Description

Technical Field

[0001] The utility model relates to the technical field of ore mining, in particular to a conveyor protection device used in mine mining. Background Art

[0002] Mining is a key resource acquisition activity in modern industry, involving a large amount of material handling and transportation. As one of the core equipment in mining, conveyors play a vital role in the handling of bulk materials such as ore and coal. With the development of the industrial revolution and the improvement of mechanization, conveyors have gradually replaced traditional transportation methods. Modern mining conveyor technology has evolved over the years, from the initial simple belt conveyors to today's efficient automated conveying systems. It not only achieves a higher load-bearing capacity in structure, but also has a higher level of intelligence in control and operation. These conveyors are generally designed for long-distance, continuous transportation, which can significantly improve the transportation efficiency of ore from the mining point to the processing point and reduce operating costs.

[0003] However, despite significant progress in the design and functionality of modern mining conveyors, some shortcomings remain that cannot be ignored, particularly when transporting ore from low to high locations. To prevent ore from falling, conveyor designs typically leave space on both sides. This prevents the conveyor from operating at full load during transportation, reducing overall transportation efficiency. Furthermore, most current conveyors lack effective protective devices, and the risk of ore falling still exists. This is especially true when workers are working beneath the conveyor, as falling ore can pose a serious safety threat to workers. For example, if ore falls during transportation due to vibration or tilting, it can not only damage the equipment but can also cause personal injury. Therefore, how to maximize the full-load operating capacity of conveyors while ensuring safety has become an urgent issue for the mining industry. Utility Model Content

[0026] Example

[0027] See also Figure 1-3 As shown, the utility model provides a technical solution for a conveyor protection device for mining: a conveyor protection device for mining, comprising a support 1 and a conveyor 2 on the support 1, and a protection mechanism 3 is provided at the lower end of the conveyor 2;

[0028] The protection mechanism 3 comprises a protection plate 301 and a speed reduction mechanism 302. The protection plate 301 is tilted and mounted at the lower end of the conveyor 2, with the tilt angle of the protection plate 301 increasing along the conveying direction. The width of the protection plate 301 is greater than the width of the conveyor 2. The speed reduction mechanism 302 is located at the upper end of the protection plate 301 and is used to slow the movement of falling ore within the protection plate 301. When the conveyor 2 is fully loaded, ore inside the conveyor belt may fall due to various reasons (such as uneven laying, vibration caused by the operation of the conveyor 2, or other external forces). If it falls, the protection plate 301 will intercept the ore to prevent it from posing a safety threat to the personnel below. Due to the inherent tilt of the protection plate 301, the falling ore will roll downward along the inner wall of the protection plate 301 and eventually be discharged at the end of the protection plate 301. As the ore rolls down, the speed reduction mechanism 302 provides a deceleration effect, preventing the ore from rolling downward due to its own gravity for a long time, thereby improving safety.

[0029] In a specific implementation process, a storage tank can be directly set at the end of the protection plate 301, and an elevator can be set in the tank to transport the rolled ore again, thereby improving work efficiency.

[0030] The deceleration mechanism 302 includes a deceleration plate 3021, which is rotatably mounted on the bracket 1. The deceleration plate 3021 is a lightweight plastic plate (such as a polyethylene plate, a polyurethane plate, a polypropylene plate, etc.). In the specific implementation process, the distance between the brackets 1 can be designed to be less than 5 meters, so as to achieve a better deceleration effect. Figure 2 As shown, when the ore rolls downward along the inner wall of the protective plate 301, the edge of the vertically downward deceleration plate 3021 will contact the ore. This contact will generate friction during the rolling of the ore, thereby offsetting part of the kinetic energy of the ore and effectively slowing down the rolling speed of the ore.

[0031] The protective plate 301 is an arc-shaped structure. This design can better guide the falling ore to roll along the predetermined path, reduce the irregular movement of the ore on the protective plate 301, thereby reducing the risk of lateral scattering of the ore, ensuring the deceleration effect of the ore during the falling process, and ensuring that the ore can smoothly roll down along the arc path and be discharged at the end. It also reduces the phenomenon of stagnation and improves the efficiency of ore discharge.

[0032] The middle portion of the protective plate 301 is provided with first deceleration stripes 4, and flanking these stripes are second deceleration stripes 5. By placing the first deceleration stripes 4 in the middle portion of the protective plate 301 and the second deceleration stripes 5 on its sides, the ore will make multiple contacts with these stripes during its tumbling process. This multi-point contact increases the ore's rolling resistance, further slowing its rolling speed and improving the overall deceleration effect. This design effectively reduces the kinetic energy of the ore as it rolls, minimizing its impact on the protective plate 301.

[0033] A support assembly 6 is mounted on the bracket 1, such as Figure 3 As shown, the support assembly 6 passes through the protective plate 301 and is connected to the main load-bearing part of the bracket 1 (that is, the part that mainly bears the weight of the conveyor 2). This design not only enhances the overall structural stability of the bracket 1, but also effectively improves the structural strength of the protective plate 301, ensuring that the protective plate 301 can remain stable and strong when subjected to ore impact.

[0034] The working principle of this utility model is as follows:

[0035] When a conveyor protection device for mining of this embodiment is in use, when the conveyor 2 is fully loaded with ore and ore on the inner side of the conveyor belt falls due to uneven laying, vibration caused by the operation of the conveyor 2, or other external forces, the ore will first contact the protection plate 301 provided at the lower end of the conveyor 2. Because the protection plate 301 is designed to be inclined and wider than the width of the conveyor 2, it can effectively intercept and guide the falling ore, preventing it from posing a safety threat to the workers below.

[0036] As the ore rolls downward along the inner sidewall of the protective plate 301, the vertically downward-facing deceleration plate 3021 contacts the edge of the ore, using the friction of its lightweight plastic sheet to offset some of the ore's kinetic energy, effectively slowing the ore's rolling speed. Furthermore, the curved structure of the protective plate 301 allows the ore to roll smoothly along a predetermined curved trajectory, minimizing irregular motion and the risk of lateral scattering, ultimately leading to discharge at the end of the protective plate 301.

[0037] When the ore is slowed down and accumulates at the end of the protective plate 301, the ore can be collected by a storage tank set at the end and transported back to the system by a hoist, further improving work efficiency and reducing material waste.

[0038] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention.
