Description

Technical Field

[0001] The present invention relates to the technical field of garbage bins, and in particular to a garbage bin capable of automatic sorting and classification. Background Art

[0002] A trash bin is a container for storing garbage, and its function is the same as that of a trash can. It is generally square or rectangular. A popular advertising trash bin is commonly used in public places such as communities and parks. When garbage is put in, it will be classified and put in. Garbage classification generally refers to a series of activities that classify, collect, transport and treat garbage according to certain regulations or standards, thereby transforming it into a public resource. The purpose of garbage classification is to increase the resource value and economic value of garbage, reduce the amount of garbage processed and the use of processing equipment, reduce processing costs, and reduce the consumption of land resources. It has social, economic, and ecological benefits. Garbage belongs to the public's private property during the classified storage stage. After being classified and put in by the public, the garbage becomes a regional public resource in the community or community where the public is located. After being classified and transported to a garbage collection point or transfer station, the garbage becomes a non-exclusive public resource. From the methods of classifying domestic garbage in various cities at home and abroad, most of them are classified according to the composition and amount of garbage, combined with the resource utilization and treatment methods of local garbage.

[0003] but:

[0004] 1. At present, people's awareness of classified recycling is not strong, and cultivating awareness of garbage classification and recycling is a relatively long and gradual process, which makes people not classify garbage well when putting it out, and the workload of manual classification and recycling is large, resulting in a low recycling rate;

[0005] 2. Most of the existing trash cans are open, especially those in some forest scenic spots. On rainy days, a large amount of rainwater will enter the trash cans and soak the garbage in the trash cans, making garbage recycling difficult. In addition, some small animals in the forest will drill into the open trash cans and turn out the garbage in the trash cans, which affects the sanitation of the scenic area and is not conducive to environmental protection. Summary of the invention

More specifically, the image data is transmitted to the storage hard disk 215 through an external computer to be compared and sorted with the garbage pictures taken by the sorting camera 214, and the classified delivery is controlled by the PLC controller 216. When the user delivers the garbage, the garbage is put into the upper cover 103 through the delivery port of the upper cover 103 and placed on the temporary storage board 211. At this time, the garbage on the temporary storage board 211 is photographed by the sorting camera 214, and the sorting camera 214 compares and sorts the photographed photos with the photos stored in the storage hard disk 215, which has the advantages of taking pictures of the garbage, comparing and sorting the photographed photos.

[0033] In addition, a dust cover is fixedly installed on one side outer wall of the box body 101 , and a protective cover is fixedly installed on one side outer wall of the box body 101 .

When the overflow detector 307 detects that there is too much garbage in the placement box 301, the motor 2 308 is started at this time, and the motor 2 308 drives the round rod 1 302 to rotate counterclockwise, and the round rod 1 302 drives the mounting block 303 to rotate, and the mounting block 303 drives the telescopic rod 304 to rotate downward. When the telescopic rod 304 rotates, the pressing plate 306 is driven to rotate and press down together with the telescopic rod 304. When the pressing plate 306 is pressed down, the telescopic rod 304 is pulled and extended, and the garbage in the placement box 301 is pressed through the pressing plate 306 and the hinge point between the pressing plate 306 and the telescopic rod 304. It has the advantages of detecting the garbage in the placement box 301 and pressing the overflowing garbage to make room.

[0036] Working principle:

[0037] Step 1: Classification and delivery. The image data is transmitted to the storage hard disk 215 through an external computer and compared with the garbage pictures taken by the sorting camera 214 for sorting. The classified delivery is controlled by the PLC controller 216. When the user delivers the garbage, the garbage is put into the upper cover 103 through the delivery port of the upper cover 103 and placed on the temporary storage board 211. At this time, the garbage on the temporary storage board 211 is photographed by the sorting camera 214. The sorting camera 214 compares the photographed photos with the photos stored in the storage hard disk 215 for sorting. When recyclable garbage is sorted out, the PLC controller 216 controls and starts the motor 1 201 to rotate forward, and the motor 1 201 drives the gear 1 202 to rotate clockwise. The gear 1 202 meshes with the gear 2 203 and drives the gear 2 203 to rotate counterclockwise. The gear 2 203 drives the rotating rod 205 to rotate. Figure 4As shown, the rotating rod 205 drives the fixed block 206 and the connecting plate 207 to rotate obliquely to the left, and the connecting plate 207 drives the rotating plate 208 and the temporary storage plate 211 to move. When the rotating rod 205 rotates, it also drives the pulley 1 204 to rotate counterclockwise. The pulley 1 204 drives the pulley 2 209 to rotate through the transmission belt, and the pulley 2 209 drives the driven rod 210 to rotate. The driven rod 210 drives the temporary storage plate 211 to rotate to the left, so that when the temporary storage plate 211 is tilted to the left, it also rotates to dump the garbage into the placement box 301 for classification and placement of the garbage. If the sorting camera 214 compares the taken photos with the photos stored in the storage hard disk 215 and finds that they are non-recyclable garbage, the PLC controller 216 controls the motor 1 201 to flip it.

[0038] Step 2: overflow pressure, the overflow detector 307 is used to detect the garbage in the placement box 301. When the overflow detector 307 detects that there is too much garbage in the placement box 301, the motor 2 308 is started at this time. The motor 2 308 drives the round rod 1 302 to rotate counterclockwise, and the round rod 1 302 drives the mounting block 303 to rotate. The mounting block 303 drives the telescopic rod 304 to rotate downward. When the telescopic rod 304 rotates, the pressing plate 306 is driven to rotate and press down together with the telescopic rod 304. When the pressing plate 306 is pressed down, the telescopic rod 304 is pulled and extended, and the garbage in the placement box 301 is pressed through the pressing plate 306 and the hinge point between the pressing plate 306 and the telescopic rod 304.
