Description

Technical Field

[0001] This utility model relates to the field of soil aeration technology, and in particular to a soil aeration device for preventing plant root rot. Background Technology

[0002] In plant cultivation and agricultural production, soil aeration and the supply of nutrients and water directly affect root health. To prevent root rot, it is necessary to improve the anaerobic environment of the soil through aeration, while simultaneously supplementing water, fertilizer, or applying pesticides according to growth needs. However, current technologies often rely on separate equipment for aeration and liquid transport, which has significant limitations. Traditional soil aeration equipment (such as shallow aeration blowers and deep aeration needles) can only output gas, increasing oxygen content by increasing soil porosity, but cannot simultaneously complete liquid replenishment or disease control, requiring additional irrigation and fertilization devices, resulting in cumbersome operation. Meanwhile, conventional liquid delivery equipment (such as drip irrigation systems and manual fertilizer applicators) lacks targeted aeration pretreatment; direct injection of liquid into compacted soil can easily lead to localized waterlogging, exacerbating the risk of root hypoxia. Furthermore, pesticides or fertilizers are difficult to penetrate and absorb efficiently in an oxygen-deficient environment, resulting in low utilization rates.

[0003] In addition, separate operation of independent equipment requires multiple relocations of equipment and repeated positioning of soil areas, which not only increases labor costs and operation time, but may also damage the soil aggregate structure due to repeated soil entry operations, affecting the stability of the root growth environment.

[0004] There is an urgent need for a comprehensive device that can integrate gas and liquid dual-channel conveying functions and simplify the operation process. Utility Model Content

[0005] In order to overcome the shortcomings mentioned in the background art, this utility model provides a soil aeration device for preventing plant root rot.

[0006] The technical solution is as follows: A soil aeration device for preventing plant root rot includes a mobile vehicle, a blower, an air pipe, a solenoid valve, a hose, a sliding sleeve, an outer sleeve, an installation component, an aeration needle tube, a spring, an electric cylinder, and a handle. The top of the mobile vehicle is divided into front and rear installation positions by a partition. A blower is installed at the front installation position of the mobile vehicle. The top output end of the blower is connected to and connected to the air pipe. A solenoid valve is installed on the air pipe. The right end of the air pipe is connected to and connected to the hose. A sliding sleeve is fixedly connected to the outer side of the end of the hose. The outer sleeve is slidably connected to the inner side of the sliding sleeve. An aeration needle tube is slidably connected inside the outer sleeve. A through hole is opened on the upper side of the aeration needle tube, which is connected and communicates with the end of the hose. A spring is connected between the upper end of the aeration needle tube and the bottom of the inner side of the outer sleeve. The spring is sleeved on the outer side of the aeration needle tube. An installation component is connected to and connected to the top outer side of the outer sleeve. An electric cylinder is installed inside the installation component. The end of the extension rod of the electric cylinder is in contact with the top of the aeration needle tube. A handle is symmetrically connected to the upper outer side of the installation component. The outer sleeve, the installation component, and the auxiliary components constitute the aeration execution assembly.

[0007] Optionally, the lower end of the aeration needle tube is a pointed needle tip, and several oblique air outlets are evenly distributed around the side wall.

[0008] Optionally, it also includes an air seal, with a flared air seal connected to the outer side of the bottom end of the outer tube.

[0009] Optionally, it also includes a liquid pipe, a second solenoid valve, a water pump, a water tank, and a cover plate. A water tank is installed at the rear of the mobile vehicle, and a cover plate is rotatably connected to the top of the water tank via a hinge. A liquid pipe is connected to and communicates with the front of the water tank. The front end of the liquid pipe passes through the partition of the mobile vehicle and is connected to the air pipe. A second solenoid valve is installed in the middle of the liquid pipe. A water pump is installed at the rear of the top of the blower, and the water pump is connected to and communicates with the liquid pipe.

[0010] Optionally, the water tank can be made of a transparent material.

[0011] Optionally, the inner side of the cover is provided with an EPDM rubber sealing strip, and the contact surface with the water tank is provided with a concave-convex interlocking structure.

[0012] Optionally, it also includes a stirring rack, a bevel gear, and a rocker arm. The stirring rack is rotatably connected to the bottom of the water tank via a bearing, and the rocker arm is rotatably connected through the upper rear side of the water tank. The front end of the rocker arm is connected to a bevel gear, and the top of the stirring rack is also connected to a bevel gear. The two bevel gears mesh with each other.

[0013] Optionally, it also includes a semi-ring sleeve, with an elastic semi-ring sleeve connected to the upper right side of the water tank, and the aeration actuator is limited by the mounting piece snapping into the semi-ring sleeve.

[0014] Optionally, it also includes a winding reel, with the winding reel installed on the front side of the mobile vehicle partition, and the excess portion of the hose is orderly wound onto the winding reel.

