Description

Technical Field

[0001] This invention relates to the field of drilling equipment technology, and in particular to a mobile drilling device suitable for mineral exploration engineering. Background Technology

[0002] Drilling rigs, as key mechanical equipment for drilling operations beneath the Earth's surface, have a wide range of applications, including geological exploration, mineral resource development, hydrogeological surveys, foundation construction, and oil and gas extraction. The design and function of these rigs vary depending on the specific application and drilling conditions. However, regardless of type, drilling rigs typically include the following core components: a robust frame structure, a power drive unit, a drill rod to transmit torque, and a drill bit for direct drilling operations.

[0003] For example, in the prior art, a mineral geological exploration drilling device with the publication number CN116677313A, although the combination of the sampling tube and the drill bit inside can meet the basic drilling construction needs in the exploration project, when facing hard ore, the device relies solely on the rotation of the drill bit for drilling, which often makes it difficult to complete the task quickly and efficiently. In particular, when facing complex and variable geological conditions and ores with varying hardness, this traditional drilling method may encounter problems such as slow drilling speed and increased energy consumption.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a mobile drilling device suitable for mineral exploration engineering to solve the aforementioned technical defects. This invention uses a drive component to drive the drill bit and the rotating cylinder to rotate in opposite directions at a differential speed. First, it causes the rotating cylinder to move synchronously and intermittently, which can impact and crush the bottom of the borehole to improve the drilling efficiency of ore. Then, combined with the rotation of the rotating cylinder, it drives multiple auxiliary crushing discs in the auxiliary component to revolve around the center of the hole and rotate rapidly on their own axis. The auxiliary crushing discs fully crush the area around the bottom of the drill bit to assist the overall crushing effect after the drill bit descends, further improving the drilling efficiency.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A mobile drilling device suitable for mineral exploration engineering includes a drilling vehicle body, a fixed seat installed on the drilling vehicle body, a lifting seat movably installed on the fixed seat, a movable seat slidably connected to the lifting seat, a rotating cylinder rotatably connected to the movable seat, a drill bit rotatably installed at the bottom of the rotating cylinder, and a rotating rod fixedly connected to the drill bit and rotatably connected to the rotating cylinder.

[0008] The lifting seat is provided with a drive assembly, which includes a mounting frame fixedly connected to the lifting seat, a rotating shaft for driving the rotating cylinder to reciprocate and lift, a gear one fixedly connected to the rotating shaft, and a gear two meshing with the gear one fixedly connected to the rotating rod.

[0009] The drill bit is equipped with an auxiliary component, which includes multiple sets of auxiliary crushing discs rotatably connected to the bottom of the drill bit and arranged in a circular array. Each auxiliary crushing disc is fixedly connected to the bottom of the drill bit with multiple crushing heads.

[0010] Preferably, the fixed base has guide rods that are slidably connected to the lifting base on both sides by support rods, and a support plate that is welded to the drilling vehicle body is hinged on the guide rod. A hydraulic cylinder is hinged between the fixed base and the drilling vehicle body, and an auxiliary placement frame is welded to the top of the drilling vehicle body.

[0011] Preferably, a lifting screw that is threadedly connected to the lifting seat is rotatably connected to the fixed base, and a reduction motor for driving the lifting screw to rotate is bolted to the fixed base.

[0012] Preferably, an external gear ring is fixedly connected to the outer wall of the rotating cylinder and below the movable seat; a transmission rod is rotatably connected to the lifting seat; and a gear three that meshes with the external gear ring and gear one is fixedly connected to the transmission rod; and a drive motor for driving the rotating shaft to rotate is bolted on the mounting bracket.

[0013] Preferably, a guide protrusion one is fixedly connected to the outer wall of the rotating cylinder and above the movable seat, a limiting disk is fixedly connected to the rotating shaft, and a guide protrusion two that cooperates with the guide protrusion one is fixedly connected to one side of the top of the limiting disk.

[0014] Preferably, an open limiting ring that cooperates with the limiting plate is fixedly connected to the outer wall of the rotating cylinder, the guide protrusion is located directly above the opening of the open limiting ring, and guide inclined surfaces are provided at the top of both ends of the open limiting ring.

[0015] Preferably, a rotating rod is fixedly connected to the auxiliary crushing disc, and the rotating rod is fixedly connected to a rotating shaft through a universal joint coupling. The rotating shaft is rotatably connected to the drill bit, and a gear four is fixedly connected to the rotating shaft. An external tooth groove that meshes with the gear four is opened on the outer wall of the rotating cylinder.

