DETAILED DESCRIPTION

[0023] It should be noted that the terms "first", "second", etc. in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, so that the embodiments of this application described here, based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work should fall within the scope of protection of this application.

[0024] Reference Figure 1-Figure 5 A deep soil sampling mechanism includes a support plate 4, a first motor is fixed to the top of the support plate 4 by bolts, and the bottom of the support plate 4 is rotatably connected to a connecting shaft 1, and one end of the motor output shaft passes through the support plate 4 and is fixed to the connecting shaft 1, and a first spiral piece 3 is fixed to the outside of the connecting shaft 1 by bolts. The rotation of the first motor causes the connecting shaft 1 to drive the first spiral piece 3 to rotate, so that it enters the soil until the first spiral piece 3 is completely submerged. The bottom end of the connecting shaft 1 is fixed to a cover plate 2 through a connecting assembly, and a cavity 14 is opened inside the connecting shaft 1, and a fixing plate 13 is fixed in the cavity 14 by bolts. The top of the fixing plate 13 is fixed to an electric telescopic rod 8 by bolts, and the extended end of the electric telescopic rod 8 passes through the fixing plate 13 and is fixed to a support frame 9 by bolts. The inside of the support frame 9 is fixed to a second motor by bolts, and the bottom of the support frame 9 is fixed to a second collecting box by bolts. 19. The bottom outer wall of the second collecting box 19 is fixed with a connecting pipe 10 by bolts. One end of the second motor output shaft passes through the support frame 9 and is installed with a rotating shaft. The bottom end of the rotating shaft is welded with a drill bit. The outside of the rotating shaft is fixed with a second spiral piece 18 by bolts, and the second spiral piece 18 is located inside the connecting pipe 10. The first collecting box 11 is installed on one side of the second collecting box 19 through a fixing mechanism. The electric telescopic rod 8 is extended to make the support frame 9 drive the components at its bottom to move downward as a whole. At this time, the bottom end of the connecting pipe 10 is flush with the bottom end of the connecting shaft 1. The part of the second spiral piece 18 extending out of the connecting pipe 10 and the drill bit enter deeper into the soil. At the same time, the motor rotates to make the rotating shaft drive the second spiral piece 18 to rotate, so that the soil at the bottom is transported by the second spiral piece 18 into the interior of the first collecting box 11 and the second collecting box 19. After the sampling is completed, the device is removed from the soil.

[0025] In the present invention, it should be noted that the fixing mechanism includes two magnetic blocks 12, and the two magnetic blocks 12 are placed on the outer wall of the top of the second collection box 19 and the first collection box 11. The magnetic block 12 can attract and fix the top of the first collection box 11 and the second collection box 19. The bottom of the magnetic block 12 is fixed with a card block 16 by a bolt. The top of the first collection box 11 and the second collection box 19 are both provided with two card slots 17, and the card block 16 is carded in the card slot 17. Pull the magnetic block 12 upward to separate it from the first collection box 11 and the second collection box 19, and at the same time, the card block 16 moves out of the card slot 17. At this time, the first collection box 11 loses its fixation, which is convenient for the staff to check the contents of the collection box. The sampled soil is taken out, and the connecting component includes a connecting port, which is opened at the bottom of the connecting shaft 1. The top and bottom of the connecting port are fixed with a protrusion 5 by bolts. The top and bottom of the cover plate 2 are threadedly connected with a threaded rod 7, and the threaded rod 7 passes through the cover plate 2 and is inserted into the protrusion 5. The top of the cover plate 2 is opened with a avoidance groove 6, and the avoidance groove 6 is provided with a knob. The threaded rod 7 is fixed to the knob. Turn the knob to separate the threaded rod 7 from the protrusion 5, and then separate the cover plate 2 from the connecting shaft 1. The top inner wall of the second collection box 19 is fixed with a baffle 15 by bolts. The baffle 15 contacts the top inner wall of the first collection box 11, and the baffle 15 can limit the height of the first collection box 11.

[0026] Working principle: When it is necessary to sample the soil, the staff stands above the soil to be sampled, holds the two ends of the support plate 4 to make the drill bit contact the ground, starts the first motor, and the first motor rotates to make the connecting shaft 1 drive the first spiral piece 3 and the drill bit to rotate, so that it enters the soil until the first spiral piece 3 is completely submerged. Then the first motor is turned off, and the second motor is started to start the electric telescopic rod 8. The electric telescopic rod 8 extends to make the support frame 9 drive the bottom parts thereof to move downward as a whole. At this time, the bottom end of the connecting pipe 10 is flush with the bottom end of the connecting shaft 1, and the part of the second spiral piece 18 extending out of the connecting pipe 10 and the drill bit enter the soil. The device is moved deeper into the soil, and at the same time, the motor rotates to drive the rotating shaft to rotate the second spiral piece 18, so that the soil at the bottom is transported by the second spiral piece 18 into the first collecting box 11 and the second collecting box 19. After the sampling is completed, the device is removed from the soil, and then the knob is turned to separate the threaded rod 7 from the protrusion 5, and then the cover plate 2 is separated from the connecting shaft 1, and the magnetic block 12 is pulled upward to separate it from the first collecting box 11 and the second collecting box 19. At the same time, the card block 16 moves out of the card slot 17. At this time, the first collecting box 11 loses its fixation, and the first collecting box 11 can be directly removed to remove the sampled soil inside.
