Description

Technical Field

[0001] This utility model belongs to the technical field of slope cutting machine devices, and relates to a mechanical shaving device for abandoned mine slopes. Background Technology

[0002] In the treatment of abandoned mine slopes, cutting operations are a crucial step in ensuring slope stability and eliminating potential geological hazards. Existing mine slope cutting equipment generally suffers from limited functionality: some equipment is only equipped with impact crushing structures, which, when processing soft rock, leads to excessive impact, resulting in energy waste, low efficiency, and potential damage to the surrounding rock structure; while equipment focused on soft rock scraping struggles to effectively crush hard rock. Furthermore, the operating angles of existing equipment are ill-suited to the complex and varied slope gradients, resulting in uneven cutting and increased subsequent repair costs and safety risks. Simultaneously, the equipment lacks stability and automation during operation, requiring frequent manual intervention, which not only reduces efficiency but also poses significant safety hazards. Therefore, there is an urgent need to design a mechanical cutting device for abandoned mine slopes that can overcome these shortcomings.

[0003] To overcome the shortcomings of existing technologies, people have continuously explored and proposed various solutions. For example, a Chinese patent discloses a slope-cutting machine for channel slopes [Application No.: 202221225070.3], which includes a traveling track laid along the channel direction on the bottom of the channel, a truss slidably connected to the traveling track, a first slope-cutting arm, a second slope-cutting arm, and a conveyor belt mechanism set on the first and second slope-cutting arms. The first and second slope-cutting arms are connected to both sides of the truss, and both the first and second slope-cutting arms are equipped with slope-cutting mechanisms. The slope-cutting mechanisms throw the soil generated by slope cutting to the conveyor belt mechanism, and the conveyor belt mechanism transports the soil to the top of the channel slope. However, this solution still cannot simultaneously possess the functions of impact crushing of hard rock and cutting of soft rock during slope cutting operations, resulting in low operating efficiency and high cost. Summary of the Invention

[0004] The purpose of this invention is to address the above-mentioned problems by providing a mechanical shaving device for abandoned mine slopes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A mechanical shaving device for abandoned mine slopes includes a shaving main base, within which is a swing arm base capable of reciprocating linear motion in the vertical direction and a height adjustment drive for driving the swing arm base to move up and down. A swing arm support body is mounted on the swing arm base, and a rotatable shaving swing arm is mounted on the swing arm support body. An impact-scraping dual-mode shaving mechanism is located at the bottom of the shaving swing arm. A locking auxiliary component is located within the swing arm support body, capable of reciprocating linear motion near or away from one end of the shaving swing arm. A lateral stone transport component is located in front of the swing arm support body.

[0007] In the aforementioned mechanical shaving device for abandoned mine slopes, the impact scraping dual-mode shaving mechanism includes a cutting tool mounting block located at the bottom of the shaving arm.

[0008] In the aforementioned mechanical shaving device for abandoned mine slopes, the adjustable impact crusher includes a drill bit fixing frame located at the front end of the cutting tool mounting block, on which a hard rock impact drill bit is fixed.

[0009] In the aforementioned mechanical shaving device for abandoned mine slopes, the adjustable soft rock scraper includes a cutter head fixing mold frame located at the rear end of the tool mounting block, on which a soft rock scraper head is fixed.

[0010] In the aforementioned mechanical squaring device for abandoned mine slopes, the horizontal height of the drill bit fixing mold is higher than the horizontal height of the cutter head fixing mold.

[0011] In the aforementioned mechanical squaring device for abandoned mine slopes, both the drill bit fixing frame and the cutter head fixing frame are driven by a worm gear mechanism.

[0012] In the aforementioned mechanical shaving device for abandoned mine slopes, the height adjustment drive component includes several hydraulic cylinders disposed within the shaving main seat. The power shaft of the hydraulic cylinders is connected to the swing arm base. Limiting anti-deviation blocks are provided on both sides of the swing arm base, and the limiting anti-deviation blocks are in sliding cooperation with the shaving main seat.

