As a further improvement of the present technology, the width of the first flight is greater than the width of the second flight.
As a further improvement of the present technique, the mechanism housing is mounted on a slideway support.
According to the drilling mechanism, the mechanism shell is arranged on the sliding support, so that the mechanism shell can slide up and down on the sliding support to adapt to drilling under different conditions. The motor is arranged on the mechanism shell through the motor fixing frame, so that the motor is fixed; the driving clamping ring is arranged on the mechanism shell through the fixing plate, so that the driving clamping ring is fixed; the driving disc is arranged in the driving snap ring, so that the driving disc is fixed and can rotate in the driving snap ring under the driving of the driving shaft; the driving ring sleeve is arranged in the fixed ring sleeve, so that the driving ring sleeve is relatively nested and fixed, and the driving ring sleeve can rotate up and down in the fixed ring sleeve.

One end of the spiral spring is arranged on the driving shaft, and the other end of the spiral spring is arranged on the inner circular surface of the driving ring sleeve, so that the driving shaft can drive the driving ring sleeve to rotate through the spiral spring. The two functions of the scroll spring are: on one hand, the spiral spring can play a certain lag transmission, and on the other hand, the spiral spring can realize a certain up-and-down dislocation movement. The function of D being approximately equal to S is: the physical property of the scroll spring can not be damaged when the scroll spring moves up and down in a staggered mode at the limit, and the scroll spring is guaranteed to be still good when being reset.
One end of the connecting block is provided with the driving ring sleeve, the other end of the connecting block is provided with the second spiral sheet, the second spiral sheet is nested on the drill shaft, and then the driving ring sleeve can drive the second spiral sheet to rotate around the drill shaft through the connecting block. The first spiral blade is matched with the second spiral blade, the width of the first spiral blade is larger than that of the second spiral blade, so that when the first spiral blade and the second spiral blade do not perform equal-speed spiral motion, clay drilled by the drill bit is not easy to stick to the first spiral blade, and the blockage of the spiral drill is prevented.
The effect of trigger block spring can make trigger block remove and reset, and the effect that the one end of trigger block has the fillet is, when the shifting block through stir the fillet, can extrude trigger block downwards, trigger block just can remove to trigger block spring direction like this, and during the trigger block was extruded into the sliding tray, and then can avoid trigger block great impact destruction to appear when the shifting block gave trigger block a big power of dialling.
The width of first flight is greater than the width of second flight, and the effect that loosens the soil still can be played to the less width of second flight then, can also reduce the weight on the drill spindle simultaneously, is favorable to the rotatory work of drill spindle.
When the motor is started, the motor drives the drill shaft to rotate through the driving shaft, and the drill shaft drives the first spiral piece to rotate; in addition, the driving shaft drives the driving ring sleeve to rotate through the spiral spring, the spiral spring is compressed to store energy when the driving ring sleeve is driven to rotate by the spiral spring, when the spiral spring is compressed to a certain amount, the torque provided by the spiral spring is larger than the starting torque of the driving ring sleeve, and then the driving shaft drives the driving ring sleeve to rotate through the spiral spring, so that the spiral spring drives the driving ring sleeve to have a lagging process, and the driving ring sleeve drives the second spiral piece through the connecting block to also have a lagging process; during this lag, the rotational speed of the second helical blade will be relatively low with respect to the rotational speed of the first helical blade, and the second helical blade will have an upward helical movement with respect to the first helical blade, the driving collar will move rotationally upward, and the wrap spring will produce an upward tensile displacement; when the driving ring sleeve moves upwards to a certain position, the driving ring sleeve drives the ring sleeve cover to move upwards to a corresponding position, and the trigger block can be in contact fit with the shifting block. In the rotating process of the shifting block, the shifting block can shift the trigger block, and when the shifting block is shifted and matched, the shifting block transmits a large shifting force to the trigger block, at the moment, the trigger block is extruded into the sliding groove under the action of the circular angle of the trigger block, and simultaneously, the shifting block also provides a large rotating force for the ring sleeve cover through the trigger block, so that under the driving of the large rotating force, the rotating speed of the ring sleeve cover can exceed the rotating speed of the driving shaft, and the rotating speed of the ring sleeve cover for driving the ring sleeve can also exceed the rotating speed of the driving shaft, so that the compressed volute spring can release the compression amount of the volute spring at the exceeding speed of the driving ring sleeve; in the process, the ring sleeve cover can drive the second spiral piece to rotate through the driving ring sleeve and the connecting block, and the rotating speed of the second spiral piece exceeds the rotating speed of the first spiral piece driven by the driving shaft and the drill shaft; the second flight will have a downward helical movement relative to the first flight; thus, the ring cover, the driving ring and the second spiral sheet will relatively rotate downwards, and the spiral spring will produce downward displacement. When the driving ring sleeve rotates downwards to move to a certain position, the poking energy provided by the poking block for the driving ring sleeve is consumed, at the moment, the driving shaft drives the driving ring sleeve to rotate through the volute spiral spring again, and in the process that the driving shaft drives the driving ring sleeve to rotate, the volute spiral spring needs to be compressed again, so that the driving shaft drives the driving ring sleeve to rotate through the volute spiral spring, a lagging process is generated, and the driving ring sleeve and the second spiral piece can repeat the process.
