[0002] With the acceleration of urbanization, the garbage problem is becoming increasingly serious. "Garbage classification" has gradually become a topic of common concern around the world. As a populous country, my country has started to take measures to classify garbage since 2019. The intelligent garbage classification and recycling device can efficiently and accurately classify garbage, reduce environmental pollution, and improve resource recycling. Intelligent management can not only reduce labor costs, but also promote sustainable development and enhance the public's environmental awareness.

[0003] The existing garbage classification generally relies on the public's conscious classification and disposal. However, since the public often makes mistakes in the classification process, it is necessary to go through the garbage recycling station for secondary classification, which consumes a lot of manpower and material resources and may also cause waste of renewable resources. At the same time, since most people put the garbage in garbage bags and mix them together, the pressure of recycling is further increased. In addition, the recyclable garbage contains a large number of large hollow items such as plastic bottles, which occupy a considerable part of the space, resulting in low space utilization in the garbage bin, making the garbage easily overflow. Summary of the invention

[0010] As a further solution of the present invention, the racket bar includes a rotating track, a screw, a nut, an upper slot, a lower slot, a spring and a roller. The nut on the upper part of the racket bar is engaged with the screw in the middle of the rotating track, the screw is driven by a motor, the upper slot and the lower slot are located at the bottom of the racket bar, the middle of the upper slot and the lower slot are connected by a spring, and the roller is engaged with the bottom end of the lower slot.

[0011] As a further solution of the present invention, the compression device includes a needle plate, a compression plate with holes, an upper connecting rod, a lower connecting rod, a compression plate connecting rod, a needle plate connecting rod, a second motor, a small gear and a large gear. The needle plate is fixedly connected to the needle plate connecting rod, the compression plate with holes is fixedly connected to the compression plate connecting rod, the needle plate connecting rod is connected to the lower connecting rod through a pin, and the compression plate connecting rod is connected to the upper connecting rod through a pin.

[0012] As a further solution of the present invention, the upper connecting rod is fixed to the upper surface of the large gear by pin A, and the lower connecting rod is fixed to the lower surface of the large gear by pin B, and the fixed positions maintain a certain distance on the same circumference, the large gear and the small gear are meshed with each other, and the small gear is driven by motor 2.

[0013] As a further solution of the present invention, the garbage classification area includes a recyclable garbage area, a kitchen waste area, a hazardous waste area and other garbage areas, and each area is provided with an insect repellent and deodorization device and a garbage capacity detection device.

[0014] In addition, the present invention also provides a working method of an intelligent garbage classification and compression device, comprising the following steps:

[0015] Step 1: When the garbage bag is hung on the hook, the hook will move the garbage bag along the track to the inside of the bag pouring device and place it above the bottom plate. Then the gear rotates so that the fixing device clamps and fixes the garbage bag body. Then the three clamps clamp the three openings of the garbage bag under the control of the mechanical arm. Then the cutting device cuts the upper part of the tied garbage bag, and then the bag-supporting device opens the opening of the garbage bag. After that, the entire bag-supporting device and the fixing device will rotate 180° along the rotating shaft, so that all the garbage falls onto the first conveyor belt, thereby ensuring the smooth operation of the device. Then two of the clamps are released, and the remaining clamp sends the garbage bag into the recyclable garbage area. Then the entire bag pouring device returns to normal again under the drive of the rotating shaft. If the garbage is put into this device individually, the bag pouring device will not operate, and the first conveyor belt will start to operate directly under the control of the intelligent speed control device.

[0016] Step 2: After the bag dumping device dumps all the garbage onto the first conveyor belt, the scraper will maintain a certain distance from the first conveyor belt in the vertical direction and move horizontally to disperse the garbage to a certain extent. Then the first conveyor belt will move slowly to make the garbage fall evenly and slowly onto the second conveyor belt. During this period, the garbage will be dispersed to a certain extent through the diversion rod. At the same time, the second conveyor belt will rotate to make the garbage pass through the dispersion surface to be further distanced. Through this process, each piece of garbage will be dispersed.

[0017] Step 3: After the garbage is completely dispersed, it is transported to the sorting device. At this time, the intelligent recognition camera begins to identify and determine the type of garbage. If it is recyclable garbage or kitchen waste, it will be tracked and identified in the area responsible for the first pole and quickly hit the corresponding garbage area. If it is hazardous waste or other garbage, it will be tracked and identified in the area responsible for the second pole and quickly hit the corresponding garbage area. At the same time, the intelligent recognition camera will control the pole to move along the rotating track with the garbage, and then quickly and accurately rotate 360° clockwise or counterclockwise to make the garbage fall into the corresponding area. When the pole contacts the edge of the sorting device, the roller begins to roll under the action of friction and drives the lower slot compression spring, so that the pole can contact the garbage scattered in all parts of the conveyor belt.

