Description

genus

The invention relates, for example, to and arranged on a chassis by a trailer hitch or the like - preferably by means of a Cars - mobile high-performance machine combination for mixing and Conveying flowing screeds.

State of the art

It is known to provide dry mortar on construction sites in standing silos, which are filled by tankers if required. The individual stand silos are machine combinations consisting of at least one drive motor Tor and a pump assigned so that the dry mortar after  Mix with water as self-leveling screed via a hose line to the in location can be pumped.

This known design requires a machine combination for each silo from drive motor and pump as well as, if necessary, mixer shaft and what task and must be together with the stand silo of special vehicles be transported. As a result, the weight of the silos is relatively high, what at the expense of the storage of dry mortar, since the Spe Total vehicles to be transported due to relevant Ge law is limited.

Another disadvantage of this solution is that the capital requirement is relatively high, since each silo with the described machine combination is equipped, even those that are not or not in use for a while Find.

That is why a high-performance machine combination has already been proposed nation, consisting of a steep screw conveyor, a horizontal continuous mixer and feed pump and drive motor on one by means of a car or the to mount the same movable chassis. The steep screw conveyor conveys the dry material from the standing silo into the hopper of the conveyor mixer. A spiked wave continuously mixes the screed and transfers it him the feed pump, which mixes the finished screed over a hose promote to the site.  

This construction has the disadvantage of a relatively high overall height, since the Steep conveyor screw requires a considerable amount of space to accommodate it, because it protrudes above the hopper of the continuous mixer. Except such steep augers are relatively expensive and require demge a high investment. Because the dustproof connection of the steep conveyor snail over a bellows at the lower discharge opening of the funnel of the stand silo, additional space is required in height. There the high-performance machine combination is firmly connected to the chassis , it can happen that these do not or only after digging away Arrange floor layer under the stand silo. The chassis protrudes with the rest of the machine combination between the feet of the Silos, which is annoying.

From the brochure "S5 universal screw pump" from Putzmeister, 72631 Aichtal, pages 1-6, published at bauma ′95 on April 5, 1995, is a arranged on a chassis and by a trailer hitch or similar movable high-performance machine combination for the Mi known and conveying flowing screeds known at an outlet a dustproof silo is coupled with a motorized drive NEN horizontal continuous mixer with dosing screw for conveying the dry material supplied by the standing silo, as well as a mixer shaft Mixer tube and water connection, a pump for the leveling screed and one  motor drive unit for driving the pump. The mixer tube is expandable.

In addition, no previous publication was published in one of the applicants German patent application (DE 195 36 958 A1) already published one a chassis arranged and by a trailer hitch or the same - preferably by car - movable high-performance machines combination for mixing and conveying flowing screeds, the is to be coupled dust-tight to an outlet opening of a standing silo, with a Motorized horizontal continuous mixer with dosing screw for Conveying the dry material supplied by the standing silo, one Mixer shaft with mixer pipe and water connection, a pump for the flow Screed and a motorized drive unit for driving the pump and at least one motor drive for height adjustment of the on a Frame of the chassis with a high-performance machine arranged on it combination. Furthermore, in this unpublished Pa a similar high-performance machine combination is proposed beat, in which by means of a metering screw by gravity conveyed dry material is conveyed further, with a coaxially arranged Mixer shaft in a mixer pipe with water connection and one below arranged pump funnel into which the mixer discharges, with a one-sided the motor drive unit for the drive assigned to the pump funnel a pump shaft and a screw arranged coaxially thereto, the  Longitudinal axis of the pump shaft and the screw transversely - preferably orthogo nal - to the longitudinal axis of the dosing screw and the mixer shaft and below the longitudinal axis of the pump shaft, the screw and the mixer shaft are arranged and run below it. On both sides of the Fahrge each is at least one motor drive, for example a piston cylinder the unit, spindle drives, electric motors or the like for lifting and Lowering the vehicle frame with a high-performance machine combination arranged. The high-performance machine combination is over several Couplings, which are opposite one another in pairs, releasably with the To connect the frame of the chassis. On this chassis is also a hydraulic fluid tank arranged from which by means of a hand pump or the like hydraulic fluid via a check valve and via a 3/2-way ball valve, preferably alternately, in two separable lines is conveyable, each via a 2/2-way check valve and via a Line to each cylinder space of the piston-cylinder unit concerned are closable.

