Description

Technical Field

[0001] This application relates to the field of plant cultivation technology, and in particular to a chain-type longitudinal conveyor planting device for plant factories. Background Technology

[0002] Plant factories are a modern agricultural system that relies on LED artificial light sources, soilless cultivation, and intelligent environmental control technology to achieve efficient year-round crop production in enclosed or semi-enclosed spaces. Through vertical planting, they significantly increase yield per unit area (10-25 times that of traditional agriculture) and have advantages such as water and land conservation, zero pesticide residues, and stable quality. They are widely used in the cultivation of leafy vegetables, fruit vegetables, medicinal plants, and in emergency supply, urban agriculture, and space agriculture.

[0003] In plant factories, to increase space utilization, existing technologies often employ solutions such as the chain-type multi-layer grafted seedling nursery machine based on image recognition and environmental factor automatic control disclosed in CN115669415A. This involves attaching seedling trays to a chain, which is driven by sprockets to rotate, thus moving the seedling trays within the space and improving space utilization. However, existing methods of connecting the seedling trays and other planting carriers to the chain often involve fixing the planting carrier to a chain pin. The planting carrier can rotate around the chain pin, allowing it to remain vertical under its own weight while the chain drives its movement, thus maintaining the stability of the planting carrier's shape. The frictional force on the chain pin is mainly generated by the weight of the planting carrier and the tension between different parts of the chain. Furthermore, with a large number of planting carriers on the chain and a heavy load on the chain, the rotational friction that the planting carrier needs to overcome to remain vertical is significant. This can easily lead to difficulty in rotating the planting carrier, causing it to tilt and reducing the stability of the planting device in moving the planting carrier. Summary of the Invention

[0004] In order to improve the uniformity of light exposure to plants and reduce wear and tear on the planting device, thereby increasing the service life of the planting device, this application provides a chain-type longitudinal conveyor planting device for plant factories.

[0005] The chain-type longitudinal conveyor planting device for plant factories provided in this application adopts the following technical solution: A chain-type longitudinal conveyor planting device for a plant factory includes a spatial movement component, a lighting component, and multiple planting carriers. The multiple planting carriers are arranged on the spatial movement component along the horizontal and vertical directions. The spatial movement component can provide support for the planting carriers and drive the planting carriers to move. The lighting component can provide light to the plants in the planting carriers. The planting carrier includes a rotating shaft, a support frame, and a planting box. The rotating shaft is connected to the spatial movement component and passes through the support frame. The planting box is installed on the support frame. The support frame can rotate around the rotating shaft so that the planting box can maintain an upward-facing position by its own gravity during movement.

[0006] By adopting the above technical solution, when the spatial movement component moves the planting carrier, the spatial position of the planting carrier changes. During this movement, the support frame of the planting carrier can rotate around a pivot axis, allowing the planting box to maintain its opening facing upwards under its own weight. This prevents the plants and growing medium from spilling, ensuring a stable growth environment for the plants, while the lighting component provides illumination for their growth. This solution, by having the support frame rotate around a pivot axis connected to the spatial movement component, ensures that the rotational friction that the planting box needs to overcome to maintain verticality is primarily generated by its own weight. This reduces the friction that the planting box needs to overcome during rotation, improves the ease of rotation, and ultimately enhances the stability of the planting carrier during movement.

[0007] Preferably, the lighting assembly includes a power transmission assembly, a power supply assembly, and a plurality of lighting lamps. Each lighting lamp corresponds to one of the planting carriers and is installed on the planting carrier. The lighting lamps are connected to each other through the power transmission assembly, which is capable of transmitting power between the lighting lamps. The power supply assembly is connected to the power transmission assembly to provide power to the lighting lamps.

[0008] By adopting the above technical solution, when the spatial movement component does not need to drive the planting carrier to move, the power supply component provides power to the lighting lamps on each planting carrier through the power transmission component. The lighting lamps illuminate the plants on the planting carrier. When the spatial movement component needs to drive the planting carrier to move, the power supply component can simultaneously supply power to the lighting lamps on the moving planting carrier, ensuring the stability of plant lighting. This application, by setting lighting lamps and power supply components on each planting carrier, can supply power to the lighting lamps in both moving and stationary states. On the one hand, this eliminates the need for the spatial movement component to continuously drive the planting carrier to maintain uniform plant lighting. On the other hand, it ensures that each planting carrier receives uniform light, which improves the uniformity of plant light exposure and reduces wear on the planting device, thereby extending the service life of the planting device.

[0009] Preferably, there are two sets of power transmission components, which are respectively disposed on both sides of the support frame and used as the positive and negative lines of the lighting lamp. Each power transmission component includes a wire group and a first conductive cylinder. The first conductive cylinder corresponds one-to-one with the rotating shaft. The first conductive cylinder is insulated and installed on the support frame and is electrically connected to the lighting lamp. Adjacent first conductive cylinders are electrically connected to each other through the wire group.

[0010] By adopting the above technical solution, two sets of power transmission components are set on both sides of the support frame as positive and negative lines of the lighting lamp. The first conductive cylinder corresponds to the rotating shaft and is insulated and installed on the support frame and is electrically connected to the lighting lamp. Adjacent first conductive cylinders are electrically connected through wire groups. The wire groups can adapt to the changes in the distance between two adjacent planting carriers, thereby effectively constructing a stable power transmission circuit and ensuring a stable and reliable power supply for the lighting lamp.

[0011] Preferably, the rotation axis of the first conductive cylinder is collinear with the rotation axis of the rotating shaft, and both ends of the wire group are electrically connected to a second conductive cylinder. The second conductive cylinder is rotatably sleeved on the first conductive cylinder and electrically connected to the first conductive cylinder. The two second conductive cylinders on the first conductive cylinder are arranged in an arrangement.

[0012] By adopting the above technical solution, the second conductive cylinder is rotated and sleeved on the first conductive cylinder and electrically connected, so as to realize the flexible connection between the wire group and the first conductive cylinder. This ensures that the power transmission component can stably transmit power during the movement of the planting carrier, avoids the wire group from getting tangled during the rotation of the planting carrier, and improves the convenience and stability of power supply.

[0013] Preferably, the wire assembly is provided with a first telescopic spring, the wire assembly is threaded through the first telescopic spring, both ends of the first telescopic spring are fixedly connected to the wire assembly, the length of the wire assembly located on the first telescopic spring is greater than the length of the first telescopic spring in its free state, and the first telescopic spring can pull the wire assembly into a taut state.

[0014] By adopting the above technical solution, the first telescopic spring can pull the wire group to a taut state, avoiding tangling or knotting of the wire group during the movement of the planting carrier, ensuring the stability of power transmission of the power transmission component, and thus ensuring the stability of the light from the lighting lamp to the plant.

[0015] Preferably, the power supply components are in two groups, each group corresponding to one group of power transmission components. Each group of power supply components includes a bare conductor and a receiving component. The bare conductor is insulated from the spatial movement component. The trajectory of the bare conductor is the same as the movement trajectory of the first conductive cylinder. The spatial movement component can drive the bare conductor to move synchronously with the first conductive cylinder. The bare conductor is electrically connected to the first conductive cylinder. The two groups of receiving components are electrically connected to the positive and negative poles of the power supply, respectively. The receiving component is slidably electrically connected to the bare conductor.

[0016] By adopting the above technical solution, the two sets of power supply components correspond to the two sets of power transmission components, which can efficiently and stably deliver positive and negative power to the lighting lamps. The bare conductor moves along the same trajectory as the first conductive cylinder and moves synchronously, ensuring the continuity of power transmission. The receiving component is slidably electrically connected to the bare conductor, ensuring a continuous and stable power supply to the lighting lamps even during the movement of the planting carrier, further improving the stability of plant light exposure, and ensuring the flexibility and reliability of power supply.

[0017] Preferably, the power receiving component includes a conductive wheel and a conductive shaft. The conductive shaft is insulated from and connected to the frame and electrically connected to the power supply. The conductive wheel is coaxially rotatably connected to the conductive shaft and can be pressed against the bare wire. The bare wire can drive the conductive wheel to rotate.

