Description

Technical Field

[0001] This invention relates to the field of soil loosening machine technology, and in particular to an adjustable intelligent soil loosening machine for agricultural planting. Background Technology

[0002] Fruit tree planting is a crucial step in its life cycle, directly determining its survival rate and long-term growth. Current conventional planting preparations generally involve digging planting holes of limited size and directly applying base fertilizer, a method with significant limitations.

[0003] Conventional planting hole sizes (usually the same size as or slightly larger than the root ball) can only accommodate the initial root system, failing to provide sufficient optimized space for long-term, healthy root expansion. After penetrating the improved soil in the planting hole, fruit tree roots quickly come into contact with the surrounding unimproved, potentially compacted native soil, creating a "root cage" effect that hinders further downward and outward extension, resulting in small canopies, poor resilience, and a higher risk of toppling in adulthood. Secondly, failure to effectively loosen the hardened bottom of the hole can easily lead to waterlogging and root rot after watering. Furthermore, concentrating base fertilizer near the roots greatly increases the risk of "root burn," threatening the survival of the seedlings.

[0004] Therefore, there is an urgent need in this field for a method of loosening the soil and applying fertilizer before planting fruit trees that can overcome the above-mentioned defects. This method should be able to systematically create a deep and wide optimized root zone, ensure uniform and lasting fertility without the risk of root burn, and provide standardized operating procedures to significantly improve the survival rate of fruit trees and lay a solid foundation for their lifelong healthy growth. Summary of the Invention

[0005] To overcome the shortcomings of existing planting holes, which fail to effectively loosen the hard bottom of the hole and concentrate the base fertilizer near the root system, this invention provides an adjustable intelligent soil loosening machine for agricultural planting.

[0006] The technical solution of this invention is: an adjustable intelligent soil loosening machine for agricultural planting, comprising a columnar mounting frame; the columnar mounting frame is composed of two arc-shaped mounting frames, the connecting ends of the two arc-shaped mounting frames are connected by a rotating shaft, one arc-shaped mounting frame is rotatably connected to a fixing bolt, and the other arc-shaped mounting frame is provided with a fixing groove that cooperates with the fixing bolt for fixing; it also includes a lead screw, an electric slider, a mounting plate, an arc-shaped guide rail, an arc-shaped slider, and a scribing blade; several lead screws are fixedly connected to each arc-shaped mounting frame, and an electric slider is connected to each lead screw; all electric sliders on the same arc-shaped mounting frame are fixedly connected to a mounting plate and an arc-shaped guide rail, and an arc-shaped slider is slidably connected to each arc-shaped guide rail; when all arc-shaped guide rails are in contact with each other, they form a ring guide rail; the mounting plate is provided with a driving mechanism for driving the arc-shaped sliders to slide along the arc-shaped guide rails, and several scribing blades are provided on each arc-shaped slider.

[0007] Preferably, the drive mechanism consists of a torque motor, a gear, and an arc rack. Several torque motors are provided on each mounting plate, and a gear is fixed to the rotating shaft of each torque motor. An arc rack is fixed to each arc slider, and the arc rack meshes with the gear.

[0008] Preferably, it also includes fixing rods; each arc-shaped bracket has several fixing rods detachably connected to its bottom.

[0009] Preferably, it also includes an adjustment assembly for adjusting the installation angle of the scribing blade; each scribing blade is provided with an adjustment assembly at the connection between it and the corresponding arc-shaped slider. The adjustment assembly consists of a fixed base, an electric push rod, wedge block I, wedge block II, and a rotating rod; the fixed base is fixedly connected to the arc-shaped slider; the fixed base is rotatably connected to the electric push rod; the telescopic part of the electric push rod is rotatably connected to wedge block I; wedge block I is slidably connected to wedge block II, and wedge block I and wedge block II are engaged by a slot; a rotating rod is connected to wedge block II, the rotating rod is rotatably connected to the arc-shaped slider, and the rotating rod is fixedly connected to the scribing blade.