This construction, which has not been previously published, already eliminates the ones described Disadvantages in that the high-performance machine combination immediately to drive with their mixing funnel under the outlet opening of the standing silo and is to be lifted in order to connect this device to the standing silo in a dust-tight manner the. Then the chassis can be lowered and moved away, so that it doesn't bother on the construction site. A steep screw conveyor is no longer  required so that the necessary investments are no longer necessary. This eliminates len also the maintenance and repair work on such Steep conveyor screws. Since the chassis is adjustable in height, it can be attached to the conditions at the place of use are adjusted so that earthworks, especially shoveling away layers of earth for the purpose Creation of sufficient free space for arranging the high-performance Machine combinations are also no longer required. Here is a be special advantage to see that the high-performance machine combination only need to be driven to the silo that is currently needed. If the high-performance machine combination is flanged to a standing silo, the chassis can now be used for other purposes. They don't Stand silos required are therefore not combined with high-performance machine combinations equipped. Stand silo distributors spend less capital, because with a relatively small number of flexibly handled Hochlei machine combinations a relatively large park of standing silos drifting.

Otherwise, the high-performance machine can be used in a very compact design Arrange the combination on a car trailer. Such a feat machine combination can, for example, a delivery rate of 70 have up to 120 liters per minute.  

It often happens that stand silos are not completely emptied that the customer has misjudged the quantity ordered there is work stalling and there is a risk that construction binds the fabric mixture in the stand silo. In addition, it is also possible that Work will be interrupted or at a later date screed work ten must be continued, so that in the meantime the stand silos do not can remain on the construction site as they are otherwise required. In in this case the stand silos must be transported away. Are you still partly filled with dry mortar, their weight can be high.

In all these cases it is advisable to empty the stand silos beforehand, so that they are not only easier to transport, but rather that Dry mortar can be used for other purposes and the risk is eliminated is concluded that he unintentionally sets in the stand silo. That's why you have already proposed in cases where the stand silos are not or for are no longer needed for some time to empty them through a device ren, which represents a special aggregate that the stand silos concerned must be brought there. These facilities are large and bulky require investment.

task

The invention is based, for example on a driving task rack to be arranged and movable by means of a car or the like High-performance machine combination for mixing and conveying flow Form screeds so that the relevant high-performance machine combination nation can be set up in a few simple steps so that you can use it Have the standing silos of dry mortar empty.

solution

The object is achieved by the features reproduced in claim 1 solved.

Some advantages

The high-performance machine combination according to the invention can be used as in the unpublished older German patent application, the above ge has been used to mix and convey liquid screed. It can also be used to empty a standing silo, namely in a simple manner that the mixing tube, for example, by Quick fasteners with the metering tube and is arranged coaxially on this, is replaced by a blow head which is connected to a compressed air source on the one hand  Example a compressor of the silo vehicle, and on the other hand to a För connected to the discharge into the silo vehicle. This can the high-performance machine combination that is already on the stand silo is flanged, remain in its position and completely empty the silo, by applying air pressure into the blow head through the compressor of the silo vehicle is entered, from which the remaining amount, which via the dosing screw is conveyed into the blow head, is blown back to the silo vehicle. The plant, which is already in the metering tube, prevents this dry mortar plugs a blow back of the air pressure over the dosing snail to the stand silo. One will therefore usually proceed in such a way that first the compressed air supply to the blow head is switched on and then the motor drive for the dosing screw is set in motion, whereupon the dosing screw not only the dry mortar plug in the blow head, but also the one located in the standing silo, in the Silage vehicle dry mortar to be returned.

