Abstract

The invention discloses a cone coal crusher, which is characterized in that the external surface of a movable cone is fixed with a movable cone liner plate with a spiral blade; a swaying cone liner plate is fixed on a swaying cone; the upper end of a spring supports the swaying cone and the lower end of the spring is stressed on a frame; the swaying frame is arranged in a rotary big gear, and the rotary big gear is fixed with a lug; the lug is arranged against a rail surface of the swaying cone; the inner ring of the rotary big gear is fixed on a support rod of the rotary big gear; the support rod of the rotary big gear is fixed on the frame; the frame is fixed with a hopper, the outlet of which is opposite to the movable cone; the swaying cone is articulated with the frame and fixed with a location-limiting block; the location-limiting block is arranged against a location-limiting rod, and the location-limiting rod is fixed on the frame; a motor drives the gears to drive the main shaft and the rotary big gear by the engagement of a first motor main shaft bevel gear and a main shaft bevel gear, and a second motor shaft bevel gear and a secondary shaft bevel gear; and an eccentric shaft is fixed on the main shaft. The invention solves the problem completely that the traditional coal crusher is easily blocked when crushing the crude coal; meanwhile, the synchronous cone coal crusher has high crushing efficiency and good crushing effect and can increase the crushing force.

Description

Synchronous cone coal crusher

Technical field:

The present invention relates to the disintegrating machine technical field, more specifically to a kind of gyratory crusher that is used for the raw coal fragmentation.

Background technology:

The ZL patent No. 92248443.6 discloses a kind of screw-pushing type gyratory crusher, it is made up of mantle liner plate, spiral cover, mantle, eccentric shaft and the transmission system of rolling awl, band spiral, this machine is when broken raw material, utilize spiral that raw material is advanced, because of clogging not occurring a bit, be particularly suitable for the higher raw material of broken moisture content.Its weak point is: when the broken raw material, because the raw coal moisture content is higher, still have part material to be bonded on the spiral cover with this machine, cause and stop up.Simultaneously, its crushing efficiency is lower.

Summary of the invention:

Purpose of the present invention is exactly the deficiency at prior art, and a kind of synchronous cone coal crusher is provided, the problem of blockage phenomenon when it thoroughly solves the raw coal fragmentation, and the crushing efficiency height has increased crushing force simultaneously, and crushing effect is good, finished granule rate height.

Technology solution of the present invention is as follows:

Synchronous cone coal crusher, comprise rolling awl and be assemblied in mantle on the eccentric shaft, the mantle outer surface is fixed with the mantle liner plate of band flight, and rolling awl liner plate is fixed on the rolling awl, and the rolling awl is being supported in the spring upper end, spring lower end active force is on frame, the rolling awl places the revolution gear wheel, is fixed with projection on the revolution gear wheel, and projection resists on the orbital plane of rolling awl, revolution gear wheel inner ring is fixed on the revolution gear wheel support bar, and revolution gear wheel support bar is fixed on the frame;

Be fixed with hopper on the frame, hopper outlet is facing to mantle, and the rolling awl is hinged on the frame, is fixed with limited block on the rolling awl, and limited block resists on gag lever post, and gag lever post is fixed on the frame;

Be fixed with the first motor shaft bevel gear on the electric machine main shaft, the first motor shaft bevel gear is meshed with main shaft bevel gear on being fixed on main shaft, be fixed with the second motor shaft bevel gear on the motor, the second motor shaft bevel gear is meshed with the auxilliary axial cone gear that is fixed on auxilliary, be fixed with driven wheel on the auxilliary axle, driven wheel is meshed with the revolution gear wheel, and eccentric shaft is fixed on the main shaft.

Described eccentric shaft top is fixed with material separating disc.

Beneficial effect of the present invention is:

1, when mantle rotates, the rolling awl adds swing ceaselessly rocking, and the higher raw coal of moisture content just can not bond to rolling and bores on the liner plate like this.Simultaneously, because mantle and the soft property of rolling awl are strong, make lump coal finished granule rate height.

2, in design, projection axis and mantle stretch out maximum direction and remain on 90～120 degree, and the coal cinder that assurance is bigger can both enter all the time the mantle liner plate of being with flight from all directions and be broken like this, has improved crushing efficiency.

3, raw coal has been subjected to the effect of mantle with rolling awl two-way function power when fragmentation, compared with prior art, has increased the crushing force to raw coal, and crushing effect is good, and gentle force is strong.

Description of drawings:

Fig. 1 is a structural representation of the present invention;

Fig. 2 is the annexation schematic perspective view of revolution gear wheel with the rolling awl.

The specific embodiment:

Embodiment: see shown in Fig. 1,2 that synchronous cone coal crusher comprises rolling awl 1 and the mantle 3 that is assemblied on the eccentric shaft 2, mantle 3 outer surfaces are fixed with the mantle liner plate 4 of band flight, and rolling awl liner plate 6 is fixed on the rolling awl 1, and rolling awl 1 is being supported in spring 8 upper ends, spring 8 lower end active forces are on frame 5

Rolling awl 1 places revolution gear wheel 9, is fixed with projection 10 on the revolution gear wheel 9, and projection 10 resists on 102 on the track of rolling awl 1, and revolution gear wheel 9 inner rings are fixed on the revolution gear wheel support bar 11, and revolution gear wheel support bar 11 is fixed on the frame 5;

Be fixed with hopper 12 on the frame 5, hopper 12 outlets are facing to mantle 3, and rolling awl 1 is hinged on the frame 5, is fixed with limited block 101 on the rolling awl 1, and limited block 101 resists on gag lever post 13, and gag lever post 13 is fixed on the frame 5;

Be fixed with the first motor shaft bevel gear 17 on motor 14 main shafts, the first motor shaft bevel gear 17 is meshed with main shaft bevel gear 16 on being fixed on main shaft 15, be fixed with the second motor shaft bevel gear 19 on the motor 14, the second motor shaft bevel gear 19 is meshed with the auxilliary axial cone gear 18 that is fixed on auxilliary 21, be fixed with driven wheel 20 on the auxilliary axle 21, driven wheel 20 is meshed with revolution gear wheel 9, and eccentric shaft 2 is fixed on the main shaft 15.
