The present invention relates to the snow cave shovel of snow shoveling machine, especially with the snow cave shovel device of heating function.
Background technology
At present, the snow cave shovel major part of snow shoveling machine does not have heating function, and snow cave shovel, after extensive work, easily forms sclerosis knot layer at its working surface, causes snow cave shovel not work on, and need to manually remove sclerosis knot layer, then work on, waste time and energy, and inefficiency; In order to eliminate the sclerosis knot layer on snow cave shovel surface, occurred resistance wire type electrical heating snow cave shovel, but this Electric heating efficiency of heating surface is low, heat radiation is large, and heat waste is large, and cost is high, and result of use is bad.
Summary of the invention
In order thoroughly to remove the sclerosis knot layer on snow cave shovel surface, improve the efficiency of heating surface, increase work efficiency, the present invention proposes the snow cave shovel device with heating function.
The technical solution adopted in the present invention is: with the snow cave shovel device of heating function, it is characterized in that: the operate portions back side at snow cave shovel is connected with ceramic wafer, the back side of ceramic wafer is provided with electromagnetic coil, and electromagnetic coil encapsulates by shield shell, and electromagnetic coil is drawn wiring terminal to shield shell;
Alternating current generator and power takeoff are in transmission connection, and power takeoff is in transmission connection and is in transmission connection by gearbox power taking window and gearbox;
Electromagnetic coil is electrically connected to high-frequency ac electrical switching device by wiring terminal, and high-frequency ac electrical switching device is electrically connected to DC rectifier again, and DC rectifier is connected with the electric lead-out terminal of alternating current generator.
The invention has the beneficial effects as follows: the present invention utilizes alternating current generator to produce electric weight, the high-frequency alternating magnetic field producing by electromagnetic coil acts on the operate portions of snow cave shovel, by the inner eddy current producing of snow cave shovel, realize heating, there is no heat radiation, the efficiency of heating surface is high, is 1.5-2 times of existing electrical heating efficiency, can remove fast sclerosis knot layer, cost is low, and operating efficiency is high.
Accompanying drawing explanation

Alternating current generator and power takeoff are in transmission connection, and power takeoff is in transmission connection and is in transmission connection by gearbox power taking window and gearbox;
Electromagnetic coil is electrically connected to high-frequency ac electrical switching device by wiring terminal, and high-frequency ac electrical switching device is electrically connected to DC rectifier again, and DC rectifier is connected with the electric lead-out terminal of alternating current generator.
As shown in Figure 1, electromagnetic coil 3 is one.As required, also can, electromagnetic coil is resolved into a plurality of coil units, then draw wiring terminal.
Described electromagnetic coil 3 is helical form air core coils, is to adopt hollow conductor (copper pipe), turns to helical form.
Operating principle of the present invention: the alternating voltage that alternating current generator produces is converted to direct current through DC rectifier, direct current is converted to high-frequency alternating current by high-frequency ac electrical switching device, high-frequency alternating current is loaded on electromagnetic coil and produces high-frequency alternating magnetic field, the magnetic line of force of high-frequency alternating magnetic field acts on the operate portions of snow cave shovel, the eddy current that the inside of snow cave shovel is larger because electromagnetic induction has, thereby produce the operate portions that heat acts on snow cave shovel, thoroughly remove sclerosis knot layer.
