Abstract

This invention belongs to the field of agricultural machinery technology, and specifically relates to a spray-explosion type deep loosening and deep application seeding engineering equipment and its operation method. The spray-explosion type deep loosening and deep application seeding engineering equipment includes a frame with wheels, a spray-explosion system, a feeding system, a deep application rod, and a seeding device. The spray-explosion system generates compressed air shock waves to create a spray explosion in the soil. The feeding system sprays liquid fertilizer into the soil under positive pressure through the deep application rod. By using the feeding system and deep application rod to spray liquid fertilizer under positive pressure, this invention enables loosening and fertilization of the entire area covering root growth. Furthermore, immediately after the soil is loosened by the gas impact, as the equipment moves, the feeding system and deep application rod immediately spray the liquid fertilizer under positive pressure, evenly distributing the material into the cracks of the loosened soil. Since gaps remain between the soil particles that have not yet returned to their original positions, the liquid fertilizer can spread to a more distant area through these gaps.

Description

Technical Field

[0001] This invention belongs to the field of agricultural machinery technology, and specifically relates to a spray-type deep tillage and deep application seeding engineering equipment and its operation method. Background Technology

[0002] Agricultural planting involves many steps, including loosening the soil, tilling, and fertilizing. Currently, these steps require the use of soil loosening machines, seeders, and fertilizer applicators, respectively, resulting in high costs, especially in mountainous and hilly areas where efficiency is low. Therefore, there is an urgent need for a device that is both highly efficient and cost-effective in agricultural planting to solve these technical problems.

[0003] Chinese patent CN205093137U discloses a sowing and fertilizing integrated machine, including a frame, wheels, and axles. The wheels are installed at both ends of the axles, and the frame is installed on the axles. The rear of the frame is provided with a sowing and fertilizing mechanism and a support. The sowing and fertilizing mechanism includes a seed hopper and a fertilizer hopper. The seed hopper and fertilizer hopper are connected to a mixing hopper through a mixing pipe. The bottom of the mixing hopper is provided with a discharge port, which is connected to a sowing rod through a discharge pipe. The support is provided with a sliding groove, and the sowing rod is installed in the sliding groove.

[0004] This device, by setting up a seed hopper, a fertilizer hopper, and a mixing hopper, enables the pre-mixing of seeds and fertilizers before sowing them together in the field; however, the device has the following problems: it is difficult to ensure uniform fertilization and the seeds do not absorb the fertilizer well. Summary of the Invention

[0005] This invention provides a spray-type deep tillage and deep application seeding engineering equipment and its operation method, which can solve the problem of uneven fertilization.

[0006] To achieve the above objectives, this solution provides a spray-type deep tillage and deep application seeding engineering equipment, including a frame equipped with wheels, a spray-type system, a feeding system, a deep application rod, and a seeding device. The spray-type system is used to generate compressed air shock waves and create a spray in the soil.

[0007] The deep application rod is provided with an application channel. The outlet of the feeding system is connected to the application channel in the deep application rod through an outlet pipe. The lower end of the deep application rod is provided with at least one outlet hole connected to the application channel. The upper end of the deep application rod and the feeding system are connected to the vehicle frame. The feeding system is used to spray liquid fertilizer into the soil through positive pressure via the deep application rod.

[0008] The sowing device includes a seed box and a sowing rod. The sowing rod has a sowing channel that runs through its upper and lower ends. The seed box is mounted on a frame. The sowing rod is connected to the seed box. The sowing rod is located at the rear end of the deep spraying rod. The length of the sowing rod matches the vertical length of the deep spraying rod. The deep spraying rod has triangular protruding wings on its left and right sides, and the discharge hole passes through the wings.

[0009] The principle of this scheme is as follows: First, the vehicle frame is placed on the soil via the wheels. Then, the deep-plowing rod is placed within 60cm of the soil, with the planting depth of the rod being 2-5cm. The feeding system contains liquid materials, solid-liquid mixtures, or powdery materials. The vehicle frame is then moved forward by its own power or an external drive mechanism. During this forward movement, the triangular protruding wings connected to the deep-plowing rod form a seal between the spray holes and the original soil area. The spray system generates compressed air shock waves, creating a spray effect in the soil, loosening the soil, breaking up soil compaction, and reducing damage to the deep-plowing rod. This system expands soil porosity. As the equipment moves rapidly, after the spraying and before the soil has fully recovered its original position, the feeding system sprays liquid fertilizer through the application holes connected to the deep application rod under positive pressure. This ensures the liquid fertilizer is evenly distributed in the gaps between the loosened soil layers. Simultaneously, seeds from the seed box enter the sowing channel of the sowing rod and then fall into the soil. Once the seeds in the soil germinate, they can absorb the relatively evenly distributed fertilizer. This achieves a combined operation of moving, spraying and deep loosening, spraying and deep application, and sowing simultaneously. By adding wings, the position of the discharge hole can be widened, allowing for a larger spraying area.

