[0024] To make the purpose, technical solutions and advantages of the present invention clearer, the following will further describe the embodiments of the present invention in detail with reference to the drawings.

[0025] Figure 1 is a schematic diagram of the overall structure provided by an embodiment of the present utility model; Figure 2 is a schematic diagram of the overall structure from another angle provided by an embodiment of the present utility model; Figure 3 is a schematic diagram of the structure when the scraping blade and the sampling groove perform a scraping operation provided by an embodiment of the present utility model; Figure 4 is a schematic diagram of the structure when the scraping blade is accommodated on the sampling spoon provided by an embodiment of the present utility model. As Figures 1 to 4 shown, a measuring cylinder sampling tool includes: a sampling spoon 1 and a scraping blade 2. The sampling spoon 1 includes a sampling groove 11 and a handle 12. The sampling groove 11 and the handle 12 are strip-shaped structures. The handle 12 is arranged at one end of the sampling groove 11 along the length direction. The other end of the sampling groove 11 is an open structure. The scraping blade 2 has a scraping surface 21 matching the sampling groove 11 in the thickness direction.

[0026] Exemplarily, in an embodiment of the present utility model, the sampling groove 11 is 150 mm long and the handle 12 is 100 mm long. The operator holds the sampling spoon 1 through the handle 12, scoops up the sample powder from the sample powder storage place with the sampling groove 11, and then scrapes off the piled-up sample powder on the sampling groove 11 through the scraping surface 21 of the scraping blade 2 to prevent the piled-up sample powder from spilling during the movement of the sampling spoon 1. Then, the measuring cylinder is horizontally set, the sampling spoon 1 is horizontally inserted into the measuring cylinder, and the measuring cylinder is slowly erected to avoid powder splashing and dust generation, so that the sample powder smoothly falls into the measuring cylinder. Compared with the long-handled medicine spoon in the traditional technology, the sampling groove 11 in the embodiment of the present utility model is a strip-shaped groove structure, which can hold a larger volume of sample powder at one time, reduces the number of sampling operations, simplifies the sampling operation process, improves the sampling efficiency, and at the same time uses the scraping blade 2 to scrape off the piled-up sample powder in the sampling groove 11, which can prevent the sample powder from spilling during the movement of the sampling spoon 1 filled with the sample powder, thus solving the problem of easy powder spilling and dust pollution in the prior art.

[0027] A measuring cylinder sampling tool provided by an embodiment of the present utility model can operate the sampling groove 11 to sample a relatively large amount of sample powder at one time by setting the strip-shaped sampling groove 11, and then uses the scraping surface 21 of the scraping blade 2 to scrape off the excess sample powder in the sampling groove 11 and send it into the measuring cylinder. At the same time, the strip-shaped sampling groove 11 is also adapted to the measuring cylinder. The measuring cylinder can be horizontally set. By holding the handle 12 and completely inserting the sampling groove 11 into the measuring cylinder, and then erecting the measuring cylinder, the sample powder can be completely filled into the measuring cylinder, so that the sample powder will not spill outside the measuring cylinder, effectively solving the problems of low sampling efficiency and easy powder spilling and dust pollution in the prior art.

[0028] Optionally, scraping surfaces 21 are provided on both sides of the scraping blade 2 along the width direction.

[0029] Exemplarily, in the embodiment of the present utility model, scraping surfaces 21 are provided on both sides of the scraping blade 2. When an operator performs the operation of scraping off excess sample powder, either one of the scraping surfaces 21 can be arbitrarily selected for scraping operation, thereby improving the convenience of the operator's operation. When one of the scraping surfaces 21 is damaged, the other scraping surface 21 can also be selected for scraping operation, thereby improving the operation convenience of this measuring cylinder sampling tool.

[0030] Optionally, the scraping surface 21 is an arc surface.

[0031] Exemplarily, in the embodiment of the present utility model, compared with setting the scraping surface 21 as a flat surface, when the scraping surface 21 performs a scraping operation on the sampling slot 11, an arc-shaped powder stack is formed above the sampling slot 11, and more samples can be obtained in one sampling, thereby further improving the sampling efficiency of this measuring cylinder sampling tool.

