The first lifting component 1012 is arranged on the mounting base 1011, one end of the scraper bracket 1013 is arranged on the first lifting component 1012, and the scraper 1014 is arranged on the other end of the scraper bracket 1013. The first lifting component 1012 is used to drive the scraper 1014 to rise and fall in the medicine bin 4, and the scraper 1014 extends into the medicine bin 4 to fill the medicine powder into the pit 401 at the bottom of the medicine bin 4 when the medicine bin 4 rotates.

[0034] Specifically, the scraper 1014 extends into the medicine bin 4. When the medicine bin 4 rotates, the scraper 1014 moves down to the bottom of the medicine bin 4 to scrape the powder in the medicine bin 4 into the pit 401 to fill the pit 401 and realize the quantitative amount of the powder in the pit 401.

[0040] Specifically, when the medicine bin rotating sub-mechanism 103 rotates horizontally and reciprocates, the temporary storage position and the working position of the medicine bin 4 are rotated 180° to interchange. In order to facilitate the installation and positioning of the medicine bin 4, the limiting protrusions on the outer periphery of the medicine bin 4 are coaxial or perpendicular to the radial direction of some of the pits 401 in the medicine bin 4, and the protruding direction of the limiting protrusions is also in the same direction as the axial direction of the linear displacement sub-mechanism 104, so as to facilitate the movement and determination of the position of the pit 401.

The flexible push rod 2026 is installed and positioned through the hole reserved at the lower end of the spring seat 2024. The lower end of the flexible push rod 2026 needs to pass through the compression spring 2025 and be inserted into the powder tube 2021 to be responsible for pushing out the powder taken from the powder tube 2021.

[0052] When the powder insertion sub-mechanism 202 moves to one side of the ∩-shaped track, the powder is inserted and taken out, and when the powder insertion sub-mechanism 202 moves to the other side of the ∩-shaped track, the powder is filled into the tube shell. Below one side of the ∩-shaped track is the working position of the medicine bin 4, and below the other side of the ∩-shaped track is the injection position of the powder. The working position is located in the middle position, and the temporary storage position of the medicine bin on the other side of the interval from the working position. When the powder insertion tube 2021 descends, it is inserted into the pit 401 to extract the powder, and the second lifting component 2023 is used to drive the flexible push rod 2026 to move downward to push out the powder in the powder insertion tube 2021.

[0053] Furthermore, the rotating assembly 1021 is a rotating cylinder or an electric rotating displacement platform, and the first lifting assembly 1012 and the second lifting assembly 2023 are both telescopic cylinders or electric telescopic rods.

[0054] Further, the powder weighing mechanism 3 is used to weigh the powder injected into the tube shell, and the powder weighing mechanism 3 includes a mass meter 302 and a weighing seat 301. The weighing seat 301 is fixed on the mounting base 5, and the mass meter 302 is arranged on the weighing seat 302, and the mass meter 302 can display the weight of the loaded powder.

[0055] The utility model provides a device for taking and transporting powder for explosives, which can control the opening or closing of a linear motor module, a rotary motor, a drive motor, a rotary assembly, a first telescopic assembly, and a second telescopic assembly through a PLC controller. When in use, a medicine bin 4 filled with powder is placed in a temporary storage position of the medicine bin by other mechanisms or manually. After confirming that it is in place, the rotary assembly 1021 of the rotary position changing sub-mechanism 102 rotates 180° to shift the medicine bin 4 from the temporary storage position to the working position. The scraper 1014 of the scraper lifting sub-mechanism 101 descends to contact the bottom of the medicine bin 4. After the position of the scraper 1014 is fixed, the rotary motor 1031 of the medicine bin rotating sub-mechanism 103 rotates to drive the medicine bin 4 to rotate. The scraper 1014 sweeps the powder in the medicine bin 4 flat. After the rotation of the medicine bin 4 stops, The powder insertion sub-mechanism 202 moves to the medicine taking position under the drive of the reciprocating sub-mechanism 201, and the powder insertion tube 2021 inserts the powder in the medicine bin pit 401. After the insertion is completed, the reciprocating sub-mechanism 201 drives the powder insertion tube 2021 of the powder insertion sub-mechanism 202 to move to the injection position, and the flexible push rod 2026 of the powder insertion sub-mechanism 202 pushes the powder from the powder insertion tube 2021 into the injection tube shell, which is pre-placed on the powder weighing mechanism 3, and the powder weighing mechanism 3 can weigh the injected powder. According to the weighing result of the powder, the position of the pit 401 of the medicine taking position can be fine-tuned by adjusting the linear displacement sub-mechanism 104 to ensure that the quality of the powder in the inserted pit 401 is within the specified range.
