Description

Technical Field

[0001] The present invention relates to the technical field of garbage disposal, and in particular to an urban cleaning system based on intelligent sanitation. Background Art

[0002] With the acceleration of urbanization, the urban population continues to increase, and the amount of domestic waste generated also increases. Improper waste disposal will cause serious environmental pollution, including water pollution, soil pollution and air pollution. In order to protect the environment, it is necessary to improve the efficiency and quality of waste disposal. Solid waste disposal vehicles can collect and dispose of urban waste in a timely and efficient manner, reduce the retention time of waste in the city, and improve the sanitation of the urban environment.

[0003] Chinese Patent Publication No.: CN210395210U discloses a garden city intelligent cleaning system, which relates to the field of road cleaning technology and aims to solve the technical problem that when the existing road sweeper is cleaning the road, sanitation workers often do not know how much garbage is inside the garbage collection box and often need to get off the car to check, which reduces the work efficiency. The main points of its technical solution are: a vehicle body, an adsorption tube, an adsorption device, and a garbage collection box. The garbage collection box is arranged on the vehicle body, the adsorption device is arranged on the top of the garbage collection box, the adsorption tube is arranged on one side of the garbage collection box, and a discharge port is arranged at the joint between the garbage collection box and the adsorption tube; a height detection device is arranged on the top of the garbage collection box, the height detection device is electrically connected to a control chip, the control chip is electrically connected to a display device, and the display device is arranged in the vehicle body.

[0004] It can be seen that the above technical solution has the following problems: when the storage space of the storage cavity is filled with garbage, even if the total weight of the garbage does not reach the load-bearing limit of the storage cavity, more garbage cannot be loaded because the space is full. In this case, although the vehicle is still capable of carrying heavier garbage (i.e., it does not exceed the load-bearing limit), the garbage collection amount will be reduced due to space limitations, and the wet garbage will not be effectively utilized. Summary of the invention

[0005] To this end, the present invention provides an urban cleaning system based on intelligent sanitation, which is used to overcome the problem in the prior art that when the storage space of a garbage truck is filled during urban cleaning, the load-bearing limit of the garbage truck is not reached, resulting in low effective garbage loading capacity and low garbage treatment efficiency.

[0006] To achieve the above-mentioned object, the present invention provides an urban cleaning system based on intelligent sanitation, comprising a box body, which is arranged on a vehicle body for transporting garbage;

[0008] A crushing mechanism is arranged on the upper side of the box body close to the lifting mechanism, and is used to receive the solid waste dumped by the lifting mechanism and crush the waste in the waste bin according to a preset crushing force;

[0009] A solid waste compression box, which is arranged below the crushing mechanism, comprises a first compression chamber for storing crushed dry garbage and a second compression chamber for storing crushed wet garbage, the first compression chamber is located above the second compression chamber, and a portion of the connecting surface between the first compression chamber and the second compression chamber is provided with a plurality of grids of preset aperture sizes for separating the crushed solid waste;

[0010] A detection mechanism, which is arranged on the inner surface of the first compression chamber and the second compression chamber, is used to detect the amount of dry garbage accumulated and the amount of wet garbage accumulated, and adjust the preset crushing force and / or preset aperture according to the amount of dry garbage accumulated, the amount of wet garbage accumulated, and the ratio of dry and wet garbage;

[0011] A sewage tank is arranged below the second compression chamber and near the rear of the vehicle, and is used to collect sewage and separate solids and liquids from the garbage during the compression process;

[0012] The enzyme mixing device is arranged below the second compression chamber and close to the sewage tank, and is used to determine the amount of enzyme mixing according to the volume of the wet garbage entering the enzyme mixing device, the volume of the enzyme mixing device, and the humidity of the garbage;

[0013] The compression processing device is respectively arranged on the first compression chamber and the second compression chamber near the rear side of the box body, and is used to push the wet garbage and dry garbage from the rear side of the box body to the front side of the box body for pre-compression, so that the wet garbage falls into the enzyme stirring device, and determines the first pushing force according to the accumulation of dry garbage and the humidity of dry garbage, determines the second pushing force according to the accumulation of wet garbage and the humidity of wet garbage, and determines the number of pushing times according to the initial wet garbage volume and the capacity of the enzyme stirring device, and adjusts the second pushing force according to the initial wet garbage volume, the number of pushing times, and the capacity of the enzyme stirring device.

