Description

Technical Field

[0001] This application relates to the field of mining machine technology, and in particular to a multi-transporter cross-distributed mining machine. Background Technology

[0002] The drum mining machine cuts and crushes the ore layer through a rotating cutting drum. As the drum rotates and the mining machine advances, the ore is gradually crushed and automatically falls into the mining machine's built-in transportation system. After further processing, the ore is transported to the ground or a designated storage point.

[0003] Current mining machines typically use unidirectional coal collection and transportation. In actual operation, the mining machine needs to turn around and back to cut the ore layers on both sides. During the turning around and back operation, the mining machine will run back and forth with empty cutter blades, resulting in low cutting efficiency, low production capacity, and inability to meet the production capacity requirements of open-pit mines.

[0004] Therefore, there is an urgent need for a mining machine that can collect and transport coal in both directions. Utility Model Content

[0005] The purpose of this application is to provide a multi-transporter cross-distributed mining machine that solves the problem of bidirectional coal transportation in mining machines, avoids empty cutter runs, and improves mining efficiency.

[0006] To achieve the above objectives, this application provides a multi-transporter cross-distributed mining machine, comprising:

[0007] A traveling device for enabling the mining machine to travel back and forth;

[0008] The transportation unit includes a left conveyor, a right conveyor, and a transfer conveyor mounted on the traveling device. The left and right conveyors are arranged symmetrically in a figure-eight pattern. The discharge ports of the left and right conveyors are close to each other and located above the traveling device. The loading port of the transfer conveyor is located directly below the discharge ports of the left and right conveyors and is used to transfer the ore from the left and right conveyors. The transfer conveyor is rotatably mounted on the traveling device, and during rotation, the position of the loading port of the transfer conveyor is fixed while the position of the discharge port changes.

[0009] Preferably, the loading ports of the left and right conveyors are located on the left and right sides of the traveling device, respectively. The left and right sides of the traveling device are also provided with a left loading section and a right loading section, respectively, for loading the cut ore onto the left and right conveyors.

[0010] Preferably, it also includes a roller cutting device, which can be raised and lowered and installed on the left and right ends of the traveling device near the mining face of the ore, for cutting the ore in staggered layers.

[0011] Preferably, the roller cutting device includes a rocker arm that can be lifted and lowered and connected to the traveling device and a spiral roller installed at the top of the rocker arm, and the traveling device is provided with a hydraulic system for controlling the lifting and lowering of the rocker arm.

[0012] Preferably, the walking device is equipped with a drive motor and a rotating mechanism. The drive motor is used to drive the rotating mechanism to rotate. The loading end of the transfer conveyor is located on the rotating mechanism and rotates synchronously with the rotating mechanism. During the rotation of the transfer conveyor, the loading port of the transfer conveyor is always located below the unloading ports of the left conveyor and the right conveyor.

[0013] Preferably, in the width direction of the traveling device, the unloading port of the transfer conveyor protrudes from the traveling device.

[0014] Preferably, the unloading ports of the left and right conveyors are both connected in a closed manner to the loading port of the transfer conveyor to form a closed dust-free point.

[0015] Preferably, the walking device is a tracked walking device.

[0016] Preferably, the left conveyor, the right conveyor, and the transfer conveyor are all end-discharge conveyors, and the discharge port of each conveyor is located diagonally above its loading port.

[0017] Preferably, the left conveyor, the right conveyor, and the transfer conveyor are scraper conveyors or belt conveyors.

[0018] Compared to the aforementioned background technology, this application, through the cross arrangement of the left conveyor, right conveyor, and transfer conveyor, allows the mining machine to cut the ore layer to the left or right. Regardless of the cutting direction, the cut ore can be transferred and transported via the transfer conveyor. Furthermore, the transfer conveyor is rotatably mounted on the traveling device. During rotation, the loading port position of the transfer conveyor remains fixed, ensuring it can receive ore from both the left and right conveyors, while the unloading port position changes. This allows the unloading port to rotate to different unloading positions according to actual site conditions, meeting production needs. Therefore, the mining machine of this application solves the problem of bidirectional coal collection and transportation in double-drum open-pit mining machines, avoiding empty cutter runs and improving mining efficiency.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "upper," "lower," "front," and "rear" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, "first," "second," "third," and "fourth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] like Figure 1As shown, in this embodiment, a multi-transporter cross-distributed mining machine is provided. The mining machine includes a walking device 1, which can be used to travel back and forth along one side of the ore mining face, thereby enabling the entire mining machine to travel back and forth. A transport unit is provided on the walking device 1, which is used to transfer the cut ore to the target location.

