[0002] Belt conveyors have the advantages of large conveying capacity, simple structure, easy maintenance, and standardized components. They are widely used in mining, metallurgy, coal and other industries to convey loose materials or pieced items. According to the conveying process requirements, they can be transported by a single unit or multiple units can be combined to form a horizontal or inclined conveying system to meet the needs of different layout types of work lines.

[0003] At present, the belt conveyors used in the mining, coal and other industries are set to a horizontal or inclined state. In the process of conveying materials, in order to prevent the materials from falling scattered, a guide bucket is usually set at the terminal of the conveyor.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] like Figure 1 As shown, a preferred embodiment of the present invention provides an auxiliary unloading device for a belt conveyor, which includes a bracket, a slide bar 1, a reciprocating drive unit, a scraper assembly and a rotating plate 2.

[0029] The bracket includes two support plates (not shown in the figure) arranged opposite to each other and a cross plate 3 connecting the two support plates, and the connection is fixed by welding. A through hole is provided in the middle of the cross plate 3, and the slide bar 1 passes through the through hole and can slide along the length direction of the slide bar 1, that is, the front-back direction.

[0030] like Figure 2 As shown, the reciprocating drive unit includes a mouth-shaped frame 4, which is surrounded by a front side plate, an upper side plate, a rear side plate and a lower side plate. The front side plate is vertically fixedly connected to one end of the slide bar 1, that is, the rear end of the slide bar 1. The inner wall of the upper side plate and the inner wall of the lower side plate are both installed with a toothed plate 5, and the toothed plate 5 is arranged along the front-back direction. The left and right sides of the mouth-shaped frame 4 are respectively provided with mounting plates 6, and the two mounting plates 6 are symmetrically arranged and vertically fixedly connected to the rear side of the cross plate 3. A transmission shaft 7 is rotatably installed between the two mounting plates 6. Specifically, the two ends of the transmission shaft 7 are rotatably connected to the corresponding mounting plates 6 through bearings, and the transmission shaft 7 passes through the mouth-shaped frame 4. A residual gear 8 is fixedly installed on the transmission shaft 7. The residual gear 8 is about one-third of the full gear. The residual gear 8 is meshed with the upper and lower toothed plates 5, which can realize that the transmission shaft 7 drives the residual gear 8 to rotate and drives the mouth-shaped frame 4 and the slide bar 1 to reciprocate synchronously. A driving motor 9 is installed on any one of the mounting plates 6 , and an output end of the driving motor 9 is drivingly connected to the transmission shaft 7 .

[0031] Furthermore, a guide post 10 is provided on the left and right sides of the slide bar 1, each guide post 10 is parallel to the slide bar 1 and vertically fixedly connected to the front side of the cross plate 3, and connecting rods 11 are vertically connected to the left and right sides of the slide bar 1, and a sleeve is provided at the end of each connecting rod 11, and the sleeve can be slidably mounted on the corresponding guide post 10. The above arrangement ensures that the slide bar 1 reciprocates along the linear front and back.

[0032] like Figure 3 As shown, the scraper assembly includes a box-shaped housing 12 with an open top, and the box-shaped housing 12 is fixedly installed at the other end of the slide bar 1, that is, the front end top surface of the slide bar 1. Two springs 13 are fixedly installed in the box-shaped housing 12, and a lifting plate 14 is fixedly connected between the top ends of the two springs 13. A scraper 15 is fixedly installed on the lifting plate 14. The scraper 15 is arranged along the left and right directions, and a plurality of strip holes 16 are arranged at intervals on the scraper 15. The plurality of strip holes 16 are distributed in a linear array, and the plurality of strip holes 16 are provided for scraping off debris on the conveyor belt 17.

[0033] like Figure 4As shown, one side of the rotating plate 2 is mounted on the bracket so as to be rotatable up and down through the rotating shaft 18. Specifically, the rotating plate 2 is located on the front side of the cross plate 3 and below the slide bar 1. The rotating shaft 18 is located between the two support plates, and the two ends of the rotating shaft 18 are rotatably connected to the corresponding support plates. A plurality of L-shaped top support plates 19 are fixedly provided on the opposite side of the rotating plate 2, and the L-shaped top support plates 19 extend forward and upward, and the plurality of L-shaped top support plates 19 are distributed in a linear array on the rotating plate 2. A gear 20 is fixedly mounted on the rotating shaft 18. In order to facilitate the installation of the gear 20, a notch 21 is provided in the middle position of one side of the rotating plate 2 where the rotating shaft 18 is installed. The gear 20 is located in the notch 21. A rack 22 is fixedly mounted on the bottom surface of the slide bar 1 along the front-to-back direction, and the rack 22 is meshed and connected with the gear 20.

[0034] When the slide bar 1 reciprocates forward and backward, the engagement between the rack 22 and the gear 20 can drive the rotating plate 2 and the L-shaped supporting plate 19 to rotate up and down synchronously.

[0035] The device of this embodiment is installed at the terminal position of the belt conveyor 23, specifically below the conveyor belt 17, and makes the scraper 15 contact the conveyor belt 17. Due to the action of the spring 13, the scraper 15 can be supported on the conveyor belt 17. At the same time, the L-shaped support plate 19 extends to the front side of the terminal of the belt conveyor 23, referring to Figure 5-Figure 6 , used for auxiliary unloading, the specific working principle is as follows:

[0036] The driving motor 9 is started and drives the slide bar 1 to slide back and forth, thereby driving the scraper 15 to slide back and forth, so that the scraper 15 can scrape off the debris on the conveyor belt 17 to prevent the conveyor belt 17 from being adhered to a large amount of debris during the long-term material conveying process, resulting in poor conveying. The setting of the two springs 13 will always apply an upward force to the scraper 15, so that the scraper 15 always maintains a full fit with the conveyor belt 17, increasing the force for scraping off the debris.

[0037] At the same time, during the reciprocating sliding of the slide bar 1, the turn plate 2 is driven to rotate reciprocatingly up and down, so that the multiple L-shaped top support plates 19 are continuously rising and falling at the front side of the terminal of the belt conveyor 23, thereby achieving a dredging effect, avoiding material jamming between the belt conveyor 23 and the inner wall of the guide bucket, reducing the wear on the conveyor belt 17 after the material is jammed, and further improving the protection of the conveyor belt 17.

[0038] In summary, in the process of using the belt conveyor 23 to transport materials, the auxiliary unloading device for a belt conveyor described in an embodiment of the present invention drives the slide bar 1 to slide back and forth through the driving motor 9, so that the scraper 15 scrapes and clears the debris on the conveyor belt 17. At the same time, multiple L-shaped top support plates 19 are continuously rising and falling at the front side of the terminal of the belt conveyor 23, avoiding the material from being stuck between the belt conveyor 23 and the inner wall of the guide bucket, thereby maintaining the smoothness of the material transmission process and avoiding damage to the conveyor belt.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
