Bin Unloaders

Hopper Style Power Head Bin Unloader
 
It is often difficult to completely clean out a grain bin. Without a grain bin conveyor, grain remains in the bin and contamination can result. Grain remains to be removed after the carriage auger or the under floor drag auger has completed its work. This is especially true of larger bins.

The Twister bin unloader system solves this problem with a custom designed sweep auger. The system works like this:

All grain is drawn down into the under floor auger through a centre hopper, until a reverse cone remains, with no grain in the cone in the middle of the bin and grain remaining which slopes up to a high point at the bin walls. When the centre hopper can no longer draw grain into the under floor auger, the sweep is uncovered by first opening the side hoppers and drawing grain into the under floor auger through these side hoppers. When the side hoppers have created a reverse cone from the remaining grain, the sweep clutch is engaged and the sweep auger begins to circle the bin, drawing grain into the hopper in the centre of the bin, where it is transported out of the bin by the under floor auger.

While the system remains in the bin, it is operated from outside the bin. The powerhead, located outside supplies all of the power for both the under floor auger and the sweep auger. Power can be supplied through flat or inclined powerheads with either electric or hydraulic motors.

The U-Trough Unloading system has a rack and pinion gate, which allows for smooth control of gate opening The gearbox shifter is engaged from outside of the bin, providing a safe and convenient location for the operator to control the equipment. The horizontal powerhead offers the advantage of more capacity, less required power, less maintenance and more economical to purchase and run.

Instead of referring to it as a horizontal powerhead however, we call this our 10" U-Trough Unloading system. In truth there is a horizontal powerhead attached to this unload system, but it comes all as one unit without any need for further assembly.

The powerhead is mounted on wheels and is portable so the same powerhead can be used with a number of different bin unloaders.
This is the most cost effective sweep system on the market. No shovelling and no sweep to carry from bin to bin.

Clean Sweep Unloading
This is a deluxe unload system powered from the outside of the bin. The system works by operating a drag auger under the bin until the grain has been drawn down sufficiently to uncover the sweep. Then the sweep clutch is engaged and the sweep circles the bin to clean out the remaining grain.


Twister's new low maintenance "Hopper Style" power head can be either electrically or hydraulically operated and can be moved from bin to bin.
A bin unloader like this, cleans grain bins efficiently.
Power may be supplied through flat or inclined powerheads with electric or hydraulic motors. The same powerhead may be moved from bin to bin.
