Drawings

Fig. 1 is a schematic view of the overall structure of the present invention;

fig. 2 is a schematic diagram of the internal structure of the present invention.

In the figure: 1. the cleaning device comprises a square plate 2, a push-pull rod 3, a drawer 4, an outer pipe 5, a circular baffle 6, a cleaning rod 7, a first opening 8, a second opening 9, a circular plate 10, a stainless steel bar 11, a sponge pad 12 and a stopper.

Detailed Description

The structure and principle of such a device will be apparent to those skilled in the art from the following further description of the invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 and 2, the powder closed simple sampler comprises a push-pull piece, a cleaning rod, an outer tube and a drawer, wherein the drawer is a square tube, and the front end of the drawer is provided with an inclined surface for facilitating bag entering and sampling. The push-and-pull piece includes square board and push-and-pull rod, and the push-and-pull rod is connected perpendicularly in square board upper end edge to inside the drawer was located to the push-and-pull piece, square board can be through the push-and-pull of push-and-pull rod make seesaw along the inside of drawer, and square board can move outside to the drawer front side. When the square plate moves to the outside of the front side of the drawer, the push-pull rod can drive the square plate to rotate.

The drawer is arranged in the outer tube and can move back and forth along the inner part of the outer tube. Before the drawer gets into the powder bag, push away the square board outside the drawer, when the drawer got into the powder bag, because square board has blocked a large amount of powder, the powder can only follow the space between square board and the drawer front end, reduces in the powder gets into the drawer, is applicable to the powder sample that the required amount is few. In addition, rotatory square board can make the powder get into the drawer in, increases the acquisition volume of powder.

The sponge mat is arranged between the inner wall of the outer pipe and the outer wall of the drawer, the drawer after taking the materials can be wiped to clean the powder remained at the bottom when being drawn back by the design of the sponge mat, the powder remained in the outer pipe is reduced, and meanwhile, the next powder can be prevented from bringing cross contamination.

The inner wall of drawer has hung circular baffle, and the cleaning rod can follow the drawer and get into, with circular baffle jack-up, can clean the drawer, can avoid the cross contamination of many varieties sample, and is applicable to the sample of multiple powder.

The inner wall of the drawer is provided with a stopper which can limit the movement of the square plate and prevent the square plate from moving to the rear side of the drawer to be contacted with the circular baffle.

The outer tube lower part has been seted up first opening, and first opening inner wall is seted up there is the internal thread, and the external screw thread cooperation of first open-ended internal thread and sample bottle can be used to the installation sample bottle. The lower part of the drawer is provided with a second opening which is opposite to the first opening.

The inner edge of the second opening is hinged with a circular plate which can move downwards along the second opening to the first opening. The stainless steel bars can extend into the space between the inner wall of the lower end of the outer pipe and the outer wall of the lower end of the drawer and can support the circular plate. When the powder is required to be put into the sampling bottle, the stainless steel bars are drawn out, the circular plate falls into the sampling bottle, and the powder can enter the sampling bottle, so that the drifting pollution caused by sampling and transferring processes is avoided.

The drawer is connected with a drawer handle, the outer tube is connected with an outer tube handle, and the arrangement of the drawer handle and the outer tube handle facilitates the grasping of an operator.

The square plate, the push-pull rod and the circular baffle are made of stainless steel, so that resistance brought by sampling powder can be reduced, and cleanness of the sampler can be guaranteed.

The utility model discloses still have following operating method:

1. firstly, holding the sampler by hand, installing a sampling bottle at a first opening, opening an opening with the same size as an outer pipe opening at the bag opening of the powder bag, pushing a square plate to the outside of the front end of the drawer, holding the handle of the outer pipe by one hand, and holding the handle of the drawer by the other hand and pushing the drawer into the powder bag;

2. rotating the push-pull rod to drive the square plate to rotate by 180 degrees, pulling the square plate to push the powder into the drawer, simultaneously rotating the push-pull rod again to enable the square plate to rotate by 180 degrees and pull the square plate, repeating the operations for a plurality of times (determining the times according to the required amount of the powder), and when the required amount of the powder is met, holding the handle of the drawer by hands to draw the drawer back;

3. the stainless steel strip is drawn out, the push-pull rod is pulled back, the powder enters the sampling bottle through the second opening and the first opening in sequence, after a sufficient amount of sampling is carried out, the stainless steel strip is pushed in to seal the second opening of the drawer, the square plate is pushed out from the drawer, the cleaning bat is pushed in, and the powder is cleaned;

4. taking down the sampling bottle, covering the bottle cap and sealing, and then taking the next time;

5. after the final sampling is finished, the sampler can be uniformly and thoroughly cleaned after being disassembled, so that the phenomenon that the sampler is remained for a long time and cannot be cleaned is avoided.
