The driving device that movable stand 4 and driving movable stand 4 on vehicle frame move with respect to the car body.It is additionally provided with combination revolving support
Device 6, rotary cap 1 are mounted on movable stand 4 by combining slewing supporting device 6, on the one hand follow movable stand 4 mobile, another
Aspect can follow mixing drum to turn round after conjunction is closed.
The movable stand 4, which can be, to be moved forward and backward along rail mechanism relative to mixing drum, and hinged mode can also be passed through
Installation on the car body, is moved relative to mixing drum in hinged way.Driving device can be hydraulic cylinder, be also possible to cylinder.When
Movable stand 4 is the form being moved forward and backward, and driving device uses hydraulic cylinder；When movable stand 4 is the form hingedly rotated, driving device
Generally use cylinder.The translation or rotation of movable stand 4, realize the opening and closing movement of rotary cap 1.
Feed hopper 5 is installed, the discharge end of the feed hopper 5 is connected in the rotary cap 1 on the movable stand 4
The discharge barrel 3 of the mixing drum is protruded into heart hole.
The specific structure of the combination slewing supporting device 6 are as follows: including the revolving drum 6-3 as inner ring, the revolving drum
The external cylindrical surface of 6-3 is equipped with protrusion and is the rotary track 6-2 of annular；
Combining slewing supporting device 6 further includes preposition ring 6-1 and postposition ring 6-5, the rear end face and postposition ring of the preposition ring 6-1
The front end face of 6-5 be connected by bolt with constitute it is described combination slewing supporting device 6 outer ring, clamping rotary track 6-2 and
Revolving drum 6-3 is equipped with the rail for matching with the rotary track 6-2 at the inner headed face of the front end face of the postposition ring 6-5
Road slot.There is gap between the leading flank of the rotary track 6-2 and the preposition ring 6-1 rear end face.
Preferably, the inner wall of the track groove is equipped with the abrasion ring 6-4 for being in contact with the rotary track 6-2,
The abrasion ring 6-4 can be rigid body, be also possible to elastomer, disconnect at lubricating cavity.Further, in the track groove
The cross sectional shape of wall and the cross sectional shape for wearing away ring 6-4 are L shape, and abrasion ring 6-4 is in a position-stable manner or removably
It is mounted on track groove inner wall, it is preferred to use removably is conveniently replaceable.
The top of the postposition ring 6-5 is equipped with the lubricating cavity for holding lubricant, the track groove and the revolution rail
The be in contact position of cooperation road 6-2 is connected with the lubricating cavity.
Lubricating box 6-6 is also placed in the lubricating cavity.The bottom the lubricating box 6-6 can be equipped with bottom plate, bottom plate
It is equipped with oil outlet, the position of oil outlet is corresponding with the top surface of rotary track 6-2 and rear end face part.Lubricating box 6-6's goes out
Bigger or lubricating box 6-6 that port size can be set is also possible to no bottom plate, up and down, makes lubricating oil can
To go swiftly to regions of lubrication, it is not easy to block.
It is additionally provided with box cover 6-7 above the lubricating box 6-6, is additionally provided with and is injected across the box cover 6-7 into lubricating box 6-6
The lubrication management 6-8 of lubricant.Lubricant can be water or lubricating oil, store after entering lubricating box 6-6 from lubrication management 6-8, and
By oil outlet reach rotary track 6-2 on, along rotary track 6-2 flow, be attached to abrasion ring 6-4 and rotary track 6-2 it
Between contact surface at, be lubricated.When the fluid lubricant using water or good fluidity does lubricant, in lubricating box 6-6
It is provided with the cavernous body for lubricant storage.
1 central aperture edge of rotary cap is fixedly connected with the front end of revolving drum 6-3 by welding manner, is formed good
Leakproofness.
The assembly of the preposition ring 6-1 and postposition ring 6-5 of the combination slewing supporting device 6 are mounted on movable stand 4, or
Postposition ring 6-5 described in person is mounted on movable stand 4, and the discharge barrel 3 also extends through the revolving drum 6-3.Meanwhile preposition ring 6-1
At regular intervals, the convenient connection temporarily disconnected between preposition ring 6-1 and postposition ring 6-5 in maintenance is stayed between rotary cap 1,
Replacement abrasion ring 6-4, and be carried forward movement after abrasion ring 6-4 abrasion to preposition ring 6-1 and postposition ring 6-5 and reserve sky
Between.
Sealing ring 2, the periphery of the inner headed face of the sealing ring 2 and the discharge barrel 3 are also equipped in the rotary cap 1
It is in contact, to realize the sealing between revolving drum 6-3 and discharge barrel 3.
When needing to open rotary cap 1, movable stand 4 moves under the drive of the drive, due to the effect of preposition ring 6-1,
Rotary cap 1 can follow movable stand 4 to move backward opening.When needing to be closed, movable stand 4 is moved forward, at the outer circle of rotary cap 1 with
Mixing drum is in contact, which is typically provided with sealing device, and rotary cap 1 will follow mixing drum to turn round.At this point, combination revolution branch
Opposite revolution occurs between the inner ring and outer ring of support arrangement 6, since movable stand 4 gives back to always by combining slewing supporting device 6
Hub cap 1 applies forward thrust, it is ensured that the sealing of mixing drum, therefore the L shape worn away between ring 6-4 and rotary track 6-2 contacts
Face is primary friction face.With the rotation of rotating ring, lubricant is constantly flowed at the rubbing surface, makes to combine the guarantor of slewing supporting device 6
Hold good working order.Due to being sealedly and fixedly connected between the front end revolving drum 6-3 and rotary cap 1, even if loading
Flowable materials overflowed between revolving drum 6-3 and discharge barrel 3, will not enter combination slewing supporting device 6 inside, thus
It solves the problems, such as combination slewing supporting device 6 obstruction, need frequent maintenance and locking.
