At the same time, the requirements of environmental protection and sustainable development will also drive quarrying machines towards a greener and more environmentally friendly direction.

[0003] In existing technologies, after the cutting operation is completed in a quarry, the cutting part of the circular saw is prone to rusting due to contact with ore, moisture, and air. Therefore, a quarry machine capable of cutting raw ore has been proposed. Summary of the Invention

[0004] The present invention addresses the technical problem that, after the cutting operation of a circular saw in a mining quarry is completed, the cutting part is prone to rust due to contact with ore, moisture and air. The invention provides a mining quarry capable of cutting raw ore.

[0005] The technical solution adopted by this invention to solve its technical problem is: a quarrying machine capable of cutting raw ore, comprising a protective box, four first cylinders, four moving wheels, a cutting device, a rust prevention device, a protective device, and a controller.

[0006] The protective box is rectangular.

[0007] Four first cylinders are vertically symmetrically arranged on both sides of the protective box and fixedly connected to the side surface of the protective box.

[0008] Four movable wheels are respectively located below the four first cylinders and are connected to the lower end of the four first cylinders through support blocks.

[0009] The cutting device is mounted on a protective box and is used for cutting raw ore from the mine.

[0010] Rust prevention devices are installed on the protective box to prevent the cutting tools from being damaged by rust.

[0011] The protective device is installed on the protective box to prevent the rust prevention device from being damaged during cutting operations.

[0012] The controller is mounted on the side surface of the protective box and is fixedly connected to the side surface of the protective box. It is electrically connected to the four first cylinders and to the cutting device.

[0013] When it is necessary to cut the raw ore, the workers start the cutting device through the controller to cut the raw ore. The start of the cutting device activates the anti-rust device, which can evenly spray anti-rust oil onto the cutting part of the blade, forming a protective film on the cutting part of the blade. This isolates the cutting part from air, moisture and corrosive substances in the stone, reduces oxidation and corrosion, and extends the service life of the blade. The start of the cutting device also activates the protective device, which can prevent the anti-rust device from being damaged during the cutting operation.

[0014] Furthermore, the cutting device includes two support plates, a housing, a cutting hole, two rotating rods, a circular saw, a motor, and a second cylinder.

[0015] Two support plates are symmetrically arranged horizontally inside the protective box. One end of each support plate is slidably connected to the inner side of the protective box, and the sliding direction is vertical.

[0016] The outer shell is concave and faces downward. The outer shell is fan-shaped and vertically arranged, perpendicular to the front of the protective box. The outer shell is set between two support plates, and the two side surfaces of the outer shell are fixedly connected to the other end of the two support plates respectively.

[0017] The cutting hole is elongated and perpendicular to the front of the protective box. The cutting hole is located at the bottom of the protective box and directly below the outer shell. The upper end of the cutting hole is connected to the inside of the protective box, and the lower end is connected to the bottom.

[0018] The two rotating rods are arranged horizontally, parallel to the front of the protective box. The two rotating rods are symmetrically arranged inside the outer shell, and one end of each rotating rod is rotatably connected to the inner side of the outer shell. Their rotation axis coincides with their own axis.

[0019] The circular saw's axis is set horizontally, coinciding with the axes of the two rotating rods. The lower half of the circular saw passes through the cutting hole and extends to the bottom of the protective box, while the upper half is set inside the outer casing. The two sides of the circular saw are fixedly connected to the other ends of the two rotating rods, respectively.

[0020] The motor is located below the two support plates. The motor shaft axis is set horizontally and coincides with the axis of the circular saw. The motor shaft passes through the side of the housing and is fixedly connected to the rotating rod. The motor is fixedly connected to the side surface of the housing and electrically connected to the controller.

[0021] The second cylinder is vertically oriented and positioned below the support plate and close to the motor. The lower end of the second cylinder is fixedly connected to the bottom surface inside the protective box, and the upper end is fixedly connected to the lower surface of the support plate. The second cylinder is electrically connected to the controller.