The blow head can be a simple tubular housing that requires correspondingly low investments, is easy to handle and attaches itself in a few simple steps, for example with quick couplings In place with a suitable opening coaxial to the metering tube can be arranged.  

In this way is a separate device for conveying from standing silos dispensable. The blow head can be used as an additional component with the high-performance Ma rail combination can be moved, for example at hand in one place the high-performance machine combination can be stored so that it in Emergency trap is immediately at hand.

This means that stand-alone silos can be emptied quickly and easily.

3 as is apparent especially from FIG., The dosing shaft 20 is coaxial with the Mi shear wave 21 is arranged. The latter has wings for more intensive mixing of the mortar mixture.

Through the claw coupling 60 , a tube or a hose for fresh water supply is flanged so that water can be added to the mixing tube 5 via the angle 59 . Entered by the dosing screw 20 in the mixing tube 5 pipe mortar mixture in the form of factory dry mortar is intensively mixed with the water and conveyed down into the pump funnel ter 2 , from where the pump shaft 13 with its blades for further mixing and further conveying to coaxially arranged screw 22 in a housing-shaped screw shell 23 provides. From there, it is transported further via the sheet 58 to a hose line coupled via the quick coupling 45 , so that the self-leveling screed can be pumped to the place of use.

It can be clearly seen from a comparison of FIGS. 1 and 2 that the Doier screw 20 with the mixer shaft 21 extends orthogonally to the longitudinal axis of the pump shaft 13 and the screw 22 . Furthermore, it can be seen that the pump shaft 13 with the screw 22 is arranged below the mixer shaft 21 . The housing 3 with the attachment 26 , the bevel gear motor 35 , the metering screw 20 and the mixer shaft 21 are arranged above the cabinet door 43 and the control plate 32 and also above the tool cabinet 25 . This results in a compact, space-saving construction.

The reference numeral 85 ( FIG. 9) indicates a chassis designed as a trailer, which has a trailer coupling 86 , by means of which the chassis 85 can be coupled to a car or the like. The chassis 85 in the present case has two wheels, one of which is designated by the reference 87 . Wheel housings bear the reference numbers 88 and 89 .

The chassis 85 has a stiffened construction 90 in the middle length range, on which the high-performance machine combination according to FIGS . 1 and 2 can be placed. In the transport position, the high-performance machine combination is locked by couplings 91 , 92 and 93 , 94 , which can be locked and released by hand, to which hand levers are assigned. Only one of the hand levers has been given the reference number 95 . The high-performance machine combination according to FIGS. 1 and 2 has on its underside corresponding locking pieces, no longer designated, with which the couplings 91 to 94 can be brought into and out of engagement.

96 is a stabilizing wheel, which is common for trailers and can be adjusted orthogonally to the floor 98 by means of a hand crank 97 . For the purpose of transportation, the stabilizing wheel 96 is raised up to directly under the frame 99 . Opposite pairs are arranged on the frame 99 four or thogonal to the floor 98 extendable supports, of which only the two supports 100 and 101 located on one longitudinal side of the frame 99 have been provided with reference numerals in FIG. 8.

Such supports are arranged on the opposite side of the frame 99 . This makes it possible, if necessary, to leave the high-performance machine combination on the chassis 85 in operation and to bring about the necessary stability.

In the area of the wheel arches 88 and 89 , a piston-cylinder unit 102 and 103 ( FIGS. 11 and 12) are arranged on each side of the trailer 85 , the one with the frame 99 and the other with the axis 104 of the trailer gers 85 are in operative connection. The frame 99 can be raised or lowered via the piston-cylinder units 102 and 103 , that is to say in the direction X or Y and therefore orthogonal to the floor 99 .

The piston-cylinder units 102 and 103 consist of the illustrated embodiment from each one-sided hydraulic pressure on cylinders 105 and 106 ( Fig. 10), in which pistons 107 and 108 are longitudinally displaceable and sealing. On one and the same piston side, lines 111 and 112, respectively, open into the cylinder space 109 and 110 thus created, for supplying a hydraulic medium. Lines 111 and 112 are connected via 2/2-way shut-off valves 113 and 114 to lines 115 and 116 , respectively, which lead to a 3/2-way ball valve which, in the position shown in FIG. 10, is in the locked position located so that none of the lines 115 and 116 is connected to a line 118 which is connected via a throttle 119 to a line section 120 which leads to a hand pump 121 with a hand lever 122 .

