Description

Technical Field

[0001] This invention relates to the field of waste cleaning technology, and in particular to a prefabricated pump station mechanical conveying waste cleaning device. Background Technology

[0002] A prefabricated pumping station is usually installed at the drainage outlet or sump of a garbage station. The submersible sewage pumps in the pumping station lift and transport the leachate and sludge-containing sewage generated by the garbage station to the municipal sewage network. However, the sewage from garbage stations is complex in composition, containing a large amount of solid pollutants such as household waste debris, fibrous debris (such as plastic bags, strips of cloth, ropes, hair, etc.), food scraps, silt, and highly viscous organic matter. To prevent these debris from entering the pumping station and clogging the pump impeller, entangling the submersible pump, or blocking the pumping station's outlet pipe, a rotary bar screen is usually installed at the inlet of the prefabricated pumping station. Through the continuous operation of its rotating bar chain, garbage debris in the sewage is intercepted and transported upward along the bar surface to the sludge discharge port, thereby achieving pretreatment of the sewage entering the pumping station.

[0003] For example, Chinese patent CN120324971B discloses a bar screen cleaner for sewage treatment. By setting up cleaning blocks and movable support plates, the support plates can rotate in a vertical position, which facilitates the separation of pollutants and prevents pollutants from accumulating in the inclined bar screen. At the same time, the vertical position of the support plates makes it easy for the cleaning blocks to move up and down for cleaning, further improving the cleaning effect on the support plates and separation plates, reducing the difficulty of cleaning the support plates and separation plates, and effectively ensuring the separation effect of the bar screen chain and pollutants.

[0004] Given the aforementioned existing technology, although setting up a cleaning block and a movable support plate can achieve a certain cleaning effect on the stripper plate and the separator plate, and ensure the separation effect between the grid chain and the contaminants, the working logic of the cleaning block in this existing technology is that the grid chain advances one link, the driving cam rotates one revolution, and the cleaning block moves up and down once. Therefore, the grid chain operates intermittently, advancing only one link at a time. The contaminants fall continuously due to gravity the moment the support plate loses its limit. During the interval between the cleaning block's up and down brushing, the contaminants have already accumulated on the support plate. When the cleaning block comes down to brush again, the accumulated contaminants have been compacted and adhered, making it difficult for the cleaning block to effectively remove the contaminants and reducing the cleaning efficiency.

[0005] Therefore, the present invention provides a prefabricated pump station mechanical conveying garbage cleaning device to meet the requirements. Summary of the Invention

[0006] The technical problem to be solved by this invention is to provide a prefabricated pump station mechanical conveying garbage cleaning device. By setting a cleaning component that rotates synchronously with the rake tooth chain, it can continuously clean the surface dirt of the rake tooth chain during continuous operation without waiting for intermittent stops, thereby avoiding the problem of pollutants accumulating and compacting on the surface of the rake tooth chain, ensuring the stability and continuity of the cleaning effect. While cleaning the dirt on the surface of the rake tooth chain, the cleaning component can also achieve self-cleaning, reducing the maintenance frequency. At the same time, it can also play a role in assisting the straightening of the rake tooth tips. Through the above settings, the problem of pollutants accumulating easily and reducing cleaning efficiency caused by intermittent cleaning of cleaning blocks in the prior art can be solved.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A prefabricated pump station mechanical conveying garbage cleaning device includes a pump body, a frame at the top of the pump body, a rake tooth chain rotatably mounted inside the frame, and a water collection tank on one side of the bottom of the frame; and a cleaning component for cleaning the rake tooth chain, the cleaning component being connected to the frame and the rake tooth chain respectively.

[0008] Optionally, the cleaning assembly includes a rotating shaft that rotates between the inner walls of the frame. The rotating shaft rotates synchronously with the rake tooth chain. The rotating shaft is located below the horizontal section of the rake tooth chain. The rotating shaft surface is provided with multiple brush plates circumferentially. Each pair of adjacent brush plates is provided with a straightening frame. The rake tooth chain is in clearance fit with the brush plates and the straightening frames.

[0009] Optionally, the rotating shaft surface is provided with a circumferentially oriented actuation groove, the actuation groove corresponding to the brush plate, the bottom of the brush plate swinging within the actuation groove by a torsion spring, and a connecting plate is provided between two adjacent brush plates, the connecting plate being located below the orthopedic frame, and the connecting plate covering the actuation groove.

