Description

Technical Field

[0001] The utility model relates to the technical field of fertilizer spreaders, in particular to a tillage and soil-building fertilizer spreader. Background Art

[0002] Intertillage and soiling are a crucial component of tobacco cultivation and a key measure for increasing tobacco leaf yield. Intertillage and soiling have the advantages of loosening the soil, regulating water and fertilizer supply, and improving soil moisture, air, and heat conditions. There are two main methods for soiling: manual and mechanical. Manual soiling is inefficient, making mechanical soiling the primary method. Currently, most domestic soiling machines are small-scale soiling machines used with walk-behind tractors. These machines include spiral, disc, and coulter types, with the Zhongnong brand soiling machines produced by Zhongnong Machinery being among the most advanced. Existing soiling machines struggle to achieve high soiling heights; soil flow is difficult to control, which can damage seedlings; and their low efficiency makes them inadequate for large-scale field operations. Therefore, there is an urgent need to develop new, efficient, and safe soiling machines to ensure increased tobacco leaf yield and quality.

[0003] With economic development and industrialization, research and development of large-scale agricultural machinery has been rapid abroad. For example, some developed countries in Europe began researching machinery for cultivating tall crops during the intertillage period early. Because land is more concentrated and plots are larger, these machines are primarily used with high-powered tractors, featuring high levels of automation and high efficiency. Most of these machines are tractor-type, integrating multiple functions and boasting a wide working width. In recent years, some types of intertillage machinery have achieved working widths approaching 20 meters. For example, Howard's mounted rotary cultivator features a variety of rotary blade types, each rotating unit capable of varying widths by controlling the number of blades. To cope with uneven terrain, ensure consistent tillage depth, and facilitate transportation, most wide-field cultivators are foldable, hydraulically controlled, and feature a frame that can be articulated in groups of three, five, or more, making them suitable for working on large plots of land. Foreign machines are affected by land conditions and have more working units, a wider working width, greater power requirements, and higher working efficiency. However, land plots in China are generally small, and foreign large machines are not suitable for domestic conditions.

[0004] With the development of the national economy, the progress of industrialization, and the introduction of a series of agricultural machinery subsidy policies to increase support for agriculture, the development of field management machinery during the tillage period has made great strides. This has evolved from single-function tillage machines to multifunctional combined-operation machines, from hand-held tillage machines to mounted tillage machines, and from driven working components to driven working components. Domestic universities and research institutes have also conducted extensive research to address issues such as soil compaction, which can cause large clods to crush seedlings, low weed control efficiency, and weed entanglement and blockage of working components. Liu Chao and others at Northeast Agricultural University have designed a flue-cured tobacco tillage and soil-building machine. The machine consists of a rotary tillage blade assembly, a ridging shovel, a ridging shovel beam, a swinging rotary tillage hood, and a fixed rotary tillage hood. During operation, the rotary tillage blade assembly breaks up the soil and removes weeds. Soil flow is controlled by adjusting the angle of the deflector on the swinging rotary tillage hood, and the penetration depth of the ridging shovel can be adjusted according to agronomic requirements. Wang Yingbo and colleagues at Northeast Agricultural University have designed a driven potato tiller, primarily composed of a rotating unit, a protective shield, and a suspension frame. The rotating unit comprises a soil-breaking blade, left and right cutter discs, and a loosening blade. During operation, power is transmitted from the tractor to an intermediate gearbox, and then to the rotating unit to carry out the work. A loosening blade is also included to reduce resistance to soil penetration and improve penetration efficiency. A protective shield on the rotary blades breaks up spilled soil particles. The Agricultural Machinery Research Institute of the Xinjiang Academy of Agricultural Reclamation Sciences has developed the 3XZF.5 rotary tillage and topdressing machine. The complete machine consists of a transmission mechanism, frame, fertilizer tank, gearbox, rotary blades, a soil-raising device, and contoured wheels.

[0005] In summary, how to design a fertilizer spreader that can complete multiple operations such as tillage, furrowing, fertilizing, and soiling at one time is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content
