Description

Grab bucket mechanism

Technical Field

The utility model relates to the technical field of white spirit brewing, in particular to a grab bucket mechanism.

Background

In the brewing process, after fermentation of the fermented grains in the pit is completed, the fermented grains need to be moved out of the pit, which is called a pit discharging process. The traditional pit discharging process is manual operation, namely shoveling fermented grains into a bin by using tools such as shovels and the like, and carrying the bin filled with the fermented grains by a travelling crane. The manual operation is low in production efficiency and high in labor intensity, and due to the fact that the alcohol concentration in the cellar is high and oxygen is thin, safety accidents of suffocation of workers easily occur. At present, a grab bucket with high mechanization degree is often adopted to grab fermented grains in a pit pool to complete a pit discharging process, so that the production efficiency is improved, and the labor intensity of workers is reduced.

The structure of a prior art grapple is shown in fig. 1. Referring to fig. 1, the conventional grab bucket includes a fixed plate 101, a connecting plate 102 disposed below the fixed plate 101, a cylinder 103 installed between the fixed plate 101 and the connecting plate 102, and a grab bucket body 104 disposed at both sides of the connecting plate 102 and hinged to the connecting plate 102; each grapple body 104 is hinged to the fixed plate 101 by a connecting rod 105.

When the grapple in fig. 1 is in an open state, when the fermented grains are to be grabbed, the cylinder 103 is started, the piston rod of the cylinder 103 is contracted to drive the connecting plate 102 to move upwards, and then the two grapple bodies 104 are closed to grab the fermented grains. However, when the grab bucket grabs the fermented grains, the fermented grains are easily stuck on the piston rod of the cylinder 103, so that the blockage of the piston rod is caused, the piston rod is corroded in severe cases, and the service life of the cylinder is shortened.
