Description

Technical Field

[0001] This invention relates to the field of garden waste treatment technology, and in particular to a distributed automatic collection system for garden green waste and its working method, which belongs to the technical direction of cross-application of green environmental protection, solid waste management and automatic control system. Background Technology

[0002] Landscape greening plays a vital role in urban infrastructure and ecosystems, generating a large amount of green waste during its daily maintenance. This waste mainly includes biological materials such as branches, fallen leaves, grass clippings, and shrub pruning residues, characterized by large volume, low density, high moisture content, and dispersed sources. With the continuous increase in urban green coverage, the amount of landscape green waste is constantly growing, placing higher demands on the efficiency and intelligence of collection and treatment systems.

[0003] Current methods for collecting and treating garden waste primarily rely on manual collection, vehicle transportation, and centralized crushing. These methods generally suffer from high labor costs, low processing efficiency, and significant environmental pollution risks. While some cities have introduced vehicle-mounted crushing equipment to reduce the volume of waste, manual transport of the waste to the vehicles for processing remains necessary, resulting in high labor intensity and limited collection efficiency. Furthermore, waste is prone to scattering during transportation, leading to road pollution, pest infestations, and increased costs for secondary cleanup.

[0004] Some research institutions and companies have attempted to introduce negative pressure adsorption or pipeline transportation systems, already used in municipal solid waste, into the green waste collection process. However, due to the irregular physical form, wide range of branch lengths, and high moisture content of garden green waste, directly applying existing waste adsorption technologies often fails to meet actual operational needs, easily leading to problems such as pipeline blockage, shredder damage, or insufficient suction. At the same time, existing green waste collection systems lack unified solutions in terms of structural layout, intelligent monitoring, and energy management, making them difficult to adapt to the widely distributed and frequently collected garden scenarios. Overall operational stability and automation levels still have significant room for improvement.

[0005] Therefore, there is an urgent need to provide an automatic green waste collection system that is suitable for garden settings, has negative pressure adsorption capabilities, can take into account both crushing and diversion mechanisms, and has the ability to monitor accumulation and intelligent control, so as to improve the efficiency, safety and intelligence level of garden green waste collection. Summary of the Invention

[0006] This invention aims to address the problems of heavy manual labor, low crushing and conveying efficiency, and poor adaptability in existing garden waste collection methods. It proposes a distributed automatic garden waste collection system and working method. By constructing an automated collaborative structure consisting of a sealed collection chamber, adsorption pipes, a crushing device, and an adsorption head, it achieves efficient adsorption, coarse crushing, and centralized collection of green waste in different forms. At the same time, by combining image recognition and intelligent push control, it improves the system's operational intelligence, deployment flexibility, and overall processing efficiency.

[0007] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: A distributed automated collection system for garden waste includes: The sealed collection room has a sealed collection space inside for storing green waste. The sealed collection space is equipped with a visual camera for monitoring the accumulation of green waste. The bottom of the sealed collection space is equipped with a tracked pushing device for pushing the green waste to move in a predetermined direction to discharge the green waste and prevent it from accumulating in a fixed area. The adsorption pipe is connected at one end to the sealed collection chamber and at the other end to the adsorption head, and is used to adsorb garden waste in a negative pressure manner through the negative pressure device set in the sealed collection chamber. A pulverizing device, connected between the adsorption pipe and the adsorption head, is used to pulverize the green waste in the adsorption path. The pulverizing device includes: One main channel is used to receive green waste in the adsorption path; A pulverizing chamber is located in the main channel and is used to process medium-heavy green waste such as branches; A bypass passage, located above the main passage, is used to allow lightweight green waste such as grass clippings and leaves to bypass the crushing chamber and enter the sealed collection chamber directly; The adsorption path connection method of the system includes two types: When the adsorption point is close to the sealed collection chamber, the adsorption head is connected to the pulverizing device, and the pulverizing device is connected to the adsorption pipe; When the adsorption point is far apart, the adsorption head is connected to an extension pipe, the extension pipe is connected to the pulverizing module, and the pulverizing device is connected to the adsorption pipe; wherein... The system integrates the pulverizing device into the adsorption path, achieving integrated control of the adsorption, pulverizing, and conveying processes. The sealed collection chamber is equipped with the tracked pushing device and the vision camera, and a visual perception and accumulation distribution adjustment linkage mechanism is constructed to realize intelligent spatial management of indoor accumulated green waste. The adsorption path has a distance adaptive configuration structure, which can select two path modes according to the distance between the adsorption point and the chamber, enhancing the system's deployment scenario adaptability and module compatibility.

[0008] Optionally, the inlet of the adsorption head is provided with an isolation net. The mesh size of the isolation net is designed to allow leaves or ordinary branches to pass through while blocking large branches that exceed a preset size, so as to prevent clogging of the adsorption pipe or damage to the crushing device.

[0009] Optionally, the sealed collection space is provided with an opening structure at the position corresponding to the tracked pushing device. The opening structure gradually narrows outward to guide the green waste to be discharged smoothly and to avoid obstruction in the corner area.

[0010] Optionally, the crushing device is a coarse crushing mechanism that only performs non-fine crushing treatment on green waste, in order to improve processing efficiency and reduce system cost and energy consumption.

[0011] Optionally, the visual camera captures images within the sealed collection space and performs real-time analysis to determine the green waste accumulation capacity. When the accumulation capacity reaches a preset percentage threshold, a prompt message is sent to the management terminal to prompt the green waste removal operation.

[0012] Optionally, the visual camera, the tracked conveyor, the crushing device, and the adsorption head are all communicatively connected to the system control module to acquire the operating status and working parameters of each device in real time.

[0013] Optionally, the adsorption head can be connected to the outer shell of the crushing device for charging via an overlap, or it can be powered by the crushing device via a power cord; the bottom of the crushing device is provided with an automatic charging interface, which can automatically recharge when the power is lower than the threshold and return to the charging area of ​​the sealed collection chamber.

[0014] Optionally, the adsorption head is equipped with an independent negative pressure generating device to form a local negative pressure adsorption force at the inlet of the adsorption head. The local negative pressure works in conjunction with the negative pressure device in the sealed collection chamber to improve the green waste collection efficiency under long-distance or high-resistance adsorption conditions.

[0015] Optionally, the adsorption pipe, the extension pipe, the adsorption head, and the crushing device all adopt a quick-connect structure. The connection structure includes a sealing flange, a quick-release buckle, and a positioning limit block to facilitate quick disassembly and module replacement.

[0016] To achieve the above-mentioned technical objectives, the present invention also adopts the following technical solution: A method for operating a distributed automatic collection system for garden waste, applicable to any of the systems described above, comprising the following steps: Step 1: Activate the negative pressure device installed inside the sealed collection chamber to create a negative pressure airflow along the adsorption pipe; select the adsorption path connection method according to the distance between the adsorption point and the sealed collection chamber: If the distance is close, connect the adsorption head to the crushing device, which is connected to the adsorption pipe. If the distance is far, connect the adsorption head to the extension pipe, the extension pipe to the crushing device, and the crushing device to the adsorption pipe. Step 2: Adsorb green waste in the garden area through the adsorption head. The isolation net at the entrance of the adsorption head blocks large branches and allows ordinary branches and leaves to pass through. When the adsorption head has an independent negative pressure generating device, the device is activated to work in conjunction with the negative pressure of the chamber to enhance the adsorption force. Step 3: Green waste in the adsorption path enters the crushing device; medium and heavy green waste such as branches enter the crushing chamber through the main channel for coarse crushing; light green waste such as grass clippings and leaves bypass the crushing chamber through the bypass channel located above the main channel and directly enter the sealed collection chamber; Step 4: The shredded or bypassed green waste enters the sealed collection space; the system collects images and analyzes the accumulation volume through a vision camera installed in the sealed collection space; when the accumulation volume reaches a preset threshold (e.g., 70%), the system sends a prompt message to the administrator terminal; Step 5: The tracked pushing device starts operation according to the image recognition results, pushing the green waste along the set direction to the opening of the chamber; the opening structure has an externally gradually narrowing guide shape at the track outlet position to assist the discharge of green waste and avoid jamming. Step 6: When the crushing device or adsorption head is in battery-powered mode, if the detected power level is lower than the preset threshold, the crushing device will return to the location of the sealed collection chamber along the preset trajectory and be recharged through the automatic docking device.

[0017] The main advantages of the in-situ calibration device and method for level gauges of the present invention compared to the prior art are as follows: This invention constructs a collaborative system consisting of a sealed collection chamber, a negative pressure adsorption pipeline, a crushing device, and an adsorption head. This system replaces the traditional treatment method that relies on manual handling and single-point crushing, enabling automated and continuous operation of garden waste from collection to transmission. It significantly reduces the intensity of manual intervention, improves system operating efficiency and safety, and overcomes the problems of low collection efficiency and lack of connection between treatment links in the existing technology.

