It is provided with an engaging portion 19 that removably engages with the end portion of. Numeral 21 is a bolt that fixes the engaging portion 19 to the connecting rod 3 through a notch 23 that is formed by cutting out the end of the engaging portion 19 in the axial direction. 25 is a bevel gear pivotally supported by a bearing 27 inside the support body 17;
Reference numeral 9 denotes an engagement piece that is screwed onto the boss portion 31 of the bevel gear 25, and the bearing 2 is inserted between the bevel gear 25 and the boss portion 31.
7 is held in the axial direction. The engagement piece 29 is removably engaged with a square shaft portion 33 at the end of the transmission shaft 7. 35 is a rotating shaft rotatably supported by bearings 37, 37 in the horizontal direction on the support body 17;
39 is a cover case fixed to the support body 17 with bolts 41, 41, and 43, 43 are snow removal blades provided inside the cover case 39 on both sides of the support body 17. The snow removal blade 43 has opposing circular side plates 45, 4.
The outer side plate 45 is rotatably supported by the cover case 39 by a support shaft 49, and the inner side plate 45 is rotatably supported by a support shaft 49. Spline section 5 at the end of shaft 35
Connected and supported via 1. 53 is a bevel gear fixed to the rotating shaft 35, and the bevel gear 2
5 is engaged. 55 is a snow shovel fixed to the bottom of the cover case 39 with bolts 57, and 59 is a protector fixed to the front of the support 17 with bolts 61, 61.