[0010] The beneficial effects of this plan are:

[0011] 1. This plan first uses a spraying and blasting system to deeply loosen the soil, breaking up soil compaction and creating cracks between soil particles. Then, a feeding system sprays fertilizer under positive pressure into the loosened soil, ensuring that the fertilizer is evenly distributed throughout the soil and does not accumulate in the furrows formed during the deep application process, thus preventing seedling burn. Furthermore, when seeds are sown in the soil, as they germinate, their roots will extend into the fertilized soil, allowing for better absorption of fertilizer and facilitating seed germination and seedling growth.

[0012] 2. This solution sprays fertilizer into the loosened soil, preventing it from dispersing into the air and causing fertilizer loss and air pollution. In the event of heavy rain or strong winds, it will not be washed away by surface runoff or blown away, causing water and wind erosion. After the plant roots absorb the fertilizer, they take root in the soil, preventing the crop roots from floating up. The crop roots' ability to absorb nutrients and resist adverse environmental conditions is improved, reducing the impact of natural disasters such as diseases, pests, drought, and extreme weather.

[0013] 3. By using the feeding system and deep application rod of this solution to spray liquid fertilizers under positive pressure, it is possible to loosen and fertilize the entire area covering the root system. Moreover, after the soil has been loosened by the air shock wave, as the equipment moves quickly, the feeding system and deep application rod will immediately spray the liquid fertilizers under positive pressure, so that the fertilizer is evenly sprayed on the loosened soil. At this time, there are still gaps between the soil that has not yet returned to its original position, so the liquid fertilizers can quickly spread to a farther place through the gaps, making the fertilization area larger and more uniform.

[0014] 4. This method combines walking, loosening the soil, fertilizing, and sowing simultaneously, improving the efficiency of all three processes. The working depth is within 60cm. Therefore, this method is suitable for crops with root systems within 60cm, including field crops such as wheat, corn, soybeans, and cotton, as well as orchards, grasslands, pastures, medicinal herbs, and tea gardens. The fact that the surface soil is not disturbed is significant in windy and arid northern regions, reducing dust sources and soil erosion. Not disturbing the surface also reduces the surface area for evaporation, lowering evaporation rates and promoting soil moisture and nutrient retention. Through deep loosening by spraying, all areas with crop root systems are thoroughly loosened. The spraying also breaks up soil capillaries, reducing capillary evaporation, helping to retain moisture, and preventing soil salinization. The material is applied more evenly. Under the action of compressed air, the material is evenly distributed in the middle and lower layers of the soil root system, reducing air evaporation and loss, and inducing the roots to extend into deeper soil layers, increasing the root distribution range, making full use of deep soil nutrients and water, and improving the plant's stress resistance, thereby improving the input-output ratio. Energy consumption is low because it explodes in the lower soil layer without strong mechanical resistance, requiring much less power compared to traditional moldboard plows and rotary tillers.

[0015] 5. Wide range of applications: It can be applied to fields, forests, grasslands, deserts, tea gardens, pastures, and other scenarios. It can also be used to fertilize organic waste such as biogas slurry and return it to the fields. A wide range of materials can be selected for application, including chemical fertilizers, organic fertilizers, biogas slurry, organic solid particles, organic waste slurry, mineral powder, etc.

[0016] 6. This equipment and operating method significantly improves agricultural production efficiency, comprehensively enhances soil aeration, rapidly forms soil aggregate structure, and improves soil ecology and chemical state. The effects are rapid, covering most of the crop growth area, and comprehensively improves the soil environment provided by the current season's crops, thus achieving high yields. This solution can place large amounts of organic waste, mineral elements, and beneficial microorganisms into the feeding system for returning to the field, improving soil ecology, refining the soil, and enhancing basic soil fertility, achieving the goal of soil nourishment. Year after year, various soil indicators continuously improve, the land becomes increasingly fertile with cultivation, and even pollutants such as manure are reused. The final links in agriculture related to crop-livestock cycles, carbon-oxygen cycles, and nitrogen-oxygen cycles are opened up, realizing a large-scale cycle of agriculture, forestry, animal husbandry, and fisheries.

[0017] Furthermore, the explosion system includes an explosion-prone deep loosening rod, which has an explosion-prone channel inside. The lower end of the explosion-prone deep loosening rod has at least one explosion hole, which is not oriented downwards. The upper end of the explosion-prone channel is connected to the air outlet of the explosion-prone system via a pipe, and the lower end of the explosion-prone channel is connected to the explosion hole. The upper end of the explosion-prone deep loosening rod and the explosion-prone system are connected to the vehicle frame. The explosion-prone system is used to generate compressed air shock waves and form explosions through the explosion-prone deep loosening rod. The deep loosening rod is fixedly connected to the explosion-prone deep loosening rod. Both the explosion-prone deep loosening rod and the deep loosening rod are curved. The explosion-prone deep loosening rod has triangular protruding wings on its left and right sides. The explosion hole penetrates the wings, and the outer wheel of the wing is aligned with the direction of travel of the equipment.