[0014] Furthermore, the crushing mechanism comprises:

[0015] A crushing part, which is used to crush the solid waste by crushing rollers arranged opposite to each other;

[0016] The support part includes a first movable plate and a second movable plate for closing the garbage dumping port of the box body and a support assembly for supporting the movable plate for opening and closing. The first movable plate and the second movable plate are used to receive the dumped solid waste. After the solid waste is completely dumped, the support assembly controls the first movable plate and the second movable plate to flip and pour the solid waste into the crushing part.

[0017] Furthermore, the detection mechanism is also used to capture images of solid waste accumulation on the first movable plate and the second movable plate, and determine the ratio of dry and wet waste based on the images of solid waste accumulation.

[0018] Furthermore, the detection mechanism detects the first bottom load-bearing capacity of the first compression chamber and the second bottom load-bearing capacity of the second compression chamber respectively after a single solid waste crushing, determines the dry garbage accumulation amount according to the first bottom load-bearing capacity, and determines the wet garbage accumulation amount according to the second bottom load-bearing capacity.

[0019] Furthermore, the detection mechanism determines the crushing accumulation ratio according to the dry garbage accumulation amount and the wet garbage accumulation amount, and adjusts the preset crushing force and / or preset aperture according to the crushing accumulation ratio and the dry-wet garbage ratio.

[0020] Furthermore, a plurality of drainage holes are provided at a position near the sewage tank on one side of the bottom of the second compression chamber, so as to allow the sewage in the wet garbage to flow into the sewage tank through the plurality of drainage holes;

[0021] Wherein, a water level gauge is arranged on the inner wall of the sewage tank to monitor the sewage level in the sewage tank.

[0022] Furthermore, the detection mechanism is also used to monitor garbage humidity data at several positions in the second compression chamber, and determine the garbage humidity of the wet garbage based on the garbage humidity data.

[0023] Furthermore, a retractable plate is provided between the enzyme mixing device and the sewage tank. When the wet garbage falls into the second compression chamber, the retractable plate is in a first position. When the humidity of the garbage reaches a preset humidity of the garbage, the retractable plate is in a second position.

[0024] Wherein, the first position is that the retractable plate is extended to the top of the second compression chamber and contacts the top of the second compression chamber to close the opening between the enzyme mixing device and the sewage tank;

[0025] The second position is when the retractable plate is retracted from the second compression chamber to between the enzyme mixing device and the sewage tank.

[0026] Furthermore, the compression processing device compares the volume of the initial wet garbage with the volume of the enzyme stirring device, and determines the number of pushes according to the comparison result;

[0027] Wherein, if the initial wet garbage volume is larger than the capacity of the enzyme stirring device, the number of pushing times is determined according to the initial wet garbage volume and the capacity of the enzyme stirring device.

[0028] Furthermore, the compression processing device adjusts the second pushing intensity according to the number of pushing times, including:

[0029] If the pushing times are greater than 1, the increase in the second pushing intensity is determined according to the initial wet garbage volume.

[0030] Compared with the prior art, the beneficial effect of the present invention is that the urban cleaning system based on intelligent sanitation of the present invention integrates multiple functions such as lifting, crushing, separation, compression, sewage collection, enzyme treatment and self-cleaning. The garbage is lifted to the feed port by the lifting mechanism, and the crushing mechanism automatically crushes the garbage according to the preset crushing force. At the same time, the first compression chamber and the second compression chamber are set to ensure the automatic separation of dry garbage and wet garbage in solid waste. The wet garbage is automatically pushed into the enzyme mixing device through the compression processing device, and the dry garbage is pre-compressed, and a sewage tank is set to receive sewage. The efficiency of solid waste treatment is improved, and the effective separation of dry garbage and wet garbage in solid waste is achieved. At the same time, the wet garbage is converted into organic fertilizer, the utilization rate of solid waste is further improved, and the effective storage of garbage in the solid waste treatment vehicle is achieved, and the automatic, efficient and accurate treatment of solid waste is further achieved.