[0010] Optionally, the orthotic frame includes an orthotic part, which is fixed to the movable end of the brush plate. An arc-shaped part is provided on one side of the orthotic part, and a guide part is provided at the end of the arc-shaped part away from the orthotic part. The orthotic part and the guide part are respectively connected to two adjacent brush plates, and the guide part is slidably connected to the brush plate.

[0011] Optionally, the movable end of the brush plate is provided with an inclined surface, and the cross-section of two adjacent inclined surfaces is V-shaped.

[0012] Optionally, a drive gear is rotatably provided between the inner walls of the frame, the drive gear meshes with the rake tooth chain, a connecting pipe is provided between the horizontal sections on the inner side of the rake tooth chain, a plurality of nozzles are provided at equal intervals on the connecting pipe, a flushing pipe is provided at one end of the connecting pipe, the other end of the flushing pipe extends into the pump body, and the connecting pipe is located above the rotating shaft and the brush plate.

[0013] Optionally, a support cylinder is provided between the inner walls of the frame, the connecting pipe rotates inside the support cylinder, a connecting sleeve is provided between the connecting pipe and the flushing pipe, the connecting sleeve is fixed to one end of the connecting pipe, the connecting sleeve is rotatably connected to the flushing pipe, and a swinging part is provided on one side of the connecting sleeve, the swinging part meshing with the drive gear.

[0014] Optionally, one end of the support cylinder is provided with a support portion, one end of the flushing pipe passes through the support portion and is rotatably connected to the connecting sleeve, and the end of the support portion away from the support cylinder is connected to the inner wall of the frame.

[0015] Optionally, the surface of the support cylinder is provided with a plurality of guide ports at equal intervals, the number of guide ports corresponding to the number of nozzles, and the nozzles can slide within the guide ports.

[0016] Optionally, a baffle is provided on one side of the support cylinder, and the nozzle is located below the baffle.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a cleaning component that rotates synchronously with the rake chain, the surface dirt of the rake chain can be continuously cleaned during its continuous operation without waiting for intermittent stops. This avoids the problem of contaminants accumulating and compacting on the surface of the rake chain, ensuring the stability and continuity of the cleaning effect. While cleaning the dirt on the surface of the rake chain, the cleaning component can also achieve self-cleaning, which helps to avoid the problem of cleaning component failure or jamming due to dirt adhesion, thereby reducing the maintenance frequency. At the same time, when the cleaning component contacts the rake tooth tips of the rake chain, it can play an auxiliary orthopedic role in the rake tooth tips, which can help correct deformed rake tooth tips during the cleaning process. This helps to avoid the problem of increased interception gap and reduced dirt removal efficiency caused by rake tooth deformation, thus effectively ensuring the dirt removal performance and service life of the rake chain.

[0018] By setting up a brush plate and a corrective frame, the brush plate can perform reverse brushing on the rake chain. The reverse brushing creates a relative speed superposition between the brush teeth of the brush plate and the rake teeth of the rake chain, thereby increasing the brushing force and making it easier to remove contaminants. The brush plate rotates synchronously with the rake chain, enabling continuous cleaning of surface dirt during the continuous operation of the rake chain without waiting for intermittent stops. When the rake tooth tips pass through the corrective frame, the corrective frame increases the contact area with the rake tooth tips. Each time the rake tooth tips pass through the corrective frame, they are subjected to a corrective force, which can thus play an auxiliary corrective role for the rake tooth tips.

[0019] By setting up a toggle groove in conjunction with the brush plate and torsion spring, when the brush teeth pass between the rake teeth of the rake chain, the swingable brush plate can play a certain buffering role, which helps to extend the service life of the brush plate. At the same time, when the brush plate passes through a set of rake teeth, it automatically resets under the action of the torsion spring. When resetting, the brush plate contacts the side wall of the toggle groove 8 and generates a vibration effect, which effectively reduces the adhesion of impurities on the brush plate itself, thereby achieving self-cleaning of the brush plate and reducing maintenance costs.

[0020] By setting up a corrective part, an arc-shaped part, and a guide part, the corrective part increases the contact area with the tip of the rake teeth, thus playing an auxiliary corrective role. When the brush plate swings to one side of the actuation groove, it pushes the arc-shaped part to drive the guide part to slide along the height direction of the slide plate onto the adjacent brush plate, so that the guide part can clean the gap between the brush teeth of the adjacent brush plates, further ensuring the cleaning effect of the brush plate.

