従来のこの除雪装置は、１つのエンジンからの駆動力によって、オーガとブロアの両方を回転させて、オーガで雪を中央部に集める作業と、ブロアで雪を上方へ飛ばす作業とを同時に行うため、エンジンに連結されたシャフトには非常に大きなトルクが掛かり、エンジンには非常に大きな負荷が掛かり、故障が発生し易い。また、高出力のエンジンを使用しなければならないので、コストも掛かってしまう。また、この除雪装置は除雪専用の装置であり、冬期以外には、エンジン等を含む装置を活用できない。 This conventional snow removal device rotates both the auger and the blower by the driving force from one engine and collects the snow in the center with the auger and the work to blow the snow upward with the blower at the same time. A very large torque is applied to the shaft connected to the engine, a very large load is applied to the engine, and a failure is likely to occur. In addition, since a high-power engine must be used, the cost is increased. Further, this snow removal device is a device dedicated to snow removal, and devices including an engine or the like cannot be used except during the winter season.

そこで、本発明は、エンジンに大きな負荷を掛けずに除雪でき、かつ、除雪作業以外の他の用途で使用する機械を用いて除雪作業を行うことができる除雪装置を提供することを目的とする。 Therefore, an object of the present invention is to provide a snow removal device that can remove snow without applying a large load to the engine and can perform snow removal using a machine that is used for other purposes than snow removal. .

A hand-held type brush cutter having a rotation transmission portion to which a grass cutting blade is detachably attached, and a snow removal member that is detachably attached to a tip of the holding rod, and the snow removal member has a horizontal axis through the rotation transmission portion. It rotates around and immediately Bei the shoveling rotator fly scratching snow, the snow removal member includes a shaft member that rotates with the horizontal axis around mounted on a rotating shaft of the rotation transmission portion, of the holding rod comprises a housing member attached to the tip provided at the rear vicinity of the shovel rotating body induces snow該雪scraping rotating body scratched upwards, the said shoveling rotating body, plug fitted around the said shaft member It has a hole and the shaft member and the horizontal It consists of three or more short rotary body rotating integrally with the heart around, moreover, short-rotation body includes a disc portion having the insertion hole at the center are arranged in parallel at predetermined intervals, a pair of circular A snow scraping blade integrally formed so as to connect the inner surface of the plate portion, and the housing member is a snow throwing wall that guides the snow formed upward in a substantially J shape having an upwardly inclined shape in the transverse section upward parts and, possess and snow scooping edge portion formed integrally along the lower edge of-projecting Yukikabe portion, and further, one end is detachably attached to the holding rod, the other end the housing member A rotation lever that is detachably attached to the rear portion and fixes the direction of the snow removal member, wherein the angle formed between the axis of the holding rod and the horizontal axis is set to an obtuse angle, and the rotation transmission Ru der which the rotating shaft parts were freely vertically and horizontally switching.