[0022] When it is necessary to cut the raw ore, the workers push the protective box to the position of the ore to be mined. Then, the workers activate the four first cylinders through the controller. The first cylinders retract and move the protective box downwards until it reaches the designated height, in preparation for the subsequent cutting operation of the raw ore.

[0023] The worker then activates the second cylinder via the controller. The second cylinder retracts, causing the right support plate to move downwards. This downward movement of the right support plate causes the outer casing to move downwards, which in turn causes the two rotating rods to move downwards. The two rotating rods then move downwards, causing the circular saw to move downwards until it contacts the surface of the ore. At this point, the worker activates the motor via the controller. The motor's rotation causes the right rotating rod to rotate, which in turn causes the circular saw to rotate. The circular saw then moves downwards, thus cutting the ore.

[0024] Furthermore, a switch door is provided on the side of the protective box.

[0025] The addition of a switchable door facilitates maintenance of the interior of the protective box by staff.

[0026] Furthermore, the outer casing coincides with the axis of the circular saw.

[0027] Furthermore, the rust prevention device includes an oil reservoir, a transfer box, a sliding plate, a limiting plate, a support rod, a first magnet, a second magnet, an oil inlet pipe, an oil outlet tank, an oil outlet pipe, and two nozzles.

[0028] The top of the oil tank is covered, and the oil tank is located inside the bottom of the protective box, behind the second cylinder, and is fixedly connected to the bottom of the protective box.

[0029] The bottom of the transfer box is open. The transfer box is located on the top surface inside the protective box and directly above the second cylinder. The transfer box is fixedly connected to the top surface inside the protective box.

[0030] The slide plate is horizontally positioned inside the conveyor box and is sealed and slidably connected to the inner wall of the conveyor box, with its sliding direction set vertically.

[0031] The limiting plate is square ring shaped and is set inside the conveyor box, below the slide plate. The limiting plate is fixedly connected to the inner side of the conveyor box.

[0032] The support rod is vertically positioned between the slide plate and the support plate, with its lower end fixedly connected to the upper surface of the support plate.

[0033] The first magnet is located at the upper end of the support rod and is fixedly connected to the upper end of the support rod.

[0034] The lower end of the second magnet is of opposite polarity to the upper end of the first magnet. The second magnet is positioned below the skateboard and corresponds to the position of the first magnet. The second magnet is fixedly connected to the lower surface of the skateboard.

[0035] A one-way valve is fixedly connected in the middle of the oil inlet pipe. One end of the oil inlet pipe is connected to the bottom of the oil storage tank, and the other end is connected to the top of the transfer box.

[0036] The oil outlet tank is cylindrical with its axis set vertically. The oil outlet tank is located directly behind the circular saw and is fixedly connected to the bottom of the protective box.

[0037] A one-way valve is fixedly connected in the middle of the oil outlet pipe. One end of the oil outlet pipe is connected to the top of the oil tank, and the other end is connected to the top of the transfer box.

[0038] Two nozzles are located on the side of the oil outlet tank and face the circular saw. One end of each nozzle is connected to the inside of the protective box, and the other end is connected to the inside of the oil outlet tank.

[0039] When the support plate on the right moves downward, it causes the support rod to move downward, which in turn causes the first magnet to move downward. The first magnet then causes the second magnet to move downward, which in turn causes the slide plate to move downward. The downward movement of the slide plate allows the rust-preventive oil in the oil tank to enter the conveyor box through the oil inlet pipe, preparing for the subsequent rust-preventive operation on the circular saw.

[0040] When the skateboard moves downwards and comes into contact with the limiting plate, the first magnet continues to move downwards, separating from the second magnet to prevent the skateboard from detaching from the conveyor box and causing the anti-rust oil to leak.

[0041] When the support plate on the right moves upward, it drives the support rod upward, which in turn drives the first magnet upward. When the circular saw separates from the surface of the raw stone, the first magnet and the second magnet come into contact. Subsequently, the first magnet moves upward, driving the second magnet upward, which in turn drives the slide plate upward. The upward movement of the slide plate causes the rust-preventive oil in the conveyor box to pass through the oil outlet pipe and oil tank in sequence, and finally through the filter screens in the two nozzles and be sprayed onto the circular saw. This forms a protective film on the cutting part of the circular saw, isolating it from air, moisture, and corrosive substances in the stone, reducing oxidation and corrosion, and extending the service life of the circular saw.

