く構成した歩行型耕耘機に関する。[Detailed description of the invention] This invention is based on a cylindrical body that is fixed to the flange of a traveling transmission case that can be divided into left and right halves, with its axis facing in the left and right direction. The present invention relates to a walk-behind cultivator configured to be sandwiched between frames and to connect the frame and a cylindrical body via horizontal bolts.

都合もあつた。 In the walk-behind cultivator described above, conventionally, the cylindrical body on the transmission case side and the pair of left and right frames on the rotary case side are connected via bolts.
As shown in FIG. 4, a pair of left and right cylindrical bodies 014, 014, which are separately welded to the flanges 2a, 2b of the mission case 2 in a horizontal position, are fitted on the rotary case 8 side. A pair of left and right frames 15, 15 are connected to left and right cylindrical bodies 014, 014.
In this case, the left and right cylindrical bodies were welded separately to the mission case 2. This has the disadvantage that manufacturing is troublesome, and when assembling and disassembling the left and right frames for inspection and maintenance,
Since the left and right frames must be handled at the same time while operating a single bolt, assembly and disassembly work is inconveniently complicated. In addition, since the vibrations on the rotary case side are transmitted to the left and right divided cases through the left and right cylindrical bodies, the left and right divided cases vibrate relative to each other, causing the vibrations to interpose between the mating surfaces of the flanges of the transmission case. There was also the inconvenience that one of the gaskets was damaged prematurely and the transmission oil leaked out.

期の損傷をはかる点にある。 The purpose of the present invention is to solve the above-mentioned disadvantages of the conventional structure through simple modifications, improve productivity, facilitate assembly and disassembly work, and prevent early damage to the packing. .
上記目的を達成する為の本考案の特徴構成は、

効果を奏する。 The characteristic structure of this invention to achieve the above purpose is as follows:
The cylindrical body is constituted by a single cylindrical body passing through the left and right flanges of the transmission case, and the cylindrical body is welded and fixed to one flange of the left and right divided case parts, and , the hole of the other flange through which this cylindrical body passes is formed into a blank hole, and the pair of left and right frames are further connected to the cylindrical body via a pair of left and right bolts that are screwed together. , This configuration provides the following effects.

であり、もつて、実用上の利点大な歩行型耕耘機
を得るに至つた。 That is, since the cylindrical body for connecting the left and right frames with bolts is constructed from one cylindrical body and welded to the flange on one side, even when the cylindrical body is welded to the flange, for example, Compared to the above-mentioned conventional structure in which the left and right cylindrical bodies are welded to the flange separately, the cylindrical body can be attached to the flange more efficiently, and it is possible to attach the cylindrical body to the flange using a pair of left and right bolts that are screwed to the cylindrical body. Since the left and right frames are connected separately, it is possible to assemble and disassemble the left and right frames easily while handling the left and right frames separately. This led to the creation of a walk-behind cultivator with great advantages.

るパツキンの早期の損傷を抑制し得る。 Furthermore, the cylindrical body for connecting the left and right frames with bolts is welded to one flange, and the hole in the other flange through which this cylindrical body passes is formed into a blank hole. The vibration of the case is transmitted through the cylindrical body to only one split case, that is, the split case to which the cylindrical body is fixed. The vibration follows the split case to which the body is fixed, and the relative vibration between the two split cases is suppressed, thereby preventing early damage to the gasket interposed on the mating surface of the flange of the mission case. It is possible.
