[0003] The existing drilling machine is mainly composed of four parts: a power machine, a drill rod and a drill bit. During the drilling process, the drill rod usually does not have a stable horizontal structure, which causes the drill bit to deviate during the drilling process, thereby causing the drill bit to deviate and fail to reach the set drilling position, which not only affects the drilling effect, but also results in longer drilling distances after deviation, which not only wastes more energy, but also causes more serious wear of the drill bit and reduces the service life of the drill bit. Therefore, we propose a coal mine geological drilling machine and a method for using the same. Summary of the invention

[0010] Furthermore, the top of the rotating disk contacts the limiting ring, the inner ring surface of the limiting ring is fixedly connected to the inner surface of the annular shell, the side of the triangular block close to the push block is set as an inclined surface, the sides of the four fixed blocks away from the arc-shaped positioning plate are fixedly connected to the inner wall of the annular shell, and the bottom of the rotating disk contacts the top of the fixed block.

[0011] Furthermore, an anti-falling component is arranged on the outside of the connecting rod, and the anti-falling component includes two sleeves, and two arc-shaped clamping blocks are fixedly connected to the inner walls of the two sleeves. Annular clamping grooves are provided on the outer surfaces of the drill rod and the connecting rod, and fixing plates are fixedly connected to the front and back sides of the two sleeves. A limiting block is fixedly connected to the right side of the fixing plate on the left, and the arc-shaped clamping blocks are plugged into the annular clamping grooves.

[0014] A coal mine geological drilling machine, wherein the use method of the coal mine geological drilling machine comprises the following steps:

[0015] Step 1: When it is necessary to connect the connecting rod with the drill rod, the bottom of the connecting rod is threadedly connected with the threaded head at the top of the drill rod. At this time, the stabilizing rod is plugged into the threaded head. When the bottom of the connecting rod contacts the top of the drill rod, the installation of the connecting rod is completed. Then, the two sleeves are docked at the connection between the connecting rod and the drill rod. At the same time, the arc-shaped block on the sleeve will enter the annular groove. When the limit block on the left fixed plate contacts the right fixed plate, the two sleeves are docked. Then, the bolts are inserted from the right fixed plate and threadedly connected with the left fixed plate to fix the two sleeves. This can prevent the drill rod and the connecting rod from falling off. During the drilling process, the drill rod and the connecting rod are subjected to large torque and vibration factors, which may easily lead to the connection between the connecting rod and the drill rod being broken. The sleeve is prevented from falling off after breaking by the cooperation of the arc-shaped block and the annular groove, which is convenient for subsequent maintenance work.

[0016] Step 2: After the connecting rod is connected to the drill rod, during the drilling process, when the annular shell enters the borehole, the motor is started to drive the gear to rotate slowly clockwise, and the gear drives the rotating disk to rotate counterclockwise through the gear ring. The limit ring is used to limit and stabilize the rotating disk, and the push block on the rotating disk will rotate together. When the push block contacts the triangular block, it will push it, and the triangular block will drive the arc positioning plate to move together. At this time, several arc positioning plates expand each other and contact the inner wall of the hole. Then the motor stops, and the arc positioning plate contacts the inner wall of the hole, which can play a positioning role in the drilling process, so that the drilling level moves downward, reducing the occurrence of deviation, thereby reducing the drilling distance, reducing energy consumption, and reducing the wear of the drill bit, and increasing the service life of the drill bit. At the same time, because the arc positioning plate is set in an arc shape, it can better fit the inner wall of the borehole, and the top and bottom of the arc positioning plate are both set in arc surfaces, so it can be smoother when lifting and lowering during the drilling process, and there will be no jamming.

[0017] Step three: When the arc-shaped positioning plate is pushed, it will drive the telescopic rod to slide in the fixed rod and pull the spring. Since the top of the fixed block is in contact with the rotating disk, it can support the rotating disk. When the motor drives the gear to rotate counterclockwise, the rotating disk drives the push block away from the triangular block. At this time, the arc-shaped positioning plate is not pushed, and the telescopic rod is reset under the action of the spring elasticity, and drives the arc-shaped positioning plate to reset, so that the arc-shaped positioning plate is stored in the annular shell.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention sets a stabilizing component. Specifically, after the annular shell enters the borehole, the motor is started to drive the gear to rotate slowly clockwise. The gear then drives the rotating disk to rotate counterclockwise through the gear ring. The push block pushes the triangular block. At this time, a number of arc-shaped positioning plates expand with each other and contact the inner wall of the hole, which can play a positioning role in the drilling process, reduce the occurrence of deviation, thereby reducing the drilling distance, reducing energy consumption, and reducing the wear of the drill bit, thereby increasing the service life of the drill bit.

[0020] (2) The present invention provides an anti-falling component. Specifically, after the connecting rod is connected to the drill rod, the two sleeves are docked at the connection between the connecting rod and the drill rod. At the same time, the arc-shaped clamping block on the sleeve enters the annular clamping groove. Then, the bolt is inserted from the fixing plate on the right side and threadedly connected with the fixing plate on the left side, thereby fixing the two sleeves. The sleeve is prevented from falling after breaking by the cooperation of the arc-shaped clamping block and the annular clamping groove, which facilitates subsequent maintenance work.

