Abstract
Description
Technical Field
[0001] This invention relates to the field of garbage truck technology, specifically to a drip-proof structure and a garbage truck. Background Technology
[0002] With the acceleration of urbanization in my country, the amount of domestic waste is increasing daily. Compactor garbage trucks, due to their convenient loading function and powerful compression capacity, have rapidly become the main vehicle type for garbage collection and transportation. The compactor of a compactor garbage truck is sealed to the truck body with a sealing strip, but this sealing strip gradually ages and fails over time. At the same time, foreign objects can easily get trapped on the contact surface of the sealing strip, leading to a poor seal. During garbage transportation, as the vehicle bounces, wastewater inside the truck body can easily leak out from the sealing strip.
[0003] Currently, to prevent sewage from leaking out, sewage troughs and tanks are usually installed at the connection between the truck body and the loader. The sewage trough and tank are connected to collect sewage. However, in the actual process of transporting garbage, small pieces of garbage such as branches, leaves, gravel, sand and mud may leak from the sealing strips. As these small pieces of garbage accumulate in the sewage trough, they can block the guide holes in the sewage trough, causing sewage to flow out of the sewage trough instead of entering the sewage tank. Therefore, the sewage collection structure of existing garbage trucks still has the problem of poor reliability. Summary of the Invention
[0004] In view of this, the present invention provides a drip-proof structure and a garbage truck to solve the problem of poor reliability of the sewage collection structure of existing garbage trucks.
[0005] In a first aspect, the present invention provides an anti-drip device for use in a garbage truck, the garbage truck including a filler and a truck body, comprising: a sewage guiding structure having a guiding channel for sewage to flow in, the sewage guiding structure being adapted to be fixedly installed in the filler, the sewage guiding structure extending along the width direction of the filler, and the sewage guiding structure being located below the connection position between the filler and the truck body; a storage structure adapted to be installed in the filler and connected to the sewage guiding structure, the storage structure having a receiving cavity for receiving sewage, the receiving cavity communicating with the guiding channel; and a cleaning component installed on one side of the sewage guiding structure, the cleaning component having a cleaning state for cleaning the guiding channel and a stopping state for stopping operation.
[0006] Beneficial effects: The sewage guiding structure extends along the width of the compactor, and a cleaning component is installed on one side of the sewage guiding structure. The sewage guiding structure can effectively receive sewage leaking from the connection point, and the cleaning component can regularly and actively clean the guiding channel of the sewage guiding structure, ensuring the sewage collection effect while keeping the guiding channel unobstructed. This effectively solves the problem of poor reliability of the sewage collection structure of existing garbage trucks.
[0007] In one alternative embodiment, the connection between the filler and the vehicle body forms a leak location, and the sewage guiding structure includes a guide channel with its opening facing the leak location. The length of the guide channel is greater than the length of the leak location, and the internal space of the guide channel forms a guiding channel.
[0008] Beneficial effects: The guide channel has a large opening and can cover the leakage point, thus further improving the sewage collection effect.
[0009] In one alternative embodiment, the cleaning component includes a purging structure and an air supply delivery structure, the purging structure being disposed on the side of the guide trough near the loader, and the air supply delivery structure being adapted to be disposed on the body of the garbage truck.
[0010] Beneficial effects: The blowing structure can actively blow the guide channel, and it can be effectively applied to various types of waste, whether dry or wet. The cleaning process is simple, quick, and the cleaning effect is better.
[0011] In one optional embodiment, the purging structure extends along the length of the guide groove, and a plurality of purging nozzles are provided on the side of the purging structure near the guide groove, with the plurality of purging nozzles spaced apart along the extension direction of the purging structure.
[0012] Beneficial effects: Multiple purging nozzles can effectively cover the guide groove, ensuring cleaning results.
[0013] In one optional embodiment, the air supply structure includes a purge switch, a main air source, and a secondary air source. One side of the purge switch is connected to both the main air source and the secondary air source, and the other side of the purge switch is connected to the purge structure. The main air source is suitable for supplying air when the garbage truck is in the start-up state, and the secondary air source is suitable for supplying air when the garbage truck is in the off state.
[0014] Beneficial effects: Both the main and auxiliary air sources can supply air to the purging structure, ensuring a sufficient air supply, and purging can be carried out regardless of whether the garbage truck is running or not.
[0015] In one alternative implementation, the main air source is the air compressor on the garbage truck, and the secondary air source is the air storage structure.
[0016] Beneficial effects: The purging structure can be directly supplied with air by the air compressor and air storage structure on the garbage truck. There is no need to set up an additional air source or add other power units. The air storage structure can still supply air when the garbage truck is turned off. This makes the overall cleaning component less complex and simpler, and also greatly reduces the difficulty of manufacturing and installation.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.
