Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural equipment, and in particular to a containerized forage cultivation system and method based on mobile operations. Background Technology

[0002] Containerized hydroponic forage systems, with their advantages of standardization, mobility, and environmental control, have become an important development direction for modern intensive agriculture. In order to maximize yield within the limited container volume, existing technologies generally adopt high-density planting layouts, that is, setting up multi-layer or even full-height cultivation racks inside the container to maximize the use of vertical space.

[0003] However, this design concept of maximizing planting space, while increasing planting density, also brings serious negative consequences—a severe lack of working space. Because most of the internal space is occupied by fixed cultivation shelves, pipe networks, and environmental equipment, the passage and operating space left for operators to perform daily inspections, maintenance (such as replanting and repair), and final harvesting is compressed to the extreme, usually leaving only narrow passages, where it is even difficult for personnel to turn around or squat down.

[0004] This contradiction of "having space for planting but no space for operation" is particularly prominent in the forage harvesting process. Forage has a short growth cycle and requires frequent, large-scale harvesting. During harvesting, operators must squeeze into cramped spaces, facing heavy, moisture-laden forage trays, often forced to use extremely awkward postures to painstakingly pull, move, and pass the trays from layers of shelves. This process is not only extremely labor-intensive and inefficient, easily causing muscle strain, but also poses safety risks such as collisions and falls due to the confined space. Furthermore, the fixed irrigation networks and cables further hinder personnel movement and visibility, making the entire harvesting operation environment harsh and the experience extremely poor, severely restricting the improvement of production efficiency and the widespread application of this technology.

[0005] Therefore, how to resolve the fundamental contradiction between "planting density" and "operating space" within containers from a system design perspective, and create safe, efficient, and humane operating conditions for critical operations (especially harvesting operations) while ensuring high-density planting, has become a pressing technical challenge in this field. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a containerized forage cultivation system based on mobile operations.

[0007] The present invention provides a containerized forage cultivation system based on mobile operations, which adopts the following technical solution: A containerized forage cultivation system based on mobile operations includes: The container body forms a closed cultivation space inside; A pallet rack is fixedly installed inside the container to support hay pallets. The pallet rack is provided with an inclination angle that causes the pallets to slide downwards under the action of gravity. A stop mechanism is provided at the end of the pallet rack. The stop mechanism has a locked state to prevent the pallets from sliding and a released state to allow the pallets to slide. Sensor components, installed inside the container, are used to monitor temperature, humidity, CO2 concentration, and light intensity; The mobile operating platform includes a walking mechanism for driving the platform to move along a track pre-installed inside the container; a material receiving section disposed on the mobile operating platform for receiving hay pallets that slide off the pallet placement rack; a material stacking section disposed on the mobile operating platform for stacking the pallets received by the material receiving section; and a triggering mechanism for triggering the stop mechanism to allow the pallets to slide off. A spraying assembly, installed on the mobile work platform, is used to spray the plants in the tray.

[0008] Through the aforementioned technical solution, a dynamic operating system was constructed by setting up an inclined pallet placement rack, a releasable stop mechanism, and a mobile operating platform integrating spraying, collection, and triggering functions. This design integrates traditional, dispersed fixed operating points (fixed nozzles, fixed harvesting positions) onto a mobile platform, fundamentally resolving the contradiction between "planting density" and "operating space" within the container. While ensuring high-density planting, it creates a centralized, safe, and efficient dynamic workstation for operators, significantly reducing labor intensity and improving operational efficiency and system integration.

[0009] As a preferred embodiment of the present invention, the material receiving part includes a liftable platform, on which a pallet is detachably provided. The pallet includes a base plate and a buffer baffle. The base plate is arranged parallel to the pallet, and the buffer baffle is connected to the base plate to absorb the impact of the pallet slipping.

[0010] Through the above technical solutions, the design of the liftable platform and detachable pallets allows the mobile operating platform to quickly switch between "spraying mode" and "collection mode," achieving multi-functional reuse of a single platform. The buffer baffle effectively absorbs the impact energy of the pallet slipping, preventing the pallet from being damaged or the forage from scattering due to collision, ensuring the stability of the harvesting process and the integrity of the materials.

[0011] As a preferred embodiment of the present invention, a universal guide wheel is further provided on the base plate, and the top of the universal guide wheel is flush with the end face of the base plate.

