Description

[Detailed Description of the Invention] In other words, the remaining tillage can be effectively removed from the bottom to the sides of the tillage case without the extreme unevenness that occurs in the conventional case, and the assembly and overall structure are simple, and the drive structure is simple. The present invention provides a simple and reliable overall drive system, and allows for good protection of seals such as internal flexible seals, so that they can be suitably implemented.

Next, the embodiment shown in the drawings will be described.

FIG. 1 is a front view showing a partial cross-section of the tilling part of the second tilling rock.
, 6, the support cylinder parts 4, 4 which are inclined with respect to the horizontal direction are fixed by poles 7, 7, and the drive shaft 5 fitted in the bearing 8 fitted to the support plates 6, 6 is attached to the lower part of the tillage case 1. It is installed so as to extend horizontally to both sides through the support cylinder part 4.degree. 4, and a chino 9 to be driven from above is wrapped around the sprocket 10 of the drive shaft 5, so that the shaft can be driven.

Finally, a bearing 11 and an oil seal 12 are interposed on the outer periphery of the support cylinder 4 to fit the inclined cylinder A, so that the inclined cylinder A can rotate at an angle with respect to the drive shaft 5. The base of the tilling claw 2 is inserted into the claw seat 3 protruding from the outer periphery of the slanted cylindrical body A and fixed with a bolt 13. 2
A is configured so that it rotates downward and is driven all the way down to the center side of the tilling case 1.

A pawl shaft 14 equipped with a large number of tilling pawls is fitted to the image front end side of the drive shaft 5, as in the conventional structure, and a spline fitting 15 is fitted.
The center part of the side plate 17 of the narrow bowl-shaped claw seat flange B is fixed to the inner end of the claw shaft 14 by welding W, and the outer end of the inclined cylinder A and the drive shaft are fixed. 5
A side plate 1 is placed on the outer side of the flexible seal 20 installed between the outer circumference and the outer circumference.
1, and the claw seat flange B is formed so that it can be attached to the outer circumference from the outside of the inclined cylinder body A, and claws 1ffi18, 18 are provided at two locations at 120 degree intervals on the outer circumference of the claw seat flange B, respectively. In addition to protruding, both claw seats 1
8 and 18 have tilling claws 2' in a direction perpendicular to the drive shaft 5.
, 2' are fixed with bolt nuts 19, 19,
White melon tips 2'a of both tilling claws 2', 2'.

21a are configured to be successively driven into the lower side of the tilling case 1, facing inward and outward.

In addition, reinforcing plates 21 and 21 are joined to the corresponding two surrounding portions of the claw seat flange B at the intermediate position of both claws 1ffi18, 18 and at a position 180 degrees from that position, and are fixed by welding W, respectively, to strengthen the On the outer peripheries of the plates 21 and 21 and the claw seat flange B, U-shaped cutout hooks s and b are formed.

An engaging protrusion 22 is formed on the outer periphery of the inclined cylindrical body A at a position 180 degrees from the claw seat 3, and the U-shaped hook portion tzb of the claw seat flange B is connected to the claw seat 3 and the engagement protrusion. 22 from the side and engage in the rotational direction.

Therefore, in the tilling operation, when the drive shaft 5 rotates, the pawl shaft 14 rotates to perform the plowing operation, and at the same time, when the pawl seat flange B rotates, the hook portion is removed.

b engages with the engaging protrusion 22 and the claw seat 3, and the inclined cylinder A is forced to rotate.As the inclined cylinder A rotates at an angle, the melon tip 2a of the tilling claw 2 is attached to the tiller case 1. It is driven downward and can be plowed without leaving any residue.

In that case, two tilling claws 2/, 2/ attached to the outer periphery of the claw seat flange B in a direction perpendicular to the horizontal drive shaft 5 at a position near the base end of the tilling claw 2 are attached to the lower side of the tilling case 1. Then, they are driven in line with the tilling claws 2, and on the tiller side, tillage is performed without unevenness as in the conventional method.

In addition, the claw seat flange B can protect the outer circumference of the inclined cylinder A including the flexible seal 20 from the sides, thereby preventing wrapping.

In this way, the present invention allows the inclined cylinder A, which has the tilling claws 2 mounted on the claw seats 3, which can be driven into the lower part of the tilling case 1, to be freely rotatable on the fixed inclined support cylinders 4 on both sides of the lower part of the tilling case 1. A narrow bowl-shaped claw seat flange B fixedly fitted around the horizontal drive shaft 5 extending outwardly of the inclined cylinder A is installed in a covering manner from the side of the inclined cylinder A. At the same time, a tilling claw 2' is attached to the outer periphery of the tilling claw 2' in a direction perpendicular to the drive @5, and the hook part of the claw seat flange B is engaged with the protruding part of the claw seat 3 etc. of the inclined cylinder A in the rotation direction. Since the structure is configured to rotate and drive the tilling case 1, the tilling claws 2 of the inclined cylindrical body A are located directly below the tilling case 1, and the claw seat flange B is located on the side thereof.
By driving in the tilling claws 2' in sequence, it is possible to perform residual tillage without unevenness like in the conventional method, and the assembly and overall structure are simple. The inclined cylinder A can be reliably driven in an inclined state, and the internal flexible seal can be well protected by the claw seat flange B, and the bowl-shaped claw seat flange B is narrow. In addition, the tilling claw 2' that is orthogonal to the drive shaft can be installed near the base end of the tilling claw 2, and the base of each tilling claw can be integrated into the bowl-shaped claw seat flange, further simplifying assembly and the overall structure. There is an effect that can be performed.
