Working principle of corn harvester: mainly consists of cutting rod device, conveying device, hydraulic elevator and so on. When working, the machine moves along the direction of the corn ridge, the cutter cuts off the corn straw, and the straw is output in the right direction of the upper, middle and lower three conveyor chains, and is placed naturally to complete the harvest. The separation of power is that the driver operates the hydraulic lifting system of the tractor, and after the main engine is lifted up to the position where it stays, the two B-shaped triangle belts will stop rotating, cut off the power input of the diesel engine, achieve the separation of power, the cutter and the conveyor belt will stop rotating. Otherwise, it will be in a working rotation state.
Installation debugging edit broadcast: 1. Check whether the front bumper of the tractor is level. If it is not level, it should be corrected before installing the lifting frame. 2, the lifting frame is installed on the bumper of the tractor, and then the press plate is tightened by screws, and then the end of the two diagonal flat iron is connected to the lifting frame, and the other end is connected and fixed with the connecting seat welded on the tractor girder. Ensure the machine has good stability. 3. The connection between the host and the lift is through the four U-shaped cards on the host and the two front supports of the lower part of the lifting frame. The two U-shaped cards on the lifting frame pass through the four cylindrical pins, and the two active lifting plates connect the host and the lifting frame together. 4, the diesel engine and the reducer box of the harvester are connected with two B-type triangle belts, after installation, do not press the tightening wheel too tight, in the case of normal harvesting, as long as there is no triangle belt slip phenomenon. 5, after the assembly, it should be idled for 5 minutes, and then high-speed operation for 6 minutes, after checking the components are not abnormal, you can work in the field. 6, the adjustment of the stubble height is achieved by the adjustment screw of the lifting frame. Before harvesting, first adjust the cutter to contact the soil and ground, and then lock the screw for a test cut to see whether the stubble situation is suitable, if not, then adjust to meet the requirements can start harvesting. 7, because the harvester is the right conveyor, in the field harvest, the harvesting method to improve efficiency is to harvest around the plot. 8, the cutting tool is made of alloy steel, after a period of use, especially after the use of sand land, the cutting edge part of the wear becomes dull, at this time to use a portable grinder grinding out the cutting edge, in order to facilitate the harvest to save power, but in the grinding edge to prevent overheating, dripping cooling, so as not to reduce the durability of the cutting edge part. Corn harvester is a farming machine used to complete the harvest of corn stalks according to agronomic requirements when corn is mature or close to maturity.
Pre-assignment editing broadcast engine: The engine is the core component to ensure the normal operation of the machine, so it is necessary to check the oil supply time before operation, and focus on the valve clearance and other parts, and adjust the problem in time. Cutter assembly This is an important working part of the combine, focus on the maintenance of the following parts of the cutting edge thickness of the fixed cutter head wear to more than 15, the tooth height of the moving blade is insufficient or continuous lack of teeth more than one, should be replaced with a new piece loose to riveting firmly. If the front end of the fixed blade clearance is greater than, the back end is greater than, the clearance of the blade press should be adjusted to be less than. Check that all guards are on the same plane. thresher It is mainly to check and adjust the threshing gap and the rotating speed of the drum, and to adjust the stripping rate and productivity under the premise that the grain does not appear too high crushing rate. Adjust the threshing gap should pay attention to the left and right sides of the same, rotate the drum to check the grain rod one by one, check the tooth one by one, adjust the drum speed according to the requirements to match the threshing gap, the principle is to use the lowest speed and the maximum threshing gap under the premise of maintaining the cleaning rate. Clean the mechanical radiator and filter Corn combine harvester in the operation of the location of the farm, the relative field environment is also relatively harsh, in the operation process, the harvester will raise grass crumbs and dust. After a long period of operation, the radiator is easily affected by these external factors, causing the blockage of the radiator, thus affecting the heat dissipation function of the machine. At the same time, for the filter of corn combine harvester, under the condition of dust and grass clippings for a long time, it will affect its use effect, appear black smoke, power decline, etc., and lead to mechanical failure in serious cases. Therefore, it is necessary to check and clean the mechanical radiator and filter in time. Carefully inspect each welding part for damage It is necessary to strictly check the welding parts of the corn combine harvester to ensure that there is no wear phenomenon of the parts, and to eliminate potential cracks, deformation, damage and other hidden dangers that may exist in the welding parts.
