When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0046] The present application proposes an automatic sampling device and a ton bag unloading equipment, the automatic sampling device includes a receiving hopper 10, a sleeve 20, a limiting assembly 30 and a driving assembly 40, one side of the receiving hopper 10 is open, and a receiving cavity 11 is provided in the receiving hopper 10, and the receiving cavity 11 is connected to the opening; the sleeve 20 has a guide portion; the limiting assembly 30 is movably arranged in the guide portion; one end of the limiting assembly 30 is connected to the driving assembly 40, and the other end is connected to the receiving hopper 10; wherein, when the driving assembly 40 drives the limiting assembly 30 to move to one end of the guide portion, the opening faces upward; when the driving assembly 40 drives the limiting assembly 30 to move to the other end of the guide portion, the opening faces downward.

[0047] Referring to Figure 1 , the automatic sampling device interfaces with an external feeding device 70 and a sampling device 80. The feeding device 70 includes a feeding tube. During sampling, the automatic sampling device drives the receiving hopper 10 into the feeding tube, with the opening of the receiving hopper 10 facing upward. Material falling from the feeding tube falls through the opening into the receiving cavity 11. The sampling device 80 includes a funnel. During sample placement, the automatic sampling device drives the receiving hopper 10 above the funnel, with the opening of the receiving hopper 10 facing downward. Material in the receiving cavity 11 falls into the funnel and is collected by the sampling device 80.

[0048] To further ensure sealing and reduce the risk of material contamination, the automatic sampling device is further provided with a housing 50. Referring to Figures 2, 4, and 5, the housing 50 is cylindrical in shape, with two openings on its bottom. One end communicates with the sleeve 20, and the other end serves as the loading port 51, communicating with the feeding device 70. A discharge port 52 is also provided on the sidewall of the housing 50 for communicating with the sampling device 80.

[0049] It can be understood that the feed hole 52 and the feed hole 51 can be interchanged with each other, or adjusted to any position on the shell 50, specifically according to the application scenario, to correspond to the installation position of the feeding device 70 and the sample device 80.

[0050] When the driving assembly 40 pushes the limiting assembly 30 to move in the guide portion of the sleeve 20 , the limiting assembly 30 drives the receiving hopper 10 to move synchronously in the housing 50 . The receiving hopper 10 is movably disposed in the housing 50 .

[0051] Referring to Figure 4 , when the drive assembly 40 drives the stop assembly 30 to the rightmost end of the sleeve 20, the hopper 10 extends from the loading hole 51 into the feeding device 70, with its opening facing upward, to collect the material that falls. During the sampling process, only the hopper 10 of the automatic sampling device extends into the feeding device to receive the material; no other moving parts come into direct contact with the material.

[0052] 5 , when the driving assembly 40 drives the limiting assembly 30 to move to the leftmost end of the sleeve 20 , the receiving hopper 10 moves just above the discharge hole 52 with its opening facing downward, thereby pouring the collected material into the sample device 80 .

[0053] To enable the opening of the hopper 10 to flip up and down, the guide portion is divided into two parts. Referring to Figure 3 , the guide portion includes a first guide groove 21 and a second guide groove 22. The first guide groove 21 is located on the leftmost side of the sleeve 20 and is spiral-shaped. The second guide groove 22 is straight-line-shaped, with one end connected to the first guide groove 21 and the other end extending to the rightmost side of the sleeve 20.

[0054] When the first guide groove 21 is spiral, when the driving assembly 40 drives the limiting assembly 30 to move to the far left, under the guiding action of the first guide groove 21, the limiting assembly 30 will rotate half a circle around the side wall of the sleeve 20, that is, the limiting assembly 30 rotates 180°. The receiving hopper 10 is connected to the limiting assembly 30, and therefore rotates 180° synchronously with the limiting assembly 30, causing the receiving hopper 10 to flip over.

[0055] The position of the first guide groove 21 is adjusted so that the opening of the receiving hopper 10 remains facing upward when the limiting assembly 30 moves to the position where the first guide groove 21 and the second guide groove 22 connect. The second guide groove 22 is straight or straight, so when the limiting assembly 30 moves in the second guide groove 22, the opening of the receiving hopper 10 will not flip over.

[0056] It can be understood that the length of the shell 50 or the distance between the feeding device 70 and the sample device 80 is measured in advance, and the length of the second guide groove 22 is adjusted accordingly, so as to ensure that when the limiting assembly 30 moves to the far left, the position of the receiving hopper 10 corresponds to the sample device 80, and when it moves to the far right, the position of the receiving hopper 10 corresponds to the feeding device 70.

[0057] To enhance the stability of the fit between the stop assembly 30 and the guide portion on the sleeve 20, the stop assembly 30 includes a connecting rod 31, a bearing 32, and a stop rod 33. The connecting rod 31 is also cylindrical, with its length parallel to the sleeve 20, and is mounted within the sleeve 20. The connecting rod 31 is aligned with the center of the sleeve 20 to facilitate the installation of the bearing 32 between the sleeve 20 and the connecting rod 31. The inner ring of the bearing 32 is connected to the connecting rod 31, and the outer ring is connected to the side wall of the sleeve 20. This prevents the connecting rod 31 from interfering with other components during rotation.