[0013] In the aforementioned mechanical squaring device for abandoned mine slopes, the locking auxiliary component includes a locking lever disposed within the swing arm support body. The locking lever is driven by a cylinder. The squaring swing arm is provided with a locking cavity that can engage with the locking lever. The squaring swing arm is driven and controlled by a motor, an electromagnetic clutch, and an electromagnetic brake.

[0014] In the aforementioned mechanical shaving device for abandoned mine slopes, the lateral transport component for crushed stone includes a crushed stone transport conveyor belt located in front of the swing arm support.

[0015] In the aforementioned mechanical shaving device for abandoned mine slopes, guide plates and retaining plates are respectively provided on both sides of the crushed stone conveyor belt.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] 1. This utility model, through the innovative design of a dual-mode cutting mechanism of cutting arm and impact scraping, realizes the flexible switching between impact crushing of hard rock and continuous scraping of soft rock, significantly improving the equipment's adaptability to different rock types, greatly increasing work efficiency. Furthermore, the dual-mode cutting mechanism of impact scraping can achieve multi-angle adjustment through a worm gear mechanism, accurately matching the slope gradient, ensuring the flatness and accuracy of the cutting operation, and reducing the difficulty of subsequent repairs.

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] like Figure 1-3As shown, a mechanical shaving device for abandoned mine slopes includes a shaving main base 1. The shaving main base 1 is provided with a swing arm base 2 that can reciprocate linearly in the vertical direction and a height adjustment drive component 3 for driving the swing arm base 2 to move up and down. The swing arm base 2 is provided with a swing arm support body 4. The swing arm support body 4 is provided with a rotatable shaving swing arm 5. The bottom of the shaving swing arm 5 is provided with an impact scraping dual-mode shaving mechanism 6. The swing arm support body 4 is provided with a locking auxiliary component 7 that can reciprocate linearly along one end close to or away from the shaving swing arm 5. The front of the swing arm support body 4 is provided with a stone crushing transverse transport component 8.

[0026] In this embodiment, the height of the swing arm support body 4 and the squaring swing arm 5 can be adjusted by the height adjustment drive component 3, which has strong adaptability. Through the innovative design of the squaring swing arm and the impact scraping dual-mode squaring mechanism, the flexible switching between hard rock impact crushing and soft rock continuous scraping can be realized, which significantly improves the equipment's adaptability to different rock types and greatly improves the work efficiency. Moreover, the impact scraping dual-mode squaring mechanism can achieve multi-angle adjustment through the worm gear mechanism to accurately match the slope gradient, ensure the flatness and accuracy of the squaring operation, and reduce the difficulty of subsequent repair. When the squaring swing arm 5 swings to the highest point and continues to move forward and backward, the squaring swing arm 5 is locked by the locking auxiliary component 7, which has strong stability. The crushed stone lateral transport component 8 installed in front of the swing arm support body 4 is responsible for receiving the crushed stone generated by the squaring operation and transporting it laterally to the designated position, which has a high degree of automation.

[0027] Combination Figure 1-3 As shown, the impact scraping dual-mode squaring mechanism 6 includes a cutting tool mounting block 9 disposed at the bottom of the squaring swing arm 5. An adjustable impact crusher 10 is mounted at the front end of the cutting tool mounting block 9, and an adjustable soft rock scraper 11 is mounted at the rear end of the cutting tool mounting block 9. The adjustable impact crusher 10 includes a drill bit fixing frame 12 disposed at the front end of the cutting tool mounting block 9, and a hard rock impact drill bit 13 is fixed on the drill bit fixing frame 12. The adjustable soft rock scraper 11 includes a cutter head fixing frame 14 disposed at the rear end of the cutting tool mounting block 9, and a soft rock scraping cutter head 144 is fixed on the cutter head fixing frame 14. Both the drill bit fixing frame 12 and the cutter head fixing frame 14 are driven by a worm gear mechanism 15.

