[0003]

[0001] The present invention relates to an apparatus for adjusting the vertical interval between a plant cultivation part capable of vertical movement and a gutter mounting base. In particular, when cultivating plants in multiple stages at a height of 3 to 7 levels using sunlight or LED light in a greenhouse or a general commercial structure, when harvesting the plants in the upper plant cultivation part, without using a height adjustment lift or a ladder, the cultivation table descends to the floor while maintaining a horizontal balance and is stacked, enabling the operator to harvest in a comfortable posture, thereby maximizing the effects of productivity improvement and labor reduction. The vertical interval between the gutter mounting bases of the plant cultivation part is adjusted according to the growth of the plants at the initial stage and the harvesting stage of plant cultivation, and the interval between the LED and the plants is narrowed or widened to promote growth and improve energy efficiency.

Background Art

[0002] Generally, a plant cultivation part manufactured for growing vegetables and flowers is made by filling soil inside a plant gutter and planting vegetables and flowers, and watering is carried out at regular intervals to supply sufficient moisture to the vegetables and flowers.

[0003] In recent years, when multiple plant cultivation parts are provided in a limited space, it is difficult to secure space, so a multi-stage plant cultivation part in which a large number of plant cultivation parts are separated at regular intervals by a support base such as a truss is used. That is, a plurality of plant cultivation parts are stacked and used in an area where one plant cultivation part can be placed.

[0004] In the case of a conventional multi-stage plant cultivation part, since the plant cultivation part is constituted by a certain multi-stage frame, when harvesting the plants in the upper stage of the multi-stage, there is no choice but to place a ladder or install a lift for the operator to climb up to the upper layer for harvesting. Therefore, the harvesting work of the plants is inconvenient, requires a lot of labor, and takes a long working time.

[0005] However, conventionally, only one rack was installed in the cultivation section, and when the harvesting line was stacked on the floor, the load was almost zero. However, the pressure that caused the lateral lines of the upper layer to descend under heavy load caused the center of gravity to shift to one side from the pinion gear, which resulted in the inability to drive. Furthermore, if the cultivation section tilted to one side due to the imbalance in the center of gravity, it had to be re-installed to restore structural balance, which presented a serious problem.

[0006] Furthermore, conventionally, the spacing between the growing sections is fixed, and while it is necessary to supply LED light in close proximity to increase energy efficiency during the initial growth of plants, there is no way to adjust the vertical spacing between the LEDs and plants, resulting in reduced energy efficiency during plant cultivation and unnecessary power loss.

[0007] [Patent Document 1] Korean Registered Patent Publication No. 10-1251903 [Patent Document 2] Korean Published Patent Publication No. 10-2023-0077307 [Patent Document 3] Korean Registered Patent No. 10-242176 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] The present invention aims to solve the aforementioned drawbacks of conventional methods, and the objective of the present invention is to provide a vertically movable plant cultivation section and a gutter mounting stand vertical spacing adjustment device that, when harvesting plants from the upper plant cultivation section, lowers the upper layer of the plant cultivation stand to the floor using upper and lower racks installed above the plant cultivation section and pinion gears installed between those racks, allowing the worker to harvest the plants from the upper layer in a comfortable posture in an unloaded state (stacked state), thereby maximizing not only productivity but also labor savings.

[0009] Another object of the present invention is to provide a vertically movable plant cultivation section and a gutter mounting base vertical spacing adjustment device that can efficiently utilize the cultivation section space according to the growth stage of the plants in the initial and harvest stages by reducing or increasing the vertical width of the gutter mounting base of the stacked cultivation sections when the upper plant cultivation section is lowered, thereby improving energy efficiency. [Means for solving the problem]

[0010] The present invention, which aims to solve these problems, is broadly composed of a drive unit, a wire transport unit, a plant cultivation unit, and a gutter mounting base vertical spacing adjustment unit.

[0011] Firstly, the drive unit is characterized by the following configuration: a motor die is installed between trusses, which are structural members; a drive motor and a reduction gear are connected; a drive shaft equipped with drive shaft connectors on both sides is installed continuously on the drive pinion gear shaft; an upper rack and an upper wire transfer pipe are installed above the drive pinion gear and at its end; a lower rack and a lower wire transfer pipe are installed below the drive pinion gear; numerous holes are formed in the wire transfer pipe; and the wire is firmly fixed to the side in triple-fastening fixed insertion holes (wire fixing parts), thereby enabling the plant cultivation stand to rise and fall.

