Description

Technical Field

[0001] This invention relates to the field of leaf composting technology, specifically an intelligent leaf recycling and composting device. Background Technology

[0002] Currently, cities across my country are increasing their investment in landscaping and greening to improve the urban living environment. Every autumn, especially in northern cities, the leaves on the streets, in residential areas, and in parks turn from green to yellow, falling with the wind, creating a thick carpet of yellow and red leaves that forms a beautiful landscape. While fallen leaves add vibrant color to autumn, they also place enormous pressure on urban environmental management. With increasing urbanization and the rapid growth of urban greenery, the seasonal problem of fallen leaves is becoming a significant challenge for many cities.

[0003] Currently, the main methods for handling seasonal fallen leaves in Chinese cities are centralized landfill, incineration, biofuel, and composting. However, the existing centralized composting model requires large initial investments, has a long cycle, and high labor costs, with fixed investments often reaching tens of millions of yuan. The high operating costs in the later stages place a heavy burden on local finances, making "environmental protection" difficult. Furthermore, the commonly used methods are primarily incineration and landfill, mainly involving sanitation workers sweeping up the leaves and transporting them to waste treatment sites via garbage trucks, where they are then disposed of through landfill, incineration, or kitchen waste treatment. Autumn in northern cities results in particularly large amounts of fallen leaves. This not only consumes significant human and material resources but is also environmentally unfriendly, affecting not only the city's aesthetics but also potentially causing air, water, and soil pollution, thus impacting the health of urban residents and hindering the construction of ecological cities.

[0004] Patent document CN215403923U discloses a composting device for garden dead branches and fallen leaves, including a compost bin. An air intake fan is installed on one side of the compost bin, and an air intake pipe is connected to the air intake of the fan. An exhaust port is located at the top of the compost bin, and one end of the air intake pipe is connected to the exhaust port, which is located on the side wall of the compost bin. The air outlet of the air intake fan is connected to a salt solution tank for absorbing ammonia gas, and the salt solution tank is connected to an alkaline solution tank for absorbing hydrogen sulfide gas. This invention, by incorporating the salt solution tank and the alkaline solution tank, can absorb ammonia and hydrogen sulfide gas from odorous gases. Furthermore, the activated carbon inside the adsorption tank can adsorb other toxic and harmful gases in the odorous gases. An opening and closing plate within the connecting assembly restricts the gas flow direction within the air intake pipe, reducing the entry of external gases into the compost bin.

[0005] However, existing technologies still have shortcomings: Existing devices are simply fermentation tanks. When in use, the collected whole fallen leaves need to be put into the fermentation tank. However, sanitation workers need to sweep up piles of dead branches and fallen leaves beforehand, and then load them into garbage trucks and transport them to the garbage treatment plant for processing. This is time-consuming, labor-intensive, and costly. It is not convenient to process fallen leaves quickly anytime and anywhere, which reduces the practicality of the device.

[0006] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to overcome the above-mentioned defects and provide an intelligent leaf recycling and composting device.

[0008] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: an intelligent leaf recycling and composting device, comprising a fermentation chamber, characterized in that: A collection chamber is located at one end of the fermentation chamber; A filter chamber is located at one end of the collection chamber; A solar panel is located on top of the fermentation chamber.

[0009] Furthermore, both ends of the fermentation chamber are fixedly connected to branch pipes, one end of which is fixedly connected to the inside of the collection chamber. A stirring device is installed at the bottom of the fermentation chamber, a driving device is provided at one end of the bottom of the fermentation chamber, a temperature and humidity sensor is installed at one end of the middle of the fermentation chamber, and a gas sensor is installed at the other end of the middle of the fermentation chamber.

[0010] Furthermore, the collection chamber is provided with a door at the top, a second drive device is provided at the upper front end of the collection chamber, a touch sensor is fixedly installed on the front end of the top surface of the door, and a press sensor is fixedly installed on the front end of the bottom surface of the door.

[0011] Furthermore, one end of the filter chamber extends into the collection chamber, a mesh plate is provided at the end of the filter chamber near the collection chamber, a fan is fixedly installed inside the filter chamber, a return pipe is fixedly installed at the end of the filter chamber away from the collection chamber, and a grid plate is provided on the top of the return pipe.

[0012] Furthermore, the fermentation chamber is hinged to a top plate, and the solar panel is fixedly installed on the top of the top plate.

[0013] This invention also provides an intelligent method for recycling and composting fallen leaves, comprising the following steps: S1. The drive unit 2 is activated by contacting the touch sensor, opening the compartment door; S2. Sweep the fallen leaves into the collection chamber and close the chamber door by pressing the sensor; S3. Start the fan. The fan blows the fallen leaves into the fermentation chamber through the branch pipe, leaving behind larger debris such as small stones. The fallen leaves and small stones are automatically separated. S4. Start the drive device to drive the stirring device to rotate and start stirring the fallen leaves; S5. Remotely monitor and control the temperature and humidity during the fermentation process using temperature and humidity sensors; S6. Remotely monitor and control gas and other parameters during the fermentation process using gas sensors to determine whether fermentation is complete; S7. Open the fermentation chamber and take out the fermented organic fertilizer.

