[0004]

The above-mentioned conventional technology has the following problems. (A) Since the shape of the hole that fits into the low-speed rotation shaft of the anti-winding plate is a full-circle, when shredding the explanted culm that has been cut for a long time, dust or The mud gradually enters, and the dust and mud that have entered once accumulates without being discharged because the fitting holes are all around the circle, thereby increasing the resistance of the fitting part and smooth rotation. There is an inconvenience that it does not exist, leading to a breakage of the winding prevention plate and the like. (B) Since the fitting hole of the winding prevention plate is a full circle, when replacing the fitting part of the winding prevention plate is worn or damaged, remove the low-speed rotation shaft from the cutter case, and remove the blade. There are also troublesome drawbacks, such as the inability to replace without removing the partition pipe. (C) When the culm is cut, a phenomenon occurs in which the high-speed rotation shaft and the low-speed rotation shaft bend outwardly depending on the amount of the supplied culm. At that time, especially in the case of Japanese Patent Publication No. 6-20394,
If there is no play between the fixing hole supporting one end of the wrap prevention plate and the support rod, strong friction occurs between the fitting hole surface of the wrap prevention plate and the low-speed rotation shaft, and the members wear each other. There is a problem of hastening.

As shown in FIG. 2, reference numeral 11 denotes a swing metal whose lower end is pivotally supported outside the side plate of the cutter case 3. Both ends of the low-speed rotating shaft 4 are rotatable above the swing metal 11, respectively. Both ends of the low-speed rotary shaft 4 are slidably penetrated through arc-shaped guide slots (not shown) provided in the side plate of the cutter case 3. The pair of the feeder 6 and the feeder 7 swings a fixed length about the pivot point of the swing metal 11, and this action mechanism adjusts the length of the culm to a short or long length as described later. Used when

The high-speed rotating shaft 5 has a large-diameter rotary blade 12 for cutting the culm long and a small-diameter rotary blade 13 for cutting the culm short.
Are arranged at appropriate intervals. That is, the edge portions of the rotary blades 12 and 13 can be inserted into the gap 8 between the feed blade and the feed plate 7, respectively.
Is smaller than the number of small-diameter rotary blades 13, and when only the cutting edge of the large-diameter rotary blade 12 intervenes in the gap 8 by adjusting the rotation of the swing metal 11, the culm is cut into a long shape, When the small rotary blade 13, more specifically, both rotary blades 12 and 13 intervene in the gap 8, the culm is cut short. (See FIG. 5, FIG. 6, FIG. 7, FIG. 8, FIG. 8) In the figure, 14 is a partition member having a plurality of projecting plates 15 protruding radially, 3a is a switching used when cutting and collecting culms.

In the disk-type cutter 1 constructed as described above, the present invention is directed to improvement of a plate for preventing winding of a cut culm as described below.

Reference numeral 20 denotes the feed blade 6 and the feed plate 7
It is a winding prevention plate of a cutting culm which is interposed in a gap 8 formed therebetween in a rotationally immovable manner, and an inner portion of each of the winding prevention plates 20 is provided on an outer periphery of the cylindrical portion 9 of the feeding plate 7. On the other hand, there is provided a notched notch 21 which is detachable from the outside and which also exceeds the semicircle of the cylindrical portion 9, and is inclined downward from the lower inner end of the notch 21 to the outside. The discharge guide surface 22 of the cut excrement is formed. On the other hand, a guide slot 23 in a horizontal position is provided at the upper end of the outer end of each winding prevention plate 20, and a support rod 24 laid on the cutter case 3 is inserted through the guide slot 23, so that the bending of the low-speed rotating shaft 4 is prevented. Wrap prevention plate 20
Are configured to follow.

The notch recess 21 is formed in the cylindrical portion 9 of the feeding plate 7.
As shown in FIG. 4, when the anti-winding plate 20 is fitted from the outside of the cylindrical portion 9 via the gap 8, as shown in FIG. The upper and lower ends of the opening of the place 21 open to B, that is, the diameter of the cylindrical portion 9, and the upper and lower ends of the opening of the notch recess 21 shrink as shown at A during fitting. The part 9 is fitted so as not to be easily pulled out.

