AI Technical Summary
Technical Problem
Due to the limited operating space inside tunnels, small tunnel boring machines are difficult to install automated slag removal devices, resulting in low automation of slag removal and affecting tunneling efficiency.
Method used
Design a slag removal device for a tunneling machine, including a shovel arm that can move back and forth and tilt, and a pusher blade. The slag removal is automated through the movement of the shovel arm and the pusher blade. The movement range is small, there is no need to transport it upwards, and it occupies little space.
Benefits of technology
It achieves a high degree of automation in slag removal operations, with small movement range, reducing space occupation and improving the slag removal efficiency of the tunneling machine.

Abstract
The application provides a tunneling machine slag removal device, a slag removal system and a tunneling machine. The slag removal device comprises a rack, a shovel arm connected to the rack and capable of moving forward and backward and performing a pitching motion, a push shovel hingedly connected to the front end of the shovel arm, a first pitching oil cylinder capable of driving the push shovel to pitch backward to unload slag, and a hinge point above the hinged position of the shovel arm, and the other end of the first pitching oil cylinder being hingedly connected to the shovel arm. The slag removal system comprises a belt conveyor and the above-described slag removal device. The tunneling machine comprises a rear matching trailer system, the rear matching trailer system comprising two or more trailers, and the above-described slag removal system being connected to the front end of at least the first trailer. The tunneling machine slag removal device and the slag removal system can realize automatic tunnel slag removal operation through the forward and backward movement and the pitching motion of the shovel arm and the push shovel, and have a small occupied space and are convenient to arrange in a small tunneling machine. The tunneling machine can realize high automaticity small tunnel slag removal operation through the above-described slag removal system.
