Combine harvester operating points and precautions

First, the operating points of the combine harvester

(A) The correct choice of operating speed Under normal circumstances, if the plot is flat, the grain is mature and in the yellow maturation period, when there are fewer weeds in the field, the advance speed of the harvester can be appropriately improved. 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.

(b) The size of the harvesting width should be appropriate. When the harvester is in good condition, the full-load operation should be carried out as much as possible, and the cutting width should be controlled at 90% of the width of the header, but the amount of feed should not exceed the permitted value. There should be no missing cut during operation.

(C) the correct grasp of the height of stubble in the case of ensuring normal harvest, 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.

(four) the correct choice of walking method of operation There are three kinds of walking methods when the harvester is operating: 1, clockwise centripetal rotation method; 2, counterclockwise centripetal rotation method; 3, shuttle-shaped harvesting 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 shall be kept in a straight line, allowing slight corrective directions. 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.

(6) 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 are too severely fallen; 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.

II. Driving Precautions During Operation of Combine Harvester

The combination of the Southern Harvest and the Southern Warfare has become a major landscape in the summer and autumn harvest season. For the sake of the security of the drivers and the happiness of the family, we would like to awaken our friends who work in cross-region:

(1) The operator must carry the combine harvester number plate, driving permit and driver's license issued by the agricultural machinery supervision department before driving the combine harvester. It is strictly forbidden that there is no discrepancy between the driver's license or driver's license and the driver's license.

(b) The cross-district operation certificate of the combine harvester taken with it should be placed in a prominent position. In order to law enforcement officers to check the road and as a basis for exemption from payment.

(3) The interval between multiple combine harvesters or other vehicles must be separated from each other. Do not follow too tightly to avoid tailgating accidents with the preceding vehicles.

(4) The medium speed running and the courtesy shall be the first priority in the course of operation. It is forbidden to drive at high speed, brake sharply, and make a sharp turn.

(5) In case of inspection by law enforcement officials, they must take the initiative to slow down, stop by the side of the road, consciously accept the inspection, and must not be forced to open the hero car in front of the inspectors.

(6) In addition to the two operators who take turns driving on the combine harvester, the rest of the team is best to take a train or a car to the cutting location. You must not sit on an inclined conveyor or sleep on the unloader's table and the cabin lid to save money.

(7) Operators who go out by themselves or work in groups with the agricultural machinery department should maintain communication and communication with each other. When waiting for the missing vehicles, they should choose to drive the road with a small number of vehicles and stop by the side of the road, and use triangular wood or bricks to cover the tires. . Waiting for the night to open the width of the small lamp to show the position. Never stop the machine on the bridge or under the high voltage wires.

(8) Always stop and check the tire pressure, the tightening conditions of the bolts, and touch the hub with hot hands.

(9) In summer, the temperature is high. The driver must pay attention to rest and prohibit fatigue.

Chunmee is one of the treasures of Green Tea. Also is the world's tea treasures, The shape is tightly tied, well-balanced, grey-green frost, oily and fragrant.
