Description

[Technical Field]

[0001] The present invention relates to a device for adjusting the vertical gap between a vertically movable plant cultivation unit and a gutter mounting base. In particular, when cultivating plants in multiple stages of 3 to 7 stages using sunlight or LED light in a greenhouse or general commercial structure, the cultivation base can be lowered to the floor while maintaining horizontal balance without using a height-adjustable lift or ladder, allowing workers to harvest plants in a comfortable position, thereby maximizing the effects of improving productivity and reducing labor. The device also relates to adjusting the vertical gap between the gutter mounting base of the plant cultivation unit according to the growth of plants in the early stages of plant cultivation and the harvesting period, narrowing or widening the gap between the LED and the plants, thereby promoting growth and improving energy efficiency. [Background technology]

[0002] Generally, a plant cultivation unit made for growing vegetables and flowers has a plant gutter filled with soil and the vegetables and flowers are planted in it, and watered at regular intervals to ensure that the vegetables and flowers are supplied with sufficient moisture.

[0003] In recent years, when multiple plant cultivation units are installed in a limited space, it is difficult to secure the necessary space, so multi-tiered plant cultivation units have been used, in which multiple plant cultivation units are separated by a certain distance using support bases such as trusses.In other words, multiple plant cultivation units are stacked in an area where one plant cultivation unit could be placed.

[0004] In the case of conventional multi-tiered plant cultivation units, the plant cultivation unit is configured using a certain multi-tiered frame, so when harvesting plants in the upper tier of the multi-tiered structure, workers have no choice but to place a ladder or install a lift and climb up to the upper tier to harvest them.This makes plant harvesting inconvenient, requires a lot of effort, and takes a long time to complete.

[0005] However, in the past, only one rack was installed in the cultivation section, and when the harvesting lines were stacked on the floor, the load was almost zero.The side lines of the upper layer were under heavy load, and the pressure of them trying to descend to the bottom caused the center of gravity to shift to one side of the pinion gear, making it impossible to drive.In addition, if the cultivation section tilted to one side due to an imbalance in the center of gravity, there was a serious problem in that it had to be reinstalled to restore structural balance.

[0006] In addition, conventionally, the spacing between the cultivation sections was fixed, and during the initial growth of plants, it was necessary to supply LED light closely to increase energy efficiency. However, since the vertical spacing between the LEDs and the plants was far apart and there was no way to adjust it, there was a problem of reduced energy efficiency during plant cultivation and unnecessary power loss.

[0007] [Patent Document 1] Korean Patent Registration No. 10-1251903 [Patent Document 2] Korean Patent Publication No. 10-2023-0077307 [Patent Document 3] Korean Patent No. 10-242176 Summary of the Invention [Problem to be solved by the invention]

[0008] The present invention has been made to solve the above-mentioned drawbacks of the conventional technology, and its object is to provide a vertically movable plant cultivation unit and gutter mounting base vertical clearance adjustment device that, when harvesting plants in the upper layer of the plant cultivation unit, lowers the upper layer of the plant cultivation table to the floor using upper and lower racks installed on the top of the plant cultivation unit and a pinion gear installed between the racks, allowing the worker to harvest the upper layer of plants in a comfortable position in an unloaded state (stacked state), thereby improving productivity and maximizing the effect of labor savings.

[0009] Another object of the present invention is to provide a vertically movable plant cultivation unit and gutter mounting base vertical spacing adjustment device that can efficiently utilize the cultivation unit space and improve energy efficiency by reducing or increasing the vertical width of the gutter mounting base of stacked cultivation units when the upper cultivation unit is lowered, depending on the growth status of the plants during the initial and harvest periods. [Means for solving the problem]

[0010] The present invention, which has been made to achieve the above object, is broadly composed of a driving unit, a wire transport unit, a plant cultivation unit, and a gutter installation base vertical distance adjustment unit.

[0011] First, the drive unit is characterized in that a motor die is installed between the trusses, which are the structure, and a drive motor is connected to a reduction gear. A drive shaft with drive shaft connectors on both sides is installed continuously to the drive pinion gear shaft. An upper rack is installed above the drive pinion gear and an upper wire transfer pipe is installed at its end. A lower rack is installed below the drive pinion gear and a lower wire transfer pipe is installed at its end. A number of holes are formed in the wire transfer pipe, and wires are firmly fixed to the sides in the wire triple fastening fixing insertion holes (wire fixing part), thereby allowing the plant cultivation table to rise and fall.

