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 high-efficiency long helical drilling machine for soil removal, which comprises a machine body, on which a column is installed, on which a winding roller is rotatably connected, on which a motor 1 for driving the winding roller to rotate is fixedly connected, and the winding roller The upper winding is fixedly connected with a steel cable one, and the end of the steel cable one away from the winding roller goes around the upper end of the column and is fixedly connected with a power head. The power head slides along the length of the column and is connected to the column. The drill pipe installed at the bottom is spirally fixedly connected with a screw blade, the power head is equipped with a motor 2 for driving the drill pipe to rotate, the winding roller is wound and fixedly connected with a steel cable 2, and the column is rotatably connected with a guide wheel The end of the steel cable two away from the winding roller is fixedly connected to the power head, and the winding direction of the steel cable one and the second steel cable is opposite. The invention 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 screw drilling machine with high efficiency for soil removal. Background technique [0002] At present, long auger drilling machines are required in the process of drilling and piling. [0003] The existing Chinese patent with the authorization announcement number CN203685019U discloses a long auger drilling machine for efficient soil removal, which includes a vertically arranged mast, a power head and a soil unloading device that are guided up and down above, and the power head is driven below the power head. A drill pipe is connected, and the soil unloading device includes a mounting frame arranged at intervals below the power head, a soil unloading claw rotatably assembled on the mounting frame, and a motor fixed on the mounting frame. The rod includes a telescopic drill rod connected with the power head drive and an auger rod flanged on the lower end joint...
