Description

Technical Field

[0001] The invention relates to garbage recycling, and in particular to an intelligent garbage classification and recycling method. Background Art

[0005] The traditional method of garbage classification is mainly based on manual classification, which is difficult to achieve by relying on the autonomy of citizens. Setting up garbage sorters requires a lot of human resources, which is costly and threatens the lives of garbage sorters. With the continuous progress of society, it is necessary to design an intelligent garbage classification and recycling method that is convenient for garbage classification and recycling, reduces recycling operation costs, and enhances social image and sense of belonging. Summary of the invention

[0006] The present invention aims to solve at least one of the above-mentioned technical problems, provide an intelligent garbage sorting and recycling method, reduce recycling operation costs, and reduce the threat of garbage sorting to the public.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is:

[0008] An intelligent garbage classification and recycling method, comprising the following steps:

[0009] Garbage receiving, the garbage falls into the buffer bucket, and then falls at the beginning of the corresponding transmission display belt through the buffer bucket;

[0010] The garbage is spread out, and in the process of the conveyor display belt conveying the garbage at its beginning to the bottom of the camera, at least two soft material shifting parts spread out the garbage, and the garbage is scattered and displayed on the conveyor display belt;

[0011] Garbage identification: the camera takes the actual image of each piece of garbage below it when it is presented on the conveyor display belt. The central processor compares the actual image with the teaching garbage pattern set called in the buffer to determine the attributes of each piece of garbage, the position of each piece of garbage on the conveyor display belt, and the sorting order of each piece of garbage;

[0012] Sorting and delivery. According to the garbage identification results, the central processor determines that each type of garbage should be sorted into the garbage bin with the corresponding attribute. Paper and plastic are moved into the paper and plastic recycling bin by the sorting robot, glass and ceramic parts are moved into the glass recycling bin by the sorting robot, the non-recyclable non-kitchen waste on the transmission display belt corresponding to the kitchen waste label is moved into the non-recyclable non-kitchen waste sub-bin by the sorting robot, the kitchen waste on the transmission display belt corresponding to the kitchen waste label is poured into the kitchen waste main bin via the transmission display belt, the kitchen waste on the transmission display belt corresponding to the non-kitchen waste label is moved into the kitchen waste sub-bin by the sorting robot, and the non-recyclable non-kitchen waste on the transmission display belt corresponding to the non-kitchen waste label is poured into the non-recyclable non-kitchen waste main bin via the transmission display belt.

[0013] Compared with the existing technology, the beneficial effects of this application include: no need for volunteers to be on duty, garbage can be sorted as it is thrown away, and intelligent screening methods can quickly divert various types of garbage, reducing the operating costs of garbage sorting and recycling, alleviating the pressure on citizens to sort garbage, and substantially realizing the recyclability of domestic waste.

[0014] As a further improvement, the garbage spreading step also includes a bag breaking step. When a material level sensor detects that a new portion of garbage is put into the buffer bucket, the transmission display belt runs in the reverse direction, causing the garbage bag in the buffer bucket to hit a second bag breaking hook pointing obliquely downward, and the garbage bag is pierced by the second bag breaking hook. The garbage in the garbage bag slides and crowds along the second bag breaking hook, causing the garbage bag to be lifted up and broken by the hook.

[0015] As a further improvement, in the bag breaking step, the bag-lifting frame performs multiple bag-lifting and bag-breaking operations, so that the garbage bags in the buffer bucket are broken by the second bag-breaking hook and the third bag-breaking hook.

[0016] As a further improvement, in the garbage spreading step, the top bag frame is repeatedly raised and lowered so that the loose garbage sinks to the bottom buffer bucket before the garbage bags, and the loose garbage sinks to the bottom buffer bucket before the garbage bags.

[0017] As a further improvement, in the bag breaking step, when the top bag rack starts to rise, the conveying display belt stops running. In the bag breaking step, the top bag rack performs multiple top bag breaking operations to allow the filtrate to be fully discharged. The downward pressure of the top bag rack is suitable for filtering the liquid in the garbage, and the vibration of the garbage is suitable for accelerating the discharge of the filtrate.

[0018] As a further improvement, in the bag breaking step, the bag lifting frame performs one or more bag breaking operations, and the lower end of the broken garbage bag is shaken and / or vibrated to disperse the garbage.

[0019] As a further improvement, in the garbage spreading step, the garbage scattered in the buffer bucket is spread out by vibration, and the garbage transferred from the buffer bucket to the bottom of the camera is spread out by vibration and sweeping.

[0020] As a further improvement, in the garbage spreading step, the top bag frame is repeatedly raised and lowered, the transmission display belt vibrates, and the top bag frame descends to press the garbage in the buffer bucket.

[0021] As a further improvement, in the sorting and delivery step, after paper, plastic and glass are sorted and the main garbage corresponding to the transmission display belt is dumped, the metal garbage is transferred to the metal recovery box by magnetic attraction.

[0022] A further improvement includes a cleaning step, wherein the first nozzle is suitable for spraying cleaning liquid toward the conveying display belt and / or the roller brush, the roller brush is suitable for sweeping the material transfer surface of the lower section of the conveying display belt, and the sewage from the conveying display belt and / or the roller brush is suitable for falling into the sewage collection tank.

The paper and plastic recycling bin 730 is suitable for transmitting kitchen waste to the corresponding kitchen waste. 20. The glass recycling box 730 and the non-recyclable non-kitchen waste sub-box 740 are suitable for being moved into the corresponding garbage by the corresponding sorting robot. The non-recyclable non-kitchen waste main box 750, the paper and plastic recycling box 720, the glass recycling box 730, the kitchen waste sub-box 760, and the corresponding sorting robot together surround the corresponding transmission display belt 200. The non-recyclable non-kitchen waste main box 750 is suitable for being transferred into the non-recyclable non-kitchen waste by the corresponding transmission display belt 200. The paper and plastic recycling box 720, the glass recycling box 730, and the kitchen waste sub-box 760 are suitable for being moved into the corresponding garbage by the corresponding sorting robot.

[0036] Preferably, the harmful collection box also includes a harmful collection box, which and the corresponding multiple garbage bins 700 together surround the tail end of the corresponding transmission display belt 200.

[0037] It can be understood that the transmission display belt 200 includes a conveyor belt, at least two pulleys, and a motor connected to at least one pulley. Figures 2 to 4 Preferably, the conveying display belt 200 is integrally formed with a side baffle 211; and / or the chassis 100 is provided with a baffle plate for blocking the side end of the conveying display belt 200, and the baffle plate and the conveying display belt 200 together define a channel suitable for garbage transmission and display.

