Embodiment

[0016] Such as figure 1 As shown, a rotary excavator soil throwing auxiliary tool includes a terminal 1 and a base 2, and the terminal 1 is a screw rod structure, including a cylindrical rod and a helical piece on the outer surface of the rod, The helical piece spirally extends along the outer surface of the rod to form a hollow channel, and the base 2 is used to fix the end head 1. When in use, use the base 2 to stabilize the end head 1, and use the base 2 to stabilize the end head 1. The hollow channel of the screw rod structure at the end 1 disturbs the soil in the drilled copper of the rotary excavator, thereby reducing the soil throwing time of the rotary excavator and improving the construction efficiency of the rotary excavator.

[0017] Specifically, in the present embodiment, the end 1: cut 1.2m long, the end of the long screw rod drill bit with a diameter of 100mm (the length from the welding point welded to the steel mesh 4 to the top of the end is 1.2 m) m), the r...

Abstract

The invention relates to a rotary drilling rig soil throwing auxiliary tool, which comprises an end and a base, wherein the end has a helical rod structure and comprises a cylinder rod and a helical sheet on the outer surface of the rod; the helical sheet helically extends along the outer surface of the rod to form a hollow channel; the base is used for fixing the end, the end is stabilized by using the base, the helical rod structure of the end is used to disturb soil in the drilling cylinder of the rotary drilling rig, the rotary drilling rig soil throwing time is further reduced and the rotary drilling rig construction efficiency is improved. The rotary drilling rig soil throwing auxiliary tool is composed of the end and the base, the structure is simple, the base is made full use of tostabilize the end, the end disturbs clay in the drilling cylinder of the rotary drilling rig, the rotary drilling rig soil throwing time is reduced, the rotary drilling rig construction efficiency isimproved, the construction progress is quickened, and the effects of reducing cost and increasing efficiency are achieved.

Description

technical field [0001] The invention relates to the field of construction machinery, in particular to an auxiliary tool for throwing soil of a rotary excavator during the construction of a pile foundation project. Background technique [0002] Rotary drilling rig is a construction machine suitable for hole-forming operations in building foundation engineering. It is mainly suitable for the construction of sandy soil, cohesive soil, silty soil and other soil layers, and is widely used in various foundation constructions such as cast-in-place piles, diaphragm walls, and foundation reinforcement. [0003] When the rotary drilling rig performs drilling operations, it is necessary to shake off the soil brought out from the drill bucket. At present, during the soil extraction process using rotary excavators for pile foundation engineering, if loose soil is taken out, the rotary excavator takes about 1 to 2 minutes to remove the soil. It will often increase greatly, generally abo...
