Description

Technical Field

[0001] The present invention relates to the technical field of waste incineration treatment, and particularly to a waste feeder for a waste incinerator. Background Art

[0002] In waste treatment, waste incineration is one of the most widely used waste treatment methods. Waste incineration treatment is to put waste into an incinerator for combustion, release heat energy, recover the preheat and then supply heat or generate electricity, which has great advantages compared with other waste treatment methods.

[0003] A waste incinerator is a device for incinerating waste. The waste burns in the furnace chamber, turns into waste gas and enters the secondary combustion chamber, where it burns completely under the forced combustion of the burner, and then enters the spray dust collector. After dust removal, it is discharged into the atmosphere through the chimney. A waste incinerator generally consists of four major systems: a waste pretreatment system, an incineration system, a smoke biochemical dust removal system, and a gas generator (auxiliary ignition and incineration).

[0004] The patent document with the application number CN202023039050.0 discloses a feeding device for a waste incinerator. The feeding device includes a storage hopper, and a displacement mechanism for driving the storage hopper to move towards the incinerator is arranged below the storage hopper. A material cleaning mechanism for driving the storage hopper to turn vertically is arranged on the displacement mechanism. During operation, the operator loads waste into the storage hopper at one end of the track far from the incinerator, and then controls the driving motor to drive the installation box to move on the track; when the storage hopper moves to the designated dumping position, the second hydraulic cylinder is controlled, and the second hydraulic cylinder extends to drive the storage hopper to turn, and the waste in the storage hopper then enters the incinerator. If the waste in the storage hopper is not completely dumped, the operator can control the cylinder, and the cylinder drives the scraper to move, thereby pushing the remaining waste in the storage hopper into the incinerator. The feeding device for the waste incinerator relies on the reciprocating movement of the storage hopper to put waste into the waste incinerator. The work done when the storage hopper is far from the incinerator is useless work, and this feeding device cannot continuously supply materials to the waste incinerator.

[0005] Some feeding devices for waste incinerators rely on conveyor belts to supply materials to the incinerator. Although they can continuously supply materials to the waste incinerator, dirt on the waste is easily attached to the conveyor belt. When the part of the conveyor belt with dirt moves to the lower part, the dirt on the conveyor belt is easily dropped. Therefore, a dirt cleaning component needs to be set for the conveyor belt.

[0006] In the conventional technology, the suction force of a suction fan is used to collect dirt on the lower conveyor belt part. Generally, the suction force of the suction fan is constant. However, since there is more dirt in some areas on the surface of the conveyor belt and less dirt or dust in some areas, a larger suction force is required in the areas with more dirt, while a smaller suction force or even no suction force is needed in the areas with less dirt. When cleaning the conveyor belt by suction, if the suction fan maintains a large suction force throughout the process, when the area with less dirt on the conveyor belt passes through the suction machine, the large suction force maintained by the suction fan is regarded as a waste of energy. On the other hand, if the suction fan maintains a small suction force throughout the process, when the area with more dirt on the conveyor belt passes through the suction fan, the cleaning effect will be poor.

[0007] Similarly, in the conventional technology, when using a scraper to scrape the dirt on the conveyor belt, generally, the extrusion force of the scraper on the conveyor belt is constant. The greater the extrusion force, the better the scraping effect. However, the greater the extrusion force of the scraper on the conveyor belt, the greater the friction force during the movement of the conveyor belt, which in turn leads to greater energy consumption of the motor driving the conveyor belt. Since there is more dirt in some areas on the surface of the conveyor belt and less dirt in some areas, of course, a larger extrusion force needs to be maintained between the scraper and the conveyor belt in the areas with more dirt, while a larger extrusion force does not need to be maintained between the scraper and the conveyor belt in the areas with less dirt. When using the scraper to scrape and clean the conveyor belt, if the scraper and the conveyor belt maintain a large extrusion force throughout the process, when the area with less dirt on the conveyor belt passes through the scraper, the large extrusion force of the scraper on the conveyor belt will increase the energy consumption of the motor driving the conveyor belt. And the long-term high friction force between the scraper and the conveyor belt will reduce the service life of the conveyor belt. Summary of the Invention

[0008] The technical problem to be solved by the present invention is a garbage feeder of a waste incineration boiler that can automatically adjust the friction force between the scraper and the conveyor belt and the suction force of the suction fan according to the amount of dirt on the conveyor belt.

