SU68733A1 - Scales for weighing loose bodies - Google Patents

Description

The invention relates to semi-automatic scales and is intended for mechanized weighing of cement before loading into a concrete mixer.

A distinctive feature of the proposed weights is the design of the intake and exhaust valves, made in the form of two rows of curtains connected by levers.

FIG. I shows an external view of the scales, and FIG. 2 - cross section.

The upper row of curtains / (inlet valve) is opened by turning the handle A. Cement from the hopper is poured into the weighing box //, suspended on the weight beam G.

The yoke G is equipped with a mobile load D and a weight scale, as on conventional lever weights.

The lower row of shutters /// (discharge gate) is in the closed position when the cement is loaded (Fig. 2).

Under the action of the weight of the cement, the lower blinds tend to open, but this is prevented by a stop bar B, which at one end is pivotally connected to the balance beam D and the other rests against the slot.

disk B, mounted on the axis of the curtain.

When the weight of the cement poured into the box of the balance reaches a predetermined value, the weight arm G slightly rises, so that the stop bar B comes out of the slot of disk B, the disk rotates, the lower curtains open and the cement begins to pour out of the balance. When opening the lower curtains ///, the upper curtains / associated with the lower bars E are closed and the further loading of the cement into the scales will stop.

For the next weighing, turning the knob A again opens the upper row of curtains /. Thanks to the linkage E, the lower row of curtains /// is closed by the same rotation of the handle and the stop bar B will enter the slot of disk B.

In this position (shown in Fig. 2), the cement again fills the weight box.
