Front hopper build

Good outcome. How big a job would it be to swop the motor kit from one drill to another eg from say a rape drill to a cereal set up. Could you leave all wiring etc connected and swop it over reasonable or is there other issues I,m not seeing.

Got a couple of hours this morning to start fitting the external pipe work to my hopper . I’m going to tack it all together and then a friend of my is going to tig weld it .

That looks real tidy, But I did the same on a hopper I made some years ago almost identical design of metering and pipes etc but I found it choked the fert in pipe as the bend was too close to the metering unit and stopped the material getting into suspension in the airflow. The guy I was drilling for at the time ran a blower lorry and reckoned he needed a straight section of pipe after Venturi to get the material airborne which proved to be correct as I went back to flexi pipe from Venturi which gave a very gentle curve and never another issue but hard corners did not work for me so beware before you spend too much money on stainless pipe etc. ( looks the biz though)

Not sure how critical it is but keeping those shafts straighter would be something I’d Look at to regulate flow.

It amazes me to see the speed variations as it ran.
The two yokes cancel eachother out as long at they make the same angle. So if the input and output shaft are parallel you are good.
I cannot see for the rubber surroundings but if they are cv joints it doesn't matter anyway.

The issue and the reason that CV joints are used is due to the acceleration and deceleration in the shaft, the speed at different points in the rotation differ, even though as you say the angles cancel out. It doesn't really matter for PTO that there is a slight acceleration and deceleration of the shaft in one revolution, but for something like a vehicle with wheels in hard contact with the ground it does.

Top job, looks amazing, nice one. Dare I ask how much it stands you to? So the million dollar question what would you differently next time?

cheers

Thanks Alistair, not including my time it has cost just under 10k . I haven’t found anything that I would change yet , I’m really pleased with the side mounted Venturis as they make calibration so easy and it’s nice to have all the pipe work external.also the new touch screen Artimis is nice to use .

The front unit on the Weaving is fine, but the back one is a pain, so yours sounds good.

Have to say Robert you are wasted as a farmer, engineering is your forte also. With a front tank you have a drill for every occassion. (y)

Bob , with two motors , is the box capable of running motor speeds at different speeds , so one running seed ,and other putting tsp down on variable rate 🤔
Full fat RDS Artemis can run 2 or more if required. They're calibrated independently so run at whatever speeds needed to output the rate you want.

RDS lite can only run 1 motor.
