The buffer surface 7321 can abut the surface of the guide part 733 and guide the elastic part 732 to deform.

[0037] Reference Figure 3 and Figure 4 The fan 72 is fixed to the inner wall of the cabinet 71 facing the guide surface 7331 by bolts, and a storage gap 7311 for dust storage is reserved between the inner wall of the cabinet 71 and the plate surface of the mounting portion 731 away from the guide portion 733; when the material is discharged from the discharge end of the gantry conveyor 6 and falls on the guide surface 7331 due to its own gravity, the guide portion 733 slides toward the direction close to the mounting frame due to the pressure of the material, the buffer surface 7321 abuts against the guide portion 733 and guides the elastic portion 732 to deform, and the material is discharged from the discharge port 712 along the guide surface 7331, and the elastic portion 732 is guided The pressure on the portion 733 disappears, the elastic portion 732 rebounds elastically, and the guide portion 733 slides in the direction away from the mounting portion 731, thereby realizing the back and forth sliding of the guide portion 733, causing the dust on the guide surface 7331 to vibrate. At the same time, when the fan 72 is running, the air is driven to impact the guide surface 7331 and the fallen materials, driving the dust in the materials into the storage gap 7311, thereby collecting the dust, making it difficult for the dust to be discharged into the atmosphere, avoiding the occurrence of dust pollution, and ensuring that the staff is not easily exposed to the dust environment, thereby ensuring the health of the staff.

The dust on the surface of plate 751 is cleaned by impeller 761 which is coaxially fixed to the end of the reciprocating screw 763 facing the outlet air duct 713. When the air in the storage gap 7311 is discharged from the outlet air duct 713 along the surface of the filter plate 751, the air impacts the blades of the cleaning impeller 761, driving the cleaning impeller 761 to rotate, driving the scraper 762 to slide on the surface of the filter plate 751 along the axis of the reciprocating screw 763. There is no need for an external power device to drive the reciprocating screw 763 to rotate, thereby reducing energy loss and embodying the concept of energy saving.

[0045] The implementation principle of an environmentally friendly bulk grain special ship unloader in Example 2 of the present application is as follows: the material discharged from the discharge end of the gantry conveyor 6 falls on the guide surface 7331 due to its own gravity, and the guide part 733 slides in the direction close to the mounting frame due to the pressure of the material. The buffer surface 7321 abuts against the guide part 733 and guides the elastic part 732 to deform, and the material is discharged from the discharge port 712 along the guide surface 7331. The pressure of the elastic part 732 caused by the guide part 733 disappears, and the elastic part 732 elastically rebounds, and the guide part 733 slides in the direction away from the mounting part 731, realizing the back and forth sliding of the guide part 733, driving the dust on the guide surface 7331 to vibrate. At the same time, when the fan 72 is in operation, it drives the air to impact the guide surface 7331 and the fallen material, driving the dust in the material into the storage gap 7311, realizing the collection of dust, making it difficult for the dust to be discharged into the atmosphere, avoiding the occurrence of dust pollution, and ensuring that the staff is not easily exposed to the dust environment, thereby ensuring the health of the staff.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
