Abstract
The utility model discloses a kind of wet-spraying machine output shaft seal structures, the steel liner plate of output shaft end is fixed on by fastening bolt, it further include being arranged in rotor block, sealing shroud between main shaft key and steel liner plate, zero type sealing ring I is provided on the inner peripheral surface of the sealing shroud, zero type sealing ring II is provided on outer circumference surface, copper packing is provided between the fastening bolt and steel liner plate, the rotor block is matched with the main shaft keyway on main shaft by main shaft key and is connect with main shaft, the rotor block processes zero type step by vehicle circle with main shaft key top inner side, the sealing is set in zero type step.The utility model has prevented main shaft into the channel of slurry, reduces after-sales service expense, reduces production delay, effect highly significant caused by shutdown.
Description
Technical field
The utility model relates to concrete spraying machine equipment fields, export sealing knot more particularly to a kind of wet-spraying machine
Structure.
Background technique
HSP600-700 wet-spraying machine, is the main product of my company's many years, but have a problem long-standing problem this production
The service performance of product, that is, spillage problem are transported because its core is the piston motion by rotating to realize
Spillage at dynamic part can not be eradicated thoroughly, in actual operation because concrete mortar leakage is in the fuel tank of machinery, cause
Running gear inordinate wear so as to cause rotor block damage, and repairs particularly troublesome.
As shown in Fig. 2, its design for exporting sealing of the wet-spraying machine of home and abroad is all made of end part seal, in steel liner plate 1
Top and main shaft 3 between using copper packing 8 seal, under steel liner plate with the sealing of rotor block 2 using end O-ring 9 seal, but reality
Border situation is all bad, with the abrasion of steel liner plate, needs the clamping bar for timely tightening rotary body to guarantee the stress of steel liner plate
Uniformly, but the fact is that the stress of steel liner plate is difficult to be verified always to reach stress balance, therefore steel liner plate will agitate inclination, break
The seal face of bad end O-ring 9 cooperates, to cause cement slurry gap and main shaft 3 four between steel liner plate 1 and rotor block 2
Peripheral wall and main shaft keyway flow into the oil sump of lower part.
Utility model content
Place in view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of wet-spraying machine output shaft is close
Seal structure changes the leakage problem of existing sealing structure.
The purpose of this utility model is achieved through the following technical solutions:
A kind of wet-spraying machine output shaft seal structure, the steel liner plate of output shaft end is fixed on by fastening bolt, further includes setting
The sealing shroud between rotor block, main shaft key and steel liner plate is set, zero type sealing ring is provided on the inner peripheral surface of the sealing shroud
I, zero type sealing ring II is provided on outer circumference surface.
In order to which the utility model is better achieved, copper packing is provided between the fastening bolt and steel liner plate.
Further, the rotor block is matched with the main shaft keyway on main shaft by main shaft key and is connect with main shaft.
Preferably, the rotor block and main shaft key top inner side process zero type step, the sealing shroud by vehicle circle
It is arranged in zero type step.
The utility model compared with the prior art, have the following advantages that and the utility model has the advantages that
The utility model has prevented main shaft into the channel of slurry, reduces after-sales service expense, reduces raw caused by shutdown
Produce delay, effect highly significant.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sealed structural schematic diagram of the prior art.
Specific embodiment
The utility model is described in further detail below with reference to embodiment, but the embodiments of the present invention is not
It is limited to this.
Embodiment
A kind of wet-spraying machine output shaft seal structure is fixed on the steel liner plate 1 of output shaft end by fastening bolt 7, further includes
Sealing shroud 4 between rotor block 2, main shaft key 31 and steel liner plate 1 is set, is provided with zero on the inner peripheral surface of the sealing shroud 4
Zero type sealing ring II6 is provided on type sealing ring I5, outer circumference surface.
In order to which the utility model is better achieved, copper packing 8 is provided between the fastening bolt 7 and steel liner plate 1.
Further, the rotor block 2 is matched with the main shaft keyway on main shaft 3 by main shaft key 31 and is connect with main shaft 3.
Preferably, the rotor block 2 processes zero type step 10 by vehicle circle with 31 top inner side of main shaft key, it is described close
Big envelope 4 is arranged in zero type step 10.
In conclusion description through this embodiment, can make those skilled in the art's better implementation this programme.
