Description

Technical Field

[0001] This invention relates to the field of organic substrate preparation technology, and more specifically, to an organic substrate preparation device and preparation method suitable for rose cultivation. Background Technology

[0002] Currently, in the fermentation preparation process of rose-specific organic substrate, operators typically need to put crushed branches, well-rotted manure, coconut coir, and other raw materials into a fixed fermentation chamber or tank. To promote aerobic activity of microorganisms and ensure uniform decomposition of materials, stirring is an indispensable step. However, existing equipment generally suffers from low stirring efficiency. Its stirring mechanism is often simply designed, for example, using a single-axis straight blade. During operation, it can only move the material in the central area of ​​the tank to a limited extent, while the material layer close to the inner wall and the material in the corner areas remain in a relatively static "dead corner" state for a long time. This insufficient stirring first leads to serious temperature stratification and uneven oxygen distribution: the core of the tank may become excessively hot due to the activity of microorganisms, even exceeding 70°C, while the temperature in the corner areas is insufficient and cannot reach the high temperature threshold required to kill pathogens and weed seeds. At the same time, a large amount of material falls into an anaerobic environment because it cannot come into contact with fresh air. This not only slows down the fermentation process and forces the cycle to be prolonged, but also breeds anaerobic bacteria, producing an unpleasant rancid or ammonia odor, which seriously affects the quality of the finished substrate.

[0003] The limitations of existing equipment mechanical design are twofold. Firstly, the stirring power is often insufficient to cope with the changing viscosity of materials during fermentation (especially the caking stage at high temperatures), causing the agitator to stop or idle when resistance is at its maximum. Secondly, the shape and trajectory of the stirring blades have not been specifically optimized, lacking effective radial and axial tumbling capabilities and the ability to scrape the tank walls. This results in viscous materials adhering layer by layer to the tank walls, forming a thick insulating and inert layer, further hindering heat conduction and mass exchange. The impact of these mechanical defects is far-reaching, directly affecting… This results in extremely heterogeneous fermentation products—in the same batch of substrate, some parts may be fully decomposed, while others are still raw or semi-raw. Planting roses with such unstable, incompletely decomposed substrate is like planting hidden dangers: it may undergo secondary fermentation in the flowerpot or soil, competing for nitrogen and causing the plants to turn yellow; continuous heat release will damage the delicate root system; and pathogens that are not killed may directly cause soil-borne diseases such as root rot. Therefore, insufficient mixing is not just a matter of engineering efficiency, but a key technical bottleneck that determines whether organic substrates can successfully serve the healthy cultivation of roses. Summary of the Invention

[0004] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides an organic substrate preparation device and preparation method suitable for rose cultivation, so as to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: an organic substrate preparation device suitable for rose cultivation, comprising a telescopic mechanism and a one-way mechanism; The telescopic mechanism includes a bidirectional mechanism and a driving mechanism. The telescopic mechanism provides not only circumferential stirring torque but also vertical mixing torque, thus ensuring that the organic matter is fully stirred in multiple directions. The bidirectional mechanism will produce irregular vertical movement as the circumferential stirring occurs, and the vertical movement will enhance the degree of stirring of organic matter in the vertical direction. The drive mechanism provides the power for stirring the entire device, thereby ensuring the fermentation effect of organic matter; The unidirectional mechanism ensures that the force is applied only on one side during stirring, while the other side is subjected to elastic force, making the overall connection flexible. This reduces rigid connections during stirring, generates more irregular stirring directions, and thus improves the stirring effect.

[0006] Preferably, the telescopic mechanism includes a fermentation shell and a heating shell, with the fermentation shell fitted inside the heating shell. The heating shell generates a suitable temperature for fermentation, thereby ensuring the quality of organic matter fermentation inside the fermentation shell.

[0007] Preferably, the bidirectional mechanism includes a lower stirring sleeve and an upper stirring sleeve that are rotatably connected to the inner wall of the fermentation shell. The upper stirring sleeve is located above the lower stirring sleeve. Multiple stirring blades are installed at equal intervals on the inner walls of the lower stirring sleeve and the upper stirring sleeve, respectively. The lower stirring sleeve, the upper stirring sleeve and the stirring blades ensure effective stirring of organic matter.