本発明は、次のような著大な効果を奏する。
本発明に係る除雪装置は、草刈刃が着脱自在な回転伝達部を先端に有する保持杆を備えた手押式刈払機の、保持杆の先端に着脱自在に取付けられる除雪部材を備えるので、回転伝達部に取付けた草刈刃を除雪部材に交換することで、１台の手押式刈払機を、夏場は草刈専用として、また、冬場は除雪用として用いることができ、エンジンや車輪等を有する手押式機械を多用途に有効利用できる。そして、草刈刃と除雪部材を回転伝達部に取付・取外するだけで使用用途を換えることができるので、交換作業に手間が掛からず至便である。また、草刈専用機と除雪専用機を夫々購入する必要がないので、経費の削減も図ることができる。
また、除雪部材は、回転伝達部に取付けられ水平軸心廻りに回転する軸部材と、軸部材に外嵌される複数の短回転体から成る雪掻き回転体とを有し、これらの短回転体が、夫々の雪掻き羽根が周方向において位相が相互にずれるように、軸部材に外嵌されて雪掻き回転体を構成するので、夫々の短回転体の雪掻き羽根が積雪に接近するタイミングがずれるため、全ての短回転体の雪掻き羽根が同時に雪を掻くことがない。従って、雪を掻く瞬間に回転伝達部が受けるトルクは、雪掻き羽根が軸心方向の全長にわたって同時に積雪を掻くものに比べて、３分の１程度となり、エンジンに掛かる負荷が大幅に低減される。よって、雪掻き回転体がスムーズに回転し、効率よく除雪作業を行うことができると共に、エンジン等の故障を抑えることができる。
また、雪掻き回転体を全て一体として製造する場合、金型の製造コストが非常に掛かり、しかも、金型を高精度にするのが非常に困難であるが、複数の短回転体に分割することで、金型のコストも大幅に低減でき、高精度の金型を製造できる。 The present invention has the following remarkable effects.
The snow removal device according to the present invention includes a snow removal member that is detachably attached to the tip of the holding rod of the hand-held type brush cutter having a holding rod having a rotation transmitting portion at the tip of which the grass cutting blade is detachable. By replacing the mowing blade attached to the transmission part with a snow removal member, one hand-held type brush cutter can be used exclusively for mowing in the summer and for snow removal in the winter, and has an engine, wheels, etc. A hand-held machine can be used effectively for many purposes. Since the usage can be changed simply by attaching / removing the grass cutting blade and the snow removal member to / from the rotation transmitting portion, the replacement work is not troublesome and convenient. In addition, since it is not necessary to purchase a mowing machine and a snow removal machine, the cost can be reduced.
The snow removal member includes a shaft member that is attached to the rotation transmission unit and rotates around a horizontal axis, and a snow scraping rotator that includes a plurality of short rotators that are externally fitted to the shaft member. However, since the snow scraping blades are externally fitted to the shaft members so that the respective snow scraping blades are out of phase with each other in the circumferential direction, the timing of the snow scraping blades of the respective short rotating members approaching the snow is shifted. , All of the short-spinning snow scraping blades do not scratch the snow at the same time. Accordingly, the torque received by the rotation transmission unit at the moment of scraping snow is about one third of that of the snow scraping blade that simultaneously scrapes snow over the entire axial length, and the load on the engine is greatly reduced. . Therefore, the snow scraping rotating body rotates smoothly, snow removal work can be performed efficiently, and failure of the engine or the like can be suppressed.
In addition, when manufacturing all of the snow rotator as a single unit, the manufacturing cost of the mold is very high, and it is very difficult to make the mold highly accurate, but it must be divided into a plurality of short rotators. Thus, the cost of the mold can be greatly reduced, and a highly accurate mold can be manufactured.

また、軸部材の外周面と、各短回転体の差込孔部を正六角形状に形成されているので、例えば、３つの短回転体を、120 °ずつ位相をずらして軸部材に外嵌することができる。そして、同一形状の短回転体を製造すればよく、コストも削減できる。
また、雪掻き羽根が掬った雪を、Ｊ字状のハウジング部材によって、前方上方へ誘導して飛ばすことができるので、シンプルな構成でありながら、雪を遠方へ飛ばすことができて、スムーズに除雪を行うことができる。さらに、ハウジング部材の雪掬い辺部が、地表上に積もった雪に食い込んで掬うため、雪をスムーズに雪掻き回転体へ送ることができ、除雪を効率よく行うことができる。また、ハウジング部材は、投雪壁部と雪掬い辺部とが一体に形成されているので、別部材として製造してボルトナット結合等で一体にするものに比べて、手間が掛からず、使用中にボルトナット結合等が緩んで分離する虞れがなく頑強な構造にできる。 In addition, since the outer peripheral surface of the shaft member and the insertion hole portion of each short rotator are formed in a regular hexagon shape, for example, three short rotators are externally fitted to the shaft member with a phase shift of 120 °. can do. Then, it is sufficient to manufacture a short rotating body having the same shape, and the cost can be reduced.
In addition, the snow swept by snow scraping blades can be guided and blown forward by the J-shaped housing member, so that the snow can be blown far away with a simple structure, and snow can be removed smoothly. It can be performed. Furthermore, since the snow scooping side portion of the housing member bites into the snow accumulated on the ground surface, the snow can be smoothly sent to the snow scraping rotating body, and snow removal can be performed efficiently. Also, the housing member has a snow throwing wall part and a snow scooping side part formed integrally, so it takes less time and effort compared to one that is manufactured as a separate member and integrated with bolts and nuts etc. There is no fear that the bolts and nuts are loosened and separated, making it a robust structure.

The rotation transmission unit 9 has a gear case 18 provided at the tip 5 a of the holding rod 5, and the gear in the engine 6 and the gear case 18 is attached to a drive shaft that is rotatably disposed inside the holding rod 5. Thus, the rotary shaft portion 19 is rotatably projected from the mounting disk portion 17 of the gear case 18. Reference numeral 42 denotes a spherical blade height setting tool which is attached in the middle of the holding rod 5 and keeps the height of the mowing blade constant.
When used as a hand-held type brush cutter 40 for mowing, the rotational axis of the rotary shaft portion 19 is oriented in a substantially vertical direction, and a mowing blade is attached (not shown). FIG. 1 shows a state in which the cutting blade is removed from the rotation transmission unit 9, the rotation axis of the rotation shaft unit 19 is set in the horizontal axis L direction, and the snow removal member 4 is attached to the rotation transmission unit 9. Show.

