図４および図５に示すように、従来の切削ドラムＡ′は回転ドラム１の外周部 に、路面Ｂを切削するための複数のビット２を設けてある。このビット２は回転 ドラム１に溶接されたベース３上のホルダ４を介して着脱自在に取り付けられて いる。 As shown in FIGS. 4 and 5, the conventional cutting drum A' is A plurality of bits 2 for cutting the road surface B are provided. This bit 2 rotates It is detachably attached via a holder 4 on a base 3 welded to the drum 1. There is.
【０００３】 ビット２は回転ドラム１に整列状に取り付けられるために、図５に示すように 回転ドラム１の中心部から両側端にわたり、たとえば約９０°の角度に拡散する Ｖ字形に複数配列されている。各ビット２のベース３は隣接するベース３同士の 間隔が開いた状態に配列されている。さらに、ビット２の各列間には切削された 廃材を回転ドラム１の中心へ向けて効率よく送るために、ガイド板５をスクリュ ー状に突設してある。また、ビット２の各列間の回転ドラム１中心部には、回転 ドラム１の軸線方向にわたり、ガイド板５によって案内された廃材を掻き上げて 、図示しないベルトコンベアへ排出するためのブレード６を設けてある。0003 Since the bits 2 are attached to the rotating drum 1 in an aligned manner, as shown in FIG. Spread from the center of the rotating drum 1 to both ends, for example, at an angle of approximately 90°. A plurality of them are arranged in a V-shape. Base 3 of each bit 2 is between adjacent base 3s. Arranged with space between them. Furthermore, between each row of bit 2, there is a cut In order to efficiently feed the waste toward the center of the rotating drum 1, the guide plate 5 is screwed in place. It has a protruding shape. In addition, in the center of the rotating drum 1 between each row of bits 2, there is a rotating The waste material guided by the guide plate 5 is scraped up along the axial direction of the drum 1. , a blade 6 is provided for discharging to a belt conveyor (not shown).

従来の切削ドラムＡ′は切削深さを増大するとなると、ベース３の高さを高く し、これに伴いガイド板５の突出長さも長くして、廃材の通路となるいわゆるフ トコロを大きく確保する必要があった。ところが、ベース３を高くすると破損の 懸念から耐久性に問題があり、ベースの高さに制約を受けた。また、ガイド板５ も強度を高める結果、切削ドラムＡ′の重量増加に通じた。したがって、ビット ２の取付高さに自ずと限界があり、ガイド板５の突出長さもこれに比例した長さ に規制されてフトコロが小さくなった。この結果、ブレード６の突出長さも短な ものとなって、廃材の掻き上げが充分になされない欠点があった。さらには、フ トコロに廃材を抱えたまま路面切削機が走行することから、その分大きな動力を 必要とした。 In the conventional cutting drum A', when increasing the cutting depth, the height of the base 3 is increased. Along with this, the protruding length of the guide plate 5 has also been increased to create a so-called ``Fap'' that serves as a passage for waste materials. It was necessary to secure a large area. However, if base 3 is made higher, damage may occur. Due to concerns, there were problems with durability and restrictions were placed on the height of the base. In addition, the guide plate 5 Also, as a result of increasing the strength, the weight of the cutting drum A' increased. Therefore, bit There is naturally a limit to the mounting height of 2, and the protruding length of guide plate 5 is also proportional to this. Due to the regulation, the size of the foot has become smaller. As a result, the protruding length of the blade 6 is also shortened. There was a drawback that the scrap wood could not be scraped up sufficiently. Moreover, Since the road milling machine runs with waste material on its back, it requires a large amount of power. I needed it.
【０００５】 また、前記切削ドラムＡ′は廃材の送りを案内するためにガイド板５を複数備 える必要があり、部材点数が多くなるばかりかその取付作業や補修作業に多大な 手間を要した。[0005] Further, the cutting drum A' is equipped with a plurality of guide plates 5 for guiding the feeding of waste materials. Not only does it require a large number of parts, but it also requires a great deal of installation and repair work. It took a lot of effort.
【０００６】 この考案は前記問題点に鑑みてなされたもので、廃材を案内するためのガイド 板を不要にしつつも廃材の送りを可能にするとともに、切削ドラムの軽量化を図 り、しかも廃材の掻き上げ効率を向上する路面切削機の切削ドラムを提供するこ とを目的としている。[0006] This idea was made in view of the above problems, and is a guide for guiding waste materials. This makes it possible to feed waste materials while eliminating the need for plates, and also reduces the weight of the cutting drum. To provide a cutting drum for a road milling machine that improves waste material scraping efficiency. The purpose is to

この考案は前記問題点を解決するために、回転ドラムの外周にＶ字形に複数配 列される個別のベース上に、路面を切削するためのビットがホルダを介してそれ ぞれ取り付けられ、切削された廃材を回転ドラムの中心部で掻き上げるためのブ レードを備える路面切削機の切削ドラムにおいて、前記各列のベース同士を密接 に配設して各ベース間を溶接し、廃材の送りを案内するガイド壁とした路面切削 機の切削ドラムを構成したものである。 In order to solve the above-mentioned problem, this invention has been developed to arrange multiple parts in a V-shape around the outer circumference of the rotating drum. The bit for cutting the road surface is placed on a separate base in the column through the holder. A brush is attached to the rotary drum to scrape up the cut waste material in the center of the rotating drum. In the cutting drum of a road milling machine equipped with a blade, the bases of each row are closely connected to each other. The road surface is cut into a guide wall to guide the feeding of waste materials by welding between each base. This constitutes the cutting drum of the machine.

