Abstract

The invention relates to the technical field of construction machinery, in particular to a hopper assembly and a concrete pump truck. The hopper assembly includes: a hopper, a hopper cover and a locking mechanism. The locking mechanism includes a stopper, a first locking piece and a second locking piece. The stopper and the first locking piece are respectively arranged in the hopper cover and the hopper. On one and the other, the first locking member is rotatable between the locking position and the unlocking position, and the second locking member is movably connected to the first locking member; wherein the hopper assembly has a locked state and In the unlocked state, in the locked state, the hopper cover is closed, the first locking member rotates to the locking position, and is combined with the stopper, the second locking member moves to the first position relative to the first locking member, and the first locking member is moved to the first position. A locking piece is locked with the stopper; in the unlocked state, the second locking piece is disengaged from the stopping piece, and the first locking piece is rotated to the unlocking position and disengaged from the stopping piece. This reduces the risk of the hopper cover shaking due to road bumps etc.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a hopper assembly and a concrete pump truck. Background technique [0002] In a concrete pump truck, a hopper cover is generally provided on the hopper, and the hopper cover can be opened and closed to connect with the hopper to block the concrete in the hopper and prevent the concrete from overflowing or splashing. [0003] During driving conditions, the hopper cover is generally closed to prevent overflow problems. However, because the road conditions of the concrete pump truck are usually poor and the road surface is bumpy, the hopper cover is easy to shake up and down, which affects the material covering effect, and the hopper cover is easily damaged due to the up and down shaking, which affects the service life. SUMMARY OF THE INVENTION [0004] A technical problem to be solved by the present invention is to reduce the risk of shaking of the hopper cover. ...