[0012] With the above technical solution, the top of the omnidirectional guide wheels on the base plate is flush with the end face of the base plate, allowing the pallet to be turned and moved on the base plate with extremely low effort. This greatly optimizes the human-machine collaborative operation experience. Operators do not need to carry the pallet with great effort; they can simply push it to position and transfer it, further reducing labor intensity and improving the smoothness of collaborative operations.

[0013] As a preferred embodiment of the present invention, the material stacking section includes a lifting frame and a stacking plate disposed on the lifting frame, wherein the stacking plate and the pallet are distributed and disposed on the mobile work platform along the moving direction of the mobile work platform.

[0014] Through the above technical solution, the material stacking section and the material receiving section are distributed along the platform's movement direction, forming a clear "receiving-transfer-stacking" assembly line layout. This layout optimizes the space utilization and operational flow on the platform, making the harvesting operation process streamlined and orderly, avoiding operational chaos, and improving overall harvesting efficiency.

[0015] As a preferred embodiment of the present invention, two sets of pallet placement racks are provided, respectively arranged on both sides of the container body width direction, and the mobile operating platform is arranged between the two sets of pallet placement racks.

[0016] By employing the aforementioned technical solution, two sets of pallet racks are placed on either side of the container, with a mobile operating platform positioned in the middle, forming a symmetrical and compact "channel-style operating layout." This layout allows a single mobile operating platform to efficiently serve the planting areas on both sides, maximizing the use of the container's width and achieving maximum space and equipment utilization.

[0017] As a preferred embodiment of the present invention, the mobile work platform includes a base, a drive wheel is provided at the bottom of the base, a lifting motor is also provided on the base, the lifting motor is connected to the lifting slider via a lead screw, a guide rail is also provided on the base, and the slider can move up and down on the guide rail; the lifting platform is fixedly connected to the lifting slider, and the movement of the lifting slider can drive the lifting platform to move.

[0018] The above technical solution utilizes a precision lifting mechanism composed of a lead screw, slider, guide rail, and lifting motor to drive the lifting platform. This structure offers smooth transmission, accurate positioning, and good self-locking, ensuring the stability of the spray components or material receiving parts during lifting and stopping, thus guaranteeing the accuracy and reliability of the operation.

[0019] As a preferred embodiment of the present invention, the spray assembly includes a water tank, a conduit, and a nozzle, wherein the nozzle is detachably mounted on the liftable platform; and the water tank is mounted on the base.

[0020] The above technical solution fully integrates the spraying components (water tank, conduit, and nozzles) onto the mobile operating platform, completely eliminating the need for a complex network of fixed pipes inside the container. This not only simplifies installation and reduces costs but also frees up overhead space and avoids interference from pipes with lighting and personnel operations, making the system simpler and more reliable.

[0021] As a preferred embodiment of the present invention, the triggering mechanism and the stop mechanism are triggered by mechanical triggering or electromagnetic control.

[0022] The above technical solutions offer two triggering methods: mechanical and electromagnetic control, increasing the system's flexibility and adaptability. Purely mechanical triggering offers high reliability, simple maintenance, and low cost, making it particularly suitable for harsh environments; electromagnetic control provides precise control and rapid response, facilitating deep integration with intelligent systems. This provides an optimal solution for users with different needs.

[0023] As a preferred embodiment of the present invention, the stop mechanism includes a stop fixed to the pallet placement frame; a movable block slidably disposed on the pallet placement frame; an inclined groove is provided on the movable block; and a connecting rod is fixed on the stop, the connecting rod passing through the inclined groove. When the moving block slides, the stop block is driven to move through the cooperation of the inclined groove and the connecting rod, thereby removing the obstruction to the hay tray.

[0024] The above technical solution, employing a slant-linkage transmission mechanism, utilizes simple mechanical principles to achieve the conversion of motion direction and the transmission of force. The structure is compact, ingenious, and reliable. This purely mechanical structure requires no electricity, fundamentally avoiding potential electrical component failures in humid environments and ensuring long-term stable operation of the system in agricultural settings.

