I was watching a front-end loader unload some dirt. It was somewhat adherent to the scoop. The operator got it loose by cranking the lever controlling scoop angle back and forth fast to jiggle the scoop. This shook the whole machine and was loud. It got the dirt out, but seemed hard on the machine.
I
propose a small dedicated electric motor could be affixed to the back of the scoop. Its job would be to vibrate. The operator would control it with a button. The scoop would vibrate and the dirt slide loose. It would be easier on the machine. It would work for all manner of excavating equipment, cement mixers and dump trucks too.

a viable accessory to be mounted at the back of the shovel

It would be a wonderful experment to try this at home--in your backyard, that is. [rotary, Jun 16 2009]

That's a really good idea! |
|
| |
You could also use a hydraulic motor. |
|
| |
Vibrating would also cause the blade to push into the dirt easier. [+] |
|
| |
+ nice idea, except when the dirt is wet maybe we could have a small blower attachment to dry it off for easy removal. |
|
| |
+ When I read the title I thought it would be for a hand shovel. (It sounds kind of Star Wars - Vibroshovel!) |
|
| |
I too thought this would be for improved digging... |
|
| |
I thought this could be useful when shoveling your sidewalk. Lots of times wet snow gets stuck to the shovel. |
|
| |
You could rig one of these up with a car starter motor and an offset weight on the axle. You could clamp it onto the blade. A clamp is not a good long term solution for something vibrating but the shovel owners would probably allow you to try this. I am not sure if the starter motor has the rpms for optimal vibration. |

Plastic explosive would get the dirt off quicker. |
|
| |
//Plastic explosive...// would probably put more of a shock into the hydraulics system than you'd want. |
|
| |
aren't those shovels kind of heacy? what sort of force are we talking here, to get a good vibrate going? maybe there is a good reason the hydraulics attched to the simple lever mechanism are so big. nice idea though. |
|
| |
i though you meant it vibrates to help cut the soil. is that another idea? |
|
| |
Or you could keep a huge jar of lube to hand and occasionally dip the scoop into it. |
|
| |
Could have used this a time or two. |
|
| |
//Plastic explosive would get the dirt off quicker//
A reactive shovel you say? Hmmm |
|
| |
Paratroops have often used explosives to create impromptu "trenches" where terrain around the DZ doesn't give adequate cover. |
|
| |
How about a bumper plate between the scoop and the dirt? It wouldn't need much power to vibrate dirt off an empty scoop face |
|
| |
A vibrating shovel would require heavier duty lock washers. |
|
| |
I think some jackhammers have an attachment that is similar to a shovel head. |
|
| |
Hammer drills oscillate back and forth to impact the concrete when driving in masonry drill bits. |
|
| |
Clay spades are pneumatic, hmmm. |
|
| |
What actually is used are teflon or plastic coatings that get the same result, probably cheaper... |
|
| |
Also, one of the main considerations is that you want to decrease the attachment weight in order not to affect your machine tipping load ratio. |
|
| |
I too thought this would be a hand shovel. Having spent all day at sexyarchaeology.com, I thought maybe this would vibrate the handles for the *AHEM* ladies... |
|
| |
I was watching the Diry Jobs where Mike tried to get the dry cement out of a cement mixer. They had this same problem on Mythbusters, ultimately answered with the Alexandrian solution of exploding the entire cement mixer. |
|
| |
I wonder if vibrating the drum of the mixer would loosen the cement. One could put the vibrator on and leave it on, maybe for days. |
|
| |
usually you can use the natural hammering action of the hydraulics and the looseness in the joints to pound the bucket pretty hard. I've never seen a pro struggle to dislodge the dirt in the bucket. couple of good jabs on the bucket control and you're good to go. |
|
| |
and that's why a lot of companies prefer to have
women running the heavy equipment. Hammering is
hard on the running gear |