[0021] (3) The present invention sets a fixed rod, specifically, the arc-shaped positioning plate drives the telescopic rod to slide in the fixed rod when pushed, and pulls the spring. When the motor drives the gear to rotate counterclockwise, the rotating disk drives the push block away from the triangular block, and the telescopic rod drives the arc-shaped positioning plate to reset under the action of the spring elasticity, so that the arc-shaped positioning plate is stored in the annular shell.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] A coal mine geological drilling machine, and a method for using the coal mine geological drilling machine include the following steps:

[0044] Step 1: When the connecting rod 12 needs to be connected to the drill rod 1, the bottom of the connecting rod 12 is threadedly connected to the threaded head 16 at the top of the drill rod 1. At this time, the stabilizing rod 121 is plugged into the threaded head 16. When the bottom of the connecting rod 12 contacts the top of the drill rod 1, the installation of the connecting rod 12 is completed. Then, the two sleeves 141 are docked at the connection between the connecting rod 12 and the drill rod 1. At the same time, the arc-shaped block 142 on the sleeve 141 will enter the annular groove 17. When the limit block 144 on the left fixing plate 143 contacts the right fixing plate 143, the two sleeves 141 After the docking is completed, the bolt 145 is then inserted from the right fixing plate 143 and threadedly connected with the left fixing plate 143, so that the two sleeve plates 141 are fixed, which can prevent the drill rod 1 and the connecting rod 12 from falling off. During the drilling process, the drill rod 1 and the connecting rod 12 are subjected to factors such as large torque and vibration, which may easily cause the connection between the connecting rod 12 and the drill rod 1 to break. The sleeve plate 141 prevents the sleeve plate 141 from falling off after breaking through the arc-shaped clamping block 142 and the annular clamping groove 17, which is convenient for subsequent maintenance work.

[0045] Step 2: After the connecting rod 12 is connected to the drill rod 1, during the drilling process, when the annular shell 131 enters the borehole, the motor 133 is started to drive the gear 331 to rotate slowly clockwise, and the gear 331 drives the rotating disk 134 to rotate counterclockwise through the gear ring 341. The limit ring 342 is used to limit and stabilize the rotating disk 134, and the push block 343 on the rotating disk 134 will rotate together. When the push block 343 contacts the triangular block 321, it will push it, and the triangular block 321 will drive the arc positioning plate 132 to move together. At this time, a plurality of arc positioning plates 132 expand each other. The arc-shaped positioning plate 132 is in contact with the inner wall of the hole, and then the motor 133 stops, and the arc-shaped positioning plate 132 is in contact with the inner wall of the hole, which can play a positioning role in the drilling process, so that the drilling level moves downward, and the deviation is reduced, thereby reducing the drilling distance, reducing energy consumption, and reducing the wear of the drill bit 11, thereby increasing the service life of the drill bit 11. At the same time, since the arc-shaped positioning plate 132 is set in an arc shape, it can better fit the inner wall of the borehole, and the top and bottom of the arc-shaped positioning plate 132 are both set in an arc surface, so it can be lifted and lowered more smoothly during the drilling process without getting stuck;

[0046] Step three: When the arc-shaped positioning plate 132 is pushed, it will drive the telescopic rod 352 to slide in the fixed rod 351 and pull the spring 353. Since the top of the fixed block 135 is in contact with the rotating disk 134, it can support the rotating disk 134. When the motor 133 drives the gear 331 to rotate counterclockwise, the rotating disk 134 drives the push block 343 away from the triangular block 321. At this time, the arc-shaped positioning plate 132 is not pushed, and the telescopic rod 352 is reset under the elastic action of the spring 353, and drives the arc-shaped positioning plate 132 to reset, so that the arc-shaped positioning plate 132 is stored in the annular shell 131.

[0047] When the connecting rod 12 needs to be connected to the drill rod 1, the bottom of the connecting rod 12 is threadedly connected to the threaded head 16 at the top of the drill rod 1. At this time, the stabilizing rod 121 is plugged into the threaded head 16. When the bottom of the connecting rod 12 contacts the top of the drill rod 1, the installation of the connecting rod 12 is completed. Then, the two sleeves 141 are docked at the connection between the connecting rod 12 and the drill rod 1. At the same time, the arc-shaped block 142 on the sleeve 141 will enter the annular groove 17. When the limit block 144 on the left fixing plate 143 contacts the right fixing plate 143, the two sleeves 141 are docked. After completion, the bolt 145 is then inserted from the right fixing plate 143 and threadedly connected with the left fixing plate 143, thereby fixing the two sleeve plates 141, which can prevent the drill rod 1 and the connecting rod 12 from falling off. During the drilling process, the drill rod 1 and the connecting rod 12 are subjected to factors such as large torque and vibration, which may easily cause the connection between the connecting rod 12 and the drill rod 1 to break. The sleeve plate 141 prevents the sleeve plate 141 from falling off after breaking through the arc-shaped clamping block 142 and the annular clamping groove 17, which is convenient for subsequent maintenance work.

