[0034] In this embodiment, the drilling rig includes a power head 100, a support frame 200, a hydraulic mechanism, a sleeve mechanism and a lifting and propulsion mechanism. By installing a column 201 on the support frame 200, the power head 100 is installed on the sleeve mechanism and then sleeved on the outer side of the column 201. At the same time, a lifting and propulsion mechanism is correspondingly installed on the column 201. The sleeve mechanism and the power head 100 are driven by the lifting and propulsion mechanism to work. The entire drilling rig is powered by a hydraulic mechanism installed on the support frame 200. Power provided by the hydraulic mechanism can effectively avoid factors such as lack of electricity in the field that affect the use of the drilling rig. At the same time, since the drilling rig has fewer components and redundant components are removed, the overall structure is lighter, which can be convenient for rapid installation, disassembly and transportation, can greatly reduce labor intensity, save manpower, and can be widely used in sampling operations in complex field conditions.

[0035] Among them, preferably, the power head uses air circulation drilling technology and diamond drilling technology, and does not require mud circulation during the drilling process, so it can quickly drill holes and take rock powder and core samples, thereby facilitating and being widely used in sampling operations in field mountain geological surveys.

[0036] Furthermore, the support frame 200 includes a base 202 and a frame 203 , the base 202 is arranged on a fixed surface, the frame 203 is pinned to the frame 203 , the column 201 is pinned to the base 202 , and the hydraulic mechanism is installed on the frame 203 .

[0039] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the hydraulic mechanism includes an engine 300 and a hydraulic press 301, the engine 300 and the hydraulic press 301 are installed at intervals on the support frame 200, and the engine 300 and the hydraulic press 301, and the hydraulic press 301 and the lifting and propulsion mechanism are all connected through hydraulic pipe transmission.

[0040] In this embodiment, the hydraulic mechanism includes an engine 300 and a hydraulic device 301, and the engine 300 and the hydraulic device 301 are installed at intervals on the frame 203 of the support frame 200. The engine 300 is selected as a gasoline engine 300, and the hydraulic device 301 is driven to rotate by the engine 300. Since the hydraulic device 301 and the lifting and propulsion mechanism are connected through a hydraulic pipe transmission, the lifting and propulsion mechanism can be driven to work by the hydraulic device 301, and the sliding sleeve mechanism and the power head 100 can be driven to work by the lifting and propulsion mechanism. The entire driving process uses the hydraulic device 301 as the power source, which can effectively avoid factors such as lack of electricity in the field that affect the use of the drilling rig, so that it can be widely used in sampling operations in complex field conditions.

[0041] Furthermore, the hydraulic mechanism also includes a controller, and the controller is electrically connected to the hydraulic machine.

[0042] In this embodiment, the hydraulic press is electrically connected to the controller, and the staff directly controls the hydraulic press through the controller, thereby driving the lifting and propulsion mechanism to work, so as to achieve the purpose of controlling the sliding sleeve mechanism and the power head 100.

[0043] Among them, preferably, the controller can also be a control console, which can be set on the frame 203 together with the hydraulic press, or can be externally connected to a fixed surface. Similarly, the staff can also directly control the hydraulic press through the control console, so it will not be repeated here.

[0044] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the lifting and propulsion mechanism includes a lifting power assembly, which is arranged at the bottom end of the column 201. One end of the lifting power assembly is connected to the hydraulic device 301, and the other end is connected to the sliding sleeve mechanism, which is used to drive the sliding sleeve mechanism to slide along the extension direction of the column 201.

[0045] In this embodiment, the lifting and propulsion mechanism includes a lifting power assembly, which is arranged at the bottom end of the column 201. The lifting power assembly is connected to the hydraulic press 301, and the lifting power assembly is directly driven by the hydraulic press 301 to operate. The lifting power assembly drives the sliding sleeve mechanism to slide along the extension direction of the column 201, thereby completing the lifting and lowering of the power head 100.

[0046] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the sliding sleeve mechanism includes a sliding member 400 and a sprocket assembly. The sliding member 400 is sleeved on the outside of the column 201. The sprocket assembly is arranged along the extension direction of the column 201 and is connected to the sliding member 400.

