Abstract
Description
Technical Field
[0001] This utility model relates to the field of conveyor belt technology, specifically a mine-use stretchable rubber belt conveyor device. Background Technology
[0002] Conveyor belts are widely used mechanical equipment accessories for material transportation, characterized by their simple structure, high transport capacity, and high efficiency. They are typically made of high-strength synthetic fibers or metal wires as the skeleton material, covered with wear-resistant and corrosion-resistant synthetic rubber or plastics. Conveyor belts can operate stably in various complex environments, such as high temperature, low temperature, humidity, and dust, making them suitable for mines, ports, factories, farms, and many other applications. Driven by a drive unit, the conveyor belt allows materials to be continuously and smoothly transported from one location to another, greatly improving production efficiency and reducing labor costs.
[0003] In mining operations, conveyor belts are commonly used to transport ore. However, due to the often confined spaces within mines, existing conveyor belt systems are not well-suited to these unique spatial characteristics, and therefore cannot flexibly adjust their length to meet different conveying needs. This limitation leads to numerous inconveniences in practical use. Utility Model Content
[0004] The purpose of this invention is to provide a retractable conveyor belt device for mining, so as to solve the problem that the length of the conveyor belt cannot be adjusted in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a mine-use extendable conveyor belt device, comprising a conveyor belt support, drive rollers rotatably mounted at both ends of the conveyor belt support, a belt body disposed between the drive rollers, a support roller disposed below the belt body, an adjustment mechanism installed in the middle of the conveyor belt support, the adjustment mechanism comprising a frame fixedly mounted in the middle of the conveyor belt support, a first adjustment roller and a second adjustment roller movably mounted within the frame, and the belt body passing sequentially through the first adjustment roller and the second adjustment roller, hydraulic cylinders fixedly mounted on both sides of the frame, and a telescopic mechanism disposed at one end of the conveyor belt support.
[0006] Preferably, the conveyor belt support is provided with a movable groove, a movable slider is slidably installed in the movable groove, and the movable slider is fixedly installed at the output end of the hydraulic cylinder, and the hydraulic cylinder is provided with a retainer.
[0007] Preferably, the movable slider is provided with a bearing, and both the first adjusting roller and the second adjusting roller are rotatably mounted on the movable slider via the bearing.
[0008] Preferably, the movable slider is slidably mounted on the mechanism frame via a movable slide groove, the first adjusting roller and the second adjusting roller are both slidably mounted in the mechanism frame via the movable slider, and the hydraulic cylinder is fixedly mounted on both sides of the mechanism frame via a retainer.
[0009] Preferably, the telescopic mechanism includes a positioning sleeve fixedly installed at one end of the conveyor belt bracket, a telescopic rod slidably installed inside the positioning sleeve, a docking plate fixedly installed at the end of the telescopic rod, a drive rack fixedly installed on the telescopic rod, a drive gear rotatably installed above the drive rack, a drive shaft fixedly installed on the drive gear, a worm gear fixedly installed at one end of the drive shaft, a worm rotatably installed above the worm gear, and a drive motor connected to the worm.
[0010] Preferably, the conveyor belt support is provided with a bearing, and the drive shaft is rotatably mounted on the conveyor belt support via the bearing.
[0011] Preferably, the worm is rotatably mounted above the worm wheel via a drive motor, and the worm wheel meshes with the worm. The drive gear is rotatably mounted above the drive rack via a drive shaft, and the drive gear meshes with the drive rack.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. In this application, the forward and backward displacement of the movable slider is achieved through the extension and retraction of a hydraulic cylinder. During the forward and backward movement of the movable slider, the first and second adjusting rollers are driven to move forward and backward synchronously. When the hydraulic cylinder extends, the first and second adjusting rollers separate from each other, causing the conveyor belt body to tighten; when the hydraulic cylinder retracts, the two adjusting rollers move closer to each other, and the conveyor belt body relaxes accordingly. This mechanism allows for precise adjustment of the tension of the conveyor belt body.
[0014] 2. In this application, the drive motor is activated, which drives the worm gear to rotate. The rotation of the worm gear then drives the worm wheel, which in turn drives the drive shaft. The rotation of the drive shaft causes the drive gear to rotate, which in turn causes the drive rack to perform a telescopic action, resulting in the extension of the telescopic rod. The extension of the telescopic rod will push the drive roller forward, thereby realizing the adjustment of the length of the conveyor belt. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0021] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a mine-use extendable conveyor belt device, including a conveyor belt support 1, drive rollers 2 rotatably mounted at both ends of the conveyor belt support 1, a belt body 3 between the drive rollers 2, a support roller 4 below the belt body 3, an adjustment mechanism 5 installed in the middle of the conveyor belt support 1, and a telescopic mechanism 6 at one end of the conveyor belt support 1. By cooperating with the adjustment mechanism 5 and the telescopic mechanism 6, the length of the conveyor belt can be adjusted, thereby increasing the applicability of the conveyor belt.
