Abstract
The utility model 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 utility model relates to a kind of concrete mixer, relates in particular to concrete mixer stirring shaft sealing mechanism.
Background technique
Concrete mixer be a kind of in construction widely used equipment.Existing concrete mixer drives one end to stretch into the stirring shaft in hopper by stirring motor, because this equipment is when working, concrete directly contacts with stirring shaft, in order to prevent that concrete from oozing out hopper along stirring shaft, conventionally by solid dust ring, prevent from oozing out, because concrete has certain pressure in hopper, during stirrer work, mortar can infiltrate from the micro gap of dust ring and stirring shaft junction in sealing mechanism, sealing mechanism is worn and torn, dust ring lost efficacy conventionally very soon, there is spillage phenomenon in stirrer, concrete mixer is broken down, maintenance cost and user cost have been increased.
Summary of the invention
The purpose of this utility model is the deficiency existing for prior art, provide a kind of and effectively prevent that concrete mortar seepage from causing the concrete mixer stirring shaft sealing mechanism of damage to equipment, this device carries out effective sealing to 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 utility model 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, between described sealing seat and hopper, be provided with dust ring, at sealing seat, away from one end of hopper, be provided with seal ring, be provided with for depositing the water-stop band of water between dust ring and seal ring, described water-stop band is connected with water tank by the liquid entering hole being arranged on sealing seat.
On the sealing seat end face of described dust ring one side, be provided with and be no less than radially tank of twice, 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.
At sealing seat, away from the seal ring side of one end of hopper, be provided with second seal ring.
Described water tank is provided with pressurization device.
Compare with background technique, concrete mixer stirring shaft sealing mechanism of the present utility model, between dust ring and seal ring, be provided with for depositing the water-stop band of water, described water-stop band is connected with water tank by the liquid entering hole arranging on sealing seat, in water-stop band, the pressure of water, higher than the pressure of hopper inner concrete, utilizes the micro-gap of sealing place existence, and water oozes out to hopper direction, stop oozing out of concrete mortar, extended the life-span of sealing mechanism; Radially tank can rinse dust ring mortar, slowed down the wearing and tearing of dust ring, improve its working life; Spiral channel can, to hopper reverse extrusion current under stirring shaft turning effort, impact mortar and flow to hopper; Even if 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 clean in sealing seat, reduces the wearing and tearing that sealing seat brings due to the intrusion of mortar; If when the long-term shutdown of equipment is not used, the water of water-pressure sealed band is bled off by cock of water drain, prevent that ponding from getting rusty; The utility model has been controlled the problem of stirring shaft of stirring machine spillage by water-stop, have very strong practicability, can be widely used on the stirrer of construction.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model concrete mixer stirring shaft sealing mechanism.
Fig. 2 is the partial enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these mode of executions and only for the utility model is described, be not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As depicted in figs. 1 and 2, the utility model discloses a kind of concrete mixer stirring shaft sealing mechanism.This concrete mixer stirring shaft sealing mechanism, comprise stirring shaft 1, stirring shaft 1 inserts hopper 2, stirring shaft 2 is connected with stirring motor 3, arranged outside at stirring shaft prevents that concrete mortar from oozing out sealing seat 4 along stirring shaft, sealing seat 4 is fixedly connected with hopper 2, between sealing seat and hopper, be provided with dust ring 5, at sealing seat, away from the inside, one end of hopper, be provided with seal ring 6, between dust ring and seal ring, be provided with for depositing the water-stop band 7 of water, described water-stop band is connected with water tank 8 by the liquid entering hole 41 being arranged on sealing seat, water tank is provided with pressurization device, or thereby the water extraction that water tank is arranged in higher position feedwater sealing strip supplies larger pressure, higher pressure can be better by hydraulic pressure to hopper one side, rinse the mortar in seal clearance, on the sealing seat end face of described dust ring one side, be provided with and be no less than radially tank 42 of twice, these radially tank be distributed on sealing seat end face, the current that can make are more even, described radially tank is connected with liquid entering hole by spiral channel 43, the Hand of spiral of described spiral channel is pointed to hopper along the sense of rotation of stirring shaft, under the rotation of stirring shaft, water in water channel pushes to hopper direction, better rinse the mortar in gap, in the bottom of sealing seat, be provided with cock of water drain 44, cock of water drain can be discharged the mortar entering in water-stop band, also can in the situation that not using concrete extra flight, emit inner liquid, prevent that ponding from getting rusty, at sealing seat, away from the seal ring side of one end of hopper, be provided with second seal ring 6, seepage in the anti-waterstop sealing band of double sealing.