At 123 , a line section is indicated, which is connected on the one hand to the line 120 and on the other hand via a shut-off valve 124 and a line 125 to a hydraulic fluid tank 126 .

Reference number 137 denotes a bypass line with check valve 127 .

At 128 and 129 stroke stops are designated, while 130 and 131 are fixed cams that interact with notches 132 and 133 .

The double arrow FT in FIG. 10 denotes the switchover position of the 3/2-way ball valve 117 .

The mode of operation of the embodiment shown in the drawing is the following:

Assuming the frame 99 is in the lower, lowered position shown in FIG. 12, then the high-performance machine combination nation rests on the frame 99 and is locked to the chassis in the transport position via the couplings 91 , 92 and 93 , 94 , respectively and can be driven away. The supports 100 and 101 and the corresponding opposite supports are in the raised position shown in FIG. 8. In addition, after the trailer is coupled to a car or the like, the stabilizing wheel 96 is screwed upward in the Y direction via the hand crank 97 .

The entire unit can then be moved to the place of use, for example to a standing silo 134 , as can be seen in FIGS . 5, 6 and 7. By means of a car or the like, the entire unit is then moved in the lowered position from under the opening of the outlet funnel of the standing silo 134 , that the inlet opening of the housing 3 is as coaxial as possible under the mouth opening or the flange provided here.

The shut-off valve 124 is then opened and the hand pump 121 is started via the hand lever 122 , which then sucks in hydraulic medium from the hydraulic fluid tank 126 and via the line 120 and via the check valve 127 and the bypass line 137 as well as via line 118 of FIG. 3 / 2-way ball valve, for example, via line 115 and the 2/2-way shut-off valve brought into operative position via catch 132 and cam 130 and line 111 pressed into cylinder chamber 109 . The 3/2-way ball valve has previously been pivoted in the direction T so that the liquid can enter line 115 via line 118 . The Kol ben 107 and thereby also the piston rod connected to it is pushed out of the cylinder 105 and thereby lifts the frame 99 on one side. After several pumping movements, the 3/2-way ball valve is turned in the direction F, which now leads line 116 and, via the 2/2-way shut-off valve 114 , which has also previously been brought into its open position, line 112 and thus the cylinder chamber 110 can be acted upon by hydraulic pressure, which likewise results in a displacement of the piston 108 and thus the piston rod, so that the frame 99 is now also raised accordingly on this side ( FIG. 11).

This process can optionally be repeated several times until the frame 99 is at the appropriate height, such that the housing 3 is at such a height that it with screws or the like with the outlet opening of the lower funnel of the Standi los 134th can be connected dust-tight. This also makes it possible to adapt to uneven floors. With the reference numerals 138 and 139 swinging are designated. One of these rockers 138 and 139 is assigned a Kol ben-cylinder unit 102 and 103 , respectively. These rockers 138 and 139 are each pivotally coupled to the frame 99 in a vertical plane via a pivot axis 140 and 141 , respectively. As is known from FIGS. 11 and 12, the piston rod 135 or 136 engages via a pivot axis 142 or 143 on the rocker 138 or 139 .

The inlet opening of the housing 3 is connected in a dust-tight manner to the lower outlet opening of the standing silo 134 via a flange and screws or the like.

Thereupon, by appropriately pivoting the 3/2-way ball valve, the cylinder spaces 109 and 110 can alternately be relieved of pressure, the oil via the throttle 119 and the line 120 , 123 and the shut-off valve 124 and the line 125 in the hydraulic Liquid tank 126 flows back.

If the altitude taken should be blocked, the shut-off valve 124 can be closed. In addition, the 2/2-way shut-off valves can be brought into the shut-off position shown in FIG. 10.