[0028] Specifically, the transportation unit includes a left conveyor 2, a right conveyor 3, and a transfer conveyor 4 mounted on the traveling device 1. The left and right conveyors 2 and 3 are arranged symmetrically in a figure-eight pattern. The discharge ports of the left and right conveyors 2 and 3 are close to each other but spaced apart to ensure that the ore on them can fall smoothly. The discharge ports of the left and right conveyors 2 and 3 are located above the traveling device 1, while the loading port of the transfer conveyor 4 is located directly below the discharge ports of the left and right conveyors 2 and 3. This allows the ore unloaded from the left or right conveyor 2 to fall onto the transfer conveyor 4, thus enabling the transfer conveyor 4 to transport the ore.

[0029] Furthermore, the transfer conveyor 4 is rotatably mounted on the traveling device 1, meaning that the transfer conveyor 4 rotates as a whole around a vertical axis. During the rotation, the position of the loading port of the transfer conveyor 4 does not change; that is, the loading port of the transfer conveyor 4 remains directly below the unloading ports of the left conveyor 2 and the right conveyor 3, ensuring that it can receive the ore from the left conveyor 2 and the right conveyor 3. However, during the rotation of the transfer conveyor 4, the position of its unloading port will change, thus allowing the ore to be selectively transported to a designated area or designated storage point on the ground according to the current construction situation, resulting in higher operability and a wider range of applications.

[0030] For example, when the ore layer affects the transport vehicle to reach below the unloading port of the transfer conveyor 4, the position of its unloading port can be adjusted outward by rotating the transfer conveyor 4, so that the transport vehicle does not need to reach the original unloading position. That is, the unloading port of the transfer conveyor 4 can be adjusted to be above the transport vehicle by rotation, so as to achieve the purpose of adjusting the position of the unloading port of the transfer conveyor 4 according to the actual unloading position.

[0031] In summary, this application, through the cross arrangement of the left conveyor 2, right conveyor 3, and transfer conveyor 4, allows the mining machine to cut the ore layer to the left or right. Regardless of the cutting direction, the cut ore can be transferred and transported via the transfer conveyor 4. Furthermore, the transfer conveyor 4 is rotatably mounted on the traveling device 1. During rotation, the loading port position of the transfer conveyor 4 remains fixed, ensuring it can receive ore from the left conveyor 2 and right conveyor 3. However, the unloading port position changes, allowing it to rotate to different unloading positions according to actual site conditions to meet production needs. Therefore, the mining machine of this application solves the problem of bidirectional coal collection and transportation in double-drum open-pit mining machines, avoiding empty cutter runs and improving mining efficiency.

[0032] In this embodiment, the loading ports of the left conveyor 2 and the right conveyor 3 are located on the left and right sides of the traveling device 1, respectively. Correspondingly, the left loading section 5 and the right loading section 6 are provided on the left and right sides of the traveling device 1, respectively. The two loading sections can load the ore on the corresponding side and load the cut ore onto the left conveyor 2 and the right conveyor 3.

[0033] When the mining machine moves to the left to cut the ore, the right loading unit 6 and the right conveyor 3 stop working. The left loader collects the ore into the chute of the left conveyor 2, which then transfers the ore to the chute of the transfer conveyor 4, from which the coal is transported out. When the mining machine moves to the right to cut the ore, the left loading unit 5 and the left conveyor 2 stop working. The right loader collects the ore into the chute of the right conveyor 3, which then transfers the coal to the chute of the transfer conveyor 4, from which the coal is transported out, thus realizing the bidirectional transport, transfer, and unloading function.

[0034] In some embodiments, the mining machine also includes a drum cutting device; please refer to... Figure 1 and Figure 2 The drum cutting devices are vertically and flexibly mounted on the left and right sides of the traveling device 1, located outside the loading section. When the mining machine is operating, the drum cutting devices are the first to contact the ore, cutting it. Furthermore, the drum cutting devices are positioned close to the ore face; specifically, they protrude from the traveling device 1 in its width direction, allowing them to cut the ore and preventing collisions between the traveling device 1 and the ore layer. The drum cutting devices on both sides of the traveling device 1 can be used for staggered cutting of the ore, ensuring a large cutting area and guaranteeing cutting efficiency.

