Description

Technical Field

[0001] This utility model relates to the field of concrete sampling, specifically a concrete sampling device. Background Technology

[0002] Concrete is a general term for engineering composite materials in which aggregates are bound together by cementing materials. The term concrete usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as cementing material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering.

[0003] In the prior art, when sampling and inspecting concrete, it is necessary to manually use a box or similar object to take the mixed concrete, then transfer the box after taking the concrete, and manually turn the box with the concrete on it to pour the concrete onto a dry, waterless iron plate. Based on this, in order to facilitate manual pouring and improve the convenience of operation, this utility model proposes a concrete sampling device. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-3 In this embodiment of the utility model, a concrete sampling device includes a fixed rod 1, a material box 2 fixed to the inner side of the end of the fixed rod 1, and a driving limiting mechanism 3 set on the fixed rod 1 and the material box 2.

[0028] The limiting mechanism 3 includes a support unit and a transmission unit;

[0029] The support unit is used to support the material inside the hopper 2;

[0030] The transmission unit is used to limit the movement of the support unit;

[0031] The support unit includes a fixed rod 304, a flap 305, and a support block 306;

[0032] The fixing rod 304 is fixed to the bottom of the material box 2 by the connecting rod. The fixing rod 304 is used to provide support for the rotation of the flip plate 305.

[0033] The flap 305 is rotatably sleeved on the outer wall of the fixed rod 304, and the flap 305 is used to provide support for the material inside the material box 2;

[0034] The support block 306 is fixed to the bottom of the flap 305, and the support block 306 is used to ensure that there is a certain space between the flap 305 and the ground;

[0035] The transmission unit includes a push rod 301, a U-shaped stop block 302, and a slider 303;

[0036] The push rod 301 is axially slidably mounted on the bottom of the fixed rod 1 and extends to the outside of the material box 2. The push rod 301 is used to synchronously drive the U-shaped abutment block 302 to move.

[0037] The U-shaped stop 302 is fixed to the outer wall of the push rod 301 and extends to the bottom of the flap 305. The U-shaped stop 302 is used to limit the rotation of the flap 305.

[0038] The slider 303 is fixed to the top of the push rod 301 and extends into the interior of the fixed rod 1. The slider 303 is used to guide the axial movement of the push rod 301.

[0039] In this embodiment: When it is necessary to take a sample of concrete, the hopper 2 is placed behind the concrete discharge opening, and then the discharge opening is opened to allow the concrete to fall into the hopper 2. Its two flap plates 305 block the bottom of the hopper 2 to support and hold the concrete. Then, the worker moves the sampled hopper 2 to an anhydrous and dry iron plate. By applying an outward pulling force to the push rod 301, the push rod 301 drives the U-shaped abutting block 302 to move synchronously, so that the U-shaped abutting block 302 no longer abuts under the flap plate 305. Then, the flap plate 305 rotates around the axis of the fixed rod 304. The rotating flap plate 305 no longer supports the concrete material on the inner wall of the hopper 2, and the concrete material falls from the hopper 2 to the iron plate under the action of gravity, completing the concrete sampling operation. There is no need to manually turn the hopper 2 as a whole, reducing the manual labor intensity and further improving the work efficiency.

[0040] Please refer particularly to Figures 1-3 , the outer wall of the slider 303 is integrally in a "convex" shape. A chute for the axial movement of the slider 303 is formed on the inner side of the fixed rod 1. The outer wall of the U-shaped abutting block 302 is in a U shape. The two ends of the U-shaped abutting block 302 respectively abut under one flap plate 305. The number of flap plates 305 is two, and the two flap plates 305 are symmetrically distributed on the outer wall of the fixed rod 304.

[0041] In this embodiment: With this structure, after the concrete material in the hopper 2 has fallen, the hopper 2, the flap plate 305, and the fixed rod 304 can be washed by water flow. Then, the flap plate 305 is made to contact the ground again so that the flap plate 305 is combined again. After combination, the flap plate 305 still has a certain space from the ground through the support block 306. Then, a pushing force is applied to the push rod 301 again to drive the U-shaped abutting block 302 to move under the flap plate 305 again to support the flap plate 305.

[0042] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
