Description

Technical Field

[0001] The utility model belongs to the technical field of concrete detection, and particularly relates to a device for sampling concrete test blocks. Background Art

[0002] After the concrete is prepared, it needs to be sampled and detected to understand whether it meets the construction requirements.

[0003] At present, the common traditional concrete sampling method is to shovel out the concrete sample with a shovel, and then transfer the shoveled concrete sample to fill into the test block mold. The operation is simple and fast. However, during the process of transferring the concrete after sampling with the shovel, the concrete is very likely to fall from the shovel to the ground. Moreover, during the process of filling the concrete sample into the test block mold with the shovel, if the worker cannot hold the shovel steadily, part of the concrete will slide down along the outer wall of the test block mold to the ground, resulting in relatively serious waste of concrete. And once the concrete scattered on the ground solidifies, it is difficult to handle, and it will also damage the flatness of the ground.

[0004] Therefore, it is necessary to provide an improved technical solution for the above deficiencies in the prior art. Summary of the Utility Model

[0029] The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0030] Embodiment. This embodiment aims to provide a concrete test block sampling device, and its main function is reflected in that it can effectively reduce the waste of concrete during the transfer process of the concrete sample and during the process of injecting the concrete sample into the test block mold.

[0031] Refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, including: a material taking mechanism and an umbrella cover 3. The material taking mechanism is composed of a pair of cross-hinged material taking spoons. The two cross-hinged material taking spoons are in an X shape. Specifically, the material taking spoon includes: a spoon body 1 and a spoon rod 2. The outer shape of the spoon body 1 is hemispherical. The spoon body 1 is fixed at the head, i.e., the lower end, of the spoon rod 2. A through hole 5 is provided in the middle of one of the spoon rods 2 for the other spoon rod 2 to pass through, so that the ends of the two spoon rods 2 are aligned. The middle overlapping parts of the two spoon rods 2 are connected in series by a pin shaft 6, and baffles 7 are fixed at both ends of the pin shaft 6 to prevent the two spoon rods 2 from separating from each other. Thus, the two material taking spoons can be hinged together. Among them, handles 11 are horizontally fixed at the tails, i.e., the upper ends, of the two spoon rods 2, so that the staff can control the rotation of the two spoon rods 2 through the handles 11 to make their tails and heads contact simultaneously, and further make the hemispherical spoon bodies 1 at the heads of the two spoon rods 2 stick together to form a sealed spherical space. Further, in order to improve the sealing performance at the joint of the two spoon bodies 1, rubber rings can be fixed along the circumference of the spoon mouths at the joints of the two spoon bodies 1 respectively.

[0032] Refer to Figure 2 and Figure 4 , the umbrella cover 3 is sleeved outside the two spoon rods 2. The narrow end, i.e., the upper end, of the umbrella cover 3 faces the tails of the spoon rods 2, and the thick end, i.e., the lower end, of the umbrella cover 3 faces the heads of the spoon rods 2. A pair of guide rods 8 protrude upward at the narrow end of the umbrella cover 3 corresponding to the two baffles 7 respectively. Handles 11 are horizontally fixed at the upper ends of the mutually remote sides of the two guide rods 8. Guide grooves 9 are provided in the middle of the mutually corresponding sides of the two guide rods 8 along their lengths. A support rod 10 is horizontally arranged between the guide groove 9 and the corresponding baffle 7. One end of the support rod 10 is butt-jointed and fixed to the middle of the corresponding baffle 7, and the other end of the support rod 10 extends into the corresponding guide groove 9. The support rod 10 can be a rectangular rod, so that the guide plate can only displace along its own length direction, and further make the umbrella cover 3 move up and down. By moving the umbrella cover 3 upward, the two hemispherical spoon bodies 1 can be completely exposed, and by moving the umbrella cover 3 downward, the two hemispherical spoon bodies 1 can be completely covered.

[0033] Refer to Figure 4 , a diversion nozzle 4 is provided on the cover wall of the umbrella cover 3 corresponding to the joint of the two spoon bodies 1. The diversion nozzle 4 is formed by concave-convex of the cover wall of the umbrella cover 3. The diversion nozzle 4 is for facilitating the diversion of the concrete sample. By corresponding the diversion nozzle 4 with the joint of the two spoon bodies 1, the concrete sample flowing out of the sealed spherical space can quickly fall into the diversion nozzle 4, so as to accelerate the speed of filling the concrete sample into the test block mold; a hand-held rod 12 corresponding to the diversion nozzle 4 is provided outside the cover wall of the umbrella cover 3. Through the hand-held rod 12, it is convenient for the staff to change the direction of the umbrella cover 3, that is, the umbrella cover 3 is vertical during the sampling and sample transfer processes. When filling the concrete sample into the test block mold, it is necessary to change the vertical umbrella cover 3 to horizontal through the hand-held rod 12. Correspondingly, the two material taking spoons also become horizontal.

[0034] In actual use, first lift the umbrella cover 3 upwards to completely expose the two spoon bodies 1. Place the two spoon bodies 1 into the mixed concrete. Whether to completely immerse or semi-immerse the spoon bodies 1 depends on the actual amount of sample to be taken. Open the tails of the two spoon rods 2, and the two spoon bodies 1 will also open correspondingly. The concrete enters the cavity of the spoon bodies 1. Then close the tails of the two spoon rods 2, and the two spoon bodies 1 will also closely fit together. Lift the two spoon bodies 1 upwards from the concrete and pause for a moment. During this period, the concrete adhering to the outer side of the spoon bodies 1 will flow down along its arc surface back into the concrete below. Next, transfer the concrete sample. After reaching the designated position, place the umbrella cover 3 horizontally so that the diversion nozzle 4 corresponds to the cavity opening of the test block mold. At this time, slowly open the tails of the two spoon rods 2, and the two spoon bodies 1 will also open correspondingly. The concrete sample flows out from the cavity of the spoon bodies 1. Since the inner wall of the umbrella cover 3 is inclined and has a curvature, the flowing concrete sample will automatically slide down along the inner wall of the umbrella cover 3 and gather at the diversion nozzle 4. The concrete sample is diverted through the diversion nozzle 4 so that it accurately falls into the mold cavity of the test block mold.

[0035] The sampling device provided in this embodiment can greatly reduce the scattering of concrete during the process of transferring the concrete sample, and can prevent the phenomenon that the concrete slides down along the outer wall of the test block mold to the ground during the process of filling the concrete sample into the test block mold, thereby avoiding the problem of serious waste of concrete in the concrete test block sampling work, and at the same time can effectively protect the flatness of the ground.

[0036] It can be understood that the above description is only exemplary, and the embodiments of the present application do not limit this.

[0037] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are within the scope of protection of the pending claims of the present invention.
