Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to the structure of a ridge cutting rotary in a power tiller.

(2) Prior art In conventional power tillers, the rotary width is narrower than the axial outer width of both wheels, making them unsuitable for cutting ridges in fields. Therefore, when cultivating furrows where power tillers cannot function,
It was done by hand using agricultural tools such as hoes. If you try to overcome the inconvenience and use a power tiller, you will be forced to perform an unnatural task by placing one of the wheels of the power tiller on the ridge to support the tilted machine so that it does not fall over. Moreover, all they had to do was plow the upper layer of soil near the ridge. Therefore, there was a demand for a power tiller that could perform ridge cutting work efficiently.

(3) Problems to be Solved by the Invention In order to meet the above-mentioned needs, the present invention attempts to develop a rotary having a structure that can be easily attached and detached.

(4) Means for solving the problem The power cultivator consists of a conventional rotary part 1 and an attached rotary part 2 that can be attached to the shaft of the main body by extending in the axial direction, and the two can be connected as necessary. A ridge cut rotary with a structure that can be obtained.

(5) Example As shown in Fig. 1, the shaft of the conventional rotary part l is provided with a hole, and the shaft of the attached rotary part 2 is provided with a protrusion, and when the two are connected, the outer end of the attached rotary part 2 Make the length so that it protrudes from the outer width line of the wheel to about 10ca+~20c11. Rotary axis! In order to easily attach and detach the attached rotary part 2 to the JI, and to prevent it from idling, we have adopted a latch structure as shown in Fig. 2, or a hexagonal shaft groove assembly as shown in Fig. 3 (hexagonal shaft, square shaft, groove). (6) Effects Use a power tiller equipped with a rotary as described above to cultivate furrows. The ridge cutting work can be carried out while making full use of the tillage effect without running the risk of the machine falling over due to the cutting work. On top of that.

A power tiller can be used not only to plow along the edge of a ridge but also to the edge of a cliff, making work more efficient and reducing labor in the same way as when cutting ridges.
