Description

Technical Field

[0001] The utility model relates to the technical field of concrete quality inspection, in particular to a concrete sampling device. Background Art

[0002] Concrete is one of the most important civil engineering materials in contemporary times. It is an artificial stone made of cementitious materials, granular aggregates or aggregates, water, and admixtures and additives added in a certain proportion, and then mixed, compacted, formed, and cured and hardened. Concrete has the characteristics of abundant raw materials, low price, simple production process, high compressive strength and good durability.

[0003] In order to ensure that concrete does not have large quantities of incorrect raw material ratios and quality deterioration, the produced concrete needs to be sampled and inspected regularly. The more common sampling method is to insert a long cylindrical sampler into a container filled with concrete to sample the upper, middle and lower parts. When the above method is implemented, due to the high viscosity of concrete, the staff needs to spend a lot of force to pull the long cylindrical sampler out of the container filled with concrete, and taking the sampled concrete out of the long cylindrical sampler also requires cumbersome operating steps, which reflects the difficulty of concrete sampling.

[0025] Working principle of this utility model:

[0026] When concrete sampling is required, the sampling bag with the hand ring is first hung on the outside of the inverted frame 221 through the two bag hanging parts 222, and then a force is applied to the force rod 217 in the direction of the rotating block 216. The force rod 217 will drive the extrusion rod 2112 to move and generate an extrusion force on the top of the T-shaped limit block 2110. During this process, the T-shaped limit block 2110 is forced to move into the T-shaped hole. When the hemispherical top of the T-shaped limit block 2110 moves to the gap between the rotating block 216 and the mounting plate 218, the T-shaped limit block 2110 cannot limit The rotating block 216 rotates, and then a clockwise steering force is applied to the force-applying rod 217. The force-applying rod 217 drives the rotating block 216, the rotating rod 213 and the adjusting plate 214 to rotate clockwise, and rotates the adjusting plate 214 to a position where the concrete can be drained. The concrete is then drained into the sampling bag by the adjusting plate 214, the arc-shaped drainage piece 215, the extension plate 212 and the U-shaped diverter plate 211 and collected. When the sampling volume is sufficient, the force-applying rod 217 is used to drive the adjusting plate 214 to reset. The required force is small, the operation is simplified, and the difficulty of concrete sampling is reduced.
