Description

Technical Field

[0001] The invention belongs to the field of soilless cultivation of garden seedlings, in particular to a soilless seedling cultivation device for garden greening plants. Background Art

[0002] Soilless seedling cultivation for landscaping plants refers to a seedling cultivation technology that does not rely on natural soil, but uses artificially prepared nutrient solution or inert matrix to provide plants with water, nutrients and a fixed root environment to meet the growth and development needs of seedlings. In landscaping, matrix soilless seedling cultivation is mainly suitable for plants with strong root support, which should not be soaked for a long time or have high requirements for air permeability, such as roses, photinia, pansies, etc. It has significant advantages, especially in areas with poor soil conditions, space-constrained scenes and in the cultivation of rare varieties. It can accurately control the growth environment and improve the survival rate and seedling efficiency.

[0003] Existing soilless seedling cultivation technologies typically include core components such as seedling containers, plant anchoring components, nutrient solution circulation systems, and environmental control devices. These systems achieve automated or semi-automated control of the seedling environment, improving standardization and survival rates. However, the substrate is prone to compaction during use, particularly due to factors such as irrigation, evaporation, and root secretions. This reduces the substrate's porosity, impairing air permeability and water permeability, severely impacting seedling growth.

[0004] Currently, common methods for treating substrate compaction include ultrasonic disruption and drill pipe crushing. Ultrasonic technology uses high-frequency vibrations to break up compaction, but it can easily cause mechanical damage to seedling roots and potentially destabilize the substrate structure. This technology also suffers from high energy consumption, complex equipment, and is not suitable for large-scale application. Traditional drill pipe cleaning methods apply roughly equal cleaning force to the upper and lower layers of the substrate. In practice, however, materials in the substrate settle under the influence of gravity. For example, coarse particles like vermiculite and perlite float upward, while fine particles like organic matter sink, significantly increasing the density at the bottom. During irrigation periods, water carries particles downward. During evaporation periods, capillary action at the bottom accumulates salts and colloids. The main root zone of the seedlings absorbs water rapidly, forming localized dry zones. Root hairs secrete mucus that accelerates particle adhesion. These factors often lead to more severe compaction in the middle and lower layers of the substrate (deeper layers). Traditional drill pipe cleaning methods cannot specifically break up compaction in both layers without damaging the root system.

[0005] To this end, the present invention provides a soilless seedling raising device for garden greening plants. Summary of the Invention

DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0035] Example 1

[0036] like Figure 1-7 As shown, a soilless seedling raising device for landscaping plants according to an embodiment of the present invention comprises:

[0037] A container 1, wherein the container 1 is filled with a substrate for cultivating seedlings;

[0038] A plurality of support mechanisms 2 are distributed outside the container 1, and the support mechanism 2 includes a bracket 21, a support 22 is movably provided on the top of the bracket 21, and a lifting seat 23 is slidably provided on the support 22;

[0039] A loosening mechanism 3 for loosening the matrix, the loosening mechanism 3 comprising: a loosening member 31 movably arranged on the support 22 , a drill bit 311 being fixedly connected to the bottom end of the loosening member 31 ;

[0040] The oscillation mechanism 4 oscillates the substrate, and the oscillation mechanism 4 includes an oscillation gear 41 rotatably arranged on the lifting seat 23. An ear seat 42 is movably provided in the support 22. The ear seat 42 is sleeved on the outside of the loosening part 31. The eccentric part of the oscillation gear 41 is movably hinged to the ear seat 42 through a connecting rod 43. After the oscillation gear 41 rotates, the loosening part 31 is driven to swing horizontally through the connecting rod 43.

[0041] Specifically, when using a substrate for soilless cultivation of garden greening plants such as roses, photinia, and pansies, first select a container 1 of appropriate size according to the specific type of greening plant and place it in a cultivation environment such as a seedling shed. Fill the container 1 with a substrate, which can be a mixed substrate of peat and perlite. Plant seedlings or seeds are planted in the substrate. During the cultivation process, nutrient solution is added as needed. Depending on the situation, a plant fixing component can also be used to fix the seedlings.

