Description

Technical Field

[0001] The invention relates to the technical field of ore lifting and conveying, in particular to a lifting device used in ore mining. Background Art

[0002] The existing lifting device for ore mining consists of a conveyor belt, a roller, a transmission device, an idler, a support frame, etc. The conveyor belt is usually made of materials such as rubber or polyester fiber, which has a certain toughness and tensile strength; the conveyor belt drives the ore to be transported along a specific path through the rotation of the roller.

[0003] However, some ores are not crushed and are large in size, which causes serious local wear of the conveyor belt and affects the practical life of the conveyor belt. When the top of the ore pile is transported to a high place with the conveyor belt, there is a risk of rolling down under the influence of gravity. In addition, the conveyor belt is prone to deviation during operation, which affects the transmission effect and may even cause ore to leak from both sides of the conveyor belt. Summary of the invention

[0030] Embodiment 1

[0031] Combined with Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A lifting device for ore mining includes a bracket 1, one end of the bracket 1 is connected to a motor 2, the power output end of the motor 2 is connected to a driving shaft, the driving shaft rotates and passes through the bracket 1 and is connected to a driving roller 3, the other end of the bracket 1 is rotatably connected to a driven shaft, the driven shaft is connected to a driven roller 4, a conveyor belt 5 is connected between the driven roller 4 and the driving roller 3, the bracket 1 is connected to a side close to the driving roller 3 with a crushing cover 6 with an open bottom end, the top of the crushing cover 6 is connected to a feed port 7, and the crushing cover 6 rotates on both sides below the feed port 7 A crushing roller 8 is connected, and a driven driving assembly that can drive the crushing roller 8 to rotate relatively is connected to the crushing roller 8. The driven driving assembly includes a first synchronous wheel 12 connected to the driving shaft and extending from one end of the bracket 1. A rotating shaft that is rotatably connected to the bracket 1 is connected inside the crushing roller 8. A second synchronous wheel 13 and a gear 14 are connected to the rotating shaft on one side. The second synchronous wheel 13 is connected to the first synchronous wheel 12 through a synchronous belt. A gear 2 15 is connected to the rotating shaft on the other side. The gear 2 15 is meshed with the gear 14. A discharging port 9 is connected to the crushing cover 6 near the driven roller 4.

[0032] The motor 2 in the above structure drives the active roller 3, which cooperates with the driven roller 4 to drive the conveyor belt 5, so that the ore can be conveniently conveyed from one end of the bracket 1 to the other end of the bracket 1 through the conveyor belt 5; at the same time, the motor 2 drives the two crushing rollers 8 in the crushing cover 6 to rotate relative to each other through the driven drive component, so as to facilitate the crushing operation of the ore introduced into the feed port 7, avoid the inconvenience of transportation due to the large volume of the ore, and avoid the safety risks caused by the falling of large ores during the lifting process.

[0033] Combined with Figure 5 The crushing cover 6 is connected to the discharge port 9 with a rake assembly that can flatten the accumulated ore. The rake assembly includes a baffle 16 at the discharge port 9 hinged by a torsion spring, and the height of the baffle 16 is less than the height of the discharge port 9;

[0034] The arrangement of the raking assembly in the above structure facilitates the leveling of the ore pile discharged through the discharge port 9, thereby avoiding the safety risks caused by excessive ore accumulation and local damage to the support wheels.

[0035] Combined with Figure 1 and Figure 4 The bracket 1 is a V-shaped structure.

The coordinated arrangement of the guide roller 17, the connecting plate and the guide wheel 18 facilitates the guidance of the conveyor belt 5, and the gap arrangement prevents the guide wheel 18 from blocking the ore.

[0037] Embodiment 2

[0038] Based on the first embodiment, combined with the attached Figure 6 and Figure 7 A plurality of support rollers 10 are rotatably connected on the bracket 1, a fixed plate 23 is connected relative to the bracket 1, and side plates 24 are respectively connected on both sides of the fixed plate 23. The support rollers 10 are rotatably connected relative to the side plates 24, and the upper surfaces of the support rollers 10 abut against the conveyor belt 5. The bracket 1 is rotatably connected with inclined rollers 11 on both sides of the support rollers 10, and a fixed plate 23 is connected relative to the bracket 1. Side plates 24 are respectively connected on both sides of the fixed plate 23, and the support rollers 10 are rotatably connected relative to the side plates 24, and the upper surfaces of the support rollers 10 abut against the conveyor belt 5.

