Description
Technical field
The utility model relates to a kind of vertical crusher, particularly a kind of for vertical crushers such as powder ore, grounds travel, cereal.
Background technology
Vertical crusher is generally used for powder ore, grounds travel or cereal etc., and its operation principle is to be driven and pressed down ore by hydraulic cylinder, and driven by motor is pulverized hub rotation in pressing down, and further improves the effect of pulverizing.Existing pulverizer in running easily card machine, even cause burn-down of electric motor, be mainly because press down in process pulverizing hub, pulverize the load that is subject to of hub increasing, if now also with speed feeding before, just be easy to cause pulverizing hub stuck, even cause burn-down of electric motor.
Utility model content
The purpose of this utility model is, a kind of vertical crusher is provided.The utility model can effectively prevent motor overload and the equipment fault that causes, can improve crushing effect simultaneously.
The technical solution of the utility model: a kind of vertical crusher, described mechanical mechanism comprises 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, and the end of cantilever is provided with a motor, and the output of motor is provided with a main shaft, and the below of main shaft is connected with pulverizing hub, and pulverizing hub is placed in the top of crushing groove; Described hydraulic mechanism comprises oil pump, and oil pump is connected with a three position four-way electromagnetic valve through P oil circuit, and the A oil circuit of three position four-way electromagnetic valve is connected with the two ends of hydraulic cylinder respectively with B oil circuit, and the T oil circuit of three position four-way electromagnetic valve is connected with fuel tank; On described B oil circuit, be connected with a proportional velocity regulating valve, proportional velocity regulating valve is connected with a proportional valve control amplifier, and proportional valve control amplifier is connected with an electric controller, and electric controller is connected with motor through circuit.
In above-mentioned vertical crusher, described electric controller is current transformer.
In aforesaid vertical crusher, on described P oil circuit, be also connected with an overflow valve.
Compared with prior art, the utility model is by being arranged on proportional velocity regulating valve on the B oil circuit of hydraulic mechanism and the FEEDBACK CONTROL between electric controller, electric controller detects the phase current of motor, be depressed into and to a certain degree make to pulverize hub and rotate when slack-off when pulverizing hub, the phase current of motor changes, electric controller picked up signal control ratio flow speed control valve carry out speed governing, reduce the feed speed that presses down of hydraulic cylinder, thereby change the rotary load of pulverizing hub, avoid the equipment fault causing due to overload, the utility model also can ensure to pulverize hub all the time with certain rotating speed rotation simultaneously, ensure crushing effect.