[0031] Furthermore, the present invention realizes the intelligent and refined treatment of solid waste by combining the flipping design of the support part and the image analysis function of the detection mechanism. On the one hand, the first movable plate and the second movable plate are set to receive the garbage and automatically flip at the appropriate time; on the other hand, the dry and wet garbage ratio of the solid waste after a single garbage dumping is obtained through image analysis, thereby further improving the efficiency of solid waste treatment, realizing the effective separation of dry garbage and wet garbage in solid waste, and at the same time converting wet garbage into organic fertilizer, further improving the utilization rate of solid waste, realizing the effective storage of garbage in the solid waste treatment vehicle, and further realizing automatic, efficient and accurate treatment of solid waste.

[0032] Furthermore, the present invention determines the accumulation amount of dry garbage and wet garbage, and then calculates the accumulation ratio of crushed garbage, and compares it with the ratio of dry and wet garbage, and adjusts the preset crushing force and / or the size of the preset aperture according to the comparison result, so as to optimize the crushing effect and ensure that the dry and wet garbage can be effectively separated, thereby further improving the efficiency and accuracy of solid waste treatment, realizing effective storage of garbage in solid waste treatment vehicles, and further realizing automatic, efficient and precise treatment of solid waste.

[0033] Furthermore, the present invention sets a retractable plate to optimize the sewage separation efficiency. When the wet garbage enters the second compression chamber, the retractable plate is in the first position, which effectively prevents the wet garbage from directly flowing into the enzyme mixing device, and provides space for the wet garbage to be squeezed and drained in the second compression chamber. And when the humidity of the garbage reaches a preset value, the retractable plate switches to the second position in time, and the wet garbage enters the enzyme mixing device for further decomposition, further converting the wet garbage into organic fertilizer, realizing effective storage of garbage in the solid waste treatment vehicle, and further realizing automatic, efficient and accurate treatment of solid waste.

[0034] Furthermore, the present invention compares the initial wet garbage volume and the capacity of the enzyme stirring device, determines the number of pushing times according to the comparison result, and adjusts the second pushing force according to the number of pushing times, intelligently controls the number of actions and the pushing force of the compression processing device, realizes the automation of wet garbage processing, further converts the wet garbage into organic fertilizer, realizes the effective storage of garbage in the solid waste treatment vehicle, and further realizes automatic, efficient and precise processing of solid waste.

[0045] in,

[0046] A lifting mechanism 1 is arranged at one side of the rear of the box body, and is used to lift the garbage box to the crushing mechanism and dump the solid waste;

[0047] A crushing mechanism, which is arranged on the upper side of the box body close to the lifting mechanism 1, is used to crush the garbage in the garbage bin according to a preset crushing force;

[0048] A solid waste compression box is arranged below the crushing mechanism, and includes a first compression chamber 301 for storing crushed dry garbage and a second compression chamber 302 for storing crushed wet garbage. The first compression chamber 301 is located above the second compression chamber 302. A portion of the connecting surface between the first compression chamber 301 and the second compression chamber 302 is provided with a plurality of grids with preset aperture sizes to separate the crushed solid waste;

[0049] A detection mechanism is arranged on the inner surface of the first compression chamber 301 and the second compression chamber 302, and is used to detect the amount of dry garbage accumulated and the amount of wet garbage accumulated, and adjust the preset crushing force and / or preset aperture according to the amount of dry garbage accumulated, the amount of wet garbage accumulated, and the ratio of dry and wet garbage;

[0050] A sewage tank 6 is arranged below the second compression chamber 302 and near the rear of the vehicle, and is used to collect sewage and separate solids and liquids from the garbage during the compression process;

[0051] The enzyme mixing device 4 is arranged below the second compression chamber 302 and close to the sewage tank 6, and is used to determine the amount of enzyme mixing according to the volume of the wet garbage entering the enzyme mixing device 4, the volume of the enzyme mixing device, and the humidity of the garbage;

[0052] The compression processing device 5 is respectively arranged at the first compression chamber 301 and the second compression chamber 302 near the rear side of the box body, and is used to push the wet garbage and the dry garbage from the rear side of the box body to the front side of the box body for pre-compression, so that the wet garbage falls into the enzyme stirring device 4, and determines the first pushing force according to the dry garbage accumulation amount and the dry garbage humidity, determines the second pushing force according to the wet garbage accumulation amount and the wet garbage humidity, and determines the number of pushing according to the initial wet garbage volume and the volume of the enzyme stirring device. The compression processing device 5 is also used to adjust the second pushing force according to the initial wet garbage volume, the number of pushing times, and the volume of the enzyme stirring device;

[0053] The self-cleaning mechanism is used to clean the box body and achieve internal cleaning of the box body.

