Description

Technical Field

[0001] This invention relates to the field of agricultural implements technology, and more specifically, to a highly efficient device for improving saline-alkali dryland. Background Technology

[0002] Saline-alkali dryland refers to a non-paddy field (i.e., not long-term flooded) agricultural production system carried out on saline-alkali soil. This type of land typically suffers from high pH, ​​high sodium ion concentration, soil compaction, and poor water and fertilizer retention. When the soluble salt content or alkalinity in the soil exceeds limits, traditional crops struggle to grow normally. Saline-alkali dryland is mainly distributed in arid and semi-arid regions, such as river valleys and plains in basins and various depressions. In these areas, groundwater is shallow, flow is poor, and mineralization is high. During spring and autumn, as soil moisture evaporates, salt remains on the surface, forming secondary salinized soil. The formation of saline-alkali dryland is closely related to groundwater. High groundwater levels and high groundwater mineralization are internal factors contributing to soil salinity, while climatic conditions where evaporation far exceeds precipitation are external factors.

[0003] There are several measures for improving saline-alkali dryland. Open ditch drainage involves establishing a drainage system in areas with heavy salinity, shallow groundwater levels, and available drainage outlets. Open ditches are dug to a depth below the groundwater level, and irrigation water is used to wash away the salt. The lateral seepage force of the farmland soil layer allows the dissolved salt water in the soil to seep into the ditches and be discharged from the farmland. Underground pipe drainage uses irrigation water and rainwater to flush and desalinate the saline soil layer above the underground pipe, removing excessive salt from the soil and accelerating the desalination process. At the same time, the groundwater level is controlled at a suitable depth to prevent the soil from returning salt. Land leveling and deep plowing break up the plow pan, increase soil permeability, improve soil structure, and accelerate salt leaching.

[0004] In existing technologies, due to the uneven distribution of salt in saline-alkali soil, if the ground is uneven after deep plowing, "high-alkali depressions" are easily formed during irrigation or rainfall. The soil at higher elevations has a thin water layer, resulting in poor salt leaching. Long-term accumulation will lead to the expansion of salt spots. Low-lying areas will suffer from waterlogging due to poor drainage. At the same time, salt will migrate upward with the evaporation of water, exacerbating surface salinization. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of this invention is to provide an efficient device for improving saline-alkali dryland.

[0006] To solve the above problems, the present invention adopts the following technical solution, which can realize the automatic adjustment of the position of the roller according to the real-time elevation difference of the ground surface, increase the compaction and push of saline soil in high places, and raise the roller in low-lying areas to avoid excessive compaction, thereby preventing the phenomenon of "high alkali depression and waterlogging" caused by uneven ground after deep plowing of alkaline land.

Multiple drill rods are provided on the lower side of the drive platform. A controller is fixedly connected to the front side of the machine body. A soil leveling component is provided on the outer side of the machine body and the drive platform. The leveling component includes two first hinge seats fixedly connected to the upper side of the machine body, two second hinge seats fixedly connected to the upper side of the drive platform, a first cylinder is hinged together between the first and second hinge seats, the telescopic end of the first cylinder is hinged to the second hinge seats, two third hinge seats are fixedly connected to the lower side of the machine body, a connecting plate is hinged inside the third hinge seats, a support frame is fixedly connected to the left side of the connecting plates on both the front and rear sides, a movable groove is opened through the lower side of the inner side of the support frame, an installation frame is slidably connected inside the movable groove, and a roller is rotatably connected to the lower side of the inner side of the installation frame; An adjustment assembly is provided on the outside of the body. The adjustment assembly includes a limiting plate fixedly connected to the front and rear sides of the mounting frame. The limiting plate is slidably connected inside the movable groove, which is cross-shaped.

[0008] Furthermore, a connecting frame is provided on the upper part of the machine body. The connecting frame is L-shaped, and flanges are fixedly connected to both ends of the connecting frame. The flange on the lower side of the vertical part of the connecting frame is bolted to the upper side of the machine body.