[0039] The arrangement of the support rollers 10 facilitates stable support for the ore and improves the supporting strength of the conveyor belt 5 for the ore.

[0040] Combined with Figure 7 and Figure 8 The tilted roller 11 is connected with an angle adjustment component that can drive the tilted roller 11 to adjust the angle. The angle adjustment component includes a connecting shaft 25 on the outside of a hinged side plate 24. The tilted roller 11 is rotatably connected to the connecting shaft 25. The other end of the connecting shaft 25 is hinged with an armature 26. The other end of the armature 26 is hinged with a threaded rod 27. A support plate 29 is connected to the outside of the bracket 1. A threaded cylinder 28 is rotatably connected to the support plate 29. The threaded rod 27 penetrates the support plate 29 and penetrates the threaded cylinder 28 through a thread.

[0041] The arrangement of the inclined roller 11 and the angle adjustment assembly facilitates the adjustment of the angle of the inclined roller 11, and facilitates the transfer of ore on both sides of the conveyor belt 5 to the middle, thereby avoiding safety risks caused by ore leakage from both sides of the conveyor belt 5.

[0042] Embodiment 3

[0043] Based on the second embodiment, combined with the attached Figure 1The driving roller 3, the guide roller 17 and the driven roller 4 are respectively connected with a first annular groove 19 in the middle, and a gear 20 is connected to the first annular groove 19. A gear ring 21 is connected to the conveyor belt 5, and the gear ring 21 meshes with the gear 20. A second annular groove 22 is connected to the supporting roller 10, and the second annular groove 22 cooperates with the gear ring 21.

[0044] The coordination of the first annular groove 19, the gear three 20 and the gear ring 21 facilitates the positioning of the conveyor belt 5 to prevent the conveyor belt 5 from shifting during the conveying process. The second annular groove 22 cooperates with the gear ring 21 to prevent the support roller 10 from interfering with the gear ring 21 during the movement of the conveyor belt 5.

[0045] The specific usage is as follows:

[0046] First, start the motor 2, which drives the active roller 3 through the driving shaft, thereby driving the conveyor belt 5 to move back and forth between the active roller 3 and the driven roller 4, so as to facilitate the conveyance of the ore from one end of the support 1 to the other end of the support 1;

[0047] At the same time, the motor 2 drives the first synchronous wheel 12 through the driving shaft, and the first synchronous wheel 12 drives the crushing roller 8 on one side of the rotating shaft to rotate through the synchronous belt, and the rotating shaft on one side drives the rotating shaft and the crushing roller 8 on the other side to rotate in the opposite direction through the meshing of the gear 14 and the gear 2 15, thereby facilitating the crushing operation of the ore and reducing the probability of the ore rolling down due to its excessive volume;

[0048] The crushed ore is guided out of the discharge port 9 through the conveyor belt 5. The raking assembly is provided to facilitate the flattening of the ore pile guided out of the discharge port 9, thereby avoiding the safety risk and local damage to the support wheel caused by the excessive accumulation of ore. When the ore is guided out of the discharge port 9 through the conveyor belt 5, the ore that is higher than the lower surface of the baffle 16 will be blocked by the baffle 16. As the ore is conveyed, the torsion spring on the baffle 16 is deformed. At this time, some ores that are not tightly stacked are swept into the crushing cover 6 by the action of the baffle 16, thereby avoiding the ore from being rigidly stuck at the discharge port 9. When there is no ore that exceeds the lower surface of the baffle 16, the baffle 16 is reset under the reset action of the torsion spring.

[0049] When it is found that the ore is easy to leak out from the two sides of the conveyor belt 5, the threaded cylinder 28 can be rotated. The threaded cylinder 28 drives the threaded rod 27 by cooperating with the thread of the threaded rod 27. Since the threaded rod 27 is hinged, the threaded rod 27 cannot rotate, so that the threaded rod 27 can only be raised and lowered. The threaded rod 27 drives the connecting shaft 25 through the armature 26 to drive the inclined roller 11 to change its angle, thereby facilitating the adjustment of the height of the two sides of the conveyor belt 5, and conveniently transferring the ore on both sides of the conveyor belt 5 to the middle, avoiding the ore from leaking from the two sides of the conveyor belt 5.
