Of course, the driving mechanism here may also be a hydraulic cylinder, and is not limited in particular here.

As shown in fig. 2 and 3, a shielding member 24 is disposed above the bottom frame 21 for shielding the top of the material frame 01, and the shielding member 24 is used for shielding the upper end of the material frame 01 when the material frame 01 is turned over by the turning frame 2, so as to prevent the material frame 01 from turning over and sliding down along with the workpiece when the material frame 01 is turned over.

In this embodiment, the shielding member 24 can be a rod, two ends of the rod are respectively mounted on the side frames 22, and for convenience, the mounting plates 241 are respectively disposed at two ends of the shielding member 24.

In order to adapt to the material frames 01 with different heights, in the embodiment, the height of the shielding element 24 relative to the bottom frame 21 is adjustable, specifically:

referring to fig. 4 and 5, a plurality of first mounting holes 221 are formed in the two side frames 22 at intervals along the height direction of the side frames 22, second mounting holes 2411 for abutting against the first mounting holes 221 are formed in two ends of the shielding member 24, and specifically, the second mounting holes 2411 are formed in the mounting plates 241.

In this way, the shielding member 24 can be installed on the first installation hole 221 with a suitable height according to the height of the material frame 01 actually used, and during specific installation, the first installation hole 221 and the second installation hole 2411 are aligned, then the first installation hole 221 and the second installation hole 2411 are penetrated by bolts, nuts are screwed on the bolts for locking, and at this time, the shielding member 24 is installed completely.

In order to further adjust the installation height of the shielding member 24, in this embodiment, the first installation hole 221 is a kidney-shaped hole extending along the height direction of the side frame 22. Therefore, after the shielding member 24 is abutted to the corresponding first mounting hole 221, the height of the shielding member may be deviated, and at this time, fine adjustment can be performed along the first mounting hole 221 up and down along the first mounting hole 221, so that the height of the shielding member 24 is better matched with the height of the material frame 01.

Of course, in order to have a better locking effect on the shielding element 24, in this embodiment, as shown in fig. 4, two rows of the first mounting holes 221 are provided on the same side frame 22 in the horizontal direction, and similarly, two second mounting holes 2411 corresponding to the two rows of the first mounting holes 221 are provided on the same mounting plate 241, so that when the shielding element 24 is mounted, the mounting plate 241 can be butted through the two first mounting holes 221 at the same time, so as to improve the locking effect.

In order to improve the safety of the device during use, in this embodiment, the feeding tipping bucket further includes a protective net 4 and a protective door 5, and the protective net 4 is arranged on the frame 1 and located on two sides of the roll-over stand 2; the protection door 5 is located at the open side of the roll-over stand 2, and the protection door 5 can be opened or closed, specifically: the side end of the protective door 5 is hinged to the frame 1, and of course, the side end of the protective door 5 can also be hinged to one of the protective nets 4, so that the protective door 5 can rotate in the horizontal direction to open or close.

For convenience of illustration, the end of the protective door 5 opposite to the hinged end is a movable end, i.e. an end capable of freely rotating.

It should be noted that a latch (not shown in the drawings) may be provided on the side edge of the movable end of the protection door 5, and after the protection door 5 is closed, the latch is inserted to keep the protection door 5 in the closed state.

It should be noted that, in this embodiment, the protective door 5 may also be a mesh door, and when the material is loaded in the overturning manner, the protective door 5 may be closed, so that under the protection of the protective mesh 4 and the protective door 5, the device and the staff are isolated, thereby achieving a certain protection effect on the staff.

The protective door 5 may be a protective door that is opened/closed manually or an electric door, and is specifically selected according to actual needs.

As an alternative embodiment, in this embodiment, a limit switch (not shown in the figure) is disposed inside the movable end of the protection door 5, where the limit switch may be a proximity sensor or a proximity switch; when the protective door 5 is opened, the limit switch is not triggered, the driving mechanism does not act, specifically, the limit switch is connected with a controller, when the protective door 5 is in an opening state, the limit switch is separated from the rack 1 to be contacted with the rack 1, so that the limit switch is not triggered, the controller can control the driving mechanism to be in a locking state, namely, the driving mechanism is kept in an out-of-operation state, and thus, the driving mechanism is controlled to drive the roll-over stand 2 to act under the state that the protective door 5 is opened by a worker. When the protective door 5 is closed, the limit switch is in contact with the rack 1 at the moment, the limit switch is in a trigger state, the controller releases the locking state of the driving mechanism at the moment, and the driving mechanism can be freely controlled to act.
