Description

The invention relates to semi-automatic weights for loose bodies, consisting of a rocker arm with one ball attached to it and equipped with a charging hopper with a flap that is held in the open position by means of latches.

In the proposed weights, a sector-shaped damper is connected to a cable that bends the pulley of the flap and carries a load at the end that serves to close the flap. In the open position, the flap is held by a slider placed on the cable by means of a lever and pull from the yoke, to which the bucket is suspended.

The drawing shows a vertical section of a semi-automatic scales for loose bodies.

Receiving hopper / scales for loose bodies has a bottom 72, in which sector cuts are made. The bottom of the receiving funnel is provided with a flap 20, which is able to rotate with the axis 3 perpendicular to the bottom plane and close the sector cuts in the bottom of the funnel with a corresponding rotation. Axis 3, rigidly connected to the flap 20, carries at its upper end a pulley 2, which is wrapped around a cable 22, slung over blocks 14 and carrying on a free

the end of the load 19. A slider 4 is placed on the cable 22, resting on the latches .5 and 6, which, having thrown back, enable the slider 4 to move right, in the direction of the load 19. The cable 22, when moving, winding off the pulley 2, will cause the axis 3 to turn, and therefore the flap 20 at some angle. The handle / 5, suspended from the end 23 of the cable, serves to rotate the entire system in the opposite direction. By means of special earrings, 24 unequal arms of the rocker arm are suspended to the charging hopper by 9 weights, to which the bucket J6 is suspended on their short arm. The long arm of the rocker carries the load / f8. To create normal working conditions for the scales, regular JO prisms and pillows 7 / are arranged.

The loose body from the charging hopper 7 through the above-mentioned sector cuts in the bottom of the funnel enters the bucket 7d, and the rocker arm 9 will begin to rotate, and its end carrying the weight J8 will go up.

The scales are designed in such a way that before the end of the bucket filling, the rocker with the help of the rod 8 will turn a lever 7 at some angle, due to

then the latch 5 is released, and the slider 4 under the influence of the load / P will move to the right until it stops at the latch 6. This movement of the slider will cause the valve 20 to rotate through a certain angle, and the sector cuts in the bottom of the funnel will be half closed. This moment is the first departure. Bulk, continuing to enter the bucket through the open part of the sector cuts, will smoothly fill it. When the bucket is completely filled as a result of turning the lever / at another angle, the latch 6 will also be free and the second compartment will occur. Sector cuts will turn out to be completely closed by valve 20, and in the bucket / b there will be a predetermined amount of loose material. By moving the load 78, scales in a known range can be adjusted to any weight. To unload the bucket, just open the bolt / 7. By using the handle J5 and the cable 23, the entire system is restored to its original state, the sector cuts in the bottom of the funnel are opened and the whole process is repeated as described above.

Bulk flowing through open sector cuts, reports some

acceleration down the weighing bucket, which can affect the weighing accuracy. Cover the slit half-way with the slits in the bottom of the funnel, at the end of the weighing allow the bucket to calm down and smoothly approach the moment of full filling, which causes the device of the two compartments, which is favorably reflected on the accuracy of weighing.

The subject matter of the invention.

Semi-automatic scales for loose bodies, consisting of a rocker arm with a ladle suspended from it and equipped with a valve of the charging hopper held in the open position by means of latches, characterized in that for automatic closing of the valve. T9 load is applied, connected with cable / 2, thrown over blocks J4 with pulley 2 of shutter 20, made in the form of sectors, and to hold this shutter in the open position, slider 4 and resting on latches 5 and b is placed on the same cable from rocker arms.
