The fan rotates while driving the driving gear, which drives the linkage shaft to rotate by driving the linkage gear, thereby driving the eccentric wheel to rotate. The eccentric wheel intermittently hits the vibration part to drive the vibration part to slide, thereby driving the filter bag to vibrate, shaking off the dust on the filter bag, reducing the probability of dust adhering to the filter bag and affecting the filtering effect; 6.

The storage box can be disassembled and assembled on the vacuum truck through the articulated platform and the disassembly and assembly mechanism. At the same time, the articulated platform cooperates with the disassembly and assembly mechanism to achieve the effect of auxiliary unloading, and the disassembly and assembly mechanism itself also has a vibration reduction effect.

[0025] The present application discloses a dust-free unloading device for a sweeping type dust collection vehicle, referring to Figure 1 and Figure 2, comprising a rectangular storage box 1 installed on the dust collection vehicle, the storage box 1 is connected with a dust collection pipe 2, the dust collection pipe 2 connects the storage box 1 and the rolling sweeping structure of the dust collection vehicle, and the garbage and dust are transported to the dust collection pipe 2 through the rolling sweeping structure and sucked into the storage box 1 through the dust collection pipe 2, and an exhaust fan 3 is installed on the storage box 1, and the exhaust fan 3 provides suction for the dust collection pipe 2 to absorb dust and garbage. The storage box 1 is provided with a debris discharge port 4, and the debris discharge port 4 is used to discharge the collected garbage. A baffle 5 is hingedly provided on the debris discharge port 4, and the baffle 5 opens or closes the debris discharge port 4 by rotation. A filter screen 6 is provided in the storage box 1, and the filter screen 6 separates the storage box 1. A dust discharge pipe 7 is connected and connected to the storage box 1, and the filter screen 6 separates the dust discharge pipe 7 and the dust collection pipe 2, and the exhaust fan 3 is installed on the dust discharge pipe 7. In this embodiment, the debris discharge port 4 is opened at one end of the storage box 1 in the length direction, and the dust collection pipe 2 is arranged away from the debris discharge port 4. At the top of one end, the dust exhaust duct 7 is arranged at the bottom of the storage box 1, and the filter screen 6 horizontally separates the storage box 1. The space below the storage box 1 is much smaller than the space above the storage box 1. In this embodiment, the lower space is one-fourth of the upper space. The separation of the filter screen 6 will reduce the capacity of the storage box 1. The reduction of the space below the filter screen 6 can reduce the reduction of the capacity of the storage box 1, and also reserve space for dust treatment, thereby reducing the amount of dust that directly blocks the entrance of the entire dust exhaust duct 7. The exhaust fan 3 extracts the gas in the storage box 1 through the dust exhaust duct 7, so that the storage box 1 forms a negative pressure, and the garbage and dust at the mouth of the dust suction duct 2 are sucked into the storage box 1 through the negative pressure. After the garbage and dust enter the storage box 1, they are filtered through the filter screen 6 so that the garbage remains above the filter screen 6, so that the dust falls below the filter screen 6 and is discharged through the dust exhaust duct 7, thereby reducing the probability of dust flying when the subsequent debris discharge port 4 is opened to dump garbage.

[0026] Reference Figure 1 and Figure 2 The filter screen 6 is hingedly arranged in the storage box 1 at one end away from the debris discharge port 4. The filter screen 6 is tilted toward the debris discharge port 4 by rotation. The garbage is guided to the debris discharge port 4 by the tilt of the filter screen 6, thereby facilitating the dumping and discharge of garbage. A linkage rod 8 is arranged between the baffle plate 5 and the filter screen 6. One end of the linkage rod 8 is fixedly connected to the baffle plate 5 and the other end is slidingly hinged to the filter screen 6. The setting of the linkage rod 8 can make the filter screen 6 tilt toward the debris discharge port 4 when the debris discharge port 4 is opened to assist in the dumping of garbage. At the same time, when the debris discharge port 4 is closed, the probability of garbage accumulation at the debris discharge port 4 can be reduced.

The mesh body 63 slides toward or away from the mounting frame 61. When garbage falls onto the mesh body 63, the mesh body 63 accepts the sliding of the compressed elastic member 62, and then resets by the elastic force of the elastic member 62. The elastic member 62 can alleviate the impact force of the falling large garbage, and reduce the probability of the mesh body 63 being damaged. At the same time, the sliding vibration of the mesh body 63 can reduce the probability of garbage blocking the mesh holes on the mesh body 63. When the exhaust fan 3 is exhausting air, the wind force can also drive the mesh body 63 to slide and vibrate, thereby further reducing the probability of the mesh body 63 being blocked.

When the exhaust fan 3 rotates, the driving gear 101 is driven to rotate. The driving gear 101 drives the linkage shaft 103 to rotate by driving the linkage gear 102, thereby driving the eccentric wheel 104 to rotate. The eccentric wheel 104 rotates and intermittently hits the vibrating part 913 to drive the vibrating part 913 to slide, thereby driving the filter bag 92 to vibrate, shaking off the dust on the filter bag 92, and reducing the probability of dust adhering to the filter bag 92 and affecting the filtering effect.