[0042] Furthermore, filters are fixedly connected to the oil inlets of the two nozzles.

[0043] By installing a filter, dust is prevented from entering the oil tank.

[0044] Furthermore, a push handle is fixedly connected to the side surface of the protective box.

[0045] The addition of a push handle makes it easier for staff to move the protective box.

[0046] Furthermore, the protective device includes a protective cylinder, an oil outlet, a movable plate, a screw, a ring rack, and gears.

[0047] The protective cylinder has a vertical axis that coincides with the axis of the oil outlet tank. Both ends of the protective cylinder are open. The protective cylinder is fitted outside the oil outlet tank and is rotatably connected to the bottom surface inside the protective tank. Its rotation axis is vertical.

[0048] The oil outlet is arc-shaped and located on the side of the protective cylinder, away from the oil storage tank. One end of the oil outlet is connected to the inside of the protective cylinder, and the other end is connected to the inside of the protective cylinder. The width of the oil outlet is matched with the two nozzles.

[0049] The movable plate is located on the side of the protective cylinder away from the oil storage tank. The movable plate is horizontally positioned behind the support plate, fixedly connected to the side surface of the support plate, and slidably connected to the inner side of the protective box. Its sliding direction is vertical.

[0050] The screw is vertically positioned on the side of the protective cylinder away from the oil tank. The upper end of the screw is rotatably connected to the top surface inside the protective cylinder, and its rotation axis is vertically positioned. The lower end penetrates downward through the moving plate and is rotatably connected to the bottom surface inside the protective cylinder, and its rotation axis is vertically positioned. The screw is threadedly connected to the moving plate.

[0051] The annular rack is vertically oriented and coincides with the axis of the protective cylinder. The annular rack is sleeved outside the protective cylinder and located below the oil outlet. The annular rack is fixedly connected to the side surface of the protective cylinder.

[0052] The gear axis is vertically positioned and coincides with the screw axis. The gear is sleeved outside the screw and located on the side of the ring rack. The gear is fixedly connected to the side surface of the screw and meshes with the ring rack.

[0053] When the outer casing moves downward, it causes the left support plate to move downward, which in turn causes the moving plate to move downward. The moving plate then causes the screw to rotate, which in turn causes the gear to rotate. The gear then causes the ring rack to rotate, which in turn causes the protective cylinder to rotate. The protective cylinder then causes the oil outlet to rotate. When the circular saw comes into contact with the ground, the oil outlet is now away from the two nozzles, thus preventing some of the broken stone from hitting the two nozzles and damaging them during the cutting operation of the circular saw on the ore.

[0054] When the outer casing moves upward, it causes the left support plate to move upward, which in turn causes the moving plate to move upward. The moving plate then causes the screw to rotate, which in turn causes the gear to rotate. The gear then causes the ring rack to rotate, which in turn causes the protective cylinder to rotate. The rotation of the protective cylinder causes the oil outlet to rotate. When the circular saw separates from the surface of the ore, the oil outlet is in front of the two nozzles, and the two nozzles begin to spray rust-preventive oil onto the cutting part of the circular saw until the spraying operation is completed. The oil outlet remains in front of the two nozzles throughout the process, thus preventing rust-preventive oil from being sprayed onto the inner wall of the protective cylinder and wasting it.

[0055] Furthermore, a toolbox is fixedly connected to the bottom of the inside of the protective box.

[0056] By providing a toolbox, maintenance work can be carried out more easily by staff.

[0057] Furthermore, the circular saw is made of carbide material.

[0058] Hard alloys have good hardness, heat resistance and wear resistance.