[0018] Step 4: If the intelligent recognition camera identifies the garbage as compressible garbage such as plastic bottles and cans among recyclable garbage, the bottom plate remains closed. The compression device begins to compress under the action of motor 2, where the upper connecting rod and the lower connecting rod are respectively fixed to the upper surface and lower surface of the large gear by pin A and pin B, but the fixed positions are kept at a certain distance on the same circumference. The initial state of the compression device is as follows: Figure 7, pin A and pin B are both on the left side of the large gear. When the garbage falls into the gap between the perforated compression plate and the box, motor 2 starts to drive the small gear to rotate, and then drives the large gear to rotate clockwise. In this process, pin B reaches the right side of the large gear before pin A. Figure 8 As shown, during this process, the needle plate first contacts the garbage such as plastic bottles and cans, and plays a role in breaking and compressing. Then the large gear continues to rotate clockwise, and the pin B rotates to the lower left accordingly, while the pin A reaches the right side of the large gear, as shown in FIG. Fig. 9 As shown in the figure, during this process, the perforated compression plate begins to compress the garbage and pushes it off the needle plate to achieve a further compression effect. Then the large gear continues to rotate clockwise until Figure 7 The state shown is ready for the next compression. At this time, the bottom plate will rotate through the hinge to make the garbage fall into the recyclable garbage area. If the recyclable garbage identified is garbage that does not need to be compressed, the compression device will not operate and the bottom plate will directly rotate open to make the garbage fall into the recyclable garbage area.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The intelligent garbage classification and compression device and its working method can fully and completely separate the garbage from the garbage bag through the bag dumping device, so that different types of garbage can be accurately classified, and the garbage can be accurately sent to the corresponding garbage classification area, which reduces the difficulty of garbage classification and improves the efficiency of subsequent classification.

[0021] 2. The intelligent garbage classification and compression device and its working method can realize automatic classification of garbage by setting up an intelligent speed control device, an intelligent recognition camera and an intelligent sorting device, so as to realize intelligent recognition and accurate sorting of garbage after the garbage is fully dispersed, thereby improving the recycling rate of resources and reducing labor costs.

[0022] 3. The intelligent garbage classification and compression device and its working method can effectively improve the space utilization rate in the garbage bin through the compression device, so that plastic bottles, cans and other items that occupy the majority of recyclable garbage can be compressed, wherein the needle plate can break open the closed plastic bottles to prevent explosion during compression.

[0023] 4. The intelligent garbage sorting and compression device and its working method can effectively reduce the breeding of bacteria and viruses, repel insects and reduce odors through the installation of an insect repellent and deodorizing device inside the garbage can, thereby greatly reducing the possibility of environmental pollution and virus transmission.

Obviously, the described embodiments are only part of the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0035] See also Figure 1-9 The present invention provides a technical solution: an intelligent garbage sorting and compression device, comprising a box body 1, the interior of the box body 1 includes a garbage delivery port 17, a garbage bag conveying track 3 and a bag pouring device 2. The garbage bag conveying track 3 is nested with a hook 4, and the bag pouring device 2 is combined with the box body 1 through a U-shaped frame 2-1. A cutting device 2-2 is fixed to the upper part of the U-shaped frame 2-1, and a horizontal telescopic track 2-3 is fixed to the lower part of the cutting device 2-2. The cutting device 2-2 can move forward and backward along the horizontal telescopic track 2-3, and the cutting device 2-2 can rotate at a certain speed, so that the upper part of the garbage bag can be effectively broken without affecting the garbage bag being fed into the bag pouring device 2.

[0036] The U-shaped frame 2-1 is connected to a fixing device 2-4 and a bag-supporting device 2-5 through a rotating shaft 2-6, and the bottom of the fixing device 2-4 is connected to a bottom plate 2-7. The fixing device 2-4 includes an arc-shaped fixing surface 2-11 staggered up and down and a gear 2-10, and the bag-supporting device 2-5 includes three groups of clamping plates 2-8 and a mechanical arm 2-9. The arc-shaped fixing surfaces 2-11 staggered up and down on both sides are an upper arc surface and a lower arc surface, respectively, so that the arc surfaces on both sides can be fully meshed during the operation of the gear 2-10, and at the same time, the garbage bag body can be better fixed and effectively rotated.

