| description | The utility model discloses an orientated dust emission and depositing cover for a high air pressure down-the-hole drill. The orientated dust emission and depositing cover comprises a dust depositing cover, a filter screen and an orientated dust emission plate, wherein the dust depositing cover comprises two completely symmetric portions, left and right portions, an airtight member is arranged on the upper portion of the dust depositing cover, a grid hollow-out portion is arranged on the lower circular portion of the dust depositing cover, the filter screen is arranged in the dust depositing cover, and the orientated dust emission plate movably covers the external surface of the grid hollow-out portion. When the orientated dust emission and depositing cover is in use, the dust depositing cover is opened from a clamping bolt end, and the upper opening is clamped on the drilling rod. The dust depositing cover and the clamping bolt are closed, and the direction of the orientated dust emission plate is adjusted. When boring starts, the orientated dust emission and depositing cover starts to deposit and emit dust. The orientated dust emission and depositing cover effectively controls high air pressure boring dust, is high in wind interference immunity, minimizes dust dispersion, prevents workers from sucking too much dust, and improves construction working environment. The orientated dust emission and depositing cover is simple in integral structure, easy for operation and maintenance and low in cost, and employs environmental friendly materials. The orientated dust emission and depositing cover is suitable for multiple drilling and construction environment, especially for drilling work in windy fields. |
