Description

Technical Field

[0001] This invention belongs to the field of soil improvement and remediation technology, and specifically relates to an integrated engineering equipment and method for deep loosening and deep application using a spraying and detonation method. Background Technology

[0002] Loosening the soil and applying fertilizer is an important operation in agricultural production. The main function of loosening the soil is to increase the permeability of the topsoil, enhance the exchange capacity of water, fertilizer, heat, and air, and accelerate the formation of soil aggregates. This enhances root respiration and promotes the absorption of mineral elements by the roots.

[0003] In most cases, soil is insufficient to meet the demands of high agricultural yields. Typically, 60-70% of crop yield fertility is provided by basic soil fertility, while the remaining 30-40% comes from fertilization. Therefore, fertilization is an extremely important factor for high yields. Traditionally, loosening the soil and fertilizing were two separate operations; however, with the development of modern agricultural machinery, these two processes have gradually been combined. This combination applies to industrially produced chemical fertilizers; however, conventional organic fertilizers still require specialized machinery or manual application.

[0004] Patent CN105432168A discloses a pneumatic deep tillage and fertilization machine, including a frame, a deep tillage device, an air pump, a fertilization device, and a depth control device. The deep tillage device is located on both sides of the frame and fixed on the shovel handle frame. The fertilization device and the air pump are located on the upper side of the frame, with the fertilization device located behind the air pump. The depth control device is located on both sides of the frame and on the outer side of the side beam.

[0005] This design adds ventilation holes to the handle of the deep tillage shovel, connecting to small holes in the shovel tip. Air is injected via an air compressor in an air pump, covering the shovel tip and flowing into the plow pan to loosen the soil. This helps the shovel tip break up compacted soil, reduces drag, mitigates damage to the shovel tip, increases soil porosity, and promotes fertilizer absorption. However, this design relies solely on pneumatic loosening. When fertilizer is applied directly to the soil along the deep tillage shovel after loosening, it is difficult to distribute the fertilizer evenly around the plant roots, hindering root growth. Furthermore, fertilizer accumulation in the furrows can easily cause seedling burn. Summary of the Invention

[0006] This invention provides an integrated engineering equipment and operation method for deep loosening and application of fertilizer by spraying and detonating, which can solve the problem of not being able to evenly spread fertilizer into the soil after loosening.

[0007] To achieve the above objectives, this solution provides an integrated engineering equipment for deep loosening and deep application using a spray-blasting method, comprising a chassis, a spray-blasting system, a spray-blasting deep loosening rod, and a material feeding system. The chassis is equipped with wheels. Its distinguishing feature is that...

[0008] The detonation deep loosening rod has a detonation channel inside, and at least one detonation hole at its lower end. The detonation hole does not face downwards. The upper end of the detonation channel is connected to the air outlet of the detonation system via a pipe, and the lower end of the detonation channel is connected to the detonation hole. The upper end of the detonation deep loosening rod and the detonation system are connected to the vehicle frame. The detonation system is used to generate compressed air and form a detonation through the detonation deep loosening rod. The detonation deep loosening rod is curved.

[0009] The feeding system includes a feeding box, a discharge pipe, and a three-way valve. The upper end of the discharge pipe is connected to the outlet of the feeding box. The three-way valve has three channels, including a first channel, a second channel, and a third channel. The first channel is connected to the air outlet of the explosion system, the second channel is connected to the discharge pipe, and the third channel is connected to the lower end of the explosion channel. The three-way valve has a rotating tongue inside, which is rotatably connected to the three-way valve. The rotating tongue is located between the first channel and the second channel. The feeding box contains powdered material.

[0010] The spraying deep loosening rod has triangular protruding wings on both sides, and the spraying hole penetrates through the wing. The outer wheel of the triangular protruding wing is aligned with the direction of the equipment's movement and keeps the spraying hole sealed to the soil at all times.

[0011] The principle of this solution is as follows: First, the vehicle frame is placed on the soil via its wheels. Then, the spray-explosion deep loosening rod is placed in the soil to a depth of no more than 60cm. The feed box contains powder and granular materials. The vehicle frame is then moved forward by its own power or drive mechanism. During the forward movement, the spray-explosion deep loosening rod and its connected triangular protruding wings form a seal between the spray holes and the soil. First, the rotating tongue blocks the first channel, and the second channel opens. Then, the powder and granular materials enter the bend of the spray-explosion deep loosening rod and are temporarily stored in the spray-explosion channel. Then, the rotating tongue blocks the second channel, and the first channel opens. At this time, the spray-explosion system generates a compressed air shock wave that enters the spray-explosion deep loosening rod. The powder and granular materials that are temporarily stored in the spray-explosion deep loosening rod are mixed with the compressed air. Then, the spray-explosion deep loosening rod forms a spray-explosion in the soil containing powder and granular materials, loosening the soil, breaking up the compacted clumps, reducing the damage to the spray-explosion deep loosening rod, and increasing the soil porosity. At the same time, the powder or granular materials are evenly sprayed into the soil along with the air, realizing the function of spray-explosion deep loosening and spray-mixing deep application while moving.

[0012] The curved design of the detonation deep loosening rod in this solution allows the powder material to accumulate at the bend in the detonation channel rather than at the end of the detonation deep loosening rod. If the detonation deep loosening rod is set in a vertical shape, the powder material will accumulate at the bottom of the detonation channel, and the subsequently entering compressed air will directly impact the bottom, blocking the powder material at the end of the detonation deep loosening rod and preventing the material from being detonated.

[0013] The beneficial effects of this plan are:

[0014] 1. This solution combines soil loosening and fertilization simultaneously. Fertilizer is sprayed into the loosened soil using a spraying method, and the positive pressure spray ensures a larger and more even fertilization area. Fertilizer does not concentrate in the furrows, preventing seedling burn or inhibited seed germination. Furthermore, the fertilizer is not released into the air, avoiding fertilizer loss and air pollution. It will not be washed away by surface runoff or wind in heavy rain or strong winds, preventing soil erosion. After absorbing the fertilizer, the plant roots penetrate deep into the soil, preventing root systems from rising to the surface. This enhances the crop's ability to absorb nutrients and its resistance to adverse environmental conditions, protecting it from pests, diseases, and other natural disasters. It also encourages roots to extend deeper into the soil, increasing their distribution range and fully utilizing deep soil nutrients and water, while simultaneously improving plant resilience and thus increasing the input-output ratio.

[0015] 2. This method involves simultaneous spraying and fertilization while walking, improving both soil loosening and fertilization efficiency. The working depth is within 60cm, making it applicable to crops with root systems within 60cm, including field crops such as wheat, corn, cotton, and sugarcane, as well as orchards, medicinal herbs, tea gardens, pastures, farmland degraded soil remediation, grasslands, and deserts. The method avoids disturbing the surface soil, which is significant for windy and arid northern regions, reducing dust sources and soil erosion.

[0016] 3. This deep loosening and application method eliminates the need to turn the soil surface, reducing the surface area for evaporation and thus lowering evaporation rates, which is beneficial for soil moisture and nutrient retention. Through spraying and deep loosening, the soil is thoroughly loosened across all areas where crop roots are distributed. The spraying also breaks up soil capillaries, reducing capillary evaporation, which helps retain moisture and prevents soil salinization. It has low energy consumption because the spraying occurs in the lower soil layer, with no strong mechanical resistance, requiring significantly less power compared to traditional moldboard plows and rotary tillers. It has a wide range of applications, suitable for fields, orchards, grasslands, deserts, agricultural non-point source pollution control, and degraded farmland restoration. It can also be used to return biogas slurry and other organic waste to the field as fertilizer.

[0017] 4. This equipment and operating method significantly improve agricultural production efficiency, comprehensively enhance soil aeration, soil aggregate structure, soil ecology, and chemical state, and the effect is rapid, covering all areas of crop growth, and comprehensively improving the soil environment provided by the current crop to achieve high yield.