[0018] Beneficial effects: During operation, the spraying deep loosening rod, deep application rod, and seeding rod are all placed in the soil. The triangular protruding wings connected to the spraying deep loosening rod maintain a seal between the spraying holes and the soil during forward movement. The spraying system generates compressed air shock waves, which are then sprayed into the soil through the spraying deep loosening rod. The deep application rod then applies fertilizer, and the seeds in the seed box enter the seeding channel of the seeding rod and are then sown at an appropriate depth in the soil.

[0019] Furthermore, both the spraying and slack rod and the deep application rod are slidably connected to the vehicle frame at the front and rear. The vehicle frame is equipped with a high-frequency vibrator that reciprocates linearly along the direction of equipment travel. The high-frequency vibrator is used to generate high-frequency vibrations that act on the spraying and slack rod.

[0020] Beneficial effects: During the process of the self-driving force or drive mechanism pulling the frame forward, the high-frequency vibrator continuously generates high-frequency vibrations that act on the spraying and blasting deep loosening rod. This causes the spraying and blasting deep loosening rod to vibrate the soil at high frequency, resulting in soil liquefaction. This reduces the resistance encountered by the spraying and blasting deep loosening rod as it moves forward in the soil, allowing it to move faster. At the same time, during the high-frequency vibration, the spraying and blasting system performs spraying and blasting. The system generates compressed air shock waves that are then sprayed into the soil through the spraying and blasting deep loosening rod, loosening the soil. Then, the feeding system sprays liquid fertilizers through the deep application rod under positive pressure, ensuring that the liquid fertilizers are evenly sprayed into the pores between the loosened soil that has not yet returned to its original position. The spraying and blasting deep application under high-frequency vibration reduces the resistance to movement and improves work efficiency.

[0021] Furthermore, the high-frequency vibrator is connected to the vehicle frame, and the high-frequency vibrator is fixedly connected to the deep-applied rod.

[0022] Beneficial effects, facilitating the direct application of high-frequency vibrators to the deep-penetration spraying rod.

[0023] Furthermore, the explosion system also includes an air compressor, an energy storage tank, and an explosion canister with a quick exhaust valve. The energy storage tank is connected to the air compressor and the explosion canister via pipes, and the outlet of the explosion canister is connected to the upper end of the explosion channel via a hose.

[0024] Beneficial effects: The energy storage tank serves as a buffer and storage for compressed air, with its pressure and capacity matched to the exhaust pressure and volume of the air compressor. The explosion tank instantly releases compressed air at a certain pressure and volume, which enters the soil through the explosion deep loosening rod, generating shock waves and gas expansion to loosen the soil, break up compacted clumps, and loosen a wider area of ​​soil.

[0025] Furthermore, the feeding system includes a feeding box, a hydraulic pump, an inlet pipe, and an outlet pipe. The inlet of the hydraulic pump is connected to the feeding box through the inlet pipe, and the outlet of the hydraulic pump is connected to the feeding channel at the upper end of the deep application rod through the outlet pipe. The outlet pipe is a flexible hose. The inlet pipe is equipped with an inlet check valve, and the outlet pipe is equipped with an outlet check valve. The feeding box contains liquid materials, solid-liquid mixtures, or powder materials. Solid-liquid mixtures and powder materials need to have good flowability. The hydraulic pump can also be a discharge valve.

[0026] Beneficial effects: The hydraulic pump can spray liquid fertilizer evenly onto the loosened soil at a certain pressure, resulting in a larger, more uniform, and faster area for deep soil remediation and improvement.

[0027] Furthermore, the upper ends of the spraying deep loosening rod and the deep application rod are inclined, and the upper ends of the spraying deep loosening rod and the deep application rod are provided with telescopic devices that can adjust the deep loosening and deep application depth. The adjustment length of the telescopic device is less than 60cm.

[0028] Beneficial effects: Facilitates deep loosening and deep application of soil within a depth of 60cm.

[0029] Furthermore, the lower end of the spray-blown deep loosening rod is detachably connected to a spray-blown deep loosening head.

[0030] Beneficial effects include reducing the processing difficulty of deep loosening rods and saving costs.

[0031] Furthermore, the outer periphery of the deep tapping head is cone-shaped, and the deep tapping head extends outward to form radial triangular protrusions.

[0032] Beneficial effects: The radial triangular protrusions can reduce airflow resistance and facilitate the forward movement of the deep pine cone.

[0033] Furthermore, the end of the deep loosening head is provided with a first conical diverter, the tip of which faces the air inlet of the deep loosening rod. The first conical diverter is matched with the detonation channel and the detonation hole respectively. The outer end of the deep loosening rod is provided with an outer ring body, which is provided with an internal thread or a retaining groove. The end of the deep loosening head is provided with an external thread or a retaining groove that matches the internal thread. There are multiple detonation holes, which are distributed along the left and right sides and the top of the deep loosening rod.

