Abstract
The invention discloses a kind of uniform friction device of concrete injection machine rubber friction block, it contains rotor block, multiple small powder chamber is provided with vertically in the middle of the periphery of described rotor block, there are charging aperture, air inlet port and discharging opening in each small powder chamber, described air inlet port and discharging opening are separately positioned on two end faces of described rotor block, described charging aperture is arranged on the periphery of described rotor block, on the periphery of the described rotor block of described charging aperture both sides and the end face of the described rotor block of air inlet port and discharging opening both sides be respectively arranged with boring.Described boring is blind hole or through hole.The present invention rationally arranges boring on the cylindrical surface and circular end face of rotor block, the friction on the both sides of rubber sealing block just increases the weight of relatively, the sealing surface of whole like this rubber sealing block will keep relative more smooth, thus ensures that its good sealing performance can not be destroyed.
Description
technical field:
The present invention relates to a kind of concrete spraying equipment, particularly relate to a kind of uniform friction device of concrete injection machine rubber friction block.
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 rapid application concrete, adopts and manually smears that concrete is taken a lot of work, time-consuming, efficiency is low.For this situation, people develop some concrete sprayers, the cement be according to a certain ratio stirred, sand, stone compound are prepared burden by rotor, delivers to shower nozzle with compressed air by conveying pipeline, add water again and be sprayed onto in working face, realize the object that rapid coagulation soil is reinforced.Existing concrete sprayer has three rubber sealing blocks, and these three rubber sealing blocks are called charging aperture sealing block, air inlet port sealing block and discharging opening sealing block respectively.In actual production, due to the special construction of the special construction of rotor and the sealing surface of sealing block, the rubber seal face of making can not be rubbed uniformly, but the weight of middle friction is a little, both sides friction lightly, the middle part of such rubber sealing block will soon be ground with one zanjon, thus forms deflation.
summary of the invention:
Technical problem to be solved by this invention is: overcome the deficiencies in the prior art, provide a kind of reasonable in design, friction uniformity is good and the uniform friction device of concrete injection machine rubber friction block of easily enforcement.
Technical scheme of the present invention is: a kind of uniform friction device of concrete injection machine rubber friction block, containing rotor block, multiple small powder chamber is provided with vertically in the middle of the periphery of described rotor block, there are charging aperture, air inlet port and discharging opening in each small powder chamber, described air inlet port and discharging opening are separately positioned on two end faces of described rotor block, described charging aperture is arranged on the periphery of described rotor block, on the periphery of the described rotor block of described charging aperture both sides and the end face of the described rotor block of air inlet port and discharging opening both sides be respectively arranged with boring.
Described boring is blind hole or through hole.Described boring is a row, or is more than two rows.
The invention has the beneficial effects as follows:
1, the present invention rationally arranges boring on the cylindrical surface and circular end face of rotor block, the friction on the both sides of rubber sealing block just increases the weight of relatively, the sealing surface of whole like this rubber sealing block will keep relative more smooth, thus ensures that its good sealing performance can not be destroyed.
2, the degree of depth of each boring of the present invention and diameter also moderate, position is moderate, also can bore through going, and also can not bore through going, but does not bore through going more proper, and the quantity of boring is moderate.
3, the cylindrical surface of rotor block of the present invention and circular end face being holed both can be a row, also can be two rows, can also be more rows, arrange as required, very convenient.
4, the present invention is reasonable in design, friction uniformity is good and easily implement, and it is applied widely, is easy to promotion and implementation, has good economic benefit.
accompanying drawing illustrates:
Fig. 1 is the structural representation of concrete sprayer;
Fig. 2 is the rear elevation of concrete sprayer shown in Fig. 1;
Fig. 3 is the left view of concrete sprayer shown in Fig. 1.
detailed description of the invention:
Embodiment: see Fig. 1-Fig. 3, in figure, 1-discharging opening sealing block, 2-playpipe, 3-discharging opening fixed mount, 4-hopper, 5-air inlet port fixed mount, 6-air inlet port sealing block, 7-air inlet pipe, 8-motor, 9-charging aperture sealing block, 10-charging aperture fixed mount, 11-holes, 12-rotor block.
Uniform friction device of concrete injection machine rubber friction block contains rotor block 12, multiple small powder chamber is provided with vertically in the middle of the periphery of rotor block 12, there are charging aperture, air inlet port and discharging opening in each small powder chamber, air inlet port and discharging opening are separately positioned on two end faces of rotor block 12, charging aperture is arranged on the periphery of rotor block, wherein: on the periphery of the rotor block 12 of charging aperture both sides and the end face of the rotor block 12 of air inlet port and discharging opening both sides be respectively arranged with boring 11.
Boring 11 is blind hole or through hole.Boring 11 is a row, or is more than two rows, determines as required, does not describe in detail one by one.
During work, motor 8 rotor driven body 12 rotates, charging aperture sealing block 9, air inlet port sealing block 6 contact with end face seal with the periphery of rotor block 12 respectively with discharging opening sealing block 1, due to hole 11 the degree of depth, direct sum position all moderate, thus the friction on the both sides of three rubber sealing blocks just increases the weight of relatively, the sealing surface of whole like this rubber sealing block will keep relative more smooth, thus ensures that its good sealing performance can not be destroyed.
The above, it is only preferred embodiment of the present invention, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
