Description

Technical Field

[0001] This utility model relates to the field of open-pit coal mining technology, and in particular to a coal cleaning device for a mining machine and a mining machine. Background Technology

[0002] An open-pit mine is a continuous open-pit mining machine that uses cutting teeth mounted around the drum to break up and collect the sludge or mineral products, which are then loaded onto a conveyor belt on the machine. When mining coal with a twin-drum open-pit mine, coal falling from the sides or drums often causes the front of the tracked walking device to be raised, increasing the overall height of the machine and affecting the mining height.

[0003] Therefore, how to improve the phenomenon that the front end of the tracked walking device is raised due to the coal falling from the side or the coal falling from the drum is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0004] The purpose of this utility model is to provide a coal cleaning device and a mining machine that can effectively improve the phenomenon that the front end of the tracked walking device is raised due to coal falling from the side or rolling coal.

[0005] To achieve the above objectives, this utility model provides a coal cleaning device for a mining machine, comprising:

[0006] A mounting base for connecting to and fixing relative to a mining machine, the mounting base being located on at least one side of the tracked traveling device of the mining machine in a first direction and spaced apart from the tracked traveling device;

[0007] The coal cleaning plate is connected to the bottom of the fixed base. The coal cleaning plate includes a working surface located on the side of the coal cleaning plate away from the track walking device. The working surface is used to contact the floating coal when the mining machine is traveling and push the floating coal out of the track walking device on one side in the first direction.

[0008] In one possible implementation, a lifting assembly is also included, comprising:

[0009] The cylinder block is connected to the fixed base;

[0010] The piston rod is movably connected at one end to the cylinder body and at the other end to the top of the coal cleaning plate. The piston rod can move axially relative to the cylinder body to drive the coal cleaning plate to move closer to and further away from the fixed seat in the axial direction of the piston rod.

[0011] In one possible implementation, a guiding component is also included, the guiding component comprising:

[0012] A guide groove is formed at the bottom of the mounting base;

[0013] The guide member has one end connected to the top of the coal cleaning plate and the other end movably connected to the guide groove, and the extension direction of the guide member is parallel to the axial direction of the piston rod.

[0014] In one possible implementation, the working surface extends along a second direction, which is at an angle to the first direction. The projection of the working surface along the first direction is a rectangle, and the projection of the working surface along the second direction is an arc.

[0015] In one possible implementation, the working surface includes a first end and a second end, which are located at opposite ends of the working surface in a second direction. The distance between the first end and the tracked traveling device in the first direction is greater than the distance between the second end and the tracked traveling device in the first direction.

[0016] In one possible implementation, there are four fixed seats, two of which are located on both sides of one tracked walking device in the first direction, and the other two fixed seats are located on both sides of another tracked walking device in the first direction. The number of coal cleaning plates is the same as the number of fixed seats and they correspond one-to-one. In the two corresponding coal cleaning plates in the opposite directions of the two tracked walking devices, the distance between the two first ends is equal to the distance between the opposite ends of the two tracked walking devices, and the distance between the two second ends is less than the distance between the opposite ends of the two tracked walking devices.

[0017] In one possible implementation, the angle between the second direction and the first direction is 70°-80°.

[0018] In one possible implementation, the tangential direction of any point on the bottom edge of the working surface is perpendicular to the axial direction of the piston rod.

[0019] In one possible implementation, the mounting base has an extended plate that is perpendicular to a first direction. The extended plate has a mounting hole with an axis extending along the first direction. The mounting hole is for a connector to pass through to fix the extended plate to the mining machine, and the side of the extended plate away from the tracked walking device is in contact with the mining machine.

[0020] This application also provides a mining machine, including a mining machine coal cleaning device as described in any of the above claims.

