Abstract

PROBLEM TO BE SOLVED: To provide a rotary tilling device hardly causing the coiling of a long rush on a tilling shaft by installing helical blades at specific positions of the tilling shaft on which the tilling tines are arranged. SOLUTION: Helical blades 4 and 5 for pushing and gathering tilled soil to the center tilling part 3 between right and left side parts of a tilling shaft 2 on which tilling tines 1 are arranged are installed in the right and left side parts thereof. As the result, the straw waste pushed and gathered by the helical blades 4 and 5 to the center tilling part 3 is buried in the tilled soil by the rotary tilling action of the tilling tine 1 at the center tilling part 3, and the coiling amount of the straw waste or the like on the tilling shaft part 2, and the amount present on the surface of the ground are reduced.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary tilling apparatus, which can be used for tilling and substituting work in a field where a lot of straw dust and rush are scattered.

[0002]

In the field at the site of the rush harvest, it is difficult to tilling where long rush is scattered. The present invention has a configuration of a tilling device that is wound little around a tilling shaft.

[0003]

According to the present invention, spiral wings (4, 5) are provided on both left and right sides of a tilling shaft (2) on which a tilling claw (1) is disposed to push tilling soil toward a central tilling portion (3) therebetween. The structure of a rotary tillage device consisting of

[0004]

According to the present invention, the tilling claw 1 is tilled by the rotation of the tilling shaft 2. The cultivated soil surfaces on both left and right sides of the cultivation shaft 2 are pushed toward the central cultivation unit 3 by the rotation of the spiral blades 4 and 5. At this time, if there is rush or straw debris on the top of the tilled soil surface, it is transferred to the central tilling unit 3 side.

[0005] Straw debris and the like pushed by the spiral wings 4 and 5 to the central tilling section 3 in this manner are removed from the central tilling section 3 by the spiral wings 4 and 5.
Is buried in the cultivated soil by the rotary tilling action of the cultivating claw 1. For this reason, the amount of straw dust or the like wrapped around the tilling shaft 2 can be reduced, and the amount of the waste that appears on the soil surface can also be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A rotary tilling device 6 which can be mounted on a three-point link or the like at the rear of a tractor body has a side drive configuration, and has a side case 8 and a side arm 9 on both left and right sides of a tilling frame 7. Then, both ends of the tilling shaft 2 are axially mounted between these lower ends. 10 is this tillage axis 2
Can be attached to and detached from the side case 8 and the bearing flange at the lower end of the side arm 9. 11 is a tillage cover, 1
Reference numeral 2 denotes an input transmission case having an input shaft 13. The input shaft 13 is interlocked with a PTO shaft on the vehicle body side, and is driven through a transmission mechanism in the input transmission case 12, the tilling frame 7, the side case 8, and the like. 2 can be driven.

The tilling shaft 2 is provided with a socket 14 extending in the axial direction.
Are arranged at appropriate intervals, and the tilling nail 1 is attached. On the left and right sides of the cultivation shaft 2, spiral wings 4 and 5 which are symmetrically twisted are formed, and the central cultivation part 3 is provided with only the tilling claw 1 without a spiral wing provided in the center. . The spiral wings 4 and 5 are set so that the rotation diameter is smaller than the rotation diameter of the tilling claw 1, and only the upper part of the cultivated soil surface tilled by the tilling claw 1 rotates to move the soil from both left and right sides to the center. In a form of pushing.

When the tilling shaft 2 is driven to rotate, the soil surface A is tilled to a constant depth H by the rotation of the tilling claw 1. At the same time, the upper layers of the cultivated soil on both the left and right sides are pushed toward the center by the rotation of the spiral wings 4 and 5, and the cultivated soil surface B is formed. The cultivated soil surface B is generally at a higher position than the untiled soil surface A, but may be at a lower position when the rotation diameters of the spiral blades 4 and 5 are increased.

[0009] Straw chips and the like are often mixed in the soil which is pushed toward the center by the left and right spiral blades 4 and 5, and the straw chips and the like are pushed together to form the central tilling section 3.
Is tilled by the rotation of the tilling claw 3 in the above, and is buried in the soil. Straw chips and the like on the soil surface are hard to wind around the spiral blades 4 and 5 and are buried and moved together with the cultivated soil in the central tilling unit 3, so that the wrapping around the tilling shaft 2 is also reduced.

2 and 3 are different from the above example in that:
At the base of the tilling claw 1, an anti-winding rod 15 is attached in parallel with the tilling shaft 2 to prevent wrapping of straw waste or the like, and the outer circumference of the anti-winding rod 15 is rotatable or fixed. Resin pipe 1
6 is fitted, and it is stopped with the split pin 17. Reference numeral 18 denotes a socket integrated with the center of the winding prevention rod 15, which can be fitted and fixed to the base of the plow 1. Reference numerals 19 and 20 denote pin holes for the socket 14 through which a set bolt for attaching the tilling nail 1 is inserted, and the tilling nail 1.

In FIG. 4, the difference from the above example is that a winding prevention wire 21 for preventing winding of straw dust or the like over the tilling claw 1 in the direction along the tilling shaft 2 is replaced by a wire 2.
The screw rod 22 at one end is inserted into the mounting hole 23 of the tilling claw 1, and is fixed by tightening nuts 24 and 25 from inside and outside. 2
Reference numeral 6 denotes a pipe fitted on the outer periphery of the winding prevention wire 21. 27 is a set bolt of the tilling nail 1.
