The bottom outer wall of the annular sleeve 61 is fixedly connected to a crushing plate 62. The crushing plate 62 is provided to crush the coal powder blocks stored in the coal powder tank. A drainage port 63 is provided on the side inner wall of the crushing plate 62. The bottom inner wall of the annular sleeve 61 is slidably connected to a scraper 64. The scraper 64 is provided to discharge the coal powder adhered to the inner wall of the tank. A compression spring 66 is fixedly connected to the outer wall of one side of the scraper 64.
[0025] Reference Figure 1-Figure 3 The crushing plate 62 is slidably connected to the bottom inner wall of the coal powder tank body 1, the scraper 64 is slidably connected to the side inner wall of the coal powder tank body 1, the annular sleeve 61 is rollingly connected to the side outer wall of the active roller 5, and the outer walls of both sides of the scraper 64 are provided with arc groove surfaces 65. One end of the compression spring 66 away from the scraper 64 is fixedly connected to the inner wall of one side of the annular sleeve 61, and a continuous thrust is generated by setting the compression spring 66 to the scraper 64. The top outer wall of the discharge top cover 4 is clamped with a pointed cone top cover 67. By setting the pointed cone top cover 67, the snow in the snow season can be angled and slided off, reducing the attachment to the top of the coal powder tank body 1 and increasing the support weight of the support foot 2. The side outer wall of the pointed cone top cover 67 is fixedly connected with an oleophobic layer, the bottom outer wall of the coal powder tank body 1 is fixedly connected to the support foot 2, the bottom outer wall of the coal powder tank body 1 is fixedly connected to the discharge valve 3, and the active roller 5 is rotatably connected to the bottom outer wall of the discharge top cover 4 through a bearing.
[0026] Reference Figure 3-Figure 4 The clamping force of the clamping plate 75 is applied to the clamping plate 74 to release the locking breaker 7 from the locking breaker 7. The locking breaker 7 is then engaged with the locking breaker 7 by locking the top cover 74 against the support 76.
[0027] Working principle: When discharging coal powder, the active roller 5 is rotated by opening the discharge top cover 4, and the rotation of the active roller 5 drives the annular sleeve 61 to rotate, and the rotation of the annular sleeve 61 drives the crushing plate 62 to rotate, and the crushing plate 62 rotates to stir and crush the coal powder blocks to prevent the coal powder blocks from clogging the discharge port. At the same time, the rotation of the annular sleeve 61 drives the scraper 64 to rotate, so that the scraper 64 scrapes and discharges the coal powder adhered to the inner wall of the coal powder tank body 1 to prevent old coal powder from adhering to the inner wall for a long time during later feeding, affecting the internal storage space of the coal powder tank body 1. When the feeding pipe touches the cover plate 74, the cover plate 74 rotates to insert the feeding pipe into the feeding port 71 for feeding. After the feeding is completed, the feeding pipe is pulled out, and then the torsion spring 73 twists the rotating rod 72 to rotate, and the rotation of the rotating rod 72 drives the cover plate 74 to rotate, so that the cover plate 74 closes the feeding port 71 again.
