[0019] 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.

[0020] Example 1 See also Figure 1 - Figure 4 , the present invention provides a technical solution: a mechanical trenching machine for geological tunnel construction, comprising a trenching mechanism 1, the trenching mechanism 1 is composed of an adjusting sleeve 11, a drilling head 12 and a trenching disc 13; A processing cavity is provided on the side wall of the adjusting sleeve 11, and a groove plate 13 is installed in the processing cavity. A plurality of drilling heads 12 are arranged around the surface of the groove plate 13. The plurality of drilling heads 12 are arranged on the groove plate 13, and side wall brackets 121 are respectively installed on both sides of the drilling heads 12. A rotating shaft 122 is embedded between the two side wall brackets 121; The outer side wall of the adjusting sleeve 11 is surrounded by a lifting mechanism 2; The lifting mechanism 2 includes a plurality of crushed stone assembly seats 21 mounted on the outer wall of the adjusting sleeve 11, a lifting cylinder 22 is provided in the middle of the crushed stone assembly seat 21, an annular sleeve 23 is installed on the top of the cylinder body of the lifting cylinder 22, an adjusting screw 24 is arranged around the bottom surface of the annular sleeve 23, and a motor fixing ring 25 is installed on the top of the adjusting screw 24; A stone crushing mechanism 3 is installed in the middle of the top of the motor fixing ring 25; The stone crushing mechanism 3 includes a driving motor 31 installed on the top of the motor fixing ring 25, a bevel cutter 32 is installed on the top of the driving motor 31, a saw blade 33 is installed on the top of the bevel cutter 32, a tool connecting base 35 is installed on the top outer wall surface of the saw blade 33 in turn, a stone crushing blade 36 is installed on the top of the tool connecting base 35, and the stone crushing blade 36 is arranged around the outer ring edge of the saw blade 33 through the tool connecting base 35.

[0021] The driving motor 31 is powered on to drive the bevel cutter 32 to rotate, and the stone crushing blade 36 rotates synchronously to cut out the general outline of the tunnel to prevent the stone from collapsing and breaking suddenly.

[0022] When used specifically, step one: trenching work; The user rotates the rotating rod 41 to control the rotation of the slotting disc 13, and when the drilling head 12 contacts the tunnel entrance, the tunnel rocks are removed while stirring. The drilling head 12 is adapted and then the rotating rod 41 is moved. When the slotting disc 13 rotates, the drilling heads 12 gradually remove the mud and sand on the surface of the tunnel due to the deflection of the center of gravity, so as to realize the crushing and excavation of the mine. In order to speed up the crushing work, the multiple drive motors 31 adapted by the adjusting sleeve 11 are used. When the drive motor 31 is driven, the stone crushing blade 36 is driven to rotate. The blade hits the slotting rock layer at high speed, cuts out several crushing points on the side seam of the tunnel, and avoids the slotting rock layer being too large to be cut. The bevel cutter 32 is used for cutting, and the cut stones and mud are stirred and transported again, and the multiple bevel cutters 32 here guide the transportation of crushed stones. Excess crushed stone gradually falls to the outside, realizing mining crushing in underground trenching operation. The material in the crushing stage changes direction according to the axial hinge of the rotating shaft 122 and is removed outside the tunnel to complete the trenching operation. The crushed stone, gravel or mud is transmitted through the groove of the drilling head 12.

[0023] Example 2 Please refer to the instruction manual Figure 5-Figure 7 The difference compared with Example 1 is: An angle adjustment mechanism 4 is installed on the back of the adjustment sleeve 11, and the angle adjustment mechanism 4 is composed of a rotating rod 41, a receiving base 42 and a movable shaft 43; The rotating rod 41 is a driving rotating rod.

[0025] The coordination mechanism 5 includes a spherical connection sleeve 51 arranged on the back of the rotating rod 41. A circular groove 52 is opened in the middle of the spherical connection sleeve 51. A direction-changing ball 53 is embedded in the middle of the circular groove 52. A ball sleeve 54 is sleeved on the surface of the direction-changing ball 53.

[0026] The circular slot 52 and the direction-changing ball 53 are used to change the position of the ball sleeve 54 to achieve free conversion of the inclination position when the angle needs to be changed.

[0027] Step 2: As the trigger of the travel cylinder 73 in the groove cutting work, the angle change of the groove cutting plate 13 is controlled; According to the combined effect of the retracted pipe 75, the articulated base 47 and the movable roller 48, the articulated direction of the connecting rod 44 is changed, and the connecting rod 44 on one side of the pneumatic push will gradually tilt or shorten to reserve space for the drill bit, or extend to push the drill bit toward that side, and use the buffer spring 46 to elastically expand and contract for the purpose of buffering. The articulation of the movable shaft 43 realizes the articulation of the drill bit and the connecting rod 44, and changes the direction of the spherical connection sleeve 51. In actual operation: when the length of the inclination detector 45 in one area changes, the distance The spherical connecting sleeve 51 is hinged in the axial direction of the movable shaft 43, and the direction of the spherical connecting sleeve 51, and the connecting rod 44 at other angles is hinged. The direction-changing ball 53 is caused to roll in the sleeve according to the spherical connecting sleeve 51. The hinge of the direction-changing ball 53 is used as the connection of the spherical connecting sleeve 51, and the specific direction of the end of the groove cutting machine is indirectly changed through the extension of the connecting rod 44. The remaining elastic structures are constrained by the elastic force of the spring, and the respective inclination detectors 45 detect the changed angles of each connecting rod 44 to realize data detection.

During the spraying stage, the scattered dust is gathered and sprayed to improve the dust reduction effect. Liquid is stored in the ultrasonic atomizer tank 69, and the ultrasonic atomizer 691 generated at the bottom is uniformly powered to generate spray water vapor. After the water vapor is replaced, water is discharged from the arc-shaped spray pipe 63 to suppress dust while drilling and prevent it from spreading to the cab behind the machine.
