Automatic feeder

There are many types of automatic feeders. The one i like is so called screw feeder. The ideea is explained bellow in the picture :


So we need a screw. It's complicated to make one home, without special tools. After a few days of thinking i came up with this:


This is so called meat grinder, that has screw we need. I will try using the whole meat grinder, without some parts. Let's disassemble our meat grinder.


I will use only parts 3, 4, 6 and 7. I will use plate (number 6) with big halls, and not the one in the above picture. I found this one:


It has big halls, so the food can come out easily. It is not enough to use simple motor, because it has to much rpm's. We need a motor with some gears, so called gear motor. We can use something like this:
This gear motor has around 120-180 rpm's.

  2. In theory this should work. BUT... it the food is for large animals, I'm afraid that the food will clog before going into the meat grinder. A solution for this is to have part 4 inserted into the food recipient and use it to push it outside the recipient...
    p.s. asta ca sa fie in engleza discutia :p

    1. In case first variant will crash, your idea will be v.2.