次に、除雪部材４について説明すると、除雪部材４は、回転伝達部９の回転軸部19に取付けられ水平軸心Ｌ廻りに回転する軸部材２と、回転伝達部９を介して（軸部材２に外嵌されて）水平軸心Ｌ廻りに回転して雪を掻き飛ばす雪掻き回転体１と、保持杆５の先端５ａに取付けられ雪掻き回転体１の後方近傍に設けられて雪掻き回転体１が掻いた雪を上方遠方へ飛ぶように誘導するハウジング部材３と、を備える。 Next, the snow removal member 4 will be described. The snow removal member 4 is attached to the rotation shaft portion 19 of the rotation transmission portion 9 and rotates around the horizontal axis L via the rotation transmission portion 9 (shaft member). And a snow scraping rotary body 1 that rotates around the horizontal axis L and scrapes off the snow, and a snow scraping rotary body 1 that is attached to the front end 5a of the holding rod 5 and is provided near the rear of the snow scraping rotary body 1. A housing member 3 for guiding the scratched snow to fly upward and far away.

先ず、図３〜図６，図11に於て、軸部材２は、正六角筒状のパイプ部材21と、パイプ部材21の一端21ａに嵌着され回転伝達部９の回転軸部19が螺着される雌ネジ孔22ａを有する取付端部材22と、パイプ部材21の他端21ｂに嵌着され長手方向（軸心Ｌ方向）へ突設された軸部23ａを有する軸端部材23と、を有する。また、パイプ部材21の他端21ｂと軸端部材23には、差込孔24が径方向に貫設されていて、軸部材２に雪掻き回転体１を外嵌した後で、差込孔24に位置ずれ防止ピン25を差込めば、回転体１の軸心Ｌ方向への移動を防ぐことができる（図３参照）。なお、回転体１及び軸部材２の回転方向50は前回りの方向であり、軸心Ｌ方向左側から見て反時計回りである。 First, in FIGS. 3 to 6 and 11, the shaft member 2 is fitted to a regular hexagonal tubular pipe member 21 and one end 21 a of the pipe member 21, and the rotation shaft portion 19 of the rotation transmitting portion 9 is screwed. A mounting end member 22 having a female screw hole 22a to be attached; a shaft end member 23 having a shaft portion 23a fitted in the other end 21b of the pipe member 21 and projecting in the longitudinal direction (axial center L direction); Have The other end 21b of the pipe member 21 and the shaft end member 23 are provided with insertion holes 24 extending in the radial direction. After the snow scraping rotor 1 is externally fitted to the shaft member 2, the insertion holes 24 are inserted. If the misalignment prevention pin 25 is inserted into the rotary body 1, the movement of the rotating body 1 in the direction of the axis L can be prevented (see FIG. 3). The rotating direction 50 of the rotating body 1 and the shaft member 2 is the forward direction, and is counterclockwise when viewed from the left side in the axis L direction.

次に、図１，図３〜図７に於て、雪掻き回転体１は、水平軸心Ｌ廻りに軸部材２と一体回転する３つの短回転体10…から成る。換言すれば、雪掻き回転体１は、軸心Ｌ方向に、３つの短回転体10…に分割される。
各短回転体10は、所定間隔をもって平行に配設され中央に差込孔部12，12を有する円板部14，14と、円板部14，14の差込孔部12，12から内側に一体に折曲られた正六角筒状の短筒部13，13と、一対の円板部14，14の内面14ａ，14ａを連結するよう一体に形成され周方向Ｘに所定ピッチで配設される４つの雪掻き羽根11…と、を有する。差込孔部12は、軸部材２に略隙間無く外嵌可能な正六角形状に形成される。雪掻き羽根11の等分配中心角度θ₁₁────図例では90°────と、軸部材２を短回転体10の差込孔部12に差込む入替ピッチ角度θ₁₂────図例では60°────とを、相違させ、かつ、相互に整数倍とならないように設定する。 1 to 3, the snow scraping rotating body 1 is composed of three short rotating bodies 10 that rotate integrally with the shaft member 2 around the horizontal axis L. In other words, the snow scraping rotary body 1 is divided into three short rotary bodies 10 in the axial center L direction.
Each short rotating body 10 is arranged in parallel with a predetermined interval and has a disc portion 14, 14 having an insertion hole portion 12, 12 in the center, and an inner side from the insertion hole portion 12, 12 of the disc portion 14, 14. Are integrally formed so as to connect the regular hexagonal cylindrical short tube portions 13 and 13 and the inner surfaces 14a and 14a of the pair of disc portions 14 and 14 and arranged at a predetermined pitch in the circumferential direction X. And four snow scraping blades 11. The insertion hole portion 12 is formed in a regular hexagonal shape that can be fitted to the shaft member 2 without a substantial gap. Equidistribution center angle θ _{11 of} snow scraping blade 11 ────In the example of the figure, 90 ° ──── and replacement pitch angle θ _{12 for} inserting shaft member 2 into insertion hole 12 of short rotating body 10 ─── ─In the example of the figure, set 60 ° ──── different from each other and not to be an integral multiple of each other.

