Description

Movable crusher

Technical field:

The utility model relates to a kind of engineering with machinery, relates in particular to the movable crusher that bulk materials is carried out second-time breakage.

Background technology

In underground mining and tunnel excavating process, because of producing some bulk materials (as: ore, rock etc.), explosion make scraper be difficult to shovel dress, transportation, need carry out artificial rock drilling and second-time breakage processing to bulk materials usually.Second-time breakage has not only increased cost of mining, has made workman's manual labor heavy, and if in case miso-fire occurs and also will bring hidden danger to personnel, equipment.

Summary of the invention

Problem to be solved in the utility model provides a kind of movable crusher, and it can carry out second-time breakage to the bulk materials that produces in underground exploitation, the tunnel excavating process, thereby replaces artificial rock drilling, secondary blasting.

Movable crusher of the present utility model is made up of chassis portion and operating mechanism, it is characterized in that: operating mechanism comprises left-right swinging mechanism, swing arm rotating mechanism, two arm rotating mechanisms, hydraulic hammer rotating mechanism; Left-right swinging mechanism comprises oil cylinder, swing span, swing seat, sphere oscillating bearing; The two ends of oil cylinder are hinged by bearing pin and swing seat, swing span respectively; Between the top of swing span and swing seat the sphere oscillating bearing is installed, the outer ring of bearing is connected with swing span, and its inner ring is connected with swinging by rotating shaft.

The swing arm rotating mechanism comprises boom cylinder, swing arm; Boom cylinder one end is hinged by bearing pin and swing span, and the other end is hinged by bearing pin and swing arm; Swing arm is hinged by bearing pin and swing span.Two arm rotating mechanisms comprise two arm oil cylinders, two arms; Two arm oil cylinders, one end is hinged by bearing pin and swing arm, and the other end is hinged by bearing pin and two arms; Two arms are hinged by bearing pin and swing arm.The hydraulic hammer rotating mechanism comprises changes hammer oil cylinder, hydraulic hammer; Commentaries on classics hammer oil cylinder one end is hinged by bearing pin and two arms, the other end is hinged by bearing pin and hydraulic hammer; Hydraulic hammer is hinged by bearing pin and two arms.

The utility model can swing by flexible swing span, swing arm, two arms, the hydraulic hammer realized of passing ratio control oscillating oil cylinder, and pendulum angle is α.This novel also passing ratio control simultaneously boom cylinder, two arm oil cylinders, commentaries on classics hammer oil cylinder rotate and realize that swing arm, two arms, hydraulic hammer rotate around bearing pin, and working range is (A+B) up and down, and the front and back working range is C.The operative employee handle ratio control handle realize before and after swing arm, two arms, the hydraulic hammer, up and down, the comprehensive captured target in the left and right sides implements brokenly, make that bulk materials is crushed to below 0.5 cubic metre more than 1 cubic metre, thereby be convenient to scraper shovel dress, transportation.Because the utility model can be realized four degree of freedom compound motions at the underground job maneuverability, and have that job area is wide, advantage such as accurate positioning, breaking capacity are big, operating efficiency height, therefore artificial rock drilling, second-time breakage have been replaced, production efficiency significantly improves, reduced blasting cost, alleviate heavy manual labor simultaneously, overcome hidden danger.

The specific embodiment

From Fig. 1, Fig. 3, Fig. 4, Fig. 5 as can be known, the movable crusher that this is novel is made up of chassis portion 1 and operating mechanism 2, and it is characterized in that: operating mechanism 2 comprises left-right swinging mechanism, swing arm rotating mechanism, two arm rotating mechanisms, hydraulic hammer rotating mechanism; Left-right swinging mechanism comprises oil cylinder 12, swing span 5, swing seat 3, sphere oscillating bearing 28; The two ends of oil cylinder 12 are hinged by bearing

20,21 and swing 3, swing span 5 respectively; Between the top of swing span 5 and swing seat 3 sphere oscillating bearing 28 is installed, the outer ring 18 of bearing is connected with swing span 5, its inner ring 19 by rotating shaft 15 with swing 3 and be connected.

From Fig. 1, Fig. 3 as can be known, the swing arm rotating mechanism comprises boom cylinder 6, swing arm 7; Boom cylinder 6 one ends are hinged by bearing pin 22 and swing span 5, and the other end is hinged by bearing pin 23 and swing arm 7; Swing arm 7 is hinged by bearing pin 4 and swing span 5.Two arm rotating mechanisms comprise two arm oil cylinders 8, two arms 9; Two arm oil cylinders, 8 one ends are hinged by bearing pin 24 and swing arm 7, and the other end is hinged by bearing pin 25 and two arms 9; Two arms 9 are hinged by bearing pin 16 and swing arm 7.The hydraulic hammer rotating mechanism comprises changes hammer oil cylinder 10, hydraulic hammer 11; Change hammer oil cylinder 10 1 ends by bearing pin 26 is 9 hinged with two arms, the other end is hinged by bearing pin 27 and hydraulic hammer 11; Hydraulic hammer 11 is hinged by bearing pin 17 and two arms 9.

As can be seen from Figure 2, the chassis portion 1 of the utility model movable crusher is fixedlyed connected with the swing span 3 of operating mechanism 2 by its front frame 15; Chassis portion 1 comprises transmission system 13 and hydraulic system 14; The chassis 01 of dynamic formula crushing engine running gear is adopted and is selected the scraper chassis for use, promptly hinged, suspension type chassis, adopt emission control diesel or motor as power, by transmission system 013 (comprising fluid torque-converter, Powershift transmission, power transmission shaft, differential mechanism, hub reduction gear etc.) thus be implemented in the light operation of the scope of operation that condition of work is abominable, operation field is narrow, short and muddy, even running.

Operating personnel reach this novel movable crusher near the big stone, the hydraulic pressure leg is propped up, manipulation ratio control handle realizes before and after swing arm, two arms, the hydraulic hammer, up and down, the comprehensive captured target in the left and right sides implements broken, the working range up and down of whole operating mechanism is (A+B), the front and back working range is C (as shown in Figure 6), the angle that swings is α (as shown in Figure 7), makes that bulk materials is crushed to below 0.5 cubic metre more than 1 cubic metre, thereby is convenient to scraper shovel dress, transportation.Because the utility model can be realized four degree of freedom compound motions at the underground job maneuverability, and have that job area is wide, advantage such as accurate positioning, breaking capacity are big, operating efficiency height, therefore artificial rock drilling, second-time breakage have been replaced, production efficiency significantly improves, reduced blasting cost, alleviate heavy manual labor simultaneously, overcome hidden danger.