[0009] Furthermore, the upper sides of the connecting plate and the support frame are both fitted to the lower side of the machine body, the shape of the movable groove is adapted to the shape of the mounting frame, and an external laser leveling sensor is provided at the lower front end of the machine body for real-time collection of ground elevation data and transmission to the controller.

[0010] Furthermore, an electric push rod is fixedly connected to the upper side of the inner side of the movable groove, and the telescopic end of the electric push rod is fixedly connected to the upper side of the limiting plate.

[0011] Furthermore, a plurality of fourth hinge seats are fixedly connected to the left side of the machine body, and a plurality of fifth hinge seats are fixedly connected to the upper side of the support frame. A second cylinder is hinged together between the fourth and fifth hinge seats, and the extension and retraction end of the second cylinder is hinged to the fifth hinge seat.

[0012] Furthermore, the inner and outer sides of the mounting frame are provided with a soil cleaning component, which includes multiple protrusions fixedly connected to the outer side of the roller.

[0013] Furthermore, the lower side of the mounting frame is fixedly connected with multiple peeling teeth, and the multiple peeling teeth and multiple protrusions are arranged alternately.

[0014] Furthermore, the inner and outer sides of the machine body are provided with a water injection component, which includes a water storage cavity opened inside the machine body.

[0015] Furthermore, a water injection pipe is fixedly connected to the upper side of the machine body, and the water injection pipe extends into the interior of the water storage chamber. Multiple conveying pipes are fixedly connected to the lower side of the machine body, and the conveying pipes are connected to the water storage chamber. A nozzle is fixedly connected to the bottom end of the conveying pipe. A fixing plate is fixedly connected to the lower right side of the machine body. A spiked rake is fixedly connected to the lower side of the fixing plate. The spiked rake is fixed below the fixing plate and is located behind the machine body in the direction of travel.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention uses a drill rod to break up the soil, and then a roller to flatten the broken soil. Since the roller can automatically adjust its position according to the real-time height difference of the ground surface, it can increase the rolling and pushing of saline soil in high places and raise the roller in low places to avoid excessive compaction, thus realizing dynamic leveling of "cutting high and filling low" and preventing the phenomenon of "high alkali and low water" caused by uneven ground after deep plowing of alkali land.

[0017] (2) The present invention adjusts the height of the installation frame by means of an electric push rod and a second cylinder to adapt to different terrains. At the same time, due to the sliding structure of the cross-shaped movable groove and the limiting plate, the installation frame can be finely adjusted within the support frame to adapt to extremely complex terrains such as local pits, ruts, and salt spot accumulation areas in saline-alkali land. When a low-lying and soft area is detected, the installation frame can be quickly raised to effectively prevent secondary compaction of the soil and protect the soil structure of the improved area.

[0018] (3) The present invention breaks the compacted soil into small pieces by setting protrusions, and at the same time cleans the soil on the surface of the roller with the help of peeling teeth. Since the protrusions can penetrate into the soil or material, they can break hard soil blocks, crusts or compacted layers, and enhance permeability. At the same time, the protrusions also increase the friction between the roller and the ground, reducing slippage. The peeling teeth that intersect with the protrusions will quickly clean the soil on the surface of the roller, so that the efficiency of leveling the soil is guaranteed. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1 to 8 A high-efficiency saline-alkali dryland improvement device includes a body 1 and a drive platform 11 hinged to the right side of the body 1. Multiple drill rods 12 are provided on the lower side of the drive platform 11. A controller 15 is fixedly connected to the front side of the body 1. A leveling component 2 is provided on the outer side of the body 1 and the drive platform 11. The leveling component 2 includes two first hinge seats 21 fixedly connected to the upper side of the machine body 1. Two second hinge seats 22 are fixedly connected to the upper side of the drive platform 11. A first cylinder 23 is hinged together between the first hinge seats 21 and the second hinge seats 22. The telescopic end of the first cylinder 23 is hinged to the second hinge seat 22. Two third hinge seats 24 are fixedly connected to the lower side of the machine body 1. A connecting plate 25 is hinged inside the third hinge seat 24. A support frame 26 is fixedly connected to the left side of the front and rear connecting plates 25. A movable groove 27 is opened through the lower side of the interior of the support frame 26. An installation frame 28 is slidably connected inside the movable groove 27. A roller 29 is rotatably connected to the lower side of the interior of the installation frame 28.

