Grouting material feeding device of shield machine

Abstract

When a shield machine is carrying out tunneling, the space of the diameter direction of the shield machine is strictly limited, but the space of length direction is larger. Thus, a grouting material feeding device of shield machine can only be designed into a long and narrow structure. The grouting material feeding device of the shield machine in the invention compromises a body frame, a hoist which is connected with the top of the body frame, a bunker which is connected with the hoist, a receiving screw conveyer, a vertical screw conveyer and a discharge port. The grouting material feeding device of shield machine also comprises a grid plate unloader, a bunker locator and a weighing instrument. The grid plate unloader is positioned at the bottom of the bunker and connected with the bunker. The bunker locator is positioned below the bunker. The weighing instrument is positioned below the bunker locator. The receiving screw conveyer is arranged on the weighing instrument. The weighing instrument is arranged on the bottom surface of the body frame. The grouting material feeding device of shield machine solves the technical problems of too much accumulated material in the bunker and a high accumulated material ratio. The grouting material feeding device of shield machine has the advantages of being smooth in discharging material of the bunker, low in accumulated material ratio, less number of times in carrying material on the unit length of tunneling, and reducing the transportation load and cost of tunneling the tunnel.

Description

technical field [0001] The invention relates to a device for moving powder or granular material through a silo for a certain distance, and then discharging and transporting the material to a mixing device after reaching a destination, in particular to a shield machine grouting material feeding device. Background technique [0002] When the shield machine is tunneling underground, the space in the diameter direction is strictly limited, while the space in the length direction is relatively large. Therefore, the feeding device for the grouting material can only be designed as a narrow and long structure. The existing grouting material feeding device of the shield machine adopts the setting form of single feeding port or double feeding port. The disadvantage of this device is that the feeding of the silo is not smooth, and the silo will not accumulate material without external disturbance. More, the ratio of accumulation to material is very high, which increases the number of m...

[0002] When the shield machine is tunneling underground, the space in the diameter direction is strictly limited, while the space in the length direction is relatively large. Therefore, the feeding device for the grouting material can only be designed as a narrow and long structure

The existing grouting material feeding device of the shield machine adopts the setting form of single feeding port or double feeding port. The disadvantage of this device is that the feeding of the silo is not smooth, and the silo will not accumulate material without external disturbance. Too much, the ratio of accumulation to material is very high, which increases the number of materials transported per unit excavation length, and increases the transport load and cost of excavation tunnels
