A landscape garden soil loosening and fertilizing integrated machine

Abstract

This invention discloses an integrated soil loosening and fertilizing machine for landscape gardening, relating to the technical field of integrated soil loosening and fertilizing machines. It includes a frame, a push handle, and wheels. The push handle is fixed to the rear end of the frame, and the wheels are rotatably connected to the front end of the push handle. It also includes a hopper, a disc, and a second component. Through the coordinated design of the second and third components, the generation of fine powder can be effectively reduced, breaking the vicious cycle of "broken fertilizer—sticking to the wall—re-clogging." Existing rotating mixing structures continuously disturb the flow, easily generating a large amount of fine fertilizer powder. This fine powder is highly adhesive and easily adheres to the hopper wall, further exacerbating material accumulation, agglomeration, and secondary clogging. This design eliminates forced mixing and crushing actions, using vertical piercing and horizontal loosening to break up bridging and rat holes throughout the process. It does not grind and generate fine powder materials, reducing fertilizer sticking to the wall and solidifying at the source, breaking the vicious cycle problem caused by traditional mixing structures, making the hopper discharge cleaner and smoother, and preventing material residue accumulation during long-term operation.

Description

Technical Field

[0001] This invention relates to the field of integrated soil loosening and fertilization machines, specifically to an integrated soil loosening and fertilization machine for landscape gardening. Background Technology

[0002] Landscape plants are prone to problems such as soil compaction, nutrient loss, and decreased soil fertility during long-term growth. To ensure the healthy growth of landscape vegetation and maintain a good greening effect, it is necessary to regularly loosen the soil and fertilize the green areas. Hand-push fertilization equipment is widely used in the precision fertilization operations of landscape gardens due to its advantages of small size, convenient operation, and suitability for small plots and complex terrain.

[0003] Most fertilizer application equipment on the market currently adopts an inverted cone-shaped silo structure that is wider at the top and narrower at the bottom. While this structure facilitates material aggregation and feeding, it is prone to causing discharge blockages and uneven fertilization during the actual conveying of granular fertilizers, slow-release fertilizers, and garden organic fertilizers containing fine powder. Specifically, fertilizer granules are susceptible to two typical blockage phenomena inside the silo: arching and rat holes, due to the combined effects of granule cohesion, material weight pressure, and silo wall friction. Arching occurs when the fertilizer layer above the discharge port solidifies into an arched bridging structure, preventing the upper fertilizer from falling and causing complete blockage. Rat holes are a hidden blockage problem that is very common in inverted cone-shaped silos. In this case, only a narrow vertical flow channel forms in the central area of ​​the silo, and the fertilizer around the channel remains stationary and cannot slide to replenish, resulting in intermittent fertilizer feeding and highly unstable flow, which seriously affects the uniformity of fertilization and the continuity of operation.

[0004] To address the issues of material blockage and uneven fertilization caused by silo arching and rodent burrows, existing technologies generally employ continuously rotating, motor-driven agitator components. These components use a constantly rotating agitator to agitate the fertilizer within the silo, attempting to break up blockages and ensure normal material flow. However, this traditional agitator-based anti-blockage structure has many inherent drawbacks in actual landscape architecture applications. It not only fails to address the root causes of arching and rodent burrow blockages but also introduces new malfunctions and defects, further degrading the quality of fertilization operations.

