Description

Technical Field

[0001] This invention relates to the field of trash can technology, specifically a sorting trash can and its sorting control method. Background Technology

[0002] Waste is mainly divided into four categories: kitchen waste, other waste, recyclable waste, and hazardous waste. Specifically, it includes the following: kitchen waste includes vegetable leaves, chopped white radishes, carrots, small potato chunks, etc.; other waste includes broken porcelain pieces, pebbles, broken flower pots, dishes, cigarette butts, etc.; recyclable waste includes aluminum cans, beverage bottles, waste paper, etc.; and hazardous waste includes batteries, medical waste, etc.

[0003] Traditional recycling bins can only guarantee the identification and disposal of single pieces of waste. When continuously disposing of waste, the identification and disposal process can be inaccurate, making it difficult to ensure accurate identification and disposal speed. Therefore, they are not suitable for market promotion and lack practicality.

[0004] Moreover, in traditional recycling bins, each waste storage unit is often designed as an open structure to ensure that the disposal components can effectively put the waste in. This makes it difficult to seal the opening, which leads to the spread of garbage odors and affects the surrounding environment.

[0005] In actual use, the amount of kitchen waste and recyclable waste disposed of is often larger than that of other waste and hazardous waste. This results in the storage units for kitchen waste and recyclable waste being full while the storage units for other waste and hazardous waste are still only partially loaded. This increases the frequency of waste transfer and cleaning, which is not conducive to its application in society. Summary of the Invention

[0006] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide a sorting trash can and its control method, which can accurately and quickly sort various types of trash that are continuously put in, and put the trash of a certain type into the corresponding trash storage bin. This can effectively increase the trash loading capacity of the sorting trash can and effectively prevent the leakage of trash odor, thereby improving the environmental quality around the trash can.

[0007] The technical solution adopted by the present invention to achieve the above objectives is as follows: a classified garbage bin, comprising an installation frame and a sorting and conveying component, a garbage sorting component, a garbage storage bin, a crushing component, and a compression component assembled in the installation frame.

Four sets of garbage transfer ports are opened on the bottom side wall of the protective cover, and the garbage transfer ports are equipped with matching cabinet doors.

[0021] In some implementations, to ensure that the crushing component can crush the waste in the food waste bin, so that the food waste bin can hold more food waste, and to avoid movement interference between the food waste bin and the crushing component when it is taken out or put in, the following technical solutions are provided.

The pressure seat is fixedly connected to the bottom end of the guide shaft and arranged below the corresponding sealing top cover.

[0025] A method for controlling the classification of waste bins, applied to the aforementioned type of waste bin, comprises the following steps:

[0026] S1, the waste is put into the sorting and conveying component, which then arranges the waste evenly and identifies the waste type;

[0027] S2, control the operation of the waste sorting component according to the identified waste type. The servo motor controls the tray to move towards the corresponding waste storage bin. When the identified waste falls into the tray, the electric telescopic cylinder controls the tray to flip downwards, and at the same time controls the corresponding sealing slide to open, so that the waste in the tray is poured into the corresponding waste storage bin.

[0028] S3, determine whether each garbage storage bin is full and display it on the electronic display screen, and stop garbage disposal when the garbage storage bin is full;

[0029] S4: After the waste is sorted and stored in the corresponding waste storage bin, the crushing component is controlled to crush the kitchen waste, and the compression component is controlled to compress the recyclable waste.

[0030] The beneficial effects of the present invention are as follows: the sorting and conveying component can evenly distribute various types of waste that are put on it, and after waste identification at the end, the waste is input to the waste sorting component. The waste sorting component can put the waste into the corresponding waste storage bin according to the waste identification result. The coordinated operation of the sorting and conveying component and the waste sorting component can accurately and quickly classify various types of waste that are continuously put on, and put the waste of the determined type into the corresponding waste storage bin.

[0031] In practical use, the amount of kitchen waste and recyclable waste put in is far greater than that of hazardous waste and other waste. The crushing component can crush kitchen waste to increase the loading capacity of the kitchen waste bin, and the compression component can compress recyclable waste to increase the loading capacity of the recyclable waste, which can effectively increase the loading capacity of the classified waste bins.

[0032] When the waste sorting component is in operation to classify and dispose of waste, the corresponding sealing top cover can be opened synchronously through the transmission component. After the disposal is completed and the waste sorting component is reset, the sealing top cover can be automatically reset and closed, which can effectively prevent the leakage of waste odor and improve the environmental quality around the waste bin.

Detailed Implementation

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] Please see Figure 1-15 The technical solutions, installation and arrangement relationships, and operating principles of the components in this invention will be explained in conjunction with the following embodiments. Example

[0051] A recycling bin includes a mounting frame 1 and a sorting and conveying component, a waste sorting component, a waste storage bin 4, a crushing component, and a compression component, all mounted on the mounting frame 1. The sorting and conveying component is mounted on the top of the mounting frame 1 and is used to receive the waste and evenly convey it to the waste sorting component. The waste sorting component is mounted on the downstream end of the sorting and conveying component and is used to put different types of waste into the corresponding waste storage bins 4. The waste storage bins 4 are mounted below the waste sorting component and include a food waste bin 401, a other waste bin 402, a recyclable waste bin 403, and a hazardous waste bin 404. Each set of waste storage bins 4 is used to store the corresponding type of waste. The crushing component is mounted in the food waste bin 401 and is used to crush the food waste. The compression component is mounted in the recyclable waste bin 403 and is used to compress the recyclable waste.

[0052] The sorting and conveying component can evenly distribute various types of waste that are put on it. After waste identification at the end, the waste is input into the waste sorting component. The waste sorting component can put the waste into the corresponding waste storage bin 4 according to the waste identification result. The coordinated operation of the sorting and conveying component and the waste sorting component can accurately and quickly classify various types of waste that are continuously put on it, and put the waste of the identified type into the corresponding waste storage bin 4.

[0053] In practical use, the amount of kitchen waste and recyclable waste put in is much greater than that of hazardous waste and other waste. The crushing component can crush the kitchen waste to increase the loading capacity of the kitchen waste bin 401, and the compression component can compress the recyclable waste to increase the loading capacity of the recyclable waste, which can effectively increase the waste loading capacity of the classified waste bins.

[0054] When the waste sorting component is operating to sort and dispose of waste, the corresponding sealing top cover 14 can be opened synchronously through the transmission component 143. After disposal is completed and the waste sorting component is reset, the sealing top cover 14 can be automatically reset and closed, which can effectively prevent the leakage of waste odor and improve the environmental quality around the waste bin. Example

[0055] To ensure that the separate transmission component, waste sorting component, and waste storage bin 4 can be stably installed in the mounting frame 1, and to effectively protect the components assembled in the mounting frame 1, and to stably input the waste to be disposed of into the branch transmission component, the following related technical solutions are provided.

[0056] The mounting frame 1 is externally covered by a protective cover 11. A flow guide channel is fixed on the top inner side of the protective cover 11. A disposal port 112 connected to the flow guide channel is opened on the top side wall of the protective cover 11. A mounting top plate 12 and a mounting bottom plate 13 are fixed to the top and bottom of the mounting frame 1, respectively. The separate transmission component is installed below the mounting top plate 12. A garbage outlet 121 connected to the flow guide channel is opened on the mounting top plate 12. The garbage outlet 121 is arranged at the upstream end of the separate transmission component. The garbage storage box 4 is installed above the mounting bottom plate 13.

[0057] The protective cover 11 effectively protects the mounting frame 1, ensuring that the components assembled therein are stably installed in specific positions. The protective cover 11 effectively protects the components, ensuring the stable operation of the components on the mounting frame 1.

