The tiller is powered by a small diesel engine or gasoline engine, and has the characteristics of light weight, small size, and simple structure. The micro-tiller is widely used in dry land, paddy fields, orchards in plains, mountainous areas and hills. Equipped with corresponding equipment, it can perform operations such as water pumping, power generation, spraying, spraying, etc., and can also be towed for short-distance transportation. The tiller can be used freely in the field, which is convenient for users to use and store, eliminating the need for large agricultural machinery to be inaccessible. The troubles of mountain fields are the best choice for farmers and consumers to replace cattle farming.
The working environment of the tiller is actually very harsh. It is easy to generate friction and vibration between the parts during the working process, oil, mud, and water attack, which will inevitably cause the wear of the parts, loose connections, corrosion and aging, etc. Therefore, it is very important to learn the operation and maintenance of the tiller. Below, we will share with you the maintenance related knowledge of the tiller.
Maintenance system of micro tillage machine
Because the working environment of the tiller is relatively harsh, maintenance is particularly important. During the work of the tiller, due to the friction and vibration of the parts and components, the invasion of oil, mud and water will inevitably cause the wear and tear of the parts;
Loose connection, corrosion and aging. As a result, the technical condition of the tiller has deteriorated, the power has decreased, the fuel consumption has increased, the wear has accelerated, and the failures have continued to appear. In order to prevent the occurrence of the above situation, it is necessary to strictly implement the maintenance system of "prevention is more important than cure, and care is more important than repair".
The maintenance misunderstanding of the micro-tiller
[Air-cooled machine uses water to cool down]Some operators see that the air-cooled machine has a high temperature and are worried about damaging the machine, so they use watering to help cool down. In fact, it is a very wrong approach. When the temperature is suddenly cooled with water, the cylinder liner suddenly shrinks, it is easy to pull the cylinder, break the ring, or even the cylinder liner rupture; do not pay attention to maintenance. Some operators think that it is enough to do maintenance every few days. In fact, wear and tear is a process that accumulates day by day, and shift maintenance is just as important.
[Not paying attention to the quality of fuel and lubricating oil] Poor fuel quality not only makes the machine power insufficient, but also accelerates the wear of the oil pump and the core sleeve; the quality of the lubricating oil directly affects the start-up performance and service life of the machine, so you must not be careless . Lu Qibing from Shahe Village, Yaowan Township, Yichang City, reported that his machine has been working very well. It was because of a lack of lubricating oil during one operation, and a renewed oil was added. As a result, the performance of the machine was completely degraded, and the problem was finally solved after an overhaul;
[Improper use of sealant for the partial cover gasket of the engine] After the partial cover gasket is used with the sealant, the excess glue easily enters the gear box. Due to the long-term work and the suction of the oil pump, the sealant can easily block the oil inlet hole of the engine, causing the crankshaft to and The connecting rod cannot be effectively lubricated; the fuel tank cap leaks with a thin film paper. After the fuel tank is sealed, negative pressure will be generated in the fuel tank after working for a long time, resulting in insufficient fuel intake, causing the machine to emit black smoke and insufficient power when working.
[Poor diesel atomization only oil change nozzle] In addition to the problem of the oil nozzle, poor diesel atomization is mostly caused by high-pressure oil pump wear, low pressure, and low oil volume; dismantling the wind deflector and baffle of the air cooler indiscriminately. Some operators do not know the function of the windshield and the windshield, and think it is something that keeps the mud, but they can be disassembled at will, so that the wind of the fan cannot be concentrated and the cooling effect is lost;
[Randomly tighten the screws on the body] Mini tillers are mostly equipped with engines with aluminum alloy boxes. The hardness of aluminum alloy is obviously lower than that of ductile iron. Therefore, all screws on the body must be tightened according to the specified torque, especially the cylinder head screws. , A little carelessness will "draw". And try not to tighten the screws when the engine is warming up.
