[0032] The utility model provides a coal mine geological engineering test device through improvement, working principle is as follows:

[0033] First, when using the device, first place the device in the work area, then connect the device with the external power supply, which can provide the required power for the device to work.

[0034] Second, when detecting the dust content, the staff controls the guide fan 64 to work through the control panel 7, so that the guide fan 64 drives the external airflow to flow into the detection box 63 through the air guide cover 61 and the air guide pipe 62. At this time, the condensed airflow is input into the condenser pipe 66 through the condenser 65, so that the external airflow contacts the condenser pipe 66, and the moisture in the condenser pipe 66 is adsorbed on the outer surface of the condenser pipe 66, and finally falls into the water collecting tank 67 for collection, which is beneficial to improve the moisture removal effect of the external airflow, avoid the damage of water and the like to the dust detector 68, and then the airflow flows into the dust detector 68 through the connecting pipe for dust detection action, which is beneficial to improve the rapid detection and accurate detection effect of dust;

[0035] Third, when the coal field soil needs to be detected, the staff controls the single-chip microcomputer 12 to execute the soil detection process through the control panel 7, so that the single-chip microcomputer 12 controls the miniature air pump 811 to input high-pressure airflow into the pneumatic telescopic rod 84 through the corrugated pipe 810, so that the piston rod of the pneumatic telescopic rod 84 drives the mounting plate 85 to move downward, and at the same time, the second servo motor 86 is controlled to drive the soil drilling cone cylinder 87 to rotate, so that the soil drilling cone cylinder 87 moves downward and drills the soil. When the soil drilling cone cylinder 87 rotates, the smaller diameter dust particles enter the sampling cavity 881 inside the inclined groove 882, and are collected on the top of the blocking block 886. After the drilling and sampling action is completed, the second servo motor 86 and the soil drilling cone cylinder 87 and other components are driven upward by the pneumatic telescopic rod 84 through the miniature air pump 811 to enter the working box 1. After the mounting plate 85 is reset under the driving of the pneumatic telescopic rod 84, the single-chip microcomputer 12 controls the first servo motor 81 to drive the driving cylinder 82 to rotate, so that the pneumatic telescopic rod 84 and other components are driven to rotate through the fixing frame 83. The soil drilling cone cylinder 87 is driven to displace above the soil detector 9;

[0036] Fourth, at this time, the miniature electric rod 885 completes upward displacement and stays for 5 seconds and then resets downward through the control of the time relay 89, so that the soil powder falls through the inclined groove 882 at the bottom side of the soil drilling cone cylinder 87 to the soil detector 9 for detection. Then, the soil drilling cone cylinder 87 is driven to rotate again above the movable port 11 through the control of the first servo motor 81 and other components, and then the blocking block 886 is driven to displace upward and downward to unload through the miniature electric rod 885. At this time, the piston rod of the miniature electric rod 885 is wiped through the rubber plate 884, which is beneficial to avoid the damage of dust particles to the miniature electric rod 885. Then, the blocking block 886 is reset through the miniature electric rod 885, which is beneficial to improve the sampling work efficiency and detection effect;

[0037] Fifth, when the coalfield water source needs to be detected, the staff controls the single-chip microcomputer 12 to execute the water source detection procedure through the control panel 7, so that the first servo motor 81, the micro air pump 811 and other components drive the soil drilling cone cylinder 87 to enter the water, and the water to be detected flows into the sampling cavity 881 through the inclined chute 882, at this time, the micro electric pole 885 is protected by the protective sleeve 883 and the rubber plate 884 to avoid short circuit of the micro electric pole 885 due to damp, then the first servo motor 81, the micro air pump 811 and other components drive the soil drilling cone cylinder 87 to displace to the top of the water quality detection cylinder 10, and the time relay 89 and the micro electric pole 885 drive the blocking block 886 to perform the discharging action, and then the detector inside the water quality detection cylinder 10 performs the detection action, which is helpful to improve the detection efficiency and the use range of the sampling component through the adjusting action.
