SU45087A1 - Automatic scales for loose bodies - Google Patents

Description

The proposed automatic scales for granular materials with a vertically suspended not oprokidyvayuschims bucket in order to ensure complete emptying of the bucket and prevent opening of the hopper outlet valves are provided with arm serving as a support for girederzhatel rocker arm which at its rear end acts on the cam roller hopper outlet gates. To keep the bucket in a certain position, until it is completely emptied from the weighed bulk portion, a latch is used, which is tilted towards the tail end of the bucket bottom when the latter is closed.

In FIG. 1 shows a front view of an automatic balance for loose bodies; FIG. 2 is a side view along arrow A of FIG. one; FIG. 3 is the same along arrow 5 of FIG. one.

A bucket 1, standing vertically on two prisms 3 on a horseshoe unequal arm 2, supported by two prisms 3 on the frame of the scale, is suspended from the rocker arm 4 by an earring 5, mounted on a roller b passing through the bucket. The opening of the flaps of the hopper 34 to access the material to be weighed is carried out using the rear end of the rocker arm, on which the cam 10 is supported, mounted on a common roller 9 with the lever 77 for raising the flaps.

The closing of the hopper flaps takes place sequentially using the front part of the rocker arm, as

passing it upwards under the action of filling the bucket. Yoke ,. when reaching the horizontal position, it acts on the retaining lever 12 of the first flap, the passage further, by moving the cam 14 located on the front part of the rocker arm, removes the lever 13 of the second flap, after which the access of the body to be weighed ceases. The rocker, the passage further, and together with it the bite arm 2, connected with the rocker with the help of the earrings 16 and the string 75, with its final part strikes the adjusting screw 17 on the lever 18 of the bottom bucket lock, after which the contents of the bucket fall out. The bottom 21, and with it the tail part of it 20 with a load of 32 ,. tilting the bottom to its original position, become vertical. In order to avoid a quick scoop of the contents of the bucket, in its inner part the bucket is cone-shaped with a quarter-hole of the bucket, and for a slow raining at first, the bottom of the bucket is suspended on a roller 22 located one-third from its edge; while the smaller shoulder of the bottom serves as a brake opening at the beginning.

When the contents of the bucket are emptied, the balance arm is in a horizontal position, the weight located on the girder holder 24, at the moment of release of the bucket, is not down the front part of the rocker arm, and the rear part of the cam tends to raise it, and with it the flaps. To prevent premature opening of the dampers under the weight, a holding device is arranged: a lever 26 rotating on shaft 27, screwed to a post 25, has a cup 25 at one end serving as a support for the lower tempered and core-shaped end of the hyrederder 24 At its other end, the lever 26 engages the latch 30, also put on a roller, fixed to a common rack 28 with the lever 26. The latch 30, by its weight of force, constantly has a slope towards the end of the holding lever 26. Delayed ry At the same time, the chag serves as a regulator of supplementation with the help of the mobile gear on it 5 /. At the moment the bottom of the scoop is closed and under the action of lowering the load located on the bottom arm, under the clamping end of the lever on the latch 30, the retaining lever 26 jumps down, and with it the weight on the hyederholder tends to fall down. and the front part -fig.Z

rocker arm, on which the cam; this opens the flaps, which are held back by the levers 72 and / 3.

All scales are mounted on two interconnected beds. The rocker arm post 55 is connected by two bolts to the bunker resting on the beds.

The subject matter of the invention.

Claims (2)

1. An automatic balance for loose bodies with a vertically suspended non-tilting carpet, characterized by the use of a lever 26, which is used to ensure complete emptying of the bucket and prevent premature opening of the exhaust flaps, which is supported by the support arm 24 of the rocker arm 4, with its rear end working on a piece of a piece of a chamo piece that has a chambered piece. bunker dampers. 2. In the balance of claim 1, application for slits 30, the tail part 20 of the bottom 21, which is deflected to the side when the latter is closed, is designed to hold the bucket in a certain position until it is completely empty from the suspended portion of the flowing material.
