Description

Technical Field

[0001] This invention relates to the field of waste sorting and recycling technology, and in particular to an automatic integrated machine for multi-bin waste sorting, collection, and compression. Background Technology

[0002] Currently, although waste sorting and recycling have been carried out for many years, existing trash cans usually only provide simple sorting and disposal functions, relying on multiple independent trash cans to collect different types of waste, and lacking corresponding dedicated trash cans to realize waste collection management.

[0003] Because various types of recyclable waste are bulky and loose, they quickly fill the space inside the trash can when directly put in, resulting in the actual filling capacity of the trash can being far less than its theoretical volume, requiring frequent collection and emptying. Although some trash cans now have compression functions, after the waste is compressed, it adheres tightly to the can wall, making it difficult for workers to lift the heavy trash bags out of the can during collection. Furthermore, the trash bags are prone to tearing and waste scattering during the collection process. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides an automatic integrated machine for multi-bin collection and compression of waste sorting, comprising: a frame, with multiple first waste bins symmetrically arranged circumferentially within the frame, each first waste bin having a through-hole hollow cylindrical structure, and each first waste bin containing a waste bag; the frame having a first waste inlet for discharging waste and a lower door for retrieving waste, the positions of the first waste bins matching the positions of the first waste inlet, and the lower door correspondingly positioned below the first waste inlet; a compression unit within the frame, comprising a rotating mechanism, a compression mechanism, and a distance sensor, the distance sensor being positioned above the first waste bins for detecting the height of the waste stacking within the first waste bins; the rotating mechanism being located at the axis of the frame, and the compression mechanism being mounted on the rotating mechanism, rotating under the drive of the rotating mechanism to above the first waste bins to compress the waste within the first waste bins; and a lifting unit outside the first waste bins for raising and lowering them, the lifting unit lifting the first waste bins while the compression mechanism compresses the waste within, thus expelling the packaged waste from the first waste bins.

[0005] Specifically, the frame is cylindrical in shape and includes an upper door and a support frame. The upper door contains a bottom plate, a mounting plate, and a top plate.

[0006] Specifically, the compression mechanism includes a crossbeam arranged radially on the rotating mechanism, and two compression cylinders are arranged below both sides of the crossbeam corresponding to the positions of the first trash can. The piston rods of the compression cylinders are provided with pressure plates at their ends.

[0007] Specifically, a roller is provided above the first trash can in the support frame, and locking cylinders are provided at opposite ends of the crossbeam. A locking block is installed at the end of the piston rod of the locking cylinder, and a limit groove is provided at the end of the crossbeam. The locking block is slidably installed in the limit groove, the piston rods of the two locking cylinders are arranged in opposite directions, and the upper surface of the locking block is not lower than the lower surface of the roller.

[0008] Specifically, a fan-shaped bracket is fixedly installed on the lower side of the crossbeam, and the distance sensor is set on the lower side of the bracket. The controller is electrically connected to the distance sensor and the compression cylinder. Based on the stacking height of the garbage in the first garbage bin collected at a preset frequency, the controller controls the compression unit to rotate to the top of the corresponding first garbage bin, so that the piston rod of the compression cylinder extends and compresses the garbage in the bin.

[0009] Specifically, the lifting unit includes at least two lead screws arranged parallel to each other on both sides of the first trash can. The two ends of the lead screws are respectively rotatably connected between the base plate and the mounting plate of the frame. A guide rod is arranged parallel to the lead screw. A support plate for supporting the first trash can is provided on the lead screw and the guide rod. The lead screw is connected by a chain drive mechanism.

[0010] Specifically, the chain drive mechanism includes a lifting motor located on the side of the first trash can near the axis. The output end of the lifting motor is equipped with a drive wheel, and four transmission wheels are arranged around the circumference of the first trash can. The transmission wheels include two first transmission wheels symmetrically arranged on the left and right sides of the first trash can and two second transmission wheels symmetrically arranged on the front side of the first trash can. The first transmission wheels are fixedly installed on the upper end of the lead screw, and the drive wheel and the transmission wheels are connected by a chain drive.