[0059] The beneficial effects of this invention are:

[0060] 1. This invention, through the interaction and mutual support of the cutting device and the anti-rust device, can evenly spray anti-rust oil onto the cutting part of the circular saw after the cutting operation is completed, so that a protective film is formed on the cutting part of the circular saw, isolating air, moisture and corrosive substances in the stone, reducing oxidation and corrosion, and extending the service life of the circular saw.

[0061] 2. The present invention, through the interaction and mutual support of the cutting device and the protective device, can prevent the circular saw from damaging the two nozzles when some stone fragments hit the two nozzles during the cutting operation of the raw ore.

[0066] The following will describe the concept and technical effects of the present invention clearly and completely with reference to the embodiments, so as to fully understand the purpose, features and effects of the present invention.

[0067] A preferred embodiment of the quarrying machine capable of cutting raw ore provided by the present invention is as follows: Figures 1 to 3 As shown: A quarrying machine capable of cutting ore from mines includes a protective box 1, four first cylinders 2, four moving wheels 3, a cutting device, a rust prevention device, a protective device, and a controller.

[0068] The protective box 1 is a cuboid.

[0069] Four first cylinders 2 are vertically symmetrically arranged on both sides of the protective box 1 and are fixedly connected to the side surface of the protective box 1.

[0070] Four movable wheels 3 are respectively located below the four first cylinders 2, and are respectively connected to the lower end of the four first cylinders 2 through support blocks.

[0071] The cutting device is installed on the protective box 1 and is used for cutting raw ore from the mine.

[0072] The rust prevention device is installed on the protective box 1 to prevent the cutting tool from being damaged by rust.

[0073] The protective device is installed on the protective box 1 to prevent the rust prevention device from being damaged during the cutting operation.

[0074] The controller is located on the side surface of the protective box 1 and is fixedly connected to the side surface of the protective box 1. It is electrically connected to the four first cylinders 2 and to the cutting device.

[0075] When it is necessary to cut the raw ore, the workers start the cutting device through the controller to cut the raw ore. The start of the cutting device activates the anti-rust device, which can evenly spray anti-rust oil onto the cutting part of the blade, forming a protective film on the cutting part of the blade. This isolates the cutting part from air, moisture and corrosive substances in the stone, reduces oxidation and corrosion, and extends the service life of the blade. The start of the cutting device also activates the protective device, which can prevent the anti-rust device from being damaged during the cutting operation.

[0076] The cutting device includes two support plates 401, a housing 402, a cutting hole, two rotating rods 403, a circular saw 404, a motor 405, and a second cylinder 406.

[0077] Two support plates 401 are arranged symmetrically in the inner side of the protective box 1. One end of the two support plates 401 is slidably connected to the inner side of the protective box 1, and the sliding direction is set vertically.

[0078] The outer shell 402 is concave and faces downward. The outer shell 402 is fan-shaped and vertically arranged, perpendicular to the front of the protective box 1. The outer shell 402 is arranged between two support plates 401, and the two side surfaces of the outer shell 402 are fixedly connected to the other end of the two support plates 401 respectively.

[0079] The cutting hole is elongated and perpendicular to the front of the protective box 1. The cutting hole is located at the bottom of the protective box 1 and directly below the outer shell 402. The upper end of the cutting hole is connected to the inside of the protective box 1, and the lower end is connected to the bottom.

[0080] The axes of the two rotating rods 403 are arranged laterally and parallel to the front of the protective box 1. The two rotating rods 403 are symmetrically arranged inside the outer shell 402. One end of the two rotating rods 403 is rotatably connected to the inner side of the outer shell 402, and their rotation axis coincides with their own axis.

[0081] The circular saw 404 has its axis set horizontally, coinciding with the axes of the two rotating rods 403. The lower half of the circular saw 404 passes through the cutting hole and extends to the bottom of the protective box 1, while the upper half is set inside the outer shell 402. The two sides of the circular saw 404 are fixedly connected to the other ends of the two rotating rods 403 respectively.

