Description

Technical Field

[0001] This utility model specifically relates to a drilling machine for mining operations, belonging to the field of drilling technology for mining operations. Background Technology

[0002] Hydraulic rock drills use high-pressure oil as their working power and are characterized by low energy consumption, small size, light weight, high impact energy, fast drilling speed, low noise, and low vibration. They can be used for geological exploration, tunnel excavation, drilling blast holes in quarrying, hydropower, railway and other projects, and can also be used for controlled blasting in urban demolition of old buildings.

[0003] According to application number 202420314672.9, a mining drilling machine is disclosed, comprising a support frame with rollers at its bottom. A rotating shaft is rotatably connected to the support frame via bearings. A connecting block is fixedly connected to the rotating shaft, and a first hydraulic cylinder is fixedly connected to the connecting block. A motor is fixedly connected to the first hydraulic cylinder, and a drill bit is fixedly connected to the motor. Gears are fixedly connected to both ends of the rotating shaft, and racks mesh with both gears. The two racks move via a moving mechanism. This invention allows for drilling at different angles without requiring manual support, thus improving operational convenience.

[0004] The above solution still has certain shortcomings in actual use. There is a key technical oversight in the above solution: the drill bit will generate an upward holding force during drilling, but the above solution does not set a buffer mechanism for the first hydraulic rod. If it is under this working condition for a long time, the hydraulic rod will continuously bear the impact force without buffering, which is very likely to cause cylinder failure, directly causing the entire device to lose its working ability and seriously affecting the service life of the equipment. Summary of the Invention

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a mining drilling machine, including a mounting plate. A push handle is fixedly connected to the upper surface of the mounting plate, a control panel is mounted on the outer surface of the mounting plate, and two handles are fixedly connected to the outer surface of the mounting plate. A drilling shock absorption assembly is mounted on the bottom surface of the mounting plate, and the drilling shock absorption assembly includes a short shaft. The short shaft is mounted on the bottom surface of the mounting plate, and a connecting frame is fixedly connected to the bottom end of the short shaft. A connecting shaft is rotatably connected inside the connecting frame, and a first bevel gear is fixedly connected to one end of the connecting shaft.

[0006] Furthermore, the drilling shock absorption assembly also includes a brake motor mounted on the outer surface of the mounting plate, the output end of which is fixedly connected to a second bevel gear, and the second bevel gear meshes with the first bevel gear.

[0007] Furthermore, a connecting plate is fixedly connected to the outer surface of the connecting shaft, and a hydraulic rod is fixedly connected to the bottom surface of the connecting plate.

[0008] Furthermore, a horizontal plate is fixedly connected to the output end of the hydraulic rod, a shock-absorbing plate is provided below the horizontal plate, and a set of dampers and springs are provided between the horizontal plate and the shock-absorbing plate.

[0009] Furthermore, a slide cylinder is fixedly connected to the upper surface of the damping plate, a slide rod is slidably connected to the upper surface of the slide cylinder, a circular plate is fixedly connected to the bottom end of the slide rod, and a rubber ring is fitted on the outer surface of the circular plate, with the rubber ring in contact with the inner wall of the slide cylinder.

[0010] Furthermore, a servo motor is fixedly connected to the bottom surface of the shock-absorbing plate, and a drill bit is fixedly connected to the output end of the servo motor. Beneficial effects

[0011] With the combined installation of the mounting plate and the drilling vibration damping component, the drilling vibration damping component can not only realize the drilling work in the mine, but also buffer the top force generated during drilling, so that the cylinder will not explode or the device will lose its working capacity, thus ensuring the service life of the equipment.

[0012] By using a combination of hydraulic rods, cross plates, damping plates, dampers, springs, slide cylinders, slide rods, circular plates, and rubber rings, the damping plate shakes. The springs and slide cylinders work together to dampen the vibration of the damping plate. The sliding connection between the slide cylinder and slide rod generates friction, which further weakens the shaking of the damping plate. This prevents the hydraulic rod from being subjected to pressure during subsequent drilling, thus preventing cylinder explosion. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 As shown, a mining drilling machine includes 1. A push handle 2 is fixedly connected to the upper surface of the mounting plate 1. The push handle 2 can provide certain convenience for moving the mounting plate 1, thereby facilitating subsequent drilling work.