[0054] It can be understood that the workflow of the automated solid waste disposal garbage truck is as follows:

[0055] The garbage bin can be lifted to the feed port of the box body by the lifting mechanism 1, and the garbage in the garbage bin is received by the crushing mechanism, which performs preliminary crushing treatment on the solid waste according to the preset crushing force, reducing the volume of the garbage and facilitating subsequent compression. After the garbage crushed by the crushing mechanism enters the box body, based on the different crushing degrees, the dry garbage is left in the first compression chamber 301, and the wet garbage is left in the second compression chamber 302. The detection mechanism monitors the accumulation amount of dry garbage and the accumulation amount of wet garbage in the first compression chamber 301 and the second compression chamber 302 in real time, and adjusts the preset crushing force of the crushing part 201 and the preset aperture of the grid to achieve effective separation of dry and wet garbage. The wet garbage is compressed by the compression processing device 5 and pushed into the enzyme mixing device 4, and the dry garbage is compressed. The enzyme mixing device 4 can further decompose the organic matter in the wet garbage and decompose the wet garbage into useful materials. In the process of pushing, the moisture in the solid waste can flow into the sewage tank 6, and the self-cleaning mechanism can clean the inside of the box body, ensuring that the inside of the box body is clean while ensuring effective garbage storage space and reducing odor.

[0056] In implementation, the value range of the preset crushing force can be determined according to the ratio of dry garbage to wet garbage in solid waste. No specific limitation is made here. As long as the preliminary crushing of dry garbage and the complete crushing of wet garbage can be achieved, the value range of the preset aperture of the grid can be determined according to the degree of crushing of dry garbage and wet garbage. As long as the dry garbage can be left in the first compression chamber 301 and most of the wet garbage can be left in the second compression chamber 302, the value range and preferred value of the preset crushing force and preset aperture can be determined according to actual conditions and will not be elaborated here.

[0057] In a specific embodiment, the box body also includes a storage bin 7, which is used to store the dry garbage compressed in the first compression chamber 301. At the same time, a rotating baffle is set between the first compression chamber 301 and the storage bin 7 near the top of the box body. When the compression processing device 5 is working in the first compression chamber 301, the rotating baffle is in a vertical state with the first compression chamber 301 to compress the dry garbage. After the dry garbage is completely compressed, the rotating baffle is in a parallel state with the first compression chamber 301 to make the compressed dry garbage fall into the storage bin 7. In practice, the rotating baffle can be made of high-strength, wear-resistant, and corrosion-resistant materials, such as high-strength steel plates or special alloy materials, to ensure that the structure remains intact while bearing the pressure of the compression processing device. The material of the rotating baffle is not specifically limited, as long as it can ensure that the structure remains intact while bearing the pressure of the compression processing device, and it will not be repeated here.

[0058] In a specific embodiment, when the compression processing device 5 is working in the first compression chamber 301, the rotating baffle is in a vertical state with respect to the first compression chamber 301. At the same time, a locking device is arranged on the side of the first compression chamber 301 close to the storage bin 7. The locking device is used to ensure that the rotating baffle will not rotate accidentally due to external force during the compression process.

[0059] It can be understood that the volume of compressed wet garbage and the corresponding garbage humidity of the wet garbage are important bases for determining the amount of enzyme to be mixed. The larger the volume of compressed wet garbage, the more enzyme is required. At the same time, since garbage with too high or too low humidity may affect the effect of the enzyme, when determining the amount of enzyme to be mixed, it is necessary to make appropriate adjustments based on the humidity of the garbage to ensure that the enzyme can play its best role and improve the processing efficiency.

[0060] In a specific embodiment, the amount of enzyme mixing is determined according to the compressed wet garbage volume, the volume of the enzyme mixing device, and the garbage humidity of the wet garbage entering the enzyme mixing device 4, and the enzyme mixing amount = k × compressed wet garbage volume × garbage humidity / enzyme mixing device volume × ideal humidity, wherein the compressed wet garbage volume can be obtained according to the image sensor arranged in the detection mechanism; the ideal humidity is the humidity with the highest enzyme activity and the best decomposition effect. Different enzymes have different requirements for humidity. The ideal humidity can be determined according to the type of enzyme used; k is an empirical coefficient determined according to the characteristics of the specific enzyme, the composition of the garbage and other factors, and can be obtained based on several wet garbage decomposition tests. It is not specifically limited here and will not be repeated.

