Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] With the continuous increase in the amount of household waste, waste sorting and disposal is crucial for environmental governance. Traditional waste sorting mainly relies on manual sorting, which is not only costly in terms of labor and inefficient, but also prone to errors and omissions, resulting in low sorting accuracy.

[0020] Based on this, intelligent sorting trash cans have been developed to replace manual sorting as the mainstream equipment. However, current intelligent sorting trash cans can only perform semi-automatic sorting of loose waste. For example, they can only handle loose waste; for common bagged waste, manual assistance is still required. They cannot automatically break open bags or disperse waste, resulting in low processing efficiency and a high risk of secondary pollution. In addition, the waste inside the cans tends to become loose and unstable, leading to underutilization of internal space, high frequency of waste collection, and higher costs.

[0021] This application provides an automatic bag-breaking intelligent sorting and compression garbage bin. Addressing the shortcomings of existing garbage sorting equipment, such as its inability to handle whole bags of garbage, low sorting accuracy, and poor space utilization, this bin is based on an integrated design that integrates functions such as garbage bag breaking, vibration dispersion, visual recognition, sorting and grabbing, and compression and storage. Each mechanism works in sequence according to the garbage processing workflow, achieving fully automated operation of the entire process from garbage disposal, bag breaking, dispersion to accurate identification, sorting and grabbing, and compression and storage. This improves garbage sorting efficiency and accuracy, while also fully utilizing the internal storage space, solving the problems of overfilled or empty garbage bins, and increasing space utilization.

[0026] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0027] In this application, "multiple" means two or more (including two).

[0028] Please refer to Figure 1 and Figure 2 This application provides an automatic bag-breaking intelligent sorting and compressing garbage bin, including a bin body 1. The bin body 1 is a basic load-bearing component, and its main frame is constructed of aluminum alloy profiles. Aluminum alloy profiles offer both high structural strength and lightweight properties, facilitating transportation, installation, and routine maintenance. Alternatively, the bin body 1 can also be made of materials such as plastic or stainless steel. The bin body 1 contains a garbage channel 5 and a garbage disposal opening 7, which is connected to the garbage channel 5. During use, fully bagged garbage can be deposited into the bin body 1 through the garbage disposal opening 7.

[0029] Specifically, the garbage disposal port 7 is fixedly and inclinedly connected to the garbage channel 5. One end of the garbage channel 5 is connected to the garbage disposal port 7, and the other end extends downward at an incline to the upper side of the bag breaking and cutting module 2. The inner wall of the garbage channel 5 is smoothed to reduce the frictional resistance of the garbage bag during its fall and ensure that the garbage bag can slide down smoothly.

[0030] The waste disposal opening 7 is equipped with a disposal opening baffle 8, which is hinged to the waste disposal opening 7. The disposal opening baffle 8 is made of transparent flame-retardant material and hangs down naturally when no waste is being disposed of, sealing the interior space of the bin and preventing odors from escaping and insects from entering. A bin door 10 is installed on the front side of the bin body 1 via a hinge, facilitating the cleaning of waste inside the bin and equipment maintenance.

[0031] Furthermore, a sensing area 11 is provided on the top of the housing 1. The sensing area 11 has a built-in infrared sensor to detect human signals in real time. When the sensing area 11 detects a human signal, it drives the dispensing port baffle 8 to open automatically.

[0032] A bag-breaking and cutting module 2 is fixedly installed inside the container 1, located below the garbage inlet 7. When a bag of garbage enters through the inlet, it falls under gravity and reaches the working area of ​​the bag-breaking and cutting module 2. The bag-breaking and cutting module 2 can pull, break, and cut the entire garbage bag, releasing the mixed garbage inside, which falls into the processing area below, achieving complete unloading of the entire bag of garbage.

[0033] Furthermore, a vibrating separation module 3 is fixedly installed on the lower side of the bag breaking and cutting module 2. The vibrating separation module 3 includes a waste dispersion tray 31, a vibration drive device 32, and a waste storage bin 33. The waste dispersion tray 31 can be a rectangular temporary storage box with an open top, and its opening faces the outlet of the bag breaking and cutting module 2. It can receive the mixed waste released from the bag breaking and cutting module 2 to achieve vibration dispersion and sorting pretreatment.

[0034] When mixed waste falls into the waste dispersion tray 31, it is piled up in an overlapping state. If it is directly identified and sorted, it is very easy to cause identification errors or failure to grab due to the overlapping of waste.

[0035] To improve grasping accuracy, the oscillation drive device 32 is connected to the waste dispersion disk 31, enabling the disk to perform reciprocating oscillation motion. During oscillation, the mixed waste piled together in the waste dispersion disk 31 is gradually and evenly dispersed by the vibration, spreading evenly on the disk, thus effectively avoiding the impact of waste overlap on subsequent identification accuracy. The remaining waste storage bin 33 can store unidentified waste (e.g., wet waste and other harmless and useless waste).

[0036] In one specific embodiment, a visual recognition and grasping module 4 is provided on the upper side of the waste dispersion tray 31. This module includes a visual recognition unit 41, a grasping unit 42, and a waste conveyor belt 43. The visual recognition unit 41 can employ a high-definition camera, with its shooting direction facing the interior of the waste dispersion tray 31. It has a built-in lighting system and collects image information of the waste in real time, transmitting it to an external control system to achieve intelligent identification of waste types, providing visual guidance for the precise grasping action of the grasping unit 42. The visual recognition unit 41 can identify multiple preset waste categories (e.g., hazardous waste, plastic waste, metal waste, and paper waste). The identification results can serve as the basis for the subsequent actions of the vibration separation module 3.

