As a further improvement of the present technique, the mechanism housing is mounted on a slideway support.
As a further improvement of the technology, the length of the driving gear is larger than that of the driving ring sleeve.
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 mounted in the motor hole, and then the motor is fixed. The first shaft is fixed by the third fixing plate; the second shaft is fixed by a second fixing plate; the third shaft is fixed by the first fixing plate; the fourth shaft is fixed by a fifth fixing plate; the fifth shaft is fixed by a fourth fixing plate; the shaft sleeve is arranged in the shaft sleeve hole, so that the shaft sleeve is fixed; the driving ring sleeve is nested on the shaft sleeve, so that the driving ring sleeve is relatively fixed and can rotate around the axis of the shaft sleeve to move up and down.
The distance from the axis of the driving shaft to the axis of the first shaft is D1; the length of the first connecting rod is D2; the length of the second connecting rod is D3; the length of the third connecting rod is D4; among D1, D2, D3 and D4, D1 was the shortest and D3 was the longest; d2 is less than D4; and the sum of D1 and D3 is less than or equal to the sum of D2 and D4, so that the first link, the second link and the third link form a variable-speed double-crank mechanism.
The first bevel gear combination, the second bevel gear combination, the third bevel gear combination and the fourth bevel gear combination are installed on corresponding shafts, and the first bevel gear combination can drive the driving gear to rotate through the second shaft, the second bevel gear combination, the third shaft, the third bevel gear combination, the fourth shaft, the fourth bevel gear combination and the fifth shaft.
The first fixing ring is arranged on the driving shaft, and the first connecting rod is arranged on the first fixing ring, so that the motor can drive the first connecting rod to do uniform circular motion around the axis of the driving shaft through the driving shaft and the first fixing ring; the second fixing ring is arranged on the first shaft, and the second fixing ring is provided with a third connecting rod, so that the first connecting rod can drive the first shaft to do circular motion around the axis of the first shaft through the second connecting rod, the third connecting rod and the second fixing ring; since D2 is smaller than D4, the third connecting rod will make variable speed circular motion under the condition that the first connecting rod makes uniform speed circular motion, and the time for the first connecting rod to make a full circle of circular motion is the same as the time for the third connecting rod to make a full circle of circular motion; the third connecting rod drives the first shaft to do variable-speed rotation through the second fixing ring, and the first shaft drives the driving gear to rotate at variable speed through a bevel gear combination, the second shaft, the second bevel gear combination, the third shaft, the third bevel gear combination, the fourth shaft, the fourth bevel gear combination and the fifth shaft.
The length of the driving gear is larger than that of the driving ring sleeve, so that the driving gear is always meshed with the driving ring sleeve in the process that the driving ring sleeve moves up and down.
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 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 and the driving shaft to rotate through the motor shaft, the drill shaft drives the first spiral piece to rotate, and the drill shaft and the driving shaft always rotate at the same speed; according to the working principle of the speed-changing double-crank mechanism, the driving shaft cannot always rotate at the same speed as the first shaft, the rotating speed of the first shaft can be faster than or slower than that of the driving shaft in the rotating process, and the first shaft can also be faster than or slower than the driving shaft when the first shaft drives the driving gear to rotate in a speed-changing manner through a bevel gear combination, a second shaft, a second bevel gear combination, a third shaft, a third bevel gear combination, a fourth shaft, a fourth bevel gear combination and a fifth shaft. Because the drill shaft and the driving shaft always rotate at the same speed, the driving gear can drive the driving ring sleeve to rotate, and therefore the two conditions of being faster than the drill shaft and being slower than the drill shaft occur. When the driving collar is slower than the rotation speed of the drill shaft, the rotation speed of the second helical blade is lower than that of the first helical blade, the second helical blade has an upward helical motion relative to the first helical blade, and the driving collar moves in an upward rotation mode; when the driving collar is faster than the rotation speed of the drill shaft, the rotation speed of the second spiral sheet is higher relative to the rotation speed of the first spiral sheet, the second spiral sheet has a downward spiral motion relative to the first spiral sheet, and the driving collar moves downwards in a rotating mode; the movement of the drive collar and the second flight repeats the process. Because the first spiral sheet and the second spiral sheet always keep repeated up-and-down spiral displacement, the clay is difficult to stick to the first spiral sheet under the continuous dislocation of the first spiral sheet and the second spiral sheet, the condition that the spiral drill is blocked by the clay is further avoided, and the drilling progress of the spiral drill 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 through the variable-speed double-crank mechanism, so that clay is difficult to stick to the first spiral blade, the condition that the auger is blocked by the clay is further avoided, and the drilling progress of the auger is greatly facilitated. The invention has simple structure and better use effect.

The distance D1 between the axis of the drive shaft 38 and the axis of the first shaft 43; the length of the first link 49 is D2; the length of the second link 50 is D3; the length of the third link 51 is D4; among D1, D2, D3 and D4, D1 was the shortest and D3 was the longest; d2 is less than D4; the sum of D1 and D3 is less than or equal to the sum of D2 and D4.
The width of the first spiral sheet 19 is larger than the width of the second spiral sheet 20.
The mechanism shell 1 is mounted on a slideway support.
The length of the driving gear 31 is greater than that of the driving collar 30.
