Abstract
The invention discloses a concrete mixer mixing shaft sealing mechanism which comprises a mixing shaft, the mixing shaft is inserted into a hopper, and a sealing pedestal preventing concrete mortar from seeping along the mixing shaft is arranged on the outer side of the mixing shaft. The concrete mixer mixing shaft sealing mechanism is characterized in that a scraper seal is arranged between the sealing pedestal and the hopper, a seal ring is arranged at one end, far from the hopper, of the sealing pedestal, a water-stop belt used for containing water is arranged between the scraper seal and the seal ring, and the water-stop belt is connected with a water tank through a liquid inlet formed in the sealing pedestal. According to the technical scheme, the concrete mixer mixing shaft sealing mechanism can effectively prevent the concrete mortar from seeping and damaging equipment, carry out effective sealing on the concrete mortar, prolong the service life of a seal structure, reduce maintenance frequency and reduce maintenance cost and use cost.
Description
Technical field
The present invention relates to a kind of concrete mixer, relate in particular to concrete mixer stirring shaft sealing mechanism.
Background technique
Concrete mixer be a kind of in construction widely used equipment.Available coagulation soil stirrer drives an end by stirring motor and stretches into stirring shaft in the hopper, because this equipment is when work, concrete directly contacts with stirring shaft, in order to prevent that concrete from oozing out hopper along stirring shaft, usually prevent from oozing out by the solid dust ring, because concrete has certain pressure in hopper, mortar can infiltrate from the micro gap of dust ring and stirring shaft junction in the sealing mechanism during stirrer work, sealing mechanism is worn and torn, dust ring is very fast inefficacy usually, the spillage phenomenon appears in stirrer, and concrete mixer is broken down, and has increased maintenance cost and user cost.
Summary of the invention
The objective of the invention is the deficiency at the prior art existence, provide a kind of concrete mortar seepage that effectively prevents equipment to be caused the concrete mixer stirring shaft sealing mechanism of damage, this device effectively seals concrete mortar, improved the working life of sealing configuration, reduce maintenance frequency, reduced maintenance cost and user cost.
For achieving the above object, a kind of concrete mixer stirring shaft of the present invention sealing mechanism adopts following technological scheme:
A kind of concrete mixer stirring shaft sealing mechanism, comprise stirring shaft, stirring shaft inserts hopper, arranged outside at stirring shaft prevents that concrete mortar from oozing out sealing seat along stirring shaft, be provided with dust ring between described sealing seat and the hopper, be provided with seal ring at sealing seat away from an end of hopper, be provided with between dust ring and seal ring be used to the water-stop band of depositing water, described water-stop band is connected with water tank by the liquid entering hole that is arranged on the sealing seat.
The sealing seat end face of described dust ring one side is provided with and is no less than radially tank of twice, and each road radially tank communicates with water tank by liquid entering hole.
Described radially tank is connected with liquid entering hole by spiral channel, and the Hand of spiral of described spiral channel is pointed to hopper along the sense of rotation of stirring shaft.
The bottom of described sealing seat is provided with cock of water drain.
Be provided with the second road seal ring at sealing seat away from the seal ring side of an end of hopper.
Described water tank is provided with pressurization device.
Compare with background technique, concrete mixer stirring shaft sealing mechanism of the present invention, between dust ring and seal ring, be provided be used to the water-stop band of depositing water, described water-stop band is connected with water tank by the liquid entering hole that arranges on the sealing seat, the pressure of water is higher than the pressure of hopper inner concrete in the water-stop band, the micro-gap that utilizes sealing place to exist, and water oozes out to the hopper direction, stop oozing out of concrete mortar, prolonged the life-span of sealing mechanism; Radially tank can wash dust ring mortar, the wearing and tearing that slowed down dust ring improve its working life; Spiral channel can oppositely push current to hopper under the stirring shaft turning effort, impact mortar and flow to hopper; Even there is mortar to infiltrate, the bottom of opening sealing seat utilizes the water of water tank to clean sealing seat, and mortar is cleaned up, and recovers the cleaning in the sealing seat, reduces sealing seat because the wearing and tearing that the intrusion of mortar brings; When if the long-term shutdown of equipment is not used, bleed off by the water of cock of water drain with the hydraulic pressure sealing strip, prevent that ponding from getting rusty; The present invention has controlled the problem of stirrer stirring shaft spillage by water-stop, has very strong practicability, can be extensive use of on the stirrer of construction.