[0015] Optionally, the aeration needle tube is made of 316L stainless steel, and the cone angle of the needle tip is 30°-45°.

[0016] The beneficial effects are: 1. The device integrates aeration, water replenishment, fertilization and pesticide application functions: Through the water tank and liquid pipe system, clean water, fertilizer solution or pesticide can be delivered simultaneously as needed, directly acting on the root area, realizing the integrated operation of "aeration + maintenance / disease control", reducing equipment handling and repetitive operations, and improving field management efficiency.

[0017] 2. By delivering air to the deep soil layers through aeration needles, combined with the sealed environment formed by the air seal, soil porosity and dissolved oxygen concentration around the roots can be rapidly increased, significantly improving aeration. At the same time, the airflow disturbance accelerates drainage, regulates the substrate moisture content to a reasonable range, and increases the soil redox potential, fundamentally breaking the anaerobic environment, inhibiting the reproduction of saprophytic bacteria, and effectively preventing plant root rot.

[0018] 3. The aeration actuator adopts an electric cylinder drive + spring reset structure, which can precisely control the depth of the aeration needle into the soil, ensuring that the needle enters the root concentration layer and avoids mechanical damage; the pointed needle end design facilitates rapid soil entry, and the slanted air outlet reduces soil particle blockage and improves operational stability.

Detailed Implementation

[0026] Example: A soil aeration device for preventing root rot in plants, such as... Figures 1-5 As shown, the assembly includes a mobile cart 1, a blower 2, an air pipe 3, a solenoid valve 4, a hose 5, a sliding sleeve 6, an outer sleeve 7, a mounting component 71, an aeration needle tube 8, a spring 9, an electric cylinder 10, a handle 11, an air seal cover 12, and a winding reel 19. The top of the mobile cart 1 is divided into front and rear mounting positions by a partition. The blower 2 is installed at the front mounting position of the mobile cart 1. The top output end of the blower 2 is connected to and connected to the air pipe 3. A solenoid valve 4 is installed on the flange of the air pipe 3. The right end of the air pipe 3 is connected to and connected to the hose 5. A sliding sleeve 6 is fixedly connected to the outer side of the end of the hose 5. The outer sleeve 7 is slidably connected to the inner side of the sliding sleeve 6. An aeration needle tube 8 is slidably connected to the inner side of the outer sleeve 7 along the axial direction. A through hole is opened on the upper side of the aeration needle tube 8, which is connected and communicates with the end of the hose 5. A spring 9 is connected between the upper end of the aeration needle tube 8 and the bottom of the inner side of the outer sleeve 7. The spring 9 is sleeved on the outer side of the aeration needle tube 8. The lower end of the aeration needle tube 8 is a pointed needle end, and the side wall is evenly distributed circumferentially. Several oblique air outlets are arranged to achieve dual-channel gas-liquid output. The aeration needle tube 8 is made of 316L stainless steel (to improve strength). The cone angle of the needle tip is 30°-45° to ensure smooth penetration into the soil. The outer end of the outer tube 7 is connected to a trumpet-shaped air seal cover 12. The top outer side of the outer tube 7 is connected to and connected to the mounting part 71. The mounting part 71 is bolted with an electric cylinder 10. The end of the telescopic rod of the electric cylinder 10 is in contact with the top of the aeration needle tube 8. The upper outer side of the mounting part 71 is symmetrically welded with handles 11. The outer tube 7, the mounting part 71 and the auxiliary parts constitute an independently operable aeration actuator. The front side of the partition of the mobile vehicle 1 is equipped with a winding reel 19. The excess part of the hose 5 can be wound orderly on the winding reel 19, which can not only avoid the hose 5 from being messy and worn, but also save space and facilitate storage and organization. When using, the hose 5 can be loosened from the winding reel 19, which can flexibly adapt to different working distances.