[0016] Preferably, the bottom of the drill bit and between two adjacent sets of auxiliary crushing discs are provided with inclined feed troughs, and one side of the feed trough is hinged to a baffle that contacts the other side.

[0017] Preferably, a spiral blade is fixedly connected to the rotating rod and located inside the rotating cylinder, and a discharge port is fixedly connected to the top of one side of the rotating cylinder.

[0018] The beneficial effects of this invention are as follows:

[0019] (1) The drilling vehicle body of the present invention moves to the designated drilling position of the exploration project. First, the rotating cylinder and the drill bit are slowly lowered by the lifting seat. Then, the drill bit is rotated by the rotating shaft combined with gear one and gear two. The drill bit drives the auxiliary crushing disc to revolve. Combined with the external tooth groove and gear four, the auxiliary crushing disc is rotated synchronously, thereby accelerating the drilling speed of the exploration project. The ore particles generated by drilling enter the rotating cylinder through the feed groove on the drill bit. The rotating rod carries the spiral blades to rotate in the rotating cylinder, and the ore particles are discharged synchronously. In addition, the rotating cylinder is lifted by the intermittent contact between the guide protrusion two on the rotating shaft and the guide protrusion one on the rotating cylinder. The rotating cylinder and the drill bit move rapidly downward under their own weight, causing the drill bit to impact the bottom of the borehole. The bottom of the borehole is subjected to additional impact crushing treatment in the area other than the revolve of the auxiliary crushing disc, which further improves the drilling efficiency of the ore.

[0020] (2) The present invention utilizes the rotation of the rotating cylinder to accelerate the rotation speed of the auxiliary crushing disc, so that when the rotating cylinder reciprocates and impacts, the auxiliary crushing disc fully crushes the area around the bottom of the drill bit, thereby assisting the crushing effect on the remaining area after the drill bit descends; and through the combination of the rotating shaft with gear one, gear three and external gear ring, the rotating cylinder and the rotating shaft are driven to rotate slowly in the same direction. By utilizing the rotation of the two in the same direction but at different speeds, the limiting disc carrying the guide protrusion two rotates several times before it can contact the guide protrusion one, thereby increasing the interval time between two adjacent lifting and lowering of the rotating cylinder, and further ensuring the crushing effect of the auxiliary crushing disc on the surrounding area.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figures 1-9 As shown, existing drilling methods often suffer from slow drilling speeds when faced with complex and varied geological conditions and ores of varying hardness. This can be addressed through the following solutions:

[0038] This embodiment describes a mobile drilling device suitable for mineral exploration engineering, including a drilling vehicle body 1. The drilling vehicle body 1 is moved to a designated drilling position to achieve rapid drilling construction in different mineral exploration areas. A fixed seat 11 is installed on the drilling vehicle body 1 for the movable installation of a lifting seat 2. The lifting seat 2 is movably installed on the fixed seat 11. By moving the lifting seat 2 on the fixed seat 11, the rotating cylinder 22 and the drill bit 23 are driven to perform drilling. A movable seat 21 is slidably connected to the lifting seat 2.

[0039] The movable seat 21 is used for the lifting and lowering movement of the rotating cylinder 22. Limiting blocks are symmetrically fixedly connected to the outer side walls of the movable seat 21. Limiting grooves that are slidably connected to the corresponding limiting blocks are opened on the inner side wall of the lifting seat 2 to avoid the problem of the movable seat 21 and the lifting seat 2 separating when the fixed seat 11 is in the vertical state. The rotating cylinder 22 is rotatably connected to the movable seat 21. A drill bit 23 is rotatably installed at the bottom of the rotating cylinder 22, and a rotating rod 24 that is rotatably connected to the drill bit 23 is fixedly connected to the drill bit 23.

[0040] The lifting base 2 is provided with a drive assembly 3. The drive assembly 3 includes a mounting frame 31 fixedly connected to the lifting base 2. A rotating shaft 32 for driving the rotating cylinder 22 to reciprocate and lift is rotatably connected to the mounting frame 31. A gear 33 is fixedly connected to the rotating shaft 32. A gear 34 meshing with the gear 33 is fixedly connected to the rotating rod 24. The rotating shaft 32 drives the rotating rod 24 to rotate, carrying the drill bit 23, through the meshing gear 33 and gear 34. The end of the rotating rod 24 passes through the mounting frame 31 and is slidably connected to it, further improving the rotational stability of the rotating rod 24.

