のである。 Conventionally, as a belt cover device for this type of cultivator,
For example, the one described in Japanese Utility Model Publication No. 57-7880 is known. In this case, the front cover and the back cover are provided independently, but the back covers are also attached individually on the left and right sides, and one of the back covers is attached to the mittens through multiple stays and mounting brackets. The other back cover is fixed to the engine case, and the other back cover is fixed to the engine.
The front cover is connected to the back cover of these through fittings. Therefore, when attaching the back cover and one of the front covers to the transmission case, some are attached using stays, but it is difficult to align the attachment positions, and other back covers are attached to the engine using mounting brackets. Furthermore, the other end of this fixture is in contact with the inner surface of the front cover and is secured with bolts, so engine vibrations are directly transmitted to the front and back covers, preventing cracks. There are defects such as noise generation. Therefore, in view of these defects, this invention was improved in an attempt to overcome this problem. In the attachment device for the belt cover of a power tiller, which has a front cover with a letter-shaped cross section and a back cover that covers the inner side of the belt on the machine side, which are formed independently from each other, the belt cover is wound between the driving pulley and the passive pulley. Attaching a belt cover for a power tiller in which a front cover with a roughly U-shaped cross section that covers the outer periphery and outer side of a hung belt and a back cover that covers the inner side of the belt on the machine side are formed independently from each other. In the device, a cover stay is attached to the rear outer part of the flywheel cover so as to follow the lateral outer surface of the flywheel cover with a gap, and this cover stay has a cover stay that intersects with the flywheel cover at the upper and lower ends. The mounting seat protruding in the direction
A back cover mounting seat is provided along the lateral outer surface of the flywheel cover at the rear, and a cylindrical bulge formed to cover around the input shaft is attached to the front of the back cover attached to the fuselage. Attach the front cover to the mounting seats at the top and bottom ends of the cover stay and the back cover by tightening the bolts to the back cover mounting seats through the long holes provided in the front and rear direction. A belt cover for a power tiller that is fitted onto the outside of the front cover and is attached by tightening bolts to the front cover through long holes on the outer periphery of the front cover. It is an object of the present invention to provide a belt cover for a tiller that can be attached.
