Description

Technical Field

[0001] This invention belongs to the technical field of environmental protection equipment, specifically relating to a waste sorting device with a quick-opening and closing door and its usage method. Background Technology

[0002] Trash cans are one of the most widely used environmental protection devices in society today. Their widespread use has not only improved people's quality of life but also reduced urban environmental pollution.

[0003] With social development, waste sorting bins have gradually appeared on the market. However, the existing sorting bins are relatively complex in structure and their sorting effect is not ideal. The specific shortcomings are as follows:

[0004] 1. After the garbage is identified, the classified garbage bins need to be flipped into the corresponding garbage bins. In order to prevent garbage from being thrown in during the flipping process, a closed door needs to be installed at the garbage inlet. Therefore, the existing classified garbage bins have a drive structure for the garbage flipping structure and a sealing structure for the closed door. This makes the classified garbage bins complex in structure and costly.

[0005] 2. Existing waste sorting and identification systems typically only collect images of waste to identify its type. However, in some cases, images alone are insufficient for accurate identification. For example, if a piece of paper with a picture of fruit is placed in the sorting device, the visual recognition system may mistake the picture for real fruit, thus classifying the paper as food waste and placing it in the food waste bin. The best solution is to add detection dimensions, using multiple dimensions to comprehensively determine the specific type of waste. This would significantly increase the likelihood of the software correctly identifying the waste type. Currently, no multi-dimensional waste identification bins have been implemented.

[0006] 3. In actual use, it was found that some garbage had water seeping out, which caused paper to stick to the rotating plate and become impossible to pour out. Sometimes other garbage also stuck to the rotating plate. This garbage affected the normal use of the rotating plate. A cleaning device needs to be designed to remove the garbage stuck to the rotating plate without affecting garbage sorting. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to address the shortcomings of the prior art by providing a waste sorting device with a quick-opening and closing door and a method for using it.

[0008] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0009] A waste sorting device with a quick-opening and closing door includes a waste bin body. A waste inlet is located on the upper front side of the waste bin body. Two waste bins are placed inside the lower part of the waste bin body. A four-part tilting device is installed inside the upper part of the waste bin body. The four-part tilting device includes a tilting frame, a four-part tilting disc, and a drive structure. The tilting frame is connected to the waste bin body, and the four-part tilting disc is rotatably mounted on the tilting frame. The four-part tilting disc includes a shaft, and four structural parts are fixed around the shaft: an upper hopper structure, a lower hopper structure, a left shield, and a right shield. The shaft is connected to the drive structure, which drives the shaft to rotate, thereby causing the upper hopper structure, lower hopper structure, left shield, and right shield to rotate inside the upper part of the waste bin body. As the shaft rotates, only one of the upper hopper structure, lower hopper structure, left shield, and right shield can open and close simultaneously. The structure can be aligned with the garbage inlet. When the upper or lower hopper structure is aligned with the garbage inlet, garbage can be fed into the upper or lower hopper structure from the garbage inlet. When the left or right blocking part is aligned with the garbage inlet, the left or right blocking part blocks the garbage inlet, thus closing the garbage inlet. At the same time, the upper or lower hopper structure pours garbage into the garbage bin as the disc rotates. A garbage sorting detector is installed inside the garbage bin body. The garbage sorting detector can collect garbage information. The garbage sorting device also includes a cloud controller. The garbage sorting detector is connected to the cloud controller. The cloud controller receives and analyzes the garbage information sent by the garbage sorting detector and makes a judgment on the type of garbage. The cloud controller is connected to the drive structure. The cloud controller can send control signals to the drive structure, causing the drive structure to control the four-part rotating disc to rotate clockwise or counterclockwise.

[0010] To optimize the above technical solution, the specific measures also include:

[0011] The four-part rotating disc includes a rear circular plate, four receiving plates, and two shielding plates. The rear circular plate is fixed to the rear end of the disc shaft and is concentric with the disc shaft. The front end of the disc shaft is at the position corresponding to the rear circular plate. The four receiving plates form an "X" shape and are fixed between the front notch and the rear circular plate. The inner end of the receiving plates is fixed to the disc shaft, and the outer end is flush with the outer edge of the rear circular plate. The two shielding plates are fixed to the end of the disc shaft near the garbage inlet. The longitudinal section of the shielding plates can cover the garbage inlet. The shielding plates are arranged on the left and right sides. The right end of the left shielding plate is fixedly connected to the disc shaft, and the left end of the right shielding plate is fixedly connected to the disc shaft. The upper part of the front notch, the upper part of the rear circular plate, and the two upper receiving plates together form the upper hopper structure. The lower part of the front notch, the lower part of the rear circular plate, and the two lower receiving plates together form the lower hopper structure. The left shielding plate and the disc shaft form the left shielding part, and the right shielding plate and the disc shaft form the right shielding part.

