Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of engineering tests, in particular to a feeding device for cement density testing. Background Art
[0002] Cement is one of the most important building materials. Mortar, concrete, prefabricated components and other products made of cement are strong and durable. They are widely used in civil engineering, water conservancy, national defense and other projects. The quality of products is related to the safety of people's lives and property. Cement density is one of the most important physical indicators for some special projects. It is a prerequisite parameter for the determination of cement specific surface area. The inspection of cement density cannot be ignored.
[0003] The current cement density test method usually adopts the Leclerc flask method (GB / T 208-2014), which generally uses a small spoon to put the cement sample into the Leclerc flask little by little. The process is slow, the cement sample is easy to adhere to the bottle wall during the filling process, and repeated addition is easy to cause experimental errors. Alternatively, the material is quickly added through a funnel, but this method cannot accurately add the right amount of cement sample, which reduces the accuracy of the test. Utility Model Content

[0018] In combination with the first aspect, in one embodiment, a gap is left between the protruding structure of the tamping rod and the inner wall of the second pipe.
[0019] In the embodiment of the present application, a gap is left between the raised structure of the tamping rod and the inner wall of the second pipe, so that the tamping rod can continuously squeeze the cement sample when moving up and down in the second pipe, thereby accelerating the dripping of the cement sample.
[0020] In combination with the first aspect, in one embodiment, the length of the tamping rod can at least allow the tamping rod to extend into the bottom end of the second pipe.

[0039] The embodiment of the present application provides a feeding device for cement density testing, which can solve the problems of slow feeding time and inaccurate measurement accuracy when measuring cement density in the prior art.

[0041] When the second pipe 204 is inserted into the Leclerc flask 3, the conical tube 203 is located at the bottleneck of the Leclerc flask 3. By pouring the cement sample into the first pipe 202, the tamping rod 1 is moved up and down in the second pipe 204, and the multiple adjacent and staggered protrusion structures 102 on the side wall of the tamping rod 1 continuously squeeze the cement sample, which accelerates the smooth dripping of the cement sample, shortens the feeding time, improves the efficiency of the test process, reduces the operating steps of multiple feeding, and improves the measurement accuracy of cement density.
[0042] like Figure 2 As shown, the tamping rod 1 further comprises a cylindrical handle 101, which is connected to the top of the tamping rod 1 to facilitate the tamping rod 1 to move up and down in the second pipe 204.
