Use Maintenance

 a: For every 40 hours of work, the drum and fan bearing should be checked and a proper amount of grease should be added.

 b: At the end of each use, the thresher should run for 5 minutes without feeding to exclude the remaining material in the machine.

 c: At the end of the operation, the condition of the machine and parts should be checked and the maintenance is carried out.

 d: Every 8-10 hours of work, check the bolts of bearing seats, drum bolts and other important fasteners in time, to ensure the fasteners is firm and reliable.

 e: After every season's operation, check the status of each component, clean up the debris in the machine, clean the bearing parts with gasoline and add grease, paint damaged area should be painted, and the machine is stored in the warehouse.

When replacing the drum parts or nail teeth, the drum must be adjusted for static balance. When replacing the fan impeller, the impeller must be corrected with the static balance.

 

Solution

Failure phenomenon

Analysis of causes

Trouble shooting

 

No straw at the straw outlet

1. The turning of the drum is incorrect.

2. The installation of the guide plate of the cover is reversed

3. The speed of threshing drum can not reach the required speed.

1. Check and correct.

2. Check and correct.

3.Check whether the tightness of the v-belt is suitable or to increase the accelerator of the diesel engine

4. Check whether the motor has reached the rated speed

Threshing is not clean

1. The speed of threshing drum can not meet the requirement

2. Serious wear and tear of nail teeth

1. Make the drum reach the rated speed

2. Replacement of nail teeth

Great loss

1. The amount of feeding is large and uneven.

2. Low crop yield and not full grain

1.Reduce feeding amount and uniform feed

2. Replacement of crops