[0005] First, existing mixing structures mostly rely on electric motor drives, requiring supporting circuits, power supplies, and control components. The outdoor working environment in gardens is often dusty and prone to moisture, easily leading to circuit failures and motor damage, resulting in high equipment failure rates, cumbersome maintenance, and poor adaptability and stability. Second, traditional mixing components rotate continuously after the machine is powered on. Regardless of whether the equipment is being pushed or there is material flow during fertilization, the mixing components continuously mechanically disturb the fertilizer in the bin. The slow-release granular fertilizer used in gardens is relatively brittle; long-term, repeated mixing and crushing will cause the intact fertilizer particles to break, producing a large amount of fertilizer debris. This not only directly damages the slow-release structure of the fertilizer, leading to rapid nutrient volatilization and loss, and a significant decrease in fertility, but also reduces the effectiveness of garden fertilization and maintenance. More importantly, the fine powder produced by fertilizer crushing is more viscous and less fluid, easily adhering to the inner wall of the hopper and the surface of the mixing components. This continuous accumulation and solidification further exacerbates the problems of material sticking to the walls and clumping, increasing the probability of hopper blockage and creating a vicious cycle of "mixing and crushing fertilizer—fine powder sticking to the walls—exacerbating blockage." Simultaneously, traditional mixing structures have a fixed rotation speed, making them unsuitable for the varied working conditions in gardening: insufficient mixing force during low-speed, fine-tuning operations makes it difficult to effectively break up bridging and rat holes; excessive mixing intensity during high-speed operations further exacerbates fertilizer crushing, failing to balance anti-blocking effectiveness with fertilizer integrity. Furthermore, the numerous and complex components of electrically controlled mixing structures result in high manufacturing costs and difficult disassembly and maintenance, hindering the widespread application of small, hand-push garden fertilization equipment.

[0006] In summary, the existing rotary stirring anti-clogging structure cannot effectively meet the needs of refined fertilization in landscape gardening. It suffers from many defects, such as high failure rate, severe fertilizer breakage, large fertilizer loss, recurring clogging problems, and poor adaptability to working conditions. Therefore, there is an urgent need to design a purely mechanical soil loosening and fertilization machine for landscape gardening that can disturb the soil as needed, simultaneously break up burrows and rat holes, and improve the integrity of fertilizer, so as to solve many technical pain points of the existing technology. Summary of the Invention

[0007] In view of this, the present invention proposes an integrated soil loosening and fertilizing machine for landscape gardening to solve the problems existing in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a landscape garden soil loosening and fertilizing integrated machine, comprising: a frame, a push handle, and wheels, wherein the push handle is fixed to the rear end of the frame, and the wheels are rotatably connected to the front end of the push handle, and further comprising: a hopper, a disc body, and a second component. The second component includes a bracket fixedly connected to the top of the inner cavity of the hopper. A guide vane is fixedly connected to the bracket by screws. A return spring A is fixedly connected inside the cylindrical cavity in the middle of the bracket. An inner sliding column is fixedly connected to the bottom of the return spring A. The inner sliding column slides within the cylindrical cavity in the middle of the bracket. A vertical rod is fixedly connected to the bottom end of the inner sliding column, a limit rod is fixedly connected to the upper part of the vertical rod, and a magnet B is embedded in the cone at the lower end of the vertical rod. The disc body is equidistantly surrounded and fixedly connected with magnet A, which is magnetically attracted to magnet B.

[0009] As a preferred option, a third component is also included; The third component includes a support fixed to a vertical rod, a transverse rod sliding laterally inside the support, an auxiliary block fixedly connected to the transverse rod, a protruding partition inside the support, and a return spring B symmetrically fixedly connected to the partition. The end of the return spring B away from the partition is fixedly connected to the auxiliary block. A slanted hole is provided through the transverse rod, and a plow and harrow component is fixedly connected to the transverse rod. Magnets C are embedded in both ends of the plow and harrow component. The outer wall of the silo is fixedly connected with magnetic components.

[0010] As a preferred embodiment, a first component is also included; The first component includes an engine mounted on a frame, and a transmission system is fixedly connected to the transmission end of the engine. The transmission system consists of a drive shaft, pulleys, and belts. One of the belts in the transmission system is connected to the axle of a wheel, and a driven shaft is connected to the other belt. The disc body is fixedly connected to the driven shaft, and the upper surface of the frame is fixedly connected to the support legs. A protective shell is fixedly connected to the support legs by screws, and the disc body is placed inside the protective shell. The hopper is located above the disc body, the disc body is provided with a storage trough, and the bottom of the protective shell is fixedly connected to a guide strip; The bottom of the frame is fixedly connected to a soil loosening component and a soil covering component; with the direction of the wheel as the starting point, the soil loosening component, the guide strip, and the soil covering component are distributed in sequence.

