[0029] The utility model discloses a piston block 3 lower surface installs the conical extrusion block 33, realizes more efficient thorough slurry discharge. When piston block 3 pushes slurry to the lowest position of grouting cylinder 1, conical extrusion block 33 just with the inner wall of conical slurry outlet 2 is attached, thereby effectively extruding the surplus slurry in conical slurry outlet 2, ensure that slurry can be discharged thoroughly.

[0030] The utility model discloses a trowel plate 10 is arranged at the both sides of grouting cylinder 1, make the construction personnel when carrying out grouting, can smoothly complete the operation of collecting and troweling, thereby remarkable time and manpower are saved, improve work efficiency. Specifically, in the grouting process, the bottom surface of trowel plate 10 is closely attached with the ground of grouting position, when the construction personnel moves grouting cylinder 1, trowel plate 10 will also move synchronously, realizes the synchronous operation of grouting and collecting and troweling. This design not only improves the convenience of construction, also effectively reduces unnecessary repeated work.

[0031] Specifically, since in actual grouting operation, the construction personnel will incline grouting cylinder 1 proper angle, thereby facilitating grouting operation. At this time, the construction personnel can rotate rotary disc 6 according to the inclination angle of grouting cylinder 1, thereby reach the purpose of adjusting the angle of trowel plate 10 and grouting cylinder 1, so that grouting cylinder 1 is in the state of inclination, and the bottom surface of trowel plate 10 is still in the state of attachment with the grouting position.

[0032] Specifically, by adjusting the overall length of horizontal telescopic rod 8, the distance between trowel plate 10 and conical slurry outlet 2 can be changed, thereby meeting different construction requirements. By adjusting the inclination angle of trowel plate 10 and elastic telescopic rod 9, trowel plate 10 can be inclined to facilitate the operation of collecting and troweling. Through the setting of elastic telescopic rod 9, the bottom surface of trowel plate 10 can always elastically abut on the upper surface of the grouting position, so as to exert a certain elastic external force during the operation of collecting and troweling, and ensure the quality requirement of collecting and troweling.

[0033] Further, the upper surface of the conical extrusion block 33 is provided with a threaded groove 331, and the lower surface of the piston block 3 is fixedly connected with a short threaded column 34, and the short threaded column 34 is threadedly connected in the inside of the threaded groove 331.

[0036] Specifically, when the construction personnel pulls the piston rod 31 and the piston block 3 up and down through the pull ring 32, the air holes 42 can effectively provide the required airflow for the inside of the grouting tube 1 and the top of the piston block 3. The polygon ring seat 43 is arranged so that the construction personnel can more conveniently disassemble the end cover 4 during maintenance or replacement, improving the efficiency and convenience of construction.

[0037] Further, the surface of the rotating disc 6 is symmetrically provided with two groups of arc-shaped grooves 61, the fixing member 7 includes two groups of long threaded columns 71, which are fixedly connected to the side of the C-shaped buckle 5 away from the opening and respectively located on the left and right sides of the connecting column 51, and are movably connected to the inner sides of the two groups of arc-shaped grooves 61, respectively. The outer side of the long threaded column 71 is threadedly sleeved with a nut 72, which abuts against the side of the rotating disc 6 away from the connecting column 51.

[0038] Specifically, when it is necessary to change the inclination angle between the trowel plate 10 and the grouting tube 1, the two groups of nuts 72 can be loosened, and at this time the long threaded columns 71 can slide relatively in the arc-shaped grooves 61. Subsequently, by rotating the rotating disc 6, the inclination angle between the trowel plate 10 and the grouting tube 1 can be effectively adjusted. After adjustment, the construction personnel only needs to tighten the nuts 72 again so that they abut against one side of the rotating disc 6, so that the rotating disc 6 and the C-shaped buckle 5 cannot rotate relatively, thereby ensuring that the position between the trowel plate 10 and the grouting tube 1 remains stable and unchanged.

[0040] Specifically, when it is necessary to adjust the overall length of the transverse telescopic rod 8, the short bolt 822 only needs to be loosened, and at this time the H-shaped rod 81 and the L-shaped rod 82 can slide relatively to conveniently adjust their relative positions. After adjustment, the short bolt 822 is tightened again so that it abuts against the H-shaped rod 81, thereby ensuring that the overall length of the transverse telescopic rod 8 remains stable.

[0041] Further, the elastic telescopic rod 9 includes a sleeve 91 and a movable rod 93, the sleeve 91 is fixedly connected to the lower end of the vertical edge of the L-shaped rod 82, the inside of the sleeve 91 is fixedly connected with a spring 92, and the movable rod 93 is fixedly connected to the lower end of the spring 92 and slidably connected to the lower inside of the sleeve 91.

[0042] Specifically, during the grouting process, the trowel plate 10 can always be in a state of close contact with the ground at the grouting position under the action of the elastic telescopic rod 9. This elastic structure not only improves the flexibility of operation, but also effectively adapts to the uneven ground.

[0043] Further, the lower end of the movable rod 93 is fixedly connected with a rotating seat 94, and the upper surface center position of the trowel plate 10 is fixedly connected with an ear plate 101, which is rotationally connected in the interior of the rotating seat 94 and is fixed by a bolt.

[0044] Specifically, when it is necessary to adjust the inclination angle of the trowel plate 10, the bolt used to fix the ear plate 101 and the rotating seat 94 is only loosened, and then the inclination angle of the trowel plate 10 can be adjusted. After the adjustment is completed, the bolt is tightened again, so that the trowel plate 10 can be kept at the required inclination angle.

[0045] The above is only the preferred embodiment of the present application, and is not used to limit the present application. It should be pointed out that, for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection scope of the present application.
