本発明はゴム弾性履帯（以下ゴムクローラという）の構
造に関し、特に作業時における株抜き防止、ワラ詰まり
防止を目的としたゴムクローラを提供することにある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a rubber elastic crawler track (hereinafter referred to as a rubber crawler), and an object of the present invention is to provide a rubber crawler specifically designed to prevent stock removal and straw clogging during work.

。Conventionally used rubber crawlers are endless bands made entirely of rubber, with horizontal reinforcing core materials extending in the width direction of the band embedded at predetermined intervals in the longitudinal direction of the band, and A tensile reinforcing core material is wrapped around the outer periphery of the reinforcing core material and buried along the longitudinal direction of the strip, and a grounding lug is formed on the outer peripheral surface of the strip, and a grounding lug is formed between each horizontal reinforcing core material. It has a structure in which sprocket engagement holes are arranged in a row in the longitudinal direction.
しかるに走行時には稲の切株の先端がスプロケット係合
孔内に侵入することとなり、この状態で転輪、誘導輪と
横補強芯材間にはさまれるなどにより株が引き抜かれて
しまいこの株が未刈取揺上や刈刃上に落ちる為種々トラ
ブルの原因となっている。However, when running, the tip of the rice stump will enter the sprocket engagement hole, and in this state, the stump will be pulled out due to being caught between the rolling wheels, guide wheels, and horizontal reinforcing core material, and the stump will remain unused. It causes various troubles because it falls on the mowing machine or onto the cutting blade.

力の伝達が充分でなくなるばかりか、脱輪現象の発生も
しばしばである。Furthermore, as this phenomenon continues during driving, the sprocket engagement hole becomes clogged with stumps and straw, and a large amount of mud adheres to the sprocket engagement hole, resulting in insufficient transmission of traction and driving force. , derailment often occurs.
かかる欠点を排除するために、従来、実開昭４９−６１
２３４号に示すように、スプロケット係合孔の外周側を

トとの正常な係合が損なわれるという問題がある。In order to eliminate such drawbacks, conventionally,
As shown in No. 234, a structure was proposed in which the outer circumferential side of the sprocket engagement hole is closed to prevent rice stumps, straw waste, etc. from entering the retaining hole from the outer circumferential side and blocking it. However, on the other hand, if soil or the like enters the engagement hole whose outer circumferential side is closed from the inner circumferential side and becomes clogged, it is difficult to remove it, and there is a problem that normal engagement with the sprocket is impaired.

はスリットが設けであることにある。The present invention is an attempt to improve these drawbacks, and is characterized by an endless band made entirely of rubber. A horizontal reinforcing core material that extends is buried, and a tensile reinforcing core material is wrapped around the outer periphery of the horizontal reinforcing core material along the longitudinal direction of the strip. In a rubber crawler in which sprocket engaging recesses are arranged in a longitudinal direction between each horizontal reinforcing core material, the horizontal reinforcing core material is substantially embedded in the rubber in the sprocket engaging recesses, and the sprocket A rubber thin layer is formed on the outer circumferential side of the retaining portion, and this thin rubber layer is provided with small holes or slits for discharging water and mud.
以下図面について詳述する。The drawings will be explained in detail below.
第１図は従来のクローラにおける走行後の接地表面の写
真であって、スプロケット保合孔はゴムクローラ１の中

がびっしり詰まってしまうものである。Figure 1 is a photograph of the ground contact surface of a conventional crawler after running, and the sprocket retaining holes are opened in a row in the center of the rubber crawler 1, but these holes are packed with stumps, straw waste, etc. It's something to put away.
図中、３は接地ラグを示す。第２図は本発明を適用した
ゴムクローラの外周表面を示すものであり、第３図は第
２図中の■−■線に沿う断面図、第４図は第２図中のＩ
Ｖ−ＩＶ線の断面図である。In the figure, 3 indicates the ground lug. FIG. 2 shows the outer peripheral surface of a rubber crawler to which the present invention is applied, FIG. 3 is a sectional view taken along the line ■-■ in FIG. 2, and FIG. 4 is a cross-sectional view taken along the line I in FIG.
It is a sectional view taken along the line V-IV.
図中１０はゴムクローラ、１１は接地ラグ、１２は横補
強芯材、１３はゴム薄肉層を示す。In the figure, 10 is a rubber crawler, 11 is a grounding lug, 12 is a horizontal reinforcing core material, and 13 is a thin rubber layer.

