Description

[Detailed Description of the Invention] [Purpose of the Invention] (Industrial Application Field) The present invention relates to a foliage cutting device, for example, a device for cutting foliage such as sugar cane foliage and tree heads.

(Prior Art) Conventionally, when harvesting sugar cane, the stems, leaves and upper tree heads are generally cut off and left in the field.

When the stems, leaves and tree tops rot and are returned to the field, they are effective as highly organic matter, so in order to rot them as quickly as possible, they are mixed with soil and piled up between furrows.

(Problems that the Committee is trying to solve) As mentioned above, if the leaves remain long during furrow work, the problem is that they may wrap around the rotor shaft used for the work, making it impossible to work. There is a point.

For this reason, the cutting of the stems and leaves is carried out as a preliminary work to the ridge-filling work, but with the existing equipment used for this cutting process, not only is it still not possible to prevent the stems and leaves from becoming entangled, but it also requires a large amount of horsepower. There's a problem.

Therefore, the present invention was devised in view of the above points, and aims to prevent the stems and leaves from wrapping around each other, and to easily and reliably cut the stems and leaves into predetermined short lengths and easily return them to the field. The object of the present invention is to provide a foliage processing device that can perform the following.

[Structure of the idea]

(Means for Solving the Problems) The foliage cutting device of the present invention has a rotary shaft rotatably horizontally mounted on the machine frame, and a plurality of cutting coulters arranged at predetermined intervals in the axial direction of the rotary shaft. are arranged and fixed in parallel, and a plurality of rotating collars are rotated, each having a pressing part that presses down the foliage from above and a plurality of blade pieces that send out the cut foliage backwards on the rotating shaft between each cutting coulter. The proximal ends of a plurality of guides, which are freely mounted on shafts and whose tips protrude from below the rear to below the front of each cutting coulter to guide the stems and leaves to the respective cutting coulter, are fixed to the machine frame.

(Function) According to the foliage processing device of the present invention, when the machine frame is towed in the field and the rotating shaft is rotated, each cutting coulter fixed to the rotating shaft is moved as shown in FIGS. 1 and 2, for example. At the same time, as each cutting coulter rotates and the machine advances, long stalks and leaves such as sugar cane scattered in the field are successively picked up by the tip of each derivative. As the cut-up foliage progresses, it is guided from the tip toward each of its adjacent cutting coulter, and the foliage on each guide is drawn in by the rotation of each cutting coulter and is also pushed by the rotating collar. While being pressed down from above by a section, each guide member is used as a receiving blade to rotate each cutting coulter to a predetermined length, that is, the length between each cutting coulter. Short stems and leaves are sent rearward by the rotation of each blade of each rotating collar.
