Detailed Description
The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.
Examples are given. A special follow rest for processing a three-screw asphalt pump rotor is shown in figure 1 and comprises a follow rest 1, wherein positioning surfaces 101 are arranged on the top and the side of the follow rest 1, a positioning block 2 is connected to the positioning surfaces 101, and a spring 3 connected with the follow rest 1 is arranged at the end part of the positioning block 2; the top of the follow rest 1 is provided with a support frame 4, and the support frame 4 is rotatably connected with a scrap blocking plate 5.
