Biaxial rotary cutting type continuous excavation device for frozen soil
The invention discloses a biaxial rotary cutting type continuous excavation device for frozen soil. The biaxial rotary cutting type continuous excavation device comprises a soil collecting device, a rotary soil cutting device, a spiral soil discharging device, a soil throwing device and a direction adjusting device, the soil collecting device comprises a cylindrical soil collecting frame, an opening is formed in the bottom of the soil collecting frame, and an annular fixing plate with a center opening is arranged at the top of the soil collecting frame; a soil throwing device is rotationally connected to a central opening of the fixed plate; the rotary earth cutting device comprises a rotary frame which is arranged on the outer side of the earth collecting frame in a sleeving mode and is coaxial with the earth collecting frame. The bottom of the rotating frame and the bottom of the soil collecting frame are connected through a slewing bearing to form a rotatable structure; a side face cutter set is arranged on the side wall of the rotating frame, and a bottom face cutter set is arranged on the bottom face of the rotating frame. According to the device, the rotary frame is adopted, cutters are evenly distributed at the bottom of the side wall, and an integrated collaborative operation mode of rotary milling, rotary dumping and rotary soil throwing is adopted, so that stable and efficient frozen soil excavation operation in the axial direction and the lateral direction and variable-direction soil throwing operation can be carried out; and the multi-level small-cutting-amount continuous efficient excavation task under the frozen soil condition is achieved.
本发明公开了两轴向旋切式冻土连续开挖装置，包括集土装置、旋转挖土装置、螺旋排土装置、抛土装置及方向调节装置；所述集土装置包括圆柱形集土框，所述集土框底部开口，顶部设置中心开口的圆环形固定板；所述固定板中心开口处转动连接抛土装置；所述旋转挖土装置包括套设在集土框外侧且与集土框同轴的旋转框；所述旋转框底部与集土框底部之间由回转支承连接形成可旋转结构；所述旋转框侧壁设置侧面刀具组，所述旋转框底面设置底面刀具组；所述旋转框中心设置螺旋排土装置，本装置采用旋转框，侧壁底部均布设刀具、旋转铣削、旋转排土与旋转抛土一体化协同作业方式，可进行轴向、侧向稳定高效开挖冻土作业，以及变向抛土作业，实现冻土条件下多层次小切削量连续高效开挖任务。
