Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling device technology, and more specifically, to a sampling device for engineering testing. Background Technology
[0002] Building materials refer to all kinds of materials used in civil engineering and construction engineering. They are the material basis for building structures. Building materials need to be tested before use to ensure the safety and performance of the building. Therefore, sampling devices are needed to drill and take samples of building materials to facilitate the testing work.
[0003] Based on the above, the inventors have discovered that existing sampling devices use a hand drill to drive a drill barrel to drill holes and collect material samples. However, the samples are collected inside the drill barrel, which is inconvenient to retrieve. In addition, a large amount of debris and dust are generated during the drilling and sampling process, which pollutes the sampling environment. Therefore, in view of this, the inventors have studied and improved the existing structure to provide a sampling device for engineering testing, in order to achieve a more practical purpose. Utility Model Content
[0004] 1. Technical problems to be solved
[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a sampling device for engineering testing. This solution is equipped with a dust prevention component, which can be fixed on the outside of the sampling position to centrally process the debris and dust generated during drilling sampling, purifying the sampling environment. In addition, a discharge component is provided to allow the core sample to quickly detach from the sampling device, facilitating the testing work and improving the efficiency of drilling sampling.
[0006] 2. Technical Solution
[0007] To solve the above problems, the present invention adopts the following technical solution.
[0008] A sampling device for engineering testing includes an electric drill. Support rods are fixedly connected to both sides of the front end of the electric drill, and a rotating rod is fixedly connected to the output end of the electric drill. A drill cylinder is fixedly connected to one end of the rotating rod, and a protective cover is provided on the outside of the drill cylinder. A discharge mechanism is provided inside the rotating rod. A guide rod is fixedly connected to one end of the support rod, and a limit block is fixedly connected to one end of the guide rod. A first return spring is fixedly connected to the outside of the guide rod.
[0009] The discharge mechanism includes a sliding sleeve, a connecting rod is fixedly connected to the center of the inner side of the sliding sleeve, a push plate is fixedly connected to one end of the connecting rod, and a set of second return springs is fixedly connected at the connection between the connecting rod and the sliding sleeve.
[0010] Furthermore, a suction cup is fixedly connected to the front end of the protective cover, and the front end of the suction cup is flush with the front end of the drill barrel.
[0011] Furthermore, the limiting block is located on the inner side of the protective cover, and the limiting block is slidably connected to the protective cover.
[0012] Furthermore, the two ends of the first reset spring are fixedly connected to the support rod and the rear end of the protective cover, respectively.
[0013] Furthermore, the sliding sleeve is located outside the rotating rod, the connecting rod is located inside the rotating rod, and the connection between the sliding sleeve and the connecting rod is slidably connected to the rotating rod.
[0014] Furthermore, the pusher plate is located inside the drill barrel, and the outer side of the pusher plate is in contact with the inner surface of the drill barrel.
[0015] Furthermore, one end of the second return spring and sliding sleeve is fixedly connected to the inner surface of the rotating rod.
[0016] 3. Beneficial effects
[0017] Compared with existing technologies, the advantages of this utility model are:
[0018] (1) This solution uses a suction cup to adhere to the sample surface. Then, as the drill barrel moves, the limiting block slides inside the protective cover, fixing the protective cover to the outside of the sampling position. This concentrates the dust and debris generated by the drilling. Compared with the prior art, the dustproof component can be fixed to the outside of the sampling position to concentrate the dust and debris generated by the drilling and purify the sampling environment.
[0019] (2) By setting up a discharge mechanism, the sliding sleeve moves to the front end, driving the connecting rod to move synchronously. The connecting rod drives the push plate to move inside the drill cylinder, so that the core sample falls from the front end of the drill cylinder and the sampling work is completed. Compared with the existing technology, the discharge component is set up so that the core sample can quickly fall out from the inside of the sampling device, which facilitates the detection work and improves the efficiency of drilling and sampling.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0026] Example:
[0027] Please see Figure 1-4 A sampling device for engineering testing includes an electric drill 1. Support rods 2 are fixedly connected to both sides of the front end of the electric drill 1, and a rotating rod 3 is fixedly connected to the output end of the electric drill 1. A drill cylinder 4 is fixedly connected to one end of the rotating rod 3. A protective cover 5 is provided on the outside of the drill cylinder 4. A discharge mechanism 7 is provided inside the rotating rod 3. A guide rod 8 is fixedly connected to one end of the support rod 2. A limit block 9 is fixedly connected to one end of the guide rod 8, and a first reset spring 10 is fixedly connected to the outside of the guide rod 8.