[0041] The drill bit 23 is equipped with an auxiliary component 4 inside. The auxiliary component 4 includes multiple sets of auxiliary crushing discs 41 that are rotatably connected to the bottom of the drill bit 23 and distributed in a ring array. When the drill bit 23 rotates to drill, the drill bit 23 synchronously drives the auxiliary crushing discs 41 to revolve around the sun and then rotate synchronously on their own axis, thereby accelerating the drilling speed of the exploration project. Multiple crushing heads are fixedly connected to the bottom of the auxiliary crushing discs 41 and the drill bit 23. Through the crushing heads installed on the auxiliary crushing discs 41 and the drill bit 23, the ore can be effectively crushed when the drill bit 23 and the auxiliary crushing discs 41 rotate.

[0042] The two sides of the fixed seat 11 are fixedly connected to the guide rods 12 that are slidably connected to the lifting seat 2 by the support rods. This is used to increase the stability of the lifting seat 2 during the movement process and to avoid the problem of the rotating cylinder 22 shaking during the drilling process. The guide rod 12 is hinged to the support plate 13 that is welded to the drilling vehicle body 1. The fixed seat 11 and the drilling vehicle body 1 are hinged to the hydraulic cylinder 14.

[0043] The drilling vehicle body 1 moves to the designated drilling position, the piston rod of the hydraulic cylinder 14 extends, and pushes the fixed seat 11 to carry the rotating cylinder 22 to a vertical position to prepare for drilling. An auxiliary placement frame 15 is welded to the top of the drilling vehicle body 1. The auxiliary placement frame 15 is used to provide stable support for the fixed seat 11 when it is placed horizontally, and at the same time, it provides convenience for the movement of the drilling vehicle body 1.

[0044] A lifting screw 16 is rotatably connected to the fixed base 11 and threadedly connected to the lifting base 2. A geared motor 17 for driving the lifting screw 16 to rotate is bolted to the fixed base 11. The geared motor 17 drives the lifting screw 16 to rotate slowly, and the lifting screw 16 pushes the rotating cylinder 22 to move slowly downward.

[0045] A guide protrusion 26 is fixedly connected to the outer wall of the rotating cylinder 22 and above the movable seat 21. A limiting disk 38 is fixedly connected to the rotating shaft 32, and a guide protrusion 39 that cooperates with the guide protrusion 26 is fixedly connected to one side of the top of the limiting disk 38. The cross-sections of the guide protrusion 26 and the guide protrusion 39 are both isosceles or right trapezoidal structures, which can force them to separate after they come into contact, thereby realizing the lifting movement of the rotating cylinder 22.

[0046] The rotating shaft 32 carries the second guide protrusion 39 to rotate and intermittently contacts the first guide protrusion 26 on the rotating cylinder 22, thereby lifting the rotating cylinder 22. After the second guide protrusion 39 separates from the first guide protrusion 26, the rotating cylinder 22 and the drill bit 23 move rapidly downward under their own weight, causing the drill bit 23 to impact the bottom of the borehole. This provides additional impact crushing treatment to the area at the bottom of the borehole other than the area where the auxiliary crushing disc 41 rotates, further improving the drilling efficiency of the ore.

[0047] A rotating rod 42 is fixedly connected to the auxiliary crushing disc 41, and the rotating rod 42 is fixedly connected to the rotating shaft 44 through the universal joint coupling 43. The rotating shaft 44 is rotatably connected to the drill bit 23, and a gear 45 is fixedly connected to the rotating shaft 44. An external tooth groove 29 that meshes with the gear 45 is opened on the outer wall of the rotating cylinder 22. While the drill bit 23 drives multiple sets of auxiliary crushing discs 41 to revolve, the engagement of the external tooth groove 29 on the outer side of the rotating cylinder 22 with the gear 45 causes the auxiliary crushing discs 41 to rotate rapidly while rotating on their own axis, thereby accelerating the drilling speed of the exploration project.

[0048] The bottom of the drill bit 23 and between the two adjacent sets of auxiliary crushing discs 41 are provided with inclined feed chute 210. The crushed fine ore particles, combined with the rotation of the drill bit 23, enter the rotating cylinder 22 through the multiple inclined feed chute 210 on the drill bit 23. A baffle 211 is hinged on one side of the feed chute 210 and contacts the other side.

[0049] As the ore particles in the feed trough 210 accumulate, they push the corresponding baffle 211 upwards and into the rotating drum 22. As the rotating drum 22 rises, a small portion of the ore particles located below the baffle 211 in the feed trough 210 will fall out directly. The baffle 211 will be reset and flipped downwards by the gravity of the ore particles above it, causing its free side to abut against the feed trough 210, thereby restricting the discharge of ore particles from the rotating drum 22.

