Abstract

The invention relates to a grain processing machine, in particular to a driving device with double variable frequency motors of a rubber roll rice huller. The driving device comprises the motors and a coupler, and is characterized by further comprising frequency converters, a touch control screen and a programmable controller, wherein the motors are the variable frequency motors, the touch control screen is connected with the programmable controller, the programmable controller is also connected with the two frequency converters, a guide line is connected between the two frequency converters which are respectively connected with the two variable frequency motors, and main shafts of the two variable frequency motors are connected with a high-speed roll and a low-speed roll through the coupler respectively. The driving device not only is simple in structure, novel, low in noise and convenient to operate, but also maintains the linear speed of the high-speed roll and the linear speed of the low-speed roll and the linear speed difference stable, and enables the rice huller to operate stably and reliably.

Description

[0001] technical field [0002] The invention relates to a grain processing machine, in particular to a double frequency conversion motor driving device of a rubber roller huller. Background technique [0003] The rubber roller husker is an important rice processing equipment. The main working part is to place the two rollers in the same horizontal plane or with a slight height difference. One roller is fixed in position and the other roller can be moved so that the two The rolling distance between the rollers is adjustable. When working, the working principle of the differential pair of rollers is adopted, and the two rollers are rotated in different directions and at different speeds. The paddy is extruded by the two rollers and rubbed and torn by the speed difference between the two rollers, and the shelling is achieved. Purpose. [0004] According to the working principle of the differential transmission of the rubber roller husker, in terms of drive and transmission m...
