[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 This embodiment provides a quantitative sampling device for soluble powder production, including a sampling chamber 1 for sampling the soluble powder. A sealing component for sealing the open end of the sampling chamber 1 is provided on the outside of the sampling chamber 1. The sampling chamber 1 is inserted into the interior of the soluble powder, and the soluble powder enters the interior through the inlet end of the sampling chamber 1.

[0023] The sealing assembly includes a sealing plate 2 and a push plate 3. A movable track 4 is fixedly installed on the top of the sampling chamber 1. A first slide 12 is slidably installed on one end of the movable track 4, and a second slide 15 is slidably installed on the other end of the movable track 4. The first slide 12 is located above the second slide 15, wherein the movable track 4 can limit the moving trajectories of the first slide 12 and the second slide 15, preventing the first slide 12 and the second slide 15 from shaking and deflecting when moving, thereby improving the stability of the movement of the first slide 12 and the second slide 15.

[0024] The first slide 12 and the second slide 15 are extended to one end outside the movable track 4 and are fixedly installed with a push plate 3. The open end of the sampling chamber 1 is symmetrically slidably installed with a sealing plate 2 that seals its own open end. The other ends of the two push plates 3 are fixedly connected to the outer walls of the two sealing plates 2 respectively. The outside of the movable track 4 is provided with a driving assembly for moving the first slide 12 and the second slide 15. When the sampling chamber 1 is inserted into the soluble powder, the first slide 12 and the second slide 15 are pushed at the same time to move them away from each other. At this time, the two sealing plates 2 move synchronously with the two push plates 3, so that the soluble powder around the sampling chamber 1 can enter its interior, which is conducive to stratified sampling of the accumulated soluble powder and reduces the error caused by the soluble powder detection results.

[0025] A U-shaped frame 5 is fixedly installed on the top of the sampling chamber 1, and a push rod 7 is fixedly installed on one end of the U-shaped frame 5 away from the top of the sampling chamber 1. The sampling chamber 1 is inserted into the interior of the soluble powder by holding the push rod 7, which is conducive to sampling the soluble powder in the sampling chamber 1.

[0026] The push rod 7 is slidably sleeved on one end of the push rod 7 away from the U-shaped frame 5, and the slide 8 is slidably sleeved on the outer wall of the slide 8. A through hole connected to its own inner cavity is provided, and a positioning pin 9 is slidably installed in the inner cavity of the through hole. The outer wall of the push rod 7 is provided with a plug-in groove 6 adapted to the positioning pin 9, wherein the push rod 7 is slidably sleeved in the inner cavity of the slide 8, and the distance between the sampling chamber 1 and the top of the slide 8 can be controlled by pushing and pulling the push rod 7, which is conducive to controlling the depth of the sampling chamber 1 inserted into the interior of the soluble powder, and when the middle of the open end of the through hole and the middle of the open end of the plug-in groove 6 are on the same horizontal line, the positioning pin 9 is inserted into the interior of the plug-in groove 6 through the through hole to realize the positioning of the push rod 7 after movement.

[0027] The ends of the two sealing plates 2 away from the sampling chamber 1 are both configured as conical structures, which is beneficial to reducing the resistance encountered when the sampling chamber 1 is inserted into the soluble powder, thereby improving the smoothness of the insertion of the sampling chamber 1 into the soluble powder.

[0028] The radius of one end of the sealing plate 2 close to the sampling chamber 1 is not less than the diameter of the opening end of the sampling chamber 1. When the adjacent sides of the two sealing plates 2 are fitted together, a complete cone can be formed, and the diameter of the large end of the cone is larger than the diameter of the opening end of the sampling chamber 1, which effectively prevents the soluble powder from entering the interior of the sampling chamber 1 when the sampling chamber 1 samples deep-seated soluble powder before reaching the sampling site.

[0029] A baffle 10 is fixedly installed in the inner cavity of the sampling chamber 1, and a spiral transmission roller 11 is rotatably installed at one end of the baffle 10 close to the open end of the sampling chamber 1, and a driving motor is fixedly installed at the other end of the baffle 10. A through hole connected to the other end of the baffle 10 close to the driving motor is opened, and the power output end of the driving motor passes through the through hole and is fixedly connected to one end of the spiral transmission roller 11. When the sampling chamber 1 reaches the sampling position, the two sealing plates 2 are separated from each other, and then the driving motor is started to allow the spiral transmission roller 11 to rotate with the power output end of the driving motor, thereby quickly transporting the soluble powder to the interior of the sampling chamber 1 to prevent the open end of the sampling chamber 1 from being blocked by the soluble powder.

[0030] Furthermore, the baffle 10 can support and protect the driving motor, preventing the soluble powder from entering the interior of the sampling chamber 1 and causing a large amount of soluble powder to adhere to the exterior thereof and cause damage.

[0031] A driving gear 13 is rotatably installed in the inner cavity of the movable track 4. The driving gear 13 is located between the first slide 12 and the second slide 15. A latch 14 that matches the driving gear 13 is fixedly installed on the adjacent side of the first slide 12 and the second slide 15. A transmission motor for driving the gear 13 is fixedly installed on the outer wall of the movable track 4. When the transmission motor is started, the driving gear 13 rotates accordingly. Under the action of the latch 14, the first slide 12 and the second slide 15 can slide synchronously and reciprocatingly, which is conducive to controlling the distance between the two sealing plates 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
