Shield tunneling machine soil bin ball valve slag clearing device

The invention belongs to the field of shield construction and relates to a shield tunneling machine soil bin ball valve slag clearing device. The shield tunneling machine soil bin ball valve slag clearing device comprises a transferring head connected with a soil bin ball valve, a cylinder is mounted at the right end of the transferring head, a slag clearing rod extends into the ball valve througha pneumatic device or manual operation, and soil in the ball valve is cleared. According to the shield tunneling machine soil bin ball valve slag clearing device, the soil in the soil bin ball valvecan be cleared while the pressure of a soil bin is kept, and it is ensured that in subsequent monitoring operation, a monitoring rod can smoothly extend into the soil bin. 本发明属于盾构施工领域，涉及种盾构机土仓球阀清渣装置，包括与土仓球阀连接的转接头，转接头右端安装有圆筒，通过气动装置或人工操作将清渣杆伸入球阀内，对球阀内的泥土进行清理；本发明能够在保持土仓压力的同时，对土仓球阀内的泥土进行清理，保证后续监测作业时监测杆能够顺利伸入土仓。
