[0043] In this embodiment, the stirring member 12 includes a rotating shaft 121, a first stirring body 122 and a second stirring body 123. The top of the rotating shaft 121 is connected to the rotor end of the motor 11. The first stirring body 122 is arranged at the upper part of the rotating shaft 121, and the second stirring body 123 is arranged at the lower part of the rotating shaft 121. By arranging the first stirring body 122 and the second stirring body 123, the upper layer and the lower layer of the sample can be stirred at the same time, shortening the stirring time, and at the same time making the stirring more sufficient, thereby improving the representativeness of the mixed sample.

[0044] In this embodiment, the discharge valve 4 includes a cover body 41 and a fixing member 42. The side of the cover body 41 abuts against the opening of the discharge pipe 3, and the fixing member 42 is used to fix the cover body 41. The fixing member 42 and the cover body 41 cooperate to enable the cover body 41 to open and close the opening of the discharge pipe 3, so that customers can stir and remove the sample.

[0045] In this embodiment, the silo 1 includes a first cavity 15 and a second cavity 16, one end of the first cavity 15 is connected to the top of the second cavity 16, one end of the discharge pipe 3 is connected to the side of the second cavity 16, and one end of the sampling tube 2 is connected to the bottom of the second cavity 16.

[0046] Example 2

[0047] The difference between this embodiment and embodiment 1 is that a second handle 25 is provided on the side of the sampling tube 2, and the second handle 25 is used to move the sampling tube 2. The second handle 25 is used to move the sampling tube 2 during sampling, and cooperates with the first handle 132 to better insert the sampling tube 2 into the sample for sampling during sampling, and can also better fix the sampler during mixing, so that the motor 11 drives the stirring member 12 to mix and stir the sample.

[0048] In this embodiment, a first connector 17 is provided at one end of the silo 1 close to the sampling tube 2, and a second connector 26 is provided at one end of the sampling tube 2 close to the silo 1. The first connector 17 and the second connector 26 are detachably connected. By providing the first connector 17 and the second connector 26, the sampling tube 2 can be separated from the silo 1, which is convenient for users to select different sampling tubes 2 for different sampling environments. For example, the sampling tube 2 can be made of PTFE, which can effectively avoid the introduction of magnetic foreign matter.

[0049] In this embodiment, a limiter 27 is provided at one end of the sampling tube 2 close to the silo 1, and the limiter 27 is used to limit the connection length between the sampling tube 2 and the silo 1. The limiter 27 can prevent the sampling tube 2 from being excessively embedded in the silo 1, so that the first one-way valve 21 cannot be closed normally, causing the sample to flow from the silo 1 into the sampling tube 2, affecting the sampling effect, and also defines an optimal connection distance for the user, which is convenient for the user to install, so that the opening of the sampling tube 2 and the first one-way valve 21 are just matched, so that the first one-way valve 21 can work normally.

[0050] In this embodiment, the first one-way valve 21 includes a first fixed body 211, a cover plate 212 and a first connecting shaft 213. The cover plate 212 is rotatably connected to the first fixed body 211 through the first connecting shaft 213, and the side of the cover plate 212 abuts against the opening of the sampling tube 2. When the side of the cover plate 212 abuts against the opening of the sampling tube 2, the sample can be prevented from flowing from the silo 1 into the sampling tube 2. When the user turns the sampler upside down, the cover plate 212 will rotate through the first connecting shaft 213 due to the effect of gravity, and then open the opening of the sampling tube 2. When the user returns the sampler to the normal position, the cover plate 212 will rotate through the first connecting shaft 213, thereby sealing the opening of the sampling tube 2 and preventing the sample from flowing from the silo 1 into the sampling tube 2.

[0051] In this embodiment, the second connecting member 14 includes a connecting buckle 141, a second fixed body 142, a wrench 143 and a second connecting shaft 144. The side of the connecting buckle 141 is rotatably connected to the side of the wrench 143, and the wrench 143 is rotatably connected to the second fixed body 142 through the second connecting shaft 144. The first connecting member 131 is a hook structure, and the hook part of the hook structure cooperates with the connecting buckle 141 to fix the top cover 13 on the top of the silo 1. The wrench 143 is used for the customer to control the connecting buckle 141. The side of the connecting buckle 141 is provided with a connecting protrusion. The wrench 143 is a U-shaped structure, and the inner surface of the U-shaped structure is provided with a connecting groove, and the connecting protrusion is embedded in the connecting groove. When the user needs to open the top cover 13, he only needs to lift up the wrench 143, and the wrench 143 will drive the connecting buckle 141 to pull up, so that the first connecting member 131 can be removed from the connecting buckle 141; when the user needs to close the top cover 13, he only needs to hang the first connecting member 131 on the connecting buckle 141, and then pull down the wrench 143, and then the wrench 143 will drive the connecting buckle 141 to tighten the first connecting member 131 downward, thereby fixing the top cover 13 on the silo 1.

[0052] In this embodiment, the fixing member 42 includes a third fixing body 421, a lifting eye bolt 422 and a third connecting shaft 423, and the lifting eye bolt 422 is rotatably connected to the third fixing body 421 through the third connecting shaft 423. The lifting eye bolt 422 is used to fix the cover body 41. When the user needs to remove the cover body 41, the lifting eye bolt 422 needs to be loosened, and then the lifting eye bolt 422 can be rotated through the third connecting shaft 423 to remove the cover body 41 area, so that the cover body 41 can be removed, thereby facilitating the sample to flow out of the discharge pipe 3; when the user needs to install the cover body 41, the lifting eye bolt 422 only needs to be reset and then tightened to fix the cover body 41 to the opening of the discharge pipe 3.