[0061] The city cleaning system based on intelligent sanitation of the present invention integrates multiple functions such as lifting, crushing, separation, compression, sewage collection, enzyme mixing and self-cleaning. The garbage is lifted to the feed port by the lifting mechanism 1, and the crushing mechanism automatically crushes the garbage according to the preset crushing force. At the same time, the first compression chamber 301 and the second compression chamber 302 are set to ensure the automatic separation of dry garbage and wet garbage in solid waste. The wet garbage is automatically pushed into the enzyme mixing device 4 through the compression processing device 5, and the dry garbage is pre-compressed, and a sewage tank 6 is set to receive sewage. The efficiency of solid waste treatment is improved, and the effective separation of dry garbage and wet garbage in solid waste is achieved. At the same time, the wet garbage is converted into organic fertilizer, the utilization rate of solid waste is further improved, and the effective storage of garbage in the solid waste treatment vehicle is achieved, and the automatic, efficient and accurate treatment of solid waste is further achieved.

[0062] Specifically, the crushing mechanism includes:

[0063] A crushing unit 201, which is used to crush the solid waste by crushing rollers arranged opposite to each other;

[0064] The support part 202 includes a first movable plate and a second movable plate for closing the garbage dumping port of the box body and a support assembly for supporting the movable plate for opening and closing. The first movable plate and the second movable plate are used to receive the dumped solid waste, and after the solid waste is completely dumped, the first movable plate and the second movable plate are flipped to pour the solid waste into the crushing part 201.

[0065] It can be understood that the first movable plate and the second movable plate are placed horizontally in the initial state to receive the solid waste dumped from the lifting mechanism 1. The support assembly is used to fix and support the first movable plate and the second movable plate to ensure that the first movable plate and the second movable plate remain stable during the process of receiving the solid waste and flipping. When the garbage is completely dumped, the first movable plate and the second movable plate are flipped according to the flipping angle, so that the solid waste can slide from the first movable plate and the second movable plate and dumped into the crushing part 201, and the crushing part 201 crushes the garbage.

[0066] In a specific embodiment, the support assembly is used to fix and support the first movable plate and the second movable plate to ensure stability during the process of bearing the weight of garbage and flipping. At the same time, the support assembly includes a guide and a limiter to ensure that the first movable plate and the second movable plate flip according to the flip angle to avoid collision or jamming. The flipping method can be achieved by mechanical transmission, hydraulic or pneumatic devices, and the flip angle value range can be determined according to the inclination angle of the crushing wall of the crushing mechanism. Preferably, the first movable plate and the second movable plate are parallel to the inclination angle of the crushing wall after flipping, and the crushing part 201 is a crushing pair of rollers to achieve the crushing of solid waste. The support assembly, the flip angle of the first movable plate and the second movable plate, and the structure of the crushing part 201 can be determined according to actual conditions, and no specific restrictions are made here, as long as the support assembly can be used to fix and support the first movable plate and the second movable plate to ensure stability during the process of bearing the weight of garbage and flipping. The solid waste garbage flipped according to the flip angle can fall completely into the crushing part 201 and be crushed by the crushing part 201, which will not be repeated here.

[0067] In a specific embodiment, the first movable plate and the second movable plate can be foldable, and when the first movable plate and the second movable plate are unfolded to receive garbage, the first movable plate and the second movable plate can be firmly locked without shaking or deformation. In implementation, the connection method of the first movable plate and the second movable plate in the support part 202 is not specifically limited, as long as the first movable plate and the second movable plate can receive the dumped solid waste and the force generated during the flipping process after being unfolded, and can be firmly locked after being unfolded, it will not be described in detail here.

[0068] In practice, the internal structure, relative position and connection method of the crushing part 201 and the supporting part 202 in the crushing mechanism can be adjusted according to actual conditions, and no specific limitation is made here. As long as the crushing part 201 can crush the solid waste, and the supporting part can receive the dumped solid waste and pour the solid waste into the crushing part 201, it will not be repeated here.

[0069] Specifically, the detection mechanism is also used to capture images of solid waste accumulation on the first movable plate and the second movable plate, and determine the ratio of dry and wet waste based on the images of solid waste accumulation.