[0034] Beneficial effects: Due to the high pressure and high velocity of the high-pressure gas injected into the deep loosening rod, the high-pressure airflow can easily flow to the end of the rod, resulting in insufficient air supply to the injection holes on the side wall. Therefore, the first conical distributor in the above-mentioned structure can evenly distribute the high-pressure air in the deep loosening rod to each injection hole, ensuring the uniformity and effectiveness of the final soil loosening. The deep loosening head is connected to the deep loosening rod by a spiral or snap-fit ​​connection, facilitating disassembly and installation. Furthermore, multiple injection holes can spray the soil on the left and right sides and top, resulting in a wider soil loosening coverage area.

[0035] Furthermore, a second conical diverter is provided at the end of the deep application rod, with the tip of the second conical diverter facing the feed inlet of the deep application rod, and the second conical diverter is matched with the application channel and the discharge hole respectively.

[0036] Beneficial effects: It avoids fertilizer concentration at the inner end of the deep application rod. By setting the function of the second conical diverter, the positive pressure material in the deep application rod can be evenly distributed to each discharge hole, ensuring the balance and effect of final fertilization.

[0037] Furthermore, the spraying and deep loosening rod and the deep application rod are provided with triangular protruding wings on the left and right sides, and the spraying hole and the discharge hole both pass through the wings, and the outer wheel of the wing is in the same direction as the equipment's travel.

[0038] Beneficial effects: By setting up wings, the spray holes on the wings can form a better seal with the soil, and the spray and fertilization distance can be longer. Without wings, the compressed air shock wave will spray directly at the side wall of the deep loosening rod. However, with wings, the compressed air shock wave will travel a distance of the width of the wings before spraying, resulting in a longer spray distance and a wider deep loosening range. Fertilization follows the same principle.

[0039] Furthermore, the blasting deep loosening rod is equipped with a soil-breaking blade, and the cutting edge of the soil-breaking blade is located in the direction of the vehicle frame's forward movement.

[0040] Beneficial effects: The soil liquefaction effect created by the soil breaking blades and high-frequency vibrators can significantly reduce the resistance of the deep loosening rod, making its movement smoother.

[0041] Furthermore, a pressure transmitter and a gas-filling solenoid valve are installed on the pipeline between the energy storage tank and the explosion-proof tank. The explosion-proof tank is electrically connected to the explosion-proof solenoid valve, and the pressure transmitter is located between the explosion-proof solenoid valve and the explosion-proof tank.

[0042] Beneficial effects: The compressed air from the air compressor enters the energy storage tank. The pressure of the compressed air in the energy storage tank is regulated by the pressure transmitter to provide the appropriate detonation pressure to the detonation tank. The detonation solenoid valve is a major component of the detonation system and is used to open and close the detonation tank.

[0043] Furthermore, the traveling wheels include front wheels and rear wheels, with two front wheels and two rear wheels, symmetrically arranged along the center line of the vehicle frame. It also includes a traveling compaction wheel, the width of which matches the range of the upward blasting.

[0044] Beneficial effects: The device uses wheels to facilitate better movement of the frame, and the center line of the compaction wheel is located above the center line of the blast hole, which can prevent the upward blasting airflow from breaking up the soil and play a compaction role, thereby making the upward blasting deep loosening range wider.

[0045] Furthermore, the deep-applying rod is provided with multiple discharge holes, which are located on the left and right sides of the deep-applying rod.

[0046] Beneficial effects: The discharge holes on both sides of the deep application rod can spray materials to both sides of the soil under positive pressure, making the material spread over a wider range.

[0047] Furthermore, it also includes a drive mechanism, which is detachably connected to the frame. The drive mechanism is equipped with a hook, and the walking frame is equipped with a hook ring that matches the hook.

[0048] Beneficial effects: Facilitates the installation and disassembly of the drive mechanism and frame.

[0049] Furthermore, the frame is also hinged with a flat floor, the seeding rod is located at the rear end of the flat floor, the flat floor matches the ground surface, and the flat floor is provided with two limiting blocks, the distance between the two limiting blocks gradually decreases from top to bottom, and the hinge is preferably a spring hinge.

[0050] Beneficial effects: The flat floor is used to level the trenches formed by the spraying and deep loosening rods and deep application rods during the spraying and fertilizing process. The two limiting blocks are used to refill the soil pushed away by the soil-breaking blades into the trenches and compact it. At the same time, it can also prevent fertilizer from volatilizing into the air and causing waste. Seeds and seedlings can be sown or planted on loose and fertilized soil using no-till seeding devices or transplanting devices.

[0051] Furthermore, a ball valve is provided on the feed pipe.

[0052] Beneficial effect: Facilitates opening and closing of the feed box.

[0053] Furthermore, a method for deep loosening and deep application of seeds using a spray-blasting technique is also disclosed, employing the aforementioned device and comprising the following steps:

[0054] Step S1: Prepare fertilizer by mixing the prepared liquid material, solid-liquid mixture, or powder material according to the soil test formula.

[0055] Step S2: Set parameters, such as the penetration depth, blasting pressure, and feeding speed, according to the soil conditions to be operated.

[0056] Step S3: Operation preparation. Load the liquid fertilizer into the feeding box, fill the seed box with seeds, connect the drive mechanism to the frame, and set the speed of the drive mechanism.

