First, the correct choice of operating speed. Under normal circumstances, if the plots are flat, the grains are mature and in the yellow ripe stage, and there are fewer weeds in the field, it is appropriate.
When you increase the speed of the harvester. When grain is in late milk or early yellow ripening, its humidity is relatively high. When harvesting, the speed of advancement should be chosen to be lower.
In the yellow ripening stage or late yellowing stage, the humidity is small and the ripening is uniform, and the forward speed can be appropriately selected to be higher. After the rain or morning and evening dew, cereal straw
Humidity is high, and the speed of advancement should be lower when harvesting. Before and after noon on sunny days, the grain stalks are dried and the forward speed is selected to be faster. For high density
Plants with high plant height and good grain yield should be selected slowly at the time of harvesting, and the speed of grain with low density and short grain should 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. Observe use
After a certain period of time, the state of the technology is indeed stable and reliable, and the grain is mature and dry. The speed of advancement can be faster in order to fully realize the efficiency of machine operations.
Second, the width of the harvest should be appropriate. When the harvester is in perfect condition, full load operation is performed as much as possible. The cutting width is controlled at the width of the header.
The 90% is good, but the amount of feed can not exceed the specified permit value, and there can be no missing cut during operation.
Third, the correct grasp of the height of stay. In the case of ensuring normal harvesting, the cutworm should be as low as possible, but the minimum must not be less than 6cm, otherwise it will cause cutting knife
Eat mud, this will accelerate the blade wear and damage. The height of stubble is generally not more than 15 cm.
Fourth, the correct choice of walking method. There are three kinds of walking methods for harvester operations: 1. Clockwise centripetal rotation; 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. Keep a straight line when working. The harvester should keep a straight line when working, allowing slight correction of direction. Must stop harvesting when turning
Reversing turn or turn around at right angles. Do not turn around and turn around. Otherwise, the harvester will overwhelm the uncut wheat and cause the missing cut.
loss.
6. Use the harvester rationally. Grain harvesting is strictly prohibited during the milk ripening period, when there is no pulp breakage;
Cut; just under the rain, straw moisture, it should not be forced to harvest with machinery. When the operator is working on a specific job, he must be able to use the machine according to the actual situation.
Cut as far as possible to meet user requirements, for individual special circumstances can not be harvested, do not use mechanical harvesting, as far as possible to explain the work to the user, so as not to produce
Negative effects.
