Abstract

The utility model discloses a universal pulverizer. The utility model is composed of a housing, a rotating shaft installed on the center of the housing, three cutter blades and moveable cutting blades installed on the housing along an axial direction, wherein, the housing is provided with a feeding hole and a discharge hole, and the three cutter blades are evenly arranged on the rotating shaft along the axial direction; the cutter blades can penetrate through regulating ports through screw bolts to connect with a cutter frame, and the length of the cutter blades can be adjusted. The utility model has the advantages of simple structure and high pulverization efficiency; besides, the service life of each of the cutter blades is long; especially, the utility model is not only suitable for pulverizing dry and brittle materials but also suitable for pulverizing materials of high toughness; besides, the utility model can also be used for milling rice, and diameters of pulverized materials can be conveniently regulated.

Description

General pulverizer

The utility model relates to a kind of general pulverizer.

The patent No. a kind of air draught type multipurpose crusher that has been 93221531 patent disclosure, it is a kind of multifunctional agricultural pulverizer, four equally distributed little axles on circumference are housed on its rotor, two groups of two relative little axles are respectively adorned 4 blades and 6 blades, this machine belongs to hammer type ratary plate formula pulverizer, though compare with similar pulverizer and to have the blade number and reduce, crush efficiency improves, and the blast that blade produces can reduce the big defective of dust, but it still exists following weak point: (1) blade is made complicated, intensity is not high, and service life is short.(2) the hammer type ratary plate comminuting matter time is long.(3) this type is effective to clear-cut character material grinding, but can not pulverize such as good toughness or moistening materials such as rubber, fluoroplastics.(4) this type is the plektron rotating blade owing to what use, can only play pulverization, the husk rice that can not shell, so the scope of application is restricted.

The purpose of this utility model then is to provide a kind of function many, simple in structure, and the life-span is long, pulverizes fast general pulverizer.

The purpose of this utility model is achieved in that it mainly has charging aperture by top, the housing of discharging opening is arranged at the bottom, rotating blade, ledger-plate, rotating shaft constitutes, rotating shaft is installed by enclosure interior central authorities, three rotating blades evenly are installed in the rotating shaft, and rotating blade and ledger-plate are strip, and the long limit of blade is a blade, rotating blade axially is installed in the rotating shaft, and ledger-plate is installed on the inner walls vertically.

Evenly be fixed with the knife rest of band adjustment hole in the rotating shaft axially, adjustment hole is also arranged on the rotating blade knife back, pass adjustment hole by bolt between rotating blade and the knife rest and fix, thereby the length of flexibly changing rotating blade is regulated the gap between rotating blade and the ledger-plate.Similarly also the ledger-plate knife rest can be arranged on the housing, ledger-plate also has adjustment hole, by bolt ledger-plate is installed on the ledger-plate knife rest.

Can offer ventilating opening and connect airduct on the sidewall of housing fixed rotating shaft, the blast that produces when rotating blade rotates like this can be drawn in addition and be used it for anything else.If be further to increase the air blast effect, also airblast blade can be installed near in the rotating shaft of ventilating opening.Also filter screen can be housed on the housing Lower Half bulkhead.

The utility model is compared with conventional art, what it adopted is rotating blade and ledger-plate direct shearing material grinding mode, so good crushing effect, time is short, not only can only more broken clear-cut materials as the hammer type ratary plate grinding mode, for picture rubber, fluoroplastics and so on good toughness, the high or moistening material of intensity is suitable equally, and can slough the wheat bran of paddy, play shelling husk rice effect, the utility model blade structure is simple in addition, firmly, and adjustable gaps between rotating blade and the ledger-plate, therefore long service life is easy to maintenance, can adjust powder particle diameter.When axially rotating blade being installed in addition, it is big to produce blast during the blade rotation, and this blast is not only beneficial to comminuting matter, but also can utilize effects such as making air blast when husk rice.

Below by way of embodiments and drawings the utility model is further described.

Fig. 1 is the present embodiment structural representation.

Fig. 2 is the A-A cut-away view of Fig. 1.

In Fig. 1 and Fig. 2,1 is housing, the 2nd, and charging aperture, the 3rd, rotating blade, the 4th, the blade of rotating blade and ledger-plate, the 5th, rotating blade knife rest, the 6th, the adjustment hole on rotating blade 3 and the knife rest 5, the 7th, rotating shaft, the 8th, motor pulley, the 9th, motor, the 10th, bolt, the 11st, ventilating opening, the 12nd, airblast blade, the 13rd, ledger-plate, the 14th, screen cloth, the 15th, ledger-plate knife rest, the 16th, the adjustment hole on ledger-plate 13 and the ledger-plate knife rest 15, the 17th, ventilation duct, the 18th, discharging opening.

In conjunction with Fig. 1, Fig. 2, there is charging aperture 2 housing 1 top that is combined into by two halves up and down, material falls in the housing 1 thus, and there is rotating shaft 7 in the central authorities in the housing 1, and three symmetrical channels are in axial direction milled on rotating shaft 7 surfaces, the iron plate of burn-oning in groove is made knife rest 5, all having corresponding strip hole on knife rest 5 and the rotating blade 3 is adjustment hole 6, with bolt 10 the two is fixed as integral body, and can be according to as a same reason, two ledger-plates 13 are installed in housing 1, and ledger-plate 13 also is axially to install along rotating shaft 7.Rotating shaft 7 two ends are fixed on the sidewall of housing 1, and an end is connected with motor 9 by belt pulley 8, and the other end stretches out outside the housing 1 and airblast blade 12 is housed, and the housing sidewall that airblast blade is housed has ventilating opening 11, and ventilating opening 11 and airblast blade 12 are covered with ventilation duct 17.On the housing 1 Lower Half bulkhead one deck filter screen 14 is arranged, after material falls into housing 1 by charging aperture, by rotating blade 3 and ledger-plate 13 fast turn-around cutting and grinding powdereds, the granularity thickness is by blade and knife rest length adjustment, the blast effect that produces through rotating blade 3 and airblast blade 12 through the thing grain powder of cutting and grinding after screen cloth 14 from discharging opening 18 dischargings.
