Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial field of application) The present invention relates to a side drive type rotary connected to a towing machine such as a tractor.

(Prior Art) Conventionally, there is a so-called side drive type rotary as a means for overcoming an obstacle in tillage of a center transmission case, but on the other hand, since the rotor shaft is a horizontal through shaft, a ridge other than flat plowing is used. It was not possible to adapt to form work (for example, ridges with ridges such as kamaboko-shaped ridges, soil covering work, etc.).

(Problems to be solved by the invention) The present invention has been made in view of the above-mentioned actual circumstances.
By utilizing the advantage of the side drive type and by making the driving means a double sided type, a jointing type in the middle of the rotor shaft is possible, and by inserting and removing it, various types of ridges can be dealt with.

[Structure of the Invention] (Embodiment) Explaining the embodiments with reference to the drawings, in FIGS. 1 and 2 as well, 3 is connected and driven via an output shaft 1 of a towing machine and a direction change gear box 2. A side case 4 is provided at both ends of the intermediate drive shaft via a key groove 5 so as to be movable left and right (that is, the interval can be adjusted).

Further, in the side case 4, a relay rotor tube shaft 10 having a rotor pawl 9 is fixed to a short shaft portion 8 of a rotor shaft to which a driven sprocket 6 facing a drive sprocket 6 is fixed, via a connecting pin 11. . That is, in this state, as shown in FIG. 3, the middle of the rotor shaft is divided to form a predetermined width space.

Further, between the relay rotor tube shafts 10 and 10, a joint rotor shaft 12 to which a rotor claw 9 is attached is fixed via a connecting pin 14 so as to be freely inserted and removed.

FIG. 5 shows only the joint rotor shaft 12 with the rotor claw 9 removed. In the figure, 13 is an adjustment pin hole.

In the above, it is conceivable that the short shaft portion 8 of the rotor shaft may be projected to the outside of the side case 4 and the relay rotor pipe shaft 10 may be fitted thereto. In this case, as shown in FIG. Double work is possible.

(Operation) In order to use the rotor of the present invention having the above-mentioned structure, in flat cultivating, as shown in FIGS. 1 and 2, the spacing of the side case 4 is appropriately adjusted, and the joint rotor shaft is used. Tillage work is performed with 12 connected (through rotor shaft).

Even in the case of flat land, when it is necessary to cultivate and cultivate the crops in the center, it is possible to work with the joint rotor shaft 12 removed (the state shown in FIG. 3).

Next, ridge-shaped ridges with steps like a kamaboko,
In the case of soil cover, as shown in Fig. 3, the splicing rotor shaft 1
2 is removed, the interval of the side case 4 is adjusted appropriately to straddle the ridge, and the earthing work is performed by the rotor claws 9 of the relay rotor tube shafts 10 at both ends.

Therefore, even though it is a side drive type, it is possible to perform ridge work other than flat plowing, and in addition, as in the conventional center drive type, soil can be filled without stirring the inner center of the ridge, so stationary fertilization (without spreading fertilizer to the root Can be placed).

It has been described above that the relay rotor tube shaft 10 can be fitted to the outside of the side case 4 to perform double work on one side.

[Effects of the Invention] As is clear from the above, the present invention is based on the side-drive type and is of the double-side drive system, and the relay rotor shaft 10 is left at both ends of the intermediate joint, and the joint rotor shaft 1
Since it is possible to attach and detach 2 as described above, it is possible to work depending on each condition of the ridge form and the cultivated land, which is very advantageous for achieving the intended purpose mentioned at the beginning.