[0058] After the garbage is put into the disposal port 112, it falls along the guide channel and garbage outlet 121 into the upstream end of the sorting and conveying component. The sorting and conveying component then transports the received garbage into the garbage sorting component. During this process, the garbage received at the upstream end of the sorting and conveying component can be distributed as evenly as possible to ensure that the garbage sorting component can input specific types of garbage into the corresponding garbage storage bin 4.

[0059] An inclined electronic display screen 71 is fixedly installed on the top front side of the protective cover 11. A rain shield 113 is also fixedly connected to the top of the protective cover 11 and arranged above the electronic display screen 71 to effectively protect the electronic display screen 71. As a specific implementation, the electronic display screen 71 can be a 4.3-inch serial port screen of the Taojingchi X5 series. Through the host computer software USART HMI, it can play garbage classification promotional videos, display garbage classification results in real time, and provide garbage full alarm reminders. Example

[0060] To ensure that the sorting and transfer component can be stably installed in the mounting rack 1 and realize the sorting and transfer function of the received waste, so that the waste is put into the waste sorting component as evenly as possible, the following technical solution is provided.

[0061] The separate transmission assembly includes an upper chain plate 21, a lower chain plate 22, an upper drive shaft 23, a lower drive shaft 24, a drive sprocket 25, a first motor 26, and a second motor 27. The upper drive shaft 23 includes two sets arranged side-by-side on the same horizontal plane, and a drive sprocket 25 is fixedly connected to the upper drive shaft 23. The upper chain plate 21 is arranged around the upper drive shaft 23 and meshes with the corresponding drive sprocket 25. The upstream end of the upper chain plate 21 is arranged below the waste outlet 121. One set of upper chain plates... The drive shaft 23 is powered by the first motor 26; the lower drive shaft 24 includes two sets arranged side by side on the same horizontal plane, and the lower drive shaft 24 is arranged below the upper drive shaft 23. A drive sprocket 25 is fixedly connected to the lower drive shaft 24. The lower chain plate 22 is arranged around the lower drive shaft 24 and meshes with the corresponding drive sprocket 25. The upstream end of the lower chain plate 22 is arranged at the downstream end of the upper chain plate 21. One set of lower drive shafts 24 is powered by the second motor 27.

[0062] The two sets of upper drive shafts 23 and the drive sprockets 25 mounted on them can be matched and combined with the upper chain plate 21. When the first motor 26 drives the corresponding upper drive shaft 23 to rotate, it can drive the upper chain plate 21 to run stably, thereby transporting the garbage bin upstream of the upper chain plate 21 downstream, and finally falling into the upper part of the lower chain plate 22.

[0063] Similarly, the two sets of lower drive shafts 24 and the drive sprockets 25 mounted on them can be matched and combined with the lower chain plate 22. When the second motor 27 drives the corresponding lower drive shaft 24 to rotate, the garbage can be transported from the upstream end of the lower chain plate 22 to the downstream end, and finally fed into the garbage sorting component for further processing.

[0064] The upper chain plate 21 and the lower chain plate 22 are arranged in a zigzag pattern. By controlling the output speed of the first motor 26 and the second motor 27, the running speed of the upper chain plate 21 and the lower chain plate 22 can be adjusted in real time, so that the garbage conveyed downstream of the upper chain plate 21 is evenly distributed on the lower chain plate 22, and then evenly conveyed to the garbage sorting component by the lower chain plate 22 to ensure the stable operation of the garbage sorting component.

[0065] Both the first motor 26 and the second motor 27 are geared motors, and a drive gear 28 is fixedly connected to the output shaft of both the first motor 26 and the second motor 27. A reduction gear 29 that meshes with the drive gear 28 is fixedly connected to the corresponding upper transmission shaft 23 and lower transmission shaft 24. The number of teeth of the reduction gear 29 is greater than that of the drive gear 28, which can further reduce the speed transmitted from the first motor 26 and the second motor 27, so that the upper chain plate 21 and the lower chain plate 22 can operate stably at a lower running speed.

