Grasping the correct method of operation of the wheat combine harvester can achieve a multiplier effect. It is both safe and economical. Here are a few job "skills":
First, the correct choice of operating speed Under normal circumstances, if the plot is flat, uniform grain maturity and in the yellow maturation period, when there are fewer weeds, can be appropriate to improve the speed of the harvester. When grain is in the late milking stage or the early yellowing stage, the humidity is relatively high. When harvesting, the forward speed should be selected lower. When the grain is in the yellow ripening stage or the late yellowing stage, the humidity is small and the ripening is uniform. The forward speed can be appropriately selected to be higher. After the rain or morning and evening dew, the moisture content of the corn stalks is high, and the speed of advancement at the time of harvesting should be lower. Before and after noon on sunny days, the grain stalks are dried and the forward speed is selected to be faster. For grains with high density, high plant height, and good yield, the forward speed should be chosen to be slower when harvesting, and the speed of grain with low density and short grain can be faster. When the harvester is just started to work, the technical status of each component is in the use observation stage, the work load is smaller, and the forward speed is slower. After observing the use for a period of time, the technical state is indeed stable and reliable, and the grain is mature and dry, and the advancement speed can be faster, so that the operating efficiency of the implement can be fully utilized.
Second, the size of harvesting width should be appropriate in the case that the harvester is in perfect condition, perform full-load operations as much as possible, and the cut width is preferably controlled at 90% of the width of the header, but the feed amount cannot exceed the specified allowable value. There should be no missing cut during operation.
Third, the correct grasp of stubble height in the case of ensuring normal harvesting, cutting as low as possible, but the minimum must not be less than 6 cm, otherwise it will cause the knife to eat mud, which will accelerate the blade wear and damage. The height of stubble is generally not more than 15 cm.
Fourth, the work walking method to choose the correct harvester operation when there are three kinds of walking methods: 1, clockwise centripetal rotation method; 2, counterclockwise centripetal rotation method; 3, spindle-shaped harvest method. In the specific operation, the operator should be flexibly selected according to the actual situation of the site. The general principle is: First, it is convenient and quick to discharge food. Second, we must minimize the number of locomotives.
5. During operation, the straight-line driving of the harvester should be kept in a straight line to allow minor corrections. When turning, it is necessary to stop harvesting. Use the reverse method of turning or turn the basket to make a right-angle turn. Do not turn around while cutting. Otherwise, the harvester will overwhelm the uncut wheat and cause loss of missing cuts.
VI. Reasonable use of harvester grain During harvesting period, it is forbidden to harvest when there is no broken pulp; it is not appropriate to use mechanical harvesting for cereals that fall too heavily; just under the rain, the humidity of the straw is high and it is not appropriate to forcibly harvest by mechanical means. When operating the operator in a specific operation, according to the actual situation, it is possible to use mechanical harvesting to meet the requirements of the user as far as possible. For individual cases that cannot be harvested, do not use mechanical harvesting. Do as much as possible to explain the work to the user, so as to avoid negative effects.