[0048] After the connecting rod 12 is connected to the drill rod 1, during the drilling process, when the annular shell 131 enters the borehole, the motor 133 is started to drive the gear 331 to rotate slowly clockwise, and the gear 331 drives the rotating disk 134 to rotate counterclockwise through the gear ring 341. The limiting ring 342 is used to limit and stabilize the rotating disk 134, and the push block 343 on the rotating disk 134 will rotate together. When the push block 343 contacts the triangular block 321, it will push it, and the triangular block 321 will drive the arc positioning plate 132 to move together. At this time, a plurality of arc positioning plates 132 expand and The arc-shaped positioning plate 132 contacts the inner wall of the hole, and then the motor 133 stops. The arc-shaped positioning plate 132 contacts the inner wall of the hole, which can play a positioning role in the drilling process, so that the drilling level moves downward, reducing the deviation, thereby reducing the drilling distance, reducing energy consumption, and reducing the wear of the drill bit 11, thereby increasing the service life of the drill bit 11. At the same time, since the arc-shaped positioning plate 132 is set in an arc shape, it can better fit the inner wall of the borehole, and the top and bottom of the arc-shaped positioning plate 132 are both set in an arc surface, so it can be lifted and lowered more smoothly during the drilling process without getting stuck.

[0049] When the arc-shaped positioning plate 132 is pushed, the telescopic rod 352 will drive the sliding of the telescopic rod 352 in the fixed rod 351 and pull the spring 353. Since the top of the fixed block 135 is in contact with the rotating disk 134, the rotating disk 134 can be supported. When the motor 133 drives the gear 331 to rotate counterclockwise, the rotating disk 134 drives the pushing block 343 away from the triangular block 321. At this time, the arc-shaped positioning plate 132 is not pushed, and the telescopic rod 352 is reset under the elastic action of the spring 353, and drives the arc-shaped positioning plate 132 to reset, so that the arc-shaped positioning plate 132 is stored in the annular shell 131.

9. A method for using a coal mine geological drilling machine, using the coal mine geological drilling machine as claimed in claim 7, characterized in that: The following steps are involved: Step 1: When it is necessary to connect the connecting rod (12) to the drill rod (1), the bottom of the connecting rod (12) is threadedly connected to the threaded head (16) at the top of the drill rod (1). At this time, the stabilizing rod (121) is plugged into the threaded head (16). When the bottom of the connecting rod (12) contacts the top of the drill rod (1), the installation of the connecting rod (12) is completed. Then, the two sleeves (141) are connected to the connection between the connecting rod (12) and the drill rod (1). At the same time, the arc-shaped block (142) on the sleeve (141) enters the annular groove (17). When the left fixing plate (14 3) After the limit block (144) on the upper side contacts the fixing plate (143) on the right side, the two sleeve plates (141) are connected to each other, and then the bolts (145) are inserted from the fixing plate (143) on the right side and are threadedly connected with the fixing plate (143) on the left side, so that the two sleeve plates (141) are fixed, which can prevent the drill rod (1) and the connecting rod (12) from breaking. The sleeve plate (141) is prevented from falling after breaking by the cooperation of the arc-shaped clamping block (142) and the annular clamping groove (17), which is convenient for subsequent maintenance work; Step 2: After the connecting rod (12) is connected to the drill rod (1), during the drilling process, when the annular shell (131) enters the borehole, the motor (133) is started to drive the gear (331) to rotate slowly clockwise, and the gear (331) drives the rotating disk (134) to rotate counterclockwise through the gear ring (341). The limiting ring (342) is used to limit and stabilize the rotating disk (134), and the push block (343) on the rotating disk (134) will follow As the push block (343) rotates together, it pushes the triangular block (321) after contacting it, and the triangular block (321) drives the arc-shaped positioning plate (132) to move together. At this time, a plurality of arc-shaped positioning plates (132) expand mutually and contact the inner wall of the hole. Then the motor (133) stops, and the arc-shaped positioning plate (132) makes the drilling level move downward. At the same time, because the arc-shaped positioning plate (132) is arranged in an arc shape, it can better fit the inner wall of the drill hole; Step 3: When the arc-shaped positioning plate (132) is pushed, it drives the telescopic rod (352) to slide in the fixed rod (351) and pulls the spring (353). Since the top of the fixed block (135) contacts the rotating disk (134), it can support the rotating disk (134). When the motor (133) drives the gear (331) to rotate counterclockwise, the rotating disk (134) drives the push block (343) away from the triangular block (321). At this time, the arc-shaped positioning plate (132) is not pushed, and the telescopic rod (352) is reset under the elastic action of the spring (353), and drives the arc-shaped positioning plate (132) to reset, so that the arc-shaped positioning plate (132) is stored in the annular shell (131).
