[0022] The spiral drill rod 2 is a rod body with a spiral material discharge groove in the prior art; during the drilling of the drill bit 3 into the ground, the soil on the drilling path is spirally discharged to the ground through the spiral material discharge groove on the spiral drill rod 2, and in order to avoid the accumulation of the discharged soil at the pile hole, two soil sweeping mechanisms are further arranged on the chassis 1, the two soil sweeping mechanisms are located on both sides of the drilling end of the spiral drill rod 2, and the two soil sweeping mechanisms are used to sweep away the discharged soil near the pile hole in a rotating manner during the drilling of the pile hole.

[0023] Specifically, the two soil sweeping mechanisms are the same in structure and comprise a rotating shaft 8 rotatably arranged on the chassis 1, one end of the rotating shaft 8 is connected with a rotating shaft driving element 17, a sleeve 9 is sleeved on the rotating shaft 8, and a soil sweeping plate 10 is arranged on the sleeve 9; the rotating shaft driving element 17 drives the rotating shaft 8 to rotate, drives the sleeve 9 to rotate around the axis, and correspondingly drives the soil sweeping plate 10 to rotate; the rotating directions of the two sleeves 9 are opposite, and the rotating directions of the soil sweeping plates 10 on the two sleeves 9 are also opposite and abut against the ground, so as to sweep away the discharged soil at the pile hole.

[0024] The sleeve 9 is a hollow cylindrical structure, and has an annular peripheral plate and two opposite end plates. The sleeve 9 has a cylindrical cavity formed inside, and an axial hole is formed in the end plate to communicate with the cylindrical cavity, so that the rotating shaft 8 can be inserted through the axial hole.