[0010] Preferably, it also includes an infusion tube and nozzles. Each rotating rod is equipped with an infusion tube, and each scalpel is vertically equipped with several nozzles, all of which are connected to the corresponding infusion tube.

[0011] Preferably, all nozzles are positioned so that the spray direction is upward.

[0012] Preferably, the device also includes a miniature push rod, a support block, a torsion spring, and a cover plate. Each slicing blade is provided with a miniature push rod and two torsion springs. The rotating part of each torsion spring is connected to a cover plate. When all the cover plates on the same slicing blade are closed, they together form a closed space for protecting the nozzle. The telescopic part of the miniature push rod is connected to a support block, and the support block is slidably connected to the corresponding cover plate.

[0013] Preferably, the cover plate also includes a cutter, with several horizontally arranged cutters on each cover plate.

[0014] Preferably, both ends of the curved slider are rounded chamfers.

[0015] Preferably, the fixing rods are flat in shape and all fixing rods are arranged radially toward the axis of the column mounting bracket.

[0016] The beneficial effects of this invention: The core advantage of this intelligent soil loosening machine lies in achieving efficient, circular, adjustable, and integrated soil loosening and fertilization operations. Its basic functions are achieved through the synergistic action of a columnar mounting frame, an arc-shaped guide rail, an arc-shaped slider, and a cutting blade: This invention can precisely loosen the soil around the plant roots in a circular motion. It integrates an infusion pipe and a nozzle, allowing liquid fertilizer to be sprayed simultaneously with soil loosening, ensuring uniform mixing of the fertilizer and soil, effectively avoiding the "root burn" problem caused by concentrated fertilizer application in traditional hole-applying methods. The adjustment component can dynamically change the installation angle of the cutting blade, allowing it to swing while revolving, significantly expanding the loosening range per pass and improving the thoroughness and uniformity of the operation.

[0017] The columnar mounting frame consists of two arc-shaped mounting brackets connected by a pivot and fixing bolts to form an openable structure, allowing it to be easily fitted onto the roots of fruit trees or other plants for operation. This perfectly solves the problem of fixed equipment being unable to operate in planted areas. Furthermore, by removing or installing the fixing rods at the bottom, this invention can adapt to different power sources: it can rely on the reaction force provided by large agricultural machinery, or, during manual or small-scale machinery operation, the fixing rods, which penetrate the soil, can resist the significant resistance during the cutting operation. In particular, when the fixing rods are designed to be flat and arranged radially, they provide sufficient support while being easier to penetrate the soil.

[0018] A miniature pusher actuates the support block, which in turn controls the opening and closing of the cover plate connected by a torsion spring. The cover plate closes when the cutter penetrates and withdraws from the soil, creating a sealed protective space for the spray nozzle; it only opens when fertilization and soil loosening are needed. Simultaneously, the cutter mounted on the cover plate effectively cuts horizontal and vertical residual tree roots in the soil when extended, clearing obstacles for crop root growth. Furthermore, details such as the rounded chamfers at both ends of the curved slider effectively reduce movement resistance, making operation smoother. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 An adjustable intelligent soil loosening machine for agricultural planting, such as Figures 1-11 As shown, it includes a columnar mounting bracket 1; the columnar mounting bracket 1 is composed of two arc-shaped mounting brackets 11, the connecting ends of the two arc-shaped mounting brackets 11 are connected by a rotating shaft, a fixing bolt 12 is rotatably connected on one of the arc-shaped mounting brackets 11, and a fixing groove 13 is provided on the other arc-shaped mounting bracket 11 to cooperate with the fixing bolt 12 for fixing. It also includes lead screws 21, electric sliders 22, mounting plates 23, arc-shaped guide rails 24, arc-shaped sliders 34, and scribing blades 46; several lead screws 21 are fixedly connected to each arc-shaped mounting frame 11, and an electric slider 22 is connected to each lead screw 21. All electric sliders 22 on the same arc-shaped mounting frame 11 are fixedly connected to a mounting plate 23 and an arc-shaped guide rail 24. An arc-shaped slider 34 is slidably connected to each arc-shaped guide rail 24. When all arc-shaped guide rails 24 are in contact with each other, they form a ring-shaped guide rail; the mounting plate 23 is provided with a driving mechanism for driving the arc-shaped sliders 34 to slide along the arc-shaped guide rails 24, and several scribing blades 46 are provided on each arc-shaped slider 34.

