Working Model Grain Elevator, Thresher Amaze Crowds

Working Model Grain Elevator Thresher Amaze Crowds AG WORLD Ag World A few years ago Brian Harvey volunteered to serve on the board of his local agricultural society That led to another volunteer project which quickly became a labor of love and practically an obsession
    Harvey decided to build an educational and interactive display that would increase attendance to the local fair in Swan River Manitoba known as Northwest Round-up held every July
    For the fair s agricultural exhibition called Down on the Farm Harvey designed and built an intricate working model grain elevator which has been wildly popular for the past two years with adults and children alike
    Last year he added an amazing working model 1/3-scale threshing machine This year he s adding a dump truck three grain bins and a self-propelled grain auger All of these items are operated by remote control
    Harvey says he s grateful for the tremendous assistance provided by his brother Jerry daughter Meredith friend Geoff Child and a few other people
    The working models are an ideal way to engage entertain and educate about farming because they re so much fun to operate Jerry says
    The elevator stands about 5 ft tall and all aspects of its operation can be controlled by remote control
     You can start and stop the leg turn the garber spout at the top of the leg open and close the chutes at the bottom of the bins weigh grain and send it to a bin within the elevator or out to a truck or train Brian says There s a cute little G-scale train with an awesome sound card in it and a proper grain car and caboose that sit on a raised track You can load the grain car drive the train onto a trestle that has a hole in it and drive a semi truck underneath Once you drop the grain into the truck you can drive the truck up into the elevator and dump the grain into the front pit
    Harvey says three people at a time are allowed to work the controls One drives the belly dump truck one drives the train and one runs the console on the elevator Then they switch places until they ve all had a turn with each model
    Two computers are involved in the operation of the elevator one of which was built from scratch by friend Geoff Child and is located inside the elevator It converts raw data from the infrared bin sensors and then sends it out to the desktop computer for display
    Harvey also built miniature push brooms and corn brooms that are used to sweep up the mess after the truck has unloaded into the elevator
    In order for people to see into the elevator and learn how it works Harvey left one corner of it open with a scalloped edge
    His daughter Meredith cut and glued on more than 2 300 individual tapered cedar shingles as well as each piece of siding
     The elevator took a little over 2 000 hrs in all to build
    He says the stationary threshing machine required 2 300 hours to build When folded up it s 10 ft long and 3 ft 6 in to the top of the feeder housing
     The thresher puts out grain that a seed cleaner would be proud of Jerry states Everything about it is the same as a real threshing machine but smaller One thing that s different is that it has windows so you can see in to see how it works
    Because these machines are dangerous the brothers demonstrate them inside a fence for 10 minutes at a time and then take down the fence so people can see them up close
    For the first time this year the threshing machine and the elevator demos will be neatly tied together thanks to three bins a dump truck and a self-propelled grain auger that Harvey also designed and built
    Now the thresher dumps grain directly into a holding bin From there the dump truck picks it up and then it s driven over to where the hopper bottom bins are Then the truck empties its box into the self-propelled auger which puts the grain into the hopper bottom bins The semi trailer truck then drives beneath the bin s auger and is filled so it can transport its load to the elevator This is exactly what would happen in a farm situation Brian explains except that today the threshing machine would be a combine
To build the semi and the dump truck Harvey used model truck cabs he purchased and then he made his own more rugged chassis steering wheels and tires This aspect of the system took hundreds of hours
For all of the time that these models have taken to design and build I have to admit that after a 1/2 an hour of watching the grandpas and the young people enjoy it I m paid in full for my effort Jerry says
The response from the business people in Swan River Valley to donate and or help pay for building supplies was tremendous
