Common Faults and Troubleshooting Methods of rice threshing and shelling machine:

Fault phenomenon	Failure cause	Troubleshooting method
The motor can not start or start difficult	The fuse is broken, the wire diameter is too small, the voltage is too low, the capacitor is damaged	Connect the fuse, change the larger diameter conductor, restore the voltage and then start, replace the new capacitor
Motor temperature is too high	Motor winding short circuit, motor bearing damage, long-term overload operation	Overhaul, change motor bearing, work or pause according to rated load
Spindle work weakness	Belt slipping, spindle flat key off	Properly tighten the belt, change the new spindle flat key
Strong vibration of fuselage	The gear disc is driven, the main shaft is bent, the bearing is damaged, and the stop screw is loose	The gear disc is driven, the main shaft is bent, the bearing is damaged, and the stop screw is loose
The machine is jammed and there is metal knocking in the mill room	There are metal, stone and other hard objects into the body, parts of the body damage or fall off, the gap between the gear disc is too small, the gap between the roller is too small	Stop check out hard, stop check repair replacement parts, appropriate gear disc clearance, clearance adjustment of rice ro
Spindle can not rotate	The belt is too tight, the machining material is not exhausted, the main shaft bearing is damaged	Loosen the spindle belt properly, remove the material in the grinding room, and change the spindle bearing
Cannot discharge material	Motor steering error, foreign matter blockage at feed port	Remove the foreign body by changing the wiring head
The motor can not start	There is a problem in the power supply, two rubber rollers are jammed, and the motor is burnt out	Check the power line, loosen the rubber roller, send the maintenance department Shelling net
Shelling is not complete	Two rubber roller gap is too large, roller rubber wear is too large, rubber roller wear uneven	Adjust clearance, replace, repair or replace before grinding
Grain shells can't be cleaned	The fan belt is loose and the air outlet is blocked	Replacement, cleaning or slag discharge
Too many broken grains	Rubber cot clearance is too small	Adjust handwheel clearance adjustment

If you need grain processing machines sucha as grain dryer machine, mung bean peeling machine,pumpkin seed shelling machine,soybean peeling machine,peanut shelling and peeling machine etc. , just fell free to conatc me.
