The protective box is a rectangular parallelepiped.

[0006] The four first cylinders are vertically symmetrically arranged on both sides of the protection box and are fixedly connected to the side surface of the protection box.

[0007] The four moving wheels are respectively arranged under the four first cylinders and are respectively connected to the lower ends of the four first cylinders through supporting blocks.

[0008] The cutting device is arranged on the protective box and is used for cutting the raw stones in the mine.

[0009] The anti-rust device is arranged on the protection box to prevent the cutting tool from being damaged due to rust.

[0010] The protective device is arranged on the protective box to prevent the anti-rust device from being damaged during cutting operation.

[0011] The controller is arranged on the side surface of the protective box, fixedly connected to the side surface of the protective box, electrically connected to the four first cylinders, and electrically connected to the cutting device.

[0012] When it is necessary to perform cutting operations on the mine raw stones, the staff turns on the cutting device through the controller, so as to cut the mine raw stones. When the cutting device starts, it drives the rust prevention device, which can evenly spray the rust prevention oil on the cutting part of the tool, forming a protective film on the cutting part of the tool, isolating air, moisture and corrosive substances in the stone, reducing the occurrence of oxidation and corrosion, and extending the service life of the tool. When the cutting device starts, it drives the protection device, which can prevent the rust prevention device from being damaged during the cutting operation.

[0013] 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. The two support plates are symmetrically arranged horizontally inside the protective box. One end of the two support plates is slidably connected to the inner side surface of the protective box, and its sliding direction is vertically arranged.

[0014] The housing is concave and faces downward. The housing is fan-shaped, vertically arranged, perpendicular to the front of the protective box. The housing is arranged between the two support plates, and the two side surfaces of the housing are respectively fixedly connected to the other ends of the two support plates.

[0015] The cutting hole is strip-shaped, perpendicular to the front of the protective box. The cutting hole is arranged at the bottom of the protective box and is directly below the housing. The upper end of the cutting hole is communicated with the inside of the protective box, and the lower end is communicated with the lower part.

[0016] The axes of the two rotating rods are horizontally arranged, parallel to the front of the protective box. The two rotating rods are symmetrically arranged inside the housing. One end of the two rotating rods is rotatably connected to the inner side surface of the housing, and its rotation axis coincides with its own axis.

The second cylinder is electrically connected to the controller.

[0020] When it is necessary to cut the original ore in the mine, the staff push the protective box and move the protective box to the position of the ore to be mined. Subsequently, the staff turn on four first cylinders through the controller. The contraction of the first cylinders drives the protective box to move downward until the protective box moves downward to the specified height, preparing for the subsequent cutting operation of the original ore in the mine.

[0021] Subsequently, the staff turn on the second cylinder through the controller. The contraction of the second cylinder drives the right support plate to move downward. The downward movement of the right support plate drives the housing to move downward. The downward movement of the housing drives the two rotating rods to move downward. The downward movement of the two rotating rods drives the circular saw to move downward until the circular saw contacts the surface of the original ore in the mine. At this time, the staff turn on the motor through the controller. The rotation of the motor drives the right rotating rod to rotate. The rotation of the right rotating rod drives the circular saw to rotate. At this time, the circular saw moves downward, thereby cutting the original ore in the mine.

[0022] Furthermore, a switch door is provided on the side of the protective box.

[0023] By providing the switch door, it is convenient for the staff to repair the inside of the protective box.

[0024] Furthermore, the axes of the housing and the circular saw coincide.

[0025] Furthermore, the rust prevention device includes an oil storage tank, 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. A cover is provided on the top of the oil storage tank.

[0036] When the right support plate moves downward to drive the support rod to move downward, the support rod moves downward to drive the first magnet to move downward, the first magnet moves downward to drive the second magnet to move downward, the second magnet moves downward to drive the sliding plate to move downward, and the sliding plate moves downward so that the antirust oil in the storage tank enters the transfer box through the inlet pipe, preparing for subsequent antirust operation on the circular saw.