[0038] It is understandable that the central processing unit controls peripheral devices such as screens, cameras, motors, speakers, lights, etc. through RS232, RS485, infrared, network and other protocols. The central processing unit can be a microcontroller (i.e., MCU, such as STM32 series microcontrollers, PIC series, LPC series, MSP430 series, RX series, PSoC series, ESP8266 and ESP32), CPU controller (such as Intel, AMD, ARM).

[0039] In some embodiments of the present invention, the Raspberry Pi 4B (Raspberry Pi 4th generation) used is equipped with the official Raspbian system (an operating system specially designed for Raspberry Pi), and Raspberry Pi 4B uses Broadcom BCM2711 quad-core processor (i.e., central processing unit, Raspberry Pi processor), a 64-bit quad-core ARM Corex-A72 processor, with a clock speed of 1.5 GHZ (i.e., the highest main frequency can reach 1.5 GHz), including a VideoCoreV GPU; Broadcom BCM2711 is manufactured using a 28 nanometer process, supports up to 8GB of LPDDR4 RAM, supports Bluetooth 5.0, USB 3.0, Gigabit Ethernet and 4K video decoding and encoding. Raspberry Pi 4B can run various operating systems, such as Raspbian, Ubuntu2, Windows 10l0T Core, etc., and has a wide range of application fields, such as embedded systems, Internet of Things devices, home media centers, etc. Raspberry Pi 4B has powerful code execution capabilities and rich controller applications, which makes the neural network algorithm smoothly applied in garbage sorting.

[0040] In the present invention, the selected high-definition camera 500 is connected to the central processor via a USB interface, and the identified garbage image data is quickly transmitted back to the central processor for analysis and processing; after identifying the type of garbage, the central processor outputs instructions to the sorting manipulator through the GPIO interface, thereby controlling the picking and delivery of different types of garbage, presenting AI intelligent automatic classification. The Raspberry Pi processor (central processor) is connected to the cloud server through its own WiFi module / 4G or 5G data module / network cable module, and uploads the data obtained by each module such as the surveillance camera and the capacity sensor to the cloud server, which facilitates the host terminal (remote control room computer) to obtain relevant data so that the administrator can do the next step of processing.

[0041] Specific algorithms may include: (1) opening the video device file, initializing the video acquisition parameters, and setting the format of the video image; (2) applying for a frame buffer for acquiring video images, and mapping these applied frame buffers from the kernel space to the user space; (3) placing the applied buffer into the video acquisition input queue for acquiring video image data; (4) taking the frame buffer out of the queue, processing the video image data, and then placing the frame buffer back into the queue; (5) looping the above four steps in sequence to continuously obtain video image data; (6) closing the video device file to end video acquisition.

[0042] Data transmission is performed under the TCP / IP communication protocol of the Raspberry Pi, and the collected data is sent to the cloud server; using the Python compilation environment, the Socket third-party library is used to realize data transmission. Socket programming is divided into the following five steps: (1) Create a Socket object and set SOCK_STREAM to TCP type; (2) Get a static IP, bind the IP and port, and use listen() to listen; (3) Use the accept() function to receive the request sent by the Client, including the Client's IP and port; (4) Send the real-time data of the trash can to the Client; (5) Use the clock to set the timing loop function to realize real-time data update.

[0043] Reference Figure 8 , the mobile phone App signal connects to the cloud server to monitor the geographical location information and capacity information of the garbage bin 700. The Beidou GPS-ATK1218-BD module can be used to detect the geographical location information; the garbage bin capacity information detection (capacity sensor) and the material level sensor 330 of the buffer bucket 300 use the HY-SRF05 ultrasonic module.

[0044] Reference Figures 2 to 4Because the soft material-selecting member 410 is used to sweep and spread out the garbage being transported, and the camera 500 is used to image the spread-out garbage on the transport display belt 200, the buffer bucket 300, the soft material-selecting member 410, the camera 500 and the sorting robot are sequentially arranged along the transport direction of each transport display belt 200.

[0045] Different garbage has different heights, and the garbage pile is spread out during transportation. In order to ensure that the higher garbage that has landed on the transportation display belt 200 has little or no slippage when being swept, at least two soft material-sweeping members 410 with gradually lower heights are arranged in sequence along the garbage transportation direction; further, the soft material-sweeping member 410 can be a piece of cloth or a soft brush.

[0046] Preferably, the soft material-dispensing member 410 is a plurality of bundles of soft bristles arranged at intervals, that is, a plurality of bundles of individual soft bristles are arranged in the soft material-dispensing member 410, and the arrangement direction of the plurality of bundles of soft bristles is perpendicular to the transmission direction of the transmission display belt 200. The plurality of bundles of individual soft bristles can respectively sweep the scattered and disordered garbage, so that the garbage that moves in the same row and has different pile heights can be spread out. The single soft material-dispensing member 410 is provided with one or more rows of soft bristles, which is equivalent to replacement, and each row of soft bristles has multiple bundles arranged as above.

[0047] It is understandable that each transmission display belt 200 is configured as one or more transmission belts, which is an equivalent replacement in transmission display. Figure 1 and Figure 2 The back panel of the chassis 100 is detachable and / or is suitable as a rear door panel, and the rear end of the chassis 100 is suitable for disassembling and assembling the multiple trash bins 700; when one or more trash bins 700 are full, open the back of the chassis 100 and replace or clean the trash bins 700.

[0048] Reference Figure 2 , Figure 6 , an intelligent garbage classification and recycling method, including a garbage receiving step, a garbage spreading step, a garbage identifying step, and a garbage sorting and delivery step.

[0049] The garbage is received and falls into the buffer bucket 300, and then piled up at the beginning of the corresponding transmission display belt 200 through the buffer bucket 300; Figures 2 to 4The left and right sides and the front side panels of the buffer bucket 300 stop the garbage and prevent the garbage from collapsing from the beginning of the transmission display belt 200. Among them, citizens with a strong sense of classification can accurately put the garbage into the corresponding buffer bucket 300 and the transmission display belt 200 according to the kitchen waste mark 110 and the non-kitchen waste mark 120, which effectively reduces the work of the sorting manipulator, reduces the amount of garbage sorting in the recycling station, and improves the garbage sorting efficiency of the recycling station. Citizens with a weak sense of classification can put the garbage into the buffer bucket 300 corresponding to the kitchen waste mark 110 or the buffer bucket 300 corresponding to the non-kitchen waste mark 120. The recycling station will control the sorting manipulator to sort and put the garbage according to the recognition of the camera 500.

