Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, and in particular to a multi-drum continuous mining equipment suitable for large mines. Background Art

[0002] Globally, with the growing demand for mineral resources, mining technology is also developing rapidly. Traditional mining technology and equipment, such as blasting, electric shovels, bucket wheel excavators, etc., although they perform well in some scenarios, also face many challenges, such as low operating efficiency, great safety hazards, and serious environmental impacts. In recent years, with the continuous expansion of mining scale and the increase in operation complexity, the demand for more efficient and safer mining equipment has become increasingly urgent. Especially in large-section mining operations, traditional equipment can hardly meet the requirements of high efficiency and low risk. Therefore, how to develop a mining equipment that can not only efficiently handle large-section mining faces, but also reduce environmental and safety risks has become an important research direction in the current mining field.

[0003] At present, large-scale mining excavation equipment is mainly composed of bucket wheel excavators, electric shovels, blasting drills and hydraulic hammers. The current situation is as follows:

[0004] 1. Poor applicability: For example, the current bucket wheel excavators and electric shovels are large in size and have high requirements for the working site, making them difficult to use in mining areas with complex terrain or limited space. However, blasting drills and hydraulic hammers are suitable for specific ore types or geological conditions.

[0005] 2. High risk: Equipment such as blasting drills rely on blasting operations, which poses high safety risks, such as hazards caused by vibration, flying rocks and improper explosions.

[0006] 3. Low efficiency: Hydraulic hammers are less efficient and have a slow crushing speed when dealing with large sections. Although blasting drills have high productivity, they are also poor in overall efficiency due to the intermittent nature of blasting operations. Summary of the invention

[0042] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0043] Example 1: Please refer to Figure 1-16 The present invention provides a multi-drum continuous mining equipment suitable for large mines, including a frame base plate 1, a lower cutting device 3 and an upper cutting device 6. The frame base plate 1 is symmetrically fixed with a crawler side chassis 11 on the left and right sides. The outer side of the crawler side chassis 11 is fixedly connected with a crawler walking device 12 (the crawler walking device 12 is used to control the walking and turning of the whole machine, which is a common walking device in the prior art and can provide stable movement performance). The upper end of the crawler side chassis 11 is fixedly connected with a side support plate 13. The side support plate 13 The upper end of the frame is fixedly connected to the frame top plate 2, and two groups of left and right material discharge troughs 21 are opened on the upper surface of the frame top plate 2. A driving cabin 22 is fixedly installed at the rear right side of the upper surface of the frame top plate 2, and a power box 23 is fixedly installed at the rear left side of the upper surface of the frame top plate 2. The lower cutting device 3 is slidably connected to the frame base plate 1, and two groups of lower scraper conveyors 4 are slidably connected to the frame base plate 1, and the two groups of lower scraper conveyors 4 are respectively located on the left and right sides of the lower cutting device 3. The front ends of the two groups of lower scraper conveyors 4 are connected to the lower loading device The lower loading device 5 is located below the lower cutting device 3, the upper cutting device 6 is slidably connected to the frame top plate 2, and the upper cutting device 6 is located directly above the lower cutting device 3. Two sets of upper scraper conveyors 7 are slidably connected to the frame top plate 2, and the two sets of upper scraper conveyors 7 are respectively located on the left and right sides of the upper cutting device 6, and the rear ends of the upper scraper conveyors 7 are located directly above the lower material chute 21. The front ends of the two sets of upper scraper conveyors 7 are connected to the upper loading device 8, and the upper loading device 8 is located directly below the upper cutting device 6. It is located directly above the lower cutting device 3, and the upper cutting device 6, the upper loading device 8 and the lower cutting device 3 are distributed longitudinally. A guide device 9 is fixedly connected in the lower material chute 21, and two groups of main scraper conveyors 20 are fixedly connected to the rear of the upper surface of the frame base plate 1. The main scraper conveyor 20 is fixed to the frame top plate 2 by connecting the suspension 201. The rear end of the lower scraper conveyor 4 is located directly above the front end of the main scraper conveyor 20 and the two are partially overlapped. The lower end opening of the guide device 9 is located directly above the main scraper conveyor 20.