[0018] The system of the present invention, by setting up a structural combination of main channel, crushing chamber and bypass channel, allows light green waste such as grass clippings and fallen leaves to bypass the crushing chamber and directly enter the collection chamber, while only medium and heavy branches are coarsely crushed. This effectively avoids the risk of equipment blockage and overload caused by the complex properties of materials, while improving the system's throughput and economy.

[0019] This invention, by installing a visual camera and a tracked pushing device inside the sealed collection chamber, allows the system to monitor the accumulation status of green waste in real time and coordinate with the pushing device to perform directional distribution and pre-emptive cleaning, thus avoiding the problems of wasted storage space and poor unloading caused by uneven material accumulation in traditional structures.

[0020] The system of the present invention has the ability to configure the adsorption path based on distance adaptation. It can flexibly choose whether to connect via the crushing module according to the distance between the adsorption point and the chamber. This facilitates the flexible deployment of multiple collection nodes in large-scale, multi-point distribution areas such as urban green spaces and parks, effectively improving the system's adaptability to complex garden terrain and explosive distribution of green waste.

[0021] The key components of this invention, such as the visual camera, track pushing device, crushing module, and adsorption head, are all connected to the system control module, supporting green waste capacity threshold monitoring, operation status feedback, and remote alarm prompts. This provides real-time decision-making basis for green waste treatment operation and maintenance, and improves the overall intelligent operation capability and management efficiency of the system. Attached Figure Description

[0022] Figure 1 This is a schematic diagram of the overall structure of the automatic green waste collection system of the present invention; Figure 2 This is a flowchart illustrating the steps of the automatic green waste collection system of the present invention. Detailed Implementation

[0023] The following detailed description, in conjunction with the accompanying drawings, illustrates the distributed automatic collection system for green waste in gardens and the working method described in this invention. This embodiment uses typical garden scenarios (residential green spaces, urban parks, etc.) as its application background, focusing on the device structure and workflow defined in the claims. Its purpose is to clearly illustrate the specific implementation methods of this invention, rather than limiting the scope of protection of this invention. All equivalent improvements, substitutions, or extensions made based on the core technical concept of this invention should be included within the scope of protection of this invention.

[0024] The core objective of this invention is to solve the problems of existing garden waste collection, such as reliance on manual labor, low efficiency, and poor adaptability. By constructing an automated system in which a sealed collection chamber, adsorption pipes, crushing device, and adsorption head work together, combined with an intelligent monitoring and control mechanism, it achieves efficient collection, diversion and crushing, centralized storage, and intelligent operation and maintenance of distributed garden waste. It is suitable for the treatment needs of different distances and types of green waste, and is especially applicable to garden scenarios where green waste sources are dispersed and collection frequency is high.

[0025] like Figure 1As shown, the distributed automatic collection system for garden waste described in this embodiment mainly consists of four core components: a sealed collection chamber, adsorption pipes, a crushing device, and an adsorption head, supplemented by auxiliary components such as a system control module and a power supply unit. Each component is detachably connected via a quick-assembly structure, enabling modular assembly and flexible deployment, forming an integrated operation process of "green waste collection - diversion and crushing - negative pressure conveying - centralized storage - intelligent monitoring". The structural design and functional implementation of each core component strictly correspond to the technical features defined in the claims, as detailed below: Sealed collection chamber 1 The sealed collection chamber serves as the core carrier for centralized storage of green waste, negative pressure generation, and system control. Its sealed structure ensures excellent airtightness, guaranteeing stable negative pressure adsorption. Considering the space requirements and green waste generation volume of typical application scenarios such as residential green spaces, the chamber's dimensions are optimally set at 2.5m (length) × 1.8m (width) × 2.2m (height). This compact structure allows for flexible placement in unused areas such as corners of residential communities and park edges, without occupying significant activity space. The outer shell is constructed of corrosion-resistant, high-strength materials, with an internal seal to prevent air leakage during negative pressure operation. This also effectively isolates odors generated during green waste storage, preventing environmental impact.

[0026] The interior of the chamber forms a sealed collection space for the temporary storage of green waste after adsorption and pulverization. To enable real-time monitoring and intelligent management of the green waste accumulation, a visual camera is installed within the sealed collection space. This camera is mounted on the inner top of the chamber, covering the entire sealed collection space with no blind spots. It can collect real-time images of the accumulated green waste and transmit the image data to the system control module. The core function of the visual camera is to monitor the height, range, and volume of the accumulated green waste, providing data support for subsequent removal reminders and the activation of the tracked moving device. This ensures the rational use of the chamber's storage space and prevents excessive or uneven accumulation of green waste.

