[0025] To facilitate the understanding of the present application, the present application will be described more comprehensively below with reference to the relevant attached drawings. Embodiments of the present application are shown in the attached drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0027] Embodiment 1

[0028] Please refer to Figure 1 , the present utility model provides a residue-free scraper conveyor housing, which includes a machine housing 1 and a transmission chain 2 arranged inside the machine housing 1. The machine housing 1 includes a bottom plate 11 and side plates 12 arranged on both sides of the bottom plate 11. Among them, the transmission chain 2 is arranged above the bottom plate 11 and extends along the length direction of the machine housing 1. A plurality of connecting plate groups are arranged at intervals along the length direction of the transmission chain 2, and each connecting plate group includes two connecting plates 3 symmetrically fixed on both sides of the transmission chain 2.

[0029] A material scraper 4 is detachably installed on the surface of each connecting plate 3. An inclined chamfer 41 is formed at one end of the material scraper 4 away from the connecting plate 3. At the same time, trapezoidal inclined surfaces 111 are formed by recessing near both sides of the bottom plate 11, so that the cross section of the bottom plate 11 is trapezoidal, and the inclined chamfer 41 of the material scraper 4 matches the trapezoidal inclined surface 111 inside the bottom plate 11.

[0030] In this application, by providing a bottom plate 11 with a trapezoidal inclined surface 111 and a material scraping plate 4 with an inclined chamfer 41, the shape of the material scraping plate 4 matches the shape of the bottom plate 11. On the one hand, it enables the material near the side plate 12 in the housing 1 to flow along the trapezoidal inclined surface 111 towards the center of the bottom plate 11, and then drives the material scraping plate 4 to move by means of the transmission chain 2 to achieve the transportation of the material; on the other hand, the matching shape of the material scraping plate 4 and the bottom plate 11 enables the material scraping plate 4 to discharge the material in the casing 1 as much as possible, reducing the situation of material accumulation in the gap between the material scraping plate 4 and the bottom plate 11, effectively reducing material waste and the mixing of new and old materials.

[0031] Furthermore, the bottom plate 11 is detachably installed on the lower surface of the side plate 12. Specifically, the side plate 12 is in an L shape, and one side panel of the side plate 12 is attached to the bottom plate 11. The bottom plate 11 and the side plate 12 are relatively fixed by a plurality of bolts and nuts. During later maintenance, the bottom plate 11 can be detached as a whole, which provides convenience for cleaning or repairing and replacing the bottom plate 11 later.

[0032] Embodiment 2

[0033] The difference between Embodiment 2 and Embodiment 1 lies in that, referring to Figures 2 - 4 , the connecting plate 3 includes a first plate surface 31 and a second plate surface 32. The second plate surface 32 is vertically fixed on the first plate surface 31, and the first plate surface 31 is sleeved and fixed outside the pin shaft of the transmission chain 2. A reinforcing rib plate 33 is welded between the first plate surface 31 and the second plate surface 32. By providing the reinforcing rib plate 33, the connection firmness between the first plate surface 31 and the second plate surface 32 and the bending moment resistance ability of the connecting plate 3 can be improved.

[0034] Through holes are provided on the surfaces of both the material scraping plate 4 and the second plate surface 32. A first bolt 5 is inserted into the through holes. A first nut 6 is threadedly connected to the first bolt 5. Inserting the first bolt 5 into the through holes of both the material scraping plate 4 and the second plate surface 32 and tightening the first nut 6 can achieve the relative fixation between the second plate surface 32 and the material scraping plate 4; by disassembling the first bolt 5 and the first nut 6, it is also convenient to disassemble and replace the material scraping plate 4.

[0035] A cross positioning post 42 is fixedly connected to the surface of the material scraping plate 4, and a cross groove 321 is provided on the surface of the second plate surface 32. When the material scraping plate 4 is installed and fixed to the second plate surface 32, the cross positioning post 42 is inserted into the cross groove 321. By providing the cross positioning post 42 and the cross groove 321, the connection firmness between the material scraping plate 4 and the second plate surface 32 can be improved, reducing the occurrence of the situation where the material scraping plate 4 rotates relative to the second plate surface 32, and at the same time facilitating the alignment of the through holes on the surfaces of the material scraping plate 4 and the second plate surface 32.

[0036] Furthermore, a plurality of mounting seats 7 are rotatably connected to the surface of the side plate 12 , and a triangular groove 71 is provided on the surface of the mounting seat 7 , and a bulking mechanism 8 is detachably mounted on the mounting seat 7 .

[0037] The material dispersing mechanism 8 comprises a central rod 81 and a plurality of material dispersing rods 82 fixed in a circular array on the outer surface of the central rod 81. Both ends of the central rod 81 are provided with cavities, and springs 83, movable disks 84, triangular plugs 85 and toggle plates 86 are arranged in the cavities. Specifically, the movable disk 84 is slidably arranged in the cavity, the spring 83 is fixedly connected between the movable disk 84 and the bottom wall of the cavity, the toggle plate 86 and the triangular plug 85 are both fixedly connected to the surface of the movable disk 84, and the triangular plug 85 passes through the end of the central rod 81, and the toggle plate 86 extends from the cavity to the side wall of the central rod 81.

[0038] The two ends of the center rod 81 can be respectively plugged into the mounting seats 7 at the two ends, and the center rod 81 and the side plate 12 are fixed by plugging the triangular plug 85 into the triangular groove 71. When removing the center rod 81, the operator only needs to push the toggle plate 86 to compress the spring 83, and the triangular plug 85 is retracted into the center rod 81, so that the connection between the center rod 81 and the side plate 12 can be contacted.

[0039] Since materials are prone to agglomeration during transportation, a dispersing mechanism 8 is provided. The movement of the material scraper 4 can push the dispersing rod 82, thereby rotating the center rod 81. The rotation of the center rod 81 can drive multiple dispersing rods 82 to rotate. The dispersing rod 82 moves the agglomerated materials, which can effectively break up the agglomerated materials, thereby facilitating the subsequent transportation and storage of the materials and improving the practicality. It should be noted that the dispersing rod 82 is not a hard rod. The dispersing rod 82 can be made of plastic. On the one hand, it has hardness to break up the materials, and at the same time, it has a certain flexibility to deform. When the dispersing rod 82 contacts the material scraper 4, the dispersing rod 82 deforms to reduce interference with the material scraper 4.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
