Detailed Implementation

[0026] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0027] To achieve the above-mentioned technical features, the purpose of this utility model is as follows:

[0028] See appendix Figure 1-7 A belt conveyor return material cleaning device includes a slag discharge roller 1 and a cleaning mechanism 2. The slag discharge roller 1 includes a first rotating shaft 12 mounted below the return belt 3 of the head 4 of the belt conveyor via a mounting base 11. Two web plates 13 are mounted parallel to each other along the axial direction on the first rotating shaft 12. A plurality of scraper bars 14 are provided between the two web plates 13. The plurality of scraper bars 14 are evenly distributed along the circumference of the web plates 13 and form a cylindrical structure. A discharge gap 15 is provided between two adjacent scraper bars 14. The scraper bars 14 on the slag discharge roller 1 near the belt 3 abut against the return belt surface of the belt 3. The cleaning mechanism 2 is installed below the return belt surface of the belt 3 and is used to collect the material that falls off the return belt surface of the belt 3.

[0029] This utility model device includes a slag discharge roller 1 and a cleaning mechanism 2. During installation, the slag discharge roller 1 is installed below the return belt 3 of the head 4 of a belt conveyor. The belt tension of the belt is adjusted so that the scraper bars 14 on the slag discharge roller 1 abut against the belt 3 under tension. During operation, as the belt conveyor runs, the material adhering to the return belt surface of the belt 3 is squeezed into the discharge gap 15 between the two scraper bars 14 under the pressure of the belt. It then passes through the slag discharge roller 1 and falls into the cleaning mechanism 2. The cleaning mechanism 2 then directionally cleans the material that has fallen off the return belt surface into the funnel 41 at the head 4 of the belt conveyor, completing the collection. With the slag discharge roller 1, no additional power is required to effectively remove material adhering to the belt surface. Combined with the operation of the cleaning mechanism 2, automatic material collection is achieved.

[0030] In one embodiment, this application further includes an idler roller 5 mounted below the return surface of the conveyor belt 3 via a bearing seat. The circumference of the idler roller 5 is provided with a spiral protrusion 51 that abuts against the return surface of the conveyor belt 3. The slag discharge roller 1 is located between the idler roller 5 and the head 4 of the belt conveyor. The spiral protrusion 51 is provided to further remove stubborn adhering materials on the return surface, and the removed adhering materials fall into the cleaning mechanism 2 below the return surface of the conveyor belt 3 for cleaning.

[0031] In one embodiment, a spindle structure 16, which is smaller at both ends and larger in the middle, is installed on the first rotating shaft 12. The spindle structure 16 is located inside the cylindrical structure. During operation, the material attached to the return surface of the conveyor belt 3 is squeezed into the discharge gap 15 between the two scraper bars 14 under the pressure of the conveyor belt 3, and then falls onto the outer surface of the spindle structure 16 and gradually slides outward to both sides. Subsequently, it is discharged from the discharge gap 15 between the scraper bars 14 at the bottom of the slag discharge roller 1. The spindle structure 16 is designed to disperse the material from the slag discharge roller 1, thereby improving the discharge efficiency and avoiding repeated pressure and wear on the conveyor belt caused by material accumulation, thus effectively improving the service life of the conveyor belt.

[0032] In one embodiment, the scraper rod 14 is made of round steel. Multiple positioning grooves 131 for cooperating with the scraper rod 14 are evenly provided along the circumference of the web plate 13. The scraper rod 14 is connected and fixed to the web plate 13 by welding. This structure is simple and reliable, facilitating the manufacture of the slag discharge roller 1. During operation, the circumferential arc of the scraper rod made of round steel contacts the conveyor belt. On the one hand, the arc surface contact avoids scratching the conveyor belt by its edges, extending the service life of the conveyor belt. On the other hand, the scraper rod and the adhesive surface of the conveyor belt form a relatively small contact area, increasing the contact stress between them and indirectly improving the slag removal efficiency.

[0033] In one embodiment, the plate 13 is provided with a plurality of discharge holes 132, which facilitates the discharge of materials from the slag discharge roller 1 and also reduces the weight of the holes.

[0034] In one embodiment, the cleaning mechanism 2 includes a receiving trough 21 installed below the return surface of the conveyor belt 3, and a material conveying component is installed in the receiving trough 21. The receiving trough 21 facilitates the collection of material falling off the return surface, and the material conveying component directs the material into the funnel 41 at the head of the belt conveyor 4. The material conveying component can be one of a screw conveyor, a belt conveyor, or a scraper conveyor.

[0035] In one embodiment, the material conveying component includes second rotating shafts 22 installed at both ends of the receiving trough 21. Each second rotating shaft 22 has a sprocket 23 installed at both ends. The sprockets 23 on the same side of the two second rotating shafts are connected by annular chains 24. A scraper 25 is provided between the two annular chains 24. The second rotating shaft 22 at one end of the receiving trough 21 is connected to the output shaft of the motor 26. During operation, material falling off the return belt surface into the receiving trough 21 is driven by the motor to rotate the sprockets and annular chains 24, thereby driving the scraper 25 to transfer the material in the receiving trough 21 into the funnel 41 at the head of the belt conveyor 4.
