[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 find out 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 unfavorable 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; However, in the existing engineering geological exploration process, the drill can usually only drill straight up and down, and cannot drill from other angles. Therefore, it is less practical and cannot adapt to different drilling needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a multi-angle drilling device for engineering geological exploration.

[0005] 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 part of the workbench, a rotating mechanism is arranged in the middle part above the workbench, and the rotating mechanism can drive the internal structure to rotate, a side panel is arranged above the outside of the workbench, a drilling mechanism is arranged in the middle part of the side panel, and the drilling mechanism can perform drilling work, angle adjustment mechanisms are arranged on both sides of the outside of the side panel, and the angle adjustment mechanism can adjust the drilling angle of the drilling mechanism, a lifting mechanism is arranged above the inside of the side panel, and the lifting mechanism can adjust the height position of the drilling mechanism, and auxiliary adjustment mechanisms are arranged at the four corners below the outside of the workbench, and the auxiliary adjustment mechanism can assist the angle adjustment mechanism in performing precise angle adjustment.

[0006] Through the above technical scheme, 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, so as to achieve drilling at different angles, and the rotating mechanism drives the drilling mechanism to rotate, so as to achieve drilling in different directions. Under the cooperation of the two, the drilling mechanism can achieve drilling at positions of different angles and directions, thereby improving the practicability of the device, and the setting of the lifting mechanism can drive the drilling mechanism to lift and move.

[0015] Through the above technical solution, when the active plate rotates, the pressure plate is used to press the driven plate to straighten and descend, so that the drilling mechanism can descend stably, and the opening of the plate groove will enable the driven plate to be well stored and folded into the active plate, so that the drilling mechanism can be lifted better.

[0031] like Fig.10As shown, the auxiliary adjustment mechanism 500 includes a fixing ring 504 fixedly connected to the workbench 200, the fixing ring 504 is located at the four corners of the outer lower surface of the workbench 200, a screw 502 is arranged inside the fixing ring 504, the screw 502 rotates inside the fixing ring 504, a swivel ring 503 is sleeved on the outside of the screw 502, a support leg 501 is sleeved on the outside of the screw 502, the swivel ring 503 is located between the support leg 501 and the fixing 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 threads, 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.

[0032] The working principle of this embodiment is as follows. When using this device for drilling work, first place this device above a suitable position, and 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 turned to a rough 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 and the angle will not change when moving up and down; Then the rotating mechanism 300 can be started, and the handle 309 is pulled first 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, and then the connecting frame 302 is moved around the fixed rod 301 to rotate in the direction of the fixed frame 304, until the active 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 active gear 307 to rotate, and the driven gear 303 meshed with it will also be driven to rotate, and at the same time, the lifting mechanism 100, the drilling mechanism 400 and the angle adjustment mechanism 600 located 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 then the rotation can be stopped; When the drill bit 401 is rotated to the drilling direction, the connecting frame 302 is moved to drive the driving gear 307 and the rotating wheel 306 to leave the fixed frame 304, and the handle 309 is released at the same time. Under the self-reset function of the spring 311, the block 305 is rebounded and lowered, and the locking teeth 312 set on the surface of the block 305 are engaged with the tooth grooves of the driven gear 303, so that the driven gear 303, the lifting mechanism 100, the drilling mechanism 400 and the angle adjustment mechanism 600 are fixed so that they will not easily rotate autonomously. 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 arranged at the four corners of the workbench 200, one or more auxiliary adjustment mechanisms 500 can be adjusted according to the 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 fixing ring 504, the screw rod 502 cannot be lifted or lowered. However, the screw rod 502 will rotate inside the storage groove 505 opened inside the leg 501 during the rotation process. Because the storage groove 505 has threads inside, the screw rod 502 will extend or shrink the distance between it and the leg 501 when it rotates, so that one corner of the workbench 200 will be raised or lowered, thereby achieving the effect of auxiliary adjustment of the inclination angle of the drill bit 401. 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, so when the connecting gear 106 rotates, the active plate 104 will also rotate, and the active plate 104 will move to the drilling motor. When the active plate 104 rotates in the direction of the drilling motor 403, the drill bit 401 will be lowered. When the active plate 104 rotates in the direction of the drilling motor 403, the driven plate 103 will be pressed by the pressure plate 102 fixed outside the active plate 104. 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, the lifting rod 110 will move along the slide groove 107, so as to ensure that the drill bit 401 will not be easily offset when the drilling work is carried out. 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 rotating 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.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