[0028] In this embodiment, the drill bit fixing frame 12 of the adjustable impact crusher 10 is fixed to the front end of the cutting tool mounting block 9 by bolts, and the hard rock impact drill bit 13 is firmly installed on the drill bit fixing frame 12. The drill bit fixing frame 12 integrates a worm gear mechanism 15. The worm gear is coaxially connected to the drill bit fixing frame 12, and the worm is driven by a motor. When it is necessary to adjust the angle of the hard rock impact drill bit 13, the motor drives the worm to rotate, the worm drives the worm wheel to rotate, and then drives the drill bit fixing frame 12 and the hard rock impact drill bit 13 to rotate synchronously, so as to achieve precise angle adjustment. By adjusting the angle of the hard rock impact drill bit 13 through the worm gear mechanism 15, the hard rock impact drill bit 13 can always maintain the best impact angle when working on slopes with different slopes, give full play to its ability to crush hard rock, and improve crushing efficiency and quality.

[0029] The adjustable soft rock scraper 11 has its cutter head fixing frame 14 fixedly installed at the rear end of the tool mounting block 9. The soft rock scraper head 144 is installed on the cutter head fixing frame 14. Similar to the adjustable impact crusher 10, the cutter head fixing frame 14 is also driven by the worm gear mechanism 15. When it is necessary to adjust the angle of the soft rock scraper head 144, the worm gear mechanism 15 moves, driving the cutter head fixing frame 14 and the soft rock scraper head 144 to rotate, so that they match the slope gradient. The adjustable angle design of the soft rock scraper head 144 ensures that it can cut into the rock mass at the best angle during the scraping of soft rock, improve scraping efficiency, ensure the flatness of the cut surface, and reduce subsequent repair costs.

[0030] Combination Figure 1 As shown, the horizontal height of the drill bit fixing mold 12 is higher than the horizontal height of the cutter head fixing mold 14.

[0031] In this embodiment, by reasonably setting the height difference, the working performance of the two operating modes of impact crushing and scraping is optimized, ensuring that the two functional modules can play their best role under different operating conditions, while improving the safety and reliability of equipment operation.

[0032] The height adjustment drive component 3 includes several hydraulic cylinders 16 disposed in the squaring main seat 1. The power shaft of the hydraulic cylinder 16 is connected to the swing arm base 2. Limiting anti-deviation blocks 17 are provided on both sides of the swing arm base 2. The limiting anti-deviation blocks 17 are slidably engaged with the squaring main seat 1.

[0033] In this embodiment, the cooperation between the hydraulic cylinder 16 and the limiting anti-deviation block 17 enables precise and stable adjustment of the height of the swing arm base 2, which can quickly respond to the operational needs of different slope heights, while enhancing the overall stability of the equipment structure and improving operational safety.

[0034] Combination Figure 2As shown, the locking auxiliary component 7 includes a locking lever 18 disposed in the swing arm bracket body 4. The locking lever 18 is driven by a cylinder. The squaring swing arm 5 is provided with a locking cavity 19 that can engage with the locking lever 18. The squaring swing arm 5 is driven and controlled by a motor, an electromagnetic clutch and an electromagnetic brake.

[0035] In this embodiment, the drive system of the square-cutting swing arm 5 consists of a motor, an electromagnetic clutch, and an electromagnetic brake. The motor is connected to the rotating shaft of the square-cutting swing arm 5 through a transmission gear. The electromagnetic clutch is installed between the output shaft of the motor and the transmission gear, and the electromagnetic brake is installed on the rotating shaft of the square-cutting swing arm 5. During the upward movement of the square-cutting swing arm 5, the electromagnetic clutch is engaged, and the motor drives the square-cutting swing arm 5 to rotate through the transmission gear. When the square-cutting swing arm 5 reaches the designated position, the electromagnetic clutch disengages, cutting off the power connection between the motor and the swing arm. At the same time, the electromagnetic brake is immediately activated to brake and fix the square-cutting swing arm 5. Subsequently, the locking lever 18 is inserted into the locking cavity 19 for auxiliary fixation, realizing the precise positioning and stable fixation of the square-cutting swing arm 5 during operation. This effectively prevents the swing arm from shaking during impact or scraping operations, ensuring operational accuracy and safety, while also improving the automation control level of the equipment.

[0036] Combination Figure 1 As shown, the cross-sectional transport assembly 8 for crushed stone includes a crushed stone transport conveyor belt 20 disposed in front of the swing arm support body 4.

[0037] In this embodiment, the crushed stone conveyor belt 20 can transport the crushed stone generated by the cutting operation to the designated location in a timely and efficient manner, avoiding the accumulation of crushed stone from affecting the operation progress, keeping the work site clean, and improving the overall work efficiency.