[0037] A gripping unit 42 is provided on the upper side of the waste dispersion tray 31, and the gripping unit 42 is electrically connected to the vision recognition unit 41. The gripping unit 42 can grip the waste of a preset category according to the waste type information output by the vision recognition unit 41 and place it on the waste conveyor belt 43. The waste is then transported by the waste conveyor belt 43 to the sorting, compression and storage module 6 to achieve waste sorting, such as separating dry waste from wet waste, hazardous waste from recyclable waste, and plastic waste from metal waste.

[0038] It should be noted that the preset categories of garbage identified and captured in the embodiments of this application can be arbitrarily changed according to the needs of the usage scenario, and this application does not limit them.

[0039] In this embodiment, a step-by-step processing method can be adopted. For example, firstly, the grasping unit 42 in the visual recognition grasping module 4 grasps out four types of dry waste—hazardous waste, plastic waste, metal waste, and paper waste—one by one according to the recognition result and transfers them to the classified waste bin 61. After all four types of dry waste have been grasped, the vibration separation module 3 activates, opening the bottom of the waste dispersion tray 31, allowing all the remaining waste that was not grasped to fall into the remaining waste storage bin 33 below. The remaining waste includes all the ungrabbed waste, including wet waste and other harmless and useless waste. Through the step-by-step processing method of grasping first and then releasing, the separation of dry waste and wet waste is achieved, ensuring that dry waste is classified and recycled while avoiding the contamination of recyclable dry waste by wet waste.

[0040] A waste conveyor belt 43 is provided on the upper side of the waste dispersing tray 31. The waste conveyor belt 43 is fixedly connected to the crossbeam of the container 1 via a bracket. The surface of the waste conveyor belt 43 can be provided with an anti-slip structure, which can receive the four types of waste grabbed by the vision recognition grabbing module 4 and transport them to the sorting waste bins 61 respectively. Baffle plates 9 are fixedly installed on both sides of the waste conveyor belt 43 to prevent waste from falling during transportation.

[0041] like Figure 8 and Figure 9 As shown. In one specific embodiment, the sorting, compression, and storage module 6 includes sorting bins 61, a rotating mechanism 62, and a compression mechanism 63. Exemplarily, the number of bins 61 can be set to four, each storing different types of waste, such as hazardous waste, plastic waste, metal waste, and paper waste. It should be noted that the specific number, structure, distribution, and types of waste stored in the sorting bins 61 can be set according to actual needs, and this application does not impose any limitations.

[0042] The rotating mechanism 62 drives the sorting bin 61 to rotate. When the sorting bin 61 needs to receive waste, the rotating mechanism 62 rotates the bin to the side below the discharge position at the end of the waste conveyor belt 43. When the waste in the sorting bin 61 accumulates to a certain amount, the rotating mechanism 62 rotates the bin to the side directly below the compression mechanism 63. The compression mechanism 63 can vertically compress the waste in the sorting bin 61 that has reached its capacity threshold.

[0043] To effectively prevent garbage from falling outside the recycling bins 61 during disposal, a leak-proof flare 611 can be installed on the top of each recycling bin 61. The diameter of the leak-proof flare 611 is larger than the diameter of the recycling bin 61, and the two can be integrally molded to ensure strength. All three sides of the recycling bin 61 can adopt a large rounded corner structure to prevent garbage from getting stuck or remaining inside the bin, and to facilitate cleaning.

[0044] The compression mechanism 63 is located on the upper side of the classified garbage bin 61 and is fixed to the crossbeam of the box body 1. It can compress the garbage in the classified garbage bin 61 when it reaches the capacity threshold.

[0045] This application adopts a waste sorting and processing method of sorting first and then separating. That is, the visual recognition grasping module 4 and the vibration separation module 3 first grasp the waste of the preset category and transport it to the sorting waste bin 61. Then, the remaining waste that is not grasped is released into the remaining waste storage box 33 to achieve accurate separation.

[0046] In the initial state, all mechanisms, including the bag breaking and cutting module 2, the vibration separation module 3, the visual recognition and grasping module 4, and the sorting, compression, and storage module 6, are reset to their initial positions, waiting for waste to be disposed of.

[0047] When a user intends to deposit a full bag of garbage into the garbage disposal opening 7, the sensing area 11 detects a human signal and drives the opening baffle 8 to open automatically. The garbage falls at an angle along the garbage channel 5. When it reaches the bag-breaking device 21, the infrared sensor 217 detects the garbage bag and triggers the bag-breaking action. The bag-breaking and cutting module 2 pulls and cuts the top of the garbage bag, completing the complete unloading of the entire bag of garbage. The garbage falls into the garbage dispersion tray 31 below. The vibration drive device 32 is activated, driving the garbage dispersion tray 31 to vibrate horizontally, so that the garbage in the garbage dispersion tray 31 is evenly dispersed, avoiding the accumulation of garbage. After the oscillation and dispersion are completed, the visual recognition and grasping module 4 collects images of the garbage in the garbage dispersion tray 31 and transmits them to the control system for category identification. Based on the identification results, the control system prioritizes the activation of the rotating mechanism 62, rotating the corresponding category of sorting garbage bin 61 to the underside of the garbage conveyor belt 43. Subsequently, the grasping unit 42 accurately grasps the preset category of garbage and places it on the garbage conveyor belt 43. The garbage conveyor belt 43, through the cooperation of the anti-slip surface and the baffles 9 on both sides, stably transports the garbage to the corresponding sorting garbage bin 61 that has been positioned. After the collection of a single type of garbage is completed, the control system continues to identify the next type of garbage, repeating the rotation, positioning, accurate grasping, conveying, and storage process, and sequentially completing the classification and collection of different preset categories of garbage. After all the preset categories of garbage have been grasped, the opening and closing plate 314 at the bottom of the garbage dispersion tray 31 automatically opens, and the remaining garbage that has not been identified and grasped falls into the remaining garbage storage box 33 on the lower side, completing the garbage separation. After the separation is completed, the opening and closing plate 314 automatically closes, waiting for the next garbage disposal. This setup, based on the different application scenarios and waste treatment needs, can ensure the separate collection of hazardous and recyclable waste, as well as the effective separation of dry and wet waste, thereby ensuring the rational storage and utilization of waste.

