Description

[Detailed description of the invention] Generally, in sugar cane fields, etc., leaf sheaths such as sugar cane are left unattended in the field, and if this continues, the tilling work by the tilling claws of the tilling machine will be hindered by the leaf sheaths, making it difficult to cultivate. This was because it could not have been carried out.

Therefore, conventionally, prior to tillage work, leaf sheaths in fields are shredded using a tillage machine equipped with a leaf sheath shredding device.

The present invention relates to a shredding device for shredding leaf sheaths of sugar cane, etc., which is installed on such a tiller, and is particularly aimed at achieving good shredding action.

The leaf sheath shredding device of the present invention that solves this problem has a cutting blade 15 detachably attached to the tilling claw shaft 9, and a mounting plate 16 attached to the circumferential surface of the cutting blade 15 in the axial direction of the tilling claw shaft 9. A plurality of cutting blades 17 are fixed to the mounting plate 16 in a direction perpendicular to the tilling claw shaft 9 in parallel at regular intervals. A winding prevention blade 18 is provided near the peripheral surface, and
A predetermined number of fixed blades 20 are arranged slightly in front of the anti-wrapping blade 18 and lateral to the tilling case 8 and closely follow the rotation locus of the cutting blade 17, with the tips of the fixed blades 20 aligned with the cutting blade. It is characterized in that it is arranged so as to protrude close to the peripheral surface of the body 15, and that a notch 16a is provided in a part of the mounting plate 16, which is deeper than the tip position of the fixed blade 20.

Next, one embodiment of the present invention will be explained with reference to the drawings.
This is a usual tilling machine in which a series of tilling parts 4, 4 are connected in parallel, and in this tilling machine 1, each tilling part 4 is connected in parallel.
However, a transmission cylinder 7 that can be expanded and contracted laterally is provided protruding from a gear box 6 that receives input from the input shaft 5 of the tractor 20, and a tilling case 8 is fixed to the transmission cylinder 7. A tilling claw shaft 9 driven by an input shaft 5 via a box 6 transmission cylinder 1 and a tilling case 8 is supported in a protruding manner on both sides of the tilling case 8.

In addition, 10 is a tilling cover supported by each tilling case 8.

In this embodiment, one of the tilling sections 4 is equipped with the shredding device 11 according to the present invention, and the other end portions of the tilling claw shaft 9 of the other tilling section 4 are equipped with conventional ones. Similarly, a support tube 13 in which an appropriate number of tilling claws 12, 12, etc. are installed is attached with bolts 14 so that they cannot rotate relative to each other, and the shredding work of leaf sheaths and the tilling work are carried out simultaneously. The structure of the shredding device 11 in this embodiment will be explained below, although this is a contrivance to make the cutting process easier.

That is, a drum-shaped cutting blade 15 of an appropriate diameter is attached to the supporting tube 1 at both ends of the one tilling claw shaft 9.
3, it is attached with a bolt 14 so as to be relatively non-rotatable, and four annular mounting plates 16, 16° 16.16 are mounted on the circumferential surface of each cutting blade 15 at regular intervals in the axial direction. The mounting plates 16 are fixed to each other in a parallel manner, and double-edged triangular cutting blades 17 are detachably fixed to three equally spaced locations on each mounting plate 16.

The mounting position of each cutting blade 17 on each mounting plate 16 is as follows for each cutting blade group 1.
γ, 17, 17, 17 are set to be parallel to each other in the axial direction of the cutting blade 15, and the attachment position of each cutting blade 15 to the tilling claw shaft 9 is determined by the axis of one of the cutting blades 15. Each cutting blade group 17, 17, 17.17 parallel to the direction is parallel to the axial direction of the other cutting blade body 15 - cutting blade group 17,
17, 17, 17 and other adjacent cutting edge groups 17, 17
, 17, 17 so that they can attack each other.

