The utility model provides a soil drilling equipment, including boring soil handle 1, boring soil pole 2, enlarger 3, drill bit 4, bulldozing handle 5, bulldozing pole 6, bulldozing board 7, stand pipe 8, support base 9, bolt 10, stabilizer blade 11, ground spear 12, guide member 13. Adopt threaded connection between brill native pole 2 and enlarger 3, the drill bit 4, brill native pole 2 and the rigid connection of brill native handle 1, the inside hollow structure that is of brill native pole 2, bull stick 6 can be in the inside activity from top to bottom of brill native pole 2, adopts threaded connection between bull stick 6 and the bull plate 7, adopts threaded connection between stand pipe 8 and the support base 9, and it is articulated through bolt 10 between support base 9 and the stabilizer blade 11.

The working principle of the specific embodiment is as follows: the supporting base 9 is hinged with the feet 11 through bolts 10 and is placed on the ground. The guide tube 8 is screwed to the support base 9. Due to the hinge connection between the leg 11 and the support base 9, the leg 11 can rotate in a plane perpendicular to the axis with the line of the bolt 10 as the axis. Meanwhile, a plane can be determined by the three points, and the guide tube 8 can be adjusted to be in a vertical state by adjusting the support legs 11. And the ground spear 12 is inserted to fix the whole guide part, so that the displacement is avoided during soil drilling.

The guide component 13 is sleeved on the soil drilling rod 2, the soil drilling rod 2 is connected with the drill bit 4 through threads, the soil pushing rod 6 penetrates through a soil pushing rod reserved hole 1-1 in the center of the soil drilling handle 1, and the soil pushing plate 7 is connected with the soil pushing rod 6 through threads.

The drill bit 4 is inserted into the guide pipe 8, the lower end of the guide member 13 is inserted into the guide pipe 8, and the upper surface of the guide member 13 is overlapped with the zero scale position of the scale mark 2-1 on the earth drilling rod 2 when the top of the drill bit 4 is contacted with the ground. The soil drilling handle 1 is used for rotating clockwise and downwards to apply pressure, the drill bit 4 is driven by the soil drilling rod 2 to rotate and descend to take soil, and meanwhile the scale shown on the upper surface of the guide member 13 is the current soil penetration depth of the top of the drill bit 4. Because the outer surface of the guide member 13 is tightly attached to the inner surface of the guide pipe 8, the inner surface of the guide member 13 is tightly attached to the outer surface of the soil drilling rod 2, and the soil drilling rod 2 and the guide pipe 8 are coaxial, the soil drilling rod 2 is in a vertical state, the force application direction during soil drilling is limited, and the verticality of the drilling direction is ensured.

After the soil drilling is finished, soil in the cavity of the drill bit 4 is pushed out by pressing the bulldozing handle 5. The diameter of the anti-pinch rod 6-1 above the bulldozing rod 6 is slightly larger than that of the bulldozing rod preformed hole 1-1, when the bulldozing handle 5 is pushed to the end, a distance of 5 centimeters is reserved between the soil drilling handle 1 and the bulldozing handle 5, and fingers are prevented from being pinched.

And repeating the operation of drilling soil and pushing soil, detaching the drill bit 4 when the drill reaches the target depth, connecting the reamer 3 with the soil drilling rod 2 through threads, then applying pressure downwards by using the soil drilling handle 1, and vertically moving the annular flat cutting edge of the reamer 3 downwards under the action of the pressure, wherein the redundant soil on the inner wall of the hole can be cut off as the sectional area of the reamer 3 is slightly larger than that of the drill bit 4 and the cutting edge of the reamer 3 is an annular flat opening, and finally obtaining the hole with a smooth, vertical and determined depth inner wall.
