Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below. It should be understood, however, that the description herein of specific embodiments is for purposes of illustration only and is not intended to limit the scope of the present disclosure.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention.

As shown in fig. 1, 2 and 3, a milling wheel rotary supporting device capable of being rapidly disassembled and replaced comprises an outer cylinder body 1, a rotary drum 2, a connecting shaft 3, a bearing 4, a bearing seat 5, a right side plate 7 and a connecting disc 8;

the outer circumference of the outer barrel body 1 is regularly provided with a plurality of cutters 6, the inner side of the outer barrel body 1 is provided with a roller 2, the roller 2 is fixedly connected with a speed reducer, a stepped structure is adopted between the contact surfaces of the roller 2 and the outer barrel body 1 to support in a matching way, and the roller 2 and the right side of the outer barrel body 1 are fixed by bolts, so that the movement and power are transmitted to the roller 2 from the speed reducer and then transmitted to the outer barrel body 1 from the roller 2, and finally the cutters 6 on the outer barrel body 1 are driven to realize synchronous milling operation;

one end of the connecting shaft 3 is connected with the roller 2, if the connecting shaft and the roller are connected through bolts, the connecting shaft and the roller move synchronously, the other end of the connecting shaft 3 is connected with the bearing 4, the bearing 4 is supported on the bearing seat 5, the outer circular surface of the bearing seat 5 is matched with the inner circular surface of the connecting disc 8, and the connecting disc 8 is installed on the right side plate 7 of the outer frame through the fastening bolt 9 and cannot rotate along with milling operation;
