AI Technical Summary
The existing design of the drill rod pre-drill hole in the roller cone drilling rig causes slag and water to splash, leading to increased equipment wear and safety hazards. Traditional protection methods are cumbersome to operate and ineffective.
A mirrored anti-slag and water splashing mechanism is installed on both sides of the drill pipe pre-drill hole on the drill frame platform. The slag-blocking assembly, including a semi-circular outer sleeve and a slag-blocking pad, is driven by a dual electro-hydraulic push rod. The slag-blocking pad is tightly fitted to the drill pipe through hydraulic control to block the splashing of slag and water.
It effectively blocked slag and water, reduced equipment wear, improved the continuity and safety of operations, and lowered equipment maintenance costs.

Abstract
Claims
1. A bit hole anti-sludge water splash device for a rotary drilling rig, comprising a drilling rig platform, a drilling rod reserved hole is arranged on the drilling rig platform, characterized in that: At the lower part of the drill frame platform, a pair of anti-slag and water splashing mechanisms are mirror-mounted on both sides of the reserved hole. The anti-slag and water splashing mechanism includes two identical slag-blocking components and a hydraulic drive component for cooperating and connecting with the slag-blocking components. The hydraulic drive component consists of an electro-hydraulic push rod, a shaft lug A, a shaft pin A, a shaft lug B, a pin B, and a guide seat. The fixed end of the electro-hydraulic push rod is hinged to the shaft lug B through the pin B, and the shaft lug B is fixedly connected to the side wall of the drill frame platform. The guide seat is a guide seat with a mounting hole, and its upper end is fixed to the bottom of the drill frame platform, on the side of the drill rod reserved hole. One end of the shaft lug A is a straight surface, and the other end is an arc surface. The mounting hole of the guide seat is located at the lower part of the reserved hole on the drill frame platform. The telescopic end of the electro-hydraulic push rod is hinged to the straight end of the shaft lug A through the pin A, and the arc end of the shaft lug A is fixedly connected to the slag-blocking component. The slag-blocking assembly consists of a semi-circular outer sleeve and a slag-blocking pad. The arc surface of the semi-circular outer sleeve is fixedly connected to the arc end of the shaft lug seat A. An arc-shaped groove is opened on the inner side of the semi-circular outer sleeve, and bolt holes are opened at equal intervals on the semi-circular outer sleeve. The slag-blocking pad is a semi-circular arc-shaped slag-blocking pad, which is inserted into the arc-shaped groove of the semi-circular outer sleeve and fixedly connected by bolts.
2. The anti-slag and water splashing device for drill rod holes of a roller cone drill rig according to claim 1, characterized in that: The outer diameter of the semi-circular arc-shaped slag-blocking pad matches the arc-shaped groove inside the semi-circular outer sleeve, and the inner diameter of the semi-circular arc-shaped slag-blocking pad matches the diameter of the drill pipe.
3. The bit-to-shaft hole de-sludging water spray apparatus of claim 1, wherein: The semi-circular arc-shaped slag-blocking pad is composed of multiple layers of rubber sheets with wires.