[0082] The motor 405 is located below the two support plates 401. The axis of the motor 405 is set horizontally and coincides with the axis of the circular saw 404. The motor 405 shaft passes through the side of the housing 402 and is fixedly connected to the rotating rod 403. The motor 405 is fixedly connected to the side surface of the housing 402 and electrically connected to the controller.

[0083] The second cylinder 406 is vertically oriented and positioned below the support plate 401 and close to the motor 405. The lower end of the second cylinder 406 is fixedly connected to the bottom surface inside the protective box 1, and the upper end is fixedly connected to the lower surface of the support plate 401. The second cylinder 406 is electrically connected to the controller.

[0084] When it is necessary to cut the raw ore, the staff pushes the protective box 1 to the position of the ore to be mined. Then, the staff activates the four first cylinders 2 through the controller. The first cylinders 2 contract and drive the protective box 1 to move downward until the protective box 1 moves down to the designated height, in preparation for the subsequent cutting operation of the raw ore.

[0085] Then, the staff activates the second cylinder 406 via the controller. The second cylinder 406 retracts, causing the right support plate 401 to move downwards. The downward movement of the right support plate 401 causes the outer casing 402 to move downwards. The downward movement of the outer casing 402 causes the two rotating rods 403 to move downwards. The downward movement of the two rotating rods 403 causes the circular saw 404 to move downwards until the circular saw 404 contacts the surface of the ore. At this point, the staff activates the motor 405 via the controller. The rotation of the motor 405 causes the right rotating rod 403 to rotate. The rotation of the right rotating rod 403 causes the circular saw 404 to rotate. At this point, the circular saw 404 moves downwards, thus performing the cutting operation on the ore.

[0086] The protective box 1 has a switch door on its side.

[0087] The installation of a switch door facilitates maintenance of the interior of the protective box 1 by staff.

[0088] The axis of the outer casing 402 coincides with that of the circular saw 404.

[0089] The rust prevention device includes an oil reservoir 501, a transfer box 502, a sliding plate 503, a limiting plate 504, a support rod 505, a first magnet 506, a second magnet 507, an oil inlet pipe 508, an oil outlet tank 509, an oil outlet pipe 510, and two nozzles 511.

[0090] The top of the oil tank 501 is covered. The oil tank 501 is located on the bottom surface inside the protective box 1 and is located behind the second cylinder 406. It is fixedly connected to the bottom surface inside the protective box 1.

[0091] The bottom of the transfer box 502 is open. The transfer box 502 is located on the top surface inside the protective box 1 and is directly above the second cylinder 406. The transfer box 502 is fixedly connected to the top surface inside the protective box 1.

[0092] The slide plate 503 is horizontally arranged inside the conveyor box 502 and is slidably connected to the inner wall of the conveyor box 502. Its sliding direction is vertical.

[0093] The limiting plate 504 is in the shape of a square ring. The limiting plate 504 is set inside the conveyor box 502 and below the slide plate 503. The limiting plate 504 is fixedly connected to the inner side of the conveyor box 502.

[0094] The support rod 505 is vertically positioned between the slide plate 503 and the support plate 401, and the lower end of the support rod 505 is fixedly connected to the upper surface of the support plate 401.

[0095] The first magnet 506 is disposed on the upper end of the support rod 505 and is fixedly connected to the upper end of the support rod 505.

[0096] The lower end of the second magnet 507 is of opposite polarity to the upper end of the first magnet 506. The second magnet 507 is positioned below the slide plate 503 and corresponds to the position of the first magnet 506. The second magnet 507 is fixedly connected to the lower surface of the slide plate 503.

[0097] A one-way valve is fixedly connected to the middle of the oil inlet pipe 508. One end of the oil inlet pipe 508 is connected to the bottom of the oil storage tank 501, and the other end is connected to the top of the transfer box 502.

[0098] The oil outlet tank 509 is a cylinder with its axis set vertically. The oil outlet tank 509 is located directly behind the circular saw 404 and is fixedly connected to the bottom surface inside the protective box 1.

[0099] A one-way valve is fixedly connected to the middle of the oil outlet pipe 510. One end of the oil outlet pipe 510 is connected to the top of the oil outlet tank 509, and the other end is connected to the top of the transfer box 502.

