In addition, the terms "first", "second" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0039] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "arrangement", "connection" should be understood broadly, for example, can be fixedly connected, can also be detachably connected, or integrally connected, can be directly connected, or indirectly connected through an intermediate medium, or can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0040] The anti-splashing separation gangue chute in the present application is mainly applied in the transfer and conveying process of the screened gangue in the coal preparation plant. Specifically, by changing the structure of the gangue chute, the replacement and maintenance of the screen plate inside the gangue screening mechanism are optimized, and the top splashing of the gangue in the conveying process from the screening mechanism to the gangue chute is reduced, the cleanliness of the workshop floor is ensured, and the labor intensity of workers is reduced.

[0041] Referring to Figure 1 , and in combination with Figures 2-3 , the anti-splashing separation gangue chute in the present application, the main structure includes a gangue chute, wherein the gangue chute further includes a chute feeding section 1 and a chute discharging section 2 arranged in a split manner, the chute feeding section 1 and the gangue screening mechanism 3 are arranged on the same high floor, and the chute discharging section 2 is arranged on the roof of the low floor.

[0042] By splitting the gangue chute into the chute feeding section 1 and the chute discharging section 2, the chute feeding section 1 can be individually disassembled on the high floor, and the disassembly operation amount during the replacement and maintenance of the screen plate of the gangue screening mechanism 3 is reduced.

[0043] Meanwhile, based on the connection and installation of the chute feeding section 1 after penetrating through the floor 4 and the chute discharging section 2, the reliable transfer and conveying of the gangue material in the gangue chute can be ensured.

[0044] The chute discharge section 2 is fixedly installed on the top of the low floor and is arranged above the gangue downstream conveying equipment, for example, above the scraper material lifting machine or the conveying belt, to ensure effective conveying of the gangue material.

[0045] The chute feeding section 1 is detachably installed on the ground of the high floor, which facilitates separate disassembly of the chute feeding section 1 on the high floor and ensures the operation space.

[0046] After the gangue material is treated by the gangue screening machine 3, the gangue material is transferred into the gangue downstream conveying equipment through the gangue chute. In the process of receiving the material on the high floor, in order to prevent the gangue blocks on the screen from splashing outward, the movable corner cover plate 5 is arranged on the chute feeding section 1 to form a shielding structure on the chute feeding section 1, which can block the splashed gangue blocks and make them change direction to fall, thereby avoiding scattering on the outside of the chute feeding section 1 and ensuring the cleanliness of the workshop floor and reducing the workload of maintenance and cleaning.

[0047] In one specific embodiment, the chute discharge section 2 is fixedly installed on the top of the low floor, and only the chute feeding section 1 needs to be disassembled on the high floor when the gangue chute is disassembled.

[0048] In order to reduce the sealed conveying of the gangue material between the two sections, from the perspective of structural composition, the outer contour of the bottom of the chute feeding section 1 is smaller than that of the top of the chute discharge section 2, which can enable the bottom of the chute feeding section 1 to be inserted into the space of the chute discharge section 2.

[0049] From the perspective of detachable and fixed installation of the chute feeding section 1 on the high floor, the installation plate 6 is pre-buried on the ground of the high floor, the high-strength bolt 7 is connected to the installation plate 6, the lifting lug 11 is arranged on the outer side wall of the chute feeding section 1 in the length direction, and the lifting lug 11 is arranged on the ground of the high floor and passes through the high-strength bolt 7 and is fixed and pre-tightened by the high-strength nut 8.

[0050] Specifically, the lifting lug 11 is welded on the outer side wall of the chute feeding section 1 in the length direction, and the lifting lug 11 can be positioned opposite to the installation plate 6 pre-buried on the ground during installation. The high-strength bolt 7 can pass through the through hole on the lifting lug 11 and make the lifting lug 11 fit with the installation plate 6, and then the high-strength nut 8 can be connected to the high-strength bolt 7 to fix the chute feeding section 1 in the length direction.

[0051] Through the above setting form, the chute feeding section 1 can be reliably fixed on the ground, and when disassembled, only simple hand hoist lifting equipment is needed to disassemble and lift the chute feeding section 1, while ensuring the stable and reliable degree of installation of the chute feeding section 1 on the ground of the high floor.

[0052] Further, in order to ensure the fixed installation of the chute feeding section 1 in the width direction, a support column 9 is installed on the ground of the high floor, and a butt cap 12 is welded on the outer side wall of the chute feeding section 1 in the width direction, which is buckled on the top end of the support column 9.