各雪掻き羽根11は、帯板材を折曲部をもって横断面くの字（Ｌ字）状に折曲げた形状を有し、折曲辺を介して回転方向50における先頭側の一（前）帯板部15と後側の他（後）帯板部16とから成る。一帯板部15は他帯板部16よりも短く、かつ、外径方向Ｒに対し各帯板部15，16が拡開するように配設される。かつ、一帯板部15の端縁部15ａは円板部14の外周縁から所定間隔をもって離間し、かつ、他帯板部16の端縁部16ａは円板部14の外周縁に接するまで延設されている。これにより、雪掻き回転体１（短回転体10）が回転して雪掻き羽根11が雪Ｓを掻く際に、前側の帯板部15が雪Ｓを掻かずに通過し、その直後に、後側の帯板部16が積雪Ｓを掻くので（図６参照）、各雪掻き羽根11が雪Ｓを確実に掬う。また、複数のリブ13ａ…が、短筒部13の外周から円板部14の内面14ａにかけて、所定ピッチで形成されており、短回転体10は強固な構造となる。
そして、３つの短回転体10…は、相互に円板部14…同士が密着状として、かつ、３つの短回転体10…の雪掻き羽根11…の位置が相互に周方向Ｘに 120°ずつずれるように、軸部材２に外嵌される（図３〜図６参照）。 Each snow scraping blade 11 has a shape obtained by bending a band plate material into a U-shaped (L-shaped) cross section with a bent portion, and the first (front) band on the leading side in the rotation direction 50 through the bent side. It consists of a plate part 15 and another (rear) band plate part 16 on the rear side. The one band plate portion 15 is shorter than the other band plate portion 16 and is arranged so that the respective band plate portions 15 and 16 expand in the outer diameter direction R. In addition, the edge 15a of the one band plate 15 is spaced from the outer peripheral edge of the disk part 14 with a predetermined interval, and the edge 16a of the other band plate 16 extends until it contacts the outer peripheral edge of the disk part 14. It is installed. Thereby, when the snow scraping rotating body 1 (short rotating body 10) rotates and the snow scraping blade 11 scratches the snow S, the front strip 15 passes through the snow S without scratching, and immediately after that, the rear side Since the strip plate portion 16 scratches the snow accumulation S (see FIG. 6), each snow scraping blade 11 reliably crawls the snow S. A plurality of ribs 13a are formed at a predetermined pitch from the outer periphery of the short cylindrical portion 13 to the inner surface 14a of the disc portion 14, and the short rotating body 10 has a strong structure.
The three short rotators 10 are in close contact with each other, and the positions of the snow scraping blades 11 of the three short rotators 10 are 120 ° in the circumferential direction X. The shaft member 2 is externally fitted so as to be displaced (see FIGS. 3 to 6).

図13は本発明に係る除雪装置の他の実施の形態を示し、車輪７が、図１のものと相違して、ブロー成型により形成された小型の中空樽型（殻構造）を有し、刃高設定具42の大きさと同程度の大きさに形成されている。なお、図１の刈払機40の車輪７は、刃高設定具42よりも大きな径を有するタイヤ形状に成形されており、図示省略されているが、接地面に滑り止め用凹凸を形成してもよい。また、図１，図13の両装置は、車輪７の左右両側に、一対の補助輪が配設される。
そして、図13に於て、手押式刈払機40を草刈用として使用される場合、保持杆５に刃高設定具42、ガード部材43が取付けられると共に、回転伝達部９の回転軸部（図示省略）は鉛直方向に向けられて、草刈刃44が取付けられる（二点鎖線で示した状態）。ガード部材43は、草が使用者側に飛来するのを防ぐためのもので、刃高設定具42の前方にて保持杆５に着脱自在に取付けられる。
次いで、刈払機40を除雪用に使用する場合には、保持杆５・回転伝達部９からガード部材43・草刈刃44を取外し（矢印51参照）、そして、回転伝達部９の回転軸部を水平方向に向け、回転伝達部９に固定杆部材26・除雪部材４を取付ける（矢印52参照）。
なお、図１の手押式刈払機40に於ても、草刈用に使用する場合は、保持杆５・回転伝達部９にガード部材・草刈刃が取付けられており（図示省略）、除雪用として使用する場合に、図13で上述したのと同様の手順で交換作業を行う。 FIG. 13 shows another embodiment of the snow removal device according to the present invention, and the wheel 7 has a small hollow barrel shape (shell structure) formed by blow molding, unlike that of FIG. The blade height setting tool 42 is formed in the same size as the size. The wheel 7 of the brush cutter 40 in FIG. 1 is formed in a tire shape having a larger diameter than the blade height setting tool 42 and is not shown in the figure, but has anti-slip irregularities formed on the ground contact surface. Also good. 1 and 13 are provided with a pair of auxiliary wheels on the left and right sides of the wheel 7.
In FIG. 13, when the hand-held type brush cutter 40 is used for mowing, the blade height setting tool 42 and the guard member 43 are attached to the holding rod 5, and the rotation shaft portion ( (Not shown) is oriented in the vertical direction, and the mowing blade 44 is attached (a state indicated by a two-dot chain line). The guard member 43 is for preventing grass from flying to the user side, and is detachably attached to the holding rod 5 in front of the blade height setting tool 42.
Next, when the brush cutter 40 is used for snow removal, the guard member 43 and the mowing blade 44 are removed from the holding rod 5 and the rotation transmission portion 9 (see arrow 51), and the rotation shaft portion of the rotation transmission portion 9 is removed. The fixed rod member 26 and the snow removal member 4 are attached to the rotation transmitting portion 9 in the horizontal direction (see arrow 52).
In the hand-held type brush cutter 40 in FIG. 1, when used for mowing, a guard member and a mowing blade are attached to the holding rod 5 and the rotation transmission portion 9 (not shown). , The replacement operation is performed in the same procedure as described above with reference to FIG.

