Problems solved by technology

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

Embodiment 1

[0044] like figure 2 As shown, the LK-G150A laser displacement sensor 4 produced by Keyence Corporation of Japan is installed directly above the cutter head 1 of the sugarcane harvester to sample the cutter head 1. The cutter head 1 is driven by a hydraulic motor 2 through a gearbox 3. The laser displacement sensor 4 is composed of a measuring head and a controller. The maximum sampling frequency is 50KHz, and the input voltage is 24V. When the sampling frequency is set to 5KHz, it can accurately measure the position of the cutterhead 1 and output electrical signals;

[0045] The laser displacement sensor 4 collects the vibration displacement data in real time within the sampling time t, obtains the time-domain waveform of the vibration displacement, and then performs statistical processing to obtain the vibration peak-to-peak value h within the sampling time t; see for details image 3 ;

[0046] Through manual measurement and collection of a series of data on the number of...

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 a cutterhead of a sugarcane harvester. Background technique [0002] In recent years, the results of sugarcane mechanized harvesting experiments in my country have shown that after mechanical harvesting of sugarcane, the perennial roots of sugarcane are seriously damaged and the cutting quality is poor, resulting in reduced or no germination of perennial roots in the next year, affecting the growth and development of the next year, and greatly affecting sugarcane production and economy. benefit. 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...
