Description

[Detailed description of the invention] [Industrial application field]

The present invention is connected to a towing vehicle such as a walking type two-wheeled tractor or a four-wheeled riding tractor, and has a large number of tilling claws disposed around the working cylinder shaft on an output shaft protruding from the lower part of the transmission case to both left and right sides. Attach each plowing claw wheel, and this 1jlk claw 0!
The present invention relates to the structure of a rotary working unit in a center drive type rotary working machine which is driven by power etc. mounted on a traction IJ@ through an output shaft and transmits an 1iflI field M1.

[Conventional technology]

This type of center drive type rotary work machine has a so-called simultaneous driving type in which the tilling claw wheels on the left and right sides drive into the soil at the same time, and all the tilling claws on the left and right sides drive into the soil at the same time. There is a so-called discrete driving type in which the AT nails are driven into the soil separately, and the former has a large firing power during the III firing, but has good straightness, and in the attached stand, Although the power required for tilling is small, the straightness is poor, and the steering of the towing vehicle is sometimes adjusted during work.
It is known that it is necessary to The structure of the rotary working part in conventional center drive type rotary work machines is not limited to the well-known examples such as gazettes, and the fitting of the output shaft and the working cylinder shaft by spline fitting, polygonal fitting, etc. Through a fitting and locking means in which the fitting and locking can be changed in the circumferential direction,
A tiller is attached to the output shaft. [Problems to be Solved by the Invention] In the structure of the rotary working part in the conventional center drive type rotary working machine as described above, fitting such as spline fitting or polygonal fitting between the output shaft and the working cylinder shaft is not possible. A tilling claw weight is attached to the output shaft via a locking means, and no matter how the relative relationship in the circumferential direction of one tilling train to the other tilling train is changed, the tilling claws that are driven in at the same time are set in one set. As a result, the I-temporary driving type does not change to a complete individual driving type in which all tilling claws are driven into the soil separately, and
``The driving type has changed to a completely simultaneous driving type in which all the tilling claws at the same position on the left and right sides are driven into the soil at the same time,
One center drive type row 99*m machine cannot be used for both simultaneous driving type and separate driving type, and is a dedicated machine for either simultaneous driving type or single driving type. In view of the above circumstances, the present invention has been developed based on the output of the power source in the towing vehicle, the hard and soft conditions of the Ill field, the age and age of the operator.
Depending on gender, etc., one center drive type rotary work machine can be used for both simultaneous driving and individual driving. When changing the relative relationship of one tilling train to the other tilling train, the relative phase difference between one Asakaze windmill and the other tilling train - during rotation, the installation state of simultaneous driving and the installation state of separate driving become the same, respectively. It is an object of the present invention to provide a structure of a rotary working part that can be switched to a simple holding part one by one.