[0021] By setting up a connecting pipe, nozzle, connecting sleeve, and swinging part, the connecting sleeve and connecting pipe are driven to swing back and forth under the action of a torsion spring, thereby realizing the swinging spray of the nozzle, increasing the coverage of the nozzle spray, and further improving the cleaning efficiency.

[0031] Example 1 like Figures 1 to 9As shown, an embodiment of the present invention provides a prefabricated pumping station mechanical conveying garbage cleaning device, including a pump body 1. The pump body 1 is a mature integrated prefabricated pumping station in the prior art, which is pre-buried underground during use. A frame 2 is provided on the top of the pump body 1. A part of the frame 2 extends into the pump body 1, and the other part of the frame 2 is located outside the pump body 1. In order to ensure the operational stability of the frame 2, a support frame is also provided on the part of the frame 2 located outside the pump body 1. The support frame is fixed between the frame 2 and the ground, providing stable support for the frame 2. The frame 2 rotates... The machine is equipped with a rake chain 3, and a water collection trough 4 is located on one side of the bottom of the frame 2. Driven by a motor, the rake chain 3 rotates within the frame 2 guided by a guide rail. The specific installation method is disclosed as prior art and will not be elaborated upon here. A crushing grid is installed at the inlet of the pump body 1 to initially crush impurities entering the pump body 1. The water collection trough 4 is connected to the outlet side of the crushing grid, facilitating the concentration of waste and impurities entering the pump body 1 within the reach of the rake chain 3. In use, the rake chain 3 is driven by a motor to rotate along the path of the guide rail. Inside the frame 2, the garbage and impurities collected in the water collection tank 4 are transported to the slag discharge port on one side of the frame 2, completing the garbage cleaning inside the pump body 1. The cleaning component is used to clean the rake tooth chain 3. The cleaning component is connected to both the frame 2 and the rake tooth chain 3. The cleaning component rotates synchronously with the rake tooth chain 3, and can continuously clean the surface dirt of the rake tooth chain 3 during continuous operation without waiting for intermittent stops. This avoids the problem of pollutants accumulating and compacting on the surface of the rake tooth chain 3, ensuring the stability and continuity of the cleaning effect. While cleaning the surface dirt of the rake tooth chain 3, the cleaning component can also achieve self-cleaning, which helps to avoid the problem of the cleaning component being stuck by dirt, resulting in cleaning failure or jamming, thereby reducing the maintenance frequency. At the same time, when the cleaning component contacts the rake tooth tips of the rake tooth chain 3, it can play an auxiliary corrective role for the rake tooth tips, which can help correct deformed rake tooth tips during the cleaning process. This helps to avoid the problem of increased interception gap and reduced dirt removal efficiency caused by rake tooth deformation, thereby effectively ensuring the dirt removal performance and service life of the rake tooth chain 3.

[0032] As one implementation method in this embodiment, such as Figures 3 to 9As shown, the cleaning assembly includes a rotating shaft 5, which rotates between the inner walls of the frame 2. The rotating shaft 5 rotates synchronously with the rake chain 3. It can be understood that the rotating shaft 5 and the rake chain 3 are connected by an existing transmission mechanism to achieve synchronous rotation. As an example, it can be a mechanism that uses a synchronous pulley and a synchronous belt. It is not specifically limited to achieving the effect of synchronous rotation, and will not be elaborated on here. The rotating shaft 5 is located below the horizontal section of the rake chain 3. Multiple brush plates 6 are circumferentially arranged on the surface of the rotating shaft 5. Each pair of adjacent brush plates 6 is provided with a straightening frame 7. The rake chain 3 is clearance-fitted with the brush plates 6 and the straightening frame 7. Driven by the motor, the rotation of the rake chain 3 can synchronously drive the rotating shaft 5 and its brush plates 6 and straightening frame 7 to rotate synchronously. The brush teeth on the brush plates 6 can pass between adjacent rake teeth on the rake chain 3. Since the rotating shaft 5 is located below the horizontal section of the rake chain 3, that is, the brush plates 6 and the straightening frame 7 are also located below the horizontal section of the rake chain 3, under the guidance of the guide rail, the rotation direction of the brush plates 6 is the same as the movement direction of the horizontal section of the rake chain 3 located below. The opposite direction of the brush plate 6 causes the brush plate 6 to brush the rake chain 3 in a reverse direction. This reverse brushing creates a relative speed superposition between the brush teeth of the brush plate 6 and the rake teeth of the rake chain 3, thereby increasing the brushing force and making it easier to remove contaminants. As the brush plate 6 rotates synchronously with the shaft 5 and the rake chain 3, it can continuously clean the surface dirt of the rake chain 3 during its continuous operation without waiting for intermittent stops. This avoids the problem of contaminants accumulating and compacting on the surface of the rake chain 3, ensuring the stability and continuity of the cleaning effect. When the rake tooth tips of the rake chain 3 pass through the straightening frame 7, the straightening frame 7 increases the contact area with the rake tooth tips. Each time the rake tooth tips pass through the straightening frame 7, they are subjected to a corrective force, which can play an auxiliary corrective role for the rake tooth tips. Slight deformation is gradually corrected before it develops into severe deformation, thus effectively avoiding the problem of increased interception gap and reduced decontamination efficiency caused by the accumulation of slight deformation. This effectively ensures the decontamination performance and service life of the rake chain 3.

