How to buy a rake
1. Check whether the safety device of the rake is complete and effective. All rotary parts of the rake must be equipped with guards; the distance from the feed axis to the tool axis must meet the following requirements: productivity is less than 0.4
The ton/hour must not be less than 3 times the width of the feed inlet; the productivity greater than 0.4 ton/hour must not be less than 450 millimeters, and the clutch device must be provided; the automatic feed device and overload protection device must be installed when the productivity exceeds 2.5 tons/hour. The bolts used for the bearing seats and the knife seats must be high-strength bolts, and anti-loosening devices (such as spring washers, etc.) should be added. Do not meet the above requirements of the rake, the use of personal safety accidents, do not buy.
2, check the appearance of quality and assembly quality. The welding part of the rake should be uniform and smooth in the welding seam, and there should be no burn-through or miss-welding. The turf cutter shaft should be flexible and free from seizure when the clutch is disengaged; the protective cover of each part should have a certain strength.
The use of rakes
1. The rake should be placed or fixed on a solid, level foundation. It must be stable during operation and cannot have large vibrations.
2. Before starting the machine, it is necessary to conduct a comprehensive inspection of the various parts of the machine. Move the rake cutter shaft by hand to see if the rotation is flexible, if there is any crack in the cutter plate, and if the fasteners are loose, find out that the hidden troubles should be promptly eliminated.
3, before the operation, let the rake idling for a while, observe whether the operation is stable, whether there is abnormal noise, confirm the normal operation and then put into operation.
4, feed should be uniform, if the feed shaft too much lead to reduce the speed of the knife shaft, it should stop cleaning.
5, before processing feed, should remove the impurities in the material, prevent iron, stones and other hard materials feeding.
6. If grass jamming occurs during operation, immediately disengage the clutch and stop it to remove the fault. Do not open the protective cover while the machine is running.
7. Stop the feeding before the end of the job. Wait until all the materials in the standby device are discharged before separating the clutch and cutting off the power. Clean up the debris in the machine.
maintenance
1. Always check the fasteners for looseness and tighten them.
2. Strengthen the maintenance of bearing seats, couplings, and transmission boxes, and regularly add or replace lubricating oil and grease.
3. For cutting rakes with adjustable cutting gaps, the cutting clearance should be properly adjusted according to the thickness of the crop stalks to ensure the normal operation of the rake.
4. When the blunt edge of the blade is found, apply the oilstone to sharpen the blade.
5. After the class is finished, the dust and dirt on the machine should be promptly removed. After the end of each season, the debris in the machine should be removed. Anti-rust oil should be applied to the working parts and placed in a ventilated and dry place indoors.
