[0002] As concrete quality control becomes increasingly stringent, workers frequently need to sample and test concrete during the production process. However, traditional manual sampling typically requires climbing onto the mixer truck and waiting at the discharge port until the truck is full before sampling can be performed. Clearly, existing technologies suffer from problems such as inconvenient sampling, low sampling efficiency, and the sampling only covering the surface layer of concrete at the mixer truck's discharge port, failing to reflect the overall quality of the concrete.

The first end of the sample body is installed on the hopper and is set with a corresponding feeding port. An adjustment component is located within the storage space. A sealing element is connected to the first end of the adjustment component, and the second end of the adjustment component is installed on the inner wall surface of the second end of the sample body. The adjustment component can extend and retract along the length of the sample body to drive the sealing element to block the connection between the sampling port and the discharge port, or to make the sampling port and the discharge port connected.
[0005] In an embodiment of this utility model, the adjustment component includes a linear drive, one end of which is connected to the second end of the sample body, and the other end is connected to a sealing member. The linear drive is used to drive the sealing member to move within the sample body to block or open the sampling port.
[0006] In an embodiment of this utility model, the sample body includes a first sampling part and a second sampling part. The first sampling part is connected to a feeding pipe, and the end of the feeding pipe forms a feeding port. The first end of the first sampling part along the length direction is provided corresponding to the feeding port, and the second end of the first sampling part is connected to the second sampling part.
[0007] In an embodiment of this utility model, the linear drive includes a cylinder and a piston rod slidably inserted into the cylinder. The drive end of the piston rod is connected to a sealing member. When the piston rod retracts to a preset position, the feed end of the feed pipe is located between the outer end face of the sealing member and the first end of the first sampling part.
[0008] In an embodiment of this utility model, the sampling mechanism further includes a power source for providing power to the linear drive component. The linear drive component also includes a delivery pipe. The cylinder includes a rod chamber and a rodless chamber. There are multiple delivery pipes, which are connected to the rod chamber and the rodless chamber in a one-to-one correspondence. All multiple delivery pipes pass through the second sampling section and are connected to the power source.
[0009] In an embodiment of this utility model, the sealing component is made of a wear-resistant material and is adapted to the inner wall surface of the first sampling part. The adjustment component also includes a first locking component, which is multiple in number and detachably connects the sealing component to the first end of the piston rod.
[0010] In an embodiment of this utility model, the adjustment component further includes a second locking fastener, a first flange is provided on the outer wall surface of the material inlet, a second flange is connected to the outer peripheral wall of the first end of the first sampling part, and the number of second locking fasteners is multiple and the first flange and the second flange are detachably connected.
[0011] In an embodiment of this utility model, the feeding pipe is connected to the storage space, the feeding pipe extends along the height direction of the collecting hopper, and the end of the feeding pipe away from the first sampling part is the feeding port.
[0012] In an embodiment of this utility model, a mixing station is also proposed, including the sampling mechanism as described above.

[0014] Through the above technical solutions, the sampling mechanism and mixing station provided by the embodiments of this utility model have the following beneficial effects: The sampling mechanism of this application is located on a hopper.

The sampling body has a discharge port and an internal storage space. A first end of the sampling body is mounted on the hopper and corresponds to the sampling port. The adjusting component is located within the storage space. A sealing element is connected to the first end of the adjusting component, and a second end is mounted on the inner wall of the second end of the sampling body. The adjusting component can extend and retract along the length of the sampling body to drive the sealing element to block the connection between the sampling port and the discharge port, or to connect the sampling port and the discharge port. In this application, by adding a sampling mechanism to the hopper, when sampling is needed, the adjusting component is driven to retract along the length of the sampling body, connecting the sampling port and the discharge port for sampling.

[0017] Explanation of reference numerals in the attached figures Detailed Implementation
[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0019] The sampling mechanism and mixing station according to the present invention are described below with reference to the accompanying drawings.
