[0067] In this embodiment, it should also be noted that the sawing assembly can be replaced with a drilling assembly, that is, the sawing machine becomes a drilling machine, which can be used for drilling operations before sawing the stone body. Figure 5 , 6 , 10, 12, 13, and 14, the structure of the drilling assembly is as follows: the drilling assembly 156 includes a drill rod 174, a sleeve assembly 169, and a transmission shield 176. The sleeve assembly 169 is longitudinally arranged, and the circumferential sides of the front and rear ends thereof are respectively connected to the telescopic ends of the telescopic arm 133. The transmission shield 176 is provided with a driven wheel 181 and a driving wheel 182 with a belt drive at intervals. One end of the transmission shield is connected to the sleeve assembly, and the other end is provided with a drilling motor 173. A rotating shaft 172 is provided in the sleeve assembly, and the driven wheel is installed on the rotating shaft. The driving wheel is installed on the output shaft of the drilling motor. The rear end of the drill rod is connected to the front end of the rotating shaft, and the front end of the drill rod is provided with a coring drill bit 175. Since a lifting mechanism is provided between the upper and lower bodies, when the drilling machine needs to change the drilling position, the upper body is lowered to a certain height, so that the subsequent centering adjustment can be more stable and the convenience of centering adjustment can be improved.

[0068] In the drilling machine, a through hole A177 is provided at one end of the transmission shield for the rotating shaft to extend into, and a through hole B178 is provided at the other end for the drilling motor output shaft to extend into. A tension adjustment plate 184 is provided at one end of hole B on the transmission shield, and a through hole C185 is provided in the middle of the tension adjustment plate for the output shaft of the drilling motor to make way. The drilling motor is installed on the tension adjustment plate, and the four corners of the tension adjustment plate are provided with adjustment strip holes 186. Bolt holes 179 corresponding to the adjustment strip holes are provided on the transmission shield. The transmission shield is connected to the tension adjustment plate by bolts passing through the adjustment strip holes and the bolt holes. The transmission belt 183 will deform and become loose after being used for a period of time, affecting the transmission effect and needs to be replaced. The service life of the transmission belt is not high. The setting of the adjustment strip hole allows the output shaft position of the drilling motor to be adjusted, thereby adjusting the tension of the transmission belt, ensuring stable transmission, and improving the service life of the transmission belt.

[0069] In the drilling machine, the sleeve assembly 169 includes a front cylinder 171 and a rear cylinder 170. Connecting flanges 180 are provided at both ends of the through hole A on the transmission shield 176. The transmission shield is located between the front cylinder and the rear cylinder. Flange parts are provided on the outer periphery of the rear end of the front cylinder and the front end of the rear cylinder. The flange parts are screwed to the connecting flanges. The rotating shaft is installed in the front cylinder, and a bearing seat for installing the rotating shaft is installed at the end of the front cylinder.

[0070] In this embodiment, the rear end of the drill rod is provided with an internal pipe thread, the front end of the rotating shaft is provided with an external pipe thread, and the drill rod is threadedly connected with the external pipe thread via the internal pipe thread.

[0071] In this embodiment, the rear end of the rotating shaft extends into the transmission shield, and a rotating joint is installed at the rear end of the rotating shaft for connecting to a water supply system.

[0072] In the drilling machine, a coring drill bit broken tooth detection assembly is provided on the liftable frame, and the coring drill bit broken tooth detection assembly includes a controller installed on the frame 100 and a pressure sensor 187 sleeved on the rotating shaft. The pressure sensor and the drilling motor are electrically connected to the controller. The pressure sensor is arranged on the front side of the sleeve assembly. A sensor support bearing 188 is arranged between the pressure sensor and the sleeve assembly. The front end of the pressure sensor abuts against the drill rod, and the rear end abuts against the sensor support bearing. The sensor support bearing abuts against the sleeve assembly. When the coring drill bit breaks teeth during the drilling process, the pressure sensor detects the pressure change transmitted from the rotating rod and feeds back to the controller, and the controller controls the drilling motor to stop. The pressure sensor detects the pressure change of the drill rod during the drilling process, thereby determining whether the coring drill bit has broken teeth, and facilitating the timely replacement of the coring drill bit.

[0073] In the drilling machine, the end of the sleeve assembly is provided with a recessed groove for accommodating the sensor support bearing and the rear end of the pressure sensor.

[0074] The sawing machine and the drilling machine in this embodiment are used independently. When working, one drilling machine first drills a hole in the soil and stone body with the core drill bit on the left and right sides of the liftable frame. After the drilling machine finishes working, the front end of the sawing arm of the other sawing machine is aligned with the hole opening, and the two sawing ropes of the sawing machine saw the stone body at the same time.

[0075] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except when it is obviously impossible to use an integrated molding process).

[0076] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the present invention include states or shapes that are approximate, similar, or close to them.

[0077] Any component provided by the present invention may be assembled from a plurality of separate components, or may be a separate component manufactured by an integral forming process.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