[0048] In this solution, the functional modules work in tandem in the order of bag breaking, vibration dispersion, visual recognition, sorting and grasping conveying, and rotary compression and storage, forming a complete automated waste sorting and processing line. Users only need to put the whole bag of waste into the disposal port; without any manual assistance, the equipment can automatically complete the automated operations of bag breaking, dispersion, recognition, grasping, separation, compression, and storage. This solves the problems of existing waste sorting equipment, such as limited functionality, inability to handle whole bags of waste, low sorting accuracy, and poor space utilization.

[0049] like Figure 6As shown. Exemplarily, the gripping unit 42 includes a three-way displacement device 421 for the mechanical claw and a mechanical claw 422. The three-way displacement device 421 is disposed on the upper side of the waste dispersion tray 31, and its end is connected to the mechanical claw 422. The three-way displacement device 421 can precisely move the position of the mechanical claw 422 in three-dimensional space, enabling the mechanical claw 422 to accurately reach the upper side of each target waste and achieve precise positioning and gripping of the waste. After reaching the target position, the mechanical claw 422 performs a closing action to firmly grip the waste. Then, the three-way displacement device 421 moves the mechanical claw 422 to the upper side of the waste conveyor belt 43, and the mechanical claw 422 opens to release the waste. By repeating this process, the gripping unit 42 can grab all the pre-defined types of waste in the waste dispersion tray 31 and transfer them to the subsequent conveying and storage stages. The visual recognition-based orderly gripping method ensures that waste is accurately classified and collected, avoiding mixing between different types of waste.

[0050] In one specific embodiment, the three-dimensional displacement device 421 of the mechanical gripper includes a Y-axis displacement component, a Z-axis displacement component and an X-axis displacement component. The three displacement components work together to drive the mechanical gripper 422 to perform precise positioning at any position in three-dimensional space.

[0051] The Y-axis displacement assembly can drive the mechanical gripper 422 to move in the Y-axis direction. Exemplarily, the Y-axis displacement assembly includes a Y-axis slide rail 4211, a Y-axis slider 4212, a Y-axis stepper motor 4213, and a Y-axis lead screw 4214. The Y-axis slide rail 4211 is provided on the inner walls of the front and rear sides of the housing 1. The Y-axis slider 4212 is nested inside the Y-axis slide rail 4211 and can reciprocate along the Y-axis slide rail 4211, driving the mechanical gripper 422 to move in the Y-axis direction. The Y-axis stepper motor 4213 is connected to the Y-axis lead screw 4214, and the Y-axis lead screw 4214 and the Y-axis slider 4212 cooperate to form a lead screw and nut transmission pair, with the driving force provided by the Y-axis stepper motor 4213.

[0052] When the Y-axis stepper motor 4213 drives the Y-axis lead screw 4214 to rotate, the rotational motion of the Y-axis lead screw 4214 is converted into the linear motion of the Y-axis slider 4212. By controlling the rotation direction and rotation angle of the Y-axis stepper motor 4213, the displacement amount and displacement direction of the Y-axis slider 4212 in the Y-axis direction can be precisely controlled.

[0053] The Z-axis displacement assembly drives the mechanical gripper 422 to move in the Z-axis direction. The Z-axis displacement assembly includes a Z-axis slider 4215, a Z-axis slide rail 4216, a Z-axis stepper motor 4217, a Z-axis lead screw 4218, a second connecting rod 4219, and a partition 4220. The Z-axis slider 4212 is fixedly connected to the Z-axis slide rail 4216, and the Z-axis slider 4215 is nested inside the Z-axis slide rail 4216, allowing it to slide up and down along the Z-axis slide rail 4216. The Z-axis stepper motor 4217 is drive-connected to the Z-axis lead screw 4218, and the Z-axis lead screw 4218 and the Z-axis slider 4215 cooperate to form a lead screw and nut transmission pair. When the Z-axis stepper motor 4217 drives the Z-axis lead screw 4218 to rotate, the rotational motion of the Z-axis lead screw 4218 is converted into the linear motion of the Z-axis slider 4215. Two sets of Z-axis sliders 4215 are fixedly connected together by two second connecting rods 4219 to ensure that the left and right Z-axis sliders 4215 remain synchronized during movement and will not be skewed or stuck.

