Drilling and grouting anchor trolley grouting system and control method thereof

The invention discloses a grouting system of a drilling and grouting anchor trolley and a control method of the grouting system. The grouting system comprises a control module and an execution module. The control module is connected with the execution module; the execution module comprises a stirring unit, a slurry storage unit and a spiral pressurizing unit, and the stirring unit is connected with the slurry storage unit through a slurry conveying pipe; one end of the spiral pressurizing unit is connected with the lower part of the slurry storage unit, and the other end of the spiral pressurizing unit is connected with the stirring unit sequentially through a header pipe cavity and a circulating pipeline; and the main pipe cavity is connected with a water pipe through a water valve and is also connected with a slurry outlet pipe through a slurry outlet valve. According to the system, mixed slurry can be prevented from being hardened in the process that the drilling, grouting and anchoring trolley breaks down
