The lower parts of the left side plate and the right side plate assembled by the interface baffle plate extend to the position of the shell of the rear lifting device, which is close to the lower arc end.
The arc cover is welded and fixed on the outer part of the lower arc end of the shell of the rear lifting device through screws. The arc cover welding comprises a semicircular arc cover body 4.1, the shape of the arc cover body is matched with the shape of the lower arc end of the shell of the rear lifting device, and the arc cover body can be in surface contact with the lower arc end of the shell of the rear lifting device. Two groups of hinge seats 4.2 are welded at the position of the arc cover body, which is close to the upper end, each group of hinge seats consists of two hinge vertical lugs which are arranged in parallel left and right, and coaxial rotating shaft mounting holes are formed in the two hinge vertical lugs. The arc cover weld is used for realizing the sealing of the lower end of the feed inlet of the rear lifting device on one hand and the installation of the rotary baffle plate assembly on the other hand.