[0008] Preferably, two layers of outer ball sleeves are installed at equal intervals on the inner walls of the lower and upper stirring sleeves, respectively. Rolling balls are rotatably connected inside the two sets of outer ball sleeves at the upper end, and each rolling ball is equipped with a side rod arranged obliquely downwards. A rolling ball is provided at the other end of the side rod. Multiple rolling balls located on the same plane and obliquely downwards are rotatably connected to inner ball sleeves. Rolling balls are also rotatably arranged inside the two sets of outer ball sleeves at the lower end, and multiple rolling balls are provided with side rods arranged obliquely upwards. The rolling ball at the other end of the side rod is rotatably connected inside the inner ball sleeve. Two retaining rings are provided on each side rod, and a rotating blade is rotatably arranged on the side rod. The rotating blade is respectively attached between the two retaining rings.

[0009] Preferably, the four inner ball sleeves with their upper ends on the same plane are respectively disposed on the outer wall of the cross sleeve, and the four inner ball sleeves with their lower ends on the same plane are also respectively disposed on the outer wall of another cross sleeve, and the two cross sleeves are coaxially disposed.

[0010] Preferably, the driving mechanism includes a motor fixedly mounted on the heating shell, a drive shaft connected to the extended end of the motor, two cross sleeves rotatably connected to the drive shaft, and a material pipe connected to the upper end of the heating shell, which can be sealed by external equipment.

[0011] Preferably, the drive mechanism further includes a fixedly mounted bracket, the heating shell is rotatably connected to the bracket, a worm gear is provided on the side wall of the heating shell, and a worm is rotatably mounted on the side wall of the bracket, with the worm gear meshing with the worm.

[0012] Preferably, the one-way mechanism includes an intermediate disk sleeved on a drive shaft. The intermediate disk contains multiple vertical bars, which are slidably connected within the drive shaft. The inner wall of the intermediate disk has two groups of equally spaced upper and lower inclined grooves, with the axes of the upper and lower inclined grooves forming a 45-degree angle with the upper end face of the intermediate disk. Each of the upper and lower inclined grooves has a slidably connected inclined rod, and each inclined rod has a top spring that abuts against the intermediate disk. One-way disks are coaxially fitted on both sides of the intermediate disk, each one-way disk having multiple one-way grooves. The inclined rods are respectively engaged within the one-way grooves. Two symmetrically fitted sleeves are arranged between every two one-way disks, and the two sleeves are connected by bolts.

[0013] Preferably, each pair of symmetrically arranged one-way discs is provided with an upper torsion spring and a lower torsion spring, and each pair of adjacent upper and lower torsion springs are connected to the two sides of the cross sleeve, and the upper and lower torsion springs rotate in the same direction.

[0014] This invention provides a method for preparing an organic substrate suitable for rose cultivation, comprising the following steps: First stage: power input and one-way locking. The motor starts, drives the transmission shaft and the intermediate disk connected to it to rotate. The inclined rod on the rotating intermediate disk, under the action of centrifugal force and inclined plane, has its head embedded in the one-way groove on the one-way disk that matches its rotation direction, thus realizing one-way transmission locking on this side. The second stage: flexible torque transmission and motion decomposition. The rotational tendency of the locked one-way disc is flexibly transmitted to the upper and lower cross sleeves through the upper and lower torsion springs. The rotation of each cross sleeve is driven by multiple side rods that are hinged to it and arranged in a spatially oblique direction, thus pushing the upper and lower stirring sleeves. This process decomposes the pure rotational motion of the cross sleeves into a composite motion in which the stirring sleeves both revolve around the axis and move towards or away from each other along the axis. The third stage: multi-dimensional stirring and overload buffering. The upper and lower stirring sleeves and their stirring blades move axially while performing circumferential stirring, realizing three-dimensional tumbling of organic matter. The flexible connection characteristics of the torsion spring can absorb the impact caused by sudden changes in material resistance and avoid damage to rigid transmission. At the same time, the self-rotating blades on the side rods rotate freely in the fluid, enhancing local mixing. Fourth stage: motion reversal and material discharge preparation. When the transmission phase changes or the stirring direction needs to be changed, the inclined rod on the other side of the middle plate engages with the corresponding one-way groove, the driving direction changes, and the stirring sleeve moves in the opposite axial direction. After fermentation, the worm gear can drive the worm wheel to tilt the entire heating shell and fermentation shell, and the stirring blades will discharge the material.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides an organic substrate preparation device and method suitable for rose cultivation, which has the following beneficial effects: This invention achieves multi-dimensional composite stirring, significantly improving mixing uniformity and fermentation efficiency. Through a unique spatial linkage (side rod, inner / outer ball sleeve) and flexible transmission (one-way mechanism) design, the unidirectional rotation of the drive shaft is intelligently decomposed into the superposition of circumferential revolution and axial reciprocating motion of the stirring components (upper / lower stirring sleeve). The stirring blades not only rotate around the axis, but also move toward or away from each other in a regular manner, thereby producing a comprehensive "turning, cutting, kneading and pushing" effect on the organic matter in three-dimensional space. This effectively breaks the concentration gradient and temperature stratification, ensuring full contact between the microbial community, nutrients and oxygen, and greatly improving the uniformity and speed of the fermentation reaction.