[0044] The present invention can effectively adapt to large-section mining faces by providing a lower cutting device 3 and an upper cutting device 6, thereby improving mining efficiency. The two sets of cutting drums are respectively equipped with independent rock-breaking mechanisms such as driving, feeding, and swinging, so that they can be operated independently, thereby achieving a more flexible operation mode. The mining method of synchronous rock breaking in the upper and lower areas can carry out rock breaking operations in multiple areas at the same time, greatly improving the efficiency of ore crushing, and is particularly suitable for handling large-area ore body crushing tasks. At the same time, the lower loading device 5 and the upper loading device 8 transport the mineral materials in the upper and lower areas efficiently and quickly, respectively, through the method of zoned material transportation, thereby further improving the processing efficiency of the mineral materials. In addition, the equipment has good adaptability, can operate flexibly in a variety of terrain environments, and is widely applicable to the mining needs of various open-pit mines and underground mines.

[0045] Specifically, the lower cutting device 3 and the upper cutting device 6 operate synchronously to crush and cut the ore in the upper and lower areas respectively. In this process, the lower loading device 5 loads the ore generated in the lower area onto the lower scraper conveyor 4, and the lower scraper conveyor 4 directly transports the ore to the main scraper conveyor 20 to complete the transportation of the ore. At the same time, the upper loading device 8 loads the ore generated in the upper area onto the upper scraper conveyor 7, and the ore on the upper scraper conveyor 7 is effectively guided and transferred to the main scraper conveyor 20 through the guide device 9 to continue the subsequent transportation.

[0046] Specifically, the rear end of the lower scraper conveyor 4 is located directly above the front end of the main scraper conveyor 20 and the two partially overlap. The effect of this design is that when the front and rear positions of the lower scraper conveyor 4 change, the front end of the main scraper conveyor 20 is always below the lower scraper conveyor 4, and the ore on the upper end of the lower scraper conveyor 4 can fall onto the main scraper conveyor 20, thereby ensuring the continuous and smooth transportation of the ore.

[0047] The present invention has the following advantages:

[0048] 1. High applicability. The equipment can adapt to a variety of ore types, including hard rock and medium-hard rock, and is not limited by the shape of the ore body and geological conditions. In open-pit mines and large-section mining operations, it can better adapt to complex geological conditions and large-area mining tasks. Through the mechanical action of the upper cutting drum 65 and the lower cutting drum 35, the equipment can crush a large area of ​​ore in a short time, reducing dependence on blasting operations and reducing safety hazards and environmental impacts during operations.

[0049] 2. High safety. The equipment mechanically crushes rocks to avoid potential safety hazards such as vibration, flying rocks, and noise during blasting operations, greatly improving the safety of operations. Mechanized operation can effectively reduce the time workers are exposed to dangerous environments during mining.

[0050] 3. High efficiency. The cooperation between the two sets of cutting drums makes the rock breaking process more efficient. It can process a large area of ​​ore in a short time, which is particularly suitable for large-scale open-pit mining. And the equipment can operate continuously for a long time, which is suitable for large-scale and long-term mining tasks, and can continuously and efficiently crush rocks. Compared with the traditional single-drum rock breaker, it has the advantages of higher crushing efficiency and wider application range.

[0051] Furthermore, the lower cutting device 3 includes a lower cutting sliding seat 31, a lower cutting drum swing arm 32, a lower cutting drum swing cylinder 33, a lower cutting drum driving seat 34 and a lower cutting drum 35. The upper surface of the frame base plate 1 is fixedly connected with a U-shaped sliding seat 14. The lower cutting sliding seat 31 is slidably connected to the inner side of the U-shaped sliding seat 14. The lower cutting drum swing arm 32 is rotatably connected to the lower cutting sliding seat 31 through a pin shaft. One end of the lower cutting drum swing cylinder 33 is rotatably connected to the front side of the lower cutting sliding seat 31 through a pin shaft. The other end of the lower cutting drum swing cylinder 33 is rotatably connected to the lower surface of the lower cutting drum swing arm 32 through a pin shaft. The lower cutting drum swing cylinder 33 realizes the up and down swing of the lower cutting drum swing arm 32 by extending and shortening. The lower cutting drum 35 is connected to the lower cutting drum swing arm 32 through the lower cutting drum driving seat 34, the rear side of the U-shaped slide 14 is fixedly connected with a right-angle seat 15, the inner side of the right-angle seat 15 is fixedly connected with a lower cutting translation cylinder 16, the telescopic end of the lower cutting translation cylinder 16 is fixed to the rear side of the lower cutting sliding seat 31, and the lower cutting translation cylinder 16 realizes the front and rear translation of the lower cutting drum 35 by extending and shortening, the inner sides of the U-shaped slide 14 are fixedly connected with slide rails 141, the inner sides of the lower cutting sliding seat 31 are fixedly connected with fixed frames 311, the fixed frame 311 is rotatably connected to a side away from the lower cutting sliding seat 31 with multiple groups of rollers 312, and the rollers 312 are slidably connected to the inside of the slide rails 141.

