Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, and in particular to a soil acidification synergistic remediation device based on integrated water and fertilizer management. Background Technology

[0002] Soil acidification is a significant issue affecting agricultural production and the improvement of arable land quality. Long-term application of chemical fertilizers, nutrient leaching, and organic matter depletion can lead to an imbalance in soil pH, reducing available nutrients, degrading soil structure and properties, and impacting crop root growth. Current methods for remediating acidified soils typically include applying soil conditioners, regulating water and fertilizer application, and mechanical tillage. However, most existing remediation equipment is designed for single operational steps, making it difficult to achieve continuous and coordinated operations between tillage, fertilization, and soil mixing.

[0003] Existing fertigation equipment typically employs a fixed spraying structure for acidified soil remediation. This means the spraying area remains relatively fixed during equipment movement, leading to variations in water and fertilizer coverage across different areas. This results in some soil sections not fully contacting the amendment components, reducing the uniformity of the remediation process. Furthermore, the amendments or fertilizer components in the fertigation solution are prone to sedimentation and stratification during storage, causing unstable water and fertilizer concentrations during transport and negatively impacting soil remediation effectiveness.

[0004] In addition, existing tillage equipment and water and fertilizer application equipment are usually independent of each other. The tilled soil cannot be fully mixed with the sprayed water and fertilizer in a timely manner, and some of the amendments tend to remain on the soil surface, resulting in reduced utilization. On the other hand, using manual or multi-equipment combined treatment methods has problems such as low operation efficiency, high equipment investment costs, and insufficient continuity of the treatment process.

[0005] Therefore, there is an urgent need for a soil acidification synergistic treatment device based on water and fertilizer integration that can achieve soil loosening, uniform water and fertilizer spraying, dynamic water and fertilizer mixing, and synchronous soil disturbance after spraying on a single device, so as to improve water and fertilizer utilization efficiency and the effect of acidified soil treatment. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil acidification synergistic treatment device based on integrated water and fertilizer management.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a soil acidification synergistic treatment device based on integrated water and fertilizer management, comprising a vehicle body, and further comprising:

[0008] A tillage assembly, the tillage assembly including a tillage claw and a drive mechanism for driving the tillage claw to lift, lower and rotate;

[0009] The water and fertilizer tank is fixed to the vehicle body and has a disturbance component inside, and an air pump is fixedly installed on the outside.

[0010] The disturbance component includes a rotating rod, a stirring plate, and a disturbance disk. The rotating rod is rotatably installed inside the water and fertilizer tank, the stirring plate is fixedly installed on the rotating rod, and the disturbance disk is movably installed on the rotating rod.

[0011] The vehicle body is equipped with a spraying assembly, a reciprocating assembly, and a soil loosening blade. The spraying assembly is movably installed at the front end of the vehicle body, and the soil loosening blade is movably installed at the rear end of the vehicle body. The reciprocating assembly drives the spraying assembly and the soil loosening blade to reciprocate, so that the soil is turned over simultaneously during the water and fertilizer spraying process, thereby improving the uniformity of contact between water and fertilizer and acidified soil.

[0012] Preferably, the drive mechanism includes a mounting frame, motor A, a threaded rod, a drive plate, a U-shaped frame, motor B, and a rotating shaft; the mounting frame is fixed to the vehicle body, motor A is mounted on the mounting frame, and the output end of motor A is drivenly connected to the threaded rod; the drive plate is threadedly connected to the threaded rod, and the U-shaped frame is fixedly connected to the drive plate; motor B is mounted on the U-shaped frame, and the output end of motor B is drivenly connected to the rotating shaft; the throwing claws are in multiple sets, fixedly and spaced on the outer wall of the rotating shaft.

[0013] Preferably, the spraying assembly includes a water pump, a spray pipe, and a nozzle. The inlet of the water pump is connected to the inside of the water and fertilizer tank through a water pumping pipe, and the outlet is connected to the spray pipe. The nozzle is installed on the spray pipe.

