The discharging device comprises a discharging body, wherein diversion trenches which are connected with each other are distributed on the discharging body; and all the diversion trenches which are connected with each other are tilted trenches which are consistent in inclined direction or spiral trenches which are consistent in spiral direction. After the technical scheme is adopted, the discharging device of the shaft end sealing device for the concrete mixer plays a role in preventing slurry in a mixing barrel from intruding into a sealed channel to a certain extent, the slurry in the diversion trenches and the sealed channel of the shaft end sealing device can form a slurry flow along the diversion trenches and thrown back to the mixing barrel, thus the aim of prolonging the service life of the shaft end sealing device is achieved.
Description
Technical field
The present invention relates to the technical field of concrete mixer, be meant a kind of axle end sealing device of concrete mixer especially.
Background technology
At present, the sealing structure of shaft end of the stirring main shaft of concrete mixer, as shown in Figure 1; Comprise shaft end seal part and fuel feeding part; Shaft end seal partly comprises seal channel 11 ' and polyamine fat rubber slab 12 ', and fuel feeding partly has oil supply system and oil supply gallery 21 ', and polyamine fat rubber slab 12 ' is arranged in the seal channel 11 '; And through pressing plate polyamine fat rubber slab 12 ' is pressed on the taper seat that changes hub 13 ', play effect by seal channel 11 '.With the axle head that stirs main shaft serves as in stirring cylinder outer, mixer is; Seal channel 11 ' is that the boundary is divided into inner segment 111 ' and outer section 112 ' with polyamine fat rubber slab 12 '; One end of oil supply gallery 21 ' connects the output of oil supply system, and the other end is communicated to seal channel inner segment 111 '.During work; Through the oil supply system pump grease is delivered to oil supply gallery 21 '; Through oil supply gallery 21 ' grease is delivered to the inner segment 111 ' of seal channel again, through the strain of polyamine fat rubber slab, by seal channel 11 '; Stop the mud in the stirring cylinder to invade agitator shaft end inside, thereby realize the sealing function of axle end sealing device.
The sealing structure of shaft end of the stirring main shaft of this concrete mixer; Assembly precision height and complex process that polyamine fat rubber slab 12 ' requires, difficulty of construction is bigger, because the existence of accumulated error and be difficult to control; Influenced whole assembly precision; Make polyamine fat rubber slab 12 ' and change between the hub 13 ' and can't fit tightly, and can constantly wear and tear the in process of production inner segment of seal channel of the mud in the stirring cylinder, cause polyamine fat rubber slab 12 ' and change between the hub 13 ' intrusion mud easily; Accelerate the 12 ' wearing and tearing of polyamine fat rubber slab, caused polyamine fat rubber slab 12 ' to lose efficacy; And when polyamine fat rubber slab 12 ' lost efficacy, mud just can infiltrate outer section 112 ' of seal channel from the inner segment 111 ' of seal channel and can't get out, and then invaded the axle head to mixer, the damage of the agitator shaft end that causes, the service life of shortening mixer.
Summary of the invention
The purpose of this invention is to provide a kind of discharge mechanism that is used for the axle end sealing device of concrete mixer, it can be beneficial to the seal channel that mud is discharged axle end sealing device, prolongs the service life of axle end sealing device.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is:
The discharge mechanism that is used for the axle end sealing device of concrete mixer has the discharge body, is distributed with the perforation guiding gutter on this discharge body, and each connects skewed slot or the consistent helicla flute of the hand of spiral that guiding gutter is oblique unanimity.
Above-mentioned discharge body comprises outer shroud and the interior ring that is nested, and above-mentioned perforation guiding gutter is for connecting the axial cylinder guiding gutter of above-mentioned outer shroud or interior ring.
Above-mentioned cylinder guiding gutter is opened on the inwall of above-mentioned outer shroud, perhaps is opened on the outer wall of above-mentioned interior ring, perhaps is opened on the inwall of above-mentioned interior ring, perhaps is opened on the inwall and the above-mentioned interior inwall that encircles of above-mentioned outer shroud.
Be distributed with the end face guiding gutter that connects the inside and outside circle of ring in this in above-mentioned on the end face of ring; Each above-mentioned end face guiding gutter is skewed slot or helicla flute, and each above-mentioned end face guiding gutter and each above-mentioned cylinder guiding gutter correspondence one by one are connected and are oblique consistent or the hand of spiral consistent.
An axial end of above-mentioned outer shroud is connected with the ring seat; The interior edge of this ring seat extends in the above-mentioned interior ring; Form to supply above-mentioned in ring respective ends against prominent edge; Be distributed with the end face guiding gutter of the inside and outside circle that connects this prominent edge on one end face of above-mentioned prominent edge ring in above-mentioned, each above-mentioned end face guiding gutter is skewed slot or helicla flute, and each above-mentioned end face guiding gutter and each above-mentioned cylinder guiding gutter correspondence one by one are connected and oblique consistent or hand of spiral unanimity.
After adopting such scheme, discharge mechanism of the present invention, the sealing medium (oil is or/and water) that is flowed to by the seal channel of axle end sealing device in the guiding gutter of discharge mechanism plays the effect that the mud that stops in the stirring cylinder is invaded seal channel to a certain extent.The mud of few part is invaded the guiding gutter of discharge mechanism and the seal channel of axle end sealing device; When discharge mechanism rotated with the mixer main shaft, the mud in the guiding gutter was motionless, according to relative motion principle; The relative discharge mechanism counter motion of mud; Utilize the design feature (with the skewed slot or the helicla flute of the direction of rotation of mixer main shaft) of guiding gutter, then the mud in the seal channel of guiding gutter and axle end sealing device just can form slurry flows along guiding gutter and got rid of back in the stirring cylinder, thereby realizes the purpose in the service life of prolongation axle end sealing device; And the water of leaving in the guiding gutter also can form water-stop, further improves the sealing effectiveness of axle end sealing device.
