この考案は、強制空冷エンジン、特に冷却ファンに臨ま
せた吸気口に回転除塵板（わら切板）を設け、この回転
除塵板をカップを介して冷却ファンに連動連結したもの
に関する。[Detailed description of the invention] This invention is based on a forced air-cooled engine, in particular, a rotating dust removal plate (straw cutting plate) is installed at the intake port facing the cooling fan, and this rotating dust removal plate is interlocked and connected to the cooling fan via a cup. related to what was done.
従来、上記強制空冷エンジンでは、回転除塵板は溶接に
よってカップに固着しているので、比較的高価になるう
え、溶接がはずれて回転除塵板や導風カバーが破損する
ことがある等の難点がある。Conventionally, in the above-mentioned forced air-cooled engines, the rotating dust removal plate is fixed to the cup by welding, which is relatively expensive and has the disadvantage that the welding may come off and damage the rotating dust removal plate or air guide cover. be.
この考案は、上記の難点を解消するために提案されたも
のであって、その特徴とするところは、回転除塵板を冷
却ファンとこれに固着されるカップとで挾持するように
した点にある。This invention was proposed to solve the above-mentioned difficulties, and its feature is that the rotating dust removal plate is held between a cooling fan and a cup fixed to it. .
以下、本考案の実施例を刷面に基づき説明する。Hereinafter, embodiments of the present invention will be described based on the printed page.
第１図は強制空冷エンジンの横断平面図であり、符号１
はエンジン本体、２はフライホイールと一体に形成した
冷却ファンであり、冷却ファン２はエンジン本体１の前
側に突出したクランク軸３に固定しである。Figure 1 is a cross-sectional plan view of a forced air-cooled engine, with reference numeral 1.
2 is a cooling fan integrally formed with the engine body, and the cooling fan 2 is fixed to a crankshaft 3 protruding from the front side of the engine body 1.
エンジン本体１と冷却ファン２とを覆う導風ケース４に
は冷却ファン２と同軸状に吸風口５が開口してあり、こ
の吸風口５にカップ６が挿貫される。An air intake port 5 is opened coaxially with the cooling fan 2 in an air guide case 4 that covers the engine body 1 and the cooling fan 2, and a cup 6 is inserted into the air intake port 5.
カップ６の前側には始動用のりコイルプーリ７が配置さ
れ、リコイルプーリ７に枢支したラッチ爪８がカップ６
の吸入通風口９に係合することによって、リコイルプー
リ７で通風カップ６ないしクランク軸３を始動方向に１
駆動できるようになっている。A starting recoil pulley 7 is arranged on the front side of the cup 6, and a latch pawl 8 pivoted on the recoil pulley 7 is attached to the cup 6.
The recoil pulley 7 moves the ventilation cup 6 or the crankshaft 3 in the starting direction.
It can be driven.
符号１０は防塵カバーで、これはりコイルプーリ７、カ
ップ６および吸風口５を覆う。Reference numeral 10 denotes a dustproof cover, which also covers the coil pulley 7, cup 6, and air intake port 5.
カップ６の先端部には外つば状の受部１１が形成してあ
り、この受部１１と冷却ファン２の先端面とで回転除塵
板１２を挟持固定する。An outer brim-like receiving portion 11 is formed at the tip of the cup 6, and a rotary dust removal plate 12 is clamped and fixed between the receiving portion 11 and the tip end surface of the cooling fan 2.
っ回転除塵板１２は有孔板で形成しても無孔板で形成し
てもよいが、本例のようにカップ６の吸入通風口９が回
転除塵板１２で覆われる場合は、通風性のある有孔板で
形成する。The rotating dust removing plate 12 may be formed of a perforated plate or a non-perforated plate, but when the suction ventilation opening 9 of the cup 6 is covered with the rotating dust removing plate 12 as in this example, the ventilation It is formed from a perforated plate.
回転除塵板１２は、取付状態よりも若干長く形成し、カ
ップ取付ボルト１３の締込みにより弾性変形した状態で
取付けであるので、自己弾発力によって受部１１および
冷却ファン２に圧着する。The rotary dust removal plate 12 is formed to be slightly longer than the installed state, and is installed in an elastically deformed state by tightening the cup installation bolt 13, so that it is crimped to the receiving portion 11 and the cooling fan 2 by its self-resilient force.
また、回転除塵板１２の先端部をカップ６に外嵌し、そ
の一部の爪１６をカップ６の吸入通風口９に凹入嵌合さ
せて、回転除塵板１２とカップ６との相対回転を確実に
防止しである。Further, the tip of the rotary dust removing plate 12 is fitted onto the cup 6, and some of the claws 16 are recessedly fitted into the suction ventilation opening 9 of the cup 6, so that the relative rotation between the rotating dust removing plate 12 and the cup 6 is controlled. This is to reliably prevent this.
これにより、リコイルスタータの故障の際に、回転除塵
板１２の外周に別の始動ロープ（図外）を巻着けて始動
操作を行える。Thereby, in the event of a failure of the recoil starter, another starting rope (not shown) can be wrapped around the outer periphery of the rotating dust removal plate 12 to perform a starting operation.
符号１４はカップ６の排出通風口である。Reference numeral 14 is an exhaust vent of the cup 6.
第２図は本考案の別実流側を示し、これは、カップ６の
中間部に段付面よりなる受部１１を形成し、この受部１
１と冷却ファン２とて無孔板よりなる回転除塵板１２を
挾持する。FIG. 2 shows another actual flow side of the present invention, in which a receiving part 11 made of a stepped surface is formed in the middle part of the cup 6, and this receiving part 1
1 and a cooling fan 2 sandwich a rotating dust removal plate 12 made of a non-perforated plate.
リコイルスタータの故障に補える始動用ロープ１５はカ
ップ６の先端寄生部に巻掛けられるので、カップ６と回
転除塵板１２との相対回転は回転除塵板１２の自己弾発
力のみによって防止できる。Since the starting rope 15, which can compensate for failure of the recoil starter, is wrapped around the parasitic portion of the tip of the cup 6, relative rotation between the cup 6 and the rotating dust removing plate 12 can be prevented only by the self-resilient force of the rotating dust removing plate 12.
しかし、カップ６と回転除塵板１２との相対回転を確実
に防止するために、回転除塵板１２の内周縁から延出し
た爪１６をカップ６の排出通風口１４に係合しである。However, in order to reliably prevent relative rotation between the cup 6 and the rotary dust removing plate 12, a claw 16 extending from the inner peripheral edge of the rotating dust removing plate 12 is engaged with the exhaust vent 14 of the cup 6.
その他は前例と同様に構成しである。以上説明したよう
に、本考案は、回転除塵板をカップと冷却ファンとで挾
持するので、回転除塵板を外嵌したカップを冷却ファン
にボルト等で固定するだけで回転除塵板を確実に支持で
き、運転中に回転除塵板の固定点の一部が外れて回転除
塵板や導風ケースが破損することを防止できる。The rest of the structure is the same as the previous example. As explained above, in the present invention, the rotating dust removing plate is held between the cup and the cooling fan, so the rotating dust removing plate can be reliably supported by simply fixing the cup with the rotating dust removing plate fitted to the cooling fan with bolts, etc. This prevents damage to the rotating dust removing plate and the air guide case due to part of the fixing point of the rotating dust removing plate coming off during operation.
また、回転除塵板とカップとを溶接した従来のものに比
べると、組立て作業が簡単で安価に製造できる。Furthermore, compared to the conventional one in which the rotary dust removal plate and the cup are welded together, the assembly work is easier and the product can be manufactured at a lower cost.
