A traction rod 26 is fixed between two adjacent dial plates 25; a through hole 30 is opened on the surface of the lifting plate 27, and a guide rod 31 is inserted into the inside of the through hole 30. The guide rod 31 is fixed between the top surface of the lifting groove 22 and the bottom surface of the lifting groove 22. A spring 32 is sleeved on the rod body of the guide rod 31, and the spring 32 is fixed between the lifting plate 27 and the top surface of the lifting groove 22.

[0037] When in use, the nutrient solution mixed with clean water can be directly injected into the liquid storage chamber 11 through the injection tube 12 for storage and waiting for use; when it is necessary to add nutrient solution to the clean water inside the liquid storage chamber 11, and the clean water and nutrient solution are mixed for standby use, the nutrient solution is injected into the liquid storage chamber 11 through the injection tube 12, and then both hands are respectively placed in the finger grooves 28 on the surfaces of the two lifting plates 27, and the lifting plates 27 are pushed and pulled up and down, and the lifting plates 27 drive the traction plate 24 and the paddle plate 25 to move back and forth up and down, so as to realize the mixing of clean water and nutrient solution inside the liquid storage chamber 11 The body is shaken and mixed so that the clean water and the nutrient solution are mixed more evenly. After the mixing is completed, the lifting plate 27 is squeezed and pushed to overlap the bottom surface of the lifting tank 22, and then the hand-tightened screw rod 29 is screwed to fix the lifting plate 27 to the bottom surface of the lifting tank 22. In this way, the paddle plate 25 will not be floated up by the mixed liquid inside the liquid storage chamber 11, triggering the switch of the pump body 17, and injecting the mixed liquid in the liquid storage chamber 11 into the liquid collecting tank 15, and then seeping into the soil through the seepage hole 16; in this way, the liquid storage chamber 11 is used not only as a storage structure for liquid, but also as a mixing space for liquid.

[0038] A liquid storage tank 20 is provided at the bottom end of the breeding box body 1, and an absorbent cotton pad 19 is provided on the bottom plate of the breeding box body 1. An absorbent cotton core 21 is fixed on the surface of the absorbent cotton pad 19, and one end of the absorbent cotton core 21 extends into the liquid storage tank 20. A bottom groove 33 is provided on the bottom surface of the breeding box body 1 for aligning two breeding box bodies 1 when they are stacked; the liquid storage tank 20 is an annular groove, and an embedded groove 18 is provided on the top surface of the bottom plate of the breeding box body 1. An absorbent cotton pad 19 is fixed inside the embedded groove 18. The absorbent cotton pad 19 is a "T"-shaped circular plate, and the top plate of the absorbent cotton pad 19 is overlapped on the top surface of the top plate of the breeding box body 1. The absorbent cotton core 21 is an "L"-shaped rod, and a plurality of absorbent cotton cores 21 are provided, and the plurality of absorbent cotton cores 21 are distributed in a circle with the absorbent cotton pad 19 as the central axis.

[0039] During use, when there is too much liquid inside the breeding box body 1, the absorbent cotton pad 19 absorbs the liquid until it is saturated and transfers the saturated liquid to the liquid storage tank 20 through the absorbent cotton core 21. The liquid storage tank 20 temporarily stores the excess liquid, and the absorbent cotton core 21 absorbs the liquid in the liquid storage tank 20 and transfers it to the absorbent cotton pad 19. The saturated liquid absorbed by the absorbent cotton pad 19 seeps into the soil, thereby moistening the soil and avoiding water accumulation at the bottom of the trough of the breeding box body 1. When two breeding box bodies 1 are stacked, the top of one breeding box body 1 is inserted into the bottom groove 33 at the bottom end of the other breeding box body 1, so as to align the two stacked breeding box bodies 1, thereby avoiding deviation when multiple breeding box bodies 1 are stacked.

[0040] The process of using the breeding box for earthworm breeding is as follows:

[0041] Ensure that the breeding box body 1 is not damaged and that all components (such as the top groove 2, the reserved groove 3, the air vent 4, etc.) are installed completely. Insert the barrier cover 6 into the reserved groove 3 to ensure that it is in contact with the bottom surface of the reserved groove 3. At this time, the bottom surface of the pick-up groove 7 is coplanar with the bottom surface of the top groove 2. If the barrier cover 6 needs to be fixed, it can be screwed through the hand-tightened screw 10 in the pick-up groove 7. The rubber corner piece 9 is fixed in the side groove 8 to ensure that it forms an anti-slip limit for the barrier cover 6. Put an appropriate amount of soil into the breeding box body 1, and the top surface of the soil should be below the air vent 4. Put the earthworms in the soil. When it is necessary to ventilate the inside of the breeding box body 1, insert your fingers into the pick-up groove 7 and pull the barrier cover 6 upward. After the barrier cover 6 is suspended and limited, the two groups of air vents 4 form convection in the air, which is convenient for ventilation. Inject clean water or nutrient solution into the liquid storage chamber 11 through the injection tube 12, and use the screw-on sealing cap 13 to seal it. If you need to mix clean water and nutrient solution, you can directly inject it through the injection tube 12. Put your hands in the finger grooves 28 on the surface of the two lifting plates 27, push and pull the lifting plates 27 up and down, and shake and mix the liquid inside the liquid storage chamber 11 through the dial plate 25. After the mixing is completed, push the lifting plate 27 to overlap the bottom surface of the lifting tank 22, and screw the hand screw 29 to fix it. Trigger the switch of the pump body 17 to inject the mixed liquid in the liquid storage chamber 11 into the liquid collecting tank 15. The liquid inside the liquid collecting tank 15 seeps into the soil through multiple seepage holes 16 to moisten the soil. When the liquid inside the breeding box body 1 is too much, the absorbent cotton pad 19 absorbs the liquid and becomes saturated. The saturated liquid is transferred to the liquid storage tank 20 through the absorbent cotton core 21 for temporary storage. The absorbent cotton core 21 then absorbs the liquid in the liquid storage tank 20 and transfers it to the absorbent cotton pad 19, and the absorbent cotton pad 19 absorbs the saturated liquid and seeps into the soil. Insert the top of one breeding box body 1 into the bottom groove 33 at the bottom of another breeding box body 1 to align the two stacked breeding box bodies 1. The design of the bottom groove 33 ensures that there will be no deflection when multiple breeding box bodies 1 are stacked.