[0023] The drive mechanism consists of a torque motor 31, a gear 32 and an arc rack 33. Each mounting plate 23 is equipped with three torque motors 31. The rotating shaft of each torque motor 31 is fixedly connected to a gear 32. Each arc slider 34 is fixedly connected to an arc rack 33, which meshes with the gear 32.

[0024] It also includes fixing rods 14; each arc-shaped bracket has several fixing rods 14 detachably connected to its bottom.

[0025] It also includes an adjustment component; each scribing blade 46 is provided with an adjustment component at the connection between itself and the corresponding arc-shaped slider 34. The adjustment component consists of a fixed base 41, an electric push rod 42, a wedge block I 43, a wedge block II 44, and a rotating rod 45. The fixed base 41 is bolted to the arc-shaped slider 34. The fixed base 41 is rotatably connected to the electric push rod 42. The telescopic part of the electric push rod 42 is rotatably connected to the wedge block I 43. The wedge block I 43 is slidably connected to the wedge block II 44, and the wedge block I 43 and the wedge block II 44 are fastened by a slot to prevent the wedge block I 43 and the wedge block II 44 from disconnecting. The rotating rod 45 is connected to the wedge block II 44, and the rotating rod 45 is rotatably connected to the arc-shaped slider 34. The rotating rod 45 is fixedly connected to the scribing blade 46.

[0026] It also includes an infusion tube 51 and a nozzle 52. Each rotating rod 45 is equipped with an infusion tube 51, and each scalpel 46 is vertically equipped with nine nozzles 52. All nozzles 52 are connected to the corresponding infusion tube 51.

[0027] All nozzles 52 are set to spray upwards to prevent soil from being squeezed into the nozzles 52 and causing blockage when the cutter 46 pierces the soil, thus affecting the operation of the nozzles 52.

[0028] It also includes a miniature push rod 61, a support block 62, a torsion spring 63, and a cover plate 64. Each slicing blade 46 is provided with a miniature push rod 61 and two torsion springs 63. The rotating part of each torsion spring 63 is connected to a cover plate 64. When all the cover plates 64 on the same slicing blade 46 are closed, they together form a closed space for protecting the nozzle 52. The telescopic part of the miniature push rod 61 is connected to a support block 62, and the support block 62 is slidably connected to the corresponding cover plate 64.

[0029] It also includes a cutter 65, with several horizontally arranged cutters 65 on each cover plate 64.

[0030] Both ends of the curved slider 34 are rounded chamfered.

[0031] When the column mounting frame 1 is installed on other agricultural machinery, the fixing rod 14 is removed from the bottom of the arc mounting frame 11. The resistance of the scratching blade 46 moving in the soil can be resisted by the agricultural machinery itself. When manual operation is required or the corresponding agricultural machinery is small, the fixing rod 14 is installed at the bottom of the arc mounting frame 11. At this time, before using the scratching blade 46 to loosen the soil, the fixing rod 14 is first inserted into the soil at the bottom of the planting hole. The multiple fixing rods 14 inserted into the soil resist the resistance of the scratching blade 46 moving in the soil.