そして、図１〜図６，図10に於て、手押式刈払機40のエンジン６を始動させると、回転伝達部９の回転軸部19に接続された軸部材２・雪掻き回転体１が水平軸心Ｌ廻りに矢印50のように前方向に回転する。そして、ハンドル41を持って刈払機40を前進させると、雪掬い辺部33の掬い縁部37が地表上の積雪Ｓを掬い、かつ、掬われた雪Ｓが前方下傾状掬い部33ｂを滑り上がり、雪Ｓはスムーズに雪掻き回転体１へ送られる。
そして、上述のように、雪掻き回転体１を成す３つの短回転体10…は、夫々の雪掻き羽根11…の位置が相互に周方向Ｘに 120°ずつずれた状態で、一体に回転するので（図４〜図６参照）、各雪掻き羽根11が雪Ｓを掻くタイミングが、夫々の短回転体10において120 °周期でずれるため、全ての短回転体10…の雪掻き羽根11…が同時に雪Ｓを掻くことがない。従って、雪Ｓを掻くときに短回転体10及び軸部材２が受けるトルクは、雪掻き羽根が軸心方向の全長にわたって雪Ｓを掻くものに比べて、３分の１程度となり、エンジン６に掛かる負荷が大幅に低減される。
また、電動除雪機と違い、電源コードの届かない場所でも除雪作業をできる。しかも、積雪量に応じて、エンジンの回転数を変えることで、雪掻き回転体１の回転数を変ることができるので、ギアボックスを除雪部材４に設ける必要がなく部品点数が少ない。 1 to 6 and 10, when the engine 6 of the hand-held brush cutter 40 is started, the shaft member 2 and the snow scraping rotator 1 connected to the rotating shaft portion 19 of the rotation transmitting portion 9 are Around the horizontal axis L, it rotates forward as indicated by the arrow 50. Then, when the brush cutter 40 is moved forward with the handle 41, the scooping edge 37 of the snow scooping side 33 scoops the snow cover S on the surface, and the scooped snow S pushes the scooping scooping part 33b forward and downward. After sliding up, the snow S is smoothly sent to the snow scraping rotor 1.
As described above, the three short rotating bodies 10 constituting the snow scraping rotating body 1 rotate integrally with the positions of the respective snow scraping blades 11 being shifted from each other by 120 ° in the circumferential direction X. (See FIGS. 4 to 6), the timing at which each snow scraping blade 11 scrapes the snow S is shifted by a period of 120 ° in each short rotating body 10, so that the snow scraping blades 11 of all the short rotating bodies 10. S is not scratched. Therefore, the torque received by the short rotating body 10 and the shaft member 2 when scraping the snow S is about one third that of the snow scraping blade scratching the snow S over the entire length in the axial direction, and is applied to the engine 6. The load is greatly reduced.
Also, unlike an electric snowblower, snow removal can be performed even in places where the power cord does not reach. Moreover, since the rotational speed of the snow scraping rotating body 1 can be changed by changing the rotational speed of the engine in accordance with the amount of snow, the gear box need not be provided in the snow removal member 4 and the number of parts is small.

