[0014] The present invention provides a multifunctional drilling machine. It has the following beneficial effects:

[0015] (1) The multifunctional drilling machine uses the crushing device, centrifugal force and its own gravity to continuously penetrate the soil block with the pointed cone and the partition plate, and drills and cuts the junction between the soil block and the spiral plate, so that the base of the soil block becomes loose. Combined with the centrifugal effect, the probability of throwing out the soil block can be increased.

[0016] (2) The multifunctional drilling machine uses a cutting device and a steel wire rope to divide the entire soil block on the spiral plate into five parts. Compared with the entire soil block, the adhesion area of ​​each small soil block to the spiral plate is reduced, and the adhesion force is also reduced. Combined with the drilling and cutting effect of the pointed cone and the partition plate, the small soil blocks are thrown out as much as possible under the action of centrifugal force.

[0017] (3) The multifunctional drilling machine uses a crushing device and a cutting device. The crushing device crushes the base of the soil block to weaken the adhesion of the base of the soil block. The crushing device has a large gravity of its own.

The two pieces cooperate with each other to greatly improve the effect of soil block cleaning.

[0018] (4) The multifunctional drilling machine is equipped with a crushing device and a cutting device. When the pointed cone moves from the lowest point to the highest point, the pointed cone and the partition plate are slowly pulled out of the soil block. The pointed cone and the partition plate return to the circular hole under the action of gravity. The pressure on the wire rope is reduced, and the return spring recovers with the wire rope and produces a slight tremor, which can remove the soil debris adhering to the wire rope. The entire device has a simple structure, automatically drives and cleans the soil blocks adhering to the spiral plate, improves the working efficiency of the drilling machine, protects the drill bit, and increases the working life of the drill bit.
