The concrete is introduced into the interior of the pipe 1, the concrete moves in the interior of the pipe 1, the motor 51 is turned on, the motor 51 drives the rotating shaft 52 to rotate inside the fixed disk 22, the piston 61 and the pipeline 1, the rotating shaft 52 drives the connecting mechanism 8 and the fixed shaft 43 to rotate, the fixed shaft 43 drives the stirring plate 41 with the arc-shaped side wall to rotate at the turning position of the pipeline 1, the stirring plate 41 pushes the concrete at the turning part of the pipeline 1 to move, so as to avoid the concrete from blocking the bending part of the pipeline 1, and the stirring plate 41 pushes the concrete to move rapidly inside the pipeline 1, and the lugs 42 are installed on the side wall of the stirring plate 41 at equal intervals, the lug 42 is in contact with the concrete, so that the friction force between the stirring plate 41 and the concrete is increased, and the stirring plate 41 is convenient to push the concrete; the concrete motion is beaten and is in the lateral wall of stirring board 41 makes stirring board 41 is in rubber sleeve 45 with the inside of fixed axle 43 is rocked, makes stirring board 41 slightly rocks, avoids stirring board 41 damages, just stirring board 41 with be located inside fixed axle 43 install between the baffle 44 spring 46, the concrete extrusion stirring board 41, the extrusion of stirring board 41 spring 46 with rubber sleeve 45, spring 46 with rubber sleeve 45 does the shock attenuation of stirring board 41 reduces the motion range of stirring board 41. In the using process, some concrete falls into the inside of the fixing ring 62, the cross section area of the fixing ring 62 is trapezoidal, the inclined direction of the fixing ring 62 inclines towards the center of the fixing ring 62 along the edge of the fixing ring 62, and the concrete in the fixing ring 62 conveniently slides out from the inside of the fixing ring 62. The cylinder 21 is rotated downwards to take out the conveying mechanism 4, the screw 84 is removed, the fixing sleeve 82 is slid upwards, the mounting rod 72 is taken out from the inside of the fixing shaft 43, the fixing shaft 43 is separated from the rotating shaft 52, and people can clean the conveying mechanism 4 conveniently.

Compared with the related art, the concrete conveying device provided by the invention has the following beneficial effects:

the invention provides a concrete conveying device, when concrete slides in the pipeline 1, the driving mechanism 5 drives the connecting mechanism 8 and the fixed shaft 43 to rotate in the pipeline 1, the fixed shaft 43 drives the stirring plate 41 with the arc-shaped side wall to rotate at the turning part of the pipeline 1, the stirring plate 41 pushes the concrete at the turning part of the pipeline 1 to move, the concrete is prevented from blocking the bending part of the pipeline 1, the stirring plate 41 pushes the concrete to rapidly move in the pipeline 1, the lugs 42 are arranged on the side wall of the stirring plate 41 at equal intervals, the lugs 42 are contacted with the concrete, the friction force between the stirring plate 41 and the concrete is increased, and the stirring plate 41 is convenient to push the concrete; the concrete motion is beaten and is in the lateral wall of stirring board 41 makes stirring board 41 is in rubber sleeve 45 with the inside of fixed axle 43 is rocked, makes stirring board 41 slightly rocks, avoids stirring board 41 damages, just stirring board 41 with be located inside fixed axle 43 install between the baffle 44 spring 46, the concrete extrusion stirring board 41, the extrusion of stirring board 41 spring 46 with rubber sleeve 45, spring 46 with rubber sleeve 45 does the shock attenuation of stirring board 41 reduces the motion range of stirring board 41.

The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
