Abstract

A delay system for a stirring machine includes a plurality of vertical stirring augers, supported to a cross tube, with each auger having a tilt switch. A gear motor is connected to the cross tube and moves the cross tube forwardly around a bin. A delay assembly is connected to the tilt switches and the gear motor. The delay assembly shuts off the gear motor when the stirring augers are vertically displaced and starts the gear motor after a time delay once the stirring augers return to a vertical position.

First claim

What is claimed is:

1. A delay system for a stirring machine comprising:
a plurality of stirring augers supported by a cross tube and having a tilt switch;
a gear motor connected to the cross tube; and
a delay assembly connected to the gear motor and the tilt switch, wherein the delay assembly is configured to delay forward movement of the cross tube after the stirring augers have returned to a near vertical position.

2. The delay system of claim 1 wherein the tilt switch is configured to send a signal to the delay assembly when the tilt switch detects a vertical displacement of the stirring auger such that forward movement of the cross tube is stopped.

3. The system of claim 1 wherein the delay assembly includes a circuit board and a timer within a housing.

4. The system of claim 3 wherein at least one diagnostic light and an override switch are attached to an outer surface of the housing and connected to the circuit board.

5. The system of claim 1 further comprising the delay assembly having an alarm, wherein the alarm is configured to activate if the stirring auger does not return to a near vertical position within an adjustable predetermined amount of time.

6. The system of claim 1 wherein the tilt switch sends a signal to a timer that shuts off power to the gear motor for a predetermined amount of time.

7. The system of claim 1 wherein the delay assembly is wirelessly connected to the gear motor and tilt switch.

8. The system of claim 1 wherein the delay assembly is configured to shut off power to the stirring augers after a predetermined amount of time.

9. A delay system for a stirring machine comprising:
a plurality of stirring augers supported by a cross tube and having a tilt switch;
a gear motor connected to the cross tube;
a delay assembly connected to the gear motor and the tilt switch;
wherein the tilt switch is configured to send a signal to the delay assembly when the tilt switch detects a vertical displacement of the stirring auger such that forward movement of the cross tube is stopped; and
wherein the delay assembly is configured to shut off power to the stirring augers if the stirring auger does not return to a near vertical position within an adjustable predetermined amount of time.