[0050] The garbage is spread out. When the conveying display belt 200 conveys the garbage at its starting end to the bottom of the camera 500 , at least two soft material-pickling members 410 spread out the garbage, and the garbage is scattered and displayed on the conveying display belt 200 .

[0051] Garbage identification, the camera 500 takes actual images of the garbage below it when it is presented on the conveyor display belt 200, and the central processing unit compares the actual image with the teaching garbage pattern set called in the buffer to determine the attributes of each garbage, determine the position of each garbage on the conveyor display belt 200, and determine the sorting order of each garbage. Specifically, in the storage of big data teaching / big data examples, each pattern of the teaching garbage pattern set is photographed and stored when one or more garbage is displayed on the conveyor display belt 200, and the information of each pattern includes the attributes and position of each garbage therein; the central processing unit uses big data comparison to compare the garbage in each pattern of the teaching garbage pattern set with the actual garbage image one by one to find the example with the most appropriate attributes and position, and establish the position and attributes of the example as the position and attributes of the actual garbage; in AI sorting, the attributes of each garbage include sorting category attributes (kitchen waste, paper and plastic, glass, non-recyclable non-kitchen waste) and daily necessities attributes (bottles, paper, plastic, bowl pieces, etc.). Reference Figures 2 to 4 ,For the sorting order, it can be that after determining the position, sorting can be first left and then right, or first right and then left, or first right and then front.

[0052] Sorting and delivery. According to the garbage identification result, the central processor determines that each garbage should be sorted into the garbage bin 700 with the corresponding attribute. Paper and plastic are moved into the paper and plastic recycling bin 720 by the sorting robot, and glass and ceramic parts are moved into the glass recycling bin 730 by the sorting robot. The non-recyclable non-kitchen waste on the transmission display belt 200 corresponding to the kitchen waste mark 110 is moved into the non-recyclable non-kitchen waste sub-bin 740 by the sorting robot. The kitchen waste on the transmission display belt 200 corresponding to the kitchen waste mark 110 is poured into the kitchen waste main bin 710 via the transmission display belt 200. The kitchen waste on the transmission display belt 200 corresponding to the non-kitchen waste mark 120 is moved into the kitchen waste sub-bin 760 by the sorting robot. The non-recyclable non-kitchen waste on the transmission display belt 200 corresponding to the non-kitchen waste mark 120 is poured into the non-recyclable non-kitchen waste main bin 750 via the transmission display belt 200.

[0053] Because each piece of garbage is put into the buffer bucket 300, the buffer bucket 300 is slightly larger than a civilian garbage can / garbage bag. For example, the conventional buffer bucket 300 with a length and width of 350mm×350mm as shown below is slightly larger than a conventional civilian garbage can / garbage bag with a diameter of 250mm. When two pieces of garbage are put into the buffer bucket 300 and ideally spread out as much as possible, the distance between the two pieces of garbage is 170mm=350mm / 2. Therefore, when a small amount of garbage is put into the 350mm×350mm buffer bucket 300, so that the continuously spread garbage is relatively scattered, the distance between the garbage is generally ≤170mm, that is, the maximum distance between the garbage is 170mm. Therefore, after the camera 500 captures the starting point and end point of a piece of garbage, if no new garbage is recognized at a distance of 170mm or more, it is considered that the camera 500 has captured a complete piece of garbage. For another new batch of garbage, the material level sensor 330 / proximity switch in the buffer bucket 300 fails to detect the garbage again, and the camera 500 captures a complete batch of garbage, which is considered to have completed the identification / entry of the garbage, that is, the attributes and location data of each sample of the garbage are entered into the memory / cloud platform of the central processor.

[0054] Considering the actual factors in the design and development of sorting, the height of the sorting robot relative to the conveying display belt 200 is ≥50cm when working, the camera 500 is generally higher than the sorting robot, and the height of the camera 500 relative to the conveying display belt 200 is correspondingly ≥50cm. The actual wide-angle of the camera 500 is generally 60-140, so the visual range of the camera 500 is φ≥57.7cm, which is much larger than the maximum distance between garbage of 170mm.

[0055] In the present invention, scattered kitchen waste, light kitchen waste or non-kitchen waste, and flat waste can be sorted by suction nozzles and suction cups; slightly larger kitchen waste, such as chicken legs, vegetables, and meat pieces, can be sorted by claws. For meat slices, rice grains, nuts, and paper scraps ≤30 mm, a suction nozzle is used for sorting. The suction nozzle is divided into an inward cavity and an outward cavity by a filter. The air pump connected to the suction nozzle is suitable for adsorbing garbage and also for backblowing garbage; that is, the nuts and rice grains buffered in the outward cavity can be fully backblown to be discharged from the suction nozzle and put into the main kitchen waste box 710 or the auxiliary kitchen waste box 760. Preferably, the suction nozzle and the suction cup are provided with a soft bag ring lip suitable for attaching garbage. The inner circle of the soft bag ring lip is a trumpet mouth. For garbage with irregular surfaces and different lengths and widths, the soft bag ring lips of the suction nozzle and the suction cup can adsorb them. Preferably, the circumferential wall of the inner ring of the soft bag ring lip is provided with a steel wire layer, a metal wear-resistant layer, or a silicon carbide layer, etc., which effectively avoids cutting damage to the glass ceramics.

[0056] The sorting manipulators are all dual-arm manipulators, for example, refer to the dual independent manipulator design on the following webpage: https: / / www.bilibili.com / video / BV1Wb421n795 / ?vd_source=8fa4f394646f72df68338dc78a477e90. Preferably, the dual-arm manipulator of the present invention includes a suction manipulator and a claw manipulator. For scattered garbage with a relatively concentrated distribution, such as tea leaves, the claw manipulator can be used for sorting first, and then the suction manipulator can be used for sorting.