[0052] Specifically, the lower cutting drum swing cylinder 33 is extended, and the lower cutting drum swing arm 32 is lifted, thereby completing the knife raising operation. The lower cutting drum swing cylinder 33 is gradually shortened, thereby driving the lower cutting drum swing arm 32 and the lower cutting drum 35 to move downward, thereby completing the lower cutting operation. The lower cutting translation cylinder 16 is extended, pushing the lower cutting slide seat 31 to slide forward in the U-shaped slide seat 14, thereby completing the knife feeding operation. The lower cutting translation cylinder 16 is shortened, driving the lower cutting slide seat 31 to move backward, thereby completing the bottom pulling or knife retracting operation. During the knife feeding and bottom pulling operations, the lower cutting slide seat 31 drives multiple groups of rollers 312 to slide inside the slide rail 141 through the fixed frame 311, so that the lower cutting slide seat 31 slides more steadily and smoothly.

[0053] Furthermore, a U-shaped slide 17 is symmetrically fixed on the upper surface of the frame base plate 1 and located on both sides of the U-shaped slide 14. Both sides of the interior of the U-shaped slide 17 are fixedly connected with slide rails 171. Both sides of the lower scraper conveyor 4 are fixedly connected with fixed frames 41. The side of the fixed frame 41 away from the lower scraper conveyor 4 is rotatably connected with multiple groups of rollers 42. The rollers 42 are slidably connected to the inside of the slide rails 171. A through groove 172 is penetrated through the side of the U-shaped slide 17 away from the U-shaped slide 14. A support seat 43 is fixedly connected to the inner side of the fixed frame 41 near the through groove 172. The support seat 43 is slidably connected to the inner side of the through groove 172. The outer side of the through groove 172 is fixedly connected with a lower scraper translation cylinder 18. The lower scraper translation cylinder 18 is fixedly connected to the support seat 43, and the telescopic end of the lower scraper translation cylinder 18 is fixedly connected to the support seat 43.

[0054] Specifically, when the lower scraper translation cylinder 18 is extended, its telescopic end drives the lower scraper conveyor 4 and the lower loading device 5 forward through the support seat 43 and the second fixed frame 41. When the lower scraper translation cylinder 18 is shortened, its telescopic end indirectly drives the lower scraper conveyor 4 and the lower loading device 5 backward. Thus, the lower scraper conveyor 4 and the lower loading device 5 can adjust their positions according to needs to meet different loading requirements. When the lower scraper conveyor 4 moves forward and backward, it will drive multiple groups of rollers 42 to slide in the second slide rail 171 through the second fixed frame 41 on both sides, which will make the lower scraper conveyor 4 move more smoothly.

[0055] Furthermore, the lower loading device 5 includes a lower shovel plate 51, and the rear end of the surface of the lower shovel plate 51 is penetrated by two groups of lower discharge ports 511 distributed on the left and right. The front ends of the two groups of lower scraper conveyors 4 are respectively located on the inner side of the lower discharge ports 511 on the corresponding side. The front end of the lower scraper conveyor 4 is rotatably connected to the lower surface of the lower shovel plate 51 located in front of the lower discharge port 511 through a pin shaft. The upper surface of the lower shovel plate 51 is rotatably connected to four groups of lower star wheels 52, and the four groups of lower star wheels 52 are symmetrically distributed on the left and right sides of the lower discharge port 511. The lower star wheels 52 are driven by a motor, and the motor is fixedly connected to the lower surface of the lower shovel plate 51. The rear end of the lower shovel plate 51 and one side of the lower discharge port 511 is fixedly connected with a back plate 53. The side of the back plate 53 away from the lower discharge port 511 is rotatably connected to the movable scraper 54, and the rear end corner of the lower shovel plate 51 is rotatably connected to the shovel plate side cylinder 55 through a pin shaft. The telescopic end of the shovel plate side cylinder 55 is rotatably connected to the back side of the movable scraper plate 54 through a pin shaft, and the shovel plate side cylinder 55 realizes the left and right swing of the movable scraper plate 54 by extending and shortening. The rear side of the lower shovel plate 51 is rotatably connected to four groups of shovel plate lifting cylinders 56 through pin shafts. The four groups of shovel plate lifting cylinders 56 are respectively located on the left and right sides of the two groups of lower scraper conveyors 4, and the other end of the shovel plate lifting cylinder 56 is rotatably connected to one side of the lower scraper conveyor 4 through a pin shaft. The shovel plate lifting cylinder 56 realizes the angle adjustment of the lower shovel plate 51 by extending and shortening.

