Rotary blade roller anti-sticking and anti-twining device based on resonance excitation and rotary cultivator with rotary blade roller anti-sticking and anti-twining device

Abstract

The invention discloses a rotary blade roller anti-sticking and anti-twining device based on resonance excitation. The rotary blade roller anti-sticking and anti-twining device comprises an anti-sticking and anti-twining blade set, a resonance source device, a buffering device and a resonance adjusting device. The anti-sticking and anti-twining blade set is formed by connecting a plurality of soilscrapers and a plurality of anti-twining cutters, and can integrally move along the axial direction of the cutter shaft; the resonance source device comprises a resonance single body and a concave-convex oscillation starting device. Each resonance single body comprises a first support, a resonance shaft and a resonance spring arranged on the resonance shaft in a sleeving mode. A concave-convex sliding surface is arranged on the surface of the concave-convex oscillation starting device around the cutter shaft; one end of the resonance shaft is connected with the anti-sticking and anti-twiningblade set, and the other end of the resonance shaft clings to the concave-convex sliding surface; and the resonance adjusting device adopts a lead screw nut mechanism to adjust the concave-convex structure of the concave-convex sliding surface. The invention further provides a rotary cultivator with the rotary blade roller anti-sticking and anti-twining device. Vibration is generated by utilizingthe rotating power of the knife roll, an additional driving source is not needed, the problems of clay and winding can be solved in real time, and the rotary tillage operation efficiency is improved.

Description

Technical field [0001] The invention relates to a rotary tiller, in particular to a rotary tiller knife roller anti-sticking device based on resonance excitation and a rotary tiller with the same. Background technique [0002] The rice stubble fields in the middle and lower reaches of the Yangtze River have high water content and wet and sticky soil. When the rotary tiller works in the rice stubble fields, the sticky and wet soil is easy to adhere to the rotary cutter roller. The following problems exist after the rotary cutter roller adheres to the soil and entangles the rice stubble: the surface of the machine is easy to adhere to the soil, and the entanglement of the rice stubble causes congestion, which affects work quality, work efficiency and service life; shutdown and cleaning are time-consuming and laborious and affect the farming time; The adhered soil and rice stubble do work together, which increases operation resistance and energy consumption. [0003] According to the...

AI Technical Summary

Problems solved by technology

After the rotary cultivator roller adheres to the soil and entangles the rice stubble, there are the following problems: the surface of the machine tool is easy to adhere to the soil, and the entanglement of the rice stubble causes congestion, which affects the operation quality, work efficiency and service life; the shutdown and cleaning are time-consuming and laborious and affect the farming time; the unit drives the machine tools and The adhered soil rice stubble works together, increasing the working resistance and energy consumption

However, its complex structure is inconvenient to disassemble and assemble, and the thrown debris is easy to adhere to the sliding belt and the rotary blade shaft to cause blockage, and the anti-winding blade cannot cut off the weeds entangled on the rotary blade seat

[0005] Chinese patent ZL201720091566.9 discloses a rotary tiller with an anti-wrapping device, which cuts weeds by adding a strip-shaped anti-wrapping component between the rotary blade seats or between the rotary blades, but the rotary tiller throws The amount of soil is large, and the soil is easy to adhere to the anti-wrapping parts, which affects the cutting quality. It is only suitable for areas with low soil moisture content, and it is difficult to meet the rice stubble fields with wet and sticky soil and a large amount of straw.
