[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] like Figure 1As shown, in at least one embodiment, a material powder sampling and detection device is provided, comprising: an inner sleeve structure, a receiving sleeve 2 and a sampling mechanism; the receiving sleeve 2 is sleeved outside the inner sleeve structure; the sampling mechanism is inserted into the inner sleeve structure, the side wall of the receiving sleeve 2 is a hollow structure, a first notch 21 is provided on the inner wall of the receiving sleeve 2, and the first notch 21 is connected to the hollow part of the side wall; a gap is provided in the inner sleeve structure, and the gap corresponds to the first notch 21; the sampling mechanism is suitable for collecting the sample after passing through the gap and the first notch 21 and entering the hollow part of the receiving sleeve 2; the sampling of powder material is realized, and the conical protrusion 51 in the sampling mechanism is used to prevent the powder from accumulating and blocking the first notch 21 of the receiving sleeve 2 during the sampling process, thereby ensuring the sampling of powder material.

[0060] The first notch 21 on the receiving sleeve 2 serves as a feed port of the receiving sleeve 2 , and the powder material transported by the sampling mechanism is stored in the receiving sleeve 2 , thereby completing the sampling of the powder material.

[0061] like Figure 2 As shown, the inner sleeve mechanism comprises: an upper sleeve 1 and a lower sleeve 11; the upper sleeve 1 is arranged above the lower sleeve 11; there is a gap between the bottom surface of the upper sleeve 1 and the top surface of the lower sleeve 11; the receiving sleeve 2 is sleeved outside the upper sleeve 1 and the lower sleeve 11; the bottom surface of the lower sleeve 11 is lower than the bottom surface of the receiving sleeve 2; the upper sleeve 1 is threadedly connected to the inner wall of the receiving sleeve 2; an annular groove (not shown in the figure) is provided on the outer wall of the upper sleeve 1, and the annular groove is arranged close to the top surface of the upper sleeve 1; a fixing column 12 is provided in the annular groove, and the fixing column The length direction of 12 is parallel to the radial direction of the upper sleeve 1; one end of the fixed column 12 is located in the annular groove, and the other end is fixed. For example, when the material powder sampling and detection device is installed in a large mixing equipment, the other end of the fixed column 12 can be fixed on the inner wall of the mixing barrel. At this time, the fixed column 12 will not affect the rotation of the upper sleeve 1, but the fixed column 12 will prevent the upper sleeve 1 from rising and falling, and at this time, the receiving sleeve 2 can be slidably set on the inner wall of the mixing barrel, so that the receiving sleeve 2 can be raised and lowered but cannot rotate, and the lower sleeve 11 can be fixed on the inner wall of the mixing barrel, and the upper sleeve 1 and the lower sleeve 11 are separately set.

[0062] The fixing column 12 is slidably connected with the annular groove; since the upper sleeve 1 and the receiving sleeve 2 are threadedly connected, when the upper sleeve 1 starts to rotate, since the receiving sleeve 2 cannot rotate, relative movement occurs between the receiving sleeve 2 and the upper sleeve 1, that is, vertical movement occurs between the receiving sleeve 2 and the upper sleeve 1. Since the mixing barrel of large-scale mixing equipment is large in size, when the material powder sampling and detection device is installed near the bottom of the mixing barrel, it is difficult to take out the sampled powder after the traditional powder material sampling is completed due to the depth of the mixing barrel. At this time, the receiving sleeve 2 can be raised by rotating the upper sleeve 1, so that the receiving sleeve 2 moves upward close to the top of the mixing barrel, which is convenient for taking out the sampled material.

[0063] The bottom surface of the upper sleeve 1 is lower than the top surface of the first notch 21 opened on the receiving sleeve 2; the top surface of the lower sleeve 11 is lower than the top surface of the first notch 21 opened on the receiving sleeve 2; in the initial state, the upper sleeve 1 and the lower sleeve 11 will partially block the first notch 21. If powder material accumulates at the first notch 21, the receiving sleeve 2 can be raised and lowered to increase the part of the first notch 21 that is opened, so that the accumulated powder material can fall into the receiving sleeve 2 more conveniently, thereby avoiding the accumulation of powder material blocking the first notch 21.

