When it is necessary to collect root secretions, the roots need to be collected first, and the hydraulic telescopic rod 6 is started to drive the screw 15 to rise. The screw 15 first enters the first cylinder 21. Due to the threaded action of the screw 15 and the first cylinder 21, the screw 15 drives the first cylinder 21 to rotate during the rising process.

When the screw 15 moves out of the first cylinder 21, the multiple groups of clamping rings 1 are just clamped on the multi-layer plant roots and fixed respectively. The plant roots can be layered and fixed before being cut off, which is not only convenient for cutting, but also convenient for subsequent layered sampling.

[0038] The screw 15 then enters the second cylinder 19, and the second cylinder 19 is driven to rotate due to the threaded action. The second cylinder 19 drives the cutting knife 13 to rotate around the outer periphery of the collecting box 10 through the connecting rod 14. When the screw 15 moves out of the second cylinder 21, the cutting knife 13 rotates exactly one circle, thereby cutting off the clamped multi-layer root system, and the root system can be automatically and quickly cut off; the screw 15 then enters the collecting box 10 through the jack 20, and can lift the incubator 12 upward, making it convenient to replace the incubator 12; the clamping, cutting, and unloading tasks can be completed through only one driving device, the hydraulic telescopic rod 6, which reduces equipment costs and has stronger linkage.
