[0020] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0021] refer to Figure 1 and Figure 2 This application provides a dust-proof roller cleaner for cleaning dust adhering to the surface of a conveyor belt, wherein a mounting steel beam 12 is provided above the conveyor belt 11. The dust-proof roller cleaner includes a cleaning component and a dust-proof component. The cleaning component includes a mounting frame, an upper roller 22, and a lower roller 23, wherein the mounting frame includes mounting plates 21 parallel and symmetrically distributed on both sides of the conveyor belt, and the top of the mounting plates 21 is fixedly connected to the mounting steel beam 12. The surfaces of the upper roller 22 and the lower roller 23 are provided with brushes for cleaning the conveyor belt 11, and the upper roller 22 and the lower roller 23 are rotatably mounted between the two mounting plates 21 so as to synchronously clean the material adhering to the upper and lower surfaces of the conveyor belt 11 when the conveyor belt 11 moves.

[0022] The dustproof assembly includes a dust cover 31 and a connecting frame 32. The connecting frame 32 is located on both sides of the conveyor belt 11 in the conveying direction. The dust cover 31 is located below the lower roller 23 and is connected to the mounting steel beam 12 through the connecting frame 32. The dust cover 31 has clearance notches 301 on both sides that cooperate with the mounting plate 21, and the bottom of the dust cover 31 has a material discharge port (not shown in the figure). Thus, the dust cover 31 can collect the materials and dust swept down from the upper roller 22 and lower roller 23 on the upper and lower surfaces of the conveyor belt 11 in a timely manner. The collected materials and dust finally fall through the material discharge port of the dust cover 31, which can reduce dust in the tunnel and is beneficial to the physical and mental health of the workers working in the tunnel.

[0023] In actual installation, the dust-proof roller cleaner can be installed at key positions at the head, tail, or middle of the conveyor belt 11. The head installation can clean the residual material on the surface of the conveyor belt 11 after unloading, the tail installation helps to remove the accumulated material on the return belt, and the middle installation can prevent material from falling and accumulating during the operation of the conveyor belt 11.

[0024] In addition, during installation, it is necessary to ensure that the upper roller 22 and the lower roller 23 can rotate flexibly, and the length of the upper roller 22 and the lower roller 23 must match the width of the conveyor belt 11. The rollers should not be too short, which would result in incomplete cleaning, or too long, which would affect the operation of other equipment.

[0025] In one embodiment, bearings are installed in the mounting plate 21 corresponding to the upper roller 22 and the lower roller 23, wherein the bearing near the bottom is a movable bearing. The upper roller 22 and the lower roller 23 are respectively provided with a central rotating shaft 24 that cooperates with the bearing. The mounting plate 21 has a micro-notch 201 at the movable bearing. The micro-notch 201 extends along the direction of the connecting line between the upper roller 22 and the lower roller 23. At the same time, an adjusting screw is installed at the bottom of the mounting plate 21, and the adjusting screw is facing the movable bearing. It is used to finely adjust the height of the movable bearing, that is, change the distance between the upper roller 22 and the lower roller 23, so that the brushes on the upper roller 22 and the lower roller 23 can be closely attached to the surface of the conveyor belt 11 to achieve a good cleaning purpose. However, it should not be too tight to avoid excessive wear on the conveyor belt 11. The adjusting screw can also be called a reverse screw. The micro-notch 201 is generally only a few microns in size and is not easily shown clearly in the figure.

[0026] In one embodiment, the top end of the mounting plate 21 is detachably connected to the mounting steel beam 12 via a connecting block 25, a connecting stud 26, and a fixing plate 27. The connecting block 25 is located between the mounting steel beam 12 and the mounting plate 21, and the fixing plate 27 is located at the top of the mounting steel beam 12. The connecting stud 26 vertically connects the fixing plate 27 and the connecting block 25 to both sides of the mounting steel beam 12. This detachable connection method facilitates the installation and maintenance of the dust-proof roller sweeper.

[0027] In one embodiment, the connecting frame 32 includes two fixed sleeves 321, two adjusting rods 322, and two adjusting nuts 323. The two fixed sleeves 321 are fixed (e.g., welded) vertically to the mounting steel beam 12. The two adjusting rods 322 are respectively disposed within the two fixed sleeves 321. Each adjusting rod 322 includes a lead screw 3221 near the upper part and a shaped rod 3222 near the middle and lower parts. The fixed sleeves 321 are provided with shaped channels that slide with the shaped rods 3222, thereby guiding the shaped rods 3222 through the fixed sleeves 321. The lead screw 322... The diameter of rod 1 is smaller than that of the irregular rod 3222, and the top of the fixing sleeve 321 is provided with a cover plate 3211 that is clearance-fitted with the lead screw 3221. At the same time, the two adjusting nuts 323 are respectively threaded with the two lead screws 3221, and the outer diameter of the adjusting nuts 323 is larger than the diameter of the hole on the cover plate 3211. In this way, the height of the dust cover 31 can be adjusted by rotating the four adjusting nuts 323 simultaneously, which facilitates the quick and accurate installation of the sweeper and meets different on-site installation conditions. It is easy to use. The irregular rod 3222 is preferably a square rod, and correspondingly, the fixing sleeve 321 is a square sleeve.

[0028] In one embodiment, the mounting plate 21 extends obliquely in the vertical direction, while the upper roller 22 and the lower roller 23 are respectively installed on the upper and lower parts of the mounting plate 21 and are staggered in the vertical direction. This can avoid the normal operation of the conveyor belt 11 being affected by the close fit between the upper roller 22 and the lower roller 23 and the conveyor belt 11.

[0029] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made to the implementation of the present invention without departing from the stated principles.