[0056] Specifically, during the working process, the lower star wheels 52 on both sides of the lower discharge port 511 rotate continuously (the rotation directions of the two sets of lower star wheels 52 are opposite, the lower star wheels 52 on the left side of the lower discharge port 511 rotate clockwise, and the lower star wheels 52 on the right side of the lower discharge port 511 rotate counterclockwise), so as to move the mineral material from the lower shovel plate 51 to the lower discharge port 511, and then transport it to the lower scraper conveyor 4. By adjusting the extension and contraction of the shovel plate side oil cylinder 55, the left and right swing of the movable scraper 54 can be controlled, and then the width of the lower shovel plate 51 and the accommodating capacity of the mineral material can be adjusted. When the mineral material is accumulated to a certain extent on both sides of the lower shovel plate 51, the movable scraper 54 can scrape the accumulated mineral material to the lower star wheel 52, and then the lower star wheel 52 moves it to the lower scraper conveyor 4, so as to improve the processing efficiency and loading speed of the mineral material. Before cutting, the equipment needs to be stabilized by controlling the extension of the shovel plate lifting cylinder 56. At this time, the front side of the lower shovel plate 51 drops. When the pressure between the lower shovel plate 51 and the ground reaches the required value, the rear stabilizer is dropped (the rear stabilizer is installed at the rear of the frame base plate 1. It is a prior art and will not be described in detail in this article) to make its pressure reach the set value. With the cooperation of the lower shovel plate 51 and the rear stabilizer, the entire equipment will not tilt or become unstable during the cutting process.

[0057] Furthermore, the upper cutting device 6 includes an upper cutting sliding seat 61, an upper cutting drum swing arm 62, an upper cutting drum swing cylinder 63, an upper cutting drum drive seat 64 and an upper cutting drum 65. The upper surface of the frame top plate 2 is fixedly connected with a U-shaped slide seat 3 24. The upper cutting sliding seat 61 is slidably connected to the inner side of the U-shaped slide seat 3 24. The upper cutting drum swing arm 62 is rotatably connected to the upper cutting sliding seat 61 through a pin shaft. One end of the upper cutting drum swing cylinder 63 is rotatably connected to the front side of the upper cutting sliding seat 61 through a pin shaft. The other end of the upper cutting drum swing cylinder 63 is rotatably connected to the lower surface of the upper cutting drum swing arm 62 through a pin shaft. The upper cutting drum swing cylinder 63 realizes the up and down swing of the upper cutting drum swing arm 62 by extending and shortening. The upper cutting drum 65 is connected to the upper cutting drum swing arm 62 through the upper cutting drum drive seat 64. The upper cutting sliding seat 61 realizes forward and backward sliding through the upper cutting translation cylinder 66.

[0058] Specifically, the upper cutting drum swing cylinder 63 is extended, and the upper cutting drum swing arm 62 is lifted, thereby completing the knife raising operation. The upper cutting drum swing cylinder 63 is gradually shortened, thereby driving the upper cutting drum swing arm 62 and the upper cutting drum 65 to move downward, thereby completing the downward cutting operation. The upper cutting translation cylinder 66 is extended, pushing the upper cutting slide seat 61 to slide forward in the U-shaped slide seat 3 24, thereby completing the knife feeding operation. The upper cutting translation cylinder 66 is shortened, driving the upper cutting slide seat 61 to move backward, thereby completing the knife retracting operation.

