Description
Technical Field
The utility model relates to the field of machinary, a jaw breaker specifically says so, more specifically says an adjusting device of bin outlet.
Background
The inner side of the machine body of the old jaw crusher is provided with a fixed jaw plate, the front of a movable jaw is provided with a convex arc-shaped movable jaw plate, the two jaw plates form a wedge-shaped crushing cavity, the upper end of the movable jaw is hung on an eccentric shaft, the two ends of the eccentric shaft are supported on a rack, and when the eccentric shaft rotates, the movable jaw extrudes, splits and bends materials to crush. When hard materials are blocked, the movable jaw cannot automatically drive the movable jaw plate to loosen, the toggle plate must be detached, the toggle plate is installed in the fixed adjusting seat, the user wants to take off the toggle plate, the user is very arduous, and the user can only take off the toggle plate to loosen the movable jaw plate and remove foreign matters. To adjust the size of the discharge opening, the adjustment is carried out only by changing the length of the toggle plate, which is very troublesome and unsafe.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model aims at providing an adjustable structure of bin outlet, concrete technical scheme is as follows:
a jaw crusher structure capable of quickly adjusting the size of a discharge hole at any time comprises a crusher body, a fixed jaw plate is arranged on the inner side of the crusher body, a movable jaw is arranged on the opposite side of the fixed jaw plate, a movable jaw plate is arranged on the movable jaw, the fixed jaw plate and the movable jaw plate form a wedge-shaped crushing cavity, the upper end of the movable jaw is hung on an eccentric shaft, and the lower part of the crushing cavity is a discharge hole; the lower part of the movable jaw is connected with one end of a toggle plate, the other end of the toggle plate is connected with a toggle plate seat, and the toggle plate seat is connected with a piston of a hydraulic cylinder; the hydraulic cylinder is fixed on the frame.
The two ends of the toggle plate are provided with T-shaped ends, the toggle plate seat is provided with corresponding T-shaped grooves, and the T-shaped ends are respectively arranged in the T-shaped grooves of the toggle plate seats at the two ends; one of the toggle plate seats is fixed with the movable jaw through a bolt.
And a base plate is arranged in the T-shaped groove.
The bracket plate is provided with a guide bulge, the guide bulge is arranged in a positioning sleeve, and the positioning sleeve is fixed on the rack.
The hydraulic cylinder is connected with the hydraulic station through an electromagnetic directional valve, and a pressure gauge is arranged on a hydraulic pipeline.
The utility model has the advantages that: the hydraulic cylinder is used for adjusting the size of the discharge opening, and the operation is convenient and fast. Especially when the hard object which cannot be broken blocks is blocked and exceeds the set pressure value of the hydraulic cylinder, the pointer of the electric contact pressure gauge sends a signal to stop the electric contact pressure gauge, and meanwhile, a withdrawing signal is sent to the electromagnetic directional valve, and the piston rod retracts. Meanwhile, the movable jaw is driven to move backwards, so that the gap between the movable jaw and the fixed jaw is increased, namely, the discharge opening is increased, foreign matters are rapidly removed, and production is recovered. The structure protects the equipment, and has reliable work and convenient installation and disassembly; saves more time and labor, greatly reduces the crushing and manufacturing cost and improves the yield.
Drawings
Fig. 1 is a schematic structural view of the present invention;
figure 2 is a schematic view of the connection of the toggle plate to the movable jaw and the hydraulic cylinder.
Detailed Description
The utility model is described in detail with the following drawings, as shown in the figures, the utility model comprises a crusher body 1, a fixed jaw plate 2 is arranged at the inner side of the crusher body 1, a movable jaw 4 is arranged at the opposite side of the fixed jaw plate 2, a movable jaw plate 3 is arranged at the movable jaw, the fixed jaw plate 2 and the movable jaw plate 3 form a wedge-shaped crushing cavity, the upper end of the movable jaw 4 is hung on an eccentric shaft 13, and the lower part of the crushing cavity is a discharge opening 14; the lower part of the movable jaw 4 is connected with one end of a toggle plate 5, the other end of the toggle plate 5 is connected with a toggle plate seat 7, and the toggle plate seat 7 is connected with a piston of a hydraulic cylinder 9 through a positioning pin 8; the hydraulic cylinder 9 is fixed on the frame 1.
The two ends of the toggle plate 5 are provided with T-shaped ends 51, the toggle plate seat 7 is provided with corresponding T-shaped grooves 71, and the T-shaped ends 51 are respectively arranged in the T-shaped grooves 71 of the toggle plate seats at the two ends; one toggle plate seat 7 and the movable jaw 4 are fixed through a bolt 12. The T-shaped end 51 slides in the T-shaped slot 71, ensuring that the toggle plate does not interfere with the rotation of the movable jaw 4 when it is extended or retracted.
In order to facilitate maintenance and replacement, a backing plate 6 is arranged in the T-shaped groove.
For accurate positioning, the toggle plate is provided with a guide bulge 52, the guide bulge 52 is arranged in the positioning sleeve 10, and the positioning sleeve 10 is fixed on a machine frame.
The hydraulic cylinder is connected with the hydraulic station through an electromagnetic directional valve, and a pressure gauge is arranged on a hydraulic pipeline.
When the discharge opening needs to be reduced, the hydraulic station supplies oil to the hydraulic cylinder 9 to push the piston rod to extend out, so that the movable jaw assembly 4 is driven to move forwards, the movable jaw plate 3 is driven to move forwards, the gap between the movable jaw plate 3 and the fixed jaw plate 2 is reduced, and the discharge opening is reduced. When the discharge opening needs to be increased, the hydraulic station supplies oil to the hydraulic cylinder 9, the piston rod is pushed to retract, and meanwhile, the movable jaw assembly 4 is driven to move backwards, so that the movable jaw plate 3 is driven to move backwards, at the moment, the gap between the movable jaw plate 3 and the fixed jaw plate 4 is increased, and the discharge opening is increased. The structure is controlled by hydraulic pressure, and the size of the discharge port can be adjusted at any time.