[0012] Second, the wire transfer unit is configured such that the wire, which is firmly fixed to the upper wire transfer pipe, is fastened to the wire triple fastening insertion hole and transferred in opposite directions, and the two upper wire rollers rotate around the wire fixing part, causing the cutting table to rise and fall; the wire, which is firmly fixed to the lower wire transfer pipe, is fastened to the wire triple fastening insertion hole and transferred in opposite directions, and the two lower wire rollers rotate around the wire fixing part, 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 ascending cutting table and descending cutting table of the upper rack and the descending cutting table and ascending cutting table of the lower rack are arranged symmetrically at the same ratio to balance the forces.

[0013] Third, the plant cultivation unit is divided into a rising and a falling state. When rising, the turnbuckle attached to the wire fastens the cultivation stand, and the transport links are fixed to the gutter mounting base supporting the plant cultivation gutter with fixing bolts. The transport links slide along the inner diameter of the gutter mounting base to adjust the height. When a load is applied, the stop pins 36 fix the transport links, and the plant cultivation gutters of each layer rise sequentially from the upper layer under the load. When descending, when the lower gutter mounting base contacts the floor, the transport links attached to the gutter mounting base fixed to the layer directly above slide into the lower gutter mounting base and come into close contact with the ends of the upper and lower gutter mounting bases, and the gutter mounting bases of the next upper layer are gradually stacked in this order.

[0014] Fourth, the gutter mounting base vertical spacing adjustment unit has a plurality of stop pin holes formed in the gutter mounting base to adjust the spacing between the cultivation layers, and a vertically long hole formed in the transport link inserted into the gutter mounting base.When the stop pin is inserted into the stop pin hole at the desired position while moving the transport link up and down, the stop pin is inserted and fixed into the long hole of the transport link through the stop pin hole, thereby adjusting the spacing between the cultivation layers narrower in the early growth stage and adjusting the spacing wider as the plant grows, thereby saving energy and facilitating production. [Effects of the Invention]

[0015] The present invention as described above allows for cultivation of plants at multiple levels using sunlight or LED light in greenhouses or general commercial structures. The upper and lower racks and the pinion gear, drive motor, and reduction gear installed between them are used to maintain balance of the cultivation table, and the upper plant cultivation section can be lowered to the floor. This allows workers to harvest the upper plants in a comfortable position without using a height-adjustable lift or ladder, thereby improving productivity and maximizing labor-saving effects.

[0016] The present invention adjusts the height of the gutter mounting base while the plant cultivation unit is lowered by the pinion gear and the upper and lower racks, and adjusts the vertical interval of the gutter mounting base as desired according to the growth of the plants planted in the plant cultivation gutter. In the early stage of plant cultivation, the LED lights are placed close together to allow the plants to grow quickly, and as the plants grow, the LED lights are spaced apart appropriately, and the interval is efficiently adjusted according to the plant growth conditions, thereby improving energy efficiency and preventing power loss.

DETAILED DESCRIPTION OF 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 unit of the present invention, Fig. 2 is a diagram showing the configuration of the drive unit of the present invention, Fig. 3 is a diagram showing the non-stacked and stacked states of the present invention, Figs. 4 and 5 are diagrams for explaining the principle of balanced vertical movement of the cutting table of the present invention, Fig. 6 is a diagram for explaining the wire fixing unit of the present invention, Fig. 7 is a detailed diagram of the wire fixing unit of Fig. 5, Fig. 8 is a detailed diagram of parts A to D of Fig. 5, and Fig. 9 is a diagram showing the detailed configuration of the drive unit of the present invention. As shown in the figures, a drive unit 100 is provided at the upper end based on truss 2, posts 2b, and loops 2a, a wire transport unit 200 is connected to the drive unit 100 so as to operate in connection with the drive unit 100, and a plant cultivation unit 300 and a cutting table stacking unit 400 are connected so as to be moved up and down by the wire transport unit 200.

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

[0021] The drive motor 1 is connected to a drive shaft 6 by a drive shaft connector 7 so that the driving force of the drive motor 1 is transmitted through the drive shaft 6 .

[0022] An upper rack 4 and a lower rack 5 are installed on the upper and lower parts of the pinion gear 3, and are moved linearly left and right in opposite directions by the driving of the pinion gear 3. An upper wire transport pipe 8 is connected to the end of the upper rack 4, and a lower wire transport pipe 9 is connected to the end of the lower rack 5.

