Title: Agricultural Engineering


1
Agricultural Engineering
  • Agriscience

2
Careers In Agricultural Engineering
Ag. Safety Engineer
3
Careers In Agricultural Engineering
  • Engineering Careers
  • Designers
  • Four year degrees (B.S)
  • Mechanical Careers
  • Operators
  • Majority are two year degrees
  • Education varies with the type of working
    conditions

4
Safety
  • Objective
  • Interpret personal safety hazards related to
    careers and work in the field of agricultural
    engineering

5
Safety
  • 50 of all farm related accidents involve working
    with machinery
  • The definition of safety
  • Developing an environment free from danger, risk,
    or injury
  • Impossible to accomplish
  • The 1 key to shop safety is the people who use
    it!

6
Principles of Safety
  1. Keep the shop clean
  2. Prevents tripping and related injury
  3. Remove unnecessary hazards
  4. Example- oily rags
  5. Make sure all safety shields are in place
  6. Do not use broken equipment

7
Principles of Safety
  • Wear appropriate protective clothing and devices
  • Safety glasses and goggles to protect against
    dust and flying objects
  • Steel toed shoes
  • Ear plugs where noise exceeds 90dB (decibels)

8
Equipment and Tool Safety
  • Hammers
  • Make sure the handle of the hammer fits tightly
    on the head
  • Do not strike a hard steel surface with a steel
    hammer (ex hammer vs. hammer)
  • Always wear safety glasses
  • Discard a hammer with a chipped or mushroomed
    face
  • Replace loose or cracked handles
  • Discard hammers with cracked claws or eye sections

9
Portable Circular Saw
  • Keep the fingers away from the trigger when
    carrying the saw
  • Do not wedge the guard in the open position
  • The blade rotates at a very high speed
  • never place on a surface before the blade stops
  • Prevent Kickback
  • Do not start the saw with the blade touching the
    stock (wood)

10
Safety Color Coding
  • Development
  • National organizations worked together
  • American Society of Agricultural Engineers
  • Safety Committee Of the American Vocational
    Association

11
Safety Color Coding
  • Red
  • Areas of danger
  • Safety switches
  • Fire extinguishers
  • Red Danger

12
Safety Color Coding
  • Orange
  • Wheels
  • Levers
  • Knobs
  • Orange Warning

13
Safety Color Coding
  • Yellow
  • Wheels, levers, and knobs that adjust or control
    machines
  • Yellow Caution

14
Safety Color Coding
  • Blue
  • Out of Order
  • Broken shop equipment
  • Blue Information

15
Safety Color Coding
  • Green
  • First Aid
  • Safety Equipment
  • Green Safety

16
Fire Hazards
  • The Fire Triangle
  • Components necessary for a fire to take place
  • Fuel
  • Any combustible material that will burn
  • Heat
  • Most material will burn if they are made hot
  • Oxygen
  • Gas in the air that is not a fuel but must be
    present for material to burn

17
Fire Hazards
  • Fire Prevention
  • Take away one of the components of the fuel
    triangle
  • Fire will stop or will not start
  • Safe storage of fuels
  • Clean shop facilities

18
Fire Extinguishers
  • Know the kind of fire
  • Class A- Ordinary combustibles
  • paper, wood, cloth
  • Class B- Fuel fires
  • gas, oil
  • Class C- Electrical fires
  • Class D- Combustible metals

19
Fire Extinguishers
20
Fire Extinguishers
  • Smothering a fire
  • Best used of a person whose clothes are on fire
  • Wrap the person in a blanket to cut off the
    oxygen to the fire

21
Planning An Agricultural Project
  • Blueprints are used to plan projects
  • Simple designs
  • Sharp lead pencil with an eraser
  • Protractor
  • Ruler (12)
  • Compass

22
Planning An Agricultural Project
  • Detailed plans
  • Drawing board to attach paper
  • Masking tape
  • T square for drawing horizontal lines
  • Right triangle for vertical lines
  • Scale
  • Instrument with increments shortened according to
    proportion
  • Flat scale- looks like a ruler
  • Triangular scale- three sided, but 6 scales

23
Planning An Agricultural Project
  • The basics of drawings
  • Sketch
  • Rough drawing with no demensions
  • Pictorial drawing
  • Shows all three views
  • Top
  • Side or end
  • Front

24
Planning An Agricultural Project
25
Planning An Agricultural Project
  • The basics of drawings (continued)
  • A scale drawing represents objects in exact
    proportions
  • If the scale is ¼1 then ¼ on the drawing
    would equal 1 foot on the object
  • So. A 2 line on the drawing would equal what on
    the object?
  • 8 feet
  • Scale will vary depending on the size of the
    object

26
Class Assignment Your group will construct a 6
foot picnic table using the materials
provided. Your grade will depend on how well you
follow the blueprint and how well you complete
the project.
27
Planning An Agricultural Project
  • Determining Materials
  • Bill of material
  • List and description of materials needed to
    complete a project
  • BF board foot

28
Board Feet
  • Thickness (inches) X Width (inches) Length (feet)
  • 12
  • How many board feet are in a board 1 X 12 X 8?
  • 1 X 12 X 8
  • 12

BF
29
Board Feet
  • Assignment
  • Calculate the board feet required to build our
    class project
  • (24) 2X6X12
  • (4) 2X6X10
  • (8) 2X4X10
