Description

Inventory c. et1; spring loaded weigher for inert aggregates of concrete, in which a hydraulic actuator is used to open the feed hopper and the sectoral shutter of the weighing tank, switchable from the paddle of the spool valve "t Tiopa" fixed to the tank root.

In this dispenser device, the thrust washers of the Afusens, which are supported by the coEoii tank, are connected to the iiopntHcii rods of the hydraulic cylinders, in order to adjust the tension of the weight springs to different ones; weight measure

FIG. 1 shows a weight metering system; in fig. 2 is a view of the dosage device according to (AA); FIG. one; in fig. , - scheme of hydraulic weighing dosing.

In the device, the weigher, the dispenser is applied a hydraulic p; i.indr (1), the piston pg of which is connected to the shzhber (2), inserted at the bottom of the conical part of the bunker. When moving, the viravo piston opens the gate (2); the gate is closed by a spring (3).

Under the gate of the bunker, there is a ve (the mowing doeator tank (4), the weight springs (5) and the bearing} ia of its Ko-piryce stop (6), Kotarsh, when the reservoir settles eight).

The iCoe spool distributor is a pipeline with a hydraulic cylinder (1) and has two overflow holes (9) inlet (10), connected by a pipeline with a pump (11), and an outlet from (12), connected by pipeline with a tank (13) .

In the lower part, the weight tank ends with a sector shutter (14), an openable piston chi, tindra (15), UNOnHN01X) pipe ducts (up to 5 | with nucoci.

A cylinder (16) is installed to switch on the dosage on the same axis with the vintage distributor (8).

Strokes the front of two .hydraulic cylinders (17) of co-dipen with lyor washers (5) to adjust their tension to different weights.

The operation of the dispenser is produced as follows.

To activate the handle, the cylinder turns on the cylinder (16), the piston of which is connected with the piston to the piston of the cylinder-type spool valve (8). Under pressure, the pistons both raise and the piston hole (10) opens from the pump (I), which is constantly included with a certain pressure. Opening (12) is blocked at this moment, and the cylinder (1) rushes under pressure.

The cylinder piston (1)

a rod with a gate | (2) moving on rollers to an angle (Path. Gate opens to the magnitude of the stroke of the pole and the ET031 stretch expands the spring (3). Through the Open Hole Sylushp} The springs (5) are compressed, lowered and compressed, designed to permanently settle them when the maximum load is loaded.

When lowering the reservoir (4), the ulor (6) presses against the flange (7) of the spool valve (8). The stroke is expanded so that it leads into the hole (10) and opens BbiHycKim) e hole (12) into the tank (13). As a result, the pressure in the hydraulic cylinder O) drops sharply, and LRU (3) is compressed and cuts off the flow of pulverized material and the flow into the reservoir. At this time, the cylinder cylinder (16) is also in the lower position.

When the tank is emptied), the cylinder (15) turns on, a sector valve opens. (14) the bulk material is poured out into the peristalted drum of the concrete mixer.

When the tank is released from the load, the prulot (5) expands and raises it to its previous upper position. In this case the cylinder cylinder. (16) spool-containing radar-titres are located in the bottom position, so that the battery (6) is not connected with L1TOK l &rs; and slides freely.

The closing of the sectoral shutter (14) takes place in people own / weight, and the cylinder (15) is turned off.

In order to repeat the cycle, it is necessary to turn on the cylinder (16).

Subject invention

1. The weight spring1nn1 dispenser for inert fillers betola, different 10n (and with the fact that to control the gate of the supply bin and the gate of the spring tank, a hydraulic drive is applied, switched with the help of the gold dispenser from the unor reinforced on tank housing.

2. The form of performance of the weighting agent of the INTEGRAL dosing unit for inert fillers of betol in l. 1, characterized in that for adjusting the tension of the shears' springs on a different set of weight, the spring washers of the prulsins are connected with the rods of the hydraulic cylinders.
