Description
Technical field
The utility model belongs to crushing mechanism, relates in particular to a kind of fixed hydraulic breaker.
Background technology
The large-scale ore of mining is when concentrating second-time breakage; usually can run into the situation that feeding mouth is blocked by lump ore; and at present as the cycle cone crusher of coarse smash equipment, can't process timely and effectively this situation, had a strong impact on like this production efficiency.The cone crusher of cycle simultaneously needs to change liner plate in maintenance process, because gap of lining plate is less, general extracting tool is difficult for stretching into, therefore the dismounting liner plate is first to cut into a plurality of fritters with flame mostly at present, then rely on manpower that former liner plate is laid, the replacing time is at least more than 1 week, and lining plate replacing is more frequent, changed once in general about 3 months, so this kind replacing method has affected repair schedule.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of fixed hydraulic breaker with telescopic arm, and it has enlarged job area, is blocked in the lump ore of feeding mouth when can timely and effective processing concentrating second-time breakage, has improved production efficiency.Simultaneously, it is inner that it can also probe into the cycle cone crusher, hits liner plate, accelerated liner plate and removed speed, improved repair schedule.
A kind of fixed hydraulic breaker with telescopic arm of the utility model, comprise hydraulic system, electric control system, operating room, slewing equipment, rotary motor, rear swing arm, breaker, the first oil cylinder, the second oil cylinder and the 3rd oil cylinder, it is characterized in that: further comprising telescopic boom device, telescopic boom device comprises fixed arm, lever arm, telescopic oil cylinder; Lever arm is arranged in fixed arm, its inner chamber along fixed arm moves, and telescopic oil cylinder is arranged in lever arm and fixed arm, and is all hinged with both, the afterbody of fixed arm is hinged with rear swing arm, the second oil cylinder respectively, and the front portion of lever arm is hinged with the 3rd oil cylinder, breaker respectively.
Telescopic boom device motion principle during this is novel is: when telescopic oil cylinder stretched out, piston rod is fixing not to move with fixed arm, and lever arm is released in the cylinder head motion, and when telescopic oil cylinder was retracted, the cylinder barrel motion retracted lever arm.Hinged due to lever arm and the 3rd oil cylinder, breaker, move forward and backward so the 3rd oil cylinder promotes breaker under the effect of lever arm, thereby enlarged job area.Fixedly disintegrating machine of the present utility model is except the work that can complete conventional fixed crusher, cantilever arm can be stretched out where necessary, enlarge job area, probeing into physical features lower position finishes the work, therefore it can extend in feeding mouth, timely and effectively that the lump ore of feeding mouth is broken, thus the large-scale ore feeding mouth when concentrating second-time breakage that has solved mining by the situation that lump ore blocks, has improved production efficiency.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is the structural representation of this novel middle telescopic boom device;
Fig. 2 is the overall schematic of this Novel fixed-type disintegrating machine.
The specific embodiment
From Fig. 1, Fig. 2 as can be known, this novel a kind of fixed hydraulic breaker with telescopic arm, comprise hydraulic system 1, electric control system 2, operating room 3, slewing equipment 4, rotary motor 5, rear swing arm 6, breaker 10, the first oil cylinder 11, the second oil cylinder 7 and the 3rd oil cylinder 9, it also comprises telescopic boom device 8, and telescopic boom device 8 comprises fixed arm 13, lever arm 12, telescopic oil cylinder 14; Lever arm 12 is arranged in fixed arm 13, its inner chamber along fixed arm 13 moves, telescopic oil cylinder 14 is arranged in lever arm 12 and fixed arm 13, all hinged with both, the afterbody of fixed arm 13 is hinged with rear swing arm 6, the second oil cylinder 7 respectively, and the front portion of lever arm 12 is hinged with the 3rd oil cylinder 9, breaker 10 respectively.
Wherein, the cylinder head end 15 of telescopic oil cylinder 14 and the root of lever arm 12 are hinged, and its piston rod head 16 is hinged with the afterbody of fixed arm 13.
For lever arm 12 can be moved along the inner chamber of fixed arm 13, be provided with track between lever arm 12 and fixed arm 13: the track between lever arm 12 and fixed arm 13 can be slide block or guide plate.
Design principle of the present utility model is: hydraulic system 1 provides equipment required power, and the action of 2 pairs of equipment of electric control system is controlled, and detected pressures, oil temperature signal, and operating personnel operate in operating room 3.When telescopic oil cylinder 14 stretched out, piston rod is fixing not to move with fixed arm 13, and lever arm 12 is released in the cylinder head motion, has increased job area, and when telescopic oil cylinder 14 was retracted, the cylinder barrel motion retracted lever arm 12, has dwindled job area.The afterbody of fixed arm 13 and rear swing arm 6 are hinged, by stretching of the second oil cylinder 7, realize the folding of angle between telescopic boom device and rear swing arm 6; Rear swing arm 6 is hinged on slewing equipment 4, by stretching of the first oil cylinder 11, and the fluctuating of swing arm 6 after realizing; The front portion of lever arm 12 and breaker 10 are hinged, and the 3rd oil cylinder 9 promotes breaker 10 and moves forward and backward, thereby has enlarged job area.
Originally novel have the fixedly disintegrating machine of telescopic arm except the work that can complete conventional fixed crusher, where necessary, cantilever arm can be stretched out, enlarge job area, probeing into physical features lower position finishes the work, large-scale ore that can timely and effective processing mining feeding mouth when concentrating second-time breakage by the situation that lump ore blocks, has improved production efficiency.Simultaneously, it is inner that it can also probe into the cycle cone crusher, hits liner plate, accelerates liner plate and remove speed, improved repair schedule.
Therefore, this Novel fixed-type disintegrating machine has solved the problem that original fixed crusher has to maximize in order to complete the larger operating mode of fraction job area, overcome the fixing limitation of original disintegrating machine working range, can process neatly various operating modes, have the advantages that volume is little, job area is large.
