Description

/. .

The aim of the invention is the constructive improvement of the existing mechanical adjustment of the water supply to the ponerca%, for which the concreter measuring device is sewn with one or two moving walls, changing its capacity, according to the required water supply.

In FIG. Figure 1 shows a general view of the entire machine of the Mixing Concrete or Mortar Machine with the measuring device, part of which is shown in section; .fig. 2 shows a measuring device with a telescope cylinder; FIG. 3 - detail of the measuring device. In section; FIG. 4-device of the measuring device with a plunger and a three-way valve for connecting to the water supply system; FIG. 5-cross-section of the crane; FIG. 6 is a longitudinal section of the measuring device with a modified device for installing a piston; FIG. 7 is a vertical section taken along line AB in FIG. 6 ...

Concrete shown in FIG. 1, moles from the drum 1 for mixing concrete or mortar, driven by an electric motor 2, the drum and the motor are mounted on a mobile

frame 3. It also has a platform 4, on which is a tank for water at the top, under the tank there is a measuring device 6, which, as shown in FIG. The first embodiment is made in the form of a cylinder 7 with an installable piston 8 fitted tightly to the cylinder. Through one of the frontal walls of the cylinder a screw spindle 9 passes, one end of which is connected to the piston 8, while a handwheel is mounted on the other end .10. The spindle hub is designed as a nut and is threaded according to the spindle thread. By turning the handwheel, you can move the spindle and piston in either direction and thereby change the capacity of the measuring cylinder. The cylinder or its stand has a scale 11 with a pointer 12, so that by the position of the pointer you can find out the capacity of the measuring device. The latter has a gauge glass 13 for monitoring the degree of filling. The tank 5 is connected with the measuring device 6 by the tube 14, in which a stop valve 15 is arranged. From the measuring device to the drum 1 leads a discharge pipe 16 to the stop valve 17. The levers from the valves 15 and 17 are connected to each other by a hard 18 so that when one the tap is open, the other is closed. The lower crane lever 17 has a handle 19, by means of which the valves can be moved in one direction or the other. Pipe 20, installed at the top of the measuring device, serves to release air. According to the second variant (Fig. 2 and 3), a measuring cap 8 (1. The cap overlaps the open end of the cylinder 7) instead of a moving piston. With a larger capacity of the measuring device, with both adjustable caps, both ends of the measuring stick overlap. The retractable cap has a flange 21 (Figs. 2 and 3), against which the flange (ring) 22 is located. By means of bolts 24 seconds, the wings 23 of the flange are pressed against each other. An elastic layer 25 is placed between them.

The gauges in the first and second versions work as follows: the handle 19, the taps 15 and 17 (Fig. 1) are installed in the position indicated by the dotted line, in which the upper valve is open and the lower valve is closed.

The measuring device 6, the capacity of which is regulated by the piston 8 (Fig. 1) or the cap 8a Hfig. 2), is filled with water through the tube 14. When the filling is completed and at the same time a certain amount of material to be mixed is introduced into the drum 1, the handle 19 is pulled to a position where the upper valve 15 is closed and the lower valve 17 is open. Then the emptying of the mernik proceeds into the concrete drum. This process is repeated with each load of concrete.

In the third variant, the measuring device 7 when moving the piston 8. (Figs. 6 and 7), the latter does not rotate due to the special arrangement of the spindle 32. The spindle 32 rotates in the sleeve 33 of the piston, equipped with a screw thread, and its pin 34, with the impaled, with the handwheel 43, lies in the sleeve 44, in which it cannot move. ,

 The piston is fixed in the direction of the measuring axis of the tube 35, supported by a crossbar 36 with a sleeve embedded in the center. Inside the tube is positioned with a screw spindle 32, and its outer surface is provided with a rib 37 sliding in the guide 38 in the crosspiece 36 and preventing the tube from rotating. On the pin 34 of the spindle 32 there is an endless screw 40 which engages with the screw of the index mechanism 42, which controls the movement of the piston, and at the same time the capacity of the measuring device. By numeral 39, a cylindrical guide for moving tube 35 is attached.

To connect the measuring device 7 (Fig. 4 and U to the water supply (instead of the tank), a three-way valve 27 is inserted into the tube 31 to connect with two further tubes 28 and 29; of these, one 28 is connected to the aqueduct, and the other 29 is connected to the drum This valve, at one position, fills, and at the other, empties the measuring device.

So that after filling the measuring device it was possible to close it and, when emptying, to remove air from it, air inlet 20 (Fig. 4) with a fitted valve consisting of box 45, in which the float 46 and valve 47 are located, is available for exhausting the air. A float with a valve is pressed against the valve seat. When emptying the measuring device 7, the float is lowered and opens access to the air.

The subject of the patent.