[0020] like Figure 1 As shown, the sampling mechanism of this application is located on the hopper 40. The bottom of the hopper 40 is provided with a discharge port. A mixer truck 30 is parked below the discharge port to receive materials. A feeding port 401 is opened on the side wall near the bottom of the hopper 40. The sampling mechanism includes a sampling body 1 and an adjusting component 2. The sampling body 1 is provided with a discharge port 22 and has a storage space 11 inside. The first end of the sampling body 1 is installed on the hopper 40 and is set corresponding to the feeding port 401. The adjusting component 2 is located in the storage space 11. The first end of the adjusting component 2 is connected to a sealing member 21, and the second end is installed on the inner wall of the second end of the sampling body 1. The adjusting component 2 can extend and retract along the length direction of the sampling body 1 to drive the sealing member 21 to block the connection between the feeding port 401 and the discharge port 22, or to make the feeding port 401 and the discharge port 22 connected.
[0021] In this application, a sampling mechanism is added to the hopper 40. When sampling is needed, the adjusting component 2 is driven to retract along the length of the sample body 1, connecting the sampling port 401 and the discharge port 22 for sampling. After sampling is completed, the adjusting component 2 can extend along the length of the sample body 1, blocking the sampling port 401 and the discharge port 22, while the sealing component 21 can seal the sampling port 401. This solves the technical problems of inconvenient material sampling, low sampling efficiency, and large sampling limitations in the prior art hopper 40.
[0022] like Figure 2 As shown, in this embodiment, in the field of mixing plant technology, the material that the hopper 40 usually carries is concrete. By setting a sampling mechanism, the concrete in the hopper 40 can be easily obtained. The adjustment component 2 includes a linear drive. One end of the linear drive is connected to the second end of the sampling body 1, and the other end is connected to the sealing component 21. The linear drive is used to drive the sealing component 21 to move within the sampling body 1 to block or open the sampling port 401.
[0023] Specifically, when concrete sampling is required, the linear drive retracts along the length of the sample body 1, connecting the sampling port 401 and the discharge port 22. Concrete in the hopper 40 can enter the storage space 11 through the sampling port 401 and eventually flow out through the discharge port 22. A sampling bucket can be provided to receive the concrete. When concrete sampling is complete, the linear drive extends along the length of the sample body 1, blocking the sampling port 401 and the discharge port 22, thus preventing concrete from flowing out of the discharge port 22, completing the concrete sampling.
[0024] like Figure 3As shown, in this embodiment, the sample body 1 includes a first sampling part 12 and a second sampling part 13. A feeding pipe 14 is connected to the lower part of the first sampling part 12. A feeding port 22 is provided at the bottom end of the feeding pipe 14. Material falling into the storage space from the feeding port 401 can be discharged from the feeding port 22. The first end of the first sampling part 12 along its length is positioned corresponding to the feeding port 401, and the second end of the first sampling part 12 is connected to the second sampling part 13. Specifically, when concrete sampling is required, the linear drive component can retract along the length of the sample body 1 and stop at the end of the first sampling part 12 near the second sampling part 13 to prevent concrete from falling into the position between the second sampling part 13 and the feeding end 141 of the feeding pipe 14. Furthermore, the first sampling part 12 and the second sampling part 13 are detachably connected, making disassembly and assembly convenient.
[0025] like Figure 3 As shown, in this embodiment, the linear drive includes a cylinder 231 and a piston rod 232 slidably inserted into the cylinder 231. The driving end of the piston rod 232 is connected to a sealing member 21. When the piston rod 232 retracts to a preset position 50 (the preset position 50 can be the limit position that the piston rod 232 can reach when retracted), the feed end 141 of the feed pipe 14 is located between the outer end face of the sealing member 21 and the first end of the first sampling part 12, so as to prevent concrete from falling into the position of the sealing member 21 at this time. When the piston rod 232 is fully extended (that is, the piston rod 232 extends to the limit position), the sealing member 21 can completely block the feed port 401, preventing the concrete in the collection hopper 40 from entering the storage space 11. The cylinder 231 is detachably installed on the inner wall surface of the bottom end of the second sampling part 13.
