[0001] The present invention relates to the field of sanitation vehicle equipment, and particularly to a sanitation vehicle body and a sanitation vehicle. Background Art

[0002] In the compartments of traditional sanitation vehicles, there are both dry suction air ducts and wet suction air ducts. However, since most of the main structures of the dry suction air duct and the wet suction air duct are shared, it is easy for the liquid and water vapor generated during the wet suction process to backflow into the dry suction air duct and the filter chamber, and in severe cases, it will damage the filtering performance of the filter cartridge and reduce the dust suction performance of the whole vehicle. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a sanitation vehicle body and a sanitation vehicle, which effectively overcome the defects of the prior art.

[0004] The technical solution of the present invention for solving the above technical problems is as follows.

[0005] A sanitation vehicle body includes a body main body. Inside the body main body, there are successively arranged, from the head to the tail, an independent functional chamber, a filter chamber, and a dust suction chamber. The inside of the filter chamber is separated into an upper chamber and a lower chamber by a partition. A plurality of filter cartridge mounting holes penetrating through the partition are evenly distributed on the partition. Filter cartridges connected to the filter cartridge mounting holes are installed in the lower chamber. A first air inlet and a second air inlet are respectively provided through the side wall of the filter chamber connected to the dust suction chamber. Sealing doors that can be opened or closed are respectively provided at the first air inlet and the second air inlet. A gas circulation cavity is provided inside the filter chamber. Inside the gas circulation cavity, there are a dry suction chamber and a wet suction chamber respectively corresponding to and communicating with the first air inlet and the second air inlet. The dry suction chamber communicates with the lower chamber, the wet suction chamber communicates with the air inlet of a blower arranged in the functional chamber, an exhaust port is provided at the top of the functional chamber, and the upper chamber communicates with the air inlet of the blower.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0024] The principles and features of the present invention will be described below with reference to the attached drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0025] Embodiment 1.

[0026] As shown in Figure 1 、 2 、3, and 4, the sanitation vehicle compartment of this embodiment includes a compartment body 1. Inside the compartment body 1, a function chamber 11, a filter chamber 12, and a dust collection chamber 13 that are independent of each other are sequentially arranged from the head to the tail. Inside the filter chamber 12, it is divided into an upper chamber 121 and a lower chamber 122 by a partition (designated by c in the figure). A plurality of filter cartridge mounting holes penetrating through it are evenly distributed on the partition. A filter cartridge 2 connected to the filter cartridge mounting holes is installed in the lower chamber 122. On the side wall where the filter chamber 12 is connected to the dust collection chamber 13, a first air inlet and a second air inlet are penetrated. Sealing doors that can be opened or closed are respectively provided at the first air inlet and the second air inlet. A gas circulation cavity 4 is provided in the filter chamber 12. Inside the gas circulation cavity 4, there are a dry suction chamber and a wet suction chamber that are respectively in one-to-one correspondence and communication with the first air inlet and the second air inlet. The dry suction chamber is communicated with the lower chamber 122, and the wet suction chamber is communicated with the air inlet of a fan 5 arranged in the function chamber 11. An exhaust port is provided at the top of the function chamber 11, and the upper chamber 121 is communicated with the air inlet of the fan 5.

[0027] The usage process is as follows.

[0028] 1) During operation on sunny days, it is a dry suction operation. Open the sealing door at the first air inlet (the second air inlet is closed). During the operation process, dust and impurities first enter the dust collection chamber 13. Under the exhaust action of the fan 5, the air flow direction inside the compartment body 1 is: dust and debris → dust collection chamber 13 → first air inlet → dry suction chamber → lower chamber 122 → filter cartridge 2 → fan 5 → outside. During this process, the gas intercepts dust and debris through the filter cartridge 2, and the filtered gas is then discharged to the outside.

[0029] 2) During operation in rainy weather, open the sealing door at the second air inlet (the first air inlet is closed), open the first gas inlet. During the operation, dust and impurities first enter the dust suction chamber 13. Due to the humid operation environment, almost no dust is generated. Therefore, under the exhaust action of the fan 5, the air flow direction inside the box body main body 1 is: gas → dust suction chamber 13 → second air inlet → wet suction chamber → fan 5 → the outside. During this process, the gas is directly discharged to the outside through the pipeline connected to the air inlet of the fan 5.

[0030] In the overall structural design, the "dry suction air duct" and the wet suction air duct are completely independent, without sharing or cross - using, and there is no situation of air leakage, water leakage, or backflow. It can well protect the filter cartridge 2 during wet suction operation and maintain a good environment in the dry suction channel.

[0031] It should be noted that: there is a dust suction main pipe penetrating the bottom wall inside the above - mentioned dust suction chamber 13, and this dust suction main pipe is used to connect with the suction cup at the bottom of the sanitation vehicle.