[0066] When the upper chain plate 21 and lower chain plate 22 in the sorting and conveying assembly are used for sorting and conveying waste, in order to ensure that the waste can be stably conveyed on them to avoid the risk of falling, and at the same time to ensure that the upper drive shaft 23, lower drive shaft 24, upper chain plate 21, lower sprocket, first motor 26 and second motor 27 are stably installed in the mounting frame 1, the following technical solution is provided.

[0067] Two sets of parallel vertical baffles 122 are fixedly connected to the lower surface of the mounting plate 12. The upper drive shaft 23 and the lower drive shaft 24 are rotatably mounted on the vertical baffles 122. The upper chain plate 21 and the lower chain plate 22 are arranged between the two sets of vertical baffles 122. The upper support plate 123 and the lower support plate 124 are also fixedly installed on the two sets of vertical baffles 122. The upper support plate 123 is arranged below the upper chain plate 21. The first motor 26 is fixedly installed on the upper support plate 123. The lower support plate 124 is arranged below the lower chain plate 22. The second motor 27 is fixedly installed on the lower support plate 124. Side baffles 125 are also fixedly connected to both ends of the two sets of vertical baffles 122.

[0068] The relatively sealed space formed by the combination of the top plate 12, vertical baffle 122, and side baffle 125 allows the waste transported on the separate conveyor assembly to be transported within this space, preventing the waste from detaching from the upper chain plate 21 or the lower chain plate 22 and improving the stability of the waste transport by the separate conveyor assembly. The upper support plate 123 can stably support the upper chain plate 21 and ensure the stable installation of the first motor 26 so that the first motor 26 can drive the upper chain plate 21 to operate stably. Similarly, the lower support plate 124 can stably support the lower chain plate 22 and ensure the stable installation of the second motor 27 so that the second motor 27 can drive the lower chain plate 22 to operate stably.

[0069] A high-definition camera and a light source are fixed to the lower surface of the upper support plate 123 and arranged facing the lower chain plate 22 to take pictures of the garbage transported on the lower chain plate 22. The light source can supplement the light to ensure that the high-definition camera can capture clear and complete images.

[0070] The captured images of waste are transmitted to a waste identification system for type recognition. As one implementation method, the waste identification system is a commonly used solution. This involves training an image recognition model using TensorFlow on a computer, converting the model to TFLite format, porting it to a small terminal device such as a Raspberry Pi, and re-importing the model for image recognition application. The image data captured by the high-definition camera is processed and imported into the image recognition model for analysis to determine the type of waste. Specifically, it identifies whether the waste belongs to kitchen waste, other waste, recyclable waste, or hazardous waste, ensuring that the waste sorting component can place the corresponding type of waste into the appropriate waste storage bin 4. Example

[0071] To ensure that the waste sorting component can stably receive the waste transmitted from the sorting and conveying component, identify the type of waste, and stably transport the waste to the corresponding waste storage bin 4, the following technical solution is provided.

[0072] The waste sorting assembly includes a servo motor 31, a mounting bracket 32, a tray 33, a drive bracket 34, and an electric telescopic cylinder 35. The servo motor 31 is fixedly mounted on the mounting frame 1. The mounting bracket 32 ​​is mounted on the servo motor 31 and maintains a power connection with the servo motor 31. The tray 33 is located downstream of the lower chain plate 22, and a horizontally arranged mounting shaft 331 is fixedly connected to the bottom of the tray 33. The mounting shaft 331 is rotatably mounted on the mounting bracket 32. The drive bracket 34 is slidably mounted on the mounting bracket 32 ​​and moves up and down in the vertical direction. A support slide 341 is hinged to the top of the drive bracket 34 and is slidably mounted on the bottom of the tray 33. The electric telescopic cylinder 35 is fixedly mounted on the mounting bracket 32 ​​and is poweredly connected to the drive bracket 34.

