Description

Vertical pitch flour mill

The utility model relates to flour mill, and is concrete relevant with the formula flour mill that dangles.

There is following shortcoming in the traditional formula that dangles flour mill (being Raymond machine): the one, because central shaft is to be bearing on the pedestal of center by the bearing above pedestal bottom, center and the center pedestal, the mating surface of its top bearing is away from bearing-surface, thereby poor rigidity, radial stability is poor, thereby cause the main frame vibration big, not only cause noise big, also increased relevant machine members, shortened the service life of parts; The 2nd, because the hitch point that stick at the plum blossom boom its formula grinding roller set upper side of dangling is fixing nonadjustable, and milling roller surface and bull ring anchor ring since be subjected to physical dimension restriction when mounted with regard to exist a pivot angle be angle or at it both work after a period of time because wearing and tearing form an angle, so its grinding contact-making surface is little; Simultaneously, because milling roller surface and bull ring face is not parallel, conduct the abrasive power that can not be converted into grinding roller to the centrifugal force of grinding roller fully by central shaft, above-mentioned two aspect reasons will cause the not high of such flour mill grainding capacity, and finally influence the production output of its unit interval.

The purpose of this utility model is to provide a kind of main frame good rigidly to the public, and grinding roller and bull ring milling area are stable, and the big vertical pitch flour mill of crush efficiency.

The utility model is made up of base, bull ring, air-intaking box, cover tube, upper and lower bearing block, central shaft bearing, central shaft, drive, relieving tool post, perching knife, plum blossom frame and Burnisher apparatus.Cut in the cover for seat of base and be installed with bull ring, be set with air-intaking box, the cover tube is installed on air-intaking box in the cover for seat outside of base.Step is equipped with at cover for seat center at base, and entad cylindrical bearing of a biserial is equipped with on step endoporus top, and a biserial cylindrical bearing and a plain thrust bearing are equipped with in the endoporus bottom, and suit hypomere in the central shaft in above-mentioned bearing.Central shaft lower end protuberate basic unit also is equipped with drive; Central shaft is positioned at the air-intaking box section and is set with relieving tool post, and perching knife is housed on the relieving tool post; Central shaft is positioned at cover tube section and is set with the plum blossom frame, on the plum blossom frame yoke Burnisher apparatus is housed; The central shaft upper end is sleeved in the interior journal bearing of top chock, and top chock is installed in the cover tube bearing support center of top connection in the cover tube again.Its Burnisher apparatus is made up of grinding roller cover, vertical axis, grinding roller axle, two axle bearings and grinding roller again; Grinding roller is with parallel two sleeves; Vertical axis by the metal (upper suit in the one sleeve, vertical axis two ends up and down is sleeved on the plum blossom frame yoke; The grinding roller axle by the metal (upper suit in its another sleeve, grinding roller axle lower end stretches out sleeve and grinding roller is housed, and the roll surface of grinding roller is over against the bull ring anchor ring.

The utlity model has following advantage: 1, because there is the bearing fixing at cover tube bearing support center the central shaft upper end, so be installed in the plum blossom frame and the Burnisher apparatus good rigidly of central shaft epimere, make whole main frame vibration greatly reduce, this can not only reduce noise, but also can reduce machine members, prolong its service life; 2, because grinding roller cover adopts parallel two sleeve design, make that milling roller surface is parallel contact with the bull ring anchor ring all the time, this not only guaranteed above-mentioned both the abradant surface of maximum is arranged; Simultaneously guaranteed that also the centrifugal force that central shaft conducts to grinding roller is converted into abrasive power (theoretical value is 100%) most effectively, and the improvement of above-mentioned two aspects, promote the raising of this machine production efficiency, and finally improved its production of units output.

Below in conjunction with accompanying drawing and embodiment the utility model is done step explanation:
