Description

Technical Field

[0001] This utility model belongs to the field of coal gangue conveying technology, and in particular relates to a mining belt conveyor device. Background Technology

[0002] Coal gangue belt conveyors are a highly efficient and continuous material transportation method, widely used in the coal gangue processing stages of coal mines and coal washing plants. Their core principle is to use the friction between the drive drum and the conveyor belt to propel the conveyor belt carrying the material, achieving horizontal, inclined, or vertical transport of coal gangue. The conveyor belt is typically made of wear-resistant and impact-resistant rubber or polymer materials, and the idler roller system supports the belt and reduces running resistance. This conveying method is particularly suitable for long-distance, high-volume gangue transportation, such as in underground main haulage roadways, significantly improving efficiency and reducing transfer costs.

[0003] Comparing with Chinese Patent CN220375627U, a mining belt conveyor device is disclosed, comprising two vertical plates; a conveyor belt is rotatably installed within both vertical plates, and multiple protruding plates are equidistantly arranged on the outer edge of the conveyor belt. An arc plate is slidably installed at one end of each vertical plate, and two short plates are symmetrically arranged at one end of each arc plate. A threaded rod is helically installed within each of the two short plates, driving the arc plate to slide within the vertical plate. One end of the threaded rod is helically connected to the short plate, and the other end is rotatably connected to the vertical plate. Through the conveyor belt, protruding plates, arc plates, short plates, and threaded rods, the rotation of the threaded rods and the short plates drive the arc plate to slide within the vertical plate, thereby adhering to the outer edge of the conveyor belt and scraping off dust adhering to it. The arc plate reciprocates within the vertical plate, cleaning the dust between the multiple protruding plates, replacing manual cleaning and improving cleaning efficiency.

[0004] However, the aforementioned patent cleans the dust adhering to the conveyor belt by scraping back and forth, resulting in poor cleaning continuity and a lack of tension adjustment mechanism, making it impossible to adjust the tension of the transmission belt. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a mining belt conveyor to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A mining belt conveyor includes a main assembly for continuously conveying coal gangue, and an adjusting assembly for tensioning and fixing installed in the middle of the main assembly. A cleaning assembly for rotating and sweeping away adhering coal gangue is located at the lower end of the main assembly. The main assembly includes a frame with two conveying rollers symmetrically arranged on its top. One conveying roller has a first motor at one end. A first support is located in the middle of the frame, and a limiting guide roller is located on one side of the first support. A conveyor belt is installed between the two conveying rollers and the limiting guide roller. The adjusting assembly includes a fixed support fixed to the first support. A manual hydraulic cylinder is fixedly installed in the middle of the fixed support. A movable support is installed at the telescopic end of the manual hydraulic cylinder. A tensioning roller is installed in the middle of the movable support. Guide mechanisms for limiting the direction of movement are provided at both ends of the movable support. Locking mechanisms for mechanical locking to prevent pressure leakage are provided on both sides of the manual hydraulic cylinder. The cleaning assembly includes a second support with a rotary sweeping roller installed on it. The surface of the rotary sweeping roller is covered with a brush sleeve, and a second motor is located at one end of the rotary sweeping roller.

[0007] Furthermore: the locking mechanism includes two through holes symmetrically arranged on the fixed bracket and two support screws symmetrically arranged on the movable bracket, each of the support screws is equipped with two locking nuts, and the through holes are smaller than the locking nuts; the guiding mechanism includes two limiting slide rails symmetrically installed on the inner side of the fixed bracket and two limiting sliders symmetrically installed on the outer side of the movable bracket, the limiting sliders and the limiting slide rails are slidably connected.

[0008] Furthermore, the cross-section of the limiting slider is T-shaped.

[0009] Furthermore, a guide hopper is provided below the rotary sweeping roller, and the guide hopper is fixed at an incline on the second support.

[0010] Furthermore, the second bracket is installed on the frame body between the conveying roller and the limiting guide roller.

[0011] Furthermore, a plurality of support rollers are evenly distributed on the frame body between the two conveying rollers, and the two ends of the support rollers are symmetrically provided with limiting edges.

[0012] Furthermore, both the first motor and the second motor are servo motors.

[0013] Compared with existing technologies, the beneficial effects are: A servo motor-driven rotary sweeping roller, covered with a brush sleeve, is installed at the end of the conveyor belt. This continuously and efficiently removes residual coal and gangue adhering to the belt surface, preventing them from being carried into the tension roller or rotating parts and causing wear, jamming, or damage. A mechanical locking mechanism (support screw and locking nut) is installed. After adjustment, the relative positions of the movable and fixed supports are mechanically locked by tightening the nut, preventing cylinder depressurization from causing tension failure and ensuring stable tension during long-term operation. The mechanical locking mechanism is simple and reliable, requiring no continuous hydraulic pressure, reducing energy consumption and leakage risks, and extending service life. Tension adjustment is achieved by manually pushing the tension roller with a hydraulic cylinder, making operation simple. It is labor-saving; the adjustment component uses a T-shaped cross-section limit slider that slides and a limit rail to ensure that the tension roller remains parallel to the limit guide roller during adjustment, avoiding belt surface wear or uneven tension caused by skewness; both the conveying and cleaning motors are servo motors, which can adjust the speed according to the actual working conditions to adapt to different loads and cleaning needs, saving energy and providing high control precision; by integrating an anti-deviation support mechanism, a mechanical locking tension adjustment system, and an active rotation cleaning system, the reliability, maintenance convenience, and service life of the mining belt conveyor under conditions of high wear and easily adhered materials such as coal gangue are significantly improved, making it highly valuable for engineering applications.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-7 A mining belt conveyor includes a main component 1 for supporting the continuous conveying of coal gangue, and an adjustment component 2 for tensioning and fixing installed in the middle of the main component 1. A cleaning component 3 for rotating and sweeping away the coal gangue adhering to the main component 1 is provided at the lower end of the main component 1.