By inserting and supporting the guide slots 23 of the winding prevention plates 20 with the support rods 24, even if a large amount of culm is thrown in and a large cutting resistance is applied to the low-speed rotating shaft 4, bending occurs. This bending is absorbed by the sliding action of the guide elongated hole 23 and the support rod 24 of the winding prevention plate 20 that moves together with the low-speed rotation shaft 4, and the contact resistance between the notch recess 21 and the cylindrical portion 9 of the feeding plate 7. Has no change, the anti-winding plate 2

As shown in FIG. 6 and FIG.
May be inserted and arranged in a gap 8 of a pair consisting of a feeding blade 6 and a feeding plate 7 at a portion corresponding to about half of the entire length of the culm, more specifically, about half of the root side of the culm. The reason is,
This is because it contains a large amount of water or is wet, and the root of the thick stem, which is thicker than the tip of the spike, is more likely to be wound around the low-speed rotating shaft 4, specifically, the outer periphery of the cylindrical portion 9 in the gap 8. However, since the properties of the culm are various, it is a matter of course that the winding prevention plate 20 may be interposed in the gap 8 between the feed blade 6 and the feed plate 7 of all pairs.

Next, a practical embodiment of the anti-winding plate of the present invention will be described with reference to FIG. A circular stress dispersing hole 2 is formed at the deepest part in the approximate center of the notch recess 21 formed in the winding prevention plate 20.
5 is formed to form a slit 26 having a slit structure, thereby facilitating the opening property of the opening of the cutout recess 21 having a partially circular structure. With this configuration, the dimension A shown in FIG. 4 can be further reduced, that is, the degree of fitting of the notch recess 21 to the outer periphery of the cylindrical portion 9 of the feeding plate 7 can be increased.

A guide slot 23 having a notch structure with an outer end opened to the outside.
The support rod 24 can be freely inserted and removed from the opening of the guide slot 23a. By providing such an open guide slot 23a, it is possible to mount the winding prevention plate 20 at the time of assembling at least without disassembling the support rod 24 with respect to the cutter case 3.
Replacement work in case of breakage can be performed easily. The open structure of the guide slot 23a is not limited to the illustrated one.

[0023]

According to the configuration of the present invention as described above,
The following effects can be obtained. (A) When the culm is shredded by a disk-type cutter, the shredded culm intervenes in the gap between the feeding blade and the feeding plate and is wound around the low-speed rotating shaft, specifically the cylindrical portion, and cuts the culm. It goes without saying that the efficiency is not hindered, and in particular, in the present invention, the anti-winding plate can be fitted into and removed from the cylindrical portion of the feeding plate corresponding to the gap portion, and also exceeds the semicircle of the cylindrical portion. By providing a notch recess, and by forming a discharge guiding surface of the cutting culm that is inclined downward outward from the lower end of the notch recess, between the notch recess, the feeding blade, and the feeding plate Even if dust or mud attached to the culm adheres, it does not accumulate due to the continuous removal action by the opening of the notch recess. Further, since the anti-winding plate can be mounted without disassembling the low-speed rotating shaft, the assembling work and the replacing operation of the anti-winding plate can be easily performed. (B) Claim 2
In the above, the anti-winding plate is made of an elastic synthetic resin material, so that the opening of the opening of the notch recess can be easily expanded, and the assembling and replacing work of the anti-winding plate can be further simplified. I can do it. (C) In the third aspect, a long hole is formed in the anti-winding plate in a horizontal posture, and the long hole is inserted and supported by the support rod. Even if the shaft is flexed, the anti-winding plate moves together with the low-speed rotating shaft, so that the rotational resistance in the cylindrical portion and the notch recess is always unchanged and constant, preventing wear of both. Can be. (D) According to the fourth aspect, since the long hole for inserting and supporting the support rod has an open structure, the assembling work and the exchange work of the winding prevention plate can be easily performed without disassembling at least the support rod from the cutter case. And workability can be improved.
