4. A soil collection device for soil microorganism detection according to claim 3, characterized in that: Two partitions (7) are symmetrically inserted into the interior of the housing (6), a bottom plate (18) is installed at the bottom of the fixing frame (1), and circular holes for inserting fixing parts are opened at both ends of the bottom plate (18).

5. A soil collection device for soil microorganism detection according to claim 4, characterized in that: A rubber protrusion (24) is provided on the outer wall of one side of the first collecting box (17) close to the fixing frame (1), and a wavy contact portion (25) is provided on the fixing frame (1) close to the rubber protrusion (24). A baffle is also installed on the top of the first collecting box (17).

6. A soil collection method for soil microorganism detection, characterized in that: The method is applied to the soil collecting device of claim 5, and the collecting method further comprises the following steps: Step 1: After the fixing frame (1) is moved to the area where the soil is to be collected, the circular holes at both ends of the fixing member bottom plate (18) are used to fix the position of the fixing frame (1), and the first motor (4) and the second motor (5) are respectively started. The first motor (4) can drive the movable plate (3) and the lifting mechanism at the bottom thereof to move downward together, so that the lifting blade (10) of the lifting mechanism drills into the soil. The second motor (5) can drive the lifting blade (10) to rotate and transport the soil upward into the housing (6); Step 2: Depending on the type of soil to be collected, one of the two partitions (7) can be removed. If it is necessary to collect soil that is relatively hard and contains a large number of stones, the partition (7) close to the first collecting mechanism can be removed, so that the lifting blade (10) can transport the soil to the first filter plate (15). The first filter plate (15) can filter the stones in the soil and then naturally fall downward into the crushing box (11) for fine processing. After the crushing box (11) completes the processing, it is discharged to the first collection box (17) through the connecting pipe (23) for collection; Step 3: If it is necessary to collect soft soil containing water, the partition (7) near the second collecting mechanism can be removed, so that the lifting blade (10) can transport the soil to the second filter plate (14). The second filter plate (14) can automatically filter the water in the soil and then slide it down into the second collection box (16) for collection; Step 4: The knocking mechanism is set up so that while the second motor (5) drives the first rotating shaft (9) and the second rotating shaft (37) to rotate, the top end of the second rotating shaft (37) drives the rotating block (21) to rotate through the second gear (19) and the first gear (20) that are meshed with each other, and drives the sliding plate (32) to drive the knocking plate (22) to move up and down to continuously knock the first filter plate (15), thereby accelerating the filtration efficiency of the soil falling on the first filter plate (15), and being able to The rotating frame (27), the connecting rod (28), the knocking block (30) and the third filter plate (29) are driven to perform reciprocating motion up and down. The knocking block (30) that moves up and down can knock the second filter plate (14), thereby accelerating the descending speed of the soil on the top of the second filter plate (14). The soil that falls into the second collecting box (16) will fall on the third filter plate (29). The third filter plate (29) that moves up and down can drive the soil on its top to move up and down, thereby accelerating the discharge of the water contained therein, and facilitating the removal of the soil for testing at a later stage.
