Description

Technical Field

[0001] This utility model relates to the technical field of waste sorting and recycling, specifically to an automatic bin-changing device. Background Technology

[0002] Waste sorting refers to the process of classifying daily waste into different categories according to certain regulations or standards for collection, storage, transportation, and treatment. The aim is to improve waste disposal efficiency, reduce environmental pollution, and promote resource recycling. Current waste sorting methods typically include setting up separate waste bins at residential areas and unified sorting at treatment plants. Setting up separate waste bins at residential areas, along with publicizing waste sorting to residents, encourages them to voluntarily sort their waste and dispose of it in the corresponding bins; this method is more convenient. Traditional waste collection involves placing one bin for each category at a designated waste sorting and collection point, and then having garbage trucks collect the waste at set times.

[0003] Currently, most automatic bin-changing devices typically use two conveyor belts to transport trash cans, one above the other. An automatic changing mechanism then transfers the trash cans from the upper conveyor belt to the lower one. However, the upper conveyor belt lacks a guiding mechanism, which leads to the following drawbacks: trash cans may shift or become misaligned during transport, preventing them from accurately engaging with the subsequent automatic changing mechanism. This can cause equipment malfunctions or operational errors, ultimately preventing the entire device from functioning properly. Utility Model Content

[0004] The purpose of this invention is to provide an automatic bin-changing device to solve the problem that when trash cans are transported on the conveyor belt above, they may shift or become misaligned, making it impossible for the trash cans to accurately connect with the subsequent automatic changing mechanism, which in turn causes equipment failure or operational errors, resulting in the entire device failing to operate normally.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an automatic bin-changing device, including a panel, the panel being fixed to the rear side of the outer wall of a placement rack, the placement rack having a placement position, the placement rack having two conveyor belts inside, the upper conveyor belt having several trash cans, a dispensing port being opened on one side of the panel, fixing plates being fixed to the left and right sides of the placement rack, electric push rods being fixed to the outer sides of the two fixing plates, one end of the telescopic rods of the two electric push rods passing through the two fixing plates and respectively fixing a U-shaped frame, guide wheels being rotatably provided inside the two U-shaped frames, and an automatic changing mechanism being provided on the placement rack.

[0006] Preferably, the automatic replacement mechanism includes a PLC controller, which is fixed to the right side of the outer wall of the placement rack. The PLC controller is electrically connected to the conveyor belt. A weight sensor is provided at the placement position, and the weight sensor is electrically connected to the PLC controller. Several trash cans have downward-facing hanging ears on their upper side walls, and the hanging ear openings are V-shaped. Synchronous belts are provided on the left and right sides of the outer wall of the placement rack, and conveyor chains are provided on the left and right sides of the inner wall of the placement rack. Bolts are used to connect the conveyor chains to horizontal support rods that run between the placement racks. The conveyor track of the conveyor chain is a right-angled inverted trapezoid, and the straight side of the conveyor track is perpendicular to the placement position. The panel is parallel to and aligned with the center of the placement position. The top bearing of the placement rack is connected to a drive shaft located between the placement racks. The drive shaft is connected to a drive motor, which is bolted to the placement rack. Both ends of the drive shaft are driven by the drive shafts of two conveyor chains via synchronous belts. The bottom edge of the conveyor track is located below the hanging ear at the placement position and extends laterally to the outside of the placement position. The vertical distance between the bottom edge of the conveyor track and the lower conveyor belt is less than the height of the hanging ear. The top edge of the conveyor track is located above the upper conveyor belt and extends laterally to the upper hanging ear of the first trash can at the front end of the upper conveyor belt.

[0007] Preferably, a fixing hole is provided on one side of the panel, and a voice broadcaster is fixed inside the fixing hole. The voice broadcaster is electrically connected to the PLC controller.

[0008] Preferably, the inside of the dispensing port is rotatably equipped with a baffle.

[0009] Preferably, a first rubber pad is fixed to the bottom end of the baffle, and a second rubber pad is fixed to the bottom surface of the dispensing port.

[0010] Preferably, an ultraviolet germicidal lamp is fixed to the front side of the panel, and the ultraviolet germicidal lamp is located at the bottom near the inlet.

[0011] Compared with existing technologies, an automatic drum changing device that adopts the above technical solution has the following advantages:

[0012] 1. In use, the coordinated use of the panel, placement rack, conveyor belt, fixing plate, electric push rod, U-shaped frame and guide wheels facilitates the transportation of garbage bins. At the same time, it ensures that the garbage bins are always in the center position during transportation, effectively avoiding the displacement or misalignment of garbage bins during transportation. This not only ensures that the garbage bins can accurately dock with the subsequent automatic replacement mechanism, but also improves the stability and reliability of the device operation, reduces equipment failures and operational errors caused by garbage bin misalignment, and ensures that the entire device can operate normally.

