Abstract
Description
Technical Field
[0001] This invention relates to the field of sampling device technology, and in particular to a high-efficiency sampling device for metal processing. Background Technology
[0002] During the metal processing stage, it is necessary to sample the powdered raw materials. Sampling should be done randomly from different locations and depths to ensure the representativeness of the sample. Multiple sampling and analysis are usually required to ensure the accuracy of the sample analysis.
[0003] Existing sampling devices extract samples by inserting a sampling tube into the raw material. This method has several drawbacks: First, the sample volume varies each time because the internal stress of the raw material differs after the sampling tube is inserted, resulting in variations in the amount sampled each time. Second, the sampled material needs to be thoroughly mixed in a mixing device after sampling to ensure the accuracy of the test results, which is cumbersome. Third, there are intervals between each sampling, making it impossible to continuously sample the raw material from the material conveying trough, leading to significant differences in the test results. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in the prior art, such as differences in sampling volume, the need for uniform mixing after sampling, and the intermittent nature of sampling, which lead to inaccurate test results, wasted time in subsequent mixing, increased testing time, and large differences in test results. Therefore, this invention proposes a high-efficiency sampling device for metal processing.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A high-efficiency sampling device for metal processing includes a sampling drum with an internal cavity. A central track cylinder is inserted into the cavity. A descending slope is formed on the side of the central track cylinder. Several arc-shaped contact plates are tightly fitted to the surfaces of the central track cylinder and the descending slope. The arc-shaped contact plates are arranged in a circular array around the central track cylinder. A sampling collection plate is fixed to the surface of each arc-shaped contact plate. The sampling collection plate is L-shaped. A compression spring is fixed at the corner of each arc-shaped contact plate. One end is tightly fitted to the inner wall of the sampling roller. The sampling roller has several through slots on its side, and one end of the sampling collection plate is inserted into the inner wall of the through slot. The through slot and the sampling collection plate are matched. A driving component is provided on one side of the sampling roller, and a support component is provided on one side of the central track cylinder. Both the driving component and the support component have fixing components on their sides. A conveying component is provided on the outer wall of the sampling roller. A lifting component is provided at the bottom of the conveying component. A rotating component is provided at the bottom of the lifting component. A mold component is provided at the bottom of the rotating component.
[0007] Preferably, the drive assembly includes a meshing groove formed on one side of the sampling drum, and a drive motor is inserted into the inner wall of the meshing groove.
[0008] Preferably, the support assembly includes a support shaft fixed to the inner wall of the central hole of the central track cylinder, with one end of the support shaft penetrating through the inner wall of the central hole on the other side of the sampling cylinder.
[0009] Preferably, the fixing component includes a side plate support frame sleeved on the outside of the drive motor and the outside of one end of the support shaft, and the bottom of the side plate support frame is provided with a through hole.
[0010] Preferably, the conveying assembly includes a sample conveying trough that fits tightly against the outer arc surface of the sampling roller, a fixing hole is provided on the side of one end of the sample conveying trough, and a discharge port is provided at the bottom of one end of the sample conveying trough.
[0011] Preferably, the lifting assembly includes a pneumatic lifting rod fixed to the bottom of the outlet end of the sample conveying trough. There are four pneumatic lifting rods, and the four pneumatic lifting rods are arranged in a circular array with the outlet as the axis.
[0012] Preferably, the rotating assembly includes a connecting collar fixed to the bottom of the pneumatic lifting rod, and the connecting collar is coaxial with the discharge port. A rotatable rotating ring is inserted into the inner wall of the connecting collar. A rotary motor is fixed to the side of the connecting collar. A meshing disc is fixed to the output end of the rotary motor. The side of the meshing disc passes through the connecting collar and fits tightly against the outer side of the rotating ring. Several external feet are fixed to the bottom of the rotating ring.
