Electrically connect with selecting switch after resistor coupled in parallel, described selecting switch is electrically connected with one end of positive switch coil or and reverse winding
One end electrical connection.
In a kind of above-mentioned anti-blocking control system of rotary cultivator, the stroke that described blade assembly falls back is a quarter
Circle.
Compared with prior art, the utility model has the advantage of by the circuit of anti-blocking controlling organization for detect
Motor speed pass through during working condition current of electric to detect, does not meet setting value when detection means detects motor speed
Or the electric current that passes through of electric machine operation state is when exceeding setting value, controlled motor reversion a quarter circle, make blade assembly fall back from
And release blade and be stuck state.There is the stall that can simply, fast and effectively solve the problems, such as blade assembly, side
Case is simple, with low cost.
Description of the drawings
Fig. 1 is the circuit theory diagrams of the anti-blocking control system of this rotary cultivator.
Specific embodiment
The following is specific embodiment of the utility model and combine accompanying drawing, further is made to the technical solution of the utility model
Description, but this utility model is not limited to these embodiments.
In figure, motor 1；Blade assembly 2；Control module 3；Varistor 4；Current detection module 5；Forward-reverse switch module
6；Velocity feedback module 7；Positive switch coil 8；Reverse winding 9；Master switch 10；Selecting switch 11.
As shown in figure 1, the anti-blocking control system of this rotary cultivator, includes motor 1, blade assembly 2 and control module 3, electricity
Machine 1 is used to drive blade assembly 2 to rotate, and control module 3 works for controlled motor 1, between control module 3 and motor 1 respectively
Current detection module 5 and forward-reverse switch module 6 are electrically connected with, forward-reverse switch module 6 is electrically connected with motor 1, electric current inspection
Survey module 5 to electrically connect with control module 3, current detection module 5 is used for electric current of the detection by motor 1, when current detection module 5
When detecting motor 1 and not meeting the electric current that setting value or 1 working condition of motor pass through, 6 controlled motor 1 of forward-reverse switch module is entered
Row switching reversion falls back blade assembly 2 to be stuck state so as to release blade assembly 2, the stroke that blade assembly 2 falls back here
For a quarter circle.
