Description

This invention relates to concrete pitch

of continuous operation, in which case the dosing bodies of the concrete block, mounted on one roller mixing unit, consist of scoop wheels for grabbing gravel, sand and cement, equipped with buckets for collecting these materials along trays into a collecting box located in front of the mixing drum. The proposal is aimed at giving such a device a concrete block that, with the possible simplicity of the design, would automatically allow accurate dosing of the components

parts of concrete of any composition, would produce intensive mixing and produce ready-made concrete in a continuous stream.

In FIG. 1 shows a longitudinal section of a concrete cast (along the line AB of FIG. 2); FIG. 2 is a plan view; FIG. 3 is a sectional view of the CD effect of FIG. one; FIG. 4-view n plan scraper; FIG. 5-View in plan and section of the discharge tray; fig.b - section along the line /: / fig. one.

Concrete works as follows. Solid constituents of concrete, such as gravel, sand and cement, are taken out of the loading buckets /, 2, 3 (Fig. 1) with the help of hard wheels (7, 18 and L) mounted on the common

drive shaft. G:

(366) / - V

Crap wheel 4 for cement, covered with casing to protect against cement dust. When the wheels rotate, the material-filled scoops rise and, reaching the highest polo, tilt the contents into trays 5; 5, 7, by which materials are directed by gravity to mixing organs. The trays 5 for gravel and sand for sand are open, while the cement tray 7 represents a closed box to avoid the formation of dust. All trays lead to a prefabricated closed box S, to which the amount of water necessary for mixing from the water meter 9 is also sent to. the power of the pipe W. The collection box A passes under the cement receiving bucket and guides the mixture of materials formed by moving along the box into the trough, where the mixture is mixed in a forced manner with the help of jingles J2 mounted on a common drive shaft. By moving the kneading needles, to the ends of which the blades of a plow-shaped form are screwed, concrete is directed along a slope to the bar-. a ban J3 mounted on the same common drive shaft and equipped with pocket-shaped diaphragms 14. As the drum 13 rotates, the concrete is once more stirred by the action of a free fall

when distributed in pockets, the latter rises upwards and pours out onto the unloading open tray / 5, through which the gravity flows to the "destination".

In order for the mixing operation to occur until the Seton exits from the end of the discharge tray, the latter is provided with transverse partitions (Fig. 5). By setting the appropriate amount of scoops to the wheels for gravel, sand, and cement, you can dispense concrete of any composition. In order to maintain the exact volumetric content of the scoops, the latter, after loading with material, are leveled with a special scraper / b (Fig. 3 and 4), which removes excess material from the scoop above its edge. The scraper consists of a fork-shaped guide, the lower part of which has the width of the loading bucket and is attached by means of hinges to its side walls. Attached to the upper, curved part of the fork is a convex ruler of strip iron, whose length is equal to the width of the scoop. In the initial position, the crab is positioned in such a way that the edge of the ruler touches the rear edge of the scoop. When moving the scoop wheel, the ruler moves towards the front edge of the scoop, removing the excess material and dropping it back into the loading bucket. The curvature of the plug is designed in such a way that it slides along its outer edge when the scoop moves. Until the scoop reaches its horizontal position, the scraper line comes off the top perimeter of the scoop and, on further movement, first slides along the side surface of the scoop, and then lowers to the rear edge of the next scoop, where the process of generation repeats, etc.

Dp dosage of water is applied to an existing type of water meter.