[0014] Preferably, the reciprocating assembly includes a motor C, a transmission rod, a missing gear, an internal gear ring, and a connecting rod. The motor C and the transmission rod are connected by a first synchronous pulley set. The missing gear is fixed on the transmission rod and intermittently meshes with the internal gear ring. The internal gear ring is connected to the spray nozzle through the connecting rod. The intermittent meshing of the missing gear and the internal gear ring causes the spray nozzle to move periodically back and forth, thereby expanding the spray coverage area.

[0015] Preferably, the reciprocating assembly further includes a fixed block A and a fixed block B, the transmission rod is rotatably mounted on the fixed block A, and the internal gear ring is slidably mounted on the fixed block B.

[0016] Preferably, the rotating rod is connected to the motor C via a second synchronous pulley set. A part of the rotating rod is provided with a bidirectional thread. The disturbance plate is fitted with the bidirectional thread through a limiting structure and can be reciprocated along the axial direction of the rotating rod and installed in the water-fertilizer tank. The reciprocating movement of the disturbance plate creates axial disturbance inside the water-fertilizer tank, thereby improving the uniformity of water-fertilizer solution mixing.

[0017] Preferably, the limiting structure includes a limiting block and a limiting groove. The limiting block is fixed on the rotating rod, and the limiting groove is axially opened on the inner wall of the water and fertilizer tank. The outer wall of the disturbance plate is slidably fitted in the limiting groove. The outer wall of the rotating rod is fitted with a telescopic sleeve, and the telescopic sleeve is fixed between the disturbance plate and the limiting block.

[0018] Preferably, the water inlet end of the pumping pipe is provided with a filter plate, and the bottom of the agitator is in contact with the surface of the filter plate.

[0019] Preferably, the rotating rod has a hollow structure, and the air outlet of the air pump is rotatably connected to one end of the rotating rod through a pipeline.

[0020] Preferably, there are multiple stirring plates, which are distributed at intervals along the circumference and axial direction of the rotating rod, and each stirring plate is provided with a nozzle.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This invention utilizes a gear that, during rotation, drives an internal gear ring to reciprocate linearly. This reciprocating motion of the internal gear ring simultaneously drives a connected rod, which in turn drives the spray pipe and the nozzle mounted on it to reciprocate as well. This back-and-forth spraying pattern effectively avoids the uneven spraying problem that often occurs with single-pass spraying, ensuring that water and fertilizer evenly cover the soil area to be treated. Simultaneously, the back-and-forth turning action of the loosening blade promptly loosens and mixes the sprayed soil, breaking up surface compaction and allowing the sprayed water and fertilizer to quickly penetrate into the soil, fully contacting and evenly mixing with the acidified soil. This effectively enhances the neutralization and remediation effect of water and fertilizer on acidified soil, preventing evaporation and loss due to fertilizer remaining on the soil surface, and further ensuring the uniformity of soil acidification treatment.

[0023] 2. This invention uses the reciprocating movement of a disturbance disc to create back-and-forth disturbance in the water-fertilizer solution, which works synergistically with the basic stirring of the mixing plate to effectively enhance the water-fertilizer mixing effect and prevent the precipitation and stratification of solutes in the solution. Simultaneously, as the disturbance disc reciprocates axially, its bottom remains in close contact with the filter plate on the surface of the pumping pipe. The reciprocating motion of the disturbance disc continuously scrapes and cleans the surface of the filter plate, promptly removing accumulated impurities and effectively preventing clogging, thus ensuring the smooth flow of water and fertilizer. Furthermore, the air pump generates gas to further agitate the water-fertilizer solution with bubbles, which not only further improves the uniformity of the water-fertilizer mixture but also effectively increases the dissolved oxygen content of the solution, accelerating the dissolution rate of the amendment in the water-fertilizer.

