Description

Technical Field

[0001] This utility model relates to the field of drilling equipment technology, specifically a geological drilling device. Background Technology

[0002] Geological drilling, a crucial component of geological exploration and engineering construction, utilizes specialized equipment to drill boreholes underground, obtaining physical data such as rock cores and soil samples. This provides critical data support for geological structure analysis, mineral resource exploration, hydrogeological surveys, and infrastructure construction. With the ever-increasing demands of resource development and engineering construction, higher requirements are being placed on the performance, efficiency, and adaptability of geological drilling equipment.

[0003] According to a search, Chinese patent document CN220319468U discloses a geological drilling device. During drilling, a second motor placed on a motor base is activated. The second motor drives a second threaded rod to rotate, moving it downwards on the worktable. This rotation, via a connecting seat, causes the entire drill bit assembly to rotate, initiating drilling. When drill bit replacement is required, the second motor is ensured to be off. The fixing ring is rotated to remove it from the fixing claw. Then, the third threaded rod is rotated, causing it to move downwards. This movement, via a third connecting piece, drives the secondary hinge rod to rotate. The secondary hinge rod, through the main hinge rod, drives the fixing claw to rotate, causing it to expand outwards and disengage the exploration drill bit. The drill bit can then be removed for replacement and maintenance.

[0004] However, the aforementioned drilling equipment, as well as most drilling equipment on the market, is typically large in size, making it inconvenient to move and transport, and hindering the quick connection of drill pipes. Therefore, we propose a geological drilling device to solve these problems. Utility Model Content

A first connecting plate is fixedly connected to the upper surface of the base plate. A second connecting plate is hinged to the inner side of the first connecting plate. An arc-shaped clamping plate is fixedly connected to the bottom end of the second connecting plate.

[0009] Preferably, one end of the transverse lead screw is fixedly connected to a rotating handle, and the transverse lead screw is rotatably connected to the outer surface of the vertical plate relative to one end of the rotating handle.

[0010] Preferably, the top surface of the base plate has a through-hole for the drill rod body to pass through, and the drill rod body includes two key bars fixedly connected to the outer surface.

[0013] Preferably, a transmission rod is rotatably connected between the two sides of the top frame, and four sets of casters are installed on the lower surface of the base plate.

[0014] Compared with the prior art, the present invention provides a geological drilling device with the following advantages:

[0015] 1. This utility model can drive the horizontal lead screw to rotate by rotating the handle, thereby moving the sliding sleeve. Under the action of the diagonal brace, it can erect or fold the guide rod, top frame and other components. Drilling can be carried out in the erected state, and the height of the device can be effectively reduced after folding, which is convenient for transportation and carrying.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 A geological drilling device includes a base plate 1, two side plates 2 fixedly connected to the upper surface of the base plate 1, a support plate 3 hinged between the two side plates 2, a guide rod 4 fixedly connected to the top surface of the support plate 3, a top frame 5 fixedly connected to the top of the guide rod 4, a movable plate 6 slidably connected to the outer surface of the guide rod 4, a gasoline engine bracket 7 bolted to the top of the movable plate 6, a four-stroke gasoline engine 8 mounted on the top of the gasoline engine bracket 7, a gear commutator 9 connected to the output end of the four-stroke gasoline engine 8, a drill pipe joint 10 fixedly connected to the output end of the gear commutator 9, a drill pipe body 11 threadedly connected to the bottom of the drill pipe joint 10, a vertical plate 12 fixedly connected to the side wall of the side plates 2, and a fixed connection between the top surface of the base plate 1 and the support plate 3. A second vertical plate 13 is connected to the first vertical plate 12. A horizontal lead screw 14 is rotatably connected between the first vertical plate 12 and the second vertical plate 13. A sliding sleeve 15 is threadedly connected to the outer surface of the horizontal lead screw 14. A diagonal brace 16 is hinged to the outer surface of the sliding sleeve 15. A side lug 17 is hinged to the top of the diagonal brace 16. A vertical lead screw 18 is threadedly connected to the inside of the moving plate 6. A worm gear 19 is fixedly connected to the outer surface of the vertical lead screw 18. A worm 20 is drivenly connected to the outer surface of the worm gear 19. A transmission rod 21 is fixedly connected to both ends of the worm 20. A handwheel 22 is fixedly connected to one end of the transmission rod 21. A connecting plate 23 is fixedly connected to the upper surface of the base plate 1. A second connecting plate 24 is hinged to the inner side of the first connecting plate 23. An arc-shaped clamping plate 25 is fixedly connected to the bottom end of the second connecting plate 24.

[0024] Specifically, one end of the transverse lead screw 14 is fixedly connected to a handle 26, and the transverse lead screw 14 is rotatably connected to the outer surface of the vertical plate 12 relative to one end of the handle 26.

[0025] The advantage is that by manually turning the handle 26 clockwise, the transverse lead screw 14 can be rotated, which in turn drives the sliding sleeve 15 to move. The sliding sleeve 15 then drives the end of the diagonal brace 16 that is hinged to the sliding sleeve 15 to move. In this way, the diagonal brace 16 can gradually lift the side ear 17. The side ear 17 then drives the top frame 5, which in turn drives the two guide rods 4. The guide rods 4 drive the support plate 3 to rotate around the axis that connects to the side plate 2. The overall structure can erect the guide rods 4, the top frame 5, and other components, and then erect the gasoline engine bracket 7, the four-stroke gasoline engine 8, and other components, so that subsequent drilling work can be carried out. When the entire drilling device needs to be transported, the handle 26 is turned counterclockwise, which ultimately drives the guide rods 4, the four-stroke gasoline engine 8, and other components to fold up, thus reducing the height of the device and making it easier to transport and carry.