[0037] The first conveyor belt 6, the second conveyor belt 9 and the third conveyor belt 11 are arranged below the bag pouring device 2. The intelligent speed control device 8 is arranged on the right side of the second conveyor belt 9, and the diverter rod 7 is arranged above the second conveyor belt 9.

The second conveyor belt 9 and the third conveyor belt 11 are connected by a dispersion surface 10, and the dispersion surface 10 is composed of cylindrical rollers 23 arranged in a trapezoidal shape. The three conveyor belts of the second conveyor belt 9 are parallel to each other and have a very small gap in the middle, thereby preventing the garbage from interfering with the conveyor belt transmission while pulling the distance of the garbage in the same horizontal direction. There is also a very small gap between the cylindrical rollers 23 of the dispersion surface 10, and the cylindrical rollers 23 can rotate around the horizontal axis, so that the garbage can be effectively dispersed when passing through the dispersion surface 10.

[0038] Two intelligent recognition cameras 13 are arranged on the left side of the sorting device 14, and the two intelligent recognition cameras 13 are fixed on the box body 1. The main body of the sorting device 14 is a conveyor belt, and two groups of rackets 12 are arranged on the upper part of the sorting device 14, and the rackets 12 are engaged with the rotating track 12-1, and the rotating track 12-1 is driven by a motor 18. The nut 12-3 on the upper part of the racket 12 is engaged with the screw 12-2 in the middle of the rotating track 12-1, and the screw 12-2 is driven by a motor 18. The nut 12-3 and the screw 12-2 are screwed together, and the nut 12-3 and the racket 12 are completely fixed, thereby ensuring that when the screw 12-2 rotates, the nut 12-3 can drive the racket 12 to move forward and backward accurately. The bottom of the racket 12 is provided with an upper groove 12-4 and a lower groove 12-5, the middle of the upper groove 12-4 and the lower groove 12-5 are connected by a spring 12-6, and the bottom end of the lower groove 12-5 is fitted with a roller 12-7. A small gap is left between the upper groove 12-4 and the lower groove 12-5 to ensure that the lower groove 12-5 can smoothly compress the spring 12-6 and retract it, and the roller 12-7 is connected to the lower groove 12-5 through a pin and has a small gap with the inner wall of the lower groove 12-5 to ensure that the roller 12-7 can rotate flexibly.

[0039] A compression device 16 is provided below the sorting device 14. The compression device 16 is composed of a needle plate 16-1 and a compression plate with holes 16-2. The needle plate 16-1 is fixedly connected to a needle plate connecting rod 16-6. The compression plate with holes 16-2 is fixedly connected to a compression plate connecting rod 16-5. The needle plate connecting rod 16-6 is connected to a lower connecting rod 16-4 through a pin. The compression plate connecting rod 16-5 is connected to an upper connecting rod 16-3 through a pin. The upper connecting rod 16-3 is fixed to the upper surface of a large gear 16-9 through a pin A 16-10. The lower connecting rod 16-4 is fixed to the lower surface of the large gear 16-9 through a pin B 16-11. The fixed positions are kept at a certain distance on the same circumference. The large gear 16-9 is meshed with a small gear 16-8. The small gear 16-8 is driven by a motor 2 16-7.

[0040] A bottom plate 2 15 is provided below the compression device 16, and the bottom plate 2 15 is connected to the box body 1 through a hinge 22. The positions of the needles on the needle plate 16-1 and the holes on the perforated compression plate 16-2 correspond one to one, so that the needles can be freely extended and retracted at the positions of the holes. A hole is reserved on the needle plate 16-1 for the compression plate connecting rod 16-5 to extend and retract, so that the perforated compression plate 16-2 can be freely extended and retracted under the drive of the compression plate connecting rod 16-5.

[0041] The lower part of the box body 1 is provided with a garbage classification area 19, which includes a recyclable garbage area 19-1, a kitchen waste area 19-2, a hazardous waste area 19-4 and an other garbage area 19-3, and each area is provided with an insect repellent and deodorizing device 21 and a garbage capacity detection device 20. The insect repellent and deodorizing device 21 is located at the connection position of each area, and a solid volatile insect repellent and deodorizing agent is placed inside, which can ensure long-term and effective insect repellent and deodorization. The garbage capacity detection device 20 is located at the upper part of each area, and uses the infrared sensing principle to automatically detect and warn whether the garbage classification area 19 is overflowing.