[0023] In addition, a wire fixing portion 12 is installed on each of the upper wire transport pipe 8 and the lower wire transport pipe 9, and this wire fixing portion 12 has a plurality of holes formed therein, either symmetrically or slightly inclined, and the wires 11 are connected to the sides in a zigzag pattern through these holes, so that they can withstand the force of the load.

[0024] That is, an upper wire transport pipe 8 is connected to the end of the upper rack 4, and a wire 11 is firmly connected to the upper wire transport pipe 8 by a wire fixing portion 12 of the upper wire transport pipe 8.

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

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

[0027] The operation of the present invention thus configured will now be described.

[0028] First, the driving unit of the present invention is configured by installing a motor die 1a on which a driving motor 1 can be installed between a truss 2, which is a structure, and connecting the driving motor 1 to a reduction gear 1b, and then installing a driving shaft 6 having driving shaft connectors 7 on both sides continuously to the axis of the pinion gear 3.

[0029] In addition, the driving unit has an upper rack 4 installed above the pinion gear 3 and an upper wire transport pipe 8 at its end, and a lower rack 5 installed below the pinion gear 3 and a lower wire transport pipe 9 at its end.

[0030] A wire fixing part 12 having a plurality of holes formed therein is installed on the upper wire transport pipe 8, and the wire 11 is inserted into the holes of the wire fixing part 12 on the side, so that the wire 11 connected to the plant cultivation part 300 is fixed without moving and withstanding the load even when it is raised and lowered.

[0031] That is, as shown in FIG. 7, the wire fixing portion 12 has three holes formed opposite to each other or formed at a slight incline, and the wire 11 is connected to the side surface of the wire fixing portion 12 in a zigzag manner through these holes.

[0032] In addition, as a means for transporting the wire, 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 spreads out in opposite directions, rotating the two upper wire rollers 13 on the left and right, and the wire 11 fixed to the lower wire transport pipe 9 is fastened to the wire fixing part 12 and spreads out in opposite directions, rotating the two lower wire rollers 14, thereby raising and lowering the plant cultivation part 300 and the cultivation table stacking part 400.

[0033] Therefore, as shown in FIG. 3, the plant cultivation unit 300 is in a heavy load non-layered state, and the lower cultivation table layering unit 400 is in a non-loaded layered state with plants layered thereon.

[0034] Referring to FIG. 4, the upper rack 4 moves to the right around the drive pinion gear 3, while the lower rack 5 moves to the left. The wire 11 connected to the upper rack 4 and fixed to the upper wire transport pipe 8 causes the cutting tray Z1 fastened to the upper wire roller 13 on the left side to rise, and the cutting tray Z2 is lowered and stacked around the wire fixing part 12 fastened to the upper wire roller 13a on the right side.

[0035] In addition, the cutting table Z3 is raised through the right lower wire roller 14a around the wire fixing part 12 by the wire 11 fixed to the lower wire transfer pipe 9 connected to the lower lower rack 5 around the pinion gear 3, and the cutting table Z4 fastened to the left lower wire roller 14 is lowered and stacked.

[0036] At this time, in the structure in which the drive pinion gear 3, the upper upper rack 4, and the lower lower rack 5 are connected due to the lowering stacking (no load) of the cutting table Z2 connected to the upper wire transfer pipe 8 and the rising (heavy load) of the cutting table Z1, and the rising (heavy load) of the cutting table Z3 connected to the lower wire transfer pipe 9 and the falling (no load) of the cutting table Z4, the horizontal load of the cutting table is changed when the drive pinion gear 3 rotates to the left, so that the upper rack 4 moves linearly to the left and the lower rack 5 moves linearly to the right. As the load of the drive pinion gear 3 is neutral, the force of the drive motor 1 can be minimized according to the seesaw principle when the drive motor 1 rotates due to the rising and falling of each cutting table Z1 to Z4.

[0037] In addition, the height of the multi-layered cutting table is 2 to 4 m, and in order to achieve sufficient rising and falling stacking, the transfer length of cutting table Z1 and cutting table Z2 must exceed the travel distance of the wire rollers 13 and 14 on both sides to enable smooth transfer without mutual interference.

[0038] In the present invention, as shown in FIG. 5, an upper pipe roller 15 and a lower pipe roller 15a are provided, and it is preferable that the upper and lower wire transport pipes 8 and 9 move linearly in their own positions and that upper and lower wire roller separation prevention pins 16 and 17 are provided to prevent the wire 11 bound to the upper and lower wire rollers 13 and 14 from separating.

