The limit rod 76 is inserted into the limit hole to limit and fix the fixing rod 73 to prevent it from rebounding. Then the T-shaped plug block 72 can be separated, so that the drill head 8 can be removed, so that when the device is in use, it is easy to disassemble and assemble the drill head 8 for maintenance or replacement.

[0031] Specifically, a fixing hole matching the fixing rod 73 is formed on one side of the T-shaped plug block 72 , and an inserting hole and a limiting hole matching the limiting rod 76 are formed above the fixing rod 73 .

[0032] By adopting the above technical solution, the fixing hole facilitates the insertion of the fixing rod 73 to fix the T-shaped plug block 72, the insertion hole facilitates the insertion of the limiting rod 76 to strengthen the fixation of the fixing rod 73, and the limiting hole facilitates the insertion of the limiting rod 76 to limit and fix the fixing rod 73 to prevent it from rebounding when pulled out.

[0033] Specifically, a stabilizing slide bar is slidably disposed on one end of the fixed slide block 74 , and a stabilizing slide bar is also slidably disposed on one end of the limiting slide block 77 .

[0034] By adopting the above technical solution, the stabilizing slide bar facilitates the stable sliding of the fixed slide block 74 and the limiting slide block 77.

[0035] When the present embodiment is in use: the limiting rod 76 is pulled, the limiting rod 76 drives the limiting slider 77 to move and compress the limiting spring 78, so that the limiting rod 76 is disengaged from the insertion hole; then the fixing rod 73 is pulled, the fixing rod 73 drives the fixing slider 74 to move and compress the fixing spring 75, so that the fixing rod 73 is disengaged from the fixing rod 73 and moves to the limiting hole. When the limiting rod 73 is moved to coincide with the limiting hole and the limiting rod 76, the limiting rod 76 is inserted into the limiting hole to limit and fix the fixing rod 73 to prevent it from rebounding; then the T-shaped plug 72 can be separated, thereby removing the drill head 8, so that when the device is in use, it is convenient to disassemble and assemble the drill head 8 for maintenance or replacement.

[0036] The structures and operating principles of the mast assembly 1, lifting assembly 2, pressure - applying and vibrating assembly 3, drill pipe 5, power assembly 6, and drill bit 8 in the present utility model have been disclosed in a vibration - pressurized rotary drilling rig with Chinese patent application number 202223506286.X. Its working principle is that the electrical equipment used in this device is controlled by an external controller. The mast assembly 1 can move smoothly driven by the crawler vehicle, facilitating walking and transportation, and being convenient for aligning the hole during operation. The drill bit 8 is guided by the mast assembly 1, which can improve the verticality. The mast assembly 1 is movably connected to the crawler vehicle through a luffing mechanism, enabling the mast assembly 1 to continuously adjust its own angle during the drilling process as the depth of the hole changes. At the top of the mast assembly 1, there is a multi - pulley rope - winding goose head. A steel wire rope is wound around the multi - pulley rope - winding goose head. One end of the steel wire rope is fixedly connected to the cross - plate, and the other end of the steel wire rope is connected to the hoisting mechanism on the crawler vehicle. The drill bit 8 is lifted and lowered through the hoisting mechanism on the crawler vehicle, the multi - pulley rope - winding goose head, and the steel wire rope. The power head motor starts to work, and the power head motor drives the rotary power head to rotate. The rotary power head rotates to apply torque and pressure to the drill pipe 5. The drill pipe 5 drives the drill bit 8 to rotate and move downward for drilling and excavation. At the same time, the motor starts to work. The output end of the motor drives the transmission shaft to rotate, and the transmission shaft drives the U - shaped transmission rod to rotate. The rotation of the U - shaped transmission rod drives the pressure - applying connecting rod to move up and down. The pressure - applying connecting rod drives the pressure - applying disc to move up and down. The pressure - applying disc drives the buffer support rod, buffer disc, and buffer spring to move up and down. When the buffer disc moves downward and contacts the mounting round table, a downward force is applied to the mounting round table, drill pipe 5, and drill bit 8, intermittently applying a downward force to the drill pipe 5 assembly, preventing long - term collision with hard rocks, preventing damage to the drill pipe 5 assembly, increasing the service life of the drill pipe 5 assembly, and improving work efficiency. When the buffer disc contacts the mounting round table, the buffer disc applies pressure to the buffer support rod and buffer spring. The buffer spring deforms and contracts under the pressure, and at the same time, the telescopic contraction of the buffer support rod can buffer the impact force. Moreover, the stroke of the buffer support rod and buffer spring is shorter than that of the pressure - applying connecting rod, which will not affect the application of the downward force and prevent the impact force from damaging the equipment, increasing the service life of the equipment. When dealing with the soil and rock in the drill bit 8, the soil and rock in the drill bit 8 can be discharged through the vibration force, facilitating soil unloading and improving work efficiency.

[0037] The working principle and use process of the utility model: when the utility model is used, it is connected to the crawler vehicle through the mast assembly 1, and then it can be used. When in use, the drill rod 5 and the drill head 8 are driven downward by the lifting component 2, and the pressure vibration component 3 and the power component 6 cooperate to work. When in use, the motor of the device is conveniently protected by the protective component 4, and the drill head 8 is conveniently disassembled and maintained by the disassembly component 7. When the protective component 4 is in use, the protective cover 41 is installed by the fixing seat 42 and the bolt, so that the motor is protected by the protective cover 41. When the protective cover 41 is in use, the cooling fan 43 is started, and the wind is filtered through the filter 44 and then enters to dissipate the heat inside. When the filter 44 needs to be cleaned, the cleaning motor is started 45, drives the cleaning brush plate 46 to rotate, cleans the filter screen 44, so that the device is convenient for protecting the motor when in use, and improves the practicality of use. When the disassembling and assembling component 7 is in use, the limiting rod 76 is pulled, and the limiting rod 76 drives the limiting slider 77 to move and compress the limiting spring 78, so that the limiting rod 76 is disengaged from the insertion hole, and then the fixing rod 73 is pulled, and the fixing rod 73 drives the fixing slider 74 to move and compress the fixing spring 75, so that the fixing rod 73 is disengaged from the fixing rod 73. When the fixing rod 73 moves to the limiting hole and the limiting rod 76 coincides, the limiting rod 76 is inserted into the limiting hole, and the fixing rod 73 is limited and fixed to prevent it from rebounding. Then the T-shaped plug block 72 can be separated, so that the drill head 8 can be removed, so that the device is convenient for disassembling and assembling the drill head 8 for maintenance or replacement when in use.
