Description

Technical Field

[0001] The invention belongs to the technical field of automatic garbage classification, and in particular relates to an automatic garbage classification device. Background Art

[0002] Everyone throws out a lot of garbage every day. In some areas with better garbage management, most of the garbage is disposed of harmlessly by sanitary landfill, incineration, composting, etc., while in more places, garbage is often simply piled up or buried, causing odor to spread and polluting the soil and groundwater. The purpose of garbage classification is to classify waste and use existing production and manufacturing capabilities to recycle recyclables, including material utilization and energy utilization.

[0003] From the major policies and plans for the classification of domestic waste issued by the state to the different classification policies in cities such as Shanghai, Hangzhou, Hefei and Guangzhou, various methods, publicity and education, and a large number of people participating in classification are being used. But now, it feels too troublesome, time-consuming and labor-intensive. If time goes on, we may return to the starting point. There is an urgent need to find a scientific solution and a reliable long-term mechanism.

[0004] Garbage classification generally refers to a series of activities that classify, store, place and transport garbage according to certain regulations or standards, thereby transforming it into public resources. The purpose of classification is to improve the resource value and economic value of garbage, strive to make the best use of materials, reduce the amount of garbage processed and the use of processing equipment, reduce processing costs, and reduce the consumption of land resources. It has social, economic, and ecological benefits. Judging from the methods of classifying domestic garbage in various cities at home and abroad, most of them are classified according to the composition and amount of garbage generated, combined with the local garbage resource utilization and treatment methods.

[0005] Domestic waste mainly includes the following types: kitchen waste, plastic waste, large waste, hazardous waste and other waste. According to different usage habits, the trash cans have corresponding input ports for each type of waste. Users can easily find the corresponding input ports according to the corresponding input signs and simply implement classification. However, in many cases, household waste is uniformly placed in a garbage bag, which contains plastic bottles, kitchen waste, paper, plastic bags, etc., which are in an unclassified state and many materials cannot be distinguished, requiring additional classification. Existing trash cans do not have the function of automatic garbage classification. For the mixed garbage at the front end of the garbage, it cannot be automatically classified after being put in, and cannot meet the existing requirements for garbage classification.

[0006] Therefore, the present invention mainly solves the problem that the existing garbage is mostly in a mixed state and the garbage cans are not equipped with automatic classification, resulting in the mixed garbage cannot be automatically classified; it also increases the difficulty of classifying a large amount of mixed garbage in the back-end landfill, resulting in the inability to accurately classify and recycle.

[0035] like Figure 1-4As shown: an automatic garbage sorting device, comprising a housing 1, wherein a hazardous waste bin 11, other waste bins 12, recyclable waste bins 13 and a first kitchen waste bin 14 are sequentially arranged in the housing 1, a large waste bin 15 is also arranged at the rear side of the hazardous waste bin 11, and the housings 1 corresponding to the hazardous waste bin 11, other waste bins 12, recyclable waste bins 13, the first kitchen waste bin 14 and the large waste bin 15 are all provided with garbage input ports 17;

[0036] A mixed garbage sorting machine 3 is provided on one side of the shell 1 corresponding to the first kitchen waste bin 14, for inputting mixed garbage. A mixed garbage input port 21 is provided between the shell 1 and the mixed garbage sorting machine 3, and a bag breaking device 2 is provided corresponding to the mixed garbage input port 21. The mixed garbage generally comes with a garbage bag, which can be broken by the bag breaking device. An elevator 22 is provided between the bottom of the bag breaking device 2 and the mixed garbage sorting machine 3; the broken garbage falls uniformly to the bottom, and an elevator is provided at the corresponding bottom to further transport the garbage to one side of the mixed garbage sorting machine.

[0037] The mixed garbage sorting machine 3 is provided with a first sorting section 4, a second sorting section 5 and a third sorting section 6 from top to bottom. The first sorting section 4 includes a plurality of parallel and equal-height mounted rotating shafts 41, a plurality of sorting wheels 42 are evenly sleeved on the rotating shafts 41, and a multi-toothed disc-shaped tooth 43 is sleeved on the sorting wheel 42. The corresponding sorting wheels 42 on adjacent rotating shafts 41 are arranged alternately; the two ends of the rotating shafts are correspondingly mounted on the outer shell of the mixed garbage sorting machine, and the ends are sleeved with gears. The rotating shafts are driven to rotate in the same direction by chains, transmission wheels and motors at the same time, and the garbage falling on the upper side is broken into bags for secondary separation and then moves to the other side, separating the plastic and bottles into the corresponding garbage bins; the sorting wheels are arranged alternately and have gaps. When the garbage moves, kitchen residues and other debris fall along the gaps and enter the secondary sorting section at the same time.

[0038] The second sorting section 5 includes a plurality of parallel sorting rollers 51 installed at the same height, and the sorting rollers 51 are provided with strip-shaped sorting grooves 52; the gaps between the sorting rollers are narrower, but sorting grooves for accommodating garbage are reserved for further filtering other garbage, so that kitchen waste accounts for the majority of the obtained garbage.