[0057] Kitchen waste is difficult to spread out. According to the time calculation for spreading out a full bag of kitchen waste in a conventional garbage bag (combined with sweeping and other methods), the full bag of waste undergoes t time of spreading (i.e., n sweepings within t time, or even combined with other spreading methods) to complete the spreading. For example, a full bag of waste undergoes vibration and 2 sweepings within 20 seconds to complete the spreading. Because the distance between the camera 500 and the corresponding buffer bucket 300 is designed to be l, the maximum transmission speed of the conveyor display belt 200 is V=l / t. On the other hand, the central processor plans the time it takes for the sorting robot to sort the garbage according to the amount of garbage per unit length of the conveyor display belt 200 captured by the camera 500, that is, plans the transmission speed V of the conveyor display belt 200. 计 (V 计 = the unit length divided by the sorting time). When the garbage is less, V 计 > V, the transmission display belt 200 is transmitted according to V; when there is a lot of garbage, V 计 When <V, the transmission display belt 200 is V 计 Therefore, when the first batch of garbage is being sorted and the second batch of garbage has just been moved out of the buffer bucket 300 and begins to spread out, the conveyor display belt 200 is at V and V 计 The smallest operation in the industry allows the garbage to be fully spread out and displayed.

[0058] In some embodiments, the monitoring head (i.e., monitoring camera, monitoring camera) checks the buffer bucket 300, for example, whether the buffer bucket 300 is covered / sealed by large garbage / large bag garbage, etc., to avoid the normal sorting and recycling work of the recycling station being hindered. The diameter and height of daily garbage bins / civilian garbage bins are generally 250mm, and the diameter of daily garbage bags is generally 250mm. The buffer bucket 300 of the present invention is about 350mm×350mm. Garbage with at least one side larger than 300mm is defined as large garbage, such as cardboard boxes, wooden tables and chairs, large glass pieces, pipes and rods, etc.; refer to Figure 1 , the front wall of the recycling station chassis 100 is provided with relevant slogans, such as "Please dispose of construction waste according to law, it is forbidden to dump construction waste into this station", "Garbage with at least one size larger than 30 cm is large garbage, please store large garbage in the large garbage room / large garbage room next to it". When the feed port of the buffer hopper 300 is blocked by abnormal objects such as large garbage and large bags of garbage, the sorting work is hindered, and the remote worker quickly disposes of the obstruction according to the monitoring video.

[0059] The present invention is applicable to public places such as residential areas, scenic spots, campuses, high-speed rail stations, airports, parks, etc., and construction waste is prohibited from being thrown in, and large pieces of garbage are prohibited from blocking the buffer bucket 300. Compared with the prior art, there is no need for volunteers to be on duty, and the garbage can be sorted as it is thrown. The intelligent screening method allows various types of garbage to be quickly diverted, reduces the operating cost of garbage classification and recycling, reduces the pressure on citizens to sort garbage, and substantially realizes the recyclability of domestic garbage.

[0060] To avoid the transmission display belt 200 from continuously operating, and to avoid the transmission display belt 200 from having no substantial work, so as to save electricity. Figure 6 The buffer 300 is provided with a material level sensor 330 / proximity switch suitable for detecting whether there is garbage piled therein. When the material level sensor 330 / proximity switch detects that there is garbage piled in the buffer 300, or the camera 500 has not finished shooting the garbage being identified, or the tail end of the conveyor display belt 200 has not finished sorting the garbage being sorted, the conveyor display belt 200 keeps transmitting, otherwise the conveyor display belt 200 stops operating. It can be understood that the conveyor display belt 200 is actually the material support bottom of the buffer 300, and the material level sensor 330 / proximity switch actually detects whether there is garbage piled on the conveyor display belt 200 in the buffer 300.

[0061] Reference Figure 7Specifically, the material level sensor 330 may detect the garbage pile height of the buffer bucket 300 using ultrasonic waves or light waves. When the transmission display belt 200 is smooth, the distance between the material level sensor 330 and the material level sensor 330 is H, that is, the capacity H, and the propagation speed of the ultrasonic wave / light wave is a constant, and the corresponding ultrasonic wave / light wave round-trip time is T0; further considering the actual / irrational / rational, the transmission display belt 200 is allowed to adhere to a stubborn garbage layer with a height of h, such as h=3mm, and the transmission display belt 200 is allowed to adhere to a stubborn oil sludge layer ≤3mm. For the round trip distance (Hh), the ultrasonic wave / light wave round-trip time is T1, so the actual detection threshold of the material level sensor 330 is T1; when the distance between the upper surface of the garbage piled on the transmission display belt 200 and the material level sensor 330 is <(Hh), the ultrasonic wave / light wave round-trip time is <T1, that is, the material level sensor 330 determines that there is garbage on the transmission display belt 200 in the buffer bucket 300, the transmission display belt 200 is started, the camera 500 is started, and the sorting robot is ready.

[0062] Reference Figure 1 In some embodiments, the chassis 100 is hinged with a cover plate 130, and the cover plate 130 is suitable for covering the feed openings of the buffer bucket 300 one by one. Furthermore, the cover plate 130 is opened and closed by the citizens themselves. In some designs, the chassis 100 is provided with an opening and closing mechanism suitable for opening and closing the cover plate 130, such as a cylinder body for opening or closing the cover plate 130, such as an opening and closing motor for driving the cover plate 130 to rotate.

[0063] Preferably, the chassis 100 is provided with a locking structure suitable for locking the cover 130 into a closed state, such as electromagnet adsorption, lock tongue buckle, etc. When the material level sensor 330 / proximity switch detects that there is garbage piled in the buffer bucket 300 and the transmission display belt 200 is started (forward or reverse circulation rotation), the cover 130 locks the feed port of the buffer bucket 300 into a closed state. When the material level sensor 330 detects that there is no garbage in the buffer bucket 300, the central processor starts timing. After timing t0, for example, t0=10s, the central processor drives the locking structure to release the cover 130, and the citizen can put a new portion of garbage into the buffer bucket 300 again. After the cover 130 is opened, the citizen can immediately put garbage into the buffer bucket 300. For the embodiment of the recycling station with automatic bag breaking, when the receiving time difference of two portions of garbage is short, the two portions of garbage may be spread as a continuous portion of garbage on the transmission display belt 200, or may be spread as two portions of garbage with a short distance interval.

[0064] In practice, based on the volume of daily / civilian trash cans, it usually takes no more than 2 minutes to spread out the trash, and the sorting time of the sorting robot usually does not exceed 2 minutes. Figure 1The front wall of the chassis 100 is provided with a relevant guide message "When the previous batch of garbage is being sorted, the cover 130 will be temporarily closed for no more than 2 minutes, please pay attention to the indicator light". For example, the indicator light indicating whether the cover 130 can be opened, each indicator light corresponds to the cover 130 one by one, and the indicator light is on, which means that the cover 130 cannot or can be opened; further, the front wall of the chassis 100 is provided with a digital screen suitable for displaying the remaining time of the cover 130 being locked, and the "countdown" of the digital screen corresponds to the remaining locking time of the cover 130.

[0065] Preferably, the recycling station is provided with at least two units, each unit includes a conveying display belt 200 corresponding to a food waste mark 110 and a conveying display belt 200 corresponding to a non-food waste mark 120; it can be understood from the above that each unit also includes a buffer bucket 300, a soft material selection member 410, a camera 500, a sorting robot, and a trash bin 700 corresponding to each conveying display belt 200. In the present invention, when the buffer bucket 300, the conveying display belt 200, the soft material selection member 410, the camera 500, and the sorting robot corresponding to a food waste mark 110 are performing garbage processing, the buffer bucket 300 with another food waste mark 110 can immediately put in garbage, or will soon be able to put in garbage, which greatly avoids citizens waiting at the recycling station; the same applies to the waiting time for the delivery of non-food waste.

[0066] In some embodiments, the recycling station requires citizens to dump garbage into the buffer bucket 300 through a trash can after reaching the recycling station, and / or requires the garbage bag to be opened and the garbage to be poured into the buffer bucket 300, so that various garbage is scattered into the buffer bucket 300, wherein the garbage bag is a package formed by the garbage bag enveloping the garbage. For example, in places such as shopping malls and high-speed rail stations, the garbage cans are far away and the garbage bags are much larger than those for civilian / household use. The recycling station requires staff to pour garbage into the buffer bucket 300 through a trash can or a garbage bag to avoid large bags of garbage covering the feed port of the buffer bucket 300. Specifically, there may be relevant slogans set on the front wall of the recycling station chassis 100, such as "To facilitate the equipment to classify garbage, please pour the garbage into the garbage entrance", "It is forbidden to directly insert large garbage bags (packages formed by garbage bags enveloping garbage) into the garbage entrance, please pour the garbage into the garbage entrance". The recycling station is equipped with multiple units, which greatly adapts to large garbage cans in public places, and the staff divides a large amount of garbage in the garbage can into multiple corresponding buffer buckets 300.

[0067] In reality, citizens fail to unpack and dump garbage bags due to factors such as trouble, danger, dirtiness, tight binding, and young age. Figure 3 , Figure 5In some embodiments, a garbage recycling bag breaking mechanism includes a buffer bucket 300, wherein the upper end of at least one inner wall of the buffer bucket 300 is provided with a first bag breaking row 310, wherein the first bag breaking row 310 includes a plurality of first bag breaking hooks 311 arranged horizontally, and the first bag breaking hooks 311 are suitable for breaking the garbage bag moving upward in the buffer bucket 300. When citizens carry the garbage bag to the recycling station, they first hang the garbage bag into the buffer bucket 300, and then lift the garbage bag upward, so that the garbage bag is broken (hooked and split) by one or more bag breaking hooks, so that the kitchen waste or non-kitchen waste in the garbage bag can be dispersed, and citizens do not need to manually untie and tear the bag, so that the garbage in the bag can be fully dispersed, so as to avoid dirtying hands with kitchen waste when untying the garbage bag, and avoid hurting hands with glass nails and blades when untying the bag, etc. The spacing between the bag breaking hooks is preferably set to 30-110mm, such as 40, 50, 60, or 70mm. The garbage bag can be broken by at least two bag breaking hooks, the garbage bag is fully broken, the garbage bag is broken into at least two pieces, the garbage bag breakage rate is high, and the garbage in the bag is fully scattered out.

[0068] In practice, citizens failed to untie the garbage bags due to time constraints and other considerations, and also failed to break the garbage bags through the first bag breaking row 310. Figure 3 , Figure 5 In some embodiments, a second bag-breaking row 320 is further included. The lower end of the inner wall of the buffer 300 facing the rear end of the conveying display belt 200 is provided with a second bag-breaking row 320. The second bag-breaking row 320 includes a plurality of second bag-breaking hooks 321 arranged horizontally. The second bag-breaking hooks 321 protrude downwardly. The conveying display belt 200 is suitable for reversely driving the garbage bag to hit the second bag-breaking hooks 321, so that the garbage bag is broken by the second bag-breaking hooks 321. For details, refer to Figures 2 to 4 , the conveyor display belt 200 runs in the reverse direction, that is, the garbage bag in the buffer bucket 300 moves from the back to the front, causing the garbage bag to hit the inclined second bag-breaking hook 321, and the second bag-breaking hook 321 pierces the garbage bag; in addition, because the second bag-breaking hook 321 is an inclined hook, the garbage in the garbage bag is squeezed along the second bag-breaking hook 321 during the reverse movement (backward movement), causing the garbage bag that has been hooked to be lifted up by the garbage squeezed on it, causing the garbage bag to be hooked and split. On the other hand, the second bag-breaking hook 321 protrudes downward and tilted toward the side where the camera 500 is located, and the garbage scattered into the buffer bucket 300 is guided by the second bag-breaking hook 321 and concentrated to the rear of the inner chamber of the buffer bucket 300.

[0069] Before the garbage spreading step, there is also a bag breaking step. The material level sensor 330 detects that a new portion of garbage is put into the buffer bucket 300, and the conveying display belt 200 rotates in the reverse direction, so that the garbage bag in the buffer bucket 300 hits the second bag breaking hook 321 pointing obliquely downward, and the garbage bag is pierced by the second bag breaking hook 321. The garbage in the garbage bag slides up and crowds along the second bag breaking hook 321, so that the garbage bag is lifted up and is hooked and broken. Among them, because the second bag breaking hook 321 points obliquely downward, the hook tip of the second bag breaking hook 321 forms a gorge with the conveying display belt 200, and the garbage in the garbage bag is basically squeezed above the second bag breaking hook 321, so that the garbage bag is pulled up by the crowded garbage, and the garbage bag contains a movement tendency that is not along the axial direction of the second bag breaking hook 321, so that the garbage bag is hooked and pulled and torn.

[0070] In practice, citizens may first pour in loose garbage, and then put in a whole bag of garbage, or citizens may put in multiple bags of garbage at the same time. Only relying on the second bag breaking row 320 and the conveying display belt 200, all the garbage bags at that time cannot be completely broken. In practice, the oily and smooth conveying display belt 200 is difficult to drive the garbage bags to move in the opposite direction; in addition, the oily and smooth conveying display belt 200 is suitable for solving the efficiency problem of vibrating material spreading, but the garbage on the oily and smooth conveying display belt 200 is prone to slipping due to sweeping. In some embodiments, the conveying surface of the conveying display belt 200 is arranged with multiple push plates 212 at intervals along the axial direction.

