Soil breaking, scattering and ditching apparatus for no-tillage direct seeding suitable for use with rotary tiller

Abstract

A soil breaking, scattering and ditching apparatus for no-tillage direct seeding suitable for use with a rotary tiller comprises a transmission shaft connected with a power output shaft of the rotarytiller, a rotary cutter assembly fixed on the transmission shaft and a guide plate mounted on the rotary tiller; the rotary cutter assembly is fixed on the transmission shaft through a cutter shaft; the rotary cutter assembly comprises a first bent cutter, a second bent cutter and a wall-cutting straight cutter which are mounted on the cutter shaft; the first bent cutter comprises a plurality of first right-angled bent tools symmetrically distributed along the center of the cutter shaft and having a linear cutting edge. The new scattering rotary tool layout is used herein, a cutter radius andbutterfly soil-breaking guide device is also used, a ditching mode is improved, soil throwing uniformity, soil breaking rate and ditching rate are increased, and ditching depth may reach 15-25 cm; thesoil breaking, scattering and ditching apparatus is simple in structure, convenient to apply to various rotary tillers, low in cost, convenient to assemble and disassemble, and higher in ditching quality and efficiency.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a device for throwing broken soil and ditching for direct seeding and no-tillage matching with a rotary tiller. Background technique [0002] Agricultural intensification and mechanization are inevitable trends in the development of modern agriculture. For crop rotation, stubble, no-tillage and direct seeding, research on ditching technology corresponding to it has emerged. In southern paddy field agricultural production, ditches and drainage in the field to lower the groundwater level are important measures for high-yield winter crops such as green manure and rapeseed. The clods excavated during the excavation of the drainage ditch shall not hinder the germination of the sown seeds or the growth of the stubble crop seedlings as much as possible. Therefore, it is required that the ditching equipment should be as finely divided as possible for ditching and soil th...

AI Technical Summary

Problems solved by technology

[0003] The emergence of mechanical trenching machines has solved the shortcomings of manual trenching such as low efficiency and unstable trench shape.

However, in traditional mechanical ditching devices, furrowing plows and chain ditching devices are likely to cause the soil on both sides of the ditch to accumulate into ridges and the shape of the ditch is unstable, thereby affecting the growth of crops in rotation by the ditch; the disc ditching device exists The ditch shape is narrow and the soil is thrown unevenly, which affects the leveling of the field; the utility model patent of "a kind of broken soil throwing and ditching device matched with a rotary tiller" applied to the State Intellectual Property Office on November 21, 2016 (application No.: 201621250866.9) and invention patent (Application No.: 201611029140.7) can efficiently complete ditching operations, but there are disadvantages such as large clods of soil thrown away for ditching, uneven soil spreading, unsuitable thickness of covering soil and unsuitable width of throwing soil
