Description

Intelligent environment-friendly multifunctional rotary cultivator

Technical Field

The application belongs to the technical field of multifunctional rotary tillers, and particularly relates to an intelligent environment-friendly multifunctional rotary tiller.

Background

In combination with the actual conditions of the current rural areas, the phenomenon of burning straw and crop straws is common for a considerable part of peasants in China in order to save labor and trouble, and the smoke of the peasants not only pollutes the atmosphere, but also seriously affects the environmental sanitation and the health of people. In recent years, government authorities have forced to ban this practice by sending out a plurality of papers, but farmers have had little success because they cannot find a way to dispose of straw. Related scientific researchers consider that pollution sources are broken, and the environmental chronic disease is thoroughly and radically cured, one of which is to effectively treat the crushed straws by scattering the straws into soil and forcing the straws into the soil, so that the straws are forced into the soil under the gravity compression of machinery, so that the straws are decomposed and deteriorated in mud and are converted into humic substances to become farmyard manure. Through the process, not only can the environmental pollution problem of the straws be solved, but also the organic fertilizer of the soil is added, so that the aim of changing waste into valuables is fulfilled. The conventional soil tillage machine has the steps of ploughing and soil preparation, namely ploughing and raking, wherein the work can only be performed by removing or burning rice straws before ploughing, and the rice straws can be wound around the machine, so that the machine cannot work smoothly. Thus, it is one of the time-consuming and environment-polluting processes due to miswork; secondly, the traditional tillage machine needs manual driving and active operation, which is time-consuming, labor-consuming, low in efficiency and resource-wasting; moreover, the traditional farming machine has single function and cannot be used for multiple purposes, so that the cost of purchasing the machine by farmers is high, the economic burden of the farmers is increased, the yield and income cannot be increased, and the enthusiasm of the farmers is influenced.
