[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0023] As attached Figure 1 To be continued Figure 3 As shown:
[0024] This utility model provides an automatic sorting device for household waste, which includes a frame 1 as the main body and integrates a temporary storage component 2, a material guiding component 3, a rotating dispensing component 5 and an intelligent identification system to realize the full automation of the waste from identification, temporary storage to sorting and disposal.
[0025] As attached Figure 1 To be continued Figure 2 As shown: The frame 1 adopts a metal frame structure, with protective plates on the top and sides. The top protective plate has a disposal port 7 in the center, and the bottom is divided into four waste sorting areas for placing collection bins 6.
[0026] As attached Figure 1 To be continued Figure 2 As shown: The temporary storage component 2 includes two paired hoppers 201 and a rotary power component 202 (such as a servo motor). The hoppers 201 are hinged and mounted directly below the inlet 7. The rotary power component 202 is fixed to the side wall of the frame 1 and connected to the hoppers 201 via a connecting rod, driving the hoppers to open and close. Waste falls into the hoppers 201 through the inlet 7 for temporary storage. The rotary power component 202 controls the hoppers to tilt and unload, preventing waste accumulation.
[0027] As attached Figure 1 To be continued Figure 2As shown: The material guiding assembly 3 includes a horizontal plate 301, a conveyor belt 302, a baffle 303, and a distribution plate. The horizontal plate 301 is symmetrically installed in the middle of the frame 1 to support the conveyor belt 302 and the horizontal conveyor belt 4. The conveyor belt 302 is inclined (angle 30°-45°) and has anti-slip texture on its surface. The upper end receives the unloading material from the hopper 201 through the distribution plate 304, and the lower end is connected to the baffle 303. The conveyor belts 302 on both sides convey in opposite directions, realizing the horizontal outward conveying of waste along the baffle 303. The baffle 303 includes a baffle plate 3031 and a guide plate 3032. The baffle plate 3031 is perpendicular to the lower end of the conveyor belt, and the guide plate 3032 is inclined and guided to the horizontal conveyor belt 4. The distribution plate 304 is fixed below the two hoppers 201 and seamlessly connected to the upper end of the conveyor belt 302. The horizontal conveyor belt 4 is installed at the lower end of the horizontal plate 301 and aligned with the guide plate 3032. The inclined conveyor belt 302 quickly transports waste, the material distribution plate 304 evenly distributes the material, and the baffle 303 controls the flow rate of waste and guides it to the horizontal conveyor belt 4 to avoid slippage errors.
[0028] As attached Figure 1 To be continued Figure 3 As shown: The rotating dispensing assembly 5 consists of a rotating drive 501, an inclined turntable 502, a sector-shaped disk 503, a material-pushing plate 504, and a servo motor 505. The rotating drive 501 uses a servo motor, fixed to the bottom of the frame 1, and drives the inclined turntable 502 to rotate. The inclined turntable 502 is mounted on the output shaft of the rotating drive 501, with its surface tilted at 15°. The sector-shaped disk 503 is fixedly mounted on its upper surface, with a sector angle of 90°-180°. The servo motor 505 is fixed to the upper surface of the sector-shaped disk 503, and the material-pushing plate 504 is mounted on the output shaft of the servo motor 505. The sector-shaped disk 503 is located directly below the end of the horizontal conveyor belt 4. The rotating drive 501 drives the inclined turntable 502 to rotate the sector-shaped disk 503 above the designated sorting area. The servo motor 505 drives the material-pushing plate 504 to push the waste into the collection bin 6, with a positioning error of <2cm.
[0029] As attached Figure 1 As shown: Two cameras 8 are respectively installed at both ends of the sorting plate 304. The cameras 8 are aimed at the horizontal conveyor belt 4, and their field of view covers at least a portion of the horizontal conveyor belt, enabling them to photograph the waste on the horizontal conveyor belt 4. The device uses a Jetson Nano development board equipped with an intelligent recognition system based on the Yolov8 algorithm. It captures images of the waste in real time, identifies the type using the Yolov8 algorithm, and transmits the data to the control system to plan the sorting path.
[0030] Working principle: The user pours the mixed waste into the inlet 7, and the hopper 201 closes to temporarily store it.
[0031] The rotating power component 202 drives the hopper 201 to tilt and unload onto the conveyor belt 302. The dividing plate 304 evenly distributes the waste onto both sides of the conveyor belt 302. The waste slides down the inclined conveyor belt 302 to the baffle plate 3031, and then is horizontally conveyed by the conveyor belt 302 to the guide plate 3032. The guide plate 3032 guides the waste to the horizontal conveyor belt 4. The camera 8 captures images of the waste. The Jetson Nano runs the Yolov8 algorithm to identify the type (such as recyclable waste, hazardous waste, kitchen waste, and other waste). The control system generates sorting instructions, and the waste is uniformly conveyed by the horizontal conveyor belt 4 to the fan-shaped disk 503.
[0032] The rotary drive 501 drives the inclined turntable 502 to rotate, so that the fan-shaped disk 503 is aligned with the target sorting area. The servo motor 505 drives the material feeding plate 504 to rotate, pushing the garbage into the corresponding collection bin 6 to complete the sorting.
