Description

Technical Field

[0001] This utility model belongs to the technical field of mining machinery and equipment, and specifically relates to a conveying device for mining operations. Background Technology

[0002] In mining operations, material transport is a crucial step. Traditional conveying systems typically rely on conveyor belts to move materials from one location to another. However, due to the harsh mining environment, conveyor belt surfaces often accumulate significant amounts of dust and ore debris. These residues not only negatively impact the normal operation of the conveying system but also cause wear on the conveyor belt and other contact components, reducing the system's lifespan. Therefore, current conveying systems are often designed with scraper assemblies to remove residual material from the conveyor belt surface. However, existing scraper assemblies have the following drawbacks in practical operation:

[0003] First, the pressure between the scraper and the conveyor belt is uncontrollable, easily leading to damage to the scraper due to excessive friction or external impact during high-intensity operation, resulting in poor cleaning performance and frequent maintenance. Furthermore, when the scraper removes residual material from the conveyor belt surface, the friction between the scraper and the belt surface is difficult to adjust, potentially resulting in incomplete removal of material or damage to the conveyor belt. This situation is particularly pronounced in the conveying of highly adhesive materials such as ores and coal. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide a conveying device for mining operations. This device can achieve automatic adjustment of the scraper's position when the material pressure changes by setting an elastic reset mechanism and a guiding structure in the scraper assembly, thus avoiding scraper damage caused by excessive compression. At the same time, it can achieve multiple removals of residues on the conveyor belt surface, thereby improving the service life and cleaning efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A conveying device for mining includes a support frame, wherein idlers are evenly spaced along the length of the upper end face of the support frame;

[0007] Furthermore, a drive roller is provided at one end of the bracket, and a drive motor for driving the drive roller to rotate is provided on the outer side of one end of the bracket.

[0008] The support frame is equipped with a conveyor belt for conveying materials; when the drive roller rotates, it drives the conveyor belt to rotate synchronously.

[0009] A scraping assembly for residual material on the conveyor belt surface is provided below one end of the bracket.

[0010] Furthermore, the scraping assembly includes symmetrically arranged support corner pieces, one end of which is connected to a bracket, and a guide post is connected to the support corner piece. A connector and a spring are sleeved on the guide post, and the spring is located between the support corner piece and the connector.

[0011] A scraper is connected to the upper end face of the connector;

[0012] The movable end of the scraper is attached to the surface of the conveyor belt.

[0013] Furthermore, the movable end of the scraper is tangent to the outer surface of the drive roller.

[0014] Furthermore, the supporting corner piece is Z-shaped, and the guide post and the supporting corner piece are connected by a thread.

[0015] Furthermore, the connector is L-shaped, with a guide post passing through it, and one end of the guide post is fixedly connected to a disc for defining its position.

[0016] Furthermore, a material unloading rack is provided above the other end of the bracket;

[0017] The unloading rack includes two parallel crossbeams, and inclined plates are arranged opposite each other on the inner sides of the two crossbeams, with the inclined plates being inclined.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] First, the evenly spaced idlers on the support frame of this device provide effective support for the conveyor belt, preventing it from sagging and deforming when carrying heavy loads, thus ensuring the stability of the material during transportation. The cooperation between the drive roller and the drive motor ensures the smooth operation of the conveyor belt, maintaining high conveying efficiency even when transporting heavier materials such as ore, meeting the material transportation needs of mining sites.

[0020] Secondly, the scraping assembly, through its combined structure of supporting corner pieces, guide posts, springs, connectors, and scrapers, solves the problem of frequent scraper damage in existing technologies. Specifically, the scraper, through the axial movement of the guide posts and the elastic return function of the springs, automatically adjusts its position when removing residue from the conveyor belt surface. When the material's adhesion is strong, the scraper will retract towards the guide posts under pressure, preventing excessive compression and damage during cleaning. The springs ensure that the scraper returns to its original position promptly after material passes, thus achieving multiple cleaning cycles, improving cleaning efficiency, and ensuring that the conveyor belt surface remains clean throughout continuous operation.

[0021] Furthermore, the guide post and support bracket in the scraper assembly are connected by threads, ensuring the stability of the guide post and allowing the scraper to move in a fixed direction under different pressure conditions without shifting due to changes in external force. The Z-shaped structure design of the support bracket not only enhances the overall strength of the scraper assembly but also effectively improves the impact resistance and stability of the device during operation, thereby extending the service life of the scraper assembly and reducing the frequency of device maintenance.

[0022] Furthermore, the unloading rack simplifies the material feeding process. Two parallel beams and an inclined plate structure allow materials to slide naturally onto the conveyor belt without the need for additional pushing devices. This design effectively reduces the risk of material accumulation and jamming, ensuring the continuous and efficient operation of the conveyor system. Attached Figure Description

[0035] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0036] See Figure 1-4 A conveying device for mining operations includes a support frame 1. Multiple idlers 11 are evenly spaced along the length of the upper surface of the support frame 1. The uniform arrangement of the idlers 11 not only provides stable support for the conveyor belt but also effectively reduces the sagging deformation of the conveyor belt when carrying heavy objects such as ore, thus ensuring the stability and durability of the conveying device. A drive roller 2 is provided at one end of the support frame 1, which drives the conveyor belt to continuously convey materials along the length of the support frame 1. A drive motor 3 is connected to the outside of the drive roller 2 to drive its rotation. The drive motor 3 provides stable and powerful rotational force to the drive roller 2 through electric drive, ensuring that the conveyor belt can maintain stable operation under load conditions. A conveyor belt for conveying materials is provided on the support frame 1, arranged along the length of the idlers 11, and capable of carrying various ores or other materials fed in from the feed port. When the drive roller 2 rotates, it drives the conveyor belt to rotate synchronously, realizing continuous material conveying on the conveyor belt. A scraper assembly 5 for removing residual materials from the surface of the conveyor belt is provided below one end of the support frame 1.

