Sequence of mechanical actions of the whole device:
when the device starts to work, the device is matched with a lifting bracket for use, certain manual operation can be avoided, the whole device automatically runs, the device is moved to an area needing soil collection, the motor 12 is started, the motor 12 rotates to drive the transmission shaft 46 to rotate clockwise, the ground drilling unit 27 is driven to rotate anticlockwise through the transmission spur gear 38, the ground drilling unit 27 rotates to drive the ground drilling teeth 33 to rotate along the same direction, the ground drilling teeth 33 can vertically and downwards drill the ground in the rotation process by matching with the self gravity of the device, in the process, the ground drilling unit 27 rotates to drive the guide rail shaft sleeve 37 to rotate in the same direction, the transmission guide rail 36 is driven to synchronously rotate, and further, non-target soil which is extruded and excavated by the ground drilling teeth 33 is transmitted into the soil transmission cavity 35 through the soil guide cavity 48, is transmitted upwards through the transmission guide rail 36 and finally discharged out of the device through the soil discharge cavity 24, because the ground drilling unit 27 rotates anticlockwise all the time in the ground drilling process, the baffle sliding cavity 49 rotates synchronously with the ground drilling unit to avoid the soil conveyed upwards, so that the soil is effectively prevented from entering the baffle sliding cavity, and the phenomenon that the soil is accumulated to occupy the inner space of the baffle sliding cavity 49 so that the subsequent work cannot be unfolded is avoided;
when the drilling depth is close to the designated depth, the depth limiting block 40 starts to abut against the ground and is pushed upwards by the counterforce of downward drilling of the integral device, the depth limiting block 40 moves upwards to drive the telescopic rod 41 to move in the same direction, the trigger return spring 44 is influenced by the upward thrust of the telescopic rod 41 to contract upwards, the telescopic rod 41 moves to drive the abutting plate 39 to move upwards so as to drive the transmission spur gear 38 to move upwards to be disengaged from the ring gear 26, at the moment, the ring gear 26 does not rotate any more, so that the drilling unit 27 does not continue to drill downwards, in the process, the gear return spring 68 is influenced by the upward thrust of the transmission spur gear 38 to contract upwards, meanwhile, the telescopic rod 41 moves to drive the magnet 42 to move upwards to be in contact with the electromagnet switch 43, so that the electromagnets 65 and the ring electromagnets 53 are simultaneously started, the electromagnets 65 are started to attract the magnet slide block 67 upwards so as to drive the magnet slide block, the magnet slide block 67 moves upwards to drive the baffle plate 52 to move towards the direction away from the center of the isolation cavity 34 through the pull rope 51 until the isolation cavity 34 is completely exposed and is not shielded by the isolation cavity 34;
on the other hand, the annular electromagnet 53 is started to repel the annular magnet 54 rightwards to push the annular magnet 54 rightwards, the annular magnet 54 rightwards moves to drive the shaft sleeve 55 to move in the same direction to drive the auxiliary transmission bevel gear 56 to move rightwards to be meshed with the auxiliary driven bevel gear 20, in the process, the shaft sleeve reset spring 58 is influenced by the right-hand pulling force of the shaft sleeve 55 to extend rightwards, at the moment, the transmission shaft 46 rotates to drive the main transmission bevel gear 47 to rotate so as to drive the auxiliary transmission shaft 59 to rotate through the main driven bevel gear 13, the auxiliary transmission shaft 59 rotates to drive the shaft sleeve 55 to rotate so as to drive the auxiliary driven bevel gear 20 to rotate through the auxiliary transmission bevel gear 56, the auxiliary driven shaft 20 rotates to drive the auxiliary driven shaft 19 to rotate so as to drive the threaded sleeve 25 to move downwards through the screw 22, so that the threaded sleeve 25 drives the limit trigger slider 30 to move downwards through the fixed 64 penetrating downwardly into the confined layer of soil and loading it into the soil collection chamber 32 to initially complete the soil collection;
when the limiting trigger slide block 30 moves downwards to abut against the trigger slide block 60 and pushes the trigger slide block 60 rightwards, the slide block return spring 63 is influenced by the rightward pushing force of the trigger slide block 60 to be compressed rightwards, at the moment, the soil collection sleeve 31 extends downwards to a depth which just enables the soil collection cavity 32 to be filled with complete soil samples, when the trigger slide block 60 moves rightwards to be in contact with the motor reversing switch 62, the motor 12 reverses and drives the threaded sleeve 25 to move upwards through the reverse rotation of the screw 22, finally, the soil collection sleeve 31 is driven to move upwards to enable the soil samples in the soil collection sleeve to move synchronously with the soil collection sleeve 31, in the process, the slide block return spring 63 pushes the trigger slide block 60 leftwards to enable the trigger slide block 60 to be in an abutting state with the end face of the soil collection sleeve 31 again, when the soil collection sleeve 31 moves upwards to be in a state of being disengaged from the trigger slide block 60, the slide block return spring 63 returns, all trigger mechanisms in the device are powered off, the annular electromagnet 53 does not repel and push the annular magnet 54 any more, and the shaft sleeve return spring 58 restores to a relaxed state to pull the shaft sleeve 55 leftwards so as to drive the auxiliary transmission bevel gear 56 to return leftwards to be disengaged from the auxiliary driven bevel gear 20 and keep a certain distance so as to prevent the subsequent work of taking out a soil sample from being hindered;
after the device stops running, a worker can pull the pull ring 16 upwards to drive the auxiliary driven shaft 19 to move upwards through the circular limiting cover plate 17, finally the soil collection sleeve 31 is driven to move upwards through the limiting trigger slider 30 until the worker pulls the soil collection sleeve out of the device, then the soil collection sleeve 31 can be detached through the limiting trigger slider 30 to carry out subsequent soil sample storage work, then the device can be relatively easily released through a lifting support which can be installed on the device to take out soil samples, and in the process of moving the device upwards, the reset spring 44 and the gear reset spring 68 are triggered; the shaft sleeve return spring 58 and the magnet sliding cavity 66 are both restored to a relaxed state, so that all parts of the device except the threaded sleeve 25 and the fixed clamp 29 are restored, and more convenient use experience is provided for the next soil sampling work;