Should during lifting of the frame 99 via the piston-cylinder units 102 or 103, the stroke stops 128, 129, the zen welcome the maximum stroke position is reached, the 2/2-way check valves 113 and this stroke stops 128 and 129 114 immediately actuated in such a way that they reach the locking position shown in FIG. 10, so that the cylinder spaces 109 and 110 are automatically blocked against unintentional lowering.

The reaction forces of the piston-cylinder units can be initiated via the axle 104 of the trailer and thus via the wheels 87 in the floor 98 . Either cylinders 105 and 106 are coupled to frame 99 and piston rods 135 and 136 - indirectly - to axis 104 , or cylinders 105 and 106 direct the reaction forces into axis 104 , while piston rods 135 and 136 frame 99 lift.

Through the shut-off valve 124 an additional security against unintentional lowering of the frame 99 , for example falling down, is prevented, as is also the case with the movement of the entire assembly by the blocking position of the 2/2-way blocking valves 113 and 114 shown in FIG. 10 unintentional movement of the piston-cylinder units 102 and 103 is avoided.

FIG. 13 now shows the arrangement in which the mixing tube 5 ( FIG. 1) is replaced by a blow head 144 . For this purpose, the blow head 144 is flanged over Schnellkupp lung 145 with a tubular mouth 146 coaxially to the metering tube 4 , so that the metering screw 20 can discharge through the Mün opening 146 in the blow head 144 .

The blow head 144 consists essentially of a tubular housing 147 , which is provided on its end facing away from the metering tube 4 with a reinforced wall 148 , in which a support shaft 149 for supporting the Doier screw 20 is arranged, which has a reduced diameter over the end the support shaft 149 is pushed. The support shaft 149 is arranged in a bearing 162 at its end facing the wall 148 .

Transverse to the longitudinal axis of the metering tube 4 , a blower housing 150 is connected to the housing 147 of the Blaskop fes 144 , which has a length section 151 which essentially corresponds to the diameter of the tubular housing 147 . This length section 151 is followed by a conically tapering length section 152 , which in turn is followed by a tubular section 153 with a short connecting piece 154 . The longitudinal sections 151, 152, 153 and the connecting piece 154 are integrally connected to one another and, like the entire blow head 144 , are generally made of steel.

As can be seen in particular from FIG. 15, a delivery line 155 is connected to the nozzle 154 , which leads to a silo vehicle 156 . The För derleitung 155 can be a hose line, for example an armed hose line, which is pressure-tight to connect to the nozzle 154 (not shown).

The silo vehicle 156 has a compressor 157 and a filter 158 , for example a filter bag, through which the conveying air exits to the outside.

A compressed air line 159 is connected to the compressor 157 and is connected to the blower housing 150 via a connecting piece 160 .

Reference number 161 schematically indicates a dry mortar plug in FIG. 17.

If the silo, which cannot be seen in FIGS. 13 to 17, is to be emptied empty by a residual quantity, the silo vehicle is moved into position and connected via lines 155 and 159 to the blow head 144 in the manner shown in FIG. 15. Then the compressor 157 is switched on and air pressure is supplied via the nozzle 160 to the blow head 144 . Then the motor drive of the dosing screw 20 is put into operation, so that it för the dry mortar plug 161 in the tubular housing 147 för changes. The material then falls into the blower housing 150 and is then conveyed through the compressed air over the longitudinal sections 152 , 153 and the connecting piece 154 into the delivery line 155 and from there into the silo vehicle 156 .

As can be seen, the conversion can be carried out very quickly, since the mixing tube 5 only needs to be exchanged for the blow head 144 via the quick couplings 145 in order to use the high-performance mixer combination in the manner shown in FIG. 15 with a silo vehicle 156 to be able to connect via lines 155 and 159 so that the remaining amount of material can be transported away from the silo in question. Of course, the connection at the mouth 146 and the silo 156 is dust and mortar-tight in the required manner, so that no material can escape here. This material passes from the tubular housing 147 by gravity into the longitudinal section 151 .
