A shaft end sealing structure and distribution machine

Abstract

Embodiments of the present invention provide a shaft end sealing structure and a distributing machine, which relate to the technical field of prefabricated component production equipment. The shaft end sealing structure provided by the embodiment of the present invention includes a slurry blocking structure and a slurry removing member. The slurry blocking structure is arranged between the hopper and the rotating shaft, and at the same time, the slurry blocking structure forms a sealing labyrinth which is communicated with the hopper, and the slurry in the hopper is preliminarily sealed through the sealing labyrinth. The de-slurry member is located on the outer side of the pulp-resisting structure, and the de-slurry member is movably cooperated with the rotating shaft. When part of the slurry moves outward along the axis of the rotating shaft through the sealing labyrinth, the relative movement between the de-sizing member and the rotating shaft is used to remove the slurry on the rotating shaft. The slurry is removed, thereby further ensuring the sealing performance, preventing the leakage of the slurry along the rotating shaft into the bearing and causing damage to the bearing, thereby helping to prolong the service life.

Description

technical field [0001] The invention relates to the technical field of prefabricated component production equipment, in particular to a shaft end sealing structure and a placing machine. Background technique [0002] During the production of concrete components, numerous equipments are needed to prepare concrete, such as placing machines. The placing machine is the terminal equipment for pumping concrete. Its function is to send the concrete conveyed by the conveyor to the mold of the component to be poured. It has a hopper to store the concrete slurry. A screw conveyor is arranged in the hopper. The rotation realizes the transportation of concrete slurry. [0003] Since the rotating shaft of the screw conveyor needs to be connected with the hopper, the slurry is easy to leak from the connection between the rotating shaft and the hopper, which not only causes waste of the slurry, but also the leaked slurry "climbs" into the bearing along the rotating shaft, which eventually...

AI Technical Summary

Problems solved by technology

[0003] Since the rotating shaft of the screw conveyor needs to be rotationally connected with the hopper, the slurry is likely to leak from the connection between the rotating shaft and the hopper, which not only causes a waste of slurry, but also the leaked slurry will "climb" into the bearing along the rotating shaft, eventually resulting in bearing damage
