Description

Technical Field

[0001] The present invention relates to the technical field of garbage detection, in particular to a device for identifying perishable garbage based on visual analysis. Background Art

[0002] With the development of urban socio-economic development, the amount of domestic waste generated in my country's cities continues to increase. The composition of domestic waste has also changed in response to shifts in consumption patterns, but it still exhibits significant characteristics such as high organic matter content, high water content, and low calorific value for mixed collections. Perishable waste accounts for up to 70% of domestic waste. Perishable waste primarily refers to easily corruptible and biodegradable waste generated during food processing and food consumption. This includes kitchen waste from canteens, hotels, and restaurants, as well as vegetable and fruit waste, rotting meat, meat scraps, eggshells, and livestock and poultry offal generated by farmers' markets and wholesale agricultural product markets.

[0003] Chinese patent announcement number CN207188258U proposes a perishable garbage identification device, including a main body, in which a conveying device, a detection device and a controller are installed; at least two outlets and at least one inlet are provided on the outer wall of the main body; a first inlet and a first outlet are provided on the outer walls of the main body corresponding to the two ends of the conveying device, respectively, and a second outlet is provided on the outer wall of the adjacent main body, and the second outlet is connected to the conveying device through a second outlet channel; a limiting device and a pushing device are provided at the intersection of the conveying device and the second outlet channel; a detection device is provided above the conveying device; and a controller is connected to the detection device, the conveying device, the limiting device and the pushing device respectively. The above method detects the perishable garbage in the perishable garbage bags and separates the garbage bags that do not contain a certain amount of perishable garbage, thereby achieving the purpose of classification.

[0004] In daily life, people usually mix perishable garbage with garbage containing liquid (such as bottles and cans) in garbage bags, or mix food soup with perishable garbage. When the liquid in the bottles and cans is poured out, there is more liquid and less perishable garbage in the garbage bag. The liquid affects the recognition effect of the detection device, and most people dump the garbage in the garbage bag into the trash can at one time, which easily forms an accumulation on the conveying device, and the garbage below the accumulation cannot be identified and classified. Summary of the Invention

[0005] The present invention provides a perishable garbage identification device based on visual analysis. It uses a filter to separate solids and liquids in garbage. When the garbage is in a static water control stage, a water pipe guides the liquid in the liquid collection area into the air supply bin. When the liquid weight accumulates to a preset weight, the liquid applies pressure to the air supply plate and uses air to drive the resistance plate upward to lift the garbage above the filter. The reciprocating movement of the conveying device and the stripping action of the stripping mechanism are coordinated to solve the problems raised in the above-mentioned background technology, namely: To achieve the above-mentioned purpose, the perishable garbage identification device based on visual analysis includes a garbage bin, a detection device, a conveying device and a pushing device, wherein two groups of detection devices are arranged above the conveying device, a feed port is provided on one side of the garbage bin, a guide plate is arranged on the inner side of the feed port, and a static box for accommodating garbage is provided above the conveying device at the guide end, a liquid collecting box is fixedly provided below the static box, a feeder is provided inside the static box, the top of the feeder receives the garbage and the bottom extends into the liquid collecting box, the garbage is controlled and static on the feeder, the static box is responsible for guiding the collected liquid into the liquid collecting box, the liquid collecting box has a movably provided air supply plate, when the weight of the liquid on the air supply plate reaches a preset weight, the liquid drives the air supply plate to press the air in the liquid collecting box, and the garbage height on the top of the feeder is lifted by means of air pressure, and the stripping mechanism cooperatively arranged between the detection devices on both sides strips the lifted garbage from the feeder, thereby realizing multiple identification and classification of accumulated garbage.

[0006] The top of the feeder is a filter screen that separates garbage from liquid. The bottom of the filter screen has a vertical rod that passes through the static box and the conveying device. The filter screen is movably arranged in the static box and is used to separate the interior of the static box into a material collection area and a liquid collection area. The material collection area is used to accommodate water-controlled static garbage, and the liquid collection area is used to store liquid dripping from the garbage.

[0007] A water pipe connected to the liquid collection area is provided at the bottom of the static box. The bottom of the water pipe extends above the air supply plate and transports the liquid in the liquid collection area to its surface to apply pressure to the air supply plate through the weight of the liquid.

[0008] The two sides of the liquid collecting box cooperate with the air supply plate to form an air supply bin for accommodating the liquid transported from the water pipe.

[0009] The middle part of the liquid collecting box is an exhaust bin, and a resistance plate fixed to the vertical pole is arranged inside the exhaust bin. The exhaust bin is connected to the air supply bin through an air supply channel.

[0010] The air supply channel is used to transport air into the exhaust bin to force the resistance plate to move upwards and indirectly push the garbage out.

