Maintenance and maintenance of combine harvester during storage

With the increase of the working time of the combine harvester, parts of the machine will be worn out and aged and need to be replaced or repaired in time. In order to extend the service life of the harvester, reduce the occurrence of faults, maintain a good state of technology, and obtain good economic benefits, the harvester must be maintained and maintained at the end of each harvest season to ensure that it will be harvested during the next season. Work efficiency and economic efficiency.

Cleaning is an important measure to extend the service life of the combine harvester. The operating environment of the combine harvester is rather harsh. If the working time is long, the crop straw, weeds, mud, etc. can easily stick around the working parts such as the transmission wheels and shafts, and it is also easy to hang around the shaker and screening box. , fans, and threshing filters, and other important components. Therefore, at the end of normal operations, it needs to be cleaned frequently. If it is not cleaned in time, the weeds will become more and more entangled, and the mud will become thicker and thicker, which will easily cause rust damage to the parts of the harvester. Therefore, the harvester must perform a comprehensive cleaning work before the end of the harvest season every year, to remove dirt, weeds and other components on the components.

After the combine harvester operates for a long time, the belts, chains, sprockets, pulleys, tensioners, rolling wheels, etc. will wear, deform, roll bearings, bushings, etc. due to wear resulting in excessive clearance and loosening. Therefore, the radial and axial clearances of the pulleys and sprocket must be inspected and adjusted after the end of the harvest season; if the radial and axial clearances are too large, or the gear teeth wear out severely, they should be replaced in time. Grease must be applied to parts such as rollers and bearings, and antirust oil should be applied to parts such as chains, sprockets, and cutters.

As a power source of the harvester, the diesel engine has good working performance and directly affects the work efficiency and economic efficiency of the combine harvester. Therefore, the diesel engine should be maintained and maintained in time, dust, dirt, etc. on the intake and exhaust pipes of the diesel engine and its accessories must be removed. The diesel engine should be drained of oil from the bottom shell, and the bottom shell and oil collector should be cleaned, and then added. Oil, let the diesel engine idling at low speed for a few minutes, then turn off the flame, turn the flywheel, so that the piston is in the compression top dead center position to prevent dust, moisture from entering the cylinder. Cool water should be drained after parking to prevent freezing and cracking.

Check whether the connection of the electrical circuit is firm, and pay special attention to the firmness of the battery power cable and the ground wire connector to keep the outside of the battery clean. Remove oxides from poles, fittings, and tie bars. After clearing, apply grease to the poles and connecting rods and check the battery electrolyte. After the harvester stocks, the battery is not used for a long period of time. In order to better extend the service life of the battery, the battery is charged according to the normal charging method, and the battery is supplemented once a month during the storage period.

The driving system is a combine harvester skeleton system and should be carefully checked. Combine harvester as far as possible to park the machine indoors, to avoid direct sunlight and wind and rain. There must be no oil and corrosive chemicals on the floor of the room, and it is best to put planks under the track to prevent the crawler belt from aging and extend the service life of the harvester.