[0009] A waste feeder for a waste incineration boiler, comprising a housing. An inlet is provided at the upper end of the housing, and an outlet is provided at one end in the length direction of the housing. A conveyor belt is installed inside the housing. One end of the conveyor belt penetrates through the outlet. A plurality of iron bars are inlaid and fixed inside the conveyor belt. Isolation belts are fixed at both ends of the conveyor belt in the width direction of the housing. A suction assembly is arranged inside the housing below the conveyor belt; the suction assembly includes a collection assembly. An air suction hood is elastically slidably connected above the collection assembly. The air suction hood is communicated with the collection assembly through a corrugated pipe and a suction fan. The upper end of the air suction hood is open. Electromagnets are inlaid and fixed at both ends of the air suction hood in the width direction of the housing. A scraper and a magnetic sensor are respectively arranged at both ends of the air suction hood in the length direction. The magnetic sensor is closer to the outlet of the housing than the scraper. The scraper is elastically slidably connected with the air suction hood. The upper end of the scraper contacts the lower end surface of the straight part below the conveyor belt between the two isolation belts. A conductive slider is fixed on the scraper. A resistance strip is fixed on the air suction hood. The conductive slider is electrically slidably connected with the resistance strip. A photographing module is fixed inside the housing. The photographing module can photograph the image of the lower end surface of the conveyor belt above the air suction hood. The magnetic sensor and the photographing module are electrically connected to the controller through an image recognition module. A power supply, a current detection module, the resistance strip and the conductive slider form a series circuit. The current detection module, the controller, the suction fan and the electromagnet are electrically connected.

[0010] Specifically, a cleaning assembly and a scraping assembly are arranged inside the housing below the conveyor belt. The suction assembly is located between the cleaning assembly and the scraping assembly. The cleaning assembly is farther from the outlet of the housing than the scraping assembly.

[0011] Specifically, the plurality of iron bars are evenly arranged along the movement track of the conveyor belt.

[0012] Specifically, the collection assembly includes a box body fixed inside the housing. A through hole is provided on one side of the box body. A filter screen is fixed in the through hole. A storage box is slidably inserted on the other side of the box body. The inside of the box body is communicated with the outlet end of the suction fan. The inlet end of the suction fan is communicated with one end of the corrugated pipe. The other end of the corrugated pipe is fixedly communicated with the lower end of the air suction hood.

[0013] Specifically, the air suction hood can slide in the height direction of the housing. A plurality of vertical fixing rods are fixed at the upper end of the box body. The fixing rods are slidably connected with the air suction hood. A second spring is sleeved on the fixing rods. One end of the second spring is fixedly connected with the air suction hood, and the other end of the second spring is fixedly connected with the box body.

[0014] Specifically, the scraper can slide in the height direction of the housing. A vertical chute is provided at the upper end of the air suction hood. The lower end of the scraper is slidably arranged in the chute. The lower end of the scraper is connected with the bottom of the chute through a third spring.

[0015] Specifically, the shoveling component includes a collection box fixed inside the housing. On the upper side of the collection box, which is far from the housing outlet in the length direction of the housing, an inclined sliding cavity is opened. A shovel plate is slidably arranged in the sliding cavity. The upper end of the shovel plate contacts the lower end face of the lower straight part of the conveyor belt between the two isolation belts. A first spring is arranged in the sliding cavity. One end of the first spring is fixedly connected to the shovel plate, and the other end of the first spring is fixedly connected to the collection box.

[0016] Specifically, the cleaning component includes a lifting plate. A cleaning sponge is fixed to the upper end of the lifting plate. The upper end of the cleaning sponge contacts the lower end face of the lower straight part of the conveyor belt between the two isolation belts. Two connecting plates are fixed inside the housing below the conveyor belt along the length direction of the housing. The connecting plates are arranged vertically. The lifting plate and the cleaning sponge are located between the two connecting plates. A plurality of vertical spring telescopic rods are arranged below the lifting plate. The upper end of the spring telescopic rod is fixedly connected to the lifting plate, and the lower end of the spring telescopic rod is fixedly connected to the bottom plate of the housing. A plurality of nozzles are fixed on the opposite end faces of the two connecting plates. The nozzles are communicated with a water supply device. Drainage holes are opened on the housing between the two connecting plates.

