The main shaft embolias the lid in, form annular cavity between main shaft and lid, the connecting piece, the shield, the breather pipe is connected to the through-hole on the lid, let in the air current to the annular cavity indoor through the through-hole, the air current passes through the recess on the connecting piece, reach the shield department, behind the shield extrusion air current, the air current is discharged from the gap of junction between shield and the connecting piece, because the existence of air current, the dust can't get into in the main shaft, thereby reach the mesh of dust exhaust, can effectively prevent the card of main shaft from dying, improve the life of main shaft.
Further, the grooves include a first groove and a second groove disposed at one side of the first groove.
Further, the first groove is an annular groove, the second groove is a gear groove, and the second groove is formed in one side, close to the dust cover, of the connecting piece. The air flow passes through the gap between the lug and the inner wall of the cover body and enters the first groove and the second groove.
Furthermore, a convex block is arranged on the outer side of the connecting piece, the convex block is arranged on one side close to the through hole, and the first groove is arranged between the convex block and the second groove.
Furthermore, one end of the dustproof cover is provided with an inserting ring, and the inserting ring is inserted into the connecting piece and is connected with the connecting piece.
Furthermore, the through hole is L-shaped, and the connecting piece is a copper piece. An L-shaped through hole is arranged, so that the outer side and the inner side of the cover body are communicated.
According to the above technical scheme, the utility model provides a pressure boost dust exhaust structure of cutting main shaft, embolia the main shaft in the lid, main shaft and lid, the connecting piece, form annular cavity between the shield, the breather pipe is connected to the through-hole on the lid, through the through-hole to the indoor air current that lets in of annular cavity, the air current passes through the recess on the connecting piece, reach shield department, behind the shield extrusion air current, the air current is discharged from the gap of junction between shield and the connecting piece, because the existence of air current, the dust can't get into in the main shaft, thereby reach the mesh of dust exhaust, can prevent effectively that the card of main shaft from dying, the life of main shaft is improved.
