Description

A kind of new concrete mixer

Technical field:

The utility model relates to the building engineering equipment technical field, especially a kind of new concrete mixer.

Background technology:

At present, concrete mixer structure such as Fig. 1 that architectural engineering is used, usually form by motor, transmission mechanism, agitating device, feeding device, quantitative water supply installation, electric control system etc., it is to drive mixing drum after being slowed down by decelerator by motor to rotate, be fixed on the stirring vane on the mixing drum inwall, the compound that adds by feeding device in the mixing drum, bring to the top of mixing drum wall, under the effect of gravity, compound falls to the bottom of mixing drum, and required water is added by the water inlet of quantitative water supply installation from mixing drum.Like this through using for construction after the wet compound process mixing drum counter-rotating discharging after stirring repeatedly.The weak point of existing product is: the volume of machine is big, and complex structure is unsuitable for operation under as mine, the narrow and small environment of roadway, more is not suitable in roadway and the supporting use of wet concrete sprayer.

The utility model content:

In order to solve the problem of above-mentioned existence, the utility model provides a kind of new concrete mixer, the following and supporting use of wet concrete sprayer of small and exquisite, simple in structure, the suitable narrow and small environment of roadway of this equipment volume.

The technical scheme that the utility model adopted is: described a kind of new concrete mixer, its chassis is skid formula chassis, on mixing drum, be provided with gear ring and track, one side is equipped with two bearing blocks in upper part, skid formula chassis, large belt wheel is housed in bearing block, on an end of large belt wheel, big belt pulley is housed, be set with belt on the big belt pulley, the other end of belt is sleeved on the small belt pulley, small belt pulley is contained on the output shaft of motor, and motor mounting is on wherein pillar on skid formula chassis; End on skid formula chassis is equipped with support, is connected with cramp bar on support, the other end of cramp bar with the middle part of feedboard be connected, the upper part of support is connected with the following position of feedboard, an end of feedboard stretches in the charging aperture of mixing drum.

In described large belt wheel middle part gear is housed, this gear is meshed with gear ring on the mixing drum, and track and bogie wheel on the mixing drum match.

On four pillars on described skid formula chassis, four adjustable legs are installed.

The utility model and existing equipment relatively have following advantage: the skid formula is adopted on the chassis, is fit to the roadway environment, and adjustable legs is arranged, and can further adjust the stability of machine; Simple in structure, operating maintenance is easy, and reinforced stirring discharging is convenient, high efficiency; Volume is less, convenient transportation; Be applicable in mine, the narrow and small environment of roadway and the supporting use of wet concrete sprayer that the feed requirement that has solved present mine working concrete spraying machine can be widely used in every engineerings such as mine, roadway, national defence, railway tunnel.

Description of drawings:

Fig. 1 is the structural representation of existing JZC type mixer;

Fig. 2 is a structural representation of the present utility model;

Fig. 3 is that the K of Fig. 2 is to view.

The specific embodiment:

As Fig. 2, shown in 3, on four pillars on skid formula of the present utility model chassis 2, four adjustable legs 1 are installed, be equipped with four in 2 upper parts, skid formula chassis and can carry the bogie wheel 3 that mixing drum 4 rotates, mixing drum 4 is contained on four bogie wheels 3, one side is equipped with two bearing blocks 11 in 2 upper parts, skid formula chassis, a large belt wheel 10 is housed in bearing block 11, on an end of large belt wheel 10, big belt pulley 6 is housed, be set with belt 7 on the big belt pulley 6, the other end of belt 7 is sleeved on the small belt pulley 8, small belt pulley 8 is contained on the output shaft of motor 9, and motor 9 is installed on wherein pillar on skid formula chassis 2; Be provided with gear ring and track on mixing drum 4, in large belt wheel 10 middle parts a gear 12 be housed, this gear 12 is meshed with gear ring on the mixing drum 4, and the track on the mixing drum 4 and four bogie wheels 3 match; End on skid formula chassis 2 is equipped with support 13, on support 13, be connected with cramp bar 14, the other end of cramp bar 14 with the middle part of feedboard 5 be connected, the upper part of support 13 is connected with the following position of feedboard 5, an end of feedboard 5 stretches in the charging aperture of mixing drum 4.

Whether the utility model is answering inspection machine steady before each the use, and whether adjustable legs 1 firm supporting, and whether the machine dry run is normal, and gear ring and the charging machine oil lubrication of track place on the mixing drum 4.Actuating motor 9 then, the machine entry into service, and whether the inspection machine rotation direction is correct.During work, earlier in mixing drum 4, add water, begin material loading after adding water, dried mix is joined by feedboard 5 in the rotating mixing drum 4 that is driven behind double reduction by motor 9, and cement, stone, sand will prepare by certain proportioning in the concrete drier; On siccative,, add water again, continue material loading to accounting for mixing drum 4 capacity one half, the mix of observing simultaneously in the mixing drum 4 mixes condition of stirring with water, when mix is about to overflow mixing drum 4, stops to feed in raw material, and make mix mix stirring fully with water.Finish and observe the slump that mixes material when suitable when stirring, shut down, motor with reciprocating movement 9 then, and begin discharging from discharging opening this moment, and a circulation is promptly finished.
