Description

Movable cement mixer

The utility model relates to a kind of movable cement stirring device.

The concrete that the common buildings building site is used, stirring factory by large-scale concrete mixer by cement transports, stir factory and be provided with cement accumulator tank, sandstone accumulator tank, conveyer belt and tank diameter (see figure 7), wherein tank diameter is a tubular, can rotate in the original place, utilize the groove intra vane, cement, sand, stone mix are become concrete, again the concrete behind the mix is distributed to each building site.There is following shortcoming in this way:

1, because of stirring factory's needed raw material, all need to ship by the other places is large quantities of, and the concrete after stirring need be used large quantities of vehicles, transports the building site to, this has increased concrete transportation number of times, not only strengthens cost of transportation, also makes the transportation road surface impaired easily.

2, because concrete is delivered to the building site by the concrete placement vehicle of sealing, actual loading capacity and stirring cooperation ratio have no way of recording, and can influence construction quality and not foot phenomenon of Weight Loaded takes place.

3, the concrete of tank diameter stirring is sometimes without full and uniform stirring, promptly by the penetration concrete car, the rotating cylinder on the transport vehicle constantly rotates in the way though transport, but rotating cylinder function in the transport vehicle, just rotation is so concrete still often has the not uniform situation generation of mix after entering the building site.

4, concrete though the transport vehicle rotating cylinder constantly rotates, still can produce hardening phenomenon in carrying the way, if add water or the set retarder that surpasses ratio, can significant impact be arranged to concrete quality.

The purpose of this utility model is that a kind of movable cement stirring device will be provided, utilize this device can be in the building site direct mix concrete, and conveniently moving, thus both can guarantee concrete quality, can reduce freight again, save cost.

The purpose of this utility model is achieved in that this movable cement stirring device, by the fixed support that is installed on the transport vehicle, mixing drum and transmission device constitute, in cylinder, be provided with the spiral shell leaf that circles round of formation wavy surface in thorax surface in making on the thorax face, circling round between the spiral shell leaf, the puddle support that is provided with, the mixing drum end is provided with flip, the flip center is provided with the bearing that is installed on the cross bar, the cross bar both sides are connected with the movable rod that is articulated on the fixed support, each is connected the cross bar two ends with hydraulic cylinder, and the hydraulic cylinder other end is articulated in again on the fixing pole by frame both sides rear side.During use, the concrete of in cylinder, mixing thoroughly, can be in cylinder rotates in hydraulic cylinder in time open flip and discharge application.

The utility model has the advantages that this device conveniently moving, utilize this device can be in the building site direct mix concrete, both can guarantee concrete quality, can reduce the transportation number of times in the concrete production process again, thereby reduce cost, useful protection road surface.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

Fig. 5 is the utility model embodiment 1 schematic diagram.

Fig. 6 is the utility model embodiment 2 schematic diagrames.

Fig. 7 is that tradition stirs factory's facility allocation plan.

Below in conjunction with accompanying drawing, describe concrete structure of the present utility model and working condition thereof in detail.

With reference to the movable cement stirring device of Fig. 1-4, comprising:

One fixed support 2 is located at the rear of transport vehicle 1, and support 2 tops have a left and right sides pole 21 and a holder 23 that tilts, and on left and right sides pole 21 and holder 23, are respectively equipped with the I shape roller 22 of mutual correspondence;

One mixing drum 3 is located between left and right sides pole 21 and the holder 23, and cylinder 3 outer rims are provided with slide rail 31, this slide rail 31 and I shape roller 22 tablings;

One transmission mechanism reaches the chain that is meshed with the gear 37 of mixing drum 3 outer rims by motor and is constituted;

On the thorax face, have the spiral shell leaf 4 that circles round of formation concavo-convex fluctuating wavy surface in thorax surface in making in the mixing drum 3, be provided with puddle support 5 at 4 on the spiral shell leaf that circles round, puddle support 5 central authorities are provided with the mesh that concrete material is passed;

The mixing drum 3 terminal outsides, be provided with flip 31, flip 31 centers are provided with bearing 33, bearing 33 laterally is connected with cross bar 34, each is connected cross bar 34 both sides with movable rod 35, movable rod 35 is hinged with the rod member that is fixed on the left and right sides pole 21, and each is hinged cross bar 34 two ends with a hydraulic cylinder 36, and hydraulic cylinder 36 is articulated on the pole 21 ' of fixed support 2 both sides rear sides.

During use, with cement, sand, stone, water is positioned in the mixing drum 3 by match ratio, the hotwire (not shown) drives chain, mixing drum 3 is axially rotated, the rolling friction that slide rail 31 and worker's type roller are 22 has prevented the off normal of cylinder 3, and can reduce frictional resistance, because flip 32 centers are provided with bearing 33, so during cylinder 3 rotations, bearing 33 maintains static, and just flip 32 is rotated thereupon, at this moment spiral shell leaf 4 formed depressed parts that circle round in the cylinder 3, can guide sand, stone, cement rolls, mix, borrow the mesh sieve of puddle support 5 to leak simultaneously, make concrete material be able to full and uniform stirring, cylinder after stirring is finished, when continuing rotation, utilize the spacing of the contraction of hydraulic cylinder 36 and movable rod 35 and raise up, make concrete be able to gush from cylinder discharging opening 6 along the gradient of cylinder 3 and the guiding of the spiral shell leaf 4 that circles round, can be to building with the concrete pressure injection, treat concrete topple over finish after, before flip 32 is covered by hydraulic cylinder 36,, flip 32 is closely covered with water jet 38 hydroblastings.

With reference to Fig. 5, when this device was used in the less building site of concrete demand, available one had the gravel car 7 of conveyer belt, will stir in materials such as cement, sand, stone, the water input mixing drum 3.

With reference to Fig. 6, when being used in the bigger building site of concrete demand, then can acquire metering conveying equipment 8 in the front side of transport vehicle 1, this equipment 8 is mainly by water tank 81, belt conveyor 82, and measuring tank 83 form its sand, stone, raw materials such as cement utilize above-mentioned gravel car 7 to be transported to simultaneously in the different measuring tank 83 again, and are measured by micro computer, material usage in the control concrete, and deliver in the cylinder 3 by conveyer belt, water can be delivered in the measuring tank 83 by a water pump in the water tank 81, again in the impouring cylinder 3, and take advantage of a situation and wash away inlet, reach directly and evenly stir, save cost of transportation, guarantee concrete quality, purpose easy to use.