[0018] Furthermore, the lower end of the explosive slack rod is in the same direction as the equipment's forward movement. The height of the material accumulation at the bend in the explosive channel each time it enters is one-third of the diameter of the explosive channel. The system also includes a control system that controls the direction of the three-way valve's rotary tongue.

[0019] Beneficial effects: The lower end of the spraying deep loosening rod moves in the same direction as the equipment, facilitating its forward movement. The control system controls the direction of the rotating tongue in the three-way branch valve, enabling intelligent operation and reducing manual workload. The bending design of the spraying deep loosening rod ensures that the height of the material accumulated at the bend in the spraying channel is one-third of the diameter of the spraying channel, preventing blockage and facilitating deep loosening and application.

[0020] Furthermore, the explosive slack rod and the discharge pipe are both slidably connected to the frame at the front and rear. The frame is equipped with a high-frequency vibrator that reciprocates linearly along the direction of travel of the equipment. The high-frequency vibrator is used to generate high-frequency vibrations that act on the explosive slack rod.

[0021] Beneficial effects: During the process of manually or by a drive mechanism pulling the frame forward, the high-frequency vibrator continuously generates high-frequency vibrations that act on the blasting and loosening rods. This high-frequency vibration of the blasting and loosening rods liquefies the soil near the soil-breaking blades, reducing the resistance encountered by the blasting and loosening rods as they move through the soil and increasing their speed. Simultaneously, during the high-frequency vibration, the blasting and loosening system performs blasting, generating compressed air shock waves that spread through the blasting and loosening rods in the soil, loosening the soil. Then, under the condition of high-frequency vibration, deep loosening and fertilization are carried out, reducing the resistance to movement and improving work efficiency.

[0022] Furthermore, the discharge pipe is equipped with an electric valve or a reversing valve, and the material box is mounted on the vehicle frame.

[0023] Beneficial effects: When spraying, loosening soil, fertilizing, and sowing are required, the electric valve is opened; during non-operational times, the electric valve is closed.

[0024] Furthermore, the high-frequency vibrator is fixedly connected to the blow-off deep loosening rod.

[0025] Beneficial effects, facilitating the direct application of high-frequency vibrators to the blow-down deep loosening rod.

[0026] Furthermore, the explosion system 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.

[0027] 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 soil compaction, and loosen a wider area with faster operation.

[0028] Furthermore, the upper end of the blasting deep loosening rod is inclined, and the length of the upper end of the blasting deep loosening rod is greater than 60cm.

[0029] Beneficial effects: Facilitates deep loosening and deep application of soil within a depth of 60cm.

[0030] Furthermore, the lower end of the spray-blown deep loosening rod is detachably connected to a spray-blown deep loosening head.

[0031] Beneficial effects include reducing the processing difficulty of deep loosening rods and saving costs.

[0032] Furthermore, it also includes a replenishment system, which is used to replenish materials in the gaps after the blowdown deep loosening rod and the wing have traveled.

[0033] Beneficial effects: The feeding system ensures that the soil being deep-tumbled is sprayed with the material.

[0034] Furthermore, the outer periphery of the deep tapping head is cone-shaped, and the deep tapping head extends outward to form radial triangular protrusions.

[0035] Beneficial effect: The radial triangular protrusions can reduce airflow resistance and facilitate the forward movement of the deep pine pole.

[0036] Furthermore, a conical diverter is provided inside the end of the detonation deep loosening head, with the cone tip of the conical diverter facing the air inlet of the detonation deep loosening rod. The conical diverter is matched with the detonation channel and the detonation hole respectively. An outer ring body is provided at the outer end of the detonation deep loosening rod, and an internal thread is provided on the outer ring body. The end of the detonation deep loosening head is provided with an external thread back clamp that matches the internal thread. Multiple detonation holes are provided, and the multiple detonation holes are distributed along the left and right sides and the upper side of the lower end of the detonation deep loosening rod.

[0037] 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 and the deep loosening rod are spirally connected, 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.

[0038] 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.

[0039] Beneficial effects: The soil-breaking blades can reduce the resistance of the deep loosening rod, making its movement smoother.

[0040] 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.

[0041] 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 inflation solenoid valve prevents the compressed air from flowing back. The detonation solenoid valve is a key component of the detonation system and is used to open and close the detonation tank.

[0042] 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, and the center line of the traveling compaction wheel is located above the center line of the blasting hole.

[0043] 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 range wider.

[0044] 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.

[0045] Beneficial effects: Facilitates the installation and disassembly of the drive mechanism and frame.

[0046] Furthermore, the vehicle frame is also hinged with a flat floor that matches the ground surface. The flat floor has two limiting blocks, and the distance between the two limiting blocks gradually decreases from top to bottom. The hinge is preferably a spring hinge.

[0047] Beneficial effects: The flat floor is used to backfill, level and compact the trenches formed by the deep loosening rods during the spraying and blasting fertilization process, preventing the material from volatilizing into the air, causing waste and air pollution. The two limiting blocks are used to re-fill the soil pushed away by the soil-breaking blades into the trenches.

[0048] Furthermore, the feeding system includes a material box, a hydraulic pump, and a conveying pipe. The upper end of the conveying pipe and the material box are both mounted on the frame. The two ends of the hydraulic pump are respectively connected to the upper end of the conveying pipe and the discharge port of the material box. The length of the conveying pipe matches the length of the deep-applying rod. The left and right sides and the rear end of the conveying pipe are provided with second discharge holes. The second discharge holes on the left and right sides of the conveying pipe correspond to the positions of the wings. The material box is used to hold liquid materials.

[0049] Beneficial effects: When the width of the wing on the deep loosening rod is greater than 10cm, the area where the wing passes cannot be sprayed with material, and the trenches formed at the rear end of the deep loosening rod cannot be sprayed with material either. Therefore, by setting up a material box and a conveying pipe, material can be sprayed on the area where the wing passes and the trenches, making the area where the soil is sprayed with material wider. The material is conveyed to the conveying pipe under positive pressure by a hydraulic pump, and then the material is sprayed from the second discharge hole in the conveying pipe into the gaps left by the wing. Because the equipment moves continuously, when the wing on the deep loosening rod leaves gaps in the soil but the gaps are not yet covered by the loosened soil, the material is sprayed from the second discharge hole, thus making the area where the wing passes also sprayed with material, resulting in a wider and more comprehensive spraying range.

[0050] Furthermore, a method for operating an integrated engineering equipment for deep loosening and deep application using a spray-blasting method is also disclosed, which employs the aforementioned device and includes the following steps:

[0051] Step S1: Prepare materials by placing the powdered material into the feeding hopper.

[0052] Step S2: Set parameters, such as the penetration depth, blasting pressure, and feeding speed, according to the soil conditions to be operated.

[0053] Step S3: Operation preparation, connect the drive mechanism to the frame, and set the speed of the drive mechanism.

[0054] Step S4: Loosen the soil and apply fertilizer. While walking, spray the soil to loosen it and apply fertilizer. Attached Figure Description

[0068] Example 1 is attached. Figure 1 As shown, an integrated engineering equipment for deep loosening and deep application using a spray-blasting method includes a frame 1, a spray-blasting system, a spray-blasting deep loosening rod 2, and a material supply system. The frame 1 is equipped with wheels, and the spray-blasting deep loosening rod 2 is equipped with a spray-blasting channel 3. In this embodiment, the lower end of the spray-blasting deep loosening rod 2 is provided with three spray-blasting holes 4, which are distributed on the left and right sides and the upper end of the cross-section of the spray-blasting deep loosening rod 2, respectively.

[0069] The upper end of the explosion channel 3 is connected to the air outlet of the explosion system via a pipe, and the lower end of the explosion channel 3 is connected to the explosion hole 4. The upper end of the explosion slack rod 2 and the explosion system are connected to the frame 1. The explosion system is used to generate compressed air and form an explosion through the explosion slack rod 2.