[0012] Secondly, the wire transfer section is configured such that a wire firmly fixed to the upper wire transfer pipe is fastened to a triple wire fastening insertion hole and transferred in opposite directions, while two upper wire rollers rotate around the wire fixing section, causing the cutting table to rise and fall. A wire firmly fixed to the lower wire transfer pipe is fastened to a triple wire fastening insertion hole and transferred in opposite directions, while two lower wire rollers rotate around the wire fixing section, causing the cutting table to rise and fall. When the pinion rotates, the upper rack moves linearly to the right (or left), and the lower rack moves linearly to the left (or right), and the rising and falling cutting tables of the upper rack, and the falling and rising cutting tables of the lower rack are arranged symmetrically in the same ratio to balance the forces.

[0013] Thirdly, the plant cultivation section is divided into upward and downward phases. During upward movement, the turnbuckle cultivation stand attached to the wire is secured, and the transfer link is fixed with fixing bolts to the gutter mounting stand that supports the plant cultivation gutter. The transfer link slides into the inner diameter of the gutter mounting stand to adjust the height, and when a load is applied, the stop pin 36 secures the transfer link, so that each layer of plant cultivation gutter receives the load from the upper layer and rises sequentially. During downward movement, when the lower gutter mounting stand contacts the floor surface, the transfer link secured to the gutter mounting stand fixed to the layer directly above slides into the lower gutter mounting stand and comes into close contact with the ends of the upper and lower gutter mounting stands, so that the next upper gutter mounting stand is gradually stacked in that order.

[0014] Fourthly, the gutter mounting base vertical spacing adjustment unit is characterized by having multiple stop pin holes formed in the gutter mounting base for adjusting the spacing between cultivation layers, and having elongated holes formed in the vertical direction in the transport link inserted into the gutter mounting base, so that when the transport link is moved up and down and a stop pin is inserted into the stop pin hole at the desired position, the stop pin is inserted and fixed into the elongated hole of the transport link through the stop pin hole, thereby adjusting the spacing between cultivation layers to be narrow in the early stages of growth and to be widened as the plants grow, resulting in energy saving and increased production efficiency.

Advantages of the Invention

[0015] In the present invention as described above, when cultivating plants at multiple heights by sunlight or LED light in a greenhouse or a general commercial structure, with the upper and lower racks, the pinion gears, drive motors, and reduction gears installed between them, while maintaining the balance of the cultivation table, the upper plant cultivation section can be lowered to the floor. Without using a height adjustment lift or a ladder, workers can harvest the upper plants in a comfortable posture, thus improving productivity and maximizing the labor-saving effect.

[0016] In the present invention, while lowering the plant cultivation section with a pinion gear and upper and lower racks, the height of the gutter mounting base is adjusted. According to the growth of the plants planted in the plant cultivation gutter, the vertical interval of the gutter mounting base can be arbitrarily adjusted. At the initial stage of plant cultivation, the LED light is placed close to the plants to enable them to grow quickly. During growth, the LED light is appropriately spaced apart, and the interval is efficiently adjusted according to the plant growth conditions, thereby improving energy efficiency and preventing power loss.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0019] FIG. 1 is a diagram showing the overall configuration of the plant cultivation part of the present invention, FIG. 2 is a diagram showing the configuration of the drive part of the present invention, FIG. 3 is a diagram showing the unstacked state and the stacked state of the present invention, FIGS. 4 and 5 are diagrams for explaining the balanced vertical movement operation principle of the cultivation table of the present invention, FIG. 6 is a diagram for explaining the wire fixing part of the present invention, FIG. 7 is a detailed view of the wire fixing part of FIG. 5, FIG. 8 is a detailed view of the parts A to D of FIG. 5, and FIG. 9 is a diagram showing the detailed configuration of the drive part of the present invention. As shown in the figure, a drive part 100 is provided at the upper end based on the truss 2, the post 2b, and the loop 2a, a wire transfer part 200 is connected so as to operate by being connected to the drive part 100, and a plant cultivation part 300 and a cultivation table stacking part 400 are connected so as to be vertically transferred by the wire transfer part 200.

[0020] A pinion gear 3 is installed in the motor die 1a at the upper end of the center of the truss 2, and a drive motor ① and a reduction gear 1b for rotating the pinion gear 3 are installed.

[0021] The drive motor 1 is connected to the drive shaft 6 by a drive shaft coupler 7, and the driving force of the drive motor 1 is configured to be transmitted through the drive shaft 6. "

[0022] An upper rack 4 and a lower rack 5 are installed above and below the pinion gear 3, and they move linearly from side to side in opposite directions when driven by the pinion gear 3. An upper wire transfer pipe 8 is connected to the end of the upper rack 4, and a lower wire transfer pipe 9 is connected to the end of the lower rack 5.

[0023] Furthermore, wire fixing parts 12 are installed in the upper wire transport pipe 8 and the lower wire transport pipe 9, respectively. Multiple holes are formed in these wire fixing parts 12, either symmetrically or slightly inclined, and the wires 11 are connected to the sides in a zigzag pattern through these holes, configured to withstand and withstand loads.