[0011] Preferably, the protective shell is composed of two semi-circular shells spliced ​​together; the two semi-circular shells are fixed to the support legs by bolts, and each of them is provided with a material port. The hopper is connected to the guide bar through the upper and lower material ports provided on the protective shell.

[0012] Preferably, the bracket, guide vane, vertical rod, limiting rod, and horizontal rod constitute a grid system.

[0013] Preferably, the guide vane is in a downwardly outward tilting V-shape.

[0014] Preferably, the support, transverse rod, auxiliary block, return spring B, oblique hole, plow and rake parts and two magnets C constitute a particle processing group. In this design, two groups are provided, which are arranged in a cross shape on the vertical rod and located at different heights.

[0015] Preferably, the magnetic assembly consists of a mounting base and a magnetic block, and the magnet C and the magnetic block of the magnetic assembly are magnetically repelled; two mounting bases with magnetic blocks are symmetrically and alternately fixed on the outer wall of the hopper, and when set up, their vertical plane is coplanar with the particle processing group.

[0016] Compared with the prior art, the present invention provides a soil loosening and fertilizing machine for landscape gardening, which has the following beneficial effects: 1. The present invention, through the cooperative design of the second and third components, can bring the following advantages: This design reduces the generation of fine powder, breaking the vicious cycle of "composted fertilizer - sticking to the wall - re-clogging": Existing rotating mixing structures continuously agitate and generate a large amount of fine fertilizer powder. This powder is highly adhesive and easily adheres to the silo walls, further exacerbating material accumulation, agglomeration, and secondary clogging. This design eliminates forced mixing and crushing actions, using vertical piercing and horizontal loosening to break up arches and rat holes throughout the process. It avoids grinding and generating fine powder materials, reducing fertilizer sticking to the walls and solidifying at the source. This breaks the vicious cycle caused by traditional mixing structures, resulting in cleaner and smoother material discharge from the silo, with no material residue after long-term operation. This device achieves adaptive disturbance operation, avoiding long-term agitation and breakage of fertilizers, and ensuring fertilizer integrity and original fertility: It relies on mechanical linkage triggering during equipment movement, generating vertical reciprocating "arch-breaking" motion and lateral "mouse hole-breaking" action only when the equipment is pushed forward. When the equipment is stopped and stationary, the overall disturbance structure remains synchronously still, without any ineffective mechanical disturbance. Unlike traditional mixing structures that continuously agitate after being powered on, this effectively avoids the problem of fertilizers being crushed, rubbed, and broken over a long period. It effectively preserves the complete granular shape of slow-release granular fertilizers and garden organic fertilizers, preventing damage to the slow-release structure, preventing nutrient volatilization and loss, and significantly improving the effectiveness of garden fertilization and maintenance. This solves the core pain point of existing technologies where long-term disturbance leads to decreased fertility.