そして、雪掻き羽根11が掬った雪Ｓは、雪掻き羽根11がハウジング部材３の投雪壁部31の弯曲板部31ａに対応する位置にあるときには、弯曲板部31ａにより、雪掻き羽根11に掬われた状態で保持されており、雪掻き羽根11が頂部近傍まで達すると、投雪壁部31の平板部31ｂの前面に沿って滑りつつ前方上傾方向へ飛び出していく（図10の矢印28参照）。また、両側壁部35, 35のガードにより雪が側方へ飛散することもない。このように、ハウジング部材３によって、雪を前方上傾の一定方向に誘導して飛ばすことができる。
なお、図１，図２の除雪部材４は前方より僅かに左側を向くように取付けられているが、設計変更自由であり、僅かに右側を向けたり、真正面に向くように取付けてもよい。また、除雪部材４は、回転伝達部９がハウジング部材３の左側壁部35Ａに取付けられるように形成されているが、除雪部材４の全体の構造を左右逆として、回転伝達部９が右側壁部35Ｂに取付けられるように形成してもよい（図示省略）。
また、本発明に於ては、雪掻き回転体１を３つの短回転体10…から構成しているが、雪掻き回転体１の全長に応じて、４つ以上の短回転体10…から構成するのもよい。
なお、図１，図13に於て、刈払機40に装着された刃高設定具42により、保持杆５の先端５ａが前後だけでなく、左右にも大きく、かつ、軽く振れるので、左右へ────ほうきで掃くように、────巾広く効率良く除雪できる。 When the snow scraping blade 11 is in a position corresponding to the curved plate portion 31a of the snow throwing wall portion 31 of the housing member 3, the snow S swung by the snow scraping blade 11 is beaten by the snow scraping blade 11 by the curved plate portion 31a. When the snow scraping blade 11 reaches the vicinity of the top portion, it slides out along the front surface of the flat plate portion 31b of the snow throwing wall portion 31 and jumps out in the upward upward direction (see arrow 28 in FIG. 10). . Moreover, snow is not scattered sideways by the guards of the side wall portions 35, 35. In this manner, the housing member 3 can guide and fly snow in a certain direction that is inclined forward and upward.
The snow removal member 4 in FIGS. 1 and 2 is attached so that it faces slightly to the left from the front, but the design can be changed freely, and it may be attached so that it faces slightly to the right or directly in front. Further, the snow removal member 4 is formed so that the rotation transmitting portion 9 is attached to the left side wall portion 35A of the housing member 3, but the entire structure of the snow removing member 4 is reversed left and right, and the rotation transmitting portion 9 is disposed on the right side wall. You may form so that it may attach to the part 35B (illustration omitted).
Further, in the present invention, the snow scraping rotator 1 is composed of three short rotators 10. However, the snow scraping rotator 1 is composed of four or more short rotators 10. It's also good.
1 and 13, the blade height setting tool 42 attached to the brush cutter 40 causes the tip 5a of the holding rod 5 to swing not only forward and backward, but also from side to side and lightly. ──── You can remove snow widely and efficiently just like sweeping with a broom.

以上のように、本発明に係る除雪装置は、エンジン６と車輪７とがフレーム８に取付けられエンジン６から前方下傾方向へ延設された保持杆５の先端５ａにエンジン６の回転駆動力が伝えられ草刈刃が着脱自在な回転伝達部９を有する手押式刈払機40の、保持杆５の先端５ａに着脱自在に取付けられる除雪部材４を備え、除雪部材４は、回転伝達部９を介して水平軸心Ｌ廻りに回転して雪を掻いて飛ばす雪掻き回転体１を具備するので、回転伝達部９に取付けた草刈刃を除雪部材４に交換することで、１台の手押式刈払機40を、夏場は草刈専用として、また、冬場は除雪用として用いることができ、エンジン６や車輪７等を有する手押式機械を多用途に有効利用できる。そして、草刈刃と除雪部材４を回転伝達部９に取付・取外するだけで使用用途を換えることができるので、交換作業に手間が掛からず至便である。また、草刈専用機と除雪専用機を夫々購入する必要がないので、購入経費の削減も図ることができる。 As described above, in the snow removal device according to the present invention, the rotational driving force of the engine 6 is applied to the front end 5a of the holding rod 5 in which the engine 6 and the wheels 7 are attached to the frame 8 and extend from the engine 6 in the forward and downward tilt direction. Is provided with a snow removal member 4 detachably attached to the tip 5a of the holding rod 5 of the hand-held type brush cutter 40 having the rotation transmission portion 9 to which the mowing blade is detachably attached. The snow removal member 4 includes the rotation transmission portion 9 Since a snow scraping rotating body 1 that rotates around the horizontal axis L through the blade and scrapes and blows snow is provided, by replacing the mowing blade attached to the rotation transmitting portion 9 with the snow removing member 4, one hand The brush cutter 40 can be used exclusively for mowing in the summer and for snow removal in the winter. A hand-held machine having the engine 6 and the wheels 7 can be effectively used for various purposes. Since the usage can be changed simply by attaching / removing the grass cutting blade and the snow removal member 4 to / from the rotation transmitting portion 9, the replacement work is not troublesome and convenient. In addition, since it is not necessary to purchase a mowing machine and a snow removal machine, the purchase cost can be reduced.