[0035] Furthermore, the drum cutting device includes a rocker arm 8 that is vertically connected to the traveling device 1 and a spiral drum 7 mounted on the top of the rocker arm 8. When cutting the ore layer, the spiral drum 7 is inclined inward and pressed against the ore mining surface. The spiral drum 7 itself also has a certain inclined structure. Please refer to [reference needed]. Figure 3 This allows the sidewalls of the ore layer to be tilted at a certain angle after the front and rear spiral rollers 7 cut the ore layer, thus preventing sidewall spalling and collapse. The traveling device 1 is also equipped with a hydraulic system 9 that controls the lifting and lowering of the rocker arm 8, which can adjust the height of the two spiral rollers 7 according to the actual situation to achieve precise cutting of the ore layer; the hydraulic system 9 can refer to existing technology, and will not be described in detail here.

[0036] The above describes the transfer conveyor 4 as rotatably mounted on the traveling device 1. In this embodiment, the transfer conveyor 4 can be rotated by installing a drive motor and a rotating mechanism 10 on the traveling device 1. Specifically, the rotating mechanism 10 can be a rotating flange mounted on the upper surface of the traveling device 1. The power end of the drive motor meshes with the rotating flange, thereby driving the rotating flange to rotate. The feed end of the transfer conveyor 4 can be fixed to the rotating flange, and the connection strength between the transfer conveyor 4 and the rotating flange is strengthened by a support rod, while ensuring that the rotating flange has sufficient support strength so that the transfer conveyor 4 can be stably mounted. Based on this, since the rotating flange is located at the feed end of the transfer conveyor 4, when the drive motor drives the rotating flange to rotate, the feed port of the transfer conveyor 4 is always located below the discharge ports of the left conveyor 2 and the right conveyor 3, ensuring that the ore can be transferred from the left conveyor 2 or the right conveyor 3 to the transfer conveyor 4.

[0037] Furthermore, in the width direction of the traveling device 1, the discharge port of the transfer conveyor 4 protrudes beyond the traveling device 1, meaning the discharge port of the transfer conveyor 4 is located outside the traveling device 1, ensuring that the ore can be transported to the designated ground or mine car outside the traveling device 1. The width direction of the traveling device 1 is a horizontal direction perpendicular to the traveling direction of the traveling device 1.

[0038] The unloading ports of the left conveyor 2 and the right conveyor 3 are both connected to the loading port of the transfer conveyor 4 in a closed manner, thus forming a closed dust-free point. The closed connection can be achieved by a dustproof plate, which forms a dustproof channel to achieve dust-free transfer. Furthermore, considering that the transfer conveyor 4 also needs to rotate, the closed connection can also use a dustproof cloth with high wear resistance. That is, the dustproof cloth can be used to achieve a soft connection between the unloading ports of the left conveyor 2 and the right conveyor 3 and the loading port of the transfer conveyor 4, so as to achieve a highly efficient dustproof effect without affecting the rotation of the transfer conveyor 4 relative to the left conveyor 2 and the right conveyor 3.

[0039] The walking device 1 in this embodiment includes, but is not limited to, a tracked walking device, which has the advantages of strong all-terrain adaptability, strong climbing ability, high stability and safety. Of course, a wheeled walking device can also be used, which can be selected according to the actual situation. It will not be described in detail here, but all of them fall within the protection scope of this application.

[0040] In some embodiments, the left conveyor 2, the right conveyor 3, and the transfer conveyor 4 are all end unloading machines, and the unloading port of each conveyor is located diagonally above its loading port. This ensures that there is sufficient space below the unloading ports of the left conveyor 2 and the right conveyor 3 to accommodate the transfer conveyor 4, and provides space for the transfer conveyor 4 to rotate. At the same time, it also ensures that there is sufficient space below the unloading port of the transfer conveyor 4 for the transfer of ore.

[0041] Furthermore, the left conveyor 2, the right conveyor 3, and the transfer conveyor 4 are either scraper conveyors or belt conveyors, which can be selected according to actual needs. They will not be described in detail here, but all fall within the scope of protection of this application.

[0042] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

[0043] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