[0037] When the sliding plate moves downward and contacts the limit plate, at this time, the first magnet still moves downward, and the first magnet moves downward and separates from the second magnet to prevent the sliding plate from detaching from the transfer box, resulting in leakage of antirust oil.

[0038] When the right support plate moves upward to drive the support rod to move upward, the support rod moves upward to drive the first magnet to move upward. When the circular saw separates from the surface of the mine raw stone, at this time, the first magnet contacts the second magnet. Subsequently, the first magnet moves upward to drive the second magnet to move upward, the second magnet moves upward to drive the sliding plate to move upward, and the sliding plate moves upward so that the antirust oil in the transfer box sequentially passes through the outlet pipe, the oil outlet tank, and finally sprays onto the circular saw through the filter screens in the two nozzles, forming a protective film on the cutting part of the circular saw to isolate air, moisture, and corrosive substances in the stone, reducing the occurrence of oxidation and corrosion, and extending the service life of the circular saw.

[0039] Furthermore, filter screens are respectively fixedly connected to the oil inlets of the two nozzles.

[0040] By setting the filter screens, dust is prevented from entering the oil outlet tank.

[0041] Furthermore, a push handle is fixedly connected to the side surface of the protective box.

[0042] By setting the push handle, it is convenient for the staff to push the protective box.

[0043] Furthermore, the protection device includes a protection cylinder, an oil outlet, a moving plate, a screw rod, an annular rack, and a gear. The axis of the protective cylinder is vertically arranged and coincides with the axis of the oil outlet tank. Both ends of the protective cylinder are open. The protective cylinder is sleeved outside the oil outlet tank and is rotatably connected to the inner bottom surface of the protective box, and its rotation axis is vertically arranged.

[0044] The oil outlet is arc-shaped. The oil outlet is arranged on the side of the protective cylinder and is located on the side of the oil outlet tank away from the storage tank. One end of the oil outlet is communicated with the inside of the protective box, and the other end is communicated with the inside of the protective cylinder. The width of the oil outlet is matched with the two nozzles.

[0045] The moving plate is arranged on the side of the protective cylinder away from the storage tank. The moving plate is horizontally arranged behind the support plate, is fixedly connected to the side surface of the support plate, and is slidably connected to the inner side surface of the protective box, and its sliding direction is vertically arranged.

[0046] The screw rod is vertically arranged on the side of the protective cylinder away from the storage tank. The upper end of the screw rod is rotatably connected to the inner top surface of the protective box, and its rotation axis is vertically arranged. The lower end penetrates downward through the moving plate and is rotatably connected to the inner bottom surface of the protective box, and its rotation axis is vertically arranged.

[0049] When the outer shell moves downward to drive the left support plate to move downward, the left support plate moves downward to drive the moving plate to move downward. The moving plate moves downward to drive the screw rod to rotate. The screw rod rotates to drive the gear to rotate. The gear rotates to drive the annular rack to rotate. The annular rack rotates to drive the protective cylinder to rotate. The protective cylinder rotates to drive the oil outlet to rotate. When the circular saw contacts the ground, at this time, the oil outlet is far away from the two nozzles, thereby preventing the situation that when the circular saw cuts the mine raw stone, some crushed stones will impact the two nozzles and cause damage to the two nozzles.

[0050] When the outer shell moves upward to drive the left support plate to move upward, the left support plate moves upward to drive the moving plate to move upward. The moving plate moves upward to drive the screw rod to rotate. The screw rod rotates to drive the gear to rotate. The gear rotates to drive the annular rack to rotate. The annular rack rotates to drive the protective cylinder to rotate. The protective cylinder rotates to drive the oil outlet to rotate. When the circular saw separates from the surface of the mine raw stone, at this time, the oil outlet is in front of the two nozzles, and the two nozzles start to spray anti-rust oil on the cutting part of the circular saw. Until the spraying operation ends, the oil outlet is always in front of the two nozzles, thereby avoiding wasting the anti-rust oil by spraying it on the inner wall of the protective cylinder.