[0023] A connecting frame 13 is provided on the upper part of the machine body 1. The connecting frame 13 is L-shaped. Flanges 14 are fixedly connected to both ends of the connecting frame 13. The flanges 14 on the lower side of the vertical part of the connecting frame 13 are bolted to the upper side of the machine body 1.

[0024] The upper sides of the connecting plate 25 and the support frame 26 are both attached to the lower side of the body 1. The shape of the movable groove 27 is adapted to the shape of the mounting frame 28. An external laser leveling sensor is provided at the lower front end of the body 1 to collect ground elevation data in real time and transmit it to the controller 15.

[0025] An adjustment component 3 is provided on the outside of the body 1. The adjustment component 3 includes a limiting plate 31 fixedly connected to the front and rear sides of the mounting frame 28. The limiting plate 31 is slidably connected to the inside of the movable groove 27, which is cross-shaped.

[0026] By adopting the above technical solution, when the machine body 1 is dragged along the saline-alkali dryland by the traction equipment, the operator first inputs the soil moisture detection data into the system through the controller 15. After the controller 15 calculates the data, it sends a telescopic command to the first cylinder 23. The cylinder body end of the first cylinder 23 is hinged to the first hinge seat 21 on the upper side of the machine body 1, and the telescopic end is hinged to the second hinge seat 22 on the upper side of the drive platform 11. When the first cylinder 23 extends, the drive platform 11 deflects forward and downward around its hinge point with the right side of the machine body 1, driving the multiple drill rods 12 below the drive platform 11 to penetrate forward and downward into the soil. When the first cylinder 23 retracts, the drive platform 11 lifts forward and upward, the drill rod 12 exits the soil, and the machine body 1 moves forward under the traction of the traction equipment. During this process, the drive platform 11 pre-crushes and loosens the soil through multiple drill rods 12 to reduce the soil hardness. The mounting frame 28 is hinged to the third hinge seat 24 on the lower side of the machine body 1 through the connecting plate 25. The upper sides of the connecting plate 25 and the support frame 26 are both in contact with the lower side of the machine body 1 to form a stable support structure. When the roller 29 rolls, it will compact or push the saline-alkali soil at high places, and the height of the roller 29 can be adjusted by the adjustment component 3. It should be noted that the controller 15 has a preset reference height value. During operation, the external laser leveling sensor collects the height difference signal between the ground surface and the reference plane in real time. When high-level saline soil is detected, the controller 15 sends an extension command to the electric push rod 32. The extension distance is proportional to the height difference signal, driving the limit plate 31 to move down along the movable groove 27, increasing the compaction intensity of the roller 29 on the soil. Conversely, the push rod is retracted to lift the soil. Since the roller 29 can automatically adjust its position according to the real-time height difference of the ground surface, it increases the compaction and pushes the saline soil in high places, and lifts the roller 29 in low places to avoid excessive compaction, realizing dynamic leveling of "cutting high and filling low", and preventing the phenomenon of "high-alkalinity depression" caused by uneven ground after deep cultivation of saline-alkali land.

[0027] like Figure 1 , Figure 4 and Figures 5 to 8 As shown, an electric push rod 32 is fixedly connected to the upper side of the inner side of the movable groove 27, and the telescopic end of the electric push rod 32 is fixedly connected to the upper side of the limiting plate 31.

[0028] Multiple fourth hinge seats 33 are fixedly connected to the left side of the body 1, and multiple fifth hinge seats 34 are fixedly connected to the upper side of the support frame 26. A second cylinder 35 is hinged together between the fourth hinge seats 33 and the fifth hinge seats 34, and the extension end of the second cylinder 35 is hinged to the fifth hinge seat 34.