[0025] This invention also discloses a containerized forage cultivation method based on mobile operations, applied to any of the systems described above, comprising the following steps: S1. Cultivation Operation Stage: The central controller, based on environmental parameters or a preset program, instructs the multi-functional mobile operation platform to move along the track and activates the spraying device of its self-contained operation unit to perform mobile precision spraying on the forage on the pallet placement rack. S2. Harvesting preparation stage: The central controller instructs the multi-functional mobile operation platform to move to the designated loading position inside the container and replace the nozzles on the lifting platform with material receiving parts; S3. Automated collection and human collaboration phase: S31. The mobile work platform is moved to a position below the target pallet rack and precisely positioned. S32. Trigger the release of the stop mechanism of the corresponding bracket; S33. The pallet carrying mature hay slides down the pallet placement frame under the action of gravity onto the material receiving part of the mobile operation platform; S34. Rotate and adjust the position of the pallet on the material receiving part, and stack it in the stacking area of ​​the mobile operation platform; S4. Circulation and Transfer Phase: Repeat step S3 until the stacking area of ​​the mobile work platform is fully loaded. Then the platform moves automatically or under control to the unloading point at the container exit, where the batch of pallets are unloaded by operators or external equipment.

[0026] The above technical solution provides an operational method of "mobile spraying - preparation for changing - automatic triggering of sliding - human-machine collaborative stacking - cyclic transfer". This method perfectly combines the high efficiency of automated equipment with the flexibility of human labor, freeing workers from heavy handling work and allowing them to focus only on the lightest turning and stacking operations, thus realizing a safe, efficient, and humanized industrialized harvesting process within limited space.

[0027] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention, through its unique collaborative design of "mobile operating platform + tilting pallet rack + gravity sliding," dynamically integrates dispersed and fixed work points onto a single mobile platform. This allows operators to complete spraying and harvesting of all pallets from a spacious "dynamic workstation" (i.e., the mobile operating platform) without having to enter cramped aisle areas, maintaining extremely high planting density while creating a safe, efficient, and user-friendly operating environment.

[0028] 2. This invention highly integrates multiple functions such as spraying, triggering, receiving, and stacking into a single mobile operating platform, achieving "one machine for multiple uses." During the harvesting process, the system handles the most demanding tasks, including movement and positioning, stop triggering, pallet receiving, and automatic stacking surface maintenance, while manual labor is limited to light pallet turning and pushing. This "machine-led, human-assisted" human-machine collaborative mode not only frees workers from high-intensity physical labor but also streamlines and standardizes the harvesting process, significantly improving the consistency of operational efficiency and reducing reliance on skilled workers.

[0029] 3. This invention employs a simple and reliable mechanical structure, ensuring the system's stability and economy in complex agricultural environments. Core mechanisms such as the stop mechanism based on inclined groove-linkage transmission, the low-friction transfer design utilizing casters, and the scissor-type or screw-type lifting and stacking mechanisms all utilize purely mechanical principles, resulting in a compact structure and reliable operation. This design avoids reliance on numerous sensors and complex electronic control systems, reducing manufacturing costs and post-maintenance complexity. It is particularly suitable for the humid and dusty conditions inside containers, ensuring long-term stable and low-cost operation of the system, and possesses extremely high commercialization value.

[0037] The following is in conjunction with the appendix Figure 1-6 The present invention will be described in further detail below.

[0038] Example 1: Reference Figures 1-6 This embodiment discloses a containerized forage cultivation system based on mobile operations, including a container body 1. The container body 1 is equipped with a shelving system, a ventilation system, a lighting system, and an intelligent control system. The interior of the container body 1 is provided with an insulation layer, a moisture-proof layer, and an anti-corrosion coating. A sealed door is opened on one side of the container body 1 (not shown in the figure; the opening of the container body 1 in the figure represents one side of the sealed door) for personnel access and maintenance.

[0039] The racking system includes pallet racks 2. In this embodiment, there are two sets of pallet racks 2, which are respectively set on both sides of the width direction of the container body 1. The two sets of pallet racks 2 are symmetrically distributed, and there is a gap between the two sets of pallet racks 2. A mobile work platform 3 is set in this gap. The width of the mobile work platform 3 is about the same as the width of the gap, and the mobile work platform 3 can move along the length direction of the gap to perform operations. Guide rails can be laid along the length direction of the gap, and the mobile work platform 3 can move along the guide rails to ensure accurate movement.

[0040] The pallet rack 2 is used to carry pallets 4 for hay. Each set of pallet racks 2 has multiple layers in the height direction, generally 4-7 layers (3 layers in the figure for schematic diagram). Each layer of pallet rack 2 has pallets 4 evenly placed on it, and each layer of pallet rack 2 has only one pallet 4 in the width direction. The pallet rack 2 is inclined, and the pallet rack 2 is set with an inclination angle that makes the pallet 4 have a downward tendency under the action of gravity. Specifically, the pallet rack 2 near the middle of the container body 1 is lower in height. Under no resistance, the pallet 4 will slide to the middle of the container body 1, that is, the gap between the two sets of pallet racks 2. A stop mechanism 5 is provided at the end of the pallet rack 2. The stop mechanism 5 has a locking state to prevent the pallet 4 from sliding and a releasing state to allow the pallet 4 to slide.

