Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of soil improvement and remediation, and particularly relates to a spray-explosion type deep loosening and deep application engineering equipment and a working method thereof. BACKGROUND

[0002] Soil loosening and fertilization is an important operation in agricultural production. The main role of soil loosening is to increase the permeability of the plough layer of soil, enhance the exchange capacity of water, fertilizer, heat and air, and accelerate the formation of soil aggregate structure. The respiration of root system is enhanced, and the absorption of mineral elements by the root system is promoted.

[0003] In most cases, the soil cannot meet the demand of high yield in agriculture. Generally, 60-70% of the yield of crops is provided by the basic soil fertility, and the remaining 30-60% is provided by fertilization. Therefore, fertilization is an extremely important factor for high yield. Traditional soil loosening and fertilization are two operations. With the development of modern agricultural machinery, soil loosening and fertilization have been gradually combined. Here, the combination is the industrialized production of chemical fertilizers. However, the conventional organic fertilizer still needs to be spread by special machines or manually.

[0004] Patent No. CN105432168A discloses a pneumatic deep loosening and fertilizing machine, which comprises a frame, a deep loosening device, an air pump, a fertilizing device and a depth control device. The deep loosening device is arranged on both sides of the frame and fixed on the shovel handle frame. The fertilizing device and the air pump are arranged on the upper side of the frame, and the fertilizing device is arranged behind the air pump. The depth control device is arranged on both sides of the frame and located outside the side beam.

[0005] The scheme increases the air hole on the deep loosening shovel handle, which is communicated with the small hole of the shovel tip. Air is injected by the air compressor in the air pump, covers the shovel tip, penetrates into the plow bottom layer, loosens the soil, assists the shovel tip to break the harden block, plays a role of reducing resistance, slows down the damage degree of the shovel tip, expands the soil porosity, and promotes the absorption of fertilizer. However, the structure of this scheme only loosens the soil by pneumatic method. When the fertilizer is directly applied into the soil along the deep loosening shovel after loosening, the fertilizer is difficult to be uniformly applied around the plant root system, which is not conducive to the growth of the plant root system. Moreover, the fertilizer is accumulated in the ditch, which is easy to cause the seedling burning phenomenon. SUMMARY

[0006] The present application provides a spray-explosion type deep loosening and deep application engineering equipment and a working method thereof, which can solve the problem that the fertilizer cannot be uniformly spread into the soil in a larger range after loosening.

[0007] In order to achieve the above purpose, the present application provides a spray-explosion type deep loosening and deep application engineering equipment, which comprises a frame, a spray-explosion system, a spray-explosion deep loosening rod, a feeding system and a deep application rod. The frame is provided with walking wheels. The equipment is characterized in that,

[0008] The jet explosion deep loosening rod is provided with a jet explosion channel, and the lower end of the jet explosion deep loosening rod is provided with at least one jet explosion hole, the direction of the jet explosion hole is not towards the lower side, the upper end of the jet explosion channel is communicated with the air outlet of the jet explosion system through a pipeline, the lower end of the jet explosion channel is communicated with the jet explosion hole, the upper end of the jet explosion deep loosening rod and the jet explosion system are connected with the frame, and the jet explosion system is used for generating a compressed air shock wave and forming jet explosion through the jet explosion deep loosening rod,

[0009] The deep application rod is provided with a material application channel, the outlet of the material supply system is communicated with the material application channel at the upper end of the deep application rod through a material outlet pipe, the deep application rod is fixedly connected with the jet explosion deep loosening rod located in the front part of the deep application rod, the lower end of the deep application rod is provided with at least one first material outlet hole communicated with the material application channel, and the upper end of the deep application rod and the material supply system are connected with the frame.

[0010] The jet explosion deep loosening rod and the deep application rod are provided with triangular wings on the left and right sides of the upper end of the jet explosion deep loosening rod and the deep application rod.

