In this embodiment, specific: the rotation speed of the auger 7 is slowed down due to the influence of the blocking force, so that the centrifugal arc block 805 moves towards the position of the rotating shaft 801, the centrifugal arc block 805 presses the vertical moving block 901 by using the connecting block 807, the vertical moving block 901 starts to move upwards, the vertical moving block 901 drives the connecting annular plate 902 to move upwards, the limiting plate 808 limits the maximum height of the connecting annular plate 902, the connecting annular plate 902 avoids synchronous rotation with the connecting block 807 by using the rolling balls 903, the ejector rods 904 and the fixing sleeves 905, the connecting annular plate 902 pushes the ejector rods 904 upwards, and the ejector rods 904 drive the arc plates 907 to move upwards.
Then, racks on the surface of the arc-shaped plate 907 drive the gears 909 to rotate, the vertical frame 908 fixes the positions of the gears 909, the gears 909 change the gear position of the knob 910, and intervals between racks on the surface of the arc-shaped plate 907 serve as buffering, so that the rotating speed of the auger 7 cannot be accurately regulated and controlled to a fixed rotating speed, and the intervals serve as buffering, so that the phenomenon that the change of the rotating speed of the auger 7 continuously changes the gear position of the knob 910, and the motor 6 is damaged is avoided.
When the rotation speed of the auger 7 is too high, the centrifugal arc block 805 is far away from the rotation shaft 801, so that the arc plate 907 moves downwards to enable the gear 909 to rotate clockwise, that is, the gear of the knob 910 becomes smaller, so that the rotation speed of the motor 6 becomes slow, the power loss is reduced, idle work is avoided, and when the rotation speed of the auger 7 is too slow, contrary to the above, the auger 7 is prevented from moving downwards when the auger 7 cannot be drilled downwards, and the auger 7 is damaged.
Working principle: the geotechnical engineering sampling device is powered on and started, the electric push rod 3 stretches out downwards to push the lower push plate 4, the motor 6 drives the spiral drill 7 to rotate through the rotating shaft 801 in the process, the spiral drill 7 is arranged above the bottom supporting plate 1, the spiral drill 7 is in contact with the ground, the time period is reserved, the spiral drill 7 is driven to rotate by the motor 6 to reach the preset rotating speed, and then the spiral drill 7 is drilled into the ground to perform geotechnical engineering sampling.
As the auger 7 is driven into the ground, the auger 7 rubs against the ground rock, the friction resistance affects the rotational speed of the auger 7, and the electric push rod 3 pushes the lower push plate 4 downwards at a fixed speed, i.e. the auger 7 is driven into the ground at a fixed speed, the auger 7 is not rotated at a sufficient speed, the auger breaking efficiency is poor, the downward resistance is high, and the lower push plate 4 continues to push the auger 7, which can cause the auger 7 to be damaged and affect the service life.
The auger 7 is affected by rock-soil friction resistance, the rotating speed of the auger 7 is reduced, so that the rotating speed of the circular bottom plate 802 is insufficient, the circular bottom plate 802 drives the connecting tube 803 to rotate, so that the guide rod 804 rotates in a following way, the centrifugal arc block 805 on the surface of the guide rod 804 is subjected to the largest rotating centrifugal force when the auger 7 rotates normally, the centrifugal arc block 805 is far away from the rotating shaft 801, meanwhile, the centrifugal arc block 805 stretches the connecting spring 806, at the moment, the centrifugal force borne by the centrifugal arc block 805 is reduced, the centrifugal force borne by the connecting spring 806 pulls the centrifugal arc block 805 to the position of the rotating shaft 801, the pulling force of the connecting spring 806 is the same as the centrifugal force borne by the centrifugal arc block 805, the distance between the centrifugal arc block 805 and the rotating shaft 801 is shorter than that at the normal rotating speed, the auger 7 rubs with rock-soil, the rotating centrifugal force of the auger 7 changes, resistance generated by the underground rock-soil components is judged, and the rotating speed is adjusted by the adjusting component 9.
The rotation speed of the auger 7 is slowed down due to the influence of the blocking force, so that the centrifugal arc block 805 moves towards the position of the rotating shaft 801, the centrifugal arc block 805 presses the vertical moving block 901 by using the connecting block 807, the vertical moving block 901 starts to move upwards, the vertical moving block 901 drives the connecting annular plate 902 to move upwards, the limiting plate 808 limits the maximum height of the connecting annular plate 902, the connecting annular plate 902 avoids synchronous rotation with the connecting block 807 by using the rolling balls 903, the ejector rods 904 and the fixing sleeves 905, the connecting annular plate 902 pushes the ejector rods 904 upwards, and the ejector rods 904 drive the arc plates 907 to move upwards.
Then, racks on the surface of the arc-shaped plate 907 drive the gears 909 to rotate, the vertical frame 908 fixes the positions of the gears 909, the gears 909 change the gear position of the knob 910, and intervals between racks on the surface of the arc-shaped plate 907 serve as buffering, so that the rotating speed of the auger 7 cannot be accurately regulated and controlled to a fixed rotating speed, and the intervals serve as buffering, so that the phenomenon that the change of the rotating speed of the auger 7 continuously changes the gear position of the knob 910, and the motor 6 is damaged is avoided.
When the rotation speed of the auger 7 is too high, the centrifugal arc block 805 is far away from the rotation shaft 801, so that the arc plate 907 moves downwards to enable the gear 909 to rotate clockwise, that is, the gear of the knob 910 becomes smaller, so that the rotation speed of the motor 6 becomes slow, the power loss is reduced, idle work is avoided, and when the rotation speed of the auger 7 is too slow, contrary to the above, the auger 7 is prevented from moving downwards when the auger 7 cannot be drilled downwards, and the auger 7 is damaged.
The whole working flow of the application is just the above, and the step is repeated when the application is used next time.
