In the spring plough. How to use and maintain agricultural machinery? Recently, the relevant agricultural machinery experts introduced to farmers' friends the knowledge of using several kinds of commonly used agricultural machinery for spring farming. rice transplanter 1. Replace the engine oil. For a rice transplanter that has been used for one season or 50 hours, engine oil should be replaced, and four-stroke gasoline engine oil can be purchased at a motorcycle accessory shop. 2. Clean the carburetor and purchase the cleaning agent at the motorcycle accessories store. At the same time, wash the sediment cup. Add fuel to start the engine commissioning equipment. 3, check whether the needle and the planting fork are deformed and collapsed, if the deformation can be corrected with a flattener. The forks are to be opened and the needles are sled straight and parallel. The clearance between the fork and the needle is about 1 mm. 4. Check and adjust the main clutch handle pull wire, pull plug handle pull wire, lifting handle pull wire and steering clutch pull wire clearance and sensitivity, if not sensitive or the clearance is too large, the adjustment nut will be adjusted. At the same time, some oil is dripped in these cable holes to increase flexibility. 5. Move the machine to the shore every day when the work is done. Rinse the mud on the rice transplanter with water and then drive it back to the garage. 6. As described above, check the shape and clearance of the correction pin and the insertion fork, and apply butter. At the same time, apply butter on the upper and lower rails and the moving parts. 7, check the engine oil surface, fuel tank oil surface, hydraulic oil surface, insufficient to add. 8. Add a proper amount of butter oil and a 1:1 mixture of engine oil in the hole of the implanting section and the insertion arm rubber plug hole. 9. Put all the moving parts, screws, and metal parts on the rice transplanter into the warehouse to prevent rust; the handles are in the open and fall positions. Pull a few drops of engine oil. Tiller 1. After the engine is started for the first time, heat engine operation is performed for 5 minutes. Keep the load running at a low speed before the engine is hot, and do not operate at full load or at low speed and no load. 2, to avoid overloading operation. The engine cannot run at full load during the running-in period. It can be run at a speed of 3000 rpm and a load of about 50%. 3. Change the oil on time. After the engine is running for 20 hours, the heat engine will change the oil, otherwise it will not be able to drain the residual oil in the body. After changing the oil for 20 hours, change the oil every 100 hours. 4. If the fuel mixes with water and dirt, it can cause the diesel engine to run abnormally or cannot be used as a vehicle. If there is water and dirt in the fuel, the fuel should be stored in a clean container and allowed to settle for more than 2 hours. Then use a hose or pump to pump the fuel out. The oil at the bottom of the container should not be used. 5, the choice of oil. It is very important to choose the right oil. If the used oil grade is not suitable, it will cause the piston ring to stick and burn the piston ring; the rapid wear of the cylinder sleeve; the rapid wear of the bearing and other moving parts will shorten the life of the diesel engine. 6, keep the air filter cleaner. If there is a lack of engine power and the smoke color deteriorates, replace the air filter or purge the core. The first cleaning of the filter element is to use 100 hours, the second time is to use 500 hours, and the filter element is replaced after 1000 hours. 7, common troubleshooting (1) It is not possible to make a car - check whether there is oil in the fuel tank, whether the fuel is clean, check whether the fuel tank switch is on, and check whether the fuel injector is fueled. (2) It is difficult to start - whether the pressure relief handle is opened; whether the engine oil is marked according to the refueling; whether the crankshaft bearing is worn badly; whether the cylinder sleeve is "pulled". (3) Insufficient engine power—Incorrect intake during oil supply; incorrect valve clearance; failure to reach standard compression ratio; insufficient air intake. tractor 1. Do not start to lift the clutch. Slowly release the clutch pedal while properly increasing the throttle. Otherwise, it will cause impact on the clutch assembly and transmission parts, and even damage. 2. The tractor is forbidden to open the gear or step down the clutch to slide downhill. 3, tractor shift and working speed selection. Choosing the correct working speed of the tractor will not only achieve the best productivity and economy, but also extend the life of the tractor. When the tractor is working, it should not be overloaded frequently and the engine must have a certain power reserve. The speed of tractor field work should be chosen so that the engine is working under about 80% load. 4, under normal circumstances, should first reduce the engine throttle, and then step on the main clutch pedal, and then gradually depress the driving brake operating pedal, so that the tractor stopped. In case of emergency braking, the main clutch pedal and the service brake operating pedal should be depressed at the same time. During driving, the driver is not allowed to place his or her foot on the brake or clutch pedal. Special reminder: When the tractor is driving on the road, the left and right brake pedals must be interlocked. When the tractor is parked on the slope, it is necessary to hang up the gear before releasing the brake pedal after the engine is turned off, hang the forward gear when going uphill, and hang up the gear when going downhill. 5. When the tractor is working in a heavy field in the field or working on a damp, soft soil, it is usually attached to the front drive axle to realize four-wheel drive operation. When the tractor is used for general transportation on hard roads, it is not allowed to engage the front drive axle, otherwise it will cause early wear of the front wheels. The main indicator for judging the nutritional value is the content of protein, while oyster mushrooms are rich in protein and have the advantages of low fat and low sugar.Oyster mushrooms contain 18 amino acids needed by the human body. In particular, the 8 amino acids that the human body cannot synthesize are particularly high, of which lysine and arginine, which promote children's growth and intelligence, account for 9.4% of the total.
