[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a safety protection device for a mining belt conveyor, comprising a fixed frame, a plurality of connecting plates are fixedly connected to the side wall of the fixed frame, the upper surface of each connecting plate is rotatably connected to a rotating shaft, a bolt is threadedly connected to the inside of each connecting plate, and the outer wall of each bolt is threadedly connected to the inside of the fixed frame, a baffle is fixedly connected to the side wall of the fixed frame, a bottom plate is fixedly connected to the lower surface of the fixed frame, a fixed plate is fixedly connected to the upper surface of the bottom plate, a motor is arranged on the upper surface of the fixed plate, a roller is arranged at the output end of the motor, and a push-pull assembly is arranged on the side wall of the bottom plate.

[0013] The utility model has the following beneficial effects:

[0014] 1. In the utility model, firstly, the motor operates above the fixed plate to drive the roller above the base to rotate. The rotation of the roller can drive the conveyor belt on its surface to start transmission. Since the fixed frame is provided with multiple rotating shafts, the conveyor belt surface is not flat but curved during the process of conveying ore, so that the ore will not be easily leaked during transportation. Moreover, since each connecting plate is connected to the fixed frame by bolts, each rotating shaft can be disassembled separately for later maintenance.

[0015] 2. In the utility model, the push rod is driven to move by the cylinder, and the push rod pushes the connecting platform, so that the connecting rod 1 is pushed and rotates inside the connecting platform. While the connecting rod 1 moves, the inclination angle inside the fixed platform is changed, and the connecting rod 2 is pushed so that the inclination angle of the connecting rod 2 is also changed and slides relative to the conveying platform 1, so that the push column is pushed to push the ore inside the conveying platform 1 that exceeds the load level line into the conveying platform 2, thereby achieving the effect that the conveying device has double discharge ports, greatly reducing the possibility of blockage of the conveying device, and improving the ore transmission efficiency.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-2The utility model provides an embodiment: a safety protection device for a mining belt conveyor, comprising a fixed frame 1, a plurality of connecting plates 2 are fixedly connected to the side wall of the fixed frame 1, a rotating shaft 3 is rotatably connected to the upper surface of each connecting plate 2, a bolt 4 is threadedly connected to the inside of each connecting plate 2, and the outer wall of each bolt 4 is threadedly connected to the inside of the fixed frame 1, a baffle 5 is fixedly connected to the side wall of the fixed frame 1, a bottom plate 6 is fixedly connected to the lower surface of the fixed frame 1, a fixed plate 7 is fixedly connected to the upper surface of the bottom plate 6, a motor 8 is arranged on the upper surface of the fixed plate 7, a roller 9 is arranged at the output end of the motor 8, and a push-pull assembly is arranged on the side wall of the bottom plate 6.

[0023] Specifically, the start of the motor 8 causes the roller 9 to generate a rotating force, and the rotation of the roller 9 immediately drives the conveyor belt on its surface to start operating. Driven by the roller 9, the conveyor belt transports the ore. In this process, the conveyor belt not only transports the ore, but also produces a sliding effect on the surface of the rotating shaft 3. It is worth noting that the rotation method of the rotating shaft 3 on the side wall of the connecting plate 2 is that the connecting plate 2 is fixed on the side wall of the fixed frame 1 at an angle, which makes the conveyor belt present a curved surface rather than a flat surface when sliding on the surface of the rotating shaft 3. This design plays a key role in improving the stability of the ore during the transmission process. It effectively reduces the occurrence of side leakage and reduces the risk of accidents, thereby significantly improving the protective performance of this protective device for ore transmission. In addition, each connecting plate 2 is fixed to the fixed frame 1 by bolts 4. This design makes the disassembly of the connecting plate 2 simple and quick, greatly improves the maintenance efficiency of this protective structure, and ensures the long-term operation of the equipment.

[0024] Reference Figure 3 The push-pull assembly includes a support platform 10, the side walls of the support platform 10 are fixedly connected to the side walls of the bottom plate 6, the upper surface of the support platform 10 is fixedly connected to a conveying platform 11, the side walls of the conveying platform 11 are fixedly connected to a conveying platform 2 12, the side walls of the push rod 14 are fixedly connected to a connecting platform 15, the inside of the connecting platform 15 is rotatably connected to a connecting rod 16, one end of the connecting rod 16 is rotatably connected to a connecting rod 2 17, the upper surface of the support platform 10 is fixedly connected to a fixed platform 18, the side walls of the connecting rod 16 are rotatably connected to the inside of the fixed platform 18, and one end of the connecting rod 2 17 is fixedly connected to a push column 19.

[0025] Specifically, during the ore conveying process, when the ore is completed, we need to discharge it. In order to achieve this goal, the ore will first be conveyed into the conveying platform 11. The conveying platform 11 is an important device, which is responsible for receiving and temporarily storing the ore. At this time, the cylinder 13 starts to operate and pushes the push rod 14. The design of the push rod 14 is very clever. It can push the connecting platform 15 at the same time. The connecting platform 15 is a bridge connecting two conveying platforms. Its movement means that the ore can be smoothly transferred from the conveying platform 11 to another conveying platform. While the connecting platform 15 moves, the connecting rod 16 inside it also rotates and changes the inclination angle. The purpose of this action is to adjust the position of the ore and ensure that the ore can be stably transmitted to the next The fixed platform 18 plays a vital role in the conveying platform. It limits the connecting rod 16 to ensure that it will not flip over during the movement, which means that the transmission process of the ore is more stable and will not tip over or scatter due to the movement of the equipment. By changing the inclination angle of the connecting rod 16, we can further change the inclination angle of the connecting rod 2 17. This action directly affects the direction and strength of the push column 19. The function of the push column 19 is to push the ore accumulated inside the conveying platform 11 into the conveying platform 2 12. This structure realizes the effect of double discharging. This design greatly improves the conveying efficiency of the ore and reduces the possibility of blockage. This not only improves the mining efficiency of the ore, but also reduces the time and cost waste caused by blockage.

[0026] Working principle: When transporting ore, first install the conveyor belt in this device, then turn on the motor 8, so that the motor 8 outputs a rotating force to the roller 9. When the roller 9 rotates, it can drive the conveyor belt on its surface to start operating and transport the ore. When the conveyor belt moves, it will slide on the surface of the rotating shaft 3, so that the rotating shaft 3 rotates on the side wall of the connecting plate 2. Since the connecting plate 2 is fixed on the side wall of the fixed frame 1 at an angle, the conveyor belt is in a curved state rather than a flat surface when sliding on the surface of the rotating shaft 3. This can ensure the stability of the ore during transportation, make it less likely to leak, reduce the possibility of accidents, and improve the protective performance of this protective device for ore transportation. In addition, since each connecting plate 2 is fixed in the fixed frame 1 by bolts 4, the individual disassembly of the connecting plate 2 is easy. It becomes simple and convenient, and improves the maintenance efficiency of this protective structure. When the ore is transported and needs to be discharged, the ore will first be transported into the conveying platform 11. At this time, the cylinder 13 operates to push the push rod 14, so that the push rod 14 pushes the connecting platform 15 at the same time. When the connecting platform 15 moves, it drives the connecting rod 16 inside it to rotate and change the inclination angle. The fixed platform 18 limits the connecting rod 16 so that it will not flip while moving. The change in the inclination angle of the connecting rod 16 can change the inclination angle of the connecting rod 2 17, thereby pushing and pulling the push column 19, and pushing the ore accumulated inside the conveying platform 11 into the conveying platform 2 12. The structure achieves double discharge, so that blockage will not easily occur during the ore transmission process, and the efficiency of ore mining is improved.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
