[0030] By setting up a screening section in the sorting bin 1, the garbage can be initially screened, and loose garbage and packaged garbage can be initially classified to facilitate subsequent garbage disposal. The first transport section and the bag-breaking section set up in the bag-breaking bin 3 can break up the packaged garbage and process it into loose garbage. The loose garbage screened by the screening section and the loose garbage after bag breaking are respectively sent to the transfer bin 5 through the first channel 2 and the second channel 4. During the process of entering the transfer bin 5, the first air separation section and the second air separation section set up blow the lightweight garbage, such as plastic products and paper products, into the collection bin 6 to complete the classification of lightweight garbage and other garbage. The sorted other garbage is transferred to the crushing mechanism for crushing under the transport of the second transport section. The crushing mechanism can separate glass products, such as various glass bottles for holding seasonings, from the other garbage for recycling and reuse. The separated other garbage is crushed by the crushing mechanism and then transferred to the dosing and stirring mechanism for dosing and stirring. After the dosing and stirring treatment is completed, it is buried or incinerated.

[0031] The scheme is further optimized. The screening section includes a sorting frame 7. Several lugs 10 are fixedly connected to the outer wall of the sorting frame 7. A first connecting seat 8 is fixedly connected to the inner wall of the sorting chamber 1. The lugs 10 are rotatably connected to the first connecting seat 8 through a first hinge shaft 9. Several dividing rods 29 are fixedly connected inside the sorting frame 7. The dividing rods 29 are arranged in parallel and at equal intervals.

[0033] Household waste that needs to be processed is put into the sorting bin 1 through the first funnel 50 and falls onto the sorting frame 7. Then, the linear reciprocating motor 15 starts to work, driving the sorting frame 7 to vibrate up and down continuously. During the vibration, loose waste is separated from packaged waste. Loose waste falls into the first channel 2, while packaged waste enters the bag breaking bin 3 for further processing.

[0034] The scheme is further optimized. The first air separation unit includes a first air inlet pipe 17. The end of the first air inlet pipe 17 is fixedly connected to the side wall of the first channel 2. A first fan 18 is fixedly installed inside the first air inlet pipe 17.

The third channel 19 and the first air inlet pipe 17 are symmetrically arranged on both sides of the first channel 2. The other end of the third channel 19 is fixedly connected to the side wall of the collection chamber 6.

[0035] After the loose waste enters the first channel 2, the first fan 18 blows air to separate the lightweight waste from the other waste. The lightweight waste enters the collection bin 6 under the blowing action of the first fan 18, while the other waste falls into the transfer bin 5 for further processing.

[0036] The scheme is further optimized. The second air separation unit includes a second air inlet pipe 25. The end of the second air inlet pipe 25 is fixedly connected to the side wall of the second channel 4. A second fan 26 is fixedly installed inside the second air inlet pipe 25. One end of a fourth channel 27 is also fixedly connected to the side wall of the second channel 4. The fourth channel 27 and the second air inlet pipe 25 are symmetrically arranged on both sides of the second channel 4. The other end of the fourth channel 27 is fixedly connected to the side wall of the collection chamber 6. A chamber cover 28 is hinged to the top of the collection chamber 6.

[0037] Loose waste processed from the packaged waste enters the second channel 4. The processing in the second channel 4 is the same as that in the first channel 2. The processed lightweight waste enters the collection bin 6, while other waste falls into the transfer bin 5 for further processing.

[0038] The scheme is further optimized. The first transport section includes a first active roller 21. One end of the first active roller 21 is rotatably connected to the inner wall of the bag breaking chamber 3. The other end of the first active roller 21 is fixedly connected to the output shaft of the first transport motor.

The several protrusions 24 are evenly arranged. The bag breaking section is located above the first belt 22.

[0039] Furthermore, a second funnel 20 is fixedly connected to the top of the bag-breaking chamber 3.

[0040] The design is further optimized so that the bag breaking part includes a second connecting seat 11, which is fixedly connected to the top wall of the bag breaking chamber 3. One end of the bag breaking knife 13 is rotatably connected to the second connecting seat 11 through the second hinge shaft 12. One end of the spring 14 is fixedly connected to the top of the other end of the bag breaking knife 13, and the other end of the spring 14 is fixedly connected to the top wall of the bag breaking chamber 3.

[0041] After the packaged waste enters the bag-breaking chamber 3, it is transported forward by the first belt 22. During the transportation process, the spring 14 drives the bag-breaking knife 13 to cut the outer bag of the packaged waste. After cutting, the waste inside the outer bag falls into the second channel 4, where it is sorted and processed into lightweight waste and other waste.