[0012] The trash cans are placed on the left and right sides at the bottom of the main body of the trash can. One trash can is for recyclable waste, and the other is for non-recyclable waste. When the four-part tilting plate rotates clockwise, the upper hopper structure tilts down and pours the trash into the trash can on the right. When the four-part tilting plate rotates counterclockwise, the upper hopper structure tilts down and pours the trash into the trash can on the left.

[0013] The top of the main body of the trash can is fixed inside the top of the main body frame, the tilting plate frame is hung on the top frame, and a weighing device is fixed at the connection between the tilting plate frame and the main body top frame. The weighing device is used to weigh the entire four-part tilting plate device. The weighing device is connected to the cloud controller, and the cloud controller receives and analyzes the weight information transmitted by the weighing device.

[0014] A camera is fixed on the rotating tray frame. The camera is used to capture images of the garbage in the upper or lower hopper structure when it is aligned with the garbage inlet. The camera is connected to the cloud controller, which receives and analyzes the image information transmitted from the camera. The weighing device and the camera together form a garbage sorting detector.

[0015] The main body of the trash can is located below the four-part tipping device and above the two trash cans, with a central frame. A blower is installed on the central frame, positioned between the two trash cans, with its opening facing upwards. When one hopper structure is aligned with the trash inlet, the blower can blow dry, hot gas into the other hopper structure, which is not aligned with the trash inlet. The blower is connected to a cloud controller, which controls the start and stop of the blower.

[0016] The drive structure includes a motor mounting bracket and a rotary motor. The motor mounting bracket is fixed on the tilting disc frame, and the rotary motor is fixed on the motor mounting bracket. The motor shaft of the rotary motor is fixedly connected to the disc shaft.

[0017] The front side of the trash can body has a cleaning door. When the cleaning door is opened, the trash can can be taken out from inside the trash can body through the cleaning door.

[0018] The shield is made of stainless steel.

[0019] A method for using a waste sorting device with a quick-opening and closing door, specifically including the following steps:

[0020] Assume the initial state is that the left shielding part is located at the top of the four-part tilting disc device, the right shielding part is located at the bottom of the four-part tilting disc device, the upper hopper structure is located at the right side of the four-part tilting disc device, the lower hopper structure is located at the left side of the four-part tilting disc device, and the hopper structure that received the waste in the previous instance is the lower hopper structure.

[0021] Step 1: Send a signal to the cloud controller. The cloud controller controls the rotary motor to rotate counterclockwise by a quarter turn, moving the left obstruction that was originally blocking the garbage inlet to the left side of the quarter-turn tilting device. The upper hopper structure moves to the top of the quarter-turn tilting device. At this point, the upper hopper structure is aligned with the garbage inlet.

[0022] Step 2: Dispose of the waste into the waste inlet. The waste is caught by the upper hopper structure. At this time, the total weight of the four-part tilting device rises, and the amount of rise is the weight of the waste. The weighing device sends the weight information to the cloud controller. The camera takes a picture of the waste in the upper hopper structure and sends the image of the waste to the cloud controller.

[0023] Step 3: The cloud controller's memory stores corresponding data on garbage images, garbage weights, and garbage types. The cloud controller compares the received garbage images and garbage weights with the data stored in the memory to obtain the type of garbage in the upper hopper structure. Based on the type of garbage, the cloud controller controls the rotation of the rotary motor to flip the upper hopper structure towards the corresponding garbage bin. While the upper hopper structure is located above the four-part flipping device, the blower blows air onto the lower hopper structure to remove residual garbage and water stains.

[0024] Step 4: Under the control of the cloud controller, the rotary motor rotates one-quarter revolution. At this time, the upper hopper structure turns horizontal, and the garbage is poured into the corresponding garbage bin. The left or right shielding part blocks the garbage feeding port. During the next garbage feeding, the lower hopper structure receives the garbage, and the upper hopper structure rotates further to the lower part of the quarter-turning disc device. The blower blows air onto the upper hopper structure.

