Description

Technical Field

[0001] The invention relates to the technical field of open-pit mining, in particular to an open-pit mine belt conveyor. Background Art

[0002] Open-pit mining is to remove the loose soil and surrounding rock covering the upper part of the ore body and its surroundings, transport the waste rock to the spoil dump, and directly mine ore from the exposed ore body. When the ore body is shallowly buried or there is an outcrop on the surface, open-pit mining is superior to underground mining. The work of stripping the upper rock and soil is called stripping. The ratio of the amount of stripped rock and soil to the amount of mined ore is called the stripping ratio. For open-pit mines with too large stripping ratios, the cost of open-pit mining is high, and underground mining methods should be used instead. Open-pit mining is an independent production and operation unit that mines ore with a certain mining boundary. According to the transportation method of open-pit mines, it is divided into railway transportation development, road transportation development, horizontal shaft development, slope winch (lifting) development and belt transportation development.

DETAILED DESCRIPTION

[0028] See also Figure 1-9The present invention provides a technical solution: an open-pit mine belt conveyor, comprising a mounting frame 1, a mounting frame 2 is slidably connected to the left side wall of the mounting frame 1, and a driving component for driving the mounting frame 2 to move in the vertical direction is arranged on the mounting frame 1; a first transmission roller 3 and a second transmission roller 4 are rotatably connected to the inner wall of the mounting frame 1, the second transmission roller 4 is located just to the left of the first transmission roller 3, a third transmission roller 5 is rotatably connected to the inner wall of the mounting frame 2, and a plurality of supporting rollers 6 are also fixedly connected to the inner wall of the mounting frame 1, the plurality of supporting rollers 6 are all located below the first transmission roller 3, a tensioning roller 7 is arranged between two adjacent supporting rollers 6, and a first slider is rotatably connected to the rotating shaft of the tensioning roller 7 8. The first sliders 8 are slidably connected to the mounting frame 1 in the vertical direction. The tops of the first sliders 8 are fixedly connected with pressure springs 9. The tops of the pressure springs 9 are fixedly connected with the mounting frame 1. The first transmission roller 3, the second transmission roller 4, the third transmission roller 5, the support roller 6 and the tensioning roller 7 are jointly transmission-connected with a conveying belt 10. A push plate 11 is arranged above the conveying belt 10. A telescopic storage frame 12 for storing the push plate 11 is arranged on the left side of the mounting frame 2. A recovery conveying assembly is also arranged on the mounting frame 1. The recovery conveying assembly recovers the push plate 11 after the conveying belt 10 drives the push plate 11 to move to the inner side of the mounting frame 1, and conveys the push plate 11 to the telescopic storage frame 12 for storage.

[0029] When the above scheme is put into practical use, when the ore is mined, the mounting frame 1 is placed on the upper side of the mine hole, so that the mounting frame 2 is located directly above the mine hole. At this time, the conveyor belt 10 between the second transmission roller 4 and the third transmission roller 5 is in an inclined state. After the ore is mined, the staff places the ore above the inclined conveyor belt 10 between the second transmission roller 4 and the third transmission roller 5. At this time, the push plate 11 can block the ore, so that the ore will not fall from the conveyor belt 10, and the ore will not fall from the conveyor belt 10 when it is transported on the conveyor belt 10. The ore is then driven by the external motor to rotate the first transmission roller 3, so that the first transmission roller 3 drives the conveyor belt 10 to move and transport the ore; when the push plate 11 pushes the ore upward to the horizontal position at the top of the conveyor belt 10, the ore can be automatically transported by the conveyor belt 10, and the push plate 11 is no longer needed to block it. At this time, the push plate 11 will be driven by the recovery conveyor assembly to separate from the conveyor belt 10, and then it will be transported to the telescopic storage frame 12 by the recovery conveyor assembly, and automatically falls from the telescopic storage frame 12 to a position vertically fitted with the conveyor belt 10, and then the staff can The ore is transported to the push plate 11 again, so that the push plate 11 pushes the ore upward and moves out of the mine hole; the staff can set a screening device at the right end of the conveyor belt 10, and then the ore dropped from the right end of the conveyor belt 10 can directly fall into the screening device for screening; when the depth of the mine hole increases, the drive component is started to work, so that the drive component drives the mounting frame 2 to slide downward on the side wall of the mounting frame 1, so that the bottom of the mounting frame 2 contacts the bottom of the mine hole, and the mounting frame 2 drives the third transmission roller 5 to move downward together. When the third transmission roller 5 drives the conveyor belt 10 to move downward, the output The conveying belt 10 will drive the tensioning roller 7 to move upward. The tensioning roller 7 can keep the conveying belt in a taut state through the pressure spring 9, which can ensure that the conveying belt 10 can always maintain normal operation. After the installation frame 2 moves downward, the recovery conveying component can still transport the push plate 11 to a position vertically fitted with the conveying belt 10, which can ensure that the push plate 11 and the conveying belt 10 can complete the transportation of ore at any height. The method of directly driving the installation frame 2 to move downward by the driving component is relatively simple and does not require much time, which can greatly improve the efficiency of ore mining.

