Description

Technical Field

[0001] This invention relates to the field of sampling equipment, and in particular to a multi-directional sampling device and method for ton bags. Background Technology

[0002] After receiving the materials from the ton bags, the materials need to be tested, such as the content of magnetic substances in the materials and the quality of materials at different depths in the ton bags. Because the ton bags are relatively large in weight and volume, and the existing sampling method involves manual insertion, sampling, and then pulling out, the friction increases with depth during the insertion process, making insertion more difficult.

Detailed Implementation

[0035] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] See Figures 1-11 The present invention provides a technical solution:

[0037] A multi-directional sampling device for ton bags includes a base 1, side sampling devices, side sealing devices, a ton bag transport device, and a top sampling device. The ton bag transport device is fixedly mounted on the base 1 and is used to transport sample ton bags 2. The base 1 is equipped with several side sampling devices that cooperate with the sides of the sample ton bags 2. The side sealing devices are fixedly mounted on the base 1 and cooperate with the sample ton bags 2. The base 1 is also equipped with a top sampling device that cooperates with the top of the sample ton bags 2. The side sampling devices, side sealing devices, ton bag transport device, and top sampling device are all electrically connected to a control box 3. The control box 3 is a control center in the prior art; under the control of the control box 3, the side sampling devices, side sealing devices, ton bag transport device, and top sampling device work together to achieve sampling. The equipment base 1 is used to install the side sampling device, the side sealing device, the ton bag transport device, and the top sampling device. The ton bag transport device is used to transport the sample ton bag 2. After the sample ton bag 2 is transported to the preset position, the side sampling device and the top sampling device are inserted into the sample ton bag 2 to take samples. In this technology, there are four sets of side sampling devices. Each set of side sampling devices takes samples at different heights in the sample ton bag 2. Each set of side sampling devices is equipped with a set of side sealing devices. The side sampling device leaves a sampling port on the sample ton bag 2. The side sealing device uses tape to seal the sampling port on the sample ton bag 2, thus preventing the sampling port on the sample ton bag 2 from being open and causing material to flow out. In actual operation, the side sampling device and the top sampling device can be inserted simultaneously without interference between them. Alternatively, the side sampling device can be selected to sample first and the top sampling device to sample later, or the top sampling device can be selected to sample first and the side sampling device to sample later.

[0038] In some embodiments, the top sampling device includes a top sampling frame 4, a sliding frame 5, a sliding drive 6, a first sampling drive 7, a second sampling drive 8, a sampling guide plate 9, a magnetic sampling rod 10, a magnetic piercing terminal 11, a sampling outer tube 12, a sampling inner tube 13, and a sealing piercing terminal 14. The top sampling frame 4 is fixedly mounted on the equipment base 1. The sliding frame 5 is slidably mounted on the top sampling frame 4. The sliding drive 6 is mounted on the sliding frame 5 and is used to drive the sliding frame 5 to slide. The sampling guide plate 9 is slidably mounted on the sliding frame 5. The first sampling drive 7 is fixedly mounted on the upper end of the sliding frame 5 and is used to drive the sampling guide plate 9 to move. The upper end of the magnetic sampling rod 10 is fixedly mounted on the sampling guide plate 9. The magnetic piercing terminal 11 is fixedly mounted on the lower end of the magnetic sampling rod 10 and cooperates with the sample ton bag 2. A sampling slot 18 is provided on the side. The upper end of the sampling outer tube 12 is fixedly mounted on the sampling guide plate 9. The sampling inner tube 13 is slidably mounted inside the sampling outer tube 12 and cooperates with the sampling outer tube 12.