[0054] Reference Figure 6 The X-axis displacement assembly can drive the mechanical gripper 422 to move in the X-axis direction. The X-axis direction corresponds to the front-rear direction of the housing 1. Two sets of X-axis pulleys 4221 are sleeved on the second connecting rod 4219, and a partition 4220 is fixed between the two sets of X-axis pulleys 4221. One set of X-axis pulleys 4221 is connected to the X-axis worm gear 4222 by a key. The X-axis stepper motor 4224 is driven by the X-axis worm 4223, and the X-axis worm 4223 meshes with the X-axis worm gear 4222. When the X-axis stepper motor 4224 drives the X-axis worm 4223 to rotate, the X-axis worm 4223 drives the X-axis worm gear 4222 to rotate. The X-axis worm gear 4222, connected by a key, drives the X-axis pulley 4221 to roll on the second connecting rod 4219, thereby causing the partition 4220 to move along the X-axis direction. Based on the self-locking characteristic of the worm gear transmission method, the position of the mechanical claw 422 can be reliably locked after the motor stops rotating.

[0055] like Figure 7 As shown. Further, the mechanical gripper 422 is fixedly mounted on the partition 4220 and moves in three-dimensional space together with the partition 4220. The mechanical gripper 422 includes a stepper motor 4225, a first lead screw 4227, a first lead screw nut 4228, a connecting rod 4229, and multiple mechanical gripper heads 4230. The stepper motor 4225 is fixedly mounted on one side of the partition 4220, and its output shaft is connected to the vertically arranged lead screw. The first lead screw nut 4228 is fitted onto the first lead screw 4227 and can move up and down vertically as the first lead screw 4227 rotates. The first lead screw nut 4228 is hinged to one end of the connecting rod 4229, and the other end of the connecting rod 4229 is hinged to the mechanical gripper head 4230.

[0056] When the stepper motor 4225 drives the first lead screw 4227 to rotate, the first lead screw nut 4228 moves up and down along the axial direction of the first lead screw 4227. Through the transmission action of the connecting rod 4229, the three mechanical grippers 4230 are controlled to open and close synchronously along a preset trajectory. When the first lead screw nut 4228 moves upward, the connecting rod 4229 pulls the mechanical grippers 4230 inward to achieve the gripping action; when the first lead screw nut 4228 moves downward, the connecting rod 4229 pushes the mechanical grippers 4230 outward to achieve the releasing action.

[0057] In this embodiment, through the coordinated operation of the three-way displacement device 421 and the mechanical claw 422, the gripping unit 42 can accurately reach the location of any garbage in the garbage dispersion tray 31, and perform precise gripping and release operations, thus realizing the automated garbage sorting and gripping function based on visual recognition results.

[0058] Furthermore, the outer side of the first lead screw 4227 is covered by a housing 4226, which provides protection and isolation for the first lead screw 4227, preventing dust or debris from entering and affecting the transmission accuracy. The side wall of the housing 4226 has a long groove structure, which facilitates observation of the movement state of the first lead screw 4227 and effectively reduces the overall structural weight.

[0059] Furthermore, the mechanical gripper 4230 adopts a modular structural design. Its outer and top areas are rigid parts 4231, made of rigid metal, which have high structural strength and can grasp relatively soft, lightweight, and easily damaged waste. The sidewalls of the mechanical gripper 4230 are provided with flexible parts 4232, which can be embedded inside the rigid parts 4231. The flexible parts 4232 are made of flexible wear-resistant material and are used to grasp harder and irregularly shaped waste. At the same time, the flexible contact improves the stability and safety of the grasping.

[0060] Furthermore, the mechanical claw 4230 is equipped with anti-slip textures 4233, which increases the friction of the gripping contact surface, improves the success rate of gripping garbage, and prevents garbage from slipping during the gripping process.

[0061] In one specific embodiment, the opening and closing plate 314 is a movable plate at the bottom of the waste dispersion tray 31, hinged to the side wall of the waste dispersion tray 31 via a hinge, and its opening and closing action is controlled by a drive component. In the initial stage of waste processing, the opening and closing plate 314 is in a closed state, forming a complete receiving container together with the side wall of the waste dispersion tray 31 to receive all waste falling after the bags are broken. Throughout the entire waste grabbing operation performed by the grabbing unit 42, the opening and closing plate 314 remains closed to ensure that unprocessed waste does not fall prematurely. After the grabbing unit 42 has completed grabbing all the waste of the preset categories in a preset order, the remaining waste in the waste dispersion tray 31 includes wet waste and other harmless and useless waste. At this time, the control system sends an opening command to the drive component of the opening and closing plate 314, and the opening and closing plate 314 automatically flips downwards and opens, allowing the remaining waste in the waste dispersion tray 31 to fall downwards under gravity.

[0062] In one specific embodiment, the remaining waste storage bin 33 is located directly below the opening plate 314, and its opening size is larger than the bottom opening of the waste dispersion plate 31 to ensure that falling waste can accurately fall into the remaining waste storage bin 33. The remaining waste storage bin 33 is integrally molded from corrosion-resistant metal material, has good corrosion resistance, and can withstand the erosion of liquid sewage seeping from wet waste for a long time without damage. The remaining waste storage bin 33 can be slidably connected to the inner wall of the bin body 1, and can be easily pulled out and pushed in through the bin door 10 on the front side of the bin body 1. When the waste in the remaining waste storage bin 33 accumulates to a certain amount, maintenance personnel can open the bin door 10, pull out the remaining waste storage bin 33 as a whole, clean out the waste and sewage inside, and then push the bin back into place after cleaning.

[0063] Multiple drainage holes are evenly distributed on the surface of the hinged plate 314. The diameter of the drainage holes is set to allow sewage to pass through smoothly without allowing solid waste to leak out. During the sorting and grabbing process, sewage mixed in with wet waste can seep into the other waste storage bin 33 through the drainage holes in advance, reducing water accumulation in the waste dispersion tray 31. This helps the visual recognition and grabbing module 4 to capture clearer images of the waste, while also reducing the risk of sewage splashing when the hinged plate 314 is opened.