[0059] Furthermore, the rear end of the upper scraper conveyor 7 is rotatably connected between the two groups of horizontal ear plate seats 71 through a pin shaft, the front sides of the two groups of horizontal ear plate seats 71 are fixedly connected to the longitudinal ear plate seats 72, and the lower ends of the two groups of longitudinal ear plate seats 72 are fixedly connected to movable plates 73, and the movable plates 73 are slidably connected to the upper surface of the frame top plate 2, and both sides of the movable plates 73 are fixedly connected to sliders 731. The upper surface of the frame top plate 2 and the two sides of the movable plates 73 are symmetrically fixed with guide rails 25 that match the sliders 731, and the left and right sides of the upper cutting sliding seat 61 are symmetrically fixed with fixed frames 3 611, and the fixed frames 3 611 are symmetrically fixed with the upper cutting sliding seat 61. The transverse ear plate seats 71 of the cutting sliding seat 61 are fixed to each other by connecting blocks 711, and both sides of the U-shaped sliding seat 3 24 are penetrated with through grooves 241 for sliding of the connecting blocks 711, and the upper end of the movable plate 73 and the side of the longitudinal ear plate seat 72 away from the upper scraper conveyor 7 are fixedly connected with the upper scraper swing cylinder 74, and the left and right sides of the upper scraper conveyor 7 are fixedly connected with the shaft rod 75, and the surface of the longitudinal ear plate seat 72 is penetrated with a guide groove 721, and the shaft rod 75 is slidably connected to the inside of the guide groove 721, and the upper end of the upper scraper swing cylinder 74 is rotatably connected to the lower end of the shaft rod 75 through a pin shaft.

[0060] Specifically, when the upper cutting device 6 advances, the upper cutting translation cylinder 66 extends, driving the upper cutting sliding seat 61 to move forward. At this time, the upper cutting sliding seat 61 will drive the upper scraper conveyor 7 and the upper loading device 8 to move forward synchronously through the fixed frame 3 611, the connecting block 711, and the transverse ear plate seat 71. The purpose of this is to ensure that the upper loading device 8 is always directly below the upper cutting drum 65, so that it can effectively receive the mineral material cut by the upper cutting drum 65, prevent the mineral material from falling onto the lower cutting drum 35, and prevent secondary damage to the mineral material. If the mineral material falls onto the lower cutting drum 35, it may seriously affect the normal operation and work efficiency of the lower cutting drum 35. When the two groups of cutting drums are raised at the same time, in order to avoid the generation of cutting dead angles, it is necessary to ensure that the upper loading device 8 can be lifted to an appropriate height. The upper loading device 8 is fixedly connected to the front end of the upper scraper conveyor 7, so it is only necessary to control the lifting of the upper scraper conveyor 7 to drive the upper loading device 8 to rise. The specific operation is to control the extension of the upper scraper swing cylinder 74, and its telescopic end will lift the upper scraper conveyor 7 to a certain angle through the shaft 75, thereby completing the lifting operation. When the cutting drum cuts downward, the upper scraper swing cylinder 74 needs to be shortened synchronously to realize the downward movement of the upper scraper conveyor 7 and the upper loading device 8.

[0061] Furthermore, the upper loading device 8 includes an upper shovel plate 81, and two groups of upper discharge ports 811 distributed on the left and right are opened on the upper surface of the upper shovel plate 81. The front ends of the two groups of upper scraper conveyors 7 are located on the inner side of the upper discharge ports 811. The two sides and the rear side of the upper shovel plate 81 are fixedly connected with guard plates 82. The upper surface of the upper shovel plate 81 is rotatably connected with multiple groups of upper star wheels 83, and the multiple groups of upper star wheels 83 are symmetrically distributed on the left and right sides of the two groups of upper discharge ports 811. The lower surface of the upper shovel plate 81 is connected with an upper star wheel driving component 84 for driving the two adjacent groups of upper star wheels 83 on the same side longitudinally to rotate.

[0062] Specifically, the mineral material cut by the upper cutting drum 65 falls into the upper shovel plate 81. With the cooperation of multiple groups of upper star wheels 83 (preferably eight groups, the eight groups of upper star wheels 83 are symmetrically distributed on the left and right sides of the two groups of upper discharge ports 811, and the two groups of upper star wheels 83 on the same side are distributed longitudinally), the mineral material is quickly and efficiently guided into the upper discharge port 811 and transported to the upper scraper conveyor 7, avoiding the mineral material from falling into the lower area, thereby ensuring that the normal cutting work in the lower area will not be disturbed by the falling of the upper material. An upper star wheel 83 is provided on both sides of the upper discharge port 811 (the upper star wheel 83 on the left side of the upper discharge port 811 rotates clockwise, and the upper star wheel 83 on the right side of the upper discharge port 811 rotates counterclockwise).

