Description
Technical field
This utility model relates to specific gravity screening installation, is specifically related to a kind of stone removing machine for grain eccentric shaft support structure.
Background technology
The gravity separation of corn is the difference according to physical propertys such as proportion, unit weight, coefficient of friction and floating velocities between material, utilizes the automatic classification that they produce in motor process, is undertaken sorting by suitable work surface.Gravity separation is used primarily in the sorting of the corn that granularity is close and proportion etc. facilitate difference bigger.Specific-gravity stoner is widely used gravity separation equipment in corn processing, specific-gravity stoner primary structure includes feed arrangement, de-stone device, drive mechanism and blower fan etc., wherein de-stone device is the core of stone remover, mainly it is made up of sieve nest, air uniform plate, Selected Room etc., de-stone device and blower fan are connected as a single entity, and are driven of reciprocating vibration by eccentric shaft.But at present on the stone remover that some are large-scale, owing to its eccentric shaft is made often long, eccentric shaft is when rotating, and its shearing force being radially subject to is relatively big, poor stability, often easily produces disturbance radially and even bends.
Utility model content
This utility model is intended to provide a kind of stone removing machine for grain eccentric shaft support structure improving eccentric shaft turns stability.
Stone removing machine for grain eccentric shaft support structure in this programme, including the eccentric shaft reciprocally rotated, the supporting seat of ring-type it is fixed with in the periphery of described eccentric shaft, the cylindrical of supporting seat is provided with and the support platform of supporting seat one, described support platform has gathering sill, the bottom land of gathering sill is curved-surface structure, and the curvature of bottom land is identical with the inner circle curvature of supporting seat, the guide post being perpendicular to eccentric shaft laterally it is provided with at supporting seat, the end of guide post is provided with fairlead, and described fairlead is inserted in gathering sill.
The utility model has the advantage of: in eccentric shaft turns process, by coordinating of the gathering sill supported on platform that arranges thereon and guide post, it is rotated there is the effect that guiding is stable, in the end of guide post, fairlead is set, coordinated with gathering sill by fairlead, avoid guide post and directly coordinate the rigidity effect produced with gathering sill, it is easy to the problem damaging guide post.
Further, having the cavity of ring-type inside described supporting seat, be provided with bearing in described cavity, described bearing holder (housing, cover) is connected on the periphery of eccentric shaft.Supporting seat makes the form of cavity, alleviates the weight of supporting seat, simultaneously for stable support eccentric shaft, is provided with bearing in cavity further.
Further, being provided with locking nut on described guide post, described fairlead is threaded on the guide bar, and the end face of fairlead can offset with the end face of locking nut.Fairlead is connected with guide rod thread, when fairlead damages, is convenient for changing, locking nut to fairlead axially carry out spacing, it is prevented that its axial float.
Further, the sidewall at described gathering sill has the pilot hole of arc, and the side of fairlead is provided with pilot pin, and described pilot pin is arranged in described guiding.Further by the cooperation of pilot hole and pilot pin, when eccentric shaft turns, its rotation is carried out stable guiding, and can prevent fairlead from deviating from from gathering sill.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
