Description

Technical Field

[0001] This utility model relates to a three-layer lifting planting system, belonging to the field of dwarf plant planting. Background Technology

[0002] Dwarf plants generally refer to leafy vegetables, chives, and other plants grown in substrates. Currently, farmers still cultivate dwarf plants directly on large scale in fields. From the actual planting process, this method has the following drawbacks: First, it requires a large area. Second, the plants are close to the soil surface, requiring bending or squatting postures for weeding, pruning, etc., which is extremely physically demanding. Third, large-scale planting leads to uneven sunlight exposure. Fourth, after the plants mature, the fruits fall to the soil surface due to their weight, easily becoming dirty and difficult to clean, and are easily damaged by trampling during harvesting. For example, strawberries grown in sandy soil easily accumulate sand on the strawberries, making them prone to being trampled during harvesting. Utility Model Content

[0003] The purpose of this invention is to provide a three-layer lifting planting system that solves the defects of existing planting methods for dwarf plants.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A three-layer lifting planting system includes a planting rack with a drive device on it. Under the control of a control device, the drive device lifts and lowers multiple three-layer planting devices, with adjacent three-layer planting devices lifting in opposite directions. The drive device includes multiple lifting shafts arranged parallel to each other along the front-rear direction. Each lifting shaft is connected to a drive shaft via a commutator. The drive shaft is driven by a drive motor, which is connected to the control device. Multiple lifting components are spaced apart on each lifting shaft, and each lifting component, corresponding to the lifting shaft along the front-rear direction, is connected to one of the three-layer planting devices.

[0006] The advantages of this utility model are:

[0007] This utility model adopts a height-adjustable, staggered, three-dimensional aerial planting method, which effectively reduces the land area occupied. The height control allows plants to receive uniform light. Furthermore, aerial planting eliminates the need for bending or squatting, greatly reducing the labor of growers. The ripe fruits will not fall onto the soil surface, making them less likely to get dirty, and also prevent damage from trampling. It is suitable for widespread application.

[0012] like Figures 1 to 4 As shown, this utility model proposes a three-layer lifting planting system for planting dwarf plants. It includes a planting frame with a driving device mounted on it. Under the control of a control device, the driving device lifts and lowers multiple three-layer planting devices, with adjacent three-layer planting devices lifting in opposite directions. The driving device includes multiple lifting shafts 24 arranged parallel to each other along the front-rear direction. Each lifting shaft 24 is connected to a transmission shaft 21 via a commutator 23. The transmission shaft 21 is driven by a drive motor 22, which is connected to the control device. Multiple lifting components are spaced apart on each lifting shaft 24, and each lifting component, corresponding to the lifting components along the front-rear direction on each lifting shaft 24, is connected to a three-layer planting device.

[0013] Furthermore, the planting frame includes two fixed beams 12 arranged parallel to each other in the left-right direction. Each fixed beam 12 is supported by multiple columns 11. Multiple parallel connecting beams 13 connect the two fixed beams 12. The fixed beams 12 and the connecting beams 13 are located at the top of the planting frame. Each lifting shaft 24 is provided with a corresponding connecting beam 13. The lifting shaft 24 is parallel to the connecting beam 13. The lifting shaft 24 is connected to the corresponding connecting beam 13 via a support base 29. The lifting shaft 24 is rotatable relative to the support base 29. The left-right direction is a direction perpendicular to the front-back direction in the horizontal plane.

[0014] In the actual design, the lifting shaft 24 is located diagonally below the connecting beam 13, such as... Figure 3 As shown, the lifting shaft 24 is connected to the connecting beam 13 via multiple spaced-apart support seats 29. Figure 1 The upper end of the support base 29 is fixed to the connecting beam 13, while the lower end is rotatably connected to the lifting shaft 24.

[0015] In practical applications, the drive shaft 21 is connected to the output shaft of the drive motor 22 via a transmission mechanism, wherein the drive motor 22 is connected to one of the connecting beams 13 via a motor base 221.

[0016] In actual implementation, the transmission mechanism is, for example, a gear assembly, which includes a driving gear and a driven gear. The driving gear is mounted on the output shaft of the drive motor 22, and the driven gear is mounted on the transmission shaft 21. The driving gear meshes with the driven gear, so the drive motor 22 drives the driving gear to rotate, and the driving gear drives the transmission shaft 21 to rotate via the driven gear.

[0017] Figure 3 This illustrates the case where, along the left-right direction, the drive shaft 21 is positioned in the middle of the lifting shaft 24, and... Figure 3 The drive motor 22 shown is connected to a connecting beam 13 located in the middle along the front-rear direction via a motor mount 221. In actual implementation, connecting seats 211 should also be provided at both ends of the drive shaft 21, and the drive shaft 21 should be rotatably connected to the connecting seats 211. The connecting seats 211 are connected to the adjacent corresponding connecting beams 13. The connecting seats 211 are used to support and hold the drive shaft 21.

[0018] In the actual design, the lifting assembly includes a winding drum 25 mounted on the lifting shaft 24. One end of the wire rope 26 is fixed to the winding drum 25 and wound around it. The other end of the wire rope 26 is connected and fixed to a connector (not shown in the figure) on the corresponding connecting beam 13. A lifting pulley 27 is installed on the portion of the wire rope 26 that extends out of the winding drum 25. The lifting pulley 27 is connected to the three-layer planting device through turnbuckles. When viewed from the left and right, the winding directions of the wire ropes 26 of two adjacent lifting assemblies on the winding drum 25 are opposite, so that when viewed from the left and right, the lifting directions of two adjacent three-layer planting devices are opposite. That is, one three-layer planting device rises while the adjacent three-layer planting device falls.