[0074] When it is necessary to perform cutting operations on the mine raw stones, the staff push the protective box 1 and move the protective box 1 to the position of the ore to be mined. Subsequently, the staff turn on the four first cylinders 2 through the controller. The contraction of the first cylinders 2 drives the protective box 1 to move downward until the protective box 1 moves downward to the specified height, preparing for the subsequent cutting operations on the mine raw stones.

[0102] The axis of the gear 605 is vertically arranged and coincides with the axis of the screw rod 603. The gear 605 is sleeved outside the screw rod 603 and is on the side of the annular rack 604. The gear 605 is fixedly connected to the side surface of the screw rod 603 and meshes with the annular rack 604.

[0103] When the outer shell 402 moves downward to drive the left support plate 401 to move downward, the left support plate 401 moves downward to drive the moving plate 602 to move downward. The moving plate 602 moves downward to drive the screw rod 603 to rotate. The screw rod 603 rotates to drive the gear 605 to rotate. The gear 605 rotates to drive the annular rack 604 to rotate. The annular rack 604 rotates to drive the protective cylinder 601 to rotate. The protective cylinder 601 rotates to drive the oil outlet to rotate. When the circular saw 404 contacts the ground, at this time the oil outlet is far away from the two nozzles 511, thereby preventing the situation that when the circular saw 404 cuts the mine raw stone, some crushed stones will impact the two nozzles 511 and cause damage to the two nozzles 511.

[0104] When the outer shell 402 moves upward to drive the left support plate 401 to move upward, the upward movement of the left support plate 401 drives the moving plate 602 to move upward. The upward movement of the moving plate 602 drives the screw 603 to rotate. The rotation of the screw 603 drives the gear 605 to rotate. The rotation of the gear 605 drives the annular rack 604 to rotate. The rotation of the annular rack 604 drives the protective cylinder 601 to rotate. The rotation of the protective cylinder 601 drives the oil outlet to rotate. When the disk saw 404 is separated from the surface of the mine raw stone, at this time, the oil outlet is in front of the two nozzles 511, and the two nozzles 511 start to spray anti-rust oil on the cutting part of the disk saw 404 until the spraying operation ends. The oil outlet is always in front of the two nozzles 511, thus preventing the anti-rust oil from being sprayed on the inner wall of the protective cylinder 601 and causing waste.

[0105] A toolbox is fixedly connected to the inner bottom surface of the protective box 1.

[0106] By providing the toolbox, it is convenient for the staff to carry out maintenance operations.

[0107] The disk saw 404 is made of cemented carbide.

[0108] Cemented carbide has good hardness, heat resistance and wear resistance.

