Abstract

A method of collection of sphagnum moss comprising a motorized cutting and collection of at least a portion of the sphagnum moss. The cutting is performed in a direction substantially parallel to the ground and in a direction substantially vertical to the ground, while leaving the sphagnum moss anchored to the ground.

Claims (23)

1 . Cutting unit for cutting sphagnum moss, said unit comprising a first pair of horizontal powered parallel blades spaced apart from about 2 cm to about 30 cm and a second pair of vertical powered parallel blades spaced apart from about 40 cm to about 400 cm, said blades of said first pair and second pair being positioned and configured to cut said sphagnum moss in an intermediate portion while leaving the sphagnum moss anchored to the ground.

2 . Cutting unit according to claim 1 , wherein the first pair of horizontal powered parallel blades is a pair of chainsaws.

3 . Cutting unit according to claim 2 , wherein the chainsaws are configured such that the first pair of horizontal powered parallel blades comprises a first chainsaw disposed above a second chainsaw, the first saw has chain being disposed horizontally and being advanced with respect to the second chainsaw so that when the cutting unit contacts an element to be cut, said element first contacts the first chainsaw and said element then contacts the second chainsaw.

4 . Cutting unit according to claim 2 , wherein the second pair of vertical powered parallel blades is a pair of chainsaws.

5 . Cutting unit according to claim 2 , wherein the second pair of vertical powered parallel blades is a pair of shear blades.

6 . Sphagnum moss harvesting system comprising a cutting unit according to claim 1 , and a motor for moving said cutting unit.

7 . System according to claim 6 , further comprising a rail system for supporting said cutting unit.

8 . System according to claim 6 , further comprising at least one roller for dewatering.

9 . System according to claim 6 , further comprising rollers for dewatering.

10 . System according to claim 6 , further comprising cylinders for pre-dewatering.

11 . Cutting unit for cutting sphagnum moss, said unit comprising a first pair of substantially parallel blades, laid out substantially according to a first orientation, and spaced apart from about 2 cm to about 30 cm and a second pair of blades, substantially parallel, laid out substantially in a second orientation, and spaced apart from about 40 cm to about 400 cm, said blades of said first pair and second pair being positioned and configured to cut said sphagnum moss,

wherein the first pair of blades is a pair of chainsaws,

and wherein the chainsaws are configured such that the first pair of blades comprises a first chainsaw disposed above a second chainsaw, the first saw has chain being disposed horizontally and being advanced with respect to the second chainsaw so that when the cutting unit contacts an element to be cut, said element first contacts the first chainsaw and said element then contacts the second chainsaw.

12 . Cutting unit according to claim 11 , wherein the first orientation is horizontal.

13 . Cutting unit according to claim 11 , wherein the second orientation is vertical.

14 . Cutting unit according to claim 11 , wherein the second pair of blades is a pair of chainsaws.

15 . Cutting unit according to claim 11 , wherein the second pair of blades is a pair of circular blades.

16 . Cutting unit according to claim 11 , wherein the second pair of blades is a pair of shear blades.

17 . Sphagnum moss harvesting system comprising a cutting unit according to claim 11 , and a motor for moving said cutting unit.

18 . System according to claim 17 , further comprising a rail system for supporting said cutting unit.

19 . System according to claim 17 , further comprising at least one roller for dewatering.

20 . System according to claim 17 , further comprising rollers for dewatering.

21 . System according to claim 17 , further comprising cylinders for pre-dewatering.