[0042] The working method of the intelligent garbage classification and compression device comprises the following steps:

[0043] Step 1: When the garbage bag is hung on the hook 4, the hook 4 will move the garbage bag along the track 3 to the inside of the bag pouring device 2 and place it above the bottom plate 2-7. Then the gear 2-10 rotates so that the fixing device 2-4 clamps and fixes the garbage bag body. Then the three clamps 2-8 clamp the three openings of the garbage bag respectively under the control of the mechanical arm 2-9. Then the cutting device 2-2 cuts the upper part of the tied garbage bag, and then the bag-supporting device 2-5 opens the garbage bag. After that, the entire bag-supporting device 2-5 and the fixing device 2-4 will rotate 180° along the rotating shaft 2-6, so that all the garbage falls onto the first conveyor belt 6, thereby ensuring the smooth operation of the device. Then two of the clamps 2-8 are loosened, and the remaining clamp 2-8 sends the garbage bag into the recyclable garbage area 19-1. Then the entire bag pouring device 2 returns to normal again under the drive of the rotating shaft 2-6. If the garbage is put into the device individually, the bag pouring device 2 will not operate, and the first conveyor belt 6 will start to operate directly under the control of the intelligent speed control device 8.

[0044] Step 2: After the bag dumping device 2 dumps all the garbage onto the first conveyor belt 6, the scraper 5 maintains a certain distance from the first conveyor belt 6 in the vertical direction and moves in the horizontal direction, so that the garbage is dispersed to a certain extent. Then the first conveyor belt 6 moves slowly so that the garbage falls evenly and slowly onto the second conveyor belt 9. During this period, the garbage is dispersed to a certain extent through the diverter rod 7. At the same time, the second conveyor belt 9 rotates so that the garbage passes through the dispersion surface 10 and is further distanced. Through this process, each piece of garbage is dispersed.

[0045] Step 3: After the garbage is completely dispersed, it is transported to the sorting device 14. At this time, the intelligent recognition camera 13 starts to recognize and determine the type of garbage. If it is recyclable garbage or kitchen waste, it will be tracked and identified in the area responsible for the first racket 12 and quickly hit the corresponding garbage area. If it is hazardous garbage or other garbage, it will be tracked and identified in the area responsible for the second racket 12 and quickly hit the corresponding garbage area. At the same time, the intelligent recognition camera 13 will control the racket 12 to move along the rotating track 12-1 with the garbage, and then quickly and accurately rotate 360° clockwise or counterclockwise to make the garbage fall into the corresponding area. When the racket 12 contacts the edge of the sorting device 14, the roller 12-7 starts to roll under the action of friction and drives the lower groove 12-5 to compress the spring 12-6, so that the racket 12 can contact the garbage scattered in all parts of the conveyor belt.

[0046] Step 4: If the intelligent recognition camera 13 recognizes that the garbage is compressible garbage such as plastic bottles and cans among recyclable garbage, the bottom plate 15 remains closed. The compression device 16 starts to compress under the action of the motor 2 16-7, wherein the upper connecting rod 16-3 and the lower connecting rod 16-4 are respectively fixed to the upper surface and the lower surface of the large gear 16-9 by the pin A 16-10 and the pin B 16-11, but the fixed positions are kept at a certain distance on the same circumference. The initial state of the compression device 16 is as follows: Figure 7 , pin A 16-10 and pin B 16-11 are both on the left side of the large gear. When the garbage falls into the gap between the perforated compression plate 16-2 and the box 1, the motor 2 16-7 starts to drive the small gear 16-8 to rotate, and then drives the large gear 16-9 to rotate clockwise. In this process, pin B 16-11 reaches the right side of the large gear 16-9 before pin A 16-10. Figure 8 As shown, during this process, the needle plate 16-1 first contacts the garbage such as plastic bottles and cans, and plays the role of breaking and compressing. Then the large gear 16-9 continues to rotate clockwise, and the pin B 16-11 rotates to the lower left accordingly, and the pin A 16-10 reaches the right side of the large gear 16-9, as shown in FIG. Fig. 9 As shown, during this process, the perforated compression plate 16-2 begins to compress the garbage and pushes the garbage off the needle plate 16-1 to achieve a further compression effect. Then the large gear 16-9 continues to rotate clockwise to Figure 7 The state shown is ready for the next compression. At this time, the bottom plate 15 will rotate through the hinge 22, so that the garbage falls into the recyclable garbage area 19-1. If the recyclable garbage identified is garbage that does not need to be compressed, the compression device 16 will not operate and the bottom plate 15 will directly rotate open to allow the garbage to fall into the recyclable garbage area 19-1.

Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.

9. The intelligent garbage classification and compression device according to claim 1, characterized in that: The garbage classification area (19) comprises a recyclable garbage area (19-1), a kitchen waste area (19-2), a hazardous waste area (19-4) and an other garbage area (19-3), and each area is provided with an insect repellent and deodorizing device (21) and a garbage capacity detection device (20).