[0071] Reference Figures 2 to 4 In some embodiments, a bag lifting frame 421 and a bag breaking and lifting cylinder 422 for driving the bag lifting frame 421 to rise and fall are further included. The bag breaking and lifting cylinder 422 is suitable for lifting the garbage bag that has been punctured by the second bag breaking hook 321 through the bag lifting frame 421. The lifting direction of the bag lifting frame 421 deviates from the axial direction of the second bag breaking hook 321, so that the garbage bag is fully and quickly torn apart, and the garbage in the bag is fully scattered on the conveying display belt 200. It can be understood that the bag breaking and lifting cylinder 422 is essentially a cylinder, a hydraulic cylinder or an electric cylinder. In the bag breaking step, the bag lifting frame 421 is suitable for lifting the garbage bag that has been punctured by the second bag breaking hook 321, so that the garbage bag is torn apart by one or more second bag breaking hooks 321. Specifically, since the size of the buffer bucket 300 is 350mm×350mm, and the garbage bag is φ250mm, that is, the maximum distance between the outer wall of the garbage bag and the inner wall of the buffer bucket 300 is 350-250=100mm, the reverse distance of the conveyor display belt 200 does not exceed 100mm, that is, the garbage bag can be pierced by the second bag-breaking hook 321; the conveyor display belt 200 reverses at a predetermined speed, so after the conveyor display belt 200 rotates in the reverse direction for a predetermined time, the garbage bag is pierced by the second bag-breaking hook 321, and then the bag-top frame 421 starts to rise. Figure 3 and Figure 4 The top bag frame 421 is provided with a climbing guide slope suitable for the garbage bag to climb on.

[0072] Reference Figures 2 to 4In actual design considerations, the actual bag-lifting beam of the bag-lifting frame 421 needs to span the conveying display belt 200, the bag-breaking and lifting cylinder 422 needs to be set below the conveying display belt 200, and the width of the buffer bucket 300 needs to be smaller than the width of the conveying display belt 200, so the two side walls of the buffer bucket 300 are provided with chutes suitable for the lifting and lowering of the bag-lifting frame 421. Preferably, vertical ears are set at both ends of the bag-lifting frame 421, which are suitable for keeping the upper section of the capping chute when lifting and lowering.

[0073] In practice, the garbage bag may contain certain liquids, such as vegetable juice and tea. In some embodiments, the conveyor display belt 200 is also suitable for filtrate, and a liquid collecting tray is provided below the buffer bucket 300, which is suitable for receiving the filtrate dripped from the upper section of the conveyor display belt 200. The conveyor belt of the conveyor display belt 200 can be a woven belt, a mesh belt (a mesh belt with weft and warp formed in one piece), such as a nylon woven belt, a cloth belt, or a hemp belt, preferably made of a wear-resistant and cut-resistant material. In the bag breaking step, when the top bag frame 421 starts to rise, the conveyor display belt 200 stops running, the garbage bag is initially torn by the second bag breaking hook 321, and the filtrate begins to be discharged. In the bag breaking step, the top bag frame 421 performs multiple top bag breaking operations to fully discharge the filtrate. The downward pressure of the top bag frame 421 is suitable for filtering the liquid of the garbage, and the vibration of the garbage is suitable for accelerating the discharge of the filtrate.

[0074] As described above, in the buffer 300, there may be garbage bags stacked on top of loose garbage, or multiple garbage bags stacked. Preferably, the middle of the four inner walls of the buffer 300 are provided with a third bag breaking row, the third bag breaking row includes a plurality of third bag breaking hooks arranged horizontally, the third bag breaking hooks are inclined and protrude downward, and the upper ends of the four inner walls of the buffer 300 are provided with a first bag breaking row. In the bag breaking step, the bag lifting frame 421 performs multiple bag lifting and breaking operations, so that the garbage bags in the buffer 300 are broken by the second bag breaking hook 321, the third bag breaking hook and / or the first bag breaking hook 311. The bag-lifting frame 421 repeatedly performs multiple lifting operations, and the first bag-breaking hook 311, the second bag-breaking hook 321, and the third bag-breaking hook are all inclined hooks, so when the bag-lifting frame 421 falls back, the intact garbage bag or the garbage bag that is not well broken has a larger impulse to roll down / slide along the bag-breaking hook than the garbage, and the garbage bag has a larger impulse to roll down along the material pile than the garbage, so that the garbage bag falls back to below the hook tip of the bag-breaking hook, so that the garbage bag can be quickly pulled and torn. In the bag-breaking step of the present invention, it is fully.

[0075] On the other hand, there may be garbage bags stacked on top of loose garbage in the buffer 300, or multiple garbage bags stacked, and some garbage bags may not be broken. In the garbage spreading step, the top bag rack 421 is repeatedly raised and lowered, and the garbage bags and garbage bags are supported by the top bag rack 421 and the loose garbage, so that the loose garbage sinks to the bottom of the buffer 300 before the garbage bags, and the loose garbage sinks to the bottom of the buffer 300 before the garbage bags, solving the technical problem that the unbroken garbage bags may be interfered by the loose garbage when they are withdrawn for bag breaking. In the garbage identification step, when the camera identifies the garbage bag, the transmission display belt 200 operates in the reverse direction, so that the garbage bag is broken by the second bag breaking hook 321.

[0076] As described above, when there is no garbage in the buffer 300, the cover 130 can be opened after the timer t0. Combined with the camera 500 having a certain visual range, it can be seen that if there are unbroken garbage bags in the garbage being transferred, the camera 500 can detect it in time within the timer t0, and then temporarily lock the cover 130 to avoid unbroken garbage bags when new garbage is put in.

[0077] The bag lifting frame 421 can be lifted by a pneumatic cylinder, a hydraulic cylinder or an electric cylinder. The bag lifting frame 421 can be lowered by its own weight and / or the pressure of garbage without inflating the cylinder body.

