[0039] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0040] While exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0041] like Figure 1 As shown, this utility model provides an intelligent sorting system for kitchen waste, used to remove inorganic components such as plastic bottles and aluminum cans from kitchen waste. These inorganic components are generally characterized by large volume and light weight, so this application adopts an air jet method for removal.

[0042] The intelligent sorting system for kitchen waste includes a controller and a vibrating feeder, a conveying device 2, an intelligent identification device 3, and a spray valve device, all electrically connected to the controller. The controller uses an existing circuit structure / integrated chip, and this application does not modify any of the controller's circuit structure / chip. The vibrating feeder is connected to the conveying device 2. Kitchen waste fed to the vibrating feeder is spread out on the vibrating feeder by vibration and its own weight, then slides onto the conveying device 2. This exposes inorganic components such as plastic bottles and aluminum cans from the kitchen waste, placing them primarily on the surface of the waste for easy identification by the intelligent identification device 3 and subsequent sorting operations.

[0043] The intelligent identification device 3 is slidably mounted on the conveying device 2 for easy adjustment of its position. The intelligent identification device 3 can identify the components and locations in the kitchen waste that need to be separated. When the conveying device 2 transports the kitchen waste under the intelligent identification device 3, the intelligent identification device 3 transmits the image data and coordinate data of the components to be removed to the controller. The controller then activates the spray valve device based on the image data and coordinate data. The spray valve device includes a spray plate mechanism 41, a material drop chute 42, and a sorting chute 43. The spray plate mechanism 41 is connected to the conveying device 2, allowing kitchen waste to enter it from the conveying device 2. The material drop chute 42 and the sorting chute 43 are located on one side of and below the spray plate mechanism 41, with the material drop chute 42 closer to the spray plate mechanism 41 and the sorting chute 43 further away. After the jet plate mechanism 41 is activated, high-pressure gas is sprayed at the location of the component that needs to be removed. The component that needs to be removed is blown up and falls into the sorting tank 43, which is farther away from the jet plate mechanism. The remaining waste components fall into the material drop trough 42 below along the jet plate mechanism 41 under their own gravity, thereby separating inorganic components such as plastic bottles and aluminum cans from kitchen waste.

[0044] This application can effectively separate inorganic components such as plastic bottles and aluminum cans from kitchen waste, which is conducive to the stable operation of subsequent processing technology, the resource utilization of kitchen waste, and avoids the drawbacks of manual sorting, effectively improving sorting efficiency.

[0045] Furthermore, the jet plate mechanism 41 has multiple through holes 44 arrayed on it, each through hole 44 containing at least one nozzle. Each nozzle is connected to a positive pressure air source via an air pipe equipped with a solenoid valve. The solenoid valve is electrically connected to the controller, enabling individual control of each nozzle. After the jet plate mechanism 41 is activated, the controller controls the opening time and degree of the solenoid valve of the corresponding nozzle based on the image data and coordinate data acquired by the intelligent recognition device 3 and the movement speed of the conveying device 2. This blows out inorganic components such as plastic bottles and aluminum cans of different sizes and positions on the surface of the kitchen waste moving onto the jet plate mechanism 41 from the kitchen waste.

[0046] Furthermore, the spray valve device also includes a mounting base and a telescopic rod 45, the lower end of which is hinged to the mounting base. The spray plate mechanism 41 is hinged to the conveying device 2, and the second end of the telescopic rod 45 is hinged to the bottom surface of the spray plate mechanism 41. The tilt angle of the spray plate mechanism 41 is adjusted by adjusting the length of the telescopic rod 45, thereby controlling the sliding speed of the kitchen waste on the spray plate mechanism 41. The spray distance and height can be adjusted by adjusting the angle of the spray plate mechanism 41.

[0047] See Figure 1The spray valve device also includes a first baffle plate 46 and a second baffle plate 47. The first baffle plate 46 is disposed between the discharge chute 42 and the sorting chute 43. The height of the first baffle plate 46 is lower than the height of the spray plate mechanism 41. It is used to prevent inorganic components such as plastic bottles and aluminum cans from falling back into the discharge chute 42 from the sorting chute 43, and also to prevent kitchen waste from splashing into the sorting chute 43. The second baffle plate 47 is vertically disposed on the side of the sorting chute 43 away from the spray plate mechanism 41. The height of the second baffle plate 47 is higher than the height of the spray plate mechanism 41. It is used to block the blown-out inorganic components such as plastic bottles and aluminum cans.

