CONSTITUTION:The upper part of a longitudinal pipe 3 is made into a worm wheel 3 and a rotatably pivoted through a ring 7 on a space 6 of lower part equipped in one piece with a casing 5 integrated with a middle lateral drive shaft 4 to be driven by an output shaft of main traction machine. The worm wheel 3a is engaged with a worm 8 and a revolving shaft 9 of the worm 8 is equipped with a handle part 9a. A longitudinal revolving shaft 10 provided with a horizontal bevel gear 11 to be engaged with a vertical bevel gear 4a and with a horizontal bevel gear 13 to be engaged with a vertical bevel 12 is inserted and supported in the longitudinal pipe 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a rotary connected to a traction machine such as a tractor.

(Prior Art) Conventionally, as a means of allowing the rotor shaft of a rotary to turn, there is a method in which a dowel pin is engaged and detached from an adjustment board having adjustment holes provided at predetermined angular intervals. 0 It takes a lot of effort to manually operate the knock bottle.

It is not possible to make fine adjustments to the mouth and turning angle.

C. Adjustment cannot be made unless the device is in a no-load state, that is, the operation is stopped.

Due to the inconvenience of
Currently, it is not possible to fully meet the needs of reverse tillage (so-called upcut) work by rotating 80 degrees.

Furthermore, when the rotor claws move the soil in one direction, the surface of the transmission case that connects the intermediate drive shaft and the rotor shaft gets in the way, making it difficult to build up a sufficient amount of soil.

(Problems to be Solved by the Invention) The present invention has been made in order to overcome such difficulties in the conventional art. It provides a pipe-type rotor.

[Structure of the Invention (Embodiments)] The following will be explained with reference to the embodiments shown in the drawings. In Fig. 1, A is a towing main machine, and R is a rotary connected to this towing machine according to the present invention.

That is, as shown in detail in FIG. 2(a), the upper part of the vertical pipe 3 integrally connected to the lower casing 2 incorporating the left and right rotor shaft mounting shafts 1 is formed into a worm wheel 3a, and the worm wheel 3a The forming part is rotatably supported via a retaining ring 7 in a lower space 6 integrally formed with an upper casing 5 incorporating an intermediate lateral drive shaft 4 driven by the output shaft of the traction machine A.

Further, the worm 8 is engaged with the worm wheel 3a in the lower space 6, and as shown in FIG. form.

As shown again in the same figure (A), there is a horizontal gear in the vertical vibrator 3 that meshes with the vertical bevel gear 4a fixed to the intermediate horizontal drive shaft 4, with the top end 10a facing the inside of the upper casing 5. While fixing the bevel gear 11, the lower end 1
0b facing the inside of the lower casing 2 and a vertical bevel gear 13 fixed thereto which meshes with a vertical bevel gear 12 fixed to the rotor shaft mounting shaft 1. is configured.

(Function) Now, when the handle part 9a is turned in the state shown in Fig. 3, the transmission vertical rotation shaft 10 rotates via the worm gear mechanism (worm wheel 3 and worm 8), and the rotor shaft 14 is rotated by an arbitrary angle. can be done. When rotated by a maximum of 180 degrees, the rotor shaft 14 rotates in the opposite direction, and the rotor claw 1 rotates in the opposite direction.
5 is in the opposite direction.

The above-mentioned turning can be performed even during operation, that is, under load, and the degree of adjustment can be made finely.

Further, since the transmission vertical rotation shaft 10 that connects the intermediate horizontal drive shaft 4 and the rotor shaft mounting shaft 1 has a vertical pipe type casing, soil can be efficiently scattered in one direction.

[Effects of the Invention] As described above, the present invention is based on the correlation between the inclination angle and the traveling speed in contour line work on a slope.
Its true value is demonstrated when it is desired to determine the directional position within the soil bank by adjusting the angle of the rotor shaft, or when it is desired to perform soil leveling (so-called up-cutting) by rotating the rotor shaft 180 degrees in the opposite direction.

In particular, being able to quickly make adjustments to suit the situation without stopping the operation during work significantly improves work efficiency, and since the adjustments can be made minutely, appropriate and accurate positioning is possible.

Furthermore, since the transmission vertical rotation shaft 10 that connects the intermediate horizontal drive shaft 4 and the rotor shaft mounting shaft l is cased in the vertical pipe 3, the so-called surface width is minimized, and soil scattering in one direction is prevented. It is done efficiently.
