Anti-winding disc strip soil preparation device

Abstract

The invention relates to an anti-winding disc strip soil preparation device, and belongs to agricultural machinery. A sawtooth disc stubble destruction knife is fixedly mounted on a driving shaft; side cutting edges are respectively and fixedly mounted on two side surfaces of the sawtooth disc stubble destruction knife; the width of each side cutting edge is 5cm-6cm; the inclined angle between theradius line of a plate type rotary tillage knife and the radius line of the sawtooth disc stubble destruction knife is 50-60 degrees; the width between outer end heads of the side cutting edges on two side surfaces of the sawtooth disc stubble destruction knife is 13cm-16cm; and the diameter of the sawtooth disc stubble destruction knife is 46cm-50cm. According to the anti-winding disc strip soilpreparation device disclosed by the invention, the sawtooth disc stubble destruction knife is adopted to complete the operations of destructing and cutting primitive root stubbles and straw on seedbed locations of a ridge platform; the side cutting edges on two sides are used for completing the operations of soil rotary tillage and soil breaking on a strip seedbed in a certain width; and the anti-winding disc strip soil preparation device disclosed by the invention has the characteristics of being novel in structure, simple and reasonable, low in manufacturing cost, good in processed seedbedquality, low in operation power consumption and reliable in usage.

Description

technical field [0001] The invention belongs to agricultural machinery, and mainly relates to an anti-winding belt-shaped land preparation device. Background technique [0002] In order to promote no-tillage or less-tillage sowing technology, at present, machetes, chisel-shaped knives, or straight knives are often used to perform rotary tillage operations on the stubble left on the original seed bed before sowing operations. The above-mentioned knife types not only have disturbances The problems of large soil volume and power consumption, easy entanglement of grass, and high failure rate, especially the deep plowing and deep plowing caused great damage to the soil, which affected the popularization and application of advanced agronomic techniques for no-tillage or less-tillage sowing; but due to The reasons for straw mulching on the original stubble land have brought problems such as easy blockage, easy entanglement of grass, and poor quality of seed beds to no-tillage sowin...

Problems solved by technology

[0002] In order to promote no-tillage or less-tillage sowing technology, at present, machetes, chisel-shaped knives, or straight knives are often used to perform rotary tillage operations on the stubble left on the original seed bed before sowing operations. The above-mentioned knife types not only have disturbances The problems of large soil volume and power consumption, easy weed entanglement, and high failure rate, especially deep plowing and deep plowing caused great damage to the soil, which affected the popularization and application of advanced agronomic techniques for no-tillage or less-tillage sowing; but due to Straw mulching on the original stubble land has brought problems such as easy blockage, easy grass entanglement, and poor quality of seed beds to no-tillage sowing, which has affected the popularization and application of advanced agronomic techniques for conservation tillage.