[0013] Preferably, the mold assembly includes a folding arm hinged to the bottom of the outer foot via a shaft, the bottom end of the folding arm being hinged to a positioning seat via a shaft, and a surrounding plate being fixed to the side of the positioning seat, and several surrounding plates can be enclosed in a conical shape.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0015] 1. This invention utilizes a combination of a central track cylinder and a descending slope. The sampling drum is driven by a motor to rotate within the raw material conveying trough. After the sampling drum rotates, the arc-shaped contact plate rotates around the central track cylinder and the descending slope, causing the sampling collection plate to extend from the bottom of the sampling drum to collect samples. This sampling method ensures that the amount of sample taken each time is the same and that sampling from the raw material conveying trough is continuous, avoiding significant differences in test results and improving sampling quality. The sampling process occurs while the raw material is being conveyed within the raw material conveying trough, ensuring sampling quality. Furthermore, after the sampling collection plate retracts from the top of the sampling drum, the sample slides off the surface of the sampling drum, is mixed, and then sent out.
[0016] 2. The present invention uses a combination of sampling roller and sampling collection plate. The sampling collection plate extends from the bottom of the sampling roller and takes samples from the bottom of the conveyor belt that transports the raw materials upward. This process can ensure that the amount of samples taken each time is the same, and can ensure that the samples collected by each set of sampling collection plates are samples from different points and heights, which greatly improves the accuracy of sampling results detection.
[0017] 3. The present invention, through the setting of the sampling roller, which is placed in the raw material conveying trough, ensures that the raw material is continuously conveyed in the raw material conveying trough. With the rotating sampling roller, the raw material can be sampled continuously during the conveying process, thereby ensuring that the test results are consistent throughout the entire raw material conveying process and improving the accuracy of the test results.

[0028] Example, refer to Figures 1 to 6 A high-efficiency sampling device for metal processing includes a sampling drum 1 with an internal cavity. A central track cylinder 2 is inserted into the cavity of the sampling drum 1. A descending slope 3 is formed on the side of the central track cylinder 2. Several arc-shaped contact plates 4 are tightly attached to the surfaces of the central track cylinder 2 and the descending slope 3. The arc-shaped contact plates 4 are arranged in a circular array around the central track cylinder 2. A sampling collection plate 5 is fixed to the surface of the arc-shaped contact plate 4. The sampling collection plate 5 is L-shaped. A compression spring 6 is fixed at the corner of the arc-shaped contact plate 4 and the corner of the sampling collection plate 5. One end of the compression spring 6 is tightly attached to the inner wall of the sampling drum 1. Several through slots 7 are formed on the side of the sampling drum 1, and one end of the sampling collection plate 5 is inserted into the inner wall of the through slot 7. The through slots 7 and the sampling collection plate 5 are matched.
[0029] Driven by the drive motor 9, the sampling roller 1 rotates, which synchronously drives the sampling collection plate 5 in the through groove 7 to rotate and collect samples. When the sampling collection plate 5 rotates with the sampling roller 1, the arc-shaped contact plate 4 at the bottom of the sampling collection plate 5 moves around the central track cylinder 2 and the descending slope 3, thereby realizing the extension and retraction process of the sampling collection plate 5 to complete the sampling work. The compression spring 6 ensures that the bottom of the arc-shaped contact plate 4 is always in contact with the central track cylinder 2 and the descending slope 3. The sampling collection plate 5 extends from the bottom of the sampling roller 1 to collect samples and retracts from the top of the sampling roller 1. When the sampling collection plate 5 begins to retract, the raw material slides down the surface of the sampling roller 1. The sample completes the first stage of mixing during the sliding process. The second stage of mixing occurs when the sample is conveyed in the sample conveying groove 12. The third stage of mixing occurs after the sample is discharged from the outlet 13. Through the three stages of mixing, the sample is completely mixed, which improves the accuracy of the test results.
[0030] A drive assembly is provided on one side of the sampling roller 1. Further, the drive assembly includes a meshing groove 8 opened on one side of the sampling roller 1, and a drive motor 9 is inserted into the inner wall of the meshing groove 8.
[0031] A further advantage of the above is that the output end of the drive motor 9 can be connected to the sampling roller 1 through the meshing groove 8, so that the drive motor 9 can drive the sampling roller 1 to rotate after being powered on.
[0032] A support assembly is provided on one side of the central track cylinder 2. Further, the support assembly includes a support shaft 10 fixed to the inner wall of the central hole of the central track cylinder 2, and one end of the support shaft 10 penetrates the inner wall of the central hole on the other side of the sampling cylinder 1.
[0033] A further advantage of the above is that the support shaft 10 can support the central track cylinder 2 inside the sampling drum 1, so as to ensure that the arc-shaped contact plate 4 can slide along the central track cylinder 2 and the descending slope 3.
