The header is an important part of the corn harvester equipment. The maintenance and overhaul of the header should be protected. If the equipment is not in use, how should the head be overhauled? Let me summarize it today.
Overhaul of the header section of the Factory supply and widely used Agricultural walking tractor driven mini corn harvester:
The header part mainly includes a reel, a cutter, a pusher, a tilting conveyor and the like.
1. Repair of the reel
Before inspection, it should be checked whether each spring shaft is bent and deformed, whether the spring teeth are lost or damaged, and if necessary, it should be adjusted and replenished. The contents of the reel maintenance include: 1 Check the height of the reel. Place the reel wheel at the lowest position, the spring teeth should not touch the cutter and the header auger; 2 check the front and rear positions of the reel. There should be a proper gap between the reel and the cutting auger rotating blade. Under the premise of not touching, the axis should be located directly above the cutter or slightly forward. 3 Adjust the reel speed. When harvesting corn, the circumferential speed of the reel should generally not exceed 3 m / s, in order not to repeat the attack on the ear of corn and not to push the corn stalk forward. 4 Adjust the angle of the reel's teeth. The erect crop teeth should be perpendicular to the ground, and the crops can be adjusted backwards by 10o~30o. Receiving a dense crop can tilt the spring teeth forward. Under normal circumstances, it is advisable to tilt the elastic teeth about 10o backward. Work on the eccentric web before work. The three rollers are lubricated and lubricated to make them flexible; otherwise, the reel will be unstable and the plate will wear seriously.
2. Overhaul of agricultural hand-held tractor driven mini corn harvester cutter
Mainly check whether the blade is intact, whether the blade is fixed firmly, whether the moving blade and the center line of the fixed blade are coincident, and whether the gap between the blade and the blade is correct. The cutter blade is divided into two types: a light edge and a serrated blade. The movable blade is a serrated blade, and the fixed blade is a light blade. The main contents of the cutter inspection include: 1 Check whether the blade is blunt or damaged. In order to reduce the cutting resistance, the blunt or damaged blade should be replaced in time. When the blade edge wears to 0.15 mm and the tooth height is less than 0.5 mm, when there are more than 3 consecutive teeth missing, the new blade should be replaced. The sawtooth type moving blade is generally only replaced and not repaired. The blade of the light blade is blunt and the blade can be ground by more than 0.3 mm. The blade width should be less than the width of the blade. When the blade is riveted, the rivet head must be correct and stable. The top surface of the fixed blade should always be on the same plane. 2 Check if the shank is bent and broken. For a curved arbor, you can strike it with a hammer until the arbor is straight, the broken arbor can be welded and repaired, and the welded joint after welding the shank should be flat. 3 Check the clearance between the fixed blade and the moving blade. This gap should be within 0.3-1 mm, the front end is no more than 0.5 mm, and the back end is no more than 1.5 mm. This clearance can be adjusted by correcting the position of the blade.
