Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tilling section arranging device with extremely high tilling efficiency.

Conventionally, a plurality of tilling blades are attached to the circumferential surface of a mounting body such as a tilling tube for tilling. However, if the cultivated land has viscosity or high humidity, it is difficult to till the land and has the disadvantage of being extremely inefficient. In order to attach the tilling blade to the mounting body, the properties of the cultivated land in the tilled state must be taken into account, which also relates to fluid dynamics, and in fact, even those skilled in the art will not be able to achieve superior tillage efficiency. was extremely difficult.

For this reason, in practice, according to the empirical rules of those skilled in the art, a plurality of tilling blades are provided symmetrically on the mounting bodies on both sides of the transmission case, and the positional relationship of the surfaces perpendicular to the axial direction of the mounting bodies +' = , the current situation is that they are installed with an appropriate angular phase difference.

Therefore, in the present invention, the first to sixth tilling blades are disposed on the surface of the mounting body, and the first to sixth tilling blades are sequentially outward from the transmission case side in the axial positional relationship of the mounting body. The first to third tilling blades are installed in sequence so as to have an angular phase difference of approximately 120° from each other in the positional relationship of the surfaces orthogonal to the axial direction of the attachment body, and the fourth tilling blade is installed in the same manner as the third tilling blade. The 4th to 6th tilling blades are installed in order to have an angular phase difference of approximately 180 degrees to the blades, and the 4th to 6th tilling blades are installed in sequence so that they have an angular phase difference of approximately 120°, and these are installed on both sides of the power transmission station. The adjacent tilling blades are provided symmetrically on the left and right, and the horizontal parts of the left and right first tilling blades are made to face outward, and the horizontal parts of the left and right second to sixth tilling blades are made to face inward. The tilled soil does not get used up in between, the ratio of R/i is well balanced, and the tilled soil bulges in the center, but the tilling efficiency is extremely improved and the drawbacks of Mil's method are solved.

The structure will be explained with reference to the drawings.

l is a metal mounting body with a rectangular cross section (hexagonal, square, triangular (see drawing), etc.) or circular cross section, and may be cylindrical (see drawing) or solid shaft-shaped. . The mounting body 1 as shown in FIGS. 1 and 2 has triangular shapes connected in the axial direction, and the 11' partners are configured to have an angular phase difference of about 60°. A through hole 2 (generally formed with the inner diameter of a pipe) facing in the axial direction is provided in the center of the cross section of the segment-shaped attachment body 1, and is installed under agricultural power-driven machines such as tillers and tractors. A mounting body 1.1 is removably installed in a symmetrical manner to the tilling shafts 4, 4, which project from both sides of the projecting transmission case 3, through the through holes 2 thereof. Further, the solid shaft-shaped mounting body 1 is integrated with the tilling shaft 4,
In some cases, it is the tilling shaft 4 itself. 5a, 5b, 5c
, 5d, 5e, and 5f are first to sixth tilling blades, which are perpendicular to the axial direction of the mounting body 1 as a vertical cut part V halfway from the mounting base side, and are curved in the orthogonal plane, and The cross section H on the tip side is bent approximately horizontally to the right or left side in the axial direction of the mounting body 1, and has a two-dimensional curved surface as a whole. In addition, the first to sixth tilling blades 5a, 5
b, 5c, 5d, 5e, and 5f have the function of cutting the cultivated land vertically (in the direction of movement of the agricultural power traveling machine) at the vertical cutting part (■), and the part cut vertically at the horizontal part H The farmland is cut horizontally from the edge to form a large clod of soil, which is then picked up by rotation, turned over and allowed to fall.
1. Next, the first to sixth tilling blades 5a, 5b, 5c, 5d, 5e, and 5f are attached to the mounting body on the right side when viewed from the front of the agricultural power running machine (see the drawings on the right side of Figures 2 and 3). 1 (hereinafter referred to as "right side tilling section"), the first to third tilling blades 5a, 5
The position where b and 5c are successively separated outward from the transmission case 3 side (
With the axial positional relationship of the mounting body 1), the angular phase difference between each R is approximately 120°4 (the positional relationship perpendicular to the axial direction of the mounting body 1), and each base is mounted. It is removably inserted into and fixed to a sheath-like holder on the circumferential surface of the body 1.

