Then the output shaft of the motor 15 continues to rotate counterclockwise to drive the U-shaped rotating plate 16 to move from the state shown in fig. 8 to the state shown in fig. 10, in this process, since the driving gear 22 in fig. 8 is already in the engaged state with the second driven gear 26, then, as the U-shaped rotating plate 16 continues to rotate counterclockwise, and the elastic force provided by the spring 18 for the sliding block 17 makes the toothed plate 19 move vertically upward while maintaining the state shown in fig. 8 for the displacement block 20, the driving gear 22 and the second driven gear 26 are driven to rotate through the engaged relation between the toothed plate 19 and the driving gear 22, the second driven gear 26 rotates, and the central shaft 5 is driven to rotate through the transmission of the worm 23 and the worm wheel 24 corresponding to the positions thereof, the conical gear 8 rotates through the rotation of the central shaft 5, in this process, because of the worm wheel 24 connected with the sleeve 6, the worm 23 has the self-locking property of unidirectional transmission, sleeve 6, lug 7 and back shaft 9 can not all rotate by oneself, and then at a conical gear 8 pivoted in-process, will drive two 10 rotations of conical gear, because sleeve 6 can't rotate, and then through the spherical piece 12 and the sliding fit between the mouth 13 in figure 3 again, will make sampler barrel 2 only carry out horizontal reciprocating motion, and then combine figure 7 to show, through the process of the horizontal reciprocal shake of sampler barrel 2, can make the soil in the sampler barrel 2 fall into to store in the container bottle 31 below by feed opening 3 is automatic completely, and this application passes through the horizontal reciprocal shake process of sampler barrel 2, it has soil to avoid remaining in the sampler barrel 2, further improved the accuracy that the different degree of depth detected the little biological diversity of soil.
And the U-shaped rotating plate 16 is driven to move from the state shown in FIG. 10 to the state shown in FIG. 4 by the continuous counterclockwise rotation of the output shaft of the motor 15, and in the process, the displacement block 20 is transversely moved by the rotation of the U-shaped rotating plate 16 until the driving gear 22 is meshed with the driven gear 25 again, and the initial state is automatically switched to the initial state so as to perform sampling at the next depth. Meanwhile, in combination with the states of the sheave mechanisms in fig. 10 and fig. 4, in the process of returning to the state shown in fig. 4 from the movement of fig. 10, the first connecting shaft 28 is driven by the sheave mechanism to rotate, and then the second connecting shaft 29, the rotating shaft 27 and the bearing plate 30 are driven by the pulley transmission part and the bevel gear transmission part to intermittently rotate synchronously, so that the next empty container bottle 31 moves to the position below the feed opening 3, and therefore, the soil sampled at different depths can be stored in sequence.
After sampling, the depth adjusting button on the controller 36 is pressed, so that the push rod part of the electric push rod 34 is contracted, the shell 1 and the sampling tube 2 are controlled to return to the initial positions, then the door plate on the surface of the shell 1 is opened, and each container bottle 31 is taken out and sent to a corresponding detection department for detection.
In addition, in the process of using the container bottle 31 of the present application, attention should be paid to avoid the problem of contamination between samples, so in practical operation, each time a sample in the container bottle 31 is taken, the sampling container bottle 31 in contact with the sample needs to be replaced (sterilized in advance).
