Abstract

The utility model provides a planetary inscribed circle rolling crasher, which can break block-shaped pure materials, such as limestone, coal gangue, etc. The utility model comprises a driving part, a vertical shaft part, a cylinder part and an upper cover part. When the material is put into the cylinder of the crusher, the material is broken into smaller particles and discharged out of the machine body after impacted and rolled by a plurality of planetary cones of the vertical shaft part. The utility model adopts a rolling and crushing method. The utility model has the advantages of small vibration impact force, low noise, compact structure, small size, large breaking ratio, low power consumption, etc.

Description

Planetary inscribed circle stitching crusher

The utility model relates to a kind of disintegrating apparatus, especially a kind of planetary inscribed circle stitching crusher that can carry out fragmentation to some block brittle materials such as lime stone, gangues.

At present, in the building material machinery industry, particularly in the cement machinery manufacturing industry, various disintegrating machines are arranged as " conical vertical fine crusher ", the patent No. be 89208109.0 and the patent No. be 91220259.0 " vertical impact-pendulum roller suspend mill " etc., but because its smashing principle only limits to impact, strike back, push, roll, thereby its crushing efficiency is very low, energy can not make full use of, unit material metal consumption is big, consumable accessory is changed frequent, vibratory impulse power is big, and noise is big, has a strong impact on environment and infringement workers ' health.

The purpose of this utility model is in order to overcome above-mentioned the deficiencies in the prior art part, to seek a kind of novel smashing principle, replaces modes such as original disintegrating machine impact with the roll extrusion of inscribed circle.As everyone knows, the efficient of roll extrusion is higher, approximately is about 70% of above-mentioned form crumbling method power consumption, so this new disintegrating machine is higher by about 30% than the efficient of traditional disintegrating machine.

The purpose of this utility model is achieved in that a kind of planetary inscribed circle stitching crusher, it includes material bin, motor, belt pulley, main shaft, rolling bearing, cylindrical shell, discharge bucket, loam cake, base, thrust bearing, the cylindrical shell upper end is connected with loam cake, the lower end linked to each other the end of with, on cover material bin be housed, discharge bucket is equipped with in the base bottom, at the cylinder lumen center main shaft is housed, main shaft is up and down by the rolling bearing and the thrust bearing positioning support that are contained in loam cake and the base, main shaft is equipped with a big belt pulley topmost, it is characterized in that: by the big belt wheel of small belt pulley on the belt connection motor and axle upper end, it also comprises the material casting dish, the crushing head body, the material casting dish is a disc, and there is axis hole at its center, and the disk surrounding is evenly equipped with a plurality of circular holes, the crushing head body is a short round platform, there is axis hole at the center, and several material casting dishes are housed on main shaft, between per two material casting dishes a plurality of crushing head bodies is housed.

The number that the crushing head body is installed on described per two material casting dishes can be 2～5, and these are installed in the crushing head body on the material casting dish, and constituting between planet crushing head body and the cylindrical shell is the position relation of several inscribed circles.

The oblique cone angle of described crushing head body is 20 °.

When driving central shaft after big or small pulley decelerates, motor rotates, several crushing head bodies revolve round the sun around main shaft, material drops on the cylindrical shell because of gravity from the top of cylindrical shell, be subjected to action of centrifugal force, thrown to the interior lining panel of cylindrical shell, at this moment the gap of amount liner plate is filled by material in crushing head body and the cylindrical shell, because the crushing head body is in revolution, certainly will form crushing head body roll extrusion simultaneously material and form rotation, make cone do planetary motion.Material because of gravity after impact roll extrusion through the crushing head body of several layers and cylindrical shell, form less powder shape discharge body.

The utility model has following advantage and effect compared with the prior art, and its compact conformation, volume is little, the ratio of reduction is big, low in energy consumption, metal effective rate of utilization height, expense are lower than existing disintegrating machine.Motion is steady, and noise is little.

Description of drawings:

Fig. 1 is a general assembly structure chart of the present utility model.

Fig. 2 is the A-A cutaway view of the general assembly structure chart of the disconnected type of this practicality.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: as shown in Figure 1, it is made up of material bin 1, material casting dish 2, motor 3, belt pulley 4, main shaft 5, bearing 6, cylindrical shell 7, crushing head body 8, discharge bucket 9, loam cake 10, base 11 and thrust bearing 12 etc.Wherein upthrow charging tray 2 is disks, and there is axis hole in central authorities, has on it a plurality of uniform circular holes are arranged on same diameter, main shaft 5 is multidiameters, and cylindrical shell 7 is cylindrical drums of steel, and crushing head body 8 is short Rotary-tables, there is axis hole at its center, and the tapering of Rotary-table is 20 ° of oblique angles; Discharge bucket 9 is flaring funnels, loam cake 10 is discs, there is boss at its center, connect many gussets around the boss, its center has can bearings mounted centre bore, and base 11 is discs, there is boss at the center, thrust bearing 12 and rolling bearing 6 are housed in its centre bore, and base is installed on the basis, and its lower bottom part is connected with hopper 9.Main shaft 5 is installed in the middle of the cylindrical shell 7, its upper and lower side is by the rolling bearing 6 and thrust bearing 12 positioning supports that are contained in loam cake 10 and the base 11, main shaft upper end is fixed with belt pulley 4 after passing the axis hole of loam cake 10, running part is connected by the belt pulley of belt with belt pulley 4 and motor, drive shaft 5 rotation at a high speed.A plurality of material casting dishes 2 are housed on the main shaft 5, and crushing head body 8 is installed between two parabolic dishes 2 by little axle, by rolling bearing little axle is connected with crushing head body 8, can be according to 2～5 crushing head bodies 8 of the uniform installation of centrifugal balance principle on the parabolic dish 2.Material enters the machine chamber through material bin 1, drops on the material casting dish 2, under the drive of motor 3, main shaft 5 high speed rotaries, material on the parabolic dish 2 is under centrifugal action, and the liner plate internal circle of being thrown to cylindrical shell 7 falls, and Fig. 1, Fig. 2 middle cylinder body 7 interior profile lines partly are liner plate.Because of crushing head body 8 revolve round the sun this moment, behind the chance material, because of material produces rotation in that radial velocity is almost nil, just be broken cone impact, roll extrusion of material like this.After several layers, discharge body from discharge bucket 9.The shattering process of material is just finished.