[0070] As attached Figure 2-3As shown, the feeding system includes a feeding box 5 and a discharge pipe 6. The upper end of the discharge pipe 6 is connected to the outlet of the feeding box 5, and the lower end of the discharge pipe 6 is connected to the spray-blasting deep loosening rod 2. An electric valve is installed on the discharge pipe 6, and the feeding box is mounted on the vehicle frame. When spray-blasting loosening and fertilization operations are required, the electric valve is opened; during non-operational times, the electric valve is closed.

[0071] The deep loosening rod 2 has wings 28 on both sides, with spray holes 4 penetrating through the wings 28. By setting the wings, the spray holes on the triangular protrusion wings can form a better seal with the soil. The wings 28 also allow for a longer spraying and fertilization distance. Without the wings 28, the compressed air would spray directly onto the side wall of the deep loosening rod 2. With the wings 28, the compressed air travels a distance across the width of the wings before spraying, resulting in a longer spraying distance, a wider deep loosening range, and a deeper penetration.

[0072] The explosive slack rod 2 is curved, with its lower end set horizontally to facilitate forward movement. Both the explosive slack rod 2 and the discharge pipe 6 are slidably connected to the frame 1. The frame 1 is provided with a sliding groove, and both the explosive slack rod 2 and the discharge pipe 6 are provided with sliders that match the sliding groove.

[0073] The frame 1 is equipped with a high-frequency vibrator 7 that reciprocates linearly in the same direction as the equipment's travel. The high-frequency vibrator 7 is used to generate high-frequency vibrations that act on the detonation deep loosening rod 2. The high-frequency vibrator 7 is fixedly connected to the detonation deep loosening rod 2, so that the high-frequency vibrator 7 can directly act on the detonation deep loosening rod 2.

[0074] During the process of manually or through the drive mechanism 22 pulling the frame 1 forward, the high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the blasting and loosening rod 2. This causes the blasting and loosening rod 2 to vibrate the soil, liquefying the soil around the soil-breaking blades. This reduces the resistance encountered by the blasting and loosening rod 2 as it moves forward through the soil, allowing it to move faster. Simultaneously, during the high-frequency vibration, the blasting system performs blasting, generating compressed air that is then blasted through the blasting and loosening rod 2 to loosen the soil. Then, under the condition of high-frequency vibration, deep loosening and fertilization are carried out, reducing the resistance to movement and improving work efficiency.

[0075] As attached Figure 4As shown, the feeding system includes a feeding box 5, a discharge pipe 6, and a three-way diverter valve 36. The upper end of the discharge pipe 6 is connected to the outlet of the feeding box 5. The three-way diverter valve 36 has three channels, including a first channel 37, a second channel 38, and a third channel 39. The first channel 37 is connected to the air outlet of the explosion system, the second channel 38 is connected to the discharge pipe 6, and the third channel 39 is connected to the lower end of the explosion channel 3. The three-way diverter valve 36 has a rotating tongue 40 inside, which is rotatably connected to the three-way diverter valve 36 and is located between the first channel 37 and the second channel 38. The feeding box 5 contains powdered materials. The system also includes a control system, which controls the direction of the rotating tongue 40 of the three-way diverter valve.

[0076] The explosion system includes an air compressor 9, an energy storage tank 10, and an explosion canister 11. The energy storage tank 10 is connected to the air compressor 9 and the explosion canister 11 through pipes. The outlet of the explosion canister 11 is connected to the upper end of the explosion channel 3 through a hose. The first channel 37 is connected to the air outlet of the explosion canister 11.

[0077] The storage tank 10 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 11 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 soil compaction, and loosen the soil over a wider area.

[0078] 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.

[0079] 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 range of spraying and deep loosening and the range of material deep application to be expanded in a controllable manner.

[0080] 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.

[0081] An oil-water separator 8 is connected to the pipeline between the air compressor 9 and the energy storage tank 10. The oil-water separator 8 is used to separate the water in the air compressor 9. In this embodiment, the air compressor 9 is an air compressor.

[0082] A pressure transmitter 17 and a gas filling solenoid valve 18 are installed on the pipeline between the energy storage tank 10 and the explosion tank 11. The explosion tank 11 is electrically connected to the explosion solenoid valve 19, and the pressure transmitter 17 is located between the explosion solenoid valve 19 and the explosion tank 11.

[0083] The compressed air from the air compressor 9 enters the energy storage tank 10. The pressure of the compressed air in the energy storage tank 10 is regulated by the pressure transmitter 17 to provide the appropriate detonation pressure to the detonation canister 11. The inflation solenoid valve 18 prevents the compressed air from flowing back. The detonation solenoid valve 19 is the main component for detonation and is used to open and close the detonation canister 11.

[0084] The upper end of the spray-drying deep loosening rod 2 is inclined, and its length is greater than 60cm. This facilitates deep loosening and application of soil with a depth of up to 60cm. The lower end of the spray-drying deep loosening rod 2 is detachably connected to a spray-drying head 12. This reduces the processing difficulty of the spray-drying deep loosening rod 2 and saves costs.

[0085] The outer periphery of the deep-plowing nozzle 12 is cone-shaped, and the nozzle extends outward to form radial triangular protrusions 13. The radial triangular protrusions 13 can reduce airflow resistance. The diameter of the deep-plowing nozzle 12 at its maximum point is less than or equal to the diameter of the deep-plowing rod 2.

[0086] The end of the deep loosening head 12 is provided with a conical diverter 14. The cone tip of the conical diverter 14 faces the air inlet of the deep loosening rod 2. The conical diverter 14 is matched with the detonation channel 3 and the detonation hole 4 respectively. The outer end of the deep loosening rod 2 is provided with an outer ring body 15. The outer ring body 15 is provided with an internal thread. The end of the deep loosening head 12 is provided with an external thread or a clasp that matches the internal thread. There are multiple detonation holes 4. The multiple detonation holes 4 are distributed along the left and right sides and the top end of the cross-section of the deep loosening rod 2.

[0087] Because the high-pressure gas injected into the deep loosening rod 2 has high pressure and high velocity, it is easy for the high-pressure airflow to all 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 14 of the above-mentioned structure, the high-pressure air in the deep loosening rod 2 can be evenly distributed to each injection hole, ensuring the uniformity of the final soil loosening and the soil loosening effect. The deep loosening head 12 is spirally connected to the deep loosening rod 2, which is convenient for disassembly and installation, and the multiple explosion holes 4 can explode the soil on the left and right sides and the top, resulting in a wider soil loosening coverage.

[0088] The blasting deep loosening pole 2 is equipped with a soil-breaking blade 16, the cutting edge of which is located in the forward direction of the frame 1. The soil-breaking blade 16 can reduce the resistance to the forward movement of the blasting deep loosening pole 2, making the blasting deep loosening pole 2 move more smoothly.

[0089] As attached Figure 5-6As shown,

[0090] The traveling wheels include front wheels 20 and rear wheels 21, with two front wheels 20 and two rear wheels 21. The two front wheels 20 and rear wheels 21 are symmetrically arranged along the center line of the frame 1. The traveling compaction wheel 29 is also included. The width of the traveling compaction wheel 29 matches the range of upward blasting, and the center line of the traveling compaction wheel 29 is located above the center line of the blasting hole 4.

[0091] The device uses wheels to facilitate the movement of the frame 1, and the centerline of the compaction wheel 29 is on the same plane as the centerline of the blast hole 4. This prevents the upward blasting airflow from breaking up the soil, thus compacting it and allowing for a wider range of upward blasting.

[0092] It also includes a drive mechanism 22. In this embodiment, the drive mechanism 22 is a tractor. The tractor is detachably connected to the frame 1. The tractor is provided with a hook 26, and the walking frame 1 is provided with a hook ring 27 that matches the hook 26, which facilitates the installation and removal of the drive mechanism 22 and the frame 1. The hook 26 is provided with a pin hole, and a pin is provided in the pin hole to prevent the hook ring 27 from falling off.

