[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1: Please refer to Figure 1-Figure 9 As shown, in the prior art, facing complex and changeable geological conditions and ores with different hardness, the existing drilling method is prone to the problem of slow drilling speed, which can be solved by the following solutions:

[0038] In this embodiment, a mobile drilling device suitable for prospecting engineering includes a drilling vehicle body 1. The drilling vehicle body 1 is moved to a designated drilling position to achieve rapid drilling construction in different prospecting areas. A fixed seat 11 is installed on the drilling vehicle body 1 for movable installation of a lifting seat 2, and a lifting seat 2 is movably installed on the fixed seat 11. The lifting seat 2 moves on the fixed seat 11 to drive a rotating drum 22 and a drill bit 23 to perform drilling processing. The lifting seat 2 is slidably connected with a movable seat 21.

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

[0040] The lifting seat 2 is provided with a driving assembly 3, which includes a mounting frame 31 fixedly connected to the lifting seat 2, a rotating shaft 32 for driving the rotating cylinder 22 to reciprocate and lift motion is rotatably connected to the mounting frame 31, a gear 1 33 is fixedly connected to the rotating shaft 32, a gear 2 34 meshing with the gear 1 33 is fixedly connected to the rotating rod 24, the rotating shaft 32 drives the rotating rod 24 to carry the drill bit 23 to rotate through the meshing gear 1 33 and the gear 2 34, and the end of the rotating rod 24 passes through the mounting frame 31 and is slidably connected thereto, so as to further improve the rotation stability of the rotating rod 24;

[0041] An auxiliary component 4 is provided inside the drill bit 23, and the auxiliary component 4 includes a plurality of auxiliary crushing disks 41 which are rotatably connected to the bottom of the drill bit 23 and distributed in a circular array. When the drill bit 23 rotates for drilling, the drill bit 23 synchronously drives the auxiliary crushing disks 41 to revolve, and then the auxiliary crushing disks 41 synchronously rotate, thereby accelerating the drilling speed of the prospecting project. The auxiliary crushing disks 41 and the bottom of the drill bit 23 are fixedly connected with a plurality of crushing heads. By installing the crushing heads on the auxiliary crushing disks 41 and the drill bit 23, the ore can be effectively crushed when the drill bit 23 and the auxiliary crushing disks 41 rotate.

[0042] Guide rods 12 slidably connected to the lifting seat 2 are fixedly connected to both sides of the fixed seat 11 through support rods, which are used to increase the stability of the lifting seat 2 during movement and avoid the shaking of the rotating cylinder 22 during the drilling process. A support plate 13 welded to the drilling vehicle body 1 is hinged on the guide rod 12, and a hydraulic cylinder 14 is hinged between the fixed seat 11 and the drilling vehicle body 1;

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

[0044] A lifting screw rod 16 threadedly connected to the lifting seat 2 is rotatably connected to the fixed seat 11, and a reduction motor 17 for driving the lifting screw rod 16 to rotate is bolted to the fixed seat 11. The reduction motor 17 drives the lifting screw rod 16 to rotate slowly, and the lifting screw rod 16 pushes the rotating cylinder 22 to slowly descend.

[0045] A guide protrusion 1 26 is fixedly connected to the outer wall of the rotating cylinder 22 and located above the movable seat 21. A limit plate 38 is fixedly connected to the rotating shaft 32, and a guide protrusion 2 39 that matches the guide protrusion 1 26 is fixedly connected to one side of the top of the limit plate 38. The cross-sections of the guide protrusion 1 26 and the guide protrusion 2 39 are both isosceles or right-angled trapezoidal structures. After the two are in contact, they can be forced to move away from each other, thereby realizing the lifting movement of the rotating cylinder 22.

[0046] The rotating cylinder 22 is lifted by rotating the guide protrusion 2 39 carried by the rotating shaft 32 and intermittently contacting the guide protrusion 1 26 on the rotating cylinder 22. After the guide protrusion 2 39 is separated from the guide protrusion 1 26, the rotating cylinder 22 and the drill bit 23 move downward rapidly under their own weight, causing the drill bit 23 to impact the bottom of the borehole, and performing additional impact and crushing processing on the bottom of the borehole except for the rotation of the auxiliary crushing disk 41, thereby further improving the drilling efficiency of the ore.

[0047] A rotating rod 42 is fixedly connected to the auxiliary crushing disk 41, and the rotating rod 42 is fixedly connected to a 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 meshing with the gear 45 is provided on the outer wall of the rotating cylinder 22. When the drill bit 23 drives multiple groups of auxiliary crushing disks 41 to revolve, the external tooth groove 29 provided on the outer side of the rotating cylinder 22 meshes with the gear 45, so that the auxiliary crushing disk 41 is caused to rotate rapidly while rotating, thereby accelerating the drilling speed of the prospecting project.

