Abstract
The invention belongs to the multi-disc type rotary sealing system of engineering machinery field, more particularly to a kind of concrete mixing and transporting car, including material mouth assembly and tank body, it is characterised in that：Material mouth fixed plate, transition disc and pivoting support are sequentially installed between material mouth assembly and tank body, the pivoting support inner ring and transition disc are connected by bolt with tank body, material mouth fixed plate is connected by bolt with material mouth assembly, and pivoting support outer ring passes through clamp card and fixation with material mouth assembly.The present invention reduces the height of vehicle on the premise of ensureing freight volume and security by multi-disc type rotary sealing technology, mainly solving the technical problems that the tank mouth material leakage problem caused by tank body inclination angle is too small.
Description
Technical field
The invention belongs to the multi-disc type rotary sealing system of engineering machinery, more particularly to a kind of concrete mixing and transporting car.
Background technology
Concrete mixing and transporting car of the prior art is prevents concrete material leakage from tank body, often using increase tank body
The mode at angle of inclination overcomes this problem, but increasing Tank tilting angle can cause overall dimensions of a car higher, be not suitable under mine
Operation.If Tank tilting angle diminishes, and the material leakage problem of tank mouth can so occur when in use, Jar opening sealer can be also caused
Part abrasion thereby using reducing significantly.Can only be by the way of amount of concrete be reduced in order to solve this problem in real process
Avoid material leakage.
The content of the invention
In order to solve the above technical problems, the present invention provide it is a kind of not because inclination angle is crossed and the concrete mixing and transporting car of material leakage
Multi-disc type rotary sealing system, technical solution of the present invention are：
A kind of multi-disc type rotary sealing system of concrete mixing and transporting car, including material mouth assembly and tank body, in material mouth assembly and
Material mouth fixed plate, transition disc and pivoting support are sequentially installed between tank body, the pivoting support inner ring and transition disc pass through spiral shell
Bolt is connected with tank body, and material mouth fixed plate is connected by bolt with material mouth assembly, and pivoting support outer ring passes through clamp with material mouth assembly
It is fixed.
Further, the multi-disc type rotary sealing system of concrete mixing and transporting car of the present invention, the material mouth are consolidated
Fixed board offers annular groove, and sealing ring is provided with annular groove.
Further, the multi-disc type rotary sealing system of concrete mixing and transporting car of the present invention, in addition to it is spacing
Plate, one end of the limiting plate are arranged on pivoting support outer peripheral surface, and the other end is arranged in material mouth fixed plate.
The beneficial effects of the invention are as follows：By the assembling of transition disc and pivoting support inner ring, the revolution of tank body both can guarantee that
Motion, while more preferable plugging action is played, concrete is not overflowed between hopper and tank body, tank body can kept former
Inclination angle is diminished on the basis of capacity, reduce vehicle height, be adapted to underground work；Material mouth fixed plate is installed on hopper simultaneously,
And sealing ring is set in material mouth fixed plate annular groove, make to have accomplished sufficient lubrication between each part by adding lubricating oil,
Have and form lubricating oil film between the parts of relative motion, both ensure that the reliability of sealing, improved the use of parts again
Life-span；Meanwhile limiting plate serves the effect of limitation concentricity to each parts, the accuracy and performance of whole system are improved.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention.
Fig. 2 is rotary sealing assembling schematic diagram.
Drawing explanation：
1 material mouth assembly, 2 clamps, 3 tank bodies, 4 limiting plates, 5 pivoting supports, 6 transition discs, 7 bolts, 8 sealing rings, 9 material
Mouth fixed plate.
Embodiment：
For a better understanding and implementation, providing specific embodiment below in conjunction with the accompanying drawings describes the present invention in detail.Illustrated embodiment
It is served only for explaining the present invention, is not intended to limit the scope of the present invention.
Referring to Fig. 1, Fig. 2, the inner ring of pivoting support 5 and transition disc 6 are connected by bolt with the oral area flange of tank body 3；Sealing ring 8
It is assembled in the annular groove of material mouth fixed plate 9；Material mouth assembly 1 and material mouth fixed plate 9 are bolted；Material mouth assembly 1 and revolution branch
Hold 5 outer rings to block by clamp 2, the both ends of clamp 5 are fixed with the outer ring of pivoting support 5 and material mouth assembly 1 respectively by bolt；It is spacing
One end of plate 4 is arranged on the outer peripheral surface of pivoting support 5, and the other end is arranged in material mouth fixed plate 9, limits the concentric of polydisc part
Degree；The outer ring of revolving support 5 is connected with vehicle frame；Between the Internal and external cycle of pivoting support 5 and ensure that lubricating oil fills in the annular groove of material mouth fixed plate 9
Foot, sealing ring 8 are assembled to material mouth fixed plate 9, and coating lubricating oil makes to be formed between two pieces between transition disc 6 and material mouth fixed plate 9
Seal oil film.
