Description

Technical Field

[0001] This invention relates to the field of soil disinfection technology, specifically to a soil disinfection device for the prevention and control of ginseng root rot and its usage method. Background Technology

[0002] Ginseng root rot is a serious soil-borne disease caused by Fusarium fungi. It mainly damages the roots of ginseng and is one of the major diseases that cause significant economic losses in ginseng cultivation. Soil disinfection devices for the prevention and control of ginseng root rot refer to mechanical equipment specifically designed to kill pathogens in the soil that cause ginseng root rot, mainly Fusarium oxysporum and Fusarium solani. These devices are categorized according to their disinfection methods, including steam disinfection devices (using high-temperature steam above 100℃ to directly kill fungi and bacteria in the soil, destroying the cell structure of pathogens through thermal effects), flame disinfection devices (heating the soil surface directly with 800-1000℃ flames to denature and inactivate the proteins of pathogens in the soil, thus achieving disinfection), and radio frequency disinfection devices, etc.

[0003] However, when using existing steam sterilization devices, the steam penetrates slowly into the soil. Furthermore, to ensure penetration, multiple steam needles typically need to be inserted into the soil beforehand, requiring a lengthy preparation time and resulting in low sterilization efficiency. Additionally, adding chemicals to enhance the sterilization effect necessitates supervision, and the inhalation of the chemical-laden steam by the supervisor could be harmful to their health. Therefore, the sterilization efficiency and safety do not meet current requirements. To address this, we propose a soil sterilization device for the prevention and control of ginseng root rot, along with its application method. Summary of the Invention

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Please see Figures 1 to 6 An embodiment of the present invention provides a soil disinfection device for the prevention and control of ginseng root rot, including a buried steam disinfection mechanism 24. The buried steam disinfection mechanism 24 includes an L-shaped buried disinfection device shell 1 and multiple synchronous pushing mechanisms. An evaporation tank 3 is provided on the lower side inside the L-shaped buried disinfection device shell 1. Multiple heating pipes 6 are fixedly installed inside the evaporation tank 3, and steam disinfection liquid 7 located inside the evaporation tank 3 is provided on the outside of the multiple heating pipes 6. Above the evaporation tank 3, there are multiple stainless steel metal strips 21, the number of which corresponds to the synchronous pushing mechanism, and fixed to the outer surface of the L-shaped buried disinfection device shell 1. Both sides of the outer surface of the stainless steel metal strips 21 are provided with multiple circular through holes 22. Each circular through hole 22 has a slidable permeation tube head 14 that communicates with the interior of the evaporation tank 3. The outer surface of the permeation tube head 14 is provided with multiple rings of circular through holes 15, and the permeation tube head 14 located inside the circular through holes 22 on both sides of the outer surface of the same stainless steel metal strip 21 can be moved synchronously outward or inward by the synchronous pushing mechanism. A control panel 23 is fixedly installed on one side of the upper end face of the buried steam disinfection mechanism 24. The entire equipment can be controlled through the control panel 23. When ginseng needs to be planted, fill the space between the upper surface of the L-shaped buried disinfection device and the inner side of the U-shaped soil baffle 201 with soil, then disinfect it. After 7-10 days of treatment, plant the ginseng in this disinfected soil. The buried steam sterilization mechanism 24 also includes a liquid addition tank 4. The lower side of the outer surface of the liquid addition tank 4 is fixedly connected to an addition pipe 5 that communicates with the interior of the evaporation tank 3. When the planted ginseng has been completely collected and the soil between the L-shaped buried sterilization device shell 1 and the U-shaped soil baffle 201 needs to be sterilized, steam sterilization liquid 7 is poured into the inside of the liquid addition tank 4. Then, the steam sterilization liquid 7 is poured into the contents of the evaporation tank 3 through the liquid addition tank 4 and the addition pipe 5 installed on the outer surface of the liquid addition tank 4. When the liquid addition tank 4 is started, the heating pipe 6 is started through the control panel 23 to heat the steam sterilization liquid 7 and turn it into sterilization steam.

[0020] The synchronous pushing mechanism includes a drive motor 8. The output shaft of the drive motor 8 is connected to a threaded lifting rod 9 via a coupling. An internal threaded column 10 is installed on the upper side of the outer surface of the threaded lifting rod 9 via a threaded structure. A lower pressure plate 11, which is slidably installed inside a stainless steel metal strip 21, is connected above the internal threaded column 10. Both sides of the lower end face of the lower pressure plate 11 are inclined surfaces 12. When the heating tube 6 is started to heat the steam disinfectant 7, the drive motor 8 is started to drive the threaded lifting rod 9 connected to it to rotate. Since the upper end face of the internal threaded column 10, which is installed on the outer surface of the threaded lifting rod 9 via a threaded structure, is connected to the lower pressure plate 11, the internal threaded column 10 cannot rotate on its own. When the threaded lifting rod 9 rotates, the internal threaded column 10, which is threaded to it but cannot rotate on its own, will move up and down accordingly. When the internal threaded column 10 moves downward, the lower pressure plate 11 connected to it will also move downward along with it.