[0042] The bracket 21 is placed on the outside of the container 1, and the support 22 can move up and down and horizontally relative to the bracket 21. Initially, the support 22 and the structure inside the support 22 are located on the outside of the container 1 to avoid hindering the growth of plants in the container 1. When the substrate becomes compacted and needs to be broken and cleaned, the support 22 is moved to the inside of the container 1 so that the loosening part 31 is located above the substrate and is in a vertical state. Then, the loosening part 31 is started to rotate and move downward.

[0043] After the loosening member 31 rotates and moves downward, the drill bit 311 is inserted into the substrate to initially loosen the substrate to eliminate the problem of compaction. The rotational insertion method can destroy the deep compaction structure and loosen the upper substrate, reducing the resistance during subsequent vibration. The scope of initial loosening is limited to 5 cm outside the periphery of the plant stem to avoid touching the plant root system. Since the root growth of the plant is not completely controllable, some plant roots may be too long and extend below the loosening member 31. The drill bit 311 is made of a stainless steel core and a silicone outer layer. The silicone is 2 mm thick to avoid possible root damage caused by hard contact between the drill bit 311 and the plant root system.

[0044] When the loosening part 31 moves down to the bottom, the oscillation gear 41 is started to rotate. The oscillation gear 41 drives the ear seat 42 to swing horizontally through the connecting rod 43, and the ear seat 42 drives the loosening part 31 to swing, causing a small amplitude oscillation on the surrounding matrix. The parameters of the small amplitude oscillation are preferably but not limited to a frequency of 2-5Hz and an amplitude of 10-30mm. The vibration wave is transmitted through the matrix, and the non-Newtonian fluid effect is used to separate the compacted particles, thereby achieving secondary loosening of the compacted matrix near the root system.

[0045] As another embodiment, the bracket 21 and the support 22 may be evenly distributed in a circular manner on the outside of the container 1 , or an annular bracket 21 may be provided on the outside of the container 1 , and a plurality of supports 22 may be evenly distributed in a circular manner on the bracket 21 .

[0046] As another embodiment, when starting, the loosening member 31 is inserted into the matrix in a low-speed spiral manner, and the bracket 21 or the support 22 can be moved around the container 1, so that the loosening member 31 moves in a circular motion in the matrix, forming an annular loosening belt, thereby expanding the range of breaking the compacted matrix.

[0047] Through this setting, the device of the present application solves the problem of matrix compaction when working, and also has a root protection mechanism: maintaining a safe distance can avoid direct mechanical damage, and low-frequency vibration is less likely to cause root cell wall rupture than high-frequency vibration.

[0048] It should be noted that the movement of the support 22 can be controlled by manual operation or an electric push rod; a spiral groove can be provided on the outside of the drill bit 311 to make it easier for the drill bit 311 to drill into the hardened matrix; by placing different restrictions on the movement range of the ear seat 42 in the lifting seat 23, the ear seat 42 can swing in different ways, so that the final lateral swing of the loose part 31 can be either a left-right reciprocating swing or a circumferential swing.

[0049] like Figure 3-5 As shown, it also includes a guide positioning mechanism 5, and the guide positioning mechanism 5 includes:

[0050] A guide 51 is fixed to the support 22, and the loosening member 31 passes through the guide 51, and the loosening member 31 is radially guided by the guide 51;

[0051] A sliding block 52 is slidably arranged in the guide 51, and the bottom end of the guide 51 is provided with a step for limiting the sliding block 52;

[0052] A spherical joint 53 is arranged at the top end of the loosening member 31 and is in spherical connection with the sliding block 52, and the top end of the loosening member 31 is provided with a tapered slope for guiding.

