This has the following drawbacks.
Conventionally, the rotary shaft (cultivation shaft) of the rotary tiller of the management machine (mini-cultivator) and tractor is parallel to the prime mover, the work machine, or the rotary drive shaft and bearing part of the earth work site. Therefore, when we set up a ridge in the field and cultivated it between the ridges for weeding, etc., the soil of the raised ridge was broken and leveled.

In addition, in the mulching work that weeds the leek, etc., raised to the roots of the leek, etc., gradually by weeding such as leek cultivation, etc. Each of these was often done manually with long handle weeds, which was hard work.
The present invention has been made to eliminate the above drawbacks.

A frame 2 is also provided above the drive shaft 1 of the rotary tiller portion of the management machine (mini-cultivator) and the tractor. The front and rear adjustment frames 4 having the connecting position adjusting holes 3 penetrating the left and right ends of the frame 2 are engaged, and the vertical adjusting lever 6 having the connecting position adjusting holes 5 penetrating the front and rear adjusting frames 4 is provided. The locking pin 7 and the snap pin 8 are connected so that the holes overlap with each other, and a rotary bearing portion 11 having a bearing 10 is arranged at the lower portion of the vertical adjustment lever 6. One end 15 of the rotary shaft 14 provided with a universal joint 17 is provided on the other end 16 of the rotary shaft 14 on the drive shaft 1 side of the rotary tillage portion, and the through hole 1 of the drive shaft 1 of the rotary tillage portion is provided. And penetrating the clevis pin 20 in the through hole 19 of the universal joint 17, locked with a snap pin 9 is mounted with them the prime mover and rotary plow upper bolt 24 and a nut to the frame 2.
The present invention is a rotary device capable of adjusting the angle of a rotating shaft having the above configuration.

  Seen from the front center (plane, bottom center), the angle can be adjusted vertically from the center of the two left and right rotation shafts. In this case, it is possible to cultivate the soil of the raised ridge without breaking it as much as possible.

In addition, as in the cultivation of green onions, etc., it is also possible to reduce the height of the mountain and the height of the valley in the littering work that gradually breaks up the soil of the firewood that is raised to the growth of the green onion etc. Accordingly, the angle of the tillage shaft can be adjusted up and down, and the angle can also be adjusted in the front-rear direction with respect to the traveling direction. it can.
In addition, by passing through the center of the ridge, weeding and digging can be done at the same time from the top of the raised ridge to the left and right valleys, saving labor.

  It is the perspective view which mounted | wore the management machine (mini-cultivator) with this invention.   It is a front view of the present invention.   It is a right view which shows the modification of a rotating shaft angle adjustment mechanism.   It is a partial expansion perspective view which shows the arrangement structure of a rotating shaft angle adjustment mechanism.   It is a partial expansion perspective view which shows the arrangement structure of a drive shaft and a rotating shaft.

Embodiments of the present invention will be described below.
At the upper part of the drive shaft 1 of the center drive type rotary tiller of the management machine (mini tiller) and the riding tiller, a frame 2 is also provided for mounting on the prime mover and the rotary tiller, and two rotations are provided. A front / rear adjustment frame 4 having a through-hole connection position adjusting hole 3 is engaged with both left and right ends of the frame 2 so as to be a shaft (cultivation shaft), and a through-hole connection position adjusting hole 5 is provided in the front / rear adjustment frame 4. The provided vertical adjustment lever 6 is connected using a locking pin 7 and a snap pin 8 so that the holes overlap each other, and a rotary bearing portion 11 having a bearing 10 is disposed below the vertical adjustment lever 6. One end 15 of the rotary shaft 14 having the tilling claws 12 and the tilling claws 13 is fitted into the rotary shaft 14, and a universal joint 17 is provided at the other end 16 of the rotary shaft 14 on the drive shaft 1 side of the rotary tillage portion. .
A clevis pin 20 is inserted into the through hole 18 of the drive shaft 1 of the rotary tillage part and the through hole 19 of the universal joint 17 and is locked by using the snap pin 9, and the bolt 24 and the nut are attached to the frame 2 and their prime mover and the rotary tillage upper part. And a safety cover 21 that covers the rotary shaft 14, the tilling claw 12, and the tilling claw 13 is provided.
The present invention has the above structure.

By changing the connection position of the connection position adjustment hole 3 of the front / rear adjustment frame 4 and the connection position adjustment hole 5 of the vertical adjustment lever 6, the angle of the two left and right rotating shafts 14 can be adjusted in the vertical direction and the front / rear direction. It becomes.
When this is used, the angle between the two rotating shafts 14 is adjusted, and it is only necessary to cultivate the space between the ridges.

  In the present embodiment, the rotary claw 12 is provided with the tilling claws 12 and the tilling claws 13, but the tilling claws 12 and the tilling claws 13 may be replaced with, for example, a disk or a resin rotor, In the case where it is desired to break up the soil of the raised ridges such as green onion cultivation little by little, or to raise the soil little by little, a spiral screw may be used instead.

In addition, depending on the model of the management machine and the rotary tillage machine, there is a model in which the drive shaft 1 of the rotary tillage unit is not provided with the residual tilling processing mechanism directly below the drive case 22. You may arrange | position the pipe with a residual tilling process nail | claw.
Note that the function, shape, processing method, arrangement, and position of any member in the present specification are not limited by the corresponding features included in the name.
