As shown in fig. 5, due to the gradient effect of the upper inclined plane 452 and the free state, the cylinder 48 is at the position of the upper inclined plane 453 in fig. 3, so that the cylinder 48 cannot form a circulation return to the initial position (fig. 3), the situation that the shovel plate 6 is reset in advance, and the dregs in the drill cylinder 35 fall into the collapse pit 10 is avoided, the push rod 5 is abutted against the push plate 73 by the further lifting of the sliding block 32, the push plate 73 is pushed upwards due to the guiding effect of the inclined rod 7, the push plate 73 forms the effect of horizontal movement relative to the shovel plate 6, the dregs are conveniently pushed to the periphery of the outline of the collapse pit 10, and the dregs cannot reenter the collapse pit 10, so that the cleaning is facilitated; on the other hand, the pushing plate 73 also generates a downward force on the pushing rod 5, so that the cylinder 48 on the pushing rod 5 moves further downwards until the cylinder 48 leaves the upper inclined surface 452, and the cylinder 48 returns to the position of the middle bottom inclined surface 453 in fig. 3 under the rebound action of the second spring 47, thereby forming a cycle and facilitating the slag discharge from drilling holes to drilling holes.
The specific working procedure of the invention is as follows:
As shown in fig. 3, the free state of the invention is shown, the state enters the pit 10, the shovel 6 firstly contacts the bottom of the pit 10, the gradually square rod 42 is contracted towards the inside of the sleeve 41, the drill cylinder 35 rotates to cut, the bottom surface of the cylindrical drill cylinder 35 is provided with a circle of cutting teeth, the annular ring is cut in the pit 10, the dregs enter the drill cylinder 35, and the state of fig. 4 is finally formed along with the continuous descending of the drill cylinder 35;
During the change of state from the state of fig. 3 to the state of fig. 4, the cylinder 48 is moved to the position of fig. 4 under the influence of the structure of the limiting plate 45.
When the cutting and lifting of the edge of the pit 10 are completed, in the advanced height lifting, the square rod 42 and the shovel plate 6 are pressed by the first spring 43 to keep the height unchanged at the bottom surface of the pit 10, only the sleeve 41 and the drill barrel 35 are lifted independently, at this time, the cylinder 48 continuously slides downwards along the upper inclined surface 452 under the guidance of the upper inclined surface 452 of the limiting plate 45, so that the push rod 5 and the shovel plate 6 are transversely inserted into the bottom of the lifted drill barrel 35, and finally, the first spring 43 is fully stretched (the acting force of the first spring 43 is far greater than that of the second spring 47 and is the dominant acting force) because the lowest end of the upper inclined surface 452 is lower than the initial contact point of the cylinder 48 with the bottom inclined surface 453 in fig. 3, and the cylinder 48 cannot be fully pushed away from the upper inclined surface 452, so that only the state that the shovel plate 6 is inserted into the bottom of the drill barrel 35 can be kept, and finally, and the pit 10 is left together.
After keeping the state of fig. 5 out of the pit 10, the push rod 5 and the shovel 6 still need to move downwards by abutting the push plate 73, so that the cylinder 48 is completely separated from the lower end of the upper inclined surface 452 of the limiting plate 45, and is restored to the state of fig. 3 under the action of the second spring 47.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
