Abstract

The invention relates to the technical field of cement test equipment, in particular to a cleaning and protecting device for a cement anti-fracture testing machine. The cleaning and protecting devicecomprises a protective cover, an opening and a closing plate are arranged on one side of the protective cover, a first elastic element is arranged at the position of the opening, a support is fixed tothe base, a driven roller and a traction rope are arranged on the support, a spiral groove is formed in the side wall of the driven roller, a driving roller is fixed to the end of a main screw rod, and the same belt is tightly wound around the driving roller and the driven roller. A main motor is started to enable the main screw rod to rotate, the main screw rod drives a moving weight to move andcause the driving roller to rotate, the driven roller rotates and causes the traction rope to be gradually embedded into the spiral groove, the pulling rope pulls the closing plate to rotate and closethe opening, and waste chips generated by a workpiece are blocked; and then the main screw rod and the driving roller rotate to fall, the belt loosens, and the first elastic element drives the closing plate to rotate, so that the opening is exposed. The cleaning and protecting device reduces the occurrence of potential safety hazards and facilitates the cleaning and collection of the waste chips.