[0064] like Figure 3 and Figure 4 As shown. In one specific embodiment, the bag-breaking and cutting module 2 includes a bag-breaking device 21 and a bag-cutting device 22. The bag-breaking device 21 is fixedly installed on a suspension plate 216 on the upper side of the left inner wall of the housing 1. The suspension plate 216 extends horizontally outward from the inner wall of the housing 1 and is used to support the various functional components of the bag-breaking device 21. Reference Figure 3The bag-breaking device 21 specifically includes a hook 211, a slider 212, a slide rail 213, and a gear 215. The slide rail 213 is fixedly installed on the lower side of the garbage channel 5. The slide rail 213 has a long, narrow groove structure, providing precise linear motion guidance for the slider 212. The slider 212 is nested inside the slide rail 213 and can slide horizontally back and forth along the length of the slide rail 213. The right side of the slider 212 is fixedly connected to the hook 211. The fixed connection method can be welding, threaded fastening, or fastening with connectors. The hook 211 is made of corrosion-resistant metal, possessing high mechanical strength and good corrosion resistance, and can withstand the tensile force of the garbage bag for a long time without deformation or damage. Two sets of hooks 211 are provided, symmetrically arranged on the lower side of the garbage channel 5 outlet, with the hook tips of both sets of hooks 211 facing the outlet direction of the garbage channel 5. When the garbage bag falls from the garbage channel 5, the two sets of hooks 211 can hook the top of the garbage bag.

[0065] Furthermore, gear 215 is connected to slider 212 via bag-breaking connecting rod 214. Specifically, gear 215 is fixedly connected to one end of bag-breaking connecting rod 214, and the other end of bag-breaking connecting rod 214 is connected to slider 212. Gear 215, as a power input component, is connected to an external drive mechanism. When the drive mechanism rotates, it drives gear 215 to rotate, and the rotational motion of gear 215 is converted into linear reciprocating motion of slider 212 via bag-breaking connecting rod 214. When gear 215 rotates, bag-breaking connecting rod 214 pushes slider 212 to move horizontally in the opposite direction along slide rail 213, causing hook 211 to move horizontally in the opposite direction, thereby pulling the top of the hooked garbage bag to both sides, tearing a larger opening in the top of the garbage bag. When gear 215 rotates in the opposite direction, slider 212 and hook 211 return to their original positions, ready for the next bag-breaking action.

[0066] In one specific embodiment, the bag-cutting device 22 is fixedly installed on the inner wall of the box body 1, specifically located below the suspension plate 216 at the inner walls of the front and rear sides of the box body 1. (See reference) Figure 4 The bag-cutting device 22, when retracted, is embedded in a groove in the inner wall of the container 1 to avoid interfering with the operation of other mechanisms. The installation height of the bag-cutting device 22 corresponds to the lower side of the garbage bag, and the blade of the bag-cutting device 22 faces the direction in which the garbage bag falls. The bag-cutting device 22 and the bag-breaking device 21 work together through a pulling and cutting action. After the hook 211 tears open the top of the garbage bag, the bag-cutting device 22 cuts the garbage bag, completing the complete unloading of the entire bag of garbage and cutting off the remaining bag to prevent tangling.

[0067] For example, the bag cutting device 22 includes two bag cutting blades, which are symmetrically fixed on two oppositely distributed inner walls of the box 1 and located on the lower side of both sides of the bag breaking device 21. They can cut the garbage bag after the barb 211 tears open the top of the garbage bag.

[0068] It should be noted that the cutting action of the bag-cutting device 22 can be up-and-down or back-and-forth reciprocating cutting, and the specific cutting method can be adjusted according to the material and thickness of the actual garbage bag. Through the top pulling and tearing action of the barb 211 combined with the cutting action of the bag-cutting device 22, the entire garbage bag is completely broken open and cut, and the mixed garbage inside is released under gravity, falling into the garbage dispersion tray 31 below. Therefore, the combined bag-breaking structure can adapt to plastic garbage bags of different thicknesses and materials, realizing fully automatic bag-breaking processing of entire bags of garbage without manual assistance, significantly improving the automation level and operational efficiency of garbage sorting and processing.

[0069] Furthermore, the bag-breaking and cutting module 2 is equipped with a deceleration curtain 23 and an infrared sensor 217. The deceleration curtain 23 is fixedly installed on the upper side of the outlet of the garbage channel 5 and is positioned above the bag-breaking device 21. The deceleration curtain 23 can be made of polyester fiber industrial mesh fabric, which is flexible and wear-resistant, and its edges are treated with high-temperature locking to prevent it from coming undone or breaking. The deceleration curtain 23 decelerates the garbage bag through friction, preventing the garbage from passing the hook 211 of the bag-breaking device 21 too quickly. An infrared sensor 217 is fixedly installed on the lower side of the suspension plate 216, facing the outlet of the garbage channel 5. The infrared sensor 217 can detect whether the garbage bag is hooked by the hook 211. The detection signal is transmitted to the control system to provide a trigger signal for the start-up and action sequence of the bag-breaking device 21. When the garbage bag falls to the bag-breaking device 21, the infrared sensor 217 detects the garbage bag and triggers the bag-breaking action.

[0070] In this embodiment, the working stability and reliability of the bag-breaking and cutting module 2 are significantly improved through the coordinated operation of the deceleration curtain 23 and the infrared sensor 217. The deceleration curtain 23 ensures that the garbage bag can accurately stop in the bag-breaking working area, and the infrared sensor 217 ensures that the bag-breaking device 21 is activated. Together, they guarantee the success rate of automatic bag breaking of whole bags of garbage.

