[0028] Reference below Figure 1-Figure 5 , the implementation of the powdered material bin proposed in an embodiment of the utility model is described in detail.

[0029] The powder material bin according to the embodiment of the utility model is installed on a bin loading device, and comprises: a bin body 1 and a scraping assembly 2.

[0030] Specifically, the silo body 1 has a first discharge channel 12 and a cavity 11 suitable for storing powder; the scraping assembly 2 has a spiral conveying shaft 21 and a scraping member 22, the spiral conveying shaft 21 is rotatably connected to the silo body 1 and the spiral conveying shaft 21 extends into the first discharge channel 12, and the scraping member 22 is connected to the spiral conveying shaft 21. When the spiral conveying shaft 21 rotates, the scraping member 22 rotates to scrape the powder, and the powder is discharged from the first discharge channel 12.

[0031] That is to say, the spiral conveying shaft 21 is connected to the scraper 22, which can drive the scraper 22 to rotate and scrape the material, thereby scraping and flattening the powder adhering to the inner wall of the cavity 11 and the powder accumulated in the cavity 11 and bringing it close to the spiral conveying shaft 21, and then the spiral conveying shaft 21 rotates itself to discharge the powder from the first discharge channel 12.

[0032] Thus, by storing powder in the silo body 1, the spiral conveying shaft 21 of the scraping assembly 2 cooperates with the scraping member 22 to scrape the powder while discharging it from the first discharge channel 12 of the silo body 1. The powder material silo can discharge powder with poor fluidity smoothly with high discharge accuracy.

[0033] For the installation of the screw conveying shaft 21, the scraping assembly 2 includes a first mounting plate 23 and a second mounting plate 24.

The first mounting plate 23 is connected to the second mounting plate 24, and the second mounting plate 24 is connected to the silo body 1. It can be understood that the installation of the screw conveying shaft 21 can be facilitated by the first mounting plate 23, and the connection of the screw conveying shaft 21 to the silo can be facilitated by the second mounting plate 24. At the same time, the processing difficulty of the first mounting plate 23 and the second mounting plate 24 can be reduced, which is conducive to cost saving. Among them, the first mounting plate 23 can be connected to the second mounting plate 24 by screws, and the second mounting plate 24 can be arranged to be connected with the silo body 1 in a groove.

[0034] As for the first mounting plate 23, the first mounting plate 23 has a through hole 231, and the through hole 231 extends into the cavity 11 to install the screw conveying shaft 21. It can be understood that the through hole 231 of the first mounting plate 23 and the extension of the through hole 231 into the cavity 11 can facilitate the installation of the screw conveying shaft 21, increase the contact and matching section between the through hole 231 and the screw conveying shaft 21, and thus improve the support strength of the screw conveying shaft 21. Among them, the screw conveying shaft 21 can be installed in the through hole 231 through a bearing, and the number of bearings can be two, and the two bearings are correspondingly installed at both ends of the through hole 231.

[0035] As for the scraper 22, the scraper 22 includes a plurality of scraper rods 221 and a connecting block 222, wherein the connecting block 222 is connected to the spiral conveying shaft 21, and the plurality of scraper rods 221 are connected to the connecting block 222 and are distributed on two opposite sides of the spiral conveying shaft 21. It can be understood that the connection block 222 is provided to facilitate the installation of the scraper rod 221, and the scraper rod 221 is provided to facilitate the scraper rod 221 to rotate and scrape the powder in the cavity 11, thereby preventing the powder from adhering to the inner wall of the cavity 11, and facilitating the smooth discharge of the powder. Among them, the connecting block 222 can be sleeved on the spiral conveying shaft 21, the number of the scraper rods 221 can be four, and two scraper rods 221 arranged in a gap are provided on each side of the spiral conveying shaft 21, and the scraper rods 221 can be square rods.

[0036] As for the scraper rod 221, both sides of the spiral conveying shaft 21 are provided with a scraper rod 221 in a vertical state and a scraper rod 221 in an inclined state. The scraper rod 221 in a vertical state is arranged away from the spiral conveying shaft 21, and the scraper rod 221 in an inclined state is arranged close to the spiral conveying shaft 21 and inclined toward the first discharge channel 12. It can be understood that the powder adhering to the inner wall of the cavity 11 can be scraped off by the scraper rod 221 in a vertical state, and the powder can be scraped toward the spiral conveying shaft 21 by the scraper rod 221 in an inclined state, and the spiral conveying shaft 21 discharges the powder in cooperation with the first discharge channel 12. Among them, the first discharge channel 12 and the spiral conveying shaft 21 can be clearance-fitted.

[0037] For driving the screw conveying shaft 21, the screw conveying shaft 21 is connected with a driven gear 25, and the driven gear 25 is suitable for driving the screw conveying shaft 21 to rotate. It can be understood that by setting the driven gear 25, it is convenient for the driven gear 25 to mesh with the driving gear of the external driving member, so that the driven gear 25 drives the screw conveying shaft 21 to rotate. Among them, the external driving device can position the silo body 1 through the positioning hole on the second mounting plate 24, so that the driven gear 25 and the driving gear are meshed.

[0038] As for the silo body 1, the silo body 1 includes a barrel 13 and a first cover 14, the first cover 14 is detachably connected to the barrel 13, and the first cover 14 is provided with a first discharge channel 12.

Among them, the first cover 14 and the barrel 13 can be connected by threads.

[0039] As for the silo body 1, the silo body 1 includes a second cover 15, the second cover 15 is connected to the first cover 14, and the second cover 15 is provided with a second discharge channel 16, the second discharge channel 16 is coaxially arranged with the first discharge channel 12, and the second discharge channel 16 is truncated. It can be understood that, since the caliber of the test tube is generally small, the powder discharged from the first discharge channel 12 can be collected in the second discharge channel 16 through the second cover 15, and then the truncated cone arrangement of the second discharge channel 16 makes the discharge port of the second discharge channel 16 smaller, so as to facilitate the addition of powder into the test tube.
