Problems solved by technology

Although the cost of the grain unloading system is low, frequent replacement of fuses or relays during operation will seriously affect work efficiency and increase the difficulty of harvesting
And manual removal of debris that causes blockage has a high risk factor, and at the same time increases the labor intensity of the driver in the harvesting work

Embodiment 1

[0046] Such as figure 1 and figure 2 Commonly shown, a kind of intelligent grain unloading control system, comprises grain unloading motor 1 and auger transmission shaft 2, unloading grain motor 1 is installed on one end of auger transmission shaft 2, and auger transmission shaft 2 is installed in unloading cylinder ( Not shown in the figure), the unloading grain motor 1 is used to drive the auger transmission shaft 2 to rotate so that the grain a is unloaded from the grain unloading port 3 of the grain unloading cylinder, (while bracts b, stalks c, weeds d Will wind the auger drive shaft 2). Besides, the grain unloading control system also includes a control module, a grain unloading switch electrically connected with the control module, a display module and an alarm module.

[0047] The grain unloading switch can be installed in the cab or at the grain unloading port 3 position of the unloading cylinder, and is used to activate the grain unloading function in the control ...

Embodiment 2

[0056] Such as image 3 and Figure 4 Commonly shown, this embodiment provides an intelligent grain unloading control method using the above-mentioned intelligent grain unloading control system, the intelligent grain unloading control method includes the following steps:

[0057] S1. Initialize the internal parameters of the control module, and set the initial value n=1.

[0058] S2. Determine whether the grain unloading switch is in the ON state, if yes, execute step S3; if not, end the procedure.

[0059] S3. The current acquisition unit in the control module collects the current value I of the grain unloading motor 1 every ΔT time n ;Incremental operation of n, execute plus 1 operation, n=1,2,3,4.....

[0060] S4. The control processing unit in the control module collects the current value I every time ΔT n Carry out differential operation to calculate △I n ; Among them, △I n The calculation formula is: △I n =(I n+1 -I n ) / △T.

[0061] S5. Judgment △I n Whether i...

Abstract

The invention discloses an intelligent control system and control method for unloading grain. The control system for unloading the grain includes a control module, a grain unloading motor, a display module, and an alarm module; a grain unloading switch is opened to start a grain unloading function of the control module, which means that the control method for unloading the grain is executed; the control module collects a current value of the grain unloading motor every [delta]T time, and performs operational analysis on the collected current value; it is judged that current of the grain unloading motor is in a rising trend, the current value exceeds a maximum current value, the continuous running time for the grain unloading motor under the condition of exceeding the maximum current valueexceeds a preset [delta]Tmax, the grain unloading motor is immediately stopped and alarm and warning are given out, then the grain unloading motor reversely rotates for a period, and the u grain unloading motor continues to forwardly rotate for performing grain unloading operation. The system and the method can effectively prevent damage of the grain unloading motor, can also intelligently judge an operation condition of the grain unloading motor, controls reversal rotation of the grain unloading motor to cancel a blockage situation of an auger, avoids the danger of manual removal of debris, and enables the working efficiency to be improved.

Description

technical field [0001] The invention belongs to the technical field of harvester unloading grain, in particular to an intelligent grain unloading control system and control method. Background technique [0002] With the development of agriculture, the use of harvesters is becoming more and more extensive. During the harvesting operation, due to the limitation of the size of the granary, the harvester needs to unload grain from time to time. Such as figure 1 As shown, most of the current grain unloading systems use the grain unloading motor 1 to drive the auger drive shaft 2 to unload the grain a from the grain unloading port 3 of the grain unloading cylinder; The difference in the separation degree of threshing and threshing will cause the auger to be often entangled by debris such as bract leaves b, crop stalks c, weeds d, etc. The accumulation of debris to a certain extent will cause the auger to be blocked. After the load capacity of the grain unloading motor is exceeded...