[0071] like Figure 5 As shown. In one specific embodiment, the oscillation drive device 32 includes an oscillation motor 321, a curved guide plate 324, a guide pin 326, and a swing arm 325. The oscillation motor 321 is fixedly mounted on the long cantilever plate 312. The oscillation motor 321 can receive electrical signals to achieve precise drive control. One end of the push rod 322 is connected to the output shaft of the oscillation motor 321, and the other end is fixedly connected to the push plate 323.

[0072] In addition, the waste dispersing plate 31 includes a short cantilever plate 311, a long cantilever plate 312, a frame 313, and an opening and closing plate 314. A curved guide rail 3111 is provided on the short cantilever plate 311, and a sliding column 315 is nested within the curved guide rail 3111. The frame 313 is slidably nested within the curved guide rail 3111 via the sliding column 315, thereby sliding horizontally back and forth along the curved guide rail 3111, providing support and guidance for the oscillating motion of the waste dispersing plate 31. The long cantilever plate 312 is used to fix and install the oscillation drive device 32, i.e., the oscillation motor 321 is fixedly installed on the long cantilever plate 312, ensuring a secure installation. Furthermore, the frame 313 is connected to the oscillation drive device 32, and power is transmitted to the curved guide plate 324 via the push rod 322 and the push plate 323, driving the curved guide plate 324 to perform horizontal reciprocating linear motion along the track 327. A curved guide plate 324 has a curved groove, within which a guide pin 326 is nested. The guide pin 326 can move along the curved groove. Since the guide pin 326 is fixedly connected to the swing arm 325, which is rotatably connected to the long cantilever plate 312 and fixedly connected to the waste dispersion disc 31, the reciprocating sliding of the guide pin 326 along the curved groove causes the swing arm 325 to swing freely around the hinge point within a certain angle range. This, in turn, drives the waste dispersion disc 31 to vibrate synchronously, achieving uniform dispersion of mixed waste within the bin and preventing waste overlap from affecting subsequent identification and grabbing operations. The remaining waste storage bin 33 is located below the opening and closing plate 314, which allows unidentified remaining waste to be released into the remaining waste storage bin 33.

[0073] like Figure 8 As shown. In one specific embodiment, the sorting trash can 61 includes a plurality of circumferentially distributed sector-shaped bins 612. Exemplarily, the number of sector-shaped bins 612 is set to four, each used to store a preset category of trash, such as hazardous waste, plastic waste, metal waste, and paper waste. Each sector-shaped bin 612 has a sector-shaped cross-section, and the four sector-shaped bins 612 form a complete or near-circular layout. This sector-shaped layout structure allows for the maximum number of sector-shaped bins 612 to be accommodated within a limited circular space, while all four sector-shaped bins 612 have a large effective volume.

[0074] The top of the fan-shaped bin 612 is integrally formed with a discharge leak-proof flare 611. The diameter of the discharge leak-proof flare 611 is larger than the diameter of the fan-shaped bin 612, and it is flared outward in the shape of a trumpet. When garbage falls from the top, the discharge leak-proof flare 611 can effectively prevent garbage from falling outside the fan-shaped bin 612 due to the deviation of the landing point, and prevent garbage from overflowing during disposal.

[0075] Furthermore, the three sides of each fan-shaped bin 612 adopt a large rounded corner structure, that is, the corners of the fan-shaped bin 612 adopt a smooth arc transition. Compared with the sharp corner structure, the large rounded corner structure can prevent garbage from getting stuck or remaining in the corners of the bin, allowing the garbage to slide smoothly to the bottom of the bin, and also making it easier to clean and maintain the bin.

[0076] In this embodiment, the rotating mechanism 62 drives the sorting bins 61 to rotate and reposition, adapting to the compression operation of the compression mechanism 63. Specifically, the rotating mechanism 62 includes a cross-shaped partition shaft 622 and a sector-shaped chassis 621. The cross-shaped partition shaft 622 is a vertically arranged shaft component with a cross-shaped cross-section, i.e., it has four partitions distributed at 90-degree angles. The four partitions divide the circular space into four independent sector-shaped areas, each of which can accommodate a sector-shaped bin 612. By separating the four sector-shaped bins 612 through the cross-shaped partition shaft 622, different types of waste are prevented from being mixed between the sector-shaped bins 612. Even during vibration or rotation, the waste in different sector-shaped bins 612 will not be cross-contaminated. In addition, a power input component is connected to the bottom of the cross-shaped partition shaft 622, thereby driving the cross-shaped partition shaft 622 to rotate.

[0077] In one specific embodiment, the bottom of the cross-shaped partition shaft 622 is fixedly connected to the sector-shaped base 621, and the two can be fixed together by welding, integral casting, or bolt fastening. The sector-shaped base 621 is a disc-shaped load-bearing component, the diameter of which is adapted to the outer diameter formed by the four sector-shaped barrels 612. The four sector-shaped barrels 612 are respectively snapped onto the sector-shaped base 621, and are arranged alternately with the four partitions of the cross-shaped partition shaft 622.

[0078] When the cross-shaped partition shaft 622 rotates, the sector-shaped base 621 rotates synchronously with the cross-shaped partition shaft 622, thereby driving the four sector-shaped bins 612 to rotate synchronously. By controlling the rotation angle of the cross-shaped partition shaft 622, any sector-shaped bin 612 can be precisely switched to the side directly below the compression mechanism 63, or switched to the side below the material drop position at the end of the waste conveyor belt 43.

