Description

A digital display mortar consistency measuring device

technical field

The utility model relates to the technical field of testing instruments and equipment, in particular to a digital display mortar consistency measuring device.

Background technique

The mortar consistency meter is used to measure the fluidity of the mortar. The general fluidity is also called the consistency. The consistency of the mortar is to use a standard cone with a certain geometric shape and weight to sink freely into the mortar mixture by its own weight. In terms of depth, the mortar must have good workability before hardening, including fluidity, and a large sinking amount indicates good fluidity. The existing mortar consistency tester is complicated to operate and takes a long time in the measurement process. During the operation, the brake screw must be rotated several times and the rack adjusted, so that the slurry container is put into the base and the tip of the test cone just touches the mortar. Vibration will inevitably occur on the surface, which will affect the state of the mortar. When the test cone is lowered, due to the different operating habits of different operators, the speed of rotating the brake screw is different, the friction force on the slide bar is different when the cone is lowered, and the speed of the slide bar is different, so that the data measured by different personnel are quite different. . Since the scale of the dial can only be accurate to one millimeter, the measurement accuracy is low, which is not conducive to the subsequent tests such as the degree of delamination. Therefore, we improve this and propose a digital display mortar consistency measurement device.
