Technical Field

[0001] This application relates to the technical field of soilless cultivation, and in particular to a soilless cultivation device for agricultural use. Background Technology

[0002] Currently, soilless cultivation, simply put, means growing plants without natural soil, using nutrient solutions or solid substrates plus nutrient solutions. The core is to bypass the soil and directly provide the roots with "water, fertilizer, air, and support".

[0003] Existing soilless cultivation devices for agriculture generally include a cultivation rack, multiple cultivation tubes installed on the top of the cultivation rack, a top plate installed on the top of the cultivation rack, a lamp holder installed at the bottom of the top plate, and multiple lamp bodies installed at the bottom of the lamp holder.

[0004] Different growth stages of plants, such as the seedling stage, vegetative growth stage, and flowering and fruiting stage, have different requirements for light intensity. The distance between the lamp body and the plant is one of the factors that affects the light intensity. However, current technology makes it inconvenient to adjust the distance between the lamp body and the plant. Summary of the Invention

[0005] To facilitate adjustment of the distance between the lamp body and the plant, this application provides a soilless cultivation device for agriculture, employing the following technical solution:

[0006] A soilless cultivation device for agriculture includes a cultivation rack, multiple cultivation tubes installed on the top of the cultivation rack, a top plate installed on the top of the cultivation rack, a lamp holder installed on the bottom of the top plate, and multiple lamp bodies installed on the bottom of the lamp holder. A drive mechanism for moving the lamp holder is installed on the bottom of the top plate. The drive mechanism includes a drive motor installed on the bottom of the top plate, a lead screw installed on the output shaft of the drive motor, and a guide rod installed on the bottom of the top plate. The lamp holder is threaded to the lead screw and slidably connected to the guide rod.

[0007] By adopting the above technical solution, when it is necessary to adjust the distance between the lamp body and the plant, the drive motor is started first. At this time, the output shaft of the drive motor drives the lead screw, the lead screw rotates and drives the lamp holder to move. The movement of the lamp holder can adjust the distance between the lamp body and the plant. In summary, the drive mechanism is designed to facilitate the adjustment of the distance between the lamp body and the plant.

[0008] Optionally, two sets of reflective mechanisms are installed at the bottom of the top plate.

[0009] By adopting the above technical solution and setting up a reflective mechanism, it is easy to reflect the light emitted by the lamp body onto the plants, which can improve the light efficiency of the lamp body.

[0010] Optionally, each set of the reflective mechanism includes a rotating groove formed at the bottom of the top plate, a first rotating shaft rotatably connected to the inner wall of the rotating groove, a connecting plate sleeved and fixed to the side wall of the first rotating shaft, and a reflective plate fixed to the bottom of the connecting plate; the reflective mechanism also includes a drive assembly for driving the first rotating shaft to rotate.

[0011] By adopting the above technical solution, the reflector facilitates light reflection, and the drive assembly facilitates the rotation of the first shaft, thereby facilitating the adjustment of the reflector's angle. After adjusting the distance between the lamp body and the plant, according to the principle of reflection, when the lamp body is closest to the plant, it provides direct light; therefore, a V-shaped arrangement of the two reflectors facilitates illumination of the plant's roots. When the lamp body is furthest from the plant, the light diffuses; therefore, a V-shaped arrangement of the two reflectors helps to collect the diffused light, thus facilitating plant illumination. When the distance between the lamp body and the plant is moderate, a V-shaped arrangement of the two reflectors facilitates plant illumination. In summary, the reflective mechanism further improves light efficiency.

