After one year's work of the harvester, due to friction, vibration and load changes caused by the operation, inevitably there will be loose connections, parts wear, and changes in the clearance, resulting in deterioration of the machine's technical state, increasing failures, and work efficiency. If the cost of equipment is reduced, the cost will increase. In order to make the equipment more energy-efficient when it is busy in the following year, it should be maintained during long-term storage in the slack season, and pay attention to the following matters:
First, store
Remove all dirt, dust, oil, debris, etc. on the whole machine. The organic library is best stored in the hangar. There is no hangar to find a safe, flat, dry, ventilated, sunny place, and use "three "Color" cloth cover will cover the whole machine to avoid sun exposure.
Second, the chassis
1. Put the chassis on the same level, do not allow the walking track to be pressed for a long time, and the height is not suitable for the crawler. When the roof is raised, the four supporting points must be on the same level to avoid uneven long-term pressure. Deformation of the rack; walking track to relax, remove and wash, dry, coated with talcum powder, crawler without the hangar should be stored indoors, to avoid overwinter deformation aging, walking roller, drive wheel bearing parts, check the oil seal water Whether the seal is good or not is replaced with a bad one, and new butter must be added.
2, check the gearbox, gear oil is up to the standard, less than enough.
3, check the clutch is normal, "minutes" and "away" is obvious, abnormal adjustments, replacement clutch friction plates, springs and so on.
4. Check whether the transmission, clutch, steering mechanism and device are normal, if the steering knuckle is loose, must be tight and reliable, and then apply lithium-based butter on the surface.
Third, the header
1. Place the header on the same horizontal surface and use a wooden material to pad the header to prevent the header from directly contacting the ground. The lifting cylinder of the header is in a completely inoperative state. The reel is fully fed into the combine. Hydraulic lift should also be placed in the lowest position.
2. Check if there is any peeling paint at the header, if any, should be cleaned, repainted or painted with rust-proof oil, whether the feeding table is full or not, whether the bearing at both ends is worn or not; The inspection dials are inspected for signs of fission and wear. The chain, supply chain, feed chain, right conveyor chain, left stem conveyor chain, etc. need to be unstressed and brushed with waste engine oil. The chain drive wheels are also painted with waste engine oil; the bearings of the chain tensioners are inspected. It is better to loosen the tension screw of the claw belt under the header abutment chain to the belt.
3. Whether the cutting knife is damaged or loose, otherwise, replace it. At the same time, tighten each knife and check the gap between the fixed knife and the movable knife. Then, apply lithium-based butter on the surfaces of the stationary knife and the moving knife.
4, check all the transmission parts (including threshing device parts): belt tensioner to relax, there is no hangar belt should be removed, and then check whether there is a need to replace, if not replaced, coated with talcum powder on each belt, Store in room (including threshing roller belt, threshing filter belt, fan belt, stir belt, shaker belt, grass belt, grass cutting belt); remove the chain completely, wash it with metal cleaning solution, then use The waste oil is soaked for two days, then coated with lithium-based butter, wrapped and stored, and then installed again.
5, whether the full feed trough is modified, conveyor belt or chain for the corresponding inspection and maintenance.
Fourth, threshing device
1. Turn the threshing chamber open: Clean up the weeds and prevent the rotting from corrupting the machine.
2. Check whether the threshing drum is worn and deformed, whether the threshing gear rod is damaged or not, whether the bearing at both ends of the threshing drum is worn, and re-injected butter.
3. Check whether the gravure chamber concave screen and shaker are normal.
4. Wrap horizontally and vertically, and open the sweeping mouth of the shaker. Then, free up the threshing section and clean the unreleased rice to prevent rats from biting the wire.
5, half-feeding will feed deep and shallow transport chain, threshing transport chain, grass transport chain to relax in the unforced state, check the chain drive wheel is worn, the chain will be painted on the waste oil.
Fifth, the electrical part
Mainly to remove the battery positive and negative connectors, rinse with hot water rinse oxide and the surface clean, if there is enough electricity, according to the provisions plus good electrolyte stored in the room; if there is no electricity, use distilled water to repeatedly wash the inside of the battery, until The distilled water poured out of the battery is not sour, and the electrolyte is added and fully charged. The liquid cap is screwed tight and stored indoors.
Sixth, engine
1. Imported engines are generally not a big problem, as long as the debris outside the water tank is cleaned to ensure the ventilation of the water tank.
2, domestic engines: to recheck cylinder head bolt tightness; fuel supply part is mainly to check the tightness of the diesel tank, tubing, replace the oil filter, to ensure smooth flow of oil, the oil pressure is normal, long-term storage diesel engine start must drain air. Diesel oil will not hydrate in the tubing for a long period of time. Cooling water should be drained to prevent the water tank from rusting. The temperature of the tank will be frozen and the water tank will be frozen. The lubrication system will check the tightness of the oil tank and tubing. Replace the oil filter and check the scale of the oil with an oil gauge. The air filter should be cleaned. The air filter should be sealed with a waterproof cloth. In order to prevent rain and other debris from entering.
With modern machinery processing industry development, for the continuous improvement of quality and accuracy of cutting, to improve the production efficiency, reduce production cost, high intelligent and automatic cutting function requirement also is increasing. The development of CNC Cutting machine must adapt to the request of the development of modern mechanical processing industry. Cutting machine flame cutting machine, plasma cutting machine, laser cutting machine [1], water cut, etc. Laser cutting machine for the efficiency of the fastest, the highest precision cutting, cutting thickness is generally small. Plasma cutting machine cutting speed quickly, cutting surface has a certain slope. Flame cutting machine for greater carbon steel in the thickness of the material..
classification Cutting machine pictures Cutting machine pictures Cutting machine to distinguish from cutting material, divided into metal cutting machine and nonmetallic material cutting machine. Metal cutting machine flame cutting machine, plasma cutting machine, laser cutting machine, water knife cutting machine, etc.; Nonmetallic material cutting machine cutting machine mainly tools. Cutting machine to distinguish from the control way, divided into CNC cutting machine and manual cutting machine. CNC cutting machine Is to use digital process driven machine movement, as the machine tool movement, random matching of cutting tools for cutting objects. The mechanical and electrical integration of cutter is called the CNC cutting machine. Laser cutting machine for the efficiency of the fastest, the highest precision cutting, cutting thickness is generally small. Plasma cutting machine cutting speed quickly, cutting surface has a certain slope. Flame cutting machine for greater carbon steel in the thickness of the material. Range of application Cutting machine used with metal and nonmetal industries, in general, nonmetal industry points more meticulous, as there is
Cutting machine, cut off machine, off machine
