Frozen soil digging machine

Abstract

The invention discloses a frozen soil digging machine. The frozen soil digging machine is characterized in that the frozen soil digging machine comprises a bottom tray, a door type supporting frame, arotating motor, a soil digging casing pipe and a drill pipe. The bottom tray is a steel tray with the top end being provided with a circular hole, four rolling wheels are installed at the bottom of the bottom tray, the door type supporting frame is arranged on the bottom tray, and a movable handle is installed at the top end of the door type supporting frame; and the rotating motor is installed on the door type supporting frame, a control switch is connected to the rotating motor, a threaded connection rod capable of rotating is arranged at the top end of the rotating motor, and lifting of the rotating motor is controlled through rotation of the threaded connection rod. According to the frozen soil digging machine, the frozen soil digging machine is more efficient and more practical, thestructure is simple, the amount of dug soil is large, frozen soil can further be heated, impact digging is conducted, and the frozen soil under complex terrain conditions can be thoroughly and efficiently dug and removed.

Description

technical field [0001] The invention relates to an earth lifting device for frozen soil, in particular to an earth lifting machine for frozen soil. technical background [0002] The permafrost stratum is a common complex stratum in the process of geotechnical engineering construction. The characteristics of frost heaving and thawing of the permafrost can easily damage the surface buildings. To solve this problem, the current effective and reliable solution is to use the permafrost Carry out excavation, and then backfill the normal soil, so as to fundamentally solve the permafrost hazard; however, due to the complexity of the permafrost coverage and buried depth, the excavation and backfill will not be complete, and a small-scale frozen-thaw cycle will remain , which has laid hidden dangers for the long-term safety of surface buildings. [0003] At present, there are many kinds of emerging earth excavating equipment. For example, the Chinese invention patent CN106592669A dis...

Problems solved by technology

[0002] The permafrost stratum is a common complex stratum in the process of geotechnical engineering construction. The characteristics of frost heaving and thawing of the permafrost can easily damage the surface buildings. To solve this problem, the current effective and reliable solution is to use the permafrost Carry out excavation, and then backfill the normal soil, so as to fundamentally solve the permafrost hazard; however, due to the complexity of the permafrost coverage and buried depth, the excavation and backfill will not be complete, and a small-scale frozen-thaw cycle will remain , laying hidden dangers for the long-term safety of surface structures

[0003] At present, there are many kinds of emerging earth excavating equipment. For example, the Chinese invention patent CN106592669A discloses a frozen soil excavator. impact, but this large machine is difficult to effectively display in a small space; Chinese invention patent CN103255793B discloses a hand-held excavator, this utility model can effectively reduce the labor intensity of workers in the field of manual digging piles, but due to its own characteristics , the excavation speed is low, and the excavation volume is small, which cannot effectively improve the excavation efficiency

[0004] To sum up, the existing large-scale permafrost excavation equipment is difficult to effectively display in the narrow permafrost construction environment, while the traditional small hand-held excavators have low working efficiency, slow permafrost excavation speed, and difficult excavation in permafrost. Open, the present invention overcomes the above deficiencies, and can efficiently and thoroughly excavate permafrost in a narrow construction environment