[0030] As a further solution of the present invention, the recycling conveying assembly includes two limit sliders 13, two insert blocks 14 and two first slides 15; the two limit sliders 13 are respectively slidably connected in the front and rear directions of the bottom of the push plate 11, and the sides of the limit sliders 13 are provided with first push blocks 16, the first push blocks 16 are T-shaped, and the two first push blocks 16 are respectively fixedly connected to the front and rear sides of the top of the conveyor belt 10, and the conveyor belt 10 can drive the push plate 11 to move to the right through the first push blocks 16, and the first push blocks 16 can limit the push plate 11 in all directions except the right side; the limit sliders The blocks 13 are fixedly connected with a second spring 17 for resetting the blocks 13, the limit slider 13 is fixedly connected with a first traction rope 18, the top of the first traction rope 18 is fixedly connected with a second slider 19, the second slider 19 is slidably connected to the push plate 11, and the sides of the second slider 19 are provided with a first wedge block 20 for driving the movement thereof, the first wedge block 20 is fixedly connected to the mounting frame 1; the two insert blocks 14 are respectively fixedly connected in the front and rear directions of the top of the push plate 11; the sides of the insert blocks 14 are provided with a wedge-shaped insert rod 21 for driving the upward movement thereof to disengage from the first push block 16, the wedge insert rod The right end of 21 is rotatably connected to the mounting frame 1, and a fixing portion is provided on the wedge-shaped insertion rod 21. The fixing portion fixes the insertion block 14 after the insertion block 14 is inserted into the wedge-shaped insertion rod 21. A driving portion is provided on the wedge-shaped insertion rod 21, and the driving portion is used to drive the wedge-shaped insertion rod 21 to drive the insertion block 14 to rotate. A first cylinder 22 is provided on the right side of the wedge-shaped insertion rod 21, and the first cylinder 22 is fixedly connected to the mounting frame 1. An L-shaped push plate 23 is fixedly connected to the output shaft of the first cylinder 22, and the L-shaped push plate 23 is used to push the push plate 11 to move to the left. An inclined slide 24 is provided on the left side of the L-shaped push plate 23. The slideway 24 is fixedly connected to the mounting frame 1; the two first slides 15 are respectively arranged on the front and rear sides of the mounting frame 1, and the bottom ends of the two first slides 15 are rotatably connected to the rotating shaft of the third transmission roller 5, and the first slides 15 are each provided with a first slide groove 25, and the rotating shaft of the second transmission roller 4 can rotate and slide in the first slide groove 25; the first slides 15 are each fixedly connected with a baffle 26, and the baffle 26 is arranged vertically to the first slide 15, and the top of the baffle 26 is rotatably connected to the bottom end of the telescopic storage frame 12, and the baffle 26 is U-shaped, and the inner side of the baffle 26 is located above the conveyor belt 10.