[0022] like Figure 2 and Figure 3 As shown, the adjustment mechanism 5 includes a mechanism frame 501 fixedly installed in the middle of the conveyor belt support 1. A first adjusting roller 503 and a second adjusting roller 507 are movably installed in the mechanism frame 501, and the belt body 3 passes through the first adjusting roller 503 and the second adjusting roller 507 in sequence. Hydraulic cylinders 506 are fixedly installed on both sides of the mechanism frame 501. A movable slide groove 502 is opened on the conveyor belt support 1. A movable slider 504 is slidably installed in the movable slide groove 502, and the movable slider 504 is fixedly installed at the output end of the hydraulic cylinder 506. A retainer 505 is provided on the hydraulic cylinder 506, and a bearing is provided on the movable slider 504. The first adjusting roller 503 and the second adjusting roller 507 are both rotatably installed on the movable slider 504 through the bearing.
[0023] Specifically, the extension and retraction of the hydraulic cylinder 506 effectively controls the forward and backward movement of the movable slider 504. During this movement, the movable slider 504 further drives the first adjusting roller 503 and the second adjusting roller 507 to also move forward and backward accordingly. Specifically, when the hydraulic cylinder 506 extends, the first adjusting roller 503 and the second adjusting roller 507 move away from each other, stretching the belt body 3 to a taut state. Conversely, when the hydraulic cylinder 506 retracts, the first adjusting roller 503 and the second adjusting roller 507 move closer together, causing the belt body 3 to be in a relatively slack state. In this way, the tension of the belt body 3 can be precisely adjusted to adapt to different working requirements.
[0024] like Figure 2 and Figure 4 As shown, the telescopic mechanism 6 includes a positioning sleeve 601 fixedly installed at one end of the conveyor belt support 1. A telescopic rod 604 is slidably installed inside the positioning sleeve 601. A docking plate 605 is fixedly installed at the end of the telescopic rod 604. A drive rack 602 is fixedly installed on the telescopic rod 604. A drive gear 603 is rotatably installed above the drive rack 602. A drive shaft 606 is fixedly installed on the drive gear 603. A worm gear 607 is fixedly installed at one end of the drive shaft 606. A worm 608 is rotatably installed above the worm gear 607. A drive motor 609 is connected to the worm 608. A bearing is provided on the conveyor belt support 1. The drive shaft 606 is rotatably installed on the conveyor belt support 1 through the bearing.
[0025] Specifically, when the drive motor 609 is started, it begins to rotate, driving the worm gear 608 to rotate as well. The rotational motion of the worm gear 608 is transmitted to the worm wheel 607, causing the worm wheel 607 to also begin to rotate. The rotational motion of the worm wheel 607 is further transmitted to the drive shaft 606, which, upon receiving the rotational power, drives the connected drive gear 603 to rotate. During its rotation, the drive gear 603 interacts with the drive rack 602, causing the drive rack 602 to perform a telescopic action. As the drive rack 602 telescopically extends or retracts, the telescopic rod 604 extends or retracts accordingly. When the telescopic rod 604 extends, it pushes the drive roller 2 forward. This series of mechanical actions ultimately achieves the adjustment of the conveyor belt's length.
[0026] Working principle: During use, the drive roller 2 is driven to rotate by the motor. After the drive roller 2 rotates, it will drive the belt body 3 to move, thereby realizing the conveying function. The extension and retraction of the hydraulic cylinder 506 can drive the movable slider 504 to move back and forth. When the movable slider 504 moves back and forth, it will drive the first adjusting roller 503 and the second adjusting roller 507 to move back and forth. When the hydraulic cylinder 506 extends, the first adjusting roller 503 and the second adjusting roller 507 will move away from each other, so that the belt body 3 is in a taut state. When the hydraulic cylinder 506 retracts, the first adjusting roller 503 and the second adjusting roller 507 will move closer to each other, so that the belt body 3 is in a slack state, thereby adjusting the tension of the belt body 3. When the belt body 3 is in a slack state, the drive motor 609 can be started. Starting the drive motor 609 will drive the worm 608 to rotate. After the worm 608 rotates, it will drive the worm wheel 607 to rotate. After the worm wheel 607 rotates, it will drive the drive shaft 606 to rotate. After the drive shaft 606 rotates, it will drive the drive gear 603 to rotate. When the drive gear 603 rotates, it will drive the drive rack 602 to perform a telescopic action, causing the telescopic rod 604 to extend. After the telescopic rod 604 extends, it will drive the drive roller 2 to move forward, thereby adjusting the length of the conveyor belt.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