[0017] 2. This invention, through its built-in grid flow guiding system, achieves pre-application optimization during the fertilization and injection stage, offering the following benefits: Achieving uniform fertilizer distribution during manual granular fertilizer application: The downward-sloping, outward-curving, figure-eight-shaped guide wings provide flexible buffering and guidance for the vertically falling fertilizer flow. This allows the fertilizer, initially concentrated at the center of the hopper, to be evenly distributed to both sides, preventing concentrated accumulation and compaction directly above the outlet. This effectively improves upon traditional feeding methods, addressing issues of central accumulation and localized high compaction, and achieving uniform circumferential distribution within the hopper. It significantly reduces the impact pressure of fertilizer falling from a height, preventing granules from being crushed and compacted. This reduces fertilizer granule breakage and dust generation during the feeding stage, and avoids the undesirable accumulation pattern of excessive central compaction and suspended peripheral fertilizer, thus mitigating the prerequisites for bridging formation. The passive grid system alters the material's cohesion: While the guide vanes divert the flow, supports, vertical rods, and horizontal rods distributed at different heights and positions in the silo form a three-dimensional grid system. This creates a multi-layered diversion and diffused distribution effect for the falling fertilizer, effectively dispersing the concentrated fertilizer flow, suppressing particle size grading, avoiding the problems of large particles adhering to the walls and fine powder accumulating in the middle, reducing the increase in material cohesion and decreased flowability caused by fine powder filling the gaps between large particles, and preventing the premature formation of local tubular voids and static consolidation layers during the feeding stage. This effectively prevents the pre-forming defects of rat holes unique to inverted cone-shaped silos. This passive grid system operates without any active movement or mechanical compaction. It optimizes fertilizer accumulation and flow through structural morphology, achieving pre-forming protection against compaction, grading, arching, and rodent burrowing without damaging fertilizer granules or causing fine powder to stick to the walls. This works in conjunction with the active dynamic arch-breaking and rodent-burrow-breaking structures formed by the second and third components during operation to create a closed-loop anti-blocking system. This effectively solves the technical shortcomings of traditional fertilizer applicators that rely solely on post-mixing remediation and cannot prevent blockages at the source.

[0018] 3. The present invention, by adding an oblique hole structure to the transverse component, can bring the following advantages: This structure penetrates and clears the gaps between granules, eliminating the accumulation and locking of fine powder, and weakening the cohesive force of the material: When granular fertilizers used in landscaping become damp, their surface becomes sticky, and fine powder easily fills the gaps between large granules, causing them to become interlocked and locked, significantly increasing internal friction and cohesion. This results in the fertilizer losing its overall flowability, only flowing through localized, single-point collapses, which is the core cause of repeated rat burrow formation. This structure features oblique holes on the transverse components. As the transverse components move up and down through the fertilizer layer, the fertilizer granules and the oblique holes create a staggered penetration and gap-clearing effect. This effectively scrapes and clears the fine powder interlayers filling the gaps between large granules, disrupting the granule's solidified interlocking structure, weakening the overall cohesive force of the material, and restoring the fertilizer's loose flow characteristics. This overcomes the shortcomings of traditional structures that only disturb the surface and cannot solve the problem of deep granule gap locking. This design achieves particle displacement and replacement, breaking local static dead zones and preventing rat hole regeneration: Traditional anti-blocking structures can only achieve local swinging and dispersion, but cannot change the overall flow trend of fertilizer. The fertilizer around the side wall of the inverted cone-shaped silo remains in a static and solidified state for a long time, making it very easy to form tubular rat holes again. In this design, during the upward movement of the transverse component, some fertilizer particles pass through the oblique holes to achieve cross-layer displacement and cross-replacement, so that the originally fixed and static side wall solidified fertilizer, central flow fertilizer, and upper layer accumulated fertilizer form a dynamic exchange flow, breaking the single flow state of "central flow and peripheral stillness", and causing the fertilizer in the silo to change from local single-point collapse flow to overall uniform dispersion, thus avoiding the conditions for rat hole formation from the flow mechanism. With a simple structure and no derivative defects, it significantly improves the anti-clogging performance without changing the original advantages: the oblique hole is a passive structure that requires no additional power, electrical control and moving parts; at the same time, it makes up for the shortcomings of simple lateral extension and contraction which can only cause surface disturbance, and achieves the anti-clogging effect of "breaking arches + breaking rat holes + clearing gaps + guiding material flow", which greatly improves the adaptability of the equipment to complex fertilizer working conditions.