[0013] II. In operation, the straight edge of the conveyor track is parallel to the panel and aligned with the center of the placement position, ensuring the support rod accurately transports the trash can to the placement position. The support rod is smaller than the hanging ears so that after transporting the trash can to the placement position, it can automatically detach from the hanging ears during its continued movement, avoiding interference with the trash can. The upper bottom edge of the conveyor track is located above the upper conveyor belt and extends laterally to above the hanging ear of the first trash can at the front end of the upper conveyor belt. This allows the support rod, after detaching from the hanging ears, to continue moving upwards along the conveyor track and enter the hanging ear of the first trash can at the front end of the upper conveyor belt. The automated process completes the bin changing, moving the full trash can to the rear end of the lower conveyor belt for temporary storage, awaiting periodic collection and cleaning by the garbage truck.

[0014] Thirdly, during use, after the weight sensor completes the weighing operation, it quickly transmits the relevant information to the PLC controller. After analysis and judgment, the PLC controller determines that the trash can needs to be replaced and immediately activates the voice broadcaster. The voice broadcaster then issues a clear and unambiguous voice reminder, informing residents that the trash can replacement is in progress and preventing them from disposing of trash at the wrong time. The baffle automatically resets under its own weight, blocking the disposal opening again, effectively reducing the emission of odors from the trash can into the surrounding environment. The combined use of the first and second rubber pads helps reduce the impact on hands, preventing residents' hands from being pinched when the baffle resets. Ultraviolet germicidal lamps irradiate the opening of the trash can in its placement position, reducing odors and bacterial growth. Attached Figure Description

[0020] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown, an automatic bin-changing device includes a panel 1, which is fixed to the rear side of the outer wall of a placement rack 2. The placement rack 2 has a placement position 3, and two conveyor belts 4 are provided inside the placement rack 2. Several trash cans 5 are placed on the upper conveyor belt 4. A disposal port 6 is opened on one side of the panel 1. Fixing plates 7 are fixed to the left and right sides of the placement rack 2, and electric push rods 8 are fixed to the outer sides of the two fixing plates 7. One end of the telescopic rod of the two electric push rods 8 passes through the two fixing plates 7 and is fixed with a U-shaped frame 9. Guide wheels 10 are rotatably provided inside the two U-shaped frames 9. An automatic changing mechanism is provided on the placement rack 2.

[0022] In use, staff deploy the device at the garbage sorting and recycling points in residential areas. Multiple sets can be placed simultaneously according to garbage sorting needs. Initially, four to five empty garbage bins 5 are placed side by side on the conveyor belt 4 above each set. One empty garbage bin 5 is placed at the placement position 3. When in use, residents put garbage into the garbage bin 5 through the disposal port 6. When the garbage bin 5 is to be replaced, two electric push rods 8 are activated to bring two U-shaped frames 9 closer together. This allows several guide wheels 10 inside the two U-shaped frames 9 to contact the left and right sides of the outer walls of several garbage bins 5 on the upper conveyor belt 4. When the upper conveyor belt 4 transports the garbage bins 5, the guide wheels 10 guide the garbage bins 5, ensuring that the garbage bins 5 are always transported in the middle position of the upper conveyor belt 4, so that the garbage bins 5 are accurately aligned with the subsequent automatic replacement mechanism. The coordinated use of panel 1, placement rack 2, conveyor belt 4, fixing plate 7, electric push rod 8, U-shaped frame 9, and guide wheel 10 facilitates the transportation of trash can 5 and ensures that trash can 5 remains in the center position during transportation. This effectively prevents trash can 5 from shifting or becoming misaligned during transportation, ensuring that trash can 5 can accurately connect with the subsequent automatic replacement mechanism, improving the stability and reliability of the device, reducing equipment failures and operational errors caused by misalignment of trash can 5, and ensuring the normal operation of the entire device.