[0093] The tractor has two hydraulic cylinders 25 at its upper rear end, and the piston rods of both hydraulic cylinders 25 are hinged to the frame 1. After the work is completed, the pin is first removed, so that the hook 27 is disengaged from the hook 26. Then, the piston rod of the hydraulic cylinder 25 is extended, thereby lifting the frame 1 upward, so that the front wheel 20 is off the ground, and the deep loosening rod 2 and the deep application rod are pulled out of the soil. Then, the rear wheel 21 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 25 is shortened, and then the deep loosening rod 2 and the deep application rod are placed in the trench. The hook 27 is placed on the hook 26, and then the pin is inserted into the pin hole, and then the deep loosening and deep application work begins.

[0094] The flat floor 23 is detachably hinged to the frame 1. It can be removed before or after operation when the equipment needs to be transported. The flat floor 23 conforms to the ground surface and has two limiting blocks 24, the distance between which gradually decreases from top to bottom. The flat floor 23 is used to backfill, compact, and level the trenches formed by the deep loosening rods 2 during the spraying and fertilization process, preventing fertilizer from evaporating into the air, causing waste and environmental pollution. The two limiting blocks 24 are used to re-fill the soil pushed aside by the soil-breaking blades 16 back into the trenches.

[0095] The control system is electrically connected to the drive mechanism 22, hydraulic cylinder 25, air compressor 9, pressure transmitter 17, inflation solenoid valve 18, detonation solenoid valve 19, electric valve, and high-frequency vibrator 7. The control system controls the movement and stopping of the drive mechanism 22, controls the air compressor 9 to compress air, opens and closes the inflation solenoid valve 18 and detonation solenoid valve 19, and controls the pressure transmitter 17 to regulate pressure. The control system controls the extension and retraction of the piston rod of the hydraulic cylinder 25 to lift and lower the frame 1, and controls the opening and closing of the high-frequency vibrator 7. The soil areas that have not undergone detonation, deep loosening, and deep application are called the original soil areas. The purpose of the original soil areas is to seal the detonation holes at the leading edge of the triangular-shaped wing, facilitating subsequent detonation.

[0096] 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 range of spraying and deep loosening and the range of material deep application to be expanded in a controllable manner.

[0097] 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.

[0098] A method for operating an integrated engineering equipment for deep loosening and deep application using a spray-blasting method, employing the aforementioned device, includes the following steps:

[0099] Step S1: Prepare the materials by placing the powdered material into the feeding box 5.

[0100] Step S2: Set parameters, such as the penetration depth, blasting pressure, and feeding speed, according to the soil conditions to be operated.

[0101] Step S3: Operation preparation, connect the drive mechanism 22 to the frame 1, and set the speed of the drive mechanism 22;

[0102] Step S4: Loosen the soil and apply fertilizer. While walking, spray the soil to loosen it and apply fertilizer. Example

[0103] As attached Figure 7-8As shown, this embodiment differs from Embodiment 1 in that it also includes a feeding system. The feeding system includes a material box 33, a hydraulic pump 41, and a conveying pipe 34. The upper ends of the hydraulic pump 41, the conveying pipe 34, and the material box 33 are all mounted on the frame 1. The two ends of the hydraulic pump 41 are respectively connected to the upper end of the conveying pipe 34 and the discharge port of the material box 33. The length of the conveying pipe 34 matches the length of the spray-blown deep loosening rod 2. The left and right sides and the rear end of the conveying pipe 34 are provided with second discharge holes 35. The second discharge holes 35 on the left and right sides of the conveying pipe 34 correspond to the positions of the wing 28. The material box 33 is used to hold liquid materials.

[0104] When the width of the wing 18 on the deep loosening rod is greater than 10cm, the area where the wing 28 on the deep loosening rod 2 passes cannot be sprayed with material, and the trench formed at the rear end of the deep loosening rod 2 cannot be sprayed with material either. Therefore, by setting up a material box 33 and a conveying pipe 34, material can be sprayed on the area where the wing 28 passes and the trench, so that the area where the soil is sprayed with material is wider. The material is conveyed to the conveying pipe 34 under positive pressure by the hydraulic pump 41, and then the material is sprayed from the second discharge hole 35 in the conveying pipe 34 into the gap left by the wing 28. Because the equipment continues to move, when the wing on the deep loosening rod 2 leaves a gap in the soil but the gap has not yet been covered by the loosened soil, the material is sprayed from the second discharge hole 35, so that the area where the wing passes is also sprayed with material, and the spraying range is wider and more comprehensive. Example

[0105] As attached Figure 9-10 As shown, this embodiment differs from Embodiment 1 in that it also includes a feeding system. The feeding system includes a material box 33, a conveying pipe 34, a rotating motor 42, and a rotating shaft 44. The material box 33 contains powder or granular materials. Both ends of the conveying pipe 34 are not sealed. The output shaft of the rotating motor 42 is coaxially and fixedly connected to the rotating shaft 44. The upper end of the conveying pipe 34 is rotatably and sealed to the rotating shaft 44. The bottom of the rotating shaft 44 protrudes from the conveying pipe 34. The bottom of the rotating shaft 44 is provided with a spiral blade 45. Part of the spiral blade 45 is located inside the conveying pipe 34, and the other part is located outside the conveying pipe 34. The rotating motor 42 is mounted on the frame. The material box 33 is connected to the conveying pipe 34. A discharge valve 43 is provided at the outlet of the material box 33. The discharge valve 43 and the rotating motor 42 are both electrically connected to the controller. The spiral blade 45 is matched with the wing 28.

[0106] When the width of the wing on the deep-soil loosening rod is greater than 10cm, the area where the wing 28 on the deep-soil loosening rod 3 passes cannot be sprayed with material, and the grooves formed at the rear end of the deep-soil loosening rod 3 when it moves cannot be sprayed with material. When the equipment is in operation, the controller opens the feeding valve 43 and controls the rotation of the rotating motor 42, so that the material enters the conveying pipe 34 from the material box 33. Then the output shaft of the motor rotates, driving the rotating shaft 44 to rotate, which in turn drives the spiral blade 45 to rotate, spraying powdery and granular materials. The material is sprayed into the gaps left by the wing 28 as it moves through the soil. At this time, the gaps are not yet covered by the loosened soil. At the same time, the material is also sprayed into the grooves formed when the deep-soil loosening rod 2 moves. In addition, when the material box 33 contains granular materials, the high-speed rotating spiral blade 45 can also break up and throw the granular materials. Example

[0107] The difference between this implementation and Example 1 is that multiple sets of the spray-blast deep loosening rods 2 and discharge pipes 6 are provided, with corresponding walking compaction wheels 29. The upper ends of the multiple sets of spray-blast deep loosening rods 2 and discharge pipes 6 are connected to the outlet of the spray-blasting tank 11 and the discharge port of the feeding box via flexible hoses. By setting multiple sets of spray-blast deep loosening rods 2 and discharge pipes 6, the range of spray-blast deep loosening and deep application is increased, and work efficiency is improved. Example

[0108] As attached Figure 11 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 discharge pipe 6. The explosive slack rod 2 and the discharge pipe 6 are provided with multiple first grooves 30 from top to bottom. The multiple first grooves 30 are symmetrical on both sides of the center line of the explosive slack rod 2 and the discharge pipe 6. The frame 1 is provided with a second groove. The second groove is connected to a fixing block 31 that matches the first groove 30 by a spring 32. The end of the fixing block 31 is spherical. The upper end of the first groove 30 is shaped like a spherical groove that matches the end of the fixing block 31. The lower end of the first groove 30 is arc-shaped. The width of the second groove is greater than the width of the fixing block 31, which facilitates the forward and backward movement of the explosive slack rod 2 and the discharge pipe 6.

