Permanent magnet variable frequency driving device for bulk cargo belt line

Abstract

The utility model relates to the field of belt line especially relates to permanent magnet variable frequency drive device for bulk cargo belt line, including base, one side fixedly connected with drive motor of base, drive roll is connected in the base rotationally, it is fixedly connected between drive roll and the output of drive motor, the utility model has the following beneficial effect: drive motor, drive roll and belt cooperate operation constitute the core power system of bulk cargo transportation, can complete bulk cargo conveying operation. In this process, the abutment keeps contact with the drive roll surface all the time, when the drive roll appears abrasion because of long -term use, the reset spring will push the abutment along the in -place plate sliding, and then drive the indicating piece synchronous action, and the staff can intuitively and accurately judge the abrasion degree of drive roll through the corresponding relation of observation indicating piece and scale mark, thereby timely determine whether the drive roll needs maintenance or replacement, effectively avoid the equipment failure caused by drive roll abrasion, guarantee bulk cargo transportation device continues stable operation.