[0078] Reference Figure 3 , Figure 5 Preferably, the first bag breaking row 310 includes a first base 312 connected to the buffer bucket 300, and a plurality of first blades 313 spaced apart on the first base 312. One side of the first blade 313 is integrally formed with the first base 312, and the first bag breaking hook 311 corresponds one-to-one to the other side of the first blade 313. The lower end of the first blade 313 is a blade. When the garbage bag that has been pierced by the first bag breaking hook 311 moves upward, it is quickly broken and / or cut apart; the blade and the bag breaking hook reinforce each other, and the blade and the bag breaking hook are not easy to bend or crack. Figure 3 , Figure 5 The second bag-breaking row 320 includes a second base 322 connected to the buffer bucket 300, and a plurality of second blades 323 arranged at intervals on the second base 322. One side of the second blade 323 is integrally formed with the second base 322, and the second bag-breaking hook 321 corresponds one-to-one to the other side of the second blade 323, and the lower end of the second blade 323 is a blade. The transmission display belt 200 drives the garbage bag in reverse, and the garbage bag that has been pierced by the second bag-breaking hook 321 is fully and quickly hooked and / or cut apart when moving upward. On the other hand, the second blade 323 greatly reduces the armpit capacity of the second bag-breaking hook 321. When the second bag-breaking hook 321 pierces the garbage bag, the armpit of the second bag-breaking hook 321 can only accommodate a small amount of garbage, so the garbage in the bag can only be squeezed above the second bag-breaking hook 321. On the other hand, the third bag-breaking row can also be provided with a third blade and a third base with similar structures.

[0079] It is understandable that during the processing and forming of the first bag breaking row 310 and the second bag breaking row 320, the base can be formed integrally with the buffer bucket 300 together with the blades and the bag breaking hooks, such as being simultaneously cast and welded together; the base can also be detachably connected to the buffer bucket 300.

[0080] Reference Figure 3 , Figure 5 Furthermore, the hook tip of the first bag breaking hook 311 is lower than the lower end of the first blade 313, and the hook tip of the second bag breaking hook 321 is lower than the lower end of the second blade 323, so the garbage bag is suitable to be pierced by the bag breaking hook first, so as to obtain a certain degree of stability exerted by the bag breaking hook, avoid the garbage bag from swinging left and right to a large extent, and make the garbage bag more stably collide with the blade when moving up; the blade is suitable for cutting the garbage bag, or is suitable for the pulling edge of the bag breaking hook, so that the garbage bag moving up is torn and scattered by the hook.

[0081] In addition, refer to Figure 3 , Figure 5 The hook tip of the second bag-breaking hook 321 protrudes out of the second blade 323, the second bag-breaking hooks 321 are arranged at intervals, and the second blade 323 and the second bag-breaking hooks 321 are spliced ​​into a bag-breaking device in a one-to-one correspondence. Therefore, when the garbage bag carrying its garbage hits multiple second bag-breaking hooks 321, it is convenient for the irregular strips of garbage in the garbage bag to be adjusted to a certain regularity, that is, to be stacked regularly under the armpits of the second bag-breaking hooks 321, and / or to be stacked regularly and moved up along the second bag-breaking hooks 321. It can be understood that the "certain regularity" refers to the proportion of the garbage in the garbage bag that is closer to the second bag-breaking hooks 321, and this part of the garbage is combed and regularized by multiple bag-breaking devices.

[0082] Reference Figure 3 , Figure 5 Furthermore, the lower ends of the first blade 313 and the second blade 323 are serrated blades, so that crispy and tender kitchen waste such as fruits and vegetables can be easily cut, and tough waste such as plastic can be easily cut under the combined action of cutting and pulling.

[0083] In some embodiments of the present invention, the chassis 100 is integrally formed with a storage well (vertical well or inclined well), and the buffer bucket 300 belongs to the storage well, that is, part or all of the storage well is used as the buffer bucket 300 .

[0084] In some embodiments, the chassis 100 is provided with an insertion port, and the buffer bucket 300 is adapted to be sunk into the insertion port one by one. It is understandable that the insertion port can be a shallow opening opened in the sheet metal part, or a sink hole / well. Further, the peripheral wall of the insertion port is provided with a support platform, referring to Figures 2 to 5The buffer bucket 300 is provided with a plurality of lugs 340, and the lugs 340 are suitable for hanging on the corresponding supporting platform. The intelligent garbage classification and recycling method includes a disassembly and cleaning step, and the buffer bucket 300 is cleaned after being disassembled from the chassis 100. The buffer bucket 300 is detachably connected to the chassis 100, so further, the material level sensor 330 can be detachably connected to the buffer bucket 300.

[0085] In practice, the back area of ​​the taller garbage is the area that the soft material picker 410 cannot sweep, and multiple smaller garbage may still be stacked in this area. On the other hand, it is difficult for the soft material picker 410 to solve the stacking of three or more wet garbage, such as three or more kitchen waste. In addition, the spreading time of the soft material picker 410 is relatively short, and the soft material picker 410 can only spread out garbage piles with fewer layers in a short time. On the other hand, it is difficult to fully tear apart the garbage bag by only combining the transmission display belt 200 with the second broken bag row 320, and it is difficult to spread out the garbage that is not fully scattered by sweeping twice with the soft material picker 410. These multiple technical problems have not been solved, refer to Figures 2 to 4 In some embodiments, the upper section of the conveying display belt 200 is supported by the corresponding vibration table 430, and the soft material picking member 410 and its corresponding buffer 300 are both arranged above the corresponding vibration table 430, and the vibration table 430 supports the garbage through the corresponding conveying display belt 200. In the present invention, the garbage scattered in the buffer 300 begins to vibrate and spread, and then is vibrated and swept during the transmission to further spread it fully. The vibration table 430 can be an air vibrator, an electric vibrator, etc., and can also be connected to a gas shock hammer.

[0086] In the garbage spreading step, the garbage scattered in the buffer bucket 300 is spread out by vibration, and the garbage transferred from the buffer bucket 300 to the bottom of the camera 500 is spread out by vibration and sweeping.

[0087] In the bag breaking step, the bag lifting rack 421 performs one or more bag lifting and breaking operations, and the lower end of the broken garbage bag is shaken and / or vibrated to release the garbage. It is understandable that when the garbage is separated from the broken garbage bag, the lower end of the broken garbage bag is shaken to a certain extent, which aggravates the scattering of the garbage.

[0088] In the garbage spreading step, the top bag frame 421 is repeatedly raised and lowered, the transmission display belt 200 vibrates, and the top bag frame 421 descends to press the garbage in the buffer bucket 300, so that the garbage is spread more quickly.

[0089] In the garbage spreading step, the conveying display belt 200 operates forward, and the repeated lifting and lowering of the top bag rack 421 causes the broken and emptied garbage bags to slide to the upper end of the second bag breaking hook 321 and the conveying display belt 200 in sequence.