[0057] Step S4: Loosening the soil and fertilizing. The equipment moves while spraying and loosening the soil, fertilizing and sowing seeds. Attached Figure Description

[0066] Example 1 is attached. Figure 1 As shown,

[0067] A spray-explosion type deep tillage and deep application seeding engineering equipment includes a frame 1 with wheels, a spray-explosion system, a feeding system, a deep application rod 3, and a seeding device. The spray-explosion system generates compressed air and creates a spray-explosion in the soil.

[0068] The deep application rod 3 is provided with a material application channel 7. The outlet of the material supply system is connected to the material application channel 7 at the upper end of the deep application rod 3 through a material application pipe. The lower end of the deep application rod 3 is provided with at least one material outlet 8 connected to the material application channel 7. In this embodiment, the deep application rod 3 is provided with two material outlets 8, which are located on the left and right sides of the deep application rod 3 respectively.

[0069] The feeding system includes a feeding box 15, a hydraulic pump 16, an inlet pipe, and an outlet pipe. The inlet of the hydraulic pump 16 is connected to the feeding box 15 through the inlet pipe, and the outlet of the hydraulic pump 16 is connected to the feeding channel 7 at the upper end of the deep application rod 3 through the outlet pipe. The outlet pipe is a flexible hose. The inlet pipe is equipped with an inlet check valve, and the outlet pipe is equipped with an outlet check valve. The feeding box 15 contains liquid materials, solid-liquid mixtures, or powder materials. Solid-liquid mixtures and powder materials require good flowability.

[0070] The hydraulic pump 16 can spray liquid fertilizer evenly onto the loosened soil at a certain pressure, resulting in a larger and more uniform area for deep soil remediation and improvement. A ball valve 6 is installed on the feed pipe for easy opening and closing of the feed box 15.

[0071] The upper end of the deep application rod 3 and the feeding system are connected to the frame 1. The feeding system is used to spray liquid fertilizer into the soil under positive pressure through the deep application rod 3. The sowing device includes a seed box 10 and a sowing rod 11. The sowing rod 11 has a sowing channel that runs through its upper and lower ends. The seed box 10 is detachably mounted on the frame 1. The sowing rod 11 is connected to the seed box 10 through a hose with an electric valve. The sowing rod 11 is located at the rear end of the deep application rod 3, and the length of the sowing rod 11 matches the vertical length of the deep application rod 3.

[0072] As attached Figure 2-3 As shown,

[0073] The spraying and blasting system includes a spraying and blasting deep loosening rod 2, which has a spraying and blasting channel 5 inside. At least one spraying hole 4 is located at the lower end of the spraying and blasting deep loosening rod 2. In this embodiment, there are three spraying holes 4, distributed on the left, right, and upper sides of the spraying and blasting deep loosening rod 2. After the soil is loosened by the spraying and blasting of the three spraying holes 4 on the three sides of the deep loosening rod 3, the discharge holes 8 on the left and right sides of the deep loosening rod 3 can spray material at high pressure to both sides of the soil, resulting in a wider diffusion range of the material. Consequently, the resistance encountered during the deep application of fertilizer is reduced, making it easier for the fertilizer to enter the loosened soil.

[0074] The upper end of the spraying channel 5 is connected to the air outlet of the spraying system via a pipe, and the lower end of the spraying channel 5 is connected to the spraying hole 4. The upper end of the spraying deep loosening rod 2 and the spraying system are connected to the frame 1. The spraying system is used to generate compressed air and form a spray explosion through the spraying deep loosening rod 2. The deep application rod 3 is fixedly connected to the spraying deep loosening rod 2. Both the spraying deep loosening rod 2 and the deep application rod 3 are curved, and their lower ends are horizontally set. During operation, the spraying deep loosening rod 2, the deep application rod 3, and the sowing rod 11 are all placed in the soil. The spraying system is used to generate compressed air and form a spray explosion in the soil through the spraying deep loosening rod 2. Then, the deep application rod 3 applies fertilizer. The seeds in the seed box enter the sowing channel of the sowing rod 11 and then come out from the sowing channel and are sown in the soil at an appropriate depth.

[0075] The explosion system also includes an air compressor 12, an energy storage tank 13, and an explosion canister 14. The energy storage tank 13 is connected to the air compressor 12 and the explosion canister 14 through pipes, and the outlet of the explosion canister 14 is connected to the upper end of the explosion channel 5 through a hose.

[0076] The energy storage tank 13 is used for compressed air buffering and storage, and its pressure and capacity are matched with the exhaust pressure and volume of the air compressor. The explosion tank 14 releases a certain pressure and volume of compressed air instantly, which enters the soil through the explosion deep loosening rod 2, generating shock waves and gas expansion to loosen the soil, break up compacted clumps, and loosen the soil over a wider area.

[0077] A pressure transmitter 27 and a gas charging solenoid valve 28 are installed on the pipeline between the energy storage tank 13 and the explosion tank 14. The explosion tank 14 is electrically connected to the explosion solenoid valve 29, and the pressure transmitter 27 is located between the explosion solenoid valve 29 and the explosion tank 14.