[0029] By adopting the above technical solution, when the roller 29 travels to a low-lying area, the electric push rod 32 can control the installation frame 28 to rise and fall. The operator can retract the electric push rod 32 through the controller 15, the limit plate 31 moves up along the cross-shaped movable groove 27, the installation frame 28 is lifted as a whole, and the roller 29 is removed from the ground in the low-lying area, avoiding excessive compaction in the low-lying area and causing water accumulation. In the high-lying area, the electric push rod 32 extends, the installation frame 28 presses down, and the roller 29 increases the compaction and leveling force on the soil in the high-lying area, pushing the soil in the high-lying area to fill the low-lying area. Throughout the process, the controller 15 receives soil moisture detection data in real time and automatically adjusts the stroke of the first cylinder 23, the second cylinder 35 and the electric push rod 32 according to the difference in ground elevation, ensuring that the roller 29 always contacts the ground with the optimal pressure and angle. It should be noted that the cross-shaped movable groove 27 includes a longitudinal slide and a lateral fine-tuning gap. The limiting plate 31 is slidably connected in the longitudinal slide and is driven by the electric push rod 32 to adjust the main height. In order to adapt to the lateral unevenness of the salt spot accumulation area, a lateral redundancy of 10-15mm is reserved between the limiting plate 31 and the side wall of the movable groove 27. With the differential speed adjustment of the second cylinder 35, the roller 29 can achieve multi-degree-of-freedom posture compensation in the support frame 26. Due to the sliding structure of the cross-shaped movable groove 27 and the limiting plate 31, the mounting frame 28 can be finely adjusted in the support frame 26 to adapt to the extreme complex terrain such as local potholes, ruts, and salt spot accumulation areas in saline-alkali land. When a low-lying and soft area is detected, the mounting frame 28 can be quickly raised to effectively prevent secondary soil compaction and protect the soil structure of the improved area.

[0030] like Figure 2 , Figure 3 and Figures 5 to 8 As shown, the inner and outer sides of the mounting frame 28 are provided with a soil cleaning component 4, which includes a plurality of protrusions 41 fixedly connected to the outer side of the roller 29.

[0031] Multiple peeling teeth 42 are fixedly connected to the lower side of the mounting frame 28, and the multiple peeling teeth 42 and multiple protrusions 41 are arranged alternately.

[0032] By adopting the above technical solution, when the machine body 1 moves forward under the traction of the drive platform 11, the roller 29 rotates automatically around its rotation axis under the action of ground friction. The protrusion 41 rotates with the roller 29. When the protrusion 41 contacts the saline-alkali crust or hardened soil layer on the ground, due to the protrusion height and sharp edge of the protrusion 41, it will generate concentrated point impact force and shear force on the crust and break the hardened soil into small pieces. Multiple peeling teeth 42 are fixedly connected to the lower side of the mounting frame 28. The peeling teeth 42 and the protrusion 41 on the roller 29 are arranged in an alternating manner. When the roller 29 rotates, the soil attached to the groove between the protrusion 41 will be thrown out. At the same time, the peeling teeth 42 will also scrape off the soil attached to the groove between the protrusion 41. It should be noted that multiple stripping teeth 42 are fixed to the lower edge of the mounting frame 28 and are distributed in a comb-like pattern. Each stripping tooth 42 extends into the gap between two adjacent rings of protrusions 41, and the radial net gap between the tip of the stripping tooth 42 and the outer surface of the roller 29 is maintained at 3-5mm to ensure that no mechanical interference occurs while cleaning the soil. Since the protrusions 41 can penetrate deep into the soil or material, they can break up hard soil clods, crusts or compacted layers, and enhance permeability. At the same time, the protrusions 41 also increase the friction between the roller 29 and the ground, reducing slippage. The stripping teeth 42, which are intersected with the protrusions 41, will quickly clean the soil on the surface of the roller 29, thus ensuring the efficiency of leveling the soil.

[0033] like Figures 1 to 4 As shown, the inner and outer sides of the body 1 are provided with a water injection assembly 5, which includes a water storage cavity 51 opened inside the body 1.