[0024] 3. This invention drives the rotating shaft to rotate at high speed through the output end of motor B. When the rotating shaft rotates, it drives multiple sets of turning and throwing claws fixed at intervals on its outer wall to rotate synchronously. The rotation of the turning and throwing claws fully turns and loosens the soil to be treated, breaking up the compacted state of the soil surface and creating favorable conditions for the subsequent penetration and diffusion of water and fertilizer solutions. At the same time, motor A can be flexibly started and stopped according to the actual soil treatment needs. By adjusting the rotation direction and rotation amount of the threaded rod, the lifting and lowering amplitude of the drive plate can be controlled, thereby flexibly adjusting the downward movement depth of the turning and throwing component to adapt to the soil acidification treatment needs of different depths.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0036] See Figures 1 to 8 As shown, the present invention provides a soil acidification synergistic treatment device based on integrated water and fertilizer management, including a vehicle body 1, and further comprising:

[0037] A tillage assembly, comprising a tillage claw 27 and a drive mechanism for driving the tillage claw 27 to lift and rotate;

[0038] The water and fertilizer tank 31 is fixed to the vehicle body 1 and has a disturbance component inside, and an air pump 5 is fixedly installed on the outside.

[0039] The disturbance component includes a rotating rod 41, a stirring plate 42, and a disturbance disk 45. The rotating rod 41 is rotatably installed inside the water and fertilizer tank 31, the stirring plate 42 is fixedly installed on the rotating rod 41, and the disturbance disk 45 is movably installed on the rotating rod 41.

[0040] It should be noted that, for reference Figures 3 to 5As shown, the process begins with the water pump 32 being started. Under the suction of the water pump 32, the pre-prepared water-fertilizer solution inside the water-fertilizer tank 31 is transported to the spray pipe 33 through the water pipe 313. Subsequently, it is evenly sprayed onto the surface of the acidified soil to be treated through multiple sets of nozzles 34 installed on the spray pipe 33. Simultaneously, the motor C35 is started. The output of the motor C35 transmits power to the transmission rod 37 through the first synchronous pulley set 6, causing the transmission rod 37 to rotate stably. The missing gear 38, fixed on the transmission rod 37, rotates synchronously with the transmission rod 37. Because the missing gear 38 and the internal gear ring 39 use an intermittent meshing engagement method, the missing gear 38 drives the internal gear ring 39 to reciprocate linearly during rotation. The reciprocating motion of the internal gear ring 39 synchronously drives the connecting rod 311 connected to it to reciprocate, which in turn drives the spray pipe 33 and the components mounted on the spray pipe 33. The nozzles 34 move back and forth together, achieving reciprocating spraying. At the same time, the inner toothed ring 39 drives the loosening blade 312 fixed on one side to reciprocate, completing the turning over of the sprayed soil. Thus, the reciprocating spraying mode of the nozzles 34 effectively avoids the uneven problem of insufficient local spraying that is prone to occur in single-pass spraying, ensuring that water and fertilizer can be evenly covered in the soil area to be treated, laying a uniform water and fertilizer foundation for soil acidification remediation. Meanwhile, the reciprocating turning over of the soil with water and fertilizer can loosen and stir the sprayed soil in time, breaking up the soil surface compaction, and promoting the rapid penetration of the sprayed water and fertilizer into the soil interior, fully contacting and evenly mixing with the acidified soil, effectively improving the neutralization and remediation effect of water and fertilizer on acidified soil, avoiding the evaporation and loss caused by water and fertilizer remaining on the soil surface, and further ensuring the uniformity of soil acidification treatment.

[0041] The vehicle body 1 is equipped with a spraying component, a reciprocating component, and a soil loosening blade 312. The spraying component is movably installed at the front end of the vehicle body 1, and the soil loosening blade 312 is movably installed at the rear end of the vehicle body 1. The reciprocating component drives the spraying component and the soil loosening blade 312 to achieve reciprocating motion, so that the soil is turned over simultaneously during the water and fertilizer spraying process, thereby improving the uniformity of contact between water and fertilizer and acidified soil.

