Description

A kind of drum-type concrete injection device
Technical field
The utility model relates to building engineering construction field of mechanical technique, more specifically, being related to a kind of drum-type coagulation Native injection apparatus.
Background technique
Concrete is continuously conveyed along pipeline using compressed air for concrete sprayer, and is ejected into what construction surface got on It is mechanical.It is widely used in the construction of shotcrete operations such as underground engineering, hydroelectric project, well tunnel, culvert.It is mixed by concrete The water feeding method difference for closing material can be divided into dry type, wet type and fall between three kinds of tidal.Dry type refers to by a certain percentage Cement and aggregate, after mixing evenly, through compressed air be blown into nozzle and from pressure water tank pressure water mixing after spray;This Kind mode construction method is simple, and speed is fast, but dust is too big.Wet spraying machine is that the mud that will have been mixed passes through spraying machine Job site being delivered to high pressure gas or other way to be sprayed with high pressure gas again, this method injection is difficult, and problem is more, It is small using very inconvenient and jet power.And the tidal spraying machine to fall between is identical with the principle of dry spraying machine, It is used after only being stirred again with dry cement and accelerator into a small amount of clear water of mixture addition of spraying machine and dry spraying machine is identical Method injection, while also having biggish dust and generating, also be easy to cause machine itself and pipeline blockage.Therefore, for Upper defect needs reasonably to improve the prior art.
Utility model content
In order to overcome the technical drawbacks described above, the utility model provide it is a kind of do not block, the drum-type concrete spray of dust Injection device, to solve many deficiencies of the prior art.
To achieve the above object, the utility model uses following technical scheme:
A kind of drum-type concrete injection device, including bracket, are fixed with fixing axle between two brackets, two brackets it Between fixing axle on be set with roller, multiple vertebra shape slots are offered on roller;The outer sheath of the roller is equipped with ring shield, ring The top of shape shield offers feed inlet, and the bottom end of ring shield offers discharge port, and inlet port and outlet port are all and on roller The vertebra shape slot connection opened up;It is fixed with baffle on the outer roof of the ring shield, baffle is contacted with lever, and lever is fixed on two Between a bracket;One end of the roller is fixed with bull gear, and large ring gear meshing has pinion gear, and pinion gear is fixed on decelerating motor Output shaft on;Air inlet is offered in the fixing axle, the fixing axle bottom end in roller, air inlet is arranged in the outlet of air inlet The outlet in hole is connected to vertebra shape slot, and air inlet is connected to air pump by air induction hose;The discharge port is connected to mixed by discharge tube Expects pipe, spray head is equipped on mixing tube, and mixing tube is connected to cement stock tank by slurry pipeline, is equipped with mud on slurry pipeline Starch delivery pump.
Further, limited block is fixed in the fixing axle at the roller both ends.
Further, the mixing tube is connected to high-pressure water pipe by filler pipe, is equipped with valve on filler pipe.
The beneficial effects of the utility model are: course of injection does not generate dust, structure is simple, save the cost;Wet shotcrete technology When, the roller on one side is mainly used for sandstone and injection is mixed;The cement stock tank of another side is mainly used for water, accelerator, cement Stirring;Being delivered to spray after operating point mixes respectively by respective conveying pipeline after stirring respectively by two parts makes With;Because being that moist sandstone individually mix, cement and accelerator are directly mixed with water, so not generating dust in work;Cause To be that can reduce the blocking of drums inside in this way into roller after sandstone individually mixes, the maintenance and repair amount of equipment is reduced, if Standby consumption and labour cost greatly reduce.