[0090] On the other hand, it is understandable that the bag top frame 421 cooperates with the second bag breaking row 320 to break the bag, and the bag top frame 421 is not located directly below the second bag breaking hook 321. In the present invention, the garbage bag is generally of a conventional size of φ250mm, the second bag breaking hook 321 is suitable for hooking the side end of the garbage bag, and the bag top frame 421 is suitable for pushing the middle of the garbage bag; therefore, the vertical projection spacing between the bag top frame 421 and the second bag breaking hook 321 is greater than 0 and less than or equal to 120mm, such as 20 / 30 / 40 / 50 / 60mm spacing.

[0091] In practice, the height of daily / household trash cans is 250mm, and the actual height of the trash bag is ≤250mm. It is preferably designed that in the bag breaking step, the upper bag breaking action height of the top bag rack 421 is ≥100mm. The effect is poor when only one second bag breaking hook 321 cooperates with a top bag of ≥100mm. Furthermore, the upper bag breaking action height of the top bag rack 421 is ≥150mm. In the garbage spreading step, one end of the garbage bag is hooked by the second bag breaking hook 321 at the beginning, and the middle part is hung on the top bag rack 421, so the top bag rack 421 is repeatedly raised and lowered to fully shake out the garbage in the broken garbage bag; the top bag rack 421 continues to be repeatedly raised and lowered, and the garbage bag gradually breaks away from the top bag rack 421 and falls to the upper side of the second bag breaking hook 321, and then slides to the transmission display belt 200, and is dragged away by the transmission display belt 200, so as to be displayed and sorted as a piece of garbage.

[0092] In reality, non-kitchen waste may be mixed with metal waste, and even kitchen waste may be mixed with metal waste, such as nails, broken blades, etc. Figures 2 to 4In some embodiments, a tail pulley connected to the tail end of the conveying display belt 200 is provided with a magnetic block, a non-transmitting surface of the lower section of the conveying display belt 200 is abutted against a magnetic suction table 610, one end of the magnetic suction table 610 extends to the tail pulley, and a metal recovery box 770 is provided below the conveying display belt 200, and the metal recovery box 770 is suitable for receiving metal garbage that has moved away from the magnetic suction table 610. The magnetic block and the magnetic suction table 610 can be permanent magnets or electromagnets that are normally powered, and the metal recovery box 770 deviates from the bottom of the magnetic suction table 610, has been transferred to the lower side of the conveying display belt 200, and the metal garbage that has deviated from the magnetic suction table 610 by a certain distance is subject to insufficient magnetic attraction, and the metal garbage falls into the metal recovery box 770 based on gravity. In the sorting and delivery step, after the paper, plastic, and glass are sorted, and the main garbage corresponding to the conveying display belt 200 is dumped, the metal garbage is transferred to the metal recovery box 770 by magnetic attraction. In the present invention, metal waste is also sorted, and the sorting labor of the sorting robot is saved. It can be understood that daily life metal waste is not the iron blocks and iron bars used in machine tools, vehicles and ships. Daily metal waste is sheet metal parts, and the largest scale is household appliance sheet metal parts, that is, daily metal waste ≤ 0.5kg; among them, the metal waste that can be put into daily / civilian trash cans is ≤ 0.3kg, that is, non-large metal waste is ≤ 0.3kg, and general permanent magnets and electromagnets can completely overcome the gravity of the metal waste.

[0093] In practice, the garbage bag contains vegetable juice, sauce, tea, etc., which results in the conveying surface of the conveying display belt 200 still having dirt, slag, etc. after the garbage sorting is completed. In some embodiments, a cleaning mechanism is arranged below the conveying display belt 200, and the cleaning mechanism includes a dirt collection tank, a roller brush arranged at the slot of the dirt collection tank, and a first nozzle. The intelligent garbage classification and recycling method includes a cleaning step, and the first nozzle is suitable for spraying cleaning liquid toward the conveying display belt 200 and / or the roller brush, and the roller brush is suitable for sweeping the conveying surface of the lower section of the conveying display belt 200. Preferably, a second nozzle is also included, and the intelligent garbage classification and recycling method includes a disinfection step, and the second nozzle is suitable for spraying disinfectant toward the cleaned conveying display belt 200.

[0094] In some embodiments, a photovoltaic panel is also included, which is suitable for providing working power to the central processor, the transmission display belt 200, the camera 500, the sorting robot, etc.

[0095] In some embodiments, fire detection components are provided above the buffer 300, the transport display belt 200, and the trash bin 700. The fire detection components include infrared temperature sensors, smoke gas sensors (and / or air quality sensors). The infrared temperature sensors and smoke gas sensors are electrically connected to a central processing unit. The central processing unit is suitable for controlling the transport display belt 200, the camera 500, and the sorting robot to sleep according to the infrared temperature sensor detecting high temperature and the smoke gas sensor detecting smoke. The central processing unit sends an alarm to the cloud server. For example, the infrared temperature sensor triggers a temperature of 55-70 degrees Celsius, and the smoke gas sensor triggers a threshold of 5% OBS / M to 15% OBS / M. Furthermore, an alarm is provided on the outer wall of the chassis 100, such as a fire buzzer and a fire warning light, and the alarm is electrically connected to the central processing unit.

[0096] In some embodiments, a deodorizing mechanism is also included, and the deodorizing mechanism includes an electronic emitter. During the disinfection step, the electronic emitter is suitable for emitting electronic pulses toward the inner cavity of the buffer bucket 300, the transmission display belt 200, the sorting robot, and the inner cavity of the trash bin 700; when the electrons collide with bacteria and mold spores, the chemical energy transmitted is the same or similar to the bond energy of the chemical bonds, breaking the chemical bonds of the mold bacteria, preventing the bacteria and mold from multiplying, thereby achieving a deodorizing effect. In some embodiments, ultraviolet germicidal lamps are arranged on the upper and lower sides of the transmission display belt 200, the inner side of the buffer bucket 300, and the top of the trash bin 700. The ultraviolet germicidal lamp is always on, or is controlled to light up by the central processing unit. When the transmission display belt 200 is started, the ultraviolet germicidal lamp is turned on, and after the transmission display belt 200 stops for a predetermined time, the ultraviolet germicidal lamp is turned off.

[0097] The above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Any modification or equivalent substitution that does not depart from the spirit and scope of the present invention shall be included in the scope of the technical solution of the present invention.