[0016] With adaptive flexible transmission characteristics, the equipment's reliability and adaptability to different materials are greatly improved. The core transmission path introduces a one-way mechanism consisting of a one-way disc, a slant bar, and torsion springs (upper / lower torsion springs). This mechanism not only realizes the directional transmission of motion, but more importantly, the flexible connection of the torsion springs allows the stirring components to generate instantaneous slip or buffer when encountering local high resistance (such as hard lumps), rather than rigid resistance. This design can automatically absorb impact loads, prevent motor stall or overload damage to transmission components, and enable the equipment to safely and smoothly process complex organic materials with uneven viscosity and density.

[0017] The stirring motion combines regularity and randomness, effectively preventing agglomeration and promoting micro-mixing. On the one hand, the amplitude and period of axial movement are controlled by the tilt angle of the inclined rod and the transmission rhythm. On the other hand, the energy storage and release of the flexible torsion spring when transmitting torque causes slight, nonlinear changes in the instantaneous motion trajectory of the stirring component. In addition, the rotating blades on the side rod rotate freely under fluid resistance, increasing the local turbulence intensity. This "macroscopically ordered, microscopically random" motion mode is particularly suitable for breaking fiber agglomeration and preventing sedimentation and crust formation, achieving more thorough micro-mixing.

[0018] With a compact structure, high functional integration, and low operating energy consumption and maintenance costs, the entire mechanism that converts rotary motion into compound stirring motion is integrated in the central axis area of ​​the fermentation vessel. It does not require a complex external linear drive device. Through ingenious mechanical linkage (cross sleeve, side rod, etc.), it reuses a single drive source (motor) to achieve multi-degree-of-freedom output. The energy consumption is concentrated and the efficiency is high. The main moving parts are connected to the rolling ball through the ball sleeve, resulting in low frictional resistance and good durability. The overall structure is simple and reliable, reducing manufacturing and long-term maintenance costs. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0023] In this invention, unless otherwise stated, the directional terms such as "up" and "down" generally refer to the directions shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not intended to limit this invention.

[0024] Please see Figures 1 to 9 This embodiment provides an organic substrate preparation device suitable for rose cultivation, the core of which is a telescopic mechanism 11. The telescopic mechanism 11 is installed inside a fermentation shell 12, which is enclosed by a heating shell 13. The heating shell 13 provides and maintains the optimal temperature environment required for fermentation. The entire telescopic mechanism 11 consists of a bidirectional mechanism 21 and a drive mechanism 31, which work together to transform a single rotary input into a composite motion that combines circumferential stirring and axial mixing.

[0025] 1. Fermentation chamber and basic frame The fermentation shell 12 is used to contain the organic raw materials to be fermented and is coaxially fitted inside the heating shell 13. The heating shell 13 is temperature-controlled by an external device (not shown in the figure). The heating shell 13 is rotatably mounted on a fixed bracket 35 via bearings. A worm gear 36 is fixed on the outer wall of the heating shell 13, and a worm 37 is rotatably mounted on the bracket 35 and meshes with the worm gear 36. By rotating the worm 37, the entire heating shell 13, along with the fermentation shell 12 inside, can be tilted to facilitate subsequent material discharge. The upper end of the heating shell 13 is provided with a material pipe 34 with a sealing cap for feeding and observation.

[0026] 2. Detailed structure of the bidirectional mechanism 21 The bidirectional mechanism 21 is a component that directly performs the stirring function. Its design goal is to decompose the unidirectional rotation of the drive shaft into a composite motion in which the upper and lower stirring sleeves both revolve around each other and move towards / away from each other axially.

[0027] Core stirring components: On the inner wall of the fermentation shell 12, there are rotatable lower stirring sleeves 22 and upper stirring sleeves 23 spaced apart vertically. Both have multiple stirring blades 24 evenly spaced along the circumference on their inner walls for directly shearing and turning the organic matter.