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 mounted in the motor hole 53, and then the motor 2 is fixed. The first shaft 43 is fixed by the third fixing plate 34; the second shaft 44 is fixed by the second fixing plate 33; the third shaft 45 is fixed by the first fixing plate 32; the fourth shaft 46 is fixed by the fifth fixing plate 36; the fifth shaft 47 is fixed by the fourth fixing plate 35; the boss 37 is fitted in the boss hole 55, and then the boss 37 is fixed; the drive collar 30 is nested on the sleeve 37 so that the drive collar 30 is relatively fixed and can move up and down rotationally about the axis of the sleeve 37.
The distance D1 between the axis of the drive shaft 38 and the axis of the first shaft 43; the length of the first link 49 is D2; the length of the second link 50 is D3; the length of the third link 51 is D4; among D1, D2, D3 and D4, D1 was the shortest and D3 was the longest; d2 is less than D4; the sum of D1 and D3 is less than or equal to the sum of D2 and D4, and the first link 49, the second link 50 and the third link 51 form a speed-changing double-crank mechanism.
The first, second, third and fourth sets of conical teeth 39, 40, 41 and 42 are mounted on respective shafts, so that the first set of conical teeth 39 can drive the driving gear 31 to rotate via the second, third, fourth and fifth shafts 44, 40, 45, 41, 46, 42 and 47.
The first fixing ring 48 is mounted on the driving shaft 38, and the first connecting rod 49 is mounted on the first fixing ring 48, so that the motor 2 can drive the first connecting rod 49 to make uniform circular motion around the axis of the driving shaft 38 through the driving shaft 38 and the first fixing ring 48; the second fixing ring 52 is mounted on the first shaft 43, and the third connecting rod 51 is mounted on the second fixing ring 52, so that the first connecting rod 49 can drive the first shaft 43 to make circular motion around its axis through the second connecting rod 50, the third connecting rod 51 and the second fixing ring 52; since D2 is smaller than D4, when the first link 49 makes a uniform circular motion, the third link 51 will make a variable circular motion, and the time for the first link 49 to make a full circle of circular motion is the same as the time for the third link 51 to make a full circle of circular motion; the third connecting rod 51 drives the first shaft 43 to perform variable-speed rotation through the second fixing ring 52, and then the first shaft 43 drives the driving gear 31 to perform variable-speed rotation through a bevel gear combination, the second shaft 44, the second bevel gear combination 40, the third shaft 45, the third bevel gear combination 41, the fourth shaft 46, the fourth bevel gear combination 42 and the fifth shaft 47.
The length of the driving gear 31 is greater than that of the driving ring sleeve 30, so that the driving gear 31 is always engaged with the driving ring sleeve 30 during the up-and-down movement of the driving ring sleeve 30.
One end of the connecting block 18 is mounted on the driving ring sleeve 30, 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 30 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 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: after the motor 2 is started, the motor 2 drives the drill shaft 3 and the driving shaft 38 to rotate through the shaft of the motor 2, the drill shaft 3 drives the first spiral piece 19 to rotate, and the drill shaft 3 and the driving shaft 38 always rotate at the same speed; according to the operating principle of the speed-changing double-crank mechanism, the driving shaft 38 cannot always rotate at the same speed as the first shaft 43, the rotating speed of the first shaft 43 can be faster than that of the driving shaft 38 or slower than that of the driving shaft 38 in the rotating process, and then the first shaft 43 drives the driving gear 31 to rotate at a speed-changing speed through a bevel gear combination, the second shaft 44, the second bevel gear combination 40, the third shaft 45, the third bevel gear combination 41, the fourth shaft 46, the fourth bevel gear combination 42 and the fifth shaft 47, and can also be faster than that of the driving shaft 38 or slower than that of the driving shaft 38. Since the drill spindle 3 and the drive spindle 38 are always rotated at the same speed, the drive gear 31 can rotate the drive collar 30, so that both faster and slower than the drill spindle 3 occur. When the driving collar 30 is slower than the drill shaft 3, then the rotation speed of the second helical blade 20 is lower than the rotation speed of the first helical blade 19, then the second helical blade 20 has an upward helical movement relative to the first helical blade 19, and the driving collar 30 moves rotationally upward; when the driving collar 30 is faster than the rotation speed of the drill shaft 3, then the rotation speed of the second helical blade 20 is higher relative to the rotation speed of the first helical blade 19, then the second helical blade 20 will have a downward helical movement relative to the first helical blade 19, and the driving collar 30 moves rotationally downward; the movement of the drive collar 30 and the second spiral piece 20 repeats the above process. Because the first helical blade 19 and the second helical blade 20 always keep repeated up-and-down helical displacement, the clay is difficult to stick to the first helical blade 19 under the continuous dislocation of the first helical blade 19 and the second helical blade 20, thereby avoiding the situation that the auger is blocked by the clay, and being greatly beneficial to the drilling progress of the auger.
In conclusion, the invention has the main beneficial effects that: the invention keeps repeated dislocation movement between the first spiral sheet 19 and the second spiral sheet 20 through the variable-speed double-crank mechanism, so that clay is difficult to stick to the first spiral sheet 19, the condition that the auger is blocked by the clay is further avoided, and the drilling progress of the auger is greatly facilitated. The invention has simple structure and better use effect.
