[0001] The utility model belongs to the technical field of sampling device equipment, and specifically relates to a detachable closed sampler. Background Art

[0002] During the sampling process of the existing sampler or after the sampling is completed, when the material is transferred from the sampler to the sampling bag or sampling box, the moisture content of the material does not match the actual moisture content in the silo after contacting the atmosphere, resulting in the detection data not matching the actual data. For example, the Chinese utility model patent with the publication number CN213956867U discloses "a detachable sleeve type powder sampler", which performs sealed sampling by slidingly connecting a sealing sleeve to the side of a collection sleeve. This sampling method has poor sealing effect and is inconvenient to disassemble and assemble.

[0008] Preferably, at least two sampler sealing rings are arranged on the outer circumferential surfaces of both sealing columns.

[0009] Preferably, one end of the sampler main rod is provided with a main rod threaded end, and the sealing column close to the sampler main rod is provided with a connecting threaded end, and the main rod threaded end and the connecting threaded end are connected by a connecting nut.

[0010] Preferably, one end of the outer wall cylinder of the sampler is provided with an outer wall cylinder threaded end. A limiting ring is provided at one end of the main rod of the outer wall cylinder of the sampler close to the outer wall cylinder of the sampler. An outer wall cylinder connecting nut is sleeved on the side of the limiting ring away from the outer wall cylinder of the sampler. The outer wall cylinder of the sampler is connected to the main rod of the outer wall cylinder of the sampler by connecting the outer wall cylinder connecting nut to the outer wall cylinder threaded end.

[0011] Preferably, a groove of the main rod of the outer wall cylinder of the sampler is provided at one end of the main rod of the outer wall cylinder of the sampler away from the outer wall cylinder of the sampler. A positioning pin of the main rod of the sampler is provided at the outer ring of one end of the main rod of the sampler away from the sampler.

Specific embodiments

[0025] The following is a further specific description of the technical solution of the present utility model through examples and in combination with the attached Figures 1 - 7 structure shown.

[0026] Embodiment 1: A detachable and sealed sampling device, including a sampling device body and an operating rod connected to the sampling device body. The sampling device body includes an outer wall cylinder 4 of the sampling device and a sampling device 1 arranged inside the outer wall cylinder 4 of the sampling device. The operating rod includes a main rod 10 of the outer wall cylinder of the sampling device and a main rod 9 of the sampling device arranged inside the main rod 10 of the outer wall cylinder of the sampling device in a pull-out manner.

[0027] The sampling device 1 includes a connecting rod 101 and sealing columns 102 arranged at both ends of the connecting rod 101.

[0028] Among them, the outer wall cylinder 4 of the sampling device is detachably connected to the main rod 10 of the outer wall cylinder of the sampling device, and the sealing column 102 on the side close to the main rod 9 of the sampling device is detachably connected to the main rod 9 of the sampling device.

[0029] The specific implementation method is:

[0030] By operating the main rod 9 of the sampling device to expand and contract inside the main rod 10 of the outer wall cylinder of the sampling device, the sampling device 1 can expand and contract outward inside the outer wall cylinder 4 of the sampling device. When the outer sealing column 102 of the sampling device 1 extends outward, it is inserted into the material at this time, and the material enters between the two sealing columns 102. Then, by operating the main rod 9 of the sampling device, the sampling device 1 is pulled back into the outer wall cylinder 4 of the sampling device to achieve the purpose of sampling. After sampling, by first removing the main rod 10 of the outer wall cylinder of the sampling device and then removing the main rod 9 of the sampling device, the sampling device body forms a sealed container and can be directly sent to the laboratory for sampling.

[0031] Embodiment 2:

[0032] In this embodiment, on the basis of Embodiment 1, it is further limited that at least two sampling device sealing rings 2 are arranged on the outer circumferential surfaces of the two sealing columns 102.

[0033] The sealing column 102 seals the sampler 1 with the outer wall cylinder 4 of the sampler through the sampler sealing ring 2, and there are at least two sampler sealing rings 2 to improve the sealing effect.

[0034] Other parts of this embodiment are the same as those of the above-mentioned Embodiment 1 and will not be described in detail.

[0035] Embodiment 3:

[0036] In this embodiment, on the basis of Embodiment 1, it is further limited that one end of the main rod 9 of the sampler is provided with a main rod threaded end 901, and a connecting threaded end 103 is provided on the sealing column 102 close to the main rod 9 of the sampler. The main rod threaded end 901 and the connecting threaded end 103 are connected by a connecting nut 7.

[0037] The connecting nut 7 is used to realize the butt joint connection between the main rod 9 of the sampler and the sampler 1, and it is convenient for disassembly.

[0038] Other parts of this embodiment are the same as those of the above-mentioned Embodiment 1 and will not be described in detail.

[0039] Embodiment 4:

[0040] In this embodiment, on the basis of Embodiment 1, it is further limited that one end of the outer wall cylinder 4 of the sampler is provided with an outer wall cylinder threaded end 401, a limiting ring 5 is provided at one end of the main rod 10 of the outer wall cylinder of the sampler close to the outer wall cylinder 4 of the sampler, and an outer wall cylinder connecting nut 8 is sleeved on the side of the limiting ring 101 away from the outer wall cylinder 4 of the sampler. The outer wall cylinder 4 of the sampler is connected to the main rod 10 of the outer wall cylinder of the sampler through the connection of the outer wall cylinder connecting nut 8 and the outer wall cylinder threaded end 401.