[0021] Compared with the above-mentioned background technology, the coal cleaning device for mining machines provided by this utility model includes a fixed base and a coal cleaning plate. The fixed base is used to connect to and fix relative to the mining machine. The fixed base is located on at least one side of the track walking device of the mining machine in a first direction and is spaced apart from the track walking device. The coal cleaning plate is connected to the bottom of the fixed base. The coal cleaning plate includes a working surface. The working surface is located on the side of the coal cleaning plate away from the track walking device. The working surface is used to contact the floating coal when the mining machine is moving and push the floating coal out of the track walking device on one side in the first direction.

[0022] Specifically, a fixed seat is added to the mining machine, located on one side of the tracked walking device in the first direction. By connecting a coal cleaning plate, including the working face, to the bottom of the fixed seat, when the tracked walking device moves along the first direction and drives the mining machine in the first direction, the working face on the side of the coal cleaning plate away from the tracked walking device can contact the floating coal in the walking direction. The floating coal is pushed out of the tracked walking device on one side in the first direction by the working face moving synchronously with the mining machine. This setting can promptly clean the floating coal close to the tracked walking device when the mining machine moves along the first direction, effectively improving the phenomenon that the front end of the tracked walking device is raised due to coal falling from the side or the roller.

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.

[0034] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "inner" and "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0036] The purpose of this utility model is to provide a coal cleaning device and a mining machine that can effectively improve the phenomenon that the front end of the tracked walking device is raised due to coal falling from the side or rolling coal.

[0037] It should be noted that in this embodiment, the X direction in the attached figure is defined as the first direction, the Y direction is defined as the second direction, and the first direction and the second direction are set at an angle.

[0038] Please see Figures 1 to 4 To achieve the above objectives, this utility model provides a coal cleaning device for a mining machine, including a fixed base 100 and a coal cleaning plate 300. The fixed base 100 is used to connect to and be fixed relative to the mining machine 200, so that the fixed base 100 can move synchronously with the movement of the mining machine 200. The mining machine 200 can be, but is not limited to, a double-drum open-pit mining machine 200. The fixed base 100 is located on at least one side of the track walking device 210 of the mining machine 200 in the first direction and is spaced apart from the track walking device 210. That is, the fixed base 100 has no direct contact with the track walking device 210. The track walking device 210 is the power mechanism for the operation of the mining machine 200. The movement of the track walking device 210 enables the mining machine 200 to move as a whole and drives the fixed base 100 to move.

[0039] The coal cleaning plate 300 is connected to the bottom of the fixed base 100. When the fixed base 100 moves synchronously with the movement of the mining machine 200, it can drive the coal cleaning plate 300 to move. The coal cleaning plate 300 includes a working surface 310, which has a certain surface area. The working surface 310 is located on the side of the coal cleaning plate 300 away from the track walking device 210. The working surface 310 is used to contact the floating coal when the mining machine 200 moves and push the floating coal out of the track walking device 210 on one side in the first direction. The first direction is the length direction of the track walking device 210. The coal wall side is usually located on one or both sides of the track walking device 210 in the first direction. The mining of the coal wall side is realized by the reciprocating movement of the mining machine 200 in the first direction.

[0040] A fixed base 100 is added to the mining machine 200, located on one side of the tracked walking device 210 in the first direction. A coal cleaning plate 300, including the working face 310, is connected to the bottom of the fixed base 100. When the tracked walking device 210 moves along the first direction and drives the mining machine 200 to move along the first direction, the working face 310 on the side of the coal cleaning plate 300 away from the tracked walking device 210 can contact the floating coal in the walking direction. The working face 310 moves synchronously with the mining machine 200 and pushes the floating coal out of the tracked walking device 210 on one side in the first direction. With this setting, the floating coal close to the tracked walking device 210 when the mining machine 200 moves along the first direction can be cleaned in time, which can effectively improve the phenomenon that the front end of the tracked walking device 210 is raised due to coal falling from the side or the roller falling.