[0033] It should be noted that in order to ensure the cleaning effect of the brush plate 6, the speed ratio of the rake tooth chain 3 and the rotating shaft 5 can be changed. The method of changing the speed ratio is a mature existing technology, which will not be elaborated on here.

[0034] In this embodiment, as Figure 4 and Figure 7As shown, the rotating shaft 5 has a circumferentially oriented actuation groove 8, which corresponds to the brush plate 6. The bottom of the brush plate 6 swings within the actuation groove 8 via a torsion spring. When the rake tooth chain 3 transports garbage, some garbage and impurities do not fall off naturally due to gravity, but instead become entangled on the tips of the rake teeth. When the brush plate 6 passes between the rake teeth of the rake tooth chain 3, the relative movement between the brush teeth of the brush plate 6 and the rake teeth can clean off the entangled garbage and impurities. The bottom of the brush plate 6 is oscillatingly positioned within the actuation groove 8 via a torsion spring. When the brush teeth of the brush plate 6 pass between the rake teeth of the rake tooth chain 3, the oscillating brush plate 6 can provide a certain buffering effect, which helps to extend the service life of the brush plate 6. At the same time, when the brush plate 6 passes through a set of rake teeth, it automatically resets under the action of the torsion spring. During the reset, the brush plate 6 contacts the side wall of the actuation groove 8 and generates a vibration effect, which effectively reduces the adhesion of impurities on the brush plate 6 itself, thereby achieving self-cleaning of the brush plate 6 and reducing maintenance costs.

[0035] In this embodiment, as Figures 4 to 7 As shown, a connecting plate 9 is provided between two adjacent brush plates 6. The connecting plate 9 is located below the orthopedic frame 7. The connecting plate 9 can cover the agitator groove 8. The connecting plate 9 plays a certain covering role in the agitator groove 8, effectively preventing foreign objects from falling into the agitator groove 8 and avoiding the brush plate 6 from being obstructed due to impurities stuck in the groove. This ensures the reliability of the brush plate 6 operation. The connecting plate 9 is made of flexible material. During the swing of the brush plate 6, the connecting plate 9 can adapt to the movement of the brush plate 6 and will not interfere with the normal swing of the brush plate 6. This ensures the covering function without affecting the cleaning action of the brush plate 6. At the same time, the surface of the connecting plate 9 is a smooth arc shape. When dirt and impurities pass by, the arc shape can guide the dirt and impurities, allowing them to slide smoothly down the arc shape, thus improving the cleaning efficiency.

[0036] In this embodiment, as Figures 6 to 9 As shown, the orthotic frame 7 includes an orthotic part 11, which is fixed to the movable end of the brush plate 6. An arc-shaped part 12 is provided on one side of the orthotic part 11, and a guide part 13 is provided at the end of the arc-shaped part 12 away from the orthotic part 11. The orthotic part 11 and the guide part 13 are respectively connected to two adjacent brush plates 6. The guide part 13 is slidably connected to the brush plate 6. The orthotic part 11 is fixed to the movable end of the brush plate 6. When the tip of the rake tooth of the rake tooth chain 3 passes through the orthotic part 11, the orthotic part 11 increases the contact area with the tip of the rake tooth, thereby playing an auxiliary orthotic role. When the brush plate 6 swings towards the actuating groove 8, it pushes the arc-shaped part 12 to drive the guide part 13 to slide along the height direction of the slide plate 6 on the adjacent brush plate 6, so that the guide part 13 can clean the gap between the brush teeth of the adjacent brush plate 6, further ensuring the cleaning function of the brush plate 6.