The tilling cover 10 has an anti-wrapping blade 18 which is located immediately behind the tilling case 8 and extends to the vicinity of the circumferential surface of the cutting blade 15 when viewed from the direction along the axial direction of the tilling claw shaft 9. are removably fixed 19 and are located slightly in front of the anti-wrapping blade 18 and on both sides of the tilling case 80, so as to be close to the rotation locus of each cutting blade 170 of each cutting blade body 15. A predetermined number of fixed blades aligned along the axis of each cutting blade body 15, that is, eight fixed blades 20, 20, whose tips are positioned directly adjacent to each mounting plate 16, are aligned along the axis of each cutting blade body 15. Fixed in parallel in the direction and removably fixed 2L21...
・Shidaru.

The winding prevention blade 18 and each of the fixed blades 20 have their rear end surfaces acid-shaped, and each mounting plate 16 of each cutting blade 15 is provided with a tilling claw shaft 9 for each cutting blade 15. The notch 16aL-shaped housing allows the tips of the fixed blades 20 to pass through each other so that each mounting plate 16 does not interfere with the tips of the fixed blades 20 when attached to the blade.

Next, to explain the operation of the above embodiment, when the tiller 1 is run in a field such as a sugar cane field where leaf sheaths such as sugar cane are left, the leaf sheaths left in the field will be removed by the shredding device. 11 In other words, as each cutting blade body 15 rotates, each cutting blade 17 passes through the farmland and shreds finely.

At this time, each cutting blade 1T that rises after the cutting action is finished lifts up the leaf sheath above the field, and the lifted leaf sheath moves into the gap 22. between each cutting blade 15 and the tilling case 8.
However, in the shredding device 11 according to the present invention, the leaf sheath lifted as described above may wrap around the gap portions 22, 22. It is blocked by the anti-stick blade 18, cut by the anti-stick blade 18, and further shredded by the latter fixed blade 20.

Therefore, when a leaf sheath is left in a field, it is
Even after being subjected to the cutting action by the anti-wrapping blade 18 and the fixed blades 20, the cutting action is extremely well achieved. There is no risk of it wrapping around the gap portions 22, 22.

Furthermore, in the above embodiment (), since each cutting edge 1γ is fixed to the annular mounting plate 16, the leaf sheath is attached to each mounting plate 16.
The cutting action of each cutting blade 17 is applied while the leaf sheath is pressed down with its zero circumferential surface, so that the leaf sheath can be shredded more effectively.

In the field where the leaf sheaths have been shredded as described above, the tilling work with the tiller claws 12 can be carried out smoothly without being hindered by the leaf sheaths. A cutting device 11 is installed, and the other tilling section 4 has conventional tilling claws 12, 12...
is installed, so it is possible to simultaneously perform shredding work on leaf sheaths and tilling the field where the leaf sheaths have already been shredded.
This is extremely convenient when performing so-called inter-tillage work.

Note that the configuration of the cutting device 11 is of course not limited to the above embodiment, and includes a cutting blade 17, a winding prevention blade 18, a fixed blade 20,
The shape, number, etc. of these are set as appropriate.

As is clear from the above explanation, the device for shredding leaf sheaths, such as sugar cane, of the present invention shreds leaf sheaths left in the field with each cutting blade of the cutting blade, and then The structure is such that the leaf sheath lifted by the cutting blade is continuously cut by the anti-wrapping blade and the fixed blade. It does not wrap around and rolls very well.

Therefore, in a sugar cane field or the like where the leaf sheaths have been shredded by the shredding device of the present invention, the tillage work can be carried out satisfactorily without being hindered by the leaf sheaths.

In addition, the cutting blade is installed on the periphery of the cutting blade via the mounting plate, and a notch deeper than the tip of the fixed blade is provided in a part of the mounting plate, so that the above-mentioned effect can be achieved. The fixed blade is visible near the circumferential surface of the cutting blade, but when attaching and removing the cutting blade to the tiller shaft, the tip of the fixed blade can pass through the mounting plate in the axial direction of the tiller shaft. Since the tip of the fixed blade and the mounting plate are located on the interference side, the cutting blade body can be attached and detached without the need to remove the fixed blade or the attachment plate, making the attachment and detachment work easier.
