In this embodiment, the driving member 136 is a compression spring, one end of which is connected to the cylinder body of the buffer cylinder 130, and the other end of which is connected to the buffer piston 132. In other embodiments the driving member 136 may be a tension spring disposed within the buffer space.
The buffer space 134 of the buffer cylinder 130 is connected to the second pressure cylinder 120 via an output pipe 140, either directly or indirectly via an intermediate element. For example, the output pipe 140 may be connected to a pipe between the buffer cylinder 130 and the first pressure cylinder 110, or the output pipe 140 may be also connected to a compression space of the first pressure cylinder 110; the connection mode is indirect connection.
The driving device 150 is used for driving the first driving rod 118 to be matched with the second driving rod 128, so that the movement direction of the first piston 116 and the movement direction of the second piston 126 are opposite. Moreover, by properly designing the dimensions of the related components, a person skilled in the art can make the second piston 126 capable of sealing the connecting pipe 170 when the negative pressure is generated in the first pressure cylinder 110.
As shown in fig. 1, 2 and 3, the driving device 150 includes a driving wheel 151, a bracket 152 and a prime mover 152, and the driving wheel 151 is rotatably connected to the bracket 152 through a rotation shaft 154.

As shown in fig. 1 and 4, the working principle of the pressure grouting machine 100 provided in the present embodiment is as follows:
in use, slurry is first stored in the storage tank 120. The drive means 150 is activated and the first piston 116 is moved in a direction away from the first closed end 112, i.e. in the direction of the arrow in fig. 1. At this time, the movement direction of the second piston 126 is opposite to the movement direction of the first piston 116, i.e., the arrow direction in fig. 1. And the second piston 126 seals off the outlet of the connecting conduit 170 so that a negative pressure is created in the first pressure cylinder 110 that causes slurry to enter the first pressure cylinder 110 from the storage tank 120.
When the first piston 116 starts to move in a direction approaching the first closed end 112 after moving to the extreme position, the second piston 126 also reverses direction, i.e. moves in a direction away from the second closed end 122, i.e. in the direction of the arrow in fig. 4. At this time, positive pressure is generated in the first pressure cylinder 110, and the second piston 126 is also blocking the connecting pipe 170, so that the slurry enters the buffer cylinder 130 for temporary storage. When the second piston 126 continues to move to a position where it no longer blocks the connecting conduit 170, the slurry in the buffer cylinder 130 and the first pressure cylinder 110 enters the second pressure cylinder 120. When the direction of movement of the first piston 116 and the second piston 126 is reversed, positive pressure is generated in the second pressure cylinder 120, and the slurry is extruded to the delivery pipe for output.
The pressure grouting machine 100 obtained through the design has high automation degree, so the maintenance cost is low, and the efficiency is high.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