[0109] Working principle: When it is necessary to cut the mine raw stone, the staff push the protective box 1 through the push handle and push the protective box 1 to the position of the ore to be mined. Subsequently, the staff turn on the four first cylinders 2 through the controller. The contraction of the first cylinders 2 drives the protective box 1 to move downward until the protective box 1 moves downward to the specified height to prepare for the subsequent cutting operation of the mine raw stone; Subsequently, the staff turn on the second cylinder 406 through the controller. The contraction of the second cylinder 406 drives the right support plate 401 to move downward. The downward movement of the right support plate 401 drives the outer shell 402 and the support rod 505 to move downward in sequence; When the downward movement of the right support plate 401 drives the support rod 505 to move downward, the downward movement of the support rod 505 drives the first magnet 506 to move downward. The downward movement of the first magnet 506 drives the second magnet 507 to move downward. The downward movement of the second magnet 507 drives the sliding plate 503 to move downward. The downward movement of the sliding plate 503 enables the anti-rust oil in the oil storage tank 501 to enter the transfer box 502 through the oil inlet pipe 508 to prepare for the subsequent anti-rust operation of the disk saw 404; When the sliding plate 503 moves downward and contacts the limit plate 504, at this time, the first magnet 506 still moves downward, and the first magnet 506 moves downward and separates from the second magnet 507 to prevent the sliding plate 503 from detaching from the transfer box 502 and causing anti-rust oil leakage; When the right support plate 401 moves downward to drive the housing 402 to move downward, the housing 402 moves downward to drive the left support plate 401 and the two rotating rods 403 to move downward in sequence; When the housing 402 moves downward to drive the two rotating rods 403 to move downward, the two rotating rods 403 move downward to drive the circular saw 404 to move downward until the circular saw 404 contacts the surface of the mine raw stone. At this time, the staff turns on the motor 405 through the controller. The motor 405 rotates to drive the right rotating rod 403 to rotate, and the right rotating rod 403 rotates to drive the circular saw 404 to rotate. At this time, the circular saw 404 moves downward, so as to perform cutting operations on the mine raw stone; When the housing 402 moves downward to drive the left support plate 401 to move downward, the left support plate 401 moves downward to drive the moving plate 602 to move downward. The moving plate 602 moves downward to drive the screw rod 603 to rotate. The screw rod 603 rotates to drive the gear 605 to rotate. The gear 605 rotates to drive the annular rack 604 to rotate. The annular rack 604 rotates to drive the protective cylinder 601 to rotate. The protective cylinder 601 rotates to drive the oil outlet to rotate. When the circular saw 404 contacts the ground, at this time, the oil outlet is far away from the two nozzles 511, so as to prevent the situation that when the circular saw 404 performs cutting operations on the mine raw stone, some crushed stones will impact the two nozzles 511, resulting in damage to the two nozzles 511; After the cutting operation is completed, the staff turns on the second cylinder 406 through the controller. The second cylinder 406 extends to drive the right support plate 401 to move upward. The right support plate 401 moves upward to drive the housing 402 and the support rod 505 to move upward in sequence; When the right support plate 401 moves upward to drive the support rod 505 to move upward, the support rod 505 moves upward to drive the first magnet 506 to move upward. When the circular saw 404 is separated from the surface of the mine raw stone, at this time, the first magnet 506 contacts the second magnet 507. Subsequently, the first magnet 506 moves upward to drive the second magnet 507 to move upward. The second magnet 507 moves upward to drive the sliding plate 503 to move upward. The upward movement of the sliding plate 503 causes the anti-rust oil in the transfer box 502 to pass through the oil outlet pipe 510 and the oil tank 509 in sequence, and finally spray onto the circular saw 404 through the filter screens in the two nozzles 511, forming a protective film on the cutting part of the circular saw 404 to isolate air, moisture and corrosive substances in the stone, reduce oxidation and corrosion, and extend the service life of the circular saw 404; When the right support plate 401 moves upward to drive the housing 402 to move upward, the housing 402 moves upward to drive the left support plate 401 and the two rotating rods 403 to move upward in sequence; When the outer shell 402 moves upward to drive the two rotating rods 403 to move upward, the two rotating rods 403 move upward to drive the circular saw 404 to move upward until the circular saw 404 is separated from the surface of the mine raw stone. At this time, the staff turns on the motor 405 through the controller, so that the rotating shaft of the motor 405 rotates slowly. The slow rotation of the rotating shaft of the motor 405 drives the right rotating rod 403 to rotate slowly, and the slow rotation of the right rotating rod 403 drives the circular saw 404 to rotate slowly, so as to ensure that the antirust oil can be evenly sprayed on the cutting part of the circular saw 404; When the outer shell 402 moves upward to drive the left support plate 401 to move upward, the left support plate 401 moves upward to drive the moving plate 602 to move upward. The upward movement of the moving plate 602 drives the screw rod 603 to rotate. The rotation of the screw rod 603 drives the gear 605 to rotate. The rotation of the gear 605 drives the annular rack 604 to rotate. The rotation of the annular rack 604 drives the protective cylinder 601 to rotate. The rotation of the protective cylinder 601 drives the oil outlet to rotate. When the circular saw 404 is separated from the surface of the mine raw stone, at this time, the oil outlet is in front of the two nozzles 511, and the two nozzles 511 start to spray antirust oil on 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 preventing the antirust oil from being sprayed on the inner wall of the protective cylinder 601 and causing waste.

[0110] When a failure occurs in the transmission parts in the protection box 1, the staff can timely open the switch door of the protection box 1 and take out the maintenance tools from the toolbox to repair it.

[0111] The above embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present invention.
