Description
[technical field]
The utility model relates to the technical field of thrust mechanism, particularly a kind of gyratory crusher technical field of convex surface formula thrust mechanism.
[background technology]
Gyratory crusher is applicable to metallurgy, builds, builds the road, the fragmentation of chemistry and silicate industry Raw, varies in size, be divided into again a lot of model according to the difference of smashing principle and magnanimity product particle.Disintegrating machine is widely used in numerous departments such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry.Cone crushing ratio is large, efficiency is high, energy consumption is low, and product granularity is even, broken and various ore in small, broken bits in being applicable to, rock.In the course of work of gyratory crusher, motor drives eccentric bushing to rotate by transmission device, mantle excentric sleeve forced to move under do rotary oscillation, namely mantle becomes crusher chamber near the section of quiet cone, and material is subject to the repeatedly extruding of mantle and quiet cone and shock and broken.Thrust mechanism is the important mechanism in gyratory crusher, and existing thrust mechanism adopts bi-concave structure, and difficulty of processing is large, and cost of manufacture is higher, unfavorable with promote the use of.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, a kind of gyratory crusher convex surface formula thrust mechanism is proposed, the upper surface of middle thrust plate is arc convex structure, lower surface is planar structure, and reduce the processing cost of middle thrust plate, save the manufacturing cost of equipment, be convenient to the popularization of equipment.
For achieving the above object, the utility model proposes a kind of gyratory crusher convex surface formula thrust mechanism, comprise main shaft, contiguous block, upper thrust plate, middle thrust plate, lower thrust plate and piston body, described main shaft is connected with contiguous block, thrust plate is provided with below contiguous block, middle thrust plate is placed with below upper thrust plate, lower thrust plate is provided with below middle thrust plate, described piston body is installed on the lower end of lower thrust plate, the upper surface of described middle thrust plate is arc convex structure, the lower surface of middle thrust plate is planar structure, the lower surface of upper thrust plate is arc-shaped concave structure, described arc convex structure and arc-shaped concave respective outer side edges are installed.
As preferably, the top and bottom of described contiguous block are respectively equipped with upper process block and lower process block, and contiguous block is coordinated with main shaft end by upper process block to be installed, and contiguous block passes through lower process block and coordinates with upper thrust plate and installs.
As preferably, described lower thrust plate is connected with piston body by alignment pin, is provided with lubricant channel in described piston body.
Described middle thrust plate coordinates installation place to be provided with some grooves with upper thrust plate, and middle thrust plate coordinates installation place to be provided with some grooves with lower thrust plate.
The beneficial effects of the utility model: the upper surface of middle thrust plate of the present utility model is arc convex structure, lower surface is planar structure, in addition the relative motion in can reducing between thrust plate lower surface and lower thrust plate upper surface, the frictional force of thrust mechanism is less, and reduce the processing cost of middle thrust plate, save the manufacturing cost of equipment, be convenient to the popularization of equipment.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the main TV structure figure of a kind of gyratory crusher of the utility model convex surface formula thrust mechanism;
Fig. 2 is the structural representation of the utility model groove.
[detailed description of the invention]
Consult Fig. 1 and Fig. 2, a kind of gyratory crusher convex surface formula thrust mechanism of the utility model, comprise main shaft 1, contiguous block 2, upper thrust plate 3, middle thrust plate 4, lower thrust plate 5 and piston body 6, described main shaft 1 is connected with contiguous block 2, thrust plate 3 is provided with below contiguous block 2, middle thrust plate 4 is placed with below upper thrust plate 3, lower thrust plate 5 is provided with below middle thrust plate 4, described piston body 6 is installed on the lower end of lower thrust plate 5, the upper surface of described middle thrust plate 4 is arc convex structure 41, the lower surface of middle thrust plate 4 is planar structure, the lower surface of upper thrust plate 3 is arc-shaped concave structure 31, described arc convex structure 41 coordinates with arc-shaped concave structure 31 installs.
The top and bottom of described contiguous block 2 are respectively equipped with upper process block 21 and lower process block 22, contiguous block 2 is coordinated with main shaft 1 end by upper process block 21 to be installed, contiguous block 2 is coordinated with upper thrust plate 3 by lower process block 22 to be installed, described lower thrust plate 5 is connected with piston body 6 by alignment pin 7, lubricant channel 61 is provided with in described piston body 6, described middle thrust plate 4 coordinates installation place to be provided with some grooves 8 with upper thrust plate 3, and middle thrust plate 4 coordinates installation place to be provided with some grooves 8 with lower thrust plate 3.
Utility model works process:
A kind of gyratory crusher of the utility model with convex surface formula thrust mechanism in the course of the work, the upper surface of middle thrust plate 4 of the present utility model is arc convex structure 41, middle thrust plate 4 lower surface is planar structure, the lower surface of upper thrust plate 3 is arc-shaped concave structure 31, described arc convex structure 41 coordinates with arc-shaped concave structure 31 installs, middle thrust plate and upper thrust plate and lower thrust plate three can relative motions, in addition the frictional force that between middle thrust plate 4 lower surface and lower thrust plate 5 upper surface, relative motion produces is less, make the overall suffered frictional force of thrust mechanism less, and reduce the processing cost of middle thrust plate 4, save the manufacturing cost of equipment, be convenient to the popularization of equipment.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
