Description

Electric hand-held rice transplanter and its application

Technical field

The invention relates to the field of rice transplanters, and further relates to an electric hand-held rice transplanter and its application.

Background technique

Agriculture is the foundation of human survival and development, providing people with the most basic life guarantee. With the development of science and technology, the agricultural production mode has also been continuously improved. From the primitive cultivation methods of artificial and animal power, it has gradually turned into a mechanized production mode, which has greatly liberated the production labor force and improved production efficiency.

In the existing mechanical agricultural machinery, the fuel power source directly replaces the traditional human and animal power driving modes, and drives the agricultural machinery to perform different agricultural production actions. Therefore, the power source is an important component of the mechanical agricultural machinery. The rice transplanter is one of the mechanical agricultural machines and its important type of agricultural machinery. Corresponding to the development of mechanical power, most of the existing mechanical agricultural machinery power uses fuel machinery as the power source. In the long-term application process, fuel machinery brings many benefits to people and saves a lot of labor, but at the same time, it has its own drawbacks, and it is also an aspect that people pay more and more attention to: environmental pollution.

Conventional fuel machinery typically uses the engine to convert thermal energy from fuel combustion into mechanical energy, typically diesel or gasoline. It is well known that based on the principle of power generation, diesel or gasoline produces a large amount of pollutants during combustion, such as benzene, toluene and xylene, nitrogen oxides (NO), carbon monoxide (CO) in hydrocarbon (HC) tail gas, Sulfur dioxide (SO ₂ ) and ozone (O ₃ ). These pollutants not only pollute the environment, but also directly affect human health. 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.