[0078] The compressed air from the air compressor 12 enters the energy storage tank 13. The pressure of the compressed air in the energy storage tank 13 is regulated by the pressure transmitter 27 to provide a suitable detonation pressure to the detonation canister 14. The charging solenoid valve 28 prevents the compressed air from flowing back, and the detonation solenoid valve 29 is used to open and close the detonation canister 14. An oil-water separator 18 is connected to the pipeline between the air compressor 12 and the energy storage tank 13. The oil-water separator 18 is used to separate moisture from the air compressor 12.

[0079] Both the blasting deep loosening rod 2 and the deep application rod 3 are slidably connected to the frame 1 at the front and rear. The frame 1 is provided with a sliding groove. Both the blasting deep loosening rod 2 and the deep application rod 3 are provided with sliders that match the sliding groove. The frame 1 is provided with a high-frequency vibrator 9, which is used to generate high-frequency vibrations that act on the blasting deep loosening rod 2.

[0080] The soil area that has not been sprayed, deep loosened and applied is called the original soil area. The purpose of the original soil area is to seal the spray holes at the front of the triangular protrusion-shaped wing, so as to facilitate the subsequent spraying.

[0081] The soil area where spraying and deep loosening and deep application are being carried out is the deep loosening and deep application zone. The deep loosening and deep application zone is a functional area for realizing dynamic soil spraying and deep loosening and material spraying and deep application. The addition of a compaction wheel allows the spraying and deep loosening range and the material deep application range to be expanded in a controllable manner.

[0082] The soil area that has been sprayed and deep loosened is called the subsidence zone. The subsidence zone is the deep loosening compensation zone and the functional realization zone. The fertilization compensation zone is where the soil after the wing lift deep loosening has only undergone appropriate deep loosening and has not been fully sprayed and deep-applied. Here, an external positive pressure deep loosening material pipeline opening can be added to allow the material to be suspended and sprayed and deep-applied to the cracks in the subsided deep loosened soil. The functional realization zone can be sprayed and deep-applied to supplement and add various types of materials related to planting or soil repair, so as to facilitate deep soil operations such as watering, water retention, sowing, transplanting, supplementing nutrients, and controlling soil diseases and pests.

[0083] The high-frequency vibrator 9 is connected to the frame 1 and fixedly connected to the deep-applying rod 3. This allows the high-frequency vibrator 9 to directly act on the deep-applying rod 3.

[0084] The upper ends of the spraying deep loosening rod 2 and the deep application rod 3 are inclined, and the length of the upper ends of the spraying deep loosening rod 2 and the deep application rod 3 is greater than 60cm.

[0085] It facilitates deep loosening and deep application of soil within a depth of 60cm.

[0086] The lower end of the deep loosening rod 2 is detachably connected to a deep loosening head 21. This reduces the processing difficulty of the deep loosening rod 2 and saves costs. The maximum diameter of the deep loosening head 21 is less than or equal to the diameter of the deep loosening rod 2.

[0087] The outer periphery of the deep-powdering nozzle 21 is cone-shaped, and radial triangular protrusions 26 extend outward from the nozzle. These radial triangular protrusions 26 reduce airflow resistance, facilitating the forward movement of the deep-powdering nozzle. The end of the deep loosening head 21 is provided with a first conical diverter 22, the tip of which faces the air inlet of the deep loosening rod 2. The first conical diverter 22 is matched with the detonation channel 5 and the detonation hole 4 respectively. The outer end of the deep loosening rod 2 is provided with an outer ring body 23, which has an internal thread. The end of the deep loosening head 21 is provided with an external thread or a retainer that matches the internal thread. Because the high pressure and flow rate of the high-pressure gas injected into the deep loosening rod 2 are high, it is easy for the high-pressure airflow to flow to the end of the deep loosening rod 2, resulting in insufficient air in the injection holes on the side wall of the deep loosening rod 2. Therefore, through the action of the first conical diverter 22 of the above structure, the high-pressure air in the deep loosening rod 2 can be evenly distributed to each injection hole, ensuring the final soil loosening balance and loosening effect. The spraying and deep loosening head 21 is spirally connected to the spraying and deep loosening rod 2, which is convenient for disassembly and installation. The multiple spraying holes 4 can spray and blast the soil on the left and right sides and the top, resulting in a wider soil loosening coverage.

[0088] A second conical diverter 24 is provided at the end of the deep application rod 3. The tip of the second conical diverter 24 faces the feed inlet of the deep application rod 3. The second conical diverter 24 is matched with the application channel 7 and the discharge hole 8 respectively. To prevent fertilizer from concentrating at the end of the deep application rod 3, the positive pressure material in the deep application rod 3 can be evenly distributed to each discharge hole 8 by setting the second conical diverter 24, ensuring the uniformity of the final fertilization and the fertilization effect.