[0014] The advantages of this invention compared to the prior art are: (1) When using this invention, the device can be placed on the ground of roads, parks and communities where there are many fallen leaves. When there are fallen leaves, the device can be turned on, the fallen leaves can be placed in the device, and then the temperature and humidity can be controlled, microbial fertilizer can be added, and the fallen leaves can be rapidly degraded and composted through aerobic fermentation technology. The fallen leaves can be fermented into usable organic fertilizer for flowers, grass and trees, which is convenient to quickly process fallen leaves anytime and anywhere. It not only solves the problem of many fallen leaves in the city and the cumbersome processing, but also produces organic fertilizer for the recycling of fallen leaves. It also reduces the environmental pollution caused by the garbage disposal method. It can be recycled, which can reduce the labor intensity of sanitation workers and reduce the processing cost. (2) In this invention, the entire process of leaf processing is integrated by setting up a fermentation chamber, a collection chamber, a filtration chamber and a solar panel. This allows the device to open and close the door after being touched, automatically separate fallen leaves and pebbles, stir fallen leaves, and remotely monitor and control parameters such as temperature, humidity and gas during the fermentation process. This achieves automated operation, so that the fallen leaves collected in the city are not treated as garbage, but are fermented aerobically with microbial fertilizer, turning waste into treasure and forming organic fertilizer. This realizes resource utilization, conforms to the concept of circular economy and sustainable development, and improves the practicality of the device. Attached Figure Description

[0021] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 5 As shown in the figure, this embodiment proposes an intelligent leaf recycling composting device, including a fermentation chamber 1, a collection chamber 2 at one end of the fermentation chamber 1, and a filter chamber 3 at the other end of the collection chamber 2.

[0024] It should be noted that, through preliminary fermentation experiments, the fermentation effect of "Fenbao Compound Microbial EM Bacteria" is better than that of "Bio-fertilizer Composting Fermentation Agent." "Fenbao" ferments more completely during the fermentation process and is less prone to producing insects and fungi. Therefore, the use of "Fenbao Compound Microbial EM Bacteria," after preliminary fermentation experiments, proves that this fermentation method is feasible. By selecting optimal strains, complete fermentation of fallen leaves can be achieved within 20-30 days.

[0025] When in operation, the device is placed on the ground in areas with abundant fallen leaves, such as roads, parks, and residential areas. When fallen leaves are present, the device is activated, and the leaves are placed inside. Under controlled temperature and humidity, microbial fertilizer is added, and aerobic fermentation technology rapidly degrades and composts the fallen leaves, turning them into usable organic fertilizer for plants and trees. This allows for quick and convenient processing of fallen leaves anytime, anywhere. Instead of relying on traditional waste disposal methods, urban fallen leaves are aerobically fermented using microbial fertilizer, transforming waste into valuable organic fertilizer. This also reduces air pollution caused by burning fallen leaves as garbage, lessens the workload of sanitation workers, lowers processing costs, and achieves resource utilization, aligning with the concepts of circular economy and sustainable development.

[0026] Both ends of the fermentation chamber 1 are fixedly connected to branch pipes 11. One end of the branch pipe 11 is fixedly connected to the inside of the collection chamber 2. A stirring device 12 is installed at the bottom of the fermentation chamber 1. A drive device 13 is provided at one end of the bottom of the fermentation chamber 1. The drive device 13 is a geared motor, which is controlled by an L298N motor drive board. The geared motor and the stirring device 12 can be driven by gear meshing. All of the above are existing technologies and will not be described in detail here.

[0027] A temperature and humidity sensor 14 is installed at one end of the middle of the fermentation chamber 1, and a gas sensor 15 is installed at the other end of the middle of the fermentation chamber 1. Both the temperature and humidity sensor 14 and the gas sensor 15 are existing products on the market, and their connection and control methods are existing technologies, which will not be described in detail here.

[0028] During operation, the composting status is monitored using a temperature and humidity sensor 14, and the temperature, humidity and gas emissions of the fermenting material are detected using the temperature and humidity sensor 14 and the gas sensor 15. Adjustments are made in a timely manner. An ESP8266 IoT module and a voltage regulator module are used. The IoT backend is SIOT, which uses an MQTT module. The backend is monitored and controlled via IoT. All of the above are existing technologies and will not be described in detail here.

[0029] The collection chamber 2 is equipped with a door 21 at the top and a drive device 22 at the upper front side of the collection chamber 2. The drive device 22 adopts an SG90 servo motor. All of the above are existing technologies and will not be described in detail here.

[0030] Furthermore, a gear transmission structure or linkage mechanism can be used to transmit the rotational motion of the servo motor to the rotating shaft, which in turn drives the door 21 to flip.

[0031] A touch sensor 23 is fixedly installed on the front end of the top surface of the compartment door 21, and a press sensor 24 is fixedly installed on the front end of the bottom surface of the compartment door 21. Both the touch sensor 23 and the press sensor 24 are existing products on the market, and their connection methods and control methods are existing technologies, which will not be described in detail here.

[0032] During operation, the device is controlled by a drive unit 22 (servo motor), a touch sensor 23, and a press sensor 24. When the touch sensor 23 detects an object approaching, it sends a high-level signal to the servo motor, which rotates. The rotational motion of the servo motor is transmitted to the rotating shaft through a linkage mechanism. The rotating shaft drives the door 21 to flip open, allowing the device to be touched and the door to be opened and closed.

[0033] One end of the filter chamber 3 extends into the collection chamber 2. A mesh plate 31 is provided at the end of the filter chamber 3 near the collection chamber 2. A fan 32 is fixedly installed inside the filter chamber 3. The fan 32 is a powerful fan. The above is the prior art and will not be described in detail here.

[0034] A return pipe 33 is fixedly installed at the end of the filter chamber 3 away from the collection chamber 2. A grid plate 34 is provided on the top of the return pipe 33. The return pipe 33 is L-shaped and passes through the perforated grid plate 34 to facilitate the return of air intake when the fan 32 is started.

[0035] During operation, the fan 32 is activated to filter the fallen leaves swept into the collection chamber 2, separating the leaves from the pebbles.

[0036] The fermentation chamber 1 is equipped with a solar panel 4 on its top. The top of the fermentation chamber 1 is hinged to a top plate, and the solar panel 4 is fixedly installed on the top of the top plate.
