Description

Technical Field

[0001] This invention relates to the field of equipment technology for soil improvement of degraded grassland, and in particular to an integrated device for loosening soil and applying fertilizer to degraded grassland. Background Technology

[0002] When grasslands degrade, the soil commonly suffers from problems such as compaction, hardened surface crust, decreased organic matter content, and unbalanced nutrient distribution. Reduced soil porosity weakens water and fertilizer penetration and retention, directly hindering the natural recovery and normal growth of native vegetation. For the restoration of such degraded grasslands, loosening the soil, breaking up hardened layers, and supplementing with fertilizer are the most basic and crucial soil improvement methods. By breaking up hardened soil layers, improving soil aeration, and replenishing the soil with necessary nutrients, a suitable growth environment can be created for the recovery of plant roots. This is a widely used technical approach in grassland ecological restoration.

[0003] Currently, in the restoration of degraded grasslands, soil loosening and fertilization are mostly carried out as separate processes. Soil loosening is done first using soil loosening equipment, followed by fertilization. In some areas, backfilling is also required separately. This multi-step approach necessitates multiple trips of equipment, resulting in a long overall operation cycle, high labor and equipment costs, and repeated compaction causing additional secondary damage to the surface vegetation and shallow soil structure, thus delaying vegetation recovery. Some attempts have been made to create integrated machines that simply combine soil loosening and fertilization mechanisms, but these still have significant limitations in actual field operations, and the overall operational effectiveness and equipment durability fall short of expectations.

[0004] Regarding working depth and posture control, most existing soil loosening machines rely primarily on their own weight to control the depth of penetration, lacking active posture stabilization structures. Degraded grasslands often have uneven surfaces and varying soil hardness, making it easy for machines to fluctuate in depth during operation. In some areas, the loosening depth is insufficient to effectively break up deep compacted layers, while in others, the depth is too deep, potentially damaging the healthy root systems of native vegetation. Ultimately, the overall soil loosening quality is uneven. Furthermore, most machines have fixed traction connection structures with limited rotational flexibility, making them inconvenient to adapt to different traction equipment models. During movement and turning, issues such as jamming and deviation from the work path can easily occur, further affecting operational stability.

[0005] Regarding adaptability to complex working conditions and component protection, the soil of degraded grasslands often contains gravel of varying sizes, withered and hardened roots and stems, and solidified soil clods. Most existing soil loosening components are rigid structures, lacking effective obstacle avoidance designs. When encountering small, hard debris, the tips of the loosening teeth are continuously subjected to impact wear, leading to chipping and fatigue deformation under long-term operation, requiring frequent replacement and maintenance. When encountering larger stones, the rigid loosening teeth often cannot avoid them, causing minor issues like tooth breakage and frame deformation, or even complete machine jamming and shutdown, requiring manual obstacle removal, which not only delays the work progress but also significantly increases equipment maintenance costs. Furthermore, the soil mixing structure at the rear of most implements requires an additional power drive unit, resulting in a complex transmission structure, increased overall machine weight, a higher failure rate in field operations, and inconvenient daily maintenance.

[0006] Regarding the effectiveness of fertilization and soil covering, existing soil loosening equipment with fertilization functions generally employs a relatively simple fertilization method. Most methods involve directly spreading fertilizer on the surface of the loosened soil or applying it at a fixed depth, failing to adapt to the actual amount of soil being turned. When the amount of soil turned is small, the fertilizer exposure area is large, leading to significant volatilization and loss. When the amount of soil turned is large, the fertilizer is difficult to mix evenly with the deeper soil layers, resulting in low overall fertilizer utilization. Furthermore, most machines fail to effectively backfill and cover the soil after loosening, failing to create a stable and effective cover for the fertilized layer. Prolonged soil exposure exacerbates moisture evaporation, hindering soil moisture retention and ultimately significantly reducing the actual soil improvement effect.