[0048] An inclined feed trough 210 is provided at the bottom of the drill bit 23 and between two adjacent sets of auxiliary crushing discs 41. The crushed fine ore particles, combined with the rotation of the drill bit 23, enter the interior of the rotating cylinder 22 through the multiple inclined feed troughs 210 provided on the drill bit 23, and a baffle 211 is hinged on one side of the feed trough 210 to contact the other side.

[0049] The ore particles in the feed trough 210 are continuously accumulated, thereby pushing the corresponding baffle 211 to flip upward and enter the rotating cylinder 22. When the rotating cylinder 22 is rising, a small portion of the ore particles in the feed trough 210 below the baffle 211 will fall out directly, and the baffle 211 will return to its original position and flip downward with the help of the gravity of the ore particles above it, causing its free side to contact the feed trough 210, thereby limiting the discharge of the ore particles in the rotating cylinder 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 by the rotating spiral blade 212 to rise in the rotating cylinder 22, and are 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 in the figure, the problem that the crushed ore particles are not easy to enter the rotating drum due to the rapid reciprocating lifting movement of the rotating drum, thereby reducing the drilling and discharge efficiency, can be solved by the following solutions:

[0052] In this embodiment, an outer toothed ring 25 is fixedly connected to the outer wall of the rotating cylinder 22 and located below the movable seat 21. A transmission rod 35 is rotatably connected to the lifting seat 2, and a gear 3 36 meshing with the outer toothed ring 25 and the gear 1 33 is fixedly connected to the transmission rod 35. The diameter of the gear 3 36 is smaller than the diameter of the gear 1 33, and the diameter of the outer toothed ring 25 is much larger than the diameter of the gear 1 33, so that when the rotating shaft 32 rotates quickly, the rotating cylinder 22 rotates slowly.

[0053] When the rotating shaft 32 rotates, the transmission rod 35 is driven to rotate through the meshing gear 1 33 and the gear 3 36 above the lifting seat 2. The transmission rod 35 drives the rotating cylinder 22 to rotate slowly through the meshing outer gear ring 25 and the gear 3 36 below the lifting seat 2. A driving motor 37 for driving the rotating shaft 32 to rotate is bolted to the mounting frame 31, and the driving motor 37 drives the rotating shaft 32 to rotate.

[0054] A guide protrusion 1 26 is fixedly connected to the outer wall of the rotating cylinder 22 and located above the movable seat 21, a limit plate 38 is fixedly connected to the rotating shaft 32, and a guide protrusion 2 39 matching with the guide protrusion 1 26 is fixedly connected to one side of the top of the limit plate 38;

[0055] The rotating cylinder 22 and the rotating shaft 32 rotate slowly in the same direction but at different speeds. By utilizing the rotation of the two in the same direction but at different speeds, the limit plate 38 carrying the guide protrusion 2 39 can rotate several circles before it can contact the guide protrusion 1 26. The guide protrusion 2 39 contacts the guide protrusion 1 26. The position of the hour hand and the minute hand at six o'clock on the clock can be referred to to increase the interval time between two adjacent rises and falls of the rotating cylinder 22, thereby further ensuring the sufficient crushing effect of the auxiliary crushing disk 41 on the surrounding area.

[0056] An opening stop ring 27 that matches the stop disk 38 is fixedly connected to the outer wall of the rotating cylinder 22. The guide protrusion 1 26 is located directly above the opening of the opening stop ring 27. The opening size of the opening stop ring 27 is larger than the size that the stop disk 38 can pass through. After the guide protrusion 2 39 contacts the guide protrusion 1 26, the stop disk 38 moves downward relatively through the opening of the opening stop ring 27 to avoid motion interference. The tops of both ends of the opening stop ring 27 are provided with guide slopes 28.

