Description

Feeding accelerator and friction sheets of jaw crusher

The utility model charging accelerator, friction plate relate to a kind of Cereals Processing Machines device of popularizing with vast rural area.

Disk mill is the Cereals Processing Machines that generally use in the rural area.Owing to taken into account the processing of grain and feed, so charging aperture is big especially.Grain enters from charging aperture and is difficult to be subjected to strong hammering in the pulverizing chamber, because the garden tooth of high speed rotation externally has closure, even grain touches the garden tooth, also is bound on one side, from sliding into the sieve end between the gap of garden tooth and fixed tooth disk.Only some material enters flying in the commentaries on classics district of garden tooth.And very smooth after the use of sieve inwall, half material of pulverizing in case reach synchronously, just slides heating along with flat tooth quickens, and has weakened comminuted.Therefore, the pulverizer resistance is big, the load variations sensitivity, and the heavy Kong Sheng in the end is just sent in charging slightly greatly, and efficient is very low.In order to address this problem, common way is: improve the pulverizer main shaft rotating speed.Writing on the disk mill operation instructions as the production of agricultural machinery factory, Shandong: 5700 rev/mins on 270 types; 5100 rev/mins on 310 types; 4400 rev/mins on 370 types.Improve rotating speed, said positive effect from crushing effect, but the corresponding bearing heating that occurred, vibration is big, phenomenons such as fragile parts.Slide heating in order to reduce material in the sieve bottom, some producer (as Huairen factory) adorns the little axle that the six roots of sensation can be rotated on sieve frame, but effect is also not obvious.

This is suitable for novel purpose is that a kind of new mechanical device is provided on disk mill, and it can make material become accelerating impact by passive hammering, prevents that effectively material from sliding into the sieve end from the garden tooth ends, strengthens comminutedly, reduces resistance, and heating is slided in minimizing.

This is suitable for novel purpose is to find like this: in the active toothed disk center of high speed rotation, by five pages of dress centrifugal impellers; Press one in dress conduit in the center of import material, material enters the centrifugal impeller center by conduit, dishes out with very high linear velocity, produces strong percussion movement.Because charging is by the passive momentum bump that becomes initiatively, so stopped to flow directly to the sieve disadvantage at the end; Simultaneously, loaded onto the friction plate of three/circumference again in the sieve bottom.This friction plate strikes out two kinds of specifications of pointed tooth of zigzag step and step with 0.5 thick iron sheet, to the particle of rotation at a high speed, can play cutting, friction, clash into, and prevent the effect of sliding synchronously.

This is suitable for novel core is charging accelerator, friction plate, feed conduit.The charging accelerator need only punch mantle fiber by having loaded onto just on the original equipment active toothed disk, the feed conduit of inclination is assembled in the middle of big lid of pulverizer and the charging aperture; Can be contained in sieve as for friction plate at the end.Though three's structure simply, is contained on the pulverizer and promptly plays a multiplier role.Because this three kinds of structures have been arranged, momentum bump principle is really brought into play in pulverizer.And the pulverizer of existing use, material enters pulverizing chamber naturally by big charging aperture, and relies on the rotation hammering of garden tooth and quicken, therefore movement velocity and impact that this just is difficult to improve material, have weakened comminuted, reduced efficient, and made a part of materials flow, increased resistance to the sieve end.We know that a people can not break a corn into pieces, and this is because corn is very light, and the low-down cause of the speed that from hand, sends flying.Break object into pieces two factors are arranged: 1, improve movement velocity; 2, strengthen the object quality.Ten thousand tons of wheels hit on reef with the speed of 10 centimetres of per seconds, major break down can take place, and a corn hit on object with same speed, and corn is as excellent as before.The difference of Here it is momentum, momentum=quality * speed (kilogram cel) is so under identical speed, steamer and corn momentum be great disparity too.A corn quality can not become, and can only build up speed, and when speed is increased to certain one-level, hits on object, has just pulverized naturally.The charging accelerator of my development clashes into principle owing to brought into play momentum effectively, so work efficiency significantly improves.The particle that friction plate rotated at a high speed the sieve end produces the resistance drop low velocity, and the cutting rubbing particle makes it be subjected to stronger hammering repeatedly.Because automobile of advancing in the same way with it of the automobile impacting of a benz, it is slow more, injured heavy more to be hit automobile speed; The speed of a motor vehicle is high more, and is injured light more.The two speed of a motor vehicle is identical, also just can not produce the accident of collision.Sieve end particle is subjected to after the resistance, and speed is slow more, and the hammer force that is subjected to is big more.The technical characterictic of Here it is friction plate.

Being suitable for novel concrete structure is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is a disk mill configuration charging accelerator friction plate, the profile of feed conduit.

Describe details and the working condition that is suitable for the concrete device of novel proposition according to this in detail below in conjunction with Fig. 1.

This device comprises pulverizer main body (1), and active toothed disk (2), fixed tooth disk (3) have first road to decide tooth (9) second roads and decide tooth (10) on fixed tooth disk, on active toothed disk, garden, first road tooth (4) second road garden tooth (5) and flat tooth (7) are arranged.In the active toothed disk center, by adorning centrifugal impeller (6).Totally five pages of centrifugal impellers form with 1.5 thick sheet iron riveting systems, then with five centers that are fastened on active toothed disk of bolt.One side of impeller leaves charging hole (8).On charging aperture (11), feed conduit (12) is installed, an end of conduit inserts in the centrifugal impeller charging hole (8), and the other end is fastened to be fixed on sieve and is sealed on the iron plate (13), joins with matrix iron plate (14).On square-bottomed bamboo basket frame (15), opening (16) at the bottom of the sieve, be close to the friction plate (17) of 1/3rd circumference above.On Figure of description (2), the front elevation and the profile of friction plate (17) arranged.Thick 0.5 millimeter of friction plate is stamped to form on punch press, is covered with the pointed tooth of zigzag small stair or step above.

After starting pulverizer, (12) enter the centrifugal impeller (6) material from hopper along feed conduit, after the impeller acceleration, dish out along tangent line, impinge upon first road and decide on the tooth (9).Impinge upon the material on (9), after clashing into repeatedly, weaken speed, with the wind by slot, garden, second road tooth (5) that is rotated at a high speed bump quickens, and bumps against second road again and decides on the tooth (10).Repeat said procedure and fall into the sieve end at last,, fly to change along compass screen surface by flat tooth (7) bump.On the sieve end (16), the friction plate (17) that 1/3rd circumference are housed is on compass screen surface.This friction plate has the pointed tooth of several rows of zigzag small stair or step, as ten million little awl, above the particle that flies to change is hammered onto, until flying out from sieve aperture.

Behind disk mill configuration feeding accelerator and the friction plate, its topmost characteristics are: the pulverizing route of having stipulated material. This route is: hopper, and------------flat tooth hammering---friction plate cutting---blows out sieve aperture to garden tooth bump to centrifugal impeller to feed conduit. Material is dished out along tangent line after entering the centrifugal impeller acceleration. (5100 rev/mins of centrifugal impeller linear velocity 46 meter per seconds of 310 types), material itself have just become that contain can movable body, no matter bump against and have played pulverization everywhere. Add the bump of the flat tooth of knuckle-tooth, the efficient raising does not contain and explains. The common pincers worker of feeding accelerator and friction plate can both get out, adopts if produce the producer of pulverizer, and for raising the efficiency, just need mould, punch press etc. is combined into accessory on the production line, the person of ordinary skill in the field can understand and realize fully.
