In above-mentioned agricultural machinery and implement of the present utility model, further make the equal turn numbers that is positioned at the sub-winding coil at stator main winding both ends in the structure of single-phase motor of said this voltage adjustable, can help guaranteeing the balance of motor force.In addition, make the number of turn of each the sub-winding coil between the sub-winding coil in both ends be less than the sub-winding coil in both ends, also will be more convenient for operating voltage is done adaptive adjusting.
In the above-mentioned said electric motor structure, number being set though multiple choices can be arranged to the said tap structure that is used to distribute main winding, but make the main winding in the said main winding unit adopt tap structure distribution to become 3 sub-winding coils and make one of them tap structure be adopted as the simplest version that the said selector switch through having two selections or movable end connects, generally just can adapt to and satisfy actual use needs in most cases by 2 band connecting terminals.
In the above-mentioned agricultural machinery and implement of the utility model, said power supply selector switch can have multiple choices according to different use needs, as currently reported and/or the multi-form electronic type selector switch that uses, step positioning type machinery selector switch etc.Wherein, simple in structure to adopt, reliable operation, and be particularly suitable for manual operation, the convenient, flexible step positioning type machinery selector switch of operation and maintenance is preferred.
In the above-mentioned agricultural machinery and implement that are applicable to wide-voltage range of the utility model, though said single-phase motor and through the work structuring unit that gear train unit drives essential require to concentrate be provided with, can adopt dispersity to be arranged at the different parts place according to actual operating position and needs, correspondent voltage table and power supply selector switch etc. also can be arranged on required suitable position place, but to adopt the concentrated form that is arranged on the frame is good, said this voltmeter is corresponding with power supply selector switch etc. to be arranged on the guidance panel of frame, operation when being more convenient for using, also convenient moving carried and maintenance.
In the agricultural machinery and implement of the above-mentioned form of the utility model; for further guaranteeing normal the use; the accident and the damage that may cause when avoiding supply power voltage to change suddenly; in said motor line and/or in the peripheral circuit of motor; for example after said power supply selector switch, in the circuit, can also be correspondingly provided with the overvoltage/overcurrent protective devices such as fuse of appropriate format.
Because the driving arrangement in the above-mentioned agricultural machinery and implement of the utility model has adopted the single-phase motor structure of voltage adjustable, therefore can be according to the actual conditions of supply power voltage, connect by carrying out property of the tap selectivity of this power supply selector switch the motor stator main winding, reach the coil turn of regulating and changing real work in the stator main winding, thereby realize easily motor and actual power voltage are complementary, guaranteed the operate as normal and the use of motor.Difference setting by to tap structure/quantity in the stator main winding can be implemented in the wideer voltage range, and/or regulates in meticulousr mode, and is more stable, reliable with the work that guarantees motor.Actual power situation according to power supply network, for areal, the voltage condition of its improper power supply generally can frequent variations and relatively stable (general about about 30 volts), so above-mentioned agricultural machinery and implement of the utility model, can adapt to and satisfy the needs that under various improper electric power thus supplied, still can guarantee its operate as normal fully, solve the practical problem that extensively exists in the use of present rural area and agricultural machinery and implement from far-off regions, and greatly reduced cost.
Below, foregoing of the present utility model is described in further detail again by embodiment by the accompanying drawing illustrated embodiment.But this should be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following example.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the present utility model.