[0011] Specifically, a pressure ring is fitted on the upper side of the first trash can, the lower end of the pressure ring is fitted inside the first trash can, the upper end of the pressure ring is funnel-shaped, the trash bag is fitted inside the first trash can, and its upper opening clamps and fixes the first trash can and the pressure ring, and the length of the trash bag is longer than the height of the first trash can.

[0012] Specifically, the bottom aperture of the first trash can is larger than the top aperture.

[0013] Specifically, an induction door is provided at the first waste disposal opening, an infrared sensor is provided at the bottom of the first waste disposal opening, guide rails are provided on the left and right sides of the first waste disposal opening, the induction door is slidably installed in the guide rails, and a door cylinder is fixedly installed on the upper side of the first waste disposal opening, with the end of the piston rod of the door cylinder connected to the induction door.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention provides an automatic integrated machine for sorting and compressing multiple garbage bins. Different garbage bins are set along the circumference according to the type of garbage, so that different types of garbage can be put into the corresponding garbage bins to achieve direct garbage sorting. The device is cylindrical and has a rotatable compression unit set at the axis. The rotation of the compression unit compresses the garbage in the first garbage bin, thereby increasing the garbage loading capacity.

[0016] 2. This invention adopts a liftable trash can structure, which lifts the first trash can while the compression mechanism compresses the trash inside, and pushes the packaged trash inside the first trash can out from the bottom of the trash can, realizing convenient recycling of trash and effectively solving the problem of trash being difficult to remove because it is tightly stuck to the trash can wall;

[0017] 3. The present invention sets rollers in the support frame and sets locking cylinders with locking blocks at both ends of the crossbeam. During the compression action, the locking blocks are tightly attached to the rollers, which effectively locks the rotational freedom of the compression mechanism, counteracts the reaction force generated when the compression cylinder is pressed down, and improves the stability of the equipment operation.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] In the description of this invention, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0029] like Figures 1-8 As shown, this invention provides an automatic integrated machine for multi-bin collection and compression of waste sorting, including a frame 1 and multiple first waste bins 2, a compression unit 4, and a lifting unit 5 disposed within the frame 1. Waste is put into different first waste bins 2 according to the type of waste. The compression unit 4 compresses the waste according to the stacking height of the waste in the first waste bin 2 to increase the filling capacity of the first waste bin 2. When removing waste, the lifting unit 5 lifts the first waste bin 2 while the compression unit 4 is compressing the waste in the bin, so that the packaged waste in the first waste bin 2 is pressed out from the bottom of the first waste bin 2, realizing convenient waste recycling.

[0030] The frame 1 is cylindrical in shape and includes an openable upper door 11 and a support frame 15. The top and bottom of the upper door 11 are respectively provided with a top plate 14 and a bottom plate 12. An installation plate 13 is also provided inside the upper door 11. The installation plate 13 is fixed in the support frame 15, dividing the chamber inside the frame 1 into an upper chamber for disposing of and compressing waste and a lower chamber for storing waste.

[0031] Multiple first trash cans 2 are symmetrically arranged along the circumference of the mounting plate 13. The design of multiple trash cans makes it easier for users to sort and put different types of trash into the trash cans, so as to achieve classified collection of trash. The first trash cans 2 are preferably designed to have 4, 6, or 8, etc., to collect trash such as plastic products, waste paper, and aluminum cans.

