Detailed description of the invention

For making the object of the application, technical scheme and advantage clearly, below in conjunction with drawings and the specific embodiments, the application is described in further detail.

In the following description, quoting of " embodiment ", " embodiment ", " example ", " example " etc. is shown that the embodiment of so description or example can comprise special characteristic, structure, characteristic, character, element or limit, but not each embodiment or example must comprise special characteristic, structure, characteristic, character, element or limit.In addition, reuse phrase " embodiment according to the application " although be likely refer to identical embodiment, and not necessarily refers to identical embodiment.

The structural representation that Self-suction crusher impeller does not install pin and tup 7 is shown with reference to figure 1, Fig. 1.This Self-suction crusher impeller comprises the front shoe 1 and rear fixed plate 3 that are fixed together by some crushing vanes 2, front shoe 1 center is provided with one enters impeller internal air inlet for wind-force, and one group of adjacent crushing vane 2 and the cavity between front shoe 1 and rear fixed plate 3 form air outlet.

Such material is after impeller internal is pulverized, and the wind-force that can be entered by air inlet is driven it to be expelled to Self-suction crusher sieve from air outlet and enters the bag that gathers materials.

Refer again to Fig. 1, the front shoe 1 between at least one group of adjacent crushing vane 2 and rear fixed plate 3 are respectively at least provided with an installing hole 4.Show Self-suction crusher impeller with reference to figure 2, Fig. 2 and install the top view after tup 7.

As shown in Figure 2, a pin is installed with by fixture (fixture 5 can be a nut) 5 being positioned on same axis two installing holes 4; It is that the center of circle rotates with pin that pin is at least provided with an energy, and rotates the tup 7 of impact comminuting matter with vane rotor.

During impeller High Rotation Speed, huge centrifugal force drives movable tup 7 High Rotation Speed installed on pin, makes the movable tup 7 installed on pin between the sieve and crushing vane 2 of Self-suction crusher, form the axis of a relative closure and the radial ringed comprehensive scope of attack after rotating.

Because tup 7 is arranged on pin actively, impeller is when driving tup 7 High Rotation Speed, and tup 7 can slide, when same pin has multiple tup 7 along pin length direction, mutually can collide between tup 7, affect service life and the impact effect of tup 7; In order to evade this phenomenon, so in an embodiment of the present utility model, pin has the spacer 6 that restriction tup 7 slides along pin length direction.

During in order to ensure vane rotary, the particulate matter in circumference of impeller direction is all impacted effectively at synchronization, between adjacent crushing vane 2, all by pin, tup 7 is installed, and the radial dimension of crushing vane 2 is greater than the radius of front shoe (being alternatively the radius that the radial dimension of crushing vane 2 is greater than rear fixed plate 3) 1 herein.

Self-suction crusher in the past has a lot of corn and coarse granule grain to be easy to gap between original device of shifting block type tup 7 to leak through when impacting, and attacks the sieve of Self-suction crusher directly, occurs leaking the problem pulverized, reduces crush efficiency.In order to increase the hammering area of tup 7 in radial direction, so tup 7 is being arranged in T shape, being in particular one and being made up of axial arm and radial arm; Tup 7 arranges in T shape, thus makes tup 7 at the radial and axial comprehensive scope of attack also forming one fixed width, and the crushing vane 2 simultaneously extending rear fixed plate 3 serves assisted comminution and increases air quantity to strengthen the effect of suction capacity.

When tup 7 in T shape rotates to maximum distance apart to crushing vane 2 edge, the outer tangent plane of tup 7 (B face) to the distance of impeller central is greater than the length of crushing vane 2, now, interior tangent plane (C face) to the distance of impeller central of tup 7 equals the length of crushing vane 2.The granule materials running out of crushing vane 2 can be made so effectively to impact.

As shown in figures 1 and 3, all crushing vane 2 adjacent impeller central sides are fixed together, and the radius of turn of tup 7 is less than the distance of pin to all crushing vane 2 intersections.The seamed edge of contiguous for crushing vane 2 front shoe 1 central side is arranged to a hypotenuse.

After arranging like this, from the wind-force that air inlet enters, due to the stop of crushing vane 2 be fixed together, air outlet can be formed with material from adjacent one group of crushing vane 2 and the cavity between front shoe 1 and rear fixed plate 3 outwards to dish out, when arriving crushing vane 2 top, by tangent plane in tup 7 (C face) impact, more effectively tackle impact through the impact surface that the axial arm thickness direction of tup 7 is formed, and the radial scope of attack be connected to form between the radial arm of tup 7 and pin impacts.

After comprehensive like this strike, powder extrudes this closed circulation with air-flow, rushes at the sieve outside the B face of tup 7, is blown in poly-pocket after sieve, completes whole workflow.

In sum, after arranging tup 7 in T shape, tup 7 effectively can be tackled the grains ejected between crushing vane 2, is impacted, thus improves impact efficiency; Reduce the sieve that bulky grain grain directly clashes into Self-suction crusher simultaneously, cause the flimsy possibility of sieve.The crushing vane 2 lengthened serves assisted comminution and increases air quantity to strengthen the effect of suction capacity.
