Baler Recap

What are the two types of round balers?

• Variable Chamber / Fixed Chamber
• Changeable Chamber / Fixed Chamber
• Belt Chamber / Roller Chamber

Advantages of round balers?

• Movable downhill with minimal effort
• Infinite amount of bale sizes
• Easy stacking, handling, wrapping, storage

Bale density means

• Bale weight
• Round bale
• Bale size

How is the bale formed in a fixed chamber baler?

• Enters the chamber and a series of fixed rollers allow the bale to be compacted and formed 
• A series of belts allow the formation of the bale
• A pre-chamber forms the slice, which allows it to form a bale

How is a fixed chamber baler and a variable chamber baler different?

• Fixed chamber uses rollers and a variable chamber uses belts
• Fixed chamber uses belts and variable uses rollers

How is a bale formed in a variable chamber baler?

• The concave allows for the compression of the bale
• Uses endless belts to compress the bale
• The silage is already compacted and could be formed into any shape by the compactor

Identify the component not on this baler

• Pre-compression rolls
• Twin endless belts
• Starter roll
• Fluted start roller

Name 4 stages of bale wrapping in order of operation

• 1. Completed bale guided from the chamber

  2. Bale on the wrapping table 3. Wrapping arms begin to wrap plastic film

  4. Wrapped bale discharged
  

• 1. Wrapped bale discharged  

  2. Bale on the wrapping table

  3. Wrapping arms begin to wrap plastic film 4.Completed bale guided from the chamber
  

• 1. Wrapping arms begin to wrap the plastic film 

  2. Wrapped bale discharged 

  3. Bale on the wrapping table wrap plastic film

  4. Wrapped bale discharged  
  

Two safety or machine protection devices on a round baler?

• Slip Clutch/ Hydraulic Density Protection Springs
• Knife Sharpener/ Knife Cover
• Star Cover/ Compression Rollers

Two disadvantages of a variable chamber round baler?

• Badly shaped bales can be made/ Belts can perish
• Bales can be made too small or too big and damage the baler
• Very complex system/ Very hard to maintain.
