A guide frame is symmetrically arranged outside the boom, the bottom of the guide frame is fixed to the portal, and the head of the lever passes through the guide frame.

[0009] As a further improvement of the above technical scheme:

[0010] The flange has an integrated structure.

[0011] The middle part of the flange adopts a square structure, and the outer ends of the square structure extend outwardly with support rods, which are locked with the push rod through fasteners.

[0012] The push rod adopts a strip-shaped structure.

[0013] The guide frame is symmetrically arranged with two.

[0014] The structure of the single guide frame is that a slope frame is fixed on a portal, and a notch is arranged on the top surface of the slope frame, and the push rod is penetrated through the notch.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model discloses compact structure, reasonable, convenient operation, through the mutual cooperation of swivel support, flange, push rod, guide frame and other components, the large angle rotary work of ship loader can be conveniently realized, and the phenomenon that the soft cover is twisted and stuck is not caused, and compensation is carried out through the action of the swivel support, thereby the continuity, practicality and reliability required for the dust cover of the ship loader belt conveyor system are achieved.

[0025] The specific implementation manner of the utility model will be described below in combination with the drawings.

[0026] For example, Figures 1-6As shown, the ship loader rotary interface closing device of the embodiment comprises a portal 8, the portal 8 is provided with an arm support 7 of the ship loader, the top surface of the arm support 7 is provided with a receiving hopper 5; further comprising a flange 3 which is spaced apart from the receiving hopper 5, the middle part of the flange 3 is provided with a circular hole, the upper part of the flange 3 is provided with a rotary support 2, the inner ring of the rotary support 2 is connected with a feeding hopper 1, the feeding hopper 1 is communicated with the receiving hopper 5 through the circular hole of the flange 3, a soft cover 4 is arranged between the flange 3 and the receiving hopper 5, the outer ring of the rotary support 2 is fixed with the flange 3 through fasteners, and the outer end of the flange 3 is provided with a push rod 9 through fasteners; further comprising a guide frame 6 which is symmetrically arranged outside the arm support 7, the bottom of the guide frame 6 is fixed with the portal 8, and the head of the push rod 9 penetrates through the guide frame 6.

[0027] The flange 3 is in an integral structure.

[0028] The middle part of the flange 3 adopts a square structure, and the two outer ends of the square structure extend outwardly and are provided with supporting rods, and the supporting rods are locked with the push rod 9 through fasteners.

[0029] The push rod 9 adopts an elongated structure.

[0030] The guide frame 6 is symmetrically arranged with two.

[0031] The structure of a single guide frame 6 is as follows: comprising an inclined frame 602 which is fixed on the portal 8, the top surface of the inclined frame 602 is provided with a notch 601, and the push rod 9 penetrates through the notch 601.

[0032] As shown in Figure 1 and Figure 2 , the rotary center 0 is the vertical center line of the portal 8 and the arm support 7, and the rotary center 0 rotates during rotation.

[0033] The specific structure and functions of the ship loader rotary interface closing device are as follows:

[0034] Mainly comprising a feeding hopper 1, a rotary support 2, a flange 3, a push rod 9, a guide frame 6, a soft cover 4, an arm support 7, a portal 8 and the like.
