A&K DEVELOPMENT 30" OR 36" WIDE DISTRIBUTION BELT CONVEYING SYSTEM FOR HUSKERS AND PRE-CLEANERS

System is specially designed to gravity feed multiple "Power Huskers" or "Pre-Cleaners." This unit is equipped with a properly sized electric motor, chain driven and gear reducer.

The belt of the conveyor is constructed with a "C" section v-guide on the underside for positive tracking, white food grade belting. Weighted shears for feeding to stainless steel hoppers. Modular angle mounted conveyor bed is constructed of stainless steel. Conveyor bed rail are stripped with UHMW material, to reduce the belt drag. Pulleys are constructed of stainless steel, plus lagged drive pulley. Included in the system is support structure, which mounts to the shaker feed framework and hoppers.

AIR POWER SHEAR SYSTEM

This Automated “Power Shear” Feed System is Accomplished by Use of the Following Hardware and Software:

• A tilt bed feed conveyor as commonly used in the industry with weighted shears.
• Pneumatic powered shears replacing the weighted shears.
• Product reservoir hoppers as commonly used now including an infrared sensing device.
• Control box including a programmable controller with a specially designed program. Also, included are manual override toggle switches.

How the A&K Development “Power Shear” System Operates:

• When started, the tilt bed conveyor activates the automatic feed system control through an electrical interlock, normally open auxiliary contacts on conveyor motor starter, turning the system on.
• A specially designed software program in the programmable controller controls each individual shear by both an elapsed time function or product depth in the reservoir hopper, as detected by the infrared diverging beam sensor.
• Shears are programmed to cycle starting with the nearest hopper to the supply point, and then cycling based on a time function to each hopper in succession until the furthest hopper has been supplied. Note: This cycle can also function in reverse if desired. The cycle then repeats as many times as necessary based on the time function, until such time that product depth in the hopper activates the sensor and it then takes over control of the shear. Any hopper showing sensor satisfied based on product depth will be skipped in the cycle. Once all sensors are satisfied, indicating system full, the infeed conveying/elevating system will be shut down. After an adjustable time delay when system full is achieved, an indicator light on the control box face is turned on. Another light in parallel should be mounted within sight of the truck unloading area. As soon as any of the hopper sensors again call for product, the system infeed will be re-started after an adjustable time delay and the system full indicator light is turned off.
• The programmable controller can further be programmed to control the speed of the metering conveyors within the range of maximum speed the operator selects. Based on the information received at the programmable controller from the hopper sensors, the speed of the metering conveyors will automatically be adjusted downward or upward based on how many hoppers have an adequate supply of product. For example, when the line is first started, the metering conveyors will automatically be run at the lowest speed until a selected number of hoppers become full. The speed of the conveyors will then be increased automatically to the selected maximum speed. This ensures all the husking machines are worked equally and dropping corn on corn when filling the hoppers minimizes product damage.

Advantages of Using the A&K “Power Shear” System

• System supply can be un-metered as this system is capable of operating successfully with great variations in volume of the product supply.
• All husking units from the first in line to the last become productive very quickly after start-up, due to the fact that the time function control of the shears feeds a small amount of product to each hopper before completely filling any.
• No merry-go-round or overflow system is necessary as the infeed supply is automatically turned off when system is full, and automatically restarted as necessary.
• No manual labor is required. Note: In the past all husking systems have been designed to utilize a person with their primary function being to oversee and assist the distribution system in equally distributing product to all the huskers. With the automated feed system, manual assistance is no longer required. Therefore, personnel can be used at a different physical level within the husking building to much greater advantage.
• The fully automated husker feed system provides even distribution of product to all huskers easily and with great dependability. This system can be retrofit to any existing tilt bed conveyor.

BIG BIN SYSTEM FOR RECEIVING, HOLDING, METERING RAW PRODUCT

This bin is specially designed to receive and meter raw product. Can be used to quickly unload and store a complete truck load of product or approximately 22 to 25 ton. This can be achieved in approximately 4 minutes. The speed of the draper belts can be decreased to meter and feed at plant flow rate. The bin supports and transports the product by use of dual six foot wide belts, the belts are supported and driven by rollers all along the bins length. The drive consists of 4 qty. shaft mounted gear box drives, 2 hp. 60 cycle.

Framework, roller bed, pulleys and support structure are constructed of mild steel, epoxy coated, with galvanized sheet metal side walls. For shipping convenience the bin is shipped as sub-assemblies, final assembly at customers location. Bin is 40 ft. long and 14 ft. wide. Electrical control panel including A.C. variable speed controller, all control switches, and safety warning horn by use of a programmable controller.

48”/36” WIDE PAN RECEIVING VIBRATORY FOR RAW PRODUCT

This is a mechanical vibratory conveyor, constructed of extra heavy mild steel pan, framework and dump backboard. The system is equipped with a properly sized electric motor which drives a positive eccentric drive. Also, includes steel support frame for concrete base support and mounting.

Approx. Length of Pan:

• 36 Feet or 11.0 Meters
• 40 Feet or 12.2 Meters
• 50 Feet or 15.3 Meters

50 DEGREE LEV-FLOW ELEVATOR

This unit is equipped with a properly sized electric motor, chain driven to mounted gear reducer. The special elevator belt has three inch high molded cleats staggered on twelve inch centers. The elevator bed frame is constructed of mild steel, painted, polyurethane paint. The elevator belt is set at a 50 degree angle to assure proper metering of product. The elevator bed is stripped with UHMW strips to reduce the belt drag. The support frame is included. This unit also includes a converging beam sensor for controlling the level of product and the Infeed Hopper. (A.C. variable speed controller not included).
