On madial wall below described entrance linkage section is positioned at, be provided with vertically many reinforcements.
Described shrouding is connected with the tube wall of changeover portion with bolt by hinge respectively along the two ends of changeover portion circumferencial direction.
Angle between described entrance linkage section and changeover portion is 90 ° ~ 180 °.
Described wear-resistant liner is polymer composite.
Beneficial effect of the present invention:
1, mill feeding tube connector of the present invention, rational in infrastructure, with low cost, easy to use.The bottom of charging tube connector is provided with wear-resistant liner, has increased the wearability of charging tube connector entirety, has slowed down the impact of material for charging tube connector, has extended the service life of charging tube connector entirety.Simultaneously, between wear-resistant liner in charging tube connector and the metal shell of tube connector, adopt the mode removably connecting, after wear-resistant liner consumption, can directly open the shrouding arranging on changeover portion changes wear-resistant liner, repair time and device cost are saved, improve the production efficiency of grinding machine, be conducive to avoid waste that discarded tube connector causes and the pollution of environment.
2, mill feeding tube connector of the present invention, between entrance linkage section and the end face of grinding machine feeding mouth sealing ring the sealing effectiveness that has improved grinding machine is set, avoided mill feeding mouth to leak the generation of material phenomenon, meanwhile, also extended the service life of grinding machine.
3, mill feeding tube connector of the present invention, many reinforcements that arrange vertically on entrance linkage section madial wall have further strengthened wearability and the mechanical strength of charging tube connector entrance linkage section, extend the service life of charging tube connector, grinding machine can continuous charging, is conducive to the continuous industrial production running of grinding machine.
4, mill feeding tube connector of the present invention, the setting of changeover portion upper sealing plate, can there is the faults such as wearing and tearing or obstruction at charging tube connector time, facilitates replacing and the investigation maintenance of charging tube connector inside.
5, mill feeding tube connector of the present invention, the setting of one end auxiliary material inlet pipe that entrance linkage section is connected with changeover portion, can facilitate some production lines that need increase auxiliary material for the increase of auxiliary material and evenly mix, the arranging of entrance linkage section end auxiliary material inlet pipe can also be used for charging tube connector washing away and safeguarding while stopping up.