[0011] The principle of the scheme is as follows: first, the frame is placed on the soil through the walking wheels, then the jet explosion deep loosening rod and the deep application rod are placed in the soil with a depth of 100 cm or less, the material supply system is filled with liquid material, solid-liquid mixed material or powder and particle material, then the frame is pulled forward by the self-driving power device or the driving mechanism, the wings provided with the jet explosion channel and the material channel keep the jet explosion hole sealed with the original soil during the forward movement, the jet explosion system generates a compressed air shock wave and forms jet explosion in the soil through the jet explosion deep loosening rod, soil cracks are formed, the soil is loosened, the hardening soil is broken, the degree of obstruction of the jet explosion deep loosening rod is reduced, the soil porosity is improved, after the jet explosion is completed and the soil is loosened, the soil that is jet exploded has not yet returned to the original position, and then the material supply system sprays the liquid material through the deep application rod to make the material uniformly sprayed in the loosened gap between the loosened soil cracks in front of the soil that has not yet returned to the original position, so that the functions of forward movement, jet explosion deep loosening and deep application mixing are integrated.

[0012] The beneficial effects of the scheme are as follows:

[0013] 1. High fertilizer utilization rate, the scheme sprays the fertilizer into the loosened soil, does not lose to the air to produce fertilizer loss and pollutes the atmosphere, does not flow away or blow away with surface runoff in the case of heavy rain and strong wind, produces water erosion and wind erosion, plant root system absorbs the fertilizer and roots in the soil, does not cause the root system of crops to float, the absorption nutrient capacity of the root system of crops and the ability to resist adverse environment are improved, and the influence of natural disasters such as diseases and pests is reduced. The wings are arranged, so that the spray holes on the wings form a better sealing effect with the soil, and the wings can make the spray range and the fertilizer application distance longer. If the wings are not arranged, the compressed air shock wave directly sprays at the side wall of the spray deep loosening rod, and through the arrangement of the wings, the compressed air shock wave sprays after passing through the width of the wings, and the spray distance is longer, and the fertilizer application is the same principle.

[0014] 2. The liquid fertilizer or material is positively suspended and sprayed through the feeding system and the deep application rod, the whole area covered by the plant root system can be loosened and fertilized, and after the soil is loosened by the gas shock wave, the feeding system and the deep application rod positively suspend and spray the liquid fertilizer or material through the material application hole, so that the material is uniformly sprayed in the loosened soil cracks, and the soil gaps are still present, so that the liquid fertilizer or material can reach a wider area, and the fertilizer application area is larger and more uniform.

[0015] 3. The scheme loosens the soil and applies the fertilizer while walking, and the loosening and fertilizing efficiency is improved. The working depth of the scheme is within 100 cm, so the crops with root system distributed within 100 cm can be applied, including wheat, corn, cotton and other field crops, and the scheme can also be applied to fruit trees, tea gardens, pasture, grassland, farmland heavy metal treatment, acidified soil treatment, desert water conservation, soil in-situ remediation and improvement scenarios. The surface soil is not turned over, which is of great significance to the northern drought and wind erosion area, reducing the source of sand dust and soil erosion. Not turning over the surface soil also reduces the evaporation surface area and the evaporation amount, which is beneficial to the preservation of soil moisture and nutrients.

[0016] 4、This scheme through the spray explosion deep loosening will crop root system distribution of all areas of a comprehensive loose soil, through the spray explosion also cut off the soil capillary, reduce capillary evaporation, benefit to conserve soil moisture, also can prevent and cure land salinization. Material application is more uniform, material under the action of compressed air, uniform suspension distribution in the lower layer of soil root system, reduce the air volatile loss, and induce root system to extend to the deep layer of soil, increase the distribution range of root system, make full use of soil deep layer nutrients, at the same time improve the plant stress resistance, so as to improve the input-output ratio. Low energy consumption, because it is in the lower layer of soil spray explosion, no strong mechanical resistance, the required power is much smaller than the traditional plow and rotary cultivator.

[0017] 5、Wide application range, can be applied to field, fruit, grassland repair, desertification control, desertification control, Chinese herbal medicine planting, soil remediation and other scenes, also can realize the organic waste fertilizer of biogas residue and biogas liquid. Application material selection is wide, fertilizer, organic fertilizer, biogas liquid, solid powder, water retaining agent, clay, fine sand, mineral powder, sawdust, straw powder and other flowable materials which can be used for soil remediation and improvement can be used.

[0018] 6、This equipment and operation method greatly improves the agricultural production efficiency, improves the soil ventilation condition, granular structure, soil ecology and chemical state, and the effect is rapid, covers most of the area of crop root system growth, improves the soil environment provided by the current crop to realize high yield.

