Embodiment Construction

[0047] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0048] The corn harvester comprises a cab, an engine 8, a gearbox 19, a grain conveying auger 20 and a drum 21.

[0049] Such as figure 1As shown, a high moisture content corn harvesting drum speed control system of the present invention adopts CAN bus to collect and transmit data, which increases the reliability and security of data transmission. The CAN network has 6 nodes in total, which are respectively: Main controller 10, display 7, joystick 6, keypad 5, grain broken sensor 4 and engine 8.

[0050] The main controller 10 is used to complete basic controls such as starting and stopping of the corn harvester, walking and steering, and automatic control of the rotating speed of the drum and the speed of the vehicle. The display 7 is used for parameter setting, data storage, and displaying information such as operating parameters, conventional vehic...

Abstract

The invention belongs to the field of agricultural automation, and in particular relates to a high-moisture-content corn harvesting roller rotation speed control system and a control method. The control system comprises a CAN bus, a measurement transmitting device, a main controller, a hydraulic execution mechanism, an armrest box assembly and a display. A CAN bus integration technology is adoptedin the invention; on the basis of the CAN bus, corn harvesting quality parameter online detection and sensing information processing, and fault diagnosis systems are integrated; the real-time property and the reliability of information transmission of the control system are ensured; due to stepless regulation of an electro-hydraulic proportional valve, the working intensity of a driver is lightened; the operability of a corn harvesting machine is improved; due to multi-sensor fusion adjustment, the roller rotation speed adjsutment reliability and scientificity are ensured; and thus, the roller rotation speed control in a harvesting process is relatively reasonable and accurate.

Description

technical field [0001] The invention belongs to the field of agricultural automation. Specifically, it relates to a high moisture content corn harvesting drum rotation speed control system and control method. Background technique [0002] The corn harvester is the main machine for corn harvesting. Corn harvesters are mainly divided into two categories: ear picking machines and grain direct harvesting machines. The grain direct harvesting machine has changed the traditional corn harvesting process of first harvesting the ear and then drying and threshing, which greatly reduces the labor load, reduces the occupation of the site for the ear drying, and improves agricultural productivity and production efficiency. Direct harvesting of corn grains has been generally realized abroad, but in China, due to the short harvest period of corn, the high moisture content of the grains during harvest is likely to cause great damage and loss of grains, which is severely restricted. The t...
