DETAILED DESCRIPTION

[0025] The utility model will be further described below by using the drawings, but the embodiments in the drawings do not constitute any limitation to the utility model.

[0026] Embodiment one, as Figures 1 to 3As shown in the drawings, a sweeping vehicle dust collection device, comprising a dustbin, a dust extraction hood 1 arranged above the dustbin, a garbage storage chamber is formed in the interior of the dustbin, a dust extraction chamber 2 is formed in the interior of the dust extraction hood 1 and is communicated with the garbage storage chamber, an air outlet 32 is formed in the upper surface of the dust extraction hood 1 and is communicated with the dust extraction chamber 2, a fan 4 is arranged at the air outlet 32, and a filter screen 5 is arranged in the dust extraction chamber 2 below the air outlet 32.

[0027] As shown in the drawings, Figures 1 to 3 the dust extraction hood 1 comprises a main body lower cover 11, a movable upper cover 12 which is arranged on the upper end of the main body lower cover 11 and can be opened and closed, the dust extraction chamber 2 is formed in the interior of the main body lower cover 11, the air outlet 32 is formed in the movable upper cover 12, and the fan 4 is fixedly installed on the movable upper cover 12.

[0028] Further, as shown in the drawings, Figure 2 and Figure 3 the main body lower cover 11 is embedded with a vibration mounting bracket 61 above the filter screen 5 in the dust extraction chamber 2, the rear end of the vibration mounting bracket 61 is hinged to the main body lower cover 11 through a pivot, and the vibration mounting bracket 61 is screw-fastened with a vibration motor 62.

[0029] During the working process of the sweeping vehicle, the movable upper cover 12 is in a closed state, the controller of the sweeping vehicle controls the fan 4 to start, the negative pressure suction force generated by the fan 4 causes the ground garbage to enter the garbage storage chamber of the dustbin, and due to the filtering and blocking effect of the filter screen 5, the garbage entering the garbage storage chamber is retained in the garbage storage chamber, so as to realize the storage of the garbage in the dustbin.

[0030] It should be pointed out that in the process of the negative pressure suction force causing the garbage to enter the garbage storage chamber, when the airflow passes through the dust extraction chamber 2 and is discharged through the air outlet 32, the dust is filtered by the filter screen 5 and retained on the filter screen 5. During use, the worker can start the vibration motor 62 through the controller of the sweeping vehicle, at this time the fan 4 is in a stopped state, the vibration motor 62 generates a vibration effect and transmits the vibration effect to the filter screen 5, at this time the filter screen 5 vibrates and shakes off the dust attached to the filter screen 5, so as to realize the dust cleaning of the filter screen 5 and avoid the accumulation of dust on the filter screen 5, which causes the filtering performance of the filter screen 5 to be weakened, and avoid the cleaning efficiency to be reduced due to the accumulation of dust on the filter screen 5.

[0031] The movable upper cover 12 of the present embodiment one adopts an openable and closable structure design, and the vibration mounting bracket 61 of the present embodiment one is installed on the main body lower cover 11 through a hinged manner; when it is needed to take out the filter screen 5 and perform deep cleaning, the worker opens the movable upper cover 12 and lifts the vibration mounting bracket 61 upward, and then takes out the filter screen 5 from the interior of the main body lower cover 11.

[0032] In summary, the dust collection device of the sweeper in this embodiment has the advantages of novel structural design and convenient dust cleaning of the filter screen 5, and can effectively improve the cleaning efficiency of the sweeper.

[0033] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that the rear end of the movable upper cover 12 is hinged to the rear end of the main body lower cover 11 via a hinge.

[0034] Hydraulic struts 13 are installed between the movable upper cover 12 and the main lower cover 11. The upper and lower ends of the hydraulic struts 13 are hinged to the movable upper cover 12 and the main lower cover 11 on the corresponding sides, respectively.

[0035] It should be explained that the hydraulic strut 13 in this embodiment 2 serves to facilitate the opening of the movable upper cover 12.

[0036] Example 3, as Figures 1 to 3 As shown, the difference between this embodiment 3 and embodiment 2 is that: the front end of the movable upper cover 12 is provided with an upper cover latch 14, and the front end of the main body lower cover 11 is provided with a lower cover latch 15 corresponding to the upper cover latch 14; when the movable upper cover 12 is closed, the upper cover latch 14 and the lower cover latch 15 are engaged.

[0037] Example 4, as Figure 2 and Figure 3 As shown, the difference between this embodiment four and embodiment two is that: the front end of the vibration mounting bracket 61 is equipped with a mounting bracket buckle 71, and the movable upper cover 12 is equipped with a hook 72 corresponding to the mounting bracket buckle 71, and the mounting bracket buckle 71 and the hook 72 are engaged.

[0038] Since the mounting bracket latch 71 and hook 72 are engaged, when the movable cover 12 is opened, the vibrating mounting bracket 61 flips upward synchronously with the movable cover 12 to improve the convenience of removing the filter screen 5.

[0039] Example 5, as Figure 3 As shown, the difference between this embodiment 5 and embodiment 1 is that: the lower surface of the main body cover 11 is provided with an air inlet 31 that communicates with the garbage storage chamber of the garbage bin, and the exhaust chamber 2 is equipped with a lower sealing ring 81 surrounding the air inlet 31, and the lower surface edge of the filter screen 5 is in contact with the lower sealing ring 81.

[0040] As for the lower sealing ring 81 in this embodiment, it can effectively prevent dusty airflow from entering the exhaust chamber 2 through the gap between the filter screen 5 and the lower cover 11 of the main body, thereby improving the filtration effect of the filter screen 5.

[0041] Example 6, as Figure 2 andFigure 3 As shown, the difference between this sixth embodiment and the first embodiment is that: an upper sealing ring 82 is installed at the upper end of the main body lower cover 11; when the movable upper cover 12 is closed, the upper sealing ring 82 is locked between the movable upper cover 12 and the main body lower cover 11.

[0042] For the upper sealing ring 82 in this embodiment, when the movable upper cover 12 is closed, the upper sealing ring 82 can ensure the airtightness of the joint between the movable upper cover 12 and the main body lower cover 11, so as to prevent outside air from entering the exhaust chamber 2 from the joint between the movable upper cover 12 and the main body lower cover 11, thereby ensuring the negative pressure suction when the fan 4 is started.

[0043] Example 7, as Figures 1 to 3 As shown, the difference between this embodiment seven and embodiment one is that the upper surface of the movable cover 12 is screwed with a fan cover 9 that has a hollow shape, and the fan cover 9 is used to protect the fan 4.