[0017] Specifically, the width a of the inner cavity of the suction hood is greater than the distance between two adjacent iron bars on the straight part of the conveyor belt. The width a of the inner cavity of the suction hood and the distance between two adjacent iron bars on the straight part of the conveyor belt differ by the position of one iron bar body. The length of the electromagnet is equal to the width a of the inner cavity of the suction hood. The contact line between the upper end of the scraping plate and the conveyor belt is flush with the inner wall of the suction hood perpendicular to the length direction of the housing and far from the housing outlet. When two adjacent iron bars on the lower straight part of the conveyor belt are above the suction hood, the magnetic force sensor senses one of the iron bars above the suction hood and sends a signal to the controller. After receiving the signal from the magnetic force sensor, the controller starts the photographing module. The photographing module can photograph the lower end face part of the lower straight part of the conveyor belt above the suction hood.

[0018] Specifically, drive rollers are rotatably connected to both the inner side and the outer side of the housing. The two drive rollers are connected by a conveyor belt. Any one of the drive rollers is driven by a motor. Two fixing plates are fixed inside the housing, arranged one above the other. The upper end of the upper fixing plate slides in contact with the lower end of the upper straight part of the conveyor belt, and the lower end of the lower fixing plate slides in contact with the upper end of the lower straight part of the conveyor belt.

[0019] 1. The present invention uses a conveyor belt to transport garbage into the garbage incinerator, which can continuously transport garbage into the garbage incinerator, and has a high efficiency of transporting garbage into the garbage incinerator.

[0020] 2. By arranging a suction component inside the housing and being able to select the extrusion force between the scraper and the conveyor belt according to the amount of dirt on the conveyor belt, when there is more dirt in some areas of the conveyor belt, the extrusion force between the scraper and the conveyor belt is large, which can effectively clean the areas with more dirt on the conveyor belt. When there is less dirt on the conveyor belt, the extrusion force between the scraper and the conveyor belt decreases, which can reduce the friction during the operation of the conveyor belt and the energy consumption of the motor driving the conveyor belt movement. At the same time, the service life of the conveyor belt can be increased.

[0021] 3. When the extrusion force between the scraper and the conveyor belt changes, the power of the exhaust fan changes accordingly. When the extrusion force between the scraper and the conveyor belt increases, the downward travel distance of the scraper increases, and accordingly the power of the exhaust fan increases, which can ensure the cleaning effect on the dirt on the conveyor belt. When the extrusion force between the scraper and the conveyor belt decreases, the downward travel distance of the scraper decreases, and accordingly the power of the exhaust fan decreases, which can reduce the energy consumption of the exhaust fan.

[0022] 4. The part of the conveyor belt between two adjacent iron bars is the area to be processed. Multiple iron bars divide the conveyor belt into multiple areas to be processed. With the cooperation of the iron bars, the magnetic sensor and the photographing module, the photographing module can successively take pictures of the images of the areas to be processed. Subsequently, after the image information of the processed area is processed by the image recognition module, a signal is sent to the controller. The controller adjusts the magnetic suction force of the electromagnet according to the received signal, and can adjust the extrusion force between the scraper and the conveyor belt according to the amount of dirt in the area to be processed. And it can successively analyze and process the areas to be processed, which can ensure the comprehensive cleaning of the conveyor belt.

[0023] 5. By arranging a scraping component, the scraping component can scrape off the larger-volume garbage adhering to the conveyor belt. By arranging a cleaning component, the conveyor belt can be further cleaned. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0040] Embodiment 1: As shown in Figures 1 - 15 , a garbage feeder of a garbage incineration boiler includes a housing 1, an inlet 2 is opened at the upper end of the housing 1, and an outlet is opened at one end of the housing 1 in the length direction. A conveyor belt 3 is installed inside the housing 1, and one end of the conveyor belt 3 penetrates through the outlet.

[0041] Both the inner side and the outer side of the housing 1 are rotatably connected with driving rollers 4, the two driving rollers 4 are drivingly connected through the conveyor belt 3, and any one of the driving rollers 4 is driven by a motor. Two fixed plates 6 arranged up and down are fixed inside the housing 1. The upper end of the upper fixed plate 6 is in sliding contact with the lower end of the straight part on the upper side of the conveyor belt 3, and the lower end of the lower fixed plate 6 is in sliding contact with the upper end of the straight part on the lower side of the conveyor belt 3.

[0042] As shown inFigure 2 As shown, after the garbage is put into the inlet 2 of the housing 1, the garbage falls onto the conveyor belt 3. After starting the conveyor belt 3, the garbage on the conveyor belt 3 is conveyed to the right, and the garbage enters the waste incinerator after falling from the right end of the conveyor belt 3.

