Abstract

The utility model relates to a screw propelling type cone crusher, which is used for crushing raw materials in the industries, such as the manufacture of building materials, the chemical industry, the metallurgy, the coal, the mining, etc. The utility model is characterized in that the screw propelling type cone crusher is composed of a fixed cone, a moving cone lining board with a screw, a spiral pressing cover, a moving cone, an eccentric shaft, a transmission system, etc. When the raw materials are crushed, the screw propelling type cone crusher can propel the raw materials through making use of the screw. Accordingly, the blocking phenomenon can not be generated; the condition is particularly favorable to crush the raw materials with higher crushing water content and greater viscosity, and the raw materials can be combined with the stirring function and the mixing function. Meanwhile, the internal part of the transmission system adopts a rolling bearing, and accordingly, the screw propelling type cone crusher has simple structure.

Description

Screw propelling type cone crusher

The utility model relates to and use the broken of gyratory crusher or gyratory crusher and pulverize specifically a kind of screw-pushing type gyratory crusher.

The gyratory crusher that uses all is made of mantle and fixed awl at present, the mantle of being used as the swing campaign periodically near or leave when deciding poppet surface, the raw material that enters in the crusher chamber constantly is squeezed and flecition and fragmentation, the raw material that has been broken is discharged from two cone bases by own wt, but, if chance raw material moisture content is higher or viscosity is bigger, clogging then appears easily, reduced productivity ratio.

The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of forced conveyance raw material that has is provided, and clogging can not occur, and have the screw-pushing type gyratory crusher of effect that raw material is mixed concurrently.

The purpose of this utility model can reach by following measure:

A kind of screw-pushing type gyratory crusher, comprise and be fixed in deciding awl 2 and being assemblied in mantle 7 on the eccentric shaft 12 on the frame, its special ripe part is, the vaned mantle screw lining board 8 of mounting strap on mantle 7 outer surfaces, do with being fixed on the awl liner plate of deciding on awl 2 inner surfaces 9 of deciding that eccentric screw propulsion is broken to be cooperated, the mantle 7, spiral cover 6, the lock nut 5 that are installed on the eccentric shaft 12 are located on the bearing sleeve 16 by self-aligning roller bearing 10 and thrust bearing 17.

Spiral cover 6 of the present utility model can be provided with single line or multi-thread continuous helical blade face with mantle screw lining board 8.

The utility model can also be at eccentric shaft 12 middle parts assembling large conical gear 19, and by rolling bearing assembling power transmission shaft 21, the end assembling belt pulley 18 of power transmission shaft 21, other end are fixed with small conical gear 20 and large conical gear 19 engagements in the drive shaft mount 22.

Accompanying drawing and description of drawings:

Fig. 1 is the utility model cross-sectional view.

Fig. 2 is the another kind of drive mechanism part section of a utility model structural representation.

Among the figure: the 1-splicing sleeve, 2-bores surely, 3-funnel, 4-material separating disc; the 5-lock nut, 6-spiral cover, 7-mantle, 8-mantle screw lining board; 9-bores liner plate surely, 10-self-aligning roller bearing, 11-spring protection device, 12-eccentric shaft; the 13-gripper shoe, 14-frame, 15-basis, 16-eccentric shaft bearing sleeve; the 17-thrust bearing, 18-belt pulley, 19-large conical gear, 20-small conical gear; the 21-power transmission shaft, 22-drive shaft mount, 23-dumping pit.

The utility model is described in further detail below in conjunction with accompanying drawing embodiment:

As shown in Figure 1, bore 2 in the screw-pushing type gyratory crusher surely and cast by screw thread for cast iron or cast steel and to be connected, and be connected with frame 14, be seated on the basis 15 of xoncrete structure through spring protection device 11 with splicing sleeve 1.Mantle 7 also is cast iron or cast steel, is connected with eccentric shaft 12 with key, and mantle screw lining board 8 is formed by casting, is fixed by bolt and mantle 7.Spiral cover 6 usefulness keys are connected with eccentric shaft 12, to 8 pressuring actions of mantle screw lining board.5 pairs of spiral covers 6 of lock nut and mantle 7 have locking effect, and make its unlikely generation axial float.Material separating disc 4 usefulness bolts and eccentric shaft 12 are fixing, mantle 7, mantle screw lining board 8, spiral cover 6 and eccentric shaft 12 etc. are by the eccentric shaft bearing sleeve 16 of bottom, self-aligning roller bearing 10 and thrust bearing 17 support, and bear broken load by the combination of self-aligning roller bearing 10 and thrust bearing 17.On gripper shoe 13, weld with frame 14 is to have dumping pit 23 on the gripper shoe 13 of one to eccentric shaft bearing sleeve 16 by bolting, and spring protection device 11 connects together with frame 14 by long bolt and spring handle splicing sleeve 1.

The also available accompanying drawing 2 of transmission system replaces as shown in Figure 1, assemble with key and large conical gear 19 at eccentric shaft 12 middle parts, small conical gear 20 also is to be connected with power transmission shaft 21 with key, fixing small conical gear 20 and large conical gear 19 engagements, drive shaft mount 22 is connected with eccentric shaft bearing tube 16 with bolt on one side, and another side uses bolting on basis 15.Power transmission shaft 21 back fast pulleies 18.

The course of work of the present utility model is:

When motor drives belt pulley 18 rotations by belt, eccentric shaft 12 rotations, mantle 7 is made eccentric motion with eccentric shaft 12.Need broken raw material to fall earlier on the material separating disc 4, evenly fall in the funnel 3 through the material separating disc 4 of rotation again, enter the crusher chamber of deciding between awl liner plate 9 and the mantle screw lining board 8.One side of mantle 7 of being used as eccentric motion is near boring 2 o'clock surely, raw material is in and is extruded and broken state, screw propulsion by means of

spiral cover

6 and 8 pairs of raw materials of mantle screw lining board, the raw material that has been broken will be easy to discharge by the bottom discharge opening 23 of two cones, and the clogging of raw material in crusher chamber can not appear, also play simultaneously and stir and immixture.

Spring protection device 11 around the frame is safeties that the protection disintegrating machine is not damaged.When disintegrating machine is fallen into non-broken thing, increase because crushing force is anxious, spring is forced to compression, this moment splicing sleeve 1 and bore 2 surely and upwards lift together, mantle 7 and bore 2 surely between distance strengthen, thereby the non-broken thing fallen into is discharged, then splicing sleeve 1 and bore 2 surely and set back by the tension force of spring again through the discharge gate of mantle and fixed awl bottom.

Adjust bore surely 2 and mantle 7 between the distance size of promptly adjusting discharge gate be by means of bore surely 2 and the saw-tooth thread ascending, descending of 1 of splicing sleeve bore liner plate 9 surely and realize.In shattering process, do not produce up and down between buttless thread or the relative motion of circumferencial direction in order to make, at splicing sleeve 1 with bore 2 surely and lock stop device with bolting.

The utility model compared with prior art has the following advantages:

1, owing to set up spiral blade face forced conveyance raw material on the mantle surface, thereby not Clogging can occur, be conducive to the higher or greatly pulverizing of material of viscosity of broken moisture content, have simultaneously the function of Agitation and mixing raw material.

2, all adopted rolling bearing in the transmission system of the present utility model, thus simple in structure, be convenient to promote.
