Description

Technical Field

[0001] This utility model relates to the field of ore mining technology, and in particular to a piercing device for iron ore mining. Background Technology

[0002] A search revealed Chinese patent CN217925757U, which discloses an iron ore mining piercing device. The device includes a support plate and a drive motor. A supporting and guiding mechanism is located on the upper right side of the support plate. A piercing rod passes through the interior of this mechanism and is sleeved on the right side of a movable block via bearings. Guide rods are installed at both ends of the bottom of the movable block, and a push rod is located on the side of the movable block opposite to the piercing rod. During the rotation of the drive motor-controlled adjustment mechanism, the piercing rod can be pushed by the push rod to reciprocate left and right under the guidance of the guide rods. Because the outer wall of the piercing rod has a spiral guide groove, it rotates under the pressure of the spherical protrusions during the left-right sliding process, reducing the resistance during iron ore piercing and solving the problems of high resistance, low efficiency, and severe wear during piercing.

[0003] The iron ore mining piercing device in the aforementioned patent has a spiral guide groove on the outer wall of the piercing rod. Therefore, during the left and right sliding of the piercing rod, the piercing rod will rotate under the squeezing action of the spherical protrusion, which can reduce the resistance when piercing iron ore and solve the problems of high resistance, low piercing efficiency and severe wear during piercing. However, a large amount of gravel will be generated during the ore mining process. Since the guide groove is opened on the surface of the piercing rod, the gravel can easily enter the guide groove, which will easily cause excessive friction between the guide groove and the spherical protrusion. As a result, over time, the guide groove cannot fit tightly with the spherical protrusion. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a drilling device for iron ore mining.

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

[0006] A piercing device for iron ore mining includes an operating platform. Two limiting rods are symmetrically fixedly connected to the top of the operating platform. The same push plate is sleeved on the surface of the two limiting rods. A piercing rod is rotatably connected to one side of the push plate. A second worm gear is sleeved on the surface of the piercing rod near the push plate. The surface of the second worm gear is provided with a rotating mechanism for rotating the piercing rod. A motor is fixedly connected to the top of the operating platform on the side away from the piercing rod. An adjusting disc is fixedly connected to the output shaft of the motor. The surface of the adjusting disc is provided with a moving mechanism for moving the push plate. The second worm gear allows the piercing rod to rotate more stably.

[0007] As a further embodiment of this utility model, the rotating mechanism includes a second worm gear, which is rotatably connected to one side of the push plate. The push plate and the second worm wheel are configured to cooperate with each other. A gear is sleeved at the bottom of the second worm gear, and a rack is fitted on the surface of the gear. The rack is fixedly connected to the bottom of the operating table. A baffle is fixedly connected to the surface of the push plate near the rack. The rack allows the chisel rod to rotate.

[0008] As a further embodiment of this utility model, the moving mechanism includes a slider, which is disposed on one side of the adjusting plate and is offset from the center. A sliding column is fixedly connected to the surface of the slider away from the adjusting plate, and an adjusting rod is rotatably connected to the surface of the sliding column. The other end of the adjusting rod is rotatably connected to one side of the push plate. An adjusting mechanism for adjusting the sliding column is provided on one side of the adjusting plate. The adjusting rod allows the chisel rod to move.

[0009] As a further embodiment of this utility model, the adjusting mechanism includes a lead screw, which is rotatably connected to one side of the adjusting disk. A slider is sleeved on the surface of the lead screw, and the slider and the lead screw are configured to cooperate with each other. A first worm gear is sleeved on the end of the lead screw away from the chisel rod, and a first worm is fitted on the surface of the first worm gear. The first worm is rotatably connected to one side of the adjusting disk. Four connecting feet are fixedly connected to the bottom of the operating table. The four connecting feet are evenly arranged in a square shape. The slide column can be moved by the lead screw.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model employs a technical solution where a second worm gear drives the chisel rod to rotate, enabling the chisel rod to rotate more stably. This effectively solves the problem that because the guide groove is located on the surface of the chisel rod, gravel easily enters the guide groove, leading to excessive friction between the guide groove and the spherical protrusion. Consequently, over time, the guide groove cannot achieve a tight fit with the spherical protrusion. A second worm gear is installed at one end of the chisel rod, and a second worm is fitted onto its surface. A gear is installed at the bottom of the second worm. A rack is installed on the bottom of the operating table near the gear, and the rack meshes with the gear. Thus, when the adjusting rod moves the chisel rod, the rack ensures that the chisel rod rotates synchronously, guaranteeing more stable operation of the chisel rod. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Reference Figures 1-4A piercing device for iron ore mining includes an operating platform 1. Two limiting rods 301 are symmetrically fixedly connected to the top of the operating platform 1. The same push plate 302 is sleeved on the surface of the two limiting rods 301. A piercing rod 3 is rotatably connected to one side of the push plate 302. A second worm gear 303 is sleeved on the surface of the piercing rod 3 near the push plate 302. The surface of the second worm gear 303 is provided with a rotating mechanism for rotating the piercing rod 3.

The surface of the adjusting plate 2 is provided with a moving mechanism for moving the push plate 302. The setting of the second worm gear 303 can make the piercing rod 3 rotate more stably.

[0020] Preferably, the rotating mechanism includes a second worm gear 304, which is rotatably connected to one side of the push plate 302. The push plate 302 and the second worm wheel 303 are configured to cooperate with each other. A gear 305 is sleeved at the bottom of the second worm gear 304, and a rack 306 is fitted on the surface of the gear 305. The rack 306 is fixedly connected to the bottom of the operating table 1. A baffle 307 is fixedly connected to the surface of the push plate 302 near the rack 306. The rack 306 allows the chisel rod 3 to rotate.

[0021] Furthermore, the moving mechanism includes a slider 205, which is disposed on one side of the adjusting plate 2 and is offset from the center. A sliding column 206 is fixedly connected to the surface of the slider 205 away from the adjusting plate 2. An adjusting rod 207 is rotatably connected to the surface of the sliding column 206. The adjusting rod 207 can be moved by the sliding column 206. The other end of the adjusting rod 207 is rotatably connected to one side of the push plate 302. An adjusting mechanism for adjusting the sliding column 206 is provided on one side of the adjusting plate 2. The chisel rod 3 can be moved by the adjusting rod 207.

[0022] Furthermore, the adjustment mechanism includes a lead screw 202, which is rotatably connected to one side of the adjustment disk 2. A slider 205 is sleeved on the surface of the lead screw 202, and the slider 205 and the lead screw 202 are configured to cooperate with each other. A first worm gear 203 is sleeved on the end of the lead screw 202 away from the chisel rod 3. A first worm 204 is fitted on the surface of the first worm gear 203. The first worm 204 can lock the lead screw 202 to prevent the lead screw 202 from rotating during the operation of the chisel rod 3.
