Problems solved by technology

The initial set speed will decrease with the harvesting operation process. Improper speed will cause the broken rate of seeds, unclean removal, large separation loss, and even failure problems such as drum blockage. Adjustments, often unable to achieve rapid and timely adjustments

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 rotational speed of the drum 300 according to the first displacement and the actual rotational speed of the conti...

Abstract

The invention relates to a roller stepless speed change self-adaptive control method and system and a harvester thereof. Self-inspection is carried out on a belt to determine to enter a self-adaptivecontrol mode, and if the self-adaptive control mode is entered, the first rotating speed of a roller is automatically obtained. According to a first comparison result obtained by comparing the first rotating speed with the first theoretical rotating speed, the driving speed of the harvester is controlled according to the first comparison result so as to ensure the feeding amount of the roller, sothat the roller is maintained within an optimal rotating speed range, harvesting can be continuously carried out, self-adaptive adjustment is realized, and the labor intensity of a driver is relievedto a certain extent; meanwhile, manual intervention of the driver in the harvesting process is reduced, better man-machine interaction is achieved, and the intelligent degree of harvesting operation is improved; and meanwhile, the driver can better know the abrasion degree of the belt to a certain extent, and subsequent maintenance and management are facilitated.

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 ...
