Abstract
The utility model provides a protector of an ash delivery scraper blade chain conveyor, which comprises a plurality of current overload protectors connected with a driving motor of the ash delivery scraper blade chain conveyor, wherein the current overload protectors are connected in parallel and are connected in series with the driving motor and an input power source of the driving motor; a switching circuit is arranged for each current overload protector; and the current overload protectors have different overload protection current values. With adoption of the scheme of the utility model, the current overload protectors with different working current values are connected in parallel, and a switching circuit is arranged for each current overload protector. In this way, in actual use, one of the current overload protectors is set to work as required, so as to determine a proper working current of the driving motor and prevent a chain from being destroyed when the working current of the driving motor is too high.
Description
Technical field
The utility model relates to field of mechanical technique, refers to especially a kind of defeated grey flight chain motor protector.
Background technology
Because existing defeated grey flight chain machine all adopts continuous operation mode, each component wear of chain is serious, and the chain derailing often can occur, and causes chain to be transmitted machinery and seriously breaks distortion.Existing defeated grey flight chain machine structure is that the sealing trench is installed, and chain is pulled off rear maintenance difficulty and takes time and effort, and has a strong impact on the normal operation of system.
Through experiment, find, existing defeated grey flight chain machine, the drive motor power configuration is bigger than normal, causes chain seriously to be broken distortion.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of defeated grey flight chain motor protector that can control the drive motor work of defeated grey flight chain machine.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of defeated grey flight chain motor protector, a plurality of current over-load protectors that comprise the drive motor that connects described defeated grey flight chain machine, described a plurality of current over-load protector parallel connection, and connect with the input power of described drive motor and drive motor; Wherein said each current over-load protector all is provided with a switch circuit, and described each current over-load protector has not identical overload protection current value.
As technique scheme preferably, described a plurality of current over-load protectors are connected with alarm indicator.
As technique scheme preferably, described alarm indicator comprises warning indicator lamp and alert loudspeaker.
As technique scheme preferably, described switch circuit is one manually to control travel switch.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, adopted the current over-load protector parallel connection of a plurality of different operating electric currents, and be provided with a switch circuit for each current over-load protector.Can when reality is used, set as required one of them current over-load protector work like this, to determine the working current of suitable drive motor, prevent that the drive motor working current is excessive and cause drawing bad chain.
The accompanying drawing explanation
The structural representation that Fig. 1 is defeated grey flight chain motor protector of the present utility model;
[main element nomenclature]
1: current over-load protector;
2: drive motor;
3: input power;
4: switch circuit;
5: alarm indicator.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1; the defeated grey flight chain motor protector of the utility model embodiment; a plurality of current over-load protectors 1 that comprise the drive motor 2 that connects described defeated grey flight chain machine; described a plurality of current over-load protector 1 parallel connection, and connect with the input power 3 of described drive motor 2 and drive motor 2.Wherein said each current over-load protector 1 all is provided with a switch circuit 4, and described each current over-load protector 1 has not identical overload protection current value.Can when reality is used, set as required one of them current over-load protector work like this, to determine the working current of suitable drive motor, prevent that the drive motor working current is excessive and cause drawing bad chain.
Wherein, described a plurality of current over-load protector 1 is connected with alarm indicator 5.Concrete, both can make the current over-load protector of all parallel connections all be connected to an alarm indicator.This alarm indicator is reported to the police new number detecting after circuit is short-circuited to send.This alarm indicator comprises warning indicator lamp and alert loudspeaker.
Wherein, described switch circuit 4 is a manual travel switch of controlling.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
