What is this scheme from?

Question

Electronics

I need the principle of operation of this circuit, maybe someone knows where you can find it or an approximate analogue.

Answer 1

What is the principle of action here? :) Horseradish with two motors. The upper motor according to the scheme rotates some kind of auger. Those. movement of some raw material or product. Button SB2 starts the auger, SB1 stops. The lower motor in the diagram drives the crushers. Crushers work for a specified time (there is a time relay). But we see that they can only be started when the auger is running. So - logically - the auger does not feed the raw material to the crushers, but, on the contrary, takes the already crushed garbage (raw materials, etc.) It is also curious that a simple electric braking circuit for the crusher drive is used - the relay contact group to the left of the lower motor. So the mechanical part requires that the stop occurs quickly. There is no braking circuit on the auger. Basically, that's about all there is to say. Well... the LEDs indicate the operating mode. An ammeter was attached to the crusher. If the mechanics jam, the ammeter will go into the red zone or go off scale. So it is assumed that the operator will sit and control the operation of the device.

Answer 2

Crusher control scheme.
You can find similar schemes in the passport for any machine of the last century. Turning will most likely be simpler, but grinding is more difficult.