[0031] The fixing part includes two friction blocks 27 and a piston 28. The two friction blocks 27 are respectively arranged at the top and bottom of the wedge-shaped insertion rod 21, and the friction blocks 27 are slidably connected to the wedge-shaped insertion rod 21 in the vertical direction; the piston 28 is slidably connected to the wedge-shaped insertion rod 21, and a first push rod 29 is fixedly connected to the piston 28. An arc block 30 is arranged on the side of the first push rod 29, and the arc block 30 is slidably connected to the mounting frame 1. The arc block 30 is fixedly connected to a second push rod 31, and a first gas spring 32 for resetting the second push rod 31 is fixedly connected to the second push rod 31. The second push rod 31 is slidably connected to an L-shaped push rod 33, and the L-shaped push rod 33 is fixedly connected to a second gas spring 34 for resetting the L-shaped push rod 33. The L-shaped push rod 33 can be pushed to the left by the L-shaped push plate 23, and a second wedge block 35 for driving it to move outward and disengage from the contact with the L-shaped push plate 23 is arranged on the left side of the L-shaped push rod 33.

[0032] When the above scheme is put into actual use, when the push plate 11 is in contact with the conveyor belt 10 in an inclined state, the first push block 16 can limit the push plate 11, which can ensure that the push plate 11 does not move downward, and the first push block 16 can drive the push plate 11 to move to the right; after the push plate 11 drives the ore to move to a horizontal position, the push plate 11 moves to the right again to make the second slider 19 contact with the first wedge block 20, the inclined surface of the first wedge block 20 will drive the second slider 19 to slide inward, and the second slider 19 will drive the limiting slider 13 to slide inward together through the first traction rope 18, so that the limiting slider 13 is out of contact with the first push block 16, and at this time the first push block 16 can still drive the push plate 11 to The push plate 11 is then fixed by the wedge rod 21 and the drive unit is started to drive the wedge rod 21 and the push plate 11 to rotate counterclockwise (to prevent the push plate 11 from rotating). Figure 3As a reference, the arc block 30 will drive the first push rod 29 to push the piston 28 to move inwardly of the wedge-shaped insert rod 21 during the rotation process. The piston 28 will use air pressure to move the two friction blocks 27 outwardly. The two friction blocks 27 will fit tightly against the inner wall of the insert block 14, so that the friction blocks 27 will prevent the push plate 11 from falling off during the rotation process through the friction force. After the push plate 11 rotates counterclockwise from the vertical position to the horizontal position (the insert block 14 is located on the left side of the push plate 11), the first cylinder 22 is started to drive the L-shaped push plate 23 to move leftward. After the L-shaped push plate 23 moves leftward until its horizontal position is located below the push plate 11, the L-shaped push plate 2 The vertical edge of the L-shaped push plate 23 will move to the position in contact with the L-shaped push rod 33. The L-shaped push plate 23 moves to the left again, which will drive the L-shaped push rod 33 to move to the left together. The L-shaped push rod 33 will drive the arc block 30 to move to the left together through the second push rod 31, so that the arc block 30 slowly breaks away from the contact with the first push rod 29. Then the first push rod 29 and the piston 28 will move back to the initial position under the action of air pressure. After losing the push of air pressure, the friction block 27 is no longer tightly attached to the plug block 14. Then the push plate 11 will fall downward to the horizontal edge of the L-shaped push plate 23, and then be pushed to the left by the L-shaped push plate 23. When the push plate 11 moves to the left and contacts the inclined surface of the inclined slideway 24, the push plate 11 will follow the inclined surface of the inclined slideway 24. The push plate 11 is pushed upward by the L-shaped push plate 23, and when the push plate 11 moves to a position where it is out of contact with the inclined slide 24, the push plate 11 is in a vertical position and the insert block 14 is located above the top of the push plate 11, and then the L-shaped push plate 23 can be driven by the first cylinder 22 to move back to the initial position to the right, and then after the L-shaped push plate 23 is out of contact with the push plate 11, the push plate 11 will slide downward along the side of the telescopic storage frame 12 to a position in contact with the baffle 26, and then the push plate 11 will move downward along the top surface of the baffle 26 to a position perpendicular to and in contact with the conveyor belt 10, and then when the conveyor belt 10 drives the first push block 16 to move to the push plate 1 again 1, the first push block 16 will be directly inserted into the push plate 11, and then the first push block 16 can drive the push plate 11 to move upward. In this solution, since the first slide plate 15 is rotatably connected with the rotating shafts of the second transmission roller 4 and the third transmission roller 5, it can be ensured that the second transmission roller 4 can also be in a state of being perpendicular to the conveyor belt 10 when it moves to the first slide plate 15, and the baffle plate 26 can be kept perpendicular to the conveyor belt 10, so that when the push plate 11 falls from the telescopic storage frame 12 to the baffle plate 26, the push plate 11 always remains perpendicular to and fits with the conveyor belt 10, and the first push block 16 can drive the push plate 11 and the ore to move upward when it moves to contact with the push plate 11;The present invention can limit the push plate 11 by the setting of the first push block 16 through the limit slider 13, so as to ensure that the push plate 11 will not fall during the process of conveying the ore, and through the setting of the insert block 14, the first push block 16, the second spring 17, the first traction rope 18, the second slider 19, the first wedge block 20 and the wedge-shaped insert rod 21, the first push block 16 can drive the push plate 11 to move the ore to a horizontal position, so that the push plate 11 is out of contact with the first push block 16, so that the conveyor belt 10 can automatically move to the ore, and through the setting of the driving part, the wedge-shaped insert rod can drive the push plate 11 to move counterclockwise. The needle rotates to ensure that the push plate 11 will not drive the ore to move to the left when it rotates, and the fixed part is set so that the push plate 11 will not fall from the wedge-shaped rod 21 when it rotates, which can prevent the push plate 11 from hitting the ore and causing the ore to splash; the first slide plate 15 is set so that when the push plate 11 falls from the telescopic material storage frame 12 and the baffle 26 to fit on the conveyor belt 10, the push plate 11 and the conveyor belt 10 are always in a vertical state, so that the first push block 16 can drive the push plate 11 and the ore to move upward when it moves to contact with the push plate 11, which can make the ore conveying efficiency higher. ;

