[0002] Belt conveyors are common equipment in bulk material transfer systems such as power plants and ports. In order to prevent dust from spilling out at the transfer points of belt conveyors, sealed dust suppression equipment will be installed according to actual conditions. The sealed material guide trough is the most common equipment to prevent dust from spilling out at the transfer points on belt conveyors. Its core purpose is to seal the dust raised at the impact point in the sealed area of ​​the material guide trough for automatic sedimentation. Therefore, improving the sealing performance of the sealed material guide trough becomes the focus.

[0003] However, the lining plate or sealing skirt plate of the existing guide chute equipment is very easy to wear after use. When inspecting or replacing the lining plate, workers often need to drill into the narrow space of the guide chute to operate, which is very troublesome. In addition, the existing guide chute equipment has the problem that the end is not tightly sealed and the top of the cover plate is prone to water and dust accumulation. Therefore, the key to solving the problem is to design a reasonable sealing structure. Utility Model Content

[0030] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0031] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0032] like Figure 1-2As shown, this embodiment provides a liner external sealed material guide trough, comprising a protective cover with open ends arranged along the length direction of the conveyor belt, the protective cover comprising a top cover 1, side panels 2 installed on both sides of the bottom of the top cover 1, liner 3 installed on the outer side wall of the side panel 2, the side panel 2 and the liner 3 are sealed and attached, and a sealing skirt 9 adapted to the conveyor belt is provided at the bottom of the liner 3;

[0033] The side plate 2 is fixed to the belt conveyor frame 10 via a supporting structure 5 .

[0034] In this embodiment, the lining plate 3 is installed on the outside of the side plate 2, and the sealing skirt plate 9 is arranged at the bottom of the lining plate 3. In this way, when the lining plate 3 or the sealing skirt plate 9 is worn, the lining plate 3 can be directly removed from the outside without removing the side plate 2, thereby effectively improving the convenience of daily inspections and the timeliness of damaged replacement, and avoiding the situation where the staff need to drill into the narrow space of the material guide trough to operate when removing or installing the liner.

[0035] In this embodiment, the lining plate 3 is a wear-resistant plate, which can increase its service life.

[0036] The side plates 2 and the lining plates 3 both adopt a straight plate structure. After installation, the cross-section of the material guide trough is similar to a rectangular structure, which prevents the materials falling from the chute from directly impacting the side plates 2, the lining plates 3 and the sealing skirt plate 9, thereby improving the service life of the entire equipment.

[0037] In this embodiment, a plurality of lining plates 3 are attached to the outer side wall of the side plate 2, and the plurality of lining plates 3 are connected end to end in sequence along the length direction of the conveyor belt. In this way, when some of the lining plates 3 are worn, a single lining plate 3 can be disassembled without disassembling all the lining plates, which saves time and effort.

[0038] In this embodiment, a connecting plate 32 is fixed on the outer wall of the lining plate 3, and the connecting plate 32 is penetrated by first through holes 31 from top to bottom. A base plate 33 is fixed on the outer wall of the side plate 2, and the base plate 33 is penetrated by mounting holes from top to bottom. The base plate 33 is connected to the connecting plate 32 by adjusting bolts 11. For example, Figure 3-4 As shown, the bottom end of the adjusting bolt 11 passes through the mounting hole and the first through hole 31 from top to bottom in sequence, and is finally screwed with the nut. At this time, the connecting plate 32 overlaps the nut, and the nut can play a limiting role to prevent the connecting plate 32 from moving downward, so that the lining plate 3 can be installed on the outer wall of the side plate 2. Moreover, by adjusting the height position of the nut, the height position of the connecting plate 32 can be adjusted, and then the height position of the lining plate 3 can be adjusted, and the sealing performance is better when combined with the sealing skirt plate 9.

[0039] The first through hole 31 may be a strip hole, the length direction of the first through hole 31 is perpendicular to the lining plate 3, a pressing plate 4 is provided on the outside of the lining plate 3, a screw hole is provided on the outer wall of the side plate 2, a locking bolt 12 is screwed into the screw hole, the pressing plate 4 is provided with a second through hole adapted to the locking bolt 12, the locking bolt 12 is inserted into the second through hole, and the end cap of the locking bolt 12 is pressed against the outside of the pressing plate 4, so that the inner wall of the pressing plate 4 abuts against the outer wall of the lining plate 3. The pressing plate 4 may be a bent plate, which has a better pressing effect on the lining plate 3.

[0040] Based on the above structure, the adjusting bolt 11 can move back and forth in the first through hole 31, that is, the lining plate 3 can gradually approach or move away from the side plate 2, that is, the spacing distance between the lining plate 3 and the side plate 2 can be adjusted. When the distance is adjusted to a suitable distance, the pressing plate 4 is gradually approached to the side plate 2 by rotating the locking bolt 12, and the pressing plate 4 presses the lining plate 3 against the outside of the side plate 2, thereby improving the stability of the lining plate 3. As needed, a sealing gasket can be sandwiched between the lining plate 3 and the side plate 2 to enhance the sealing performance between the lining plate 3 and the side plate 2.

[0041] In this embodiment, the top cover 1 is an arched structure. The top cover 1 can be a steel cover, and the arched structure design is not easy to accumulate water, which is convenient for daily cleaning of dust and maintenance.

[0042] The end of the protective cover is provided with a sealing box 6, such as Figure 5 As shown, the sealing box 6 is provided with four layers of rubber sheets 61, and the four layers of rubber sheets 61 are arranged at intervals, so as to effectively ensure the sealing of the end of the protective cover.

[0043] The support structure 5 is an F-shaped support column with a diagonal brace, the bottom end of the F-shaped support column is fixed to the belt conveyor frame 10, and the top end of the F-shaped support column is fixed to the side plate 2. The F-shaped support column is connected to the side plate 2 at two locations, providing better vertical and horizontal support for the guide trough, thereby ensuring the stability of the equipment during use.

[0044] In this embodiment, the sealing skirt plate 9 may adopt a Y-shaped double-layer structure. Figure 6-7 As shown, the sealing skirt 9 includes a vertical plate 13, and the lower end of the inner plate surface of the vertical plate 13 is provided with a first sealing member 15 that cooperates with the top surface of the conveyor belt along its length direction, and the outer plate surface of the vertical plate 13 is provided with a mounting portion 14 extending outward along its length direction, and the outer bottom of the mounting portion 14 is provided with a second sealing member 16 that cooperates with the top surface of the conveyor belt along its length direction. The first sealing member 15 and the second sealing member 16 can both be made of polyurethane material, which effectively ensures the sealing of both sides of the material guide trough.

[0045] The outer wall of the lining plate 3 is provided with a clamping structure 8 for clamping and fixing the vertical plate 13. The clamping structure 8 is an existing structure and will not be described in detail here.

[0046] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
