Description

Technical Field

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

[0002] Concrete, also known as "concrete", is a general term for engineering composite materials that are made of cementitious materials that bind aggregates into a whole. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] When processing concrete, a variety of raw materials are mixed together. However, before mixing, the raw materials need to be sampled to detect whether the raw materials are qualified, and a sampling device is needed. However, when sampling concrete, some existing sampling devices usually directly insert the sampler into the raw material, and then allow the raw material to directly enter the sampler through the feed port and then be pulled out. Since the feed port is not sealed, raw materials in other areas enter the sampler, which affects subsequent detection.

[0004] In view of the above problems, a concrete raw material sampling device is proposed. Utility Model Content

Detailed implementation mode

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0023] To further understand the content of the present invention, the present invention will be described in detail in conjunction with the accompanying drawings.

[0024] Please refer to Figures 1-4 , the present invention provides a technical solution: a concrete raw material sampling device, including a connecting rod 4. One end of the connecting rod 4 is fixedly installed with a sampler 1. A material port 2 is opened on the surface of the sampler 1. A rotating shaft 5 is rotatably connected inside the connecting rod 4. A sliding inner rod 9 is slidably connected inside the rotating shaft 5. One end of the sliding inner rod 9 penetrates through the rotating shaft 5 and extends into the sampler 1. A connecting plate 15 is fixedly installed at the end of the sliding inner rod 9 extending into the sampler 1. A sealing cover 3 is fixedly installed at the bottom of the connecting plate 15. The sealing cover 3 coincides with the material port 2.

[0025] Insert the sampler 1 into the concrete raw material, and then push the sliding inner rod 9 to move, so that the sliding inner rod 9 slides inside the rotating shaft 5, so that the connecting plate 15 and the sealing cover 3 move, so that the sealing cover 3 no longer seals the material port 2, so that the external material enters the sampler 1. When the sampling is completed, reset the sliding inner rod 9, so that the sealing cover 3 seals the material port 2, which is convenient for sampling at a specific position, so as to prevent external interference and reduce the entry of concrete raw material in non-specific areas into the sampler 1, thereby ensuring the accuracy of detection.

[0026] A first disc 7 is fixedly sleeved on the rotating shaft 5. A torsion spring 6 is movably sleeved on the surface of the rotating shaft 5. One end of the torsion spring 6 close to the connecting rod 4 is fixedly connected to the connecting rod 4. One end of the torsion spring 6 far from the connecting rod 4 is fixedly connected to the first disc 7. A second disc 13 is fixedly installed at the end of the sliding inner rod 9 far from the connecting rod 4. A elastic spring 8 is movably sleeved on the sliding inner rod 9. Both ends of the elastic spring 8 are fixedly connected to the opposite sides of the second disc 13 and the first disc 7 respectively.

[0027] When pressing the second disc 13, the elastic spring 8 will be compressed, and then it can be reset through the elastic spring 8 to achieve sealing.

[0028] A rotating rod 10 is rotatably connected to the first disc 7. The rotating rod 10 is movably connected inside the second disc 13. A groove 12 is provided on the second disc 13, and a convex block 11 is fixedly installed on the rotating rod 10. The convex block 11 fits with the groove 12.

[0029] When pressing the second disc 13, the second disc 13 will slide on the surface of the groove 12, and then the convex block 11 will slide inside the groove 12. After the convex block 11 slides past the groove 12, rotate the convex block 11 so that the convex block 11 and the groove 12 are not in the same straight line, thereby blocking the second disc 13, and then facilitating the opening of the material port 2.

[0030] A vibration box 14 is fixedly installed inside the sampler 1. The rotating shaft 5 rotatably penetrates the vibration box 14 and extends to the other side of the vibration box 14. A spring 16 is fixedly installed on the surface of the rotating shaft 5 inside the vibration box 14. One end of the spring 16 is fixedly installed with a knocking ball 17, and a fixed convex block 18 is fixedly installed inside the vibration box 14.

[0031] Rotate the first disc 7 to drive the rotating shaft 5 to rotate by the first disc 7, thereby deforming the torsion spring 6. Then when the rotating shaft 5 rotates, the spring 16 and the knocking ball 17 will rotate following the rotating shaft 5, so that the knocking ball 17 knocks on the fixed convex block 18, thereby making the vibration box 14 and the sampler 1 vibrate, thereby facilitating the raw material to enter the inside of the sampler 1, and then facilitating sampling and improving the smoothness of the raw material entering the inside of the sampler 1.

[0032] Working principle:

[0033] Insert the sampler 1 into the concrete raw material, then push the sliding inner rod 9 to move, so that the sliding inner rod 9 slides inside the rotating shaft 5, then the connecting plate 15 and the sealing cover 3 move, so that the sealing cover 3 no longer seals the material port 2, and then the external material enters the inside of the sampler 1. When the sampling is completed, reset the sliding inner rod 9, so that the sealing cover 3 seals the material port 2, which is convenient for sampling at a specific position.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
