Fast and continuous window sidetracking drilling device

The invention belongs to the field of petroleum drilling, and particularly relates to a fast and continuous window sidetracking drilling device. The fast and continuous window sidetracking drilling device comprises a drill rod, a drill bit, a sleeve and a whipstock, and drilling fluid passing cavities are formed in the drill rod and the drill bit respectively; the top of the drill rod is connected with a drilling mixture injecting device, the drilling mixture injecting device comprises a slush pump, the slush pump is connected with the top of the drill rod through a main pipeline, the drill rod is connected with a rotary driving device, and an injecting pipeline with the two ends communicated with the main pipeline is arranged on the main pipeline and provided with a balance pipeline; the balance pipeline is connected with a steel shot injecting tank, a steel shot inlet is formed in the upper portion of the steel shot injecting tank, a steel shot outlet is formed in the bottom of the steel shot injecting tank and connected with the injecting pipeline, a steel shot vibrator is arranged under the steel shot injecting tank, injecting pipeline valves are arranged at the positions, connected with the main pipeline, of the two ends of the injecting pipeline respectively, and a main pipeline valve is arranged on the main pipeline. Steel shot impact and the drill bit can continue to be used for rock breaking together to complete sidetracking operation without replacing the drill bit by pulling the drill bit out or adopting a construction technology, well deviation can be prevented, and the drill bit can be protected.
