Description

Technical Field

[0001] The present invention relates to the field of rail garbage transportation, and in particular to an intelligent garbage bin system. Background Art

[0002] As living standards improve, people's demands for hygienic living environments are becoming increasingly stringent, leading major cities and communities to increase their investment in sanitation. Garbage is solid waste generated in daily life and production. Due to its large volume, complex and diverse composition, and polluting properties, if not properly handled, it pollutes the environment, impacts sanitation, wastes resources, and undermines social harmony. Garbage disposal is a major issue affecting both the national economy and people's livelihoods. From residents' trash bins to final disposal plants, garbage undergoes a collection and distribution process. Enabling environmentally friendly, efficient, and intelligent automated transfer is a pressing challenge. The current community garbage collection and transportation process involves residents picking up garbage or community sanitation workers collecting it from high-rise buildings into community bins. The garbage is then transferred to fixed collection bins on the streets outside the community. Sanitation workers then transport it to a garbage transfer station using garbage trucks. After compacting the garbage at the transfer station, garbage trucks transport it to a waste treatment plant for final disposal. Many links in the garbage transfer process are still completed manually, requiring a lot of manpower, with a low degree of automation and low efficiency. Under this collection and transportation method, since the collection and transportation are carried out according to a set time, a set location, and a plan, and the collection garbage bins and garbage transfer stations are all set up on the ground, occupying a large area and the environment is not closed, frequent transfers or untimely transfers will cause environmental pollution problems, forming common urban phenomena such as dirt, disorder, poor quality, and smell.

[0003] To this end, the present invention provides a fully automatic, intelligent, and mechanized innovative garbage collection and transportation technology solution, which transports domestic garbage directly from residents' homes to garbage treatment plants, cutting out many intermediate transfer links, saving costs, being highly efficient, and being super environmentally friendly.

DETAILED DESCRIPTION

[0036] The present invention will be further described in detail below with reference to the examples, but the embodiments of the present invention are not limited thereto.

[0037] Example

[0038] like Figures 1 to 15 As shown, the present invention provides an intelligent trash can system comprising a six-way track 1 and N track trash cans mounted on the six-way track 1 via a running wheel train 2, where N ≥ 1 and the number of track trash cans can be set according to actual needs. All track trash cans can be moved along the six-way track 1 via the running wheel train 2.

[0039] like Figures 1 to 4 As shown, the rail trash can includes a small rail trash can bucket 3 and a large rail trash can bucket 5. The upper ends of the small rail trash can bucket 3 and the large rail trash can bucket 5 are both installed with a running wheel train 2, and the small rail trash can bucket 3 and the large rail trash can bucket 5 are both installed on the six-way track 1 through the running wheel train 2 and move along the six-way track 1 through the running wheel train 2.

[0040] The six-way track 1 has two track cavities and is spliced by several horizontal straight tracks, horizontal curved tracks, vertical curved tracks, and vertical straight tracks. The small track trash can 3 and the large track trash can 5 can freely move along the six-way track 1 in a straddling or hanging upside-down manner. The six-way track 1 is a prior art and has been disclosed in the invention patent with the application number CN202010989846.8, and will not be elaborated here. The six-way track 1 is fixed to the outer wall of the building in a bow-shaped steel structure and extends into the indoor of the household, so that the small track trash can 3 can drive into the indoor of the household in a straddling manner, facilitating the household to throw garbage into the small track trash can 3. The small track trash can 3 can be set in multiple numbers, so that garbage can be collected from multiple households at the same time. In addition, the small track trash can 3 can move above the large track trash can 5, and the small track trash can 3 can pour the garbage in it into the large track trash can 5. The garbage is uniformly collected in the large track trash can 5. At this time, the traveling wheel systems 2 on the small track trash can 3 and the traveling wheel systems 2 on the large track trash can 5 are located in different track cavities respectively. The traveling wheel system 2 is used to enable the small track trash can 3 and the large track trash can 5 to travel on the six-way track 1. It includes a wheel system bracket and two derailment devices respectively arranged on both sides of the wheel system bracket, etc. Since the traveling wheel system 2 is a prior art and has been disclosed in the invention patents with the application numbers CN202010987844.5 and CN202010989828.X, no further description will be given here.

[0041] As Figure 12 , 13 shown, a garbage disposal opening 13 is provided at the bottom of the small track trash can 3. Track trash can small track rails 14 are provided on the opposite side walls of the garbage disposal opening 13, and a closing mechanism is installed on the track trash can small track rails 14. The garbage disposal opening 13 is opened along the length direction of the small track trash can 3, and the closing mechanism is used to close the garbage disposal opening 13.