[0018] By adopting the above technical solution, the conductive wheel of the receiving component is coaxially rotated and electrically connected with the conductive shaft and can be pressed against the bare wire. The bare wire drives the conductive wheel to rotate, which can realize the sliding electrical connection between the receiving component and the bare wire, ensuring that the power supply component supplies power to the power transmission component, thereby ensuring that the lighting provides stable light to the plants, and also reducing the friction loss between the receiving component and the bare wire, improving the reliability and service life of the power supply system.

[0019] Preferably, the spatial movement component includes a driving component and two sets of parallel first chain drive mechanisms. The two sets of first chain drive mechanisms are respectively arranged on both sides of the support frame. The sprockets in the first chain drive mechanisms are rotatably connected to the frame. The two ends of the rotating shaft are respectively fixedly connected to the chain pins in the chains of the two sets of first chain drive mechanisms. The driving component is connected to the first chain drive mechanism so as to drive the sprockets in the first chain drive mechanism to rotate.

[0020] By adopting the above technical solution, the driving component drives the sprocket in the first chain transmission mechanism to rotate, which in turn drives the chain to rotate, causing the rotating shaft fixedly connected to the chain pin inside the chain to move, thereby realizing the movement of the planting carrier, improving the space utilization rate of the planting device, and providing stable and reliable power for the movement of the planting carrier.

[0021] Preferably, each sprocket is coaxially fixed with an insulating guide wheel, and the bare wire is wound around the insulating guide wheel so that the insulating guide wheel can drive the bare wire to rotate.

[0022] By adopting the above technical solution, the bare conductor can be driven to rotate by the insulated guide wheel, which can better keep the bare conductor and the first conductive cylinder moving synchronously, ensuring that the power supply component provides stable power to the lighting component.

[0023] Preferably, a second brush is insulated and installed on the rotating shaft. The second brush is electrically connected to the first conductive cylinder and connected to the bare wire via a wire, which is embedded inside the rotating shaft.

[0024] By adopting the above technical solution, during the movement of the planting carrier, the angle between the planting carrier and the chain will change, causing relative rotation between the support frame and the rotating shaft. Through the sliding connection between the second brush and the first conductive cylinder, the entanglement of the wires is avoided, thereby improving the stability of power transmission.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By having the support frame rotate around the rotation axis, and the rotation axis being connected to the spatial movement component, the rotational friction force that the planting box needs to overcome to maintain verticality is mainly generated by its own weight. This reduces the friction force that the planting box needs to overcome to rotate, improves the convenience of rotating the planting box, and thus improves the stability of the planting carrier during movement. 2. By setting up lighting and power supply components on each planting carrier, power can be supplied to the lighting components in both moving and stationary states. This allows for individual lighting for each plant on each planting carrier, preventing the planting carriers from blocking each other's light, resulting in more uniform light exposure, consistent plant growth, and improved plant quality. Furthermore, it eliminates the need for a space-moving component to continuously move the planting carriers to maintain uniform lighting, thus reducing wear on the drive mechanism and extending the service life of the planting device. 3. The power supply is electrically connected to the bare wires through the conductive wheel, ensuring that the lighting components provide stable light to the plants, and also reducing frictional losses between the receiving components and the bare wires, thereby improving the reliability and service life of the power supply system.

Detailed Implementation

[0035] The following will be combined with the appendix Figures 1-8 The technical solutions in the embodiments of the present invention are further described in detail below. The described embodiments are only possible technical implementations of the present invention, but are not limited thereto. Those skilled in the art can combine the embodiments of the present invention to obtain other embodiments without creative effort, which are also within the protection scope of the present invention.

[0036] This application provides a chain-type longitudinal conveyor planting device for plant factories, which adopts the following technical solution.

[0037] Example 1 Reference Figure 1 and Figure 2A chain-type longitudinal conveyor planting device for a plant factory includes a spatial movement component 1, a lighting component 2, and multiple planting carriers 3. The spatial movement component 1 is mounted on a frame, and the multiple planting carriers 3 are arranged along the horizontal and vertical directions on the spatial movement component 1, allowing for more planting carriers 3 to be placed within a limited space, thus improving space utilization. The spatial movement component 1 can drive the planting carriers 3 to move cyclically. Each planting carrier 3 is rotatably connected to the spatial movement component 1, ensuring that the planting carrier 3 remains vertical due to its own weight during the process of the spatial movement component 1 driving the planting carrier 3. In this embodiment, the lighting component 2 includes lamp groups 21. Multiple lamp groups 21 are fixedly mounted on the frame and located between the crests formed by the spatial movement component 1, facing the planting carriers 3.

