[0032] The slide rail is fixedly connected to the bottom shield 1 located above the slag chute, the gate slides with the slide rail, and the gate slides up and down along the slide rail to realize the opening and closing of the inclined shaft slag chute, the first end of the hydraulic telescopic rod is hinged to the bottom shield 1, and the second end of the hydraulic telescopic rod is hinged to the gate.

[0033] The hydraulic telescopic rod drives the gate to slide up and down along the slide rail to realize the opening and closing control of the inclined shaft slag chute.

[0034] A discharge port is provided on the gate, and a hinge door is installed on the side hinge of the discharge port. A damping rod is also installed between the hinge door and the gate. The damping rod is an elastic telescopic rod, such as a mechanical spring damping rod, a hydraulic damping rod, etc. The damping rod is used to keep the hinge door in a closed state, and when the debris pushes the hinge door, the damping rod elastically contracts and the hinge door opens.

[0035] That is, under normal conditions, the damping rod supports the hinge door and keeps it in a closed state; however, when the amount of debris increases, it will impact the hinge door, and the damping rod will elastically contract under the action of the debris pushing the hinge door, and the hinge door will open, allowing the increased debris to pass through the discharge port, and after decelerating at the discharge port, continue to be discharged along the inclined shaft slag chute.

[0036] By using a hydraulic telescopic rod to drive the gate to slide along the slide rail, the opening size of the inclined shaft slag chute can be controlled, the slag discharge amount can be freely controlled, and the slag chute can be prevented from being blocked. The operation is convenient and conducive to construction.

[0037] A hinge door is also provided, and a damping rod is installed between the hinge door and the gate. The damping rod is used to keep the hinge door in a closed state, and when the slag pushes the hinge door, the damping rod elastically contracts and the hinge door opens. When the slag discharge volume changes suddenly, the slag discharge can be stopped slowly to ensure that the increased slag passes smoothly, and the slag can be slowed down to avoid the "gushing phenomenon".

[0038] Specifically, the slide rail comprises a first slide rail 2 and a second slide rail 3, and the first slide rail 2 and the second slide rail 3 are both vertically arranged.
