[0036] Embodiments
[0037] As Figures 1-9As shown, the discharge funnel provided by the embodiment of the application comprises a funnel body 1, a lower protection structure 2 and an upper protection structure 3. The lower protection structure 2 comprises a first front lining plate 4, a first left lining plate 5, a first rear lining plate 6 and a first right lining plate 7. At least one first clamping groove 8 is arranged on each of the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 and the first right lining plate 7. A plurality of first clamping blocks 9 are arranged on the inner wall of the lower end of the funnel body 1. The number of the first clamping blocks 9 is the same as and corresponds to the number of the first clamping grooves 8. A lower stop block 10 is arranged on the funnel body 1. The lower stop block 10 is used to support the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 and the first right lining plate 7.
[0038] When the lower protection structure 2 is installed, the first clamping grooves 8 are aligned with the first clamping blocks 9, and then the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 or the first right lining plate 7 is slowly lowered. The stability of the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 or the first right lining plate 7 can be improved under the cooperation of the first clamping grooves 8 and the first clamping blocks 9. The first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 and the first right lining plate 7 can be supported by the lower stop block 10. Therefore, the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 and the first right lining plate 7 can be installed in the inner lower end of the funnel body 1 without using the bolts 15. The assembly cost is reduced, and the assembly efficiency is improved.
[0039] The upper protection structure 3 comprises a second front lining plate 11, a second left lining plate 12, a second rear lining plate 13 and a second right lining plate 14. The second front lining plate 11 and the second rear lining plate 13 are fixed on the inner wall of the upper end of the funnel body 1 by the bolts 15. The second left lining plate 12 and the second right lining plate 14 are provided with grooves 16 and at least one second clamping groove 17. The inner wall of the upper end of the funnel body 1 is provided with a first upper stop block 18, a second upper stop block 19 and at least two second clamping blocks 20. The first upper stop block 18 is used to support the second left lining plate 12. The second upper stop block 19 is used to support the second right lining plate 14. The number of the second clamping blocks 20 is the same as and corresponds to the number of the second clamping grooves 17.
[0040] When the upper protection structure 3 is installed, the second front lining plate 11 and the second rear lining plate 13 are fixed on the upper end of the funnel body 1 by the bolts 15. After the installation of the second front lining plate 11 and the second rear lining plate 13 is completed, the lower end of the second front lining plate 11 is overlapped above the first front lining plate 4, and the lower end of the second rear lining plate 13 is overlapped above the second rear lining plate 13. Then, the second clamping groove 17 is aligned with the second clamping block 20. Then, the second left lining plate 12 or the second right lining plate 14 is slowly pushed. At this time, the second clamping block 20 enters the second clamping groove 17, and the first upper stop block 18 or the second upper stop block 19 enters the groove 16. Under the cooperation of the second clamping groove 17 and the second clamping block 20, the stability of the second left lining plate 12 or the second right lining plate 14 can be improved. Finally, the second left lining plate 12 is limited by the first upper stop block 18, and the second right lining plate 14 is limited by the second upper stop block 19. Thus, the second left lining plate 12 and the second right lining plate 14 can be installed on the upper end of the funnel body 1 without using the bolts 15. After the installation of the second left lining plate 12 and the second right lining plate 14 is completed, the lower end of the second left lining plate 12 is overlapped above the first left lining plate 5, and the lower end of the second right lining plate 14 is overlapped above the second right lining plate 14. Since the coal dropping point is on the second left lining plate 12, the impact of the coal on the second left lining plate 12 is the largest, and therefore the second left lining plate 12 is replaced most frequently. The above structure can facilitate the replacement of the second left lining plate 12, reduce the labor intensity of the workers, and improve the work efficiency.
[0041] In the embodiment, the first clamping groove 8 and the first clamping block 9 are dovetail structures. The dovetail structures of the first clamping groove 8 and the first clamping block 9 are used in cooperation, which can improve the stability of the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6, and the first right lining plate 7, and facilitate the disassembly and assembly of the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6, and the first right lining plate 7.
[0042] In the embodiment, the lower stop block 10 is a rectangular frame structure. In specific implementation, after the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6, and the first right lining plate 7 are respectively contacted with the lower stop block 10, gaps are arranged between the side of the first front lining plate 4 away from the first clamping groove 8, the side of the first left lining plate 5 away from the first clamping groove 8, the side of the first rear lining plate 6 away from the first clamping groove 8, the side of the first right lining plate 7 away from the first clamping groove 8, and the lower stop block 10. When the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6, or the first right lining plate 7 needs to be replaced, the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6, or the first right lining plate 7 can be easily taken out.
[0043] In the embodiment, the lower stop block 10 is welded on the inner wall of the funnel body 1. The welding manner can improve the firmness of the lower stop block 10.
[0044] In the embodiment, the second clamping groove 17 and the second clamping block 20 are dovetail structures, the dovetail structure of the second clamping groove 17 and the second clamping block 20 are used in cooperation, the stability of the second left lining plate 12 and the second right lining plate 14 can be improved, and the second left lining plate 12 and the second right lining plate 14 can be conveniently disassembled and assembled.
[0045] In the embodiment, the first upper stop block 18 and the second upper stop block 19 are welded on the inner wall of the funnel body 1, and the welding can improve the firmness of the first upper stop block 18 and the second upper stop block 19.
[0046] In the embodiment, the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 and the first right lining plate 7 are provided with recessed portions 21 at two ends away from the first clamping groove 8, and the recessed portions 21 can facilitate the splicing between the first front lining plate 4, the first left lining plate 5, the first rear lining plate 6 and the first right lining plate 7.
[0047] The above only is the preferred embodiment of the application, and is not used for limiting the application, and the application can have various changes and changes for the person skilled in the art. Any modification, equivalent replacement, improvement and the like within the spirit and principle of the application should be included in the protection scope of the application.