[0070] It can be understood that the dry-wet garbage ratio is the ratio of dry garbage to wet garbage in the solid waste accumulation image. When the solid waste is dumped onto the first movable plate and the second movable plate, the detection mechanism starts the image acquisition function and automatically takes the solid waste accumulation image. By pre-processing the solid waste accumulation image, the dry-wet garbage ratio can be determined.

[0071] In a specific embodiment, the detection mechanism can pre-process the solid waste accumulation image, including denoising, contrast enhancement, brightness adjustment and other operations to improve the image quality, and determine the garbage accumulation area by analyzing and locating, and then determine the dry and wet garbage ratio based on a pre-trained machine learning model. The machine learning model can be trained using a large number of labeled dry garbage images and wet garbage images to classify dry and wet garbage. In the process of solid waste accumulation image recognition, after the garbage accumulation area is classified, the area ratio of dry garbage and wet garbage can be calculated to determine the dry and wet garbage ratio, and the dry and wet garbage ratio is in the form of a percentage.

[0072] The ratio of dry garbage to wet garbage after the i-th dumping of solid waste is the ratio of the number of pixel points of the dry garbage in the garbage accumulation area in the solid waste image after the i-th dumping of solid waste to the number of pixel points of the wet garbage in the garbage accumulation area in the solid waste image after the i-th dumping of solid waste.

[0073] In a specific embodiment, the detection mechanism can capture images of solid waste accumulation on the first movable plate and the second movable plate through a high-definition camera or an image sensor. The shooting device, installation position and installation angle of the detection mechanism are not specifically limited. As long as the installation position and angle can clearly capture the accumulation of solid waste on the first movable plate and the second movable plate, they will not be elaborated here.

[0074] In another specific embodiment, the detection mechanism may be provided with a multi-angle / multi-point detection device to photograph the accumulation of solid waste on the first movable plate and the second movable plate to obtain a more comprehensive garbage accumulation situation.

[0075] The present invention realizes intelligent and refined solid waste treatment by combining the flip design of the support part 202 and the image analysis function of the detection mechanism. On the one hand, the first movable plate and the second movable plate are set to receive the garbage and automatically flip at an appropriate time; on the other hand, the dry and wet garbage ratio of the solid waste after a single garbage dumping is obtained through image analysis, thereby further improving the efficiency of solid waste treatment, achieving effective separation of dry garbage and wet garbage in solid waste, and converting wet garbage into organic fertilizer, further improving the utilization rate of solid waste, achieving effective storage of garbage in the solid waste treatment vehicle, and further realizing automatic, efficient and accurate treatment of solid waste.

[0076] Specifically, after a single solid waste crushing, the detection mechanism respectively detects the first bottom load of the first compression chamber 301 and the second bottom load of the second compression chamber 302, determines the dry garbage accumulation amount according to the first bottom load, and determines the wet garbage accumulation amount according to the second bottom load.

[0077] It is understandable that by detecting the first bottom load and the second bottom load after each solid waste crushing, the amount of dry garbage accumulated in the first compression chamber 301 and the amount of wet garbage accumulated in the second compression chamber 302 after a single solid waste crushing can be obtained.

[0078] In implementation, weighing sensors can be installed at the bottom of the first compression chamber 301 and the second compression chamber 302 to weigh the garbage in the first compression chamber 301 and the second compression chamber 302. Pressure sensors can also be installed at the bottom of the first compression chamber 301 and the second compression chamber 302 to estimate the dry garbage accumulation amount and the wet garbage accumulation amount by detecting the pressure. No specific limitation is made here. As long as the first bottom bearing capacity of the first compression chamber 301 and the second bottom bearing capacity of the second compression chamber 302 can be detected after a single solid waste crushing through the detection mechanism, the positions of the relevant sensors can also be determined according to actual conditions, which will not be repeated here.

[0079] The amount of wet garbage accumulated after the i-th solid waste crushing is the weighing sensor value at the bottom of the second compression chamber 302 after the i-th solid waste crushing, and the amount of dry garbage accumulated after the i-th solid waste crushing is the weighing sensor value at the bottom of the first compression chamber 301 after the i-th solid waste crushing.

[0080] Specifically, the detection mechanism determines the crushing accumulation ratio according to the dry garbage accumulation amount and the wet garbage accumulation amount, compares the crushing accumulation ratio with the dry-wet garbage ratio, and adjusts the preset crushing force and / or preset aperture according to the comparison result.