[0032] As a preferred implementation manner, the air inlet of the above - mentioned fan 5 is connected with an air duct, and this air duct extends from the above - mentioned lower chamber 122 to be connected and communicated with the bottom or the lower part of the side end of the above - mentioned dry suction chamber.

[0033] In the above - mentioned implementation scheme, there are two interfaces at the air inlet of the fan 5. One interface is communicated with the upper chamber 121, and the other interface is connected and communicated with the wet suction chamber through an air duct (designated as a in the figure). The whole air duct passes through the lower chamber 122. The overall structural layout is compact, the volume remains unchanged, and it does not affect the cleaning effect of the whole vehicle.

[0034] As a preferred implementation manner, an air flow port is opened in the upper part of the side wall where the above - mentioned functional chamber 11 is connected to the above - mentioned filtration chamber 12, and this air flow port is communicated with the air inlet of the above - mentioned fan 5.

[0035] In the above - mentioned implementation scheme, during production, the functional chamber 11 and the filtration chamber 12 are separated by a partition board (designated as d in the figure), and an air flow port is opened on this partition board. The air inlet of the fan 5 can be directly and hermetically docked with this air flow port. The overall structural design is simple, which is convenient for disassembly, installation, inspection, and maintenance.

[0036] It should be supplemented and explained that: at the top of the box body main body 1 corresponding to the filtration chamber 12, there is a detachable maintenance cover plate. At the same time, a maintenance opening for this cover plate is also left on the partition, which is conducive to the operators entering the filtration chamber 12 to overhaul and maintain the internal parts.

[0037] As a preferred implementation manner, the lower part of the side wall where the above - mentioned filtration chamber 12 is connected to the above - mentioned dust suction chamber 13 is recessed towards the inside of the above - mentioned dust suction chamber 13 to form an ash collection area 123. One side wall of the above - mentioned box body main body 1 is provided with an ash discharge port communicated with one end of the above - mentioned ash collection area 123, and a cover plate is provided at the above - mentioned ash discharge port.

[0038] In the above embodiments, a sunken dust collection area 123 is provided at the lower part of the side wall where the filtering chamber 12 is connected to the dust suction chamber 13. After the operation is completed, the entire box body 1 will be tilted and lifted, and the dust on its bottom wall can slide along the bottom wall of the filtering chamber 12 to the dust collection area 123. Then, by opening the dust discharge port at one end of the dust collection area 123, the dust accumulated inside the filtering chamber 12 can be cleaned. The structural design is relatively compact.

[0039] As a preferred embodiment, a screw conveyor 6 spanning the box body 1 is provided in the above dust collection area 123, and the discharge end of the screw conveyor 6 extends to the dust discharge port.

[0040] In the above embodiments, since there is dust raising during the cleaning of the dust and impurities in the filtering chamber 12, therefore, a screw conveyor 6 spanning the box body 1 is designed in the dust collection area 123. The screw conveyor 6 can be started when discharging the dust cleaned in the filtering chamber 12. After opening the cover plate of the dust discharge port, the dust is discharged evenly and at a slow speed. Its discharging method is active discharging, and it is slow and uniform, with less dust raising, more environmentally friendly. Moreover, the automatic dust discharging operation is more convenient to use, reducing the labor input.

[0041] As a preferred embodiment, the bottom wall of the above filtering chamber 12 is inclined downward from its head end to its tail end.

[0042] In the above embodiments, the bottom wall of the filtering chamber 12 is designed to be inclined, and the dust accumulated on it can slide along its surface to the dust collection area 123, which is more conducive to the aggregation of dust to the dust collection area 123, and the dust discharging is more convenient and thorough.

[0043] As a preferred embodiment, two sets of telescopic components 7 corresponding to the dry dust suction chamber and the wet dust suction chamber are installed in the upper chamber 121. The telescopic ends of the two sets of telescopic components 7 respectively penetrate the corresponding dry dust suction chamber and wet dust suction chamber and are connected to the corresponding sealing doors. The telescopic components 7 are used to drive the sealing doors to move horizontally in the dust suction chamber 13, so as to open or close the corresponding first air inlet or second air inlet.

[0044] In the above embodiments, the sealing doors at the first air inlet and the second air inlet adopt a horizontal moving structural form. Specifically, when it is necessary to open the sealing door, the telescopic end of the corresponding telescopic component 7 extends, and the sealing door is pushed away from the corresponding first air inlet or second air inlet (the sealing door moves horizontally in the dust suction chamber 13). When it is necessary to close the sealing door, the telescopic end of the telescopic component 7 retracts, and the sealing door can be driven to move to fit and cover the corresponding first air inlet or second air inlet.