[0100] Two nozzles 511 are located on the side of the oil outlet tank 509 and face the circular saw 404. One end of the two nozzles 511 is connected to the inside of the protective box 1, and the other end is connected to the inside of the oil outlet tank 509.

[0101] When the support plate 401 on the right moves downward, it causes the support rod 505 to move downward. The downward movement of the support rod 505 causes the first magnet 506 to move downward. The downward movement of the first magnet 506 causes the second magnet 507 to move downward. The downward movement of the second magnet 507 causes the slide plate 503 to move downward. The downward movement of the slide plate 503 allows the rust-preventive oil in the oil tank 501 to enter the conveyor box 502 through the oil inlet pipe 508, preparing for the subsequent rust-preventive operation on the circular saw 404.

[0102] When the slide plate 503 moves downward and comes into contact with the limiting plate 504, the first magnet 506 continues to move downward and separates from the second magnet 507, preventing the slide plate 503 from detaching from the conveyor box 502 and causing the anti-rust oil to leak.

[0103] When the support plate 401 on the right moves upward, it drives the support rod 505 to move upward. The support rod 505 then drives the first magnet 506 to move upward. When the circular saw 404 separates from the surface of the raw stone, the first magnet 506 and the second magnet 507 come into contact. Subsequently, the first magnet 506 moves upward, driving the second magnet 507 to move upward. The second magnet 507 then drives the slide plate 503 to move upward. The upward movement of the slide plate 503 causes the rust-preventive oil in the conveyor box 502 to pass through the oil outlet pipe 510 and the oil tank 509 in sequence, and finally be sprayed onto the circular saw 404 through the filter screens in the two nozzles 511. This forms a protective film on the cutting part of the circular saw 404, isolating it from air, moisture, and corrosive substances in the stone, reducing oxidation and corrosion, and extending the service life of the circular saw 404.

[0104] Each of the two nozzles 511 has a filter screen fixedly connected inside its oil inlet.

[0105] By installing a filter screen, dust is prevented from entering the oil outlet tank 509.

[0106] A push handle is fixedly connected to one side surface of the protective box.

[0107] The push handle makes it easy for staff to push the protective box 1.

[0108] The protective device includes a protective cylinder 601, an oil outlet, a movable plate 602, a screw 603, a ring rack 604, and a gear 605.

[0109] The protective cylinder 601 is vertically oriented and coincides with the axis of the oil outlet tank 509. Both ends of the protective cylinder 601 are open. The protective cylinder 601 is sleeved outside the oil outlet tank 509 and is rotatably connected to the bottom surface inside the protective box 1. Its rotation axis is vertically oriented.

[0110] The oil outlet is arc-shaped and is located on the side of the protective cylinder 601, on the side of the oil tank 509 away from the oil storage tank 501. One end of the oil outlet is connected to the inside of the protective box 1, and the other end is connected to the inside of the protective cylinder 601. The width of the oil outlet is matched with the two nozzles 511.

[0111] The movable plate 602 is located on the side of the protective cylinder 601 away from the oil storage tank 501. The movable plate 602 is horizontally located behind the support plate 401, fixedly connected to the side surface of the support plate 401, and slidably connected to the inner side of the protective box 1. Its sliding direction is vertical.

[0112] The screw 603 is vertically positioned on the side of the protective cylinder 601 away from the oil storage tank 501. The upper end of the screw 603 is rotatably connected to the top surface inside the protective box 1, and its rotation axis is set vertically. The lower end penetrates downward through the moving plate 602 and is rotatably connected to the bottom surface inside the protective box 1, and its rotation axis is set vertically. The screw 603 is threadedly connected to the moving plate 602.

[0113] The annular rack 604 is vertically oriented and coincides with the axis of the protective cylinder 601. The annular rack 604 is sleeved on the outside of the protective cylinder 601 and located below the oil outlet. The annular rack 604 is fixedly connected to the side surface of the protective cylinder 601.