[0109] When the soil conditions for the operation are different, the insertion depth of the blasting deep loosening rod 2 can be adjusted according to the soil conditions. The blasting deep loosening rod 2 and the discharge pipe 6 can be moved up or down in the through hole. After the fixing block 31 is squeezed, it enters the second groove. When the appropriate height is adjusted, the fixing block 31 enters the first groove 30, thereby fixing the blasting deep loosening rod 2 and the discharge pipe 6 on the frame 1. At the same time, because the fixing block 31 can slide in the second groove, when the high-frequency vibrator 7 performs high-frequency vibration on the blasting deep loosening rod 2 and the discharge pipe 6, the blasting deep loosening rod 2 and the discharge pipe 6 can move back and forth in the through hole. Example

[0110] This embodiment discloses a method for deep loosening and application of spray-on soil for grassland restoration and desertification control, comprising the following steps:

[0111] Step 1: Conduct on-site geological surveys and soil sampling of the grassland soil, and then configure materials according to the results of the on-site geological surveys and soil sampling. The materials are as follows:

[0112] Soil remediation agent: The soil remediation solution is obtained by mixing microbial liquid and soil remediation agent in a ratio of 1.5:1. The microbial liquid contains compound bacterial agents, nitrogen-fixing rhizobia, phosphate-solubilizing bacteria, lactic acid bacteria, actinomycetes, etc. The main components of the soil remediation agent are Bacillus subtilis, rhizobium agents, nitrogen-fixing bacteria agents, phosphate-solubilizing microbial agents, silicate microbial agents, photosynthetic bacteria agents, organic material composting agents, growth-promoting agents, mycorrhizal fungi agents, bioremediation agents, etc.

[0113] Soil conditioner: Polymeric amino acids obtained from the hydrolysis of feathers, with amino acid content ≥150g / L and organic matter content ≥1240g / L.

[0114] Water-soluble fertilizer: Nitrogen:Phosphorus:Potassium = 18:18:18:18, total content ≥54%, potassium sulfate fully water-soluble type.

[0115] Biogas slurry (fermentation liquid of livestock and poultry manure): 10 tons.

[0116] Micronutrient fertilizer: Agricultural crop growth regulator fertilizer composed of trace elements such as magnesium, zinc, boron, and iron.

[0117] Step 2: Set parameters. First, measure the porosity of the soil, and then set the penetration depth and blasting pressure according to the soil conditions. The equipment parameters are set as follows: penetration depth 60cm; pressure 0.8-1.2MPa; material flow rate 30L / s.

[0118] Step 3: Operation preparation: Load the material into the feed box 5, connect the tractor to the frame 1, and set the tractor speed;

[0119] Step 4: Loosening the soil and applying materials, spraying materials under positive pressure while walking.

[0120] Step four is as follows: Using integrated deep loosening and application equipment, the vehicle frame 1 is first placed on the grassland soil in the original soil area via its wheels. The deep loosening rod 2 is placed in the soil to a depth of 60cm. A trench is dug in the soil. Then, the piston rod of the hydraulic cylinder 25 is shortened, and the deep loosening rod 2 is placed in the trench. The hook ring 27 is placed on the hook 26, and the pin is inserted into the pin hole. Then, the deep loosening and application operation begins. The drive mechanism 22 pulls the vehicle frame 1 forward, and the built-in deep loosening and application equipment... During its forward movement, the wing 28 of the channel maintains a seal between the blast hole 4 and the original soil area. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the blasting and loosening rod 2, causing the blasting and loosening rod 2 to vibrate against the soil, liquefying the soil near the soil-breaking blade 16. This reduces the resistance encountered by the blasting and loosening rod 2 as it moves through the soil. Then, the controller controls the air compressor 9 to compress air into the energy storage tank 10, and the pressure of the compressed air in the energy storage tank 10 is regulated by the pressure transmitter 17. The controller provides the appropriate detonation pressure to the detonation canister 11, and controls the detonation solenoid valve 19 to open the detonation canister 11. Then, the electric valve on the discharge pipe 6 is opened, and the controller controls the rotary tongue 40 to block the first channel 37 and open the second channel 38. The powdery material then enters the bend of the detonation deep loosening rod 2 and is temporarily stored in the detonation channel 3. Then, the rotary tongue 40 blocks the second channel 38 and opens the first channel 37. At this time, the detonation system generates a compressed air shock wave that enters the detonation deep loosening rod 2, thereby detonating the material that has been temporarily stored in the deep loosening rod 2. The material is mixed with compressed air and then sprayed into the soil through the spraying deep loosening rod 2, loosening the soil, breaking up compacted clumps, and simultaneously spraying the material evenly into the soil along with the air. This allows for simultaneous spraying and deep loosening while moving around, as well as spraying and mixing deep application. The leveling floor 23 backfills, levels, and compacts the trenches formed by the spraying deep loosening rod 2 during the spraying and fertilization process, preventing fertilizer from evaporating into the air, causing waste and atmospheric pollution. Two limiting blocks 24 are used to re-bury the soil pushed away by the soil-breaking blade 16 back into the trenches. This method enables in-situ meteorological spraying deep loosening of compacted soil in 2-5 year old alfalfa planting areas without disturbing the topsoil; it also achieves a protective no-till technology for in-situ deep loosening and directional spraying and mixing deep application of materials in compacted alfalfa areas. Moreover, this solution uses wings 28 to improve the sealing effect between the spray holes on the wings 28 and the soil, and the wings 28 also allow for a longer spraying and fertilization distance.

[0121] Due to the local climate and scarce rainfall, water supply can only be obtained through irrigation from the Yellow River or well water. Once sown, the land cannot be tilled or loosened for 4-6 years until crop rotation, and fertilization is entirely done through surface application. After years of cultivation, this has resulted in extreme soil compaction, severe salinization in some areas, a soaring mortality rate for alfalfa seedlings, and extremely low fertilizer utilization. This equipment enables deep loosening of grasslands and compacted alfalfa fields through spraying and targeted spraying and deep application of materials. This increases the height of alfalfa while reducing plant mortality, ensuring a sufficient seedling population, increasing alfalfa yield per unit area, and improving dry matter accumulation, thereby enhancing the economic benefits of forage cultivation. Example

[0122] This embodiment discloses a method for deep loosening and deep application of spray-and-blast soil for saline-alkali land improvement, including the following steps:

[0123] Step 1: Conduct on-site geological surveys and soil sampling of the original saline-alkali soil. Then, based on the results of the on-site geological surveys and soil sampling, prepare the materials as follows:

[0124] Compound fertilizer: Sinochem produces potassium sulfate type ternary compound fertilizer with N:P:K2O=15:15:15 and a total effective content ≥45%.

[0125] Soil conditioner: Polymeric amino acids obtained from the hydrolysis of feathers, with amino acid content ≥150g / L and organic matter content ≥1240g / L.

[0126] Soil remediation agent: The soil remediation agent is made by mixing Jixiangyu microbial fertilizer and soil remediation agent in a ratio of 1.5:1. The microbial agent contains compound bacterial agents, nitrogen-fixing rhizobia, phosphate-solubilizing bacteria, lactic acid bacteria, actinomycetes, etc. The main components of the soil remediation agent are Bacillus subtilis, rhizobium agents, nitrogen-fixing bacteria agents, phosphate-solubilizing microbial agents, silicate microbial agents, photosynthetic bacteria agents, organic material composting agents, growth-promoting agents, mycorrhizal fungi agents, bioremediation agents, etc.

[0127] Filler: 500 kg of corn flour.

[0128] Homemade bio-fertilizer: using cow and sheep manure as the main raw material, approximately 80 tons.

[0129] Step 2: Dredging the canal system, specifically including the construction of underground drainage pipes, ditches, or tunnels; the depth should be 120cm and the width 100cm, creating favorable topographical conditions for salt washing and drainage; prepare a fresh water source: one electric well, and supporting irrigation equipment including power supply, water pump and pipelines.

[0130] Step 3: Set parameters. Set the penetration depth and blasting pressure according to the soil conditions. The equipment parameters are set as follows: shock wave blasting for deep loosening of soil 50-60cm.

[0131] Step 4: Drip irrigation and rinsing. Use fresh water wells to irrigate and rinse the salt once (water consumption ≥ 150 cubic meters / acre). After 24 hours, drain the salt water that has entered the salt pond through the drainage ditch. Repeat this process twice, and then let it dry for 7-10 days.

