Setting a plurality of mounting holes can improve the strength of the connection of the lower connecting plate.

[0009] A further technical solution is that ear plates are installed on the outer surface of the cover body.

[0010] A further technical solution is that reinforcing ribs are installed in the cover body, and the reinforcing ribs are respectively connected to the top and bottom of the cover body. The strength of the side walls of the cover body is improved by providing the reinforcing ribs, so that the cover body is not easily deformed under negative pressure, thereby improving the durability of the cover body.

[0011] The utility model has the following advantages: the utility model can adjust the air intake volume of the air inlet by setting a handle connected to multiple groups of air regulating plates through a chain, so that no other equipment is needed to assist in adjusting the air intake volume. The structure is simple and the convenience of operation is improved. By setting a conical upper wind hood, the wind speed at the upper wind hood can be increased to form a negative pressure, thereby increasing the flow speed of dust in the upper wind hood, so that the hood body has a better dust suction effect. By setting reinforcing ribs to improve the strength of the side wall of the hood body, the hood body is not easily deformed in a negative pressure state, thereby improving the durability of the hood body.