[0007] Therefore, developing an integrated soil loosening and fertilization device that has stable operating posture, adaptive obstacle avoidance and protection capabilities, and can perform fertilization and layered soil covering in conjunction with each other is of great practical significance for improving the efficiency of degraded grassland restoration and the quality of soil improvement. Summary of the Invention

[0008] The purpose of this invention is to provide an integrated device for loosening soil and applying fertilizer to degraded grassland, so as to solve the technical problems existing in the prior art.

[0009] By adopting the above technical solution, the present invention has the following beneficial effects: The present invention provides an integrated device for loosening soil and applying fertilizer to degraded grassland, including a horizontally arranged traction beam, a traction mounting frame located at the middle of one side of the traction beam, a traction rotating column rotatably arranged in conjunction with the traction mounting frame, a traction ring being provided on the traction rotating column, and two sets of traction mounting columns symmetrically arranged at both ends of the other side of the traction beam. It also includes: an adjusting soil loosening mechanism, a linkage material guiding and fertilizing mechanism, and a stabilizing moving mechanism.

[0010] As a further aspect of the present invention: the adjusting soil breaking and loosening mechanism includes an adjusting mounting plate, and the outer ends of the two sets of traction mounting columns are each provided with an adjusting mounting frame. The adjusting mounting plate is located between the two adjusting mounting frames, and an adjusting shaft is provided on the adjusting mounting plate between the two adjusting mounting frames. The ends of the adjusting mounting frames that cooperate with the adjusting shaft are each provided with a synchronous adjusting drive component.

[0011] As a further aspect of the present invention: a plurality of inclined soil-breaking teeth are provided at equal intervals on one end of the adjustment mounting plate, and the outer ends of the inclined soil-breaking teeth are provided with clearance warping protrusions.

[0012] As a further aspect of the present invention: guide strips are horizontally arranged at equal intervals on the adjusting mounting plate between the adjusting shaft and the inclined soil breaking teeth.

[0013] As a further embodiment of the present invention: a plurality of limiting rotating sleeves are provided at equal intervals on the other end of the adjusting mounting plate, and a limiting rotating shaft is provided for each limiting rotating sleeve. The limiting rotating shaft and the limiting rotating sleeve are both inclined, and a passive spiral stirring plate is provided at the outer end of the limiting rotating shaft.

[0014] As a further embodiment of the present invention: the ends of the adjusting mounting plate are partially covered by guide tubes in conjunction with the passive spiral mixing plate.

[0015] As a further aspect of the present invention: the linkage material guiding and fertilizing mechanism includes an arc-shaped material guiding plate set above the adjusting mounting plate, a number of corrugated protrusions with V-shaped cross sections are evenly spaced on the arc-shaped material guiding plate, and an inclined shovel surface is provided at the end of the corrugated protrusions near the inclined soil breaking teeth. An arc-shaped guide pipe is provided on the inner side of the corrugated protrusions, and a number of fertilizing holes are evenly spaced on the arc-shaped guide pipe.

[0016] As a further embodiment of the present invention: the two ends of the arc-shaped guide plate are symmetrically provided with reset shafts, and the traction mounting column is provided with bearing mounting grooves in cooperation with the reset shafts at both ends.

[0017] As a further embodiment of the present invention: the adjusting mounting plate between the adjusting shaft and the passive spiral stirring plate is symmetrically provided with limit adjusting plates on both the front and rear sides, and the upper end of each limit adjusting plate is provided with an arc-shaped gasket.

[0018] As a further aspect of the present invention: a connecting guide tube is attached to the lower side of the arc-shaped guide plate, and the connecting guide tube is connected to each arc-shaped guide tube in sequence through a connecting guide hole, and flexible guide tubes are provided at both ends of the connecting guide tube.

[0019] As a further aspect of the present invention: the traction mounting column is provided with a liquid storage chamber inside, and an external conduit extending out of the traction mounting column is provided at the upper end of the liquid storage chamber, with the outer end of the flexible conduit communicating with the bottom of the liquid storage chamber.

[0020] As a further embodiment of the present invention: the stabilizing moving mechanism includes symmetrically arranged swing drive shafts, which are respectively arranged on the opposite side of the traction mounting columns. Each swing drive shaft is provided with a swing mounting column, and a plurality of stabilizing guide plates are provided near the outer end of the swing mounting column. The stabilizing guide plates are arranged in parallel with each other.

