[0026] like Figure 1-9 As shown, a manual soil grinding and screening device includes a base 11, a grinding container 3 is connected to the top of the base 11, a grinding assembly is installed at the bottom of the grinding container 3, a driving mechanism for driving the grinding assembly to work is installed inside the base 11, a slot 11-1 is opened on the side of the base 11, a hand pull ring 10 is inserted in the slot 11-1, and the hand pull ring 10 is connected to the driving mechanism, a screen 2 is arranged near the top surface of the grinding container 3, and a screening container 1 is detachably connected to the top of the grinding container 3; the screen 2 can be selected according to actual conditions, and the screen 2 depends on the particle size requirements of the experiment, and the corresponding screen can be rotated for any particle size.

[0027] like Figure 2 , 4 As shown, the grinding assembly includes a vertical rotating rod 13 , on which a sawtooth grinding sheet 4 and a folded grinding sheet 12 are mounted, and the sawtooth grinding sheet 4 is located above the folded grinding sheet 12 .

[0028] like Figure 2 , 3As shown in Figure 5, the driving mechanism includes a wire drum 9, on which a pull rope 6 is wound, one end of which is connected to the hand pull ring 10, a coil spring 5 is arranged below the wire drum 9, and a mounting groove 11-2 is arranged at the bottom of the base 11, the coil spring 5 is installed in the mounting groove 11-2, and an inner ring fixing ring 14 is connected to the inside of the mounting groove 11-2, one end of the coil spring 5 is connected to the inner ring fixing ring 14, and the other end of the coil spring 5 is connected to the side wall of the mounting groove 11-2, and the coil spring 5 is limited by the vertical edge of the mounting groove 11-2, the center of the wire drum 9 is connected to the vertical rotating rod 13, and the top surface of the wire drum 9 is connected to the ratchet 8 through a rotating shaft. A spring sheet 7 is provided on one side of the ratchet 8, and one end of the spring sheet 7 is fixedly connected to the top surface of the wire drum 9; when in use, the hand pull ring 10 is pulled outward, the hand pull ring 10 drives the draw rope 6 to loosen from the wire drum 9, the draw rope 6 drives the wire drum 9 to rotate, and the spring sheet 7 rotates together with the wire drum 9. When the draw rope 6 is pulled to the maximum length, the coil spring 5 is unfolded to the extreme position, the spring sheet 7 contacts one side of the ratchet 8, and the ratchet 8 limits the spring sheet 7; the hand pull ring 10 is released, and the coil spring 5 returns to its original state after the external force is lost. Under the action of the elastic force of the coil spring 5, the wire drum 9 is driven to rotate in the opposite direction, and the draw rope 6 is rewound around the wire drum 9. When the coil spring 5 returns to its original state, the spring sheet 7 contacts the other side of the ratchet 8, and the ratchet 8 limits the spring sheet 7.

[0029] During grinding, the hand pull ring 10 is pulled outward, and the hand pull ring 10 drives the pull rope 6 to loosen from the wire drum 9, and the pull rope 6 drives the wire drum 9 to rotate. The rotation of the wire drum 9 drives the vertical rotating rod 13 at its center to rotate, and the rotation of the vertical rotating rod 13 drives the serrated grinding sheet 4 and the folded grinding sheet 12 to grind the soil, and drives the coil spring 5 to contract during the rotation of the vertical rotating rod 13; then, the hand pull ring 10 is released, and the coil spring 5 returns to its original state after the external force is lost, and the vertical rotating rod 13 is driven to rotate in the opposite direction under the elastic force of the coil spring 5. The reverse rotation of the vertical rotating rod 13 drives the serrated grinding sheet 4 and the folded grinding sheet 12 to grind the soil, and the pull rope 6 is rewound around the wire drum 9; the hand pull ring 10 is continuously stretched and contracted in the above manner to fully grind the soil.

[0031] like Figure 7As shown, four slots 1-1 are provided at the bottom of the screening container 1, and the cross-section of the slots 1-1 is set to be L-shaped. A block 3-2 matching the slots 1-1 is connected to the top outer wall of the grinding container 3; the slots 1-1 and the blocks 3-2 form a snap structure, and the screening container 1 and the grinding container 3 are detachably connected together through the snap structure; the screening container 1 is placed above the grinding container 3, the slots 1-1 are aligned with the blocks 3-2, the blocks 3-2 are inserted into the slots 1-1, and then the screening container 1 is rotated, so that the screening container 1 is installed above the grinding container 3.

[0032] The use process of the present invention is as follows:

[0033] Step 1: Put the soil to be ground into the grinding container 3. The amount of soil is preferably half of the volume of the grinding container 3, so that there is enough space for fast grinding.

[0034] Step 2: insert the sieve 2 with a specific outlet particle size, align the four edge notches 2-1 of the sieve 2 with the rectangular protrusions 3-1 on the inner wall of the grinding container 3, and the sieve 2 falls on the edge platform of the grinding container 3 after being inserted, and rotate the sieve 2 to displace the protrusions 3-1 and the notches 2-1, thereby completing the installation of the sieve 2;

[0035] Step 3, placing the screening container 1 above the grinding container 3, aligning the card slot 1-1 with the card block 3-2, inserting the card block 3-2 into the card slot 1-1, and then rotating the screening container 1, so that the screening container 1 is installed above the grinding container 3;

[0036] Step 4: continuously stretch and contract the hand pull ring 10 to drive the sawtooth grinding sheet 4 and the folded grinding sheet 12 on the vertical rotating rod 13 to grind the soil;

[0037] Step 5: After grinding, turn the container over and sieve the soil by shaking the container;

[0038] Step six, disassembling the screening container 1 to obtain the ground soil.