[0019] 7、This scheme can place a large amount of organic fertilizer and beneficial microorganisms in the feeding system for field application, improve the soil ecological environment, repair and improve the soil, improve the basic fertility of the soil, and achieve the purpose of land reclamation. Year after year, the indicators of the soil are continuously improved, the land is more fertile with each plowing, and the organic waste such as contaminated feces is recycled, the last joint of circular agriculture is opened, through the circulation of planting and breeding, carbon oxygen cycle and carbon nitrogen cycle, so as to realize the large cycle of agriculture.

At the same time, during the high-frequency vibration process, the jet-blasting system sprays and blasts, generates a compressed air shock wave through the jet-blasting system, and forms a jet-blasting in the soil through the jet-blasting deep loosening rod to loosen the soil. Then, the feeding system uniformly sprays liquid fertilizer into the gap between the soil in front of the loosened soil and the soil that has not yet returned to its original position through the deep application rod under positive pressure suspension, and the jet-blasting deep loosening and jet-mixing deep application are carried out under the condition of high-frequency vibration, which reduces the resistance of forward movement and improves the work efficiency. The high-frequency vibrator is fixedly connected with the deep application rod. The high-frequency vibrator can directly act on the jet-blasting deep loosening rod and the deep application rod.

[0023] Beneficial effects: The energy storage tank is used for compressed air buffering and storage, and the pressure capacity is matched with the exhaust pressure and the exhaust capacity of the air compressor. The jet-blasting tank instantaneously releases compressed air with a certain pressure and air volume into the soil through the jet-blasting deep loosening rod to generate an impact wave and gas expansion to loosen the soil, break the hardened soil, and loosen the soil more widely and quickly.

[0029] Beneficial effects: Reduces the processing difficulty of deep loosening bark and saves costs.

[0030] Furthermore, the outer periphery of the deep tapping head is cone-shaped, and the deep tapping head extends outward to form radial triangular protrusions.

[0031] Beneficial effects: The radial triangular protrusions can reduce soil resistance and facilitate the advance of the deep loosening head.

There are multiple detonation holes, which are distributed along the left and right sides and the top side of the lower end of the detonation deep loosening rod.

[0033] Beneficial effects: Due to the high pressure and fast flow rate of the compressed gas injected into the deep loosening rod, the compressed air flow can easily be directed towards 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 distribute the compressed air in the deep loosening rod relatively evenly 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 bayonet joint, facilitating disassembly and installation.

[0036] 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.

[0037] Beneficial effects: The soil-breaking blades can reduce the resistance of the deep loosening rod, making its movement smoother.

[0038] Further, a pressure transmitter and an inflation solenoid valve can be arranged on the pipeline between the energy storage tank and the blasting tank, and the blasting tank is electrically connected with a blasting solenoid valve, and the pressure transmitter is arranged between the blasting solenoid valve and the blasting tank.

[0039] Beneficial effects: The compressed air in the air compression device enters the energy storage tank, and the pressure of the compressed air in the energy storage tank is adjusted by the pressure transmitter to provide appropriate blasting pressure for the blasting tank, and the blasting solenoid valve is used to open and close the blasting tank.

[0040] Further, the walking wheels include front wheels and rear wheels, and each of the front wheels and the rear wheels is provided with two, and the two front wheels and the rear wheels are symmetrically arranged along the center line of the frame, and the walking compaction wheels are arranged, and the width of the walking compaction wheels matches the target range of upward blasting.

[0041] Beneficial effects: The device facilitates better walking of the frame through the walking wheels, and the center line of the walking compaction wheels is located above the center line of the blasting hole, which can prevent the airflow of upward blasting from collapsing the soil and play a role in compaction, thereby making the range of upward blasting wider.

[0042] Further, the deep application rod is provided with a plurality of first discharge holes, and the plurality of first discharge holes are located on the left and right sides of the deep application rod.

[0043] Beneficial effects: The first discharge holes on the left and right sides of the deep application rod can positively pressurize and suspend the sprayed material into the soil cracks on both sides that have been blasted and deep loosened, so that the diffusion range of the material is smoother and wider.

[0047] Beneficial effects: The flat plate is used to backfill, compact and level the gully formed by the blasting and deep loosening rod and the deep application rod during the blasting and fertilization process, so as to prevent the material from being exposed and volatilized into the air and causing waste, and the two limiting blocks are used to bury the soil pushed away by the soil breaking blade back into the gully.

