Automatic copying follow-up system of sugarcane harvester and control method thereof

Abstract

The invention discloses an automatic copying follow-up system of a sugarcane harvester and a control method thereof. The automatic copying follow-up system comprises a displacement sensor device whichis installed directly behind a sugarcane supporting mechanism, the sugarcane supporting mechanism is fixed to the front end of a sugarcane supporting mechanism lifting device which is installed at the front end of a cart and is connected with a sugarcane-supporting hydraulic control device, a root cutting device is installed in the center of the front lower part of the cart and is connected witha root-cutting hydraulic control device, and a ridge height detection device used for detecting the height change between the cutter at the bottom of the root cutting device and the sugarcane ridge inreal time is installed at the middle bottom of the cart. The automatic copying follow-up system is a closed-loop control system and can be used for automatically copying and carrying out sugarcane harvesting operation, so that the head breaking rate of sugarcane is greatly reduced, and the waste is reduced.

Description

technical field [0001] The invention relates to an automatic profiling follow-up system for a sugarcane harvester. In addition, the present invention relates to a sugarcane harvester with such an automatic profiling follow-up system, and a control method for the automatic profiling follow-up system for the sugarcane harvester. Background technique [0002] The profiling system of the existing sugarcane harvester usually works by means of terrain survey wheels, that is, the terrain survey wheels are used to walk on the bottom of the ditch of the sugarcane row to measure and estimate the working height of the root cutting device. For example, the Chinese utility model patent with the publication number of CN201621247569.9 discloses a "terrain imitation system for a sugarcane harvester chopping device", which drives the terrain imitation swing arm to rise and fall according to the terrain height in real time through the detection wheel, and the imitation terrain swings The arm...

Problems solved by technology

[0004] In order to overcome the sugarcane harvesting machinery in the prior art in the root cutting process, the cutting knife is too low to easily lead to the high rate of perennial root breakage, the second year The perennial root germination is reduced or unable to germinate, or the perennial roots left during cutting are too high to cause waste, etc., The invention provides an automatic profiling follow-up system of a sugarcane harvester and a control method thereof, which can automatically perform profiling of the cane-supporting mechanism and the root cutting device of the sugarcane harvester as the height of the sugarcane field changes, and can greatly reduce the damage of the perennial roots of the sugarcane. Waste caused by high head rate or root stay