[0021] Compared with the prior art, the beneficial effects of the present invention are: The device exhibits stable operation and consistent soil loosening depth. It features a stable movement mechanism; during initial operation, a swing drive shaft propels the stabilizing guide plate into the soil and maintains its set posture. This effectively prevents excessive sinking or lateral shifting of the device on degraded grasslands and undulating surfaces, ensuring stable operating depth throughout the process. Combined with a rotatable traction connection structure, the traction installation and movement process are smoother, making it suitable for grassland restoration operations on complex terrains.

[0022] It possesses graded obstacle avoidance capabilities, exhibiting strong operational adaptability and component protection. The adjustable mounting plate can be angled via synchronously adjusted drive components, altering the entry angle of the inclined soil-breaking teeth to adapt to grassland soils with varying degrees of degradation and hardness, meeting diverse soil loosening requirements. The ends of the inclined soil-breaking teeth feature clearance warping protrusions; when encountering small, hard obstacles, they deform to allow for clearance, being discharged backward along the guide strip with the soil. When encountering heavy, hard objects, the adjustable mounting plate passively flips, lifting the arc-shaped guide plate to form a continuous guide slope, raising large stones to the surface. This facilitates soil debris removal and prevents impact damage to the rear passive spiral mixing plate, extending the device's lifespan. The passive spiral mixing plate rotates based on soil resistance, requiring no additional power source; its simple structure and low energy consumption allow for simultaneous soil mixing after fertilization.

[0023] The integrated fertilization and soil covering operation ensures high fertilizer utilization and restoration quality. The device integrates a liquid fertilizer delivery system, with the storage chamber integrated inside the traction mounting column. Liquid fertilizer is distributed to the guide pipes within the arc-shaped guide plate via flexible conduits and connecting pipes, and then evenly applied to the soil through fertilization holes. The overall pipeline layout is compact. During operation, it naturally forms a layered operation state according to the amount of soil turned: when the amount of soil turned is small, the soil passes under the arc-shaped guide plate, and after fertilization, it is mixed, collected, and backfilled; when the amount of soil turned is large, excess soil is quickly guided through the corrugated protrusions from above the arc-shaped guide plate, eventually falling back to cover the lower layer of fertilized and mixed soil, forming a soil covering effect. This effectively reduces fertilizer volatilization and loss, improving the soil restoration effect of degraded grassland.

[0024] The device integrates multiple processes into one unit, resulting in high operational efficiency. It combines functions such as traction connection, posture stabilization, soil breaking and loosening, obstacle avoidance and protection, fertilization and mixing, and soil covering and backfilling into one unit. All processes can be completed in one pass during degraded grassland restoration operations, greatly improving operational efficiency and reducing secondary damage to grassland caused by repeated compaction. It is applicable to a wide range of scenarios. Attached Figure Description

Detailed Implementation

[0037] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0038] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0039] Example 1: Basic structure and posture stability operation of the integrated soil loosening and fertilization device for degraded grassland Please see Figures 1-3 This embodiment mainly explains the basic support structure of the integrated device, as well as the connection preparation and depth attitude stabilization control process in the early stage of operation.

[0040] This device includes a horizontally arranged traction beam 2, a traction mounting frame 3 is arranged at the middle position on one side of the traction beam 2, a traction rotating column 4 is rotatably arranged in conjunction with the traction mounting frame 3, and a traction ring 5 is arranged on the traction rotating column 4; two sets of traction mounting columns 1 are symmetrically arranged at both ends on the other side of the traction beam 2.

[0041] Furthermore, the device includes a stabilizing moving mechanism, which includes symmetrically arranged swing drive shafts 9. The swing drive shafts 9 are respectively arranged on opposite sides of the traction mounting columns 1. Each swing drive shaft 9 is provided with a swing mounting column 11. Several stabilizing guide plates 12 are arranged near the outer end of the swing mounting column 11. The stabilizing guide plates 12 are arranged in parallel with each other.

