Description

Technical Field

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology to determine the appropriate bearing layer, and then determine the foundation type and calculate the foundation parameters based on the bearing capacity of the foundation of the bearing layer. It is mainly used to find out the quality and quantity of minerals, as well as the technical conditions for mining and utilization, and to provide mineral reserves and geological data for mine construction design.

[0003] However, during geological exploration, as the drill bit continues to go deeper, the moisture in the soil increases, causing the soil's support to deteriorate. In this case, the drilled hole is more likely to collapse. The collapse will not only damage the equipment, but may also cause instability in the geological structure around the hole, thereby affecting the accuracy and safety of the exploration. Therefore, in order to ensure the smooth progress of geological exploration, corresponding technical measures need to be taken, such as using special drill bit materials, increasing the stability of the hole, etc., to reduce the risk of collapse. In response to the above problems, it is urgent to carry out innovative designs based on the original exploration drilling equipment. Utility Model Content

At the same time, with the rotation of the main rotating shaft 1, the toggle rod 804 is driven to rotate, and the ends of the movable columns 803 arranged downward at equal angles on the inner sleeve 7 are periodically pressed against each other, so that the movable columns 803 move into the fixed cylinder 801, and the return spring 802 is compressed. With the rotation of the toggle rod 804, after the movable columns 803 are separated from the compression, the movable columns 803 are pushed outward by the return spring 802 to hit the inner wall of the outer sleeve 6, so that the outer sleeve 6 vibrates, which acts on the hole soil outside the outer sleeve 6, so that it is compacted under the shock, reducing the possibility of collapse;

[0027] Subsequently, as the main shaft 1 rotates, the inclined fan blade disc 306 is driven to rotate, and the desiccant transported by the delivery pipe 4 to the box body 2 is transported to the opening 307. Then, the fan blade tube 5 rotating with the main shaft 1 spreads the desiccant more evenly on the outer wall of the hole soil to absorb soil moisture and further prevent collapse. This is the working principle of the geological exploration drilling anti-collapse device.