[0037] In this embodiment, as Figure 7 and Figure 8As shown, the movable end of the brush plate 6 is provided with an inclined surface 10. The cross-section of two adjacent inclined surfaces 10 is V-shaped, that is, two adjacent inclined surfaces 10 form a V-shaped opening. This allows the tips of the rake teeth of the rake tooth chain 3 to have a slight angular deviation when they come into contact with the brush teeth of the brush plate 6. The V-shaped inclined surface can automatically guide them to the center position of the gap between the brush teeth of the brush plate 6, achieving a self-alignment effect and improving the smoothness and reliability of the auxiliary orthodontic treatment.

[0038] Example 2 In this embodiment, as Figures 10 to 12 As shown, a drive gear 23 is rotatably mounted between the inner walls of the frame 2. The drive gear 23 meshes with the rake tooth chain 3. As mentioned above, the drive gear 23 can be part of the aforementioned transmission mechanism. Its function is to drive the rake tooth chain 3 to rotate along the guide rail under the drive of the motor. A connecting pipe 19 is provided between the horizontal sections on the inner side of the rake tooth chain 3. Multiple nozzles 16 are equidistantly mounted on the connecting pipe 19. A flushing pipe 15 is provided at one end of the connecting pipe 19, and the other end of the flushing pipe 15 extends into the pump body 1. The connecting pipe 19 is located above the rotating shaft 5 and the brush plate 6, for flushing... A suction pump is provided at one end of the pipe 15 extending into the pump body 1 to provide flushing water flow to the connecting pipe 19. The flushing pipe 15 is fixed to one side of the inner wall of the frame 2 by a clamp, so as not to interfere with the operation of the rake tooth chain 3. The nozzle 16 is a high-pressure nozzle. The connecting pipe 19 is located above the rotating shaft 5 and the brush plate 6. When the brush plate 6 is cleaning, the flushing with high-pressure water flow can further improve the cleaning efficiency. At the same time, the flushing water flow can slide smoothly down the smooth surface of the connecting part 9, which can further clean the brush plate 6 itself.

[0039] It should be noted that, in order to ensure the flushing effect on the rake tooth chain 3 and the brush plate 6, one end of the connecting pipe 19 can also pass through the pump body 1 and be connected to an external water source. This can be selected according to specific needs, and no specific limitation is made here.

[0040] In this embodiment, as Figures 10 to 12As shown, a support cylinder 14 is provided between the inner walls of the frame 2. The connecting pipe 19 rotates inside the support cylinder 14. A connecting sleeve 18 is provided between the connecting pipe 19 and the flushing pipe 15. The connecting sleeve 18 is fixed to one end of the connecting pipe 19 and is rotatably connected to the flushing pipe 15. A swinging part 17 is provided on one side of the connecting sleeve 18. The swinging part 17 meshes with the drive gear 23. The support cylinder 14 supports the connecting pipe 19. The connecting sleeve 18 connects the connecting pipe 19 and the flushing pipe 15. The connecting pipe 19 rotates inside the support cylinder 14 through a torsion spring. The swinging part 17 meshes with the drive gear 23 on one side of the connecting sleeve 18. When the drive gear 23 rotates, it drives the swinging part 17 to push and slide alternately. Under the action of the torsion spring, it drives the connecting sleeve 18 and the connecting pipe 19 to swing back and forth, thereby realizing the swinging spray of the nozzle 16, increasing the coverage of the nozzle 16 and improving the cleaning efficiency. The cooperation between the swinging part 17 and the torsion spring and the drive gear 23 can be referred to as the cooperation principle of the pawl and the ratchet.

[0041] In this embodiment, as Figures 10 to 12 As shown, one end of the support cylinder 14 is provided with a support part 20, and one end of the flushing pipe 15 passes through the support part 20 and is rotatably connected to the connecting sleeve 18. The end of the support part 20 away from the support cylinder 14 is connected to the inner wall of the frame 2. The support part 20 provides additional support and anchoring for the connection point of the connecting sleeve 18 and the flushing pipe 15, so that the connecting sleeve 18 will not be separated from the axis of the support cylinder 14 due to excessive torque during the swing, thus ensuring the coaxiality and stability of the swing. At the same time, the flushing pipe 15 passes through the support part 20 and is rotatably connected to the connecting sleeve 18, which means that the flushing pipe 15 and the connecting pipe 19 have achieved complete motion decoupling. The fixed flushing pipe 15 will not be subjected to any torsional or pulling force due to the swing of the connecting pipe 19.