[0018] In this embodiment: the main component 1 includes a frame body 101, with two conveying rollers 102 symmetrically arranged on the top of the frame body 101. One of the conveying rollers 102 is equipped with a first motor 103 at one end. The first motor 103 is a servo motor. A first support 107 is arranged in the middle of the frame body 101. A limiting guide roller 105 is arranged on one side of the first support 107. A conveyor belt 104 is installed between the two conveying rollers 102 and the limiting guide roller 105. A number of support rollers 106 are evenly distributed on the frame body 101. The support rollers 106 are symmetrically provided with limiting edges 108 at both ends. During installation and adjustment, the conveyor belt 104 is sleeved between two conveying rollers 102, limiting guide rollers 105 and tension rollers 204. When conveying coal gangue, the frame body 101 supports the first motor 103 to drive the conveying rollers 102 to rotate, and push the conveyor belt 104 to move and convey coal gangue under the support of the support rollers 106. At the same time, the limiting edges 108 at both ends of the support rollers 106 prevent the conveyor belt 104 from running off-center. In this embodiment: the adjustment component 2 includes a fixed bracket 201 fixed to the first bracket 107, a manual cylinder 202 fixedly installed in the middle of the fixed bracket 201, a movable bracket 203 installed at the telescopic end of the manual cylinder 202, a tension roller 204 installed in the middle of the movable bracket 203, guide mechanisms for limiting the direction of movement provided at both ends of the movable bracket 203, and locking mechanisms for mechanical locking to prevent pressure relief provided on both sides of the manual cylinder 202; the locking mechanism includes two through holes 209 symmetrically arranged on the fixed bracket 201 and two support screws 205 symmetrically arranged on the movable bracket 203, each support screw 205 is equipped with two locking nuts 206, and the through holes 209 are smaller than the locking nuts 206; the guide mechanism includes two limiting mechanisms symmetrically installed on the inner side of the fixed bracket 201. Two limiting sliders 208 are symmetrically installed on the outside of the slide rail 207 and the movable bracket 203. The limiting sliders 208 and the limiting slide rail 207 are slidably connected. The limiting sliders 208 have a T-shaped cross-section. During installation and adjustment, the first bracket 107 supports the manual cylinder 202 through the fixed bracket 201 to apply force, which pushes the movable bracket 203 to push the conveyor belt 104 through the tension roller 204 to be tensioned under the support of the limiting guide roller 105. The limiting sliders 208 move along the limiting slide rail 207, limiting the tension roller 204 to be parallel to the limiting guide roller 105. At the same time, the movable bracket 203 drives the support screw 205 to move through the through hole 209 on the fixed bracket 201. When the tension is adjusted to a suitable level, the manual cylinder 202 is stopped, and the locking nut 206 on each support screw 205 is tightened to lock the distance between the movable bracket 203 and the fixed bracket 201, thus completing the tension adjustment. In this embodiment: the cleaning component 3 includes a second support 301, on which a rotary sweeping roller 302 is mounted. The surface of the rotary sweeping roller 302 is covered with a brush sleeve 304. A second motor 303, which is a servo motor, is provided at one end of the rotary sweeping roller 302. A guide hopper 305 is provided below the rotary sweeping roller 302 and is inclinedly fixed on the second support 301. The second support 301 is installed on the frame body 101 between the conveyor roller 102 and the limiting guide roller 105. The second support 301 supports the second motor 303 to drive the rotary sweeping roller 302 to rotate the brush sleeve 304, cleaning the surface of the conveyor belt 104 after unloading coal gangue, preventing the coal gangue adhering to the surface of the conveyor belt 104 from entering the tension roller 204 and causing damage. The cleaned coal gangue flows together through the guide hopper 305 for convenient subsequent processing.

[0019] Working principle: During installation and adjustment, the conveyor belt 104 is placed between the two conveyor rollers 102, the limiting guide roller 105, and the tension roller 204. The first bracket 107 supports the manual cylinder 202 through the fixed bracket 201 to apply force, which pushes the movable bracket 203 to push the conveyor belt 104 through the tension roller 204 to be tensioned under the support of the limiting guide roller 105. The limiting slider 208 moves along the limiting slide rail 207 to limit the tension roller 204 to be parallel to the limiting guide roller 105. At the same time, the movable bracket 203 drives the support screw 205 to move through the through hole 209 on the fixed bracket 201. When the tension is adjusted to a suitable level, the manual cylinder 202 is stopped, and the locking nut 206 on each support screw 205 is tightened to lock the distance between the movable bracket 203 and the fixed bracket 201, thus completing the tension adjustment. When conveying coal gangue, the frame 101 supports the first motor 103 to drive the conveyor roller 102 to rotate, pushing the conveyor belt 104 to move and convey the coal gangue under the support of the support roller 106. At the same time, the limiting edges 108 at both ends of the support roller 106 prevent the conveyor belt 104 from running off-center. The second bracket 301 supports the second motor 303 to drive the rotary sweeping roller 302 to drive the brush sleeve 304 to rotate, cleaning the surface of the conveyor belt 104 after unloading the coal gangue, preventing the coal gangue adhering to the surface of the conveyor belt 104 from entering the tension roller 204 and causing damage. The cleaned coal gangue flows together through the guide hopper 305 to facilitate subsequent processing.
