Abstract
Description
Technical Field
[0001] This utility model relates to the field of sanitation vehicle technology, and in particular to a double-box garbage bin and a high-speed sweeper. Background Technology
[0002] Accelerated urbanization, increased industrialization, and a surge in transportation volume have led to increasingly severe road pollution, making road sweepers an indispensable piece of sanitation equipment in modern urban management. The suction nozzle and garbage bin, as core components of the sweeper's pneumatic conveying system, have a decisive influence on the sweeper's cleaning performance due to their flow field characteristics.
[0003] Most garbage sweepers on the market currently use a design with a single garbage bin connected to a negative pressure airflow duct. They achieve garbage collection by applying negative pressure to the bin and using a suction nozzle. To improve suction power within the bin, some sweepers have attempted to add negative pressure suction ports to form a dual-suction port structure, increasing suction by increasing airflow inlets. However, the negative pressure airflow generated by the two suction ports creates opposing airflow fields within the bin. If the airflow path is not optimized, this can easily lead to airflow collisions, causing suction power loss and other problems. Utility Model Content
[0004] This utility model aims to at least partially solve one of the technical problems in related technologies. To this end, this utility model proposes a double-bin garbage bin and a high-speed sweeper.
[0005] The technical solution to the technical problem solved by this utility model is as follows:
[0006] This utility model proposes a dual-box trash can, including a trash can body, an openable and closable door at the rear end of the trash can body, and a partition disposed inside the trash can body, dividing the trash can body into a first box area and a second box area; at least two sets of negative pressure airflow pipes are connected to the trash can body and respectively connected to the first box area and the second box area; at least two sets of negative pressure suction pipes are connected to the bottom of the trash can body and respectively connected to the first box area and the second box area.
[0007] Preferably, the two sets of suction pipes penetrate the bottom of the garbage bin body and extend to the upper part of the first bin area and the second bin area respectively, and intercepting hoods are provided at intervals above the suction pipes.
[0008] Preferably, the shroud has a frustum-shaped structure.
[0009] Preferably, the partition includes vertical and horizontal plates disposed within the body of the trash can, and the partition of this shape divides the first bin area into an "L"-shaped structure.
[0010] Preferably, the connection between the vertical plate and the horizontal plate is designed with chamfers or rounded corners.
[0011] Preferably, the bottom of the trash can body has two symmetrical water storage chambers, and a concave clearance opening is provided between the two water storage chambers.
[0012] Preferably, a sewage outlet is provided at the rear of the garbage bin body, and the top of the bin door is connected to the garbage bin body through a hinge structure; a hydraulic telescopic cylinder is hinged on the top of the garbage bin body, and the output end of the hydraulic telescopic cylinder is movably connected to the bin door. The bin door is rotated around the hinge point by hydraulic drive, thereby controlling the opening or closing of the sewage outlet.
[0013] Preferably, at least two sets of filter covers are connected to the inside of the box door. The filter covers are respectively set in the first box area and the second box area. A drain pipe connected to the filter covers is also provided on the box door, and a control valve is provided on the drain pipe.
[0014] This utility model also proposes a high-speed sweeper, including a vehicle body, a car chassis at the rear of the vehicle body, and any of the above-mentioned double-box garbage bins, the double-box garbage bins being disposed above the main beam of the car chassis; a negative pressure fan mechanism, disposed above the main beam of the car chassis and located in front of the double-box garbage bins, having two negative pressure suction ends, the two negative pressure suction ends being respectively connected to two sets of negative pressure airflow pipes; and two sets of suction nozzle mechanisms, disposed below the main beam of the car chassis and respectively connected to two sets of negative pressure suction pipes.
[0015] Preferably, the rear end of the garbage bin body is hinged to the rear end of the main beam of the vehicle chassis; it also includes a front lifting cylinder connected above the main beam of the vehicle chassis, the output end of the front lifting cylinder being hinged to the front end of the garbage bin body.

[0017] 1. In this utility model, a double-box design is adopted to form two independent areas, and each area is connected to a negative pressure airflow pipe and a negative pressure suction pipe.

[0028] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0029] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.
