Reel rotating speed adjusting device for reducing harvesting loss and control method

Abstract

The invention provides a reel rotating speed adjusting device for reducing harvesting loss and a control method, a reel is provided with a reel adjusting device, and the reel rotating speed adjusting device further comprises a sensor, a hydraulic motor, a stepping motor, a controller and a height adjusting device; the hydraulic motor is used for driving the reel turntable to rotate; the height adjusting device is used for adjusting the height of the reel; the controller determines a reel speed ratio and judges whether the radius of the reel or / and the height of the header or / and the mounting height of the reel needs to be adjusted or not according to the reel speed ratio; the controller determines a target value of the rotating speed of the reel according to the advancing speed of the header; the controller obtains the output quantity through a fuzzy PID algorithm according to the rotating speed difference between the target value and the actual rotating speed of the reel, and the controller controls the proportional electromagnetic valve to adjust the opening degree according to the output quantity. When different crops are harvested, the rotating speed of the reel is matched with the advancing speed, the failure rate of the harvester is reduced, and header loss is remarkably reduced.

Description

Technical field [0001] The present invention relates to the field of agricultural production, and Background technique [0002] As an important part of the cutting platform, the turn speed of allocation will increase the impact on the grain, the speed is too slow, and the plants will be pushed down to increase the loss of grain. [0003] The prior art has a matching speed and advancement speed, but it does not consider that different cutting bench is high or different crops affect the speed ratio of the allocation, causing incorrect adjustment, and impossible to completely change the loss of losses. Inventive content [0004] In response to the deficiencies in the prior art, the present invention provides a graft wheel speed adjustment device and a control method for reducing the harvest loss, and the gram speed is matched to the forward speed when the harvesting of different crops is matched. Stability control lays the foundation, reducing the failure rate of harvester, signifi...

Problems solved by technology

[0002] As an important part of the header, if the reel speed is too high, it will increase the impact on the grain. If the speed is too slow, the plant will be pushed down by the cutter, which will increase the loss of grain.

[0003] In the prior art, there is a matching between the reel speed and the forward speed, but it does not take into account the different influences of different header heights or different crops on the reel speed ratio, resulting in inaccurate adjustment and unable to completely change the problem of large losses
