New changes in agricultural science and technology

With the rapid development of science and technology, driverless technology is no longer limited to urban roads, and is gradually penetrating into the agricultural field. Overseas driverless tractors are becoming the new darling of agricultural production and attracting much attention.

In large-scale farm operations, the advantages of driverless tractors are fully demonstrated. Take the large farms in the Midwest, where farmland is vast, often thousands of acres. Traditional tractor operations require a lot of manpower and time, while driverless tractors can achieve efficient and accurate operations. According to statistics, the use of unmanned tractors for large-scale farm operations can increase the efficiency of operations by more than 30%, while reducing labor costs by about 50%.

In orchards and vineyards, where terrain is complex and requires a high level of refinement, driverless tractors also perform well. In some vineyards, conventional tractors are more difficult to operate because of the undulating terrain. Equipped with advanced sensors and intelligent control systems, the unmanned tractor can automatically adjust its driving speed and working attitude according to the terrain, ensuring stable operation on complex terrain such as hills. In the orchard, the driverless tractor can also be used to carry the fruit, and through the connection with the logistics system in the orchard, the automatic transportation of the fruit from the picking point to the storage point is realized, which improves the management efficiency and economic benefits of the orchard.

It is foreseeable that driverless tractors will occupy a more important position in the future agriculture and become a key force to promote the modernization, intelligent and sustainable development of agriculture. It will not only change the mode of agricultural production, but also bring new development opportunities and changes to the agricultural industry, and help global agriculture move towards a new era of more efficient, green and intelligent.

The development of agricultural machinery

In recent years, the development of Chinese agricultural machinery can be described as advancing by leaps and bounds. From the plain to the mountains, from the south to the north, the figure of agricultural machinery can be seen everywhere. The data show that the comprehensive mechanization rate of crop cultivation and harvest in the country has reached a relatively high level, and the mechanical tillage rate, mechanical sowing rate and mechanical yield rate have been significantly improved. In some large agricultural provinces, such as Heilongjiang, Henan and other places, the application of large agricultural machinery is extremely extensive, large-scale farms, large tractors, combine harvesters and other equipment efficient operation, greatly improve the efficiency of food production.

In the future, we should increase investment in agricultural machinery research and development, promote technological innovation, so that agricultural machinery can better adapt to the needs of different regions and different crops. At the same time, strengthen the training of farmers to improve their operational skills and application level of agricultural machinery.

Bulldozer routine inspection and maintenance

Before work, check the appearance, check whether the outside of the machine is cracked, deformed or damaged, check whether the bolts and nuts of each connection part are loose. At the same time, check the level of fuel, oil, coolant and hydraulic oil to ensure that they are in the normal range. Also look at the blade of the bulldozer to ensure that it is securely connected and the cutting edge is not excessively worn.

During the work, pay attention to observe the instrument and indicator light, monitor the oil temperature, water temperature, oil pressure and other indicators through the instrument panel, observe the indicator light to find the fault signal in time. And pay attention to the working state of the machine, listen to the engine and transmission system whether there is abnormal noise, feel the operation of the machine is smooth.

After the end of the work, to clean up the bulldozer, brush and other tools to remove the fuselage of dirt, dust and other debris, focus on cleaning the radiator and the engine surface to avoid overheating. Also check the wear of easily worn parts, such as tracks, blades, etc., to find problems in time for replacement or repair.

Hydraulic system of tractor

Tractor hydraulic system is mainly used to lift and control agricultural machinery.

It is generally composed of a hydraulic tank, a hydraulic pump, a control valve, a hydraulic cylinder and a connecting pipeline. The hydraulic pump is responsible for pulling the hydraulic oil out of the tank and creating pressure. The control valve can adjust the flow direction and pressure of the hydraulic oil to control the action of the hydraulic cylinder. Hydraulic cylinder is the actuator, through the hydraulic oil to push the piston, to achieve the lifting of farm tools and other actions.

For example, when a mounted plow needs to be lifted, a hydraulic pump delivers hydraulic oil to a hydraulic cylinder, and a piston extends under the oil pressure to lift the plow. The hydraulic oil in the system also plays the role of lubrication and power transmission, and can buffer vibration to ensure the stable operation of the system.

Maintenance of tractor engine

The specific items of tractor engine maintenance are as follows:

  1. Change the oil and oil filter

Drain the old oil and clean the impurities at the oil filter seat and drain plug.

Install new oil filter and tighten according to specified torque.

Add new oil that meets the tractor specifications and check that the oil level is within the normal range.

  1. Check and replace the air filter

Take out the air filter element and check its pollution level. If the filter element is too dirty or damaged, it should be replaced in time.

Clean the inside of the air filter housing to ensure that there is no dust and debris.

  1. Check and adjust the valve clearance

Use a gauge to measure the valve clearance and adjust it according to the tractor model and technical requirements.

Ensure that the valve clearance is within the specified range to ensure the normal working performance of the engine.

  1. Check the fuel system

Check the fuel filter, if there is blockage or pollution should be replaced in time.

Check whether the fuel line is leaking, aging or damaged, and repair or replace it in time if there is a problem.

Clean the fuel tank to remove water and impurities from the bottom.

  1. Check the cooling system

Check the coolant level, if insufficient, add it in time.

Check whether the radiator, water pipe, and water pump are leaking, blocked, or damaged.

Clean the dust and debris on the surface of the radiator to ensure good heat dissipation.
