when grouting is performed, the second rotating shaft 702 rotates, the rotation of the second rotating shaft 702 causes the lug 1002 to sequentially abut against the lower end of the push rod 1003, the moving plate 1001 to reciprocate up and down under the action of the second reset mechanism, the moving plate 1001 drives the sliding rod 908 to reciprocate up and down when reciprocating up and down, when the sliding rod 908 moves down, negative pressure is generated in the second fixed pipe 904, meanwhile, the fourth spring 1203 is compressed, the first one-way valve is opened, the second one-way valve is closed, air is extracted through the air extraction pipe 902 at the moment, when the sliding rod 908 moves up under the action of the fourth spring 1203, air in the second fixed pipe 904 is extruded, the first one-way valve is closed, the second one-way valve is opened, at the moment, the air in the second fixed pipe 904 is exhausted through the air exhaust pipe 906, and air between the grouter body 1 and the pile hole is exhausted, the defects of air holes and the like generated after grouting are avoided, the grouting quality is ensured, and the push rod 1003 can vibrate the grout when moving up and down in a reciprocating manner, so that the grouting effect is better;
and, when rack 302 moves to the direction of keeping away from sealing plate 203, make sealing plate 203 open to the rotation of protection box 201, and meanwhile, rack 302's removal drives limiting plate 505's removal, make limiting plate 505 slide at first inclined plane 504 lateral wall, make stopper 502 retract in the bar opening 601, and simultaneously, second spring 605 contracts, after limiting plate 505 crossed first inclined plane 504, second spring 605 makes stopper 502 stretch out, and, can make the lateral wall of spacing face 503 and limiting plate 505 offset, thereby the direction removal that the restriction rack 302 is close to grout outlet 202 resets, guarantee sealing plate 203 rotate open the back promptly, can not make it rotate to reset and close on sealing plate 203 because of the thick liquid strikes, guarantee the normal clear of grout.
