[0020] After collecting the soil sample using the collection tube 10, the inner gear ring 16 is rotated to rotate the gear 14 and the vertical shaft 15, driving the corresponding arc-shaped baffle 12 to rotate around one end thereof, so that the other end of the arc-shaped baffle 12 extends into the cavity of the collection tube 10, blocking the collected soil sample to prevent it from falling, thereby avoiding affecting the acquisition of the soil sample and the detection results of the microorganisms.
[0021] Among them, after using the collection tube 10 to collect soil samples, the collection tube 10 can be lifted up a short distance first, so that the collected soil sample is separated from the soil below, and then the other end of the arc-shaped baffle 12 is driven to extend into the collected soil sample in the cavity of the collection tube 10 to remove excess soil samples and at the same time block the collected soil sample.
[0022] Among them, see Figure 2 The outer surface of the inner gear ring 16 is provided with a plurality of anti-slip grooves 17 spaced along its circumference to facilitate manual rotation of the inner gear ring. The inner gear ring 16 is rotatably connected to the outer wall of the collection tube 10.
[0023] Preferably, the width of the arc-shaped baffle 12 is smaller than the difference between the outer diameter and the inner diameter of the lower annular groove 11 , so that the arc-shaped baffle 12 can be completely located in the lower annular groove 11 without protruding from the inner wall of the collection tube 10 .
[0024] Among them, those skilled in the art can choose to set the size of the arc baffle 12 according to actual application, especially the central angle of the corresponding arc, so that when the other end of the arc baffle 12 extends into the cavity of the collection tube 10, the area that can block the collected soil sample can be increased as much as possible. At the same time, when the arc baffle 12 is located in the lower annular groove 11, the sum of the central angles of the arcs corresponding to multiple arc baffles 12 is less than 360°.
[0025] Preferably, see Figure 2 The arc-shaped baffle 12 is provided with a chamfer 18 so that the other end of the arc-shaped baffle 12 can extend into the soil sample collected in the cavity of the collection tube 10 to remove excess soil sample and at the same time block the collected soil sample.
