Detailed Description

The following description of the embodiments of the present invention will be made with reference to the accompanying drawings.

As shown in fig. 1-4, the dust ring of the drilling machine of the utility model is characterized in that the dust ring comprises a base plate 1, a fixed dust ring 3 fixed on the reverse side of the base plate 1, a sliding dust ring 2 arranged on the front side of the base plate 1, an air cylinder 4 connected with the sliding dust ring 2 through a push-pull rod 2-4,

the base plate 1 comprises a drill jack 1-1 arranged in the middle, two slide ways 1-2,

the sliding dustproof ring 2 comprises a dustproof ring 2-1 and a sliding plate 2-3 connected with the dustproof ring 2-1 through a fixed sliding rod 2-2, the air cylinder 4 is connected with the sliding plate 2-3 through a push-pull rod 2-4, and the sliding plate 2-3 slides along the two sliding ways 1-2.

The drill inserting hole 1-1 is 1.5-2 times of the diameter of a drill rod of the drill.

The dustproof ring 2-1 is made of rubber or polyurethane, and the fixed dustproof ring 3 is made of rubber or polyurethane.

The utility model discloses a rig dust ring mainly comprises base plate, fixed dust ring, slip dust ring, reservoir.

The base plate is a basic structure plate of the device, and the middle part is a drilling machine jack 1-1 with the diameter of the drilling rod of the drilling machine being 1.5-2 times, so that the drilling rod can be directly inserted conveniently; the two slide ways 1-2 are slightly thicker than the fixed slide bars 2-2 of the sliding dustproof ring 2 in diameter.

The sliding dust ring 2 is divided into three parts, the dust ring 2-1 is made of rubber or polyurethane materials, is formed by hardness and can be flexibly attached to a drill rod without causing abrasion of the drill rod, the sliding plate 2-3 is a thin hard metal plate and mainly plays a role in fixing the dust ring and connecting a push-pull rod, the dust ring 2-1 is connected with the sliding plate 2-3 through the fixed sliding rod 2-2 and penetrates through a slideway 1-2 of the base plate 1 to slide in a push-pull mode, and the push-pull rod 2-4 is a metal rod and plays a role in connecting the sliding dust ring 2 with the air cylinder 4.

The fixed dust ring 3 and the sliding dust ring 2 are made of the same material and are fixed on the reverse side of the substrate 1 through screws.
