[0027] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0028] like Figure 1-5As shown, the utility model provides a sampling device for detecting heavy metals in soil, comprising a storage box 2 and a drill bit 1 installed on the storage box 2, wherein the drill bit 1 is a solid conical rotating body structure, and the storage box 2 is a hollow conical rotating body structure. The outer surfaces of the drill bit 1 and the storage box 2 are respectively installed with a first guide blade 12 and a second guide blade 13, and the outer surface of the storage box 2 is provided with a plurality of feed ports 18 and a discharge trough 20, the inner wall of the feed port 18 is hinged with an openable and closable baffle 14, and the inner wall of the discharge trough 20 is hinged with an openable and closable discharge door 24, the interior of the storage box 2 is installed with a stretching mechanism 11 for controlling the opening and closing of the baffle 14, and the top of the storage box 2 is installed with a sleeve rod 3, and the sleeve rod 3 is installed with an operating panel 5.

[0029] Scale lines 4 are provided on the outer surface of the sleeve rod 3 .

[0030] Sampling blades 15 adapted to the material inlet 18 are evenly mounted on the outer surface of the material storage box 2 .

[0031] The sampling blade 15 is arc-shaped, and the opening direction of the sampling blade is opposite to the thread direction of the first guide land 12 and the second guide land 13 .

[0032] The top of the sleeve rod 3 is slidably connected to a connecting rod 7 that passes through the top of the sleeve rod 3. A fixed sleeve 8 is fixed to the connecting rod 7. The outer surface of the fixed sleeve 8 is fixed to a gear rod 9. The inner wall of the sleeve rod 3 is provided with a first annular groove 21 and a second annular groove 23. The first annular groove 21 and the second annular groove 23 are connected by a connecting groove 22. The first annular groove 21, the second annular groove 23 and the connecting groove 22 are all adapted to the gear rod 9.

[0033] A slot is provided at the bottom of the connecting rod 7 , and a connecting sleeve 10 is movably connected to the slot. A hinge rod 16 is evenly hinged on the outer surface of the connecting sleeve 10 , and one end of the hinge rod 16 away from the hinge rod 16 is hinged to the baffle 14 .

[0034] The inner wall of the material storage box 2 is evenly provided with retaining grooves 19 connected to the material inlet 18 , and the top end of the baffle 14 is fixed with a retaining piece 17 adapted to the retaining grooves 19 .

[0035] A handle 6 is fixed to the top of the connecting rod 7 .

[0036] The working principle of this device is as follows: when the user uses it, the drill bit 1 is placed on the mark where sampling is required, and the drill bit 1 is perpendicular to the bottom surface, and then the operating disk 5 is turned to drive the drill bit 1 to drill downward, and then the user can observe the scale line 4 as needed. When drilling to the soil layer that needs to be sampled, the handle 6 is turned to release the gear rod 9 from the constraint of the first annular groove 21, and then the gear rod 9 is placed in the connecting groove 22, and the handle 6 is pulled to place the gear rod 9 in the second annular groove 23, completing the constraint of the second annular groove 23 on the gear rod 9. At this time, due to the upward movement of the handle 6, the upward movement of the connecting rod 7 is realized, and then the upward movement of the connecting sleeve 10 is driven. During the online movement of the connecting sleeve 10, the angle of the hinged rod 16 is driven to change, and then the baffle 14 is driven to flip toward the inside of the storage box 2. The operating disk 5 is rotated in the opposite direction of the thread rotation direction of the first guide blade 12. At this time, the sampling blade 15 provided on the storage box 2 is subjected to the rotational force to scrape off the soil. Since the baffle 14 is flipped toward the inner side of the storage box 2, the soil scraped off by the sampling blade 15 directly falls into the interior of the storage box 2 through the feeding port 18. After rotating the operating disk 5 several times, the gear lever 9 is released from the second annular groove 23 by turning the handle 6, and the gear lever 9 is rotated into the connecting groove 22. The handle 6 is moved downward and then rotated to complete the cooperation between the gear lever 9 and the first annular groove 21. At this time, the baffle 17 at the top of the baffle 14 is adapted to the baffle groove 19 provided inside the storage box 2. At this time, the operating disk 5 is pulled upward, the sampling operation is completed, and then the discharge door 24 is opened to take out the soil sample inside the storage box 2.

[0037] The device is provided with a conical drill bit 1 and a conical storage box 2, and a first guide blade 12 and a second guide blade 13 are provided on the outer surfaces of the drill bit 1 and the storage box 2, which facilitates the sampling part to penetrate deep into the soil layer, saves the user's physical strength, and improves the user's work efficiency. By providing a stretching mechanism and a sampling blade 15, it is further convenient for the user to sample and collect deep soil, and the functionality and practicality of the device are increased. By providing a discharge trough 20 and a discharge door 24, it is further convenient for the user to take out the collected soil. The device is simple to operate, easy to use, ingenious in structure, novel in conception, strong in practicality, wide in scope of application, and conducive to promotion.

Those skilled in the art may make various modifications, additions, or substitute similar methods to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