[0048] Further, a switch valve is arranged on the feeding pipe.

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.

[0051] 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 the second 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.

[0052] Furthermore, a method for deep loosening and application using a spray-blasting technique is also disclosed, employing the aforementioned device and comprising the following steps:

Since the high-pressure gas injected into the jet explosion deep loosening rod 2 has a large pressure and a fast flow rate, it is easy for the high-pressure gas flow to flow to the end of the jet explosion deep loosening rod 2, and the air of the jetting holes on the side wall of the jet explosion deep loosening rod 2 is insufficient. Therefore, through the action of the first conical flow divider 22, the high-pressure air in the jet explosion deep loosening rod 2 can be uniformly distributed to each jetting hole, and the balance and effect of the final soil loosening are ensured.

The second conical flow divider 24 can uniformly distribute the high-pressure material in the deep application rod 3 to each first material outlet hole 8, and ensure the balance and effect of the final fertilization.

[0085] The jet explosion deep loosening rod 2 is provided with a soil breaking blade 25, and the cutting edge of the soil breaking blade 25 is in the direction of the forward movement of the vehicle frame 1. The soil breaking blade 25 can reduce the resistance of the forward movement of the jet explosion deep loosening rod 2, and make the forward movement of the jet explosion deep loosening rod 2 more smooth.

[0090] The jet explosion deep loosening rod 2 and the deep application rod 3 are provided with wings 18 on the left and right sides, and the jet explosion hole 4 and the first discharge hole 8 both penetrate the wings 18. Through the wings 18, the distance of jet explosion and fertilization can be longer, if the wings 18 are not arranged, the compressed air directly jet explodes at the side wall of the jet explosion deep loosening rod 2, and through the wings 18, the compressed air jet explodes after passing through the distance of the width of the wings 18, and the distance of jet explosion is longer, and the same principle is applied to fertilization.

[0093] ​The flat floor 32 is hingedly arranged on the frame 1, and is matched with the ground surface.

[0094] The flat floor 32 is used for backfilling, compacting and leveling the gullies formed by the jetting and blasting deep loosening rod 2 and the deep application rod 3 in the jetting and blasting deep loosening and deep application process, preventing the material from volatilizing into the air to cause air pollution and waste, and the two limiting blocks 33 are used for re-burying the soil pushed away by the soil breaking blade 25 into the gullies.

[0095] The flat floor 32 is hingedly arranged on the frame 1 in a detachable manner, and is removed before or after operation, when the equipment needs to be transported. The material can be a soil heavy metal modifier for improving and repairing the soil with heavy metal content exceeding the standard value, or an input for saline-alkali soil repair for repairing saline-alkali soil. Two hydraulic cylinders 17 are arranged at the rear end of the tractor, and the piston rods of the two hydraulic cylinders 17 are hingedly arranged on the frame 1.

[0100] As shown in the accompanying drawings, Figure 5

[0105] Step S4: loosening and fertilizing, walking and jet-blasting soil loosening and fertilizing at the same time. Embodiment 2

[0106] As shown in the accompanying drawings, Figures 6-7 The difference between this embodiment and embodiment 1 is that it further includes a material supplementing system, which includes a material tank 38, a second hydraulic pump 41 and a conveying pipe 39. The second hydraulic pump 41, the upper end of the conveying pipe 39 and the material tank 38 are all installed on the frame. The two ends of the second hydraulic pump 41 are respectively communicated with the upper end of the conveying pipe 39 and the discharge port of the material tank 38. The length of the conveying pipe 39 matches the length of the deep application rod. The second discharge holes 40 are arranged on the left and right sides and the rear end of the end of the conveying pipe 39. The second discharge holes 40 on the left and right sides of the conveying pipe 39 correspond to the positions of the wings. The material tank 38 is used to hold liquid material.