[0038] In this embodiment, the spatial movement component 1 includes a drive unit 11 and two sets of parallel first chain drive mechanisms 12. The two sets of first chain drive mechanisms 12 are symmetrically arranged. The chains 122 in the first chain drive mechanisms 12 are arranged in a longitudinal wave pattern on the frame and are horizontally positioned at the top of the frame. The sprockets 121 in the first chain drive mechanisms 12 are rotatably connected to the frame and are located at the turning point of the chains 122. The two sprockets 121 that are partially opposite to each other are connected by a shaft, so that the two sprockets 121 rotate synchronously, thereby ensuring that the two chains 122 move synchronously. The drive unit 11 includes a drive motor 111 and a second chain drive mechanism 112. The drive motor 111 is fixedly mounted on the base. The output shaft of the drive motor 111 is connected to the second chain drive mechanism 112 and the two opposite sprockets 121 in the first chain drive mechanism 12 through a reducer, so as to drive the chains 122 in the first chain drive mechanism 12 to move. A support plate is provided at the bottom of the planting device, and the chain 122 in the first chain drive mechanism 12 is attached to the support plate to ensure that the chain 122 remains horizontal over a long span.

[0039] In this embodiment, the planting carrier 3 includes a rotating shaft 31, a support frame 32, and a planting box 33. The support frame 32 is located between the chains 122 in the two first chain drive mechanisms 12. The planting box 33 is fixedly installed on the support frame 32 and filled with soil to provide a suitable environment for plant growth. Both ends of the rotating shaft 31 are fixedly connected to the chain pins on the two chains 122. The rotating shaft 31 passes through the support frame 32 and is rotatably connected to it. The rotating shaft 31 is offset from the center of the support frame 32, allowing the planting box 33 to maintain a vertically upward position under its own weight, preventing the plants and growing medium from spilling and ensuring a stable growth environment for the plants. The dimensions of the support frame 32 can be determined based on the diameter of the sprockets 121 in the first chain drive mechanism 12 to ensure that the support frame 32 does not interfere with the shaft between the two sprockets 121.

[0040] The implementation principle of Example 1 is as follows: During the movement of the planting carrier 3 by the first chain drive mechanism 12, the support frame 32 of the planting carrier 3 can rotate around the rotating shaft 31, so that the planting box 33 relies on its own weight to keep the opening facing upwards during movement, preventing the plants and media inside the planting box 33 from spilling, ensuring a stable growth environment for the plants, and the lighting component 2 provides light conditions for the growth of the plants. In this solution, by having the support frame 32 rotate around the rotating shaft 31, and the rotating shaft 31 is connected to the chain 122 in the first chain drive mechanism 12, the rotational friction force that the planting box 33 needs to overcome to maintain verticality is mainly generated by its own weight, reducing the friction force that the planting box 33 needs to overcome during rotation, improving the convenience of rotation of the planting box 33, and thus improving the stability of the planting carrier 3 during movement.

[0041] Example 2 Reference Figure 3 and Figure 4 The difference between this embodiment and embodiment 1 is that the lighting component 2 includes a lighting lamp 22, a power transmission component 23, and a power supply component 24. The lighting lamp 22 corresponds one-to-one with the planting carrier 3. In this embodiment, the lighting lamp 22 is an LED light strip 221. The LED light strip 221 is fixedly mounted on the support frame 32 and located below the rotating shaft 31. The LED light strip 221 is arranged along the length of the planting box 33 to improve the uniformity of light received by the plants in the planting box 33. There are two sets of power supply components 24. One set of power supply components 24 is connected to the positive terminal of the power supply and the power transmission component 23 of the positive terminal as a positive line. The other set of power supply components 24 is connected to the negative terminal of the power supply and the power transmission component 23 of the negative terminal as a negative line. This makes the positive terminal of the power supply, the power supply component 24 of the positive line, the power transmission component 23 of the positive line, the LED light strip 221, the power transmission component 23 of the negative line, the power supply component 24 of the negative line, and the negative terminal of the power supply form a circuit. This circuit can remain open during the movement of the planting carrier 3.

