In order to enable the piston rod 5 to carry the piston 9 to realize automation when the piston rod 5 carries out the action, as shown in fig. 2 and 5, in order to enable the trigger protrusion 8 to form a movable space when the piston rod 5 is pushed to act, the size of the movable groove 7 is larger than the outline size of the trigger protrusion 8, a guide ring 22 close to the annular groove 19 is arranged on the mechanical arm 1, a rotating sleeve 23 capable of rotating around the circumferential direction is arranged in the guide ring 22, a trigger rod 24 is arranged on the outer wall surface of the rotating sleeve 23, the trigger rod 24 horizontally extends to exceed the connecting seat 3 along the periphery of the mechanical arm 1, and a fixing plate 25 for fixing the trigger rod 24 on an anchor driving machine is arranged at the extending terminal end of the trigger rod 24, so that the trigger rod 24 is fixed on the periphery of the mechanical arm 1 and does not affect the normal rotation action of the mechanical arm 1, and in addition, as a hydraulic pressure block 27 matched on the outer side of the trigger protrusion 8 is also fixed on the trigger rod 24, when the trigger protrusion 8 rotates to be close to the trigger rod 24 to be contacted with the trigger protrusion 8, the trigger protrusion 8 is extruded to move from the movable groove 7 and push the trigger protrusion 5 to drive the piston 9 to finish the pressing block action of the clear water in the main liquid cavity 6. Through this kind of circumference direction's transmission mode, first utilized connecting seat 3 relative pivoted characteristic for the rotation momentum of tunnelling rotation motor can directly be used to whole structure, need not peripheral hardware drive part, and the second aspect is that circumference direction's transmission mode makes the transmission smoother, and motion stroke and compression volume are fixed, improves structural stability, and the third aspect is that circumference direction is to lead the mode of driving can guarantee that the atress direction is not axial, reduces the axial bearing of structure. From the above, it can be seen that the power source when the piston rod 5 mounted on the mechanical arm 1 acts is derived from the squeezing action generated by the pressing block 27 on the trigger lever 24 and the trigger protrusion 8, and the specific contact principle is as follows: after the use of the tunneling and anchoring machine, wet mud possibly attached to the tunneling drill bit 2 and the anchor cone 15 needs to be cleaned, the tunneling and anchoring machine rotates in an idle mode (does not carry out mining operation) and drives the mechanical arm 1 to rotate by utilizing a rotating mechanism of the tunneling and anchoring machine, a trigger rod 24 positioned on the outer side of the tunneling and anchoring machine is fixed with a pressing block 27 on the trigger rod 24, when the mechanical arm 1 is driven to bring a trigger bulge 8 on the piston rod 5 into contact with the pressing block 27, a cam contact surface 28 on the pressing block 27 is contacted with an inclined surface 29 on the trigger bulge 8, the pressing block 27 is fixed, the trigger bulge 8 needs to rotate along with the mechanical arm 1 by the piston rod 5, therefore, according to the cam contact principle, the trigger bulge 8 moves leftwards in a right direction in the drawing due to the extrusion of the pressing block 27, the piston rod 5 pushes the piston 9 to complete hydraulic work in the main liquid cavity 6, the volume of the main liquid cavity 6 is forced to be reduced, water pressure is formed, water is sprayed out from the spray hole 13, and finally automatic cleaning operation is carried out from the spray hole 18 on the anchor cone 15 against the tunneling drill bit 2 and the anchor cone 15, the mechanical arm 1 is driven to continuously rotate with the piston rod 5, the trigger bulge 8 on the piston rod 5 is forced to be separated from the pressing block 27, at the moment, the trigger bulge 8 is not pressed any more, the piston rod 5 is reset again under the action of the elastic force released by the spring 14 until the next rotation period, the next hydraulic water spraying operation is carried out again when the trigger bulge 8 is contacted with the pressing block 27 again, therefore, the power of the hydraulic operation is derived from linkage operation generated by the mechanical arm during rotation operation, the design is ingenious, the mechanical arm can also rotate with the drill bit during cleaning, the wet mud attached to the anchor cone can be cleaned while rotating to further improve the cleaning efficiency.
The pressing block 27 is vertical downwards from the trigger rod 24, a cam contact surface 28 is arranged at the vertical bottom end of the pressing block 27, and an inclined surface 29 matched with the cam contact surface 28 is arranged at the outer end of the trigger protrusion 8, and the specific principle is as follows: a plurality of rollers 33 are arranged in the guide ring 22 of the trigger rod 24 along the circumferential direction, the rotating sleeve 23 is arranged on the rollers 33, the rotating sleeve 23 is fixed to the anchor driving machine along with the fixed plate 25 at the terminal end of the trigger rod 24, and the mechanical arm 1 is in rotary motion, so that the rotary motion of the mechanical arm 1 is not influenced by the rolling principle between the rollers 33 and the rotating sleeve 23.