[0039] The third sorting section 6 comprises a plurality of parallel sorting claws 61 of equal height, and a comb-tooth-shaped support plate 63 is correspondingly arranged at the lower side of the sorting claws 61; the sorting claws are also provided with a rotating shaft, and the end of the rotating shaft is installed on the mixed garbage sorting machine housing. The claws of the sorting claws are driven by a motor, and pass through the comb-tooth groove of the support plate. The plurality of sorting claws are operated simultaneously to continuously move other garbage in the fallen garbage to the other side onto the conveyor belt of other garbage. During the moving process, the kitchen waste is divided and falls through the comb-tooth groove of the support plate.

[0040] A second kitchen waste bin 31 is disposed directly below the third sorting section 6 , a transfer belt 32 is disposed at the conveying end of the second sorting section 5 , and a plastic and bottle waste bin 33 is disposed at the conveying end of the first sorting section 4 .

[0041] After the kitchen waste has passed through three layers of filtration and falls, it will be collected by the corresponding second kitchen waste bin and disposed of uniformly. The first sorting section transports large pieces of garbage, generally some plastic bags, paper boxes, plastic bottles, etc., and corresponding plastic garbage bins are set up to receive and collect them. At the end of the second sorting section is a transfer belt, which is set at the same height as the third sorting section and is used to receive the garbage from the second sorting section, generally the discarded scraps of paper and other relatively small garbage. After being received by the transfer belt, it is transferred to the rotating conveyor belt for other garbage. Then, the hazardous garbage and kitchen waste are sorted out by Raman spectroscopy and mechanical claws and put into the corresponding garbage bins, and the remaining other garbage is pushed into the garbage bin through the push plate.

[0042] like Figure 1 As shown: the conveying end of the conveyor belt 32 is inside the housing 1, and the lower side of the housing 1 corresponding to the conveyor belt 32 is supported by a circulating conveyor belt 8, and the upper side of the conveyor belt 8 is provided with a push plate 81 corresponding to the position of other trash cans 12. The conveyor belt is higher than the height of all trash cans in the housing, and when the garbage on the conveyor belt moves to the top of other trash cans, the garbage is pushed into and falls into other trash cans by the push plate, wherein the push plate can be driven by an electric cylinder.

[0043] like Figure 1 As shown: a gantry 7 is provided on the upper side of the housing 1, and the gantry 7 is provided with a freely movable mechanical claw 71, and a Raman spectrometer 72 is also provided at the conveying end of the conveyor belt 32. When light is irradiated onto a substance, elastic scattering and inelastic scattering occur. The scattered light of elastic scattering has components with the same wavelength as the excitation light, and the scattered light of inelastic scattering has components with longer and shorter wavelengths than the excitation light, which are collectively referred to as the Raman effect. The composition of a material can be identified by the working principle of Raman spectroscopy, and the Raman spectrometer made according to the working principle of Raman spectroscopy is mainly used to identify the type of garbage, and then the harmful garbage or the garbage that needs to be finely classified is picked out by a robot.

[0044] like Figure 1 As shown: a baffle 82 is provided at the end of the transfer belt 32 to peel off the garbage attached to the transfer belt.

[0045] like Figure 3 As shown: arc-shaped baffles 62 are arranged on both sides of the third sorting section 6, and a guide plate 44 is arranged between the conveying end of the first sorting section 4 and the plastic and bottle trash can 33. The baffles and the guide plate are used to prevent garbage residues from falling into the gap between the trash can and the shell.

[0046] like Figure 1 As shown: the bottom of the shell 1 is provided with a tray 19 for placing other garbage bins 12, recyclable garbage bins 13 and the first kitchen waste bin 14, and the tray 19 is rotatable. The back side of the shell 1 corresponding to the garbage inlet 17 is provided with a door 16 for taking out the garbage bins. The tray is circular, and a driving device is provided at the bottom, which is rotatable; wherein, the other garbage bins are placed on the tray in groups of four, and the first kitchen waste bin and the recyclable garbage bin are placed in groups of two on another tray. Since the amount of other garbage is large, there are also many corresponding garbage bins. When it is automatically detected that the garbage bin on the side facing the garbage inlet is full, the turntable will automatically start to rotate to rotate the garbage bin to the back side, and the garbage bin will be taken out through the door.

[0047] like Figure 1 As shown: a guide channel 18 is provided between the garbage inlet 17 and the corresponding garbage bin, which is used to smoothly receive the garbage and guide it into the garbage bin.

[0048] like Figure 3 As shown: the bag breaking device 2 comprises a guide plate 23, a rotating first hook 24 is arranged above the guide plate 23, the guide plate 23 is provided with a plurality of parallel strip grooves, and circular blades 25 are installed in the strip grooves. The circular blades are fixedly installed on the rotating shaft, and the rotating shaft drives the plurality of circular blades to rotate at the same time, wherein the guide plate is installed with a pressure weighing sensor as a switch for sensing and starting the circular blades and the first hook. When the garbage is put in, the pressure weighing sensor is sensed and the first hook and the circular blade are started to rotate. The first hook hooks up the bag of garbage and cuts it through the circular knife on the lower side, and the garbage falls down.

[0049] like Figure 3 As shown: a second reverse hook 26 is also provided on the oblique upper side of the first hook 24, the second reverse hook 26 is staggered with the first hook 24, a slide plate 27 is provided directly below the second reverse hook 26, and a garbage bag bin 28 is provided at the corresponding end of the slide plate 27.

[0050] The first hook and the second reverse hook rotate in opposite directions. The second reverse hook is mainly used to remove the plastic bag on the first hook and guide the plastic bag into the garbage bag bin.