[0021] Multiple push plates 13 are provided below the inclined surface 12, and the surface of the push plate 13 facing the nearest permeable tube head 14 is fixed to the permeable tube head 14; as the lower pressure plate 11 descends, the inclined surface 12 located on the lower end surface of the lower pressure plate 11 will contact the upper end surface of the push plate 13 and push the push plate 13 outward. As the push plate 13 gradually moves outward, the top end of the permeable tube head 14 fixed to it will gradually insert into the soil. As the disinfection steam gradually rises, it will enter the interior of the permeation head 14 through the rear end of the permeation head 14, and then penetrate into the soil through the circular through hole 15 on the outer surface of the permeation head 14, thereby performing steam disinfection treatment on the soil from the inside out. The above technical solution enables steam sterilization directly from the inside out. It reduces the time required for steam to penetrate deep into the soil and improves the steam sterilization efficiency of the equipment. At the same time, the faster penetration rate can reduce the energy required for steam sterilization and reduce the operating cost of the equipment. When the buried steam sterilization mechanism 24 is activated to sterilize the soil, the steam sterilization liquid 7 is poured into the liquid addition tank 4 in advance, and then the heating tube 6 and the drive motor 8 are activated through the control panel 23. The above technical solution reduces the preparation steps of the equipment in advance, making the use of the equipment more convenient and thus reducing the preparation time for the use of the equipment.

[0022] A connecting block 18 is fixed to the upper end face of the permeation tube head 14. A metal rod 19 is fixedly connected to the outer surface of the connecting block 18 and slidably connected to the stainless steel metal strip 21. A spring 20 is sleeved on the outer surface of the metal rod 19, and the two ends of the spring 20 are respectively connected to the inner wall of the connecting block 18 and the stainless steel metal strip 21. When the permeation tube head 14 is pushed outward, the connecting block 18 fixed to it will move outward together and squeeze the spring 20. When the disinfection treatment is completed, when the lower pressure plate 11 is moved upward by the drive motor 8, the reaction force of the squeezed spring 20 can gradually push the permeation tube head 14 back into the interior of the stainless steel metal strip 21.

[0023] Each circular through-hole 15 has a stainless steel metal support mesh 16 fixed inside. The surface of the stainless steel metal support mesh 16 facing the outer surface of the permeation tube head 14 is attached to a soil barrier gauze 17. The stainless steel metal support mesh 16 fixed inside the circular through-hole 15 can support the soil barrier gauze 17 to prevent it from deforming. The soil barrier gauze 17 can prevent soil from entering the permeation tube head 14 through the circular through-hole 15 during steam sterilization.

[0024] A steam sterilization sealing mechanism 2 is fixed to the upper end face of the buried steam sterilization mechanism 24. The steam sterilization sealing mechanism 2 includes a U-shaped soil baffle 201 and a gear synchronous transmission mechanism. A sealing cover cloth receiving roller 213 is provided inside the U-shaped soil baffle 201 near the rear end face. A sealing cover cloth 214 is wrapped around the outer surface of the sealing cover cloth receiving roller 213, and a pull rod 217 is fixed to the inner side of the end of the sealing cover cloth 214 facing the stainless steel metal strip 21. The gear synchronous transmission mechanism can synchronously drive the pull rod 217 during the rotation of the sealing cover cloth receiving roller 213. Moving along the upper part of the stainless steel metal strip 21; the gear synchronous transmission mechanism includes a stepper motor 206, the output shaft of the stepper motor 206 is connected to a transmission shaft 207 via a coupling, a first bevel gear 208 is fixedly sleeved on the outer surface of the transmission shaft 207, the first bevel gear 208 meshes with a second bevel gear 209, the shaft of the second bevel gear 209 is connected to a gear shaft 210, a third bevel gear 211 is fixedly sleeved on the outer surface of the gear shaft 210 near the sealing cover cloth receiving roller 213, and the third bevel gear 211 meshes with a fixed... A fourth bevel gear 212 is fixedly mounted on the outer surface of the sealing cover cloth receiving roller 213. During steam sterilization via the buried steam sterilization mechanism 24, a stepper motor 206 is activated. The stepper motor 206 drives the connected transmission shaft 207 and the first bevel gear 208 fixedly mounted on the outer surface of the transmission shaft 207 to rotate. The rotating first bevel gear 208 drives the meshing second bevel gear 209 and the gear shaft 210 connected to the axis of the second bevel gear 209 to rotate together. When the gear shaft 210 rotates... The third bevel gear 211, which is fixedly sleeved on the outer surface of the gear shaft 210, and the fourth bevel gear 212, which meshes with the third bevel gear 211, will rotate accordingly. Finally, the rotating fourth bevel gear 212 can drive the sealing cover cloth collecting roller 213 connected to the shaft of the fourth bevel gear 212 to rotate. The rotating sealing cover cloth collecting roller 213 can continuously release the sealing cover cloth 214 wrapped around the outer surface of the sealing cover cloth collecting roller 213 or rewrap the released sealing cover cloth 214 around the outer surface of the sealing cover cloth collecting roller 213.