また、本発明に係る除雪装置は、エンジン６と車輪７とがフレーム８に取付けられエンジン６から前方下傾方向へ延設された保持杆５の先端５ａに取付けられる除雪部材４を備え、除雪部材４は、保持杆５の先端５ａに設けられエンジン６の回転駆動力が伝えられる回転伝達部９を介して水平軸心Ｌ廻りに回転して雪を掻いて飛ばす雪掻き回転体１を具備するので、回転伝達部９に取付けた草刈刃を除雪部材４に交換することで、エンジン６や車輪７等から成る装置を、夏場は草刈専用として、また、冬場は除雪用として多用途に有効利用できる。そして、草刈刃と除雪部材４を回転伝達部９に取付・取外するだけで使用用途を換えることができるので、交換作業に手間が掛からず至便である。また、草刈専用機と除雪専用機を夫々購入する必要がないので、購入経費の削減も図ることができる。 Further, the snow removal device according to the present invention includes a snow removal member 4 attached to a tip 5a of a holding rod 5 in which an engine 6 and wheels 7 are attached to a frame 8 and extended from the engine 6 in a forward and downward tilt direction. The member 4 includes a snow scraping rotator 1 that rotates around a horizontal axis L through a rotation transmitting portion 9 that is provided at the tip 5a of the holding rod 5 and transmits the rotational driving force of the engine 6 to scrape and fly snow. Therefore, by replacing the mowing blade attached to the rotation transmission part 9 with the snow removing member 4, the device composed of the engine 6, wheels 7, etc. can be effectively used for a variety of purposes only for mowing in the summer and for snow removal in the winter. it can. Since the usage can be changed simply by attaching / removing the grass cutting blade and the snow removal member 4 to / from the rotation transmitting portion 9, the replacement work is not troublesome and convenient. In addition, since it is not necessary to purchase a mowing machine and a snow removal machine, the purchase cost can be reduced.

また、除雪部材４は、回転伝達部９に取付けられ水平軸心Ｌ廻りに回転する軸部材２と、保持杆５の先端５ａに取付けられ雪掻き回転体１の後方近傍に設けられて雪掻き回転体１が掻いた雪を上方へ誘導するハウジング部材３と、を備え、かつ、雪掻き回転体１は、軸部材２に外嵌する差込孔部12を有し軸部材２と水平軸心Ｌ廻りに一体に回転する複数の短回転体10から成り、かつ、各短回転体10は、周方向Ｘに所定ピッチで付設された複数の雪掻き羽根11を有し、かつ、複数の短回転体10を、周方向Ｘにおいて雪掻き羽根11が相互にずれるように、隣接して軸部材２に外嵌して、雪掻き回転体１が構成されるので、複数の短回転体10…の雪掻き羽根11が積雪Ｓに接近するタイミングがずれるため、全ての短回転体10…の雪掻き羽根11が同時に雪Ｓを掻くことがない。従って、例えば、短回転体10…を３つに分割すれば、雪Ｓを掻くときに回転伝達部９が受けるトルクは、雪掻き羽根が軸心方向の全長にわたって同時に積雪Ｓを掻くものに比べ、３分の１程度となり、エンジン６に掛かる負荷が大幅に低減される。よって、雪掻き回転体１がスムーズに回転し、効率よく除雪作業を行うことができると共に、エンジン６等の故障を抑えることができる。
また、雪掻き回転体１を全て一体として製造する場合、金型のコストが非常に掛かり、しかも、金型を高精度にするのが非常に困難であるが、複数の短回転体10…に分割することで、金型のコストが大幅に低減され、高精度の金型を製造できる。
また、雪掻き羽根11が掬った雪を、ハウジング部材３によって、前方上方へ誘導して飛ばすことができるので、スムーズに除雪を行うことができる。 Further, the snow removal member 4 is attached to the rotation transmission unit 9 and rotates around the horizontal axis L, and is attached to the front end 5a of the holding rod 5 and is provided in the vicinity of the rear of the snow scraping rotator 1, and the snow scraping rotator. 1 and a housing member 3 for guiding the scraped snow upward, and the snow scraping rotating body 1 has an insertion hole portion 12 fitted around the shaft member 2 and around the shaft member 2 and the horizontal axis L. And each of the short rotators 10 has a plurality of snow scraping blades 11 attached at a predetermined pitch in the circumferential direction X, and the plurality of short rotators 10 Are fitted on the shaft member 2 adjacently so that the snow scraping blades 11 are displaced from each other in the circumferential direction X, and the snow scraping rotating body 1 is configured. Since the timing of approaching the snow cover S is shifted, the snow scraping blades 11 of all the short rotating bodies 10. It will not be scratching. Therefore, for example, if the short rotating body 10 is divided into three parts, the torque received by the rotation transmission unit 9 when scraping the snow S is compared to that the snow scraping blade scrapes the snow accumulation S at the same time over the entire length in the axial direction. The load on the engine 6 is greatly reduced. Therefore, the snow scraping rotator 1 rotates smoothly, snow removal work can be performed efficiently, and failure of the engine 6 and the like can be suppressed.
Further, when the snow scraping rotating body 1 is manufactured as a whole, the cost of the mold is very high, and it is very difficult to make the mold highly accurate, but it is divided into a plurality of short rotating bodies 10. By doing so, the cost of the mold is greatly reduced, and a highly accurate mold can be manufactured.
Further, since the snow struck by the snow scraping blade 11 can be guided and blown forward and upward by the housing member 3, snow can be removed smoothly.