[0042] It should be noted that, for reference Figures 5 to 7As shown, when motor C35 starts and begins to rotate, it transmits power to rotating rod 41 through the second synchronous belt pulley group 7, causing rotating rod 41 to rotate synchronously. During the rotation of rotating rod 41, it will drive the stirring plate 42 fixed on its surface to rotate together, first performing basic mixing and stirring of the water and fertilizer solution inside water and fertilizer tank 31; since the outer wall of rotating rod 41 has a bidirectional thread, and the agitator 45 is limited by the limiting groove 44 on the inner wall of water and fertilizer tank 31, when rotating rod 41 rotates, it will drive the agitator 45 to move back and forth along the axial direction of rotating rod 41, through the agitator 45 The reciprocating movement of the 45 plate creates a disturbance in the water-fertilizer solution in the front-to-back direction, which works synergistically with the basic stirring of the mixing plate 42 to effectively enhance the water-fertilizer mixing effect and prevent the precipitation and stratification of solutes in the water-fertilizer solution. At the same time, as the 45 plate moves back and forth along the axial direction, its bottom is always in close contact with the filter plate on the surface of the pumping pipe 313. With the help of the reciprocating movement of the 45 plate, the surface of the filter plate can be continuously scraped and cleaned, and the impurities accumulated on the filter plate can be removed in time, effectively preventing the filter plate from clogging and ensuring the smooth flow of water-fertilizer delivery channels.

[0043] In addition, during the process of stirring and mixing the water and fertilizer inside the water and fertilizer tank 31, the air pump 5 is started simultaneously. The air pump 5 delivers the generated gas to the hollow rotating rod 41. After the gas flows inside the rotating rod 41, it is evenly sprayed out through the nozzle 47 on the surface of the stirring plate 42. The sprayed gas forms tiny bubbles, which further agitate the water and fertilizer solution. This not only further improves the uniformity of water and fertilizer mixing, but also effectively increases the dissolved oxygen content of the water and fertilizer solution and accelerates the dissolution rate of the amendment in the water and fertilizer.

[0044] In an optional embodiment, the drive mechanism includes a mounting frame 21, a motor A22, a threaded rod 23, a drive plate 28, a U-shaped frame 24, a motor B25, and a rotating shaft 26. The mounting frame 21 is fixed to the vehicle body 1, the motor A22 is mounted on the mounting frame 21, and the output end of the motor A22 is drivenly connected to the threaded rod 23. The drive plate 28 is threadedly connected to the threaded rod 23, and the U-shaped frame 24 is fixedly connected to the drive plate 28. The motor B25 is mounted on the U-shaped frame 24, and the output end of the motor B25 is drivenly connected to the rotating shaft 26. Multiple sets of throwing claws 27 are fixedly arranged at intervals on the outer wall of the rotating shaft 26.

[0045] It should be noted that, for reference Figures 1 to 2 As shown, this device can be flexibly applied to soil acidification remediation scenarios such as acidified red soil farmland in the south, plastic greenhouses for facility agriculture, and economic crop planting areas in orchards and tea gardens. It is suitable for large-scale operations on large contiguous land areas and refined remediation of small, scattered plots. In practical applications, the device's operating parameters can be flexibly adjusted according to the soil acidification depth and crop type in different scenarios to achieve integrated water and fertilizer management of soil acidification.

