[0002] A geological drilling rig uses mechanical energy to send the drill bit or drill rod into the ground for drilling operations. The drill tool is first sent into the wellbore, and the rotating head and turntable provide power to drive the drill bit to rotate, breaking the rock formation. At the same time, the mud pump injects mud into the wellbore to bring the broken rock formation out to the ground. Geological drilling rigs are mainly used in various fields such as mineral exploration, geological exploration, and petroleum exploration.

[0003] The existing drilling rigs still have the following problems during use: the drilling rigs have fixed operating heights and strict working surface requirements in geological exploration operations, and cannot operate in limited spaces. This leads to limited application scenarios of the drilling rigs. At the same time, the debris splashing when the drilling rigs operate in special sites may accidentally injure workers. Utility Model Content

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0023] The utility model provides Figure 1-4 A geological drilling device shown includes a machine platform 1, characterized in that the bottom of the machine platform 1 is rotatably connected to an off-road tire 2, so that the height of the whole machine is reduced. Compared with the crawler, the tire has strong maneuverability and flexible steering, and is suitable for working on hard ground. The four corners of the machine platform 1 are fixedly connected to hydraulic support legs 3, the top of the machine platform 1 is fixedly connected to a telescopic frame 4, and the top of the telescopic frame 4 is fixedly connected to a cross plate 5, and a drill motor 6 is fixedly embedded inside the cross plate 5, and the working position of the drill 7 is adjusted by the telescopic frame 4. The output shaft of the drill motor 6 is connected to the drill 7 for driving the drill 7 to work, and the drill 7 passes through the through hole 9 reserved inside the machine platform 1, and also includes:

[0024] The splash-proof assembly 8 and the bottom wall of the horizontal plate 5 are fixedly connected with a splash-proof bucket 1 81, the top of the splash-proof bucket 1 81 is fixedly sleeved on the outer ring of the drill motor 6, and the splash-proof bucket 1 81 is movably connected with a splash-proof bucket 2 82, an observation window 821 is embedded in the splash-proof bucket 2 82, and the bottom of the splash-proof bucket 2 82 is fixedly connected with a base 83, and the base 83 is placed on the plate body of the machine 1 on both sides of the through hole 9. After the splash-proof bucket 2 82 descends and contacts the top surface of the machine 1, the splash-proof area formed by the splash-proof bucket 1 81 and the splash-proof bucket 2 82 prevents debris from splashing when the drill 7 is operating, thereby preventing accidental injury to the staff.

[0025] There are two telescopic frames 4, and the two telescopic frames 4 are symmetrically arranged with reference to the inner central axis of the through hole 9 as the symmetry axis, and the top ends of the two telescopic frames 4 are fixedly connected to the left and right ends of the cross plate 5 respectively, which is convenient for adjusting the overall height of the drilling rig, and the telescopic frames 4 only occupy the space of the drilling rig body, and can be extended and retracted according to the actual construction conditions to achieve the advantage of ideal working conditions.

[0026] The top of the splash-proof bucket 81 is closed and the bottom is open, and a movable groove 86 with an open bottom is reserved inside the barrel body of the splash-proof bucket 81, and the inner wall of the movable groove 86 is in contact with the outer wall of the splash-proof bucket 82 and is slidably connected up and down to ensure the movable connection between the splash-proof bucket 81 and the splash-proof bucket 82 so as to form a closed area later.

[0027] The splash-proof bucket 1 81 and the splash-proof bucket 2 82 and the fixed end of the telescopic frame 4 are at the same height.

[0028] The splash-proof bucket 82 is through-through from top to bottom, and the top outer wall of the splash-proof bucket 82 is fixedly connected with two limit blocks 84 symmetrically arranged with reference to the central axis of the splash-proof bucket 82 as the symmetry axis, and the limit blocks 84 move inside the limit grooves 85 reserved inside the splash-proof bucket 81, and the limit grooves 85 are connected with the movable grooves 86. The limit blocks 84 ensure the stability of the up and down movement of the splash-proof bucket 81 and the splash-proof bucket 82.

[0029] The diameter of the through hole 9 is larger than the diameter of the drill bit 7 , which makes it easier for the drill bit 7 to pass through the machine platform 1 for drilling operations.

[0030] Working principle: when using a geological drilling rig device, first start the hydraulic support leg 3 to ensure the stability of the entire machine platform 1 during operation, then start the telescopic frame 4 to drive the cross plate 5 and the drill motor 6 and drill bit 7 fixedly installed inside the cross plate 5 to start and descend at the same time to perform the operation. During the descent of the drill motor 6 and the drill bit 7, the splash-proof bucket 1 81 and the splash-proof bucket 2 82 are driven to descend synchronously. The splash-proof bucket 1 81 and the splash-proof bucket 2 82 are movably connected. After the splash-proof bucket 2 82 descends and contacts the top surface of the machine platform 1, the splash-proof area formed by the splash-proof bucket 1 81 and the splash-proof bucket 2 82 prevents debris from splashing during the operation of the drill bit 7 and causing accidental injuries to the staff. The continuous descent of the drill bit 7 drives the splash-proof bucket 1 81 to movably descend on the outer circle of the splash-proof bucket 2 82, so that the descent operation of the drill bit 7 is not affected while the splash-proof area is formed;

[0031] At the same time, the machine drive adopts off-road tires 2, and the height of the whole machine is reduced. Compared with crawler tracks, the tires have strong maneuverability and flexible steering, which are suitable for working on hard ground and more conducive to working in low space. The tires are off-road with a ground clearance of 280mm, which also ensures that the off-road capability of traditional crawler tracks is not reduced after replacing the tires. The drill rod of the drill bit 7 is 1m in specification, which has the advantages of small working space requirements and precise drilling depth. The use of drill rods of this specification can ensure that the operation height is only 2.5m and the drill rod can still be lowered and taken out to meet the construction needs.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