[0041] The stop mechanism 5 includes a stop 502 and a moving block 501. Its core feature is that the stop 502 is raised and lowered through an embedded inclined groove transmission structure.

[0042] Specifically, the stop block 502 has a frame structure with a hollow portion 504 in its middle. A connecting rod 505 is horizontally and fixedly connected to both sides of the frame of the stop block 502 and spans the hollow portion 504.

[0043] The movable block 501 is slidably disposed on the tray frame 2 and is at least partially located within the hollow portion 504 of the stop block 502. A sloping groove 503 is formed on the side or inside of the movable block 501 along its sliding direction. The connecting rod 505 of the stop block 502 passes through this sloping groove 503.

[0044] When the multi-functional mobile work platform moves to a predetermined position and contacts and pushes the moving block 501, the moving block 501 is displaced along its sliding direction (e.g., horizontal direction). Since the connecting rod 505 passes through the inclined groove 503, the linear movement of the moving block 501 forces the inclined wall of the inclined groove 503 to move relative to the connecting rod 505, thereby converting the horizontal thrust of the moving block 501 into a component force on the connecting rod 505 perpendicular to the sliding direction (e.g., vertical direction). This component force drives the connecting rod 505 and causes the entire stop 502 to move vertically, thus achieving the lowering (unlocked state) or raising (locked state) of the stop 502. This mechanism is compact, reliable, and uses purely mechanical transmission without the need for electricity or complex control, making it particularly suitable for humid and dusty working environments inside containers.

[0045] The pallet 4 is a rectangular structure. In this embodiment, the long rectangular side of the pallet 4 is set in the width direction of the container body 1, which maximizes the number of pallets 4 in a single layer. At the same time, it also minimizes the gap between the two sets of pallet racks 2, thereby improving space utilization.

[0046] A grid structure (not shown in the figure) is set inside the tray 4, which divides the interior of the tray 4 into multiple spaces, each of which is used to place pasture seeds, such as barley grass seeds.

[0047] A lighting system is installed on the tray placement rack 2 to provide supplemental light for the planted forage grass. At different growth stages, the system can adjust the spectral ratio of the LEDs (such as increasing blue light during the growth period to promote robust plant growth, and increasing red light during the maturity period to promote biomass accumulation) and the light intensity.

[0048] Data acquisition systems are installed in various areas within container 1, including temperature and humidity sensors, CO2 concentration sensors, and cameras. Temperature and humidity sensors are evenly distributed across the upper, middle, and lower sections of container 1 to monitor ambient temperature and humidity in real time, preventing the formation of localized hotspots or areas with excessively high humidity.

[0049] A CO2 concentration sensor monitors the CO2 content inside the chamber. A camera is used to acquire images for machine vision analysis. By periodically capturing images of the pasture, AI algorithms can analyze growth indicators such as average height, leaf color (greenness), and density, thereby intelligently determining the growth stage and health status, providing visual basis for adjusting light, water, and air strategies.

[0050] The sprinkler assembly 6 is responsible for precisely supplying water and nutrients. To reduce the need for laying sprinkler irrigation pipes within the container body 1, in this embodiment, the sprinkler system is integrated into the mobile operating platform 3. The mobile operating platform 3 includes a base 301, with drive wheels 302 at the bottom of the base 301. The drive wheels 302 are driven by a drive motor (not shown in the figure) to move. A lifting motor 303 is also provided on the base 302, and the lifting motor 303 is connected to a lifting slider 305 via a lead screw 304. A guide rail 306 is also provided on the base 301, and the lifting slider 305 can move up and down on the guide rail 306. When the lifting motor 303 is activated, it drives the lead screw 304 to rotate, thereby moving the lifting slider 305 up and down. The lifting platform 307 is fixedly connected to the lifting slider 305, so the movement of the lifting slider 305 can move the lifting platform 307 up and down.

[0051] The sprinkler assembly 6 includes a water tank 601, a conduit 602, and a nozzle 603. The nozzle 603 is detachably mounted on the liftable platform 307; the water tank 601 is mounted on the base 301. The water tank 601 is connected to the nozzle 603 via the conduit 602 to spray water onto the nozzle 603. During the forage cultivation stage, the nozzle 603 is mounted on the liftable platform 307, and the liftable platform 307 moves the nozzle 603 vertically to spray water onto the trays 4 at different heights. Simultaneously, the drive wheels 302 move the base 301 to spray water onto each tray 4 along the length of the container body 1, thus achieving precise sprinkler irrigation.