[0079] Based on the recognition results of the vision recognition and grasping module 4 or the working requirements of the compression mechanism 63, the control system sends a rotation command to the power input component. The power input component drives the cross partition shaft 622 and the fan-shaped chassis 621 to rotate by a specified angle, thereby completing the precise and rapid switching of the barrel.

[0080] For example, the pressure sensor built into the rotating mechanism 62 and the infrared sensor on the inner wall of the container 1 monitor the capacity of the sorting trash cans 61 in real time. When the amount of trash in any sorting trash can 61 reaches a set threshold, the rotating mechanism 62 is activated, and the cross-shaped partition shaft 622 drives the fan-shaped chassis 621 to rotate, turning the sorting trash can 61 to the underside of the compression mechanism 63. Subsequently, the compression mechanism 63 is activated, and the second lead screw 633 rotates, causing the second lead screw nut 632 to move up and down vertically. Through the three support plates 635, the stainless steel compression plate 631 is driven to vertically compress the trash in the sorting trash can 61, reducing the volume of trash and improving the utilization rate of the storage space inside the container. After compression is completed, the compression plate 631 is reset, and the rotating mechanism 62 drives the sorting trash can 61 back to its original position.

[0081] When garbage needs to be emptied, open the front door 10 of the container 1, remove the sorting garbage bin 61 from the fan-shaped base 621, empty the garbage inside, and then reset the locking mechanism. Pull out the remaining garbage storage bin 33, clean out the garbage and wastewater inside, and then reset it. In this embodiment, the compression mechanism 63, in conjunction with the structure of the rotatable sorting bin assembly, can sequentially compress the multiple fan-shaped bins 612 of the sorting garbage bin 61. This compression solution significantly simplifies the equipment structure, reduces manufacturing costs and control complexity, and effectively solves the common problems of the sorting garbage bin 61 being either overfilled or underfilled, greatly improving the utilization rate of the internal storage space, reducing the frequency of garbage collection, and lowering subsequent maintenance costs.

[0082] like Figure 9 As shown. In one specific embodiment, the compression mechanism 63 includes a drive motor 636, a second lead screw 633, a second lead screw nut 632, and a compression plate 631. The drive motor 636 is fixedly mounted on the upper wall of the housing 1. The drive motor 636 can be a stepper motor, a servo motor, or a DC geared motor, the specific type of which is selected according to the required compression force and compression speed. The output shaft of the drive motor 636 is connected to the vertically arranged second lead screw 633. The bottom of the second lead screw 633 is fixedly supported to the inner wall of the housing 1 by a first connecting rod 634. The bottom support structure can ensure that the second lead screw 633 remains stable in the vertical direction and prevent the second lead screw 633 from bending and deforming under pressure.

[0083] Furthermore, the second lead screw nut 632 is fitted onto the second lead screw 633, and the internal thread of the second lead screw nut 632 is compatible with the external thread of the second lead screw 633. When the second lead screw 633 rotates under the drive of the drive motor 636, the second lead screw nut 632 reciprocates up and down along the axial direction of the second lead screw 633. The second lead screw nut 632 is fixedly connected to one end of the support plate 635, and the other end of the support plate 635 is fixedly connected to the compression plate 631.

[0084] To ensure the stability and uniform force distribution of the compression plate 631 during lifting and lowering, three support plates 635 are provided, arranged vertically on three sides to form a stable triangular support structure. This three-support-plates-635 structure effectively resists the eccentric load moment that may be generated during compression of the compression plate 631, preventing the compression plate 631 from tilting or jamming.

[0085] Furthermore, the compression mechanism 63 is equipped with a compression plate 631, which moves vertically downward under the drive of the drive motor 636, applying greater pressure to the garbage in the bin, compacting the loose garbage, and significantly reducing the volume of the garbage. After compression is completed, the compression plate 631 returns to its original position, and the rotating mechanism 62 then rotates the sorting garbage bin 61 to the preset position.

[0086] In one specific embodiment, the compression plate 631 is a flat plate with sufficient strength, and its shape and size are adapted to the shape and size of the opening of the sorting waste bin 61. The compression plate 631 can be made of stainless steel, which has good compressive strength and excellent corrosion resistance, and can withstand the compressive force generated during waste compression for a long time without deformation, and will not rust or be damaged due to contact with wet or corrosive waste. The lower surface of the compression plate 631 can be a flat plane, or it can be provided with protrusions or textures to enhance the compaction effect on the waste.

[0087] For example, when the drive motor 636 drives the second lead screw 633 to rotate, the second lead screw nut 632 moves up and down along the second lead screw 633, driving the compression plate 631 to rise and fall synchronously via the support plate 635. When it is necessary to compress the garbage in a certain type of garbage bin 61, the rotating mechanism 62 first rotates the garbage bin 61 to the side directly below the compression plate 631. Then the drive motor 636 rotates in the forward direction, the second lead screw 633 drives the second lead screw nut 632 to move downward, and the compression plate 631 moves downward accordingly, entering the interior of the garbage bin 61, applying vertical downward pressure to the garbage inside. Under the squeezing action of the compression plate 631, the loose garbage is compacted, the gaps between the garbage are greatly reduced, and the garbage volume is significantly reduced. The descent depth of the compression plate 631 can be controlled according to the actual looseness of the garbage and the remaining space inside the bin, stopping when the compression plate 631 descends to a certain height from the bottom of the bin or when the compression force detected by the pressure sensor reaches a set threshold. After compression, the drive motor 636 rotates in the opposite direction, and the second lead screw 633 drives the second lead screw nut 632 to move upward. The compression plate 631 is then lifted upward and retracts from the sorting waste bin 61, resetting to its initial position. The rotating mechanism 62 then rotates the compressed sorting waste bin 61 back to its original position, ready for the next waste disposal.

