Description

An automatic balance is known for bulk solids, consisting of two vessels alternately filled with bulk solids, and equipped with a load that slides along the rocker arm. In the proposed Hesas, for the d / alternate filling of the bulk into the vessels, a device of two discs is used, slidably fixed on the shaft of the throw-over gate and alternately included in the clutch with. teeth of traction wire. A device consisting of rods, connected with the help of crank bearings with scarlet of the gate and with its end resting on the corresponding projections of the rocker arms was applied from tilting the rocker arms.

In FIG. 1 is a front view of a scale; FIG. 2 is a section along the line AB in FIG. 3; FIG. 3 - vertical section of the scales.

The yoke / balance (fzg. 1-3) is equipped with two vessels 2, which serve to fill them with a free-flowing substance. Above vessel 2, bunker 3 with sleeves 4 w is strengthened. 5 / when the flow through to one or the other sleeve is regulated by a throw gate b,

A device consisting of two discs 10, a collar, mounted on the shaft of the gate 6, was used to alternately fill the vessels 2 in bulk.

and alternately activated by electromagnets 9 & adhesion to the tooth; Chats 11 transmission drive.

The tilting of the rocker arms / is carried out by means of a device consisting of rods 12 connected by cranks with the shaft of the gate 6 and its lower end abutting against the corresponding protrusions 13 of the rocker arms.

When under the weight of a substance 2, the rocker / comes into balance, the roller 7 fixed on the scale arrow closes contacts 8.8, resulting in electromagnets 9 located on one side of the gate 6, npHTHHjTT disk 70 slidably fixed on the gate shaft 6 and provided on its flat side with oblique teeth for coupling to the gear // gear drive. In this way, the gate 6 will turn and allow the flow of loose material to another vessel. Simultaneously with the rotation of the shaft of the gate, the rod 12 connected to it by means of the crank will strike the arm of the rocker arm 13 with its lower end and, removing it from the equilibrium state, will cause the load to slide to the other side, after which the operation of the scales continues as described above.

Subject, invented.

1. Automatic scales for loose bodies, consisting of two f vessels alternately filled with bulk materials, equipped with a load that slides along the rocker arm, differing in that a device consisting of two discs is used for alternately filling into the bulk vessels,

Slide a cross-mounted gate b fixed on the shaft and alternately turned on by means of electromagnets 9 in decanting with gear // gear drive. 2 In the weights of claim 1, the use of a tool for tilting the rocker arm, consisting of rods / 2, connected by means of cranks to the shaft of the gate 6 and its lower end resting on the respective protrusions 13 of the rocker arms.
