The guide plate can be inserted into or drawn out from the through groove on any side by the two through grooves, so that the guide plate can be spanned in the buffer bin.

Preferably, a plurality of downward-inclined buffer plates are arranged on the guide plate, and an included angle alpha between each buffer plate and the corresponding guide plate is 15-40 degrees. The buffer plate can further delay the flow velocity of the air flow, so that the particles with large and medium particle sizes are easier to settle.

Preferably, the baffle is a vibrating plate. The vibration board can prevent the particles with large and medium particle diameters from being adsorbed and staying on the guide plate through vibration. The vibration can be realized by a vibration device commonly available on the market, such as a vibration hammer, an ultrasonic vibration generator and the like.

Preferably, the vertical length of the deflector is 1/4-1/2 of the surge bin height.

Preferably, the upper aperture of the surge bin is 100mm smaller than the lower aperture, the height of the surge bin is 4/5 of the lower aperture, and the thickness of the deflector is 8 mm.

Preferably, the lower opening edge of the surge bin is provided with a flange device. The flange device is used for connecting the dust handling device with other parts, for example, when the outer part of the belt is sleeved with a shell, the buffer bin can be connected to the shell through the flange device.
