Embodiment Construction
[0054] Such as figure 1 As shown, a method for self-adaptive control of infinitely variable speed of the drum according to the embodiment of the present invention includes the following steps:
[0055] S1. Before the harvester performs harvesting operations, self-check the belt connected between the infinitely variable speed wheel 200 and the drum 300 of the harvester, obtain the belt wear amount, and judge whether the belt wear amount is within the preset belt Within the wear threshold range, if so, enter the adaptive control mode;
[0056] S2. In the adaptive control mode, acquire the first displacement of the variable speed wheel disc 230 of the continuously variable transmission wheel 200, the actual rotational speed of the continuously variable transmission wheel 200 and the first rotational speed of the drum 300;
[0057] S3. Calculate the first theoretical rotation speed of the drum 300 according to the first displacement and the actual rotation speed of the infinitely...

The invention relates to a method for self-adaptive control of stepless variable speed of a drum, a control system and a harvester thereof. The self-inspection of the belt is carried out to determine whether to enter the self-adaptive control mode. After entering the self-adaptive control mode, the first Rotational speed, and according to the first comparison result obtained after comparing the first rotational speed with the first theoretical rotational speed, and then control the driving speed of the harvester according to the first comparison result, so as to ensure the feeding amount of the drum, so that The drum is maintained in a better speed range, and can continue to harvest, realizing self-adaptive adjustment, reducing the driver's work intensity to a certain extent, and at the same time, reducing the driver's manual intervention in the harvesting process, with better The human-computer interaction improves the intelligence of the harvesting operation. At the same time, to a certain extent, the driver can better understand the wear degree of the belt, which is convenient for subsequent maintenance and management.
Description
technical field [0001] The invention relates to the technical field of harvesters in agricultural machinery, in particular to a method for self-adaptive control of infinitely variable speed of a drum, a control system and a harvester thereof. Background technique [0002] Harvesting machinery is an indispensable equipment in agricultural production. It is mainly used for harvesting wheat, corn, rice, soybeans and other crops. Its hydraulic working system consists of header lifting, reel lifting, grain unloading, hydraulic main clutch system and control The stepless drum speed change system of the drum speed, in which, if the drum speed is not properly controlled, the drum will be blocked, the drum threshing will not be clean, the grain breakage rate will be high, the cleaning loss rate will be large, and the entrainment loss will be large. Maintaining a constant range during the process is an important parameter for judging harvesting machinery performance. [0003] In the ...