That is, in the axial positional relationship of the mounting body l, the first
The tiller blade 5a is fixed to the end of the mounting body 1 in close proximity to the transmission case 3. In the embodiment, the vertical cutting portion V of the first tilling blade 5a
The rear side of the transmission case 3 is slightly inclined toward the transmission case 3 side. This serves to determine the amount of soil that adheres to both sides of the transmission case 3 at the rear of the vertical cut portion (■). The second tilling blade 5b is fixed to the outside of the position of the first tilling blade 5a, and the third tilling blade 5c is further fixed to the outside of the position of the second tilling blade 5b. In the mounting body 1 as shown in FIGS. 1 and 2, the first to third tilling blades 5a, 5b, and 5c are fixed to one triangular mounting body 1. At this time, the transverse portion H of the first tilling blade 5a faces the opposite side (outward) to the transmission case 3 side, and the second tilling blade 5a faces the opposite side (outward) to the transmission case 3 side. Third tilling blade 5b.

The transverse portions H and H of each of 5C are formed facing the transmission case 3 side. Further, the fourth tilling blade 5d is the third tilling blade 5.
Its base is inserted and fixed into a ring-shaped holder on the surface of the mounting body 10 so that an angular phase difference of approximately 180° with respect to C occurs. The fourth to sixth tilling blades 5d, 5e, and 5f are the third
At positions that are sequentially separated outward from the tilling blade 5C (axial positional relationship of the attachment body 1), and the angular phase difference between them is approximately 120°.
The respective base portions are removably inserted into and fixed to a sheath-like holder on the circumferential surface of the mounting body 1 in such a manner that the mounting body 1 has a positional relationship in a plane perpendicular to the axial direction of the mounting body 1.

That is, in the axial positional relationship of the mounting body 1, the fourth
The tilling blade 5d is fixed to the outside of the position of the third tilling blade 5C, the fifth tilling blade 5e is fixed to the outside of the position of the fourth tilling blade 5d, and the sixth tilling blade 6-5 is further It is fixed to the outside of the position of the fifth tilling blade 5e.In the mounting body l as shown in Figs. 1 and 2,
The fourth to sixth tilling blades 5c and 5d.

5f is fixed to another triangular mounting body 1.

At this time, the fourth to sixth tilling blades 5d and 5e.

The transverse lines nH, JT, and H of each of 5f are formed facing the opposite side (outward) to the transmission case 3 side. Next, the first
The sixth tilling blades 5a, 5b, 5c, 5d, 5e, and 5f are arranged on the mounting body 1 on the left side (see the drawings on the left side of Figs. 2 and 3) when viewed from the front of the agricultural power running machine. If you do (
(hereinafter referred to as the "left tilling section"), the positional relationship of the plane orthogonal to the axial force direction of the attachment body 1 with respect to the right tillage section is such that the angular phase angle is the same. The positional relationship in the direction is that they are installed symmetrically. When the right tilling section and the left tilling section are fixed to the left and right tilling shafts 4, the transverse sections H of the left and right first tilling blades 5a, 5a are directed outward,
One left and right second to sixth tilling blades 5b, 5b, 5c
, 5cm 5d, 5d/5e, 5C/5f, and 5f's transverse portions H and 11 are configured to face inward, respectively.

Next, the effects will be explained.

In the present invention, when the first to sixth tilling blades 5a, 5b, 5c, 5d, 5e, and 5f are arranged on the circumferential surface of the mounting body 10, the first to sixth tilling blades 5a, 5b, 5c, 5d, 5e, and 5f are arranged in the axial positional relationship of the mounting body 1. 6th
The tilling blades 5a, 5b, 5c, 5d, 5e, and 5f are provided sequentially outward from the transmission case 3 side, and in the positional relationship of the plane orthogonal to the axial direction of the mounting body 1, the first to third tilling blades 5a .

