[0002] In the construction of cities and daily life, the cleanliness of roads and the quality of environmental sanitation are very important, and a road sweeper is one of the sanitation equipment commonly used at present. With the rapid development of China, road sweeping mechanization is developing rapidly. At present, the sweeping of roads in large cities is mainly carried out by special road sweepers supplemented by manual sweeping, the sweeping of roads in small cities is mainly carried out by manual sweeping supplemented by special vehicles, and the sweeping of roads in towns and villages is mainly carried out by manual sweeping. When the sweeper is working, the road garbage is swept to the front range of the suction nozzle by the sweeping disc, and the fan provides suction for the suction nozzle, so that the garbage is sucked into the garbage can. Therefore, the advantages and disadvantages of the pneumatic system of the sweeper directly determine the suction capacity and use efficiency of the sweeper. At present, the sweeper with strong suction capacity is relatively large in size and is more suitable for sweeping roads in large and wide areas, and is difficult to be used in small cities and complex road conditions.
[0003] At present, the fan outlet exhaust resistance of most schemes is large, and even causes additional fan energy loss, and a relatively complex separation and filtration mechanism is often arranged in the garbage can, which leads to excessive air flow pressure loss, increases the fan energy consumption, and reduces the use efficiency of the fan. Therefore, in order to ensure the suction capacity, the size of many sweepers and the power of the fan are large; and in order to adapt to narrow roads, the size of the vehicle is reduced, which leads to insufficient suction capacity of the vehicle and is difficult to meet the cleaning requirements. Therefore, the technical problem to be solved by the present application is how to improve the suction capacity of the vehicle, so that the sweeper can effectively clean garbage in different working environments.

DETAILED DESCRIPTION
[0027] The technical solutions of the present application will be further described below in combination with specific embodiments, but the present application is not limited to these embodiments.
[0028] As shown in Figures 1 to 5 , the present embodiment proposes an air flow circulation system for garbage cleaning, comprising:
[0029] a garbage can 11, the inside of the garbage can 11 is divided into a first chamber 12 and a second chamber 13 by a baffle assembly 10;
[0030] a suction nozzle 14, the suction nozzle 14 is installed below the garbage can 11;
[0031] a fan 15, the fan 15 is installed in the first chamber 12, and the suction inlet of the fan 15 is connected with the dust suction port of the suction nozzle 14 through a dust suction pipeline 16, and the air outlet 17 of the fan 15 is communicated with the second chamber 13;
[0032] a filter bin 18, the filter bin 18 is installed on the top of the second chamber 13, the exhaust port 19 of the filter bin 18 is connected with the suction nozzle 14 through a back flushing pipeline, and the filter bin 18 is used for filtering the garbage in the second chamber 13.
[0033] The technical effect of the present scheme is that the present scheme has a simple structure, a small pressure loss of the air path, a high suction efficiency, and a high utilization rate of the fan 15. The present scheme can enhance the suction strength of the suction nozzle 14. The fan 15 has a crushing function for segmenting the garbage introduced into the suction nozzle 14 and sending the garbage into the second chamber 13 of the garbage can 11. The filter bin 18 filters the garbage and prevents the garbage from flying out with the airflow. The airflow in the second chamber 13 is sent into the suction nozzle 14 through the exhaust port 19 and the back-blowing pipeline, thereby improving the suction of the suction nozzle 14 so that the suction nozzle 14 can fully suck the garbage. The back-blowing pipeline is not shown in the drawings.
[0034] In addition, the present scheme can reduce the pressure loss of the air path in the system, thereby increasing the garbage accumulation density in the second chamber 13 of the garbage can 11, improving the volume utilization rate of the box, and reducing the probability of pipe blockage.
[0035] Further, the bottom of the filter bin 18 is provided with a filter plate 20, and a plurality of filter holes are arranged on the filter plate 20.
[0036] As an embodiment of the present embodiment, the side plate of the filter bin 18 is a double-layer plate 21. The present scheme has the effect of reducing noise for reducing noise pollution.
