Abstract
The utility model provides a hydraulic protection jaw type crusher, and relates to crushing machinery for coarsely crushing steel slag. The hydraulic protection jaw type crusher comprises a jaw type crusher main machine, a hydraulic system and an electric control system, wherein the jaw type crusher main machine is internally provided with an elbow plate for adjusting the size of a material outlet arranged at the lower part of a crushing cavity, a piston shoes body and a hydraulic cylinder, the piston shoes body is connected with a piston rod of the hydraulic cylinder, the elbow plate is supported between the lower part of a movable jaw of the crusher and the piston shoes body, the hydraulic system is further internally provided with a pressure sensor for detecting the pressure in a high-pressure cavity of the hydraulic cylinder, a signal output end of the pressure sensor is connected with an electronic control system, and the electronic control system controls the work of the hydraulic cylinder through a hydraulic system. According to the hydraulic protection jaw type crusher, the problem that the common jaw type crusher cannot realize the automatic withdrawing protection and the continuous crushing work when encountering objects which cannot be crushed can be solved, and the production efficiency can be greatly improved.
Description
Technical field
The utility model relates to a kind of slag coarse crushing operation crushing mechanism of metallurgy industry, specifically a kind of hydraulic protecting jaw crusher.
Background technology
Metallurgical steel slag is the waste residue that produces in steel mill's steelmaking process, the large (1～2m of its granularity
3), and mix in the slag a large amount of scrap iron and steels is arranged, in order to recycle the scrap iron and steel that to smelt, adopt at present common jaw crusher to carry out coarse crushing processing, because the heavy scrap iron dust that includes of slag can not broken thing, often occurs the problems such as vexed car, machine breakdown in shattering process, can not normally produce, cause large steel slag to pile up, reclaim difficulty.
The utility model content
For addressing the above problem, the utility model provides a kind of hydraulic protecting jaw crusher, it contain more can not the crushing circuit of broken thing in, the off-load in the time of realizing automatic pulverizing, overload and the continuous crushing operation that resets.
For achieving the above object; the technical solution of the utility model is: a kind of hydraulic protecting jaw crusher; comprise the jaw crushing machine host; hydraulic system and electric-control system; be provided with in the jaw crushing machine host for the bracket of adjusting crusher chamber bottom discharge gate size; piston shoes body and hydraulic cylinder; the piston shoes body is connected with the piston rod of hydraulic cylinder; bracket is supported between broken motor-driven jaw bottom and the piston shoes body; in hydraulic system, also be provided with the pressure sensor for detection of hydraulic cylinder high pressure chest internal pressure; the signal output part of pressure sensor is connected with electric-control system, and electric-control system is by the work of HYDRAULIC CONTROL SYSTEM hydraulic cylinder.
Beneficial effect: the utility model has been established a pressure sensor for detection of the pressure in the hydraulic cylinder in hydraulic system, run in the course of the work can not broken thing the time when disintegrating machine like this, pressure in the hydraulic cylinder can raise, after reaching the setting value of sensor, pressure signal is reacted to electric-control system, and then adjust hydraulic system to the voltage supply situation of hydraulic cylinder, the final size that changes disintegrating machine lower end discharge gate, can not discharge crusher chamber by broken thing, afterwards, disintegrating machine recovers normal operation, whole process implementation automatic pulverizing, the off-load during overload and the continuous crushing operation that resets particularly can ensure continuously normal production of disintegrating machine in the coarse crushing operation of steel mill's slag crushing, increase substantially production efficiency, realized energy-saving and emission-reduction and the twice laid of metallurgical steel slag.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Be labeled as among the figure: 1, hydraulic system, 2, electric-control system, 3, crusher chamber, 4, moving jaw, 5, bracket, 6, the piston shoes body, 7, hydraulic cylinder, 8, fixed jaw, 9, sewing jaw, 10, frame.
The specific embodiment
In conjunction with Fig. 1 the utility model is further elaborated; a kind of hydraulic protecting jaw crusher; comprise jaw crushing machine host, hydraulic system 1 and electric-control system 2, be provided with fixed jaw 8, sewing jaw 9, frame 10, moving jaw 4, bracket 5, piston shoes body 6 and hydraulic cylinder 7 in the jaw crushing machine host.Sewing jaw 9 is installed on the moving jaw 4, and fixed jaw 8 is installed on the frame 10, and fixed jaw 8 consists of crusher chamber 3 with the left and right liner plate of sewing jaw 9 and frame medial surface, and the upper end of crusher chamber 3 is charging aperture, and the lower end is discharge gate.The cylinder body of hydraulic cylinder 7 is fixed on the crusher frame 10, and is connected with hydraulic system 1 by hydralic hose, and piston shoes body 6 is connected with the piston rod of hydraulic cylinder 7, and bracket 5 is supported between moving jaw 4 bottoms and the piston shoes body 6.By stretching of piston rod in the hydraulic cylinder 7, promotion or yielding piston shoes body 6, bracket 5 and moving jaw 4 move, thereby the yielding hydraulic pressure that realization works and " crossing iron " overloads is protected automatically.
In order to realize that hydraulic pressure protects automatically, in hydraulic system 1, be provided with the pressure sensor for detection of hydraulic cylinder 7 high pressure chest internal pressures, the signal output part of pressure sensor is connected with electric-control system 2, and electric-control system 2 is by the work of hydraulic system 1 control hydraulic cylinder 7.By the flexible automatic control of piston rod in electric-control system 2,1 pair of hydraulic cylinder 7 of hydraulic system, make hydraulic cylinder 7 carry out overload protection as a kind of hydraulic pressure overload protective supporting arrangement to disintegrating machine.
In the disintegrating machine course of normal operation; the motion of moving jaw 4 is to drive eccentric shaft by the driving section to rotate and produce; eccentric shaft drives moving jaw 4 as connecting rod as the crank of quadric chain; and the bracket 5 that drives thus as rocking bar swings; moving jaw 4 is done the compound movement (movement locus is for oval) that is conducive to fragmentation and discharge in the restriction at two ends; when can not broken thing entering crusher chamber 3 when causing the disintegrating machine overload; hydraulic cylinder 7 interior operating pressures raise; when reaching pressure sensor setting value overload protection force value; sensor sends signal to electric-control system 2; electric-control system 2 and then indicator solution pressing system 1 make hydraulic cylinder 7 high pressure chest releases; the piston rod of hydraulic cylinder 7 shrinks moving jaw 4 off-loads of drive and retreats; until can not be broken after thing discharges crusher chamber 3; hydraulic cylinder 7 high pressure chests are pressurized to rapidly operating pressure; moving jaw 4 sets back, and disintegrating machine normally moves work, has so just realized the automatic pulverizing of disintegrating machine; off-load during overload and the continuous crushing operation that resets.
