Description

TECHNICAL FIELD

[0001] The application relates to the technical field of concrete, in particular to a concrete sampling device. BACKGROUND

[0002] Concrete is a kind of artificial stone material prepared by mixing cementing material (such as cement), granular aggregate (such as sand and stone), water, and, if necessary, additives and admixtures in a certain proportion, and then uniformly stirring, compacting, curing and hardening.

[0003] For example, the concrete sampling mechanism disclosed in Chinese Utility Model Patent No. CN220084390U inserts a hollow pipe and a hollow sealing frame into the inside of a concrete mixing tank to be sampled, and then moves the hollow pipe vertically at the top by rotating the adjusting bolt, and then drives the push plate to move vertically downward in the hollow pipe, and simultaneously drives the transmission sleeve to move vertically downward outside the hollow pipe under the transmission action of the connecting rod, so that the two sets of hollow sealing frames can be rotated synchronously and oppositely below the hollow pipe under the transmission action of the transmission rod, and the concrete in the tank body is clamped and collected, and then the hollow pipe is pulled outward to move the concrete out of the tank, and the hollow sealing frame is adjusted reversely to rotate outward relative to the hollow pipe to pour out the concrete collected in the hollow sealing frame.