[0027] The bottom of the sealed collection space is equipped with a tracked pushing device. This device is arranged along the length of the chamber and can move back and forth along a preset trajectory. Its core function is to push the green waste in a predetermined direction (towards the chamber's exit). This prevents the green waste from accumulating and clumping in fixed areas inside the chamber, ensuring even use of the storage space. It also assists in the smooth discharge of green waste, preventing it from getting stuck at the exit. The tracked pushing device uses a wear-resistant track structure and has strong thrust. It can adapt to the pushing needs of different humidity levels and different types of green waste. Its operation is automatically controlled by the system control module based on the accumulation data collected by the visual camera, achieving intelligent linkage of the pushing operation.

[0028] The sealed collection chamber has an interface connected to the adsorption pipeline. This interface is located on the upper side of the chamber and runs through the internal sealed collection space to receive the green waste transported via the adsorption pipeline. The chamber also contains a negative pressure device connected to the adsorption pipeline interface. During operation, this device creates a stable negative pressure environment within the sealed collection space and the adsorption pipeline, providing the power source for the adsorption and transport of green waste. The negative pressure intensity of the device can be adaptively adjusted according to the adsorption distance and the type of green waste, ensuring stable adsorption effects for both short-distance and long-distance adsorption.

[0029] The sealed collection space has an opening at the end of the tracked conveyor, serving as a waste discharge channel. The opening's dimensions are matched to the width of the tracked conveyor, ensuring the waste pushed by the conveyor can smoothly enter the opening. To further optimize waste discharge and prevent blockage at the opening's corners, the opening gradually narrows outwards, guiding the waste through a flow-guiding design to improve collection efficiency. An openable, sealed door can be installed at the opening. This door remains closed during non-collection periods to ensure the enclosure's airtightness; it opens during collection to facilitate waste discharge to the collection equipment.

[0030] In addition, the sealed collection chamber also integrates the installation area for the system control module. The control module establishes communication connections with the vision camera, tracked conveyor, and negative pressure device, enabling it to receive real-time operational status data from each device and send control commands, achieving centralized control and intelligent linkage of the entire system. The overall noise level during operation is controlled to ≤75dB, meeting the noise and environmental protection requirements for residential areas, parks, and other similar settings, and will not disturb nearby residents or tourists.

[0031] Adsorption pipe 2 The adsorption pipeline serves as the core channel for transporting green waste. One end is detachably connected to the interface of the sealed collection chamber, while the other end is connected to the crushing device or the adsorption head (the connection method is selected according to the adsorption distance). Its core function is to form a channel for transporting green waste under the action of the negative pressure device, and to stably transport the green waste collected by the adsorption head to the sealed collection chamber.

[0032] The adsorption pipeline is made of lightweight, high-strength, and corrosion-resistant materials, possessing excellent sealing and wear resistance, making it suitable for long-term use in outdoor landscaping environments while facilitating transportation and installation. The pipeline's inner diameter has been optimized to ensure smooth passage of green waste (especially coarsely crushed branches) while minimizing negative pressure loss and ensuring effective transmission of negative pressure adsorption force. To allow for flexible deployment and length adjustment, the adsorption pipeline employs a segmented structure, with each segment connected by a quick-connect mechanism. This quick-connect mechanism includes sealing flanges, quick-clamping clips, and positioning limit blocks, enabling rapid disassembly and module replacement. This facilitates adjustment of the total pipeline length based on the distance between the adsorption point and the sealed collection chamber, while also simplifying future maintenance and repair.

[0033] For long-distance adsorption scenarios, the system is also equipped with an extension pipe. The extension pipe has the same structure as the adsorption pipe and is only used to extend the overall conveying distance. Its two ends can be quickly connected to the adsorption head, crushing device, or adsorption pipe, respectively. By combining the adsorption pipe and the extension pipe, the system can flexibly adapt to adsorption needs at different distances, improving its scenario adaptability. After the adsorption pipe and the extension pipe are connected, the entire system remains sealed to ensure the stability of the negative pressure environment and prevent air leakage at the pipe connection points from causing a decrease in adsorption force or obstruction of green waste conveying.

[0034] Crushing device 3 The pulverizing device, connected between the adsorption pipe and the adsorption head, is the core component for the diversion and pulverization of green waste. Its core design philosophy is to provide differentiated treatment for green waste of different textures and types (light green waste and medium-to-heavy green waste), ensuring both pulverization effectiveness and improved processing efficiency while avoiding equipment overload or pipe blockage. The pulverizing device has a compact structure and small size, allowing for flexible deployment at different adsorption points, adapting to the distributed collection needs of residential areas, parks, and other similar settings.

