First, drill pits of different shapes can affect the collection and penetration capacity of rainwater. At the same time, the layout and shape of the drill pit can affect the surface stability and reduce soil erosion. In addition, the size and depth of the drill pit directly affect the development of the root system and determine the growth potential and stability of vegetation.

A control system is provided on the frame 1, and the control system evaluates the soil quality of the mine based on the drilling pressure of each drill pit position obtained by monitoring, so as to accurately determine the soil type, density and hardness, and provide a scientific basis for subsequent soil improvement and vegetation selection.

[0038] In this embodiment, a soil quality detector is provided on one side of the mud storage tank 13, and the soil quality detector is used to perform real-time layered detection of the soil discharged from the drill pit, so as to identify the type, texture, humidity and heavy metal pollution characteristics of the soil layer through comparison of each layered soil through the database, so as to facilitate the guidance of the subsequent soil plastic forming system for the shape specifications required for the secondary shaping of the drill pit, so that the shape of the drill pit can best adapt to the mining geology and enhance the soil remediation effect.

[0039] In this embodiment, the plastic soil forming system 4 includes:

[0040] A sliding sleeve 41 is slidably connected to the outside of the soil taking pipe 31 in the soil drilling mechanism 3, and a plurality of positioning rods 42 are symmetrically distributed on the sliding sleeve 41, and one end of the positioning rod 42 is slidably connected to the bottom plate frame 2;

[0041] The adapter seat 43 is coaxially arranged below the sliding sleeve 41, and the adapter seat 43 is rotatably connected to the sliding sleeve 41;

[0042] The rotating motor 44 is fixed to one side of the sliding sleeve 41 through a side support, and the output end of the rotating motor 44 is connected to the adapter 43 through a toothed chain for transmission;

[0043] The frame arms 45 are circumferentially distributed on the periphery of the adapter 43. The frame arms 45 are provided with earth movers 5. The earth movers 5 can gradually shape the surface of the drilled hole to form a shaping groove under the rotation drive of the adapter.

[0044] In this embodiment, the soil excavator 5 includes a connecting arm 51, one end of which is rotatably connected to the frame arm 45, a telescopic adjustment rod 52 is connected between the connecting arm 51 and the frame arm 45, a main arm 53 is fixed to the connecting arm 51, a tripod 54 is installed at one end of the main arm 53, a soil excavator frame 55 is provided on one side of the main arm 53, the soil excavator frame 55 is rotatably connected to the main arm 53 through the tripod 54, a fine-tuning rod 56 is connected to the main arm 53, one end of the fine-tuning rod 56 is connected to the soil excavator frame 55, and a plow 57 is installed at the end of the soil excavator frame 55.

Shallow pits facilitate the rapid growth of herbs and low vegetation, achieve rapid greening of the surface, and control soil erosion.
