Description

TECHNICAL FIELD

[0001] The utility model relates to the field of improvement of agricultural machinery, especially to an agricultural operation vehicle applicable to different operation requirements. BACKGROUND

[0002] China is a traditional agricultural country, since the 1970s, the household contract responsibility system has been implemented, the development of agriculture is not only closely related to the interests of farmers, but also an important part of the national overall strategy of poverty reduction and well-off society, but due to the accelerating process of urbanization in China, most young people in mountainous areas have turned to city work, resulting in a shortage of rural labor.

[0003] With the population settling in urban areas, the rural population is declining, and the land is abandoned (abandoned phenomenon refers to the phenomenon of not cultivating suitable land and actively leaving it idle and barren), this phenomenon is particularly common in China's mountainous areas, the main reason is that the natural conditions of the land are poor, the land is barren, the land is fragmented, and mechanized farming is difficult to achieve, resulting in low productivity and poor land efficiency, and further leading to the phenomenon of abandonment. Because young people have turned to city work, the remaining middle-aged and elderly farmers are even more unable to cultivate. According to the statistical data released by the national agricultural department, among the hilly and mountainous counties in China, the total area of cultivated land is 4668.60 million mu, accounting for 34.62% of the country. It can be seen that the development of agriculture in hilly and mountainous areas is of great significance to the transformation of China's agricultural industry. If mountainous agricultural machinery can be used in the agricultural production of hilly and mountainous areas, it will significantly improve the yield and quality of crops, help to ensure China's food security, and promote rural revitalization.

[0004] Under the prior art, considerable efforts have been made to solve this problem, under the premise of ensuring production efficiency and improving crop yield, using mechanical equipment instead of traditional agricultural labor, while saving labor, more effectively utilizing resources, and reducing the labor burden of agricultural personnel.

[0005] However, the existing agricultural machinery still faces some problems: such as lack of versatility, long idle time, and agricultural machinery production is limited by crop types, resulting in short working time of single type of agricultural operation device, and most of the time is in an idle state. Such mechanical idling not only cannot play a large role in the mechanical function, resulting in waste of equipment, but also requires additional maintenance during the idle period, such as improper maintenance, rust and failure, which may lead to non-use when used again the next year, making some mechanical equipment become consumables, which need to be repeatedly purchased or repaired, resulting in poor economic benefit. The land planting households in the mountainous areas, which have relatively low benefits, are even more difficult to bear. UTILITY MODEL CONTENT
