The operating efficiency of access hole.
Preferably, extension spring is provided between the maintenance door and fuselage, the extension spring makes maintenance door seal maintenance with past
The trend of the direction motion of mouth.
By using above-mentioned technical proposal, extension spring pulls maintenance door toward the direction for sealing access hole, is not having maintenance door
There are operating personnel to be maintained at the position for sealing access hole when promoting maintenance door, reduce in feeder maintenance door quilt in the course of the work
The situation that material drives and separated with access hole.
Preferably, the quantity of the extension spring is 2, and is distributed in the both sides of maintenance door.
By using above-mentioned technical proposal, 2 extension springs make it that extension spring is bigger to the active force of maintenance door so that maintenance door is more
The position for sealing access hole is firmly held in, and extension spring is distributed in the both sides of maintenance door so that what maintenance door was born comes
From the pulling force of extension spring evenly.
Preferably, clasp is rotatably connected in the maintenance door, barb is provided with the fuselage, the maintenance door with
When access hole separates, the clasp is fastened with barb.
By using above-mentioned technical proposal, when needing to overhaul middle hanging axis bearing, sliding maintenance door makes maintenance door
Separated with access hole, but in the presence of extension spring, maintenance door is had toward the trend for sealing access hole slip, at this moment make clasp with
Barb snapping, with the position of fixed now maintenance door, to continue the inspection operation of middle hanging axis bearing.
Preferably, the maintenance door is fixedly connected with door lock when sealing access hole between maintenance door and fuselage.
By using above-mentioned technical proposal, feeder in long-term running, because in fuselage material for a long time with
Maintenance door produces friction, and maintenance door has a situation that access hole is taken away by material, and after setting door lock, the position of maintenance door will be by can
It is fixed on by ground on fuselage, reduces the situation that maintenance door is brought away from access hole.
In summary, the utility model has the advantages that：When feeder is run, the sealing gasket in maintenance door supports
Firmly fuselage, and seal access hole, spills to prevent material from access hole, causes the wasting of resources, and the sealing gasket in maintenance door with
The profile fitting of access hole, reduces the space between maintenance door and access hole, so as to reduce between maintenance door and access hole
Can be with the space of material stock so that operationally the material stock between access hole and maintenance door is reduced feeder, reduces resource
Waste, and in the presence of extension spring and door lock, maintenance door is fixed in the position for sealing access hole；And in needs pair
When middle hanging axis bearing is overhauled, maintenance door is slided using handle, maintenance door is separated with access hole, and clasp and barb are buckled
Connect and coordinate with the position of fixed now maintenance door, you can overhauled by access hole centering hanging axis bearing.
