Description

Technical Field

[0001] This utility model relates to the field of waste sorting technology, specifically a waste sorting device based on image recognition. Background Technology

[0002] Image recognition-based waste sorting is essentially a simulation of the human visual judgment process. By replacing manual sorting with algorithms, it addresses the issue that manual sorting is susceptible to subjective judgment and fatigue. Machines automatically determine the categories and guide the sorting process, significantly improving the efficiency and accuracy of waste sorting. Furthermore, it is unaffected by the environment or time and can accurately distinguish between similar waste, such as plastic bottles and glass bottles, or waste batteries and waste pens.

[0003] For example, patent CN222006183U discloses a waste identification and automatic sorting device, including a brush, a straight cylinder, rotating blades, a waste bin, a rotating disk, a chassis, a shell, and an image recognition system. The device integrates four different types of waste into one unit. It identifies different types of waste through image recognition and controls the movement of a motor based on the image recognition results, achieving precise displacement of the waste bin and rotation of the blades, ultimately realizing automatic waste sorting and collection. The device has a lightweight and compact structure, low processing cost, and reliable operation, which can significantly improve the accuracy of waste sorting and collection, and largely solve the problems of secondary mixing and low efficiency in household waste sorting. However, the amount of waste dumped is generally large, especially when sorting waste at waste collection stations. The dumped waste piles up vertically, obstructing each other and affecting the accuracy of image recognition, which is not conducive to accurately sorting different types of waste.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing waste sorting devices. Utility Model Content

[0005] The purpose of this invention is to provide a waste sorting device based on image recognition, in order to solve the problem mentioned in the background art that the amount of waste dumped is generally large, especially when waste is sorted at the waste station, the dumped waste piles up and blocks each other, affecting the accuracy of image recognition and making it difficult to accurately sort different types of waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a waste sorting device based on image recognition, comprising a conveyor line for transporting sorted waste and a feed hopper fixedly installed above the conveyor line. Multiple sorting openings are evenly spaced on the side of the conveyor line, and a waste bin corresponding to each sorting opening is fixedly installed on the side of the conveyor line. A support frame is fixedly installed on the upper surface of the conveyor line, and a camera for identifying waste types is fixedly installed on the support frame. A pusher plate corresponding to the position of each sorting opening is movably installed on the conveyor line. A separation mechanism for waste separation and auxiliary image recognition is provided on the conveyor line.

[0007] Preferably, a movable bracket is slidably connected to the support frame, and the movable bracket is fixedly connected to the pusher plate; a transverse threaded rod is rotatably installed on the support frame, and the movable bracket is threaded onto the transverse threaded rod.

[0008] Preferably, the separation mechanism includes a guide frame fixedly installed on a support frame, a sliding block is longitudinally slidably installed in the guide frame, a lifting frame is connected to the sliding block, and a lever for actuating and separating waste is provided on the lifting frame.

[0009] Preferably, a cylindrical rod is fixedly connected to the sliding block, and a collar is rotatably sleeved on the cylindrical rod, with the lifting frame fixedly connected to the collar.

[0010] Preferably, a spiral spring is elastically connected between the collar and the cylindrical rod.

[0011] Preferably, the lifting frame is rotatably connected to rollers, and a slide rail is fixedly installed on the inner wall of the conveyor line, with the rollers moving down and engaging with the slide rail for sliding connection.

[0012] Preferably, a longitudinal threaded rod is rotatably connected in the guide frame, and a sliding block is threadedly sleeved on the outside of the longitudinal threaded rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the image recognition-based garbage sorting device identifies and analyzes the garbage transported on the conveyor line through a camera, and sorts it into different garbage bins according to the identified garbage type, resulting in high sorting efficiency.

[0014] The camera identifies images of the waste, and through the threaded transmission of the horizontal threaded rod and the moving bracket, the moving bracket and the pusher plate move in a specific direction. The pusher plate pushes the waste on the conveyor line to the sorting port, through which it enters the corresponding waste bin, thus assisting in the waste sorting process.