[0042] During normal plant growth, when the spatial movement component 1 is not needed to move the planting carrier 3, power is supplied to the LED light strips 221 on each planting carrier 3 through the power supply component 24 and the power transmission component 23. The lighting component 2 illuminates the plants on the planting carrier 3, ensuring uniform light exposure for each plant. When watering or other treatments require the spatial movement component 1 to move the planting carrier 3, the power supply component 24 simultaneously supplies power to the lighting components 2 on the moving planting carrier 3, ensuring stable light exposure for the plants.

[0043] By setting LED light strips 221 and power supply components 24 on each planting carrier 3, power can be supplied to the LED light strips 221 whether they are moving or stationary. This allows each plant on the planting carrier 3 to be individually illuminated, avoiding the planting carriers 3 blocking each other's light, making the plants receive light more evenly, ensuring consistent plant growth, improving plant quality, and eliminating the need for the first chain drive mechanism 12 to continuously move the planting carrier 3 to maintain uniform light, thus reducing wear on the first chain drive mechanism 12 and extending the service life of the planting device.

[0044] Reference Figure 3 and Figure 5 Each power supply assembly 24 includes bare wires 241 and a receiving component 242. An insulating guide wheel 243 is coaxially fixed on each sprocket 121 of the first chain drive mechanism 12. The insulating guide wheel 243 is located outside the sprocket 121 and has a groove for the bare wires 241 to be inserted, thereby improving the reliability of the insulating guide wheel 243 driving the bare wires 241 to rotate. The bare wires 241 are connected end-to-end and wound around the insulating guide wheel 243. The bare wires 241 are located between the sprocket 121 and the second chain drive mechanism 112. The diameter of the insulating guide wheel 243 is equal to the diameter of the sprocket 121 on the first chain drive mechanism 12, so that the trajectory of the bare wires 241 is equal to the trajectory of the chain 122 in the first chain drive mechanism 12 and is arranged parallel to it.

[0045] The power receiving component 242 includes a conductive wheel 2421 and a conductive shaft 2422. An insulated power receiving frame 2423 is fixedly mounted on the frame. The conductive shaft 2422 is rotatably connected to the power receiving frame 2423. The conductive shaft 2422 is electrically connected to the power source through a first brush 2424. The two conductive shafts 2422 are respectively connected to the positive and negative terminals of the power source. The conductive wheel 2421 is coaxially fixedly mounted on the conductive shaft 2422 and abuts against the bare wire 241, so that the positive terminal of the power source and the bare wire 241 are in a conductive state. When the bare wire 241 rotates, it drives the conductive wheel 2421 to rotate, thereby forming rolling friction between the bare wire 241 and the conductive wheel 2421, reducing frictional loss between the power receiving component 242 and the bare wire 241, and improving the reliability and service life of the power supply system.

[0046] Reference Figure 6 , Figure 7 and Figure 8In this embodiment, the power transmission component 23 includes a wire group 231 and a first conductive tube 232. The wire group 231 is a single wire with an insulating sheath. The first conductive tube 232 corresponds one-to-one with the rotating shaft 31. The first conductive tube 232 is coaxially sleeved on the rotating shaft 31 and fixed and insulatedly connected to the support frame 32. Two first conductive tubes 232 on the same support frame 32 are respectively arranged on the outside of the support frame 32. The two first conductive tubes 232 are electrically connected to the positive and negative terminals of the LED light strip 221 through wires. Both ends of the wire group 231 are electrically connected to a second conductive cylinder 233. The second conductive cylinder 233 on the connection end of two adjacent wire groups 231 are rotatably sleeved on the first conductive cylinder 232. The second conductive cylinder 233 and the first conductive cylinder 232 are adapted to each other and form an electrical connection. The two second conductive cylinders 233 on the same first conductive cylinder 232 are arranged along the axial direction of the first conductive cylinder 232, so that the positive lines of multiple LED light strips 221 are interconnected and the negative lines are also interconnected. Both ends of the first conductive cylinder 232 are respectively provided with baffles to prevent the second conductive cylinder 233 from sliding axially, thereby improving the stability of the connection between the second conductive cylinder 233 and the first conductive cylinder 232.