[0019] 4. This invention, through its purely mechanical magnetic linkage and non-electrical control design, offers the following advantages: Abandoning reliance on electrical control significantly improves environmental adaptability: The entire process adopts a pure mechanical magnetic linkage structure, eliminating the need for electrical components such as motors, circuits, and control lines. It can fully adapt to the dusty, humid, rainy, and complex working environments of landscape gardens, avoiding the defects of traditional electrically controlled mixing structures that are prone to moisture, dust accumulation, short circuits, and frequent motor burnout. With a simple and reliable structure, the failure rate is significantly reduced: various electrical components are eliminated, resulting in fewer overall parts and a simpler transmission logic. There are no hidden dangers such as electrical aging, circuit faults, or controller malfunctions. Mechanical linkage wear is minimal, and the working stability is strong, making it less prone to failure during long-term continuous field operations. Moreover, the purely mechanical modular layout is free from complex circuit constraints, making subsequent disassembly, maintenance, internal cleaning, and component replacement simpler and more convenient. No professional electrician is required for maintenance, disassembly, and cleaning, resulting in low daily maintenance costs and better economic efficiency. Attached Figure Description

Detailed Implementation

[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0024] Example Please refer to Figures 4 to 9 As shown: To address the problems mentioned in the technical solutions, this application provides a landscape garden soil loosening and fertilizing integrated machine, including: a frame 1, a push handle 2, and wheels 3. The push handle 2 is fixed to the tail end of the frame 1, and the wheels 3 are rotatably connected to the front end of the push handle 2. It also includes: a hopper 404, a disc body 407, and a second component. The second component includes a bracket 501 fixedly connected to the top of the inner cavity of the hopper 404. A guide vane 502 is fixedly connected to the bracket 501 by screws. A return spring A503 is fixedly connected to the cylindrical cavity in the middle of the bracket 501. An inner sliding column 504 is fixedly connected to the bottom of the return spring A503. The inner sliding column 504 slides within the cylindrical cavity in the middle of the bracket 501. A vertical rod 505 is fixedly connected to the bottom of the inner sliding column 504. A limit rod 506 is fixedly connected to the upper part of the vertical rod 505. A magnet B508 is embedded in the cone at the lower end of the vertical rod 505. The disc 407 is equidistantly surrounded by magnets A507, which are magnetically attracted to magnets B508.

[0025] in: The second component works in conjunction with the horizontal bar 602 to achieve the effects of guiding flow, preventing grading, preventing bridging, and preforming rat holes during fertilizer filling (passive anti-clogging design). Specifically, the downward-sloping outward-curving arc-shaped guide wing 502 is V-shaped with a smooth, rounded surface and no sharp edges. When fertilizer is poured in, it flows along the guide wing 502 to the left and right side walls of the hopper 404, achieving uniform circumferential distribution and preventing clogging in the middle. It also buffers the impact of falling material, preventing fertilizer from falling from a height and compacting, reducing particle breakage and dust. At the same time, the bracket 501, guide wing 502, vertical bar 505, limiting bar 506, and horizontal bar 602 are distributed at different positions and heights in the hopper 404, which is equivalent to having a built-in diversion grid in the hopper 404 to achieve hidden zoning. The above design can effectively reduce the phenomena of "arching" and "rat holes" during fertilizer filling.

[0026] The grid system consists of bracket 501, guide vane 502, vertical rod 505, limiting rod 506, and horizontal rod 602.

[0027] The guide vane 502 is in the shape of a downwardly tilted figure eight; it is fixed to the bracket 501 by screws.

[0028] The return spring A503 is used for the reset of the inner slide 504.

[0029] The vertical rod 505, which moves up and down, can break the "arching" phenomenon formed by granular fertilizer; and a conical part is fixedly connected to the bottom of the vertical rod 505, which can be used to assist in guiding the flow of granular fertilizer.

[0030] When magnet A507 in the disc 407 magnetically attracts magnet B508 in the tapered part at the bottom of vertical rod 505, vertical rod 505 will move downwards. Furthermore, when magnet A507 and magnet B508 are no longer on the same straight line, vertical rod 505 will indirectly move upwards under the action of return spring A503. At this time, limit rod 506 is used to limit the upward movement height of vertical rod 505, to prevent its upward movement from causing horizontal rod 602 to cause a large disturbance to the granular fertilizer in hopper 404, resulting in fertilizer falling out of hopper 404.