[0053] In this embodiment, a groove 411 is provided on the edge of the cover body 41, and one end of the eye bolt 422 passes through the groove 411 and is rotatably connected to the third fixed body 421. By providing the groove 411, the eye bolt 422 can better fix the cover body 41, prevent the cover body 41 from moving left and right, and improve the sealing effect. The utility model has four fixing members 42, which are not specifically limited here. They are respectively arranged on the sides of the discharge pipe 3, and the distances between adjacent fixing members 42 are equal. There are also four grooves 411, which are matched with the four fixing members 42 respectively. This arrangement can prevent uneven fixing force of the cover body 41, so that the cover body 41 is more stably fixed at the opening of the discharge pipe 3, and improve the sealing effect.

[0054] The other structures of this embodiment are the same as those of Embodiment 1 and will not be described again here.

[0055] The samples taken by the utility model can reflect the material state of multiple layers of materials in a ton bag or a material box, and a batch of powder materials can be mechanically mixed after multi-point sampling, which can optimize the problem of poor sample representativeness, and has the characteristics of low cost, strong applicability, high work efficiency, etc. PTFE can be used in the material selection of the sample storage part 23 and the sampling head 24 to avoid the introduction of magnetic foreign matter; secondly, the multifunctional sampling head 24 can be replaced at the bottom opening of the sampling tube 2, and targeted selection can be made for materials with different fluidity, adhesion, etc.

[0056] In order to solve the problem that manual stirring is time-consuming and has poor mixing effect, resulting in the final sample being not representative, and the detection value of the sample being greatly different from the overall value, thus affecting the quality judgment, the utility model uses mechanical mixing to shorten the mixing time and improve the stirring effect.

[0057] After installing different sampling heads 24 according to the characteristics of the powder material, the sampler is inserted into the material in the ton bag or material box, the second one-way valve 22 is opened by the powder material, and the powder enters the sampling tube 2. When the sampler is lifted, the second one-way valve 22 is closed due to the gravity of the material. Then the sampler is turned 180°, and the powder material flows into the silo 1 due to gravity. Then, multiple-point sampling is repeated according to sampling needs. After each sampling, the sampler is turned over to allow the material to flow into the silo 1.

[0058] When sampling is completed, the sampler is turned over to make the silo 1 inverted, and the motor 11 is turned on for mechanical mixing, and the mixing time is determined according to needs. After the mixing is completed, the silo 1 is turned over again to return to the normal position, the discharge valve 4 on the discharge pipe 3 is opened, the sample bag mouth is covered with the discharge pipe 3, and the retained sample is transferred into the sample bag according to needs, and the sampling and mixing is completed.

[0059] The single-tube sampling is simpler and easier to clean than the sleeve sampler. The sampling tube 2 has no opening on the side to avoid material leakage and spillage. The sampling head 24 is detachable, and sampling heads 24 with different functions can be selected according to the characteristics of the powder. The motor 11 and the stirring member 12 are also added to make the sample more consistent and representative. The bottom of the silo 1 is provided with a discharge pipe 3, and the sample can flow directly into the sample bag through the discharge pipe 3, reducing the harm of dust to the human body during the sampling process.

[0060] Before use, first confirm that the selected outer circle inner square bevel sampling head or PTFE wire bevel sampling head is normally connected to the sample storage part 23 through the first connecting part 231 and the second connecting part 241, and then confirm whether the cover body 41 at the opening of the discharge pipe 3 is normally closed, whether the top cover 13 is normally closed through the first connecting part 131 and the second connecting part 14, and whether the first stirring body 122 and the second stirring body 123 are normally installed.

[0061] When in use, hold the second handle 25 and insert the sampling head 24 downward into the powder in the ton bag or material box to be sampled to the bottom. The powder enters from the center of the sampling head 24 to push open the second one-way valve 22 and enter the sample storage part 23. When the sampling at this point is completed, the sampler is pulled out. Due to the obstruction of the second one-way valve 22 inside the sampling head 24, the material above the second one-way valve 22 will stay in the sample storage part 23. The sampler is turned 180°. The powder pushes open the cover plate 212 of the first one-way valve 21 at the other end of the sample storage part 23 due to gravity, and the powder enters the silo 1. Then the sampler is turned 180° to push the sampling head 24. Facing downward, repeat the above steps as needed to perform multi-point sampling. After completing the sampling, turn the sampler over again. At this time, the material gathers in the first cavity 15. Turn on the motor 11 to drive the first stirring body 122 and the second stirring body 123 on the stirring member 12 to fully mix the powder in the silo 1. After the mixing is completed, turn the sampler over again to return the sampler to the right position. At this time, the material gathers in the second cavity 16. The second cavity 16 is conical to facilitate material collection. Unscrew the eye bolt 422 so that the cover 41 can be removed, cover the sampling bag mouth with the discharge pipe 3, and pour the retained sample into the sample bag as needed to complete the sampling and mixing.

[0062] The sampling head 24 of the utility model is connected to the sampling tube 2, and the sampling tube 2 is connected to the silo 1 through a threaded interface, and can be disassembled by rotation; the first cavity 15 and the top cover 13 are connected by a lock, which can be separated by opening the lock; the discharge pipe 3 on the second cavity 16 and the cover body 41 are connected by a lifting bolt 422, which can be separated by loosening the lifting bolt 422, and it is easy to disassemble when cleaning is required.
