Description

Technical Field

[0001] The invention relates to the technical field of steam sterilization, in particular to a soil steam sterilization device for planting. Background Art

[0002] Protected horticulture is a year-round practice. The high temperatures and humidity within greenhouses allow certain pathogens, insect eggs, and pests to multiply year after year, accumulating in large quantities in the growing medium or soil, making them difficult to manage. Furthermore, protected horticulture is highly specialized, with a relatively small number of crop varieties cultivated. Consequently, continuous cropping is prevalent, leading to the continuous accumulation of insect eggs, fungi, and viruses in the soil. This, in turn, leads to the frequent occurrence of soil-borne pests and diseases, severely restricting the development of protected cultivation.

[0003] In the prior art, steam is input into the soil through a pipe and is retained on the soil surface by a covering cloth to achieve steam sterilization of the soil.

[0004] However, since steam is output through pipes and there are air outlet holes on the surface of the pipes, it is necessary to adjust the angle of the pipes when laying the pipes to prevent the air outlet holes from being pressed down, resulting in poor steam discharge.

After the pipe 1 is placed on the ground, the supporting block 18 is inserted into the inside of the telescopic groove 21 under extrusion, and the surface of the supporting block 18 is supported on the surface of the fixing ring 5, so that the sleeve ring 9 remains stable.

[0030] Example 2: Based on Example 1, a cover cloth 2 is provided on the top of the pipe 1, and multiple sets of fixing rings 5 ​​are fixed on the surface of the pipe 1. The multiple sets of fixing rings 5 ​​are located at the bottom of the cover cloth 2. The surface of the fixing ring 5 is provided with a thread 8, and the screw ring 7 is screwed onto the outside of the thread 8. The surface of the fixing ring 5 is provided with multiple sets of ring grooves 3, and the surface of the fixing ring 5 is provided with multiple sets of through holes 6. The through holes 6 are communicated with the interior of the pipe 1. The end of the pipe 1 is connected to the steam input device. The surface of the fixing ring 5 is provided with a circular ring, and the sleeve ring 9 is located between the circular ring and the limit ring 4, and the sleeve ring 9 can move between the limit ring 4 and the circular ring. After the screwing ring 7 is rotated, it is supported on the circular surface of the fixed ring 5, so that a gap is left between the screwing ring 7 and the limit ring 4, and the sleeve ring 9 is located in the gap. Sealing rings are provided on both sides of the sleeve ring 9. When the sleeve ring 9 moves on the surface of the fixed ring 5, the sealing ring can be compressed when it contacts the circular surface, so that the sleeve ring 9 moves. By screwing the screwing ring 7, the sleeve ring 9 can move on the surface of the fixed ring 5. When the sleeve ring 9 moves, the sleeve tube 17 and the plug rod 22 move with the sleeve ring 9. Since multiple sets of ring grooves 3 are provided on the surface of the fixed ring 5, the plug rod 22 can be extended and retracted in the sleeve tube 17.

[0031] The sleeve ring 9 can rotate and move on the surface of the fixed ring 5. Two groups of air outlet pipes 10 are fixed on the surface of the sleeve ring 9. The air outlet pipes 10 move with the sleeve ring 9. An extension pipe 11 is fixed to the bottom of the air outlet pipe 10. A sealing cover 12 is screwed to the bottom of the extension pipe 11. A storage hole 15 is provided inside the extension pipe 11. A telescopic groove 21 is provided at the bottom of the sleeve ring 9. A top holding block 18 is inserted in the telescopic groove 21. The top holding block 18 can move in the telescopic groove 21. An extension plate 20 is fixed to the bottom of the top holding block 18. The extension plate 20 moves with the top holding block 18. A spring 19 is provided on the surface of the extension plate 20. The other end of the spring 19 is connected to the bottom of the sleeve ring 9.

[0032] The inside of the air outlet pipe 10 is provided with a telescopic rod 13, and the telescopic rod 13 can move in the air outlet pipe 10. An extension rod 14 is fixed to the surface of the telescopic rod 13. The extension rod 14 moves with the telescopic rod 13, and the extension rod 14 is provided with multiple groups. The end of the telescopic rod 13 is fixed with a plug rod 22. The end of the telescopic rod 13 inside the air outlet pipe 10 on the other side is fixed with a sleeve tube 17. The plug rod 22 is plugged into the inside of the sleeve tube 17. The sleeve tube 17 can telescope and move in the plug rod 22. A second spring is provided inside the sleeve tube 17. The second spring top Holding the end of the plug-in rod 22, when the sleeve tube 17 and the plug-in rod 22 move on the surface of the fixed ring 5, the sleeve tube 17 and the plug-in rod 22 can enter the interior of the annular groove 3, so that the plug-in rod 22 can telescope and move inside the sleeve tube 17, and the sleeve tube 17 and the plug-in rod 22 drive the telescopic rod 13 to move. Since there are multiple sets of annular grooves 3 on the surface of the fixed ring 5, the plug-in rod 22 can telescope and move in the sleeve tube 17, and the telescopic rod 13 can move back and forth inside the air outlet pipe 10, and the extension rod 14 on the surface of the telescopic rod 13 moves with the telescopic rod 13.

[0033] The cover cloth 2 is laid on the soil surface, and the pipe 1 is placed inside the cover cloth 2. Steam is blown out from the inside of the pipe 1. A fixing ring 5 is fixed on the surface of the pipe 1. A through hole 6 is opened on the surface of the fixing ring 5. The outside of the fixing ring 5 is covered with a sleeve ring 9. The steam ejected from the through hole 6 is located inside the sleeve ring 9 and ejected from the air outlet pipe 10 on the surface of the sleeve ring 9. Since the sleeve ring 9 can rotate on the surface of the fixing ring 5, when the pipe 1 is laid, the opening of the air outlet pipe 10 is facing upward under the action of gravity. When the air outlet pipe 10 is blocked with soil, the screwing ring 7 is screwed, and the sleeve ring 9 can move on the surface of the fixing ring 5. When the sleeve ring 9 moves, the sleeve pipe 17 and the plug rod 22 moves with the sleeve ring 9. Since multiple sets of ring grooves 3 are provided on the surface of the fixed ring 5, the connecting rod 22 is telescopic in the sleeve tube 17, and the telescopic rod 13 is reciprocated inside the air outlet pipe 10. The extension rod 14 on the surface of the telescopic rod 13 moves with the telescopic rod 13 to prevent soil from being blocked inside the air outlet pipe 10, and the soil can fall into the storage hole 15. The sealing cover 12 at the bottom of the extension tube 11 is screwed, and the soil can be taken out from the storage hole 15. After the pipeline 1 is placed on the ground, the supporting block 18 is inserted into the telescopic groove 21 under extrusion, and the surface of the supporting block 18 is supported on the surface of the fixed ring 5, so that the sleeve ring 9 remains stable.