[0031] The number of magnets A507 can be increased or decreased according to specific needs, thereby adjusting the number of up-and-down reciprocating movements of the vertical rod 505 when the disc 407 rotates once, thus adjusting the number of times the single periodic arch-breaking action is performed, and adapting it to fertilizers of different particle sizes.

[0032] Magnet A507 and magnet B508 are magnetically attracted to each other.

[0033] A further embodiment: Please refer to Figures 1 to 7 As shown: The third component includes a support 601 fixed to a vertical rod 505, a transverse rod 602 sliding laterally inside the support 601, an auxiliary block 603 fixedly connected to the transverse rod 602, a protruding partition strip inside the support 601, a return spring B604 symmetrically fixedly connected to the partition strip, and the end of the return spring B604 away from the partition strip being fixedly connected to the auxiliary block 603; an oblique hole 605 is opened through the transverse rod 602, a plowing rake 606 is fixedly connected to the transverse rod 602, and magnets C607 are embedded in both ends of the plowing rake 606; a magnetic assembly 608 is fixedly connected to the outer wall of the hopper 404.

[0034] in: The third component works in conjunction with the second component to prevent clogging of the granular fertilizer within the 404 hopper, ensuring the effectiveness of soil loosening and fertilization in landscaping. (Active anti-clogging design) The support 601 has a raised spacer inside, and the return spring B604 can be symmetrically fixed on the spacer.

[0035] The oblique hole 605 is used to transfer and disturb the granular fertilizer in the hopper 404 during the up-down and left-right movement of the transverse rod 602.

[0036] The plow and harrow component 606 is used to disturb the granular fertilizer in the hopper 404, reduce its local compaction, and prevent the occurrence of "rat holes".

[0037] The support 601, the horizontal rod 602, the auxiliary block 603, the return spring B604, the oblique hole 605, the plow and rake part 606, and the two magnets C607 constitute the particle processing group. There are two groups in this design, which are arranged in a cross shape on the vertical rod 505 and located at different heights on it; they can be added or removed according to specific circumstances.

[0038] The particle processing unit is indirectly connected to the bracket 501 via the return spring A503. When maintenance is required, the bracket 501 can be disassembled to perform overall maintenance.

[0039] The magnets C607 and the magnetic component 608 repel each other magnetically.

[0040] The magnetic assembly 608 consists of a mounting base and a magnetic block; two mounting bases with magnetic blocks are symmetrically and alternately fixed on the outer wall of the hopper 404 (i.e., the two magnetic assembly components 608 are located on the same vertical plane, but at different heights). During operation, when the magnet C607 in the granule processing group is coplanar with it, the horizontal rod 602 can be moved laterally through magnetic action, thereby disturbing the fertilizer in the hopper 404; the number can be increased or decreased according to specific circumstances.

[0041] When the reset spring A503 moves the granule processing assembly up and down, the magnet C607 embedded in one end of the transverse rod 602 gradually moves to the height of the magnetic assembly component 608 of one of the mounting bases with magnetic blocks, and they repel each other under the action of magnetism. At this time, the transverse rod 602 will move laterally away from the magnetic assembly component 608. Further, as the magnet C607 leaves the line where the magnetic assembly component 608 is located, the transverse rod 602 will be reset with the assistance of the auxiliary block 603 and the reset spring B604. Further still, as the reset spring A503 continues to move it, the magnet C607 embedded in the other end of the transverse rod 602 will gradually move to the height of the magnetic assembly component 608 of another mounting base with magnetic blocks. At this time, the transverse rod 602 will be forced to move laterally in the opposite direction. Thus, the transverse rod 602 has completed a complete transverse reciprocating movement. This reciprocating movement can disturb the granular fertilizer in the hopper 404 and avoid abnormal blockage.