[0043] As Figure 3 and Figure 5 shown, a plurality of iron bars 5 are fixedly embedded in the conveyor belt 3, and the plurality of iron bars 5 are evenly arranged along the movement track of the conveyor belt 3. The part of the conveyor belt 3 between two adjacent iron bars 5 is the area to be processed, and the plurality of iron bars 5 divide the conveyor belt 3 into a plurality of areas to be processed. The outer edge of the conveyor belt 3 between two adjacent iron bars 5 is the surface to be cleaned.

[0044] Isolation belts 7 are fixed at both ends of the conveyor belt 3 in the width direction of the housing 1. The isolation belts 7 can prevent the garbage from falling off the conveyor belt 3 when the conveyor belt 3 conveys the garbage.

[0045] A suction assembly is arranged in the housing 1 below the conveyor belt 3. The suction assembly includes a collection assembly, and an air suction hood 13 is elastically and slidably connected above the collection assembly. The air suction hood 13 is communicated with the collection assembly through a corrugated pipe 14 and a suction fan 15. The upper end of the air suction hood 13 is open, and the air suction hood 13 can slide in the height direction of the housing 1. When the suction fan 15 is started, the air in the housing 1 sequentially passes through the opening at the upper end of the air suction hood 13, the air suction hood 13, the corrugated pipe 14 and the suction fan 15 and enters the box body 16.

[0046] As Figure 6 and Figure 9 shown, the collection assembly includes a box body 16 fixed in the housing 1. A through hole is opened on one side of the box body 16, and a filter screen 32 is fixed in the through hole. A storage box 17 is slidably inserted on the other side of the box body 16. The inside of the box body 16 is communicated with the outlet end of the suction fan 15. The inlet end of the suction fan 15 is communicated with one end of the corrugated pipe 14, and the other end of the corrugated pipe 14 is fixedly communicated with the lower end of the air suction hood 13. When the air in the housing 1 passes through the opening at the upper end of the air suction hood 13, it can carry the dirt on the lower end surface of the conveyor belt 3 and sequentially pass through the air suction hood 13, the corrugated pipe 14 and the suction fan 15 and enter the box body 16. The dirt is intercepted by the filter screen 32 and falls into the storage box 17, and the air in the box body 16 is discharged through the filter screen 32. After pulling out the storage box 17 from the box body 16, the dirt in the storage box 17 can be cleaned.

[0047] As Figure 2 , Figure 6 and Figure 9 shown, a plurality of vertical fixing rods 18 are fixed at the upper end of the box body 16. The fixing rods 18 are slidably connected with the air suction hood 13. A second spring 19 is sleeved on the fixing rods 18. One end of the second spring 19 is fixedly connected with the air suction hood 13, and the other end of the second spring 19 is fixedly connected with the box body 16.

[0048] As Figure 6 and Figure 9 shown, electromagnets 20 are inlaid and fixed at both ends of the suction hood 13 in the width direction of the housing 1.

[0049] As Figure 9 shown, a scraper 21 and a magnetic force sensor 33 are respectively arranged at both ends of the suction hood 13 in the length direction of the housing 1, and the magnetic force sensor 33 is closer to the outlet of the housing 1 than the scraper 21.

[0050] As Figure 8 shown, the scraper 21 is elastically and slidably connected to the suction hood 13. Specifically, the scraper 21 can slide in the height direction of the housing 1. A vertical chute 22 is opened at the upper end of the suction hood 13. The lower end of the scraper 21 is slidably arranged in the chute 22, and the lower end of the scraper 21 is connected to the bottom of the chute 22 through a third spring 25. The upper end of the scraper 21 contacts the lower end surface of the lower flat part of the conveyor belt 3 between the two isolation belts 7.

[0051] A conductive slider 24 is fixed on the scraper 21, and a resistance strip 23 is fixed on the suction hood 13. The conductive slider 24 is electrically and slidably connected to the resistance strip 23.

[0052] As Figure 9 and Figure 10 shown, a photographing module 12 is fixed in the housing 1, and the photographing module 12 can photograph the image of the lower end surface of the conveyor belt 3 above the suction hood 13.

[0053] The magnetic force sensor 33 and the photographing module 12 are electrically connected to the controller through an image recognition module. The power supply, the current detection module, the resistance strip 23 and the conductive slider 24 form a series circuit. The current detection module, the controller, the exhaust fan 15 and the electromagnet 20 are electrically connected.

