Problems solved by technology

[0006] When the edamame harvester works at different driving speeds, the edamame harvesting area per unit time is also different. If the harvesting speed of the harvesting device cannot match the driving speed, the harvesting efficiency and effect will be very poor.

Embodiment 1

[0038] like image 3 The speed acquisition device shown includes speed sensors 2-13, 2-23, 2-33, and adopts inductive proximity switches; the hydraulic motors include walking hydraulic motors 1-3 and hydraulic motors 2-13, 2-23, 2-33;

[0039] like figure 1 As shown, the method for controlling the harvesting speed of the edamame harvester in this embodiment includes the following implementation steps:

[0040] 1) When the edamame harvester is in working condition, use the speed sensors 2-13, 2-23, 2-33 to monitor the speed pulse signals M of the hydraulic motors 2-13, 2-23, 2-33 of the harvesting device 2 R ;

[0041] 2) Extract the 1-3 speed pulse signal M of the walking hydraulic motor Z , calculate the rotational speed pulse signal M required by each hydraulic motor of the harvesting device 2 D , judge the required speed and the actual speed;

[0042] 3) Use the PID function to calculate the current A required by the electromagnetic valves 2-11, 2-21, and 2-31 of the ...

Abstract

The invention relates to a method and device for controlling harvesting speed of an edamame harvester, and the method comprises the following steps of 1) when the edamame harvester is in operation, using a rotation speed sensor to monitor rotation speed pulse signals MR of a walking hydraulic motor and each hydraulic motor of a harvesting device; 2) extracting the rotation speed pulse signal MZ ofthe walking hydraulic motor, calculating the rotation speed pulse signal MD required by each hydraulic motor of the harvesting device, and judging the required rotation speed and the actual rotationspeed; and 3) calculating current AD required by a proportional valve of each hydraulic motor of the harvesting device by using the PID function, so as to control the rotation speed of each hydraulicmotor. By obtaining the traveling speed, the rotation speed of each motor of the harvesting device is judged, so that the harvesting efficiency and traveling speed are matched to achieve a better harvesting effect.

Description

technical field [0001] The invention relates to the field of control, in particular to a method and system for controlling the harvesting speed of a soybean harvester for calculating the speed of a harvesting device according to the traveling speed of the soybean harvester. Background technique [0002] Edamame harvester is a kind of professional harvesting equipment in the agricultural machinery industry. The more common harvesting equipment are wheat harvesters and rice harvesters. Unlike traditional harvesting equipment that uses hard shaft transmission: engine, drive shaft, clutch, working parts. The edamame harvester adopts a hydraulic travel motor to drive the crawler to rotate to realize the travel function. During the harvesting operation, lower the header, turn the roller brush, brush off the soybeans and leaves, and transport them to the top of the barn through the conveyor belt, and use the fan to separate the leaves and soybeans. Edamame fell into the barn smo...