[0073] The bottom of the servo motor 31 is fixedly connected to a connecting bracket plate 311, which is fixedly installed on the mounting frame 1 to ensure that the servo motor 31 is stably installed in the mounting frame 1. When the servo motor 31 is running, it can drive the mounting bracket 32 ​​mounted on it and the various parts mounted on the mounting bracket 32 ​​to rotate stably around the longitudinally arranged axis, so that the guide port 332 on the tray 33 can face the specific type of garbage storage box 4. When the electric telescopic cylinder 35 drives the drive bracket 34 to move up and down, it drives the drive tray 33 to rotate around the mounting axis 331 through the support slide 341, so that the guide port 332 on the tray 33 flips down and aligns with the corresponding garbage storage box 4. The garbage carried on the tray 33 can fall from the guide port 332 into the corresponding garbage storage box 4, so that the identified garbage is loaded into the corresponding garbage box.

[0074] The support slide 341 can slide stably on the tray 33. The tray 33 is equipped with a guide rail that is perpendicular to the mounting shaft 331. The support slide 341 is slidably mounted on the guide rail.

[0075] After identifying and classifying the waste, the waste identification system transmits the processing results to the electronic control module, which is powered by a 51 microcontroller. When powered on, the 51 microcontroller controls the rotation, acceleration, and deceleration of the first motor 26 and the second motor 27 via the L298N dual H-bridge DC motor drive module, achieving precise control of the separate transmission components. The Raspberry Pi, based on the image recognition results, calls the servo motor 31 to rotate in advance. The Raspberry Pi connects to the PCA9685 via the I2C protocol to control the MG996R servo motor 31 to rotate at various angles and control the operation of the electric telescopic cylinder 35, causing the identified waste to fall into the corresponding waste storage bin 4, thus achieving intelligent waste sorting and processing.

[0076] To ensure that the waste placed on the tray 33 falls stably into the corresponding waste storage bin 4, and to prevent odors from spreading out of the waste storage bin 4 after the waste is disposed of, the following technical solution is provided.

[0077] The mounting frame 1 is also fixedly installed with four sets of sealed top covers 14 arranged above the garbage storage bin 4, and the four sets of sealed top covers 14 are respectively matched with the top openings of the kitchen waste bin 401, other waste bin 402, recyclable waste bin 403, and hazardous waste bin 404; each set of sealed top covers 14 has a garbage inlet 141, and a sealing slide plate 142 is slidably installed at the garbage inlet 141, and the drive bracket 34 interacts with the sealing slide plate 142 through the transmission component 143.

[0078] The transmission assembly 143 includes a lifting sleeve 1431, a lifting seat 1432, a support spring 1433, and a connecting rod 1434. The lifting sleeve 1431 is fixedly installed on the sealing top cover 14. The lifting seat 1432 is slidably installed in the lifting sleeve 1431. The support spring 1433 is arranged in the lifting sleeve 1431 and abuts against the lifting seat 1432. The two ends of the connecting rod 1434 are respectively hinged to the lifting seat 1432 and the sealing slide plate 142.

[0079] The sealed top cover 14 and the sealed sliding plate 142 mounted thereon ensure that the matching waste storage bin 4 is sealed when no waste is being put in, preventing the odor from spreading and affecting the surrounding environment. When the waste sorting component empties the waste into the waste storage bin 4 of the corresponding type after identification, the servo motor 31 will drive the components mounted on it to rotate as a whole to the corresponding waste storage bin 4. At this time, the bottom end of the drive bracket 34 is exactly above the corresponding lifting sleeve 1431. When the electric telescopic cylinder 35 drives the drive bracket 34 to descend, it will drive the waste storage bin 4 corresponding to the tray 33 to flip. At the same time, the drive bracket 34 pushes the lifting seat 1432 downward in the lifting sleeve 1431, and pushes the sealing slide plate 142 into the open state through the connecting rod 1434, so that the garbage on the tray 33 can be poured from the garbage inlet 141 into the corresponding garbage storage box 4. When the electric telescopic cylinder 35 drives the drive bracket 34 upward, it can reset the tray 33 to the horizontal state. At the same time, the drive bracket 34 cancels the downward pressure on the lifting seat 1432, and under the action of the support spring 1433, it drives the lifting seat 1432 to rise, and drives the sealing slide plate 142 to reseal the garbage inlet 141.

