Description

Technical Field

[0001] This utility model relates to the field of wet mortar sampling technology, specifically to a multi-level sampling device for wet mortar. Background Technology

[0002] During the production and use of wet-mixed mortar, sampling and testing are necessary to ensure quality. However, most existing sampling devices can only sample a single layer of wet-mixed mortar in the storage tank, making it difficult to obtain mortar samples at different depths and heights. This results in insufficient sample representativeness and affects the accuracy of test results. Furthermore, after sampling, mortar residue easily remains in the sampling pipes, making cleaning inconvenient. This not only affects the accuracy of subsequent sampling but may also cause pipe blockages, creating operational difficulties. Utility Model Content

[0040] Working principle:

[0041] Sufficient clean water is pre-stored in the water storage tank 105.

[0042] When it is necessary to perform multi-layer sampling and testing of the wet-mixed mortar in the storage tank body 101 (the post-sampling testing is an existing mature technology), the sampling motor 405 is started. The sampling motor 405 drives the reducer 404, which drives the sampling shaft 402 to rotate, thereby driving the sampling spiral blade 403 to rotate. At the same time, the wet-mixed mortar in the storage tank body 101 at different layer positions enters the sampling buffer chamber 401 through the injection port. Driven by the sampling spiral blade 403, it gradually moves towards the output channel 406 until it enters the semi-circular conveying channel for output. The first connecting joint 407 can be connected to an external collection bucket through a hose (a valve that can be set on the first connecting joint 407 for opening and closing) After sampling is completed, the sampling motor 405 is turned off, and then the first valve 108 is opened, so that the clean water in the water storage tank 105 enters the corresponding cleaning buffer chamber 410 through the water supply pipe 109, and then enters the output channel 406 through the cleaning pipe 411 to rinse the output channel 406 and the first connecting joint 407 (rinsing time is 4-5 seconds, and the first valve 108 is closed after rinsing to avoid the valve at the first connecting joint 407 being obstructed during the closing process).

[0043] The wet-mixed mortar enters the storage tank body 101 through the injection pipe 104. The stirring motor 201 is started to make the stirring blades 204 continuously stir. The conveying motor 305 is started so that the wet-mixed mortar inside the storage tank body 101 moves towards the discharge port 306 under the drive of the rotating shaft 302 and the spiral blades 303 until it is discharged through the discharge port 306.

[0044] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