[0026] Specifically, a circular hole is provided through the top surface of the base plate 1 for the drill rod body 11 to pass through. The drill rod body 11 includes two key bars 110 fixedly connected to the outer surface.

[0027] Specifically, the top surface of the arc-shaped card plate 25 has a rectangular slot 251, and a handle 252 is fixedly connected to the top surface of the arc-shaped card plate 25.

[0028] Specifically, the gear commutator 9 is bolted to the side wall of the gasoline engine bracket 7, and the upper surface of the arc-shaped clamping plate 25 is fixedly connected to the connecting plate 24 near the arc-shaped surface.

[0029] The advantage is that when the drill rod body 11 penetrates deep into the soil during drilling, and the two key strips 110 on the outer surface of the drill rod body 11 are in the round holes opened on the top surface of the base plate 1, the handle 252 is used to drive the arc-shaped clamping plate 25 to rotate around the axis connecting the connecting plate 1 23 and the connecting plate 24. In this way, the arc-shaped clamping plate 25 can be flipped over, and the two arc-shaped clamping plates 25 are symmetrically laid flat on the top surface of the base plate 1. The two arc-shaped clamping plates 25 are exactly around the round holes on the top surface of the base plate 1. The rotation direction is changed by operating the gear reversing device 9. At this time, the four-stroke gasoline engine 8 is started and drives the drill rod joint 10 to rotate in the opposite direction. The drill rod connector 10 is threadedly connected to the drill rod body 11, and the two key bars 110 on the outer surface of the drill rod body 11 can be locked by the rectangular slot 251. Therefore, when the drill rod connector 10 rotates in the opposite direction, it can gradually separate from the drill rod body 11. Then, by turning the handwheel 22 counterclockwise, the four-stroke gasoline engine 8 and other components are driven to rise. Then, a new drill rod body 11 is taken out and connected to the drill rod connector 10. The new drill rod body 11 can also be threadedly connected to the drill rod body 11 that is buried in the soil. The overall structure does not require any additional tools, which makes it easy to connect the drill rod body 11 in order to achieve a suitable drilling depth.

[0030] Specifically, the transmission rod 21 is rotatably connected between the two sides of the top frame 5, and four sets of moving wheels are installed on the lower surface of the base plate 1.

[0031] The advantage is that during drilling, the four-stroke gasoline engine 8 is started, which drives the output shaft of the gear commutator 9 to rotate. The output shaft of the gear commutator 9 drives the drill pipe joint 10 to rotate, which in turn drives the drill pipe body 11 to rotate. The drill bit is connected to the bottom end of the drill pipe body 11, so the drill bit rotates to drill through the soil. During this process, the handwheel 22 needs to be manually turned clockwise to drive the transmission rod 21 to rotate. The transmission rod 21 drives the worm gear 20 to rotate, which drives the worm wheel 19 to rotate. The worm wheel 19 drives the vertical lead screw 18 to rotate. Under the guidance of the two guide rods 4, the vertical lead screw 18 drives the moving plate 6 to descend. In this way, the moving plate 6 drives the gasoline engine support 7 to move, which in turn drives the four-stroke gasoline engine 8 and the gear commutator 9 to move downward. Thus, the drill pipe body 11 has a downward rotational force, which in turn drives the drill bit to drill downward.

[0032] In use, firstly, manually turn the handle 26 clockwise to rotate the transverse lead screw 14, causing the sliding sleeve 15 to move. This moves the side lug 17 via the diagonal brace 16, erecting components such as the guide rod 4 and the top frame 5. Next, start the four-stroke gasoline engine 8, which drives the output shaft of the gear commutator 9 to rotate, thereby rotating the drill pipe joint 10 and the drill pipe body 11. Simultaneously, manually turn the handwheel 22 clockwise, which drives the vertical lead screw 18 to rotate via the transmission rod 21, worm gear 20, and worm wheel 19, causing the moving plate 6 to descend and rotating the drill pipe body 11 downwards to drill into the soil. When the drill pipe body 11 is deep into the soil and the key bar 110 is at the base... When the drill rod is inside the round hole on the top surface of plate 1, use handle 252 to rotate the arc-shaped clamping plate 25 and lay it flat around the round hole on the top surface of base plate 1. Change the rotation direction through gear reversing device 9, start the four-stroke gasoline engine 8 to make the drill rod joint 10 rotate in the opposite direction to separate it from the drill rod body 11; then, turn the handwheel 22 counterclockwise to drive the four-stroke gasoline engine 8 and other components to rise; finally, take out the new drill rod body 11 and connect it to the drill rod joint 10. The new drill rod body 11 is threadedly connected to the drill rod body 11 that is buried in the soil; finally, if the device needs to be transported, turn the handle 26 counterclockwise to fold the guide rod 4, four-stroke gasoline engine 8 and other components to reduce the height of the device.
