[0013] Preferably, guide wheels are provided in the mounting shell, and the guide wheels are clamped to the upper and lower sides of the guide rail.

[0014] Through this solution, the guide wheel can stabilize the movement of the bucket claw and avoid shaking; it can also support the mounting shell, reduce the radial pressure of the hydraulic motor drive shaft, and help to further improve the service life.

[0015] Preferably, the side of the dial head facing the support column is an arc-shaped guide surface, and the side opposite to the guide surface is a flat dial surface.

[0016] Through this solution, the guide surface can play a guiding role when returning, avoiding reverse driving of the bucket and overturning; the flat shifting surface pushes the bucket to flip.

[0017] Preferably, a fixing rod is provided on the shifting head, and the fixing rod is driven by a driving cylinder and can be extended to the shifting surface to clamp the side wall of the truck bucket.

The guide rail 200 is semicircular and is placed directly above the track; a bucket claw 300 is slidably connected to the guide rail 200, and the bucket claw 300 is driven by a hydraulic motor to move along the guide rail 200.

[0028] Through this solution of the present embodiment, the support column 100 is fixed to one side of the track, and the bucket is flipped by the arc movement of the bucket claw 300. The use of a hydraulic motor can eliminate the influence of dust, which helps to improve the service life while ensuring the tipping effect.

[0029] The support column 100 is fixed to one side of the vehicle track and fixed by expansion bolts, etc.; a support frame can be set on the other side of the guide rail 200, which not only plays a supporting role to prevent the support column 100 from tilting, but also the support frame will not interfere with the flipping of the vehicle bucket.