[0054] As Figure 10 shown, the width a of the inner cavity of the suction hood 13 is greater than the distance between two adjacent iron bars 5 on the flat part of the conveyor belt 3. The width a of the inner cavity of the suction hood 13 and the distance between two adjacent iron bars 5 on the flat part of the conveyor belt 3 differ by the length of one iron bar 5. The length of the electromagnet 20 is equal to the width a of the inner cavity of the suction hood 13. The contact line between the upper end of the scraper 21 and the conveyor belt 3 is flush with the inner wall of the suction hood 13 perpendicular to the length direction of the housing 1 and away from the outlet of the housing 1. When two adjacent iron bars 5 on the lower flat part of the conveyor belt 3 are located above the suction hood 13, after the magnetic force sensor 33 senses one of the iron bars 5 above the suction hood 13, it sends a signal to the controller. After receiving the signal from the magnetic force sensor 33, the controller starts the photographing module 12, and the photographing module 12 can photograph the lower end surface part of the lower flat part of the conveyor belt 3 above the suction hood 13.

[0055] As Figure 10As shown, after the conveyor belt 3 is started, the electromagnet 20 and the exhaust fan 15 are started. The electromagnet 20 can adsorb the iron bars 5 in the flat part on the lower side of the conveyor belt 3, so that the flat part on the lower side of the conveyor belt 3 is closely attached to the upper end of the scraper 21.

[0056] As Figure 10 shown, the flat part on the lower side of the conveyor belt 3 moves in the left direction. After any two adjacent iron bars 5 on the flat part on the lower side of the conveyor belt 3 are located above the air suction hood 13, when the right end of the left iron bar 5 is flush with the contact line between the upper end of the scraper 21 and the conveyor belt 3, the right end of the right iron bar 5 is flush with the right inner wall of the air suction hood 13. At this time, after the magnetic force sensor 33 senses the right iron bar 5, it sends a signal to the controller, and the controller starts the photographing module 12. The photographing module 12 takes a picture of the surface to be cleaned directly above the air suction hood 13 (the outer edge of the conveyor belt 3 between two adjacent iron bars 5 is the surface to be cleaned), and the photographing module 12 transmits the image information of the surface to be cleaned directly above the air suction hood 13 to the image recognition module for recognition, so as to judge the dirt amount of the surface to be cleaned directly above the air suction hood 13.

[0057] When the result recognized by the image recognition module is that the dirt amount of the surface to be cleaned directly above the air suction hood 13 is large, the controller starts the electromagnet 20 and increases the magnetic suction force of the electromagnet 20. After the magnetic force of the electromagnet 20 increases, the magnetic suction force of the electromagnet 20 on the iron bars 5 in the area to be processed directly above the air suction hood 13 (the part of the conveyor belt 3 between two adjacent iron bars 5 is the area to be processed, and multiple iron bars 5 divide the conveyor belt 3 into multiple areas to be processed) increases. The area to be processed directly above the air suction hood 13 can move downward and squeeze the scraper 21. After the scraper 21 is squeezed by the area to be processed directly above the air suction hood 13, the extrusion force between the scraper 21 and the conveyor belt 3 increases. After the extrusion force between the scraper 21 and the area to be processed directly above the air suction hood 13 increases, with the movement of the conveyor belt 3, the scraper 21 can ensure effective scraping of the dirt on the surface to be cleaned directly above the air suction hood 13.

[0058] After the extrusion force between the scraper 21 and the area to be processed directly above the air suction hood 13 increases, the scraper 21 moves downward in the chute 22 and squeezes the third spring 25. At the same time, the conductive slider 24 slides relative to the resistance bar 23, and the current in the series circuit composed of the power supply, the current detection module, the resistance bar 23 and the conductive slider 24 increases. Then the current detection module sends a signal to the controller, and the controller increases the power of the exhaust fan 15. That is, when the extrusion force between the area to be processed directly above the air suction hood 13 and the scraper 21 increases, the power of the exhaust fan 15 increases, which can improve the cleaning effect of the dirt on the surface to be cleaned directly above the air suction hood 13. After the area to be processed directly above the air suction hood 13 squeezes the scraper 21, the area to be processed directly above the air suction hood 13 approaches the upper port of the air suction hood 13, which can further improve the processing efficiency of the dirt on the surface to be cleaned directly above the air suction hood 13.