[0057] After the guide protrusion 29 is separated from the guide protrusion 1 26, the rotating cylinder 22 is carried by the rotation of the opening limit ring 27, and the bottom edge of the limit plate 38 is combined with the guide inclined surface 28 at the end of the opening limit ring 27 to force the rotating cylinder 22 to have a downward reset movement. Combined with the lifting screw 16, the lifting seat 2 is forced to slowly descend, and the drilling force is continued to be applied to the bottom of the drill hole. The limit plate 38 is then located at the top of the opening limit ring 27 to drive the drill bit 23 to apply a force to the bottom of the drill hole when the lifting screw 16 causes the rotating cylinder 22 to descend. At the same time, when the guide protrusion 29 contacts the guide protrusion 1 26, it promotes the upward movement of the rotating cylinder 22, providing a clearance space;

[0058] The rotating shaft 32 drives the limit plate 38 to rotate rapidly in the same direction as the rotating cylinder 22. After the opening of the open limit ring 27 on the rotating cylinder 22 rotates to the bottom of the limit plate 38, the limit plate 38 carries the guide protrusion 2 39 to rotate several circles. When the guide protrusion 2 39 synchronously rotates to the top of the opening on the open limit ring 27, the guide protrusion 2 39 contacts the guide protrusion 1 26, prompting the rotating cylinder 22 to move upward. After the guide protrusion 2 39 separates from the guide protrusion 1 26, the rotating cylinder 22 and the drill bit 23 move downward rapidly under their own weight, and the drill bit 23 impacts the bottom of the borehole, and the bottom of the borehole is impacted and crushed except for the rotation of the auxiliary crushing disk 41.

[0059] A rotating rod 42 is fixedly connected to the auxiliary crushing disk 41, and the rotating rod 42 is fixedly connected to a 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 outer tooth groove 29 meshing with the gear 45 is provided on the outer side wall of the rotating cylinder 22. The drill bit 23 is used to drive multiple groups of auxiliary crushing disks 41 to revolve, and with the help of the rotation of the rotating cylinder 22, the meshing gear 45 and the outer tooth groove 29 are combined, and the multiple auxiliary crushing disks 41 are prompted to rotate circumferentially and quickly rotate at the same time, further accelerating the rotation speed of the auxiliary crushing disks 41, so that when the rotating cylinder 22 is reciprocatingly lifted and lowered, the auxiliary crushing disks 41 fully crush the area around the bottom of the drill bit 23 to assist the crushing effect of the drill bit 23 on the remaining areas after it descends.

[0060] Example 3: Please refer to Figure 1-Figure 9 As shown, the present invention also provides a method for using a mobile drilling device suitable for prospecting 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 carrying the rotating cylinder 22 to a vertical state, the reduction motor 17 drives the lifting screw 16 to rotate slowly, and the lifting screw 16 pushes the rotating cylinder 22 to slowly descend;

[0062] Step 2: The driving motor 37 drives the rotating shaft 32 to rotate. The rotating shaft 32 drives the rotating rod 24 to carry the drill bit 23 to rotate through the meshing gear 1 33 and the gear 2 34. 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 drive the rotating cylinder 22 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 4 45 and the outer tooth groove 29, the multiple auxiliary crushing disks 41 are caused to rotate circumferentially and quickly rotate at the same time, so as to perform auxiliary crushing and drilling processing on the ore;

[0063] Step 3: The rotating shaft 32 drives the limit plate 38 to rotate rapidly in the same direction as the rotating cylinder 22. After the opening of the open limit ring 27 on the rotating cylinder 22 rotates to the bottom of the limit plate 38, the limit plate 38 carries the guide protrusion 2 39 to rotate several circles. When the guide protrusion 2 39 synchronously rotates to the top of the opening on the open limit ring 27, the guide protrusion 2 39 contacts the guide protrusion 1 26, prompting the rotating cylinder 22 to move upward. After the guide protrusion 2 39 separates from the guide protrusion 1 26, the rotating cylinder 22 and the drill bit 23 move downward rapidly under their own weight, and the drill bit 23 impacts the bottom of the borehole, and the bottom of the borehole is impacted and crushed except for the rotation of the auxiliary crushing disk 41.

[0064] After the guide protrusion 2 39 is completely separated from the guide protrusion 1 26, the opening limit ring 27 is rotated with the rotating cylinder 22, and the limit plate 38 cooperates with the guide inclined surface 28 at the end of the opening limit ring 27, so as to force the rotating cylinder 22 to move downward, and the lifting screw 16 is combined to promote the slow downward movement of the lifting seat 2, so as to continuously apply the drilling force to the bottom of the drill hole, thereby accelerating 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 to flip upward and then enter the rotating cylinder 22. Combined with the rotating spiral blades 212, the ore particles in the rotating cylinder 22 are driven to move upward, and then discharged through the discharge port 213 on the rotating cylinder 22. During the rising process of the rotating cylinder 22, a small part of the ore particles in the feed trough 210 will fall out directly, and the baffle 211 will reset and flip downward with the help of the gravity of the ore particles above it, causing its free side to resist the feed trough 210, limiting the discharge of ore particles in the rotating cylinder 22, and then continuing the discharge of ore particles.

[0066] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