[0046] First, the entire device is moved to the area of ​​soil requiring treatment. Whether it's acidified red soil in southern China, greenhouse agriculture, tea gardens, or orchards, the vehicle body 1 allows for flexible movement to adapt to different site requirements. Then, based on the acidification depth of the soil to be treated, such as shallowly acidified greenhouse soil or deeply acidified outdoor farmland, motor A22 is started. After starting, motor A22 drives the threaded rod 23 connected to its output end to rotate synchronously. Because the drive plate 28 and the threaded rod 23 are connected by a thread, and are guided by the mounting frame 21, the rotation of the threaded rod 23 causes the drive plate 28 to move smoothly downwards along the axial direction of the threaded rod 23. During this downward movement, the drive plate 28 simultaneously moves the U-shaped frame 24 downwards, which in turn drives the turning claw 27 mounted on the rotating shaft 26 to move downwards until the turning claw 27 reaches its destination. The preset tillage depth; after the turning claw 27 is adjusted to the appropriate depth, the motor B25 is started. The output end of the motor B25 drives the rotating shaft 26 to rotate at high speed. When the rotating shaft 26 rotates, it will drive the multiple sets of turning claws 27 fixed at intervals on its outer wall to rotate synchronously. Through the rotation action of the turning claws 27, the soil to be treated is fully turned and loosened, breaking the surface compaction of the soil and creating good conditions for the subsequent penetration and diffusion of water and fertilizer solutions. At the same time, the motor A22 can be flexibly started and stopped according to the actual soil treatment needs. By adjusting the rotation direction and rotation amount of the threaded rod 23, the lifting and lowering amplitude of the drive plate 28 is controlled, thereby flexibly adjusting the downward movement depth of the turning component to adapt to the soil acidification treatment needs at different depths.

[0047] In an optional embodiment, the spraying assembly includes a water pump 32, a spray pipe 33, and a nozzle 34. The inlet of the water pump 32 is connected to the inside of the water and fertilizer tank 31 through a water pumping pipe 313, and the outlet is connected to the spray pipe 33. The nozzle 34 is installed on the spray pipe 33.

[0048] In an optional embodiment, the reciprocating assembly includes a motor C35, a transmission rod 37, a missing gear 38, an internal gear ring 39, and a connecting rod 311. The motor C35 and the transmission rod 37 are connected by a first synchronous pulley set 6. The missing gear 38 is fixed on the transmission rod 37 and intermittently meshes with the internal gear ring 39. The internal gear ring 39 is connected to the nozzle 33 through the connecting rod 311. Through the intermittent meshing of the missing gear 38 and the internal gear ring 39, the nozzle 33 moves periodically back and forth to expand the spray coverage area.

[0049] In an optional embodiment, the reciprocating assembly further includes a fixed block A36 and a fixed block B310, with the transmission rod 37 rotatably mounted on the fixed block A36 and the internal gear ring 39 slidably mounted on the fixed block B310.

[0050] In an optional embodiment, the rotating rod 41 is connected to the motor C35 via a second synchronous pulley set 7. Part of the rotating rod 41 is provided with a bidirectional thread. The disturbance disk 45 is installed in the water and fertilizer tank 31 by means of a limiting structure and the bidirectional thread. It can be reciprocated along the axis of the rotating rod 41. The reciprocating movement of the disturbance disk 45 causes axial disturbance inside the water and fertilizer tank 31, thereby improving the uniformity of water and fertilizer solution mixing.

[0051] In an optional embodiment, the limiting structure includes a limiting block 43 and a limiting groove 44. The limiting block 43 is fixed on the rotating rod 41, and the limiting groove 44 is axially opened on the inner wall of the water and fertilizer tank 31. The outer wall of the disturbance disk 45 is slidably fitted in the limiting groove 44. The outer wall of the rotating rod 41 is fitted with a telescopic sleeve 46, which is fixed between the disturbance disk 45 and the limiting block 43.

[0052] In an optional embodiment, the inlet end of the water pump 313 is provided with a filter plate, and the bottom of the agitator 45 is in contact with the surface of the filter plate to scrape and clean the filter plate during reciprocating movement.

[0053] In an optional embodiment, the rotating rod 41 has a hollow structure, and the air outlet of the air pump 5 is rotatably connected to one end of the rotating rod 41 through a pipeline.

[0054] In an optional embodiment, there are multiple stirring plates 42, which are distributed at intervals along the circumference and axial direction of the rotating rod 41, and each stirring plate 42 is provided with a nozzle 47.

