[0037] Figure 1 Figure 7 The structure of the drilling equipment for mine geological exploration of the present application is shown, please refer to Figure 1 Figure 7 The drilling equipment for mine geological exploration is described in detail.

[0038] Example 1

[0039] Reference Figures 1-7 The present application discloses a drilling equipment for mine geological exploration, which comprises a vibration drilling mechanism 100, an ore conveying mechanism 200 and a hole wall protection mechanism 300.

[0040] Reference Figures 1-4 The vibration drilling mechanism 100 is used for drilling by high-frequency vibration when working, and is located at the front end of the equipment and drills by high-frequency vibration when working, so as to minimize the damage to the core ore and the hole wall. The vibration drilling mechanism 100 comprises a protection shell 110, a drill rod 120 and a vibration generating assembly 130 installed in the protection shell 110 and driving the drill rod 120 to vibrate at high frequency when working. The protection shell 110 is used for installing the vibration generating assembly and sealing and protecting the vibration generating assembly 130. The drill rod 120 is used for drilling the mine rock when subjected to high-frequency vibration. The vibration generating assembly 130 is used for generating high-frequency vibration when working, so as to drive the drill rod 120 to drill at high frequency. Reference Figure 4The vibration generating assembly 130 comprises a bottom plate 131 located in the protective shell 110, a connecting frame 132 mounted on the bottom plate 131, an eccentric assembly 133 movably mounted on the connecting frame 132, and a driving motor 134 mounted on the top of the bottom plate 131 and having an output end in transmission connection with the eccentric assembly 133. The bottom plate 131 is used for mounting the connecting frame 132, the connecting frame 132 is used for movably mounting the eccentric assembly 133, the eccentric assembly 133 is used for generating high-frequency vibration when rotating, and the driving motor 134 is used for driving the eccentric assembly 133 to rotate when working.

[0041] With reference to Figures 1-5 The ore conveying mechanism 200 is used for sequentially collecting part of the core ore generated in the working process of the vibration drilling mechanism 100. The ore conveying mechanism 200 is mounted on the top of the vibration drilling mechanism 100. When the vibration drilling mechanism 100 works, the ore conveying mechanism 200 is automatically driven to work, and part of the core ore generated in the working process of the vibration drilling mechanism 100 is collected. Thus, in the process of drilling by the vibration drilling mechanism, the ore conveying mechanism 200 is automatically driven to work, and the core ore in the hole is sequentially collected, thereby facilitating the analysis of the core ore in the exploration process.

[0042] With reference to Figures 1-7 The hole wall protection mechanism 300 is used for reinforcing the fragile part of the inner wall of the drilled hole when working, thereby avoiding the collapse of the geologically weak part. The hole wall protection mechanism 300 is mounted on the top of the ore conveying mechanism 200. When the ore conveying mechanism 200 works, after the collection of the core ore is completed, the hole wall protection mechanism 300 is automatically driven to work, and the geologically weak part of the inner wall of the drilled hole is reinforced and protected. The hole wall protection mechanism 300 comprises a second shell 310, a cementing agent storage tube 320 located in the second shell 310, and a triggering assembly 330 having one end in transmission connection with the cementing agent storage tube 320 and the other end in transmission connection with the ore conveying mechanism 200. The second shell 310 is used for mounting the cementing agent storage tube 320 and the triggering assembly 330. The cementing agent storage tube 320 is used for storing the cementing agent. The triggering assembly 330 is used for automatically triggering the cementing agent storage tube 320 to spray cement into the hole when the core ore in the ore conveying mechanism 200 is collected and the hole moves to the fragile part of the hole wall, thereby reinforcing and protecting the relatively fragile part of the hole wall and avoiding the collapse of the hole.

[0043] In the embodiment, the following process is used: when the mine is explored by drilling, the vibration drilling mechanism 100 is first operated to drill by high-frequency vibration, and at the same time, the ore conveying mechanism 200 automatically collects part of the core ore in the drilling process; when the core ore is collected, the hole wall protection mechanism 300 is automatically triggered to work; in the continuous drilling process, the inner wall of the hole is reinforced, and the hole is prevented from collapsing.

[0046] The output end of the driving motor 134 is connected with a belt pulley set 1341, the other end of which is in transmission connection with the first rotating rod 1331, for driving the first rotating rod 1331 to rotate when the driving motor 134 works.

[0047] In the embodiment, referring to Figure 4 The vibration generating assembly 130 further includes a correction assembly 135 for increasing the overall eccentric centrifugal force, so that the high-frequency vibration is more stable and powerful; the correction assembly 135 includes a second rotating rod 1351 movably mounted on the other connecting frame 132 and a second eccentric wheel 1352 located on the second rotating rod 1351.

[0050] In addition, the correction assembly 135 and the first eccentric assembly 133 are symmetrically distributed on the bottom plate 131, and the rotation not only makes the vibration more powerful, but also offsets the lateral tension when the first eccentric wheel 1332 rotates, so that the vibration generating assembly 130 is prevented from vibrating left and right and up and down under the action of lateral centrifugal force when the first eccentric wheel 1332 rotates, and the vibration generating assembly only performs up and down displacement vibration, so that the vibration correction operation is completed.
