Description

A small rotary tiller with functions of weeding, ditching, sowing, fertilization and backfilling

technical field

The utility model relates to agricultural mechanization, in particular to a multifunctional small rotary cultivator.

Background technique

Compared with developed countries, my country's agricultural machinery is still relatively backward. The United States and other developed countries began to actively promote large-scale land management in the early 20th century, and realized the replacement of human and animal power by mechanical force. In the 1970s, comprehensive mechanization was realized. After entering the 1990s, global satellite positioning systems were widely used in agricultural production. Among them, the equipment level of agricultural workers has approached or exceeded that of industrial workers. At present, my country still implements small-scale operations based on farmers and households. Although agricultural machinery has been promoted and applied to a certain extent, manpower, animal power, and traditional farming habits and farming methods still dominate. According to statistics from the International Yearbook, the average area of cultivated land per economically active population in my country is 0.2 hectares, accounting for 44.1% of the world's average level and 0.7% of the US average level; the amount of chemical fertilizer used per thousand people is 64.6 tons, slightly higher than the average level in Asia. But only 67.5 percent of the world average and 1.2 percent of the U.S. average. Although the application of science and technology in agricultural production is increasing year by year, the breadth and depth of application are far from enough. In this form, to improve the agricultural level of our country, it is necessary to implement agricultural mechanization, but for the current situation of small-scale operations in our country, it is very difficult to implement large-scale planting machinery.

Existing rotary tillers can only plow and harrow the land, and the fertilization and seeding operations in farming still need to be done manually, which is time-consuming and labor-intensive.

Therefore, the utility model provides a novel multifunctional small-sized rotary tiller, which has the characteristics of convenient operation, small volume, low energy consumption, wide applicability, etc., and is quite beneficial for popularizing agricultural mechanization.