[0055] Working principle: First, the entire device is moved to the area of ​​soil to be treated. Then, according to the required acidification depth of the soil to be treated, motor A22 is started. After motor A22 starts, it drives the threaded rod 23 connected to its output end to rotate synchronously. Since the drive plate 28 and the threaded rod 23 are connected by a thread, and are limited and guided by the mounting frame 21, the rotation of the threaded rod 23 will drive the drive plate 28 to move smoothly downward along the axial direction of the threaded rod 23. During the downward movement of the drive plate 28, the U-shaped frame 24 will move downward together. The U-shaped frame 24 will drive the turning claws 27 installed on the rotating shaft 26 to move downward synchronously until the turning claws 27 reach the preset turning depth. When the turning claws 27 are adjusted to the appropriate depth, motor B25 is started. The output end of motor B25 drives the rotating shaft 26 to rotate at high speed. When the rotating shaft 26 rotates, it will drive the multiple sets of turning claws 27 fixed at intervals on its outer wall to rotate synchronously. Through the rotation of the turning claws 27, the soil to be treated is fully turned and loosened.

[0056] The water pump 32 is started. Under the suction action of the water pump 32, the pre-prepared water-fertilizer solution inside the water-fertilizer tank 31 is transported to the spray pipe 33 through the water pipe 313. Then, it is evenly sprayed onto the surface of the acidified soil to be treated through multiple sets of nozzles 34 installed on the spray pipe 33. At the same time, the motor C35 is started synchronously. The output end of the motor C35 transmits power to the transmission rod 37 through the first synchronous pulley set 6, driving the transmission rod 37 to rotate stably. The gear 38 fixed on the transmission rod 37 will rotate synchronously with the transmission rod 37. The missing gear 38 and the internal gear ring 39 are engaged in an intermittent meshing manner. During the rotation of the missing gear 38, the internal gear ring 39 will drive the internal gear ring 39 to reciprocate linearly. When the internal gear ring 39 reciprocates, it will synchronously drive the connecting rod 311 connected to it to reciprocate. Then, the connecting rod 311 will drive the nozzle 33 and the nozzle 34 installed on the nozzle 33 to reciprocate together, realizing the reciprocating spraying operation of the nozzle 34. At the same time, the internal gear ring 39 will also drive the soil loosening blade 312 fixed on one side to reciprocate synchronously, completing the turning operation of the sprayed soil.

[0057] When motor C35 starts and begins to rotate, it transmits power to rotating rod 41 through the second synchronous belt pulley group 7, causing rotating rod 41 to rotate synchronously. During the rotation of rotating rod 41, it will drive the stirring plate 42 fixed on its surface to rotate together, first performing basic mixing and stirring of the water and fertilizer solution inside water and fertilizer tank 31. Since the outer wall of rotating rod 41 has a bidirectional thread and the disturbance plate 45 is limited by the limiting groove 44 on the inner wall of water and fertilizer tank 31, when rotating rod 41 rotates, it will drive disturbance plate 45 to move back and forth along the axis of rotating rod 41. The back and forth movement of disturbance plate 45 will create a disturbance in the water and fertilizer solution in the front and back directions, which will work together with the basic stirring of stirring plate 42 to effectively enhance the water and fertilizer mixing effect.

[0058] In addition, during the process of stirring and mixing the water and fertilizer inside the water and fertilizer tank 31, the air pump 5 is started simultaneously. The air pump 5 delivers the generated gas to the hollow rotating rod 41. After the gas flows inside the rotating rod 41, it is evenly sprayed out through the nozzle 47 on the surface of the stirring plate 42. The sprayed gas forms tiny bubbles, which further agitate the water and fertilizer solution. This not only further improves the uniformity of water and fertilizer mixing, but also effectively increases the dissolved oxygen content of the water and fertilizer solution and accelerates the dissolution rate of the amendment in the water and fertilizer.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