The fixing part of the second sampling drive 8 is fixedly mounted on the sampling guide plate 9. The sealing and fixing of the sealing and puncturing terminal 14 is fixedly mounted on the lower end of the sampling inner tube 13 and cooperates with the sampling outer tube 12. The sampling outer tube 12 is provided with multiple first feed ports 15. The sampling inner tube 13 is provided with multiple second feed ports 16 that cooperate with the first feed ports 15. The lower end of the sampling inner tube 13 is provided with a discharge port 17. The lower end of the sliding frame 5 is provided with a magnetic guide hole that cooperates with the magnetic sampling rod 10. The lower end of the sliding frame 5 is provided with a sampling guide hole that cooperates with the sampling outer tube 12. The lower end of the top sampling frame 4 is fixed to the equipment base 1. A slide rail is provided on the top of the top sampling frame 4, and the sliding frame 5 slides to both sides of the slide rail. The two ends of the slide rail are respectively engaged with the magnetic material collection chamber 23 and the sample material collection chamber 24. The sliding drive component 6 and the first sampling drive component 7 are both motors in the prior art and are electrically connected to the control box 3. The sliding drive component 6 and the first sampling drive component 7 are both fixedly mounted on the sliding frame 5. A gear is fixedly mounted on the output part of the sliding drive component 6, and a rack that engages with the gear is fixedly mounted on the top sampling frame 4. The rack is arranged parallel to the slide rail. A guide rod is provided between the upper and lower ends of the sliding frame 5, and the sampling guide plate 9 slides on the guide rod. A transmission screw is fixedly mounted on the output part of the first sampling drive component 7. The transmission screw is threadedly engaged with the sampling guide plate 9. The sampling guide plate 9 is used to fix and install the magnetic sampling rod 10, the second sampling drive component 8, and the sampling outer tube 12.The magnetic guide hole guides the movement of the magnetic sampling rod 10. Simultaneously, the magnetic material on the magnetic sampling rod 10 is pushed to its lower end by the magnetic guide hole and finally falls into the magnetic material collection chamber 23. The diameter of the magnetic piercing terminal 11 is larger than the diameter of the magnetic sampling rod 10. Three, four, or more sampling slots 18 are provided on the side of the magnetic piercing terminal 11. These sampling slots 18 allow for the creation of a larger sampling hole in the sample ton bag 2, preventing the sample ton bag 2 from rubbing against the support of the magnetic sampling rod 10 and thus preventing the magnetic material on the magnetic sampling rod 10 from being removed from the sample ton bag 2. The sampling guide hole guides the movement of the sampling outer tube 12, preventing it from bending and breaking. The outer wall of the sampling inner tube 13 mates with the inner wall of the sampling outer tube 12. The second sampling drive component 8 is a pneumatic or hydraulic cylinder as used in the prior art. The pneumatic or hydraulic cylinder is controlled by a control valve, which is electrically connected to the control box 3. The second sampling drive 8 is fixed on the sampling guide plate 9 and pushes the sampling inner tube 13 to slide inside the sampling outer tube 12. When the second sampling drive 8 is not working, the sealing and piercing terminal 14 also contacts the sampling outer tube 12. The first feed port 15 is blocked by the sampling inner tube 13, and the second feed port 16 is blocked by the sampling outer tube 12. At this time, the sample material cannot enter the sampling inner tube 13 through the first feed port 15 and the second feed port 16. At the same time, the discharge port 17 is blocked by the sampling outer tube 12 and cannot discharge. When the second sampling drive 8 pushes the sampling inner tube 13 downward, the first feed port 15 and the second feed port 16 cooperate, and the material in the sample ton bag 2 enters the sampling inner tube 13 through the first feed port 15 and the second feed port 16, and also enters the sampling inner tube 13 through the discharge port 17. When it is above the sample material collection chamber 24, the material in the sampling inner tube 13 enters the sample material collection chamber 24 through the second feed port 16 and the first feed port 15, and at the same time, the material at the lower end of the sampling inner tube 13 enters the sample material collection chamber 24 through the discharge port 17.

[0039] In some embodiments, a first guide slope 20 that mates with the inner wall of the lower end of the sampling inner tube 13 is provided, and a second guide slope 21 that mates with the first guide slope 20 is provided on the discharge port 17. A protective ring 22 that mates with the end of the sampling outer tube 12 is fixedly provided on the outer wall of the sealing and puncturing terminal 14. The first guide slope 20 and the second guide slope 21 are provided to ensure that all the material sample in the sampling inner tube 13 is discharged completely. The diameter of the protective ring 22 is not less than the diameter of the sampling outer tube 12 to prevent the sampling outer tube 12 from being damaged by friction during long-term sampling.

