Anti-breaking grooving machine for construction site

The invention discloses an anti-breaking grooving machine for a construction site. The anti-breaking grooving machine for the construction site comprises an installing bottom plate; a water tank and acutting motor are fixedly connected to the upper surface of the installing bottom plate; a water leaking pipe is fixedly connected in the installing bottom plate; one end of the water leaking pipe communicates with the inner bottom wall of the water tank; and the other end of the water leaking pipe extends to the exterior of the installing bottom plate. The anti-breaking grooving machine for theconstruction site achieves the effect of performing twisting force adjustment on a cutting rotating shaft, when the twisting force borne by the cutting rotating shaft is large, an adjusting rod disengages from the inner wall of an adjusting groove to continue to rotate, and after rotating is performed by a circle, the adjusting rod is connected with the inner wall of the adjusting groove again inan inserted manner; and when the twisting force borne by the cutting rotating shaft is still large, the adjusting rod repeats the above action, at the moment, the installing bottom plate can be pushedbackwards properly, then the cutting rotating shaft can continue to rotate, then the feeding amount is adjusted, and therefore the problem that because the material hardness is not uniform, a cuttingblade is damaged easily is effectively solved.
