Default Linear actuator help

I want to connect a linear actuator to a deer feeder timer so that it will open, stay open for the set amount of time, and then close automatically.

How do I do this?

I have a Chicken Butler set-up to open/close the door on my chicken coop and the operation is exactly what you are asking about.
The CB kit has a linear actuator (ball screw drive) and timer.

Not sure if a regular feeder timer would work? Your probably gonna need some kind of programmable controller. A actuator that’s rated for enough push and pull force for a feeder travels very slow. Might want to run it through a DPDT relay that’s rated for the actuator motor amperage.

You're going to need a spring return actuator if you want to do it that way. There are some variables to consider:
Only issue with a spring return type, is that you will need to provide power to it the entire time it needs to stay open.
Alternatively, you could do it with a reversing one that will likely save you a bit of battery, but you won't be able to pull it off with a feeder timer. There are options that would allow you to do it, but they will likely be more expensive than doing it with a feeder times.
Need to consider how long the stroke will be as well. What size is the hole you want to do this for, and what shape is it?

Have you seen this one?

Someone posted pictures of ice workings on this site before

Yes, just too much coin for only a mechanism

Here is a link to the working parts of the quiet feeder. This should point you in the right direction.

You need the same timer that is used in the HAMMER FEEDER.

Canny, are you wanting to try to make something like the "Eliminator Spinner Plate"?

No, I’m wanting to make something similar to the Ghost feeder shown in an earlier post

OK. I just found this. This feller used an actuator from an auto electric door lock to make his run on a 12v battery. He mentions it at about 1:42. And what else he used to build it.

Yeah, I’ve started looking into the door lock actuator idea. Problem is it’s a short throw, but I’m working through some ideas on how to increase that.

MAybe something like this:
https://www.amazon.com/POWERTEC-7013...54709296&psc=1
Along with a linear actuator. I would think you could easily make a spring return for it, and just use a door popper, although I haven't seen a door popper with a 4" range of motion, I am certain there are ways to make it happen.
With a spring return on the slider there, you should be able to use any timer out there, as long as your actuator matches your voltage requirements.

The reverse polarity to close is the tricky part. Good luck.

After rethinking this I think a regular timer would work. Find the actuator you want to use ( force and stroke) and time how long it takes to limit out. Set the feeder timer for that amount of seconds to open and close the actuator. You will still need a DPDT relay because the actuator has to be powdered to open then reversed to power close.

The Hammer Feeder Timer will fix that issue.

Yeah, the only way I could figure that one is to use limit switches for each end along with a relay to reverse teh polarity, but it starts getting a little too clumsy for use out there at that point in my opinion.
That's why I was thinking spring retract would be the simplest way to pull it off. Would even be easier with a damper actuator since it's all self contained, but then you have to be able to find one cheap.

Could you just not spring load the door plate so it slides back in place?

Something like this should work. Used this on a chicken coop. If you're close enough to wifi, they make one thats controlled by the app.

This. One timer controls a +12V relay. The other controls -12V.

Would a simple auto door lock actuator work for the mechanism?

I looked into all of this years ago. Bought components, spent too much time and money messing with it. Cheaper in the long run to simply buy a Hammer Feeder Mechanism.

Don't re-invent the wheel. This does exactly what you are wanting it to do.

THis has a linear actuator in it that can open or close whenever you want it to open or close. Did I miss read what you are looking for, if so then my bad.

It does, yes. I’m not wanting to regulate protein feed. Your appears to be a welded unit (at least from what I could see). I’m wanting to build my own “quiet” deer feeder that I can winch up into a tree to simulate “hand” corning.

I bought some dump feeders a number of years ago. They had a container that filled with corn and dumped from a timer. They dump maybe two cups of corn at each dump. If you want to feed more you could set up for multiple dumps around the same time. I always wanted to set one up over a hog trap to get hogs attracted then arm the trap. This might meet your needs.

Protein/corn same thing, you can open it to let it pour corn out as long as you want to get the amount of corn you want and it will close with really no noise involved

This looks like it would do exactly what you’re after. Just set it in the bottom of the barrel and hook to a timer with no spinner motor, just open hole. Will dump out corn for as long as you want it to.

$80 is pretty cheap too. Will still need a battery and timer, but you would need that anyway with what you’re trying to design.

You can waste a lot of time, energy, and corn, trying to figure out how to do what the ghost feeder already does.

I would think the old school dump feeder is gonna be your best bet. They are quiet and easy to regulate the amount of corn you want to put out. ** Only problem is finding dump feeders, I just spent about 20 minutes online trying to find one, but I dont guess anyone makes them anymore **
