Example 2
The present embodiment has the same basic principle as embodiment 1, except that:
as shown in fig. 8, the present embodiment further includes a pull rod 23, a slide 21, and a return spring 24; the sliding seat 21 is arranged in the cavity of the drill rod 2 in a vertically sliding manner, one end of a pull rod 23 is connected with the sliding seat 21, and the other end of the pull rod 23 is connected with the stirring blade 20;
the stirring blade 20 is hinged on the shaft sleeve 10; the return spring 24 is arranged at two ends in the cavity of the drill rod 2 and is respectively connected with the sliding seat 21 and the drill rod 2, the return spring 24 tends to force the sliding seat 21 to slide upwards, and then the stirring blade 20 is forced to be attached to the drill rod 2 through the pull rod 23.
When the drill rod 2 rotates at a low speed, the stirring blade 20 is attached to the drill rod 2 under the action of the elastic force of the return spring 24, so that the resistance of the drill rod 2 during downward drilling is reduced; when the drill rod 2 is drilled into a set depth and impurities such as larger stones need to be filtered and fished, the drill rod 2 is automatically opened by overcoming the elasticity of the return spring 24 through the centrifugal force of the stirring blade 20 by increasing the rotating speed of the drill rod 2; thereby realizing the effects of filtration and salvage.
The drilling rod 2 is provided with a sliding groove 2a communicated with the inside and the outside, the inner side end of the wing rod 22 is connected with the sliding seat 21, and the outer side end of the wing rod 22 extends out of the sliding groove 2a and is hinged with the pull rod 23.
With reference to fig. 9, the chute 2a comprises an axial section 2a1, an intermediate arcuate transition section 2a2 and a circumferential section 2a 3; the axial section 2a1 is arranged in parallel with the drill rod 2 in the axial direction, the circumferential section 2a3 is arranged below the axial section 2a1 and distributed along the circumferential direction of the drill rod 2, and two ends of the middle arc-shaped transition section 2a2 are connected with the axial section 2a1 and the circumferential section 2a3 for smooth transition of the two sections.
When the wing bars 22 slide along the axial segment 2a1, the stirring vanes 20 are deployed or retracted; after the wing rod 22 slides into the circumferential section 2a3 through the middle arc-shaped transition section 2a2, the stirring blade 20 is fully unfolded (arranged at an angle of 80-90 degrees with the drill rod 2) to a set angle; when the wing bars 22 slide along the circumferential section 2a3, the stirring blades 20 remain deployed in a fully deployed state and can rotate circumferentially along the drill rod 2. The circumferential section 2a3 can realize that the stirring blade 20 expands in the circumferential direction to form a complete annular fishing basket, and more importantly, the circumferential section 2a3 serves as a locking structure to prevent the stirring blade 20 from contracting again under the elastic force of the return spring 24, and after the wing rod 22 slides into the circumferential section 2a3, the rotation speed of the drill rod 2 can be adjusted to be low.
More preferably, the stirring blade 20 is inclined in a spiral shape, and an included angle between the stirring blade 20 and a horizontal plane (a cross section perpendicular to the drill rod 2) is 5-10 degrees. The formation of the annular fishing basket cannot be influenced due to a smaller spiral inclination angle; the beneficial effects of the stirring device are that the soil is stirred, the stirring blade 20 is convenient to unfold or fold, and the stirring blade 20 is promoted to unfold or fold quickly and effectively by virtue of the reverse geological thrust. For example, when jamming occurs or for any particular reason the mixing blade 20 needs to be retracted, it is only necessary to reverse the drill rod 2 and the flight 22 gradually moves back from the circumferential section 2a3 to the axial section 2a1 via the intermediate curved transition section 2a2, wherein the reaction force of the geology and the return spring 24 cooperate to force the mixing blade 20 to retract and finally to abut against the drill rod 2 when the drill rod 2 is reversed.
