On the other hand, pulverized raw material becomes powder as crushed material, falls the bottom of scraper bowl main body 7, and 3 outlet openings 20 are set in the bottom of scraper bowl main body 7, from this outlet opening 20 pulverized crushed material is discharged.Usually, in order to improve crushing effect, it constitutes, and outlet opening 20b, 20c with cover 21 covering sides only discharge from the outlet opening 20a suitable with the position, whereabouts of crushed material, and other outlet opening 20b, 20c is used for maintenance etc.
The wire lath of regulation mesh or the grate 22 of perforate steel plate are set on outlet opening 20a, the crushed material of designated size is passed through.According to pulverizing purpose, select shape, size, the material of mesh, this grate 22 is installed.Therefore, the crushed material that passes through from this outlet opening 20a is generally certain.The thick crushed material that does not pass through is discharged from peristome 8 when scraper bowl reverses up and down.
The mode of present embodiment 1 such as above-mentioned formation, certain mode that not only is defined in present embodiment 1.For example, belt is the explanation of carrying out as V-shape belt, and the toothed belt of odontoid is also passable, and under the little situation of load, flat belt also can.In any case, belt is an elastic body, because the function that absorbs vibration is arranged, so when pulverizing by scraper bowl 3, have the vibration of alleviating, promptly alleviates the effect to the damage of scraper bowl 3 that is accompanied by that impact force produces.In addition, because be the formation that to change the steel plate of the wire lath of outlet opening 20a or perforate, so can change the thing of suitable form according to raw material.
[breaking method of raw material]
Then, carry out pulverizing the explanation of the breaking method of the raw material in the scraper bowl 3 of scraper bowl of lid at the band of the mode of this enforcement.As shown in Figure 2, if swing to the position that scoops up raw material by scraper bowl 3, then pulverize and cover 12 and close.The action that scoops up raw material is covered 12 closing state from pulverizing.Is the wobbling action of fulcrum by making scraper bowl 3 with fulcrum 2, utilizes the leading section of scraper bowl main body 7 to scoop up raw material, and the front portion in the scraper bowl main body 7 of packing into, that is, and among the spatial portion 7b between the outer wall of the pulverizing lid 12 of scraper bowl main body 7 when closing.
If further make scraper bowl 3 swing, then pulverize cover 12 with the wobbling action interlock of scraper bowl 3, open gradually, raw material is packed into covers among the pulverizing chamber 7a that 12 inwall constitutes by scraper bowl main body 7 and pulverizing.At this moment, because armature spindle 9 is in rotation status, so the strike effect of 12 backwash plate lining 16 cover in the strike by hammer 11 and pulverizing, a little pulverizes raw material, with the outlet opening 20a discharge of crushed material from the bottom of scraper bowl main body 7.
In addition, under the state of charging feedstock, cover 12 angles of opening regulation,, can prevent that also pulverized crushed material from dispersing to the outside of scraper bowl 3 by the raw material that is loaded into later even pulverize.As shown in Figure 3, if scraper bowl 3 becomes the state of approximate horizontal, then scoop up release, raw material is loaded into pulverizing chamber 7a side.In addition, disperse to the viewpoint of the outside of scraper bowl 3 from preventing crushed material, preferably even without the state that reaches Fig. 3, be loaded into pulverizing chamber 7a rear flank at raw material, scraper bowl 3 is returned to the state of Fig. 2, closes to pulverize cover 12, proceeds to pulverize and moves.
If the raw material that is scooped up is all pulverized, then scraper bowl main body 7 scoops up raw material, above-mentioned repeatedly action.Because by such operation, in scraper bowl main body 7, little by little pulverize raw material, so can seek the stabilizing of the spinning movement of armature spindle 9.With fill in the scraper bowl main body, the method in the past of Fen Suiing is compared quickly, situation of the present invention is owing to be to pulverize gradually, so avoided being accompanied by the overburden of pulverizing, simultaneously, one side is pulverized because one side prevents to disperse, so, all be good state aspect environment at secure context.
In addition, beyond impacting, the raw material one side is mixed with other raw material along with the rotation of armature spindle 9, and one side is mutual repeated friction in pulverizing chamber 7a, is pulverized.Like this, because one apply impact towards raw material, one side is the action of collision repeatedly repeatedly, so can more effectively pulverize.Because this action is undertaken by 2 rotor drives 10,, can obtain the good pulverizing rotation of balance so that motor need not is very big.So, being pulverized is that the following crushed material of designated size is outside outlet opening 20a is discharged to scraper bowl main body 7.
If for a certain reason, when the raw material of failing to pulverize always remains in the scraper bowl main body 7, also can make 7 counter-rotatings of scraper bowl main body, crushed material is discharged from peristome 8 sides.
