Description

[Name of invention established by ISA according to Rule 37.2] Agricultural machinery power system and its electric device and agricultural machinery with agricultural machinery power system Technical field

The invention relates to the field of electric agricultural machinery, in particular to an agricultural machinery power system and an electric device thereof, a monitoring unit and an application, and an agricultural machine with an agricultural machinery power system.

Background technique

Agriculture is the foundation of the existence and development of human society. With the continuous development of social economy and the continuous advancement of science and technology, the agricultural production methods of human society are constantly improving, and the agricultural production methods are based on primitive artificial and accumulative farming methods. Gradually developed into a mechanized production mode, the emergence of agricultural machinery not only greatly improved the efficiency of agricultural production, but also liberated a large number of labor and reduced the labor intensity and burden of agricultural workers.

Today's agricultural machinery is driven by internal combustion engines, such as rice transplanters, seeders, transplanters, plant protection machines and other agricultural machinery. The internal combustion engine is its only source of power, in which the internal combustion engine will work with oil (such as diesel, gasoline or biomass). Oil) is converted to kinetic energy to provide power. In this process, fuel such as diesel or gasoline has a low combustion rate, so that a large amount of pollutants are generated, such as benzene, toluene and two in hydrocarbon (HC) tail gas. Contaminants such as toluene, nitrogen oxides (NO), carbon monoxide (CO), sulfur dioxide (SO ₂ ), and ozone (O ₃ ), or pollutants such as solid particles, which not only pollute the environment, but also directly affect agriculture. The health of the workers. More importantly, in the agricultural production process, on the one hand, the operator and the power part are placed in an open environment, and the distance between the power part and the person is relatively close, so the machine with relatively closed space such as a car, the agricultural machine The direct injury to the operator's body is much greater than that of other fuel machinery operators; on the other hand, due to manufacturing costs and technical difficulties, the degree of purification of agricultural machinery exhaust is much lower than that of automobiles. Therefore, environmental pollution is a great drawback of the existence of fuel machinery, especially in the case of today's increasing emphasis on environmental protection and efforts to seek an environmentally friendly development approach.

On the other hand, although fuel mechanical power is already a fairly mature technology, based on its basic working principle, the mechanical complexity of fuel machinery is high and difficult to reduce, and combined with various mechanical working parts in agricultural machinery, This makes the entire mechanical agricultural machine larger in size, and it is not convenient to walk and control.

Further, the complex mechanical degree and the way of fuel make the existing mechanical agricultural machinery itself have a larger weight. Based on the specific production operation mode, some production operations require manual operation, and the mechanical weight is undoubtedly an important factor affecting the convenience of operation. In terms of it, it takes a lot of physical strength.

The development of an agricultural machinery product cannot be separated from the development of other related technologies, but at the same time it must be combined with its specific product requirements. For example, the development of mechanical agricultural machinery is inseparable from the development of power sources in the automotive field, but because of the different working environments and different application requirements, mechanical agricultural machinery cannot directly apply automotive power sources. The rice transplanter is an important type of many mechanical agricultural machines. It also has various drawbacks mentioned above. At the same time, due to its own special production environment, there are special requirements for the power source. As we all know, transplanting machines, especially rice transplanters, generally work in paddy fields and the land is soft. This is the biggest characteristic of the working environment of rice transplanters different from other types of agricultural machinery. Therefore, the waterproofness of power source is important to consider. aspect.

In summary, there is a need for an alternative fuel system that addresses environmental pollution, bodily injury, and ease of operation. And other drawbacks, and can be combined with the transplanter for this specific production operation.
