[0002] The domestic construction machinery industry has developed rapidly, especially rotary drilling rigs. Due to their strong applicability, they are widely used in building foundation engineering. Rotary drilling buckets are used frequently. When this machine is drilling in soil, its working surface is often covered with a large amount of muddy soil, which affects the drilling effect.

[0003] Chinese patent discloses a rotary drilling bucket with anti-adhesion function (authorization announcement number CN 212079212 U). The inner wall surface of the drill barrel is designed with irregular protrusions and non-smooth surfaces, which can increase the disturbance of the soil inside the drill barrel and destroy the water film on the surface of muddy soil, thereby reducing the amount of soil adhesion on the inner surface of the drill barrel. However, simply setting internal protrusions is not ideal for anti-adhesion of the drill bucket, and the claw of the drill bucket is a major area of ​​soil adhesion, lacking effective anti-adhesion means. Utility Model Content
