Description

Technical Field

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

[0002] Concrete is a general term for engineering composite materials that are formed by cementitious materials binding aggregates into a whole. The term concrete generally refers to cement as the binder, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a certain proportion, and then mixed to form cement concrete, also known as ordinary concrete. It is widely used in civil engineering.

[0003] After concrete processing is completed, its performance needs to be tested to determine whether the concrete meets the construction requirements. The existing concrete test block construction method is to take out the concrete with a sampling device and then fill it into the test block mold. When sampling concrete, although there is no rigid requirement that the weight of each sample be consistent, there must be certain requirements for the total amount taken by each truck. The existing sampling device usually does not have the function of observing the weight of the sample. Therefore, in response to the above situation, a concrete sampling device is proposed. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a concrete sampling device to solve the existing problems.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical solution: a concrete sampling device, whose structure includes a device body, the device body includes a shovel and a connecting block, the shovel is connected to the connecting block, the connecting block is also connected to a telescopic rod, the telescopic rod is connected to a connecting rod, the connecting rod is connected to a handle, and the connecting rod and the handle are threadedly connected.

[0006] Furthermore, the scoop consists of a surface layer, a weighing layer and a bottom layer. The weighing layer is a pressure sensor. The surface layer is made of ABS plastic, and the bottom layer is made of a composite material.

[0007] Furthermore, the shovel spoon is in an arc shape and a wear-resistant strip is provided at the end of the shovel spoon. The wear-resistant strip is in a triangular prism shape and is made of a material with wear-resistant properties.

[0008] Furthermore, the interior of the connecting rod is a cavity and a counterweight ball is provided inside the connecting rod.

[0009] Furthermore, a digital display screen is provided on the telescopic rod, which is electrically connected to the weighing layer and a battery is provided inside the connecting block for powering the weighing layer and the digital display screen. The battery setting is conventional technology and is therefore not reflected in the accompanying drawings.

[0010] The beneficial effects of the utility model are:

[0011] A weighing layer is provided to weigh the weight of each sample, so that the weight of each truck of concrete after multiple samplings can be clearly known;

[0012] The top layer and bottom layer are made of wear-resistant and lightweight materials, which not only protect the shovel but also reduce the overall weight of the shovel.

[0013] The wear-resistant strip not only improves the wear resistance of the shovel, but also makes it easier to insert it into the concrete during sampling due to its triangular prism shape.

[0014] There is also a counterweight ball. When the counterweight ball is sampling, the lower fork will be downward due to gravity, making it easier to insert it into the concrete. When the sampled concrete is poured into the test block mold, the counterweight ball will also be pulled back due to inertia, making it easier to shovel the concrete.

[0015] The connecting rod and the handle are threadedly connected, and you can choose whether to use the counterweight ball or replace it with a heavier counterweight ball according to the situation. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] See also Figure 1-Figure 5 The utility model provides a technical solution for a concrete sampling device: its structure includes a device body 1, the device body 1 includes a shovel 2 and a connecting block 3, the shovel 2 is connected to the connecting block 3, the connecting block 3 is further connected to a telescopic rod 4, the telescopic rod 4 is connected to a connecting rod 5, the connecting rod 5 is connected to a handle 6, and the connecting rod 5 and the handle 6 are threadedly connected;

[0025] The shovel 2 is composed of a surface layer 201, a weighing layer 202 and a bottom layer 203. The weighing layer 202 is a pressure sensor used to weigh the concrete on the surface layer 201.

[0026] The shovel 2 is arc-shaped and a wear-resistant strip 204 is provided at the end of the shovel 2. The wear-resistant strip 204 is in the shape of a triangular prism. The wear-resistant strip is not only used to improve the wear resistance of the shovel, but also makes it easier to insert the shovel into the concrete when taking samples.

[0027] The interior of the connecting rod 5 is hollow and is provided with a weighted ball 501. When the weighted ball is used for sampling, the lower fork will be pulled downward by gravity, making it easier to insert the sample into the concrete. When the sampled concrete is poured into the test block mold, the weighted ball will also be pulled backward by inertia, making it easier to shovel the concrete.

[0028] The telescopic rod 4 is also provided with a digital display screen 7, which is electrically connected to the weighing layer 202 and a battery is provided inside the connecting block 3 for powering the weighing layer 202 and the digital display screen 7. The digital display screen is used to display the weighing value of the weighing layer.

[0029] For example, when sampling, the device body is inserted into the concrete to be sampled, so that the shovel 2 scoops up the sampled concrete. At this time, the weighing layer 202 weighs the concrete on the shovel 2 and displays it on the digital display 7;

[0030] When sampling concrete, the shovel 2 will be inserted downward, which will cause the counterweight ball 501 to exert a force in the downward direction, making it easier for the shovel 2 to be inserted into the concrete. When the shovel 2 scoops up the sampled concrete and pours it into the mold, the counterweight ball will also exert a force backward due to inertia, making it easier to scoop up the concrete.

[0031] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
