DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] The embodiment of the present invention discloses a garbage intelligent sorting system. Figure 1 As shown, the invention uses bionics knowledge to miniaturize garbage treatment equipment according to the size of domestic garbage, and divides the garbage recycling machine into the following units according to the human digestive organs: AI recognition unit, cutting unit, disinfection unit, separation unit, spiral extrusion unit, screening unit, recycling unit, emptying unit and control unit;

[0034] AI recognition unit, similar to human eyes, is used to make preliminary identification of the size of garbage. If the size of garbage is not up to standard, the hatch will be closed, and if the size is up to standard, the hatch will be opened;

[0035] The cutting unit is similar to human teeth and is used to squeeze and cut the garbage of qualified size after being put into the system;

[0036] The disinfection unit is similar to the immune system. It disinfects the cut garbage by spraying disinfectant and ultraviolet scanning, so as to process harmful substances such as bacteria and viruses in the garbage and avoid virus infection during the garbage recycling process.

[0037] A separation unit is used to separate metal waste and light waste from the disinfected waste and send them to corresponding recycling units;

[0038] The spiral extrusion unit is similar to the human stomach and small intestine, and is used to spirally extrude the remaining garbage after separation to reduce the volume of the garbage, such as compressing fragile blocks (such as kitchen utensils, glass bottles, etc.) or non-ferrous shells such as cans;

[0039] The screening unit, similar to the human large intestine, is used to sort and screen the garbage after spiral extrusion through steel screens of different particle sizes, separating batteries, stones and plastics into corresponding recycling units;

[0040] A recovery unit for recovering and discharging the remaining domestic waste residues and non-recyclable materials after screening, such as sewage, and for recovering the garbage discharged from the separation unit, the screening unit and the emptying unit;

[0041] The emptying unit is used to empty the abnormal garbage in the AI ​​recognition unit, cutting unit, disinfection unit, separation unit, spiral extrusion unit and screening unit, and discharge the abnormal garbage to the recycling unit; the emptying operation is the self-protection unit of the system. When encountering abnormal garbage that cannot be processed (abnormal iron objects or bricks, etc.), all subsequent operations are directly emptied, the garbage is placed in the recycling unit, and then an alarm is issued for processing;

[0042] A control unit is used to control the AI ​​recognition unit, the cutting unit, the disinfection unit, the separation unit, the spiral extrusion unit, the screening unit and the emptying unit.

[0043] Further, if Figure 3 As shown, the recycling unit includes a recyclable trash can 24 and a non-recyclable trash can 23. The separation unit and the screening unit discharge the separated and screened garbage into the recyclable trash can 24, and discharge the remaining domestic waste and non-recyclable materials after screening and the garbage discharged by the emptying unit into the non-recyclable trash can 23.

[0044] Further, if Figure 2 As shown, the AI ​​recognition unit includes a camera 1, a garbage bin 2 and a hatch 3. The camera 1 is installed on the top of the front of the garbage bin 2, and the hatch 3 is located at the bottom of the camera 1. It is similar to the eyes and mouth of a person checking the garbage entry hatch. The camera 1 and the machine recognition algorithm (such as the AI ​​classification algorithm for garbage classification) are used to achieve preliminary discrimination of the garbage capacity and the harmful properties of the garbage. If the size is not appropriate, it is prompted to manually split it into the appropriate size. The controller controls the hatch 3 not to open. When the size is qualified, the hatch 3 is opened. Specifically, the hatch adopts a circular spiral door, including an aperture assembly, and the aperture assembly includes an aperture, a connecting rod and a driving wheel. The controller drives the opening and closing of the aperture by controlling the rotation of the driving wheel. According to the size of the garbage, the mechanical aperture is controlled by the motor to control the size of the opening and closing of the recycling hatch to avoid damage to the equipment operation.