[0037] As an embodiment of the present embodiment, a three-way pipe 22 is installed on the suction nozzle 14, and the suction nozzle 14 is provided with a back-blowing gas inlet. The first interface 23 and the second interface 24 of the three-way pipe 22 are used to connect with the back-blowing gas inlet, and the third interface 25 of the three-way pipe 22 is connected with the exhaust port 19 of the filter bin 18 through the back-blowing pipeline. Further, the two back-blowing gas inlets are located on both sides of the dust suction port.
[0038] The technical effect of the present scheme is that the back-blowing gas can be blown from both sides of the suction nozzle 14 to improve the suction of the garbage on the edge of the suction nozzle 14. The back-blowing gas can gather and blow up the garbage on the bottom to the middle, so that the garbage is more easily sucked into the dust suction port, effectively reducing the possibility of blockage and making the system run more smoothly.
[0039] As an embodiment of the present embodiment, the baffle assembly 10 includes a first vertical arm 26, a horizontal arm 27, and a second vertical arm 28. The first vertical arm 26 is fixed on the bottom plate of the garbage can 11. One end of the horizontal arm 27 is fixed on the top of the first vertical arm 26, and the other end of the horizontal arm 27 is fixed with the second vertical arm 28. The second vertical arm 28 is located above the horizontal arm 27.
[0040] As an embodiment of the present embodiment, the fan 15 is fixed on the horizontal arm 27. This scheme can effectively support the fan 15, and the baffle assembly 10 of this scheme adopts a Z-shaped structure, which can increase the space of the second chamber 13, thereby increasing the storage capacity of the garbage.
[0041] Further, the exhaust port 19 is arranged at one end of the second vertical arm 28. The air outlet 17 is arranged at the other end of the second vertical arm 28.
[0042] As an embodiment of the present embodiment, the edge of the second vertical arm 28 is fixed with a support steel frame 29. This scheme is used to improve the stability of the installation of the baffle assembly 10.
[0043] The air circulation track of the present scheme is as follows:
[0044] The rotation of the impeller of the fan 15 provides the total power of the air system. The air path starts from the dust suction port of the suction nozzle 14, passes through the dust suction pipeline, enters the fan 15, and then the air flow is discharged into the second chamber 13 inside the garbage can 11. The air flow passes through the filter bin 18 and is blown back to the inside of the suction nozzle 14 through the exhaust port 19, the back blowing pipeline and the three-way pipe 22. Finally, the air flow flows into the dust suction port of the suction nozzle 14 again to form an air circulation.
[0045] The garbage conveying track of the present scheme is as follows:
[0046] Through the rotation of the sweeping device, the left and right sweeping plates rotate relatively to gather the bottom surface garbage to the middle part of the vehicle, in front of the suction nozzle 14. As the vehicle advances, the garbage enters the suction nozzle 14, passes through the suction nozzle 14 into the dust suction pipeline, and then enters the inside of the fan 15, which is broken and divided into smaller volumes by the fan 15, and enters the second chamber 13 inside the garbage can 11. Due to the action of gravity and air flow, the garbage accumulates from the bottom front side of the garbage can 11. Part of the lighter garbage is blocked by the filter bin 18 inside the box, and finally falls to the bottom of the garbage can 11. The finer dust or particles can pass through the filter screen, enter the back blowing pipeline through the exhaust port, and flow into the suction nozzle 14 through the three-way pipe 22, and then be sucked into the fan 15 and the garbage can 11 again. This effectively avoids the leakage of garbage. At the same time, the garbage is broken and divided into smaller volumes by the fan 15, which can increase the packing density of the garbage inside the box, thereby improving the utilization rate of the internal volume of the garbage can 11.
[0047] For those skilled in the art, without departing from the inventive concept of the present utility model, a number of modifications and improvements can be made, which are all within the protection scope of the present utility model.
