[0021] On the bottom of one side of the adjacent scrapers 11, there is a base plate 9 consisting of several base plates 22 and several sets of connecting blocks 23. Two connecting slots 20 are symmetrically arranged on one side of the base plate 22. Two connecting strips 18 are arranged on both sides of the scraper 11. A fixing groove 21 is arranged in the middle of one side of the base plate 22. A fixing clip 19 is arranged on the scraper 11 in the middle of the two connecting strips 18.
[0022] Further improvements include connecting the two ends of the conveyor box 1 to the conveyor drive box 6 and the discharge box 4, respectively. The side of the conveyor drive box 6 is equipped with a drive assembly 7, the power end of which is connected to one end of the scraper. The top of the conveyor box 1 is integrally connected with an inlet 5, and the bottom of the discharge box 4 is equipped with a discharge port 2. Several maintenance panels 3 are arranged on the top of the conveyor box 1. Specifically, the maintenance panels 3 are fixedly connected to the conveyor box 1 with bolts to facilitate subsequent maintenance work.
[0023] Further improvements include a scraper 11 with an overall "T" shape, with both ends of the chain post 10 rotatably connected to the scraper 11, and the mounting through hole 16 being fixed by bolts and nuts. The mounting side plate 17 is fixed to the fixed side block 8, and one side of the fixed side block 8 is attached to the inner wall of the conveyor box 1.
[0024] In a further improvement, the number of single first connecting side plates 15 is two, and the end of the second connecting side plate 13 is rotatably connected to the single first connecting side plate 15 via a rotating shaft 14. One end of the second connecting side plate 15 is fixedly connected to the fixed side block 8.
[0025] In a further improvement, the bottom of the base plate 22 is located on the bottom inner wall of the conveyor box 1, and a single set of connecting blocks 23 is located between adjacent base plates 22. The side of the base plate 22 is provided with a groove for connecting the connecting blocks 23, and the connecting blocks 23 and the base plate 22 are rotatably connected.
[0026] In a further improvement, the connecting slot 20 is engaged with the connecting strip plate 18 and both are in a "T" shape. The fixing slot 21 is a rectangular slot structure. The fixing clip 19 includes a strip plate, a supporting side plate, and a fastening bolt. The strip plate is fixed on the scraper 11, and the fastening bolt is on the supporting side plate and threadedly connected to the base plate 22. Specifically, after the base plate 22 moves to the bottom position of the strip plate through the fixing slot 21, one end of the supporting side plate is fixed to the strip plate with a bolt, and then the fastening bolt is passed through the supporting side plate and threadedly connected to the base plate 22.
[0027] In use: First, the base plate 9 is placed between the scrapers 11. Simultaneously, the connecting slot 20 is engaged with the connecting strip plate 18, and the fixing slot 21 is engaged with the strip plate in the fixing piece 19. The base plate 9 is then gradually lowered until its bottom contacts the inner wall of the conveyor box 1. Then, the fastening bolts are passed through the support plate and threaded onto the base plate 22 to fix the base plate 9. After completion, the fixing side block 8 is placed on the end of the scraper 11 via the mounting side plate 17, with its side fitting against the inner wall of the conveyor box 1. Next, the bolt is passed through the mounting through hole 16 and connected with the nut to fix the side plate 8. Then, the first connecting side plate 15 and the second connecting side plate 13 are connected by the rotating shaft 14. When the material falls into the conveying box 1 through the feed port 5, it will fall onto the scraper, the bottom plate 9 and the connecting side baffle 12, and will not contact the conveying box 1. When the scraper is driven by the drive assembly 7, the material will not rub against the scraper 11 and the conveying box 1, which reduces the wear on the scraper 11 and improves the service life of the scraper.
[0028] The components of this utility model are: conveyor box-1, discharge port-2, maintenance box plate-3, discharge box-4, inlet-5, conveyor drive box-6, drive assembly-7, fixed side block-8, bottom plate-9, chain column-10, scraper-11, connecting side baffle-12, second connecting side plate-13, rotating shaft-14, first connecting side plate-15, mounting through hole-16, mounting side plate-17, connecting clip plate-18, fixing clip-19, connecting slot-20, fixing slot-21, bottom plate-22, and connecting block-23. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is the lack of connection between the scraper and the scraper box plate. The gaps between the scraper and the material make it easy for the material to fall onto the conveyor box, causing constant friction and excessive wear, which affects the stable use of the scraper and increases maintenance costs. This invention addresses this problem by combining the aforementioned components, specifically the connecting side plate and bottom plate, to effectively cover the gaps between adjacent scrapers and the inner wall of the conveyor box. When material enters the conveyor box through the inlet, it falls onto the scraper and the bottom plate, preventing it from falling directly onto the inner wall of the conveyor box. When the subsequent tube plate is rotated and conveyed by the drive assembly, the material is prevented from being positioned between the bottom of the scraper and the conveyor box, thus avoiding continuous friction between the scraper and the conveyor box and material, reducing scraper wear, increasing scraper lifespan, and lowering equipment maintenance requirements.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
