[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary cultivator and a method for repairing a storm using the rotary cultivator.

[0002]

2. Description of the Related Art In rice cultivation, a rotary tiller is used to perform plowing work, a water filling work, a soil tilling work with a soil tiller installed behind the rotary tiller, a plastering work, a rough scraping work, and a scraping work. Planting work has been done by rice transplanters, and the most important factor for rice cultivation is said to be water management.

[0003] That is, it is essential to carry out cold water repair work for deep water at the time of rooting, shallow water at the time of parting, complete drainage at the time of mid-drying, irrigation from the earing formation stage to the earing stage, and deep water at the heading time. . Further, there is a rotary cultivator which is equipped with various work implements on a rotary cultivator and is provided with auxiliary power take-out means as shown in FIG. 14 in order to drive the work implements.

In FIG. 14, the bevel gear means 3 in the gear box 2 of the side drive type rotary cultivator 1 is
Technology that links the PTO shaft 4 (1 in the conventional example) or technology that connects the PTO shaft 6 to the shaft end of the claw shaft 5 (2 in the conventional example).
was there.

[0005]

The PTO shaft 4 according to the conventional example 1 described above is advantageous for mounting a dusting machine or the like on the cultivator 1 and driving it, or for driving a car wash pump. However, it was unsuitable for extracting power from rotary ditchers, mowers, drilling machines, etc. In the conventional example 2, P
Although it is possible to connect the rotary groover to the TO shaft 6, the pawl shaft 5 has to be driven, resulting in a waste of power consumption.

Further, in the conventional repair work for ridges, a rotary tiller can be used for plowing, pouring water, and soiling, but lifting the soiled soil up to the top of the ridges for scouring is manual work. Although this lifting work is a heavy-duty work and this mechanization is demanded, since the mounting position of the PTO shaft according to the conventional examples 1 and 2 is fixed and the claw shaft 5 is driven, the soil excavation soil is removed. It was something that could not be lifted.

Therefore, according to the present invention, the auxiliary power is generated by the hydraulic motor so that the motor can be independently started and stopped, and the mounting position of the motor can be changed according to the working device. It is an object of the present invention to provide a tiller and a method for repairing a ridge that mechanizes embankment lifting using the tiller.

Regardless of whether or not the claw shaft 15 is driven, when the hydraulic motor 37 is started, the work implement 54 rotates, and the groove cutting work at the time of mating is performed as illustrated.

At this time, the hydraulic motor 3 is moved by the first position changing means 30 in the left-right direction of the position changing mounting means 56.
By changing the position of 7 in the left-right direction, the tiller 1
The drain groove U can be formed immediately after the inside of the plowing width of 7 and immediately after the outside of the plowing width. In addition, the output shaft 48 of the hydraulic motor 37
When the position is changed to the vertical direction, the drainage hole P can be formed by the working device 54 shown by the screw type hole puncher as shown in FIG.

Further, as shown in FIGS. 8A and 8B, the second vertical position changing means 3 in the position changing mounting means 56.
4, by changing the position of the hydraulic motor 37 upward, the weed cutting on the top surface can be performed by the work implement 54 shown by a mower. In addition, when cultivating rice, the rotary tiller 1 is operated after plowing work and water filling (see FIG. 9A).
After attaching the earth gathering plate to the ridge 0 and advancing along the ridge T, as shown in FIG. 9 (B), after gathering the embankment G, replace the earth gathering plate with a screw type earth lifting machine. By mounting the work implement 54 shown on the upwardly inclined output shaft 48 and activating the hydraulic motor 37, the embankment G is also lifted up to the elevation surface and the top surface of the puddle T, and then the rotary cultivator 1
You can repair the bruise by attaching a burr coater to the No. 0 and blazing as shown in FIG. 9 (D).

As described above, the hydraulic motor 37 is attached to the output shaft 48 so that the hydraulic motor 37 can be adjusted in the left-right direction, the vertical direction, and the angle according to the type and working form of the work implement 54. You can freely take out the auxiliary power by.