[0034] Furthermore, both the drive assembly and the support assembly are provided with fixing components on their sides. The fixing components include a side plate support frame 11 that is sleeved on the outside of the drive motor 9 and the outside of one end of the support shaft 10, and the bottom of the side plate support frame 11 is provided with a through hole.
[0035] A further advantage of the above is that the side plate support frame 11 can fix the device to the existing support structure so that the sampling roller 1 can drive the sampling collection plate 5 to take samples in the raw material conveying trough.
[0036] The outer wall of the sampling roller 1 is provided with a conveying assembly. Further, the conveying assembly includes a sample conveying groove 12 that is closely fitted to the outer arc surface of the sampling roller 1. A fixing hole is opened on the side of one end of the sample conveying groove 12, and a discharge port 13 is opened at the bottom of one end of the sample conveying groove 12.
[0037] The further advantage of the above is that the sample conveying trough 12 can convey the sample discharged from the sampling collection plate 5 and can assist in completing the sample mixing process. The sample conveying trough 12 is connected to the external frame by bolts.
[0038] The bottom of the conveying assembly is provided with a lifting assembly. Further, the lifting assembly includes a pneumatic lifting rod 14 fixed to the bottom of one end of the discharge port 13 of the sample conveying trough 12. There are four pneumatic lifting rods 14, and the four pneumatic lifting rods 14 are arranged in a circular array with the discharge port 13 as the axis.
[0039] The further advantage of the above is that the pneumatic lifting rod 14 can drive the enclosure plate 22 to open and flatten the sample through the folding arm 20, or the enclosure plate 22 can be spliced into a cone shape to collect the sample, so as to better obtain the sample by the quartering method.
[0040] The bottom of the lifting assembly is provided with a rotating assembly. Further, the rotating assembly includes a connecting collar 15 fixed to the bottom of the pneumatic lifting rod 14, and the connecting collar 15 is coaxial with the discharge port 13. A rotatable rotating ring 16 is inserted into the inner wall of the connecting collar 15. A rotary motor 17 is fixed to the side of the connecting collar 15. A meshing disc 18 is fixed to the output end of the rotary motor 17. The side of the meshing disc 18 passes through the connecting collar 15 and fits tightly against the outer side of the rotating ring 16. Several external feet 19 are fixed to the bottom of the rotating ring 16.
[0041] A further advantage of the above is that the rotary motor 17 can drive the rotary ring 16 to rotate, so as to spread the collected sample material flat and mix it.
[0042] The bottom of the rotating assembly is provided with a mold assembly. Further, the mold assembly includes a folding arm 20 that is hinged to the bottom of the outer foot 19 via a shaft. The bottom end of the folding arm 20 is hinged to a positioning seat 21 via a shaft. A surrounding plate 22 is fixed to the side of the positioning seat 21. Several surrounding plates 22 can be enclosed in a cone shape.
[0043] A further advantage of the above is that during the extension and retraction of the pneumatic lifting rod 14 at the conveying end, the folding arm 20 can drive the enclosure plate 22 to be spliced into a cone shape to collect the sample, or the enclosure plate 22 can be unfolded into a planar mixed sample.
[0044] In use, the drive motor 9 is powered on and drives the sampling roller 1 to rotate in the raw material conveying trough. When the sampling collection plate 5 rotates with the sampling roller 1, the arc-shaped contact plate 4 rotates around the central track cylinder 2 and the descending slope 3. The sampling collection plate 5 extends from the bottom of the sampling roller 1 through the through groove 7 to collect the sample. After rotating to the top of the sampling roller 1 and contacting the descending slope 3, it begins to retract. At this time, the sample slides from the side of the sampling roller 1 into the sample conveying trough 12 and is discharged from the outlet 13 into the conical barrel formed by the enclosing plate 22. After the sample is full, the pneumatic lifting rod 14 extends out and drives the connecting collar 15 to descend. When the connecting collar 15 descends, it drives the enclosing plate 22 to open on the plate surface to form a plane through the folding arm 20. During the descent of the rotating ring 16, the rotating motor 17 works to drive the enclosing plate 22 to rotate and flatten the mixed sample through the rotating ring 16, so as to facilitate the subsequent collection of the sample using the quartering method.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