[0042] During the preparation and connection phase, the device is connected to the external traction equipment through the traction ring 5 set on the traction beam 2. The traction rotating column 4 and the traction mounting frame 3, which are rotated together with the traction mounting frame 3, make the traction installation and operation process smoother.

[0043] During the initial attitude and depth adjustment phase, the stabilizing mechanism intervenes. The swing drive shaft 9 drives the swing mounting column 11 and its stabilizing guide plate 12 to move. After the stabilizing guide plate 12 is inserted into the ground at a certain angle and depth in the initial stage of operation, it returns to a horizontal state or maintains a certain angle, so that the device always moves at the preset depth during the movement process, preventing the device from sinking or deviating excessively on degraded grassland undulating surfaces.

[0044] Example 2: Adjustable soil breaking and loosening operation with adaptive obstacle avoidance and protection functions Please see Figures 1-6 Based on Example 1, this example mainly clarifies the structure of the soil breaking and loosening mechanism, as well as the adaptive soil breaking and obstacle avoidance process when facing complex degraded grassland.

[0045] The adjusting soil breaking and loosening mechanism includes an adjusting mounting plate 10. The outer ends of the two sets of traction mounting columns 1 are each provided with an adjusting mounting frame 16. The adjusting mounting plate 10 is located between the two adjusting mounting frames 16, and an adjusting rotating shaft 21 is provided on the adjusting mounting plate 10 between the two adjusting mounting frames 16. The ends of the adjusting mounting frames 16 that cooperate with the adjusting rotating shaft 21 are each provided with a synchronous adjusting drive component 17.

[0046] One end of the adjusting mounting plate 10 is provided with a plurality of inclined soil-breaking teeth 19 at equal intervals, and the outer end of each inclined soil-breaking tooth 19 is provided with a clearance warping protrusion 25; the adjusting mounting plate 10 between the adjusting shaft 21 and the inclined soil-breaking teeth 19 is provided with guide strips 24 at equal intervals horizontally. The other end of the adjusting mounting plate 10 is provided with a plurality of limiting rotating sleeves 26 at equal intervals, and each limiting rotating sleeve 26 is provided with a limiting rotating shaft 27. Both the limiting rotating shaft 27 and the limiting rotating sleeve 26 are inclined, and the outer end of the limiting rotating shaft 27 is provided with a passive spiral mixing plate 14; the end of the adjusting mounting plate 10 is partially covered with a guide cylinder 13 in conjunction with the passive spiral mixing plate 14.

[0047] In addition, limit adjustment plates 15 are symmetrically arranged on the front and rear sides of the adjustment mounting plate 10 between the adjustment shaft 21 and the passive spiral stirring plate 14, and arc-shaped gaskets 18 are provided on the upper end of each limit adjustment plate 15.

[0048] The synchronous adjustment drive 17 is activated, and the angle of the adjustment mounting plate 10 and its upper inclined soil breaking teeth 19 is changed by adjusting the rotating shaft 21 to adapt to the different conditions and needs of degraded grassland, so as to carry out soil loosening operations at different angles.

[0049] As it moves forward, the oblique soil-breaking tooth 19 pierces the grass. The clearance warping protrusion 25 provided at the outer end of the oblique soil-breaking tooth 19 can deform and make way when it encounters a hard object, so that the oblique soil-breaking tooth 19 moves downward to avoid the hard object.

[0050] If a small, hard object is encountered, the small, hard object will be pried up by the displacement of the movement, and will move backward along the adjusting mounting plate 10 and the guide strips 24 that are horizontally arranged at equal intervals on it.

[0051] If a heavy, hard object is encountered, the heavy, hard object will cause the adjusting mounting plate 10 to passively rotate around the adjusting shaft 21 until the limiting adjusting plates 15 and the arc-shaped pads 18 at the upper end of the adjusting mounting plate 10, which are symmetrically arranged on the front and rear sides, come into contact with the arc-shaped guide plate 7 above. This causes the arc-shaped guide plate 7 to rotate around the reset shafts 8 at both ends until the corrugated protrusions 29 on the arc-shaped guide plate 7 and the inclined shovel surface 28 near the inclined soil breaking tooth 19 are in contact with the adjusting mounting plate 10, forming a complete inclined surface.

