Dynamic real-time cutting depth control method based on load of sugarcane harvesting mechanical cutterhead

Abstract

The invention discloses a dynamic real-time cutting depth dynamic real-time control method based on a load of a sugarcane harvesting mechanical cutterhead. The method comprises the following steps of: 1, arranging a data measurement device on a sugarcane harvester, and sampling on a cutter; 2, acquiring and processing data, namely when the cutting depth of a certain cutterhead is h, acquiring data of load pressure P in real time, and performing statistical processing on the data; 3, adjusting the cutting depth h of the cutterhead, repeating the step 2, and obtaining the corresponding data of the load pressure P; 4, drawing a curve according to the cutting depth h of the cutterhead and the data of the load pressure P, and thus obtaining a linear equation of the cutting depth h of the cutterhead and the data of the load pressure P; and 5, outputting a processing result of the linear equation obtained in the step 4 to a sugarcane harvesting mechanical power control system. The method is simple, practical and easy to implement; and under the condition of guaranteeing the cutting depth, aims of greatly reducing the power of the cutterhead during cutting and guaranteeing the quality of a perennial root can be fulfilled.

Description

technical field [0001] The invention belongs to the technical field of sugarcane harvesting machinery, and in particular relates to a dynamic real-time control method for cutting depth based on the load of the cutter head of the sugarcane harvesting machinery. Background technique [0002] Cane cutting cutter head is one of the important parts of sugarcane harvester. In order to ensure the flatness of the perennial root section of sugarcane after harvesting, it is usually required to cut the stubble below 2 to 3 centimeters from the ground. An important condition for maintaining a low head-breaking rate is to ensure that the rotation speed of the cane cutting cutter head changes little, and the cutting depth of the cane cutting cutter head will not be idling or even stuck due to the sudden deepening of the cutting depth. However, due to the unevenness of cane ridges and cane furrows, the cutting depth of the sugarcane cutter head will change continuously during the harvestin...

Problems solved by technology

According to the knowledge of the inventor, most of the current research direction for this problem is to improve the structure of the cutter, and there is no cutting depth through the cutter head, and the power output is controlled, that is, the power of the cutter head is in the cutting process while ensuring the cutting depth. Relevant literature reports on the research direction of greatly reducing and ensuring the quality of perennial roots
