Electric Wheel Barrel-Snow Plow
New Winter project!
Found an electric wheel barrel in the dumpster behind my store.
2 larger drive wheels and a smaller bogie wheel.
(Dual motors for posi-traction)
Motors engage with handlebar lever.
I traced problems to a dead 12V 22Ah SLA and a faulty 40A relay.
Replaced relay and tested with 3sRC LiPo but was disappointed at the 2 mph top speed.
Fun begins ...
At 1st I considered running at 4s for a near 3mph but ... too simple and limited.
So, Why not run at 22.2V (6s 14p 22.2V 30.24Ah fits nicely!) with a pot controlled brush controller.
Will maintain handlebar oem relay function or replace with controller on\off circuit?
Variable <1mph - >3mph
Now ... I don't have much use for a wheel barrel, but adding a plow to the front would be a great snow moving utensil!
Torque and speed should be appropriate.
Just have to add some weight. Sand or bags of salt? ... Rated for 200lb loads.
Mount rear 2 wheeled platform for standing on and cruising, with load, down the street.
Upper (green potion) removable by screws or add sideboards to upper portion ...
Battery compartment and motors-drivetrains remove as single component for alternate use!
Replaced heavy SLA with 3s12p Sony LiPo.
12V 22Ah SLA upgraded to 11.1V 25.92Ah LiPo.
Built from 3s2p packs with all cells equal after initial balance last year.
I built a 5-30V LED volt meter with standard 12V DC charger plug for monitoring voltage through charging port.
"Donated" to local food pantry and hauled a dozen loads of topsoil with a 25% drop in voltage.
Rebuilding their Community Garden. Many wooden "raised beds" rotting after 8 years of service.
I've been redesigning and rebuilding with 8" cement blocks. Should last for decades-lifetimes with minimal maintenance!
Holes in blocks should make excellent "pots" for various flowers, herbs, small plants.
Marigolds and petunias repel most harmful insects, found some dwarf Dill that is even more effective, might have to prune-harvest continually. Started ♫ Parsley, Sage, Rosemary and Thyme ♫ as well as Oregano, Basil, Lemon Balm for 6" x 6" x 8" holes ... with good soil. Lined block holes in 3rd and 4th beds with tar paper to slow evaporation through blocks. And, hopefully Lime based cement blocks will deter snails and slugs from climbing into beds.
Charged back up. 8 cubic yards of topsoil being delivered today ...