[0081] Specifically, if the difference between the crushing accumulation ratio and the dry and wet garbage ratio is greater than or equal to a preset difference, the preset crushing force and / or preset aperture are adjusted;

[0082] If the difference between the crushing accumulation ratio and the dry and wet garbage ratio is less than the preset difference, the preset crushing force and / or preset aperture will not be adjusted.

[0083] It is understandable that by comparing the crushing accumulation ratio with the dry-wet garbage ratio, it is possible to evaluate whether the crushing effect of the crushing mechanism meets the expected dry-wet separation effect. If the difference is lower than the preset difference, it means that the crushing effect is ideal and within an acceptable range; if the difference is greater than or equal to the preset difference, it means that the preset crushing force is too large or the preset aperture is too large, resulting in the failure to effectively separate the dry and wet garbage, so the preset crushing force and / or preset aperture are adjusted according to the actual situation.

[0084] The crushing and stacking ratio of solid waste after the i-th crushing is the amount of dry waste accumulated after the i-th crushing of solid waste and the amount of wet waste accumulated after the i-th crushing of solid waste.

[0085] In implementation, the adjustment amount of the preset crushing force is in the range of 8% to 15% of the preset crushing force, preferably, the adjustment amount of the preset crushing force is 10% of the preset crushing force. The adjustment amount of the preset aperture is in the range of 5% to 10% of the preset aperture, preferably, the adjustment amount of the preset aperture is 8% of the preset aperture. The adjustment amount of the preset crushing force and the adjustment amount of the preset aperture can be determined according to actual conditions, and will not be repeated here.

[0086] The present invention determines the accumulation amount of dry garbage and wet garbage, and then calculates the accumulation ratio of crushed garbage, and compares it with the ratio of dry and wet garbage. According to the comparison result, the preset crushing force and / or the size of the preset aperture are adjusted to optimize the crushing effect, ensuring that the dry and wet garbage can be effectively separated, thereby further improving the efficiency and accuracy of solid waste treatment, realizing effective storage of garbage in solid waste treatment vehicles, and further realizing automatic, efficient and accurate treatment of solid waste.

[0087] Specifically, a plurality of drainage holes are provided at the bottom of the second compression chamber 302 near the sewage tank 6, so as to allow the sewage in the wet garbage to flow into the sewage tank 6 through the plurality of drainage holes;

[0088] Wherein, a water level gauge is arranged on the inner wall of the sewage tank 6 to monitor the sewage level in the sewage tank 6 .

[0089] It can be understood that during the pushing process, the sewage in the wet garbage will flow into the sewage tank 6 through the drainage hole at the bottom of the second compression chamber 302. At the same time, a water level meter is set to monitor the sewage water level in real time. When the water level reaches the preset water level, the drainage operation is automatically triggered to discharge the sewage from the sewage tank 6 to ensure overall stable operation.

[0090] In practice, the number, shape and position of the sewage holes can be determined according to actual conditions, as long as the sewage can be discharged from several sewage holes into the sewage tank 6, which will not be described in detail here.

[0091] Specifically, the detection mechanism is also used to monitor garbage humidity data at several positions in the second compression chamber 302, and determine the garbage humidity of the wet garbage based on the garbage humidity data.

[0092] The humidity of the garbage in the second compression chamber 302 after the i-th solid waste crushing is the sum of the garbage humidity data of the humidity sensors at each position and the weight products corresponding to the garbage humidity data at each position. The weight can be determined according to the garbage stacking position in the second compression chamber 302. Preferably, the weight of the humidity sensor at the garbage stacking position in the second compression chamber 302 is higher, and the weight of the humidity sensor in a more dispersed area is lower. The sum of the weights of several positions is 1, which will not be repeated here.

[0093] In implementation, the several positions can be determined according to actual conditions and are not limited here. As long as the garbage humidity detection of wet garbage can be achieved, it will not be elaborated here.

[0094] Specifically, a retractable plate is provided between the enzyme mixing device 4 and the sewage tank 6. When the wet garbage falls into the second compression chamber 302, the retractable plate is in the first position. When the humidity of the garbage reaches the preset humidity of the garbage, the retractable plate is in the second position.

