Description

Field of the Invention The present invention relates to the field of rice transplanters, and in particular to a high-speed electric rice transplanter and its use.

Paddy rice is an important crop in agricultural production, and about half of the world's population consumes rice as a staple food. Huge demand requires huge labor, but the use of labor is reduced to the extent that various rice transplanters are used. A rice transplanter is a cultivation apparatus for planting rice seedlings in a paddy field, and not only substitutes artificial planting work, but also improves rice planting efficiency and planting quality to a certain extent, achieving rational dense planting, Such planting is advantageous for mechanization of the subsequent work. The power source is an important composition of the rice transplanter, and the provision of the power source enables the rice transplanter to travel through the field and carry out a rice transplanting operation to plant a large quantity of seedlings in the paddy field. Conventional rice transplanters use fuel as a motive power, and fuel motive power has an advantage, but with continuous development of agricultural technology and environmental protection becoming more and more important, defects in fuel motive power become remarkable every day . The boarding type rice transplanter is an important part of the conventional rice transplanter. Compared with other rice transplanters, such rice transplanters need to provide the motive power necessary for traveling and work to the rice transplanter, and also need to provide motive power for boarding parts and workers. , The demand for power is higher.

Fuel power usually converts thermal energy produced by burning an engine fuel, such as diesel or gasoline, into mechanical energy. Based on the principle of power generation, a large amount of pollutants in the process of combustion of diesel or gasoline, such as benzene, toluene and xylene in exhaust, hydrocarbon oxides (NO), nitrogen oxides (NO), carbon monoxide (CO) It is known that sulfur dioxide (SO ₂ ), ozone (O ₃ ) and the like are generated. These contaminants not only pollute the environment but can also affect human health. Furthermore, in the process of planting work, both the operator and the power unit are in an open environment, and the power unit is close to a person, so the operator of the rice transplanter receives it compared with the opportunity to have an enclosed space such as a car. While direct injury is far greater than other fuel machine operators, the cost of purification of rice transplanter emissions is much lower than that of cars, considering production costs and technical difficulties. Thus, environmental pollution and health hazards are major problems for fuel field planters. In particular, with the emphasis on environmental protection and the search for environmentally friendly development methods, these problems are remarkable.

On the other hand, in response to the development of the power of automobiles, fuel machinery power is a technology that is already quite mature, but in view of its operation principle, the degree of complexity of fuel machinery is high and it is difficult to be simplified. As a result, the volume of the entire rice transplanter increases. And in the case of a boarding type rice transplanter, since it is necessary to provide the arrangement regarding boarding and the power for that, it is inconvenient for traveling and control because the volume is further increased. In addition, due to the complex mechanical structure and the fuel being carried, the relatively heavy weight of the boarding type rice transplanter itself adds to the degree of control difficulty in the complex planting terrain of the rice transplanter, requiring power requirements. Will also be high. The development of rice plant power has led to some extent to the development of the mechanical power of automobiles, but it also has to meet the demand for specific products. For example, while a car mainly travels on a road surface and arranges a vehicle structure having different motive power and design according to the road surface condition, a rice transplanter mainly performs rice planting work in a paddy field. Due to the special working environment of rice transplanters, there are special requirements for power sources. Rice planters, especially rice planters, generally work in the paddy field, and the cultivated soil is soft, which is a major difference from the working environment of other types of agricultural machines.