[0025] Step 5: Repeat steps 1 to 4 until the trash can is overflowing. Open the trash can body and replace it with a new trash can.

[0026] The present invention has the following advantages:

[0027] This invention designs a four-part rotating disc, which includes two spaced-apart hopper structures and two shielding parts. By rotating, the hopper structures receive garbage and pour it into the corresponding garbage bins, while the shielding parts block the garbage inlet while the hopper structures are emptying the garbage. The hopper structures and shielding parts share a single disc shaft and drive structure, which effectively saves internal space in the garbage bin body.

[0028] The waste sorting device of this invention not only has a camera to capture images of waste, but also a weighing device to collect the weight of waste. The cloud controller's memory stores corresponding data of waste images, waste weights, and waste types in advance. The cloud controller compares the received waste images and waste weights with the data stored in the memory to obtain the waste type. This multi-dimensional method of collecting waste information and using this information to determine the waste type can effectively improve the accuracy of waste type determination compared to the method of determining waste type only by using images.

[0029] This invention incorporates a blower inside the main body of the trash can. The blower blows dry, hot gas, and after each time the hopper structure is tumbled, the blower dries the water inside and removes any remaining trash, which falls to the bottom of the main body for later cleaning. By using the blower, no trash remains in the hopper structure, allowing it to operate normally for extended periods. Attached Figure Description

[0042] The waste sorting device of the present invention, which features a quick-opening and closing door for sorting, mainly includes a waste bin body 1, a four-part flipping device 2, a waste bin 12, a waste sorting detector 3, a blower 15, and a cloud controller, among other main components.

[0043] The main body of the trash can 1 has a trash inlet 11 on the upper front side. Two trash cans 12 are placed inside the lower part of the main body 1: one for recyclable waste and the other for non-recyclable waste. In actual use, they can also be a general waste bin and a food waste bin. The main body 1 has frame structures at the top and middle. The top frame 13 is used to hang the four-part tipping device 2, and the middle frame 14 is used to install the blower 15.

[0044] The four-part tipping device 2 is the main innovative structure of this invention, comprising three parts: a tipping frame 21, a four-part tipping disc 22, and a drive structure 23. The four-part tipping device 2 is not fixedly connected to the main body 1 of the trash can; it is a separate device, suspended from the top frame 13 of the main body via the tipping frame 21, similar to a hanging basket. The mounting point is a weighing device 31, which can weigh the four-part tipping device 2 and thus calculate the weight of the trash placed on it.

[0045] The four-part rotating disc 22 includes a rear circular plate 22b, four receiving plates 22c, and two blocking plates 22d. The rear circular plate 22b is fixed to the rear end of the disc shaft 221 and is concentric with the disc shaft 221. The front end of the disc shaft 221 has a front notch 22a corresponding to the position of the rear circular plate 22b. The four receiving plates 22c are fixed in an "X" shape between the front notch 22a and the rear circular plate 22b. The inner end of the receiving plate 22c is fixed to the disc shaft 221, and the outer end is flush with the outer edge of the rear circular plate 22b. The two blocking plates 22d are both fixed to the end of the disc shaft 221 near the garbage inlet 11. The blocking plates 22d are parallel to the garbage inlet 11, and the distance between them is no more than 5mm. The blocking plates 22d can completely block the garbage inlet 11.

[0046] To facilitate the description of the positional relationships of the structures, this embodiment uses... Figure 5 As shown, the upper part of the front notch 22a, the upper part of the rear circular plate 22b, and the two upper receiving plates 22c together form the upper hopper structure 222. The lower part of the front notch 22a, the lower part of the rear circular plate 22b, and the two lower receiving plates 22c together form the lower hopper structure 223. The left blocking plate 22d and the disc shaft 221 form the left blocking part 224, and the right blocking plate 22d and the disc shaft 221 form the right blocking part 225. Therefore, the upper hopper structure 222 is located on the upper part of the quarter-turning disc device 2, the lower hopper structure 223 is located on the upper part of the quarter-turning disc device 2, the left blocking part 224 is located on the left side of the quarter-turning disc device 2, and the right blocking part 225 is located on the right side of the quarter-turning disc device 2. Once the quarter-turning disc device 2 rotates, the positions of each hopper structure and blocking part will change.

