Soil Layer Detection Drilling Device with Nested Sampling Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soil sampling devices cannot continue to detect and sample downward after being filled with soil, limiting them to sampling at a certain depth, which is insufficient for comprehensive soil analysis, especially for soil pollution control and deep soil composition analysis.
Innovation Solution
A soil layer detection drilling device is designed with a drilling cylinder, drive wheels, and a soil-sampling assembly that includes a sliding disk, conical head, screw rod, and soil-sampling members, allowing for continuous multi-point sampling of deep soil layers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a traditional soil sampling device is used, then sampling at a certain depth is achieved, but continuous multi-point sampling of deep soil layers cannot be performed
Solution Approach 1:
The soil sampling device employs a nested structure where the sampling assembly is housed within a drilling cylinder, which itself is contained within an outer casing. The sampling cylinder fits inside the drilling cylinder, allowing compact storage and easy deployment of multiple sampling components within a single device unit, enabling continuous multi-point sampling without requiring multiple separate devices
Solution Approach 2:
The device is divided into distinct functional segments: a drilling cylinder for borehole creation, a sampling assembly with multiple sampling cylinders for multi-point collection, and a lifting mechanism. This segmentation allows each component to perform its specific function efficiently while working together to achieve continuous deep soil sampling at multiple depths
2Measurement precision
If soil sampling is performed at multiple deep points, then comprehensive soil composition analysis is enabled, but the device must be able to drill and sample continuously downward
Solution Approach 1:
The device incorporates a movable sampling cylinder that can be dynamically positioned at different depths within the drilling cylinder. The sampling assembly can move upward and downward along the drilling cylinder axis, allowing continuous sampling at multiple depth points without requiring device removal or repositioning. The lifting mechanism enables dynamic adjustment of the sampling cylinder position to collect samples from various soil layers sequentially
Solution Approach 2:
The drilling cylinder creates the borehole in advance, preparing the path for subsequent sampling operations. The sampling cylinder is pre-positioned within the drilling cylinder, ready to be deployed to collect samples at predetermined depth intervals. This preliminary drilling action enables efficient continuous sampling without repeated drilling operations

Function Achieved in This Case
The device enables continuous drilling and sampling of deep soil layers, facilitating comprehensive analysis of soil composition and pollution, and allowing for more accurate decision-making in soil management and pollution control.
Implementation Method 1
a screw rod is connected between the sliding disk and the conical head by a bearing, and an upper end of the screw rod penetrates above the sliding disk and is matingly connected with an output shaft of the drive motor by a coupling; and a soil-sampling member and a jacking member are matingly mounted on the screw rod

AI summary
A soil layer detection drilling device includes a drilling cylinder, and a soil-sampling assembly is provided inside the drilling cylinder. When the soil is drilled, equipment is in a vertical state, a controller is turned on to control a rotary motor to rotate, and the drilling cylinder is driven to drill the soil with the cooperation of drive wheels and a drive belt. Four slide blocks are evenly distributed around an outer circumference of a sliding disk and are matingly connected with slide grooves provided on an inner wall of the drilling cylinder, so when the drilling cylinder rotates, the soil-sampling assembly also rotates. A conical head first in contact with the ground starts to drill the ground, then the drilling cylinder gradually drills into a soil layer, and the drilling cylinder is idled as the drilling cylinder arrives at a certain depth, to clear soil on auger blades.