この考案の切削ドラムによると、ベース同士が溶接されてＶ字形に配列される ので、各列のベースが廃材の送りを案内するためのガイド壁となるため、従来の ガイド板が不要となる。また、ベースの高さを従来のものより高くしても、隣接 するベース同士を溶接して連結してあるので耐久性に不安はなく、ブレードの突 出長さも対応して掻き上げに充分な長さにできるので、効率的な掻き上げを可能 にする。 According to the cutting drum of this invention, the bases are welded together and arranged in a V-shape. Therefore, the base of each row serves as a guide wall to guide the feeding of waste materials, which is different from the conventional method. A guide plate is no longer required. In addition, even if the base height is higher than the conventional one, the adjacent The bases are welded together, so there is no need to worry about durability, and the blades do not protrude. The protrusion length can also be adjusted to a sufficient length for raking, allowing for efficient raking. Make it.

この考案に係る実施例を図面に基づいて説明する。図１は切削ドラムの側面図 、図２はベースの側面図、図３は切削ドラム外周面の展開図である。 An embodiment of this invention will be described based on the drawings. Figure 1 is a side view of the cutting drum. , FIG. 2 is a side view of the base, and FIG. 3 is a developed view of the outer peripheral surface of the cutting drum.
【００１０】 図２に示すように、ベース１３は側面視において直角を有する上辺が長い台形 であり、全体に略四角錐台を逆向きにした形状に形成されている。このベース１ ３を回転ドラム１０の外周にＶ字形に配設するに際し、図１および図３に示すよ うに隣接するベース１３の角部同士を突き合わせた密接状態に配設し、両ベース １３の角部を高さ方向にわたり溶接するものである。図示するように、隣接する ベース１３同士が連結されて一連となり、切削された廃材の送りを案内するため のガイド壁１５を構成する。このベース１３の上部にホルダ１４を溶接して、ピ ット１２を所定角度に向けて取り付けてある。符号１６は廃材を掻き上げるため のブレードである。0010 As shown in FIG. 2, the base 13 has a trapezoidal shape with a right angle and a long upper side when viewed from the side. It is generally formed in the shape of an inverted quadrangular pyramid. This base 1 3 in a V-shape around the outer periphery of the rotating drum 10, as shown in FIGS. 1 and 3. The corners of bases 13 adjacent to each other are arranged in close contact with each other, and both bases are 13 corners are welded in the height direction. Adjacent as shown The bases 13 are connected to form a series to guide the feeding of cut waste materials. The guide wall 15 is configured as follows. A holder 14 is welded to the top of this base 13, and the pin The cut 12 is attached so as to be oriented at a predetermined angle. Code 16 is for scraping up waste wood. It is a blade.
【００１１】 以上のように、ベース１３同士を溶接して連結し一連のガイド壁１５を構成し たので、従来例のように廃材の送りを案内する別部材のガイド板５（図４および 図５参照）を別途必要としない。したがって、部材点数が少なくなるのはもとよ り、多数あるガイド板５の取付，補修作業の必要がなくなる。また、この実施例 のように、ベース１３の高さを従来のものより高く形成すれば、いわゆるフトコ ロが大きくなって切削の深さも大きくなる。これにより、ブレード１６の突出長 さもビット１２の取り付け高さに相応して掻き上げに充分なより長いものが採用 でき、掻き上げ効率が向上するとともに、フトコロに廃材を抱えたまま走行する といった動力ロスが減少するものである。さらに、ベース１３は１個ずつ個別に 製造されたものであるので、ベース１３等が破損してもその部位の補修作業だけ ですむ。[0011] As described above, the bases 13 are welded and connected to form a series of guide walls 15. Therefore, as in the conventional example, a separate guide plate 5 (Fig. 4 and (see Figure 5) is not required separately. Therefore, not only does the number of parts decrease, but the number of parts decreases as well. This eliminates the need for mounting and repair work for a large number of guide plates 5. Also, this example If the height of the base 13 is made higher than the conventional one, the so-called footcoat As the diameter becomes larger, the depth of cutting also becomes larger. As a result, the protrusion length of the blade 16 is A longer one that is long enough for scraping is adopted in accordance with the mounting height of the bit 12. This improves raking efficiency and allows the machine to run with waste material held in the foot roller. This reduces power loss. Furthermore, each base 13 is individually Since it is a manufactured item, even if the base 13 etc. is damaged, only the repair work will be done on that part. That's fine.

この考案はベース同士を溶接で連結して一連のガイド壁を構成したので、廃材 の送りを案内するガイド板を設ける必要がない。したがって、部材点数が少なく なってガイド板の取付作業や補修作業の手間が掛からず、しかも切削ドラムの軽 量化が図れる。 With this idea, the bases were connected by welding to form a series of guide walls, so waste material could be There is no need to provide a guide plate to guide the feed. Therefore, the number of parts is small. This eliminates the trouble of installing and repairing guide plates, and also reduces the weight of the cutting drum. It can be quantified.
【００１３】 さらに、隣接するベース同士は溶接で連結されているので、ベースの高さを高 くしてフトコロを大きくしても、耐久性の問題はなくなり、したがってブレード も相応して廃材を掻き上げるのに充分な長さが得られるので、廃材を確実に掻き 上げることができ、しかもフトコロで廃材を抱えながら走行するといった動力ロ スも減少する。[0013] Furthermore, since adjacent bases are connected by welding, the height of the base can be increased. Even if you increase the width of the blade, there will be no durability issues, so the blade Correspondingly, sufficient length is obtained to rake up the waste material, so that the waste material can be raked reliably. It is a power engine that can be lifted up, and can also run while carrying waste materials with its foot roller. This also reduces the number of
