[0002] With the vigorous development of industry, a series of environmental pollution problems have been caused, such as air pollution, water pollution, soil pollution, etc. When investigating soil pollution problems, soil is often collected for chemical element analysis. However, the collected soil will clump, which is not conducive to soil research. Therefore, the soil needs to be ground before soil research.

[0003] Patent document CN220027301U discloses a soil grinding device, "including: a fixed ring and a base plate; a support plate, the support plates are respectively fixedly installed on both sides of the fixed ring, and both ends of the bottom of the two support plates are provided with sliding cavities, a spring is fixedly installed on the top of the inner side of the sliding cavity, an extension rod is fixedly installed on the bottom of the spring, and a shovel plate is fixedly installed on the bottom of the extension rod; a first support plate, the first support plate is fixedly installed on the top of the base plate, a grinding seat is fixedly installed on the top of the first support plate, and a baffle is fixedly installed on the top of the first support plate. The utility model provides a soil grinding device, which cooperates with each other through structures such as a fixed ring, a support plate, a sliding cavity, a spring, an extension rod, a shovel plate, a baffle, a storage frame, a slide plate and a handle. When in use, it is convenient to collect the ground soil, which increases work efficiency and is convenient for users to use."

[0004] When the above device is in use, the driving assembly drives the grinding ring to rotate on the outer side of the grinding seat, thereby grinding the soil, so that the ground soil falls on the top of the first support plate on the inner side of the baffle.

[0028] The rotating disk 5 is inclined so that the center of the top of the rotating disk 5 and the center of the bottom of the rotating disk 5 are on different vertical lines;

[0029] When the storage box 7 is graded by the base 1, the storage box 7 is placed on the top of the base 1 so that the limit block 6 is inserted into the bottom of the storage box 7. Then the first drive motor 2 is powered on, and the output end of the first drive motor 2 drives the drive rod 3 to rotate, the drive rod 3 drives the rotating disk 5 at the top to rotate, the rotating disk 5 drives the limit block 6 at the top to rotate, the limit block 6 drives the storage box 7 at the top to rotate, the storage box 7 drives the first connecting ring 8 at the top to rotate, and the first connecting ring 8 drives the second connecting ring 10 at the top to rotate. The second connecting ring 10 drives the grinding box 12 on the top to rotate, and swings the soil in the grinding box 12, so that the soil falls into the second connecting ring 10 through the circular opening at the bottom of the grinding box 12, and the soil falls on the second screen 11, and the finer soil falls into the first connecting ring 8 through the holes of the second screen 11, and the finer soil falls into the storage box 7 through the holes of the first screen 9. At this time, three kinds of soils of different coarseness are respectively accumulated on the storage box 7, the first screen 9 and the second screen 11, thereby completing the soil grading.

[0030] See also Figures 1 to 6 A grading soil grinding device: the left and right sides of the inner wall of the grinding box 12 are slidably connected with a connecting plate 13, the front of the connecting plate 13 is fixedly connected with a limiting block 14, the front of the limiting block 14 is fixedly connected with a first magnet 15, and the tail of the connecting plate 13 is fixedly connected with a push-pull plate 16.

[0031] When the soil is graded through the screen, the push-pull plate 16 is pulled outward, so that the push-pull plate 16 pulls the tail connecting plate 13 to slide outward, and the connecting plate 13 drives the tail limiting block 14 to slide to both sides. At this time, the limiting block 14 slides into the inner wall of the grinding box 12 and separates the two groups of first magnets 15. At this time, the round opening at the bottom of the grinding box 12 is unblocked, so that the soil can fall from the round hole at the bottom of the grinding box 12.

[0032] See also Figures 1 to 6 A grading soil grinding device: a first protective cover 17 is fixedly connected to the top of a base 1, a second protective cover 18 is rotatably connected to the front of the first protective cover 17, a transparent glass 19 is fixedly connected to the surface of the second protective cover 18, and a second magnet 20 is fixedly connected to the left side of the second protective cover 18.

[0033] When the device is protected by the protective cover, the soil is placed in the grinding box 12, and the grinding stone 27 is placed in the grinding box 12, and then the second protective cover 18 is rotated so that the second protective cover 18 rotates and fits the first protective cover 17, thereby enclosing the grinding stone 27 in the two sets of protective covers. At this time, the second magnet 20 is magnetically connected to the first protective cover 17, thereby connecting and fixing the first protective cover 17 and the second protective cover 18, and the staff can observe the internal working conditions through the transparent glass 19.

[0034] See also Figures 1 to 6 A grading soil grinding device: a second driving motor 25 is fixedly connected to the top of a connecting shell 24, a rotating rod 26 is installed at the output end of the second driving motor 25, and the surface of the rotating rod 26 is rotatably connected to the inner wall of the connecting shell 24, and a grinding stone 27 is fixedly connected to the bottom end of the rotating rod 26.

[0035] When the soil is ground by the grinding stone 27, the connecting shell 24 is pulled upward, so that the connecting shell 24 drives the connecting block 23 to move upward, and the connecting block 23 drives the telescopic column 22 at the bottom to slide out of the supporting column 21 and move upward, so that there is a large gap between the grinding stone 27 and the grinding box 12, and then the soil is put into the grinding box 12, and then the grinding stone 27 is lowered into the grinding box 12, and then the second driving motor 25 is powered on, so that its output end drives the rotating rod 26 to rotate, and the rotating rod 26 drives the grinding stone 27 at the bottom to rotate slowly, so that the grinding stone 27 can grind the soil.

[0036] See also Figures 1 to 6 , a grading soil grinding device: springs 28 are connected to the left and right sides of the inner wall of the limit block 6, and a fixing block 29 is connected to the front end of the spring 28.

[0037] When the storage box 7 is fixed by the limit block 6, the limit block 6 is inserted to the bottom of the storage box 7. At this time, the storage box 7 squeezes the fixing block 29, so that the fixing block 29 shrinks into the inner wall of the limit block 6. After the limit block 6 is inserted into the inner top wall of the storage box 7, the spring 28 rebounds, so that the spring 28 pushes the fixing block 29, so that the fixing block 29 is inserted into the inner wall of the storage box 7, so that the limit block 6 can be connected and fixed to the storage box 7.

[0038] Working principle: push the push-pull plate 16 toward the middle so that the two sets of limiting blocks 14 fit together, thereby blocking the opening at the bottom of the grinding box 12, and then place the soil in the grinding box 12, and then place the storage box 7 on the rotating disk 5 so that the limiting block 6 and the fixing block 29 fix the storage box 7, and then put the grinding stone 27 into the grinding box 12, and rotate the second protective cover 18 so that the first protective cover 17 and the second protective cover 18 fit together and fix, so that the grinding stone 27 and other devices can be protected to prevent accidental touch and soil spillage, and then the second drive motor 25 is connected to the rear power supply, so that the grinding The stone 27 rotates slowly and grinds the soil. After grinding, the second protective cover 18 is opened, and the grinding stone 27 is moved upward to separate from the grinding box 12, and then the push-pull plate 16 is pulled to both sides so that the opening at the bottom of the grinding box 12 is not closed. Then the first drive motor 2 is powered on, so that the rotating disk 5 drives the grinding box 12 to rotate, thereby swinging the soil in the grinding box 12 and falling into the second connecting ring 10, and the soil is graded according to coarse and fine through the first sieve 9 and the second sieve 11. After grading, the storage box 7 and the first connecting ring 8 are rotated to separate them, so that the three types of soil can be poured out for research.