[0024] In other words, the upper wire transfer pipe 8 is connected to the end of the upper rack 4, and the wire 11 is firmly connected by the wire fixing part 12 of this upper wire transfer pipe 8.

[0025] Furthermore, a lower wire transfer pipe 9 is connected to the end of the lower rack 5, and the wire 11 is firmly connected to this lower wire transfer pipe 9 by a wire fixing part 12.

[0026] On the left and right sides of the wire 11, the plant cultivation section 300 and the cultivation bed stacking section 400 are connected by an upper wire roller 13 and a lower wire roller 14, and plants 29 are cultivated in the respective gutters 31 stacked on the plant cultivation section 300 and the cultivation bed stacking section 400.

[0027] The operation of the present invention, configured in this manner, will now be explained.

[0028] First, the drive unit of the present invention installs a motor die 1a between the truss 2, which is a structure, to which the drive motor 1 can be installed, and connects the drive motor 1 and the reduction gear 1b. A drive shaft 6, which is equipped with drive shaft connectors 7 on both sides, is installed continuously on the shaft of the pinion gear 3.

[0029] Furthermore, the drive unit has an upper rack 4 and an upper wire transfer pipe 8 installed at the end of the pinion gear 3 above the pinion gear 3, and a lower rack 5 and a lower wire transfer pipe 9 installed at the end of the pinion gear 3 below the pinion gear 3.

[0030] A wire fixing section 12 with multiple holes is installed on the upper wire transfer pipe 8. The wire 11 is inserted into the holes of the wire fixing section 12 on its side, and the wire 11 connected to the plant cultivation section 300 is fixed in place, remaining motionless under load even when the wire is raised and lowered.

[0031] In other words, as shown in Figure 7, the wire fixing section 12 is formed with three holes facing each other or slightly inclined, and the wire 11 is connected to these holes in a zigzag pattern along the side.

[0032] Furthermore, as a means of wire transport, with the upper wire transport pipe 8 connected to the upper rack 4, the wire 11 is fastened to the wire fixing part 12 and unfolds in opposite directions, causing the two upper wire rollers 13 on the left and right to rotate, while the wire 11 fixed to the lower wire transport pipe 9 is fastened to the wire fixing part 12 and unfolds in opposite directions, causing the two lower wire rollers 14 to rotate, thereby raising and lowering the plant cultivation section 300 and the cultivation stand stacking section 400.

[0033] Therefore, as shown in Figure 3, the plant cultivation section 300 will be in a state of unloaded stacking with heavy loads, while the lower cultivation stand stacking section 400 will be in a state of unloaded stacking with plants stacked on top.

[0034] Referring to Figure 4, as the upper rack 4 moves to the right around the drive pinion gear 3, the lower rack 5 moves to the left. With the cutting table Z1, which is fastened to the upper wire roller 13 on the left side, rising due to the wire 11 connected to the upper rack 4 and fixed to the upper wire transfer pipe 8, the cutting table Z2 is lowered and stacked around the wire fixing part 12 fastened to the upper wire roller 13a on the right side.

[0035] Furthermore, the cutting table Z3 is raised via the lower wire roller 14a on the right side, centered around the wire fixing part 12, by a wire 11 fixed to the lower wire transfer pipe 9 which is connected to the lower rack 5 at the bottom, with the pinion gear 3 at the center. The cutting table Z4, fastened to the lower wire roller 14 on the left side, is lowered and stacked.

[0036] In this structure, where the drive pinion gear 3 is connected to the upper rack 4 and the lower rack 5 by the lowering stacking state (no load) of the sewing table Z2 connected to the upper wire transfer pipe 8 and the raising state (high load) of the sewing table Z1, and the raising state (high load) of the sewing table Z3 connected to the lower wire transfer pipe 9 and the lowering state (no load) of the sewing table Z4, the horizontal load of the sewing tables is such that when the drive pinion gear 3 rotates to the left, the upper rack 4 moves linearly to the left and the lower rack 5 moves linearly to the right, and the force of the drive motor 1 can be minimized by the seesaw principle when the drive pinion gear 3 is in a load-neutral state and the drive motor 1 rotates due to the raising and lowering of each sewing table Z1 to Z4.

[0037] Furthermore, since the height of the multiple layers of cultivation tables is 2 to 4 meters, for sufficient upward and downward stacking to occur, the transport length of cultivation table Z1 and cultivation table Z2 must exceed the transport distance of the wire rollers 13 and 14 on both sides, in order for smooth transport without mutual interference to occur.

[0038] In the present invention, as shown in Figure 5, it is preferable to have an upper pipe roller 15 and a lower pipe roller 15a, and upper and lower wire transport pipes 8 and 9 move linearly in their respective positions, and upper and lower wire roller detachment prevention pins 16 and 17 to prevent the wires 11 bound to the upper and lower wire rollers 13 and 14 from detaching.

