Abstract
The utility model relates to an automatic resilient revolving door. The utility model is applied to a high-concentration grout transfer pump for fitting with a hose pipe. In a conventional transfer pump, the sliding friction between the roller and the hose pipe is large, so the service life of the hose pipe is short due to heavy stress. The automatic resilient revolving door comprises a revolving door 1 and a spring door spindle device 2 fixed at one side of the revolving door 1. The spring door spindle device 2 comprises an upper pipe 3 connected with a revolving pipe 4 via an upper oil shaft 6; the revolving pipe 4 is connected with a lower pipe 5 via a lower oil shaft 7; a torsion spring 8 is arranged in the revolving pipe 4, one end of the torsion spring 8 is connected with the upper oil shaft 6 and the other end is connected with a spring limiting frusta. The utility model is applied in an artificial soil seeding machine.