[0026] like Figure 1 and Figure 3 As shown, in this embodiment, the sampling mechanism further includes a power source for providing power to the linear drive component. The linear drive component also includes a delivery pipe 233. The cylinder 231 includes a rod chamber and a rodless chamber. There are multiple delivery pipes 233, which are connected to the rod chamber and the rodless chamber in a one-to-one correspondence. All delivery pipes 233 pass through the second sampling section 13 and are connected to the power source.
[0027] Taking the existing linear drive component using a cylinder as an example, specifically, when concrete sampling is required, air is introduced into the rod chamber by the power source, and air is expelled from the rodless chamber, causing the piston rod 232 to retract, connecting the sampling port 401 with the discharge port 22, enabling sampling. After concrete sampling is completed, air is introduced into the rodless chamber by the power source, and air is expelled from the rod chamber, causing the piston rod 232 to extend and completely seal the sampling port 401 through the sealing component 21, preventing concrete from the collection hopper 40 from entering the storage space 11. Of course, the linear drive component of this application can also be in the form of a hydraulic cylinder, achieving the same effect.
[0028] like Figure 3 and Figure 4 As shown, in this embodiment, the sealing component 21 is made of wear-resistant material and is adapted to the inner wall surface of the first sampling part 12 to prevent the material in the collecting hopper 40 from entering the gap between the first sampling part 12 and the sealing component 21. The adjusting component 2 also includes a first locking component. There are multiple first locking components, and the sealing component 21 is detachably connected to the first end of the piston rod 232. It is easy to assemble and disassemble, and the number of first locking components can be adjusted according to actual needs.
[0029] like Figure 3 As shown, in this embodiment, the adjusting component 2 further includes a second locking fastener 5. A first flange 3 is provided on the outer wall surface of the material inlet 401, and a second flange 4 is connected to the outer peripheral wall of the first end of the first sampling part 12. Multiple second locking fasteners 5 are provided, and the first flange 3 and the second flange 4 are detachably connected, making disassembly and assembly convenient and providing good installation stability. It should be noted that both the first locking fastener and the second locking fastener 5 can be bolts as used in the prior art, which can ensure a stable installation between the collecting hopper 40 and the first sampling part 12, and between the first sampling part 12 and the second sampling part 13.
[0030] like Figure 3 As shown, in this embodiment, the feeding pipe 14 is connected to the storage space 11, and extends along the height direction of the collecting hopper 40. The end of the feeding pipe 14 opposite to the first sampling part 12 is the feeding port 22. Furthermore, both the first sampling part 12 and the second sampling part 13 are cylindrical structures with the same cross-sectional area, ensuring that the adjusting component 2 can smoothly extend and retract along the length of the sample body 1. Further, the cylindrical structure of the feeding pipe 14 results in better feeding performance.
[0031] like Figure 1 As shown, in this embodiment, a mixing plant is also proposed, including the sampling mechanism described above. Since the mixing plant adopts all embodiments of the sampling mechanism in this application, it also has all the beneficial effects of the sampling mechanism, which will not be described in detail here. The mixing plant includes a hopper 40 and a support frame 10 for supporting the hopper 40. The support frame 10 is also provided with a sampling platform 20 for carrying workers. The sampling platform 20 is set corresponding to the sampling mechanism. The sampling platform 20 can be a lifting sampling platform 20, which makes it easier for workers to climb onto the sampling platform 20 and supervise the sampling operation.
[0032] In this embodiment, the sampling mechanism includes a linear drive and a control unit connected to the linear drive. The control unit controls the opening and closing of the linear drive, and the sampling platform 20 is equipped with a control button connected to the control unit. Operators can conveniently control the extension and retraction of the linear drive on the sampling platform 20 via the control button, thereby controlling the timing of concrete sampling from the aggregate hopper 40. By controlling different operating intervals to retract the linear drive and discharge material, concrete samples can be collected from different locations. This solves the technical problem of limited concrete sampling in existing technologies and provides a more comprehensive reflection of the overall quality of the concrete.