[0042] In this embodiment, as Figure 11 and Figure 12 As shown, the surface of the support cylinder 14 is provided with a plurality of guide ports 21 at equal intervals. The number of guide ports 21 corresponds to the number of nozzles 16. The nozzles 16 can slide in the guide ports 21. When the nozzles 16 swing with the connecting pipe 19, the guide ports 21 provide an independent sliding track for each nozzle 16, providing guidance for the swing of the nozzles 16.

[0043] In this embodiment, as Figures 10 to 12 As shown, a baffle 22 is provided on one side of the support cylinder 14, and the nozzle 16 is located below the baffle 22. The baffle 22 acts as a physical shield, which not only prevents impurities on the horizontal section of the rake chain 3 above from falling and interfering with the operation of the nozzle 16, but also allows the water jet from the nozzle 16 to fully act on the horizontal section of the rake chain 3 below and the brush plate 6. At the same time, the baffle 22 can also prevent high-pressure water from directly impacting the upper part of the support cylinder 14, and avoid water flow from causing erosion and corrosion to the transmission mechanism.

[0044] The working principle of the technical solution provided by this invention is as follows: In use, the motor drives the drive gear 23 to continuously rotate the rake chain 3 along the guide rail, transporting the garbage and impurities collected in the water collection tank 4 to the slag discharge port on one side of the frame 2, thus completing the garbage cleaning inside the pump body 1. When the rake chain 3 rotates, under the transmission action of the transmission mechanism, the rotating shaft 5 and its brush plate 6 and straightening frame 7 rotate synchronously. The brush teeth on the brush plate 6 can pass between adjacent rake teeth on the rake chain 3. Since the brush plate 6 and the straightening frame 7 are located below the horizontal section of the rake chain 3, under the guidance of the guide rail, the rotation direction of the brush plate 6 is the same as that of the rake chain 3 located below. The horizontal section operates in the opposite direction. When the brush plate 6 passes between the rake teeth of the rake chain 3, the relative movement between the brush teeth of the brush plate 6 and the rake teeth can clean off the tangled debris. The bottom of the brush plate 6 is oscillatingly set in the actuating groove 8 by a torsion spring. When the brush teeth of the brush plate 6 pass between the rake teeth of the rake chain 3, the oscillating brush plate 6 can play a certain buffering role, which helps to extend the service life of the brush plate 6. At the same time, when the brush plate 6 passes through a set of rake teeth, it automatically resets under the action of the torsion spring. When resetting, the brush plate 6 contacts the side wall of the actuating groove 8 and generates... The vibration effectively reduces the adhesion of impurities to the brush plate 6 itself, thereby achieving self-cleaning of the brush plate 6. When the tips of the rake teeth of the rake chain 3 pass through the corrective part 11 of the corrective frame 7, the corrective part 11 increases the contact area with the tips of the rake teeth, thus playing an auxiliary corrective role. When the brush plate 6 passes between the rake teeth of the rake chain 3, under the obstruction of debris and impurities, it will push the brush plate 6 to swing towards the actuating groove 8. At this time, the corrective part 11 will push the arc-shaped part 12 to drive the guide part 13 to slide along the height direction of the slide plate 6 onto the adjacent brush plate 6, so that the guide part 13 can... The brush tooth gaps between adjacent brush plates 6 are cleaned, further ensuring the cleaning effect of brush plates 6. When the rake tooth chain 3 rotates, the suction pump is activated to flush water through the flushing pipe 15 to the connecting pipe 19, and high-pressure water is sprayed through the nozzle 16 to wash the rake tooth chain 3 and brush plates 6. Meanwhile, the drive gear 23 drives the swing part 17 to alternately push and slide, and under the action of the torsion spring, it drives the connecting sleeve 18 and the connecting pipe 19 to swing back and forth, thereby realizing the swing spray of the nozzle 16, increasing the coverage of the spray of the nozzle 16 and improving the cleaning efficiency.