[0089] The deep loosening rod 2 and deep application rod 3 are equipped with wings 35 on both sides, aligned with the direction of travel of the equipment, and capable of sealing with the soil in contact with the soil. The blasting hole 4 and the discharge hole 8 both penetrate the wings 35. The wings 35 allow for a longer blasting and fertilization distance, and a wider range for deep loosening and spraying. Without the wings 35, the compressed air shock wave would directly blast at the side wall of the wings connected to the deep loosening rod 2. With the wings 35, the compressed air shock wave travels a distance across the width of the wings before blasting, resulting in a longer blasting distance, a wider range, and a greater depth of deep loosening and fertilization. Fertilization follows the same principle. The deep loosening rod 2 is equipped with soil-breaking blades 25, with the cutting edges of the blades 25 positioned in the forward direction of the frame 1. The soil-breaking blades 25 reduce the resistance to the forward movement of the deep loosening rod 2, making its movement smoother.

[0090] As attached Figure 4-5 As shown,

[0091] The traveling wheels include front wheels 30 and rear wheels 31, with two front wheels 30 and two rear wheels 31. The two front wheels 30 and rear wheels 31 are symmetrically arranged along the center line of the frame 1. The traveling compaction wheel 34 is also included. The width of the traveling compaction wheel 34 matches the range of the upward blasting. The traveling compaction wheel 34 is located above the blasting hole 4.

[0092] The device uses wheels to facilitate the movement of the frame 1, and the compaction wheel 34 and the blast hole 4 are located on the same vertical line to prevent the upward blasting airflow from breaking up the soil, thus playing a compaction role and making the upward blasting range wider and larger.

[0093] The frame 1 is also hinged to a flat floor 32, which matches the ground surface. The flat floor 32 is provided with two limiting blocks 33, and the distance between the two limiting blocks 33 gradually decreases from top to bottom. The hinge is preferably a spring hinge.

[0094] It also includes a drive mechanism 36. In this embodiment, the drive mechanism 36 is a tractor. The tractor is detachably connected to the frame 1. The tractor is provided with a hook 19, and the walking frame 1 is provided with a hook ring 20 that matches the hook 19, which facilitates the installation and removal of the drive mechanism 36 and the frame 1. The hook 19 is provided with a pin hole, and a pin is provided in the pin hole to prevent the hook ring 20 from falling off.

[0095] The flat floor 32 is detachably hinged to the frame 1. When the equipment needs to be transported before or after operation, the flat floor 32 can be removed.

[0096] The tractor has two hydraulic cylinders 17 at its upper rear end, and the piston rods of both hydraulic cylinders 17 are hinged to the frame 1. After the work is completed, the pin is first removed, so that the hook 20 is disengaged from the hook 19. Then, the piston rod of the hydraulic cylinder 17 is extended, thereby lifting the frame 1 upward, so that the front wheel 30 is off the ground, and the spraying deep loosening rod 2 and deep application rod 3 are pulled out of the soil. Then, the rear wheel 31 touches the ground to bear the weight, thereby moving the frame 1 away from the soil. When work is needed, a trench is dug in the soil, then the piston rod of the hydraulic cylinder 17 is shortened, and then the spraying deep application rod 3 and deep loosening rod are placed in the trench. The hook 20 is placed on the hook 19, and then the pin is inserted into the pin hole, and then the spraying deep loosening and deep application work begins.

[0097] It also includes a control system, which is electrically connected to the drive mechanism 36, hydraulic cylinder 17, air compressor 12, pressure transmitter 27, inflation solenoid valve 28, explosion solenoid valve 29, hydraulic pump 16, electric valve, and high-frequency vibrator 9. The control system controls the movement and stopping of the drive mechanism 36, controls the air compressor 12 to compress air, opens and closes the inflation solenoid valve 28 and explosion solenoid valve 29, and controls the pressure transmitter 27 to regulate pressure. The control system controls the hydraulic pump 16 to work for feeding and discharging, controls the piston rod of the hydraulic cylinder 17 to extend and retract, thereby lifting and lowering the frame 1, and controls the high-frequency vibrator 9 to turn on and off.

[0098] As attached Figure 5 As shown,

[0099] A method for deep loosening and deep application of seeds using a spray-blasting technique is also disclosed, employing the aforementioned device and comprising the following steps:

[0100] Step S1: Prepare fertilizer by mixing the prepared liquid material, solid-liquid mixture, or powder material according to the soil test formula.

[0101] Step S2: Set parameters, such as the penetration depth, blasting pressure, and feeding speed, according to the soil conditions to be operated.

[0102] Step S3: Operation preparation, put the liquid fertilizer into the feeding box 15, fill the seed box 10 with seeds, connect the drive mechanism 36 to the frame 1, and set the speed of the drive mechanism 36.

[0103] Step S4: Loosening the soil and applying fertilizer. The control system controls the equipment to move while simultaneously spraying and loosening the soil, spraying and applying fertilizer, and sowing seeds.

[0104] The specific operation of step S4 is as follows:

[0105] First, place the frame 1 on the original soil area using the wheels. Then, place the spraying deep loosening rod 2, deep application rod 3, and seeding rod 11 in the original soil area within 60cm. The feeding box 15 holds liquid materials, solid-liquid mixtures, or powder materials. Then, the drive mechanism 36 pulls the frame 1 forward.