[0042] The number of the closing mechanisms is 2. The closing mechanism includes a track trash can small door 6 installed on the track trash can small track rail 14, a track trash can small motor 15 installed on the inner wall of the small track trash can 3, a track trash can small gear 16 installed on the main shaft of the track trash can small motor 15, and a track trash can small door rack provided on the lower surface of the track trash can small door 6 and meshing with the track trash can small gear 16; the track trash can small door 6 can slide along the track trash can small track rail 14, and when the track trash can small doors 6 of the two closing mechanisms move, they can open and close the garbage disposal opening 13.

[0043] During operation, as Figure 14As shown, the small bucket 3 of the orbital trash can enters the room along the six-way track 1 in a straddling or inverted hanging manner. The motor 15 of the small bucket of the orbital trash can drives the gear 16 of the small bucket of the orbital trash can to rotate. Through the rack of the door of the small bucket of the orbital trash can, two doors 6 of the small bucket of the orbital trash can can be driven to move to both sides, thus opening the trash disposal opening 13. The household can then throw the trash into the small bucket 3 of the orbital trash can. The motor 15 of the small bucket of the orbital trash can rotates in the reverse direction to close the trash disposal opening 13.

[0044] As Figure 5 , 6 shown, a trash collection opening 4 is provided at the top of the large bucket 5 of the orbital trash can. Rail trash can large bucket slide rails are provided on the opposite side walls of the trash collection opening 4. A lower door 8 is installed on the rail trash can large bucket slide rail. An upper door 10 is installed on the lower door 8 through a support slide rail 9. Driving mechanisms are connected to both the lower door 8 and the upper door 10.

[0045] Specifically, the driving mechanism includes a rail trash can large bucket motor 12 installed on the large bucket 5 of the orbital trash can, a rail trash can large bucket gear 11 installed on the rail trash can large bucket motor 12, and a rail trash can large bucket door rack 7 meshing with the rail trash can large bucket gear 11. The rail trash can large bucket door racks 7 of the two driving mechanisms are respectively installed on the lower door 8 and the upper door 10.

[0046] When it is necessary to pour the trash in the small bucket 3 of the orbital trash can into the large bucket 5 of the orbital trash can, the small bucket 3 of the orbital trash can is controlled to move above the large bucket 5 of the orbital trash can. The rail trash can large bucket motor 12 is started to drive the rail trash can large bucket gear 11 to rotate, and the lower door 8 or the upper door 10 is driven to move through the rail trash can large bucket door rack 7 to open the trash collection opening 4. After the trash collection opening 4 is opened, the trash disposal opening 13 is controlled to open, and the trash in the small bucket 3 of the orbital trash can then falls into the large bucket 5 of the orbital trash can to complete trash collection.

[0047] As Figures 7 to 11 shown, the bottom of the large bucket 5 of the orbital trash can is installed with a large bucket bottom door 26 through a door shaft 30, and a bottom door control mechanism connected to the large bucket bottom door 26. The large bucket bottom door 26 can be turned over around the door shaft 30. When the large bucket bottom door 26 is turned downwards, the trash in the large bucket 5 of the orbital trash can can be poured out.

[0048] The bottom door control mechanism includes two bottom door driving mechanisms respectively provided on both sides of the large bucket 5 of the orbital trash can, a sprocket motor 17 provided on the large bucket 5 of the orbital trash can, and a driving double gear 27 installed on the main shaft of the sprocket motor 17. The driving double gear 27 is respectively connected to the two bottom door driving mechanisms through a chain 18.

[0049] The bottom door drive mechanism includes a screw 19 disposed on the large bucket 5 of the rail trash can and capable of rotating, a screw-driven double gear 33 installed at the end of the screw 19, a nut 20 installed on the screw 19, a nut gear 25 connected to the nut 20, a bottom door rack 29 disposed on the lower surface of the large bucket bottom door 26 and meshing with the nut gear 25, a driven double gear 28 installed on the large bucket 5 of the rail trash can, an auxiliary gear 31 connected to the driven double gear 28, and an outer shaft gear 32 installed on the door shaft 30.