5b and 5c are installed in sequence so that they have an angular phase difference of about 120° with respect to each other, and the fourth tilling blade 5d is installed so that they have an angular phase difference of about 180° with respect to the third tilling blade 5C. The m16 tilling blades 5d, 5e, and 5f are approximately 12 mm apart from each other.
They are installed one after another so that there is an angular phase difference of 0°, and they are installed symmetrically on both sides of the transmission case 3, with the horizontal portions H, H of the left and right first tilling blades 5a, 5a facing outward, and 2nd to 6th tilling blades 5b, 5b.5c, 5c.5
d, 5d/5e, 5e/5f, 5f cross section H4F
By facing inward, firstly, the tilling efficiency is extremely improved, and secondly, it can be easily replaced with a tilling section arrangement device when forming the ridges.

To explain the action and effect in detail, first, the left and right first tilling mechanism J5
a, At 5a, remove the soil clods attached to both sides of the transmission case 3\cut the soil directly below this, and cross the clods F)
The soil is thrown so as to be held on the outside of the transmission case 3 by the left and right fourth tillers J5d and 5d, and the soil is thrown by the horizontal parts H and H, respectively. Then, the left and right second tilling blades 5b are used to cut the soil approximately at the position of the first tilling blade 5a on both sides of the transmission case 3, and the soil is removed. The C power mace 3 is thrown at each side of the transverse parts H and H, and then the soil is cut with the left and right fifth tilling blades 5e and 5e, and the soil clod is transferred to each of the transverse parts H and H. Then, the left and right third tilling blades 5c are used to cut the soil at approximately the second tilling blade 5b position (reed), and cut the soil to the transverse section H. , H, respectively, and throw the transmission case 3 (l[ll), and finally cut the soil with the left and right sixth tilling blades 5f, 5f, and cut the soil into the transverse parts H, H. If each of them is held on the side of the transmission case 3 and the tilling work is carried out by repeating these steps sequentially, if we consider the transmission case 3 as the center, immediately after tilling is done on the center side (first tilling blade 5a). , the fourth tilling blade 5d) that tills on the outside, and immediately after this, the second tilling blade 5b) that tills on the center side, and immediately after this, the fifth tilling blade 5e) that tills on the outside. The third tilling blade 5C) tills on the center side, and immediately after this, the third tilling blade 5C) tills on the outside (sixth tilling blade 5f), and these are repeated sequentially. (in the axial direction of the body 1), the left and right balance becomes better when tilling,
Between the first tilling blade 5a and the fourth tilling blade 5d, the second tilling blade 5
b and the fifth tilling blade 5e, and between the third tilling blade 5C and the sixth tilling blade 5f, there is a relatively large distance between the third tilling blade 5C and the sixth tilling blade 5f. The soil clods do not get stuck even when the soil is used, and the soil can be tilled without the soil clods always adhering to both sides of the transmission case 3, and these act synergistically to allow extremely highly efficient tilling work.

The tilling state at this time is the center side (transmission case, ′) part)
Although the tillage rises, this does not prevent tillage resistance. Furthermore, this tilling operation is suitable for tilling at a relatively shallow depth (shallow plowing). "Five, left and right second to sixth tilling blades 5b, 5b-5c, 5c" 5d at the outer position,
Since the transverse portions H and H of 5d-5e, 5C, 5F, and 5r face outward, the tilled soil or the tilled soil lumps do not scatter outside the tilling width, allowing orderly tilling work.

In addition, as shown in FIG. 6, the left and right second to sixth tilling blades 5
b, 5b・5c, 5c・5d, 5d・5e, 5e・sr
, sr are alternately replaced and the F bulging board 6 as shown in FIG.
, 5b and 5C, the 0th surface 6a, 6a, and 6a are approximately spiral-shaped, and the 4th to 6th tilling blades 5d, 5 with the 4th to 6th tilling blades 5d, 5
The I-shifting surfaces 5a, 5a, and 5a of e-51 also have a substantially spiral shape, and when cultivated with this, good 4-shifting can be achieved on the left and right sides, resulting in extremely high °ζ1-shifting efficiency. When used together with a gift-forming plate, this top-height cultivating method allows for high-height gift-forming work.

Furthermore, the arrangement of the present invention has the advantage that even a small power source can perform tilling work with high tilling efficiency.

Note that the first to sixth tilling blades 5a, 5b, and 5c.

The angular phase difference of 5d, 5e, and 5f is changed inwardly and outwardly by about 10 degrees.N substantially the same effect as described above is obtained.
