SU45088A1 - Automatic scales with vertically suspended swing bucket divided into two parts - Google Patents

Description

In the proposed automatic scales with a vertically suspended swinging bucket, divided into two parts, in order to keep the bucket from orbit until the balance arm equilibrates, as well as to direct the flow of the loose material into one or another branch of the bucket, the latter is equipped with a bracket fixed to it, articulated with bunker plug. In order to free the corresponding part of the bucket from a weighed portion of the loose, on the bucket there are reinforced rollers, which, when the bucket is turned, act on the shaped levers articulated with the exhaust flaps of the bucket.

The drawing shows a front view of an automatic balance with a vertically suspended swinging bucket divided into two parts.

On frame 7, a bracket 4 is fixed, carrying a prism 16, on which an equal shoulder arm 2 rests. At one end of the rocker arm a hanging holder 14 is suspended, and at the other end, on a suspension bracket J9, a bucket P divided into two equal compartments A and B.

The bucket 9 below is supported by a prism 29 located at the end of the suspension / P. When the position of the bucket shown in the drawing, the bulk flowing into the hopper 3, pass through the passage gap 8 into the compartment A of the bucket 9, and

the bracket 5 is on the right side of the stop stopper 7 and, as the bucket 9 is loaded, on which the bracket 5 is strengthened, the latter decreases and at the time of accurate weighing passes below the stop stopper 7. The swing bucket s on the prism 29 poured onto the left side and the roller The / J mounted on the bucket 9 rolls down to the end of the cross 72 attached to the suspension / 9 release the pressure lever // from the pressure, and the bucket gate 22 opens to unload the corresponding part of the bucket.

The bucket 9, at the moment of a full plumb, turning from the right side to the left, leads bracket 5, articulated with a plug W, which is simultaneously a damper - closes the passage gap on the left side and guides the flow of the loose into the right compartment B of the bucket 9. During unloading the bucket, the valve 22 is open and the shaped lever 77 is in a raised position (shown on the right side of the bucket), but having a large discharge capacity against loading, the bucket is released before the full load of the other part of the bucket and the gate 22 is counterbalanced by 20 closures The lever 77 is positioned as shown on the left side of the bucket.

With; the full load of the compartment D of the bucket 9, the roller 75 of the compartment B rests on the lever / 7, which prevents the opening of the shutter 22 of the compartment B, and the roller 75 on the compartment A rolls down to the end of the cross plate 72 and prevents further movement of the bucket 9.

The stop stopper 7, reinforced at the bed 7, has a regulating screw with a nut b; By turning the nut, the stop stop 7 adjusts the accuracy of the plumb line.

Before checking the weights, the locking hook 27 is placed on the roller 75 and the inclination of the bucket 9, delaying the movement of the roller, which continues to press the lever 77, holds the plug W in the center of the opening of the valve 24, which closes the gap 10 and stops the grain flow until the end of the test.

When the grain remains in the bunker that does not fill the bucket to a certain weight, or if you wish to check the accuracy of the plumb, the bracket 25 is deflected; then, the division lever 77, which lies at one end on the prism 30 located on the bracket 57, is supported by the prism 52 on the plate 75 fastened on the bearer M, and the amount of residue is determined by the movement of the load 27, and the accuracy of the balance is determined. Scale 28 divided by

strengthened at the end of the rocker arm 2, serves to settle the exact plumb line.

A hectare 25, reinforced between the end of the suspension J9 and the bed 7, serves to resist horizontal swinging of the bucket.

Locking levers / 7 and bucket shutters 22 to prevent wear, due to their frequent movement, must be placed on ball bearings 27.

The subject matter of the invention.

Claims (2)

1. Automatic scales with a vertically suspended swinging bucket, divided into two parts, differing in the use of a bracket 5 fixed to the bucket, coupled with a fork / O valve 24 and intended both to keep the bucket from turning until the balance of the rocker equilibrates, and to direct the flow in one or another branch of the bucket. 2. In the weights of claim 1, use rollers 75 fixed on the bucket, intended to act upon turning the bucket onto the shaped bars 77, articulated with the outlet buckets 22 of the bucket, in order to release the corresponding part of the bucket from the weighed portion of the loose.
