Description
Technical field
The utility model relates to feed mixing machine, specifically relates to a kind of hermetically-sealed construction of feed mixing machine agitating device.
Background technology
The basic structure of the agitating device of existing a kind of feed mixing machine is: a mixing drum bottom is connected with ring flange, and the outer end of ring flange is connected with bearing block, and the screw conveyor shaft that is loaded on the bearing block stretches in the mixing drum.The bearing block of existing this agitating device is directly to connect with the outer end of ring flange, the screw conveyor shaft of this agitating device and the hermetically-sealed construction between ring flange are to be with seal disc on screw conveyor shaft is positioned at the position of ring flange inboard, are cooperated with the inner face of ring flange by seal disc and realize sealing.The deficiency that existing this hermetically-sealed construction exists is: even seal disc has sealing effectiveness, enter into bearing block but still have dust, because bearing block directly connects with the outer end of ring flange, the dust that enters in the bearing block will retain within it, and then can aggravate the wearing and tearing of bearing block inner bearing and axle journal.
The utility model content
The purpose of this utility model is to provide a kind of feed mixing machine agitating device hermetically-sealed construction, and the sealing structure can guarantee should not have in the bearing block dust to enter.
For achieving the above object, the utility model adopts following scheme: feed mixing machine agitating device hermetically-sealed construction, the bottom of mixing drum is connected with ring flange, the outer end of ring flange is connected with bearing block, being loaded on screw conveyor shaft on the bearing block passes ring flange and stretches in the mixing drum, screw conveyor shaft is positioned on the position of ring flange inboard and is with seal disc, the inner face of seal disc and ring flange is sealed and matched, the inner face that bearing block and ring flange are adjacent is provided with sealing gasket, at the cushion block that is supported with between the outer end of sealing gasket and ring flange more than two, has the space between sealing gasket and ring flange outer face, screw conveyor shaft passes between the position of ring flange and ring flange has the slit, and the space that has between this slit and sealing gasket and ring flange outer face is communicated with.
By such scheme as seen, at first the setting of sealing gasket can guarantee that dust is difficult for entering in the bearing block, even there is dust to pass through seal disc, these dust also can be entered into the space between sealing gasket and ring flange by the slit between screw conveyor shaft and ring flange, under the state that screw conveyor shaft rotates, effect by centrifugal force and air-flow, the dust that enters into this space can be shed air, dust is difficult to stop in this space, the outside of sealing gasket does not then have the accumulation of dust, and then can guarantee should not have in the bearing block dust to enter.
The utility model is rational in infrastructure, reliable, and it has the characteristics of good sealing effect, long service life.

The specific embodiment
Further specify the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1, Fig. 2
The feed mixing machine agitating device that the utility model provides includes mixing drum 2, screw conveyor shaft 1 and sleeve 3, the hermetically-sealed construction of this agitating device is: the bottom of mixing drum 2 is connected with ring flange 6, the outer end of ring flange 6 is connected with bearing block 8, being loaded on screw conveyor shaft 1 on the bearing block 8 passes ring flange 6 and stretches in the mixing drum 2, screw conveyor shaft 1 is positioned on the position of ring flange 6 inboards and is with seal disc 4, seal disc 4 is sealed and matched with the inner face of ring flange 6, bearing block 8 and ring flange 6 adjacent inner faces are provided with sealing gasket 14, the bottom of sealing gasket 14 is lined with elastic sealing gasket 13, between the outer end of sealing gasket 14 and ring flange 6, be supported with the cushion block 7 more than two, has space 11 between sealing gasket 14 and ring flange 6 outer faces, screw conveyor shaft 1 passes between the position of ring flange 6 and ring flange has slit 5, and the space 11 that has between this slit 5 and sealing gasket 14 and ring flange 6 outer faces is communicated with.
Screw conveyor shaft 1 axle journal stretches out the axle sleeve 12 that tool shoulder block 12a is housed on the position of ring flange 6, and shoulder block 12a is in the space 11 that has between sealing gasket 14 and ring flange 6 outer faces.The setting of axle sleeve 12, a side can stop dust by shoulder block 12a, second can quicken dust is outwards shed by the shoulder block 12a that rotates.
Referring to Fig. 3
