Drilling device for soil detection

Abstract

The invention relates to the field of soil detection tools, and particularly discloses a drilling device for soil detection. The drilling device consists of a main machine and a drilling tool, wherein the drilling tool comprises a drilling rod, a spiral piece is arranged on the drilling rod, and teeth are evenly distributed on the periphery of the spiral piece; the main machine is internally provided with a plurality of rotary frames, a main shaft, a transmission shaft and a driving shaft which are sequentially in transmission connection, each rotary frame is provided with a plurality of roller shafts, the roller shafts are sleeved with stirring rollers, the driving shaft is provided with a pedal, after the drilling tool is combined with the main machine, the pedal can be treaded to drive the rotary frames to rotate, when the rotary frames rotate, the stirring rollers on the rotary frames circularly stir the teeth to jointly drive the drill rod to rotate, and then the drill rod is driven to drill downwards. The drilling device for soil detection is scientific and reasonable in structure, high in utilization rate of mechanical parts, small in energy loss, flexible and convenient to use, efficient and labor-saving in operation, large in drilling depth range and high in practicability, and has wide application prospects in soil detection.

Description

technical field [0001] The invention relates to a soil detection tool, in particular to a drilling device commonly used in the soil detection and sampling process. Background technique [0002] In the practice of soil environment monitoring and agricultural planting production, it is often necessary to test and analyze the soil at a specific depth to understand the soil pollution degree or composition parameters of the soil. At this time, it is usually necessary to use a drilling device to drill holes in the soil , to place a soil sensor or to sample soil at a specific depth. At present, the commonly used drilling devices for soil testing mostly adopt the hand-held design, which is composed of a drill pipe with helical fins and a main engine with power. Since the main engine is equipped with a motor or a fuel engine, the whole equipment is relatively heavy and not light enough to be used conveniently. , poor portability, although the motor or engine is used as the power sou...

Problems solved by technology

[0003] First, before the drilling operation starts, the equipment needs to be erected manually on the ground, and the relatively heavy main engine must be lifted to a high position. During the drilling operation, the main engine needs to be manually supported. After the drilling is completed, the entire equipment needs to be lifted. The entire operation process is relatively laborious and often cannot be operated by one person to remove the drill pipe from the hole.

[0004] Second, the direction of the drill pipe is usually controlled by the operator holding the main engine by hand. It is difficult to ensure that the drilling direction is vertical, which often affects the normal operation of subsequent operations.

[0005] Its three, the existing soil detection drilling device is based on its hand-held structural design characteristics, and a single drill rod should not be too long, otherwise it cannot be used hand-held. The rods are fixedly connected in turn, and the connection operation between the drill rod and the drill rod, and between the drill rod and the main engine is relatively troublesome
