Description

Technical Field

[0001] The utility model relates to the technical field of mortar detection equipment, in particular to a mortar viscosity detector. Background Art

[0002] In the field of construction, in order to determine the proportion of cement mortar and achieve the purpose of controlling water consumption, it is usually necessary to test the consistency of cement mortar. The consistency of mortar is the depth of a standard cone that sinks into the mortar mixture within a specified time, expressed in mm. The deeper the cone sinks, the greater the consistency and the better the fluidity. The current detector includes a bracket, a hopper set at the bottom of the bracket, and a sliding frame located above the hopper, and also includes a cone, on which a sliding rod is coaxially fixed, and the sliding rod is slidably connected to the sliding frame. When in use, the cement mortar to be tested is injected into the hopper, and then the surface of the cement mortar is tamped flat with a tamping rod; finally, the tip of the cone is brought into contact with the surface of the cement mortar, so that the cone moves downward under the action of gravity, and the sinking degree is measured to obtain the viscosity of the cement mortar. Currently, cement mortar in the hopper is usually vibrated manually using a tamping rod, which puts a lot of labor intensity on the workers and makes it difficult to make the surface of the cement mortar smooth. In addition, the existing mortar viscosity detection equipment has insufficient cone settling smoothness and is easily affected by friction resistance, which affects the detection accuracy.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions.