[0132] Step 5: Operation preparation, load the material into the feed box 5, connect the tractor to the frame 1, and set the tractor speed;

[0133] Step Six: Loosening the soil and applying materials, spraying materials under positive pressure while walking;

[0134] Step six is ​​as follows: Using integrated deep loosening and application equipment, the vehicle frame is first placed on the soil in the original soil area via its wheels. The deep loosening and application rods are placed in the soil to a depth of 50-60cm. A trench is dug in the soil. Then, the piston rod of the hydraulic cylinder 25 is shortened, and the deep loosening rod 2 is placed in the trench. The hook 27 is placed on the hook 26, and the pin is inserted into the pin hole. The deep loosening and application operation then begins. The drive mechanism 22 pulls the vehicle frame 1 forward, and the built-in sprayer... During its forward movement, the wings 28 of the blasting channel and material channel maintain a seal between the blasting hole 4 and the original soil area. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the blasting deep loosening rod 2, causing the blasting deep loosening rod 2 to vibrate high-frequency vibrations on the soil, liquefying the soil near the soil-breaking blade 16. This reduces the resistance encountered by the blasting deep loosening rod 2 as it moves forward through the soil. Then, the controller controls the air compressor 9 to compress air into the energy storage tank 10, and the pressure transmitter 17 transmits the compressed air pressure in the energy storage tank 10 to the... The system adjusts to provide the appropriate detonation pressure to the detonation canister 11. The controller controls the detonation solenoid valve 19 to open the detonation canister 11, and then the electric valve on the discharge pipe 6 is opened. The controller controls the rotary tongue 40 to block the first channel 37 and open the second channel 38, allowing the powdery material to enter the bend of the detonation deep loosening rod 2 and temporarily accumulate in the detonation channel 3. Then, the rotary tongue 40 blocks the second channel 38 and opens the first channel 37. At this time, the detonation system generates a compressed air shock wave that enters the detonation deep loosening rod 2 and briefly resides in it. The material is mixed with compressed air and then sprayed into the soil through the spraying deep loosening rod 2 to loosen the soil, break up the compacted clumps, and at the same time the material is evenly sprayed into the soil along with the air, realizing the function of spraying deep loosening and spraying and mixing deep application while walking. The flat floor 23 backfills, levels and compacts the trenches formed by the spraying deep loosening rod 2 during the spraying fertilization process to prevent fertilizer from volatilizing into the air, causing waste and air pollution. The two limiting blocks 24 are used to re-bury the soil pushed away by the soil breaking blade 16 back into the trenches.

[0135] By spraying materials into the soil, the salt and alkali in the saline soil layer are quickly dissolved and the water seeps out rapidly from the cracks and fissures, thereby achieving the purpose of rapid and efficient salt washing; and realizing the protective soil remediation no-till technology of secondary in-situ deep loosening of saline soil and directional spraying and deep application of soil amendment materials.

[0136] The intelligent in-situ loosening and application technology for saline-alkali land remediation involves first adding fresh water to the feeding box for deep loosening and air blasting, followed by rapid washing and removal of salt and alkali. Then, materials are added to the feeding box for deep loosening and air blasting, while soil remediation and improvement materials are added to the soil. This comprehensive approach, which combines the application of manure and the planting of salt-tolerant forage grasses, significantly reduces the soil salinity to the point where crops can grow normally and increases the soil organic matter content. It effectively remediates and improves saline-alkali soil with remarkable results. Example

[0137] This embodiment discloses a method for deep loosening and deep application of spray-and-blast soil for improving soil fertility of high-value crops, including the following steps:

[0138] Step 1: Conduct on-site investigation and soil sampling of the original soil. Then, based on the results of the on-site investigation and soil sampling, configure the materials as follows:

[0139] Soil remediation solution: Soil remediation solution is obtained by mixing microbial liquid and soil remediation agent in a ratio of 1.5:1. The microbial liquid contains compound bacterial agents, nitrogen-fixing rhizobia, phosphate-solubilizing bacteria, lactic acid bacteria, actinomycetes, etc. The main components of the soil remediation agent are Bacillus subtilis, rhizobium agents, nitrogen-fixing bacteria agents, phosphate-solubilizing microbial agents, silicate microbial agents, photosynthetic bacteria agents, organic material composting agents, growth-promoting agents, mycorrhizal fungi agents, bioremediation agents, etc.

[0140] Soil conditioner: It is made by mixing polymeric amino acids obtained from the hydrolysis of feathers and water-soluble fertilizer in a 5:4 ratio. The amino acid content is ≥150g / L and the organic matter content is ≥1240g / L. The water-soluble fertilizer is nitrogen:phosphorus:potassium = 18:18:18:18, with a total content of ≥54% and is potassium sulfate fully water-soluble.

[0141] Step 2: Set parameters. First, measure the porosity of the soil, and then set the penetration depth and blasting pressure according to the soil conditions. The equipment parameters are set as follows: penetration depth 60cm; pressure 0.8-1.2MPa; material quantity 30L / batch.

[0142] Step 3: Operation preparation: Load the material into the feed box 5, connect the tractor to the frame 1, and set the tractor speed;

[0143] Step 4: Loosening the soil and applying materials, spraying materials under positive pressure while walking.

[0144] Step four is as follows: Using integrated deep loosening and deep application equipment, the vehicle frame is first placed on the soil in the original soil area via its wheels. The deep loosening and deep application rods are placed in the soil to a depth of 60cm. A trench is dug in the soil. Then, the piston rod of the hydraulic cylinder 25 is shortened, and the deep loosening rod 2 is placed in the trench. The hook 27 is placed on the hook 26, and the pin is inserted into the pin hole. Then, the deep loosening and deep application operation begins. The drive mechanism 22 pulls the vehicle frame 1 forward, and the built-in explosive channel... During its forward movement, the wing 28 of the tunnel and material passage maintains a seal between the blast hole 4 and the original soil area. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the blasting and loosening rod 2, causing the blasting and loosening rod 2 to vibrate high-frequency vibrations on the soil, liquefying the soil near the soil-breaking blade 16. This reduces the resistance encountered by the blasting and loosening rod 2 as it moves forward through the soil. Then, the controller controls the air compressor 9 to compress air into the energy storage tank 10, and the pressure transmitter 17 transmits the compressed air pressure in the energy storage tank 10 to the... The system adjusts the pressure to provide the appropriate detonation pressure to the detonation canister 11. The controller controls the detonation solenoid valve 19 to open the detonation canister 11, and then the electric valve on the discharge pipe 6 is opened. The controller controls the rotary tongue 40 to block the first channel 37 and open the second channel 38, allowing the material to enter the bend of the detonation deep loosening rod 2 and temporarily accumulate in the detonation channel 3. Then, the rotary tongue 40 blocks the second channel 38 and opens the first channel 37. At this time, the detonation system generates a compressed air shock wave that enters the detonation deep loosening rod 2, thus detonating the material that has been temporarily stored in the deep loosening rod 2. The material is mixed with compressed air and then sprayed into the soil through the spray-explosion deep loosening rod 2, loosening the soil, breaking up compacted clumps, and simultaneously spraying the material evenly into the soil along with the air. This achieves the function of spraying and deep loosening while walking, and spraying and mixing deep application. The leveling floor 23 backfills, levels, and compacts the trenches formed by the spray-explosion deep loosening rod 2 during the spray-explosion fertilization process, preventing the material from volatilizing into the air, causing waste and atmospheric pollution. Two limiting blocks 24 are used to re-bury the soil pushed away by the soil-breaking blade 16 back into the trenches. Then, the spray-explosion deep loosening rod creates a spray in the soil, allowing the material to be suspended and directionally spread into the soil. This achieves in-situ deep loosening of aging and compacted soil and protective no-till technology of directional spraying and mixing deep application of materials, improving the germination rate, survival rate, and growth effect of high-value crops. Example

[0145] This embodiment discloses a method for deep loosening and deep application of spray-and-blast soil for desert ecological restoration, including the following steps:

[0146] Step 1: Conduct on-site geological surveys and soil sampling in the original soil area. Then, based on the results of the on-site geological surveys and soil sampling, prepare the materials as follows:

[0147] Rare earth fertilizers refer to water-soluble salts of light rare earth element compounds (excluding radioactive substances such as uranium and thorium). Rare earth elements have a stimulating effect on plant growth; whether single or mixed, they exhibit effects similar to micronutrient fertilizers, such as increasing crop yield, accelerating crop maturity, and improving the quality of certain crops. In forestry and pasture planting areas, the use of appropriate amounts of rare earth elements can promote the growth and development of trees and pastures. Currently used agricultural rare earth compounds mainly include rare earth nitrates, rare earth ammonium bicarbonate compound fertilizers, rare earth molybdenum chelate fertilizers, and agricultural rare earth compound agents.

