[0029] A method for using a mine ecological restoration soil improvement device, the method comprising the following steps:

[0030] S1: Power on the motor 1-3 to drive the paddle 2-6 to rotate;

[0031] S2: Pour the soil into the feed port 2-2, and the paddle 2-6 separates the soil;

[0032] S3: Power on the water pump 3-4-4 to spray the soil remediation agent on the soil;

[0033] S4: The motor 3-7 is powered on to drive the screen plate 3-9 to rotate and break up the compacted soil.

[0034] The working principle of the present invention is:

[0035] The device is connected to an external power supply. When in use, the motor 1-3 is energized, and the belt 1-4 drives the rotating roller 2-5 to rotate, and the soil is poured into the feed port 2-2 and enters the screening box 2-1. The rotating roller 2-5 drives the paddle 2-6 to rotate, and the paddle 2-6 drives the soil to rotate in the screening box 2-1. The centrifugal force can separate the gangue in the soil, and then the paddle 2-6 drives the soil to pass through the screening net 2-3 and fall through the discharge port 2-4. After the soil is separated, the paddle 2-6 drives the gangue to continue to move and push it into the crushing pipe 2-7. The crushed stone moves downward along the crushing pipe 2-7, and continuously hits the protrusion 2-8, so that the soil adhering to the gangue can fall off and fall into the collecting box through the crushing pipe hole 2-9. In the collecting cover 2-10, the gangue slides along the crushing pipe 2-7 to the crushing recovery chamber 1-1 for collection, and the soil in the discharge port 2-4 and the collecting cover 2-10 falls on the umbrella cover 1 3-4-1. The motor 3-4-10 is energized to drive the umbrella cover 1 3-4-1 to rotate. The soil is subjected to centrifugal force along with the umbrella cover 1 3-4-1 and is thrown on the inner wall of the collecting cover 3-1. The soil slides down along the inner wall of the collecting cover 3-1. The soil remediation agent is poured into the liquid tank 3-4-2 in advance, and the water pump 3-4-4 is energized to extract the soil remediation agent in the liquid tank 3-4-2 and send it into the cavity 2 3-4-5. The soil remediation agent is sprayed out through the conical hole 3-4-6. When the soil slides to the lower end of the collecting cover 3-1, The soil remediation agent is sprayed on the soil, so that the soil remediation agent can fully contact with the soil. The rotation of motor three 3-4-10 drives the spray box 3-4-3 to rotate, and the rotation of the spray box 3-4-3 drives the scraper 3-4-7 to rotate. The rotation of the scraper 3-4-7 can prevent the soil adhering to the soil remediation agent from adhering to the inner wall of the lower end of the collecting cover 3-1. The rotating screw 3-4-8 drives the sealing plug 3-4-9 to move upward or downward in the cavity two 3-4-5, which can change the number of conical holes 3-4-6, that is, the spraying amount of the soil remediation agent can be adjusted. The sealing plug 3-4-9 moves the conical hole 3-4-6 upward to reduce the spraying amount, and the sealing plug 3-4-9 moves the conical hole 3-4-6 upward to increase the spraying amount. -4-6 setting can increase the spraying distance of soil remediation agent, ensure that soil remediation agent is sprayed on the sliding soil to avoid insufficient distance, and save soil remediation agent. The flow rate of water pump 3-4-4 is greater than the flow rate sprayed by conical hole 3-4-6. After the soil is sprayed with soil remediation agent, it falls on the inclined plate 3-6 set in the collection box 3-5. As the amount of soil increases, the soil is prone to compaction when the soil remediation agent dries up. The motor 3-7 is energized, and the sieve plate 3-9 is driven to rotate through the rotating shaft 3-8. When the sieve plate 3-9 rotates, the compacted soil can be crushed. The inclined plate 3-6 setting can facilitate the removal of soil. The soil can be taken out through the collection box outlet 3-10. The setting of a feeding pump can remove the soil faster and more conveniently.
