[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1 to 6 As shown in the figure, the present invention provides a foldable dust collection cover for a mining sweeper, including a mounting base 1, a fixed cover 2 fixed in the middle of the mounting base 1, and movable covers 3 hinged to both sides of the fixed cover 2. Each movable cover 3 is provided with a transparent plate 8. The mounting base 1 is provided with a support assembly, which includes a support rod 4 on the mounting base 1. The support rod 4 is used to support the movable cover 3 when it is flipped open relative to the fixed cover 2. The support assembly also includes an insert block 5 fixed to the inner surface of the movable cover 3 and a locking block 6 fixed to the mounting base 1. One end of the support rod 4 is rotatably connected to the mounting base 1, and the other end of the support rod 4 can be inserted into the insert block 5. The insert block 5 has a hollow structure to form a slot for insertion with the support rod 4. The locking block 6 has a locking groove for insertion with the support rod 4.

[0021] The fixed hood 2 and the movable hood 3 form a sealed hood structure, which confines the spread of pollution sources to a small, enclosed space, thereby preventing dust from overflowing. However, the sealed hood also has certain limitations. Since the equipment requires regular maintenance, the design of the sealed hood may have some impact on equipment maintenance.

[0022] Therefore, this application provides freely opening and closing movable covers 3 on both sides of the fixed cover 2. By flipping the movable cover 3 outwards using the handle, the support rod 4 can be removed from the slot of the locking block 6, and its other end can be inserted into the slot of the insert block 5 on the inner side of the movable cover 3, thereby providing stable support for the movable cover 3 and facilitating safe operation or observation by personnel. When it is necessary to close the movable cover 3, the support rod 4 can be removed from the slot of the insert block 5 and inserted into the slot of the locking block 6 for positioning, and closing the movable cover 3 can seal off the pollution source.

[0023] By setting up an openable and closable movable cover 3, maintenance personnel do not need to disassemble the entire dust collection cover. They only need to unlock the mechanical locking component to flip and open the movable cover 3 and support it with the support rod 4, which facilitates quick exposure of the sweeper for maintenance and improves the efficiency of inspection and maintenance work.

[0024] In some specific implementation plans, such as Figure 4 As shown, each movable cover 3 is equipped with a mechanical locking assembly, which is used to prevent the movable cover 3 from separating from the mounting base 1 when locked. The mechanical locking assembly includes a positioning plate 16 fixed to the movable cover 3, a movable plate 17 slidably connected to the positioning plate 16, and a positioning screw 18 threadedly connected to the movable plate 17. A knob is fixed to the top of the positioning screw 18 for easy operation. A limiting plate 19 is fixed to the mounting base 1 on the side near the positioning plate 16. The movable plate 17 can be inserted into the limiting plate 19. Both the limiting plate 19 and the positioning plate 16 have through holes to facilitate insertion with the movable plate 17. A baffle is fixed to one end of the movable plate 17 to prevent the movable plate 17 from falling off the positioning plate 16 when the movable cover 3 is opened and closed.

[0025] After closing the movable cover 3, push the movable plate 17 to insert it into the through hole of the limiting plate 19, then tighten the positioning screw 18 to press the positioning plate 16, achieving mechanical locking and preventing the cover from opening accidentally during equipment operation. When opening the movable cover 3, loosen the positioning screw 18 to separate it from the positioning plate 16, move the movable plate 17 to slide inside the positioning plate 16, and the movable plate 17 will separate from the through hole of the limiting plate 19, allowing the movable cover 3 to be opened freely.

[0026] In some specific implementation plans, such as Figure 6As shown, to prevent dust from adhering to the transparent plate 8 and affecting observation, a frame 10 is fixed on the movable cover 3 and on the side near the transparent plate 8. The frame 10 has a cylindrical structure in the middle, and a cross-shaped plate is set on the outer ring to fix the cylinder to the movable cover 3. A rotating shaft 11 is rotatably connected to the middle of the frame 10. A rotating plate 12 is fixed at one end of the rotating shaft 11 near the inner side of the movable cover 3, and a handle is fixed at the other end of the rotating shaft 11. A scraper 13 that contacts the surface of the transparent plate 8 is fixed on the rotating plate 12. The scraper 13 is a flexible rubber scraper.

[0027] When dust accumulation on the inner transparent panel 8 obstructs the view, the handle can be turned to rotate the shaft 11 and the rotating plate 12, thereby causing the scraper 13 to scrape the inner surface of the transparent panel 8 to remove the dust, maintain a clear view, and facilitate observation of the internal operation of the equipment without the need to repeatedly open and close the movable cover 3.

[0028] In some specific implementation plans, such as Figure 5 As shown, sealing rings 7 are provided on the side of the movable cover 3 that fits with the mounting base 1 and the side that fits with the fixed cover 2. The connection between the movable cover 3 and the mounting base 1 and the fixed cover 2 forms a sealing barrier through the sealing rings 7, which can effectively prevent dust from overflowing.

[0029] In some specific implementation plans, such as Figure 1 , Figure 2 and Figure 3 As shown, a connecting duct 9 is fixed to the top of the fixed hood 2, and a flange is fixed to the top of the connecting duct 9, which connects the connecting duct 9 to the main pipeline of the dust removal system. Multiple fixing holes 15 are evenly distributed inside the mounting base 1. These holes are all oblong structures, facilitating the installation of the entire dust collection hood near the cleaning point of the mining equipment using bolts. Both the fixed hood 2 and the movable hood 3 are equipped with sound insulation layers 14. The fixed hood 2 and the movable hood 3 form a sealed space, which can control the diffusion of dust and noise. The added sound insulation layer 14 further reduces the noise generated by the operation of the internal equipment. Each movable hood 3 is fixed with a handle, making it easy to open.

[0030] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution will now be briefly explained in conjunction with specific application scenarios: In the closed state, the fixed cover 2 and the movable covers on both sides 3 form a sealed space, which confines the dust generated by the cleaner inside the cover. The connecting air duct 9 at the top of the dust collection cover is connected to the external dust removal system. Under the action of negative pressure, the dust in the sealed space is continuously sucked out to prevent the dust from overflowing.

[0031] When maintenance or observation is required, the operator first loosens the positioning screw 18 on the movable cover 3, slides the movable plate 17 to separate it from the limit plate 19, and then releases the lock. Then, the movable cover 3 is flipped outward and opened by using the handle, and the support rod 4 is removed from the slot of the locking block 6 and inserted into the slot of the insert block 5, providing stable support for the opened movable cover 3 and forming a safe operating space without the need to disassemble the cover as a whole.

[0032] During operation, the transparent panel 8 allows for easy observation of the internal workings of the equipment without the need for repeated opening and closing of the movable cover 3. If dust accumulation on the inner surface of the transparent panel 8 obstructs the view, the handle on the frame 10 can be rotated to drive the rotating shaft 11 and the rotating plate 12 to rotate, causing the scraper 13 to scrape the inner surface of the transparent panel 8 to remove the accumulated dust and maintain a clear view.

[0033] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
