Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: Referring to Figures 1-6, a sampling device for heavy metal detection in crops includes a main body 1. Handles 2 are fixedly connected to the front and rear sides of the main body 1. Two electric push rods 3 are fixedly connected to the left and right sides of the main body 1, symmetrically distributed on both sides. The extension ends of both electric push rods 3 penetrate the inner wall of the main body 1 and extend into its interior. Connecting seats 4 are fixedly connected to the extension ends of the electric push rods 3, also symmetrically distributed on the extension ends of the two electric push rods 3. The device body 1 has a connecting groove 7 inside, a threaded hole 5 on the surface of the connecting seat 4, a hand-tightening bolt 6 connected inside the threaded hole 5, a connecting groove 7 inside the connecting seat 4, a cutting blade 8 snapped into the connecting groove 7, a limit hole 9 on the surface of the cutting blade 8, an installation groove 10 at the bottom of the device body 1, an installation slider 12 slidably connected inside the installation groove 10, a sample storage box 11 fixedly connected to the inner side of the installation slider 12, a sliding groove 13 on the upper side inside the sample storage box 11, an installation notch 15 on the front side of the sample storage box 11, and a sliding cover 14 slidably connected inside the installation notch 15.

[0020] Working principle: In use, the operator extends the part of the crop to be sampled into the sample storage box 11. Then, the operator activates the electric push rod 3. The two electric push rods 3 push the two connecting seats 4 closer together through their extension ends. The two connecting seats 4 then drive the two cutting blades 8 closer together to cut and sample the individual crop. The cut crop sample falls into the sample storage box 11 and is collected by the sample storage box 11. When it is necessary to replace the cutting blade 8, the locking of the cutting blade 8 can be released by removing the hand-tightening bolt 6 from the limiting hole 9 and the threaded hole 5. At this time, the operator can separate the cutting blade 8 from the connecting seat 4, which is convenient for the operator to replace the cutting blade 8. There is no need for the operator to manually cut and sample, which reduces the labor intensity of the operator, improves the sampling efficiency, and is convenient for the operator to use.

[0021] Compared with related technologies, the sampling device for heavy metal detection in crops provided by this utility model has the following beneficial effects: by setting up electric push rods 3, connecting seats 4 and other components to work with cutting blades 8, the two electric push rods 3 push the two connecting seats 4 closer together through their extension ends, and the two connecting seats 4 will drive the two cutting blades 8 closer together to cut and sample individual crops. This eliminates the need for manual cutting and sampling by staff, reduces the labor intensity of staff, improves sampling efficiency, and makes it easier for staff to use.

[0022] Example 2: Referring to Figures 1-7, the bottom of the main body 1 of the device has an installation groove 10. An installation slider 12 is slidably connected inside the installation groove 10. A sample storage box 11 is fixedly connected to the inner side of the installation slider 12. A sliding groove 13 is provided on the upper side of the inside of the sample storage box 11. An installation notch 15 is provided on the front side of the sample storage box 11. The shape of the installation slider 12 is the same as the inner wall shape of the installation groove 10, and the installation slider 12 is tightly fitted to the inner wall of the installation groove 10. A sliding cover 14 is slidably connected inside the installation notch 15. The shape and size of the sliding cover 14 are the same as the shape and size of the sliding groove 13, and the sliding cover 14 is tightly fitted to the inner wall of the sliding groove 13.

[0023] Working principle: When the sample storage box 11 is full of samples, the operator only needs to slide the mounting slider 12 out of the mounting groove 10 to slide the sample storage box 11 out of the device body 1, thereby removing the sample storage box 11 from the device body 1. At this time, the operator only needs to insert the sliding cover 14 into the sliding groove 13 of the sample storage box 11 through the mounting notch 15 to seal the sample storage box 11. Then, the operator only needs to install a new sample storage box 11 on the device body 1 to carry out sampling again, thereby improving the sampling efficiency of the device and making it convenient for operators to use.

[0024] Compared with related technologies, the sampling device for heavy metal detection of crops provided by this utility model has the following beneficial effects: by setting up a sample storage box 11 and a device body 1 for use, the sample storage box 11 can be slid out of the device body 1 by sliding the mounting slider 12 out of the mounting groove 10. At this time, the staff only needs to install the new sample storage box 11 on the device body 1 to carry out the sampling work again, thereby improving the sampling efficiency of the device and making it convenient for staff to use.