[0052] The complete ramp pries the heavy, hard object and guides it over the upper side of the curved guide plate 7, eventually rolling it onto the ground surface. Lifting the heavy, hard object above the soil facilitates the removal of debris and protects the passive spiral mixing plate 14 at the rear end from deformation due to impact from the heavy object.

[0053] Example 3: Coordinated application of fertilizer and covering with soil based on different tillage amounts Please see Figures 1-10 Based on Examples 1 and 2, this example mainly clarifies the fluid pipeline layout of the linkage material guiding and fertilizing mechanism, as well as the collaborative operation mode of fertilization, mixing and layered soil covering when facing different soil turning volumes.

[0054] The linkage feeding and fertilization mechanism includes an arc-shaped feeding plate 7 set above the adjusting mounting plate 10. The arc-shaped feeding plate 7 has a reset rotating shaft 8 symmetrically arranged at both ends. The traction mounting column 1 is equipped with a bearing mounting groove 23 in cooperation with the reset rotating shaft 8 at both ends.

[0055] The arc-shaped guide plate 7 has several corrugated protrusions 29 with V-shaped cross sections at equal intervals. Each corrugated protrusion 29 has an inclined shovel surface 28 at one end near the inclined soil breaking tooth 19. An arc-shaped guide pipe 31 is provided on the inner side of the corrugated protrusion 29. Several fertilizer holes 32 are provided on the arc-shaped guide pipe 31 at equal intervals.

[0056] The traction mounting column 1 has a liquid storage chamber 22 inside, and an external conduit 6 extending out of the traction mounting column 1 is provided at the upper end of the liquid storage chamber 22. A connecting guide pipe 30 is attached to the lower side of the arc-shaped guide plate 7. The connecting guide pipe 30 is connected to each arc-shaped guide pipe 31 in sequence through the connecting guide hole 33. Flexible conduits 20 are provided at both ends of the connecting guide pipe 30, and the outer end of the flexible conduit 20 is connected to the bottom of the liquid storage chamber 22.

[0057] An externally installed pump mechanism continuously delivers liquid fertilizer and other materials to the storage chamber 22 via an external conduit 6 for later use. During operation, after the liquid fertilizer is pumped into the storage chamber 22, it flows into the flexible conduit 20, enters the connecting guide pipe 30, and is then distributed sequentially to each arc-shaped guide pipe 31, and finally discharged through several fertilizer application holes 32.

[0058] During normal operation, the arc-shaped guide plate 7 is on top, and the adjusting mounting plate 10 is on the bottom. Depending on the amount of soil turned over, two modes are presented: When the amount of soil being turned over is small, some soil is conveyed backward through the inclined soil-breaking teeth 19 and the guide strips 24, and passes under the arc-shaped guide plate 7. The upper arc-shaped guide plate 7 only performs fertilization, discharging fertilizer into the turned soil below. The soil continues to move backward to the other end of the adjusting mounting plate 10, where the inclined limiting rotating sleeve 26 and limiting rotating shaft 27 are passively rotated, driving the passive spiral mixing plate 14 to rotate, thoroughly mixing the fertilized soil, and finally being collected and backfilled by the guide cylinder 13.

[0059] When a large amount of soil is turned over, besides some soil passing underneath and receiving fertilizer and mixing, some excess soil will rise above the curved guide plate 7. At this time, the corrugated protrusions 29 on the curved guide plate 7 allow small soil volumes to clump together and quickly pass over the curved guide plate 7. The small soil volumes passing over the curved guide plate 7 are not densely clumped, so they do not affect the soil loosening effect. Moreover, this part of the soil that quickly passes over eventually falls back down, precisely covering the soil below that has been fertilized and mixed by the passive spiral mixing plate 14, thereby improving the quality of soil loosening and effectively reducing losses such as fertilizer volatilization.
