Background technology:
Along with the fast development that road traffic construction and mineral products are built, unit in charge of construction needs to excavate various tunnel, and, tunnel is more and more higher, the supporting of tunnel top and reinforcing become difficult point and the emphasis of construction, particularly not easily smear concrete fast, adopt and manually smear that concrete is taken a lot of work, time-consuming, efficiency is low. For this kind of situation, people develop some shotcrete machines, the cement according to a certain ratio being stirred, sand, stone compound are prepared burden by rotor, delivers to shower nozzle with pressurized air by carrier pipe, add water again and it is sprayed onto in construction surface, it is achieved the object of concrete strengthening fast. Being provided with opening for feed, inlet mouth and discharge port on the rotor body of existing shotcrete machine, compound is filled in little material cup by opening for feed, and when the little material cup that compound is housed turns to inlet mouth, compound is blown out by high pressure gas, and little material cup is rotated further.
The core position of shotcrete machine is rotor body, and the key position of rotor body be three friction blocks, namely the rubber seal of air inlet end friction block, discharge end rubber seal friction block, opening for feed rubber seal friction block. We just say one theory " opening for feed rubber seal friction block " specially now, concrete ejection rotor body is provided with some opening for feeds altogether, owing to the cross section of these opening for feeds is bigger, so opening for feed rubber seal friction block just is easy to occur partially grind phenomenon in production, what namely have that the position of mouth grinds is just fast, and that the position there be not mouth is ground is just slow, so very fast opening for feed rubber seal friction block will be ground with one ditch to be come, thus causes opening for feed rubber seal friction block to run gas impact and produce.
Practical novel content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that a kind of structure is simple, easy to use, voltage regulation result is good and the concrete ejection machine inlet capable rubber seal of prolongs life friction block eccentric abrasion prevention device.
The technical solution of the utility model is:
A kind of concrete ejection machine inlet capable rubber seal friction block eccentric abrasion prevention device, containing sealing socket and seal friction block, the two is set in together, described sealing block is three, being two side seal blocks and a middle part sealing block respectively, three described sealing blocks are respectively arranged with pressure mechanism, and, the width of described middle part sealing block mates mutually with the width of rotor body upper feeding mouth, and the width of the described side seal block of both sides and the width of rotor body upper feeding mouth both sides adapt.
Described pressure mechanism comprises anchor, top pressure screw rod and nut, described anchor is fixed on described sealing socket, described nut is fixed on described anchor, and the inner of described top pressure screw rod is connected with described sealing block activity formula, and outer end and the described nut of described top pressure screw rod screw fixing.
Described pressure mechanism comprises anchor, top pressure screw rod, pressing plate and nut, described anchor is fixed on described sealing socket, described top pressure screw rod runs through described anchor, and, the inner of described top pressure screw rod is connected with described sealing block activity formula, outer end and the described nut of described top pressure screw rod screw fixing, described top pressure screw rod is set with pressing plate, is provided with spring between described pressing plate and anchor.
