[0002] A geological drilling machine is a mechanical device used to drill underground rock or soil. It is usually composed of an electric motor, a hydraulic pump and a rotating head. Its function is to use the high-speed rotation of the drill bit to break the rock into small pieces and take out samples for analysis or collection.

[0003] At present, the purpose of engineering geology is to identify the geological conditions of various engineering sites, conduct a comprehensive evaluation of the sites and various related geological problems, analyze and predict the possible changes and effects of geological conditions under the action of engineering construction, select the best site, and propose engineering measures to solve adverse geological problems, so as to provide a reliable scientific basis for ensuring the reasonable design, smooth construction and normal use of the project. In the process of engineering geological exploration, drilling is the most common step;

[0004] However, in existing engineering geological exploration processes, drills can often only drill straight up and down and cannot drill from other angles. Therefore, they are less practical and cannot adapt to different drilling needs. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a multi-angle drilling device for engineering geological exploration.

[0006] The technical solution adopted to solve the above technical problems is: a multi-angle drilling device for engineering geological exploration, including a workbench, a circular hole is opened in the middle of the interior of the workbench, a rotating mechanism is provided in the middle of the upper part of the workbench, and the rotating mechanism can drive the internal structure to rotate, a side panel is provided above the outside of the workbench, a drilling mechanism is provided in the middle of the inner part of the side panel, and the drilling mechanism can perform drilling work, angle adjustment mechanisms are provided on both sides of the outer side of the side panel, and the angle adjustment mechanism can adjust the drilling angle of the drilling mechanism, a lifting mechanism is provided above the inner part of the side panel, and the lifting mechanism can adjust the height position of the drilling mechanism, and auxiliary adjustment mechanisms are provided at the four corners of the lower outside of the workbench, and the auxiliary adjustment mechanism can assist the angle adjustment mechanism in performing precise angle adjustment.

[0007] Through the above technical solution, when drilling work is to be carried out, the device is first placed in a suitable working position and then the drilling mechanism is started to drill. Before drilling work, the angle adjustment mechanism and the auxiliary adjustment mechanism can be used to adjust the inclination angle of the drilling mechanism, thereby realizing drilling at different angles, and the rotating mechanism drives the drilling mechanism to rotate, thereby realizing drilling in different directions. With the cooperation of the two, the drilling mechanism can realize drilling at positions of different angles and directions, thereby improving the practicality of the device, and the setting of the lifting mechanism can drive the drilling mechanism to move up and down.

[0035] like Figure 1 - Figure 5As shown, the rotating mechanism 300 includes a fixed frame 304 fixedly connected to the top of the workbench 200. The fixed frame 304 is circular and has a notch inside. A driven gear 303 is provided between the fixed frame 304 and the workbench 200. A transverse groove 308 is provided in the middle of the driven gear 303 so that the drill bit 401, the transmission shaft 402 and the drilling motor 403 can move inside the transverse groove 308 without colliding with other structures. The upper surface of the driven gear 303 is fixedly connected to the side plate 101. The side plate 101 is located at the transverse groove 308. On both sides of the groove 308, the driven gear 303 is located above the circular hole 201, and a clamping block 305 is provided inside the fixed frame 304. The clamping block 305 is located at the notch opened inside the fixed frame 304. The guide rod 310 is fixedly connected to both sides of the upper outside of the fixed frame 304. The clamping block 305 is located outside the guide rod 310. A handle 309 is fixedly connected to the upper outside of the clamping block 305.

[0036] The rotating mechanism 300 also includes a fixed rod 301 fixedly set above the workbench 200, and a connecting frame 302 is placed on the outside of the fixed rod 301.

The lifting rod 110 is located inside the slide groove 107. In this way, when the drilling mechanism 400 is drilling, the lifting rod 110 cooperates with the slide groove 107 to prevent the drilling mechanism 400 from deviating. A lifting motor 105 is fixedly connected to the middle of the upper part of the side plate 101, and a lifting gear 108 is fixedly connected to the output end of the lifting motor 105. They do not contact each other, so that the lifting gear 108 and the lifting motor 105 on one side will not collide or interfere with the lifting gear 108 and the lifting motor 105 on the other side. The lifting gears 108 do not contact each other. Rod holes 109 are opened on both sides of the upper part of the side plate 101, and rotating rods 111 are provided inside the rod holes 109. The outside of the rotating rod 111 is fixedly connected to the active plate 104, and the middle part of the outside of the rotating rod 111 is fixedly connected to the connecting gear 106, and the connecting gear 106 is meshed with the lifting gear 108.

[0039] The lifting mechanism 100 also includes a driven plate 103 connected to the active plate 104. The driven plate 103 rotates around the active plate 104. The driven plate 103 is placed on the outside of the fixed shaft 405 at the end away from the active plate 104. The active plate 104 is fixedly connected to the pressure plate 102 on the upper surface of the end away from the rotating rod 111, and a plate groove is opened on the lower surface of the outside of the active plate 104.

[0040] The angle adjustment mechanism 600 includes sliders 602 fixed on both sides of the outside of the lifting rod 110, a slot 604 is opened inside the slider 602, the slot 604 passes through the slider 602, the slot 604 is arranged in a circle inside the slider 602, an insertion rod 601 is arranged inside the slot 604, and a guide plate 603 is fixedly provided on the surface of the side away from each other of the side plate 101. The insertion rod 601 is located inside the guide plate 603, and the guide plate 603 is located on both sides of the side plate 101. The insertion rod 601 is located inside the guide plate 603. The insertion rod 601 moves along the guide rod 310. A nut 605 is rotatably placed on one end of the outside of the insertion rod 601, and the insertion rod 601 is arranged inside the guide rod 310 through the nut 605.

