The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model provides a concrete retarder detection sampling device, such as Figure 1-3 As shown, the concrete retarder detection sampling device includes: a sampling tube 1; an auger 2, which is rotatably mounted on the sampling tube 1; a rotating motor 3, which is fixedly mounted on the sampling tube 1, and the output shaft of the rotating motor 3 is fixedly connected to the auger 2; a discharge port 4, which is opened on the sampling tube 1; a feed port 5, which has multiple feed ports 5, and multiple feed ports 5 are all opened on the sampling tube 1; a mounting cover 6, which is fixedly mounted on the sampling tube 1 and arranged corresponding to the feed port 5; a guide bucket 7, which has multiple guide buckets 7 and is arranged corresponding to the feed port 5, and multiple guide buckets 7 are respectively fixedly mounted on the sampling tube 1 and located in the mounting cover 6; an adjusting guide mechanism, which has multiple adjusting guide mechanisms for controlling the selection of sampling points, and multiple adjusting guide mechanisms are arranged on the mounting cover 6 and corresponding to the feed port 5.

[0021] In this embodiment, the design of the sampling tube 1 enables the concrete sample to enter and be stored in the tube smoothly, which provides convenience for subsequent testing. The auger 2 is rotatably installed on the sampling tube 1 to help the concrete sample move smoothly in the sampling tube 1. Through the rotation of the auger, the concrete sample can be effectively discharged from the discharge port 4, which improves the sampling efficiency. The rotating motor 3 ensures that the auger can rotate stably and continuously. The discharge port 4 and the feed port 5 are two important openings on the sampling tube. The discharge port 4 is used to discharge the concrete sample, which is convenient for subsequent testing and analysis. The feed port 5 is responsible for introducing the concrete into the sampling tube 1. The design of multiple feed ports 5 enables the device to sample from multiple sampling points, which improves the representativeness of the sampling. The setting of the mounting cover 6 and the guide bucket 7 further improves the accuracy of sampling. The mounting cover 6 is fixedly installed on the sampling tube and is arranged corresponding to the feed port 5, which plays a role in protecting the feed port 5 and preventing concrete from splashing out. The guide bucket 7 is responsible for guiding the concrete to the corresponding feed port 5 to ensure that the sample can accurately enter the sampling tube. By adjusting the guide mechanism, the feed ports 5 at different positions can be conveniently selected for sampling, thereby sampling and testing concrete in different areas. This design not only improves the flexibility of sampling, but also reduces the workload of the staff.

[0022] In a further preferred embodiment of the utility model, the adjusting guide mechanism includes a through opening 8, a sealing plate 9, a slide groove 10 and a driving mechanism, the through opening 8 is opened on the mounting cover 6 and is arranged corresponding to the guide bucket 7, the sealing plate 9 is slidably arranged on the through opening 8 and conflicts with the guide bucket 7, the slide groove 10 is opened on the mounting cover 6, the slide groove 10 is slidably connected to the sealing plate 9, and the driving mechanism is arranged in the mounting cover 6 to control the opening and closing of the sealing plate 9.

[0023] In this embodiment, the sealing plate 9 can slide on the through opening 8, so as to achieve the shielding or opening of the guide bucket 7. When the sealing plate 9 blocks the guide bucket 7, it can prevent concrete from entering the sampling tube 1 from the feed port 5; when the sealing plate 9 opens the guide bucket 7, concrete is allowed to enter. The sampling point can be conveniently selected, which improves the flexibility of sampling. The sliding setting of the sealing plate 9 enables it to move easily on the through opening 8, so as to achieve the rapid shielding or opening of the guide bucket 7, and improve the efficiency of sampling. The slide 10 provides a stable sliding track for the sealing plate 9, ensuring the stability and accuracy of the sealing plate 9 during the movement, avoiding the displacement or shaking of the sealing plate 9 during the movement, and further improving the accuracy of sampling. By controlling the driving mechanism, the opening and closing state of the sealing plate 9 can be conveniently controlled. This design makes the operation more convenient and reduces the workload of the staff.

[0024] In a further preferred embodiment of the utility model, the driving mechanism includes a connecting block 11, a fixed block 12, a screw 13, a first bevel gear 14, an adjusting motor 15 and a second bevel gear 16, the connecting block 11 is fixedly mounted on the sealing plate 9, the fixed block 12 is fixedly mounted in the mounting cover 6, the screw 13 is rotatably mounted on the fixed block 12 and is rotatably connected to the side wall of the guide bucket 7, the screw 13 is threadedly connected to the connecting block 11, the first bevel gear 14 is fixedly mounted on the screw 13, the adjusting motor 15 is fixedly mounted on the mounting cover 6, and the second bevel gear 16 is fixedly mounted on the output shaft of the adjusting motor 15 and meshes with the first bevel gear 14.

[0025] In this embodiment, the driving mechanism can effectively control the movement of the sealing plate 9 through the connecting block 11. The fixed installation of the connecting block 11 ensures its stability during the movement, thereby ensuring that the sealing plate 9 can be accurately moved into place. The fixing block 12 provides a stable installation base for the screw 13, and the screw 13 can stably rotate on the fixing block 12, and at the same time, by connecting with the side wall of the guide bucket 7, the sealing plate 9 is driven. When the screw 13 rotates, due to the effect of the thread, the connecting block 11 will move along the axial direction of the screw 13. When the adjusting motor 15 is started, its output shaft drives the second bevel gear 16 to rotate, and then drives the first bevel gear 14 and the screw 13 to rotate. By adjusting the forward and reverse rotation of the motor 15, the opening and closing direction of the sealing plate 9 can be easily controlled, thereby realizing the selection of different feed ports 5. This automated control method not only improves the sampling efficiency, but also reduces the labor intensity of the staff.