[0088] like Figure 9As shown. Furthermore, the compression mechanism 63 enables the garbage in each sector-shaped bin 612 of the classified garbage bin 61 to be compacted in a timely manner after accumulating to a certain amount, effectively solving the problems of the classified garbage bin 61 being either empty or hollow, making full use of the storage space inside the bin, reducing the frequency of garbage collection, and lowering the later operation and maintenance costs.

[0089] Furthermore, an insect-repelling and disinfecting lamp 14 can be installed on the upper side of the rotating mechanism 62. Specifically, the insect-repelling and disinfecting lamp 14 can be fixedly installed on the top of the cross-shaped partition shaft 622. The cross-shaped partition shaft 622 is located at the center of the entire sorting, compression, and storage module 6. Installing the insect-repelling and disinfecting lamp 14 on the cross-shaped partition shaft 622 allows the disinfecting lamp light to shine evenly in all directions, covering the upper space of the sorting bins 61 and the lower space of the compression mechanism 63, thereby improving the irradiation effect.

[0090] Furthermore, the insect-repelling and disinfecting lamp 14 may include LED beads of a specific wavelength, such as ultraviolet light beads, which have a strong repellent effect on mosquitoes. The insect-repelling and disinfecting lamp 14 can repel mosquitoes and has bactericidal capabilities, reducing odor production and improving sterilization effectiveness.

[0091] In one specific embodiment, the control method of the insect repellent and disinfection lamp 14 can be associated with the operating status of the equipment. During idle periods of the equipment, such as at night or when there is no garbage disposal for a long time, the insect repellent and disinfection lamp 14 can automatically turn on to continuously perform insect repellent and disinfection operations. When the human infrared sensor detects a person approaching, the insect repellent and disinfection lamp 14 can automatically turn off or reduce its power to avoid potential harm to the human body from ultraviolet light. When the equipment is performing garbage disposal operations normally, the insect repellent and disinfection lamp 14 can operate continuously at a low power, or intermittently during the rotation and compression of the garbage bin.

[0092] Based on the above embodiments, the trash can also includes multiple solar panels 12 and lithium-ion batteries 13, forming a photovoltaic self-powered system. Furthermore, the lithium-ion batteries 13 can also be charged or swapped via an external power source to ensure stable operation of the power supply system under various environmental conditions, making it energy-saving, environmentally friendly, and highly practical.

[0093] Exemplarily, the solar panel 12 is fixedly installed on the outer wall of the housing 1. Specifically, the solar panel 12 can be fixedly installed on the top and / or sides (e.g., at least one of the front, rear, left, and right sides) of the housing 1. A lithium-ion battery 13 is disposed inside the housing 1. Exemplarily, the lithium-ion battery 13 can be disposed on the side of the gear 215. The lithium-ion battery 13 is electrically connected to the solar panel 12 on the outside of the housing 1, forming a photovoltaic energy storage system, which provides power to the bag breaking and cutting module 2, the vibration separation module 3, the visual recognition and grasping module 4, and the sorting and compression storage module 6.

[0094] The aforementioned multi-faceted solar panels 12 can receive sunlight from different directions, improving power generation efficiency and total power generation. Solar panels 12 can be photovoltaic solar panels to ensure photoelectric conversion efficiency.

[0095] Furthermore, the insect-repelling and disinfecting lamp 14 can be powered by a lithium-ion battery 13. The solar energy collected by the solar panel 12 is converted into electrical energy and stored in the lithium-ion battery 13, providing continuous power support for the insect-repelling and disinfecting lamp 14. Even in environments with insufficient light, the lithium-ion battery 13 can maintain the normal operation of the insect-repelling and disinfecting lamp 14 by charging through an external power source or by battery swapping, ensuring that the equipment maintains good hygiene under various environmental conditions.

[0096] In summary, this application provides an automatic bag-breaking intelligent sorting and compressing garbage bin. It employs a combined bag-breaking and cutting device: a hook 211 hooks the top of the garbage bag, which, in conjunction with a symmetrical bag-cutting device 22 on the front and rear inner walls of the bin body 1, cuts the bag body. Combined with a deceleration curtain 23 to prevent over-hook, it achieves fully automatic bag breaking and unloading of the entire bag of garbage. The oscillation separation module 3 in this application, based on a horizontal oscillation structure linked by a curved guide rail 3111, guide pin 326, and swing arm 325, drives the garbage dispersion disc 31 to oscillate reciprocally, evenly dispersing mixed garbage and improving garbage identification accuracy. In this solution, the mechanical claw head 4230 has a flexible part 4232 inside, combined with a rigid part 4231 on the outside, enabling differentiated gripping of lightweight soft garbage and hard, irregular garbage. The anti-slip texture 4233 on the top further enhances gripping stability. Furthermore, this solution employs a sorting-then-separating waste sorting method. First, visual recognition and a mechanical claw 422 grab the waste of preset categories. Then, the opening plate 314 opens to release the remaining waste that was not grabbed, achieving precise separation. Additionally, this solution uses a single compression mechanism 63 paired with a rotating sorting bin assembly. Rotation moves the full bin to the compression position for compaction, solving the problems of empty bins and underfilled bins, thus improving storage space utilization.
