[0003] The sampling environment of dry powder is relatively poor compared with coarse-grained material and wet powder. Because the particle size of the material is fine, the sampling space is filled with fine particle dust, which is easy to enter the body of the worker through respiration; in addition, it is difficult to see the cross section of the material with the eyes, which affects the accuracy of sampling.

[0004] Some powder processing units transport materials through belt conveyors. Because the transported material is much, the transmission speed of the belt conveyor is relatively fast, and when sampling at the material dropping point of the conveyor, the sampler is easy to fall off or collide with the belt conveyor, which not only increases the labor intensity of sampling, but also brings safety problems to the workers; some dry powder manufacturers use advanced pneumatic sampling devices from abroad to ensure the representativeness of the sample and the safety of the sampling personnel, but the investment cost is high.

[0005] In view of the existing problems of fine particle dry powder sampling, it is necessary to develop a sampling device to realize low-cost precise sampling and reduce the labor intensity of workers. CONTENT OF THE UTILITY MODEL

[0009] A controller is further included, and the controller is electrically connected with the speed regulating motor and the dustproof sliding table.

[0010] Further, the dustproof sliding table can reciprocate in the horizontal direction through the controller to drive the sampling pipe to intercept the material. Further, the dustproof sliding table can reciprocate in the horizontal direction through the controller to drive the sampling pipe to intercept the material.

[0011] The utility model discloses the beneficial effect lies in:

[0012] The utility model discloses can take out the representative fine particle dry powder, create the condition for subsequent detection and analysis, its upper part mainly is dry powder sampling pipe, and the lower part mainly is the dustproof slide platform of reciprocating motion, and the uniformity intercepts material flow, wherein, dry powder sampling pipe can force discharge dry powder through the discharge screw, guarantee the continuity and smooth of sampling, and, dustproof slide platform is suitable for the operation under the harsh environment of high dust content, drive sampling pipe reciprocating motion, create the condition for accurate, reliable intercept material, since the wet sampling of various trades is more common currently, and fine particle dry powder sampling device is relatively less, therefore, the utility model discloses novel and practical.