[0106] In the deep loosening and deep application zone, the triangular protruding wing connected to the spray-blast deep loosening rod 2 forms a seal between the spray-blast hole and the soil during forward movement. As the self-driven or externally driven mechanism 36 pulls the frame 1 forward, the high-frequency vibrator 9 continuously generates high-frequency vibrations that act on the spray-blast deep loosening rod 2. This high-frequency vibration of the spray-blast deep loosening rod 2 causes soil liquefaction at the soil-breaking blades, resulting in less resistance and faster movement of the spray-blast deep loosening rod 2 in the soil. Simultaneously, during the high-frequency vibration, the spray-blast system performs spray-blasting, generating compressed air that forms a spray-blast in the soil through the spray-blast deep loosening rod 2, loosening the soil. The feeding system sprays liquid fertilizer through the deep application rod 3 under positive pressure, evenly spraying the liquid fertilizer into the gaps between the loosened soil that has not yet returned to its original position. Furthermore, the spray-blasting and deep application under high-frequency vibration reduces forward resistance and improves work efficiency.

[0107] The flat floor 32 in the subsidence area backfills, compacts, and levels the trenches formed by the deep loosening rods 2 and deep application rods 3 during the spraying and fertilization process. Two limiting blocks 33 are used to re-fill the soil pushed aside by the soil-breaking blades 25 back into the trenches and compact it, while also preventing fertilizer from evaporating into the air and causing waste.

[0108] Then, the seeds in the seed box 10 within the collapsed area enter the sowing channel of the sowing rod 11, and then fall from the sowing channel into the backfilled and compacted soil above the trench. The trench is formed by the trajectory of the deep application rod 3, and there is no fertilizer accumulation in the trench; instead, fertilizer is sprayed around the trench. After the seeds in the trench take root, they can move to areas with fertilizer, achieving a combined function of moving, spraying, deep loosening, deep application, and sowing simultaneously. Alternatively, no-till seeding devices or transplanting devices can be used to directly sow or plant seeds and seedlings on loose, fertilized soil. Example 2

[0109] The difference between this embodiment and Embodiment 1 is that multiple sets of spray-on deep loosening rods 2, deep application rods 3, and seeding rods 11 are provided, with corresponding walking compaction wheels 34. The upper ends of the multiple sets of spray-on deep loosening rods 2 and deep application rods 3 are connected to the outlet of the spray-on tank 14 and the discharge port of the hydraulic pump 16 via hoses, respectively. Multiple seeding rods 11 are connected to the seed box. By setting multiple sets of spray-on deep loosening rods 2, deep application rods 3, and seeding rods 11, the range of spray-on deep loosening, deep application, and sowing is increased, and work efficiency is improved. Example 3

[0110] The difference between this embodiment and embodiment 1 is that the seed box 10 and the sowing rod 11 are removed, and the crop transplanting unit is installed on the frame 1 and located at the rear end of the spraying deep loosening rod 2 and the deep application rod 3. The crop seedlings are transplanted in the collapsed area through the crop transplanting unit, realizing the integrated operation of loosening soil, applying fertilizer and transplanting, which improves work efficiency. Example 4

[0111] As attached Figure 6 As shown, this embodiment differs from Embodiment 1 in that the frame 1 is provided with through holes that match the explosive slack rod 2 and the deep application rod 3. The explosive slack rod 2 and the deep application rod 3 are provided with multiple first grooves 37 from top to bottom. The multiple first grooves 37 are symmetrical on both sides of the center line of the explosive slack rod 2 and the deep application rod 3. The frame 1 is provided with a second groove. The second groove is connected to a fixing block 38 that matches the first groove 37 by a spring 39. The end of the fixing block 38 is spherical. The upper end of the first groove 37 is shaped like a spherical groove that matches the end of the fixing block 38. The lower end of the first groove 37 is arc-shaped. The width of the second groove is greater than the width of the fixing block 38, which facilitates the forward and backward movement of the explosive slack rod 2 and the deep application rod 3.

[0112] When the soil conditions for the operation are different, the insertion depth of the blasting deep loosening rod 2 and the deep application rod 3 can be adjusted according to the soil conditions. The blasting deep loosening rod 2 and the deep application rod 3 can be moved up or down in the through hole. After the fixing block 38 is squeezed, it enters the second groove. When the appropriate height is adjusted, the fixing block 38 enters the first groove, thereby fixing the blasting deep loosening rod 2 and the deep application rod 3 on the frame. At the same time, because the fixing block 38 can slide in the second groove, when the high-frequency vibrator 9 vibrates the blasting deep loosening rod 2 and the deep application rod 3 at high frequency, the blasting deep loosening rod 2 and the deep application rod 3 can move back and forth in the through hole. Example 5

[0113] The difference between this embodiment and embodiment 1 is that a spraying system, a feeding system, a deep application rod, and a seeding device constitute a working unit. The number of working units can be increased or decreased according to the soil conditions to reduce operating costs and improve work efficiency.