[0041] like Figure 10As shown, the auxiliary adjustment mechanism 500 includes a fixed ring 504 fixedly connected to the workbench 200, and the fixed ring 504 is located at the four corners of the outer lower surface of the workbench 200. A screw 502 is provided inside the fixed ring 504, and the screw 502 rotates inside the fixed ring 504. A swivel 503 is placed on the outside of the screw 502, and a support leg 501 is placed on the outside of the screw 502. The swivel 503 is located between the support leg 501 and the fixed ring 504. A receiving groove 505 is opened inside the support leg 501, and the inner wall of the receiving groove 505 is engraved with a thread, so that the screw 502 can be rotated and stored into the receiving groove 505, and the screw 502 is located inside the receiving groove 505.

[0042] The working principle of this embodiment is as follows. When using this device for drilling work, first place this device above a suitable position, then adjust the angle adjustment mechanism 600 according to the drilling angle requirements on site, first turn the drill bit 401, the transmission shaft 402 and the drilling motor 403 to rotate, and when the drill bit 401, the transmission shaft 402 and the drilling motor 403 and other structures are rotated to the approximate drilling angle, the insertion rod 601 can be inserted into the slot 604, and then the nut 605 is rotated to close one end of the insertion rod 601 until the two ends of the insertion rod 601 are in contact with the surface of the guide plate 603, so that the insertion rod 601 will not easily tilt or change its angle when moving up and down;

[0043] Then the rotating mechanism 300 can be started. First, the handle 309 is pulled to drive the block 305 to move in the direction away from the fixed frame 304. The handle 309 will compress the spring 311, and the block 305 will move to the top of the fixed frame 304. Then the connecting frame 302 is toggled around the fixing rod 301 to rotate in the direction of the fixed frame 304 until the driving gear 307 is rotated to the notch of the fixed frame 304 and meshes with the driven gear 303. At this time, the rotating wheel 306 can be rotated to drive the driving gear 307 to rotate, and the driven gear 303 meshed with it will also be driven to rotate. At the same time, the lifting mechanism 100, the drilling mechanism 400 and the angle adjustment mechanism 600 above the driven gear 303 will also be driven to rotate together until the drill bit 401 faces the direction where the hole needs to be drilled, and the rotation can be stopped.

[0044] When the drill bit 401 is rotated to the drilling direction, the connecting frame 302 is toggled to drive the driving gear 307 and the rotating wheel 306 away from the fixed frame 304. At the same time, the handle 309 is released. Under the self-resetting function of the spring 311, the clamping block 305 is rebounded and lowered, and the locking teeth 312 provided on the surface of the clamping block 305 are engaged with the tooth grooves of the driven gear 303. In this way, the driven gear 303, the lifting mechanism 100, the drilling mechanism 400 and the angle adjustment mechanism 600 are fixed so that they cannot easily rotate on their own.

[0045] When the drill bit 401 is tilted to a rough angle, it can be fine-tuned according to the auxiliary adjustment mechanism 500. Because the auxiliary adjustment mechanisms 500 are provided at the four corners of the workbench 200, one or more auxiliary adjustment mechanisms 500 can be adjusted according to actual usage. When adjusting the auxiliary adjustment mechanism 500, first rotate the rotating ring 503 to make it rotate outside the screw rod 502. Because the screw rod 502 is restricted inside the fixed ring 504, the screw rod 502 cannot be lifted or lowered. However, the screw rod 502 rotates inside the receiving groove 505 opened inside the support leg 501 during the rotation process. Because the receiving groove 505 has a thread inside, the screw rod 502 will extend or shrink the distance between it and the support leg 501 when it rotates, so that one corner of the workbench 200 will be raised or lowered, thereby achieving the effect of assisting in adjusting the inclination angle of the drill bit 401.

[0046] When drilling, first start the drilling motor 403 to drive the drill bit 401 to rotate through the transmission shaft 402, and because of gravity, the drill bit 401 will naturally fall above the drilling position, and then start the lifting motor 105 to run, the lifting motor 105 drives the lifting gear 108 to rotate, and the connecting gear 106 meshing with it will also be driven to rotate. Because the connecting gear 106 is fixedly connected to the active plate 104, the active plate 104 will also rotate when the connecting gear 106 rotates, and the active plate 104 will rotate when the drilling motor When the driving plate 104 rotates in the direction of the drilling motor 403, it will have the effect of lowering the drill bit 401. When the active plate 104 rotates in the direction of the drilling motor 403, it will press the driven plate 103 through the pressure plate 102 fixed on its outside. The driven plate 103 and the active plate 104 will gradually form a straight line and press the drilling motor 403 and the drill bit 401 downward, so that the drilling work will be carried out. When the drilling motor 403 rotates, it will move along the slide groove 107 through the lifting rod 110, so as to ensure that the drill bit 401 will not easily deviate when drilling.

[0047] In this way, with the cooperation of the angle adjustment mechanism 600 and the auxiliary adjustment mechanism 500, the drill bit 401 can adjust the inclination angle, and the setting of the rotation mechanism 300 can adjust the direction of the drill bit 401 360 degrees. With the cooperation of the two, the device can realize drilling at any angle and in any direction, thereby improving the applicability of the present invention.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