[0063] Furthermore, the upper star wheel driving member 84 includes two groups of connecting shafts 841 and two groups of sprockets 842. The two groups of connecting shafts 841 are respectively fixedly connected to the lower ends of the rotating shafts of the two corresponding upper star wheels 83. The two groups of sprockets 842 are respectively fixedly sleeved on the outsides of the two groups of connecting shafts 841. The outer sides of the two groups of sprockets 842 are jointly meshed with a chain 843. The lower end of one group of connecting shafts 841 is fixedly connected to a driving motor 844. A protective cover 845 is fixedly sleeved on the outer side of the upper star wheel driving member 84.

[0064] Specifically, the driving motor 1 844 drives one set of connecting shafts 841 to rotate, and the connecting shafts 841 drive the outer sprocket 842 to rotate. At the same time, the sprocket 842 drives another set of sprockets 842 to rotate through the chain 843, thereby realizing the same-direction rotation of the two sets of upper star wheels 83.

[0065] Furthermore, the guide device 9 includes a funnel-shaped discharge bin 91, which is fixedly connected to the inner side of the discharge trough 21, and a discharge connecting pipe 92 is fixedly connected to the lower end of the discharge bin 91, and a discharge barrel 93 is fixedly connected to the lower end of the discharge connecting pipe 92. The discharge barrel 93 is arranged obliquely, and a discharge port 931 is penetrated through the lower surface of one end of the discharge barrel 93 away from the discharge connecting pipe 92, and the discharge port 931 is located directly above the main scraper conveyor 20. A spiral conveying auger 94 is rotatably connected to the interior of the discharge barrel 93, and a driving motor 941 for driving the spiral conveying auger 94 to rotate is fixedly connected to the front end of the discharge barrel 93.

[0066] Specifically, the upper scraper conveyor 7 transports and dumps the cut ore into the lower bin 91, and then enters the lower barrel 93 through the lower connecting pipe 92. The second drive motor 941 drives the spiral conveyor auger 94 to rotate, transporting the ore in the lower barrel 93 to the lower opening 931, and finally dropping from the lower opening 931 onto the main scraper conveyor 20, thereby realizing the continuous transmission and efficient processing of the ore.

[0067] Working principle: The first step is to control the lower cutting drum swing cylinder 33, the upper cutting drum swing cylinder 63 and the upper scraper swing cylinder 74 to extend. At this time, the lower cutting drum 35, the upper cutting drum 65 and the upper shovel plate 81 are all raised to the preset height (lifting the blade). The second step is to start the crawler walking device 12 and use its driving force to drive the whole machine forward until the lower cutting drum 35, the upper cutting drum 65 and the upper shovel plate 81 are close to the predetermined excavation surface, and after ensuring that the working surface is stable, the crawler walking device 12 stops operating. Then, the lower shovel plate 51 is controlled to descend through the shovel plate lifting cylinder 56. After the pressure between the lower shovel plate 51 and the ground reaches the required value, the rear stabilizer is dropped to make its pressure reach the set value. The third step is to start the lower star wheel 52, the lower scraper conveyor 4, the upper star wheel 83 and the upper scraper conveyor 7 to ensure that they are in a high-speed start-up state. At the same time, the lower cutting drum 35 and the upper cutting drum 65 are driven to start rotating to reach the preset speed. The fourth step is to start the cutting operation, control the lower cutting translation cylinder 16 and the upper cutting translation cylinder 66 to extend at the same time, so that the lower cutting drum 35 and the upper cutting drum 65 start cutting and feeding, until the lower cutting translation cylinder 16 and the upper cutting translation cylinder 66 reach the preset value, and stop feeding (feeding). Then, control the lower cutting drum swing cylinder 33 and the upper cutting drum swing cylinder 63 to slowly retract, so that the lower cutting drum 35 and the upper cutting drum 65 cut the rock downward, until they cut to the specified position and stop descending (cutting downward). In this process, the lower scraper conveyor 4, the lower loading device 5, the upper scraper conveyor 7 and the upper loading device 8 continue to operate efficiently, so as to efficiently transport the cut mineral materials. The fifth step is to start the bottom pulling and clearing operation, control the lower cutting translation cylinder 16 and the upper cutting translation cylinder 66 to retract at the same time, and control the upper cutting drum 65 drive seat to stop driving, so as to prepare for raising the knife again. The lower cutting drum 35 continues to operate, and the floating material on the bottom ground can be effectively cleaned by moving the lower cutting drum 35 backward (pulling the bottom). Step 6: After the bottom pulling is completed, the lower cutting drum drive seat 34 is controlled to stop driving, the lower cutting drum 35 stops rotating, the lower cutting drum swing cylinder 33, the upper cutting drum swing cylinder 63 and the upper scraper swing cylinder 74 are extended, and the blade is raised to a certain height, ready to enter the next cycle of cutting.

