Piston is advanced slowly, and stemming spues via big gun mouth and blocks ferrum mouth.After clay gun has been beaten stemming by clay extruded mechanism, vexed big gun is generally needed
30 minutes or so；During this period, big gun mouth has been at the forefront of high temperature, and molten iron washes away or adhesion in addition, and big gun mouth easily burns
Damage, need periodically to its Replacement and Repair, but big gun mouth is changed and repaired it is time-consuming, take a lot of work and arduously.Make to extend big gun mouth
With the life-span, generally in big gun mouth front end breeching mouth cap as guard member, the broad form of big gun mouth cap presses its coupling between big gun mouth
Mode is divided into：Coordinate connection, screw attachment as shown in Figure 5, as shown in Figure 6 pin connection as shown in Figure 4, but coordinate connecting mode
Because its structure is limited, easily drop when coordinating pine, be difficult to dismantle during spot welding or when coordinating tight, functional reliability is poor, after damage not
Beneficial to replacing；Shown in screw attachment or pin connection, screw or pin are covered easily because molten iron splashes and cause the dismounting of big gun mouth cap tired
It is difficult.
Utility model content
The purpose of this utility model is to provide a kind of quick-changing type big gun mouth cap, to overcome the deficiencies in the prior art, this practicality
It is new big gun mouth to be protected and be changed simple and convenient.
To reach above-mentioned purpose, this utility model is adopted the following technical scheme that：
A kind of quick-changing type big gun mouth cap, including big gun mouth cap body and big gun mouth, wherein big gun mouth external circumferential has multiple uniformly at intervals
Arc chuck, arc chuck are provided with annular slot axially inside, and big gun mouth cap body is axially arranged with two-stage ladder hole, big gun mouth cap
Body large aperture through hole end is circumferentially evenly equipped with multiple arcs boss.
Further, wherein arc boss axial width is not more than the annular slot width on big gun mouth.
Further, arc boss arc length is less than arc length between two adjacent arc chuck of big gun mouth.
Further, big gun mouth cap body large aperture through-hole diameter is identical with big gun mouth outer arcuate chuck diameter, big gun mouth cap sheet
Body small-bore through-hole diameter is identical with big gun mouth mud mouth diameter.
Further, the arc chuck axial length on the outside of big gun mouth and big gun mouth cap body arc boss inner face are to shoulder hole
End face distance is identical.
Further, big gun mouth end and big gun mouth cap body ladder end are equipped with chamfering.
Further, wherein big gun mouth external circumferential has 3 arc chuck, big gun mouth cap body large aperture through hole end uniformly at intervals
Portion is circumferentially evenly equipped with 3 arc boss.
Compared with prior art, this utility model has following beneficial technique effect：
A kind of quick-changing type big gun mouth cap of this utility model, by having multiple arcs chuck uniformly at intervals in big gun mouth external circumferential,
Arc chuck is provided with annular slot axially inside, and big gun mouth cap body is axially arranged with two-stage ladder hole, big in big gun mouth cap body
Aperture through hole end is circumferentially evenly equipped with multiple arcs boss, by big gun mouth cap body arc boss between big gun mouth outer arcuate chuck
Insertion, makes arc boss card set in annular slot, during big gun mouth cap this body running, as stemming is along big gun mouth cap sheet
Body axially-movable, therefore which is solely subjected to axial force, is not in rotation and comes off, this apparatus structure is simple, and coupling reliability is good, and
Connection place is difficult to be affected by environmental factorss such as splashing molten iron, more easy care and dismounting and change, and this weight of big gun mouth cap is little, structure
Simply, low cost.

Specific embodiment
Below in conjunction with the accompanying drawings this utility model is described in further detail：
As shown in Figure 1 to Figure 3, a kind of quick-changing type big gun mouth cap, including big gun mouth cap body 1 and big gun mouth 2, wherein on the outside of big gun mouth 2
Circumferentially-spaced to be evenly equipped with multiple arcs chuck, arc chuck is provided with annular slot axially inside, and big gun mouth cap body 1 is axially arranged with
Two-stage ladder hole, 1 large aperture through hole end of big gun mouth cap body are circumferentially evenly equipped with multiple arcs boss, wherein arc boss axial direction
Thickness is not more than the annular slot width on big gun mouth 2, and arc boss arc length is less than arc length between the adjacent arc chuck of 2 liang of big gun mouth,
1 large aperture through-hole diameter of big gun mouth cap body is identical with 2 outer arcuate chuck diameter of big gun mouth, the arc chuck axial direction on the outside of big gun mouth 2
Length is identical to shoulder hole end face distance with big gun mouth cap 1 arc boss inner face of body, 1 rank of 2 end of big gun mouth and big gun mouth cap body
Terraced end is equipped with chamfering, and 1 small-bore through-hole diameter of big gun mouth cap body is identical with 2 mud mouth diameter of big gun mouth, wherein big gun
2 external circumferential of mouth has 3 arc chuck uniformly at intervals, and it is convex that 1 large aperture through hole end of big gun mouth cap body is circumferentially evenly equipped with 3 arcs