[0032] The working principle of the slicing blade 46 for loosening soil is as follows: First, it is moved to the bottom of the column mounting frame 1 and the bottom of the planting hole. Then, the infusion pipe 51 is connected to the external pump. Then, the electric slider 22 is driven to work. The motor inside the electric slider 22 works, which in turn works with the screw 21 fixed to the arc mounting frame 11 to move up and down. Then, the arc slider 34 is driven to move down through the mounting plate 23 and the arc guide rail 24, which in turn drives the slicing blade 46 to penetrate the soil at the bottom of the planting hole. As the slicing blade 46 gradually penetrates the soil, the torque motor 31 drives the corresponding gear 32 to rotate, which drives the arc rack 33 that meshes with it to revolve around the axis of the column mounting frame 1. Then, the arc rack 33 drives the corresponding arc slider 34 to move along the ring guide rail formed by all the arc guide rails 24, which drives the slicing blade 46 to make a circular motion around the axis of the column mounting frame 1. Thus, the slicing blade 46, which gradually penetrates the soil and makes a circular motion, achieves the function of loosening soil. After the cutting blade 46 is fully inserted into the soil, the arc-shaped slider 34 continues to rotate. At this time, the external pump is activated to deliver liquid fertilizer into the infusion pipe 51. After being delivered through the infusion pipe 51, the liquid fertilizer is sprayed out from the nozzle 52, thus allowing the liquid fertilizer to enter the soil. Combined with the loosening action of the cutting blade 46, the liquid fertilizer is mixed with the soil to solve the technical problem of "root burn" caused by concentrated application of base fertilizer near the root system.

[0033] When the scratching blade 46 only rotates in a circle, the soil loosening effect is limited. Therefore, by adding an adjustment component at the connection between each scratching blade 46 and the corresponding arc-shaped slider 34, the installation angle of the scratching blade 46 can be adjusted by the adjustment component, so that the installation angle of the scratching blade 46 can be changed while the scratching blade 46 is rotating in a circle, thereby expanding the soil loosening range of the scratching blade 46.

[0034] The working principle of the adjustment component is as follows: Figure 5 As shown, during the process of the cutting blade 46 penetrating the soil, the extension part of the electric push rod 42 is extended, which in turn drives the wedge block I 43 to move forward, thereby squeezing the wedge block II 44 and causing the wedge block II 44 to move towards the axis of the column mounting bracket 1. This, in turn, drives the rotating rod 45 to rotate, thereby adjusting the angle of the cutting blade 46. At this time, the states of the wedge block I 43 and the wedge block II 44 are as follows: Figure 6 As shown, the state of the scribing blade 46 at this time is as follows: Figure 11 As shown, the angle of the cutting blade 46 is controlled by controlling the extension of the telescopic part of the electric push rod 42. It should be noted that in order to facilitate the cutting blade 46 to penetrate the soil, the cutting blade 46 is initially in a vertical state. Before the cutting blade 46 is pulled out of the soil, the telescopic part of the electric push rod 42 needs to be retracted to reset the wedge block I 43. Then, through the groove between the wedge block I 43 and the wedge block II 44, the connection between the wedge block I 43 and the wedge block II 44 is prevented from being disconnected, thereby resetting the wedge block II 44 and driving the cutting blade 46 to reset to a vertical state for easy removal. It should be noted that the telescopic part of the electric push rod 42 can also be controlled to continue to retract, so that the wedge block I 43 drives the wedge block II 44 away from the axis of the column mounting frame 1, thereby causing the slicing blade 46 to tilt toward the axis of the column mounting frame 1 to treat the soil in the middle of the planting hole.

[0035] As is common knowledge in mechanical motion, lubrication is necessary between wedge block I 43 and wedge block II 44 to reduce resistance, and the fixed seat 41 is rotatably connected to the electric push rod 42; the telescopic part of the electric push rod 42 is rotatably connected to wedge block I 43, and the rotating rod 45 is rotatably connected to the arc-shaped slider 34, providing a degree of freedom for the rotating rod 45 to drive the scriber 46 to move.

