Take Dongyang pf455s hand transplanter for example. Describe its use and maintenance methods.
First, the correct use of transplanting operations should be confirmed before the matter: First, the first four rows is a reference to insert a row, should pay special attention to operation. Keep it in a straight line. Second, before the transplanting operation begins, it is necessary to check: whether the shift lever is set to the “transplanting†speed range; whether the hydraulic operating handle is set to “drop†position; whether the plug-in clutch handle is dialed to “connect†position; Insert a marker on one side of the cassette so that the marker extends; the main clutch handle is set to the “connect†position, the throttle handle is slowly swiveled inward, and the plug-in unit is pushed forward.
Second, the post-season maintenance technology points Plug-in machine after planting, long-term storage before the need for detailed mechanical inspection and proper maintenance.
1. The appearance of initial cleaning. The pf455s rice transplanter uses more plastic parts, so the appearance should not be washed with a high pressure water gun. It should be brushed with low-pressure water while the engine is running at medium speed. And pay attention to avoid water flow into the air filter and steel wire to avoid rust stuck. Do not stop immediately after cleaning and continue to operate for 2-3 minutes.
2. Engine maintenance. The machine uses a 169 kW four-stroke gasoline engine with a rebound starter. The replacement of oil should be fully working in the engine. The temperature rises, the engine oil heats up and thins out, and then the new engine oil is injected. The amount of oil is based on the dipstick marking. The sponge in the air cleaner is gently blown with gasoline and blow dried. A few drops of oil are added. Due to the strong volatility of gasoline, long-term storage is easy to form colloidal precipitates in the oil circuit and carburetor, so all gasoline in the oil circuit should be drained. Specific method: Start the engine, turn off the oil switch until the engine stalls. Then light up the gasoline in the fuel tank. In order to prevent the cylinder wall and valves from rusting, 20 milliliters of new oil is poured into the spark plug hole, and then the starter is pulled for 10 turns and stops at the position where there is compression.
3. Adjustment and maintenance of the operating part. Raise the handrail of the transplanter, pull out the leather case on the wire pulling wire under the control panel, and inject the oil mixture (lubrication effect) and the diesel oil (remove rust effect) in a ratio of 1:1. Steering handle free clearance can be adjusted by adjusting the nut. The main clutch and the planting clutch lever start to act in the "cut" position. The hydraulic handle should act on the "up" position. At the yellow sign of the rice transplanter, the rotary motion part is poured or buttered. Side bracket, drive sprocket box should be added 90 # gear oil. In the planting arm, a mixture of oil and butter is injected in a ratio of 1:2. The quantity should not be excessive. The butter needle can be removed and stored after being buttered. In order to extend the life of the pressing spring of the planting arm, the planting fork should be kept at the lowest position (pressing the seedling state). The rice transplanter should be stored in a dusty place with low moisture and cool shade. Due to the large number of fuselage plastic parts, contact with chemicals should be prevented; and the main clutch handle should be “disconnectedâ€, the hydraulic handle should be “downâ€, and the start switch should be “offâ€. Cover tarpaulin. Make sure that the spare parts and tools are stored together with the rice transplanter.