[0148] Water-retaining agents: A. Huahong water-retaining agent is a biodegradable organic polymer that can repeatedly absorb water. It can quickly absorb and store rainwater or irrigation water in the soil, thereby reducing water loss, and can also absorb moisture from the air. B. Baichuan water-retaining agent is a hydrogel-like polyglutamic acid water-retaining agent. In addition to its water-retaining function, it also has a certain fertilizer effect and can be diluted with fresh water before application.

[0149] Soil remediation agent: The soil remediation agent is obtained by mixing microbial liquid and soil conditioner in a 4:5 ratio. The microbial liquid contains compound bacterial agents, nitrogen-fixing rhizobia, phosphate-solubilizing bacteria, lactic acid bacteria, actinomycetes, Bacillus subtilis, rhizobium agents, nitrogen-fixing bacteria agents, phosphate-solubilizing microbial agents, silicate microbial agents, photosynthetic bacteria agents, organic material composting agents, growth-promoting agents, mycorrhizal fungi agents, bioremediation agents, etc. The main components of the soil conditioner are polymeric amino acids obtained from the hydrolysis of feathers and water-soluble fertilizer in a 5:4 ratio, with amino acids ≥150g / L and organic matter ≥1240g / L.

[0150] Solid filler: 250 kg of corn flour.

[0151] Liquid filler: fresh water.

[0152] Step 2: Set parameters. First, measure the porosity of the soil, and then set the penetration depth and blasting pressure according to the soil conditions. The equipment parameters are set as follows: penetration depth 40-60cm; pressure 0.8-1.2MPa; material quantity 30L / batch.

[0153] Step 3: Operation preparation: Load the material into the feed box 5, connect the tractor to the frame 1, and set the tractor speed;

[0154] Step 4: Loosening the soil and applying materials, spraying materials under positive pressure while walking.

[0155] Step four is as follows: Using integrated deep loosening and application equipment, the vehicle frame is first placed on the soil in the original soil area via its wheels. The deep loosening and application rods are then placed in the soil to a depth of 40-60cm. A trench is dug in the soil. The piston rod of the hydraulic cylinder 25 is then shortened, and the deep loosening rod 2 is placed in the trench. The hook 27 is then attached to the hook 26, and the pin is inserted into the pin hole. The deep loosening and application operation then begins. The drive mechanism 22 pulls the vehicle frame 1 forward, and the built-in sprayer... During its forward movement, the wings 28 of the blasting channel and material channel maintain a seal between the blasting hole 4 and the original soil area. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the blasting deep loosening rod 2, causing the blasting deep loosening rod 2 to vibrate high-frequency vibrations on the soil, which liquefies the soil near the soil-breaking blade 16. This reduces the resistance encountered by the blasting deep loosening rod 2 as it moves forward through the soil. Then, the controller controls the air compressor 9 to compress air into the energy storage tank 10, and the pressure transmitter 17 transmits the pressure of the compressed air in the energy storage tank 10. The system adjusts to provide the appropriate detonation pressure to the detonation canister 11. The controller controls the detonation solenoid valve 19 to open the detonation canister 11, and then the electric valve on the discharge pipe 6 is opened. The controller controls the rotary tongue 40 to block the first channel 37 and open the second channel 38, allowing the material to enter the bend of the detonation deep loosening rod 2 and temporarily accumulate in the detonation channel 3. Then, the rotary tongue 40 blocks the second channel 38 and opens the first channel 37. At this time, the detonation system generates a compressed air shock wave that enters the detonation deep loosening rod 2, thus detonating the material that has been temporarily stored in the deep loosening rod 2. The material is mixed with compressed air and then sprayed into the soil through the spray-explosion deep loosening rod 2, loosening the soil, breaking up compacted clumps, and simultaneously spraying the material evenly into the soil along with the air. This allows for simultaneous spray-explosion deep loosening and spray-mixing deep application while the operator is moving around. The leveling floor 23 backfills, levels, and compacts the trenches created by the spray-explosion deep loosening rod 2 during the spray-explosion fertilization process, preventing fertilizer from volatilizing into the air, causing waste and atmospheric pollution. Two limiting blocks 24 are used to re-fill the soil pushed away by the soil-breaking blade 16 back into the trenches. This achieves in-situ deep loosening of sandy soil and protective no-till technology for directional spray-mixing deep application of materials. After processing by this equipment, the growth and survival rate of sand-grown plants are promoted. Example

[0156] This embodiment discloses a method for deep loosening and deep application of spray-and-blast soil for the construction of high-standard farmland, including the following steps:

[0157] Step 1: Conduct on-site investigation and soil sampling of the original soil, and then configure materials based on the results of the on-site investigation and soil sampling.

[0158] Step 2: Adjust the length of the upper end of the spraying and deep loosening rods to 30-60cm to carry out deep loosening and modification of the plow pan in high-standard farmland;

[0159] Step 3: Load the bio-organic fertilizer and soil conditioner into the feed box 5 according to the ratio, connect the tractor to the frame 1, and set the speed of the tractor;

[0160] Step 4: The drive mechanism 22 pulls the frame 1 forward. The wing 28, which has a built-in explosion channel and material channel, keeps the explosion hole 4 sealed with the original soil area during the forward movement. The controller controls the compressed air of the air compressor to enter the energy storage tank. The pressure of the compressed air in the energy storage tank is adjusted by the pressure transmitter to provide the explosion tank with a suitable explosion pressure. The controller controls the explosion solenoid valve to open and close the explosion tank. Compressed air is generated by the explosion system and explodes in the soil through the explosion deep loosening rod, forming soil fissures and lifting the soil. At the same time, the feeding system continuously feeds the material into the explosion deep loosening rod together with the compressed air. Then, the explosion is formed in the soil through the explosion deep loosening rod, allowing the material to be suspended and directionally flowed into the soil to carry out deep loosening and transformation of the plow layer of high-standard farmland.

[0161] Step 5: Adjust the length of the upper end of the spraying and deep-loosening rods to 10-30cm to carry out deep-loosening and transformation of the topsoil of high-standard farmland;

[0162] Step 6: Prepare the topsoil material, which includes: biogas residue and biogas slurry, straw powder, bio-organic fertilizer, special soil conditioner, compound micronutrient fertilizer, etc., and place the prepared topsoil material in the feed box 5.

[0163] Step 7: The drive mechanism 22 pulls the frame 1 forward. The wing 28, which contains the detonation channel and material channel, maintains a seal between the detonation hole 4 and the original soil area during forward movement. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations acting on the detonation deep loosening rod 2, causing the rod to vibrate against the soil, liquefying the soil near the soil-breaking blade 16. This reduces the resistance encountered by the rod as it moves through the soil. Then, the controller controls the air compressor 9 to compress air into the storage tank 10. The pressure transmitter 17 adjusts the compressed air pressure in the storage tank 10 to provide a suitable detonation pressure to the detonation canister 11. The controller controls the detonation solenoid valve 19 to open the detonation canister 11, and then the electric valve on the discharge pipe 6 is opened. The controller controls the rotary tongue 40 to block the first channel 37. The second channel 38 opens, allowing material to enter the bend of the spray-blast deep loosening rod 2 and temporarily accumulate in the spray-blast channel 3. Then, the rotating tongue 40 blocks the second channel 38, opening the first channel 37. At this time, the spray-blast system generates a compressed air shock wave that enters the spray-blast deep loosening rod 2. The material temporarily stored in the spray-blast deep loosening rod 2 mixes with the compressed air, and then forms a spray-blast with material in the soil through the spray-blast deep loosening rod 2, loosening the soil, breaking up compacted clumps, and at the same time, the material is evenly sprayed into the soil along with the air. This achieves the function of spray-blast deep loosening and spray-mixing deep application while walking. The flat floor 23 backfills, levels, and compacts the trenches formed by the spray-blast deep loosening rod 2 during the spray-blast fertilization process, preventing fertilizer from volatilizing into the air, causing waste and air pollution. The two limiting blocks 24 are used to re-bury the soil pushed away by the soil-breaking blade 16 back into the trenches. Deep loosening is carried out on the topsoil of high-standard farmland.