[0080] When the pallet 33 is tilted down to dump garbage, in order to prevent the garbage that falls first from landing on the not fully opened sealing slide plate 142 and affecting the stability of the garbage dumping process, a guide ramp 144 is also fixedly installed on the sealing top cover 14. The top of the guide ramp 144 is opposite to the tilted pallet 33, and the bottom of the guide ramp 144 is arranged facing the garbage inlet 141. When the pallet 33 is tilted, the garbage will enter the guide ramp 144 and flow down along the guide ramp 144, which can prolong the garbage falling time, thereby ensuring that the sealing slide plate 142 can be fully opened so that the garbage can enter the garbage inlet 141 normally. Example

[0081] To facilitate the removal and transfer of waste stored in each waste storage bin 4 from the protective cover 11, and to ensure that each waste storage bin 4 installed in the mounting frame 1 can be sealed and fit tightly with the corresponding sealing top cover 14, the following technical solution is provided.

[0082] Multiple sets of sliding guide rails 131 are fixedly installed on the mounting base plate 13. Each set of garbage storage boxes 4 has a sliding guide groove 41 that slides with the sliding guide rails 131 at the bottom. Four sets of garbage transfer ports 114 are opened on the bottom side wall of the protective cover 11, and the garbage transfer ports 114 are equipped with matching cabinet doors 115.

[0083] After the cabinet door 115 is opened, the corresponding garbage storage bin 4 can be pulled out from the inside of the protective cover 11 along the sliding guide rail 131 to transfer the garbage inside, or the empty garbage storage bin 4 can be pushed into the protective cover 11 along the corresponding sliding guide rail 131 to reassemble it under the corresponding sealing top cover 14.

[0084] To ensure that the garbage storage bin 4 installed in the protective cover 11 can be sealed and fit with the corresponding sealing top cover 14, four sets of nested brackets 132 are also fixedly connected to the mounting base plate 13. The nested brackets 132 are nested and engaged with the inner side walls of the four sets of garbage storage bins 4 respectively. Supporting pads 1151 are fixedly connected to the inner wall of each cabinet door 115. When the cabinet door 115 is closed, the supporting pads 1151 can tightly abut against the outer side wall of the corresponding garbage storage bin 4 so that the garbage storage bin 4 is in a relatively fixed state, so as to ensure that the garbage storage bin 4 can be sealed and combined with the corresponding sealing top cover 14.

[0085] To facilitate a direct understanding of the garbage disposal status in each garbage storage bin 4 and to prevent garbage from being added when the garbage storage bin 4 is full, an ultrasonic ranging sensor 72 arranged vertically upward is installed on the mounting base plate 13. Based on the characteristics of the ultrasonic ranging sensor 72 and the changes in the electrical signal, it is possible to monitor in real time whether the garbage is full and whether the garbage height has generally reached the preset height. If it has, a full load alarm will be triggered.

[0086] The 51 microcontroller is also connected to the electronic display screen 71, which displays whether each garbage storage bin 4 is full. Example

[0087] To ensure that the crushing component can crush the waste in the food waste bin 401, thereby allowing the food waste bin 401 to hold more food waste, and to prevent movement interference between the food waste bin 401 and the crushing component when it is being removed or loaded, the following technical solution is provided.

[0088] The crushing assembly includes a lifting bracket 51, a first hydraulic cylinder 52, a drive motor 53, and crushing blades 54. The lifting bracket 51 is slidably mounted on one of the sealed top covers 14 and arranged directly above the kitchen waste bin 401. The first hydraulic cylinder 52 is fixedly mounted on the mounting frame 1 and is poweredly connected to the lifting bracket 51. A vertically arranged connecting shaft 55 is rotatably mounted on the lifting bracket 51, and multiple sets of crushing blades 54 are fixedly connected to the bottom of the connecting shaft 55. The drive motor 53 is fixedly mounted on the top of the lifting bracket 51 and is poweredly connected to the connecting shaft 55.

