Problems solved by technology

[0004] The above-mentioned prior art scheme has the following defects: the downward drilling force of the power head and the drilling rod is provided by the deadweight of the power head and the drilling rod, and the drilling force is limited. If it is not enough to overcome the resistance from the soil layer, it will cause the power head to idle and not continue to drill down, which will affect the work efficiency. If the drilling force is increased by increasing the weight of the power head and the drill pipe, it will damage the machine. Higher frame strength requirements increase manufacturing difficulty and production costs

Abstract

The invention relates to a long spiral drilling machine for efficient soil clearing. The long spiral drilling machine comprises a machine body, a stand column is installed on the machine body, a winding roller is rotatably connected to the machine body, a first motor for driving the winding roller to rotate is fixedly connected to the machine body, a first steel cable is fixedly connected to the winding roller in a winding manner, the end, far away from the winding roller, of the first steel cable passes around the upper end of the stand column and is fixedly connected with a power head, and the power head is in sliding connection with the stand column along the length direction of the stand column, the power head is rotatably connected with a drill rod which is vertically arranged downwards, a thread spiral blade is fixedly and spirally connected to the drill rod, the power head is provided with a second motor which is used for driving the drill rod to rotate, the winding roller is wound and fixedly connected with a second steel cable, the stand column is rotatably connected with a guide wheel, the end, far away from the winding roller, of the second steel cable is fixedly connected to the power head, and the winding directions of the first steel cable and the second steel cable are opposite. The long spiral drilling machine has the effect of improving the drilling force of the drill rod to a certain extent.

Description

technical field [0001] The invention relates to the technical field of drilling and piling, in particular to a long auger drilling machine for efficient soil removal. Background technique [0002] All need to use long auger drilling machine in the drilling piling process at present. [0003] The existing authorization announcement number is that the Chinese patent of CN203685019U discloses a kind of high-efficiency soil clearing long auger drilling machine, which includes a vertically arranged mast and a power head and a soil unloading device that are guided up and down, and the power head is driven below the power head. The drill pipe is connected, and the soil unloading device includes a mounting frame arranged at intervals under the power head, a soil unloading claw rotatably assembled on the mounting frame, and a motor fixed on the mounting frame, and the motor is connected to the soil unloading claw in transmission. The rod includes a telescopic drill pipe connected to...