[0039] Figure 8 shows the detailed front, top, and side views of the upper and lower wire rollers 13 and 14 of parts A, B, C, and D in Figure 5.

[0040] On the other hand, the operation of adjusting the vertical spacing of the gutter mounting base 33 of the present invention will be described as follows.

[0041] Figure 9 shows a diagram illustrating the vertical spacing adjustment device for the plant growing stand of the present invention, Figure 10 is a perspective view of the plant growing stand of the present invention, Figure 11 is an exploded perspective view of the plant growing stand of the present invention, and Figure 12 is a diagram illustrating the vertical spacing adjustment of the gutter mounting base 33 of the present invention. As shown in the figures, gutters 31 on which plants 29 can be arranged in a row are stacked at regular intervals, LEDs 32 for supplying light to the plants are installed horizontally to the bottom of the gutters 31, and gutter mounting bases 33 are installed vertically on both sides of each gutter 31 and LED 32.

[0042] In Figure 9, (A) shows the state under load, and (B) shows the unloaded (stacked) state. The system is configured to improve energy efficiency and save electricity by adjusting the spacing between the plants 29 and LEDs 32 so that the spacing between the gutter mounting bases 33 of the cultivation stand is narrowed in the early stages of plant cultivation, and the spacing between the gutter mounting bases 33 of the cultivation stand is widened during the harvest period.

[0043] As shown in Figure 10, the growing trays are stacked in multiple layers by the gutter mounting base 33, and the plants 29 planted in the plant gutter 31 located in the gutter 31 grow under the light of the LED 32.

[0044] In existing systems, the vertical spacing of the cultivation stands 25 is fixed, and even if one tries to adjust the height according to the growth stage of the plants, the gutter mounting base 33 is fixed in a constant state, making it difficult to adjust the vertical height and thus difficult to utilize the space effectively. To solve this problem, the present invention allows the vertical spacing of the gutter mounting base 33 of the cultivation stands 25 to be widened or narrowed as needed, thereby adjusting the stacking spacing of the cultivation stands 25.

[0045] Therefore, in the early stages of plant cultivation, if the distance between the LED 32 and the plant 29 is large, the energy efficiency is poor and it is insufficient to promote the growth of the plant 29. By narrowing the spacing between the gutter mounting bases 33 and thus the spacing between the gutters 31, the LED 32 installed at the bottom of the gutters 31 gets closer to the plants, which not only promotes the early growth and development of the plants more actively but also improves energy efficiency.

[0046] In this case, if the vertical spacing of the gutter mounting base 33 is constant, for example, if the distance between the plant and the LED 32 is large during the initial cultivation of the plant, the energy efficiency of the LED 32 will decrease, and the energy consumption rate will increase.

[0047] Figure 12 shows a gutter mounting base 33 of the present invention. The gutter mounting base 33 has an open interior, and a transfer link 34 is inserted between the upper and lower gutter mounting bases 33. The transfer link 34 has an elongated hole 37 formed vertically, and the gutter mounting base 33 has a plurality of stop pin holes 35. The height of the gutter mounting base 33 is adjusted by selectively inserting stop pins 36 into the stop pin holes 35 of the gutter mounting base 33.

[0048] If it is necessary to narrow the vertical stacking distance of the growing trays to bring the plants and LEDs 32 closer together, the gutter mounting base 33 has multiple stop pin holes 35 formed vertically. By selectively inserting a stop pin 36 into the stop pin hole 35 at the desired position, the stop pin 36 is fixed to the elongated hole 37 of the transport link 34. By adjusting the distance between the gutter mounting base 33 and the transport link 34, the distance between the plants 29 and LEDs 32 can be adjusted.

[0049] However, with the transfer link 34 fixed to the lower end of the upper gutter mounting base 33, the height is adjusted by inserting or removing the transfer link 34 into or from the lower gutter mounting base 33.

[0050] When the vertical spacing between the gutter mounting bases 33 narrows and the distance between the gutter 31 and the LED 32 decreases, the growth of the plants 29 located on the gutter 31 can be promoted.

[0051] In other words, the present invention provides a gutter mounting base 33 with multiple height-adjustable stop pin holes 35 that allow for adjustment of the spacing between cultivation layers. After stacking, stop pins 36 are installed in the lowest of the height-adjustable stop pin holes 35. Initially, the spacing between cultivation layers is narrow, but the position of the stop pins 36 can be adjusted to widen the spacing as the plants grow, thereby saving energy and improving production efficiency.

[0052] The present invention, as described above, is not limited to the embodiments described above, and it goes without saying that a person with ordinary skill in the art to which the present invention belongs can easily apply various embodiments. [Explanation of Symbols]