[0027] When performing soil aeration treatment to prevent root rot in plants, first push the device to the designated location. Then, the operator holds handle 11 and aligns the aeration actuator with the target soil surface. The horn-shaped air seal 12 fits against the soil surface to form an annular sealing cavity, providing a stable and sealed environment for the aeration process. Next, start the electric cylinder 10. Its extension rod pushes the aeration needle tube 8 downward at a feed speed of 50mm / s. The spring 9 compresses and stores energy synchronously. During this process, the aeration needle tube 8 quickly penetrates the soil with its pointed end. When the extension rod of the electric cylinder 10 shortens and resets, the aeration needle tube 8 moves upward and resets under the reset action of the spring 9. This process can be repeated through jog control mode until the tip of the aeration needle tube 8 enters the root concentration layer. When the aeration needle tube 8 moves, the sliding sleeve 6 slides synchronously to maintain the communication between the hose 5 and the inside of the aeration needle tube 8. After reaching the appropriate depth, the extension rod of the electric cylinder 10 remains extended, and the aeration needle tube 8 is stabilized in this position. Then, open the solenoid valve 4 and start the blower 2. The blower 2 draws out external... Air is delivered through the air tube 3 to the hose 5, and then into the aeration needle tube 8. It diffuses radially into the soil through the air outlets on the aeration needle tube 8, forming an aeration zone with a diameter ≥20cm. This increases soil porosity by 15-25%, raising the dissolved oxygen concentration around the roots from 2-4 mg / L to 8-12 mg / L, improving soil aeration, and supporting root aerobic respiration. During this process, oxygen infiltration increases the intensity of root aerobic respiration by 40-60%, and increases ATP production to promote nutrient absorption. At the same time, the soil redox potential rises to 300-500mV, inhibiting the anaerobic metabolism of saprophytic bacteria. The airflow disturbance can also accelerate the drainage of accumulated water and reduce the substrate moisture content to 60-70% of the field capacity. This breaks the anaerobic environment of the soil from multiple dimensions. After aeration, the blower 2 is turned off, and the telescopic rod of the electric cylinder 10 is controlled to shorten and reset. The aeration needle tube 8 moves upward and resets under the elastic potential energy of the spring 9, driving the sliding sleeve 6 to move upward synchronously. Following the above operation, the soil in other areas can be aerated.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, it also includes a liquid pipe 31, a second solenoid valve 41, a water pump 13, a water tank 14, and a cover plate 15. The water tank 14 is bolted to the rear mounting position of the mobile vehicle 1. The water tank 14 is made of transparent material, which makes it easy to see the amount of liquid stored inside. The top of the water tank 14 is connected to the cover plate 15 by a hinge. The inner side of the cover plate 15 is provided with an EPDM rubber sealing strip. The contact surface with the water tank 14 is provided with a concave-convex interlocking structure to form a flip-top sealing structure. When the cover plate 15 is opened, clean water, fertilizer solution, or medicine can be easily injected. When closed, it can achieve a seal to prevent liquid from overflowing or impurities from falling in. The front side of the water tank 14 is connected to and connected to the liquid pipe 31. The front end of the liquid pipe 31 passes through the partition of the mobile vehicle 1 and is connected to the air pipe 3. The flange in the middle of the liquid pipe 31 is equipped with a second solenoid valve 41. The water pump 13 is installed on the rear side of the top of the fan 2. The water pump 13 is connected to and connected to the liquid pipe 31.

[0029] In practical applications, the appropriate liquid can be injected into the water tank 14 according to the soil conditions: clean water is used to replenish soil moisture, fertilizer solution can be used for precise fertilization, and pesticides can be used to treat root problems (acting directly on damaged parts to reduce the spread of diseases). After oxygen is introduced into the soil, the solenoid valve 1 4 can be closed first (to prevent gas from mixing into the liquid delivery path), and then the solenoid valve 2 41 can be opened. Using the operation of injecting air earlier, the aeration needle tube 8 of the aeration actuator can be kept in a state of being deeply embedded in the soil. Then, the water pump 13 can be started, and the liquid in the water tank 14 can be delivered to the aeration needle tube 8 through the liquid pipe 31 and the hose 5. Finally, it can penetrate into the soil through the air outlet on the aeration needle tube 8 and reach the roots. After the liquid delivery is completed, the water pump 13 and the solenoid valve 2 41 can be closed, and finally the aeration actuator can be lifted and reset.

[0030] like Figure 5 and Figure 6 As shown in the figure, it also includes a mixing frame 16, a bevel gear 17, and a rocker arm 18. The mixing frame 16 is rotatably connected to the bottom of the water tank 14 via a bearing. The rocker arm 18 is rotatably connected through the upper rear side of the water tank 14. The front end of the rocker arm 18 is keyed to the bevel gear 17, and the top end of the mixing frame 16 is also keyed to the bevel gear 17. The two bevel gears 17 mesh with each other. When fertilizer solution or pesticide is stored in the water tank 14, the rocker arm 18 can be manually cranked before the liquid is injected into the soil. The bevel gear 17 drives the mixing frame 16 to rotate, so that the liquid is fully mixed and uniform. This ensures that the fertilizer is fully dissolved, the pesticide concentration is consistent, and the activity of the liquid is maintained, thereby improving the effect.

[0031] like Figure 5 As shown, it also includes a semi-ring sleeve 20. The upper right side of the water tank 14 is connected to the elastic semi-ring sleeve 20. The aeration actuator can be fixedly positioned by the mounting piece 71 being inserted into the semi-ring sleeve 20 to prevent shaking when idle. When in use, the aeration actuator can be easily removed by pulling it outward with the elastic deformation of the semi-ring sleeve 20. The operation is convenient.
