The unique back-up shield and torque tube combination adjusts for close floor clearance to maximize bin cleanup. It removes the grain in one or two revolutions, eliminating the need for an electrical swivel connector. A rubber disc wheel follows the bin perimeter on the sweep end, providing a forward movement and preventing sweep flight contact with the floor. An intermediate bearing stabilizes the sweep flight on 30' (and larger) bins.

The Ultimate in Flexibility

Bin Well Options

Hutchinson’s wide choice of bin wells will fit your method of installation: under an aeration/drying floor, in a pre-formed trench or cast in concrete.

Match any of the well combinations (illustrated here) with the proper length of under-bin tube (8’ thru 25’ ) to make up a basic unloading package for 14’ to 48’ diameter bins. This also may be used beneath flat storage structures.

All bin wells and tubes feature a galvanized or powder coat finish for extended life. Complete the system with an under-bin auger flight with your choice of power heads (shown on back page), slide gate control pipes and our patented Klean Sweep.

Bin Wells with Roller Supported Slide Gate	Intermediate Options	Center Well Options
Center w/ Full-Opening Gate	Band-On Intermediate	Center with Full Gate	Center/Concrete Installation

Band-On Intermediate	Shallow Intermediate	Center with Half Gate	Additional models of Center and Intermediate Wells available.

One motor on the exterior power head operates both unloading auger and bin sweep.

The base unit includes:

• Center power well and roller supported gate with gear boxes
• Bin sweep with back-up shield and reduction wheel
• Under-bin tube & auger
• Appropriate number of intermediate wells with roller supported gates
• Special bin wall flange
• Control Pipe Kit with Lever Opener

Power Heads include Horizontal, 25° Incline or Vertical (shown on back page). Low-Boy power heads are available (in any length between 20' and 50') to return grain to a center pit in circular bin arrangements.

All power heads attach with a square stub to make moving from one bin to another more time-efficient.

The bin sweep, which remains in the bin at all times, is positioned near intermediate wells before filling. To unload, start the unloading auger with sweep clutch disengaged and open center well gate. After gravity flow stops in the center, open intermediate wells. When grain flow stops, shut off motor and engage sweep via separate clutch control rod. Start motor and the sweep will pull grain to the center well while moving around bin. Our Control Pipe and Lever System enhances the operator’s ability to adjust the wells.

Photo 1: The center well is equipped with a double gear box assembly to transmit power from the under-bin auger to the sweep.

Photo 2: Both center and intermediate wells feature exterior gate control. The control pipe and lever system includes pipes that control the clutch and all wells plus outside levers and hardware.

Photo 3: A solid steel clutch with chain transmission is located in a separate enclosure (illustrated). A removable cover provides ready access for lubrication and maintenance.

Units are available pre-assembled. Includes powder coated un-loading tube with intermediate wells welded in place and with gate controls installed.

Note: Cover removed for illustration.

Even in smaller bins we recommend consideration of this series. Job application and anticipated usage level should be your guide in selection. Select from horizontal, 25° incline and unique double-drive vertical power heads shown on back page.

Photo 1: The Klean Sweep drive consists of a heavy duty motor mount and a cast aluminum housing, enclosing the chain and sprockets in oil.

Photo 2: Klean Sweeps for 48' and larger bins include a sweep carrier assembly for extra support of flight & shield. Two carriers for 90' and larger.

Photo 3: Rack & pinion slide gate controls operate center or intermediate wells with the change of a pin. We recommend using our factory-made control pipe kits to complete the job.

Photo 4 & 5: Bin wells have 1/4" plate steel gates supported by rollers; Gates slide into chambers protected from grain weight. May be used under suspended floor, in a trench or cast in concrete.