[0032] Optionally, scale lines 111 are provided on the sampling slot 11 along the length direction.

[0033] Exemplarily, in the embodiment of the present utility model, scale lines 111 are engraved on the back of the sampling slot 11 along the length direction. One scale line 111 is set every 5 ml, and they are evenly spaced. The maximum range is 25 ml. By setting the scale lines 111, the operator can judge the quantity of the sample powder taken each time. Usually, a 50 g sample powder is required for one tap density test. By taking out about 25 ml of sample powder into the measuring cylinder each time, weighing the measuring cylinder, and then adjusting the corresponding weight, basically 1 - 2 sampling operations can meet the sampling requirement of 50 g. Compared with the traditional method of using a long-handled medicine spoon for sampling 15 - 20 times, the repeated operation is greatly reduced. By setting the scale lines 111, the operator can clearly know the volume of the sample powder taken each time, thereby further improving the operation convenience of this measuring cylinder sampling tool.

[0034] Optionally, the sampling slot 11 is a semi-circular slot.

[0035] Exemplarily, in the embodiment of the present utility model, setting the sampling slot 11 as a semi-circular slot can make the sampling slot 11 adapt to the shape of the measuring cylinder. The measuring cylinder is usually cylindrical. By setting the sampling slot 11 as a semi-circular slot, when the sampling slot 11 extends into the measuring cylinder and pours the sample powder, it can prevent the sampling slot 11 from colliding with the inner wall of the measuring cylinder, thereby reducing the risk of instrument damage and improving the practicality of this measuring cylinder sampling tool.

[0036] Optionally, a first protrusion 22 is provided on the scraping blade 2 along the thickness direction, and a first groove 121 matching the first protrusion 22 is provided on the handle 12.

[0037] Exemplarily, in the embodiment of the present utility model, as Figure 4 shown, by providing the first protrusion 22 and the first groove 121, when the measuring cylinder sampling tool of the present utility model is not in use, the scraping blade 2 can be mounted on the handle 12 for storage, and the scraping blade 2 and the sampling spoon 1 can be stored together, preventing the scraping blade 2 from being lost due to its small volume, thereby further improving the usability of the measuring cylinder sampling tool of the present utility model. In this embodiment, the handle 12 has a first side surface 13 matching the scraping blade 2, and the first side surface 13 is a plane, such that after the scraping blade 2 is mounted on the handle 12, it can fit with the handle 12 to form an integral body, making the combination of the handle 12 and the scraping blade 2 more compact.

[0038] Optionally, a plurality of first protrusions 22 are provided, and the plurality of first protrusions 22 are arranged at intervals along the length direction of the scraping blade 2.

[0039] Exemplarily, in the embodiment of the present utility model, a plurality of first protrusions 22 are provided on the scraping blade 2, and a plurality of first grooves 121 matching the first protrusions 22 are provided on the corresponding first side surface 13, which can enable the scraping blade 2 to be fixed on the handle 12 through the plurality of first protrusions 22, so that the scraping blade 2 is more stably arranged on the handle 12, thereby further preventing the scraping blade 2 from being lost.

[0040] Optionally, a second protrusion 23 is provided at one end of the scraping blade 2 along the length direction, and a second groove 122 matching the second protrusion 23 is provided at the end of the handle 12.

[0041] Exemplarily, in the embodiment of the present utility model, a second groove 122 is provided at the end of the handle 12 near the sampling groove 11, the notch direction of the second groove 122 is parallel to the first side surface 13, a second protrusion 23 is provided at one end of the scraping blade 2, the scraping blade 2 can be arranged parallel to the first side surface 13, and the second protrusion 23 is moved towards the direction of the second groove 122, such that after the second protrusion 23 is inserted into the second groove 122, the first protrusion 22 and the first groove 121 are then cooperated, so that the scraping blade 2 is fixed on the handle 12. By providing the second protrusion 23 and the second groove 122, the scraping blade 2 can be more stably arranged on the handle 12, thereby further preventing the scraping blade 2 from being lost.