また、軸部材２は断面正六角形の外周面20を有し、かつ、各短回転体10の差込孔部12は、軸部材２に略隙間無く外嵌可能な正六角形状に形成されているので、同じ形状の（同じ配置で雪掻き羽根11…を具備する）複数の短回転体10…を、夫々の雪掻き羽根11が周方向Ｘに位相がずれるように軸部材２に外嵌することができる。よって、例えば、３つの短回転体10…を、120 °ずつ位相をずらして軸部材２に外嵌することも可能となる。そして、雪掻き羽根11の配置が異なる短回転体10を製造する必要がないので、製造コストも削減できる。 Further, the shaft member 2 has an outer peripheral surface 20 having a regular hexagonal cross section, and the insertion hole portion 12 of each short rotating body 10 is formed in a regular hexagonal shape that can be fitted to the shaft member 2 with almost no gap. Therefore, a plurality of short rotating bodies 10 having the same shape (including the snow scraping blades 11 having the same arrangement) are externally fitted to the shaft member 2 so that the respective snow scraping blades 11 are out of phase in the circumferential direction X. Can do. Therefore, for example, the three short rotators 10 can be externally fitted to the shaft member 2 with phases shifted by 120 °. And since it is not necessary to manufacture the short rotary body 10 in which the arrangement | positioning of the snow scraping blade 11 differs, manufacturing cost can also be reduced.

また、ハウジング部材３は、横断面上方前傾状の略Ｊの字に形成された雪を上方へ誘導する投雪壁部31と、投雪壁部31の下端縁32に沿って一体に形成された雪掬い辺部33と、を有するので、刈払機40を前進させると、雪掬い辺部33が地表上に積もった雪に食い込んで掬うため、雪をスムーズに雪掻き回転体１へ送ることができ、除雪を効率よく行うことができる。
また、各短回転体10の回転に伴い、雪掻き羽根11に掬われた雪が、ハウジング部材３の投雪壁部31の前面に沿って誘導されるので、雪を、前方上傾方向へ遠くに飛ばすことができ、除雪作業をスムーズに行うことができる。
また、ハウジング部材３は、投雪壁部31と雪掬い辺部33とが一体に形成されているので、別部材として製造してボルトナット結合等で一体にするものに比べて、手間が掛からず、使用中にボルトナット結合等が緩んで分離する虞れがなく頑強な構造にできる。 Further, the housing member 3 is integrally formed along a snow throwing wall portion 31 for guiding the snow formed upward in a substantially J-shape having a forwardly inclined shape in the cross section along the lower end edge 32 of the snow throwing wall portion 31. Therefore, when the brush cutter 40 is moved forward, the snow crawl side 33 bites into the snow piled up on the ground surface, so that the snow is smoothly sent to the snow scraping rotator 1. And can remove snow efficiently.
Further, as the short rotator 10 rotates, the snow scooped by the snow scraping blades 11 is guided along the front surface of the snow throwing wall portion 31 of the housing member 3, so that the snow is moved farther in the upward upward direction. It can be skipped and snow removal work can be performed smoothly.
Moreover, since the snow throwing wall part 31 and the snow crawl side part 33 are integrally formed, the housing member 3 is troublesome compared with what is manufactured as a separate member and integrated with bolts and nuts or the like. In addition, there is no fear that the bolts and nuts are loosened and separated during use, and a robust structure can be obtained.