[0053] Specifically, the guide 51 can adopt a bearing structure, or a roller shaft is arranged on the inner wall of the guide 51 to reduce the friction between the guide 51 and the loosening member 31; the guide 51 is located above the loosening member 31, the loosening member 31 is in a round rod shape, the inner portion of the guide 51 is provided with a circular groove corresponding to the loosening member 31, the sliding block 52 can move up and down in the guide 51 and will not fall off from the guide 51, and the sliding block 52 is always in spherical connection with the spherical joint 53; initially, the loosening member 31 is located at the upper end in the guide 51, when the matrix is preliminarily loosened, the loosening member 31 rotates and moves downward in the guide 51, when the sliding block 52 moves to the lowest end in the guide 51, the loosening member 31 also moves to the lowest end, at this time, the loosening member 31 is vibrated, and in the vibration process, the top end of the loosening member 31 is suspended in the sliding block 52 through the spherical joint 53, so that the loosening member 31 is prevented from falling off and the amplitude is prevented from being too large, and the stability of the vibration work is improved.

[0054] As shown in Figure 2-7 , the device further comprises a driving mechanism 6, and the driving mechanism 6 comprises:

[0055] A motor 61 is arranged on the support 22;

[0056] A driving gear 62 is fixed to the output shaft of the motor 61;

[0057] A rotating gear 63 is rotatably arranged on the lifting seat 23, and the rotating gear 63 is sleeved on the outer side of the loosening member 31;

[0058] A spline 64 is arranged on the side wall of the loosening member 31, and the rotating gear 63 is slidably connected with the loosening member 31 through the spline 64;

[0059] A sleeve 65 is fixed to the support 22, and the sleeve 65 is sleeved on the outer side of the loosening member 31, and the sleeve 65 is used to vertically move when the drill rod rotates.

[0060] Specifically, the height position of the rotating gear 63 is unchanged, the inner wall of the rotating gear 63 is provided with a through groove 64, allowing the loose part 31 to slide axially; the outer side of the loose part 31 is provided with an external thread, and the inner wall of the sleeve 65 is processed with an internal thread matched with the loose part 31. It should be noted that other structures that can meet the up-and-down movement of the loose part 31 during reciprocating rotation are also applicable to the manufacture of the sleeve 65; the rotating gear 63 is located below the oscillating gear 41, and after the lifting seat 23 moves up and down, one of the rotating gear 63 and the oscillating gear 41 is engaged with the driving gear 62.

[0061] Initially, the lifting seat 23 is located at the top end of its moving range, and the driving gear 62 is in contact with the rotating gear 63; when cleaning the matrix crust, the driving gear 62 is driven to rotate by the motor 61, and the rotating gear 63 is driven to rotate by the driving gear 62. The loose part 31 moves downward during rotation, thereby inserting into the matrix.

[0062] When performing oscillation cleaning, the lifting seat 23 is moved downward, so that the rotating gear 63 is separated from the driving gear 62 and the oscillating gear 41 is in contact with the driving gear 62. At this time, the motor 61 drives the oscillating gear 41 to rotate through the driving gear 62, thereby driving the loose part 31 to oscillate and clean the matrix. By moving the position of the lifting seat 23, the loose part 31 can be switched between rotating insertion and oscillation.

[0063] As another embodiment, by selecting and setting the transmission ratio of the rotating gear 63, the oscillating gear 41 and the driving gear 62, the motor 61 can be rotated at a constant speed, the rotating gear 63 can be rotated at a low speed when it is in contact with the driving gear 62, so that the loose part 31 can be rotated into the matrix at a low speed, and the oscillating gear 41 can be rotated at a high speed when it is in contact with the driving gear 62, so that the oscillation frequency and intensity of the loose part 31 on the matrix are improved.

[0064] As shown in Figure 2-8 , the driving mechanism 6 further comprises:

[0065] A push plate 66 provided on the driving gear 62, the push plate 66 being ramp-shaped;

[0066] Two driven plates 67 movably provided on the lifting seat 23, the driven plates 67 being ratchet structures, the rotation directions of the two driven plates 67 being opposite, and the lifting seat 23 being driven to move up and down by the cooperation of the push plate 66 and the driven plate 67 during the forward and reverse rotation of the motor 61.