[0164] Using this equipment to construct high-standard farmland can rapidly improve soil permeability, form granular structures, and increase the content of organic matter, nitrogen, phosphorus, potassium, and microorganisms in the soil within a short period (six months), enabling the soil to quickly meet the requirements for agricultural planting. Precise, targeted, and appropriate fertilization increases fertilizer utilization to over 80%. The use of agricultural organic waste (livestock manure, straw powder, biogas slurry, etc.) as fertilizer, the recycling of agricultural and livestock products, and the application of superior green manure through spraying, no-till reseeding can further reduce fertilizer costs. Example

[0165] This embodiment discloses a spray-and-explosion deep loosening and deep application method for topdressing in conservation tillage, including the following steps:

[0166] Step 1: Conduct on-site investigation and soil sampling of the original soil during the plant growth period. Then, based on the results of the on-site investigation and soil sampling, formulate material preparation, which includes nitrogen, potassium, and micronutrients:

[0167] Step 2: Set parameters. Set the penetration depth and detonation pressure according to the soil conditions to be operated on; penetration depth 10-30cm; pressure 0.8-1.2MPa; gas or liquid material flow rate 30L / s.

[0168] Step 3: Operation preparation: Load the material into the feed box 5, connect the tractor to the frame 1, and set the tractor speed;

[0169] Step 4: Loosening the soil and applying materials, spraying materials under positive pressure while walking.

[0170] Step four is as follows: Using integrated deep loosening and application equipment, the vehicle frame is first placed on the soil in the original soil area via its wheels. The deep loosening and application rods are then placed in the soil to a depth of 10-30cm. A trench is dug in the soil. The piston rod of the hydraulic cylinder 25 is then shortened, and the deep loosening rod 2 is placed in the trench. The hook 27 is then attached to the hook 26, and the pin is inserted into the pin hole. The deep loosening and application operation then begins. The drive mechanism 22 pulls the vehicle frame 1 forward, and the built-in sprayer... During its forward movement, the wings 28 of the blasting channel and material channel maintain a seal between the blasting hole 4 and the original soil area. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the blasting deep loosening rod 2, causing the blasting deep loosening rod 2 to vibrate high-frequency vibrations on the soil, liquefying the soil near the soil-breaking blade 16. This reduces the resistance encountered by the blasting deep loosening rod 2 as it moves forward through the soil. Then, the controller controls the air compressor 9 to compress air into the energy storage tank 10, and the pressure transmitter 17 transmits the compressed air pressure in the energy storage tank 10 to the... The system adjusts the pressure to provide the appropriate detonation pressure to the detonation canister 11. The controller then controls the detonation solenoid valve 19 to open the detonation canister 11. The electric valve on the discharge pipe 6 is then opened. The controller controls the rotary tongue 40 to block the first channel 37, opening the second channel 38. Material then enters the bend of the detonation deep loosening rod 2, temporarily accumulating in the detonation channel 3. The rotary tongue 40 then blocks the second channel 38, opening the first channel 37. At this point, the detonation system generates a compressed air shock wave that enters the detonation deep loosening rod 2, thus detonating the material temporarily deposited in the deep loosening rod 2. The material is mixed with compressed air and then sprayed into the soil through the spray-explosion deep loosening rod 2, forming a powdery material that loosens the soil, breaks up compacted clumps, and simultaneously sprays the material evenly into the soil along with the air. This allows for simultaneous spray-explosion deep loosening and spray-mixing deep application while walking. The leveling floor 23 backfills, levels, and compacts the trenches formed by the spray-explosion deep loosening rod 2 during the spray-explosion fertilization process, preventing fertilizer from volatilizing into the air, causing waste and atmospheric pollution. Two limiting blocks 24 are used to re-fill the soil pushed away by the soil-breaking blade 16 back into the trenches. This achieves protective tillage topdressing technology, supplying the large nutrient needs of crops at a certain stage or supplementing insufficient base fertilizer. Example

[0171] This embodiment discloses a method for deep loosening and deep application of spray-and-blast soil for the remediation of heavy metal pollution in agricultural land, comprising the following steps:

[0172] Step 1: Conduct on-site investigation and soil sampling of the original soil, and then prepare materials based on the results of the on-site investigation and soil sampling. The materials include an extract that is water-soluble in heavy metals.

[0173] Step 2: Set parameters. Set the penetration depth and blasting pressure according to the soil conditions to be operated on; penetration depth 30-50cm; pressure 0.8-1.2MPa; gas or liquid material volume 30L / s.

[0174] Step 3: Operation preparation: Load the material into the feed box 5, connect the tractor to the frame 1, and set the tractor speed;

[0175] Step four's specific process is as follows: Using a spray-type deep loosening and deep application integrated engineering equipment, first, place the vehicle frame on the original soil area via the wheels. Place the spray-type deep loosening rod and deep application rod in the soil to a depth of 30-50cm. Dig a trench in the soil. Then, shorten the piston rod of the hydraulic cylinder 25, and place the spray-type deep loosening rod 2 into the trench. Place the hook ring 27 onto the hook 26, and then insert the pin into the pin hole. Then, begin the spray-type deep loosening and deep application operation. The drive mechanism 22 pulls the vehicle frame 1 forward. During its forward movement, the wing 28, equipped with a detonation channel and a material channel, maintains a seal between the detonation hole 4 and the original soil area. The controller's high-frequency vibrator 7 continuously generates high-frequency vibrations that act on the detonation and loosening rod 2, causing the detonation and loosening rod 2 to vibrate against the soil, liquefying the soil near the soil-breaking blade 16. This reduces the resistance encountered by the detonation and loosening rod 2 as it moves through the soil. Then, the controller controls the air compressor 9 to compress air into the energy storage tank 10, and the compressed air in the energy storage tank 10 is transmitted through the pressure transmitter 17. The pressure is regulated to provide a suitable detonation pressure to the detonation canister 11. The controller controls the detonation solenoid valve 19 to open the detonation canister 11, and then the electric valve on the discharge pipe 6 is opened. The controller controls the rotary tongue 40 to block the first channel 37 and open the second channel 38, allowing the material to enter the bend of the detonation deep loosening rod 2 and temporarily accumulate in the detonation channel 3. Then, the rotary tongue 40 blocks the second channel 38 and opens the first channel 37. At this time, the detonation system generates a compressed air shock wave that enters the detonation deep loosening rod 2 and briefly resides in it. The material is mixed with compressed air and then sprayed into the soil through the spray-explosion deep loosening rod 2, loosening the soil, breaking up compacted clumps, and simultaneously spraying the material evenly into the soil along with the air. This achieves the function of spraying and deep loosening while walking, and spraying and mixing for deep application. The leveling floor 23 backfills, levels, and compacts the trenches formed by the spray-explosion deep loosening rod 2 during the spray-explosion fertilization process, preventing fertilizer from volatilizing into the air, causing waste and atmospheric pollution. Two limiting blocks 24 are used to re-fill the soil pushed away by the soil-breaking blade 16 back into the trenches. This achieves a protective no-till remediation technology for heavy metal pollution control in agricultural land.
