Described shrouding is connected with the tube wall of changeover portion along the two ends of changeover portion circumferencial direction respectively through hinge and bolt.
The described angle between entrance linkage section and changeover portion is 90 ° ~ 180 °.
Described wear-resistant liner is polymer composite.
Beneficial effects of the present invention:
1, the mill feeding connecting tube of the present invention, rational in infrastructure, with low cost, easy to use.The bottom of charging connecting tube is provided with wear-resistant liner, adds the wearability that charging connecting tube is overall, slow down the material impact for charging connecting tube, extends the service life that charging connecting tube is overall.Simultaneously, adopt, between wear-resistant liner and the metal shell of connecting tube in charging connecting tube, the mode removably connected, can directly open the shrouding arranged on changeover portion after wear-resistant liner consumption wear-resistant liner is replaced, repair time and device cost are saved, improve the production efficiency of grinding machine, be conducive to the pollution of waste and the environment avoiding discarded connecting tube to cause.
2, the mill feeding connecting tube of the present invention, between the end face of entrance linkage section and grinding machine feeding mouth, the setting of sealing ring improves the sealing effectiveness of grinding machine, it is to avoid the generation of mill feeding mouth material leakage phenomenon, meanwhile, also extends the service life of grinding machine.
3, the mill feeding connecting tube of the present invention, a plurality of reinforcement axially disposed on entrance linkage section medial wall further enhancing wearability and the mechanical strength of charging connecting tube entrance linkage section, extend the service life of charging connecting tube, grinding machine can continuous charging, be conducive to the continuous industrial production of grinding machine to operate.
4, the mill feeding connecting tube of the present invention, the setting of changeover portion upper sealing plate, it is possible to when there are the faults such as abrasion or blocking in charging connecting tube, facilitates the replacing within charging connecting tube and investigation maintenance.
5, the mill feeding connecting tube of the present invention, the setting of one end adjuvant inlet pipe that entrance linkage section is connected with changeover portion, some can be facilitated need to increase the production line of adjuvant for the increase of adjuvant and Homogeneous phase mixing, washing away and the safeguarding when setting of entrance linkage section end adjuvant inlet pipe can be also used for the blocking of charging connecting tube.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
A kind of mill feeding bridge piece, including for connecting the changeover portion 1 of charging gear and for connecting the entrance linkage section 2 of grinding machine feeding mouth, described changeover portion 1 and entrance linkage section 2 are structure as a whole, and changeover portion 1 is in a certain angle with entrance linkage section 2, the top tube wall of described changeover portion 1 is provided with a unlimited liner and lays mouth, liner is laid mouth place and is provided with the shrouding 3 removably connected, the lower inner wall face of described connecting tube is provided with wear-resistant liner 5, it is connected by bolt 6 between this wear-resistant liner 5 and tube wall of connecting tube, and one end that bolt 6 is connected with wear-resistant liner 5 is additionally provided with wear-resisting catch 601.
One end that described entrance linkage section 2 is connected with changeover portion 1 be additionally provided with one with the adjuvant inlet pipe 4 being connected inside connecting tube.