[0042] In a further optimized design, the second transport section includes a second drive roller 30. One end of the second drive roller 30 is rotatably connected to the inner wall of the transfer chamber 5, and the other end of the second drive roller 30 is fixedly connected to the output shaft of a second transport motor. The second transport motor is fixedly connected to the inner wall of the transfer chamber 5. The second drive roller 30 is driven by a second driven roller 32 via a second belt 31. Both ends of the second driven roller 32 are rotatably connected to the inner wall of the transfer chamber 5. An inclined material plate 33 is provided on the side of the second driven roller 32 away from the second drive roller 30. The inclined material plate 33 is fixedly connected to the inner wall of the transfer chamber 5. The high end of the inclined material plate 33 contacts the outer wall of the second belt 31, and the bottom end of the inclined material plate 33 is located outside the transfer chamber 5.

[0043] All other sorted waste in the first channel 2 and the second channel 4 falls onto the second conveyor belt 31, which then transfers it to the crushing chamber 34. The inclined material plate 33 scrapes off the waste from the surface of the second conveyor belt 31 to prevent it from adhering to the surface.

[0044] The crushing mechanism is further optimized by including a crushing chamber 34 located below the end of the transfer chamber 5.

The first rotating shaft 36 is located inside the transfer chamber 5. A plurality of first cutting blades 37 are fixedly connected to the outer wall of the first rotating shaft 36. The plurality of first cutting blades 37 are equally spaced along the circumference and axial direction of the first rotating shaft 36. A plurality of second cutting blades 38 are also fixedly connected to the outer wall of the first rotating shaft 36. The plurality of second cutting blades 38 are located below the first cutting blades 37 and are equally spaced along the axial direction of the first rotating shaft 36. The length of the second cutting blades 38 is shorter than that of the first cutting blades 37. A plurality of rotating shafts 39 are rotatably connected to the top of the inner wall of the crushing chamber 34. The distance between any two adjacent rotating shafts 39 increases sequentially in the direction away from the transfer chamber 5. A crushed material transfer part is fixedly connected to the bottom of the side wall of the crushing chamber 34 away from the transfer chamber 5.

[0045] After other waste is transported out of the transfer chamber 5, it first falls onto several rotating shafts 39. Each rotating shaft 39 is driven by a rotary drive motor. During the rotation, glass products such as soy sauce bottles in the other waste are trapped on the rotating shaft 39, while the other waste falls into the crushing chamber 34 for crushing. The distance between any two adjacent rotating shafts 39 increases sequentially in the direction away from the transfer chamber 5, which can trap glass bottles of different diameters. After the waste is crushed, it is transferred by the crushed material transfer unit to the mixing chamber 43 for further processing.

[0046] The further optimized design includes a material transfer unit comprising a discharge bin 40. One end of the discharge bin 40 is fixedly connected to the side wall of the crushing chamber 34, and the other end of the discharge bin 40 is fixedly connected to a second motor 41. The output shaft of the second motor 41 is fixedly connected to one end of a discharge auger 42. The discharge auger 42 is rotatably disposed inside the discharge bin 40, and the other end of the discharge auger 42 is located inside the crushing chamber 34. The chemical dosing and stirring mechanism is located below the outlet end of the discharge bin 40.

[0047] The crushed waste is driven by the rotation of the discharge auger 42 from the crushing chamber 34 into the discharge chamber 40, and then falls from the outlet end of the discharge chamber 40 into the mixing chamber 43 for further processing.

[0048] The scheme is further optimized. The dosing and mixing mechanism includes a mixing chamber 43, which is located below the outlet end of the discharge chamber 40.

A discharge pipe 48 is fixedly connected to the bottom of the side wall of the mixing chamber 43 away from the crushing chamber 34. An electrically controlled valve 49 is installed on the discharge pipe 48.

[0049] After the crushed waste enters the mixing chamber 43, the medicine tank 47 adds treatment medicine into the mixing chamber 43, and then the mixing shaft 46 mixes the waste to make the treatment medicine and waste evenly mixed. After the mixing is completed, it is discharged through the discharge pipe 48 for landfill or incineration.

[0050] The working process of this embodiment is as follows:

[0051] Household waste is first put into sorting bin 1 to separate loose waste from packaged waste. Loose waste enters the first channel 2 for air separation, which separates lightweight waste. At the same time, packaged waste enters the bag-breaking bin 3 for bag breaking. Loose waste after bag breaking enters the second channel 4 for air separation, which separates lightweight waste. Other waste after air separation in the first channel 2 and the second channel 4 enters the transfer bin 5 for transportation and transfer. It is then transported to the crushing bin 34. During the process in the crushing bin 34, the rotating shaft 39 separates glass bottles from other waste. The glass bottles are recycled and reused, while the other waste is crushed. After crushing, the waste enters the mixing bin 43 for chemical dosing and mixing. The mixed waste is discharged through the discharge pipe 48 for further processing.