In the above-described movement process, the first helical blade and the second helical blade always keep repeated up-and-down helical displacement, so that under the continuous dislocation of the first helical blade and the second helical blade, clay is difficult to stick on the first helical blade, the situation that the auger is blocked by the clay is further avoided, and the drilling progress of the auger is greatly benefited.
Compared with the traditional auger technology, the invention keeps repeated dislocation movement between the first spiral blade and the second spiral blade all the time, so that clay is difficult to stick to the first spiral blade, and further the condition that the auger is blocked by the clay is avoided, thereby greatly benefiting the drilling progress of the auger. The invention has simple structure and better use effect.

The distance between the upper side of the spiral spring 16 and the ring cover 10 is named as S; the distance between the upper and lower sides of the wrap spring 16 is designated as D; d is approximately equal to S.

The mechanism shell 1 is mounted on a slideway support.
In the invention, the mechanism shell 1 is arranged on the sliding bracket, so that the mechanism shell 1 can slide up and down on the sliding bracket to adapt to drilling under different conditions. The motor 2 is arranged on the mechanism shell 1 through a motor fixing frame 9, so that the motor 2 is fixed; the driving snap ring is installed on the mechanism shell 1 through the fixing plate 8, and then the driving snap ring is fixed; the driving disk 5 is installed in the driving snap ring, so that the driving disk 5 is fixed and can rotate in the driving snap ring under the driving of the driving shaft 4; the driving collar 14 is installed in the fixed collar 15, so that the driving collar 14 is relatively nested and fixed and the driving collar 14 can move up and down in the fixed collar 15 in a rotating manner.
One end of the driving shaft 4 is connected with the shaft of the motor 2, and the other end of the driving shaft is provided with the drill shaft 3, so that the motor 2 can drive the drill shaft 3 to rotate through the driving shaft 4; the first helical blade 19 is mounted on the drill shaft 3, so that the drill shaft 3 can bring the first helical blade 19 into a rotational movement.
One end of the spiral spring 16 is mounted on the driving shaft 4 and the other end is mounted on the inner circumferential surface of the driving collar 14, so that the driving shaft 4 can rotate the driving collar 14 via the spiral spring 16. The two functions of the spiral spring 16 are: on one hand, the spiral spring 16 can play a certain lag transmission, and on the other hand, the spiral spring 16 can realize a certain up-and-down staggered movement. The function of D being approximately equal to S is: when the limit of the spiral spring 16 moves up and down in a staggered manner, the physical property of the spiral spring 16 is not damaged, and the spiral spring 16 is ensured to be still good when being reset.
One end of the connecting block 18 is mounted on the driving ring sleeve 14, the other end is mounted with the second spiral sheet 20, and the second spiral sheet 20 is nested on the drill shaft 3, so that the driving ring sleeve 14 can drive the second spiral sheet 20 to rotate around the drill shaft 3 through the connecting block 18. The first flight 19 is fitted with the second flight 20, and the width of the first flight 19 is greater than that of the second flight 20, so that clay drilled by the drill bit 17 will not easily stick to the first flight 19 during unequal auger movement of the first flight 19 and the second flight 20, thereby preventing clogging of the auger.
The effect of trigger block spring 13 can make trigger block 12 remove and reset, and the effect that one end of trigger block 12 has fillet 23 is, when shifting block 6 is through stirring fillet 23, can extrude trigger block 12 downwards, and trigger block 12 just can move to trigger block spring 13 direction like this, and trigger block 12 is extruded into sliding tray 21, and then can avoid trigger block 12 to appear great impact destruction when shifting block 6 gives trigger block 12 a big power of dialling.