[0015] Before image recognition, the control lifting frame moves the lever downward, so that the lever is positioned above the conveyor line. The lever limits and blocks the garbage being transported on the conveyor line, increasing the distance the garbage moves forward and backward. The lifting frame then drives the lever to continue moving. The lever and the lifting frame are connected to a cylindrical rod for transfer. The lever can move and separate the garbage, realizing the separation of stacked garbage and reducing the situation where garbage blocks each other and affects image recognition.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figures 1-3 The present invention provides the following technical solution: a waste sorting device based on image recognition, comprising a conveyor line 1 for conveying sorted waste and a feed hopper 2 fixedly installed above the conveyor line 1. Multiple sorting openings 3 are equally spaced on the side of the conveyor line 1, and a waste bin 4 corresponding to and communicating with the sorting openings 3 is fixedly installed on the side of the conveyor line 1. A support frame 5 is fixedly installed on the upper end face of the conveyor line 1, and a camera 6 for identifying waste types is fixedly installed on the support frame 5. A pusher plate 8 corresponding to the position of the sorting opening 3 is movably installed on the conveyor line 1. A separation mechanism for waste separation and auxiliary image recognition is provided on the conveyor line 1.

[0026] Please see Figure 2 and Figure 3 A movable bracket 7 is slidably connected to the support frame 5, and the movable bracket 7 is fixedly connected to the push plate 8; a transverse threaded rod 9 is rotatably installed on the support frame 5, and the movable bracket 7 is threaded onto the transverse threaded rod 9.

[0027] In the waste collection station, further waste sorting is required. Waste is fed onto conveyor line 1 via hopper 2, which then transports the waste to multiple waste bins 4. During transport, images are captured by camera 6, which transmits the collected image data to the waste sorting management backend program. The backend program controls the motor at the corresponding position on support frame 5, causing the transverse threaded rod 9 to rotate. The transverse threaded rod 9 is threadedly connected to the movable support 7, which, under the threaded transmission, controls the movable support 7 to move directionally on support frame 5. The movable support 7 drives the pusher plate 8 below to move synchronously, pushing the waste on conveyor line 1 towards sorting port 3, thus moving the waste through sorting port 3 to the corresponding waste bin 4, achieving automated waste sorting.

[0028] Example 2: Please refer to Figures 2-6 Based on Embodiment 1, a separation mechanism is also disclosed, the specific structure of which is as follows: The separation mechanism includes a guide frame 10 fixedly installed on a support frame 5. A sliding block 11 is longitudinally slidably installed in the guide frame 10. A lifting frame 12 is connected to the sliding block 11. A lever 13 for actuating and separating waste is provided on the lifting frame 12. A roller 14 is rotatably connected to the lifting frame 12. A slide rail 15 is fixedly installed on the inner wall of the conveyor line 1. The roller 14 moves down and engages with the slide rail 15 for slidable connection. A longitudinal threaded rod 16 is rotatably connected to the guide frame 10. The sliding block 11 is threadedly sleeved on the outside of the longitudinal threaded rod 16.

[0029] Please see Figures 5-7 A cylindrical rod 121 is fixedly connected to the sliding block 11, and a collar 122 is rotatably sleeved on the cylindrical rod 121. The lifting frame 12 is fixedly connected to the collar 122. A spiral spring 123 is elastically connected between the collar 122 and the cylindrical rod 121.

[0030] Before the waste sorting process, the motor on the guide frame 10 controls the longitudinal threaded rod 16 to rotate. The sliding block 11 is threadedly connected to the longitudinal threaded rod 16. Under the threaded transmission, the sliding block 11 is fitted into the guide frame 10 and slides longitudinally. As the sliding block 11 moves down, it drives the lifting frame 12 and the lever 13 to move down synchronously, so that the lever 13 is in contact with the upper end face of the conveyor line 1. The lever 13 isolates the waste on the conveyor line 1, preventing too much waste from moving synchronously to the area below the camera 6 and affecting image recognition.

[0031] The lifting frame 12 continues to move downwards, and the lifting frame 12 drives the lever 13 to press against the surface of the conveyor line 1. At this time, the roller 14 on the side of the lifting frame 12 is engaged in the slide rail 15. Under the action of reverse pressure, the collar 122 on the lifting frame 12 is sleeved on the outside of the cylindrical rod 121 and rotates. During the rotation, the lifting frame 12 pushes the roller 14 to engage in the slide rail 15 and roll. At the same time, the lever 13 below rotates to separate the stacked garbage, so that the garbage is further dispersed, so that the subsequent garbage can be accurately identified and classified when it moves to the bottom of the camera 6, thereby improving the accuracy of garbage classification.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