[0059] As the conveyor belt 3 continuously moves, the surface to be cleaned passes above the suction hood 13 in sequence. The photographing module 12 and the image recognition module analyze the amount of dirt on the surface to be cleaned in sequence. At the same time, according to the amount of dirt on the surface to be cleaned directly above the suction hood 13, the magnetic suction force of the electromagnet 20 and the power of the exhaust fan 15 are adjusted. While ensuring the effective scraping of the dirt on the surface to be cleaned, energy consumption can be saved.

[0060] Since the width a of the inner cavity of the suction hood 13 is greater than the distance between two adjacent iron bars 5 on the straight part of the conveyor belt 3, the width a of the inner cavity of the suction hood 13 and the distance between two adjacent iron bars 5 on the straight part of the conveyor belt 3 differ by the width of one iron bar 5. The length of the electromagnet 20 is equal to the width a of the inner cavity of the suction hood 13. The contact line between the upper end of the scraper 21 and the conveyor belt 3 is flush with the inner wall of the suction hood 13 that is perpendicular to the length direction of the housing 1 and away from the outlet of the housing 1. Therefore, after the controller receives the information sent by the image recognition module and adjusts the magnetic suction force of the electromagnet 20 and the power of the exhaust fan 15, during the process of the scraper 21 scraping the dirt on the surface to be cleaned above the suction hood 13, the photographing module 12 does not take pictures, and the magnetic suction force of the electromagnet 20 remains unchanged, that is, the extrusion force between the scraper 21 and the area to be processed directly above the suction hood 13 remains unchanged. The power of the exhaust fan 15 also remains unchanged. When the entire surface to be cleaned directly above the suction hood 13 passes above the upper end of the scraper 21, the magnetic force sensor 33 will sense the subsequent iron bar 5, and the photographing module 12 will start working. In this embodiment, not only can the amount of dirt on multiple surfaces to be cleaned be analyzed in sequence, but during the process of the scraper 21 scraping the dirt on one surface to be cleaned, it can be ensured that the extrusion force between the scraper 21 and the area to be processed directly above the suction hood 13 remains unchanged, and the power of the exhaust fan 15 remains unchanged, which can ensure the scraping effect of the dirt on the surface to be cleaned.

[0061] When the result recognized by the image recognition module is that the amount of dirt on the surface to be cleaned directly above the suction hood 13 is small, the power of the exhaust fan 15 remains unchanged, and the magnetic suction force of the electromagnet 20 remains unchanged.

[0062] Embodiment 2: On the basis of Embodiment 1, as Figure 2 and Figure 5 shown, a cleaning assembly and a scraping assembly are arranged in the housing 1 below the conveyor belt 3, the suction assembly is located between the cleaning assembly and the scraping assembly, and the cleaning assembly is farther from the outlet of the housing 1 than the scraping assembly.

[0063] As Figure 2 、 Figure 5 and Figure 6As shown, the shoveling component includes a collection box 8 fixed inside the housing 1. On the upper side of one end of the collection box 8 away from the outlet of the housing 1 in the length direction of the housing 1, an inclined sliding cavity 9 is formed. A shovel plate 10 is slidably arranged in the sliding cavity 9. The upper end of the shovel plate 10 contacts the lower end face of the lower flat part of the conveyor belt 3 between the two isolation belts 7. A first spring 11 is arranged in the sliding cavity 9. One end of the first spring 11 is fixedly connected to the shovel plate 10, and the other end of the first spring 11 is fixedly connected to the collection box 8.

[0064] When the flat part on the lower side of the conveyor belt 3 moves in the left direction, the shovel plate 10 can shovel the garbage adhered to the lower end of the lower flat part of the conveyor belt 3, and the shoveled garbage enters the collection box 8.

[0065] As Figure 2 、 Figure 5 and Figure 11 shown, the cleaning component includes a lifting plate 29. A cleaning sponge 30 is fixed to the upper end of the lifting plate 29. The upper end of the cleaning sponge 30 contacts the lower end face of the lower flat part of the conveyor belt 3 between the two isolation belts 7. Two connecting plates 26 are fixed inside the housing 1 below the conveyor belt 3 along the length direction of the housing 1. The connecting plates 26 are arranged vertically. The lifting plate 29 and the cleaning sponge 30 are located between the two connecting plates 26. A plurality of vertical spring telescopic rods 28 are arranged below the lifting plate 29.
