Cutting all can be configured along direction of rotation with the tooth 18 and the direction of hitting with tooth 19, and to be integral ground equalization arrangement several with supporter on the periphery of rotor 12.In addition, though not shown, all crushing tooths also all are to be fixed by bolts on the supporter 16 with changing, can change when producing abrasion or breakage.Armature spindle 10 can rotate by not shown bearing and freely be supported on bucket main body 7, and rotor 12 is positioned at the below of bucket main body 7, and the rotation outer peripheral edges of being arranged to crushing tooth are more stretched out to the foreign side of bucket main body 7 than the 9b of edge portion of outlet opening 9.Supporter 16 is formed on the interior structure for swinging of recess 12a of rotor 12 as previously mentioned.
Fig. 3 represents the structure of installing to rotor 12 when hitting pulverizing with tooth 19 by hitting.Rotor 12 is to right rotation under the state of figure.The hunting range of the supporter 16 in the recess 12a is the angle [alpha] between A, the B.This angle is that the straight line with the center O of the center of connecting axle 17 and armature spindle 10 is 2 times of the benchmark angle [alpha] 1 of evenly separating.When rotor 12 rotations, hit with the left side (A side) of tooth 19 near recess 12a.Also furthered simultaneously with tooth 19 with the strike of another direction of rotation adjacency.Furthered with tooth 19 owing to hit, the 19a of tooth portion that hits with tooth 19 becomes the state that lifts.The distance of these 19a of tooth portion outer peripheral edges of armature spindle 10 center O becomes b1 (Fig. 3) from b2 (Fig. 4) relatively, and this relation is b1＞b2, and the angle of pulverizing direction changes.
Strike under this state that slowly lifts is to hit under the state that raw material is involved in, and has therefore improved crushing effect.In addition,, gasket part 20 is set, the hunting range of restriction supporter 16 as adjustment component at this recess 12a.This gasket part 20, though not shown, be fixing means such as employing bolt, it can be fixed on the inwall of recess 12a with freely loading and unloading.The thickness that can change this gasket part 20 is selected to be provided with, and is adjusted at the optimum position thereby will hit with tooth 19.
Fig. 4 is the mounting structure of the rotor of expression when pulverizing with tooth 18 by cutting.Rotor 12 is to anticlockwise under the state of figure.As hereinbefore, supporter is swung in the scope of angle [alpha], and when rotor 12 rotations, the right side (B side) of tooth 18 near recess 12a used in cutting.Also furthered simultaneously with tooth 18 with the cutting of another direction of rotation adjacency.Because cutting is furthered with tooth 18, cutting becomes the state that lifts with the 18a of tooth portion of tooth 18.The distance of these 18a of tooth portion outer peripheral edges of armature spindle 10 center O becomes a2 (Fig. 4) from a1 (Fig. 3) relatively, and as hereinbefore, this relation is a2＞a1, pulverizes angle and changes.Incision under the state that slowly lifts, identical with aforementioned strike with tooth 19, be under the state that raw material is involved in, to pulverize, therefore improved crushing effect.
At recess 12a, when supporter 16 swing, must guarantee that crushed material do not sneak into.For this reason, as shown in the figure, the both sides that are arranged on choice direction on supporter 16 can produce the cover 21 of elastic deformation.This cover 21 also will cover the recess of supporter 16 sides of adjacency, forms the structure of one, produces elastic deformation always to contact with rotor-side.This cover 21 is arranged to also will cover the side of supporter 16, and when supporter 16 carried out wobbling action, under any state, crushed material can not invaded in the recess 12a yet.More than the structure of the crushing tooth of Jie Shaoing is the width along rotor 12, and it is staggered to be configured to 3 row as shown in Figure 2 in the present embodiment.
Pulverized raw material, as crushed material powder fall the bucket main body 7 the bottom, the bucket main body 7 the bottom become outlet opening 9, crushed material directly falls.And as previously mentioned, the rotation outer peripheral edges of crushing tooth are stretched out laterally from the 9b of edge portion of outlet opening 9.Therefore, when downward direction was piled up the inadequate raw material of pulverizing, the bucket main body descended downwards, and the bottom of disintegrating bucket 3 can directly push raw material, under this state, when making rotor 12 rotations, can pulverize deposit.This action is especially by cutting tooth 18, Yi Bian it is crowded broken simultaneously to rotate raw material, can further promote to pulverize.This operation is more effective in engineerings such as the betterment of land, by the extruding cumulose soil, makes the rotor rotation by cutting with tooth 18, cumulose soil is mixed to disintegrate pulverize.
The present invention is the disintegrating bucket with various functions, is not the device that baroque parts are set.Crushing tooth changes the position in swing, be to make rotor just change counter-rotating, carry out the simple structure of comminution process, and cost is low, has improved crush efficiency.
More than introduce the concrete mode of implementing, the invention is not restricted to this mode certainly.For example: supporter is illustrated to line up 4 five equilibriums, but is not limited thereto, the size of bucket main body, and corresponding pipeline can be decided to be suitable shape, quantity etc.And characteristics of the present invention are to change the position by swing, as the structure of disintegrating bucket, also can form by the swing crushing tooth and change the structure of position and the structure of the textural association that is fixed.