[0052] A liquid filling port is also provided on the water tank 601. A liquid filling station can be set up at the sealed door on one side of the container body 1 along the length direction to replenish the water tank 601.

[0053] The mobile operating platform 3 is also equipped with a material receiving section for receiving hay pallets that slide down from the pallet placement rack, and a material stacking section for stacking the pallets received by the material receiving section. When the hay reaches maturity and needs to be harvested, harvesting can be carried out manually in conjunction with the mobile operating platform 3, which can greatly improve harvesting efficiency and reduce labor.

[0054] Harvesting with the assistance of the mobile work platform 3 first requires replacing the nozzles 603 on the lifting platform 307 with pallets 7. The pallets 7 are fixed to the lifting platform 307 in a detachable manner (such as by pins or buckles) and serve as a material receiving part to receive the slipping hay trays 4.

[0055] The pallet 7 includes a base plate 701 and a buffer baffle 703 vertically fixed to one end thereon. Multiple casters 702 are provided on the upper surface of the base plate 701, with the tops of the casters 702 flush with or slightly lower than the upper surface of the base plate 701 to ensure that the pallet 4 can slide smoothly without wobbling. The buffer baffle 703 is used to absorb and cushion the impact force when the pallet 4 slides down.

[0056] During harvesting, the central controller instructs the mobile work platform 3 to move to and precisely position itself below the target pallet placement rack 2. The platform continues to make slight movements, causing its trigger mechanism to contact and push the moving block 501 of the stop mechanism 5. In this embodiment, the trigger mechanism is a trigger push block 10, which is fixed to the side of the base plate 701 by screws.

[0057] The sliding block 501, through the cooperation of its inclined groove 503 and the connecting rod 505 on the stop block 502, converts the horizontal thrust into a vertical component force, driving the stop block 502 to descend and release the obstruction to the pallet 4. The pallet 4 carrying mature hay then slides down the inclined pallet placement frame 2 under the action of gravity, and finally hits the buffer baffle 703 of the pallet plate 7, and comes to a stable stop on the base plate 701.

[0058] Subsequently, the operator turns the pallet 4, which has slid down onto the pallet 7, 90 degrees and uses the universal guide wheels 702 on the base plate 701 to easily pull the pallet 4 laterally onto the stacking plate 801 of the material stacking section 8.

[0059] The material stacking section 8 is the core component for automated stacking, and its specific structure is as follows: It includes a drive cylinder 806 fixed to the base 301 of the mobile operating platform 3 and a guide seat 804 fixed to the base 301. The guide seat 804 has a sliding groove 805. The drive cylinder 806 is connected to a sliding rod 808, which can slide within the sliding groove 805. First forks 807 are hinged to both ends of the sliding rod 808, and the other end of the first forks 807 is hinged to the lifting platform 802. Second forks 803 are slidably connected to both ends of the lifting platform 802, and the other end of the second forks 803 is hinged to the guide seat 804. Stacking plates 801 are installed on the lifting platform 802.

[0060] By driving the cylinder 806 to move, the slide bar 808 slides in the slide groove 805, thereby changing the angle between the first fork 807 and the second fork 803, which in turn drives the lifting platform 802 to move up and down in the height direction.

[0061] When the first pallet 4 is manually pushed onto the stacking plate 801, the control system will instruct the lifting motor 805 to move, driving the lead screw 802 to rotate at a certain angle, so that the stacking plate 801 is lowered by a distance slightly less than the height of the pallet (for example, lowering the pallet by 90% of its thickness).

[0062] Subsequently, the lifting platform 307 of the mobile operating platform 3 lowers the pallet 7 to a height similar to the upper surface of the current stacked pallet 801, ready to receive the next pallet 4. The above harvesting steps are repeated, placing the second pallet 4 on top of the first pallet. This cycle continues, with the stacked pallet 801 gradually lowered under the instructions of the control system, always maintaining the stacking surface at the height most convenient for manual operation. This "receive-place-lower" cycle allows operators to complete all stacking actions without bending over or raising their hands, greatly reducing labor intensity and ensuring the neatness and stability of the stack.

[0063] Once all pallets on the same level have been collected and stacked, the mobile operating platform 3 adjusts its longitudinal position via its walking mechanism and adjusts the vertical height of the pallet 7 via the lifting platform 307, aligning it with the pallet placement rack 2 on the next level to be collected, and continues the above collection process. This flexible positioning capability in three-dimensional space enables a single mobile operating platform 3 to efficiently serve pallets on all levels within the container.

[0064] Repeat the above steps until the stacked pallets 801 are fully loaded. Then, the mobile work platform 3 moves to the unloading point at the container exit, where workers or external equipment unload the entire batch of pallets 4, completing the harvesting operation.

[0065] Example 2: This embodiment describes in detail a containerized forage cultivation method based on mobile operations. This method is applied to the system described in Embodiment 1 and specifically includes the following steps: S1, Cultivation and Training Stage: The central controller generates a spraying command based on a preset light cycle or environmental parameters monitored in real time by sensor components (such as low local humidity). The command instructs the mobile work platform 3 to move along a preset track to the target area. Subsequently, its spraying assembly 6 is activated: the lifting motor 303 actuates, driving the lifting slider 305 to rise and fall along the guide rail 306 via the lead screw 304, thereby adjusting the lifting platform 307, equipped with sprinkler heads 603, to the height corresponding to the target tray 4. Nutrient solution from the water tank 601 is sprayed from the sprinkler heads 603 through the conduit 602, providing mobile and precise spraying irrigation for the hay on the tray placement rack 2.

[0066] S2. Harvesting Preparation Stage: Once the system identifies that the forage has reached the harvest standard via the camera, the central controller instructs the mobile work platform 3 to move to the designated loading position inside the container (usually near the refueling station). The operator removes the nozzles 603 from the lifting platform 307 and replaces them with the pallet 7, which serves as the material receiving unit. The pallet 7 is quickly secured to the lifting platform 307 using pins or clips, and its base plate 701 is equipped with omnidirectional guide wheels 702 and buffer baffles 703.

[0067] S3. Automated collection and human collaboration phase: S31. Positioning: The central controller instructs the mobile work platform 3 to move below the target pallet placement rack 2, and achieves precise positioning through track coding or position sensors to ensure that the trigger push block 10 on the platform is aligned with the moving block 501 of the stop mechanism 5.

[0068] S32. Trigger Release: The mobile work platform 3 continues to move slightly, and the trigger push block 10 on it contacts and pushes the moving block 501 to slide horizontally. The inclined groove 503 on the moving block 501 and the connecting rod 505 fixed on the stop block 502 generate relative movement, converting the horizontal thrust into a vertical component force, driving the stop block 502 to descend, thereby releasing the obstruction to the hay tray 4.

[0069] S33. Sliding and receiving: The pallet 4 carrying mature hay slides down the inclined pallet placement frame 2 under the action of gravity, and finally hits the buffer baffle 703 of the pallet 7 smoothly and stops on the bottom plate 701.

[0070] S34. Steering and stacking: Using the extremely low friction provided by the universal guide wheel 702, the operator can easily rotate the pallet 4 about 90 degrees on the base plate 701 and then push it laterally onto the stacking plate 801 of the material stacking section 8.

[0071] S4. Cyclic and Hierarchical Adjustment Phase: S41. Automatic stacking: When the first pallet 4 is placed on the stacking plate 801, the control system commands the cylinder 806 to move, causing the slide bar 808 to slide in the slide groove 805, thereby causing the scissor lifting mechanism composed of the first fork 807 and the second fork 803 to retract, driving the lifting platform 802 and the stacking plate 801 to descend a distance slightly less than the height of the pallet.

[0072] S42. Adjustment and docking: Subsequently, the lifting motor 303 is activated, driving the lifting platform 307 and pallet 7 to descend, so that the height of the base plate 701 is flush with the upper surface of the descended stacking plate 801, ready to receive the next pallet 4. Repeat steps S31 to S34 until all pallets at the current storage location on this layer have been received.

[0073] S43. Layer change operation: The mobile work platform 3 adjusts its longitudinal position through the drive wheel 302 and adjusts the vertical height of the pallet 7 through the lifting platform 307, accurately aligning it with the pallet placement rack 2 to be harvested on the next layer. Repeat steps S3 and S4 to achieve continuous and efficient harvesting in three-dimensional space.

[0074] S5. Transshipment Stage: Once the pallets on the material stacking section 8 are fully loaded, the mobile work platform 3 automatically moves to the unloading point at the container exit. Operators or external equipment unload the entire batch of pallets 4, completing the harvesting operation.
