Abstract
The utility model provides a snow shovel device with a heating function. A ceramic plate is connected to the back of an operating portion of a snow shovel. An electromagnetic coil is disposed on the back of the ceramic plate and is packaged through a shield housing. A connecting terminal led from the electromagnetic coil is led out of the shield housing. An alternating current generator is in transmission connection with a power takeoff. The power takeoff is in transmission connection with a gearbox through a gearbox takeoff window. The electromagnetic coil is electrically connected with a high-frequency alternating current converter through the connecting terminal; the high-frequency alternating current converter is electrically connected with a direct current rectifier; the direct current rectifier is connected with a power output terminal of the alternating current generator. The snow shovel device has the advantages that high-frequency alternating magnetic field is used to act on the snow shovel, heating is achieved through eddy current generated from the inside of the snow shovel, no thermal radiation occurs, heating efficiency is high and is 1.5-2 times of the existing electric heating efficiency, a hardened solid layer can be removed fast, the cost is low, and operating efficiency is high.
Description
Technical field
The utility model relates to the snow cave shovel of snow shoveling machine, especially the snow cave shovel device with 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 utility model proposes the snow cave shovel device with heating function.
The technical scheme that the utility model adopts 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 with high-frequency ac electrical switching device by wiring terminal, and high-frequency ac electrical switching device is electrically connected with DC rectifier again, and DC rectifier is connected with the electric lead-out terminal of alternating current generator.
The beneficial effects of the utility model are: the utility model 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, realize heating by the inner eddy current producing of snow cave shovel, 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.
Brief description of the drawings
Fig. 1 is the structure chart of snow cave shovel in the utility model.
Fig. 2 is schematic diagram of the present utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, further describe the utility model as follows: with the snow cave shovel device of heating function, snow cave shovel 1 is provided with the connection bracket 1a with snow shoveling machine, the operate portions back side at snow cave shovel 1 is connected with ceramic wafer 2, the back side of ceramic wafer is provided with electromagnetic coil 3, electromagnetic coil 3 encapsulates by shield shell 5, and electromagnetic coil 3 is drawn wiring terminal 4 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 with high-frequency ac electrical switching device by wiring terminal, and high-frequency ac electrical switching device is electrically connected with 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 multiple 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.
The utility model operating principle: 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 generation heat acts on the operate portions of snow cave shovel, thoroughly remove sclerosis knot layer.