[0038] Combination Figure 1 As shown, the crushed stone conveyor belt 20 is provided with guide plates 21 and stone retaining plates 22 on both sides.

[0039] In this embodiment, the setting of guide plate 21 and stone retaining plate 22 optimizes the path of crushed stone during transportation, ensures that crushed stone is stably transported on crushed stone conveyor belt 20, avoids crushed stone scattering causing environmental pollution or affecting operational safety, and further improves the reliability and efficiency of crushed stone transportation.

[0040] The working principle of this utility model is as follows:

[0041] Before carrying out slope cutting operations in abandoned mines, the hydraulic cylinder 16 in the height adjustment drive unit 3 is extended and retracted according to the actual height of the slope, pushing the swing arm base 2 to move up and down within the cutting main seat 1. This adjusts the cutting swing arm 5 and the impact scraping dual-mode cutting mechanism 6 to a suitable working height. The limit anti-deviation block 17 ensures the smooth movement of the swing arm base 2 and avoids deviation. When it is necessary to cut hard rock, the control system starts the motor, and the electromagnetic clutch on the motor output shaft is engaged. The motor drives the cutting swing arm 5 to swing backward through the transmission gear. During the swing arm swing, the control system monitors the swing arm angle in real time. When the cutting swing arm 5 swings to the preset hard rock breaking angle, the control system sends a signal to disengage the electromagnetic clutch and cut off the motor. The power connection to the squaring swing arm 5 is established. At this point, the squaring swing arm 5 stops swinging due to inertia. Immediately afterwards, the electromagnetic brake is activated, initially fixing the squaring swing arm 5. Then, the cylinder inside the swing arm support body 4 actuates, pushing the locking lever 18 into the locking cavity 19 inside the squaring swing arm 5, achieving double locking and ensuring that the squaring swing arm 5 remains stable. At this time, the hard rock impact drill bit 13 in the adjustable impact crusher 10 is aligned with the hard rock. According to the slope gradient, the angle of the drill bit fixing mold frame 12 is adjusted through the worm gear mechanism 15 so that the hard rock impact drill bit 13 contacts the hard rock at the optimal angle. The equipment starts the power system of the hard rock impact drill bit 13, and the hard rock impact drill bit 13 performs high-frequency impact crushing on the hard rock, breaking large pieces of hard rock into small pieces of gravel. The crushed gravel falls off. On the crushed stone conveyor belt 20 in front of the swing arm support body 4, the crushed stone is transported laterally to the designated position. When it is necessary to cut soft rock, the motor starts again, the electromagnetic clutch engages, and the cutting swing arm 5 is driven to rotate upward. When the cutting swing arm 5 rotates to the highest point and continues to move forward to the predetermined position, the control system first disengages the electromagnetic clutch to cut off the power transmission. Then, the electromagnetic brake is immediately activated to fix the cutting swing arm 5 in this position. Next, the cylinder pushes the locking lever 18 to insert into the locking cavity 19 to further enhance the stability of the swing arm. At this time, the soft rock scraper head 144 in the adjustable soft rock scraper 11 is in working condition. According to the slope, the worm gear mechanism 15 adjusts the cutter head fixing mold frame 14. The angle is adjusted so that the soft rock scraper head 144 fits against the soft rock surface. The control system releases the electromagnetic brake and pulls the locking lever 18 out of the locking cavity 19. The cutting arm 5 automatically falls under the action of gravity. The soft rock scraper head 144 contacts the soft rock and performs continuous scraping operation, cutting off the soft rock and forming gravel. This gravel also falls onto the gravel conveyor belt 20 and is transported to the designated position by the gravel conveyor belt 20. During the entire cutting operation, the guide plates 21 and the stone-blocking plates 22 on both sides of the gravel conveyor belt 20 continue to play their role. The guide plates 21 guide the gravel to fall smoothly onto the conveyor belt, and the stone-blocking plates 22 prevent the gravel from falling, ensuring that the gravel can be transported safely and efficiently, and ensuring the continuity of the cutting operation and the cleanliness of the site.
