[0031] In the use process of the device, as shown in Figures 1-8 the initial state takes the seat 9 facing the traveling operation table 7 as an example, at this time, the worker can control the tunneling jumbo to move through the traveling operation table 7 to ensure that the tunneling jumbo walks to the working position, in the drilling operation, the servo motor 813 is controlled to drive the mounting plate 814 to rotate by 90°, thereby synchronously driving the seat 9 to rotate by 90°, so that the seat 9 faces the working operation table body 401, so that the worker controls the working operation table body 401 to realize the drilling operation, and in the rotating process of the mounting plate 814, the sliding action between the ball rod 812 and the mounting plate 814 can ensure the stability of the rotation of the mounting plate 814;

[0032] The horizontal detection sensor 815 is used to detect the inclination state of the seat 9, and the controller controls the adjusting motor 802 to work, drives the movable block 804 to move, drives the movable table 806 to move up and down through the connecting rod 805, adjusts the height of the seat 9, and rotates the rotating shaft 809 through the meshing of the gear 816 and the toothed rack 817, adjusts the angle of the seat 9, realizes the horizontal adjustment of the seat 9, and synchronously adjusts the distance between the seat 9 and the operation platform frame 4, so as to automatically realize the multi-dimensional adjustment of the driver's sitting posture, without the need for workers to continuously provide supporting force to maintain their own posture, thereby fundamentally avoiding physical discomfort caused by long-term maintenance of the posture, and significantly reducing the work burden of the workers;

[0033] During the use of the device, when the whole boring jumbo is in an inclined state, the seat 9 is opposite to the driving operation platform 7 to realize the movement of the boring jumbo, at this time the horizontal detection sensor 815 does not work, when the seat 9 is rotated by 90° to be opposite to the operation platform body 401 to perform drilling operation, at this time the horizontal detection sensor 815 works to realize the inclination angle detection of the seat 9, when it is detected that the seat 9 is in an inclined state (for example, the operation platform frame 4 on one side is low and the cab shell 6 on one side is high), at this time the horizontal detection sensor 815 feeds back a signal to the controller, the controller controls the adjusting motor 802 to start, the adjusting motor 802 drives the threaded rod 803 to rotate in a positive direction, so that the two movable blocks 804 move towards each other under the action of force, and the movable table 806, the supporting rod 810, the circular table 811 and the mounting plate 814 move upward under the action of force, so that the seat 9 moves upward by a distance, and the height adjustment of the seat 9 is automatically realized, when the supporting rod 810 moves upward, the sliding action between the toothed rod 818 and the connecting frame 820 can ensure the normal upward movement of the supporting rod 810;

[0034] When the movable table 806 moves upward under the action of force, the mounting block 808, the rotating shaft 809 and the gear 816 are synchronously driven to move upward, the meshing transmission action between the gear 816 and the toothed rack 817 drives the rotating shaft 809 to rotate clockwise under the action of force, so as to drive the supporting rod 810, the circular table 811 and the mounting plate 814 to rotate clockwise under the action of force, and then the seat 9 rotates under the action of force until the horizontal detection sensor 815 detects that the seat 9 rotates to a horizontal state, so as to realize the horizontal state adjustment of the seat 9, ensure that the center of gravity of the worker coincides with the center of gravity of the seat 9, and protect the stability of the sitting posture of the worker;

[0035] When the seat 9 is rotated to the horizontal state, the distance between the seat 9 and the operation platform support 4 is increased, and during the rotation of the gear 816, the support rod 810, the circular table 811 and the mounting plate 814 are moved to the side of the operation platform support 4 by the meshing transmission between the gear 816 and the convex tooth frame 817, so as to reduce the distance between the seat 9 and the operation platform support 4, so that the worker can perform the drilling operation control, and when the support rod 810 moves horizontally, the mounting block 808 synchronously drives the connecting frame 820 and the convex tooth rod 818 to move, and the stability of the movement of the convex tooth rod 818 is ensured by the sliding action between the convex tooth rod 818 and the cross rod 819, so as to realize the follow-up control of the convex tooth rod 818 and the gear 816, and ensure the normal operation of the device;

[0036] In summary, when the heading drill rig is inclined with the side of the operation platform support 4 being low and the side of the cab shell 6 being high, the horizontal angle of the seat 9 can be adjusted by the action of the control mechanism 8, and during the angle adjustment, the height of the seat 9 is increased synchronously and the distance between the seat 9 and the operation platform support 4 is reduced synchronously, so as to realize the normal operation, and vice versa, when the heading drill rig is inclined with the side of the operation platform support 4 being high and the side of the cab shell 6 being low, the horizontal angle of the seat 9 can be adjusted by the action of the control mechanism 8 (i.e. the reverse rotation of the threaded rod 803 driven by the adjusting motor 802), so as to realize the horizontal angle adjustment of the seat 9, and during the angle adjustment, the height of the seat 9 is reduced synchronously and the distance between the seat 9 and the operation platform support 4 is increased synchronously, so as to realize the automatic adaptive adjustment and ensure the stability of the sitting posture of the worker, without the worker continuously providing support force to maintain his own posture, thereby avoiding physical discomfort caused by long-term maintenance of the posture and significantly reducing the work burden of the worker.