[0114] The gear 605 is vertically oriented and coincides with the axis of the screw 603. The gear 605 is sleeved on the outside of the screw 603 and is located on the side of the annular rack 604. The gear 605 is fixedly connected to the side surface of the screw 603 and meshes with the annular rack 604.

[0115] When the outer casing 402 moves downward, it causes the left support plate 401 to move downward. The downward movement of the left support plate 401 causes the moving plate 602 to move downward. The downward movement of the moving plate 602 causes the screw 603 to rotate. The rotation of the screw 603 causes the gear 605 to rotate. The rotation of the gear 605 causes the ring rack 604 to rotate. The rotation of the ring rack 604 causes the protective cylinder 601 to rotate. The rotation of the protective cylinder 601 causes the oil outlet to rotate. When the circular saw 404 contacts the ground, the oil outlet is away from the two nozzles 511, thus preventing some of the broken stone from hitting the two nozzles 511 and causing damage to the two nozzles 511 when the circular saw 404 is cutting the raw ore.

[0116] When the outer casing 402 moves upward, it causes the left support plate 401 to move upward. The left support plate 401 moves upward, causing the moving plate 602 to move upward. The moving plate 602 moves upward, causing the screw 603 to rotate. The screw 603 rotates, causing the gear 605 to rotate. The gear 605 rotates, causing the ring rack 604 to rotate. The ring rack 604 rotates, causing the protective cylinder 601 to rotate. The protective cylinder 601 rotates, causing the oil outlet to rotate. When the circular saw 404 separates from the surface of the ore, the oil outlet is in front of the two nozzles 511. The two nozzles 511 begin to spray rust-preventive oil onto the cutting part of the circular saw 404 until the spraying operation is completed. The oil outlet is always in front of the two nozzles 511, thus avoiding the rust-preventive oil from being sprayed on the inner wall of the protective cylinder 601, which would cause waste.

[0117] A toolbox is fixedly connected to the bottom of the interior of the protective box 1.

[0118] By providing a toolbox, maintenance work can be carried out more easily by staff.

[0119] The 404 circular saw is made of cemented carbide material.

[0120] Hard alloys have good hardness, heat resistance and wear resistance.

[0121] Working principle: When it is necessary to cut the raw ore, the staff pushes the protective box 1 with the push handle and pushes the protective box 1 to the position of the ore to be mined. Then the staff opens the four first cylinders 2 through the controller. The first cylinders 2 retract and drive the protective box 1 to move downward until the protective box 1 moves down to the designated height, in preparation for the subsequent cutting operation of the raw ore.

[0122] Then, the staff activated the second cylinder 406 through the controller. The second cylinder 406 retracted, causing the right support plate 401 to move downward. The downward movement of the right support plate 401 in turn caused the outer shell 402 and the support rod 505 to move downward in sequence.

[0123] When the support plate 401 on the right moves downward, it causes the support rod 505 to move downward. The support rod 505 moves downward, causing the first magnet 506 to move downward. The first magnet 506 moves downward, causing the second magnet 507 to move downward. The second magnet 507 moves downward, causing the slide plate 503 to move downward. The slide plate 503 moves downward, allowing the rust-preventive oil in the oil tank 501 to enter the conveyor box 502 through the oil inlet pipe 508, preparing for the subsequent rust-preventive operation on the circular saw 404.

[0124] When the slide plate 503 moves downward and comes into contact with the limiting plate 504, the first magnet 506 continues to move downward. The first magnet 506 moves downward and separates from the second magnet 507, preventing the slide plate 503 from detaching from the conveyor box 502 and causing the anti-rust oil to leak.

[0125] When the right support plate 401 moves downward, causing the outer shell 402 to move downward, the downward movement of the outer shell 402 in turn causes the left support plate 401 and the two rotating rods 403 to move downward in sequence.