[0028] Spatial linkage transmission system: This is the key to achieving axial movement. Two sets of outer ball sleeves 25 are fixed to the inner walls of both the lower stirring sleeve 22 and the upper stirring sleeve 23. Each outer ball sleeve 25 contains a freely rotatable ball 26.

[0029] Each of the upper-layer rolling balls 26 is connected to a downwardly extending side rod 27, the other end of which is also connected to an inner ball sleeve 28 via a rolling ball 26. All four inner ball sleeves 28 are fixedly installed on the outer end of a cross sleeve 211.

[0030] Each of the four rolling balls 26 located on the lower layer is connected to a side rod 27 extending diagonally upward. Similarly, the other end of the side rod 27 is connected to the inner ball sleeve 28 through the rolling balls 26. These four inner ball sleeves 28 are fixed to another cross sleeve 211.

[0031] Two cross sleeves 211 are coaxially arranged. Each side rod 27 is also equipped with a rotating blade 210 via a bearing sleeve. The rotating blade 210 is axially limited by two retaining rings 29 on the side rod 27, allowing it to rotate around the side rod 27 under fluid resistance, thereby enhancing local turbulence.

[0032] 3. Drive mechanism 31 The drive mechanism 31 provides the initial power. The motor 32 is fixedly mounted on the heating shell 13 or the bracket 35, and its output shaft is connected to the drive shaft 33. The drive shaft 33 extends downward, passes through the top center of the heating shell 13 and the fermentation shell 12, and passes through the center hole of the two cross sleeves 211, forming a rotatable connection with them via bearings. Therefore, when the motor 32 starts, it directly drives the rotation of the drive shaft 33.

[0033] 4. Unidirectional Mechanism 41 (Flexible Transmission and Motion Conversion Core) The one-way mechanism 41 is key to selectively and flexibly transmitting the unidirectional rotation of the drive shaft 33 to the upper and lower cross sleeves 211, and introducing axial movement in the process. It is mounted on the drive shaft 33 and located between the two cross sleeves 211.

[0034] Intermediate disk 42 and slant rod assembly: An intermediate disk 42, through multiple internal vertical bars 43, engages with a keyway on the drive shaft 33, achieving synchronous rotation but allowing axial sliding. On the disk body of the intermediate disk 42, several sets of inclined guide grooves are distributed circumferentially, divided into upper inclined grooves 44 and lower inclined grooves 45 (inclination angle, for example, 45 degrees). A slidable slant rod 46 is installed in each inclined groove, and a top spring 47 is provided at the tail of the slant rod 46, giving its head a tendency to spring outwards.

[0035] One-way clutch assembly: On each side of the intermediate disc 42, a one-way disc 48 is tightly fitted. Each one-way disc 48 has a one-way groove 49 on its end face that matches the shape of the head of the swashplate 46. The two one-way discs 48 are fixed together by a pair of clamps 410 that are bolted together.

[0036] Flexible Torque Connection: The aforementioned one-way steering wheel unit 48 is connected to the upper and lower cross sleeves 211 via an upper torsion spring 411 and a lower torsion spring 412, respectively. Specifically, a torsion spring (411 or 412) is connected to each of the two opposite sides of each cross sleeve 211, and the other end of the torsion spring is connected to the one-way steering wheel unit 48. The preload direction of all torsion springs (411, 412) is set to the same.

[0037] 5. Working process and principle of the device S1: Initial State and Power Transmission When the motor 32 is started, the drive shaft 33 begins to rotate. The drive shaft 33 drives the intermediate disk 42 to rotate synchronously via the vertical bar 43. When the intermediate disk 42 rotates, the head of the inclined rod 46 on it will abut against the one-way groove 49 of the one-way disk 48 on the side matching the rotation direction under the action of centrifugal force or inclined plane.

[0038] Assuming that the right-side (in the view direction) diagonal bar 46 is effectively engaged at this time, it will push the right-side one-way disc 48, which in turn will cause the entire one-way disc 48 unit to rotate through the clip 410.

[0039] This rotational torque is transmitted to the upper cross sleeve 211 via the upper torsion spring 411, and simultaneously to the lower cross sleeve 211 via the lower torsion spring 412. Due to the characteristics of the torsion spring, the torque is transmitted flexibly.

