It exceeded the development target of 400 billion yuan set in the 12th Five Year Plan, an increase of 73.55% compared to the end of the 11th Five Year Plan. The total number of major indicators of the agricultural machinery industry has already ranked among the top in the world. The role of technology in supporting the transformation and upgrading of agricultural machinery industry is significant. The technological innovation capability of China's agricultural machinery industry has significantly improved. The further improvement of the industrial technology innovation system with enterprises as the main body, market orientation, and the combination of industry, academia, and research has promoted the development of agricultural machinery industry into a new stage.

1. Tips for using agricultural machinery in spring

Spring returns to the earth, and various agricultural machinery will begin to engage in field operations. Due to the weather and the inherent characteristics of the machinery, improper use in spring can easily lead to the "disease" of agricultural machinery. In order to improve work efficiency, reduce usage failures, and ensure safe production, in addition to operating agricultural machinery according to regulations, attention should also be paid to the following aspects.

1.1 Clean before use. Lubrication, adjustment, fastening and other work must be done well to ensure that the machinery is put into operation in good technical condition, thereby avoiding the occurrence of stagnation and looseness between components caused by long-term disuse and idle of agricultural machinery in winter.

1.2 Due to the recent temperature rise in spring, the brittleness of metal components in agricultural machinery is still strong. Therefore, the maintenance of lubrication systems in agricultural machinery operations must use lubricants according to prescribed standards to ensure that the thermal coefficient and viscosity are moderate. Special attention should be paid to maintenance cycles and standards, and filter components should be regularly cleaned or replaced in a timely manner to ensure wear and tear.

1.3 The heat dissipation components must be well insulated to avoid excessive engine cooling, reduce engine operating pressure, and lower fuel consumption.

1.4 After the agricultural machinery operation is completed, the machinery should be placed in a sheltered and warm shed. If it is parked outdoors; The battery must be removed to prevent it from freezing due to changes in weather and temperature.

2. How to use the summer rice harvester

2.1 Strictly prevent excessive temperature in the power unit. In summer, the high temperature directly affects the horsepower of the power unit. If encountering a "boiling" of the power unit during use. Mainly due to water shortage in the water tank. But cooling water cannot be added immediately, as it may cause the cylinder head and cylinder block to explode. Z is good to stop running, slow down, and gradually add clean cooling water when the water temperature drops to around 70 degrees. Overloading not only causes the water temperature to rise rapidly, but also damages the components. Therefore, in general, the load should be controlled at around 90%, leaving 10% as a load reserve to cope with short-term overload caused by uphill and changes in farmland resistance.

2.2 Strictly prevent the use of incorrect fuel. The viscosity of lubricating oil generally changes with high or low temperature. If the temperature increases, the viscosity will decrease. So in summer, it is necessary to switch to diesel engine oil with higher viscosity. In addition, diesel with a suitable solidification point grade for the operating environment should be selected. Not only is the price low, but it can also reduce costs.

2.3 Strictly prevent high tire pressure. During the high temperature season, there is a significant temperature difference between day and night. Due to the increase in temperature, the volume of air thermal expansion also increases, causing tire pressure to rise, which can lead to tire rupture and unnecessary economic losses. So summer tires should generally be inflated 5% -7% lower than winter tires, and it is never allowed for the air pressure to be higher than the standard tire pressure.

2.4 Prevent excessive scale buildup in the power unit. If the scale on the water jacket of the power unit is too thick, it will reduce the heat dissipation efficiency by 30% -40%, causing overheating of the power unit and deterioration of its operation. The horsepower decreased and the fuel injector got stuck, resulting in a serious production accident. So it is necessary to regularly remove scale. To maintain good cooling performance.

2.5 Strictly prevent the fan belt from being too loose. When working at high temperatures, the tension of the fan belt decreases, leading to belt slippage and increased transmission loss, making the belt more susceptible to damage. Therefore, in summer, adjusting the tension of the power fan belt is usually slightly higher than the standard value when the car is cold.

2.6 Prevent air blockage in the oil brake pipeline. Most transport tractors generally use hydraulic brakes. When the temperature is high in summer, the oil brake pipe produces air resistance, which affects the braking effect. Therefore, the brake oil should be sufficient during use, and the pipeline should not leak. If air resistance occurs, the air must be exhausted.

2.7 Anti fuel system air resistance. The higher the temperature, the faster the fuel evaporates, and it is easy to form air resistance in the oil circuit. Generally, the oil circuit of diesel engines is not tight, and air leakage causes air resistance. So the oil circuit must be unobstructed to prevent oil leakage during production. If there is air resistance in the oil circuit, it is necessary to stop and cool down, and turn the manual oil pump to exhaust the air in the fuel filter and oil circuit through the exhaust hole, so that the oil circuit is filled with fuel.

2.8 Prevent circuit oxidation and malfunction. Due to the high temperature and humidity in summer, the battery will produce water vapor and hydrogen gas during operation. If the vent is blocked, it will cause the internal pressure of the battery to rise and explode. Regular dredging is important. In high temperature and high humidity air, the battery is extremely prone to oxidation, resulting in poor contact, causing the entire vehicle to run out of power, making it difficult to start, and electrical system failures. Firstly, remove the terminal post from the pole post, then polish the oxide layer with sandpaper or saw blade, clean it thoroughly, and install it securely. To strictly prevent the pole from oxidizing again. After installation, it is necessary to apply Vaseline and lubricating grease to isolate the air.

2.9 Prevent the battery from running out of water during use. Regularly check the electrolyte in summer, with the liquid level generally 10-15 millimeters above the height of the electrode plate; After adding distilled water multiple times, it is necessary to regularly check the electrolyte density to keep the battery in good working condition.

3. Common problems in the maintenance of agricultural machinery during spring plowing

3.1 Oil pan oil only looks at quantity, not quality. Drivers generally only know how to replenish engine oil but do not attach importance to quality inspection. Long term use of engine oil contains a large amount of oxides and metal shavings, resulting in reduced lubrication performance and wear of parts.

2. Only maintain the air filter, not the muffler and exhaust pipe. Some drivers do not timely clean the carbon deposits in the exhaust pipes and mufflers, resulting in excessive carbon deposits, reduced exhaust cross-sectional area, incomplete exhaust gas discharge, and less fresh air intake, leading to combustion deterioration.

3. Just add cooling water without considering the cooling effect. Due to the driver's lack of diligence in removing scale, even with sufficient cooling water, the cooling effect is poor.

4. Only focus on the quality of the plunger assembly and fuel injector needle valve assembly, without observing the quality of the fuel valve assembly. The main function of the oil outlet valve is to seal, which separates the plunger oil chamber from the high-pressure oil pipe to prevent backflow; The second is to quickly stop the depressurization and fuel supply, ensuring that the fuel injector cuts off completely.

5. The driver only focuses on the condition of the valves and valve seats, without considering the quality of the valve springs. When the valve leaks, only the valve and valve seat are often checked. Not valuing the quality of valve springs during testing.