[0039] 8A to 8D are diagrams showing the detailed configurations of the front, plan and side of the upper and lower wire rollers 13 and 14 at portions A, B, C and D in FIG.

[0040] Meanwhile, the vertical spacing adjustment operation of the gutter mounting base 33 of the present invention will be described as follows.

[0041] Fig. 9 is a diagram showing a vertical spacing adjustment device for a plant cultivation stand of the present invention, Fig. 10 is a perspective view of the plant cultivation stand of the present invention, Fig. 11 is an exploded perspective view of the plant cultivation stand of the present invention, and Fig. 12 is a diagram for explaining the vertical spacing adjustment of a gutter mounting stand 33 of the present invention. As shown in the figures, gutters 31 on which plants 29 can be arranged side by side are stacked at regular intervals, LEDs 32 for supplying light to the plants are installed horizontally below the gutters 31, and gutter mounting stands 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 state without load (stacked). The spacing between the gutter mounting stands 33 on the cultivation table is narrowed in the early stages of plant cultivation, and the spacing between the gutter mounting stands 33 on the cultivation table is widened during the harvest season, thereby adjusting the spacing between the plants 29 and the LEDs 32 to improve energy efficiency and save power.

[0043] As shown in FIG. 10, the cultivation beds are stacked in multiple stages by means of gutter installation stands 33, and the plants 29 planted in the plant gutters 31 located in the gutters 31 receive light from the LEDs 32 and grow.

[0044] In the past, the vertical spacing between the cultivating stands 25 was fixed, and even if the height was to be adjusted according to the growth conditions of the plants, the vertical height could not be adjusted because the gutter mounting stand 33 was fixed, making it difficult to utilize the space. To solve this problem, the present invention makes it possible to widen or narrow the vertical spacing between the cultivating stands 25 and the gutter mounting stand 33 as needed, thereby adjusting the stacking spacing of the cultivating stands 25.

[0045] Therefore, in the early stages of plant cultivation, if the distance between the LEDs 32 and the plants 29 is too great, energy efficiency will be poor and insufficient to promote the growth of the plants 29. Therefore, by narrowing the spacing between the gutter mounting bases 33 and narrowing the spacing between the gutters 31, the LEDs 32 installed below the gutters 31 will be closer to the plants, which will not only promote the growth and development of the plants more actively in the early stages, but will also improve energy efficiency.

[0046] Here, when the vertical spacing of the gutter mounting base 33 is constant, if the distance between the plant and the LED 32 is large, for example, during the initial cultivation of the plant, the energy efficiency of the LED 32 decreases and the energy consumption rate increases.

[0047] Figure 12 shows the gutter mounting base 33 of the present invention. The gutter mounting base 33 is configured such that, when the inside is empty, a transfer link 34 is inserted between the upper and lower gutter mounting bases 33, and a long hole 37 is formed vertically in the transfer link 34. The gutter mounting base 33 has a plurality of stop pin holes 35 formed therein, and stop pins 36 are selectively inserted into the stop pin holes 35 of the gutter mounting base 33 to adjust the height of the gutter mounting base 33.

[0048] In the unlikely event that the gap between the upper and lower stacking stages is narrowed to bring the plant and the LED 32 closer together, the gutter mounting base 33 has multiple stop pin holes 35 formed on the top and bottom, and a stop pin 36 is selectively inserted into the stop pin hole 35 at the desired position.The stop pin 36 will then be fixed to the long hole 37 of the transport link 34, and the gap between the gutter mounting base 33 and the transport link 34 can be adjusted, thereby adjusting the gap between the plant 29 and the LED 32.

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

[0050] When the vertical interval between the gutter mounts 33 narrows and the interval between the gutter 31 and the LED 32 becomes closer, the growth of the plants 29 located in the gutter 31 can be promoted.

[0051] That is, in the present invention, a plurality of height-adjustable stop pin holes 35 are formed on the gutter mounting base 33 to adjust the spacing between multiple cultivation layers, and after stacking, a stop pin 36 is installed at the lowest level of the height-adjustable stop pin holes 35, so that the spacing between cultivation layers is narrow in the early stages of growth, but the position of the stop pin 36 can be adjusted to widen the spacing as the plants grow, thereby saving energy and facilitating production.

[0052] The present invention as described above is not limited to the above-mentioned embodiments, and it goes without saying that a person having ordinary knowledge in the technical field to which the present invention pertains can easily apply various embodiments. [Explanation of symbols]