[0032] According to an embodiment of the present invention, in one aspect, an anti-drip device is provided for use in a garbage truck. The garbage truck includes a filler 4 and a truck body. The anti-drip device includes a sewage guiding structure, a storage structure, and a cleaning component. The sewage guiding structure has a guiding channel for sewage to flow in. The sewage guiding structure is adapted to be fixedly installed in the filler 4 and extends along the width direction of the filler 4. The sewage guiding structure is located below the connection position between the filler 4 and the truck body. The storage structure is adapted to be installed in the filler 4 and connected to the sewage guiding structure. The storage structure has a receiving cavity for receiving sewage, and the receiving cavity communicates with the guiding channel. The cleaning component is installed on one side of the sewage guiding structure and has a cleaning state for cleaning the guiding channel and a stopping state for stopping operation.
[0033] The anti-drip device of this embodiment extends the sewage guiding structure along the width of the filler 4. At the same time, a cleaning component is provided on one side of the sewage guiding structure. The sewage guiding structure can effectively receive sewage leaking from the connection position. The cleaning component can periodically and actively clean the guiding channel of the sewage guiding structure, ensuring the sewage collection effect while keeping the guiding channel unobstructed. This effectively solves the problem of poor reliability of the sewage collection structure of existing garbage trucks.
[0034] Among them, the width direction of the filler 4 refers to Figure 1 The direction indicated by the middle arrow is "left" or "right".
[0035] It should be noted that there is no limit to the specific size of the sewage guiding structure. It can be selected according to the sewage leakage situation, as long as it can reliably collect sewage and prevent dripping.
[0036] In this embodiment, the connection between the filler 4 and the vehicle body forms a leak position. The sewage guiding structure includes a guide channel 101. The opening of the guide channel 101 faces the leak position. The length of the guide channel 101 is greater than the length of the leak position. The internal space of the guide channel 101 forms a guiding channel. The opening of the guide channel 101 is large and can cover the leak position, thus further improving the sewage collection effect.
[0037] Specifically, the structure of the guide trough 101 is not limited; it can be a rectangular trough, an inverted trapezoidal trough, an arc-shaped trough, etc., as long as it can reliably collect sewage.
[0038] In related technologies, due to structural limitations of the filler 4, smaller guide grooves are usually set on both sides of the filler 4 to collect sewage that leaks from both sides of the connection between the filler 4 and the vehicle body. However, this type of guide groove cannot effectively collect all the sewage that leaks from the connection, especially at the bottom of the connection.
[0039] In this embodiment, the length of the guide groove 101 is greater than the length of the leak position, which can reliably and effectively cover the leak position and prevent sewage from dripping onto the road.
[0040] It should be noted that the length of the leakage position is the width of the connection between the filler 4 and the vehicle body, or the length of the sealing strip extending along the width direction of the connection position.
[0041] In this embodiment, the cleaning component includes a blowing structure 201 and an air supply conveying structure. The blowing structure 201 is disposed on the side of the guide trough 101 near the loader 4, and the air supply conveying structure is suitable for being disposed on the body of the garbage truck. The blowing structure 201 can actively blow the guide trough 101. At the same time, the blowing structure 201 can be effectively applied to various types of garbage, whether it is dry garbage or wet garbage, and can effectively blow it. The cleaning process is simple and quick and the cleaning effect is better.
[0042] In related technologies, in order to clean the guide trough 101 during garbage truck operation, some systems install a swingable scraper at the opening of the guide trough 101. When the loader 4 swings and lifts away from the truck body, the scraper moves along the inner wall of the guide trough 101 due to its own weight, thereby achieving the effect of cleaning the guide trough. This method can only clean the guide trough when the loader 4 is driven to lift, making the cleaning process very troublesome. At the same time, since this method is a mechanical passive cleaning, the scraper and the arc-shaped guide trough are manufactured with high precision requirements, which inevitably results in gaps between the scraper and the guide trough. Therefore, small garbage at the bottom of the guide trough still cannot be cleaned. Over time, this will jam the scraper, preventing it from swinging and causing it to malfunction. Small garbage will continue to accumulate in subsequent operations. Meanwhile, the scraper's own weight has limited impact during the lifting of the loader 4, making it less effective at cleaning wet garbage such as branches and leaves.
[0043] The cleaning component in this embodiment is an active blowing structure 201, which can actively clean without needing to be connected to the guide groove 101, thus improving cleaning flexibility and eliminating cleaning dead corners.
[0044] In this embodiment, the blowing structure 201 extends along the length of the guide groove 101. A plurality of blowing nozzles 202 are provided on the side of the blowing structure 201 near the guide groove 101. The plurality of blowing nozzles 202 are spaced apart along the extension direction of the blowing structure 201. The plurality of blowing nozzles 202 can effectively cover the guide groove 101 to ensure the cleaning effect.
[0045] Specifically, there are no restrictions on the type and structure of the purging nozzle 202; existing high-pressure nozzles can be referenced. There are no strict restrictions on the number and spacing of the purging nozzle 202; they can be set according to the actual length of the guide groove 101 and the required purging intensity.
