DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a tilling claw device, and for example, to a rotary tilling device in which the structure of the tilling claw of a rotary tiller body is improved.

[Conventional technology]

Generally, when cultivating soil, it is desired that the soil clod be large, have reliable reversibility, and low resistance to prevent foreign matter such as fresh leaves from becoming entangled. In other words, what is required for soil preparation is to deeply cultivate large soil clods, turn the soil upside down, and bury surface impurities and organic matter such as compost into the soil. .

Therefore, in the past, for example, bollard plows, disc plows, etc. have been used to meet the above requirements.

However, this type of equipment has problems with ease of use, and its angle with the ground is large, which not only causes the wheels of the tractor to slip on soft ground, reducing efficiency, but also causes a large amount of dirt to interfere with subsequent work. There are problems such as:

Therefore, when tilling with a rotary tiller,
This type of rotary tiller generally has a tiller shaft (rotating shaft)
There is a structure in which a large number of tilling claws formed in an abbreviated shape protrude radially through flanges.

[Problem that the invention seeks to solve]

In the structure of the above-mentioned conventional rotary tiller, the 11 tillers have the above-mentioned shape, so the soil clods are small, the top-to-bottom reversal of the soil clods is insufficient, and deep plowing is usually not possible, and a large number of tillers are required. There are issues such as the need for

Therefore, the present invention has been made in view of the above points, and aims to enable deep plowing with a large clod of soil, to reliably turn the clod upside down, and to bury foreign matter.

[I-come-T first step to solve problems]

The present invention provides a rotating shaft with a plurality of flanges at predetermined intervals, and a tilling claw is removably attached to the outer side of each flange. , each of the tilling claws has a horizontal cutting blade and a vertical cutting type, and the tip of the vertical cutting type is connected to the outer edge of the horizontal cutting claw, and a series of vertical cutting blades and a horizontal cutting blade are attached to the outer edge. It is formed by forming a cutting edge.

[Effect]

The rotary 11 and the rolling body 5 are the chain case 4
The bracket 1 has a rotary shaft 6 rotatably suspended horizontally at the lower end thereof, flanges 7 are fixed at predetermined intervals in the axial direction of the rotary shaft 6, and the outer periphery of each flange 7 is A plurality of tilling claws 8 are arranged symmetrically, and each bolt,
It is removably attached with oak 1-0.

Each of the tilling claws 8 is composed of a horizontal cutting claw 10 and a vertical cutting die 11, which are made of members with substantially the same thickness. A series of vertical cutting edges 14 and horizontal cutting edges 15 are formed in close succession.

Therefore, the horizontal claws 10 of the tilling claws 8 are connected to the rotating shaft 6.
When attached to the flange 7, the mold base 16 extending in a slight arc shape outwardly of the rotating shaft 6 is fixed, and the φλ axis is attached to the tip of the mold base 16 via a curved portion 17. A toe 18 for tilling which protrudes and extends in the lateral direction opposite to the toe 6 is on the right side, and the above-mentioned lateral blade 15 is formed at a distal portion of this toe 18.

The vertical cut type 11 of the ↓j1 claw 8 has a base body 19 that slightly protrudes outward from the rotary shaft 6 when attached to the flange 7 of the rotary shaft 6, and a curved portion 20 is formed on the base body 19. It has a blade body 21 which extends in a straight line toward the curved part 17 of the horizontal claw 10 and has its tip connected to the outer edge 12 of the mold base 16 of the horizontal claw 10. The vertical cutting edge 14 is formed from the outer edge of the L-shaped curved portion 20 to the outer edge of the blade body 21 and is continuous with the lateral edge 15 of the lateral claw 10. Vertical cutting blades 14 of the claws 11 facing each other and horizontal cutting blades 15 of the horizontal claws 10 facing each other
are formed substantially parallel to each other in the attached state.

Next, the rotation @6 of the rotary work body 5 protruding into the chain case 4 is connected to the mission 3 via an interlocking medium consisting of its output shaft and a chain inside the chain case 4! l; JJ connected. A cover 22 covering the upper part of the rotary work body 5 is fixed between the chain case 4 and the bracket, and a leveling plate 23 is elastically supported at the rear end of the cover 22 so as to be able to move up and down. ing. Further, a connecting frame 24 is projected from the front part of the main body frame 1, and a gauge ring 25 is mounted on the connecting frame 24 so as to be height-adjustable.

In this structure, the connecting frame 24 is connected to the three-point suspension structure of the tractor, and the input shaft 2 is connected to the output shaft of the tractor via the power transmission shaft. J:
The height of the gauge wheel 25 is adjusted and set at a predetermined height position.

Next, the tree is pulled by the 1-tractor, and the output shaft of the tractor is driven to input 1I through the power transmission shaft.
Rotate Ill12 in conjunction.

As a result, the machine is advanced, and the rotary tiller 5 is rotationally driven in the up-cut direction through the interlocking medium by the drive of the mission 3, and the forward rotation of the rotary tiller 5 allows each tiller claw 8 to rotate the field. The soil was deeply cultivated with a large clod, and this clot was turned over, and in J, Takoreto, and 6, human γI materials such as straw on the surface of the ground were buried inside the inversion, and the surface became ``-''. J: is leveled by the leveling plate 23.

The size of the nails is 8μ, which is reduced by at least half compared to the conventional wooden nails, so the rotationally driven pips are large and extend in a straight line with respect to the wooden body 16 of the horizontal nails 10.

The vertical cutting blades 14 of the vertical cutting blades 11 of the tilling blades 8 cut vertically deep into the soil approximately at the circumference of the rotation locus, and moreover, the vertical cutting blades 14 Since the vertical cutting blade 11 gradually cuts deep into the soil, the cutting process is smooth with little resistance. Since it is curved in the horizontal direction through the curved part 17, the relative curvature is cut ↓While the toe 18 of the U-claw 8 crosses the vertically cut soil with an unobtrusive pip, the toe 18 cuts deep into the soil. When the soil is tilled as a large clod, it is turned upside down.Also, at this time, impurities such as raw Q that are scattered on the ground surface are buried under the large clod without reaching the M1 claw 8. Buried.

In addition, in practice, the transverse claws 10 and the vertical cutting claws 11 of the tilling claws 8 may be made of the same material, or may be made of mutually different materials.

〔Effect of the invention〕

According to the present invention, a tilling claw is constituted by a horizontal cutting claw and a vertical cutting claw, and the distal end of the vertical cutting claw is connected to the outer edge of the horizontal cutting claw to form a series of vertical cutting blades and a horizontal cutting claw. By forming the blade, it is possible to smoothly deepen the soil to +71 with a large clod, it is also possible to reliably turn the soil upside down, and it is also possible to reliably bury foreign matter on the ground surface.
Not only is it effective because the number of plowing claws can be reduced, but it is also extremely easy to handle because it requires less labor when replacing the grooves.Furthermore, it is easy to handle when one of the members that make up the tilling claw becomes worn and damaged.