[0107] ​When the width of the wing on the deep-loosening rod is greater than 10cm, the area where the wing 18 on the deep-loosening rod 3 passes cannot be sprayed with material, and the trench formed at the rear end of the deep-loosening rod 3 cannot be sprayed with material either. Therefore, by setting up the material box 38 and the conveying pipe 39, material can be sprayed on the area where the wing 18 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 39 under positive pressure by the second hydraulic pump 41, and then the material is sprayed from the second discharge hole 40 in the conveying pipe 39 into the gap left by the wing 18. 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 40, so that the area where the wing passes is also sprayed with material, and the spraying range is wider and more comprehensive. Example 3

[0108] As attached Figures 8-9 As shown, this embodiment differs from Embodiment 1 in that it also includes a feeding system. The feeding system includes a material box 38, a conveying pipe 39, a rotating motor 42, and a rotating shaft 44. The material box 38 contains powder or granular materials. 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 39 is rotatably and sealedly connected to the rotating shaft 44. The bottom of the rotating shaft 44 protrudes from the conveying pipe 39. 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 39, and the other part is located outside the conveying pipe 39. The rotating motor 42 is mounted on the frame. The material box 38 is connected to the conveying pipe 39. A discharge valve 43 is provided at the outlet of the material box 38. 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 18.

[0109] When the width of the wing on the deep-soil loosening rod is greater than 10cm, the area where the wing 18 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 material box 38 contains granular or powdered material, when the equipment is in operation, the controller opens the discharge valve 43 and controls the motor to rotate, so that the material enters the conveying pipe 39 from the material box 38. 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 the powdered material. The material is sprayed into the gaps left by the wing 18 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 by the deep-soil loosening rod 2 when it moves. In addition, when the material box 38 contains granular material, the high-speed rotating spiral blade 45 can also break up and throw the granular material. Example 4

[0110] The difference between this implementation and Example 1 is that multiple sets of spray-explosive deep loosening rods 2 and deep application rods 3 are provided, with multiple traveling compaction wheels 11 corresponding to them. The upper ends of the multiple sets of spray-explosive deep loosening rods 2 and deep application rods 3 are connected to the outlet of the spray-explosive tank 14 and the discharge port of the first hydraulic pump 16 via hoses. By setting multiple sets of spray-explosive deep loosening rods 2 and deep application rods 3, the range of spray-explosive deep loosening and deep application is increased, and the work efficiency is improved. Example 5

[0111] As attached Figure 10 As shown, this embodiment differs from Embodiment 1 in that the telescopic device includes a fixed block 36 and a spring 37. The frame 1 is provided with through holes that match the blasting deep loosening rod 2 and the deep application rod 3. The blasting deep loosening rod 2 and the deep application rod 3 are provided with multiple first grooves 35 from top to bottom. The multiple first grooves 35 are symmetrical on both sides of the center line of the blasting deep loosening rod 2 and the deep application rod 3. The frame 1 is provided with a second groove. One end of the spring 37 is fixed in the second groove, and the other end of the spring 37 is connected to the fixed block 36. The fixed block 36 matches the first groove 35. The end of the fixed block 36 is spherical. The upper end of the first groove 35 is shaped like a spherical groove that matches the end of the fixed block 36. The lower end of the first groove 35 is arc-shaped. The width of the second groove is greater than the width of the fixed block 36, which facilitates the blasting deep loosening rod 2 and the deep application rod 3 to move back and forth.

[0112] When the soil conditions vary, 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 36 is squeezed, it enters the second groove. When the appropriate height is adjusted, the fixing block 36 enters the first groove 35, 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 36 can slide in the second groove, when the high-frequency vibrator 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 6

As the equipment quickly advances, the jet explosion deep loosened soil has not yet returned to the original position, and the material supply system immediately sprays the material through the deep application rod positive pressure suspension to uniformly spray the material in the loosened gap between the soil cracks in front of the soil that has not yet returned to the original position, so that the in-situ deep loosening and material directional jet mixing deep application of the hardening land are realized. Moreover, the jet explosion holes on the wings form a better sealing effect with the soil, and the distance between the jet explosion and the fertilization is longer.

[0125] Due to the local climate, rainwater is scarce, and water supply can only be produced by means of Yellow River water diversion or well water flooding, and the alfalfa land cannot be plowed and loosened after sowing, and the fertilizer is completely applied on the ground. After years of planting, the soil has been extremely hard, some plots have been seriously reversed, the alfalfa seedling mortality rate has soared year by year, the fertilizer utilization rate is extremely low, and other problems. The equipment realizes the jet explosion deep loosening and material directional jet mixing deep application technology of the grassland and the hardening alfalfa land, increases the height of the pasture alfalfa, reduces the mortality rate of the alfalfa plants, guarantees the plot seedling base, improves the yield of the alfalfa grass, improves the dry matter accumulation, and thus improves the planting benefit of the pasture.
