Problems solved by technology

[0002] Harvesters often need to work across regions. Due to different regions and different soil topography, harvesters need to adjust the relevant mechanisms to adapt to the local terrain. At present, mechanical vehicles require agricultural machinery users to manually adjust the relevant components, and make appropriate adjustments based on experience. However, in actual operation, it cannot be guaranteed that the normal operation can be performed after the adjustment, and the adjustment may affect the driving speed, the impurity rate and breakage rate of the grain, the feeding amount of the harvester, etc., which will greatly affect the operation quality and efficiency.
[0003] The most relevant prior art to the present invention is the patent titled "Intelligent Adjustment System for Harvesters" (Patent No.: 201310198284.5). This patent can only adjust the torque of the drum during harvester operations to avoid clogging of the harvester. However, it cannot fundamentally guarantee the quality and efficiency of the work

Embodiment 1

[0042] An intelligent adjustment system for a grain harvester

[0043] Such as Figure 4 As shown, below the cab 3, a reel 4, a header 21, a threshing cylinder 23, a concave plate 5, and a sieve 31 are sequentially arranged from front to back, and a fan 26 is arranged between the threshing cylinder 23 and the concave plate 5. , the rear side of the driver's cab is provided with a granary and an elevator, and the elevator is used to transport the processed crops to the granary by the sieve 31, which is the prior art.

[0044]The grain detection unit includes a granary camera A18 and a granary camera B19, which are installed in the granary for taking images of the impurity content and broken rate of the grain in the granary; the reel speed sensor (fifth sensor) 11 is installed on the reel shaft , for detecting the rotating speed of reel 4 during operation; Drum speed sensor (the first sensor), is installed on the threshing drum 23, is used for detecting the real-time rotating s...

Embodiment 2

[0048] A control method for an intelligent adjustment system of a grain harvester

[0049] Such as image 3 As shown, the AI ​​control unit calculates the grain impurity content and broken rate according to the image information acquired by the granary camera and the elevator camera (grain grain detection unit); when the impurity content and broken rate exceed the set threshold, based on the corresponding The real-time data transmitted by the sensor judges the required matching screen opening, concave plate gap, drum speed, fan speed, reel speed, and operating speed values, and transmits the above required matching values ​​to the vehicle control unit; The car control unit adjusts the opening of the sieve, the gap between the concave plates, the rotating speed of the drum, the rotating speed of the fan, the rotating speed of the reel, and the operating speed to achieve the required matching values. Repeat the above steps of adjusting according to the impurity content of the g...

Embodiment 3

[0053] A control method for an intelligent adjustment system of a grain harvester

[0054] The driver selects the mode through the panel buttons, and there are two modes: walking mode and working mode. In the walking mode, the opening of the sieve, the gap between the concave plates, the drum speed, the reel speed, the fan speed, and the header height cannot be adjusted. The drum speed, reel speed and fan speed are zero, and the vehicle speed can be adjusted in real time. When working in the field, press the button to switch to the operation mode, and an intelligent adjustment system of the grain harvester officially starts to work. The control method in the working mode is the same as that in the second embodiment.

[0055] In the operation mode, the driver can view the specific parameter values ​​of each component in real time through the display, such as the drum speed value, the concave plate gap, the screen opening, the fan speed, the reel speed, the operation speed and ...

Abstract

The invention relates to an intelligent regulating system for grain harvesters and a control method thereof; an AI (artificial intelligence) control unit calculates grain impurity rate and breakage rate according to image information acquired by a grain bin camera and an elevator camera; when the impurity rate and the breakage rate exceed a set threshold, required matching values, including opening of a screen, gaps of a concave plate, rotating speed of a roller, rotating speed of a fan, rotating speed of a reel and operating speed are judged, and the required matching values are sent to a vehicle control unit; the vehicle control unit correspondingly adjusts the opening of the screen, the gaps of the concave plate, the rotating speed of the roller, the rotating speed of the fan, the rotating speed of the reel and the operating speed to arrive at the required matching values. The intelligent regulating system for grain harvesters is simple in structure and convenient to operate, and the operation quality and efficiency of the harvesters are effectively guaranteed.