[0012] Optionally, the drive assembly includes a vertical groove formed at the bottom of the top plate, a vertical tube rotatably connected to the inner wall of the vertical groove, and a vertical rod disposed within the vertical tube; the bottom of the vertical rod is fixedly connected to the top of the lamp holder, and multiple spiral blocks are installed on the side wall of the vertical rod; multiple spiral grooves are formed on the inner wall of the vertical tube, and the spiral blocks and spiral grooves correspond to each other; a second rotating shaft is rotatably connected to the side wall of the vertical groove, a first bevel gear is sleeved and fixedly mounted on the outer wall of the vertical tube, a second bevel gear is installed at one end of the first rotating shaft near the second rotating shaft, and a third bevel gear and a fourth bevel gear are fixedly connected to both ends of the second rotating shaft, the first bevel gear meshes with the third bevel gear, and the second bevel gear meshes with the fourth bevel gear.

[0013] By adopting the above technical solution, the movement of the lamp holder drives the vertical rod to move. At this time, the vertical rod drives the vertical tube to rotate under the action of the spiral block and spiral groove. The rotation of the vertical tube drives the first bevel gear to rotate, the rotation of the first bevel gear drives the third bevel gear to rotate, the rotation of the third bevel gear drives the second rotating shaft to rotate, the rotation of the second rotating shaft drives the fourth bevel gear to rotate, the rotation of the fourth bevel gear drives the second bevel gear to rotate, the rotation of the second bevel gear drives the first rotating shaft to rotate, the rotation of the first rotating shaft drives the connecting plate to rotate, and the rotation of the connecting plate drives the reflector to rotate. In summary, when it is necessary to adjust the height of the lamp holder, under the action of the drive assembly, the two reflectors can make adaptive angle adjustments according to the reflection principle. That is, when the lamp holder moves downward, the two reflectors rotate inward, and when the lamp holder moves upward, the two reflectors rotate outward.

[0014] Optionally, a cleaning mechanism for cleaning the inside of the reflector is installed in the rotating slot.

[0015] By adopting the above technical solution and setting up a cleaning mechanism, it is easy to clean the front of the reflector, which can reduce the impact of dust on the reflector's reflection.

[0016] Optionally, the cleaning mechanism includes a first slide groove formed on the top wall of the rotating groove, a first movable plate slidably connected to the inner wall of the first slide groove, a first reset assembly installed on the inner wall of the first slide groove for resetting the first movable plate, a second slide groove formed at the end of the first slide groove away from the rotating groove, a second movable plate slidably connected to the inner wall of the second slide groove, a second reset assembly installed on the inner wall of the second slide groove for resetting the second movable plate, a third slide groove formed at the end of the second slide groove away from the first slide groove, a third movable plate slidably connected to the inner wall of the third slide groove, and multiple sets of third reset assemblies installed on the inner wall of the third slide groove for resetting the third movable plate; A receiving rod is fixed to the bottom of the first movable plate, and the back of the reflector can drive the receiving rod to move; the first movable plate and the second movable plate are respectively provided with a first inclined surface on their respective inner sides, and the two first inclined surfaces match each other; the second movable plate and the third movable plate are respectively provided with a second inclined surface on their respective inner sides, and the two second inclined surfaces match each other; the bottom of the third sliding groove is provided through the bottom of the top plate, an air pump is installed inside the third movable plate, an air blowing pipe is provided at the bottom of the third movable plate, the air outlet of the air pump is connected to the top of the air blowing pipe, and the end of the air blowing pipe away from the air pump is inclined towards the front of the reflector.

[0017] By adopting the above technical solution, when the reflector rotates outward to a near-horizontal state, the reflector drives the receiving rod to move upward. The upward movement of the receiving rod drives the first moving plate to move upward. Then, under the action of the first inclined plane, the first moving plate drives the second moving plate to move. Next, under the action of the second inclined plane, the second moving plate drives the third moving plate to move downward. The downward movement of the third moving plate drives the air blowing pipe to move downward. This allows the bottom of the air blowing pipe to be aligned with the front of the reflector, thus facilitating the cleaning of the reflector's surface. In summary, the cleaning mechanism facilitates the cleaning of the reflector's surface.

[0018] Optionally, the first reset assembly includes a first reset groove formed in the inner wall of the first slide groove, a first reset block slidably connected to the inner wall of the first reset groove, and a first reset spring fixed to one side of the first reset block; the first reset block is fixed to the side wall of the first moving plate, and the end of the first reset spring away from the first reset block is fixed to the inner wall of one end of the first reset groove.