[0048] In a preferred embodiment, the cross-section of the first baffle plate 46 is triangular, which facilitates the rapid sliding of inorganic components such as plastic bottles and aluminum cans into the sorting tank 43, avoiding them from remaining on the top surface of the first baffle plate 11.

[0049] See Figure 1 The vibrating feeding device includes a vibrating panel and a vibrating motor. The vibrating panel is inclined and located above the conveying device 2, with its projected portion lying on the conveying device 2, ensuring that kitchen waste on the vibrating panel can slide onto the conveying device 2. The vibrating motor is located on the bottom surface of the vibrating panel and is used to drive the vibrating panel to vibrate. The controller is electrically connected to the vibrating motor and is used to control the start and stop of the vibrating motor. First baffles 11 are provided on both sides of the vibrating panel to prevent kitchen waste from falling off the sides of the vibrating panel during vibration. A first proximity sensor, preferably a photoelectric proximity sensor, is provided on the first baffle 11, and the first proximity sensor is electrically connected to the controller. When the first proximity sensor detects kitchen waste on the vibrating panel, the controller starts the vibrating motor.

[0050] The conveying device 2 includes a mounting frame, a conveyor motor, a conveyor belt, a drive roller, and multiple driven rollers. Both the drive roller and driven rollers are rotatably mounted on the mounting frame, and the conveyor motor is mounted on the mounting frame. The conveyor motor is connected to the drive roller to drive its rotation; the controller is electrically connected to the conveyor motor to control its start and stop. The conveyor belt is wound around the drive roller and driven rollers, with its upper surface horizontally positioned. The projected portion of the vibrating panel is located on the conveyor belt, ensuring that food waste on the vibrating panel can slide onto the conveyor belt. Second baffles 23 are provided on both sides of the conveyor belt to prevent food waste from falling. A second proximity sensor 21 is mounted on the second baffle 23. The second proximity sensor 21 is electrically connected to the controller. When the second proximity sensor 21 detects food waste, the conveyor motor is started, and the food waste passes under the intelligent identification device 3 along with the conveyor belt.

[0051] Preferably, the intelligent identification device 3 includes a movable support, a camera, and a supplementary light. The camera is preferably a digital camera with a charge-coupled device (CCD) image sensor, which can quickly acquire image and coordinate data of the kitchen waste and feed this data back to the controller. The movable support is slidably mounted above the conveyor device 2 via support legs 31 and rollers located on the ground. The camera and supplementary light are both located at the bottom of the movable support, facing the upper surface of the conveyor belt. Both the camera and supplementary light are electrically connected to the controller. As the kitchen waste passes under the camera along the conveyor belt, the camera receives the synthetic light signal from the selected kitchen waste under the influence of the supplementary light, transmitting the image and coordinate data of the kitchen waste to the controller.

[0052] like Figure 1 As shown, the intelligent kitchen waste sorting system also includes a garbage bin lifting device, which is connected to a vibrating feeding device. The garbage bin lifting device includes a lifting mechanism 52, a pressure sensor 53, and a third proximity sensor 51. The lifting mechanism 52 is connected to the conveying device 2 and can be detachably connected to the garbage bin and lifted to the height of the conveying device 2. The pressure sensor 53 is located on the lifting mechanism 52, and the third proximity sensor 51 is located on the top of the lifting mechanism 52. The lifting mechanism 52, pressure sensor 53, and third proximity sensor 51 are all electrically connected to the controller. After the kitchen waste bin is pushed onto the lifting mechanism 52, the pressure sensor 53 on the lifting mechanism 52 outputs a signal to the controller, which starts the lifting motor, and the garbage bin begins to lift. When the top of the garbage bin enters the tilting arc track at the top of the lifting mechanism 52, the third proximity sensor 51 outputs a signal to the controller, which stops the lifting mechanism 52. After the garbage bin completes the tilting action, the lifting mechanism 52 resets.