[0025] A threaded rod 215 is fixedly connected to the front end face of the gear shaft 210. An inner threaded sleeve 216 is installed on the outer surface of the threaded rod 215 at the position corresponding to the pull rod 217 through a threaded structure. The inner threaded sleeve 216 facing the pull rod 217 is fixed to the pull rod 217, and the front end of the pull rod 217 is slidably connected to the U-shaped soil baffle 201. During the rotation of the gear shaft 210, the threaded rod 215 fixed to it will rotate together. When the threaded rod 215 rotates, the inner threaded sleeve 216, which is installed on the outer surface of the threaded rod 215 through a threaded structure and fixed to the pull rod 217, will move along the threaded rod 215 under the drive of the threaded structure. At this time, the inner threaded sleeve 216 and the pull rod 217 gradually move forward. During the forward movement of the pull rod 217, the rotating sealing cover cloth receiving roller 213 will continuously release the sealing cover cloth 214 outward. As the lever 217 moves forward, it will pull the continuously released sealing cover 214 fixed to it to move forward together, thereby covering and sealing the soil between the L-shaped buried disinfection device shell 1 and the U-shaped soil baffle 201. The above technical solution can prevent the inhalation of toxic vapors by operators around the equipment when liquid agents such as chloropicrin, dazomet, and thiamethoxam are mixed into the steam disinfectant solution 7 to improve the disinfection effect of the equipment, thereby improving the safety when using the equipment. After the buried steam sterilization mechanism 24 has completed the sterilization process, the stepper motor 206 drives the connected transmission shaft 207 to rotate in the opposite direction, thereby gradually retracting the released sealing cover 214 and moving the pull rod 217 back to its original position.

[0026] The steam sterilization sealing mechanism 2 also includes a strip mounting platform 202. A steam discharge pipe 205 is provided on both sides above the strip mounting platform 202. The steam discharge pipe 205 facing the strip mounting platform 202 is connected to an exhaust fan 203 fixedly installed on the outer surface of the strip mounting platform 202. The lower end of the exhaust fan 203 is fixedly connected to a steam extraction pipe 204 that extends through the strip mounting platform 202 and the rear end of the U-shaped soil baffle 201 to the upper part of the rear end of the stainless steel metal strip 21. When the sterilization treatment of the buried steam sterilization mechanism 24 is completed, before starting the stepper motor 206 to rotate the transmission shaft 207 in the reverse direction, the exhaust fan 203 is started. The detoxifying steam is extracted through the steam extraction pipe 204 and transported to the interior of the toxic gas filtration equipment through the steam discharge pipe 205 to accelerate the dissipation of the sterilizing steam and prevent the residual sterilizing steam from being absorbed by the human body.

The steam exhaust pipe (205) facing the strip mounting platform (202) is connected to an exhaust fan (203) fixedly installed on the outer surface of the strip mounting platform (202). The lower end face of the exhaust fan (203) is fixedly connected to a steam extraction pipe (204) that extends through the strip mounting platform (202) and the rear end of the U-shaped soil baffle (201) to the upper part of the rear end of the stainless steel metal strip (21). A control panel (23) is fixedly installed on one side of the upper surface of the buried steam sterilization mechanism (24).

10. The method of using the soil disinfection apparatus for preventing root rot of ginseng roots according to claim 9, wherein the soil disinfection apparatus is used by: The method of use includes the following steps; Step A: When ginseng needs to be planted, fill the space between the upper surface of the L-shaped buried disinfection device shell (1) and the inner side of the U-shaped soil baffle (201), and then disinfect it. After 7-10 days of treatment, plant the ginseng in the disinfected soil. Step B: When soil disinfection is required, steam disinfectant (7) is filled into the evaporation tank (3) through the chemical addition tank (4). Then, the heating pipe (6) is started to heat the steam disinfectant (7) and turn it into disinfectant steam. While the heating pipe (6) is started to heat the steam disinfectant (7), the synchronous pushing mechanism is started to insert the permeation pipe head (14) with multiple circular through holes (15) on the outer surface into the soil. When the steam disinfectant (7) is turned into disinfectant steam by the heating pipe (6), it will flow upward and enter the soil through the permeation pipe head (14) and the circular through holes (15) on the outer surface of the permeation pipe head (14), thus performing steam disinfection treatment on the soil from the inside out. Step C: While the soil is being steam sterilized, the gear synchronous transmission mechanism in the steam sterilization sealing mechanism (2) is activated. The sealing cover (214) released by the continuously rotating sealing cover collection roller (213) is pulled outward through the pull rod (217) to seal the soil inside the U-shaped soil baffle (201).