10. A working method of an intelligent garbage classification and compression device according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: When the garbage bag is hung on the hook (4), the hook (4) moves the garbage bag along the track (3) to the inside of the bag dumping device (2) and is placed above the bottom plate (2-7). Then the gear (2-10) rotates to make the fixing device (2-4) clamp and fix the garbage bag body. Then the three clamping plates (2-8) clamp the three openings of the garbage bag respectively under the control of the mechanical arm (2-9). Then the cutting device (2-2) cuts the upper part of the tied garbage bag, and then the bag-supporting device (2-5) opens the opening of the garbage bag. After that, the entire bag-supporting device (2-5) and the fixing device (2-4) rotate 180 degrees along the rotating shaft (2-6), so that all the garbage falls onto the first conveyor belt (6), thereby ensuring the smooth operation of the device. Then two of the clamps (2-8) are loosened, and the remaining clamp (2-8) sends the garbage bag into the recyclable garbage area (19-1), and then the entire bag pouring device (2) returns to normal again under the drive of the rotating shaft (2-6). If the garbage is put into this device individually, the bag pouring device (2) does not operate, and the first conveyor belt (6) directly starts to operate under the control of the intelligent speed control device (8). Step 2, when the bag pouring device (2) pours all the garbage onto the first conveyor belt (6), the scraper (5) and the first conveyor belt (6) maintain a certain distance in the vertical direction and move in the horizontal direction, so that the garbage is dispersed to a certain extent. Then the first conveyor belt (6) moves slowly so that the garbage falls evenly and slowly onto the second conveyor belt (9). During this period, the garbage is dispersed to a certain extent through the diverter rod (7). At the same time, the second conveyor belt (9) rotates so that the garbage passes through the dispersion surface (10) and is once again distanced. Through this process, each piece of garbage is dispersed. Step 3: After the garbage is completely dispersed, it is transported to the sorting device (14). At this time, the intelligent recognition camera (13) starts to identify and determine the type of garbage. If it is recyclable garbage or kitchen waste, it will be tracked and identified in the area responsible for the first racket (12) and quickly hit the corresponding garbage area. If it is hazardous garbage or other garbage, it will be tracked and identified in the area responsible for the second racket (12) and quickly hit the corresponding garbage area. At the same time, the intelligent recognition camera (13) controls the racket (12) to move along the rotating track (12-1) with the garbage, and then quickly and accurately rotates 360 degrees in the clockwise or counterclockwise direction, so that the garbage falls into the corresponding area. When the racket (12) contacts the edge of the sorting device (14), the roller (12-7) starts to roll under the action of friction and drives the lower groove (12-5) to compress the spring (12-6), so that the racket (12) can contact the garbage scattered in all parts of the conveyor belt. Step 4: If the intelligent recognition camera (13) recognizes that the garbage is compressible garbage such as plastic bottles and cans among recyclable garbage, the bottom plate (15) remains tightly closed.The compression device (16) starts to compress under the action of the second motor (16-7), wherein the upper connecting rod (16-3) and the lower connecting rod (16-4) are respectively fixed to the upper surface and the lower surface of the large gear (16-9) by the pin A (16-10) and the pin B (16-11), but the fixed positions maintain a certain distance on the same circumference. The initial state of the compression device (16) is shown in FIG7 . Pin A (16-10) and pin B (16-11) are both on the left side of the large gear (16-9) at this time. When the garbage falls into the gap between the perforated compression plate (16-2) and the box body (1), the motor 2 (16-7) starts to drive the small gear (16-8) to rotate, thereby driving the large gear (16-9) to rotate clockwise. In this process, pin B (16-11) reaches the right side of the large gear (16-9) before pin A (16-10), as shown in FIG8 . In this process, the needle plate (16-1) first contacts the garbage such as plastic bottles and cans, and plays a role in breaking and compressing. Then the large gear (16-9) continues to rotate clockwise, and the pin B (16-11) rotates to the lower left accordingly, and the pin A (16-10) reaches the right side of the large gear (16-9), as shown in FIG9. During this process, the perforated compression plate (16-2) begins to compress the garbage and pushes the garbage off the pin plate (16-1) to achieve a further compression effect. Then the large gear (16-9) continues to rotate clockwise to the state shown in FIG7, ready for the next compression. At this time, the bottom plate (15) rotates through the hinge (22) so that the garbage falls into the recyclable garbage area (19-1). If the recyclable garbage identified is garbage that does not need to be compressed, the compression device (16) does not operate, and the bottom plate (15) directly rotates open so that the garbage falls into the recyclable garbage area (19-1).