[0035] The crushing device is internally configured with a main channel, a crushing chamber, and a bypass channel, forming a parallel flow channel structure to achieve automatic diversion and differentiated treatment of green waste. The main channel serves as the primary flow path for green waste, connecting at one end to the adsorption head (or extension pipe) to receive the collected green waste, and at the other end to the adsorption pipe to transport the treated green waste to a sealed collection chamber. The crushing chamber is located in the middle of the main channel and contains a coarse crushing mechanism. This mechanism performs non-refined crushing of the green waste, primarily to break down medium-heavy green waste such as branches into suitable particle sizes for subsequent pipeline transport, while also reducing system energy consumption and equipment costs, and avoiding the inefficiency caused by fine crushing. The coarse crushing mechanism employs a rotary cutting structure with strong cutting capabilities, adaptable to the crushing needs of branch-type green waste with diameters not exceeding a preset size. The particle size of the crushed green waste can be controlled through a screen structure inside the crushing chamber to ensure compliance with pipeline transport requirements.

[0036] The bypass channel is located above the main channel, connecting to the inlet and outlet ends of the main channel respectively, forming a diversion channel that bypasses the crushing chamber. Its core function is to allow lightweight green waste such as grass clippings and leaves to directly bypass the crushing chamber and enter the sealed collection chamber without undergoing crushing, thereby improving overall processing efficiency and reducing the ineffective workload of the crushing device. The bypass channel has an airflow guiding structure at its inlet, which automatically diverts the green waste according to its weight and particle size: lightweight green waste enters the bypass channel along the guiding structure under negative pressure airflow; medium and heavy green waste, due to its greater weight, cannot overcome gravity to enter the bypass channel and naturally falls into the main channel and enters the crushing chamber for crushing, achieving automatic classification, processing, and diversion of green waste.

[0037] The pulverizing device adopts a modular design, with quick-connect structures enabling detachable connections to the adsorption head, adsorption pipes, and extension pipes, facilitating rapid assembly, disassembly, and maintenance. Simultaneously, the pulverizing device is equipped with an independent power supply unit, supporting both battery and external power sources to meet the power requirements of various outdoor scenarios. In battery-powered mode, an automatic charging port is located at the bottom of the pulverizing device. When the battery level falls below a preset threshold, it automatically returns to the charging area within the sealed collection chamber along a pre-defined trajectory for recharging, ensuring continuous operation of the equipment.

[0038] Adsorption head 4 As a terminal device for collecting green waste, the adsorption head features a portable design, is compact and lightweight, making it easy for operators to hold or attach to small landscaping equipment. It is suitable for collecting scattered green waste in residential areas, parks, and other similar settings. The inlet end of the adsorption head uses a flared structure to expand the collection range and improve efficiency; the outlet end connects to the crushing device or extension pipe via a quick-connect structure, ensuring a sealed connection and easy assembly / disassembly.

[0039] To prevent large branches exceeding the preset size from entering the adsorption pipes or crushing device, causing blockages or equipment damage, an isolation mesh is installed inside the inlet of the adsorption head. The mesh size of the isolation mesh is optimized to allow leaves, ordinary branches, and other green waste meeting treatment requirements to pass through, while effectively blocking large branches, thus providing filtration and protection. The isolation mesh has a detachable structure, facilitating regular cleaning by operators to remove intercepted large branches and debris, ensuring the normal operation of the adsorption head.

[0040] For long-distance or high-resistance adsorption conditions (such as high humidity, dense accumulation of green waste, or significant negative pressure loss due to long adsorption distance), an independent negative pressure generating device can be added inside the adsorption head. This device works in conjunction with the negative pressure device inside the sealed collection chamber to create a localized negative pressure adsorption force at the inlet of the adsorption head, thereby improving the overall adsorption force and ensuring smooth green waste collection. The operation of the independent negative pressure generating device can be automatically controlled according to the adsorption conditions. It can stop operating during short-distance, low-resistance adsorption to reduce energy consumption, and automatically start during long-distance, high-resistance adsorption to enhance the adsorption effect.

[0041] The power supply for the adsorption head can be achieved by connecting it to the housing of the crushing device via a jacking connection, or by connecting it to the power supply unit of the crushing device via a power cord, ensuring a stable power supply. Simple operation buttons can be installed on the surface of the adsorption head to control its start / stop, the switching on / off of the independent negative pressure generating device, etc., facilitating on-site operation by personnel.

