DETAILED DESCRIPTION
[0017] like Figures 1 to 4 As shown, a cement grouting machine of the present invention comprises a fixed frame 1, and a diversion grouting device 2 for dispersing the flow of concrete is connected to the upper part of the fixed frame 1. A mold clamping device 3 for fixing the mold is slidably connected to the upper part of the fixed frame 1, and the diversion grouting device 2 comprises: a motor 22, a first belt reel 25, a second belt reel 26, a diversion port 21, a rotating shaft 28, a connecting plate 27, a rotating disk 24, a fixed plate 29 and a diversion plate 23. The fixed plate 29 is fixedly connected to the upper part of the fixed frame 1, and one end of the diversion port 21 passes through the fixed plate 29, and the lower end of the diversion port 21 is conical, which is convenient for concrete to flow in.
[0018] One end of the motor 22 is fixedly connected to the fixed plate 29, and the output shaft of the motor 22 passes through the fixed plate 29 and is fixedly connected to the first belt reel 25, so that the motor 22 drives the first belt reel 25 to rotate. The second belt reel 26 is hollow inside, and the second belt reel 26 is rotatably and sealedly connected to the lower end of the diversion port 21, so that concrete will not flow out when the second belt reel 26 rotates. A belt 16 is connected between the first belt reel 25 and the second belt reel 26, and the first belt reel 25 drives the second belt reel 26 to rotate. There are multiple connecting plates 27, and one end of multiple connecting plates 27 is fixedly connected to the inner side of the second belt reel 26. The rotation of the connecting plates 27 can prevent the concrete from gathering. The other ends of the multiple connecting plates 27 are connected to the rotating shaft 28, and the second belt reel 26 drives the connecting plates 27 and the rotating shaft 28 to rotate. The upper end of the rotating shaft 28 is fixedly connected to the rotating disk 24, and the rotating shaft 28 drives the rotating disk 24 to rotate. The diverter plates 23 are arranged in multiple pieces obliquely on the outside of the rotating disk 24 to divert the concrete. The upper end of the fixed frame 1 is connected to the first electric cylinder 4, and the output shaft of the first electric cylinder 4 is connected to the traction belt 5, and the first electric cylinder 4 pulls the traction belt 5. One end of the traction belt 5 passes through the side of the fixed frame 1 and is fixedly connected to the side of the mold clamping device 3, and the traction belt 5 pulls the mold clamping device 3 to move.
[0019] The working principle of the above scheme is as follows: concrete is poured into the diversion port 21, and the motor 22 is started to drive the first belt reel 25 to rotate. The first belt reel 25 rotates the second belt reel 26 through the belt 16, and the second belt reel 26 drives the connecting plate 27 and the rotating shaft 28 to rotate. The rotating shaft 28 drives the rotating disk 24 and the diversion plate 23 to rotate to break up and divert the concrete. At this time, the concrete passes through the second belt reel 26 and the connecting plate 27 to break up the concrete again, and the concrete falls into the clamping device 3. When the clamping device 3 needs to move on the fixed frame 1 to adjust the orientation, the first electric cylinder 4 is used to drive the clamping device 3 to slide on the fixed frame 1.
[0020] The beneficial effects of the above scheme are as follows: after the concrete and other materials are put into the diversion port 21 through the diversion grouting device 2, the concrete will not be concentrated into the clamping device 3, thereby generating a large amount of air and causing bubbles to be generated inside the concrete; the concrete is divided into multiple streams and flows into the clamping device 3 through the diversion plate 23, thereby reducing the air brought up by the concrete when it descends; the connecting plate 27 prevents the concrete from gathering together when passing through the second belt disk 26; the clamping device 3 is pulled to move by the first electric cylinder 4, so that multiple clamping devices 3 can slide on the fixed frame 1 to adjust the orientation.
[0021] In one embodiment of the present invention, Figures 1 to 6 As shown, there are multiple mold clamping devices 3 and the multiple mold clamping devices 3 are connected by a traction belt 5, and there are also multiple diversion grouting devices 2 corresponding to the mold clamping devices 3.

The other end of the traction belt 5 passes through the fixing frame 1 and is connected to a winding drum 6 , which is fixedly connected to the side of the fixing frame 1 . The winding drum 6 can pull the second outer protective shell 32 to move, so that the first outer protective shell 31 is separated from the second outer protective shell 32 .
