Plastering-free concrete block grooving equipment

The invention relates to the technical field of building block grooving, and discloses plastering-free concrete building block grooving equipment which comprises a conveying belt, a round roller arranged on the conveying belt and a driving motor, and further comprises a feeding assembly arranged at the top of the conveying belt and used for intermittently transferring concrete building blocks; the circulating grooving assembly is arranged above the conveying belt, and the circulating grooving assembly is used for grooving the concrete blocks; and the clamping and fixing assemblies are arranged at the top and the bottom of the conveying belt, and the clamping and fixing assemblies are used for clamping the concrete blocks to be slotted. Different cutting discs can be used when two continuous concrete blocks are grooved, the concrete blocks can be automatically clamped during grooving, clamping of the concrete blocks can be automatically relieved after grooving of the concrete blocks is completed, the concrete