[0042] Auxiliary components and control logic As the core control unit of the entire system, the system control module establishes communication connections with all core devices such as vision camera 5, tracked pushing device 6, crushing device 3, adsorption head 4, and negative pressure device (not shown). It can obtain the operating status parameters of each device in real time (such as negative pressure value, green waste accumulation capacity, equipment power, operating faults, etc.) and send control commands according to preset logic to realize the coordinated work of each device.

[0043] The core control logic of the control module includes: analyzing the green waste accumulation capacity based on image data collected by the vision camera; sending a cleaning reminder to the management terminal when the accumulation capacity reaches a preset threshold; automatically activating the tracked pushing device to push the green waste evenly or towards the outlet based on the green waste accumulation distribution; automatically adjusting the negative pressure intensity of the negative pressure device according to the adsorption distance to ensure stable adsorption effect; monitoring the power status of the crushing device and adsorption head; issuing a charging reminder or controlling the equipment to automatically return to charging when the power is below the threshold; and immediately issuing an alarm message and taking emergency measures such as shutdown and pressure reduction when abnormal conditions such as pipe blockage or equipment failure are detected to ensure safe operation of the system.

[0044] The power supply unit provides stable power support for the entire system. The sealed collection chamber can be connected to the municipal power supply to provide continuous power to the negative pressure device, control module, etc. The crushing device and adsorption head can be powered by batteries, which is convenient for outdoor mobile operation. The battery capacity can be configured according to the working time requirements to ensure that the equipment meets the daily green waste collection endurance requirements.

[0045] like Figure 2As shown in the figure, the working method of the distributed garden waste automatic collection system described in this embodiment is applicable to the system composed of the above-mentioned core devices. This method strictly follows the steps defined in the claims, and through key steps such as path configuration, adsorption and transmission, diversion and crushing, accumulation monitoring, and collection control, it achieves automated collection and treatment of distributed garden waste. The entire workflow requires minimal manual intervention, is highly efficient, and has strong adaptability. The specific working steps are as follows: Step 1: Path Configuration and System Startup Before system startup, the corresponding adsorption path connection method is selected based on the distance between the adsorption point and the sealed collection chamber to achieve adaptive configuration of the adsorption path. Specifically, there are two connection methods: The first method, when the adsorption point is close to the sealed collection chamber (usually ≤20m, adjustable according to the actual scenario), uses a short-distance connection: the adsorption head is directly connected to the inlet of the pulverizing device via a quick-connect structure, the outlet of the pulverizing device is connected to the adsorption pipe via the quick-connect structure, and the other end of the adsorption pipe is connected to the communication interface of the sealed collection chamber, forming a short-distance adsorption path of "adsorption head - pulverizing device - adsorption pipe - sealed collection chamber". After connection, check the sealing of each connection to ensure no air leakage and avoid affecting the negative pressure adsorption effect.

[0046] The second method, used when the adsorption point is far from the sealed collection chamber (usually >20m), employs a long-distance connection: the adsorption head is connected to one end of an extension pipe via a quick-connect structure, the other end of the extension pipe is connected to the inlet of the pulverizing device via a quick-connect structure, the outlet of the pulverizing device is connected to the adsorption pipe, and the adsorption pipe is connected to the sealed collection chamber, forming a long-distance adsorption path of "adsorption head - extension pipe - pulverizing device - adsorption pipe - sealed collection chamber". The length of the extension pipe is spliced ​​according to the actual adsorption distance to ensure that the adsorption head can cover the target collection area. Simultaneously, a fixing bracket is used to secure the extension pipe and the adsorption pipe, preventing pipe shaking or displacement.

[0047] After the path connection is completed, the main system power is turned on, the system control module is initialized, and each core device performs a self-test. Upon successful self-test, the negative pressure device inside the sealed collection chamber is activated. The negative pressure device begins operation, creating a stable negative pressure airflow within the sealed collection space, adsorption pipes, crushing device, and adsorption head. The negative pressure intensity is automatically adjusted according to the adsorption path length, maintaining a lower negative pressure for close-range adsorption and a higher negative pressure for long-range adsorption, ensuring sufficient power for the adsorption and transport of green waste. Simultaneously, the vision camera is activated, beginning real-time image data acquisition within the sealed collection chamber. The system then enters standby mode, awaiting green waste collection instructions.