[0022] The first mold 35 is slidably connected to the lower end of the first outer protective shell 31, and the second mold 37 is slidably connected to the lower end of the second outer protective shell 32. The telescopic rod 39 has multiple roots connected to the inner side of the first outer protective shell 31 and the second outer protective shell 32, so that they can move horizontally left and right. The spring 38 has multiple roots located at one end of the telescopic rod 39 to achieve the effect of rebound and reset. The two protrusions 312 are respectively fixedly connected to the upper part of the first mold 35 and the second mold 37, so that they can both be subjected to force. One end of the connecting rod 313 is detachably connected to the lower end of the rotating shaft 28, and the retaining ring 310 is fixedly connected to the lower end of the connecting rod 313, and the connecting rod 313 drives the retaining ring 310 to rotate. The retaining ring 310 is fan-shaped and hollowed out, so that concrete can pass through the retaining ring 310. The stop block 311 is fixedly connected to the outer side of the retaining ring 310.
[0023] The second electric cylinder 33 has two fixed connections on both sides of the first outer protective shell 31, and one side of the abutment plate 34 is fixedly connected to the second outer protective shell 32. The second electric cylinder 33 pushes the abutment plate 34 to separate the first outer protective shell 31 from the second outer protective shell 32. One end of the slide bar 36 is fixedly connected to the abutment plate 34, and the other end of the slide bar 36 is slidably connected to the first outer protective shell 31. Both sides of the upper end of the fixed frame 1 are connected to the slide groove 9, and the upper ends of the first outer protective shell 31 and the second outer protective shell 32 are connected to the moving plate 10, and one side of the moving plate 10 is connected to a plurality of rollers 11, and the plurality of rollers 11 are rollingly connected to the slide groove 9. The lower parts of the first outer protective shell 31 and the second outer protective shell 32 are connected to the slide rail 14, and the lower parts of the first mold 35 and the second mold 37 are connected to the sliding block 15, and the sliding block 15 is slidably connected to the slide rail 14. The upper ends of the first outer protective shell 31, the second outer protective shell 32, the first mold 35 and the second mold 37 are all connected with a feed port 7, and the feed port 7 is connected with a connecting pipe 8. The connecting pipe 8 is made of flexible material to prevent the flexible pipe from breaking. A through groove 13 is provided at the lower part of the first outer protective shell 31 and the second outer protective shell 32, so that the through groove 13 can be inserted to fix the first outer protective shell 31 and the second outer protective shell 32. A reinforcement block 12 is connected to the outside of the first outer protective shell 31 and the second outer protective shell 32, and the first mold 35 and the lower part of the second mold 37 are connected with the reinforcement block 12, which can be fixed by bolts passing through the reinforcement block 12.
[0024] The working principle of the above scheme is as follows: the first electric cylinder 4 drives the traction rope to move, and at this time the first outer protective shell 31 and the second outer protective shell 32 move to the bottom of the rotating shaft 28. The bolt (not shown in the text) is turned to loosen the reinforcement block 12, and at this time the second electric cylinder 33 is started to separate the first outer protective shell 31 and the second outer protective shell 32, and at this time the connecting rod 313 is spliced under the rotating shaft 28. At this time, the reinforcement block 12 is penetrated by bolts to close the first outer protective shell 31 and the second outer protective shell 32, and at this time the reinforcement block 12 at the bottom of the first mold 35 and the second mold 37 is fixed. When concrete falls into the first mold 35 and the second mold 37, the motor 22 rotates to drive the rotating shaft 28 to rotate, and the rotating shaft 28 drives the connecting rod 313 to rotate, and the connecting rod 313 rotates the retaining ring 310 so that the stop block 311 conflicts with the protrusion 312. At this time, the first mold 35 and the second mold 37 are swung left and right, and the first mold 35 and the second mold 37 can be reset through the telescopic rod 39 and the spring 38, so as to move back and forth. At this time, the bubbles in the concrete can be discharged, and the strength of the concrete is improved. When the concrete is poured, the bolts are turned to loosen the reinforcement block 12, and the second electric cylinder 33 is started to push the plate 34. At this time, the first outer shell 31 and the second outer shell 32 are separated, and the finished product is taken out.
[0025] The above scheme has the beneficial effects as follows: the motor 22 drives the rotating shaft 28 to rotate, so that the connecting rod 313 drives the retaining ring 310 to rotate, and the stop block 311 on the retaining ring 310 conflicts with the protrusion 312, so that the first mold 35 and the second mold 37 swing left and right, and the first mold 35 and the second mold 37 can be reset by the telescopic rod 39 and the spring 38; the retaining ring 310 is fan-shaped so that the stop block 311 conflicts with the protrusion 312 at the first mold 35, and the second mold 37 and the protrusion 312 move toward the retaining ring 310. At this time, the retaining ring 310 rotates the stop block 311 to conflict with the protrusion 312 on the second mold 37, so that the first mold 35 and the second mold 37 swing left and right, and the bubbles in the concrete are discharged; the first electric cylinder 4 pulls the clamping device 3 to move, so that multiple clamping devices 3 can slide on the fixed frame 1 to adjust the orientation.