[0058] The limiting rod 33 is vertically connected to the connecting rod 31, and its end extends toward the guide portion until it protrudes out of the guide portion, that is, extends out of the sleeve 20 through the first guide groove 21 and the second guide groove 22, so as to facilitate connection with the drive assembly 40.

[0059] The driving assembly 40 is connected to the limiting rod 33 and pushes the limiting rod 33 to move along the first guide groove 21 and the second guide groove 22. The width of the first guide groove 21 and the second guide groove 22 is adapted to the width of the limiting rod 33.

[0060] The connection position between the first guide groove 21 and the second guide groove 22 is a smooth transition connection, thereby preventing the limiting rod 33 from getting stuck when the driving assembly 40 drives the limiting rod 33 to move to this position.

[0061] The drive assembly 40 may be a screw module 41, specifically comprising a motor 412 and a threaded rod 411. The motor 412 drives the threaded rod 411 to rotate. A screw seat is provided on the threaded rod 411, and a connecting plate 42 is mounted on the screw seat. When the threaded rod 411 rotates, the screw seat moves along the length of the threaded rod 411, driving the connecting plate 42 to move.

[0062] The connecting plate 42 is connected to the limiting rod 33 , thereby driving the limiting rod 33 to move left and right.

[0063] In order to prevent the connecting plate 42 from shifting in position during movement, the driving assembly 40 is further equipped with a guide rod 43. The guide rod 43 can be arranged inside the sleeve 20 or on either side outside the sleeve 20, so that the guide rod 43 and the sleeve 20 are parallel.

[0064] A corresponding guide hole is opened on the connecting plate 42, and the guide rod 43 is installed through the guide hole during assembly, so that during the movement of the connecting plate 42, the connecting plate 42 moves along the extension direction of the guide rod 43 without positional offset.

[0065] The technical solution of this application utilizes a single drive assembly 40, which drives the hopper 10 through the cooperation of the sleeve 20 and the limit assembly 30. This means that the drive assembly 40 can be completely externalized and not in direct contact with the material, reducing the risk of material contamination. During the sampling process, only the hopper 10 receives the material, and after sampling, the automatic sampling device will not come into contact with the material again, further reducing the risk of material contamination and improving product quality.

[0066] Referring to Figures 4 and 5 , the limiting assembly 30 also includes an oil seal 34, which is disposed between the connecting rod 31 and the sleeve 20. To prevent material from falling into the sleeve 20 during sampling, thereby affecting normal operation, the oil seal 34 is disposed between the connecting rod 31 and the sleeve 20. The oil seal 34 is located on the side of the sleeve 20 near the housing 50 to isolate the material from the hopper 10.

[0067] In addition, the automatic sampling device further includes an inflatable sealing ring 60, which is disposed at the edge of the feeding hole 51. In order to prevent material from entering the housing 50, an inflatable sealing ring 60 is further disposed on one side of the housing 50 near the feeding device 70.

[0068] When the equipment stops running, the hopper 10 retracts into the housing 50. The inflatable sealing ring 60 seals the feed hole 51 and the feeding device to prevent the material from entering the housing 50 without affecting the normal transportation of the material.

[0069] After the receiving hopper 10 receives the material, the inflatable sealing ring 60 can be opened to fill the gap between the receiving hopper 10 and the housing 50, isolating the excess material in the receiving hopper 10. The inflatable sealing ring 60 can be used in an environment where the material is conveyed under pressure, thereby avoiding the occurrence of dust spraying.

[0070] Further, referring to Figure 6 , the connecting rod 31 includes an air passage 35, one end of which communicates with the material receiving chamber 11 and the other end with an external air source. This air source allows air to be blown into the material receiving chamber 11. When the material receiving hopper 10 is moved to a position corresponding to the sampling device 80, the air source is activated, allowing air to flow into the material receiving chamber 11, causing the material remaining in the chamber 11 to fall into the sampling device 80, preventing cross-contamination caused by the remaining material when sampling other types of samples.

[0071] In addition, in order to solve the above problems, the present application also proposes a ton bag unloading equipment, and the ton bag unloading equipment is applied with the automatic sampling device as described above. Only a single drive component 40 is used for driving, and the drive component 40 drives the receiving hopper 10 to move through the cooperation of the sleeve 20 and the limit component 30. That is, the drive component 40 can be completely external and not in direct contact with the material, reducing the risk of material contamination. During the sampling process, only the receiving hopper 10 is used to receive the material. After sampling, the automatic sampling device will not come into contact with the material again, further reducing the material contamination direction and improving product quality.

[0072] The above description is only a preferred embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made by using the contents of the present application description and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
