【考案の詳細な説明】 本考案は、コンバイン等における殻稈掻込用掻込輪体構
造に関する。[Detailed Description of the Invention] The present invention relates to a raking wheel structure for raking culm in a combine harvester or the like.

コンバイン等における殻稈掻込部は、周囲に掻込歯体を
突設した掻込輪体を左右一対に並設して両輪体の掻込歯
体同志が噛み合いながら回転する部分で殻稈を掻き込む
ように構成するのが殻稈の掻込洩れや脱落を生じず有利
である、ところがこのようにすると、歯体同志が噛み合
いながら作動するので摩耗が早められ易く、殊に殻稈へ
の影響を考慮して掻込輪体を合成樹脂材等で形成する場
合には一層摩耗傾向が強まる。The culm raking part of a combine harvester, etc. is a part where a pair of raking wheels with raking teeth projecting around the periphery are arranged side by side on the left and right, and the culm raking parts of both wheels rotate while meshing with each other. It is advantageous to have a configuration that allows the culm to be scraped in without causing leakage or falling off of the culm.However, in this case, the teeth operate while meshing with each other, which tends to accelerate wear, and especially damage to the culm. If the scraping wheel is made of a synthetic resin material or the like in consideration of the influence, the tendency for wear will be even stronger.

そこで、輪体部分に対して歯体を着脱できるようにし摩
損したときには歯体を交換できるようにすることが考え
られるが、上記のような歯体噛合構造の場合には、歯体
を確実強固に定位置に保持されるようにして置かないと
噛み合いや掻込作動に不都合をきたすので、強固な取付
になすために取付構造が複雑となり着脱作業のほうは簡
単にならない不便が起る。Therefore, it is possible to make the tooth body removable from the ring part so that the tooth body can be replaced when it becomes worn out. However, in the case of the tooth body meshing structure as described above, it is necessary to ensure that the tooth body is firmly strengthened. If it is not held in a fixed position, it will cause inconvenience to the engagement and raking operation, so the mounting structure will be complicated in order to ensure strong mounting, and the installation and removal work will not be easy.

本考案は、掻込歯体の着脱操作は著しく簡単でありなが
ら、取付けの際は所定の位置に的確強固に取付けられる
掻込輪体構造の提供を目的として実施したものである。The purpose of the present invention is to provide a rake ring structure that allows the rake tooth body to be mounted and removed in a very simple manner, and yet to be firmly and accurately attached to a predetermined position.

以下図面に示す実施例について説明する。The embodiments shown in the drawings will be described below.

第１図はコンバインにおける前方刈取部の概略側面図を

示す。FIG. 1 shows a schematic side view of the front reaping section of a combine harvester, in which numeral 3 is a weeding body, 4 is a pulling device, 5 is a reaping frame, 6 is a cutting blade, 7 is a lower conveying chino, 8 is a transfer chino, 9
10 indicates the ear conveying tine, and 10 indicates the foot chain of the threshing device.

下部搬送チェノ７の前部上方とその側方にはそれぞれ円
状盤体Ａ、Ａを下方のギヤボックス１１から相互に逆転
駆動させるようにするが、該円状盤体Ａは合成樹脂製で
形成するとともに、外周から中心内方に向けて周囲方向

上下面に貫通する係止ピン１３挿込用の孔１４を形威し
、円状盤体Ａの中心寄り周囲には駆動側に取付けるボル
ト用の取付孔１５を形成する。At the upper front part of the lower conveyance cheno 7 and at the side thereof, circular disk bodies A, A are respectively driven in reverse from a lower gear box 11, and the circular disk bodies A are made of synthetic resin. At the same time, a plurality of insertion holes 1 are provided at regular intervals in the circumferential direction from the outer periphery toward the center inward, partitioned by partition plate portions 12, and the inner band of each insertion hole 1 is A hole 14 for inserting a locking pin 13 penetrating through the upper and lower surfaces of the circular disk body A is formed, and a mounting hole 15 for a bolt to be attached to the drive side is formed around the center of the circular disk body A. .

ａは合成樹脂製の掻込歯体で、その先端部１６を掻込部

在に嵌入できるよう形成し、その基部２における上下面
には係止ピン１３を挿入できる孔１７を貫通させて形成
するが、その孔１７から端部にかけて割溝１８を細く形
成する。Reference numeral a designates a scratching tooth body made of synthetic resin, whose tip 16 is formed as a scratching part, and whose base 2 is formed so that it can be removably inserted into the insertion hole 1, and the upper and lower surfaces of the base 2 are A hole 17 into which the locking pin 13 can be inserted is formed through the hole 17, and a groove 18 is formed thinly from the hole 17 to the end.

したがって、各歯体ａの基部２を挿込孔部１に挿入して
係止ピン１３を孔１４および１７に上方から挿入すると
、歯体ａは上下方向にも回転方向前後にも固定されて歯
体ａの先端部１６側が円状盤体Ａの外周方向に向は突出
し、従来のスターホイルと同様の掻込輪体に構成できる
。Therefore, when the base 2 of each tooth a is inserted into the insertion hole 1 and the locking pin 13 is inserted into the holes 14 and 17 from above, the tooth a is fixed both in the vertical direction and in the rotational direction. The tip 16 side of the tooth body a protrudes toward the outer circumferential direction of the circular disc body A, and can be constructed as a scraping wheel similar to a conventional star wheel.

しかして第２図に示すように、両掻込輪体が相互に逆転
し両方の歯体ａ、ａが噛合いなから殻稈をその間に掻込
んで掻込作業を行なう。As shown in FIG. 2, the two scraping wheels are reversed and the teeth a, a are in mesh with each other, so that the culm is scraped between them to perform the scraping operation.

この種の掻込輪体は殻稈を掻込むとともに相互の噛合に
より摩耗が激しいが、摩耗した場合には、その歯体ａを
係止ピン１３を抜いて挿込孔部１から外し、新しい歯体
ａと取換えることができる。This type of raking wheel scrapes the culm and is subject to severe wear due to mutual meshing, but when it wears out, remove the locking pin 13 and remove the tooth a from the insertion hole 1, and replace it with a new one. It can be replaced with tooth body a.

操作は著しく容易となる。In this way, the present invention arranges a pair of raking wheels, each consisting of a circular disc body A and a raking tooth body a that is detachably attached thereto, in a pair on the left and right in a reaping section, etc., so that each raking wheel In the shell culm scraping structure in which the teeth engage with each other and are rotated, the circular discs A, A each have an insertion hole 1 into which the base 2 of each scraping tooth is fitted. . . . are arranged at regular intervals around the outer circumference, and when installed, the scratching tooth body is prevented from moving forward and backward in the rotational direction and in the vertical direction by fitting between the base 2 and the insertion hole 1. Because it is fixed, even if each tooth body is removable in a scraping wheel configured to engage and rotate the scraping tooth bodies, each tooth body can be sheath-fitted. Since it can be firmly and securely fixed in a predetermined position, there will be no inconvenience in the meshing operation, and since the fixed position is fixed in the above-mentioned sheath fitting structure, the gap between the circular disk body and the base of the tooth body is fixed. Since removal requires only a simple lock, the operation of attaching and detaching the tooth body becomes extremely easy.

なお、歯体の取付けは上記のごとく簡単に行えるので、
挿込孔部に対する歯体の取付数変更や形状の異なる歯体
の付換なともごく簡単に実施できることとなって便利に
用いることができるのである。In addition, since the tooth body can be installed easily as described above,
It is very easy to change the number of teeth attached to the insertion hole and to replace teeth with different shapes, making it convenient to use.