[0048] Step 2: Green Waste Adsorption and Transfer After the system enters standby mode, the operator moves the adsorption head to the green waste collection area, aligning the flared inlet of the adsorption head with the target green waste (such as fallen leaves, grass clippings, branches, etc.). Under the action of negative pressure airflow, the green waste is sucked into the adsorption head. The isolation mesh at the inlet of the adsorption head filters the green waste, intercepting large branches that exceed the preset size, allowing only green waste that meets the requirements to enter the adsorption head through the isolation mesh, preventing large branches from entering subsequent pipes or crushing devices and causing blockages or damage.

[0049] If the adsorption point is far away or the resistance of the green waste is high (such as damp branches or clumps of grass clippings), the system control module automatically activates the independent negative pressure generating device inside the adsorption head according to the adsorption conditions. The independent negative pressure generating device works in conjunction with the negative pressure device in the chamber to form a stronger local negative pressure adsorption force at the inlet of the adsorption head, ensuring that the green waste can be smoothly sucked in and transported along the pipeline. During the adsorption process, the system monitors the negative pressure value and the green waste transport status in real time. If the negative pressure value is lower than the preset threshold, the operating power of the negative pressure device is automatically increased to enhance the negative pressure intensity. If poor green waste transport is detected (such as an abnormally high negative pressure value but no green waste transport signal), it is determined that there is a partial blockage in the adsorption head or pipeline, and an alarm message is immediately issued to remind the operator to stop the machine for cleaning.

[0050] The green waste entering the adsorption head is drawn along the adsorption path (short-distance path or long-distance path) to the crushing device under the traction of the negative pressure airflow. During the transportation process, the smooth structure of the inner wall of the pipe and the stable negative pressure airflow ensure that the green waste will not accumulate in the pipe, realizing the continuous and stable transmission of green waste.

[0051] Step 3: Green waste separation and crushing After being transported to the pulverizing device via the adsorption pipe (or extension pipe), the green waste enters the main channel inlet of the pulverizing device. Automatic diversion is achieved through the airflow guiding structure at the main channel inlet, allowing the waste to be processed differently based on its texture and particle size, either entering the pulverizing chamber or the bypass channel. For medium-to-heavy green waste such as branches, due to their large weight, they cannot overcome gravity to enter the bypass channel along the guide structure and naturally fall into the main channel, where they are transported to the crushing chamber by the airflow. Once the system control module detects the medium-to-heavy green waste entering the crushing chamber, it automatically activates the coarse crushing mechanism inside. The coarse crushing mechanism begins to rotate and cut, coarsely crushing the medium-to-heavy green waste to a particle size that meets the requirements for pipeline transport. During the crushing process, a screen inside the crushing chamber filters the crushed green waste. Green waste that meets the particle size requirements falls downstream of the main channel through the screen, while green waste that does not meet the requirements continues to be crushed in the crushing chamber until it meets the particle size requirements and then passes through the screen. The coarse crushing mechanism only performs non-fine crushing to ensure processing efficiency and reduce energy consumption and equipment wear.

[0052] Lightweight green waste such as grass clippings and leaves, due to their light weight, are guided by the negative pressure airflow into the bypass channel along the guide structure at the main channel entrance. They bypass the pulverizing chamber directly and are transported downstream of the main channel without further pulverization, merging with the pulverized medium-to-heavyweight green waste. This diversion method effectively improves the overall processing efficiency of green waste, avoids light green waste from occupying the workload of the pulverizing device, reduces energy consumption and wear on the pulverizing device, and extends the equipment's service life.

[0053] After being diverted and pulverized, the green waste (light green waste and crushed medium-to-heavy green waste) enters the adsorption pipe downstream of the main channel under the action of negative pressure airflow, and continues to be transported to the sealed collection chamber. During the operation of the pulverizing device, the system monitors its operating status in real time. If any abnormalities such as overload of the pulverizing mechanism or equipment failure are detected, the pulverizing device will be stopped immediately and an alarm message will be issued to remind the operator to carry out maintenance.

[0054] Step 4: Monitoring of Green Waste Storage and Accumulation The green waste, transported via adsorption pipes, enters the sealed collection space inside the sealed collection chamber through a connection interface, completing the centralized storage of the green waste. After entering the sealed collection space, the green waste naturally accumulates under the influence of gravity. A visual camera captures images of the green waste accumulation in real time and transmits the image data to the system control module. The control module uses image recognition algorithms to analyze the green waste accumulation height, accumulation range, and accumulation volume, achieving real-time monitoring of the green waste accumulation status.