スプロケット（図示せず）が係合した際にこのスプロケ
ットの歯先に接触しない位置をもってゴムクローラ１０
と一体に形成されるものである。As is clear from these figures, the thin rubber layer 13 covers the sprocket engaging recess 14 (not shown in FIG. 2) from the outer circumferential side of the core material 12; When the rubber crawler 10
It is formed integrally with the
従って、場合によっては図示はしないが平板状のゴム薄
肉層１３であってもよいが、一般には図示するように外
周表面側に凸形となす断面時用状のゴム薄肉層１３であ
るのが好ましい。Therefore, in some cases, although not shown, the thin rubber layer 13 may be in the form of a flat plate, but in general, the thin rubber layer 13 used in the cross section is convex on the outer peripheral surface as shown in the figure. preferable.
尚てのゴム薄肉層１３はスプロケットの歯先に接触せず
にスプロケット係合凹部１４を被蓋すればよいから、第
５図に示すようなスプロケット係合凹部１４を形成する
ゴムを前後左右からせり出してゴム薄肉層１３としても
良いことは勿論である。Since the thin rubber layer 13 only needs to cover the sprocket engaging recess 14 without contacting the tips of the sprocket teeth, the rubber forming the sprocket engaging recess 14 as shown in FIG. Of course, the thin rubber layer 13 may be formed by protruding.
このゴム薄肉層１３は、ゴム中に埋設されている引張補
強芯材１２の埋設されている位置と水平位置が等しいか
又はこれよりも外周側に履帯との接触固定部即ち膨山部
が存在するのが好ましく、更にはスプロケット係合凹部
の最狭部よりも外側よりこれが膨出しているのがよい。This thin rubber layer 13 has a contact fixed part with the crawler track, that is, a bulge part, which is at the same horizontal position as the buried position of the tensile reinforcing core material 12 buried in the rubber, or on the outer peripheral side thereof. It is preferable that the sprocket engaging recess be bulged from the outside of the narrowest part of the sprocket engaging recess.
これは走行時には引張補強芯材１２が主なる中心位置と

圧縮とに大別されるが、その一方何に位置することが耐
久性によく、かつスプロケットが係合して駆動した際に
スプロケット歯とこのゴム薄肉層１３と接触することが
ないようにするためである。This is because when running, the tensile reinforcing core material 12 is the main central position when running, so the outer circumferential side and inner circumferential side are roughly divided into tension and compression. This is to ensure that the sprocket teeth are not in contact with the thin rubber layer 13 when the sprocket is engaged and driven.
かＸるゴム薄肉層１３は作業中において破れたり、摩耗
したりしてはならず、したがってその厚さは２〜１０ｍ
ｍ程度のものが要求される。The thin rubber layer 13 must not be torn or worn out during operation, so its thickness should be between 2 and 10 m.
About m is required.
更に同様の目的のためにゴムクローラ１０の外周表面に
設けられる接地ラグ１１よりも外側にはみ出してはなら
ない制約がある。Further, for the same purpose, there is a restriction that the rubber crawler 10 must not protrude beyond the grounding lug 11 provided on the outer circumferential surface of the rubber crawler 10.
また泥土や木の排出用としてゴム薄肉層１３には第６図
ａ−６に示すが如き小孔１５やスリット１６又はこれら
の適当な組合せによる泥土排出機能をもたせである。Further, the thin rubber layer 13 is provided with a function of discharging mud and wood by means of small holes 15 and slits 16, as shown in FIG. 6a-6, or a suitable combination thereof.
このような小孔１５やスリット１６は、ゴム範肉層１３

ト１６となすこともできる。Such small holes 15 and slits 16 are formed in the rubber layer 13.
It is also possible to form the holes or slits in advance by making cuts or the like, but by forming the thin rubber layer 13 at the positions where the small holes or slits are to be formed, the rubber thickness is reduced to about 1 inch or less.
It is also possible to make small holes 15 and slits 16 by naturally abrading and breaking these during work.

■−■線に沿う断面図である。FIG. 7 is a perspective view of the outer circumferential surface of the rubber crawler 10 showing application of the present invention to a rubber crawler 10 using a so-called U-type lateral reinforcing core material 12, and FIG. It is a sectional view along a line.
この場合、ゴム範肉層１３は芯材１２の中央底部１２′
よりも外周側に断面−形状に形成されるのである。In this case, the rubber thickness layer 13 is located at the center bottom 12' of the core material 12.
It is formed in a cross-sectional shape on the outer peripheral side.

本発明のゴムクローラは以上のような構造を有するので
、切株の先端部がスプロケット係合孔に侵入することが
なくなり、したがって株ぬけやワラ詰まりが起こらず、
第１図に示すような状態が発生することは全くなくなる
。Since the rubber crawler of the present invention has the above-described structure, the tip of the stump does not enter the sprocket engagement hole, and therefore, the stump does not fall through or become clogged with straw.
The situation shown in FIG. 1 will never occur.

好な運転状態が維持される。Therefore, the transmission of traction force and driving force is sufficient, and there is no possibility of wheels coming off due to this. Also, by providing small holes or slits in the inner layer for discharging water and mud, soil, etc. does not get into the sprocket engagement recess. There is no accumulation and clogging, the engagement with the sprocket is always smooth and sufficient, and good operating conditions are maintained.