[0032] The upper door 11 has a first garbage disposal opening 111 for disposing of garbage, corresponding to the position of the first garbage bin 2. An openable door is located at the first garbage disposal opening 111, and this door can be hinged or slidably connected to the upper door 11. In a preferred embodiment of the invention, this door is a sensor door 113. An infrared sensor 114 is located at the bottom of the first garbage disposal opening 111 to detect the user's garbage disposal action. Guide rails are provided on the left and right sides of the first garbage disposal opening 111, and the sensor door 113 is slidably installed in the guide rails. A door cylinder 115 is fixedly installed on the upper side of the first garbage disposal opening 111, and the end of the piston rod of the door cylinder 115 is connected to the sensor door 113. Infrared sensor 114 and door cylinder 115 are electrically connected to the controller. When a user needs to throw away trash, the user extends their hand to the sensor door 113. Infrared sensor 114 converts the received diffusely reflected infrared light into an electrical signal and sends it to the controller. The controller controls the piston rod of door cylinder 115 to retract based on the collected electrical signal, thereby opening the sensor door 113. After the trash is thrown away, if the controller detects a signal interruption and exceeds the delay threshold, it controls the piston rod of door cylinder 115 to extend, thereby closing the sensor door 113.

[0033] Furthermore, in some embodiments, a second trash can 3 is also provided on the mounting plate 13 along the circumference. The second trash can 3 is staggered with the first trash can 2, and its diameter is smaller than that of the first trash can 2. It is used to collect hazardous waste such as used batteries and cigarette butts. A second trash disposal opening 112 is provided in the upper door body 11 corresponding to the second trash can 3. The upper door body 11 or the sensor door 113 may be printed with text or patterns indicating the type of trash to be collected, so as to instruct the user to put the corresponding trash into the corresponding trash can.

[0034] On the lower side of the mounting plate 13, corresponding to the positions of the first trash can 2 and the second trash can 3, an openable lower door 16 is provided, which can be opened to remove the trash collected in the trash can.

[0035] The frame 1 is equipped with a compression unit 4, which includes a rotation mechanism, a compression mechanism, and a distance sensor 422. The rotation mechanism includes a rotary motor 411 and a reducer 412 mounted on the base plate 12. The reducer 412 is located at the axis of the frame 1. The output end of the reducer 412 is provided with a column 413 in the vertical direction. The column 413 passes through the mounting plate 13 and extends to the lower side of the top plate 14. A bearing is installed at the axis of the mounting plate 13. The column 413 is fixedly connected to the inner ring of the bearing and is limited in position. The compression mechanism is located on the top of the column. An air pump is installed on the top of the frame 1. A crossbeam 431 is installed radially at the upper end of the column 413. A compression cylinder 436 for compressing garbage is installed vertically on the lower side of the crossbeam 431. The compression cylinder 436 is electrically connected to the controller. A pressure plate 437 is installed at the end of the piston rod of the compression cylinder 436. The size of the pressure plate 437 is smaller than the aperture of the first garbage can 2. Based on the preset pressure, the garbage collected in the first garbage can 2 is compressed, thereby increasing the garbage collection capacity.

[0036] The frame 1 is also equipped with a distance sensor 422 for measuring the stacking height of the garbage in the first garbage bin 2. The distance sensor 422 can be installed on the column 413 or on the top of the frame 1. As a preferred embodiment of the present invention, a bracket 421 is fixedly installed on the lower side of the crossbeam 431. The bracket 421 is fan-shaped. The distance sensor 422 is respectively installed on the lower side of the bracket 421 at the position corresponding to the first garbage bin 2. The controller is electrically connected to the distance sensor 422 and the compression cylinder 436. When the sensor door 113 is closed, the distance sensor 422 detects the stacking height of the garbage in the first garbage bin 2 based on a preset frequency, so that the controller controls the compression unit 4 to rotate above the corresponding first garbage bin 2, and causes the piston rod of the compression cylinder 436 to extend out and compress the garbage in the bin.