[0041] In one possible implementation, a lifting assembly is also included, comprising a cylinder 400 and a piston rod. The cylinder 400 is connected to the fixed base 100. One end of the piston rod is movably connected to the cylinder 400, and the other end is connected to the top of the coal cleaning plate 300. The piston rod is axially movable relative to the cylinder 400 to drive the coal cleaning plate 300 to move closer to and further away from the fixed base 100 in the axial direction of the piston rod.

[0042] The movement of the piston rod relative to the cylinder 400 enables the lifting and lowering of the coal cleaning plate 300 relative to the fixed seat 100. When the mining machine 200 is cutting coal normally, the piston rod extends relative to the cylinder 400, causing the coal cleaning plate 300 to move downward relative to the fixed seat 100, contacting the coal falling from the side or the coal falling from the drum, and cleaning the coal falling from the side or the coal falling from the drum during the movement of the mining machine 200. When the mining machine 200 is traveling without a load, the piston rod retracts relative to the cylinder 400, causing the coal cleaning plate 300 to move upward relative to the fixed seat 100, increasing the height of the coal cleaning plate 300 off the ground, effectively reducing the contact between the coal cleaning plate 300 and obstacles on the ground, so that the mining machine 200 can maintain a relatively fast operating speed when traveling without a load.

[0043] The height of the fixed seat 100 or the maximum stroke of the piston rod can be adjusted according to actual needs, so that when the piston rod extends to the maximum distance relative to the cylinder 400, the distance between the bottom of the coal cleaning plate 300 and the ground is a preset distance. This preset distance does not affect the normal coal cutting movement of the mining machine 200 and can effectively clean up coal falling from the side or the roller.

[0044] To ensure that the coal cleaning plate 300 remains stable after contacting the coal falling plate or the coal falling roller, the cylinder 400 and the piston rod can be set into multiple groups and share the same hydraulic system, so that the state of each group of cylinder 400 and piston rod is consistent, that is, the piston rod is in the same position relative to the connected cylinder 400 and extends or retracts at the same time.

[0045] In one possible implementation, a guide assembly is also included. The guide assembly includes a guide groove and a guide member. The guide groove is formed at the bottom of the fixed base 100. One end of the guide member is connected to the top of the coal cleaning plate 300, and the other end is movably connected to the guide groove. The extension direction of the guide member is parallel to the axial direction of the piston rod. The guide member can slide relative to the guide groove in a preset direction. The guide groove can restrict the movement of the coal cleaning plate 300, which has a guide member on top, except in the preset direction. This effectively ensures that when the piston rod drives the coal cleaning plate 300 to move up or down relative to the fixed base 100, it can move in the preset direction, effectively reducing the shaking of the coal cleaning plate 300 and improving the movement accuracy of the coal cleaning plate 300.

[0046] The guide component can be, but is not limited to, a block structure or a rod structure. The guide groove can be adapted to the shape of the guide component. The length of the guide component should be greater than the length of the piston rod to prevent the guide component from disengaging from the guide groove when the piston rod extends to its limit position. The guide groove can also be used to limit the extension of the guide rod to limit the limit position of the coal cleaning plate 300 in the axial direction of the piston rod, thereby limiting the limit position of the piston rod extension and retraction.

[0047] In one possible implementation, the working surface 310 extends along a second direction, which is angled to the first direction. The projection of the working surface 310 along the first direction is rectangular, and the projection of the working surface 310 along the second direction is arc-shaped. That is, the working surface 310 is an arc-shaped surface extending along the second direction, and the projection of the arc-shaped surface in the first direction is rectangular. When the working surface 310 is set to an arc shape, the contact area between the working surface 310 and the floating coal can be increased. At the same time, the arc-shaped working surface 310 can guide the movement of the floating coal on the working surface 310, making it easier for the floating coal to move out of the tracked walking device 210 on one side in the first direction along the working surface 310.