[0019] By adopting the above technical solution, the first moving plate moves upward, causing the first reset block to move upward, and the first reset block moves upward to press against the first reset spring; when the back of the reflector separates from the receiving rod, the first reset block drives the first moving plate to reset under the action of the first reset spring; in summary, the first reset component facilitates the reset of the first moving plate.

[0025] By adopting the above technical solution, when the air blowing pipe moves downward, it drives the sealing plate to rotate downward, which facilitates the air blowing pipe to clean the front of the reflector. When the air blowing pipe is reset, the third rotating shaft is reset under the action of the torsion spring, and the reset of the third rotating shaft drives the sealing plate to reset. In summary, the sealing mechanism is designed to facilitate the sealing of the bottom of the third slide groove.

[0034] The embodiments of this application are described in detail below, and examples of the embodiments are shown in the accompanying drawings.

[0035] In the description of this specification, the references to "certain embodiments," "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples" refer to specific features, structures, materials, or characteristics described in connection with the described embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0036] This application discloses an agricultural soilless cultivation device, referring to... Figure 1 and Figure 2 The system includes a culture rack 1, multiple culture tubes 11 mounted on the top of the culture rack 1, a top plate 2 mounted on the top of the culture rack 1 via a column 12, a lamp holder 21 mounted on the bottom of the top plate 2, and multiple lamp bodies 22 mounted on the bottom of the lamp holder 21. A drive mechanism 3 for moving the lamp holder 21 is mounted on the bottom of the top plate 2. A motor slot 23 is provided on the bottom of the top plate 2. The drive mechanism 3 includes a drive motor 31 vertically mounted in the motor slot 23, a lead screw 32 vertically mounted on the output shaft of the drive motor 31, and a guide rod 33 vertically mounted on the bottom of the top plate 2. The lamp holder 21 is threaded to the lead screw 32, and the guide rod 33 passes through the lamp holder 21. The lamp holder 21 slides vertically and is connected to the guide rod 33. The drive motor 31 is controlled by a controller, which can be a PLC. When it is necessary to adjust the distance between the lamp body 22 and the plant, the drive motor 31 is started first. At this time, the output shaft of the drive motor 31 drives the lead screw 32. The lead screw 32 rotates and drives the lamp holder 21 to move. The movement of the lamp holder 21 can adjust the distance between the lamp body 22 and the plant. In summary, the drive mechanism 3 is set to facilitate the adjustment of the distance between the lamp body 22 and the plant.

[0037] Reference Figure 2 and Figure 3 Two sets of reflective mechanisms 4 are installed at the bottom of the top plate 2; the reflective mechanisms 4 are designed to reflect the light emitted by the lamp body 22 onto the plants, thereby improving the light efficiency of the lamp body 22.

[0038] Reference Figure 2 and Figure 3Each reflector mechanism 4 includes a rotating groove 41 at the bottom of the top plate 2, a first rotating shaft 42 horizontally rotatably connected to the inner wall of the rotating groove 41 via a bearing, a connecting plate 43 sleeved and fixed to the side wall of the first rotating shaft 42, and a reflector 44 fixed to the bottom of the connecting plate 43. The reflector mechanism 4 also includes a drive assembly 5 for driving the first rotating shaft 42 to rotate. The rotation of the column 12 and the reflector 44 does not interfere with each other, that is, the column 12 does not affect the rotation of the reflector 44. The reflector 44 is designed to reflect light, and the drive assembly 5 is designed to drive the first rotating shaft 42 to rotate, thereby facilitating the adjustment of the angle of the reflector 44. When the distance between the lamp body 22 and the plant is adjusted, according to the principle of reflection, when the lamp body 22 is closest to the plant, the lamp body 22 provides direct light to the plant, so the two reflectors 44 are V-shaped (inward). Figure 1 When the lamp body 22 is at its furthest distance from the plant, the light will diffuse. Therefore, if the two reflectors 44 are arranged in an outward V-shape, it is easier to collect the diffused light and thus better illuminate the plant. When the lamp body 22 is at a centered distance from the plant, if the two reflectors 44 are arranged in a V-shape, it is easier to illuminate the plant. In summary, the reflector mechanism 4 is designed to further improve the light efficiency.