[0055] The system has a preset threshold for the amount of green waste that can accumulate (usually set at 70% of the storage capacity, but adjustable based on actual collection frequency). When the control module determines that the accumulated green waste has reached the preset threshold, it immediately sends a collection alert to the management terminal, reminding managers to arrange for collection vehicles. Simultaneously, the system can also issue a warning signal locally via indicator lights or a buzzer, ensuring timely notification to on-site personnel. If the accumulated green waste continues to rise, reaching a preset emergency threshold (usually 90% of the storage capacity), the system automatically reduces the operating power of the negative pressure device to decrease the amount of green waste entering, preventing excessive accumulation that could lead to blockages or equipment malfunctions, until the collection process is complete.

[0056] During the green waste storage process, visual cameras also monitor the distribution of green waste accumulation in real time. If uneven accumulation of green waste is detected inside the storage chamber (such as excessively high accumulation height in a certain area, or excessive distance from the chamber exit), the system control module automatically sends a control command to activate the tracked pushing device at the bottom. The tracked pushing device moves along a preset trajectory, pushing the green waste in a predetermined direction (towards the chamber exit), ensuring that the green waste is evenly accumulated within the sealed collection space, preventing localized clumping, and simultaneously pushing the green waste to a position closer to the exit, preparing for subsequent removal work.

[0057] During operation, the tracked conveyor system monitors its running status and position in real time, adjusting the conveying speed and distance according to the accumulation of green waste to ensure effective conveying. If green waste is detected to be stuck during the conveying process (e.g., due to excessive load on the conveyor), the conveying operation is immediately paused, and attempts are made to clear the blockage by reversing the movement. If the blockage cannot be cleared, an alarm is issued to remind the operator to clean up the site.

[0058] Step 5: Green Waste Removal and Equipment Maintenance After receiving the waste collection notification, management personnel arrange for a waste collection vehicle to arrive at the sealed collection room. They then open the sealed door 7 at the room's exit and activate the tracked pushing device to move the waste towards the exit, facilitating its smooth discharge to the waste collection vehicle. The retractable structure of the room's exit guides the waste to be discharged in a concentrated manner, preventing scattering and improving collection efficiency.

[0059] After the green waste collection is completed, the management personnel send a completion command through the management terminal. The system control module controls the tracked pusher to return to its initial position, closes the sealed door at the chamber's exit, restores the negative pressure device to normal operating power, and the system re-enters standby mode, awaiting the next round of green waste collection. Simultaneously, the visual camera captures images of the chamber's interior to confirm that the accumulated green waste has decreased to a preset lower limit (usually below 10% of the chamber's storage capacity), completing the closed loop of the collection process.

[0060] During system operation, the power status of the crushing device and adsorption head is monitored in real time (for battery-powered mode). When the device power is detected to be lower than a preset threshold, a charging reminder is issued. If the crushing device has an automatic return function, it can return to the charging area of ​​the sealed collection chamber along a preset trajectory under the guidance of the control module, and connect to the charging interface for charging to ensure the equipment's continued operation capability.

[0061] During routine maintenance, operators can periodically disassemble the isolation screen of the adsorption head to remove intercepted large branches and debris; check the sealing of each device connection and replace damaged seals promptly; inspect the crushing mechanism and screen of the crushing device and clean any residual green waste debris; and clean the vision camera lens to ensure clear image acquisition. Regular maintenance ensures long-term stable system operation and extends equipment lifespan.

[0062] This invention describes a distributed automated collection system and method for garden waste. Through the rational design of the sealed collection chamber, adsorption pipes, crushing device, and adsorption head, an integrated automated waste collection system is constructed. It strictly implements all technical features defined in the claims, achieving efficient, intelligent, and environmentally friendly collection and treatment of distributed garden waste. The system features adaptive path configuration to flexibly adapt to adsorption needs at different distances; a diversion and crushing mechanism to achieve differentiated treatment of different types of waste, improving efficiency and equipment stability; and visual monitoring and intelligent linkage to achieve real-time control of waste accumulation and automatic removal reminders, reducing manual intervention.

[0063] The implementation of this invention effectively solves the problems of existing garden waste collection, such as reliance on manual labor, low efficiency, poor adaptability, and easy pollution. It can be widely applied to various distributed garden scenarios such as community green spaces and urban parks, and has good practicality and promotional value. In practical applications, the building size, pipe length, threshold parameters, etc., can be appropriately adjusted according to the amount of green waste generated and terrain conditions of the specific scenario. As long as they conform to the core technical concept of this invention and the technical features defined in the claims, they all fall within the protection scope of this invention.