[0048] In one possible implementation, the working face 310 includes a first end 320 and a second end 330, located at opposite ends of the working face 310 in a second direction. The distance between the first end 320 and the tracked walking device 210 in the first direction is greater than the distance between the second end 330 and the tracked walking device 210 in the first direction. That is, the working face 310 is inclined relative to the first direction. The first end 320, with a larger distance between the working face 310 and the tracked walking device 210, contacts the floating coal first. Then, as the working face 310 moves along the first direction, the floating coal... Guided by the working surface 310, the device moves towards the second end 330 and moves out of the working surface 310 along the second end 330, so that at least part of the floating coal is moved out of the tracked walking device 210 on one side in the first direction along the working surface 310. This effectively reduces obstacles in the first direction of the tracked walking device 210 and improves the phenomenon that the front end of the tracked walking device 210 is raised due to contact between the tracked walking device 210 and the floating coal. The angle between the second direction and the first direction is preferably 70°-80°, that is, the angle between the extension direction of the working surface 310 and the first direction is preferably 70°-80°, which has a better effect on cleaning the floating coal.

[0049] In one possible implementation, the mining machine 200 includes two tracked walking devices 210 spaced apart, and the tracked walking devices 210 can typically reciprocate in a first direction. Four fixed seats 100 can be set, with two fixed seats 100 located on both sides of one tracked walking device 210 in the first direction, and the other two fixed seats 100 located on both sides of the other tracked walking device 210 in the first direction. The number of coal cleaning plates 300 is the same as that of the fixed seats 100 and they correspond one-to-one, so as to effectively clean the floating coal on both sides of the two tracked walking devices 210 in the first direction.

[0050] In the two coal cleaning plates 300 corresponding to the two tracked walking devices 210 facing each other, the distance between the two first ends 320 is equal to the distance between the opposite ends of the two tracked walking devices 210, that is, the first ends 320 are located on the outside and aligned with the outside of the tracked walking devices 210 in the first direction. The distance between the two second ends 330 is less than the distance between the opposite ends of the two tracked walking devices 210, that is, the second ends 330 are located on the inside and are closer to the coal cleaning plate than the inside of the tracked walking device 210. In the middle of the mining machine 200, the floating coal located in the first direction of the two tracked walking devices 210 is guided between the two tracked walking devices 210 by the movement of the mining machine 200, which facilitates subsequent centralized cleaning or transfer. In addition, the tangential direction of any point on the bottom edge of the working face 310 is perpendicular to the axis of the piston rod, so that the floating coal can enter the working face 310. The tangential direction of any point on the top edge of the working face 310 is parallel to the axis of the piston rod, so as to effectively prevent the floating coal from turning over the working face 310 in the first direction.

[0051] In one possible implementation, the mounting base 100 is provided with an extended plate 110, which is perpendicular to the first direction. The extended plate 110 is provided with mounting holes 120 whose axes extend along the first direction. There are multiple mounting holes 120, which are arranged sequentially in the vertical direction. The mounting holes 120 are used for connecting members to pass through to fix the extended plate 110 to the mining machine 200. The side of the extended plate 110 away from the track walking device 210 is in contact with the mining machine 200 to ensure the fixing effect between the mounting base 100 and the mining machine 200.

[0052] Based on the above, this application also provides a mining machine 200, including the aforementioned mining machine coal cleaning device. The mining machine 200 also possesses all the beneficial effects of the aforementioned mining machine coal cleaning device. The mining machine 200 further includes a tracked walking device 210, a rocker arm drum cutting device, and a star wheel shovel. The tracked walking device 210 is used to travel back and forth along the ore mining face. The ore mining face is usually located on one or both sides of the tracked walking device 210 in the first direction. The rocker arm drum cutting device is used to cut the ore layer. The star wheel shovel is located below the rocker arm drum cutting device and is used to collect the cut ore back and forth. The remaining structure of the mining machine 200 can refer to the prior art, and will not be described in detail here.

[0053] 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.

[0054] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