[0037] See Figure 3-4 The scraping assembly 5 includes symmetrically arranged support corner pieces 51. The structure of the support corner pieces 51 is designed to provide stable support for the scraper 55, ensuring that the scraper 55 can always maintain a stable position when removing residual material from the conveyor belt. One end of the support corner piece 51 is connected to the bracket 1, and the position of the support corner piece 51 is fixed by a strong connection to prevent the scraping assembly from shifting or loosening during the operation of the conveyor belt, which would affect the cleaning effect. A guide post 52 is connected to the support corner piece 51. The guide post 52 passes through the support corner piece 51 and is kept vertical, ensuring that the scraper 55 is stable under external force. The scraper 55 can move linearly along the axis of the guide post 52, thereby automatically adjusting its position and avoiding damage caused by excessive squeezing. The guide post 52 is fitted with a connector 54 and a spring 53. The spring 53 is located between the support corner piece 51 and the connector 54. The spring 53 ensures that the scraper 55 can quickly return to its original position after the external force is removed through its elastic adjustment function, maintaining the consistency and stability of the cleaning effect. The upper end face of the connector 54 is connected to the scraper 55. Under the action of the connector 54, the scraper 55 is always in close contact with the surface of the conveyor belt, ensuring that the residual material on the conveyor belt is fully scraped off.

[0038] See Figure 3 The movable end of the scraper 55 is tangent to the outer side of the drive roller 2, and the scraper 55 maintains an appropriate frictional contact position with the surface of the conveyor belt, so that the scraper 55 can efficiently clean the residual material on the conveyor belt, while avoiding excessive friction between the scraper and the conveyor belt and causing wear. This tangential arrangement improves the cleaning efficiency of the scraper, especially in the process of conveying highly adhesive materials, ensuring that the material is completely removed.

[0039] See Figure 4 The support corner piece 51 is Z-shaped. The Z-shaped design gives the support corner piece 51 higher structural strength and enhances the support effect on the scraper 55, so that the scraper 55 can remain stable when it is impacted by materials. The guide post 52 is connected to the support corner piece 51 by a thread. The guide post 52 is fixed by the thread, which not only makes it easy to adjust the position and height of the guide post 52, but also helps the scraper 55 to maintain accurate guidance during operation.

[0040] See Figure 4 The connector 54 is L-shaped, which facilitates the secure installation of the connector 54 on the support corner piece 51 and enhances its stability under external force. The guide post 52 is set through the connector 54. This through-through design not only simplifies the movement path of the scraper 55, but also provides stable guidance for the scraper 55 when cleaning materials. One end of the guide post 52 is fixedly connected to a disc for limiting its position. The presence of the disc ensures that the guide post 52 can be fixed in the predetermined position when subjected to the action of the spring 53, preventing the guide post 52 from loosening or shifting position.

[0041] See Figure 1 Above the other end of the support 1, there is a feeding rack 4, which provides a stable input position for the material to be conveyed. The feeding rack 4 includes two parallel crossbeams 41. The structural design of the crossbeams 41 enables them to carry a large amount of ore or material to be processed and guide the material into the conveying channel of the conveyor belt. Inclined plates 42 are arranged opposite each other on the inner side of the two crossbeams 41. The inclined plates 42 are inclined to form a material guiding channel, so that the material can slide smoothly onto the conveyor belt and be conveyed in time. The inclined design of the inclined plates 42 further reduces the risk of material accumulation and jamming.

[0042] The working principle of this utility model is as follows:

[0043] When in use, the material to be conveyed is put between the two inclined plates 42, and the material will slide down through the inclined plates 42 onto the conveyor belt set on the support 1.

[0044] Driven by the drive motor 3, the drive roller 2 rotates synchronously, and the drive roller 2 drives the transmission belt to rotate synchronously. As the conveyor belt rotates, the material on it is conveyed.

[0045] During the conveying process, the material remaining on the surface of the conveyor belt will be scraped off by the scraper 55;

[0046] The specific scraping process is as follows:

[0047] When the conveyor belt with residual material passes the location of the scraper assembly 5, the material will come into contact with the scraper 55. When the material touches the scraper 55, it will be scraped off by the scraper 55. If the material is tightly adhered to the conveyor belt, the material will put pressure on the scraper 55. When the scraper 55 is squeezed by external force, it will move along the axial direction of the guide post 52 to separate the scraper 55 from the material. This can prevent the scraper 55 from being damaged by external force.

[0048] When the material that has not been scraped off passes over the scraper 55, the scraper 55 can be reset by the action of the spring 53.

[0049] Material that is not scraped off will be scraped off again by scraper 55 when it passes through scraper 55 again. This repeated scraping method can reduce the damage to scraper 55 and conveyor belt.

[0050] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