The width of the first spiral blade 19 is greater than that of the second spiral blade 20, so that the smaller width of the second spiral blade 20 can still play a role in loosening the soil, and meanwhile, the weight of the drill shaft 3 can be reduced, which is beneficial to the rotation work of the drill shaft 3.
The specific implementation mode is as follows: when the motor 2 is started, the motor 2 drives the drill shaft 3 to rotate through the driving shaft 4, and the drill shaft 3 drives the first spiral piece 19 to rotate; in addition, the driving shaft 4 drives the driving ring sleeve 14 to rotate through the spiral spring 16, because the spiral spring 16 is compressed to store energy when the spiral spring 16 drives the driving ring sleeve 14 to rotate, when the spiral spring 16 is compressed to a certain amount, the torque provided by the spiral spring 16 is larger than the starting torque of the driving ring sleeve 14, and then the driving shaft 4 drives the driving ring sleeve 14 to rotate through the spiral spring 16, the spiral spring 16 drives the driving ring sleeve 14 to have a lagging process, and the driving ring sleeve 14 drives the second spiral piece 20 through the connecting block 18 to also have a lagging process; during this lag, the rotational speed of the second spiral piece 20 is relatively low with respect to the rotational speed of the first spiral piece 19, and the second spiral piece 20 has an upward spiral motion with respect to the first spiral piece 19, so that the driving collar 14 rotates upward and the spiral spring 16 generates an upward tensile displacement; when the driving ring sleeve 14 moves upwards to a certain position, the driving ring sleeve 14 drives the ring sleeve cover 10 to move upwards to a corresponding position, and the triggering block 12 can be in contact fit with the shifting block 6. In the rotating process of the shifting block 6, the shifting block 6 can shift the trigger block 12, and when the shifting block 6 is matched with the trigger block 12, the shifting block 6 provides a large shifting force for being transmitted to the trigger block 12, at the moment, under the action of a round corner 23 of the trigger block 12, the trigger block 12 is extruded into the sliding groove 21, and simultaneously, the shifting block 6 provides a large rotating force for the ring cover 10 through the trigger block 12, so that under the driving of the large rotating force, the rotating speed of the ring cover 10 can exceed the rotating speed of the driving shaft 4, the rotating speed of the ring cover 10 driving the driving ring cover 14 can also exceed the rotating speed of the driving shaft 4, and the compressed spring scroll 16 can release the compression amount of the scroll spring 16 at the exceeding speed of the driving ring cover 14; in the process, the ring cover 10 can drive the second helical blade 20 to rotate through the driving ring 14 and the connecting block 18, and the rotation speed of the second helical blade 20 exceeds the rotation speed of the first helical blade 19 driven by the driving shaft 4 and the drill shaft 3; the second flight 20 will have a downward helical movement relative to the first flight 19; so that the ring cover 10, the drive ring 14 and the second spiral piece 20 will relatively rotate downwards and the spiral spring 16 will be displaced downwards. When the driving ring sleeve 14 rotates downwards to a certain position, the toggle energy provided by the toggle block 6 to the driving ring sleeve 14 is consumed, at this time, the driving shaft 4 drives the driving ring sleeve 14 to rotate through the spiral spring 16 again, and in the process that the driving shaft 4 drives the driving ring sleeve 14 to rotate, the spiral spring 16 needs to be compressed again, so that the driving shaft 4 drives the driving ring sleeve 14 to rotate through the spiral spring 16, a lagging process is generated, and the driving ring sleeve 14 and the second spiral piece 20 can repeat the processes.
During the above described movement, the first flight 19 and the second flight 20 are maintained in repeated up and down helical displacements, so that clay is difficult to stick to the first flight 19 under the continuous misalignment of the first flight 19 and the second flight 20, thereby avoiding the situation that the auger is blocked by clay, and greatly benefiting the drilling progress of the auger.
In conclusion, the invention has the main beneficial effects that: the present invention is advantageous to the drilling progress of the auger by maintaining the repeated offset movement between the first flight 19 and the second flight 20 all the time so that the clay is hardly adhered to the first flight 19, thereby preventing the auger from being clogged with the clay. The invention has simple structure and better use effect.