[0020] The outer surface of the mounting plate 1 is equipped with a control panel 3, which can control the switching on and off of the entire device, thus facilitating subsequent operation and use by staff.

[0021] Two handles 4 are fixedly connected to the outer surface of the mounting plate 1, and the handles 4 provide a certain degree of support for the workers' hands.

[0022] A perforated vibration damping component 5 is installed on the bottom surface of the mounting plate 1. The perforated vibration damping component 5 includes a short shaft 501, which is installed on the bottom surface of the mounting plate 1. A connecting frame 502 is fixedly connected to the bottom end of the short shaft 501. A connecting shaft 503 is rotatably connected inside the connecting frame 502. Through the rotatable connection between the connecting frame 502 and the connecting shaft 503, the rotation of the connecting shaft 503 can be limited to a certain extent, thereby ensuring the subsequent use effect of the connecting shaft 503.

[0023] One end of the connecting shaft 503 is fixedly connected to a first bevel gear 504. The drilled shock absorption assembly 5 also includes a brake motor 505 mounted on the outer surface of the mounting plate 1. The output end of the brake motor 505 is fixedly connected to a second bevel gear 506, and the second bevel gear 506 meshes with the first bevel gear 504. Through the operation of the brake motor 505, and by utilizing the meshing between the second bevel gear 506 and the first bevel gear 504, the rotation of the connecting shaft 503 can be achieved.

[0024] A connecting plate 507 is fixedly connected to the outer surface of the connecting shaft 503. As the connecting shaft 503 rotates, the tilt angle of the connecting plate 507 can be adjusted, which facilitates subsequent drilling work.

[0025] A hydraulic rod 508 is fixedly connected to the bottom surface of the connecting plate 507. A horizontal plate 509 is fixedly connected to the output end of the hydraulic rod 508. The hydraulic rod 508 can adjust the position of the horizontal plate 509, thereby ensuring the subsequent use effect of the horizontal plate 509. A shock-absorbing plate 510 is set below the horizontal plate 509, and a set of dampers 511 and springs 512 are set between the horizontal plate 509 and the shock-absorbing plate 510. When the shock-absorbing plate 510 shakes, the dampers 511 and springs 512 work together to dampen the shaking force, thereby achieving a shock absorption effect and ensuring the normal use of the hydraulic rod 508.

[0026] A slide cylinder 513 is fixedly connected to the upper surface of the damping plate 510. A slide rod 514 is slidably connected to the upper surface of the slide cylinder 513. A circular plate 515 is fixedly connected to the bottom end of the slide rod 514. A rubber ring 516 is fitted on the outer surface of the circular plate 515, and the rubber ring 516 contacts the inner wall of the slide cylinder 513. When the damping plate 510 shakes, the slide rod 514 will retract into the interior of the slide cylinder 513. Then, the movement of the rubber ring 516 against the inner wall of the slide cylinder 513 will generate a certain amount of friction, thereby further reducing the shaking effect of the damping plate 510.

[0027] A servo motor 517 is fixedly connected to the bottom surface of the shock absorber 510. A drill bit 518 is fixedly connected to the output end of the servo motor 517. Through the operation of the servo motor 517, the drill bit 518 can be rotated, thereby enabling drilling work and ensuring normal use by the staff.

[0028] As a technical optimization of this utility model, when drilling in a mine, the device is first moved to a suitable position, then the brake motor 505 is started. The output of the brake motor 505 drives the second bevel gear 506 to rotate. The meshing between the second bevel gear 506 and the first bevel gear 504 allows for adjustment of the tilt angle of the connecting plate 507. Then, the hydraulic rod 508 is started to move the drill bit 518 to contact the mine surface. Finally, the servo motor 517 is started, and the output of the servo motor 517 drives the drill bit 518 to rotate, starting the drilling operation in the mine. When the damping plate 510 shakes, the cooperation between the spring 512 and the slide cylinder 513 can dampen the vibration of the damping plate 510. The sliding connection between the slide cylinder 513 and the slide rod 514 generates friction during the sliding process, further weakening the shaking of the damping plate 510. Therefore, no pressing pressure is applied to the hydraulic rod 508 during subsequent drilling, thus preventing cylinder explosion.