[0050] A spiral blade 212 is fixedly connected to the rotating rod 24 and located inside the rotating cylinder 22. A discharge port 213 is fixedly connected to the top of one side of the rotating cylinder 22. The ore particles entering the rotating cylinder 22 are driven to rise by the rotating spiral blade 212 and then automatically discharged through the discharge port 213 on the rotating cylinder 22.

[0051] Example 2: Please refer to Figure 5 and Figure 7 As shown, the problem that the rapid reciprocating lifting motion of the rotating drum makes it difficult for crushed ore particles to enter the rotating drum, thus reducing drilling and discharge efficiency, can be solved by the following solutions:

[0052] In this embodiment, an external gear ring 25 is fixedly connected to the outer wall of the rotating cylinder 22 and below the movable seat 21. A transmission rod 35 is rotatably connected to the lifting seat 2, and a gear 36 that meshes with the external gear ring 25 and gear 33 is fixedly connected to the transmission rod 35. The diameter of gear 36 is smaller than that of gear 33, and the diameter of the external gear ring 25 is much larger than that of gear 33, so that when the rotating shaft 32 rotates rapidly, the rotating cylinder 22 rotates slowly.

[0053] When the rotating shaft 32 rotates, it drives the transmission rod 35 to rotate through the meshing gear 33 and the gear 36 above the lifting seat 2. The transmission rod 35 drives the rotating cylinder 22 to rotate slowly through the meshing external gear ring 25 and the gear 36 below the lifting seat 2. The mounting bracket 31 is bolted with a drive motor 37 for driving the rotating shaft 32 to rotate. The drive motor 37 drives the rotating shaft 32 to rotate.

[0054] A guide protrusion 26 is fixedly connected to the outer wall of the rotating cylinder 22 and above the movable seat 21. A limiting disk 38 is fixedly connected to the rotating shaft 32, and a guide protrusion 39 that cooperates with the guide protrusion 26 is fixedly connected to one side of the top of the limiting disk 38.

[0055] The rotating cylinder 22 and the rotating shaft 32 rotate slowly in the same direction but at different speeds. By using their rotation in the same direction but at different speeds, the limiting disk 38 carrying the guide protrusion 29 rotates several times before it can contact the guide protrusion 1 26. The contact between the guide protrusion 2 39 and the guide protrusion 1 26 can be referenced to the position of the hour and minute hands at six o'clock on a clock. This increases the interval time between two adjacent rises and falls of the rotating cylinder 22, further ensuring the full crushing effect of the auxiliary crushing disk 41 on the surrounding area.

[0056] An open limiting ring 27 that cooperates with the limiting disk 38 is fixedly connected to the outer wall of the rotating cylinder 22. The first guide protrusion 26 is located directly above the opening of the open limiting ring 27. The opening size of the open limiting ring 27 is larger than the size that the limiting disk 38 can pass through. After the second guide protrusion 39 contacts the first guide protrusion 26, the limiting disk 38 moves downward relative to the opening of the open limiting ring 27 to avoid motion interference. The top of both ends of the open limiting ring 27 is provided with guide slopes 28.

[0057] After the guide protrusion 29 separates from the guide protrusion 126, as the rotating cylinder 22 rotates carrying the opening limiting ring 27, the guide inclined surface 28 at the bottom edge of the limiting plate 38 combined with the end of the opening limiting ring 27 forces the rotating cylinder 22 to have a downward reset force. Combined with the lifting screw 16 causing the lifting seat 2 to slowly descend, the drilling force continues to be applied to the bottom of the borehole. Then, the limiting plate 38 is located at the top of the opening limiting ring 27, so that when the lifting screw 16 causes the rotating cylinder 22 to descend, it drives the drill bit 23 to apply force to the bottom of the borehole. At the same time, it provides clearance space for the rotating cylinder 22 to rise when the guide protrusion 29 contacts the guide protrusion 126.

[0058] The rotating shaft 32 drives the limiting disk 38 and the rotating cylinder 22 to rotate rapidly in the same direction. After the opening of the limiting ring 27 on the rotating cylinder 22 rotates to below the limiting disk 38, the limiting disk 38 carries the second guide protrusion 39 to rotate several times. When the second guide protrusion 39 rotates synchronously to above the opening on the limiting ring 27, the second guide protrusion 39 contacts the first guide protrusion 26, causing the rotating cylinder 22 to move upward. After the second guide protrusion 39 separates from the first guide protrusion 26, the rotating cylinder 22 and the drill bit 23 move rapidly downward under their own weight. The drill bit 23 impacts the bottom of the borehole, and performs impact crushing treatment on the area of ​​the bottom of the borehole except for the area rotated by the auxiliary crushing disk 41.

