Embodiment 1

[0121] Embodiment 1: An embodiment of adjusting the reel speed and cutter frequency.

[0122] The reel and cutter are respectively connected to their respective hydraulic motors through transmission chains, and the hydraulic motors are connected to the hydraulic pumps through proportional valves. The control module outputs analog signals to control the proportional valves, thereby controlling the speed of the hydraulic motors, and finally realizes the speed and speed of the reel. Adjustment of cutter frequency.

Embodiment 2

[0123] Embodiment 2: an embodiment of header height adjustment.

[0124] The header is connected to the hydraulic cylinder, the hydraulic cylinder is connected to the hydraulic pump through the flow control valve and the direction control valve, the flow control valve controls the speed of the hydraulic cylinder movement, the direction control valve controls the direction of the hydraulic cylinder movement, and the output signal of the control module controls the flow control valve And the directional control valve, so as to control the movement of the hydraulic cylinder, and finally realize the adjustment of the header height.

Embodiment 3

[0125] Embodiment 3: An example of adjusting the position of the reel.

[0126] Two groups of electric push rods, each group has one electric push rod on the left and right; one group is vertically fixed on the header frame, and one end is connected with the reel support frame; the other group is parallelly fixed on the reel support frame; each An electric push rod receives the analog signal from the control module, and pushes the reel to move up and down, back and forth, and finally realizes the adjustment of the position of the reel.

[0127] Those skilled in the art should understand that the embodiments of the present invention may be provided as methods, systems, or computer program products. Accordingly, the present invention can take the form of an entirely hardware embodiment, an entirely software embodiment, or an embodiment combining software and hardware aspects. Furthermore, the present invention may take the form of a computer program product embodied on one or m...

Abstract

The invention discloses a control device and control method for operating parameters of a cutting table of a combine harvester and belongs to the field of automation of agricultural harvesting machinery. The control device comprises a forward speed monitoring module, a crop status monitoring module, a control module and a man-machine interaction module; the crop status monitoring module is used for acquiring optical images of crops, extracting plant height, density, stubble and lodging degree information and sending the same to the control module; the control module controls the rotation speedof a reel according to the forward speed and a speed ratio model of the machine, the position of the reel according to the plant height and lodging degree, the cutting frequency according to the forward speed of the machine and the crop density degree and the height of the cutting table according to the height of stubble; the man-machine interaction module with the manual automatic switching function displays monitoring data in real time and controls the operating parameters of the cutting table through buttons. Through manual button control and intelligent automatic adjustment of the operating parameters of the cutting table system, better performance of the combine harvester is achieved, and intelligence level and efficiency of harvesting are improved.

Description

technical field [0001] The invention belongs to the field of agricultural harvesting machinery automation, and in particular relates to a control device and a control method for operating parameters of a combine harvester header. Background technique [0002] A combine harvester is a machine that is the application of electromechanical-hydraulic integration technology in agricultural harvesting. Intelligent control is the application of artificial intelligence theory and technology, the use of operational research optimization methods, combined with control theory methods and technology, in an unknown environment, imitating human intelligence to achieve control of the system. The intelligent control of the combine harvester includes the intelligent control of the harvesting operations of wheat, rice, corn, rapeseed and other crops. [0003] During the combined harvesting operation, the manipulator mainly observes the growth of the crops in front of the header, judges the pl...