[0095] The first position is when the retractable plate is extended to the top of the second compression chamber 302 and contacts the top of the second compression chamber 302 to close the opening between the enzyme mixing device 4 and the sewage tank 6;

[0096] The second position is when the retractable plate is retracted from the second compression chamber 302 to between the enzyme mixing device 4 and the sewage tank 6 .

[0097] It can be understood that when the wet garbage is fed into the second compression chamber 302, the retractable plate is in the first position, preventing the wet garbage from directly entering the enzyme mixing device 4. At this time, the wet garbage is squeezed and drained in the second compression chamber 302, and the sewage flows into the sewage tank 6; when the garbage humidity reaches the preset garbage humidity, the retractable plate switches from the first position to the second position and enters the enzyme mixing device 4 for further processing.

[0098] In implementation, the value range of the preset garbage humidity can be determined according to the required moisture content for preparing fertilizer, which will not be elaborated here.

[0099] The present invention sets a retractable plate to optimize the sewage separation efficiency. When the wet garbage enters the second compression chamber 302, the retractable plate is in the first position, which effectively prevents the wet garbage from directly flowing into the enzyme mixing device 4, and provides space for the wet garbage to be squeezed and drained in the second compression chamber 302. When the humidity of the garbage reaches a preset value, the retractable plate switches to the second position in time, and the wet garbage enters the enzyme mixing device 4 for further decomposition, further converting the wet garbage into organic fertilizer, realizing effective storage of garbage in the solid waste treatment vehicle, and further realizing automatic, efficient and accurate treatment of solid waste.

[0100] Specifically, the compression processing device 5 compares the volume of the initial wet garbage with the volume of the enzyme stirring device, and determines the number of pushes according to the comparison result;

[0101] Wherein, if the initial wet garbage volume is larger than the volume of the enzyme stirring device, the number of pushes is determined according to the initial wet garbage volume and the volume of the enzyme stirring device;

[0102] If the initial wet garbage volume is less than or equal to the volume of the enzyme stirring device, the number of pushing times is one.

[0103] Specifically, the compression processing device 5 adjusts the second pushing intensity according to the number of pushing times, including:

[0104] If the pushing times are greater than 1, the increase in the second pushing intensity is determined according to the initial wet garbage volume.

[0105] It is understandable that the initial wet garbage volume is the volume of wet garbage that falls into the compression processing device 5. The wet garbage image can be obtained according to the image sensor in the detection mechanism. According to the shape, size and distribution of the garbage in the image, the system calculates the volume of the initial wet garbage. If the initial wet garbage volume is larger than the volume of the enzyme stirring device, it means that all the wet garbage cannot be completely sent into the enzyme stirring device by one push. Therefore, it is necessary to determine the number of pushes required according to the initial wet garbage volume and the volume of the enzyme stirring device. After determining the number of pushes, the pushing force is adjusted according to the number of pushes. If the number of pushes is greater than 1, it means that the initial wet garbage volume is large and multiple pushes are required. Then, the increase in the second pushing force during each push is determined according to the initial wet garbage volume, so as to ensure that the wet garbage can enter the enzyme stirring device more smoothly and evenly, while avoiding excessive pressure or damage to the enzyme stirring device.

[0106] In implementation, if the initial wet garbage volume is larger than the volume of the enzyme mixing device 4, the increase in the second pushing force is determined according to the percentage by which the initial wet garbage volume exceeds the volume of the enzyme mixing device 4. For example, when the initial wet garbage volume exceeds the volume of the enzyme mixing device 4 by 50%, the increase in the second pushing force is 80% to 100% of the second pushing force. Preferably, when the initial wet garbage volume exceeds the volume of the enzyme mixing device 4 by 50%, the increase in the second pushing force is 90% of the second pushing force. No specific limitation is made here, as long as the wet garbage can be pushed into the enzyme mixing device 4 in batches, it will not be repeated here.

[0107] The present invention compares the initial wet garbage volume and the capacity of the enzyme stirring device, determines the number of pushing times according to the comparison result, and adjusts the second pushing force according to the number of pushing times, intelligently controls the number of actions and the pushing force of the compression processing device 5, realizes the automation of wet garbage processing, further converts the wet garbage into organic fertilizer, further improves the utilization rate of solid waste, realizes the effective storage of garbage in the solid waste treatment vehicle, and further realizes automatic, efficient and precise processing of solid waste.