[0059] A rotating rod 42 is fixedly connected to the auxiliary crushing disc 41, and the rotating rod 42 is fixedly connected to the rotating shaft 44 through a universal joint coupling 43. The rotating shaft 44 is rotatably connected to the drill bit 23, and a gear 45 is fixedly connected to the rotating shaft 44. An external tooth groove 29 that meshes with the gear 45 is opened on the outer wall of the rotating cylinder 22. The drill bit 23 drives multiple sets of auxiliary crushing discs 41 to revolve. With the help of the rotation of the rotating cylinder 22, the meshing gear 45 and the external tooth groove 29 are combined to cause multiple auxiliary crushing discs 41 to rotate rapidly on their own axis while rotating circumferentially, further accelerating the rotation speed of the auxiliary crushing discs 41. When the rotating cylinder 22 reciprocates and impacts, the auxiliary crushing discs 41 fully crush the area around the bottom of the drill bit 23 to assist the drill bit 23 in crushing the remaining area after it descends.

[0060] Example 3: Please refer to Figures 1-9 As shown, the present invention also proposes a method for using a mobile drilling device suitable for mineral exploration engineering, comprising the following steps:

[0061] Step 1: The drilling vehicle body 1 moves to the designated drilling position, the piston rod of the hydraulic cylinder 14 extends, pushing the fixed seat 11 to carry the rotating cylinder 22 to a vertical position, the reduction motor 17 drives the lifting screw 16 to rotate slowly, and the lifting screw 16 pushes the rotating cylinder 22 to move slowly downward.

[0062] Step 2: The drive motor 37 drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the rotating rod 24 to rotate through the meshing gear 1 33 and gear 2 34, carrying the drill bit 23. Through the meshing gear 1 33 and the corresponding upper gear 3 36, and the outer gear ring 25 and the corresponding lower gear 3 36, the rotating cylinder 22 is driven to rotate slowly in the opposite direction. With the help of the drill bit 23 and the rotating cylinder 22 rotating in the opposite direction, and in combination with the meshing gear 45 and the outer gear groove 29, multiple auxiliary crushing discs 41 are made to rotate circumferentially and rotate rapidly on their own axis at the same time, so as to perform auxiliary crushing and drilling treatment on the ore.

[0063] Step 3: The rotating shaft 32 drives the limiting disk 38 and the rotating cylinder 22 to rotate rapidly in the same direction. After the opening of the limiting ring 27 on the rotating cylinder 22 rotates to below the limiting disk 38, the limiting disk 38 carries the second guide protrusion 39 to rotate several times. When the second guide protrusion 39 rotates synchronously to above the opening on the limiting ring 27, the second guide protrusion 39 contacts the first guide protrusion 26, causing the rotating cylinder 22 to move upward. After the second guide protrusion 39 separates from the first guide protrusion 26, the rotating cylinder 22 and the drill bit 23 move downward rapidly under their own weight. The drill bit 23 impacts the bottom of the borehole, and performs impact crushing treatment on the area of ​​the bottom of the borehole except for the area rotated by the auxiliary crushing disk 41.

[0064] After the second guide protrusion 39 is completely separated from the first guide protrusion 26, it rotates with the opening limiting ring 27 carried by the rotating cylinder 22. Combined with the guide inclined surface 28 at the end of the opening limiting ring 27 and the limiting plate 38, the rotating cylinder 22 is forced to have a downward force. Combined with the lifting screw 16, the lifting seat 2 is slowly lowered, and a drilling force is continuously applied to the bottom of the borehole to accelerate the drilling speed.

[0065] Step 4: The crushed fine ore particles enter the multiple feed troughs 210 on the drill bit 23, and push the corresponding baffles 211 upward to flip and enter the rotating drum 22. Then, combined with the rotating spiral blades 212, the ore particles in the rotating drum 22 are driven to rise and then discharged through the discharge port 213 on the rotating drum 22. During the upward movement of the rotating drum 22, a small portion of the ore particles in the feed troughs 210 will fall directly out. The baffles 211 will be reset and flipped downward by the gravity of the ore particles above them, causing their free side to abut against the feed troughs 210, restricting the discharge of ore particles in the rotating drum 22, thereby continuously discharging ore particles.

[0066] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