[0042] A further embodiment: Please refer to Figures 4 to 10 As shown: The first component includes an engine 401 mounted on a frame 1. A transmission system 402 is fixedly connected to the transmission end of the engine 401. The transmission system 402 consists of a drive shaft, pulleys, and belts. One belt of the transmission system 402 is connected to the axle of the wheel 3, and a driven shaft 403 is connected to the driven shaft 403. A disc 407 is fixedly connected to the driven shaft 403. A support leg 405 is fixedly connected to the upper surface of the frame 1. A protective shell 406 is fixedly connected to the support leg 405 by screws. The disc 407 is located inside the protective shell 406. A hopper 404 is located above the disc 407. A storage trough 408 is provided on the disc 407. A guide strip 409 is fixedly connected to the bottom of the protective shell 406. A loosening component 410 and a covering component 411 are fixedly connected to the bottom of the frame 1. The loosening component 410, the guide strip 409, and the covering component 411 are distributed sequentially with the direction of the wheel 3 as the starting point.

[0043] in: The first component is used for integrated soil loosening and fertilization in gardens; specifically, it achieves coordinated loosening, fertilization, and soil covering.

[0044] The engine 401 drives the transmission system 402 to rotate the wheels 3 and the driven shaft 403 that drives the fertilizing disc 407. By connecting the equipment's movement and fertilization with the same drive, it can effectively achieve the coordination of fertilization when moving and stopping fertilization when not moving. Moreover, since the two share a common drive source, when the equipment moves faster, the fertilizing disc 407 will also rotate more freely, and there will be no situation where the equipment moves too fast and the amount of fertilizer is insufficient.

[0045] The transmission system 402 consists of a drive shaft, pulleys, and belts; one belt of the transmission system 402 is connected to the axle of the wheel 3, and the other belt is connected to the driven shaft 403.

[0046] The 404 refractory plastic hopper is filled with granular fertilizer needed for garden trees, flowers and other plants.

[0047] Concept Explanation: Definition of "Arching" and "Rat Hole" in Granular Fertilizer (Clogged feed inlet is caused by the phenomena of "arching" and "rat hole"). Arching (also called arching or bridging): Under the combined action of internal friction, particle cohesion, and silo wall friction, the fertilizer layer above the discharge port in silo 404 forms a suspended and solidified arch structure, like an arch bridge spanning the middle and lower part of silo 404; the discharge position below the arch is completely suspended and hollow, and the fertilizer above is supported by the arch, so the whole thing is suspended and does not discharge, resulting in blockage phenomena such as interruption of material discharge and fertilizer discharge.

[0048] Rat burrow (cavity flow): When fertilizer is poured, the fertilizer's own weight puts great pressure on it, causing it to compact and solidify, preventing it from collapsing and flowing again. During fertilizer transport, the fertilizer in the silo 404 forms only a narrow vertical flow channel in the center. The fertilizer in the channel flows down along the small hole, while most of the fertilizer around the channel remains tightly attached to the silo wall, solidified and stationary, and does not slide towards the center to replenish it; it resembles a burrow dug by a rat, hence the name rat burrow.

[0049] The protective shell 406 is composed of two semi-circular shells; the two semi-circular shells are fixed to the support legs 405 by bolts, and each of them has a material port. The hopper 404 is connected to the guide bar 409 through the upper and lower material ports opened on the protective shell 406.

[0050] When loosening the soil and applying fertilizer, the 408 with different numbers of storage troughs can be replaced according to the needs of the soil to be treated, so as to adapt the amount of fertilizer per unit length.

[0051] When the rotating disc 407 aligns the storage trough 408 with the bottom discharge port of the hopper 404 and the loading port of the protective shell 406, the fertilizer in the hopper 404 will enter the storage trough 408. Then, as the disc 407 continues to rotate, it will block the bottom discharge port of the hopper 404. At this time, the disc 407 will continue to move through the storage trough 408 with the fertilizer it just received until it overlaps with the discharge port of the protective shell 406. Then, the fertilizer will be transferred and transported through the guide bar 409 to the soil that has just been loosened by the loosening component 410.

[0052] Starting from the direction of wheel 3, the loosening component 410, the guide strip 409, and the covering component 411 are distributed in sequence.