[0064] like Figure 3 As shown, a second notch 22 is opened on the side wall of the receiving sleeve 2, and the second notch 22 is vertically arranged; the second notch 22 corresponds to the fixing column 12; the top of the second notch 22 is located on the top surface of the receiving sleeve 2; when the receiving sleeve 2 rises, the fixing column 12 will enter the second notch 22, and the second notch 22 can facilitate the lifting and lowering of the receiving sleeve 2, avoiding the side wall of the receiving sleeve 2 from hindering the lifting and lowering of the receiving sleeve 2.

[0065] The sampling mechanism includes: a driving shaft 3 and a spiral blade 31; the driving shaft 3 is inserted into the upper sleeve 1 and the lower sleeve 11; the spiral blade 31 is arranged on the driving shaft 3; the bottom end of the driving shaft 3 extends out from the opening on the bottom surface of the lower sleeve 11; the driving shaft 3 can be driven by a driving motor to rotate the spiral blade 31, and the rotating spiral blade 31 can transport the powder material to the first notch 21, and the powder material is received by the receiving sleeve 2 to complete the sampling of the powder material.

[0066] like Figure 4As shown, a turntable 4 is provided on the driving shaft 3, and a protrusion 41 is provided on the bottom surface of the turntable 4; the turntable 4 rotates with the driving shaft 3; a lifting plate 5 is provided in the upper sleeve 1, and the side wall of the lifting plate 5 contacts the inner wall of the upper sleeve 1; the lifting plate 5 is slidably connected with the inner wall of the upper sleeve 1; the lifting plate 5 is sleeved on the driving shaft 3, and the lifting plate 5 is located below the turntable 4; a plurality of conical protrusions 51 are provided on the bottom surface of the lifting plate 5; a plurality of blocks 52 are provided on the top surface of the lifting plate 5; The blocks 52 are arranged equidistantly along the circumference of the lifting plate 5; the top surface of the blocks 52 is an inclined surface; the blocks 52 are located below the protrusions 41, and the bottom surface of the protrusions 41 contacts the top surface of the blocks 52; the lifting plate 5 and the inner wall of the upper sleeve 1 can be connected by a spring to facilitate the resetting of the lifting plate 5. For example, a groove can be provided on the inner wall of the upper sleeve 1, and a plate can be provided on the side wall of the lifting plate 5 to extend into the groove. A spring is connected between the plate and the groove, and the lifting plate 5 can be reset after descending through the spring; when the drive shaft 3 rotates, the turntable is driven 4 rotates, the protrusion 41 rotates with the turntable 4, the protrusion 41 contacts the inclined surface of the block 52, so that the protrusion 41 can press the lifting plate 5 to move downward, and after the lifting plate 5 descends, the tip of the conical protrusion 51 will be lower than the bottom surface of the upper sleeve 1 and the top surface of the first notch 21, so that the tip of the conical protrusion 51 contacts the material transported up by the spiral blade 31, and the accumulated powder material is broken up, so that the powder material can enter the receiving sleeve 2; if the powder material accumulates between the upper sleeve 1 and the lower sleeve 11 and cannot enter the first notch 21, at this time, the conical protrusion 51 is inserted into the accumulation sleeve 2. The accumulated materials are blocked by the materials, causing the lifting plate to be unable to continue to descend, and the protrusion 41 cannot continue to move on the inclined plane. Since the driving shaft 3 is still rotating, the protrusion 41 will drive the lifting plate 5 to start rotating, causing the upper sleeve 1 to start rotating, and the rotation of the upper sleeve 1 will cause the receiving sleeve 2 to start descending. At this time, the bottom surface of the first notch 21 will gradually descend to be flush with the top surface of the lower sleeve 11, and the top surface of the first notch 21 will gradually descend to be flush with the bottom surface of the upper sleeve 1, so that the first notch 21 is completely opened, so that the accumulated powder material can enter the receiving sleeve 2.