[0045] Further, if Figure 3, Figure 4 As shown, the cutting unit includes a pressure sensor 4, a cutting wheel 5, a fixed plate 6, a hydraulic lifting column 7, an electric push rod 8, and a tray 9. The fixed plate 6 is installed on the top plate inside the garbage box 2 through the hydraulic lifting column 7. The pressure sensor 4 is fixed on the top of the fixed plate 6. The bottom of the fixed plate 6 is provided with a cutting track 10. The cutting wheel 5 is arranged in the cutting track 10. The tray 9 is two semicircular trays. The two sides of each semicircular tray are respectively hinged with the electric push rod 8. The other end of the electric push rod 8 is hinged with the first fixed column or the second fixed column. After the garbage passes through the AI ​​recognition unit, the garbage falls on the tray. At this time, the electric push rod 8 is in an extended state, and the two semicircular trays 9 are just closed to hold the garbage. When the garbage falls on the tray 9, the hydraulic lifting column 7 moves, driving the fixed plate 6 to move downward. When the fixed plate and the tray squeeze the garbage, the pressure sensor 4 is used to determine whether to cut the garbage through the squeezing force between the fixed plate and the tray. For example, it is set to cut when the pressure value is equal to 5 kg, and the cutting wheel performs rotating squeezing cutting. Otherwise, the cutting wheel does not operate. The cutting wheel uses a steel cutting blade for rotary extrusion cutting to ensure the adequacy of the cutting and packaging process. When the garbage is cut, the electric push rod 8 is extended and retracted, and the two semicircular trays 9 are separated, and the garbage falls into the spiral extrusion unit.

[0046] The cutting unit of the present invention takes into account the situation that packaging that is difficult to cut, such as woven bags, needs to be cut, and changes the electric heat cutting into pressure cutting.

[0047] Further, if Figure 3 , Figure 4 As shown, the separation unit includes an electromagnet and a fan 11, which are located on opposite sides of the fixed plate 6, the fan 11 is fixed on one side surface inside the garbage bin 2, the electromagnet is fixed in a fixed frame 12, the fixed frame 12 is fixed inside the garbage bin 2, a through hole 13 is provided on a side of the fixed frame 12 opposite to the fan, the electromagnet is used to attract metal garbage, the metal garbage is sucked into the fixed frame through the through hole, and the metal garbage falls into the recyclable garbage bin 24 through the opening at the bottom of the fixed frame 12, the fan is used to blow light garbage with light weight into the fixed frame 12 through the through hole by wind force, and the light garbage falls into the recyclable garbage bin 24 through the opening at the bottom of the fixed frame 12.

[0048] After the cutting is completed, the disinfection unit is started for disinfection, and after the disinfection is completed, the separation unit is started to recycle metal materials containing raw materials such as iron, nickel, cobalt, and lightweight paper and plastic barrels, and the metal materials fall into the corresponding recyclable garbage bin after power failure.

[0049] Further, if Figure 3 , Figure 4As shown, the spiral extrusion unit includes a main crushing wheel 14, a secondary crushing wheel 15, a hydraulic push rod 27, a first motor 25, a second motor 26, a first fixed rod 16 and a second fixed rod 17. The main crushing wheel 14 and the secondary crushing wheel 15 are connected to the output shafts of the first motor 25 and the second motor 26 respectively. The first motor 25 drives the main crushing wheel 14 to rotate, and the second motor 25 drives the secondary crushing wheel 15 to rotate. The main crushing wheel 14 and the secondary crushing wheel 15 rotate in opposite directions, that is, the main crushing wheel 14 rotates clockwise, and the secondary crushing wheel 15 rotates counterclockwise. In this embodiment, the first motor 25 and the second motor 26 are fixed on the same side of the crushing wheel, that is, they are fixed in the first fixed rod 16 or the second fixed rod 17 at the same time, and the first fixed rod 16 and the second fixed rod 17 are hollow structures, as shown in FIG. Figure 5 , 6 As shown, the first motor and the second motor are fixed in the first fixed rod 16, the second motor 26 is connected to the hydraulic push rod 27 through the connecting plate 28, the hydraulic push rod 27 is fixed in the first fixed rod 16, and the second motor 26 is moved toward or away from the first motor by controlling the extension and contraction of the hydraulic push rod 27. The first fixed rod 16 and the second fixed rod 17 are both provided with openings 29 of the same length on the inner side, and the length of the opening 29 determines the distance moved by the slave crushing wheel. When moving to the end point closest to the main crushing wheel, the distance between the main crushing wheel and the slave crushing wheel is 0.8 cm. Slide blocks 30 and slide rails are provided at the openings, and the slide blocks 30 are provided on the slide rails. The slide blocks 30 are provided with second bearings, which are sleeved on the outer surface of the output shaft of the second motor 26. The output shaft of the second motor is connected to the center of the slave crushing wheel 15 from one end of the crushing wheel, and extends from the other end to be connected to the slide block in the second fixed rod. The output shaft of the first motor 25 is connected to the center of the main crushing wheel 14, and the two ends of the first motor 25 are respectively connected to the first bearings located in the first fixed rod and the second fixed rod.

