[0011] Preferably, the extrusion plate is fixed with a feeding column on the side close to the discharge plate; the feeding column is arranged in correspondence with the hole on the surface of the discharge plate. By arranging the feeding column in correspondence with the hole, when the extrusion plate is close to the discharge plate, the feeding column will contact the inner side of the hole, thereby pushing the residual cement paste out of the inner side of the hole, preventing the hole from being blocked.

[0023] The bottom surface of the gear 604 and the top surface of the contact disc 607 are respectively provided with grooves and protrusions, and the grooves and the protrusions are arranged in a plurality of annular equiangular uniform distribution; the grooves and the protrusions are matched with each other, the toothed plate 606 is engaged with the outer side of the gear 604; one side of the bottom surface of the sliding plate 601 is fixedly connected to the upper surface of the toothed plate 606; the two ends of the toothed plate 606 and the sliding plate 601 pass through the mounting box 8 and extend to the outer side; the connecting block 602 is fixedly connected to the top surface of one end of the sliding plate 601, and the upper end of the connecting block 602 is fixedly connected to the outer surface of the plugging sleeve 14.

[0024] The extrusion plate 12 is fixedly connected to the side close to the discharge plate 11, and the discharge column 13 is fixedly connected to the side close to the discharge plate 11; the discharge column 13 is arranged in a plurality of corresponding holes arranged on the surface of the discharge plate 11, the outer side of the plugging sleeve 14 is in contact with the inner side of the grouting barrel 1, and the outer side of the plugging sleeve 14 is arranged in a smooth shape; the outer side upper surface of the grouting barrel 1 is fixedly connected with the connecting pipe 9, and the connecting pipe 9 is in communication with the grouting barrel 1 through the feeding port; the pulling handle 10 is fixedly installed on the top surface of one end of the grouting barrel 1 close to the feeding port.

[0025] The limiting column 603 is slidingly connected to the inner side of the connecting block 602, and the two ends of the limiting column 603 pass through the connecting block 602 and are fixedly connected to the inner surface of the communication slot 20; the outer side of the limiting column 603 is sleeved with a threaded spring, and the two ends of the threaded spring are fixedly connected to the connecting block 602 and the side of the communication slot 20 away from the rotating disc 17; the outer surface of the rotating rod 2 is fixedly connected with the threaded leaves 3, and the threaded leaves 3 are arranged in a plurality of uniform distribution.

[0026] Working principle: in use, first put the cement slurry in the cement tank to deploy, and then connect the outlet of the cement tank with the grouting barrel 1 through the connecting pipe 9. Because the cement tank is high, the cement slurry will flow into the inside of the grouting barrel 1 through the connecting pipe 9. Then the user holds the pull handle 10 and pulls the grouting barrel 1, so that the output port of the grouting barrel 1 is aligned with the gap. Then start the motor to drive the rotating disc 17 to rotate. When the rotating disc 17 rotates, the rotating sleeve 15 drives the plurality of pin rods 16 to rotate at the same time. When the rotating sleeve 15 drives the plurality of pin rods 16 to rotate, it drives the pin wheel 611 engaged therewith to rotate forward. When the pin wheel 611 rotates, it drives the upper fixed column 610 to rotate as well. At this time, the fixed column 610 will drive the contact disc 607 to rotate through the cooperation of the internal polygonal groove and the multi-edge column 608. The contact disc 607 in the rotating state will make the protrusions on the top surface of the contact disc 607 contact the recesses on the bottom surface of the gear 604 under the pushing of the compression spring, thereby driving the gear 604 to rotate forward as well. Since the gear 604 is engaged with the tooth plate 606, it will push the tooth plate 606 to move towards the output port of the grouting barrel 1. When the tooth plate 606 moves, it will drive the blocking sleeve 14 to move towards the output port of the grouting barrel 1 through the connecting block 602 on the surface. At this time, the threaded spring will be gradually compressed to store energy under the movement of the connecting block 602. When the blocking sleeve 14 moves, it will push the extrusion plate 12 to move to block the connecting pipe 9 at the upper end of the grouting barrel 1, preventing the squeezed cement slurry from flowing back into the cement pipe. When the extrusion plate 12 moves, it will squeeze the cement slurry to contact the discharge plate 11. At this time, part of the cement slurry will flow into the other side of the grouting barrel 1 through the holes on the surface of the discharge plate 11 and contact the threaded leaf 3. After the cement slurry is squeezed and flows out from the holes, the internal bubbles will be broken, thereby improving the density of the cement slurry. When the extrusion plate 12 contacts the discharge plate 11 during movement, the feeding column 13 will contact the holes, thereby pushing out the residual cement slurry in the holes to prevent the holes from being blocked. When the extrusion plate 12 contacts the tooth plate 606, the tooth plate 606 will be stopped from moving, thereby stopping the gear 604 engaged therewith from rotating. When the gear 604 stops rotating, the protrusions on the top surface of the contact disc 607 will be subjected to a large pressure, thereby sliding on the bottom surface of the gear 604 away from the recess. At this moment, the threaded spring outside the limiting column 603 will burst without being limited, thereby driving the extrusion plate 12 to reset through the connecting block 602. After resetting, the protrusions and the recesses will be in contact again under the pushing of the extrusion spring, thereby driving the extrusion plate 12 to be squeezed again. The extrusion plate 12 moves back and forth repeatedly. When the rotating disc 17 rotates, the rotating rod 2 is also rotated, and when the rotating rod 2 rotates, the scraper 4 is also rotated through the connecting plate 5, so that the scraper 4 in the rotating state scrapes the cement mortar adhered to the inner side of the grouting barrel 1 away from the contact with the grouting barrel 1, reducing the problem of blockage of the cement mortar adhered to the inside of the grouting barrel 1. When the rotating rod 2 rotates, the threaded blade 3 is also rotated in the forward direction. The threaded blade 3 in the rotating state stirs the cement mortar, so that the cement mortar is mixed more uniformly. In the process of stirring, the contacted cement mortar is transmitted to the grouting barrel 1 through the surface thread, and comes out of the discharge port to fill the gap. After the gap is filled, clean water is injected into the grouting barrel 1 to clean the grouting barrel 1.
