After the sampling is completed, the lifting cylinder 401 drives the sampling mechanism 5 to move upward. After the upward movement, the motor 2 601 is rotated to move the sample storage tube 606 to the lower end of the sampling mechanism 5. The sampled soil is moved to the inside of the sample storage tube 606 by the downward movement of the electric push rod 503.

The soil fault sampling equipment for environmental protection detection according to claim 1 is characterized in that: The detection mechanism (7) comprises a fixing plate (701), the upper end of the fixing plate (701) is fixedly connected to the lower end of the support plate (402), the end of the fixing plate (701) away from the support plate (402) is hinged with a clamping plate (702), the end of the clamping plate (702) away from the fixing plate (701) is fixedly connected with a connecting block (703), the inner wall of the clamping plate (702) clamps a detector (705), the front end of the connecting block (703) is penetrated by a fastener (704), the inside of the detector (705) is provided with a pH detection module, a data storage module, a digital-to-analog conversion module, and a data transmission module, the output end of the detector (705) is electrically connected to an LED display board (706), the lower end of the LED display board (706) is fixedly connected to the right side of the upper end of the support plate (402).

8. The soil fault sampling device for environmental protection detection according to claim 7 is characterized in that: The left side of the upper end of the support plate (402) is fixedly connected to a power storage box (9), and the left side of the front end of the support plate (402) is fixedly connected to a controller (8).

9. A sampling method for soil fault sampling equipment for environmental protection detection, characterized in that: The following steps are involved: Step 1: The movable wheel (103) is arranged to drive the device to move. When the device moves to the upper end of the soil to be tested, the support rod (202) is fixed by the fixing plate (205) and the retaining cone (206), and then the support rod (202) is driven by the hydraulic rod (204) to reinforce and support the movable base (1); Step 2: After the mobile base (1) is fixed, the motor 1 (403) drives the rotating rod (404) to rotate, and the cone head (505) drills the ground during rotation, and then the lifting cylinder (401) drives the support plate (402) to move downward. During the downward movement, the fixed block (304) is connected with the support plate (402) and the slider (302), and the slider (302) slides with the measuring scale tube (301), so that the size of the downward movement of the sampling mechanism (5) can be detected. After moving down to the position where sampling is required, the electric push rod (503) is moved upward. ) drives the stopper (504) to move upward, and the soil is sampled through the sampling tube (502) by the rotation of the motor 1 (403) and the downward movement of the lifting cylinder (401). After the sampling is completed, the lifting cylinder (401) drives the sampling mechanism (5) to move upward. After the upward movement, the motor 2 (601) is rotated to move the sample storage tube (606) to the lower end of the sampling mechanism (5), and then the electric push rod (503) is moved downward to move the sampled soil to the inside of the sample storage tube (606), and then the soil is tested by the pH detection module of the detector (705); Step three, the detected value is converted into the data stored in the data storage module through the digital-to-analog conversion module, and then transmitted to the LED display board (706) for display by the data transmission module. When a set of value detection is completed, the solenoid valve provided at the lower end of the sample storage tube (606) is opened to discharge the soil inside. When outdoors, the equipment can be supplied with power through the battery box (9).
