Description
Technical field
The present invention relates to a kind of vertical crusher, particularly a kind of for powder ore, grounds travel,
The vertical crushers such as corn.
Background technology
Vertical crusher is generally used for powder ore, grounds travel or corn etc., its operation principle
It is to be driven down by hydraulic cylinder to press Ore, and driven by motor pulverizes hub rotation while pressure down, enters
One step improves the effect pulverized.Existing pulverizer in running easy card machine, even lead
Causing burn-down of electric motor, be primarily due under pulverizing hub during pressure, the load that pulverizing hub is subject to is more
Come the biggest, if the most also with speed feeding before, just easily cause pulverizing hub stuck,
Even result in burn-down of electric motor.
Summary of the invention
It is an object of the invention to, it is provided that a kind of vertical crusher.The present invention can effectively prevent
Motor overload and the equipment fault that causes, can improve crushing effect simultaneously.
Technical scheme: a kind of vertical crusher, described mechanical mechanism includes chassis,
The top on chassis is frame, chassis bottom be workbench, workbench is provided with crushing groove；
The top of described frame is provided with a hydraulic cylinder, and the external part of hydraulic cylinder is provided with a cantilever, cantilever
End be provided with a motor, the outfan of motor is provided with a main shaft, and the lower section of main shaft connects powder
Broken hub, pulverizes hub and is placed in the top of crushing groove；Described hydraulic mechanism includes oil pump, oil pump warp
P oil circuit connects a three position four-way electromagnetic valve, the A oil circuit of three position four-way electromagnetic valve and B oil circuit
Being connected with the two ends of hydraulic cylinder respectively, the T oil circuit of three position four-way electromagnetic valve is connected with fuel tank；Institute
Connecting on the B oil circuit stated and have a proportional velocity regulating valve, proportional velocity regulating valve connects a proportional valve control
Amplifier, proportional valve control amplifier connects an electric controller, and electric controller is through circuit and motor phase
Even.
In above-mentioned vertical crusher, described electric controller is current transformer.
In aforesaid vertical crusher, described P oil circuit is also associated with an overflow valve.
Compared with prior art, the present invention is by being arranged on the ratio on the B oil circuit of hydraulic mechanism
Feedback control between flow speed control valve and electric controller, the phase current of electric controller detection motor, work as pulverizing
Hub is depressed into when to a certain degree making to pulverize hub slow its rotation, and the phase current of motor produces change,
Electric controller obtains signal and controls proportional velocity regulating valve and carry out speed governing, reduce be pressed under hydraulic cylinder to
Speed, thus change the rotary load pulverizing hub, it is to avoid the equipment that causes due to overload therefore
Barrier, the present invention also can guarantee that pulverizing hub rotates with certain rotating speed all the time simultaneously, it is ensured that pulverizes effect
Really.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the schematic diagram of hydraulic mechanism of the present invention.
Detailed description of the invention
Below in conjunction with embodiment, the present invention is described in further detail, but not as to this
Bright restriction.
Embodiment: a kind of vertical crusher, as shown in Figures 1 and 2, including mechanical mechanism and
Hydraulic mechanism, described mechanical mechanism includes that chassis 1, the top on chassis 1 are frame 2, the end
The bottom of the 1 of dish is workbench 3, and workbench 3 is provided with crushing groove 4；Described frame 2
Top be provided with a hydraulic cylinder 5,5 external parts of hydraulic cylinder are provided with a cantilever 6, cantilever 6
End is provided with a motor 7, and the outfan of motor 7 is provided with a main shaft 8, and the lower section of main shaft 8 connects
It is connected to pulverize hub 9, pulverizes hub 9 and be placed in the top of crushing groove 4；Described hydraulic mechanism includes
Oil pump 12, oil pump 12 connects through P oil circuit a three position four-way electromagnetic valve 13,3-position 4-way electricity
Four paths of magnet valve are respectively P, T, A and B oil circuit, the A of three position four-way electromagnetic valve 13
Oil circuit and B oil circuit two ends with hydraulic cylinder 14 respectively are connected, the T of three position four-way electromagnetic valve 13
Oil circuit is connected with fuel tank；Connecting on described B oil circuit and have a proportional velocity regulating valve 15, ratio is adjusted
Speed valve can be electro-hydraulic proportional throttle valve, and proportional velocity regulating valve 15 connects has a proportional valve control to put
Big device 16, proportional valve control amplifier 16 connects an electric controller 17, and electric controller 17 is through electricity
Road is connected with motor 7.Described electric controller 17 is current transformer.On described P oil circuit
It is also associated with an overflow valve 10.Described proportional valve control amplifier is by the motor received
Phase current changes, then comparative example flow speed control valve provides specific currents, thus regulates proportional velocity regulating valve
Flow velocity, then the feed speed of hydraulic cylinder is adjusted, described proportional valve control amplifier can
With by commercially available acquisition, therefore concrete structure is not repeating at this.
