A real-time control method for cutting depth of cutter head of sugarcane harvester

Abstract

The present invention provides a real-time control method of cutter knifing of a cane harvesting machine. The method comprises the following steps: the step 1, installing a detection device; the step 2, performing trial cut of a sugarcane field to obtain a relation curve p=f(t) and h=f(t); the step 3, controlling a system to perform preprocessing of the data to obtain the two-dimensional point cloud of the cutter load pressure P and the cutter knifing H in the walking speed V; the step 4, performing interpolation operation and correction of the two-dimensional point cloud to obtain the control parameters of the P-H relation curve in the V; the step 5, when H is invariant, the P and the V show the linear correlation or power function relation to obtain the feature data relation corresponding to the P, the H and the V in real through combination of the obtained control parameters of the P-H relation curve; and the step 6, when the sugarcanes are cut, the current H is obtained through the conversion of the detected V and P. The real-time control method of cutter knifing of the cane harvesting machine can obtain the cutter knifing H in real time through the load pressure P and the walking speed V to regulate the cutter knifing to an appropriate position through the cane harvesting machine in real time.

Description

technical field [0001] The invention relates to the field of sugarcane harvesters, in particular to a method for real-time control of the cutting depth of a cutter head of a sugarcane harvester. Background technique [0002] Sugarcane is one of the main crops in my country. Guangxi is the main production area of ​​sugarcane in my country. The sucrose production has exceeded 60% of the country. Due to the low degree of mechanization of sugarcane harvesting, the cost of sugarcane harvesting accounts for about 40% of the production cost of sugarcane. With the increase of labor costs year by year, the cost of sugarcane sugar production has also been rising, which has greatly affected the development of the sugarcane sugar industry; and the key bottleneck to realize the mechanization of sugarcane production lies in the mechanization of sugarcane harvesting. In the development and promotion of sugarcane harvesting machinery, there is a key technology that needs to be solved urgentl...