[0011] The stripping mechanism includes a hydraulic rod arranged between the conveying devices on both sides and fixed to the garbage box, and a stripping plate fixed to the telescopic end of the hydraulic rod. The stripping plate can strip out the garbage on the top of the static box, and the hydraulic rod can adjust the depth of the garbage intercepted by the stripping plate to adapt to actual conditions.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The filter is used to separate the solid and liquid in the garbage, and when the garbage is in the static water control stage, the water pipe guides the liquid in the liquid collection area into the air supply bin. When the liquid weight accumulates to the preset weight, the liquid pressurizes the air supply plate and drives the resistance plate upward with the help of air to lift the garbage above the filter. The reciprocating movement of the conveying device and the stripping action of the stripping mechanism are coordinated to detect garbage of different depths and improve the accuracy and efficiency of garbage classification.

DETAILED DESCRIPTION

[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] When the liquid in the bottle is poured out, the garbage bag contains more liquid and less perishable garbage. The liquid affects the recognition effect of the detection device 101. In addition, most people dump the garbage in the garbage bag into the garbage bin 100 at one time, which easily forms a pile on the conveyor 102. The garbage below the pile cannot be identified and classified. The present invention provides a perishable garbage identification device based on visual analysis. Figure 1-Figure 3 As shown, it includes a trash bin 100, a detection device 101, a conveying device 102 and a pushing device 103, wherein two sets of detection devices 101 are arranged above the conveying device 102, a feed port is provided on one side of the trash bin 100, a guide plate is provided inside the feed port, a stationary box 120 for accommodating trash is provided above the conveying device 102 at the end of the guide, a liquid collecting box 140 is fixedly provided below the stationary box 120, a feeder 130 is provided inside the stationary box 120, the top of the feeder 130 receives the trash from the guide plate, and the bottom extends to the liquid collecting box 140, and the trash is placed in the Water control and stillness are achieved on the feeder 130, and the stillness box 120 is responsible for guiding the collected liquid into the liquid collecting box 140. The liquid collecting box 140 has a movable air supply plate 141. When the weight of the liquid on the air supply plate 141 reaches a preset weight, the liquid drives the air supply plate 141 to press the air in the liquid collecting box 140, and the air pressure is used to lift the height of the garbage on the top of the feeder 130. After identification by the detection device 101, the peeling mechanism 110 cooperatively arranged between the detection devices 101 on both sides peels the lifted garbage from the feeder 130, thereby realizing multiple identification and classification of accumulated garbage.

[0017] First, the entire system is controlled by an intelligent panel. The following is a brief introduction to the garbage detection process: Under normal circumstances, the winding devices at both ends of the conveyor 102 move the static box 120 to the position as shown in the figure. Figure 2 In the state shown, the end of the guide plate is located in the static box 120, and the conveying device 102 moves to the left following the garbage sliding on the guide plate, so that the garbage can be evenly covered on the top of the feeder 130, and when the end of the guide plate is separated from the static box 120, the static box 120 moves to the right detection area, and the other side is the left detection area; at this time, combined with Figure 4 As shown, the stationary box 120 is located in the left detection area, and the moving state of the stationary box 120 is: firstly detected in the right detection area, and then moved to the left detection area for detection. During the movement of the stationary box 120 from the right to the left, the stripping mechanism 110 strips off part of the garbage on the feeder 130, as follows: Return to Figure 2As shown, the top of the feeder 130 is a filter 131 for separating garbage from liquid, and the bottom of the filter 131 has a vertical rod that passes through the static box 120 and the conveying device 102. The filter 131 is movably arranged in the static box 120 and is used to separate the interior of the static box 120 into a collection area 121 and a liquid collection area 122. Specifically, when the garbage slides down the guide to the static box 120, the conveying device 102 drives the static box 120 to move to the left. The collection area 121 is used to accommodate the garbage that is controlled to be static, and the liquid collection area 122 is used to store the liquid dripping in the garbage, that is, the garbage is evenly spread on the filter 131 to be static and water-controlled, while the liquid flows through the filter 131 to the liquid collection area 122. This process is a solid-liquid separation process.

[0018] In order to transport the liquid collected in the liquid collecting area 122 to the liquid collecting box 140, the following Figure 5 、 Figure 6 As shown, a water pipe 124 connected to the liquid collecting area 122 is provided at the bottom of the static box 120. The bottom of the water pipe 124 extends to the top of the air supply plate 141 and transports the liquid in the liquid collecting area 122 to its surface, so as to apply pressure to the air supply plate 141 through the weight of the liquid. At the same time, the air supply plates 141 on both sides of the liquid collecting box 140 are driven downward by the weight of the liquid. Then, on the other hand, the air supply plates 141 on both sides of the liquid collecting box 140 cooperate with each other to form an air supply bin 200 for accommodating the liquid transported from the water pipe 124. In this way, the liquid guided by the water pipe 124 to the liquid collecting box 140 is collected in the air supply bin 200, and the liquid collecting box 140 is The middle part of 0 is the exhaust bin 300, and the exhaust bin 300 is equipped with a resistance plate 132 fixed to the vertical pole. The exhaust bin 300 is connected to the air supply bin 200 through an air supply channel 143. When the weight of the liquid in the air supply bins 200 on both sides reaches the preset weight (that is, the pressure of the liquid on the air supply plate 141 can force the resistance plate 132 to move up and lift the garbage to the sea), the air supply plate 141 gradually presses the air in the air supply bin 200 downward to be transported to the air supply channel 143, and the air supply channel 143 is used to transport air into the exhaust bin 300 to force the resistance plate 132 to move up and indirectly push the garbage upward, thereby using air to push the resistance plate 132 to move up.

