In order to reduce people's labor intensity, the rice threshing work is performed using a mobile rice thresher, which can also improve work efficiency. The supporting power of the thresher is mostly a small gasoline engine and consumes a lot of gasoline during use. In order to save oil, reduce operating costs and reduce environmental pollution, we now introduce the oil-saving techniques of the rice thresher in operation for the reference of farmers. Rice single-tree thresher plays an important role in experimental sampling.
1. Improve the hole diameter of the oil inlet hole of a gasoline engine. Use a steel ball with a diameter of 3 mm to place in the oil inlet hole of the gasoline engine's measuring hole, and gently tap the steel ball with a wooden hammer to make the original amount of oil inlet hole 0.6 mm. The aperture is reduced to 0.4 mm. This improvement can save 15% to 20%.
2. Appropriately reduce the oil level in the gasoline engine carburetor. In the hot weather and high temperature season, the fuel tank should not be overfilled. At the same time, adjust the bracket so that the float protruding hole is 2 3 3 mm high. The oil level in the float chamber of the gasoline engine of the gasoline engine was reduced to 8} 9 mm in the original 11 mm, which could save about 5% of the fuel.
3. After the anti-gasoline gasoline engine is refueled, the fuel tank cap should be tightened to prevent it from being wasted compared to gasoline. Gasoline storage barrels should be covered with a sealed lid and placed in a fireproof, anti-theft safe place. After the quarterly threshing operation is completed, the remaining gasoline in the petrol engine tank should be put into the petrol bucket for storage.
4. The working speed should be selected medium-speed small gasoline engine rated speed is generally 5000 rev / min, when threshing rice, do not use the big throttle, high-speed operation, as long as the rice can be off the net on it. The rice threshing experiments conducted by farmers in the suburbs of Nanchang have confirmed that the use of medium throttle and intermediate speed (ie between 25,003,500 rpm) can save oil 5%, and can also meet the needs of rice grain threshing.
5. Reducing petrol engine idling time When paddy rice threshering is performed on a rice single-strand threshing machine, the rice should be cut down first and then piled into a pile. The gasoline engine should then be started. The mountain 2 thresher operators should perform threshing operations continuously, and do not cut and thresh in the field. As a result, the petrol engine idles and wastes oil. If operating on the threshing yard, the rice stalks prepared for threshing should be stacked together, and the gasoline engine should be started nearby. The two people should continue to thresh operation. Attention must be paid to fire prevention during operation.
6. Timely maintenance and maintenance of gasoline engine Rice single threshing machine operators must carefully check, clean, adjust and repair the gasoline engine in accordance with the provisions of the gasoline engine instruction manual, so that the gasoline engine is in a good technical condition, good start-up performance, high dynamic performance, oil Low consumption). At the same time, the thresher machine parts should be maintained after each shift, such as removing the drum wrapped around the grass, filling the bearing with butter on time, etc., in order to achieve the purpose of high efficiency, high quality, low consumption, and safety of the threshing operation.