[0045] Generally, the telescopic component 7 can be installed at the upper end of the partition. Moreover, the gas circulation cavity 4 is installed on the side wall where the filtering chamber 12 is connected to the dust suction chamber 13, and its lower end penetrates the partition.

[0046] In this embodiment, the telescopic assembly 7 is a hydraulic cylinder or a pneumatic cylinder, and its piston rod penetrates through the side wall of the corresponding dry suction chamber or wet suction chamber.

[0047] It should be added that: actually, the gas circulation cavity 4 as a whole can be a bin structure with one end open, and its open end is hermetically and fixedly attached to the side wall where the filter chamber 12 is connected to the dust suction chamber 13.

[0048] In this embodiment, a dry suction chamber and a wet suction chamber (not shown in the figure) are arranged at intervals in the direction across both sides of the box body 1 within the gas circulation cavity 4, and each chamber is provided with a sealing door and a telescopic assembly 7.

[0049] Embodiment 2.

[0050] As Figures 1 to 4 shown, the sanitation vehicle of this embodiment includes the sanitation vehicle box body in Embodiment 1. The above-mentioned sanitation vehicle box body is installed at the upper end of the chassis of the above-mentioned sanitation vehicle. A suction cup assembly 8 is provided below the chassis of the above-mentioned sanitation vehicle. The above-mentioned suction cup assembly 8 has a suction port. The dust suction chamber 13 is provided with a dust suction pipe penetrating its bottom wall. The suction port of the above-mentioned suction cup assembly 8 is connected and communicated with the lower end of the above-mentioned dust suction pipe through a pipeline.

[0051] In this embodiment, after the suction cup assembly 8 sucks in the road dust and debris, it enters the dust suction chamber 13, and then the dust and debris stay in the dust suction chamber 13 (the dust and debris are dumped by opening the tail gate at the tail end of the box body 1), and then the dry suction mode and the wet suction mode can be switched according to the on-site operation environment (by switching the opening and closing states of the two sealing doors).

[0052] As a preferred implementation manner, as Figure 5 shown, the above-mentioned suction cup assembly 8 includes a suction cup housing 81 with an open lower end. The upper part of the above-mentioned suction cup housing 81 is provided with the above-mentioned suction port. A rotary brush 82 spanning it is rotatably installed in the above-mentioned suction cup housing 81. A high-pressure water pipe 83 spanning it is provided in the above-mentioned suction cup housing 81. A plurality of nozzles 84 are arranged along the length direction of the above-mentioned high-pressure water pipe 83. The above-mentioned high-pressure water pipe 83 is connected to the high-pressure water circuit of the above-mentioned sanitation vehicle.

[0053] In the above-mentioned implementation scheme, a motor connected to the rotary brush 82 is arranged at one end of the suction cup housing 81. During operation, the lower end of the suction cup housing 81 is close to the ground, and the rotary brush 82 rotates, so that the road sweeping and suction operation can be realized. At the same time, the water tank of the sanitation vehicle can be operated to supply water to the high-pressure water pipe 83, so as to wash the ground obliquely downward through a plurality of nozzles 84, realizing a cleaning mode that synchronizes the three functions of sweeping, washing, and suction.

[0054] Of course, different cleaning modes can be turned on according to different cleaning environments, as follows.

[0055] 1) For floating garbage cleaning, pure suction (the rotary brush 82 does not rotate) or rotary suction (the rotary brush 82 rotates) can be adopted.

[0056] 2) For cleaning in muddy, muddy slurry, and compacted working conditions, the rotary suction + flushing method (that is, supplying water to the high-pressure water pipe 83) is adopted. The rotary sweeper first loosens and sucks away the garbage, and finally uses high-pressure water to flush and turn up the deep residues and suck them away, so as to realize multi-purpose operation of one vehicle and full-condition operation.

[0057] As a preferred implementation manner, a sweeping disc assembly 9 is further provided under the chassis of the above-mentioned sanitation vehicle. There are two sweeping disc assemblies 9, which are respectively distributed at both ends of the suction cup assembly 8.

[0058] In the above implementation scheme, the sweeping disc assemblies 9 are distributed at both ends of the suction cup assembly 8, and the garbage bins on both sides of the road surface can be swept to the front side of the suction cup assembly 8, so as to clean the road surface efficiently and thoroughly.

[0059] Sprinklers for side flushing can also be added at both ends of the suction cup assembly 8, which are connected to the high-pressure water of the sanitation vehicle itself to flush both sides of the road surface.

[0060] It should be added that the installation of the suction cup assembly 8 and the sweeping disc assembly 9 under the chassis of the sanitation vehicle belongs to the conventional design in the art, and the conventional installation method is also used in this application, so it will not be elaborated here.
