pto driven vacum kit?

[Iplayfarmer]

I just thought of this too... You could build your suction unit to take a standard furnace filter. The low efficiency filters would be plenty adequate for your needs, and they are cheap.

I also thought of building something like this.......a company I know just scrapped out big industrial fan/blowers (kinda like a hampster wheel).....

IIRC they were driven by 20 to 50 hp elec motors.....

would have required some kind of vbelt or serpentine belt pullet setup to up the rpms if driven off the PTO......these were around 1700 rpm.....

They were offered to me but hated to see them go to the scrap man.....

I don't believe you are going to get the kind of suction you need from those squirrel cage blowers. Put your hand in front of your air condition intake duct and feel the suction. Not much there.

Those large blowers/vacuum on the back of tractors or those that have their own engines, either have large blades, or the smaller blades turn at a higher rpm. The impeller on the Trac-Vac, are about 4 in wide, and the diameter is about 18 to 20 in, and they turn at around 3600 rpm. The blades also have to be thick, like 1/4 in, and even then, the tips of the impeller have been bent.

I wish you luck on those fan assembly's, but don't expect much.

BBogen,
Have you ever seen a cyclone dust collector? Oneida Air Systems - Dust Deputy or 2HP TEMPEST Cyclone Dust Collector: 12" Steel Impeller and Filter Filter Bag at Penn State Industries Same principle here, you get the debris into smallish pieces with the MMM, suck them into a cyclone separator & they slow down to drop into your box. The biggest trick is getting enough air moving to make it work. Most homebuilt cyclones use squirrel cages from furnaces. Theyæ±*e cheap, effective and reasonably easy to get a hold of. I知 thinking of something similar for my BX22, using a pull behind lawn cart, (Agrifab from the Borg), with a box built to fit inside the bed, with the PTO attached to a pulley to spin the Squirrel cage with a belt. Take a hose from the MMM to the Cyclone & another hose from the cyclone to the Squirrel cage. Possibly vent the Squirrel cage back to the MMM on the closed side with a hole/slot cut opposite the discharge side. I think some 6-8 black corrugated pipe would work. There isn稚 a lot of 天acuum there is a lot of moving air 650cuftmin as a minimum. Different kind of suction. HTH

T-Man.

air from a single intake duct is being divided from multi intake ducts.

if / when i take off the door to squirrel cage blower for this house or another. and the fan is on. i best watch out for any loose clothing or making sure i have good grasp on the door. due to door wanting to pull out of my hands. motors being any were from 1/2 hp to 1.5hp. that are running the blowers you might find in a furnace or central A/C unit.

what blows out of them. has to come from some were at the same speed and amount. when counting up everything that the air gets divided into, to blow and suck air throughout the house.

i believe ya, about fan blades getting bent up. at the speeds they rotate, just the right size bang from a stick, rock, or other. and something has to give. and most likely be torn up.

i am trying to avoid any type of mower, rear end, mid mount, or front. granted it would be nice to add some sort of end to end of hose and go back across lawn and get the old cut grass off. i just don't like idea of the vaccum fan and stuff going through the fan blades.

as far as cyclone separator. in ponding and dealing with fish waste water it would be known as a settling chamber. same basic principles apply. if folks used a 55 gallon drum or garbage can. the inlet/outlet on them would most likely be a good thing to copy.

but for the FEL or a plywood box container. its more of relying on speed of material slowing far enough down to fall down. when it hits the container were air movement through it becomes slower. i am going to assume. a baffle might be needed to cause things to slow down quicker and cause abrupt change in direction of air flow. so more grass and lighter stuff falls out of the air current in side box shape containers.

hhmmsss i don't see why not. though i might encourage some chicken wire between the furnace filter and fan. so if something happens, (bumps, clogging) the filter doesn't end up lodged and stuck pretty good in the fan.

i haven't figured anything out yet, of what i have on hand already. to connect pto shaft to one or both furnace blowers. i am hoping i might find something once i get the grain bin turned into a shed. and start sorting through things.

Furnace blowers wont work. They move a lot of air, but to do so must have very large pipes because they can only develop an extremely small pressure differential. -- Therefore low velocity flow. It wont move solids thru a pipe.

An old grain blower would be a better choice. They move air at a higher velocity and are very strong. Have found them for very little money in scrap yards and all you would have to do is some work on to get them up and running and attach your hose and some sort of container. Have seen some that the blades are only made of thick rubber spinning in a 4' drum maybe 6" to 8" wide. If you can't find one cheap.... you could always bild your own out of an old fuel barel.... These things blow grain 30' to 40' into the top of bins this should be enough air moving to be a good vac.
Good idea!!!! got ME thinking now.
:thumbsup:

Don't bother with a furnace fan. They are rated for less than 1" of static pressure. What you need is a high pressure blower capable of 8-10" of static pressure. Also, high pressure blowers such as in a dust collector keep the air velocity very high as well to transfer the material. Keeping rocks and other debris out of the fan is very simple with out using a filter. A relatively large settling box or tank will need to be installed before the fan. As dense material goes into the tank, the velocity slows to a point at which gravity has a chance to take over. This way only very light materials actually go through the fan.

Pull behind tractor vacuums work great with one minor issue, and that is with sticks getting stuck in the hose.
