Description

The present invention relates to the field of electric agricultural machinery, and particularly to an agricultural machinery power system and its electric device, monitor unit, application, and agricultural machine including an agricultural machinery power system.

It is no exaggeration to say that agriculture is the foundation of the existence and development of human society, and with the sustainable development of socio-economics and the advancement of science and technology, the agricultural production methods of human society are constantly being improved, and human power and livestock are being improved. The cultivation method used is changing to the mechanized production method, and the advent of agricultural machinery not only greatly improved the efficiency of agricultural production, but also released a large number of labors and reduced the burden on agricultural workers.

Traditional agricultural machinery, such as rice planters, seeders, transplanters, plant protection devices, and other agricultural equipment, is driven by the power supplied by the internal combustion engine, and is the only internal combustion engine. As a power source, the internal combustion engine provides power by converting oil (for example, diesel, gasoline or bio-oil) into kinetic energy during operation, and in such a process, fuel such as diesel and gasoline Due to its low combustion rate, pollutants such as benzene, toluene, xylene, nitrogen oxides (NO), carbon monoxide (CO), sulfur dioxide (SO ₂ ), and ozone (O ₃ ) in hydrocarbon compound (HC) exhaust. A large amount of pollutants such as internal combustion engines and solid particles are generated, which not only pollutes the environment but also directly affects the health of agricultural workers. Furthermore, in the agricultural production process, both the operator and the power part are placed in an open environment, and the distance between the power part and the person is relatively short, so compared to a machine with a relatively closed space such as an automobile. Therefore, while the direct damage to the body of the operator of the agricultural machine is much greater than that of the operator of other fuel machines, the degree of purification of the exhaust gas of the agricultural machine from the viewpoint of manufacturing cost and technical difficulty. Is much lower than a car. Therefore, environmental pollution is a major drawback of fuel machinery, and in today's world where environmental protection has been emphasized and environmentally friendly development is expected, such a drawback is particularly remarkable.

On the other hand, fuel mechanical power is already a fairly mature technology, but based on the basic operating principle, the mechanical complexity of fuel machinery is high and difficult to reduce, and various mechanical work parts in agricultural machinery. When combined with, it makes the whole agricultural machine larger and difficult to drive and control.

In addition, complex mechanical degrees and fuel-based methods have made traditional agricultural machines themselves heavier, and some production operations require manual operation, depending on the specific production method. However, the weight of the machine is definitely an important factor that affects the convenience of work, and it is necessary to spend a lot of physical strength.

The development of agricultural machinery products is inseparable from the development of other related technologies, but at the same time must be combined with the requirements of specific products. For example, the development of power of agricultural machinery depends on the development of power sources in the automobile sector, but agricultural machinery cannot directly apply the power source of automobiles because the working environment and application requirements of agricultural machinery and automobiles are different. Rice transplanters are an important type of many agricultural machines, and at the same time have the various drawbacks mentioned above, but also have special requirements for power sources due to their own special production working environment. As is well known, rice transplanters, especially paddy rice transplanters, are generally used in paddy fields and have soft cultivated land, so the waterproofness of the power source is the biggest feature that is different from the working environment of other types of agricultural machinery. This is an important aspect to consider.

As mentioned above, a rice transplanter that can replace the conventional fuel system, can solve environmental pollution, physical damage, inconvenience in operation, etc., and meets the needs of specific production operations such as rice transplanting. Expected.