[0067] Specifically, enough space is left between the two driven plates 67, and one of the driven plates 67 will not touch the other driven plate 67 after rotation. One of the driven plates 67 is provided with a notch matched with the driven plate 67. During the forward rotation of the driving gear 62, the push plate 66 drives the lifting seat 23 to move downward by matching with one of the driven plates 67. During the reverse rotation of the driving gear 62, the push plate 66 drives the lifting seat 23 to move upward by matching with the other driven plate 67.

[0068] As shown in Figure 6-8 , the support mechanism 2 further comprises:

[0069] The telescopic rod 24 is obliquely arranged, and two ends of the telescopic rod 24 are movably connected with the bracket 21 and the lifting seat 23, respectively.

[0070] The extension spring 25 is arranged to push the telescopic rod 24 to expand.

[0071] Specifically, in Figure 6 , initially, when the lifting seat 23 is located at the upper position, the telescopic rod 24 is in an oblique state of left low and right high. After the lifting seat 23 moves downward, the telescopic rod 24 is in an oblique state of left high and right low. The telescopic rod 24 is kept in an expanded state of elongation under the pushing of the extension spring 25, so that the lifting seat 23 keeps stable after moving upward or downward. Thus, the stability of the contact between the rotating gear 63 or the oscillating gear 41 and the driving gear 62 is improved.

[0072] As shown in Figure 3-5 , the loosening member 31 is provided with a first groove 312 and a second groove 313. After the loosening member 31 moves downward, the first groove 312 is located inside the sleeve 65, and the second groove 313 is located inside the rotating gear 63.

[0073] Specifically, initially, the first groove 312 is located above the sleeve 65, the second groove 313 is located above the rotating gear 63, and the main rod part of the loosening member 31 contacts the sleeve 65 and the rotating gear 63, so as to ensure that the loosening member 31 can stably rotate and move downward. When the substrate is shaken and cleaned, the loosening member 31 moves downward. At this time, the first groove 312 is located inside the sleeve 65, and the second groove 313 is located inside the rotating gear 63. Gaps appear between the loosening member 31 and the sleeve 65 and the rotating gear 63, and spaces are left for the loosening member 31 in the horizontal direction, so that the loosening member 31 can perform oscillation.

[0074] As shown in Figure 5 , the spline 64 comprises a wide edge section and a narrow edge section, and the narrow edge section is located in the second groove 313. The wide edge section and the narrow edge section are smoothly connected. The inner wall of the rotating gear 63 is provided with a through groove matched with the wide edge section. After the loosening member 31 moves downward, the narrow edge section and the inner wall of the rotating gear 63 leave a gap for the loosening member 31 to swing.

[0075] Specifically, the width of the narrow side section is smaller than the width of the wide side section. According to requirements, the thickness of the narrow side section can also be designed to be smaller than the thickness of the wide side section. A transition slope is provided between the narrow side section and the wide side section, so that after the loose part 31 moves up, the wide side section can be smoothly inserted into the through groove.

[0076] Initially, the wide side section cooperates with the through groove of the rotating gear 63, constraining the loose part 31 to move only up and down, ensuring that the rotating gear 63 drives the loose part 31 to rotate downward stably; during vibration cleaning, after the loose part 31 moves downward, the narrow side section moves downward to be aligned with the through groove of the rotating gear 63, leaving a gap between the second groove 313 and the narrow side section and the inner wall of the rotating gear 63.

[0077] Example 2

[0078] like Figure 3-5 As shown in Comparative Example 1, another embodiment of the present invention is:

[0079] The loosening mechanism 3 also includes:

[0080] a cavity 32 provided inside the loose member 31;

[0081] A mass block 33 is slidably disposed in the cavity 32 .

[0082] During soilless seedling cultivation, the deeper layers of the substrate are often more compacted. Because the upper and lower layers of the substrate have different degrees of compaction, different levels of breaking up the compaction are required. Traditional methods, such as crushing or oscillating devices, do not distinguish between the upper and lower layers, and the breaking force of the upper and lower layers is generally the same. Using too high a breaking force can lead to waste, while using too low a breaking force can easily result in incomplete removal of the deep layers. This issue needs to be improved.