[0040] In some embodiments, the top sampling device further includes a magnetic material collection chamber 23, a sample material collection chamber 24, a collection tray 25, a weighing meter 26, and a container platform 27. The magnetic material collection chamber 23 is fixedly mounted on one end of the top sampling frame 4 and cooperates with the magnetic sampling rod 10. The sample material collection chamber 24 is fixedly mounted on the other end of the top sampling frame 4 and cooperates with the sampling inner tube 13. Both the magnetic material collection chamber 23 and the sample material collection chamber 24 are provided with a discharge port 19 at their lower ends. Both the magnetic material collection chamber 23 and the sample material collection chamber 24 are provided with a container platform 27 that cooperates with the discharge port 19 at their lower ends. The container platform 27 is provided with a weighing meter 26, and the weighing meter 26 is provided with a collection tray 25 that cooperates with the discharge port 19 of the magnetic material collection chamber 23. The magnetic material collection chamber 23 is used to collect magnetic materials from the material. When the sliding frame 5 moves above the magnetic material collection chamber 23, the first sampling drive 7 drives the sampling guide plate 9 to continue moving upward. The magnetic sampling rod 10 connected to the sampling guide plate 9 scrapes against the magnetic guide hole, and the magnetic material on the magnetic sampling rod 10 falls into the magnetic material collection chamber 23. Finally, it enters the collection tray 25 through the discharge port 19. The collection tray 25 is placed on the weighing meter 26 in the prior art, and the weighing meter 26 displays the mass of the magnetic material. The container platform 27 on the lower side of the magnetic material collection chamber 23 is used to install the weighing meter 26. A collection container is placed on the container platform 27 below the sample material collection chamber 24. After placing the collection container on the container platform 27, the sliding frame 5 is moved to the top of the sample material collection chamber 24. The second sampling drive unit 8 is controlled to push the sampling inner tube 13 downward. At this time, the first feed port 15 and the second feed port 16 cooperate, and the discharge port 17 is not blocked by the sampling outer tube 12. After the material enters the sample material collection chamber 24, it enters the collection container through the discharge port 19.

The first pressing plate 50 is connected to the sealing mounting bracket 34 via a first tension spring 59, and the second pressing plate 52 is connected to the sealing mounting bracket 34 via a second tension spring 60. A cutting blade 47 for cutting the tape 58 is provided on the output section of the cutting drive 46. The winding drive 48 is a motor (as in the prior art), and the locking drive 57 and cutting drive 46 are both pneumatic or hydraulic cylinders (as in the prior art). Each pneumatic or hydraulic cylinder is controlled by a different solenoid valve. Both the winding drive 48 and the solenoid valves are electrically connected to the control box 3. The sealing mounting bracket 34 is used to install the cutting drive 46, the winding drive 48, the first clamping plate 50, the second clamping plate 52, the stabilizing wheel 54, and the locking drive 57. In this technology, the tape 58 is a double-sided tape. The adhesive portion of the double-sided tape is cut off by the cutting blade 47 to seal the sample ton bag 2. The unadhesive portion of the double-sided tape (i.e., the waste portion) is not cut off and is wound onto the winding shaft 49. The winding drive 48 drives the winding shaft 49 to rotate, and the cutting drive 46 drives the cutting blade 47 to perform the cutting operation. One end of the first pressing plate 50 and the second pressing plate 52 are both hinged to the sealing mounting bracket 34. The first pressing plate 50 is located near the locking drive member 57. The first pressing plate 50 presses on the uncut tape 58 on the winding shaft 49, and the second pressing plate 52 presses on the unattached part of the winding shaft 49. The adhesive part on the tape 58 extends from between the first pressing wheel 51 and the second pressing wheel 53 and can be cut by the cutting blade 47. The first tension spring 59 and the second tension spring 60 respectively tighten the other end of the first pressing plate 50 and the other end of the second pressing plate 52, so that the first pressing plate 50 and the second pressing plate 52 generate greater pressure to prevent the tape 58 from deviating when it is cut.First connecting posts are provided on the first pressing plate 50 and the first pressing wheel 51. Two second connecting posts are provided on the sealing mounting bracket 34. One end of the first tension spring 59 and the second tension spring 60 are respectively connected to the two first connecting posts, and the other ends of the first tension spring 59 and the second tension spring 60 are respectively connected to the two second connecting posts. Two stabilizing wheels 54 are provided. The usable end of the tape 58 passes through the space between the two stabilizing wheels 54. The locking drive 57 is fixed to the sealing mounting bracket 34 and drives the locking seat 55 to move up and down. The locking seat 55 is provided with three or four sets of locking rollers 56. The three or four sets of locking rollers 56 cooperate with the two stabilizing wheels 54 to clamp the unused tape 58 in the middle. As the tape 58 is used less, the locking drive 57 will drive the locking seat 55 to move upward. The stabilizing wheel 54, locking roller 56, winding shaft 49, first pressing wheel 51, and second pressing wheel 53 are all arranged parallel to each other.

