Embodiment
Fig. 1 is the front view of facing cutter protective cover provided in an embodiment of the present invention, and Fig. 2 is milling provided in an embodiment of the present invention
The left view of cutterhead protective cover, Fig. 3 is Fig. 2 explosive view.As shown in Figure 1 to Figure 3, the facing cutter protection that the present embodiment is provided
Cover includes：Back cover 1 and front shroud, front shroud include front shroud upper cover plate 21, front shroud lower cover 22 and access panel 23.Wherein, front shroud
Upper cover plate 21 and front shroud lower cover 22 are spirally connected with back cover 1, and front shroud upper cover plate 21 and front shroud lower cover 22 are spirally connected.Access panel
23 side is pivotally connected with front shroud upper cover plate 21, opposite side and the pin joint of back cover 1.
Front shroud uses split-type structural, is made up of front shroud upper cover plate 21, front shroud lower cover 22 and access panel 23, such as schemes
Shape shown in 1, wherein, the curved edge of front shroud upper cover plate 21 is connected by bolt with back cover 1, the arc of front shroud lower cover 22
Edge is connected also by bolt with back cover 1, the edge docked in front shroud upper cover plate 21 with front shroud lower cover 22, will by bolt
Front shroud upper cover plate 21 and front shroud lower cover 22 are connected.
Access panel 23 uses shape as shown in Figure 1, and one side is pivotally connected with front shroud upper cover plate 21 so that manhole
Cover plate 23 can be rotated relative to front shroud upper cover plate 21, and access panel 23 is raised 180 ° by realization, can specifically use hinge 24
Realize pivot joint.The arc-shaped edges of access panel 23 are connected by pin with back cover 1, can refer to Fig. 4, Fig. 4 be in Fig. 1 A-A to section view
Figure.Access panel 23 and back cover 1 can be specifically attached using spring catch 3, in maintenance process, extract spring catch 3, i.e.,
Access panel 23 can be raised, to be overhauled to facing cutter.
When being installed to above-mentioned facing cutter protective cover, back cover 1 is fixed on facing cutter first, then by front shroud upper cover plate
21 are fixed on back cover 1, are then fixedly connected with front shroud lower cover 22 with back cover 1 and front shroud upper cover plate 21 respectively, afterwards will inspection
Repair blind patch 23 to be connected with front shroud upper cover plate 21, finally by access panel 23 and the pin joint of back cover 1, complete facing cutter protective cover
