Description

Technical Field

[0001] The utility model relates to the technical field of spiral drill rods, in particular to a special spiral drill rod installed on a pile driver to provide a drilling function. Background Art

[0002] The auger rod is a commonly used drill rod in the field of pile construction. The existing auger rod includes an intermediate rod body and spiral blades arranged on the periphery of the intermediate rod body. The spiral blades are structures of equal diameter and equal wall thickness. In the pile construction operation, the auger rod is driven by the power head of the drilling rig to spirally drill. During the drilling process, the drilling debris generated by drilling is transported to the surface along the upper surface of the spiral blades.

[0003] However, the bottom of the existing spiral drill rod is usually a cone-shaped drill bit, which is more convenient when drilling in areas with soft soil. However, when drilling in land with a lot of gravel, the cone-shaped drill bit is greatly worn due to the squeezing of the drill bit by the ground beside the drill bit and the friction of the gravel on the drill bit. Therefore, the drill bit needs to be replaced during the drilling process, resulting in excessively high drilling costs and affecting the drilling efficiency. Summary of the invention

[0004] The utility model aims to provide a special spiral drill rod installed on a pile driver to provide a drilling function, so as to solve the problem proposed in the above-mentioned background technology that when drilling on land with a lot of gravel, the drill bit is squeezed by the land beside the drill bit and the drill bit is rubbed by the gravel, resulting in greater wear on the conical drill bit, so that the drill bit needs to be replaced during the drilling process, resulting in excessively high drilling costs and affecting the drilling efficiency.

[0009] Preferably, a fixed block is fixedly connected to the outer surface of the lower end of the auger rod 2, and the bolt 1 is fixedly connected to the fixed plate by rotating the fixed block. The stirring column 1 and the stirring column 2 are both plate-shaped, and one end of the stirring column 1 and the stirring column 2 are both in an unsealed state.

[0013] When the connecting rod rotates, the auger rod 1, the auger rod 2 and the drill bit are driven to rotate synchronously, so that the drill bit drills into the ground. At the same time, the fixed plate, the stirring column 1 and the stirring column 2 rotate synchronously, so that the stirring column 2 can crush the ground next to the drill bit, thereby reducing the extrusion force on the drill bit. At the same time, the rotation of the drill bit also drives the barbs to rotate, so that the barbs make it easier for the drill bit to drill downward into the ground, thereby cooperating with the rotation of the stirring column 1 and the stirring column 2 to reduce the wear of the drill bit. As the auger rod 1 and the auger rod 2 rotate, the spiral blades rotate synchronously, thereby transporting the crushed soil to the surface through the spiral blades.

[0014] By rotating the bolt two, the auger rod one and the auger rod two are fixedly connected, so that the auger rod one and the auger rod two are convenient to carry. At the same time, when the auger rod one or the auger rod two is damaged, it can be quickly replaced without the need to replace it as a whole, thereby reducing the drilling cost.