[0023] like Figure 1 , Figure 2 and Figure 4As shown, the automatic replacement mechanism includes a PLC controller 11, which is a Siemens S7-200. The PLC controller 11 is fixed to the right side of the outer wall of the placement rack 2 and is electrically connected to the conveyor belt 4. A weight sensor 12 is provided at the placement position 3 and is electrically connected to the PLC controller 11. Several trash cans 5 have downward-facing hanging ears 13 on their upper side walls, with V-shaped openings. Synchronous belts 14 are provided on the left and right sides of the outer wall of the placement rack 2, and conveyor chains 15 are provided on the left and right sides of the inner wall of the placement rack 2. Bolted to the conveyor chains 15 are support rods 17 that laterally face the placement racks 2. The conveying trajectory of the conveyor chains 15 is perpendicular to the ground. The trapezoidal conveyor track has its straight waist side parallel to the panel 1 and aligned with the center of the placement position 3. The top bearing of the placement rack 2 is connected to a drive shaft 16 located between the placement racks 2. The drive shaft 16 is connected to a drive motor, which is bolted to the placement rack 2. The two ends of the drive shaft 16 are driven by the drive shafts of the two conveyor chains 15 via a synchronous belt 14. The bottom edge of the conveyor track is located below the hanging ear 13 at the placement position 3 and extends laterally to the outside of the placement position 3. The vertical distance between the bottom edge of the conveyor track of the conveyor chain 15 and the lower conveyor belt 4 is less than the height of the hanging ear 13. The top edge of the conveyor track is located above the upper conveyor belt 4 and extends laterally to the upper part of the hanging ear 13 of the first trash can 5 at the front end of the upper conveyor belt 4.

[0024] In use, the straight waist edge of the conveyor track is parallel to the panel 1 and aligned with the center of the placement position 3, so that the support rod 17 can accurately transport the trash can 5 to the placement position 3. The support rod 17 is smaller than the hanging ear 13 so that after transporting the trash can 5 to the placement position 3, it can separate from the hanging ear 13 on its own during the continued movement and avoid interfering with the trash can 5. The upper bottom edge of the conveyor track is located above the upper conveyor belt 4 and extends laterally to the upper hanging ear 13 of the first trash can 5 at the front end of the upper conveyor belt 4, so that after separating from the hanging ear 13, the support rod 17 can enter the hanging ear 13 of the first trash can 5 at the front end of the upper conveyor belt 4 along the conveyor track during the continued operation.

[0025] During continuous garbage disposal, the weight sensor 12 monitors the weight of the collected garbage. Once the preset weight is reached, the weight information is fed back to the PLC controller 11. The PLC controller 11 outputs an action signal to the drive motors of the upper conveyor belt 4, the lower conveyor belt 4, and the conveyor chain 15, causing the lower conveyor belt 4 to start and move the full garbage bin 5 backward a certain distance away from the placement position 3 before stopping. The conveyor chain 15, through the cooperation of the support rod 17 and the hanging ear 13, lifts the first empty garbage bin 5 at the front end of the upper conveyor belt 4, and then moves it horizontally and lowers it. The trash cans are transported to placement position 3. Then, the conveyor chain 15 continues to run, causing the support rod 17 to move downwards and disengage from the hanging ear 13. After that, the support rod 17 moves horizontally and upwards to disengage from placement position 3 and then stops. The upper conveyor belt 4 runs and transports all the empty trash cans 5 forward by the distance of one trash can 5 before stopping. This allows the support rod 17 on the conveyor chain 15 to move again and insert into the hanging ear 13 of the first trash can 5 at the front end of the upper conveyor belt 4. In this way, the trash can is changed automatically, and the trash can 5 filled with trash is moved to the rear end of the lower conveyor belt 4 for temporary storage, waiting for the garbage truck to collect and clean it regularly.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a fixing hole 18 is provided on one side of the panel 1, and a voice broadcaster 19 is fixed inside the fixing hole 18. The voice broadcaster 19 is electrically connected to the PLC controller 11, and a baffle 20 is rotatably provided inside the dispensing port 6.

[0027] During use, after the weight sensor 12 completes the weighing operation, it quickly transmits the relevant information to the PLC controller 11. After analysis and judgment, the PLC controller 11 determines that the trash can 5 needs to be replaced and immediately activates the voice announcer 19. The voice announcer 19 then issues a clear and unambiguous voice reminder, informing residents that the trash can 5 is being replaced, preventing them from disposing of trash at the wrong time. When residents need to dispose of trash, they simply need to gently push the rotatable baffle 20 inside the disposal opening 6 to put the trash into the trash can 5. After disposal, the baffle 20 automatically resets under its own weight, blocking the disposal opening 6 again, effectively reducing the odor from the trash can 5 from escaping into the surrounding environment.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a first rubber pad 21 is fixed to the bottom of the baffle 20, a second rubber pad 22 is fixed to the bottom of the inlet 6, and an ultraviolet germicidal lamp 23 is fixed to the front side of the panel 1. The ultraviolet germicidal lamp 23 is located at the bottom near the inlet 6.

[0029] During use, the combined use of the first rubber pad 21 and the second rubber pad 22 helps to reduce the impact of the baffle 20 on the hands, preventing residents' hands from being pinched when the baffle 20 resets. The ultraviolet germicidal lamp 23 irradiates the opening of the garbage can 5 in the placement position 3, reducing odors and bacterial growth.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