[0067] The tip of the conical protrusion 51 faces downward, so that the powder material can be broken up by the tip of the conical protrusion 51 .

[0068] The top surface of the receiving sleeve 2 is open. When taking materials, the opening of the receiving sleeve 2 can be blocked by a cover, and the top of the second notch 22 is blocked by the fixed column 12. An accordion plate can be provided in the second notch 22 to prevent materials from entering the receiving sleeve 2 through the second notch 22 and the top surface opening of the receiving sleeve 2, and the accordion plate will not hinder the fixed column 12 from entering the second notch 22, and will not hinder the lifting and lowering of the receiving sleeve 2.

[0069] The material powder sampling and detection device is installed in the device that needs to take materials. In the initial state, the upper sleeve 1 and the lower sleeve 11 will partially block the first notch 21. When the driving shaft 3 rotates, the turntable 4 is driven to rotate (counterclockwise), and the protrusion 41 rotates with the turntable 4. The protrusion 41 contacts the inclined surface of the block 52, so that the protrusion 41 can press the lifting plate 5 to move downward. After the lifting plate 5 descends, the tip of the conical protrusion 51 will be lower than the bottom surface of the upper sleeve 1 and the top surface of the first notch 21, so that the tip of the conical protrusion 51 contacts the material transported by the spiral blade 31, and the accumulated powder material is broken, so that the powder material can enter the receiving sleeve 2; if the powder material accumulates between the upper sleeve 1 and the lower sleeve 11 and cannot enter the first notch 21, at this time, the conical protrusion 51 is blocked by the accumulated material after being inserted into the accumulated material, resulting in the inability of the lifting plate to continue to descend, and the protrusion 41 cannot continue to move on the inclined surface. The shaft 3 continues to rotate, and the protrusion 41 will drive the lifting plate 5 to start rotating, so that the upper sleeve 1 starts to rotate, and the rotation of the upper sleeve 1 will cause the receiving sleeve 2 to start descending. At this time, the bottom surface of the first notch 21 will gradually descend to be flush with the top surface of the lower sleeve 11, and the top surface of the first notch 21 will gradually descend to be flush with the bottom surface of the upper sleeve 1, so that the first notch 21 is completely opened, so that the accumulated powder material can enter the receiving sleeve 2; after the material sampling is completed, the driving shaft 3 drives the turntable 4 to rotate in the opposite direction (clockwise rotation), at this time the protrusion 41 will contact the side wall of the block 52, and the protrusion 41 drives the lifting plate 5 to rotate so that the upper sleeve 1 rotates, and the receiving sleeve 2 moves upward, driving the material to approach the top of the sampling device, so as to facilitate the material in the receiving sleeve 2 to be taken out; the method of taking out can be to open the cover and then take out the material in the receiving sleeve 2 through other devices, such as sucking out the material through negative pressure.

[0070] In at least one other embodiment, a working method using the above-mentioned material powder sampling and detection device is also provided, including: the sampling mechanism collects the sample through the gap and the first notch 21 and then enters the hollow part of the receiving sleeve 2.

[0071] In summary, through the inner sleeve structure, the receiving sleeve 2 and the sampling mechanism; the receiving sleeve 2 is sleeved outside the inner sleeve structure; the sampling mechanism is inserted into the inner sleeve structure, the side wall of the receiving sleeve 2 is a hollow structure, and a first notch 21 is opened on the inner wall of the receiving sleeve 2, and the first notch 21 is connected with the hollow part of the side wall; a gap is provided in the inner sleeve structure, and the gap corresponds to the first notch 21; the sampling mechanism is suitable for collecting the sample after passing through the gap and the first notch 21 and entering the hollow part of the receiving sleeve 2; the sampling of powder materials is realized, and the conical protrusion 51 in the sampling mechanism is used to prevent the powder from accumulating and blocking the first notch 21 of the receiving sleeve 2 during the sampling process, thereby ensuring the sampling of powder materials.