[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0031] like Figure 1 as well as Figure 3 As shown, this embodiment proposes a dual-bin trash can, including a trash can body e, with an openable and closable door 10 at the rear end of the trash can body e. A partition 1 is provided inside the trash can body e, dividing it into two independent first bin area 2 and second bin area 3. It also includes at least two sets of negative pressure airflow pipes 4, which are respectively connected to the trash can body e, preferably above it, and connected to the first bin area 2 and the second bin area 3 respectively. The negative pressure airflow pipes 4 transmit external negative pressure airflow to the two independent areas. A trash filter is provided between the suction end of the negative pressure airflow pipe 4 and the first bin area 2 or the second bin area 3 to prevent the airflow generated by the negative pressure airflow pipe 4 from adsorbing trash inside the trash can body e into the pipe. It also includes at least two sets of negative pressure suction pipes 5, which are connected to the bottom of the bin and connected to the first bin area 2 and the second bin area 3 respectively.
[0032] The core of the dual-box trash can proposed in this utility model lies in dividing the trash can body e into two independent first box area 2 and second box area 3. Negative pressure airflow pipe 4 and negative pressure suction pipe 5 are connected to both areas. The negative pressure airflow pipe 4 applies external negative pressure to the trash can body e, and the negative pressure formed inside the trash can body e is transmitted to the negative pressure suction pipe 5. The negative pressure suction pipe 5 sucks up the external trash and intercepts the trash inside the trash can body e.
[0033] Compared to the traditional single-box negative pressure suction structure, the negative pressure airflow generated by this negative pressure airflow channel may interfere with each other. In this design, two independent areas can prevent gas exchange during the negative pressure suction of garbage, making the airflow distribution more reasonable. The two areas do not interfere with each other, which can effectively avoid the loss of negative pressure suction.
[0034] The advantage of this design is that it can still operate independently and maintain a stable negative pressure when one of the independent housing areas or the components that work with that area are damaged, thus avoiding problems such as overall shutdown.
[0035] In some embodiments, two sets of negative pressure suction pipes 5 penetrate the bottom of the garbage bin body e and extend to the upper half of the first bin area 2 and the second bin area 3, respectively, with intercepting hoods 6 spaced apart above the suction pipes. Preferably, the intercepting hoods 6 have a frustum-shaped structure and are detachably installed on the inner top wall of the garbage bin body e. The design of the intercepting hoods 6 can effectively intercept garbage on the negative pressure suction pipes 5; such as Figure 3 As shown, during operation, the high-speed negative pressure airflow generated by the negative pressure airflow channel carries the garbage into the negative pressure suction pipe 5. The direction of the airflow discharged from the negative pressure suction pipe 5 is changed by the interceptor hood 6, which slows down the airflow speed. At this time, the garbage separates from the airflow under the action of gravity and sinks and accumulates in the corresponding area inside the garbage bin body e. This largely avoids the garbage being sucked into the negative pressure airflow pipe 4 by the negative pressure airflow, or the garbage carried by the high negative pressure airflow being discharged from the negative pressure suction pipe 5 and directly colliding with the garbage bin body e, causing damage to the inside of the garbage collection bin.
[0036] In some embodiments, the partition 1 includes vertical and horizontal plates disposed within the garbage bin body e, and this partition 1 divides the first bin area 2 into an "L" shape, with the second bin area 3 located corresponding to the upper right corner of the garbage bin body e. This layout fully utilizes the internal space of the garbage bin body e, providing reasonable space for the connection of the two sets of negative pressure suction pipes 5, allowing the negative pressure suction pipes 5 to be smoothly connected to the corresponding bin areas, ensuring the effective operation of the negative pressure system. Furthermore, this specific spatial layout allows for the rational planning of the location of the garbage discharge outlet, enabling garbage to be discharged directly and efficiently from the outlet during cleaning, greatly improving the convenience and efficiency of garbage collection.
[0037] Furthermore, chamfers or rounded corners are designed at the joints between the vertical and horizontal panels. This design eliminates the sharp edges and corners at the bottom of the second bin area 3, preventing garbage from accumulating in dead corners, allowing garbage to be discharged from the drain outlet more easily and efficiently, and reducing the difficulty of manually cleaning garbage inside the garbage bin body e.
[0038] In some embodiments, the bottom of the garbage bin body e has two symmetrical water storage chambers 7, each containing several sets of reinforcing ribs 8. A concave clearance opening 9 is provided between the two water storage chambers 7. The two symmetrical water storage chambers 7, in conjunction with the internally fixed sets of reinforcing ribs 8, have water passage holes. This design ensures normal water flow within the water storage chambers 7 while significantly improving the load-bearing capacity and compressive strength of the bottom of the garbage bin body e through structural mechanics design. Water pipes are connected to both sides of the water storage chambers 7, with the other end of each pipe connected to the main water tank on the high-speed sweeper truck, serving as a backup water tank for water storage. Breathing nozzles on both sides of the water storage chambers 7 balance the internal air pressure, ensuring smooth airflow during water filling and emptying.