[0050] Specifically, a notch is provided on the large bucket bottom door 26 to facilitate the rotation of the outer shaft gear 32. When the outer shaft gear 32 rotates, it drives the door shaft 30 to rotate, thereby providing the driving force for the large bucket bottom door 26 to flip. In addition, one gear of the driven double gear 28 is connected to the screw-driven double gear 33 through a chain 18, and the other gear meshes with the auxiliary gear 31, while the auxiliary gear 31 meshes with the outer shaft gear 32. The screw 19 can be installed in a jacket, and the jacket can fix the nut 20 so that the nut 20 cannot rotate with the screw 19 and can only move back and forth along the screw 19; a chute can be provided on the jacket to facilitate the connection between the nut 20 and the nut gear 25.

[0051] When it is necessary to empty the garbage in the large bucket 5 of the rail trash can, the sprocket motor 17 is started, and the screw 19 is driven to rotate through the chain 18 and the screw-driven double gear 33. When the screw 19 rotates, the nut 20 moves along the screw 19, and the nut gear 25 moves along the bottom door rack 29; at the same time, when the screw 19 rotates, it drives the driven double gear 28 to rotate through the chain 18. When the driven double gear 28 rotates, it drives the auxiliary gear 31 to rotate, and the auxiliary gear 31 further drives the outer shaft gear 32 to rotate to further provide the driving force for the large bucket bottom door 26 to flip; when the nut gear 25 moves to the end of the screw 19, the large bucket bottom door 26 is opened, and the garbage in the large bucket 5 of the rail trash can is emptied. When the sprocket motor 17 rotates in reverse, the large bucket bottom door 26 can be closed.

[0052] A large bucket weighing device 24 can be provided on the large bucket bottom door 26, which is used to weigh the garbage in the large bucket 5 of the rail trash can. A small bucket weighing device 21 is provided at the top of the small bucket 3 of the rail trash can, which is used to weigh the garbage in the small bucket 3 of the rail trash can. When the weight of the garbage in the large bucket 5 or the small bucket 3 of the rail trash can reaches the set weight, it means that the garbage inside needs to be emptied.

[0053] A large bucket radar probe 23 is provided on the inner wall of the large bucket 5 of the rail trash can, and a small bucket radar probe 22 is provided on the inner wall of the small bucket 3 of the rail trash can. The radar probe can detect whether the garbage in the bucket reaches the warning height. If it does, it means that the garbage inside needs to be emptied. The present invention can be controlled by an external control system. Since the control system is not the inventive point of the present invention, the control system will not be described in detail here.

[0054] During operation, when a household needs to dispose of garbage, the control system makes the small bucket 3 of the rail trash can move forward along the six-direction rail 1 into the designated position inside the household, as Figure 14 shown. An RFID beacon can be set in the user's home. When the small bucket 3 of the rail trash can reaches the RFID beacon, the control system can identify the RFID beacon and control the small bucket 3 of the rail trash can to stop. At this time, the two small bucket motors 15 of the closing mechanism start to rotate forward, causing the small bucket gear 16 of the rail trash can to rotate. By controlling the two small bucket doors of the rail trash can to move to both sides, the garbage discharge opening 13 on the small bucket 3 of the rail trash can is opened. The household throws the garbage into the small bucket 3 of the rail trash can, and then controls the two small bucket motors 15 of the rail trash can to rotate in reverse, and the garbage discharge opening 13 is closed. When the garbage in the small bucket 3 of the rail trash can reaches a certain weight or is full, the small bucket 3 of the rail trash can exits the room along the six-direction rail 1 and is suspended upside down on the six-direction rail 1, and travels along the six-direction rail 1 to above the large bucket 5 of the rail trash can, as Figure 15 shown. The large bucket motor 12 of the rail trash can starts, driving the large bucket gear 11 of the rail trash can to rotate. Driven by the large bucket door rack 7 of the rail trash can, the lower door 8 or the upper door 10 moves to open the garbage collection port 4. The two small bucket motors 15 of the rail trash can start to rotate forward, causing the small bucket gear 16 of the rail trash can to rotate. By controlling the two small bucket doors 6 of the rail trash can to move to both sides, the garbage discharge opening 13 is opened again. At this time, the garbage in the small bucket 3 of the rail trash can falls into the large bucket 5 of the rail trash can, completing the unified collection of garbage. When the garbage in the large bucket 5 of the rail trash can is full, the large bucket 5 of the rail trash can is controlled to travel to the garbage collection pool of the garbage treatment plant. An RFID beacon can also be set at the garbage collection pool of the garbage treatment plant. When the large bucket 5 of the rail trash can reaches the RFID beacon, the garbage in the large bucket 5 of the rail trash can is emptied.
