Cutting quality evaluation method and device based on vibration of cutter head of sugarcane harvester

Abstract

The invention discloses a cutting quality evaluation method and device based on sugarcane harvesting machine cutter head vibration. The method comprises the following steps that multiple sampling times t are set, and rotating speeds of a cutter head of a sugarcane harvesting machine in different sampling times t are set to be different; multiple vibration displacement data of the cutter head during sugarcane cutting in the sampling times t are collected in real time through a laser displacement sensor, and multiple vibration peak values h of the cutter head are obtained according to the vibration displacement data; evaluation parameters of the parts, left in soil, of cut sugarcane in all the sampling times t are collected, and multiple first comprehensive scores Y of the part, left in the soil, of the cut sugarcane are obtained according to the evaluation parameters; a cutting quality evaluation curve is obtained according to the vibration peak values h and the corresponding first comprehensive scores Y; evaluation indexes of the sugarcane cutting quality are obtained according to the cutting quality evaluation curve. According to the cutting quality evaluation method and device based on sugarcane harvesting machine cutter head vibration, real-time online evaluation on the cutting quality is achieved, and a large quantity of reference data is provided for sugarcane harvesting machine maintenance and farmer planting.

Description

Technical field [0001] The invention relates to the technical field of sugarcane harvesting machinery, in particular to a cutting quality evaluation method and device based on the vibration of the cutter head of a sugarcane harvester. Background technique [0002] In recent years, the results of my country's mechanized sugarcane harvesting test showed that after the sugarcane was harvested mechanically, the ratoon roots of the sugarcane were seriously damaged and the cutting quality was poor, which caused the following year to reduce or fail to germinate. benefit. Broken head rate is an important indicator of cutting quality. Among the various types of sugarcane harvesters used in China, whether it is a foreign or domestic model, the broken head rate when cutting sugarcane is generally as high as 20%. Some models are not Cutting into the soil is even as high as 90%, and the excessively high rate of breakage means that farmers' planting costs have doubled. At present, it is diffi...

The broken head rate is an important indicator of the cutting quality. Among the various types of sugarcane harvesters used in China, whether it is a foreign model or a domestic model, the broken head rate when cutting sugarcane is generally as high as 20%, and some models are very Cutting into the soil can even be as high as 90%, and the high broken head rate means that the cost of planting for farmers will double