[0041] The outer wall cylinder connecting nut 8 is used to realize the butt joint connection between the main rod 10 of the outer wall cylinder of the sampler and the outer wall cylinder 4 of the sampler, which is convenient for disassembly.

[0042] Other parts of this embodiment are the same as those of the above-mentioned Embodiment 1 and will not be described in detail.

[0043] Embodiment 5:

[0044] In this embodiment, on the basis of Embodiment 1, it is further limited that a groove 11 of the main rod of the outer wall cylinder of the sampler is provided at one end of the main rod 10 of the outer wall cylinder of the sampler away from the outer wall cylinder 4 of the sampler, and a positioning pin 13 of the main rod of the sampler is provided at the outer circle of one end of the main rod 9 of the sampler away from the sampler 1.

[0045] The positioning pin 13 of the sampler main rod can slide within the main rod groove 11 of the outer wall cylinder of the sampler. When the sampler main rod 9 moves into the main rod 10 of the outer wall cylinder of the sampler, the positioning pin 13 of the sampler main rod aligns with the main rod groove 11 of the outer wall cylinder of the sampler, causing the sampler main rod 9 to move in the radial direction of the main rod 10 of the outer wall cylinder of the sampler. When pulling out the sampler main rod 9, rotate the sampler main rod 9 to make the positioning pin 13 of the sampler main rod deviate from the entrance of the main rod groove 11 of the outer wall cylinder of the sampler, thus preventing the accidental radial movement of the sampler main rod 9.

[0046] The other parts of this embodiment are the same as those of the above-mentioned Embodiment 1 and will not be elaborated here.

[0047] Embodiment 6:

[0048] Based on Embodiment 1, this embodiment further defines that operating handles 12 are provided at one ends of the main rod 10 of the outer wall cylinder of the sampler and the sampler main rod 9 away from the sampler body.

[0049] The operating handle 12 improves the operating efficiency of the sampler main rod 9 and the main rod 10 of the outer wall cylinder of the sampler.

[0050] The other parts of this embodiment are the same as those of the above-mentioned Embodiment 1 and will not be elaborated here.

[0051] Embodiment 7:

[0052] Based on any one of Embodiments 1 to 6, this embodiment further defines that the outer end of the sealing column 102 on the side away from the sampler main rod 9 is one of a conical shape, a round head shape, or a flat head shape.

[0053] It is possible to select the shape of the outer end of the sealing column 102 according to the actual sampling scenario, improving the practicality.

[0054] The other parts of this embodiment are the same as those of any one of the above-mentioned Embodiments 1 to 6 and will not be elaborated here.

[0055] Embodiment 8:

[0056] Based on any one of Embodiments 1 to 6, this embodiment further defines that the shape of the outer wall cylinder 4 of the sampler is one of a cylindrical shape, a square shape, or a polygonal shape, and the outer shapes of the two sealing columns 102 match the outer wall cylinder 4 of the sampler.

[0057] It is possible to select the shape of the outer end of the outer wall cylinder 4 of the sampler according to the actual sampling scenario, improving the practicality.

[0058] The other parts of this embodiment are the same as those of any one of the above-mentioned Embodiments 1 to 6 and will not be elaborated here.

[0059] The working principle of the present utility model:

[0060] During normal use, first raise the outer wall cylinder 4 of the sampler to the operating handle 12 of the main rod 9 of the sampler through the operating handle 12 of the main rod 10 of the outer wall cylinder of the sampler, ensuring that the sealing column 102 of the sampler 1 (the sealing column 102 is conical) and the loading part (the loading part is the outer side of the connecting rod 101) are in the exposed state. Then insert the sampler 1 into the specified position in the middle of the silo. Press the operating handle 12 of the main rod 10 of the outer wall cylinder of the sampler to make the positioning pin 13 of the main rod of the sampler higher than the groove 11 of the main rod of the outer wall cylinder of the sampler. Rotate the operating handle 12 of the main rod 10 of the outer wall cylinder of the sampler so that the positioning pin 13 of the main rod of the sampler leaves the groove 11 of the main rod of the outer wall cylinder of the sampler to complete the positioning and prevent the outer wall cylinder 4 of the sampler from separating from the sampler 1 during the process of withdrawing the sampler. After sampling, withdraw the main body of the sampler. Since the sampler 1 and the outer wall cylinder 4 of the sampler are sealed to the main body of the sampler through the sampler sealing ring 2, the inside of the sampler is in a sealed state at this time. Loosen the outer wall cylinder connection nut 9, rotate the operating handle 12 of the main rod 10 of the outer wall cylinder of the sampler so that the positioning pin 13 of the main rod of the sampler enters the groove 11 of the main rod of the outer wall cylinder of the sampler, and retract the main rod 10 of the outer wall cylinder of the rotating sampler to the rear of the sampler to expose the sampler connection nut 7. Loosen the sampler connection nut 7, and the main body 1 of the sampler and the main rod 9 of the sampler are separated. The sealed container can be directly sent to the laboratory for sampling.

[0061] Finally, it should be pointed out that the above embodiments are only relatively representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments and can have many variations. Any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention shall be considered to fall within the protection scope of the present invention.