[0047] In this embodiment, the sliding member 400 is sleeved on the outside of the column 201, and the sprocket assembly is connected to the sliding member 400, and the sprocket assembly is arranged along the extension direction of the column 201. The sprocket assembly is driven by the lifting power assembly to transmit, thereby driving the sliding member 400 connected to the sprocket assembly to move along the extension direction of the column 201.

[0048] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the sprocket assembly includes at least two pulleys 401 and a chain. The pulleys 401 are arranged at intervals along the extension direction of the column 201. The chain passes through the pulleys 401 and the sliding member 400 in sequence, and the chain drives the sliding member 400 to move synchronously.

[0049] In this embodiment, the pulleys 401 are arranged at intervals along the extension direction of the column 201, wherein preferably, a pulley 401 is provided at the top and bottom ends of the column 201, respectively. Correspondingly, a pulley 401 can be added in the middle of the column 201 according to actual usage conditions to ensure the transmission effect. The chain passes through the pulley 401 and the sliding member 400 in sequence. When in use, the pulley 401 rotates to drive the chain to rotate, and finally drives the sliding member 400 to move synchronously to achieve the effect of lifting and lowering the power head 100.

[0050] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the lifting power assembly includes a lifting motor 500 , which is disposed at the bottom end of the column 201 . The lifting motor 500 is connected to the hydraulic device 301 , and the output shaft is connected to the pulley 401 at the bottom end of the column 201 .

[0051] In this embodiment, the lifting power assembly includes a lifting motor 500, which is directly installed at the bottom end of the column 201. Accordingly, the lifting motor 500 is connected to the hydraulic pressure 301, and the lifting motor 500 is driven to rotate by the hydraulic pressure 301. Since the output shaft of the lifting motor 500 is connected to the pulley 401 arranged at the bottom end of the column 201, it can drive the pulley 401 connected thereto to rotate, and then drive the chain to rotate. Through linkage, other pulleys 401 can be driven to rotate together. At the same time, since the chain passes through the sliding member 400, the chain can drive the sliding member 400 to move synchronously. By controlling the lifting motor 500 to rotate forward and reverse, the lifting and lowering of the power head 100 can be completed.

[0052] According to an embodiment provided by the present invention, Figure 1 and Figure 2 As shown, the lifting and propulsion mechanism also includes a rotary power assembly, which is arranged on the power head 100. One end of the rotary power assembly is connected to the hydraulic device 301, and the other end is connected to the power head 100, which is used to drive the power head 100 to operate.

[0053] In this embodiment, the lifting and propulsion mechanism includes a rotary power assembly, which is installed on the power head 100. The rotary power assembly is connected to the hydraulic press 301, and the rotary power assembly is directly driven by the hydraulic press 301 to operate. And because the rotary power assembly is installed on the power head 100, it can be directly connected to the power head 100 and drive the power head 100 to rotate, thereby driving the power head 100 to complete the drilling operation of the drilling rig.

[0054] According to an embodiment provided by the present invention, Figure 1 and Figure 2As shown, the rotary power assembly includes a rotary motor 501 , which is disposed on the power head 100 . The rotary motor 501 is connected to the hydraulic press 301 , and the output shaft is connected to the power head 100 .

[0055] In this embodiment, the rotary power assembly includes a rotary motor 501, which is directly installed above the power head 100. Accordingly, the rotary motor 501 is connected to the hydraulic cylinder 301, and the rotary motor 501 is driven to rotate by the hydraulic cylinder 301. Since the output shaft of the rotary motor 501 is connected to the power head 100, it can drive the power head 100 to rotate. By controlling the rotary motor 501 to rotate, the drilling operation of the power head 100 can be completed.

[0056] In this embodiment, the engine 300 drives the hydraulic cylinder 301 through a coupling to convert mechanical energy into liquid pressure energy. The high-pressure oil output by the hydraulic cylinder 301 drives the lifting motor 500 and the rotary motor 501 through the reversing valve, so that the lifting motor 500 and the rotary motor 501 convert the liquid pressure into mechanical energy, thereby realizing the rotation, pressurization and lifting of the drilling rig. The entire driving process does not require electric drive, which can ensure that the drilling rig provided in this embodiment will not be unable to be used normally due to lack of electricity in the field, thereby ensuring that it can fully adapt to sampling operations in various complex conditions.