[0039] Reference Figures 2-4The drive assembly 5 includes a vertical groove 51 formed at the bottom of the top plate 2, a vertical tube 52 vertically rotatably connected to the inner wall of the vertical groove 51 via bearings, and a vertical rod 53 vertically arranged inside the vertical tube 52. The bottom of the vertical rod 53 is fixed to the top of the lamp holder 21. Multiple spiral blocks 531 are installed on the side wall of the vertical rod 53. Multiple spiral grooves 521 are formed on the inner wall of the vertical tube 52. The spiral blocks 531 and spiral grooves 521 are matched one-to-one. A second rotating shaft 54 ​​is horizontally rotatably connected to the side wall of the vertical groove 51 via bearings. A first rotating shaft 42 is perpendicular to the second rotating shaft 54. A first bevel gear 55 is fixedly fitted on the outer wall of the vertical tube 52. A second bevel gear 56 is installed at one end of the first rotating shaft 42 near the second rotating shaft 54. A third bevel gear 57 and a fourth bevel gear 58 are fixedly connected to both ends of the second rotating shaft 54, respectively. The first bevel gear 55 meshes with the third bevel gear 57, and the second bevel gear 56 meshes with the fourth bevel gear 58. The movement of the lamp holder 21 causes the vertical rod 53 to move. At this time, the vertical rod 53 drives the vertical tube 52 to rotate under the action of the spiral block 531 and the spiral groove 521. The rotation of the vertical tube 52 drives the first bevel gear 55 to rotate. The rotation of the first bevel gear 55 drives the third bevel gear 57 to rotate. The rotation of the third bevel gear 57 drives the second rotating shaft 54 ​​to rotate. The rotation of the second rotating shaft 54 ​​drives the fourth bevel gear 58 to rotate. The rotation of the fourth bevel gear 58 drives the second bevel gear 56 to rotate. The rotation of the second bevel gear 56 drives the first rotating shaft 42 to rotate. The rotation of the first rotating shaft 42 drives the connecting plate 43 to rotate. The rotation of the connecting plate 43 drives the reflector 44 to rotate. In summary, when it is necessary to adjust the height of the lamp holder 21, under the action of the drive assembly 5, the two reflectors 44 can adjust their angles according to the reflection principle. That is, when the lamp holder 21 moves downward, the two reflectors 44 rotate inward. When the lamp holder 21 moves upward, the two reflectors 44 rotate outward.

When the reflector 44 rotates outward to a near-horizontal position, the reflector 44 drives the receiving rod 68 to move upward. The upward movement of the receiving rod 68 causes the first moving plate 62 to move upward. Then, under the action of the first inclined surface 621, the first moving plate 62 drives the second moving plate 64 to move. Next, under the action of the second inclined surface 641, the second moving plate 64 drives the third moving plate 66 to move downward. The downward movement of the third moving plate 66 causes the air blowing pipe 662 to move downward. This allows the bottom of the air blowing pipe 662 to be aligned with the front of the reflector 44, thus facilitating the cleaning of the surface of the reflector 44. In summary, the cleaning mechanism 6 facilitates the cleaning of the surface of the reflector 44.

The third moving plate 66 moves downward, causing the third reset block 672 to move downward. The downward movement of the third reset block 672 presses against the third reset spring 673. When the back of the reflector 44 separates from the receiving rod 68, the third reset block 672 drives the third moving plate 66 to reset under the action of the third reset spring 673. In summary, the third reset component 67 facilitates the reset of the third moving plate 66.
