  • Page 30: General Operation Theory

    4.3 GENERAL OPERATION THEORY Potatoes are unloaded from transport trucks into the hoppers of the stingers. Here they are carried by chain conveyors up into the hopper of the top belted mainframe conveyor. The chain conveyors are engi- neered to gently vibrate and rotate the potatoes to remove excess dirt.

  • Page 31: Machine Break-In

    4.4 MACHINE BREAK-IN Although there are no operational restrictions on the Conveyor when used for the first time, it is rec- ommended that the following mechanical items be checked: A. When machine is received: 1. Tighten all fasteners. 2. Open breather on gearboxes by turning 1/4 turn.

  • Page 32: Pre-Operation Checklist

    Performing the following pre-operation checklist is important for personal safety as well as for continued mechanical soundness and longevity of your new Mayo conveyor. The checklist should be performed before operating the conveyor and prior to each operation thereafter.

  • Page 33: Controls

    4.6 CONTROLS It is recommended that all operators review this sec- tion of the manual to familiarize themselves with the location and function of all machine controls before starting. Some machines may vary slightly due to custom features but they are similar and all controls are labelled.
  • Page 34 4. Self-Mover Control: Conveyors can be equipped with an optional self- drive feature that allows the operator to move the conveyor slowly within the worksite. Move the control toward the wheel to engage the drive and away from the wheel to disengage. Always install the lock bracket to prevent unintended control movement.

  • Page 35: Machine Preparation

    4.7 MACHINE PREPARATION The machine must be properly prepared prior to us- ing. Before starting machine, be sure that the follow- ing items are appropriate for your machine and oper- ating requirements: Power: Have a licensed electrician provide power at the required voltage, phase and amperage for your machine.
  • Page 36 4. Steering: Conveyors can be equipped with a manual steer- ing system on the front axle unless it has an op- tional steer drive system. Stow the handle in its storage position. Manual An optional hydraulic steering system is available if the unit is designed with a source of pressurized oil.
  • Page 37 An optional over center clamp is available on one end to attach to another Mayo machine. Adjust the hook bolt to obtain the re- quired position. If connecting to equipment made by other manufacturers, connect securely using a chain, straps or other means.

  • Page 41 8. Moving: A. Manual Steering: The conveyor is manually steered and moved in normal conditions. To assist in the moving process, the front wheels are designed to be used for steering. To use this system, follow this procedure: a. Install the manual steering extension bar in its stub holder.
  • Page 42 9. Direct Connect Conveyors: Direct connect conveyors are designed easily to attach together to form a conveyor of any length. Align for straightness and height. Install and move the pin over-center Slide the channel into the bracket and secure with the over-center pin and chain.
  • Page 43 11. Drop Height: Potatoes are sensitive to bruising during the gath- ering, transporting and handling phases of har- vesting. Bruising is kept to a minimum by maintain- ing a full flow of potatoes through each machine and minimizing all drop heights. Bruising during the conveying phase can be minimized by keep- ing the drop height between each piece of convey- ing equipment as small as possible.

  • Page 44: Transport

    • Wrap up and bind to the frame all loose hydrau- lic and electrical ends. Mayo Conveyors are designed to be easily and con- veniently moved from location to location. The term moving is used to describe the action of moving the machine manually and is covered in Section 4.9 Op- erating.

  • Page 60 5.2.4 SPEED REDUCER GEARBOX OIL Each conveyor is driven by an electric motor that is attached to a high ratio speed reducing gearbox to give the required operating speed. Each gearbox is equipped with a drain, level and fill plug. Every 100 hours, the oil level should be checked.
  • Page 61 5.2.5 BREATHER CLEANING Each gearbox is equipped with a breather in the fill plug that vents the internal pressure to atmosphere. As the gearbox temperature increases and decreas- es during the operating and stopped modes, the pressure in the gearbox will increase or decrease if it is not vented to atmosphere.
  • Page 62 5.2.6 CONVEYOR TENSION/ALIGNMENT OR REPLACEMENT Rubber belts or potato chains can be used to move potatoes with the Conveyor. The tension and align- ment of the conveyors should be checked daily to insure proper function. Replace the conveyor when damaged or badly worn. To maintain conveyor, follow this procedure: Place all controls in their OFF or neutral position.
  • Page 63 4. Alignment: a. Conveyor belts: They are properly aligned when the belt runs in the center of the frame panels and the shafts. Be sure to run the con- veyor a full revolution to check the entire belt. the belt can move from side-to-side while it is turning as long as it doesn't contact the sides.
