The utility model relates to a rotor of a hammer mill, which belongs to the technical field of feeds, grains and oils, chemical machinery. The rotor of the hammer mill comprises a spindle and hammer racks mounted on the spindle of the rotor at certain intervals. A plurality of hammer pin holes are uniformly distributed on the hammer racks, hammer pins are mounted in the hammer pin holes, each hammer is provided with two hammer mounting holes symmetrical to each other, and is suspended on the hammer pin through one of the hammer mounting holes, the different hammers are respectively disposed in intervals of adjacent hammer racks, each hammer rack is provided with standby pin holes corresponding to the hammer pin holes one by one, and the interval between each of the standby pin hole and the corresponding hammer pin hole is equal to the distance between each two hammer mounting holes. Since the rotor of the hammer mill is provided with the standby pin holes, the link of falling the hammers onto the ground and reweighing the same is omitted completely by adding one pin only, the hammers can be turned and changed conveniently and quickly, replacement time is shortened, labor intensity is lowered, and the original balance of the rotor can be kept.

Description

A kind of beater disintegrating machine rotor

Technical field

The present invention relates to a kind of beater disintegrating machine rotor, belong to feed, grain and oil, chemical machinery technical field.

Background technology

At present; Feed, grain and oil, industrial chemicals are carried out grinding and processing mainly adopt beater disintegrating machine; Beater disintegrating machine comprises casing, be arranged in the pulverizing chamber of casing and be arranged in the rotor of pulverizing chamber, and the top of pulverizing chamber is provided with charging aperture, and the bottom is provided with expansion chamber; Between charging aperture and the expansion chamber screen frame is installed, is fixed with the sieve sheet on the screen frame.Rotor is installed on the rotor main shaft; The rotor main shaft two ends are supported on the frame through bearing block; The disc hammer frame plate is installed on the main shaft by certain intervals, is spaced from each other through main shaft distance bushing between the hammer frame plate, and the outward flange of hammer frame plate is evenly distributed with a plurality of hammer leaf pin shaft holes; The hammer leaf bearing pin is installed in the hammer leaf pin shaft hole, and hammer leaf is installed on the hammer leaf bearing pin and passes through hammer leaf spacer axial restraint.

During pulverizer work, armature spindle drives hammer frame plate and drives the hammer leaf high speed rotating that is contained on the hammer leaf bearing pin, hammer leaf centrifugal development simultaneously.Material gets into pulverizing chamber from the charging aperture at pulverizer top, at first gets into accelerating region, at accelerating region; The decrease speed of material is lower; When getting into pulverizing chamber, contact with hammer leaf, the linear velocity of hammer leaf is higher, and is broken because both huge speed differences cause material to overwhelm; Get into district at full speed then, material flies to the sieve sheet under action of centrifugal force, bumps once more with the sieve sheet, becomes granule by bulky grain, and pulverized small particles material passes the sieve aperture of sieve sheet, under the effect of gravity and auxiliary air draft system, discharges from discharging opening.

Be arranged with two hammer leaf installing holes on the hammer leaf respectively, turn around after being convenient at one end wear and tear to use, prolong the service life of hammer leaf.Traditional rotor need be extracted the hammer leaf bearing pin out; Making all hammer leaves break away from rotor lands; Because in a single day hammer leaf is broken each group of back and mixed easily, before the installation of turning around, must organize hammer leaf and weigh, so that the basic dynamic balance performance that guarantees to reinstall the back rotor to each; And hammer leaf is weighed and is wasted time and energy, if maintenance mans lack a sense of responsibility, it is excessive and cause unbalance serious that weight differential is respectively organized between the hammer leaf in appearance easily; In case and dynamic balancing is bad; Not only increase power consumption, and rotor is easy to damage the base bearing at armature spindle two ends especially.

Summary of the invention

The objective of the invention is to, overcome the problem that exists in the prior art, a kind of hammer leaf conveniently beater disintegrating machine rotor that turns around is provided.

For solving above technical problem; A kind of beater disintegrating machine rotor provided by the present invention; Comprise the rotor main shaft that is positioned at rotor center and be installed on the hammer frame plate on the rotor main shaft by certain intervals; Be evenly distributed with a plurality of hammer leaf pin shaft holes on the said hammer frame plate; In the said hammer leaf pin shaft hole hammer leaf bearing pin is installed, is arranged with two hammer leaf installing holes on the hammer leaf and is suspended on the said hammer leaf bearing pin through hammer leaf installing hole wherein, each hammer leaf lays respectively in the interval of adjacent hammer frame plate; Also be provided with on each said hammer frame plate and the subsequent use one to one pin shaft hole of hammer leaf pin shaft hole, the spacing between two hammer leaf installing holes on the spacing between each subsequent use pin shaft hole and the corresponding hammer leaf pin shaft hole and the said hammer leaf equates.

With respect to prior art, the present invention has obtained following beneficial effect: the present invention is provided with subsequent use pin shaft hole, only increases a bearing pin; Just can save hammer leaf fully and land the link of weighing again, when hammer leaf turns around to use, a bearing pin that increases inserted from an end; From the hammer leaf installing hole of hammer leaf strike end, pass successively while inserting, after new bearing pin is in place, pull up former bearing pin; Promptly realized the use of turning around of hammer leaf, whole process convenient is quick, has shortened the time of changing greatly; Alleviated working strength of workers greatly, and can guarantee that rotor keeps original balance.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation, accompanying drawing only provides reference and explanation usefulness, and is non-in order to restriction the utility model.

Fig. 1 is the structural representation of beater disintegrating machine.

Fig. 2 is the front view of the utility model beater disintegrating machine rotor.

Fig. 3 is the left view of Fig. 2.

Fig. 4 is the stereogram of Fig. 2.

Among the figure: 1 charging aperture; 2 casings; 3 rotors; The 3a rotor main shaft; The 3b cylindrical barrel; The 3c hammer frame plate; 3c1 hammer leaf pin shaft hole; The subsequent use pin shaft hole of 3c2; The 3d hammer leaf; 3d1 hammer leaf installing hole; The 3e bearing pin; 4 screen frames; 5 expansion chambers.

The specific embodiment

As shown in Figure 1; Beater disintegrating machine comprises casing 2, be arranged in the pulverizing chamber of casing and be arranged in the rotor 3 of pulverizing chamber, and the top of pulverizing chamber is provided with charging aperture 1, and the bottom is provided with expansion chamber 5; Between charging aperture 1 and the expansion chamber 5 screen frame 4 is installed, is fixed with the sieve sheet on the screen frame 4.