[0026] In a further preferred embodiment of the present invention, a discharge hopper 17 is fixedly installed outside the sampling tube 1 , and the discharge hopper 17 is arranged corresponding to the discharge port 4 .

[0027] In this embodiment, the design of the discharge hopper 17 enables the concrete sample to flow more smoothly into the collection container or other subsequent processing equipment when discharged. Since the discharge hopper 17 has a certain inclination angle and opening design, it can effectively guide the concrete sample to flow out from the discharge port 4 and prevent the sample from splashing or clogging during the outflow process. The corresponding setting of the discharge hopper 17 and the discharge port 4 ensures that the sample can flow into the hopper accurately. This design avoids the deviation or omission of the sample during the outflow process, and improves the accuracy and reliability of sampling.

[0028] In a further preferred embodiment of the utility model, a protective cover 18 is fixedly installed on the sampling tube 1, and the protective cover 18 is fixedly connected to the rotating motor 3. A stabilizing block 19 is fixedly installed on the sampling tube 1, and the stabilizing block 19 is fixedly connected to the protective cover 18. A handle 20 is fixedly installed on the stabilizing block 19, and an anti-slip pad is fixedly installed on the handle 20.

[0029] In this embodiment, the fixed installation of the protective cover 18 not only protects the rotating motor 3 from direct impact and damage by external objects, and prolongs the service life of the motor, but also prevents concrete fragments or particles that may be generated during the sampling process from splashing onto the motor, thereby ensuring the normal operation of the motor. The fixed connection between the protective cover 18 and the rotating motor 3 also enhances the stability of the entire device, and reduces the risk of loosening or falling off of components due to vibration or external force. The introduction of the stabilizing block 19 further enhances the stability of the sampling device. The stabilizing block 19 is fixedly mounted on the sampling tube 1 and connected to the protective cover 18 to form a stable support structure. The setting of the handle 20 greatly facilitates the operation and control of the sampling device by the staff. The staff can conveniently move and adjust the position and angle of the sampling device by holding the handle 20, thereby realizing flexible selection of the sampling point. The addition of the anti-slip pad enhances the friction of the handle 20, so that the staff can hold the handle more firmly during operation, thereby preventing operational errors or safety accidents caused by hand slippage.

[0030] In a further preferred embodiment of the present invention, a conical block 21 is fixedly mounted on the top end of the sampling tube 1 , and the conical block 21 is fixedly connected to the mounting cover 6 .

[0031] In this embodiment, the design of the conical block 21 can guide and concentrate the flow of concrete. During the sampling process, the concrete sample enters through the sampling tube 1 and flows more concentratedly to the guide bucket 7 in the mounting cover 6 under the guidance of the conical block 21. This design helps to ensure that the concrete sample can enter the sampling device accurately and efficiently, thereby improving the accuracy and efficiency of sampling. The fixed connection between the conical block 21 and the mounting cover 6 further enhances the structural stability of the entire sampling device. This connection method ensures a firm connection between the sampling tube 1, the conical block 21 and the mounting cover 6, reduces the risk of loosening or falling off of components due to vibration or external force, and also enhances the overall rigidity and stability of the sampling device, making the sampling process smoother and more reliable.

[0032] In a further preferred embodiment of the utility model, two protrusions are arranged in each of the plurality of slide grooves 10, and grooves are opened on each of the plurality of sealing plates 9 and are arranged corresponding to the protrusions.

[0033] In this embodiment, the matching design of the protrusion and the groove makes the sliding of the sealing plate 9 in the slide groove 10 more stable and accurate. The protrusion can be embedded in the groove of the sealing plate 9 to form a locking mechanism to prevent the sealing plate 9 from shifting or shaking during the sliding process. This design ensures that the sealing plate 9 can be accurately moved to the desired position, thereby effectively blocking or opening the guide bucket 7. The design of the protrusion and the groove also enhances the connection strength between the sealing plate 9 and the mounting cover 6. Through the close fit of the protrusion and the groove, the connection between the sealing plate 9 and the mounting cover 6 is more secure, reducing the risk of loosening or falling off of components due to external forces. This design improves the structural stability of the entire device and ensures its reliability under long-term use or in harsh environments.

[0034] In summary, compared with related technologies, this device achieves a more efficient, accurate and safe sampling process as a whole. Taking the safety of operators into consideration, sampling can be achieved without the operator approaching the sample pipeline, reducing potential safety risks. The design of the protective cover also effectively protects the rotating motor from the impact of external objects and enhances the durability of the device. The introduction of the discharge hopper ensures that the sample can flow smoothly into the collection container, while the stabilizer block enhances the stability of the device and reduces shaking during the sampling process. These designs together improve the stability and convenience of the sampling work. The design of the bumps and grooves between the slide and the sealing plate not only improves the stability of the sliding of the sealing plate, but also simplifies the installation and disassembly process and reduces maintenance costs.
