Description

Technical Field

[0001] The utility model relates to the technical field of cement mortar experiments, in particular to a cement mortar vibrating table which is easy to clean. Background Art

[0002] In the preparation of samples used for cement strength testing, cement and mortar need to be mixed and then vibrated. The cement mortar vibrating table can drive the test mold platen and the cement mortar installed in the test mold platen to rise, and then fall. When the test mold platen rises to a fixed position, it suddenly drops and falls to its original position. At the original position, the cement mortar is vibrated due to the inertia of the descent. Currently, the common vibrating tables lack sealing covers and make a lot of noise during use. At the same time, after placing the mold on the table, the user needs to fix the mold by pressing down. Excessive downward pressure can easily cause the mold to slip, causing the concrete inside the mold to tilt during the later vibration process. For this reason, a cement mortar vibrating table that is easy to clean is proposed. Utility Model Content