[0047] The waste sorting detector 3 includes a weighing device 31 and a camera 32. The weighing device 31 weighs the waste on the four-part tilting disc device 2. The camera 32 is fixed to the tilting disc frame 21 and is used to capture images of the waste in the hopper structure when it is aligned with the waste inlet 11.

[0048] Both the weighing device 31 and the camera 32 are connected to the cloud controller. The cloud controller is used to receive and analyze the garbage information sent by the weighing device 31 and the camera 32 to make a judgment on the type of garbage. The cloud controller is connected to the drive structure 23 by signal. The cloud controller can send control signals to the drive structure 23 to make the drive structure 23 control the four-part flip plate 22 to rotate clockwise or counterclockwise.

[0049] The drive structure 23 includes a motor mounting bracket 23a and a rotary motor 23b. The motor mounting bracket 23a is fixed on the tilting disc frame 21, and the rotary motor 23b is fixed on the motor mounting bracket 23a. The motor shaft of the rotary motor 23b is fixedly connected to the disc shaft 221.

[0050] A cleaning door 16 is provided on the front side of the trash can body 1. When the cleaning door 16 is opened, the trash can 12 can be taken out from the trash can body 1 through the cleaning door 16.

[0051] The main body of the trash can 1 draws power from the nearby power grid via electrical wires.

[0052] This invention discloses a method for using a waste sorting device with a quick-opening and closing door, comprising the following steps:

[0053] Assume the initial state is that the left blocking part 224 is located on the upper part of the four-part tilting device 2, the right blocking part 225 is located on the lower part of the four-part tilting device 2, the upper hopper structure 222 is located on the right side of the four-part tilting device 2, the lower hopper structure 223 is located on the left side of the four-part tilting device 2, the hopper structure that received the previous garbage is the lower hopper structure 223, the garbage bin 12 on the left is a recyclable garbage bin, and the garbage bin 12 on the right is a non-recyclable garbage bin.

[0054] Step 1: The user sends a signal to the cloud controller, which then controls the rotary motor 23b to rotate counterclockwise by a quarter turn. This moves the left obstruction 224, which was originally blocking the waste inlet 11, to the left side of the quarter-turning disc device 2, and the upper hopper structure 222 to the top of the quarter-turning disc device 2. At this point, the upper hopper structure 222 is aligned with the waste inlet 11, as shown in the image. Figure 3 As shown,

[0055] Step 2: The user throws garbage into the garbage inlet 11. The garbage is caught by the upper hopper structure 222. At this time, the total weight of the quarter-turning disc device 2 rises, and the amount of rise is the weight of the garbage. The weighing device 31 sends the weighed weight information to the cloud controller. The camera 32 takes a picture of the garbage in the upper hopper structure 222 and sends the garbage image to the cloud controller.

[0056] Step 3: The cloud controller's memory stores corresponding data on garbage images, garbage weights, and garbage types. The cloud controller compares the received garbage images and garbage weights with the data stored in the memory to obtain the type of garbage in the upper hopper structure 222. Based on the type of garbage, the cloud controller controls the direction of rotation of the rotary motor 23b. Assuming the cloud controller determines that the garbage is recyclable, the cloud controller controls the rotary motor 23b to rotate counterclockwise by a quarter turn, causing the upper hopper structure 222 to flip towards the recyclable garbage bin. While the upper hopper structure 222 is located above the quarter-turning disc device 2, the blower 15 blows air onto the lower hopper structure 223 to remove residual garbage and water stains from the lower hopper structure 223.

[0057] Step 4: After the rotary motor 23b rotates, the upper hopper structure 222 turns horizontal, and the garbage is poured into the recyclable waste bin. The right shield 225 blocks the garbage feeding port 11; thus completing this garbage sorting and recycling action.

[0058] Each time garbage is collected, the hopper structure should be staggered to receive the garbage. The purpose of this is to ensure that the hopper structure after receiving the garbage can be cleaned by the blower 15.

[0059] An infrared sensor is installed at trash can 12 to detect whether trash can 12 is overflowing. When trash can 12 is overflowing, staff will open the main body of trash can 1 and replace it with a new trash can 12.

[0060] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should be considered within the scope of protection of the present invention.