[0089] When the kitchen waste in the kitchen waste bin 401 is crushed, the first hydraulic cylinder 52 drives the lifting bracket 51 and the various components mounted on the lifting bracket 51 to descend synchronously, so that the crushing blade 54 extends into the kitchen waste bin 401. When the drive motor 53 is working, it can drive the crushing blade 54 to rotate at high speed to crush the fruits, vegetables and other items in it.

[0090] When it is necessary to remove or put back the food waste bin 401, the first hydraulic cylinder 52 is controlled to drive the lifting bracket 51, the connecting shaft 55, and the crushing blade 54 to the top of the stroke. At this time, the connecting shaft 55, the crushing blade 54, etc. are in the corresponding sealed top cover 14, and there is no movement interference with the food waste bin 401, so the food waste bin 401 can be picked up and put back normally.

[0091] To ensure that the compression component can compress the recyclable waste in the recyclable waste bin 403 so that the recyclable waste bin 403 can hold more recyclable waste, and to avoid motion interference between the recyclable waste bin 403 and the compression component when it is taken out or put in, the following technical solution is provided.

[0092] The compression assembly includes a pressure seat 61, a second hydraulic cylinder 62, and a guide shaft 63. The guide shaft 63 is slidably mounted on one of the sealed top covers 14 and is positioned directly above the recyclable waste bin 403. The second hydraulic cylinder 62 is fixedly mounted on the mounting frame 1 and is poweredly connected to the guide shaft 63. The pressure seat 61 is fixedly connected to the bottom end of the guide shaft 63 and is positioned below the corresponding sealed top cover 14.

[0093] When compressing the recyclable waste in the recyclable waste bin 403, the second hydraulic cylinder 62 drives the guide shaft 63 and the pressure seat 61 to descend, so that the pressure seat 61 applies downward pressure to the waste in the recyclable waste bin 403 to compact and compress waste such as aluminum cans and plastic bottles.

[0094] When it is necessary to remove or put back recyclable waste, the second hydraulic cylinder 62 is controlled to drive the guide shaft 63 and the pressure seat 61 to the top of the stroke. At this time, the pressure seat 61 is in the corresponding sealed top cover 14, and there is no movement interference with the recyclable waste bin 403, which can ensure its normal removal and placement.

[0095] The 51 microcontroller controls the first hydraulic cylinder 52, the second hydraulic cylinder 62, and the drive motor 53 through a relay module to achieve the working effect of the crushing component and the compression component. Example

[0096] A method for controlling the classification of waste bins, applied to a type of waste bin described in Examples 1-6, comprises the following steps:

[0097] S1, the waste is put into the sorting and conveying component, which then arranges the waste evenly and identifies the waste type;

[0098] S2, the operation of the waste sorting component is controlled according to the identified waste type. The servo motor 31 controls the tray 33 to move towards the corresponding waste storage box 4. When the identified waste falls into the tray 33, the electric telescopic cylinder 35 controls the tray 33 to flip downwards, and at the same time controls the corresponding sealing slide plate 142 to be in the open state, so that the waste in the tray 33 is poured into the corresponding waste storage box 4.

[0099] S3, determine whether each garbage storage bin 4 is full and display it on the electronic display screen 71, and stop garbage feeding when the garbage storage bin 4 is full;

[0100] S4, after the waste is sorted and stored in the corresponding waste storage bin 4, controls the crushing component to work to crush the kitchen waste and controls the compression component to work to compress the recyclable waste.

[0101] This classification and control method for waste bins ensures continuous identification of waste and allows for proper disposal according to type, thereby improving the efficiency of waste bin usage.