[0126] When the outer casing 402 moves downward, it drives the two rotating rods 403 to move downward. The two rotating rods 403 move downward, which in turn drives the circular saw 404 to move downward until the circular saw 404 contacts the surface of the ore. At this time, the operator turns on the motor 405 through the controller. The motor 405 rotates, which drives the right rotating rod 403 to rotate. The right rotating rod 403 rotates, which in turn drives the circular saw 404 to rotate. At this time, the circular saw 404 moves downward, thereby cutting the ore.

[0127] When the outer casing 402 moves downward, it causes the left support plate 401 to move downward. The left support plate 401 moves downward, causing the moving plate 602 to move downward. The moving plate 602 moves downward, causing the screw 603 to rotate. The screw 603 rotates, causing the gear 605 to rotate. The gear 605 rotates, causing the ring rack 604 to rotate. The ring rack 604 rotates, causing the protective cylinder 601 to rotate. The protective cylinder 601 rotates, causing the oil outlet to rotate. When the circular saw 404 contacts the ground, the oil outlet is away from the two nozzles 511, thus preventing some of the broken stone from hitting the two nozzles 511 and causing damage to the two nozzles 511 when the circular saw 404 is cutting the raw ore.

[0128] After the cutting operation is completed, the worker opens the second cylinder 406 through the controller. The second cylinder 406 extends and drives the right support plate 401 to move upward. The upward movement of the right support plate 401 drives the outer shell 402 and the support rod 505 to move upward in sequence.

[0129] When the support plate 401 on the right moves upward, it drives the support rod 505 to move upward. The support rod 505 moves upward, which in turn drives the first magnet 506 to move upward. When the circular saw 404 separates from the surface of the raw stone, the first magnet 506 and the second magnet 507 come into contact. Then, the first magnet 506 moves upward, which drives the second magnet 507 to move upward. The second magnet 507 moves upward, which drives the slide plate 503 to move upward. The slide plate 503 moves upward, which causes the anti-rust oil in the conveyor box 502 to pass through the oil outlet pipe 510 and the oil outlet tank 509 in sequence, and finally through the filter screen in the two nozzles 511 to spray onto the circular saw 404. This forms a protective film on the cutting part of the circular saw 404, isolating it from air, moisture and corrosive substances in the stone, reducing oxidation and corrosion, and extending the service life of the circular saw 404.

[0130] When the right support plate 401 moves upward, causing the outer shell 402 to move upward, the upward movement of the outer shell 402 in turn causes the left support plate 401 and the two rotating rods 403 to move upward in sequence.

[0131] When the outer casing 402 moves upward, it drives the two rotating rods 403 to move upward. The two rotating rods 403 then move upward, driving the circular saw 404 to move upward until the circular saw 404 separates from the surface of the raw stone. At this point, the operator starts the motor 405 through the controller, causing the motor 405 shaft to rotate slowly. The slow rotation of the motor 405 shaft drives the right rotating rod 403 to rotate slowly, which in turn drives the circular saw 404 to rotate slowly, thus ensuring that the anti-rust oil can be evenly sprayed on the cutting part of the circular saw 404.

[0132] When the outer casing 402 moves upward, it causes the left support plate 401 to move upward. The left support plate 401 moves upward, causing the moving plate 602 to move upward. The moving plate 602 moves upward, causing the screw 603 to rotate. The screw 603 rotates, causing the gear 605 to rotate. The gear 605 rotates, causing the ring rack 604 to rotate. The ring rack 604 rotates, causing the protective cylinder 601 to rotate. The protective cylinder 601 rotates, causing the oil outlet to rotate. When the circular saw 404 separates from the surface of the ore, the oil outlet is in front of the two nozzles 511. The two nozzles 511 begin to spray rust-preventive oil onto the cutting part of the circular saw 404 until the spraying operation is completed. The oil outlet is always in front of the two nozzles 511, thus avoiding the rust-preventive oil from being sprayed on the inner wall of the protective cylinder 601, which would cause waste.

[0133] When the transmission components inside the protective box 1 malfunction, the staff can promptly open the switch door of the protective box 1 and take out the repair tools from the toolbox to repair it.

[0134] The above embodiments are only some embodiments of the present invention, and not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are all within the scope of protection of the present invention.