[0019] In actual implementation, for example, if the wire rope 26 of a certain lifting component is wound clockwise on the winding drum 25, then the wire rope 26 of the adjacent lifting component is wound counterclockwise on the winding drum 25.

[0020] In the actual design, the three-layer planting device includes three planting troughs 32 arranged in parallel vertically. Each lifting component is connected to a hanging frame 31. The planting troughs 32 are mounted on the hanging frames 31 arranged in the front-to-back direction. The planting troughs 32 are horizontal in both static and lifting processes. The hanging frames 31 have three horizontal ribs (not shown in the figure) in the vertical direction. The horizontal ribs are used to support the planting troughs 32. The top of the hanging frame 31 is connected to the lifting pulley 27 through turnbuckles 28. That is, the hanging frame 31 is suspended below the lifting pulley 27. Multiple planting pots 33 are placed on each planting trough 32 in the front-to-back direction. The planting pots 33 are used to plant short plants.

[0021] In practical design, the hanging frame 31 is made of carbon structural steel (such as Q235), without limitations. The planting trough 32 is made of hot-dip galvanized high-strength structural steel (such as S320GD), also without limitations. The planting trough 32 is basin-shaped, with a width (viewed from left to right) generally between 33cm and 38cm, while the length (viewed from front to back) can be reasonably designed according to the greenhouse space. The bottom of the planting pot 33 has drainage and ventilation holes to prevent water accumulation and ensure the respiration of the plant roots.

[0022] Preferably, all three-layer planting devices arranged in the left-right direction are divided into two groups. One group moves upward while the other moves downward, and the height of each three-layer planting device in each group is consistent. Figure 1 As shown, 10 three-layer planting devices are arranged in a cross pattern, divided into two groups. The five three-layer planting devices in one group rise, while the five three-layer planting devices in the other group descend.

[0023] In use, dwarf plants are planted in planting pots 33, and then the planting pots 33 are placed on planting troughs 32. This allows the branches of the dwarf plants to extend out of the planting pots 33 and even the planting troughs 32, hanging down. Based on light requirements, the two sets of three-layer planting devices alternate their positions periodically. During this alternation, under the control of the control device, the drive motor 22 rotates, driving the transmission shaft 21 to rotate. The transmission shaft 21 then drives the lifting shafts 24 to rotate via the commutators 23. The lifting shafts 24 drive the winding drums 25 on them to rotate, causing the wire ropes 26 of each lifting component to wind or unwind on the winding drums 25. This, in turn, drives the three-layer planting device to rise or fall via the lifting pulleys 27. Figure 1 While one set of three-layer planting devices rises to a certain height, another set of three-layer planting devices descends to a certain height, and the two sets exchange lighting conditions, so that the plants on each set of three-layer planting devices can receive sufficient light, that is, the plants in all places achieve uniform lighting.

[0024] like Figure 4 The three-layer lifting planting system of this utility model also includes a supplementary lighting device, which includes supplementary lights 41 installed on each planting trough 32. The supplementary lights 41 are connected to the power supply equipment via cables, and the power supply equipment is connected to the control device and controlled by the control device.

[0025] In cases of insufficient light, such as cloudy days, the supplemental light 41 is turned on to ensure that all plants receive sufficient light and meet their light requirements at each growth stage. Generally, the supplemental light 41 uses LED lights, and its brightness can be adjusted as needed.

[0026] like Figure 4The three-layer lifting planting system of this utility model also includes a drip irrigation device. The drip irrigation device includes a water inlet pipe 51 erected near one end of the three-layer planting device. The inlet of the water inlet pipe 51 is connected to the water supply equipment via a main water inlet pipe (not shown in the figure). The water supply equipment is connected to and controlled by the control device. The water inlet pipe 51 is provided with multiple water outlets. Each water outlet is connected to the inlet of a water inlet pipe 52. A water inlet pipe 52 is provided on one side of each planting trough 32 along its own length direction (i.e., along the front-back direction). Multiple drip irrigation pipes 53 are installed on the water inlet pipe 52. The drip irrigation pipes 53 are used to drip water and fertilizer solution into the planting pot 33.

[0027] In actual design, the water inlet pipe 52 should be a flexible hose. This utility model can supply water and fertilizer solution to the plants in each planting pot 33 at regular intervals and in quantitative quantities through the drip irrigation device to meet the plant growth needs.

[0028] In this utility model, the control device, drive motor 22, power supply equipment, and water supply equipment are well-known devices or equipment in the field and will not be described in detail here.

[0029] In this invention, the commutator 23 is a servo planetary commutator, and is therefore not limited thereto.

[0030] This utility model defines the vertical direction, the front-back direction, and the left-right direction. The vertical direction is the up-and-down direction. The length direction of the lifting shaft 24 and the connecting beam 13 is the left-right direction. The front-back direction is the direction perpendicular to the left-right direction in the horizontal plane. The length direction of the transmission shaft 21 is the front-back direction. Figure 1 and Figure 3 As shown.

[0031] The advantages of this utility model are:

[0032] 1. This utility model adopts a height-adjustable, staggered, three-dimensional aerial planting method, which effectively reduces the land area occupied. The height control allows plants to receive uniform light. Furthermore, aerial planting eliminates the need for bending or squatting, greatly reducing the labor of growers.

For those skilled in the art, any obvious changes such as equivalent transformations or simple substitutions based on the technical solution of this utility model without departing from the spirit and scope of this utility model shall fall within the protection scope of this utility model.