[0047] A first telescopic spring 234 is sleeved on the wire assembly 231. Both ends of the first telescopic spring 234 are fixedly connected to the wire assembly 231. The length of the wire assembly 231 between the two fixed points of the first telescopic spring 234 is greater than the length of the first telescopic spring 234 in its free state, so that the first telescopic spring 234 pulls the wire assembly 231 into a taut state.

[0048] During the movement of the planting carrier 3 driven by the chain 122, the distance and position between the two rotating shafts 31 will change. When the distance between the two rotating shafts 31 changes, the length of the wire group 231 is adjusted by the extension and retraction of the first telescopic spring 234, so that the wire group 231 remains taut during the change of the distance between the rotating shafts 31, avoiding the wire group 231 from getting tangled or knotted during the movement of the planting carrier 3, and ensuring the stability of power transmission of the power transmission component 23.

[0049] At the turning point of the chain 122, the positions of the two rotating shafts 31 will change. During the change of position of the two rotating shafts 31, the second conductive cylinders 233 at both ends of the wire group 231 rotate around the first conductive cylinder 232 to prevent the wire group 231 from getting tangled on the rotating shafts 31, thereby achieving a flexible connection between the wire group 231 and the first conductive cylinder 232 and ensuring that the power transmission component 23 can stably transmit power during the movement of the planting carrier 3.

[0050] Each end of the rotating shaft 31 on one of the support frames 32 is fixedly equipped with a second brush 235. The second brush 235 is insulated from the rotating shaft 31. Each second brush 235 corresponds to a first conductive cylinder 232 on the support frame 32. The second brush 235 slides against the end face of the first conductive cylinder 232. Each brush is connected to a bare wire 241 on the corresponding side via a wire. The wire is embedded in the rotating shaft 31, allowing the wire to pass through the chain 122. As the chain 122 moves the planting carrier 3, the angle between the planting carrier 3 and the chain 122 changes, causing relative rotation between the support frame 32 and the rotating shaft 31. The sliding connection between the brush and the first conductive cylinder 232 prevents the wire from tangling, thereby improving the stability of power transmission.

[0051] The implementation principle of Example 2 is as follows: When the planting carrier 3 does not need to be moved, the positive terminal of the power supply is transmitted to the LED light strip 221 through the conductive wheel 2421, bare wire 241, second brush 235, and first conductive cylinder 232 in the positive terminal line, and then transmitted to the negative terminal of the power supply through the first conductive cylinder 232, second brush 235, bare wire 241, and conductive wheel 2421 in the negative terminal line, thereby forming a circuit for the LED light strip 221 to emit light. The lighting component 2 illuminates the plants on the planting carrier 3, ensuring the uniformity of light received by each plant on the planting carrier 3.

[0052] When the planting carrier 3 needs to be moved, the chain 122 drives the planting carrier 3 to move. The bare wire 241 moves synchronously with the planting carrier 3 and is kept in a conductive state through the contact between the bare wire 241 and the conductive wheel 2421. The brush and the first conductive cylinder 232, and the first conductive cylinder 232 and the second conductive cylinder 233 are kept in a conductive state during the movement of the planting carrier 3, so that the positive terminal of the power supply, the LED light strip 221, and the negative terminal of the power supply are all kept in a conductive state, so that the LED light strip 221 can still illuminate the plant during the movement of the planting carrier 3.

[0053] By setting LED light strips 221 and power supply components 24 on each planting carrier 3, power can be supplied to the lighting components 2 in both moving and stationary states. This allows for individual illumination of the plants on each planting carrier 3, preventing the planting carriers 3 from blocking each other's light, making the plants receive more uniform light, ensuring consistent plant growth, improving plant quality, and eliminating the need for the space moving components 1 to continuously move the planting carriers 3 to maintain uniform illumination. This reduces wear on the drive mechanism and extends the service life of the planting device.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