[0053] The working principle of all the content in the above embodiments is as follows: This equipment is a purely mechanical, non-electrically controlled, hand-push garden maintenance device. During operation, it simultaneously completes the integrated operation of loosening soil, quantitative fertilization, and soil covering. The 404 slurry bin uses a dual mechanism of passive grid guidance and active magnetic attraction to break arches and rat holes, avoiding problems such as crushed fertilizer, sticking to the wall, and blockage.

[0054] Feeding and passive anti-clogging (pre-treatment): Granular fertilizer is added to the silo 404. When the fertilizer falls, it first contacts the guide vane 502. The outward-sloping, V-shaped guide vane 502 distributes the concentrated material flow evenly to both sides of the silo 404, avoiding compaction of the material in the center.

[0055] The supports 501, vertical rods 505, limiting rods 506, and horizontal rods 602 located at different heights within the silo 404 constitute a three-dimensional grid system, which diverts fertilizer through multiple layers, inhibits particle grading, and prevents arching and pre-forming of rat holes.

[0056] Power-on and travel drive: Start the engine 401, which drives the transmission system 402 to operate. The transmission system 402 simultaneously drives two actuators: the drive wheel 3 axle, which allows the whole machine to be pushed forward; and the driven shaft 403 to rotate, which causes the disc 407 to rotate at a constant speed inside the protective shell 406.

[0057] Quantitative fertilization and soil application (first component operation): When the storage trough 408 on the disc 407 rotates to the bottom of the hopper 404, it receives the falling fertilizer; then the disc 407 continues to rotate, the storage trough 408 aligns with the discharge port of the protective shell 406, and the fertilizer falls into the guide bar 409.

[0058] When the machine moves forward, the loosening component 410 at the bottom of the frame 1 breaks up the compacted soil.

[0059] The guide bar 409 precisely delivers the fertilizer into the loosening trench, and then the covering component 411 pushes the soil back to cover the fertilizer.

[0060] Vertical arch breaking (second component in operation): During the loosening of soil and fertilization, the disc 407 rotates, and the magnet B508 inside it periodically rotates to the area directly below the hopper 404; the magnet B508 is magnetically attracted to the magnet A507 at the bottom of the vertical rod 505, but they do not make contact, thus pulling the vertical rod 505 downward.

[0061] The vertical rod 505 drives the inner sliding column 504 to slide down along the middle cavity of the bracket 501, stretching the return spring A503.

[0062] After magnet B508 rotates away, the attraction disappears, the return spring A503 rebounds, pulling the vertical rod 505 upward to reset, and the limit rod 506 limits the upward height.

[0063] The vertical rod 505 pierces back and forth to break up fertilizer bridging and ensure smooth material flow.

[0064] Horizontal rat holes and gaps (third component in operation) When the vertical rod 505 moves up and down, it drives the support 601 and the horizontal rod 602 to rise and fall synchronously.

[0065] The magnet C607 on the horizontal bar 602 moves as it is lifted and passes the magnetic assembly 608 on the outer wall of the hopper 404.

[0066] Magnet C607 and magnetic component 608 repel each other magnetically, pushing the transverse rod 602 to extend laterally into the compartment and compressing the reset spring B604; further, after magnet C607 leaves the repulsive area, the reset spring B604 pushes the auxiliary block 603, causing the transverse rod 602 to retract and return to its original position.

[0067] The horizontal bar 602 reciprocates and extends, working in conjunction with the plow and harrow 606 to loosen the stationary fertilizer around the bin walls and break up rat holes; The oblique holes 605 on the transverse rod 602 penetrate the gaps between particles as it moves up and down, guiding fine powder, weakening cohesion, and allowing the fertilizer to flow evenly as a whole.

[0068] Shutdown status: When the engine is shut down (401), the transmission system (402), wheels (3), and disc body (407) all stop operating.

[0069] Vertical rod 505 and horizontal rod 602 stop moving, preventing additional disturbance and avoiding fertilizer from being left to stand still, breaking, or sticking to the wall.
