Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial enlarged view of region A in Fig. 1.
Specific embodiment
The technical solution that the invention will now be described in detail with reference to the accompanying drawings：
Such as Fig. 1, a kind of mixer truck rotary sealing system, the rotary sealing for mixer truck.The mixer truck use notification number for
The patent of CN107344401A《The concrete mixing and transporting car of hollow shaft rotary sealing》The new-type hollow shaft revolution proposed is close
Seal structure：Mixer truck includes installation on the car body and relative to the agitator 1 that car body turns round and can install on the car body simultaneously
The bracket 10 that can be moved with respect to the car body is equipped with rotary sealing lid 3 by floating bearing 8 on the bracket 10, and described time
Turn 3 outer edge of sealing cover to be in contact with the agitator 1 outlet outer edge, contact position is equipped with sealing element, on the one hand realizes close
Envelope turns round rotary sealing lid 3 with agitator 1 relative to 10 fixed part of bracket under the driving of agitator 1, institute
It states and offers through-hole in the middle part of rotary sealing lid 3, feed hopper 7 is equipped with by removably on the bracket 10, for stirring
It mixes and conveys material in bucket 1.
The present embodiment is implemented on the basis of the said structure, it is therefore intended that improves rotary sealing performance.Specific structure is：
The mixer truck rotary sealing system includes being mounted on the overflow cylinder 12 to connect on rotary sealing lid 3 with the through-hole and peace
Discharge barrel 9 mounted in 7 exit of feed hopper；The overflow cylinder 12 for being sleeved on 9 outside of discharge barrel passes through the centre bore of floating bearing 8,
And rear end is located at turn around the rear side of bearing 8, the back edge of the overflow cylinder 12 has the annular radially to extend outward
Flange, for exporting material；There is gap between 12 inner wall of overflow cylinder and 9 outer wall of discharge barrel.
The agitator 1 is protruded into 9 end of discharge barrel, for the material in feed hopper 7 to be delivered in agitator 1.
Due to using telescoping structure, agitator 1 can retain center barrel 2, can also remove it and lengthen going out for feed hopper 7
Barrel 9 restricts the diameter no longer acceptor center barrel 2 at charging, improves charging rate.
Further, the overflow cylinder 12 equally also passes through the bracket 10, and there are gaps between the bracket 10.
When agitator 1 turns round, the rotary sealing lid 3 and overflow cylinder 12 are rotated together with agitator 1, and the then phase of bracket 10
For car body fixed static.Material in agitator 1 is spilt at the gap between 9 outer wall of 12 inner wall of overflow cylinder and discharge barrel
Afterwards, the outside to vehicle can be dredged by overflow cylinder 12, so as to avoid material close to floating bearing 8.Simultaneously as eliminating phase
To the axial seal at revolution, thus also solve the problems, such as that rotary sealing lid 3 is not closed completely.
Such as Fig. 1 and 2, the also splash board 11 of annular, 11 outer edge of splash board is connected with the bracket 10, the splash board
11 are located at the rear side of the overflow cylinder 12, constitute labyrinth seal structure with the annular flange of overflow cylinder 12, stop soil sundries
Gap across overflow cylinder 12 and bracket 10 touches floating bearing 8.
Further, 11 bottom of splash board is equipped with opening, prevents 11 internal water accumulation of splash board.
Such as Fig. 1, further includes the driving device for driving the bracket 10 relative to mixer truck car body anterior-posterior translation, pass through
Translation mode realizes opening and closing of the rotary sealing lid 3 relative to agitator 1, to realize center barrel 2 in the way of translating intussusception
Nestable with discharge barrel 9 docks, it is ensured that charging is smooth not to outflow.Preferably, the driving device includes being set on car body
The oil cylinder 5 that support base 6 and one end are connected with support base 6, the other end is connected with the bracket 10.Using the branch of integral type
Strut configuration combines the hinged fixing end of oil cylinder 5 and support base 6 together, from and while reduce space hold, also mitigate
Weight.
It is additionally provided with the bracket for 5 cylinder body of support oil cylinder on the support base 6, is also possible to：It is set on the support base 6
The sliding block matched with 5 extension end of oil cylinder or pulley support are set, alternatively, installation and the support on 5 extension end of oil cylinder
The sliding block or pulley support that seat 6 matches, purpose are all to undertake the weight of rotary sealing lid 3, mitigate 5 load-bearing of oil cylinder, subtract
Vibration when light charging and the impact to oil cylinder 5, reduce the abrasion of oil cylinder 5, improve the service life and whole system of oil cylinder 5
Reliability and operation stability.
When having center barrel 2 on agitator 1, the front end of the discharge barrel 9 can be straight tube form, be also possible to bore
Cartridge form.Straight tube is easy disengaging, but center barrel 2 and discharge barrel 9 are easy to happen interference；Cone cylinder is likely to encounter convenient for promoting
Stone blocks.It is preferred that using cone cylinder form, while the rubber matched with the center barrel 2 is connected in the front end of discharge barrel 9
Cylinder 4 is in close contact it with center barrel 2, stone is avoided to be detained.
Embodiment two
Such as Fig. 2, the present embodiment and embodiment one the difference is that：Between 12 inner wall of overflow cylinder and 9 outer wall of discharge barrel
Gap at be equipped with central seal ring 13, the central seal ring 13 be inflatable or liquid-filled, for preventing in agitator 1
Concrete overflows.It being overflowed even if existing at this, a small amount of concrete of spilling also will reach vehicle outside along the flange of overflow cylinder 12,
It will not influence the normal work of mixer truck.
