Resonant Excited Rotary Tiller Roller Anti-sticking Device and Rotary Tiller Equipped with the Same

Abstract

The invention discloses an anti-sticking device for rotary cultivator blade rollers based on resonance excitation, which includes an anti-sticking knife set, a resonance source device, a buffer device and a resonance adjustment device; the anti-sticking knife set consists of a plurality of soil scrapers It is connected with multiple anti-winding knives and can move along the axial direction of the cutter shaft as a whole; the resonance source device includes a resonance unit and a concave-convex vibration device; the resonance unit includes a first support, a resonance shaft and a sleeve A resonant spring on the resonant shaft; the surface of the concave-convex vibrating device is provided with a concave-convex sliding surface around the cutter shaft; one end of the resonant shaft is connected with the anti-stick wrapping knife group, and the other end is close to the concave-convex sliding surface; The resonance adjustment device uses a screw nut mechanism to adjust the concave-convex structure of the concave-convex sliding surface. The present invention also provides a rotary tiller equipped with the above-mentioned rotary tiller roll anti-sticking device. The invention utilizes the rotating power of the knife roller to generate vibration without an external drive source, can solve the problem of clay and entanglement in real time, and improves the efficiency of the rotary tillage operation.

Description

Technical field [0001] The present invention relates to a civi-tiller, in particular, refers to a resonant excitation, a rotary tumor roller anti-adhesive wrapper and a civi-cultivation machine having it. Background technique [0002] The water content of rice in the middle and lower reaches of the Yangtze River is large, and the soil wet sticky, the spiral machine is easy to attach to the rotary torque roll when the rice field is homework. The spiral knife roller adhesion soil, there is a problem after winding rice: the surface is easy to adhere to the soil, winding rice causes congestion, affecting the quality of operation, working efficiency and service life; the cost of operation is expected to affect agriculture; unit drive the machine and The adhering soil rice is jointly doing, increasing the work resistance and energy consumption. [0003] The existing rotary tiller knife roller anti-stick method can be divided into: mechanical desorption technology, surface engineering t...

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.