[0050] The first fixed column 18 is fixed on one side surface inside the garbage bin 2, on the same side as the fan, and the second fixed column 19 is fixed on the fixed frame 12. When the garbage falls into the spiral extrusion unit, the main crushing wheel 14 and the slave crushing wheel 15 rotate towards each other. During normal rotation, a certain gap is maintained between the main crushing wheel and the slave crushing wheel. The gap is the shortest distance between the main crushing wheel and the slave crushing wheel, and the value range is 0.8 cm. When the garbage is squeezed, the garbage can be automatically dropped. If during the extrusion process, if the motor feedback force is greater than the threshold, it means that the extrusion may be caused by glass bottles, ceramic pieces and batteries. The hydraulic cross bar is controlled to contract, driving the slave crushing wheel to rotate away from the main crushing wheel, and the garbage falls. The present invention prevents glass bottles, ceramic pieces and batteries from being squeezed and damaged by the squeeze force by controlling the flexible extrusion force (adjusting the hydraulic push rod strength by rotating pressure feedback).

[0051] Further, if Figure 3 and Figure 4As shown, the screening unit includes a first steel screen 20, a second steel screen 21, and a third steel screen 22. The first steel screen 20, the second steel screen 21, and the third steel screen 22 are tilted, and the two ends of the first steel screen 20, the second steel screen 21, and the third steel screen 22 are fixed on the first fixed column and the second fixed column by springs. The first steel screen 20, the second steel screen 21, and the third steel screen 22 are vibrated by a vibrator, and the vibrator can be set at the bottom of the first steel screen 20, the second steel screen 21, and the third steel screen 22. The first steel screen 20, the second steel screen 21, and the third steel screen 22 are provided with different apertures, and the apertures of the first steel screen 20, the second steel screen 21, and the third steel screen 22 are successively smaller. Specifically, the aperture of the first steel screen 20 can be set to 1.5 cm, the aperture of the second steel screen can be set to 1 cm, and the aperture of the third steel screen can be set to 0.8 cm. It can be set according to actual conditions, and the specific size of the steel screen aperture is not specifically limited.

[0052] The present invention performs three-stage separation according to the different specific gravities and diameters of garbage materials. The first steel screen, the second steel screen and the third steel screen are vibrated by a vibrator, and the above untreated harmful materials such as batteries, stones and hard plastics are separated by an inclined structure and fall into the recyclable garbage bin 24. The screened kitchen waste and non-recyclable materials are placed in the non-recyclable garbage bin 23 for later landfill and biological fermentation to perform deodorization and recycling operations.

[0053] The workflow of the present invention is as follows Figure 7 As shown, the AI ​​recognition unit makes a preliminary judgment on the garbage to be processed. The hatch opens only when the size is qualified, and the garbage enters the cutting unit. When the garbage falls on the tray, the hydraulic lifting column moves, driving the fixed plate to move downward. The fixed plate and the tray squeeze the garbage. The pressure sensor determines whether to cut the garbage through the pressure between the fixed plate and the tray. If the preset pressure is met, the controller controls the cutting wheel to cut. When the garbage is cut, the electric push rod is extended and retracted, and the two semicircular trays are separated. The garbage falls into the spiral extrusion unit and is squeezed by the main crushing wheel and the secondary crushing wheel. After the extrusion is completed, the main crushing wheel and the secondary crushing wheel are separated, and the garbage falls into the screening unit through the gap between the main crushing wheel and the secondary crushing wheel. The screening unit vibrates the recyclable garbage into the recyclable garbage bin, and the kitchen waste and non-recyclable materials are placed in the non-recyclable garbage bin through the rigid sieve aperture for later landfill and biological fermentation for deodorization and recovery operations.
