The red bucket is the one you use to catch apples. It doesn't have Physics behavior.
The green "clone" bucket is stationary, it can be invisible or off-screen. This bucket and apples in it have Physics enabled. The green bucket is used to simulate natural physics movement of apples falling into the bucket. Positions and angles of these apples in the green bucket are then replicated for apples in the red bucket.
My example doesn't allow apples that are already inside the bucket to fall through the walls when you are moving it too fast. It still needs tweaking of course, for example when an apple is hit by the outside wall of the bucket, it should bounce off (currently it may get inside the bucket). You may also want to limit the maximum bucket speed etc.
I made some changes to the file, please re-download it:
You can try a completely different approach. In your original file, instead of using Drag&Drop, move the bucket with Physics actions - Set Force, Set Impulse, Set velocity. It will probably be less responsive, but collisions with apples should work much better.