[0034] A water injection pipe 52 is fixedly connected to the upper side of the machine body 1, and the water injection pipe 52 extends into the interior of the water storage chamber 51. Multiple delivery pipes 53 are fixedly connected to the lower side of the machine body 1, and the delivery pipes 53 are connected to the water storage chamber 51. A nozzle 54 is fixedly connected to the bottom end of the delivery pipe 53. A fixing plate 55 is fixedly connected to the lower right side of the machine body 1. A spiked rake 56 is fixedly connected to the lower side of the fixing plate 55. The spiked rake 56 is fixed below the fixing plate 55 and is located behind the machine body 1 in the direction of travel.

[0035] By adopting the above technical solution, before operation, the operator injects fresh water into the water storage chamber 51 through the water injection pipe 52 on the upper side of the machine body 1. The bottom of the water storage chamber 51 is connected to the outside through multiple delivery pipes 53, and each delivery pipe 53 is equipped with a nozzle 54 at its bottom. The nozzle 54 adopts a fan-shaped atomizing nozzle design to disperse the water flow into a uniform water curtain sprayed onto the ground. When the machine body 1 moves forward, the nozzle 54 continuously sprays under the action of water pressure in the water storage chamber 51, forming a continuous rinsing zone behind the machine body 1. The water flow seeps into the broken and turned loose soil, dissolving the soluble salts in the soil. The spiked rake 56 is set on the right side of the delivery pipe 53 and the nozzle 54. When the machine body 1 moves forward, the spiked rake 56 cuts into the soil layer, using the longitudinal grooves to break the capillary return path. The nozzle 54 adopts a fan-shaped atomizing design to evenly moisten the loosened soil layer. After the water has infiltrated for 2-3 minutes... Seconds later, the longitudinal trenches guide the subsequent saline solution to quickly infiltrate into the drainage system before the roller 29 compacts and levels it, completing the closed-loop improvement operation of "ditching and guiding - water injection and salt leaching - roller sealing". The sharp spikes are inserted into the soil, breaking the capillary sealing layer on the soil surface and accelerating the drainage of saline solution. On the other hand, they form longitudinal trenches on the soil surface. These trenches become the concentrated discharge channels for saline solution, guiding the saline solution to the pre-set drainage open ditch or underground pipe. Because the nozzle 54 adopts a fan-shaped atomizing nozzle design, it disperses the water flow into a uniform water curtain sprayed onto the ground. Compared with the direct jet method, the atomized water flow has a larger coverage area and more uniform penetration, avoiding excessive local water volume and surface runoff. At the same time, the spiked rake 56 is set on the right side of the nozzle 54, forming a "rake first, then inject" sequence operation, and guiding the saline solution to the drainage open ditch or underground pipe, preventing the saline solution from stagnating near the root layer and causing secondary salinization.

[0036] Working principle: When the machine body 1 is dragged along the saline-alkali dryland by the traction equipment, the first cylinder 23 controls the up and down rotation of the drive platform 11, driving the drill rod 12 to pre-break and loosen the soil. At the same time, the adjustable structure composed of the connecting plate 25, support frame 26, mounting frame 28 and roller 29 achieves dynamic leveling of the ground. The electric push rod 32 in the movable groove 27 controls the lifting and lowering of the mounting frame 28, and the second cylinder 35 adjusts the angle of the support frame 26, so that the roller 29 automatically adjusts according to the difference in ground level, realizing the cutting of high and filling of low, preventing secondary compaction. During this process, the protrusions 41 on the outer side of the roller 29 and the peeling teeth 42 on the lower side of the mounting frame 28 are arranged alternately. The protrusions 41 break up the salt crust and increase friction as the roller 29 rotates. The peeling teeth 42 clean the soil adhering to the surface of the roller 29. Before this, the right-side spiked rake 56 breaks the capillary sealing layer and forms a longitudinal groove, guiding the salt water to converge into the drainage ditch. Then, the fresh water sprayed by the nozzle 54 forms a continuous rinsing belt to dissolve the soil salt and prevent secondary salinization, thus completing the "breaking-rake-watering-leveling" operation sequence.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concept, should be covered within the scope of protection of the present invention.