[0046] In this embodiment, the air supply structure includes a purge switch 203, a main air source 204, and a secondary air source 205. One side of the purge switch 203 is connected to both the main air source 204 and the secondary air source 205, and the other side of the purge switch 203 is connected to the purge structure 201. The main air source 204 is suitable for supplying air when the garbage truck is in the running state, and the secondary air source 205 is suitable for supplying air when the garbage truck is in the off state. Both the main air source 204 and the secondary air source 205 can supply air to the purge structure 201, ensuring a sufficient air supply. Purge can be performed regardless of whether the garbage truck is in the running state.
[0047] In this embodiment, the main air source 204 is the air compressor on the garbage truck, the auxiliary air source 205 is the air storage structure, and the purging structure 201 can be directly supplied with air by the air compressor and air storage structure on the garbage truck. There is no need to set up an additional air source or add other power units. The air storage structure can still supply air when the garbage truck is turned off. This makes the overall cleaning component less complex and simpler, and also greatly reduces the difficulty of manufacturing and installation.
[0048] Specifically, the gas is supplied by an air compressor. After intake, compression, and pumping, the air compressor delivers the final high-temperature gas through a spiral steel pipe to the condenser. As the gas passes through the condenser, the spiral structure inside throws water, oil, and other contaminants onto the inner wall of the valve body, where they flow towards the outlet, simultaneously lowering the temperature of the compressed air. The gas exiting the condenser reaches the dryer, where it is filtered and dried. The remaining gas passes through a four-circuit protection valve and is then divided into three streams, each entering one of three sets of air reservoirs. These three sets of air reservoirs are used for the service brake, parking brake, and auxiliary air supply, respectively. The main air source 204 and the auxiliary air source 205 utilize the air from the auxiliary air reservoir. The air compressor continuously supplies air while the garbage truck is operating, and the auxiliary air reservoir continues to supply air even when the garbage truck is off.
[0049] Among them, the purge switch 203 is a pulse valve, and the air supply delivery structure is also equipped with a pressure reducing valve. The air source in the auxiliary air storage tank is adjusted to the required pressure through the pressure reducing valve, and then pulse control is performed through the pulse valve to realize the opening and closing switching of the air circuit.
[0050] Furthermore, the lifting of the loader 4 is achieved by controlling the hydraulic cylinder solenoid valve via the "loader lift" function on the garbage truck's control panel. Simultaneously, the air pulse valve is controlled, energizing the electromagnet and opening the switch hole, thus unblocking the air passage and cleaning the guide trough 101. After the loader 4 reaches its position, the control pulse valve is de-energized, closing the switch hole and cutting off the air passage. Automatic cleaning effectively reduces the workload for operators. Additionally, the loader 4 typically only opens during unloading at the garbage transfer station, simultaneously cleaning the guide trough 101 at this time. This not only avoids clogging of the sewage tank but also improves cleaning efficiency and prevents secondary pollution during cleaning.
[0051] It is understood that, as an alternative implementation, the pneumatic pulse valve can also be controlled by a separate control unit on the control panel.
[0052] In this embodiment, the storage structure includes a sewage tank 301 and a connector 302. The sewage tank 301 has an internal cavity, and the connector 302 has an internal connecting channel. The sewage tank 301 is connected to the sewage guiding structure through the connector 302. The structure is simple and reliable and easy to process and manufacture.
[0053] In this embodiment, there are multiple connectors 302, which are spaced apart along the extension direction of the sewage guiding structure. All connectors 302 can introduce sewage into the sewage tank 301, effectively improving the reliability and efficiency of sewage collection in the sewage tank 301.
[0054] Specifically, there are no restrictions on the specific structure of the connector 302; it can be tubular or trough-shaped, as long as it can transport sewage.
[0055] In this embodiment, the sewage tank 301 is provided with an openable drain door 303 on its side wall, and a drain switch 304 is provided on its side wall. The drain switch 304 can be connected to an external pipeline to discharge sewage, or it can be opened directly to discharge sewage. When the sewage tank 301 needs to be cleaned due to the small amount of sewage, the drain door 303 can be opened to use tools for cleaning.
[0056] Specifically, the drain door 303 is a swingable door installed on the side walls of both sides of the sewage tank 301, and the drain switch 304 is a tubular valve installed on one side wall of the sewage tank 301. The size of the drain door 303 is larger than that of the drain switch 304.
[0057] Furthermore, since the inside of the sewage tank 301 also needs to be cleaned regularly, the larger drain door 303 makes it easier for operators to clean. In order to reduce the impact of the gas inside the sewage tank 301 on the operators, the drain switch 304 or the drain door 303 can be opened when cleaning the inside of the sewage tank 301. At this time, the purging structure 201 is opened, and the gas blown out by the purging structure 201 can enter the sewage tank 301 through the connector 302 and blow out the gas inside.
[0058] According to an embodiment of the present invention, in another aspect, a garbage truck is provided, which includes: a truck body, a filler 4 and the aforementioned anti-drip device, wherein the filler 4 is connected to the truck body and the anti-drip device is disposed on the filler 4.