[0019] Specifically at work (combined with Figure 2-Figure 6 As shown): When the stationary box 120 moves to Figure 2When the garbage on the filter screen 131 is in the static water control stage, solid-liquid separation is achieved under the action of the filter screen 131, and the liquid is introduced into the air supply bin 200 through the water pipe 124 for storage. When the weight of the liquid in the air supply bin 200 reaches the preset weight, at this time, the air supply plate 141 is driven by the weight of the liquid, and the air supply plate 141 uses the air to push the resistance plate 132 upward, that is, the filter screen 131 pushes the upper garbage upward, and then it is identified by the right detection device 101, wherein the detection device 101 collects the garbage image and identifies it, calculates the proportion of perishable garbage in the whole and compares it with the set threshold. If it exceeds the set threshold, it starts Figure 1 The peeling mechanism 110; The stripping mechanism 110 includes a hydraulic rod 112 disposed between the conveying devices 102 on both sides and fixed to the trash bin 100, and a stripping plate 111 fixed to the telescopic end of the hydraulic rod 112. The stripping plate 111 can strip the garbage from the top of the static box 120, and the hydraulic rod 112 can adjust the depth of the garbage intercepted by the stripping plate 111 to adapt to actual conditions. The height of the stripping plate 111 is adjusted by the hydraulic rod 112 to strip the garbage that has been detected. Combine Figure 3 As shown, there are discharge ports 123 for garbage discharge on both sides of the top of the static box 120. When the garbage on the filter screen 131 is ejected, the right detection device 101 is used for detection. The conveying device 102 drives the static box 120 to move to the left detection area. Under the interception of the stripping plate 111, the garbage on the top of the filter screen 131 is stripped onto the conveying device 102. Figure 4 As shown in the state, at this time, the position corresponding to the intercepted garbage is as follows Figure 7 As shown, a storage box 104 for sorting and storing garbage is provided inside the garbage bin 100. The storage box 104 has a number of compartments, and each compartment corresponds to a set of pushing devices 103 on the opposite side. That is, if the proportion of perishable garbage intercepted exceeds a set threshold, the corresponding pushing device 103 pushes the garbage on the conveyor 102 into the corresponding compartment for storage; Furthermore, as the static box 120 moves to the left detection area, the weight of the garbage on the filter screen 131 is reduced, and the water control process is still in progress, the garbage on the filter screen 131 rises again and is detected by the left detection device 101. The detection principle is the same as that on the right side, and no further details are given here. After the detection is completed, the conveying device 102 drives the static box 120 to move to the right, and the stripping plate 111 strips off a part of the garbage again, and the stripped garbage corresponds to Figure 7The pushing device 103 is located in the middle position. According to the detection result, the pushing device 103 pushes the garbage to the corresponding compartment. Among them, the leftmost compartment in the storage box 104 contains garbage whose proportion does not exceed the set threshold. That is, the garbage on the filter 131 is driven back and forth by the conveying device 102 to move the static box 120 left and right, and the garbage is gradually peeled off from the filter 131.

[0020] That is to say, the filter 131 is used to separate the solid and liquid in the garbage, and when the garbage is in a static water control stage, the water pipe 124 introduces the liquid in the liquid collection area 122 into the air supply bin 200. When the weight of the liquid accumulates to a preset weight, the liquid applies pressure to the air supply plate 141 and drives the resistance plate 132 upward with the help of air, so as to lift the garbage above the filter 131, coordinate the reciprocating movement of the conveying device 102 and the stripping action of the stripping mechanism 110, realize the detection of garbage of different depths, and improve the accuracy and efficiency of garbage classification.

[0021] It is worth noting that, since the air supply plate 141 is elastically connected to the inner wall of the air supply bin 200 by a tension spring 142, the bottom of the air supply plate 141 is connected to a drain pipe 144 that passes through the liquid collecting box 140. The drain pipe 144 is used to drain the liquid on the air supply plate 141 from the air supply bin 200 when the test is completed. After the detection is completed, the valve on the drain pipe 144 is opened (not shown in the figure). The valve can be an electric valve, which is a prior art. The liquid accumulated on the air supply plate 141 is discharged, and the air supply plate 141 is pulled upward and reset in the opposite direction under the elastic action of the tension spring 142.

[0022] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely preferred examples of the present invention and are not intended to limit the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention.