[0040] S2: Generation of bidirectional stirring motion When the upper and lower cross sleeves 211 begin to rotate under the pull of the torsion springs (411, 412), the spatial linkage system begins to work: For the upper cross sleeve 211: its rotation is achieved through four downward-sloping side rods 27, which pull the upper stirring sleeve 23. Since the side rods 27 are arranged at an angle, this pulling force can be decomposed into a circumferential component (driving the upper stirring sleeve 23 to rotate) and a downward axial component (driving the upper stirring sleeve 23 to move downward).

[0041] For the lower cross sleeve 211: its rotation is transmitted through four upward-sloping side rods 27, which in turn push the lower stirring sleeve 22. Similarly, this thrust can be decomposed into a circumferential component that drives the lower stirring sleeve 22 to rotate, and an upward axial component.

[0042] Therefore, during one phase of the unidirectional rotation of the drive shaft 33, the upper stirring sleeve 23 and the lower stirring sleeve 22 are simultaneously performing circumferential revolution stirring and axial movement that brings them closer together.

[0043] S3: Motion Reversal and Flexible Overload Protection When the motor 32 continues to run, or when the transmission phase changes due to material resistance, the diagonal rod 46 on the other side (left side) of the intermediate disk 42 will engage effectively with the one-way groove 49. At this time, the force direction of the one-way disk 48 unit changes relative to the cross sleeve 211.

[0044] The upper torsion spring 411 or lower torsion spring 412, which was originally under tension, may slacken, while the torsion spring on the other side begins to be stretched. This switching process is instantaneous, but due to the flexibility of the torsion spring, rigid impact is avoided.

[0045] The core functions of the torsion springs (411, 412) are "flexible connection" and "one-way energy storage". They allow the rotation of the cross sleeve 211 to lag slightly behind or lead the rotation of the one-way disc 48, thereby absorbing instantaneous load fluctuations caused by uneven material density and protecting the transmission system. At the same time, their energy storage and release characteristics make the movement trajectory of the stirring blade 24 not completely uniform, increasing the randomness and "kneading" effect of stirring, which is beneficial for breaking up agglomerates.

[0046] As the force-bearing side switches, the direction of the axial component force on the upper and lower cross sleeves 211 may also change, thereby driving the upper and lower stirring sleeves 22 and 23 to change from moving towards each other to moving away from each other, forming axial reciprocating stirring.

[0047] S4: Auxiliary mixing and discharging Throughout the process, the self-rotating blade 210 mounted on the side rod 27 will rotate on its own under the resistance of the material, generating additional local vortices and further enhancing micro-mixing.

[0048] Once fermentation is complete, stop motor 32. By rotating worm gear 37, drive worm wheel 36 to tilt the entire heating shell 13 and fermentation shell 12. At this point, motor 32 can be restarted (or reversed), and the fermentation product can be discharged from feed pipe 34 or bottom outlet using stirring blade 24.

[0049] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

The inclined rod (46) on the rotating intermediate disk (42) is inserted into the one-way groove (49) on the one-way disk (48) that matches its rotation direction under the action of centrifugal force and inclined plane, so as to realize the one-way transmission locking on this side. Second stage: Flexible torque transmission and motion decomposition. The rotational tendency of the locked one-way disc (48) is flexibly transmitted to the upper and lower cross sleeves (211) through the upper torsion spring (411) and the lower torsion spring (412). The rotation of each cross sleeve (211) is driven by multiple side rods (27) that are hinged to it and arranged in a spatial oblique direction, pushing the upper stirring sleeve (23) and the lower stirring sleeve (22). This process decomposes the pure rotational motion of the cross sleeve (211) into a composite motion in which the stirring sleeve both revolves around the axis and moves towards or away from each other along the axis. The third stage: multi-dimensional stirring and overload buffering. The upper and lower stirring sleeves (22) and the stirring blades (24) on them perform circumferential stirring while moving axially to achieve three-dimensional tumbling of organic matter. The flexible connection characteristics of the torsion spring can absorb the impact caused by sudden changes in material resistance and avoid damage to rigid transmission. At the same time, the self-rotating blades (210) on the side rod (27) rotate freely in the fluid to enhance local mixing. Fourth stage: motion reversal and material discharge preparation. When the transmission phase changes or the stirring direction needs to be changed, the inclined rod (46) on the other side of the middle plate (42) meshes with the corresponding one-way groove (49), the driving direction changes, and the stirring sleeve moves in the opposite axial direction. After fermentation, the worm gear (36) can be driven by the worm (37) to tilt the entire heating shell (13) and fermentation shell (12), and the material is discharged by the stirring blade (24).