[0044] In some embodiments, the ton bag transport device includes transport wheels 61, a transport drive component 62, a first chain 63, and a second chain 64. The transport wheels 61 are rotatably mounted on the equipment base 1. The transport drive component 62 is fixedly mounted on the equipment base 1 and drives the transport wheels 61 to rotate via the first chain 63. Adjacent transport wheels 61 are connected by the second chain 64. The transport drive component 62 is a motor, as in the prior art, and is electrically connected to the control box 3. The gears on the transport drive component 62 drive the gears on the transport wheels 61 to rotate via the first chain 63. The gears on the transport wheels 61 are fixedly connected to the transport wheels 61, thereby driving the transport wheels 61 to rotate. The transport wheels 61 on the equipment base 1 are evenly spaced, and adjacent transport wheels 61 are connected by the second chain 64, thus ensuring that all transport wheels 61 rotate synchronously. Multiple existing detection sensors are installed at the center of the equipment base 1. Detection by these sensors ensures that the sample ton bag 2 reaches a preset position, facilitating subsequent sampling.

[0045] In some embodiments, a main travel wheel 65 is provided on the middle of the equipment base 1, and a movable drive component 66 for driving the main travel wheel 65 to rotate is fixedly provided on the equipment base 1. Rotary disks 67 are rotatably provided on both ends of the equipment base 1, and steering wheels 68 and steering handles 69 are provided on the rotating disks 67. The movable drive component 66 is a motor as in the prior art and is electrically connected to the control box 3. The movable drive component 66 drives the main travel wheel 65 to rotate, thereby moving the entire equipment. The steering handles 69 drive the rotating disks 67 to rotate on the equipment base 1, thereby controlling the direction of movement of the equipment base 1.

[0046] A sampling method for ton bags, using a multi-directional sampling device for ton bags, includes the following steps:

[0047] (1) First, place the sample ton bag 2 on one end of the ton bag transport device; since each sample ton bag 2 needs to be sampled, in order to improve efficiency, feed from one end of the ton bag transport device and unload from the other end.

[0048] (2) The sample ton bag 2 is transported to the middle of the equipment base 1 by the control box 3, and the side sampling device and the top sampling device are both in conjunction with the sample ton bag 2. The side sampling device and the top sampling device can sample at the same time or separately. There is no order of sampling when sampling separately.

[0049] (3) Control the side sampling device and the top sampling device to insert into the sample ton bag 2 for sampling through the control box 3. After sampling is completed, control the side sampling device and the top sampling device to pull out the sample ton bag 2.

[0050] (4) The side sealing device is controlled by the control box 3 to seal the sampling hole left on the sample ton bag 2 by the tape 58. The side sampling device seals the sampling hole left on the sample ton bag 2 by the tape 58 to prevent the material on the sample ton bag 2 from being discharged through the sampling hole.

[0051] (5) Finally, the sample ton bag 2 after sampling is transported to the other end of the ton bag transport device by the control box 3.