[0037] A roller 435 is horizontally arranged in the support frame 15, and the roller 435 is positioned above the first trash can 2. Locking cylinders 432 are positioned opposite each other at both ends of the crossbeam 431. The locking cylinders 432 are electrically connected to the controller. The piston rods of the two locking cylinders 432 are arranged in opposite directions. A locking block 434 is installed at the end of the piston rod of the locking cylinder 432. A limit groove 433 is provided at the end of the crossbeam 431. The locking block 434 is slidably installed in the limit groove 433, serving as a sliding guide. The upper surface of the locking block 434 is tangent to or slightly higher than the lower arc surface of the roller 435. When the locking cylinder... When the piston rod of cylinder 432 extends, the piston rod pushes the locking block 434 into the bottom of the roller 435, so that the locking block 434 and the roller 435 are tightly pressed together. This is used to lock the excess degree of freedom when the compression unit 4 performs the compression action, to ensure the accurate positioning of the pressing position, and to counteract the reaction force of the compression cylinder 436. In addition, the surface contact and fitting structure of the roller 435 and the locking block 434 ensures that the two fit tightly, and the rolling of the roller 435 can reduce the frictional resistance during assembly and operation.

[0038] The compression unit 4 adopts a rotating double cylinder structure, which can simultaneously compress two symmetrically arranged first garbage bins 2. There is no need to design a separate compression cylinder 436 for each first garbage bin 2, simplifying the overall structure. When the garbage bin is full, the compression unit can quickly rotate to the top of the first garbage bin 2 to compress the garbage inside, thereby increasing the amount of garbage collected.

[0039] In the non-compressed state, the crossbeam 431 is located in the middle of two adjacent first trash cans 2, that is, above the second trash can 3, so as to avoid the pressure plate 437 blocking the first trash can 2 or the first trash disposal port 111. At this time, the distance sensor 422 is located directly above each first trash can 2. When the sensor door 113 is closed, it measures the stacking height of the trash in the first trash can 2 based on a preset frequency. When the distance sensor 422 measures that the height of the garbage in the first garbage bin 2 is greater than the preset height, it sends an electrical signal to the controller. The controller controls the rotary motor 411 to drive the reducer 412 to rotate the column 413, so that the crossbeam 431 drives the compression cylinder 436 to rotate above the first garbage bin 2 that needs to be compressed. Then, the controller controls the locking cylinder 432 to push the locking block 434, pushing the locking block 434 to the bottom of the roller 435, so that the locking block 434 and the roller 435 are tightly fitted, providing support for the downward pressure of the compression cylinder 436. Then, the piston rod of the compression cylinder 436 is controlled to extend, and the pressure plate 437 presses the garbage in the first garbage bin 2. After the compression is completed, the piston rod of the compression cylinder 436 is retracted. After the piston rod is retracted, the compression cylinder 436 sends an electrical signal to the controller. The controller controls the piston rod of the locking cylinder 432 to retract and release the locking state. After the piston rod is retracted, the locking cylinder 432 sends an electrical signal to the controller, so that the controller controls the rotary motor 411 to rotate and return the compression unit 4 to its original position.

[0040] In some embodiments, an indicator light is also provided at the first garbage disposal port 111 to indicate whether the first garbage bin 2 can be used. If the garbage in the first garbage bin 2 is full (i.e., the height of the garbage stack in the bin is always greater than the preset height after multiple compressions by the compression unit 4), the indicator light indicates that the first garbage bin 2 is full and disconnects the circuit of the infrared sensor 114 at the first garbage disposal port 111, and the sensor door 113 is always in a closed state.

[0041] To facilitate the collection of garbage from the first garbage bin 2, a lifting unit 5 is also designed in the frame 1. The lifting unit 5 raises the first garbage bin 2 and compresses the garbage through the compression unit 4 to achieve garbage collection. The first garbage bin 2 has a through-hole hollow cylindrical structure and is lined with a garbage bag. In some embodiments, the bottom aperture of the first garbage bin 2 is larger than the top aperture to facilitate pushing the garbage out of the bin.

