the through groove 6. A circle of sliding components is provided on the upper side of the rotating cylinder 2, and the upper side of the sliding component is slidably connected with the slide groove 7. A fixed frame 8 is provided on the upper side of the discharge port body 1, and a driving motor 9 is installed on the lower side of the fixed frame 8. The driving end of the driving motor 9 is connected to a driving wheel 10, and a driven circle 11 is provided on the outer side of the rotating cylinder 2, and the driven circle 11 is meshed with the driving wheel 10.
[0022] The sliding assembly is mainly composed of a connecting seat 12 , a vertical rod 13 , a connecting block 14 and a sliding block 15 .
[0023] The connecting seat 12 is connected to the upper outer wall of the rotating cylinder 2 by screws, the bottom of the vertical rod 13 is welded to the top of the connecting seat 12, the rear side of the connecting block 14 is welded to the upper side of the vertical rod 13, and the sliding block 15 is arranged at the bottom of the connecting block 14.
[0024] In the present technical scheme, before discharging the concrete inside the silo, the operator first needs to plug the connecting frame 4 into the front end opening of the assembly frame 3, and use bolts and nuts to connect the connecting frame 4 to the assembly frame 3, and then plug the top of the rotating cylinder 2 into the bottom of the discharge port body 1, and then use screws to connect the connecting seat 12, the vertical rod 13 and the connecting block 14 to the rotating cylinder 2. At this time, the connecting block 14 will be inserted into the through groove 6, and then under the influence of gravity, the slider 15 located at the bottom of the connecting block 14 will be plugged into the slide groove 7, and at the same time, the stirring blades 5 vertically arranged on the upper side of the connecting frame 4 will extend into the discharge port body 1.
[0025] After the rotating drum 2 is assembled, the driving wheel 10 at the driving end of the driving motor 9 is meshed with the driven ring 11. The outer surfaces of the driving wheel 10 and the driven ring 11 are made of rough rubber material, and there is enough friction between the two. Then the driving motor 9 is controlled to run, and the driving wheel 10 and the driven ring 11 can cooperate to drive the rotating drum 2 and the stirring blades 5 inside the rotating drum 2 to rotate along the slide groove 7, so as to continuously stir the inside of the discharge port body 1 during the discharging process, thereby preventing the discharge port body 1 from being blocked. In addition, since the concrete will generate a vertical downward force on the rotating drum 2 as a whole during the discharging process, the connecting block 14 and the slider 15 will be firmly buckled in the through groove 6 and the slide groove 7, so that the connecting block 14 and the slider 15 will not fall off.
[0026] The fixing frame 8 is designed to be L-shaped as a whole. Since the lower side of the fixing frame 8 is suspended in the air, a first reinforcing rib 16 is provided at the L-shaped bending portion of the fixing frame 8. At the same time, a circle of second reinforcing ribs 17 is provided at the connection between the fixing frame 8 and the discharge port body 1 to increase the overall stability of the fixing frame 8 and prevent the fixing frame 8 from shaking.
[0027] The connecting block 14 and the sliding block 15 are both designed to be arc-shaped, so as to increase the fit between the two and the through groove 6 and the slideway, and further increase the stability of the rotating drum 2 during rotation.
[0028] Furthermore, the outer diameter of the discharge port body 1 is smaller than the inner diameter of the rotating cylinder 2 , and the upper side of the connecting frame 4 extends into the interior of the discharge port body 1 .
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