[0053] The butt cap 12 is a welded steel plate groove structure, which can provide lateral support for the chute feeding section 1 by buckling the butt cap 12 on the top end of the support column 9, and in combination with the pre-tightening of the lifting lug 11 and the mounting plate 6, it ensures that the chute feeding section 1 is effectively and stably supported and fixed on the high floor.

[0054] It should be further pointed out that the side wall of the chute feeding section 1 is also provided with a lifting lug (not shown in the figure) for lifting equipment to lift, which can facilitate lifting and disassembly operation.

[0055] In another specific embodiment, from the perspective of preventing coal rejects from splashing, the corner cover plate 5 is reversibly connected to the top of the chute feeding section 1 through the hinge 51, and the risk of coal rejects splashing is avoided at the junction between the coal rejects screening machine 3 and the top of the chute feeding section 1.

[0056] Through the reversible connection form, the corner cover plate 5 can be turned open when the machine is stopped, forming a maintenance space for the coal rejects chute, so that necessary dredging can be carried out.

[0057] The hinge 51 is provided on the outer side wall of the chute feeding section 1 in the length direction, specifically including two spaced apart hinges, which can meet the support of the corner cover plate 5 in the turned state and the buckled state.

[0058] In addition to being reversible, the fixing of the corner cover plate 5 also needs to be considered. Specifically, a cover plate hook 13 is installed on the top of the chute feeding section 1 in the width direction, which is rotatably installed on the side wall of the chute feeding section 1 in the width direction and located near the top of the chute feeding section 1.

[0059] The outer side wall of the corner cover plate 5 is provided with a hooking pin 52, and the cover plate hook 13 can be hooked and connected with the hooking pin 52 when it is turned clockwise, for fixing the turned and buckled corner cover plate 5 on the top notch of the chute feeding section 1.

[0060] Meanwhile, in the hooking and fitting state, the cover plate hook 13 can be rotated counterclockwise to be separated from the hooking pin 52, and then the corner cover plate 5 can be turned outward to be separated from the sealing of the top notch of the chute feeding section 1, thereby providing the maintenance space for the chute feeding section 1 and the whole gangue chute.

[0061] From the structure of the corner cover plate 5, the corner cover plate 5 comprises a horizontal plate 53 arranged vertically and bent to turn, and a vertical plate 54, and side plates 55 are connected to both sides of the corner cover plate 5, so as to form the closed structure of the corner cover plate 5 to the top of the chute feeding section 1.

[0062] In order to avoid the discharge of the gangue screening machine 3 from the top, the horizontal plate 53 is flush with the top of the outlet of the gangue screening machine 3, and can completely wrap the top discharge part of the gangue screening machine 3, so as to ensure the closed and intact shielding effect.

[0063] The hooking pin 52 is connected to the outer side wall of the side plate 55 and is arranged on both sides in the length direction of the corner cover plate 5, and the cover plate hook 13 is also arranged on the outer side wall of both sides in the length direction of the chute feeding section 1, so as to form the two-side fixed clamping of the cover plate hook 13 and the hooking pin 52, and then ensure the stable and reliable fixed cover.

[0064] In one preferred embodiment, in order to observe the screen plate of the gangue screening machine and the inside of the gangue chute during operation or in the shutdown state, a chute observation door 14 is arranged below the hinge 51, an observation opening for observing the screen plate condition in the gangue screening machine 3 is arranged on the side wall of the chute feeding section 1, and the chute observation door 14 is connected to the observation opening in a flat opening mode.

[0065] It should be pointed out that the chute feeding section 1 in the utility model can be open on the side, and the structure of the discharge part of the gangue screening machine is closed on the other side of the chute observation door 14, so that the screen plate condition of the gangue screening machine and the inside condition of the gangue chute can be observed through the observation opening at the same time, and the disassembly and maintenance amount of the chute feeding section 1 can also be reduced through the setting mode.

[0066] Further, the maintenance rack 10 can be moved, and the maintenance rack 10 is arranged directly below the chute observation door 14, so that the operation platform for maintenance can be provided through the setting of the maintenance rack 10, and the maintenance operation is facilitated.

[0067] Through the setting of the corner cover plate 5, the top of the chute feeding section 1 can be opened in the working condition with small maintenance amount, and small-range maintenance can be carried out.

[0068] It should be noted that the features of the embodiments in the present application can be combined with each other in the case of no conflict.

[0069] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. The present application can have various modifications and changes for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