[0068] Example 2: Please refer to Figure 1-2 and Fig.17As another embodiment of the present invention, a protective device 10 is symmetrically connected to the left and right sides of the front of the frame top plate 2. The protective device 10 includes a protective plate 101. The rear side of the protective plate 101 is connected to multiple groups of elastic telescopic rods 102. The elastic telescopic rods 102 include an inner rod 1021 and a C-shaped rail 1022. The inner rod 1021 is fixedly connected to the rear side of the protective plate 101. The C-shaped rail 1022 is slidably connected to the outer side of the inner rod 1021. A spring 1023 is fixedly connected inside the C-shaped rail 1022. The rear end of the spring 1023 is fixedly connected to the inner side of the rear end of the C-shaped rail 1022. The front end of the spring 1023 is fixedly connected to the rear side of the inner rod 1021. The rear ends of the multiple groups of C-shaped rails 1022 are fixedly connected with a vertical plate 103, and a fixed block 104 is fixedly connected to the side of the vertical plate 103 close to the frame top plate 2. The left and right sides of the frame top plate 2 are fixedly connected with a protective plate translation cylinder 105, and the front end of the protective plate translation cylinder 105 is fixedly connected to the fixed block 104. The extension and shortening of the protective plate translation cylinder 105 can realize the forward and backward movement of the protective plate 101. The side of the fixed block 104 away from the vertical plate 103 is fixedly connected to a limiting slider 106. The left and right sides of the frame top plate 2 and in front of the protective plate translation cylinder 105 are symmetrically fixed with limiting slide rails 107 that slide in cooperation with the limiting slider 106.

[0069] Specifically, during the cutting operation, the protective plate translation cylinder 105 is extended, and the protective plate 101 is driven forward through the fixed block 104, the vertical plate 103, and the elastic telescopic rod 102, so that it abuts against the outer wall of the ore cross-section layer, thereby effectively preventing the ore from splashing during the cutting operation. When the cutting operation is completed, the protective plate translation cylinder 105 is controlled to shorten, and the protective plate 101 is brought back to its original position. In this process, the limit slider 106 slides in the limit slide rail 107, and the limit slide rail 107 plays a role in limiting and guiding the limit slider 106, thereby indirectly ensuring that the protective plate 101 can always move along the predetermined path. The function of the elastic telescopic rod 102 is to allow the protective plate 101 to automatically adjust its length when the equipment moves forward as a whole. When the protective plate 101 contacts the outer wall of the ore section layer, the inner rod 1021 will retract to a certain length inside the C-shaped rail 1022, and under the action of the spring 1023, the protective plate 101 always maintains good contact with the outer wall of the section layer, further ensuring the continuous stability of its protective effect.

[0070] It should be noted that: (1) The lower scraper conveyor 4, the upper scraper conveyor 7 and the main scraper conveyor 20 are respectively equipped with independent drive motors, and the installation position of the drive motor can be adjusted and installed according to the actual spatial position. The motor drive can realize their respective working functions, ensuring that each component can perform its respective tasks efficiently and stably during operation. (2) The transmission structure between the lower cutting drum drive seat 34 and the lower cutting drum 35, and the upper cutting drum drive seat 64 and the upper cutting drum 65 adopts the existing mature technical solutions, which have high stability and reliability. Therefore, this article will not elaborate on this part in detail to avoid repeated explanations. (3) In addition, the various groups of cylinders, motors and other electrical components mentioned in the article are connected to the power box 23 and the control terminal through electrical connections to form a complete electronic control system, through which precise control and coordinated operation of each working component can be achieved to ensure the normal operation and efficient performance of the overall equipment. (4) The equipment can be installed with various monitoring sensors and combined with big data processing technology to collect and analyze environmental and equipment status information in real time, support remote operation and intelligent control, and thus achieve efficient and accurate unmanned operation.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be regarded as within the scope of protection of the present invention.