[0083] Specifically, according to actual needs, a buffer pad can be set on the bottom wall of the cavity 32, and the mass block 33 can move up and down inside the cavity 32 to form a built-in impact generator. After the mass block 33 slides to the bottom inside the loose part 31, according to the energy focusing effect, the center of gravity moves downward, and the vibration energy is concentrated in the deep layer. The mass block 33 hits the buffer pad, and the shock wave is transmitted to the matrix below the loose part 31. By setting the mass block 33 inside the loose part 31, the deep energy transmission is enhanced, the vibration energy is concentrated in the deep layer, and the targeted breaking of the deep-layer compacted matrix is ​​achieved.

[0084] During use, the device of the present application can target the deep matrix with higher force to break up the hardening degree of the upper and lower parts of the matrix, without the need to adjust the power of the entire device. Not only is the breaking effect better, but it is also more convenient to use.

[0085] like Figure 3-5 As shown, the mass block 33 and the loosening member 31 are both made of non-magnetic materials, and the loosening mechanism 3 further includes:

[0086] A magnetic conductive member 34 fixedly connected to the loose member 31;

[0087] A magnet 1 35 is fixedly connected to the top of the mass block 33, and the mass block 33 is adsorbed on the bottom of the magnetic conductive member 34 through the magnet 1 35;

[0088] A second magnet 36 is fixed to the bottom end of the lifting base 23. When the lifting base 23 moves downward, the second magnet 36 contacts the magnetic conductive member 34. The magnetic conductive member 34 is magnetized by the second magnet 36 and repels the first magnet 35, pushing the mass block 33 downward.

[0089] An isolation block 37 is provided inside the cavity 32 , and the isolation block 37 is blocked between the magnet 1 35 and the magnetic conductive member 34 .

[0090] Specifically, to improve longitudinal impact resistance, mass block 33 is constructed from a material with a higher density than the magnet. For example, mass block 33 is preferably constructed from a tungsten-nickel-iron alloy. This alloy has a density close to that of pure tungsten, but significantly improved toughness. Adjusting the nickel-iron ratio optimizes strength, plasticity, and workability, providing impact and corrosion resistance and suitability for use in oscillating environments. Of course, for convenience, mass block 33 and magnet 1 35 can also be configured as a single, integrated magnetic structure.

[0091] Magnet 1 35 does not directly contact magnetic member 34. The thickness of isolation block 37 is designed to minimize the magnetizing effect of magnet 1 35 on magnetic member 34 while ensuring that mass 33 is adsorbed beneath magnetic member 34. This ensures that magnet 2 36 can successfully magnetize magnetic member 34 upon contact. During the oscillation phase, when loose member 31 swings laterally, magnetic member 34 is magnetized upon contact with magnet 2 36. This magnetization results in the same magnetic properties on the opposing sides of magnetic member 34 and magnet 1 35, leading to repulsion between like-charged magnets and pushing mass 33 downward.

[0092] like Figure 3-5 As shown, the second magnet 36 is detachably connected to the lifting seat 23 , and a slope is provided at the bottom of the second magnet 36 . After the lifting seat 23 moves downward and the loosening member 31 swings, the magnetic conductive member 34 intermittently contacts the second magnet 36 .

[0093] Specifically, since the lifting seat 23 can only move up and down but not laterally, during the continuous lateral swing of the loosening part 31, the magnetic part 34 intermittently contacts the magnet 2 36, and the magnetic part 34 is intermittently magnetized. Under the action of the magnet 1 35, the mass block 33 is driven to move back and forth up and down, thereby realizing continuous targeted breaking of the deep-layer compacted matrix and improving the breaking effect.

[0094] As a further embodiment, a reset plate 231 can be arranged at the bottom end of the lifting seat 23, and the bottom of the reset plate 231 and the magnet 36 are both provided with a slope for pushing the magnet 36 back to the middle position. After the lifting seat 23 is lowered, the reset plate 231 and the magnet 36 are respectively located on both sides of the magnetic conductor 34, and the distance between the reset plate 231 and the magnet 36 is greater than the outer diameter of the magnetic conductor 34. When the loosening part 31 swings laterally, after the consolidation cleaning is completed, the position of the loosening part 31 can not be directly below the lifting seat 23, and can be left or right. In order to ensure that the magnet 36 can be smoothly lowered to contact the magnetic conductor 34 after the lifting seat 23 is lowered next time, the reset plate 231 with a slope at the bottom and the magnet 36 are arranged, and the slope plays a guiding role and can adjust the position of the magnetic conductor 34 with lateral position deviation.