[0028] The discharge mechanism 7 includes a sliding sleeve 11, a connecting rod 12 is fixedly connected to the center of the inner side of the sliding sleeve 11, a push plate 13 is fixedly connected to one end of the connecting rod 12, and a set of second return springs 14 are fixedly connected at the connection between the connecting rod 12 and the sliding sleeve 11. The discharge mechanism 7 is provided for convenient material handling.
[0029] See Figure 1 The front end of the protective cover 5 is fixedly connected to a suction cup 6. The front end of the suction cup 6 is flush with the front end of the drill barrel 4. The sampling personnel hold the electric drill 1 and align the suction cup 6 and the drill barrel 4 with the sampling position so that the suction cup 6 adheres to the sample surface.
[0030] See Figure 3 The limiting block 9 is located on the side of the protective cover 5, close to the inside, and the limiting block 9 is slidably connected to the protective cover 5. When the electric drill 1 is started, the rotating rod 3 and the drill barrel 4 are rotated. At the same time, the electric drill 1 is pressed inward, so that the drill barrel 4 enters the sample and drills a hole for sampling. As the drill barrel 4 moves, the limiting block 9 slides inside the protective cover 5, so that the protective cover 5 is fixed on the outside of the sampling position, and the dust and debris generated by the drilling are collected.
[0031] See Figure 3The two ends of the first return spring 10 are fixedly connected to the support rod 2 and the rear end of the protective cover 5, respectively. As the drill barrel 4 moves, the distance between the protective cover 5 and the support rod 2 decreases, thereby compressing the first return spring 10 and causing it to deform.
[0032] See Figure 2 The sliding sleeve 11 is located outside the rotating rod 3, and the connecting rod 12 is located inside the rotating rod 3. The connection between the sliding sleeve 11 and the connecting rod 12 is slidably connected to the rotating rod 3. Moving the sliding sleeve 11 towards the front end causes the connecting rod 12 to move synchronously.
[0033] See Figure 4 The push plate 13 is located inside the drill barrel 4, and the outer side of the push plate 13 is in contact with the inner surface of the drill barrel 4. The connecting rod 12 drives the push plate 13 to move inside the drill barrel 4, so that the core sample falls from the front end of the drill barrel 4.
[0034] See Figure 4 The second return spring 14 and one end of the sliding sleeve 11 are fixedly connected to the inner surface of the rotating rod 3. Under the action of the second return spring 14, the sliding sleeve 11 and the push plate 13 are driven to facilitate the subsequent sampling work.
[0035] In use: The sampling personnel hold the electric drill 1, align the suction cup 6 and the drill cylinder 4 with the sampling position, and make the suction cup 6 adhere to the sample surface. Then, start the electric drill 1, which drives the rotating rod 3 and the drill cylinder 4 to rotate. At the same time, press the electric drill 1 inward to make the drill cylinder 4 enter the sample to drill and take samples. As the drill cylinder 4 moves, the limiting block 9 slides inside the protective cover 5, which fixes the protective cover 5 outside the sampling position and concentrates the dust and debris generated by drilling. As the drill cylinder 4 moves, the distance between the protective cover 5 and the support rod 2 decreases, thereby compressing the first return spring 10 and causing it to deform until the drilling work is completed. Move the electric drill 1 outward, and then separate the suction cup 6 from the sampling position. Then move the sliding sleeve 11 to the front end, which drives the connecting rod 12 to move synchronously. The connecting rod 12 drives the push plate 13 to move inside the drill cylinder 4, so that the core sample falls from the front end of the drill cylinder 4, completing the sampling work.
