[0028] Reference Figure 1-Figure 8A fine particle ascending conveying device comprises an ascending conveying belt 1 and a rotating shaft 2 arranged at both ends of the ascending conveying belt 1, on which a motor 3 is arranged, and further comprises: an L-shaped plate 4 arranged at both ends of the top of the ascending conveying belt 1; a conveying plate 5 fixedly connected to the ascending conveying belt 1; a slider 6 slidably connected in the L-shaped plate 4, a spring 7 fixedly connected to the bottom of the slider 6, and a moving plate 8 fixedly connected to the outside of the slider 6; a rack 9 fixedly connected to the left side of the moving plate 8; a rotating rod 10 rotatably connected to the L-shaped plate 4, and a gear 11 is fixedly sleeved on the rotating rod 10; a first winding roller 12 is fixedly connected to the rotating rod 10, and a first cable 13 is sleeved on the first winding roller 12; a fixed plate 14 is fixedly connected to the inner wall of the L-shaped plate 4, and a second winding roller 15 is rotatably connected to the fixed plate 14, and a second winding roller 15 is sleeved on the second winding roller 15 Two cables 16, a clockwork spring 1501 is fixedly set in the fixed plate 14; the guide plate 17 is fixedly connected between the two L-shaped plates 4, and a scraper 18 is slidably connected to the guide plate 17. When the fine particles are transported, the motor 3 drives the ascending conveyor belt 1 to rotate through the rotating shaft 2, and drives the conveying plate 5 to rotate. When the conveying plate 5 rotates to the L-shaped plate 4, the movable plate 8 is squeezed, so that the movable plate 8 slides downward through the slider 6, and drives the rack 9 to slide downward and mesh with the gear 11, so that the gear 11 can rotate, and drive the rotating rod 10 to rotate. The rotating rod 10 drives the first winding roller 12 to rotate. When the first winding roller 12 rotates, the first cable 13 is stretched, thereby pulling the scraper 18 to slide from one end of the conveying plate 5 to the other end of the conveying plate 5, so that the residual powder material on the conveying plate 5 is scraped off and falls into the receiving hopper 24, thereby avoiding waste.

[0029] A slide groove is provided on the surface of the L-shaped plate 4, and the slider 6 is slidably connected in the slide groove of the L-shaped plate 4. The end of the spring 7 away from the slider 6 is fixedly connected to the inner wall of the bottom of the slide groove of the L-shaped plate 4. When the movable plate 8 is pressed downward by the conveying plate 5, the slider 6 can slide downward in the slide groove of the L-shaped plate 4 to guide the movable plate 8. The spring 7 helps to automatically reset the movable plate 8 to facilitate scraping the surface of the conveying plate 5 next time.

[0030] One end of the first cable 13 is fixedly connected to the first winding roller 12, and the other end of the first cable 13 is fixedly connected to the left side of the scraper 18. When the first winding roller 12 rotates following the rotating rod 10, the first cable 13 can be wound up, so that the first cable 13 can pull the scraper 18 to slide on the conveying plate 5.

[0031] One end of the second cable 16 is fixedly connected to the second winding roller 15, and the other end of the second cable 16 is fixedly connected to the right side of the scraper 18. A groove is provided on the surface of the fixed plate 14, and one end of the spring 1501 is fixedly connected to the inner wall of the groove of the fixed plate 14, and the other end of the spring 1501 is fixedly connected to the second winding roller 15. When the scraper 18 is pulled by the first cable 13, the second winding roller 15 will scale the second cable 16, and the second winding roller 15 will rotate to stretch the spring 1501. When the conveying plate 5 no longer contacts the moving plate 8, the second winding roller 15 can tighten the spring 1501 to drive the second winding roller 15 to wind and reel the second cable 16, so that the scraper 18 is automatically reset.

[0032] The scraper 18 passes through the guide plate 17 and is slidably connected to the guide plate 17. The guide plate 17 passes through the limit plate 19 and is fixedly connected to the guide plate 17. The scraper 18 can be guided by the guide plate 17 when it is pulled and reset, so that the scraper 18 can slide stably horizontally when scraping the conveyor plate 5. When the scraper 18 slides to the limit plate 19, it cannot continue to slide, which can avoid affecting the sliding reset of the movable plate 8.

[0033] The gear 11 meshes with the rack 9 , and the gear 11 passes through the rotating rod 10 and is fixedly connected to the rotating rod 10 . The rack 9 can make the gear 11 rotate forward and reverse, and control the first winding roller 12 to perform forward winding and reverse zooming.

[0034] A first support plate 20 is placed at the bottom of the rotating shaft 2 near the bottom of the ascending conveyor belt 1, and a second support plate 21 is placed at the bottom of the rotating shaft 2 near the top of the ascending conveyor belt 1. The rotating shaft 2 is rotatably connected to the first support plate 20 and the second support plate 21, and the first support plate 20 and the second support plate 21 support the rotating shaft 2 and the ascending conveyor belt 1.

[0035] A connecting plate 22 is fixedly connected to the right surface of the second support plate 21, two vertical plates 23 are fixedly connected to the top of the connecting plate 22, a receiving hopper 24 is fixedly connected between the two vertical plates 23, a horizontal plate 25 is fixedly connected to the surface of the second support plate 21, the output end of the motor 3 is fixedly connected to the rotating shaft 2, and the bottom of the motor 3 is fixedly connected to the horizontal plate 25.

[0036] In the utility model, the starting motor 3 drives the rotating shaft 2 to rotate, and the rotating shaft 2 drives the ascending conveyor belt 1 to ascend and convey the fine granular materials, and the fine granular materials are placed between the two conveying plates 5 for conveying, and then when the conveying plate 5 rotates to the receiving hopper 24, the fine granular materials are collected, and at this time, the conveying plate 5 will press the moving plate 8 downward, so that the moving plate 8 slides downward in the slide groove of the L-shaped plate 4 through the slider 6 and the compression spring 7, thereby driving the rack 9 to slide down and mesh with the gear 11, so that the gear 11 rotates, driving the first winding roller 12 to rotate to wind up the first cable 13, and the first cable 13 pulls the scraper 18 to scrape the powdery materials remaining on the conveying plate 5. At this time, the scraper 18 pulls the second cable 16 to rotate on the second winding roller 15, and the second winding roller 15 expands and contracts while stretching the spring 1501. When scraping is completed, the conveying plate 5 rotates to disengage from the moving plate 8. Under the action of the spring 7, the moving plate 8 is reset, driving the rack 9 to slide up, meshing with the gear 11 to reverse it, driving the first winding roller 12 to expand and contract the first cable 13, and the second winding roller 15 drives the second winding roller 15 to rewind the second cable 16 under the action of the tightening of the spring 1501, thereby pulling the scraper 18 to reset. With this reciprocating operation, the residual material on each conveying plate 5 can be scraped and dropped into the receiving hopper 24 to avoid waste.
