[0157] In the actual application process of the embodiment, when the controller 10 detects that the inlet pressure of the grouting pump 7 drops to the normal range, the connecting pipe 6 is blocked. Since there is a gap between the inlet diameter of the connecting pipe 6 and the amount of material in the storage cylinder, and the connecting pipe 6 may be blocked by the adhesion and accumulation of mortar deposits, the staff needs to control the extension of the electric rod 46, so that the electric rod 46 pushes the elastic rod 50 downward by using the telescopic end, so that the elastic rod 50 is bent and deformed under the action of the external force by using the guiding and resisting action of the arc hole rod 48, and moves along the guide pipe 49 to the inside of the connecting pipe 6. In the process, the elastic rod 50 will pull the spring leaf 51 to deform and expand under the action of the guide of the guide pipe 49 and the moving external force, so that the spring leaf 51 gradually stretches and stores energy. When the electric rod 46 is fully extended, the sharp end of the elastic rod 50 will be inserted into the connecting pipe 6, thereby pushing the blocked mortar in the connecting pipe 6. At the same time, the electric rod 46 will pull the drawstring 58 by using the telescopic end during the extension process, so that the drawstring 58 moves downward along the through hole 57 by penetrating the perforation 56, thereby enabling the drawstring 58 to pull the T plate 53 by using the external force, so that the T plate 53 moves downward under the guidance of the T groove 52 while driving the pressure plate 54. At the same time, the T plate 53 will bend and deform and store energy by cooperating with the elastic sheet 55 during the downward movement.

After the electric rod 46 is fully extended, the inclined surface of the inclined push plate 60 moves to the side surface of the elliptical rod 68, thereby enabling the inclined push plate 60 to push the elliptical rod 68 to move downward during the counterclockwise rotation of the tooth block 33 and the N ring 30 by using the inclination angle of the inclined push plate 60 and the arc of the elliptical rod 68, so that the elliptical rod 68 can drive the hammer rod 67 to move downward by penetrating the guide cylinder 64, so that the lower end of the hammer rod 67 can contact and strike the connecting pipe 6. At the same time, the hammer rod 67 will press the second spring 66 to contract and store energy by using the blocking ring 65. When one of the inclined push plates 60 passes through the elliptical rod 68, the second spring 66 will rebound under the support of the guide cylinder 64, and push the hammer rod 67 and the elliptical rod 68 upward by using the blocking ring 65, so that the hammer rod 67 is separated from the connecting pipe 6. After that, the N ring 30 will push the elliptical rod 68 by using the next inclined push plate 60, thereby enabling the hammer rod 67 to move up and down reciprocatingly to strike the connecting pipe 6, so that the connecting pipe 6 vibrates to promote the flow of the blocked mortar in the connecting pipe 6, thereby preventing blockage.

[0158] After the electric rod 46 is retracted and reset, the elastic sheet 55 will push the T plate 53 and the pressure plate 54 upward to reset by using the rebound force, and the first spring 62 will push the blocking disc 61 and the inclined push plate 60 upward to reset by using the rebound force. During the resetting process of the T plate 53, the drawstring 58 will be pulled and moved to reset at the same time.

[0159] The above is the preferred embodiment of the present application, it should be noted that for those skilled in the art, without departing from the principles described in the present application, can also be made several improvements and refinements, these improvements and refinements should also be considered the scope of protection of the present application.
