Description

Technical Field

[0001] The utility model relates to the technical field of gelling detection equipment, in particular to an automatic tester for gelling material coagulation time. Background Art

[0002] Cementitious materials, also known as cementing materials, can be transformed from slurry into a solid stone-like body under physical and chemical effects, and can be cemented with other materials to make composite solid substances with certain mechanical strength. The setting time is used to test the time it takes for cementitious materials to change from slurry to solid, which is convenient for the staff who use the material to control the setting time.

[0003] In the prior art, after completing a test, the material tray is usually disassembled, cleaned, and then installed, which wastes a lot of time and reduces the measurable amount per day to a certain extent.

[0004] The utility model patent with authorization announcement number CN218601285U discloses an automatic tester for the setting time of cementitious materials, including a base, a box body is fixedly connected to the top of the base, a servo motor is fixedly connected to the bottom of the inner wall of the box body, a No. 1 gear is fixedly connected to the output end of the servo motor, a rotating shaft is rotatably connected to the top of the box body, the bottom of the rotating shaft extends to the inside of the box body and is fixedly connected to the No. 2 gear, the No. 1 gear is meshed with the No. 2 gear, a connecting plate is fixedly connected to the top of the rotating shaft, a material tray is connected to the top of the connecting plate by screws, a vertical plate is fixedly connected to one end of the top of the box body, a through groove is opened inside the vertical plate, and a screw rod is rotatably connected inside the through groove. When the equipment completes a test, the material tray needs to be cleaned. The lead screw is controlled to rotate to drive the slider to slide inside the through slot, thereby driving the rotating rod to move. At the same time, the rotating rod is fixed to the position of the inner wall of the material tray through the second nut. The servo motor is controlled to rotate to drive the No. 1 gear, thereby driving the No. 2 gear, and then driving the connecting plate to rotate, which can drive the material tray to rotate. With the cooperation of the rotating rod and the brush, the inner wall of the material tray is cleaned, saving the time of frequent disassembly and cleaning, and increasing the measurable amount in a day.

[0005] The above technical solution solves the problem that after completing a test in the prior art, the material tray is usually disassembled, cleaned, and then installed, which wastes a lot of time and reduces the amount that can be measured every day to a certain extent. However, when the device is cleaned, the material tray rotates for cleaning, and the water inside is easily thrown out, causing pollution to the environment around the material tray.
