9. The soil collecting device for soil microorganism detection according to claim 8, wherein the second collecting mechanism comprises a second collecting box (16) installed at the bottom of the other end of the housing (6), a second filtering plate (14) is installed at the bottom of the other end of the housing (6), a rotating frame (27) is hinged to the top of the moving plate (3), the top of one end of the rotating frame (27) is abutted to the bottom of the sliding plate (32), two connecting rods (28) are hinged to the bottom of the other end of the rotating frame (27), the bottom ends of the two connecting rods (28) extend into the second collecting box (16) and are connected with third filtering plates (29), and a knocking block (30) for knocking the second filtering plate (14) is commonly connected between the two connecting rods (28).

10. A soil collection device and collection method for soil microorganisms detection according to claim 9, wherein the method comprises the soil collection device of claim 9, and the collection method further comprises the steps of:

the method comprises the following steps: after the fixing frame (1) is moved to an area where soil is to be collected, fixing the position of the fixing frame (1) by using circular holes at two ends of a fixing piece bottom plate (18), respectively starting a first motor (4) and a second motor (5), wherein the first motor (4) can drive a movable plate (3) and a lifting mechanism at the bottom of the movable plate to move downwards together, so that lifting blades (10) of the lifting mechanism are drilled into the soil, and the second motor (5) can drive the lifting blades (10) to rotate and convey the soil upwards into a shell (6);

step two: one of the two clapboards (7) can be selectively removed according to the type of soil to be collected, if soil with hard soil quality and containing a large amount of stones needs to be collected, the clapboard (7) close to the first collecting mechanism can be taken out, so that the soil is conveyed to the first filter board (15) by the lifting blade (10), the stones existing in the soil can be filtered by the first filter board (15) and then naturally fall into the crushing box (11) for refining treatment, and the stones are discharged into the first collecting box (17) for collection through the connecting pipe (23) after the treatment of the crushing box (11) is finished;

step three: if soil with soft soil quality and moisture is required to be collected, the partition plate (7) close to the second collecting mechanism can be taken out, so that the lifting blade (10) conveys the soil to the second filter plate (14), and the second filter plate (14) can automatically filter the moisture in the soil and then downwards slide into the second collecting box (16) for collection;

step four: can drive first pivot (9) and second pivot (37) pivoted in second motor (5) through the knocking mechanism who sets up, the top of second pivot (37) drives turning block (21) through intermeshing second gear (19) and first gear (20) and rotates, drive sliding plate (32) drive and strike board (22) reciprocating motion from top to bottom and constantly strike first filter (15), make the filtration efficiency of the soil that falls on first filter (15) accelerate, and can drive swivel mount (27) when sliding plate (32) reciprocate, connecting rod (28), strike piece (30) and third filter (29) together and carry out reciprocating motion from top to bottom, strike piece (30) that reciprocates can strike second filter (14), accelerate the falling speed of second filter (14) top soil, the soil that falls into in second collecting box (16) can fall on third filter (29), and the third filter (29) that reciprocates can drive the soil at its top, the moisture that contains the interior row of being convenient for the later stage of removing the detection of containing soil.
