[0030] The extrusion rod 7 includes a rotating shaft 8 rotatably connected to the inside of the first extraction cylinder 5 and the second extraction cylinder 6, and an annularly distributed spiral blades 9 are fixedly connected to the outside of the rotating shaft 8, and the density of the spiral blades 9 inside the second extraction cylinder 6 is greater than that of the spiral blades 9 inside the first extraction cylinder 5.

[0031] The rotating shaft 8 is composed of a transport section 10, a pressurizing section 11 and a compression section 12, and the transport section 10 and the compression section 12 are both set to cylindrical structures, and the pressurizing section 11 is set to a truncated cone structure. The radius of the transport section 10 is smaller than the radius of the compression section 12, and the radius of the end of the pressurizing section 11 close to the transport section 10 is smaller than the radius of the end close to the compression section 12.

[0032] The end of the rotating shaft 8 close to the transport section 10 is fixedly connected to the drive shaft 13, and the end of the rotating shaft 8 close to the compression section 12 is fixedly connected to the limiting ball 14, and the drive shaft 13 extends to the outside of the ends of the first extraction cylinder 5 and the second extraction cylinder 6.

[0033] An end of the first extraction cylinder 5 close to the limiting ball 14 and an end of the discharge port 16 away from the limiting ball 14 are connected to each other through a pipeline, and a feeding hopper 15 is provided at the end of the top of the first extraction cylinder 5 away from the limiting ball 14, and a discharge port 16 is provided at the bottom of the end of the second extraction cylinder 6 away from the driving shaft 13. The middle sections of the first extraction cylinder 5 and the second extraction cylinder 6 are both provided with drainage holes 17 distributed in an annular shape and at equal intervals, and the drainage holes 17 cover the outside of the compression section 12 and the pressurizing section 11, and a filter is fixedly connected to the inside of each drainage hole 17.

[0034] The outside of the first extraction cylinder 5 and the second extraction cylinder 6 are both fixedly connected with a sealing sleeve 18, and the sealing sleeve 18 completely covers the drainage hole 17. The two sealing sleeves 18 are connected to each other, and a drainage port 19 is provided at the bottom of the sealing sleeve 18 outside the second extraction cylinder 6. A discharge pipe 20 is fixedly connected to the lower end of the discharge port 16, and two symmetrically distributed handles 21 are fixedly connected to the outside of the bottom of the discharge pipe 20.

[0035] A drain pipe 22 is fixedly connected to the inside of the fixed ring 3, and a drive assembly 23 is fixedly connected to the top of the two support frames 2. The upper end of the drain pipe 22 is interconnected with the discharge port 16, and the drive assembly 23 is composed of a motor and a reducer, and the output end of the reducer is fixedly connected to the drive shaft 13.

[0036] Example 2:

[0037] Based on the first embodiment, the specific working principle is as follows:

[0038] The filtering device for extracting natural plants crushes plants. After the crushing, the plants are added from the feeding hopper 15 to the interior of the first extraction cylinder 5. When the plants are inside the first extraction cylinder 5, the driving assembly 23 drives the squeezing rod 7 to rotate inside the first extraction cylinder 5, so that the plants are transported, crushed and squeezed inside the first extraction cylinder 5, so that the plant juice enters the interior of the sealing sleeve 18 through the drainage hole 17, and the plant juice is collected by the sealing sleeve 18. The plants squeezed inside the rotating shaft 8 will enter the interior of the second extraction cylinder 6 through the pipeline, and the squeezing rod 7 inside the second extraction cylinder 6 will crush and squeeze the plants for the second time, so that the plants are processed more fully.

[0039] During the process of the plant passing through the first extraction cylinder 5 for processing, the plant will move outside the rotating shaft 8 and enter between the transport section 10 and the inside of the first extraction cylinder 5 through the hopper 15, so that the plant moves from the outside of the rotating shaft 8 toward the compression section 12. The plant will move between the pressurizing section 11 and the inside of the first extraction cylinder 5. The radius of the end of the pressurizing section 11 near the transport section 10 is smaller than the radius of the end near the compression section 12. As the plant moves toward the compression section 12, the space between the pressurizing section 11 and the inside of the first extraction cylinder 5 will gradually shrink, and the plant will be squeezed inside the gradually shrinking space.

[0040] During the squeezing of the plant inside the first extraction cylinder 5 and the second extraction cylinder 6, the density of the spiral blades 9 inside the second extraction cylinder 6 is greater than that inside the first extraction cylinder 5. Therefore, during the squeezing of the plant by the second extraction cylinder 6, the squeezing force on the plant will be greater than the squeezing force on the plant inside the first extraction cylinder 5. At the same time, when the plant juice enters the sealing sleeve 18 through the drainage hole 17, the plant juice will be filtered by the filter inside the drainage hole 17 before entering the sealing sleeve 18, because the filter is provided inside the drainage hole 17, so that the pure plant juice enters the rotating shaft 8.

[0041] The sealing sleeves 18 respectively located on the outside of the first extraction cylinder 5 and the second extraction cylinder 6 are connected to each other, so that the plant juice inside the sealing sleeve 18 enters the inside of the discharge pipe 22 through the discharge port 19, and at the same time, the plant residue will be discharged into the inside of the discharge pipe 20 through the discharge port 16. Since the discharge pipe 20 is set to a corrugated structure, the position of the lower end of the discharge pipe 20 is adjusted by pulling the two handles 21, so that the plant residue can be discharged from different angles.
