Abstract

The invention provides a drilling bucket and a rotary drilling rig and relates to the technical field of engineering machinery. The drilling bucket comprises a connecting part and a cylinder, whereinthe connecting part is connected with a drill pipe; the cylinder comprises a first half cylinder and a second half cylinder in butt joint with each other; the first half cylinder is hinged to the connecting part; the second half cylinder is connected with the connecting part; a first connecting rod is connected with the end part of a second connecting rod; at the same time, the other end of the first connecting rod is connected with the inner wall of the first half cylinder; the other end of the second connecting rod is connected with a power head pressure plate; that is, the second connectingrod, the first connecting rod and the first half cylinder form a lever structure; and when the power head pressure plate generates displacement relative to the drill pipe, the second connecting rod is driven to generate movement relative to the cylinder to further drive the first connecting rod to move, and the first half cylinder is pushed to rotate towards the direction far away from the secondhalf cylinder so as to unload soil.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a drilling bucket and a rotary drilling rig. Background technique [0002] In the process of infrastructure construction, drilling construction is usually required. With the advancement of technology and the improvement of automation, rotary drilling rigs are generally used to complete drilling construction. Rotary drilling rig is a comprehensive drilling rig, which can cooperate with many different types of drilling buckets to meet the drilling needs of different formations. Therefore, rotary drilling rigs have been widely used. [0003] During the continuous drilling process of the drilling bucket with the driving drill rod of the rotary drilling rig rotating and pressing down, soil chips are also loaded into the bucket through the valve at the bottom of the drilling bucket. After the bucket is full, move out the borehole, and open the bottom door, and realize t...