[0036] When the fruit trees have been planted in the planting holes and need fertilization, the fixing bolt 12 is detached from the fixing groove 13, thereby releasing the limiting position of the two arc-shaped mounting brackets 11. The column mounting bracket 1 is then opened via the pivot between the two arc-shaped mounting brackets 11, and the state at this time is as follows. Figure 2 As shown, the column mounting bracket 1 is then placed on the outside of the plant and closed. The fixing bolt 12 is then fastened back into the fixing groove 13 to achieve the closed limit of the two arc mounting brackets 11 and to make the arc guide rail 24 re-form a ring guide rail. Then the above-mentioned loosening and fertilizing operations are repeated.

[0037] By using the nozzle 52 with the spray direction facing upward, it is possible to avoid soil being squeezed into the nozzle 52 and causing blockage when the cutter 46 pierces the soil, which would affect the fertilization work of the nozzle 52. However, when the cutter 46 is pulled out of the soil, the soil is easy to enter the upward-moving nozzle 52, which means that before the next fertilization, the soil blockage at the nozzle 52 needs to be checked and cleaned, which affects the work efficiency. Therefore, a miniature push rod 61, a support block 62, a torsion spring 63 and a cover plate 64 are added to each cutter 46. The working principle of the cover plate 64 is as follows: Before the cutting blade 46 penetrates the soil, the cover plate 64 is formed under the action of the torsion spring 63. Figure 7 In the closed state shown, the nozzle 52 is protected by the cover plate 64. When the arc-shaped slider 34 drives the scrubbing blade 46 to make a circular motion, the telescopic part of the micro push rod 61 is controlled to retract, which drives the support block 62 to approach the torsion spring 63. In turn, the support block 62 opens the closed cover plate 64. At this time, the torsion spring 63 deforms and stores force, causing the cover plate 64 to change Figure 8 In the open state shown, the open cover plate 64 enhances the soil-loosening effect of the scratching blade 46 and stops obstructing the nozzle 52, allowing the nozzle 52 to operate normally. After the scratching blade 46 completes its work, the torque motor 31 drives the arc-shaped slider 34 to move back to the corresponding arc-shaped guide rail 24 through the gear 32 and the arc-shaped rack 33. At this time, the telescopic part of the micro push rod 61 extends and resets, causing the cover plate 64 to lose its opening force. Under the reset force of the torsion spring 63, the cover plate 64 resets, thereby covering the nozzle 52 again for protection, preventing soil from clogging the nozzle 52, and reducing the resistance to pulling out the scratching blade 46.

[0038] When residual tree roots are present in the soil, the slicing blade 46 can only cut horizontally extending roots and cannot handle vertically extending roots. Therefore, a cutting blade 65 is added to the cover plate 64. When the cover plate 64 is opened, the cutting blade 65 also unfolds, allowing the vertically extending roots to be processed. When the slicing blade 46 is pulled out, the cover plate 64 becomes... Figure 7 In the closed state shown, the cutter 65 also retracts behind the slicing blade 46 to reduce the resistance brought by the cutter 65 and make it easier to pull out the slicing blade 46.

[0039] Example 2 Based on Example 1, such as Figures 1-2 and Figures 10-11 As shown, the fixing rod 14 is flat in shape, and all fixing rods 14 are arranged radially toward the axis of the column mounting bracket 1.

[0040] When multiple fixing rods 14 resist the resistance of the cutting blade 46 moving in the soil, the cross-sectional area of ​​the fixing rod 14 in the direction of resistance is proportional to the supporting force provided by the fixing rod 14. That is, the larger the volume of the fixing rod 14, the greater the supporting force it provides. However, fixing rods 14 with too large a volume will be more difficult to penetrate into the soil. Therefore, the fixing rods 14 are set to be flat as a whole, and all fixing rods 14 are arranged radially toward the axis of the column mounting frame 1. While keeping the supporting force provided by the fixing rods 14 unchanged, the cross-sectional area on the horizontal plane is reduced, making it easier for the fixing rods 14 to penetrate into the soil.

[0041] 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. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
