SU28356A1 - Fitting in concrete mixers for signaling the number of batches and transfer to the meter - Google Patents

Description

In the proposed adaptation to concrete mixers for signaling the number of batches and transfer to the counter, the concrete mixer shaft is rotated by means of a detachable coupling coupling, the lower part of which is covered by a hinge collar and is periodically turned off when the pestle hardened on the pestle collapses into the grooves of the cam disc, rotated from the shaft of the concrete mixer . A spring-retracted collar with a rigid rod acts on the lower collar that controls the activation of an audible or light signal on the end of the batch and is connected by a ratchet gear to the counter of the number of batches. For the subsequent commissioning of the concrete mixer and the coupling of the parts of the coupling coupling, the collar covering the lower part of the coupling is connected with a flexible rod controlled by a lever which is under the action of the concrete mixer bucket.

In FIG. 1 shows a vertical section of a fixture in concrete mixers for signaling the number of batches and transmission to the meter; FIG. 2 -, side view; FIG. 3 is a horizontal section through AB; FIG. one.-

In the fixture in the concrete mixer for signaling the number of batches and transfer to the counter, gear / 7, rotating

from the engine shaft,. drives the gear 6, which fits tightly onto the hub / coupling, which rotates freely on the shaft 70 of the concrete mixer. In the latter, on the key, a movable sleeve 2 is mounted with a coupling coupling with teeth, which, when moved along the shaft W, come into contact with the teeth of the sleeve / and the shaft fO, rotated, is supplied to the rotary shaft. during rotation, a worm gear 25, rigidly seated on a platen 29, on which a knuckle disk 27 is fitted, fitted at the ends of the diameter with grooves, one of which passes through its entire width, and the other is only up to the middle. The shaft fO of the concrete mixer rotates until, while the pestle 2 / is moving in the guide post. 20 and connected to the collar 3, swinging on the hinge 78, will not fall into one of the grooves on the cam disc 27. As soon as the pestle 2 / gets into the groove of the disc 27, the spring 24 pulls down the collar D which is connected with the fingers with the sleeve 2, the clutch and disengages it with the ram /, as a result of which the rotation of the shaft 70 is stopped, and the gear 6 continues to rotate.

To the collar 3, by means of a finger 23, a rigid ha ha 23 is attached, which,

when lowering the clamp 3, it pushes the swinging clamp 33, the closing contact of the sound and light signal indicating the concrete is made in the concrete mixer and the end of the kneading. At the same time, the clamp 33 by means of the ratchet pawl 42 acts on the gear 35 of a countable disc counting the number of batches in the concrete mixer. The free end of the yoke 3 is connected with a flexible pull, which envelopes the roller 7, the other end of which is attached to the lever, at the exit yc, under the action of the loading hopper of the concrete mixer. When the material from the bucket is poured out, the bucket acts on the lever that pulls the pull and thereby lifts the yoke 3, which engages the parts 7 and 2 of the coupling and leads; back into rotation. shaft 70 concrete mixer. The kneading time is set by moving the lever 28, equipped with a fork, of the cam disc 27 along the roller 29, whereby the pestle 27 falls into the grooves of the disc and stops the shaft 7 of the concrete mixer either through one turn or through a half turn.

The subject matter of the invention.
