Scarifying machine|Electric hand milling machine for concrete pavement repair

Product description:

Sarifying machine is a light motor drive ground milling machine to 7.5kw kilowatts Y132M-4 variable speed motor as the driving force, the use of forward cutting the working principle, can quickly cut the ground material! Working principle: Unlike the large-scale milling machine's anti-cutting principle, the small milling machine relies on the positive high-speed rotation of the milling drum, so as to shake the six groups of hard tungsten steel alloy blades on the milling cutter shaft. , The use of alloy blade on the tungsten steel alloy teeth to break and ground the ground material, so as to achieve the effect of surface milling;

Products use:

Concrete scarifier machine Mainly used for highway, urban roads, airports, freight yard and other asphalt concrete surface of the excavation renovation, can also be used to remove the road package, oil waves, textures, rutting and other defects can also be used to excavate pits and ditch Groove, and the cement road surface of the hair and the surface of the wrong level of milling.

 Concrete scarifier machine use and maintenance

1 machine is the main part of the work due to milling cutter, bearings, gaskets, milling drums, the operation process due to a long time with the road friction, the fastest consumption is this part of the regular replacement, inspection in order to better extend the use of the machine life;

2, milling cutter shaft should be checked daily, if the above grinding out of the slot more than 25% of the diameter of the knife, you have to replace. In general, the life of the knife shaft is half the life of the tungsten steel cutter. scarifying machine From the square area, the life of the milling depth of 5mm when about 350-500 square meters. But please pay attention to, there are many factors that will affect the life of the knife shaft, so to check every day;concrete scarifier machine zhongtuo.png

3, for safety reasons, before the maintenance, should first pull the engine spark plug, preferably by the qualified mechanic;

4, each time before running to check the oil level, after use to clean the air filter;

 5, every 4 hours after use, to grease the bearing. concrete scarifier /Hit the grease, while playing side of the rotation drum, so that grease coated in the entire bearing;

6, before each operation with the naked eye to check the machine: all fasteners are tightened? Are there any parts of the obvious wear or cracking? Oil pipeline is intact? Check the bearings, check the cover is covered;

7, before each operation, to check the belt tightness. The new belt should be reoriented after 4 hours of operation, and the belt tension must be maintained in order to transmit the output horsepower of the engine to the cutter drum. scarifier concrete grinder When the tight belt is too tight, the belt will be easily worn and the bearing life will be shortened , If broken, serious wear and tear of the belt should immediately change the new; forget the past to have a new start.      scarifying machine zhongtuo.png                                        

8, in general, milling cutter cracking is very rare, if any, usually shows the following: a: milling cutter on the irregular arrangement; b: a single milling too deep; c: the use of inappropriate milling Knife to remove the different types of road; d: milling the surface strength is too large; to be courage to admit their mistakes, and bear the responsibility.

9, each time you change the milling cutter arrangement, check the cutter shaft and the bearing. If the shaft appears to wear the groove, you need to replace the new, when the axis for the same time for bearings;

10, milling drum if properly maintained, usually can be used for 3 months. When checking the milling cutter or doing maintenance, check whether there is any cracks in the center axis of the milling drum, whether the sleeve hole is oval, whether there is any crack at the weld, and if there is any damage,

11, and finally, when you want to check the milling machine at the bottom of the milling machine, reminded that: the machine must be tilted forward, never backward, or oil will pour into the engine cylinder.