[0039] refer to Figure 4 In some embodiments, a drain outlet is provided at the rear of the garbage bin body e, and the top of the bin door 10 is connected to the garbage bin body e through a hinge structure. A hydraulic telescopic rod is hinged on the top of the garbage bin body, and the output end of the hydraulic telescopic cylinder 11 is connected to the bin door 10. The bin door 10 is rotated around the hinge point by hydraulic drive, thereby controlling the opening or closing of the drain outlet.
[0040] Furthermore, a base is hinged to the door 10, located in the area where the telescopic cylinder connects to the door 10. A pin is threadedly connected to the bottom of the base, and a limit plate is connected to the vehicle chassis a1. The limit plate has a limit hole for the pin to pass through. When the door 10 is closed by the hydraulic telescopic rod, rotating the pin drives it downward under the helical action until it is inserted into the limit hole, thus achieving further closure of the door 10.
[0041] The hydraulically driven design enables the door 10 to open and close quickly and smoothly, significantly reducing the labor intensity of operators and improving the efficiency of garbage collection compared to the traditional manual opening and closing method. The design of the pin and limit plate allows the pin to be rotated and inserted into the limit hole after the door 10 is closed, achieving a secondary locking of the door 10 and enhancing the seal between the door 10 and the garbage bin body e.
[0042] In some embodiments, at least two sets of filter covers 12 are connected to both sides of the door 10. The filter covers 12 are respectively disposed in the first box area 2 and the second box area 3, preferably in the lower half of the area. The door 10 is also provided with a drain pipe 13 connected to the filter cover 12, and a control valve 14 is provided on the drain pipe 13. The filter cover 12 can effectively intercept garbage and only allow sewage to pass through the drain pipe 13, realizing the initial separation of solid garbage and sewage. Subsequently, the discharge of sewage can be flexibly controlled according to actual needs, reducing the residue of sewage inside the box and avoiding long-term soaking of the bottom and inner wall of the box by sewage, thus reducing the risk of corrosion to a certain extent.
[0043] refer to Figures 2 to 3 This utility model also proposes a high-speed sweeper, which includes a vehicle body a, a car chassis a1 at the rear of the vehicle body a, and any of the above-mentioned double-box garbage bins. The double-box garbage bin is set above the main beam of the car chassis a1. A negative pressure fan mechanism b is also set above the main beam of the car chassis a1. The negative pressure fan mechanism b is located at the front of the garbage bin. The negative pressure fan mechanism b has two negative pressure suction ends, which are respectively connected to the negative pressure airflow pipe 4 to apply negative pressure to the inside of the garbage bin body e. Correspondingly, the negative pressure fan mechanism b has two exhaust ends, which are located at the avoidance opening 9 to discharge the airflow below the avoidance opening 9 to avoid interference between the two. It also includes two sets of suction nozzle mechanisms c, which are located below the main beam of the vehicle chassis a1 and are connected to two sets of negative pressure suction pipes 5 respectively. Under the action of negative pressure, the suction nozzles suck up the garbage below the main beam of the vehicle chassis a1 into the first box area 2 and the second box area 3, and intercept the garbage into the garbage bin body e through the interception hood 6.
[0044] The control valve 14 on the sewage pipe 13 is opened in advance to discharge the sewage in the box after it is separated by the filter cover 12. After the sewage is discharged, the pin locking structure of the box door 10 is manually released. The front lifting cylinder d is started to drive the garbage box body e to rotate and tilt around the tail hinge point. The hydraulic telescopic cylinder 11 is started at the same time to drive the box door 10 to rotate around the top hinge point and open the sewage outlet. As the tilt angle of the box increases, the garbage in the first box area 2 and the second box area 3 is smoothly discharged through the sewage outlet under the action of gravity.
[0045] This process achieves orderly solid-liquid separation and discharge by controlling the sewage discharge, unlocking, lifting, and door opening actions in stages, avoiding the inconvenience of mixed discharge of garbage and sewage. At the same time, mechanical linkage is used to improve discharge efficiency and reduce the intensity of manual cleaning operations.
[0046] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
