Abstract
The invention relates to a device for crumbling root crops into substantially equal sized pieces, comprising: a main frame having an inlet side and an outlet side; a root crop supply at the inlet side; at least one crumbling shaft rotatable supported in the main frame, the crumbling shaft being provided with a plurality of curved hooks, which are curved into a direction of rotation of the crumbling shaft; and a non-rotating cutting rake having a plurality of protrusions and recesses and forming a counter blade for the hooks, wherein the hooks are arranged for interlaced movement with said recesses of the non-rotating rake. The invention moreover concerns a system and a corresponding method.
Claims30
A device for crumbling root crops, preferably into substantially equal sized pieces, comprising:
- a main frame having an inlet side and an outlet side;
- a root crop supply at the inlet side;
- at least one crumbling shaft rotatable supported in the main frame, the crumbling shaft being provided with a plurality of curved hooks, preferably curved into a direction of rotation of the crumbling shaft;
- and
- a non-rotating cutting rake having a plurality of recesses and forming a counter blade for the hooks,
- wherein the hooks are arranged for interlaced movement with said recesses of the non-rotating rake.
The device of any of the preceding claims, wherein the curved hooks are curved about an angle of 30° to 90°.
The device of any of the preceding claims, wherein the curved hooks are displaced to each other provided about the circumference of the crumbling shaft.
The device of any of the preceding claims, wherein the curved hooks taper towards the tip.
The device of any of the preceding claims, wherein the curved hooks have a length in a range of 20 mm to 80 mm, measured along a center line of the hooks.
The device of any of the preceding claims, wherein the curved hooks have a cross section in a range of 100 mm2, measured at a foot portion and/or in a middle portion of the hooks.
The device of any of the preceding claims, wherein the curved hooks are axially offset to each other by a value in the range of 10 mm to 100 mm.
The device of any of the preceding claims, wherein the curved hooks are removably fixed to the crumbling shaft.
The device of any of the preceding claims, wherein the cutting rake is adjustable in height for adjusting a vertical distance to said crumbling shaft.
The device of any of the preceding claims, wherein the crumbling shaft is connected to a drive for driving the crumbling shaft.
The device of any of the preceding claims, comprising a cleaning rake adjacent to or opposite the cutting rake for stripping off root crop pieces from the hooks.
The device of any of the preceding claims, comprising a de-clogging device for de-clogging clogged root crops from the rake.
The device of any of the preceding claims, comprising a hopper at the inlet side of the frame.
The device of any of the preceding claims, comprising a set of first and second crumbling shafts supported in said frame, which are arranged for counter-rotating, wherein one rake is provided between the shafts having opposingly arranged protrusions and recesses.