[0042] The lifting unit 5 includes a lead screw 51, which is located between the base plate 12 and the mounting plate 13, and is arranged parallel to the left and right sides of the first trash can 2. Guide rods 56 are provided on both sides of the lead screw 51. The lower end of the lead screw 51 is rotatably connected to the base plate 12, and the upper end of the lead screw 51 passes through the mounting plate 13 and is rotatably connected to the mounting plate 13. A support plate 55 is sleeved on the lead screw 51. The support plate 55 is arc-shaped and has a threaded bushing. A through hole is provided in the support plate 55 corresponding to the guide rod 56. The support plate 55 is threadedly connected to the lead screw 51 through the threaded bushing. The guide rod 56 passes through the through hole and provides guidance and limitation for the vertical movement of the support plate 55. A support ring 21 is provided on the outer periphery of the first trash can 2. The support ring 21 is fixed to the support plate 55 by bolts. The rotation of the lead screw 51 drives the lifting of the first trash can 2.

[0043] To achieve synchronous rotation of the lead screws 51 on both sides, a chain drive mechanism is adopted, with the lead screws 51 on both sides rotating synchronously under the drive of the same chain 54. A fixing frame is provided on the mounting plate 13, and a lifting motor 52 is mounted on the fixing frame. The lifting motor 52 is located on the side of the first trash can 2 near the axis. A drive wheel 531 is provided at the output end of the lifting motor 52. Multiple transmission wheels are arranged along the circumference of the first trash can 2, and the drive wheel 531 is connected to the transmission wheels via a chain 54. Preferably, there are four transmission wheels, including two first transmission wheels 532 symmetrically arranged on the left and right sides of the first trash can 2 and two second transmission wheels 533 symmetrically arranged on the front side of the first trash can 2. The first transmission wheels 532 are fixedly mounted on the upper end of the lead screws 51, and the second transmission wheels 533 are rotatably connected to the mounting plate 13 via a rotating shaft, rotating synchronously under the drive of the lifting unit 5. Driven by the lifting motor 52, the first transmission wheels 532 on both sides drive the lead screws 51 to rotate synchronously, realizing the automatic lifting of the first trash can 2.

[0044] Furthermore, to prevent trash from being thrown onto the chain 54 and causing the structure to jam, a protective cover 57 is installed at least covering the chain 54 to protect the sprocket and chain 54 structure when trash is thrown.

[0045] A pressure ring 58 is fitted onto the upper side of the first trash can 2. The lower end of the pressure ring is fitted inside the first trash can 2, and the upper end of the pressure ring 58 is funnel-shaped, increasing the size of the top opening of the first trash can 2 to prevent trash from falling onto the mounting plate 13. A trash bag is fitted inside the first trash can 2. The length of the trash bag is longer than the height of the first trash can 2, providing a length redundancy. Its upper opening is folded over and clamped and fixed between the first trash can 2 and the pressure ring 58, thus securing the trash bag.

[0046] When collecting garbage, the staff uses the controller to control the compression unit 4 to compress the garbage in the first garbage bin 2 that needs to be recycled, and keeps the compression unit 4 in a continuous compression state. Then, the controller controls the lifting motor 52 to start, and synchronously rotates the lead screws 51 on both sides. Driven by the lead screws 51, the pallet 55 supports the first garbage bin 2 to move upward. The garbage collected in the garbage bag is placed on the bottom plate 12 in a compressed state. After the first garbage bin 2 is fully lifted, the staff can remove the packaged garbage to achieve convenient recycling. After recycling, the controller sends an electrical signal to the lifting motor 52 to control the lifting motor 52 to rotate in the opposite direction, so that the first garbage bin 2 returns to its position. The piston rod of the compression cylinder 436 retracts. After retracting and entering its position, it sends an electrical signal to the controller, and then controls the piston rod of the locking cylinder 432 to retract. After the piston rod of the locking cylinder 432 retracts, it sends an electrical signal to the controller. The compression unit 4 returns to its position under the drive of the rotating motor. After recycling, the upper door 11 is opened, the pressure ring 58 is lifted, and the garbage bag is put back into the first garbage bin.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
