Embodiment

Legs 2 are fixed to the bottom side of the cylinder body 1, and anti-slip blocks 3 are fixed to the bottoms of the legs 2. A feeding pipe 4 is provided at the feeding port on the upper side of the cylinder body 1, and a discharging pipe 6 is provided at the discharging port on the bottom side of the cylinder body 1; the feeding mechanism 5 includes a rotating shaft 51, a rotating cylinder 52, a spiral blade 53 and a servo motor 54. The upper side of the inner cavity of the cylinder body 1 is rotatably connected with the rotating shaft 51, and the bottom end of the rotating shaft 51 extends into the inner cavity of the discharging pipe 6. The rotating cylinder 52 is sleeved on the side surface of the rotating shaft 51. The bottom end of the rotating cylinder 52 is a conical platform structure that gradually shrinks from top to bottom. A spiral blade 53 is provided on the outer side of the rotating cylinder 52 and is located in the inner cavities of the cylinder body 1 and the discharging pipe 6. The spiral blade 53 is an integral structure. A servo motor 54 connected to the rotating shaft 51 is installed on the upper side of the cylinder body 1. By arranging the rotating cylinder 52 in the feeding mechanism 5, and the bottom end of the rotating cylinder 52 is a conical platform structure that gradually shrinks from top to bottom, and an integral spiral blade 53 is provided on the outer side of the rotating cylinder 52, and the spiral blade 53 is located in the inner cavities of the cylinder body 1 and the discharging pipe 6. As the rotating cylinder 52 rotates, the silicon powder can be conveyed from the bottom of the cylinder body 1 to the inside of the discharging pipe 6 and discharged through the spiral blade 53, avoiding the phenomenon that the silicon powder at the bottom of the cylinder body 1 is not cleaned properly, ensuring the feeding effect, with a simple overall structure and low production cost.

[0015] A scraping plate 7 is provided on the outer side of the spiral blade 53. The scraping plate 7 is in a spiral structure and is slidably connected to the inner walls of the cylinder body 1 and the discharging pipe 6 in a matching manner. When the spiral blade 53 rotates during the silicon powder feeding process, the scraping plate 7 is driven to rotate. The scraping plate 7 can scrape the materials on the inner walls of the cylinder body 1 and the discharging pipe 6, further ensuring the feeding effect.

[0016] Working principle: The crushed silicon powder enters the cylinder through the feed pipe 4. When it is necessary to discharge the silicon powder, the servo motor 54 drives the rotating cylinder 52 to rotate through the rotating shaft, thereby driving the spiral blade 53 to rotate. By the rotation of the spiral blade 53, the silicon powder can be conveyed from the bottom of the cylinder 1 into the discharge pipe 6 and discharged. Since the bottom end of the rotating cylinder 52 is a conical platform structure that gradually narrows from top to bottom, and the spiral blade 53 is an integral structure, it can better adapt to the structure composed of the cylinder 1 and the discharge pipe 6, avoiding the phenomenon that the silicon powder at the bottom of the cylinder 1 cannot be cleaned thoroughly, ensuring the discharging effect. The overall structure is simple and the production cost is low. During the discharging process of the silicon powder driven by the rotation of the spiral blade 53, the scraping plate 7 is driven to rotate. Through the scraping plate 7, the materials on the inner walls of the cylinder 1 and the discharge pipe 6 can be scraped off, further ensuring the discharging effect.