[0033] As a further solution of the present invention, the driving part includes a gear 36, which is fixedly connected to the rotating shaft of the wedge-shaped insertion rod 21, and the gear 36 is meshed with a rack rod 37, and the rack rod 37 is slidably connected to the mounting frame 1. A second cylinder 38 is fixedly connected to the rack rod 37, and the second cylinder 38 is fixedly connected to the mounting frame 1.

[0034] When the driving unit is working, the second cylinder 38 is started to drive the rack rod 37 to move upward, the rack rod 37 drives the gear 36 to rotate, and the gear 36 drives the wedge-shaped insert rod 21 and the push plate 11 to rotate.

[0035] As a further solution of the present invention, a first rotating shaft 39 and a second rotating shaft 40 are fixedly connected to the wedge-shaped insertion rod 21, the first rotating shaft 39 is fixedly connected to the gear 36, and a second sliding groove 41 is provided on the front and rear sides of the mounting frame 1, the second sliding groove 41 includes a vertical groove 411 and an arc groove 412, the arc groove 412 is connected to the bottom end and the vertical groove 411, the first rotating shaft 39 is slidably connected to the vertical groove 411, the second rotating shaft 40 is slidably connected to the vertical groove 411 and the arc groove 412, and the second rotating shaft can rotate in the arc groove 412.

[0036] When the above scheme is put into practical use, when the second cylinder 38 drives the rack rod 37 to move upward, the rack rod 37 will drive the first rotating shaft 39 and the second rotating shaft 40 to move upward in the vertical groove 411 through the gear 36. When the first rotating shaft 39 moves upward to the top of the vertical groove 411, the first rotating shaft 39 can no longer move upward. At this time, the gear 36 will drive the first rotating shaft 39 to rotate; the first rotating shaft 39 will drive the second rotating shaft 40 to rotate in the arc groove 412 with it as the center of the circle; through the setting of the second slide groove 41, the present invention can make the push plate 11 rotate after moving upward for a distance, so that the push plate 11 will not scrape the ore.

