[0002] In recent years, slurry shield construction has become a dominant method in tunnel construction for subways, intercity railways, water diversion and supply projects, and power projects. When a slurry shield machine (SBM) excavates complex strata, its quarrying box screens and processes rocks from the slurry. This inevitably leads to the accumulation and blockage of large slag blocks within the quarrying box, necessitating frequent cleaning, which seriously impacts shield construction efficiency. Currently, manual cleaning of the quarrying box is often performed during construction, resulting in low cleaning efficiency, high labor intensity, and significant impact on uncivilized construction practices.

[0008] As a further improvement of the present invention, the upper end of the chute is connected to the lower end of the gate, and the lower end of the chute is provided with a rubber belt, which is overlapped on the transmission belt.

[0009] As a further improvement of the present invention, the transmission belt is connected to a motor, and the transmission belt is driven by the motor to operate.

[0010] As a further improvement of the present invention, a slag bucket car is further included, and the slag bucket car is arranged at the end of the transmission belt.

[0011] The beneficial effects of the utility model are as follows: a gate is provided on the quarrying box. When the quarrying box is blocked, the gate can be opened, and the large pieces of slag in the quarrying box are transported to the transmission belt through the chute and then transported out from the transmission belt, thereby realizing mechanized and automatic cleaning of the large pieces of slag accumulated in the quarrying box, which has the characteristics of high cleaning efficiency, low manual labor intensity, safety and environmental protection.

[0014] Marking description: quarrying box 1, slurry inlet pipe 2, slurry discharge pipe 3, grille 4, gate 5, chute 6, transmission belt 7, dump truck 8. DETAILED DESCRIPTION

[0015] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0016] like Figure 1 、 2 As shown, a cleaning device for a quarrying box 1 of a slurry shield machine includes a quarrying box 1, a slurry inlet pipe 2, a slurry discharge pipe 3, a grille 4, a gate 5, a chute 6, a transmission belt 7 and a hopper car 8.

[0017] The slurry inlet pipe 2 and the slurry discharge pipe 3 are respectively provided with gate valves for controlling the on-off of the pipelines. The slurry inlet pipe 2 and the slurry discharge pipe 3 are respectively connected to the front and rear ends of the quarrying box 1.

[0018] The grid 4 is used to intercept large pieces of slag without affecting the normal operation of the mud-water circulation system. The grid 4 is arranged inside the quarrying box 1 and is a grid-like structure made of round steel. The grid size can intercept large pieces of slag.

[0019] An opening is provided on the side wall of the quarrying box 1 in front of the grille 4, and a gate 5 is provided at the opening. The gate 5 is a hydraulically retractable gate 5 that can be opened and closed. The hydraulic retractable gate 5 is connected to a hydraulic pump station control cabinet, which controls the opening and closing of the hydraulic retractable gate 5. By opening the gate 5, large pieces of slag can fall into the chute 6.

[0020] Chute 6, welded from iron plates, allows large slag to slide down it onto conveyor belt 7. Chute 6 is inclined at a 30° angle, ensuring that large slag within quarry box 1 automatically slides down through it onto conveyor belt 7. The upper end of chute 6 is connected to the lower end of gate 5, and a rubber belt is attached to the lower end of chute 6, which overlaps conveyor belt 7, ensuring that the lower end of chute 6 is positioned above conveyor belt 7.

[0021] The transmission belt 7 is connected to a motor, which drives the transmission belt 7 to operate and is used to transport large pieces of slag.

[0022] A slag trolley 8 is located at the end of the conveyor belt 7 and collects the slag blocks. It consists of a slag trolley and a rail-mounted transporter. The slag trolley is mounted on the rail-mounted transporter. Large slag blocks fall onto the slag trolley after reaching the end of the conveyor belt 7. The rail-mounted transporter is then controlled to move along the track to transport the slag blocks out of the tunnel.

[0023] When the quarrying box 1 is blocked and the mud and water circulation is not smooth, the gate valves of the slurry inlet pipe 2 and the slurry discharge pipe 3 at the front and rear ends of the quarrying box 1 are closed, and the hydraulic telescopic gate 5 is controlled to open through the hydraulic pump station control cabinet. Large pieces of slag slide through the chute 6 to the transmission belt 7. The motor is turned on to drive the transmission belt 7 to rotate. The transmission belt 7 carries the slag blocks to the slag bucket truck 8, and then the slag bucket truck 8 transports them out of the tunnel.

[0024] The above embodiments are only used to illustrate the present invention. Any person with ordinary knowledge in the technical field can make equivalent embodiments by making partial changes or modifications to the technical content disclosed in the present invention without departing from the scope of the technical features of the present invention, and the equivalent embodiments still fall within the scope of the technical features of the present invention without departing from the technical features of the present invention.