[0095] Working principle: when the substrate of the landscaping plant is used for soilless cultivation, first, according to the specific type of the landscaping plant, a container 1 with a suitable size is selected and placed in a seedling raising shed or other cultivation environment, the container 1 is filled with substrate, the substrate can be a mixed substrate of peat and perlite, and the plant seedling or seed is planted in the substrate. During the cultivation process, nutrient solution is added as needed.

[0096] Initially, the driving gear 62 is in contact with the rotating gear 63, and the loosening part 31 is located at the top end of its moving range. When the substrate is consolidated during the cultivation process and needs to be broken, the support 22 is moved to the inside of the container 1, so that the loosening part 31 is located above the substrate and in a vertical state. Then, the motor 61 is started in forward rotation, and the forward rotation direction is indicated by the arrow direction in Figure 8 , the driving gear 62 on the motor 61 drives the rotating gear 63 to rotate at low speed, and under the cooperation of the sleeve 65, the loosening part 31 rotates and moves downward at the same time, thereby rotating and inserting into the substrate to preliminarily break the substrate;

[0097] During the forward rotation of the driving gear 62, the push plate 66 cooperates with the right side driven plate 67 with a notch in Figure 8 to push the lifting seat 23 to move downward. It should be noted that in order to prolong the downward movement stroke of the loosening part 31, a speed regulating gear can be arranged between the driving gear 62 and the rotating gear 63, and the push plate 66 is installed on the speed regulating gear. After the driving gear 62 rotates for multiple turns, the loosening part 31 moves downward to a deeper position, and then the push plate 66 contacts the right side driven plate 67 and drives the lifting seat 23 to move downward;

[0098] After the lifting seat 23 moves down, the rotating gear 63 and the vibrating gear move down synchronously, so that the rotating gear 63 is separated from the driving gear 62 and the oscillating gear 41 is in contact with the driving gear 62. At this time, the motor 61 drives the oscillating gear 41 to rotate through the driving gear 62, thereby driving the loosening member 31 to swing, vibrating the substrate, and breaking the hardened substrate in the deep layer. In addition, the vibration can be transmitted horizontally to achieve secondary loosening of the hardened substrate near the root system.

[0099] During the oscillation stage, the loose part 31 is in continuous lateral swinging process, and the magnetic part 34 is intermittently in contact with the second magnet 36. The magnetic part 34 is intermittently magnetized, and under the action of the first magnet 35, it drives the mass block 33 to move up and down, thereby realizing continuous targeted breaking of the deep-layer compacted matrix and further improving the breaking effect.

[0100] After the work of breaking the hardened matrix is ​​completed, the motor 61 is started to reverse. During the reverse rotation of the motor 61, the dial plate 66 cooperates with the driven plate 67 on the left to push the lifting seat 23 to move up and reset. After the lifting seat 23 moves up, the oscillation gear 41 is separated from the driving gear 62 and the rotating gear 63 contacts the driving gear 62. The rotating gear 63 rotates and drives the loosening member 31 to rotate and move up until it returns to its initial state. In this way, during use, the present device can control the forward and reverse rotation of the motor 61 to achieve the initial breaking of the hardened matrix by the rotation and insertion of the loosening member 31, the secondary breaking of the loosening member 31 by the transverse oscillation, and the deep targeted breaking of the mass block 33 by the longitudinal movement. At the same time, it can automatically reset, achieving targeted breaking of the upper and lower layers of the matrix and improving the breaking effect. Moreover, only one motor 61 needs to be controlled to complete the above work. Compared with the traditional method of setting multiple groups of electric drive systems, the structure is greatly simplified and it is more convenient to use and maintain.