[0037] As a further solution of the present invention, the wedge-shaped rod 21 is L-shaped, the first rotating shaft 39 and the second rotating shaft 40 are arranged on the vertical sides of the wedge-shaped rod 21, and the first rotating shaft 39 is arranged above the second rotating shaft 40; when working, by setting the wedge-shaped rod 21 to an L-shape, the push plate 11 can move upward higher, which can better prevent the push plate 11 from scraping the ore.

[0038] As a further solution of the present invention, the driving assembly includes a threaded rod 42 and a sliding rod 43, the bottom end of the threaded rod 42 is rotatably connected to the mounting frame 1, and the top end of the threaded rod 42 is threadedly connected to the top of the mounting frame 2; the bottom end of the sliding rod 43 is fixedly connected to the mounting frame 1, and the sliding rod 43 is slidably connected to the mounting frame 2; when working, the threaded rod 42 is driven to rotate by an external motor, so that the threaded rod can drive the mounting frame 2 to move in the vertical direction.

[0039] As a further solution of the present invention, the rotating shaft of the first transmission roller 3 slides with the mounting frame 1, and a fixed block 44 is rotatably connected to the rotating shaft of the first transmission roller 3, and a third cylinder 45 is fixedly connected to the fixed block 44, and the third cylinder 45 is fixedly connected to the mounting frame 1; when working, the fixed block 44 is driven to move in the left and right directions by the third cylinder 45, so that the fixed block 44 can drive the first transmission roller 3 to move to the right, so that the conveyor belt 10 can better transport the ore to the screening device.

[0040] Working principle: When the ore is mined, the mounting frame 1 is placed on the upper side of the mine hole, so that the mounting frame 2 is located directly above the mine hole. At this time, the conveyor belt 10 between the second transmission roller 4 and the third transmission roller 5 is in an inclined state. After the ore is mined, the staff places the ore above the inclined conveyor belt 10 between the second transmission roller 4 and the third transmission roller 5. At this time, the push plate 11 can block the ore, so that the ore will not fall from the conveyor belt 10, and the ore will not fall from the conveyor belt 10 when it is transported on the conveyor belt 10, and then The external motor is started to drive the first transmission roller 3 to rotate, so that the first transmission roller 3 drives the conveyor belt 10 to move and convey the ore; when the push plate 11 pushes the ore upward to the horizontal position at the top of the conveyor belt 10, the ore can be automatically conveyed by the conveyor belt 10, and the push plate 11 is no longer needed to block it. At this time, the push plate 11 will be driven by the recovery conveyor component to separate from the conveyor belt 10, and then it will be transported to the telescopic storage frame 12 by the recovery conveyor component, and it will automatically fall from the telescopic storage frame 12 to a position vertically aligned with the conveyor belt 10, and then the staff can collect the ore again The ore is then transported to the push plate 11 for the first time, so that the push plate 11 pushes the ore upward and moves out of the mine hole; the staff can set a screening device at the right end of the conveyor belt 10, and then the ore dropped from the right end of the conveyor belt 10 can directly fall into the screening device for screening; when the depth of the mine hole increases, the driving component is started to work, so that the driving component drives the mounting frame 2 to slide downward on the side wall of the mounting frame 1, so that the bottom of the mounting frame 2 contacts the bottom of the mine hole, and the mounting frame 2 drives the third transmission roller 5 to move downward together. When the third transmission roller 5 drives the conveyor belt 10 to move downward, the conveyor belt The belt 10 will drive the tensioning roller 7 to move upward. The tensioning roller 7 can keep the conveyor belt in a taut state through the pressure spring 9, which can ensure that the conveyor belt 10 can always maintain normal operation. After the installation frame 2 moves downward, the recovery conveying component can still convey the push plate 11 to a position vertically fitted with the conveyor belt 10, which can ensure that the push plate 11 and the conveyor belt 10 can complete the transportation of ore at any height. The method of directly driving the installation frame 2 to move downward by the driving component is relatively simple and does not require much time, which can greatly improve the efficiency of ore mining.
