Definitions
- An invention relates to the method according to claim 1 for making concrete in a mixing bowl and for transporting it by using same mixing bowl to casting station, which is generally a casting mould or a plane-like structure.
- the charging of the mixer is carried out mechanically at least concerning sand and water charging, the amounts of which are adjustable, too and the concrete mixing is carried in the mixer straight to the casting place.
- Fig. 1 is a side view of a work machine and a mixer.
- Fig. 2 illustrates a mixer
- Fig. 3 is a front view of a work machine and a mixer.
- Fig. 4 illustrates a work machine charging sand.
- FIG 1 is an embodiment, where a self-moving excavator 1 is as work machine. It is equipped with a grap-like bucket 5 having two parts and a water tank 3 has been formed in one of its booms. To the grab bucket 5 has been coupled a mixer 4. The excavator can take and transport said mixer to desired station. The mixer 4 has been partly filled with sand which has been loaded by the grab bucket of the excavator. The excavator lays the mixer 4 on the ground and can take sand with its grab bucket as far as the hoses 9,10 permit which are coupling the mixer to the hydraulic system of the excavator.
- the boom 2 of the machine has a flexible support 14 for the hoses.
- the grab bucket 5 has such a form that by means of it a known amount of sand can be charged repeatedly for ex. using the maximum load of the grab bucket.
- the boom 2 has a water tank 3 for supplying water to the mixing bowl 4. There is many possibilities for adjusting the water amount. With water valve can be used a time relay which adjusts the water flow time. Cement can be charged in the mixing bowl by sacks. Cement can be loaded by means of the bucket 5, too.
- FIG 2 is formerly known concrete mixer 4, which has an embodiment of quick locking needed according to the invented method.
- the upper part of the mixer has a beam 6 on which arms 7 have been mounted turnable around joints.
- the hydraul ⁇ ic cylinder 8 turns the arms.
- the opening and closing of the locking means 7 are depending on that which one of the hoses 9 or 10 is used as supply line and which one is used as return line.
- the mixing bowl 4 can thus be transported carried on by the grab bucket 5.
- the mixing bowl has a discharging opening (not shown) in the bottom, through which the concrete mixing can be adjustable dis ⁇ charged to casting moulds.
- figure 3 is a front view of the work machine 1.
- the middle part of the grab 5 has a shoulder behind which the arms 7 are locking and preventing the bowl to drop from the bucket.
- the excavator 1 is loading sand in the mixer 4.
- the mixer blades are rotating continuous.
- the pressure hoses are so long that the excavator can take sand from distance of several meters to the mixer.
- the sand amount can be adjusted also by weighing when the height of actual pressure in some of the boom cylinders shows the weight when the bucket is lifted up.
- gauges can be used which are measuring the load of the boom or its parts when the bucket contains sand.
- the measuring of cement amount by weighing is carried out in the same way. Water charging can be carried out by weighing, too, the flow meter can be used or by means of measuring time when water is running to the mixer.
